Strategic Financial Communications Corp. - New York NY

International Classification:

B42F 1322

US Classification:

402 30

Abstract:

The invention is a notebook having a cover and a selectively openable and closable binder mechanism which can support a plurality of pre-punched, loose-leaf sheets. The binder mechanism includes the following: (a) an elongated rigid plate; (b) a hollow tubular support channel including upper and lower portions fixed to the plate and in coaxial relation with one another; (c) an opposed pair of pivotable clam-shell sheet retainers which are cooperatively associated so as to define a closed, generally elongated cylindrical, sheet holder in a first radial position and an open split cylinder in a second radial position; (d) the clam-shell sheet retainers include a rod-like pivot which pivot is slidably mounted in the support channel for a limited axial movement between a first normally restrained position and a second normally unrestrained position; (e) a first spring which biases the pivot towards its first normally restrained position; (f) a second spring which radially biases the clam-shell sheet retainers apart towards their open position; and (g) a cam associated with the support channel and operative to force the clam-shell sheet retainers into their closed position.

US Classification:

351203

Abstract:

A vision and hand/eye coordination testing machine includes a front panel sub-divided into a grid-like array. Each array position is either a lamp position or a dummy position, the two being visually indistinguishable. Panel lamps are illuminated in one of three alternative modes, namely: a pursuit mode wherein lamps are illuminated according to a prescribed continuous pattern and the subject must follow the pattern by moving his/her eyes; a saccadic hand/eye mode wherein the subject focuses on a centrally located alternating fixator lamp and actuates a switch at array lamp positions; and a second hand/eye mode, similar to the saccadic mode, but the fixator lamp remains off. Timely switch actuations are counted and actuate respective indicators in a remote monitoring unit. In both hand/eye modes the lamps are illuminated in a random or other sequence unrelated to lamp position. A separate linear array of lamps is used in a fourth or sports mode in which the lamps extend toward the subject from the housing and are momentarily illuminated in sequence to simulate a ball moving toward the subject.

Abstract:

A countdown timer designed for counting down predetermined intervals of time and periodically announcing the progressive elapse of the countdown period thru the use of a voice synthesizer. The time interval between the spoken announcements is decreased as the end of the period approaches. An automatic restart period is incorporated which recycles to a predetermined time to begin the countdown again the number of the restart cycle being counted down is displayed.
