US Classification:

132278

Abstract:

A barrette for holding hair having an improved wireform latch in which the barrette includes a top plate having upstanding pivots and upstanding receptor hooks, and the wireform being a semirigid wire in a frogleg shape which is put in tension parallel to the plate by compressing the legs together to allow hooking of the legs to the pivots and in rotary tension away from the plate by compressing hair between the plate and wireform by such hooking.

International Classification:

H01N 714

US Classification:

379 53

Abstract:

A slide projector control module and control system to operate one or more slide projectors located at one or more different locations, each slide projector having a slide tray and being connected with the control module. Conventional telephone lines are used to connect each slide projector and each module at each location for viewing the same slide at all locations. Slide projectors at all locations are capable of being rendered operative and the slide projector is operative only at its location with its associated control module when properly selected. Each module includes switches to connect and disconnect the remote and local projector from a key pad which provides touch tone signals capable of being muted from telephone lines. The control system is operable from a local or remote site to permit conferences to discuss a series of visuals and to recall the visuals as needed at each site of a multi-site and/or multi-person conference. The slide projector control module is provided at each site and is capable of operation as a master or a slave to permit each site to be a master or slave operable from a local or a remote site, so that the slide viewed at each site presents the same visual.

TIE/Communications, Inc. - Stamford CT

International Classification:

H04M 166

US Classification:

179 18DA

Abstract:

The invention is a toll restricting method and apparatus which restricts toll telephone calls from telephone stations by interrupting dialing sequences if from the station there is dialed (a) a restricted digit during a first predetermined number of digits, or (b) more than a second predetermined number of digits. Restricted dialing sequences are interrupted by disconnecting the telephone from the central office line for a period sufficient to release all the registered digits and to return central office dial tone to the telephone. Also provided are a method and apparatus for allowing absorb digits to be dialed before the counting of digits begins. A method and apparatus are additionally provided for restricting a telephone from which delays between digits dialed are greater than a predetermined time delay.

Abstract:

Curing agents for epoxy resins composed of (a) the reaction product of a co-reactant comprising either an epichlorohydrin (co) polymer or a (co)polymer of a chlorovinyl acetate, chloroalkyl acrylate with an organic amino compound containing at least one active hydrogen and having a pK. sub. B value within the range of from about 7 to about 9, preferably imidazole and substituted imidazoles; (b) an N-fatty imidazole and (a); (c) an N-fatty imidazole and an elastomeric polymer are disclosed. The curing agents are essentially water insoluble and give rise to epoxy resins which may be cured at relatively low temperatures below about 100. degree. C. The epoxy resins are suitable for use as adhesives, coatings and in composite applications.

International Classification:

G06F 17/30
H04L 29/08

Abstract:

In some embodiments, a method can involve identifying content items associated with a user account at a content management system that have a follow setting enabled for tracking changes to the content items. The method can involve monitoring, based on the follow setting, content modifications from other user accounts and read-unread status events from the user account. The method can involve identifying, for a content item, an event triggering a different read-unread status than a current read-unread status set on the user account for the content item. The method can further involve modifying the current read-unread status to the different read-unread status and updating the content item to include a visual indication of the different read-unread status.

International Classification:

Abstract:

A document preview system provides previews of a native document to client devices. The previews include comments associated with native objects in the native document. The document preview system identifies bounding areas in the preview associated with the native objects, which may be identified by the rendering markers applied to the native document prior to rendering. Using the bounding areas, the document preview system identifies comments for the native document and determines the location to display the comment using native objects associated with the comment. When a new comment is received from a user for a preview of a native document, the document preview system determines native objects for the new comment that match a user's selection for placing the new comment. The new comment is inserted with the native objects in the native document.
