International Classification:

H04L009/00

US Classification:

713/201000

Abstract:

A system for processing data requests from clients via a network is disclosed. The system has an application server coupled to a network, and a semantic firewall to pass and filter the content between the application server and the clients. The application server provides content from a database to the clients via the network, and the semantic firewall restricts access to a portion of the content for one or more clients.

US Classification:

725 28, 725145, 725 92, 725153

Abstract:

Segmentation messages indicative of locations of upcoming events, such as the start and end of programs and program portions, and/or rights related to the programs and program portions, are used by cable systems and the like to store programs and program portions for later retrieval and transmission to customers on request. Storage, retrieval and management of programming is thereby facilitated. Methods and systems are disclosed.

Filed:

Nov 13, 1981

Appl. No.:

6/320988

Inventors:

John W. Callahan - Peapack NJ

Assignee:

Pennwalt Corporation - Philadelphia PA

International Classification:

F16H 120
F16C 110

US Classification:

744248R

Abstract:

A flexible shaft has its outermost layer of windings provided with a helical gap along length of the shaft. The helical gap is formed by a flexible shaft winding machine which is programmed to uniformly intermittently discontinue coiling the windings very closely in the outermost layer to thereby uniformly leave a continuous helical space along the shaft length which forms the helical gap. A smooth-bore nut has a pair of transversely disposed pins or screws extending partially thereinto for engaging the helical gap to cause the nut to travel along an unlimited length of a rotating flexible shaft which may be curved. The pins or screws are spaced to ride in the helical gap a pitch distance apart.

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

H01J 37244

US Classification:

250287

Abstract:

A mass spectrometer is disclosed having a detector that detects the induction of a charge as an ion pulse passes by the detector and provides a representative output signal thereof. The inductive detector output signal is present regardless of the presence or intensity of preceding ion pulses and also the inductive detector is relatively insensitive to the velocity of the charged particles being detected. Further, the inductive detector does not destroy the vast majority of the ion pulses that it detects so that the non-destroyed ion pulses may be further analyzed by spectrometers attached in tandem.

Appl. No.:

6/488244

Inventors:

John W. Callahan - Peapack NJ

Assignee:

Pennwalt Corporation - Philadelphia PA

International Classification:

B65G 5340

US Classification:

406132

Abstract:

Apparatus which controllably meters dry powder from a powder supply chamber falling through a vertically disposed axial passageway interconnecting the supply chamber with a mixing chamber therebelow for forming an air-powder mixture therein for transport to a desired site. A tapered plug member is bonded to a bimorph bender comprising a piezoelectric element bonded to each face of a thin, flat, cantilevered metallic beam which is deflectable by a dc bias or driving voltage applied to the bender to cause the tapered plug to penetrate or move within the passageway, thus varying width of annular gap formed between the plug and passageway, and hence, amount of powder capable of falling therethrough. An oscillating voltage may be impressed upon the piezoelectric elements to cause the deflected beam to additionally be vibratorily displaced in accordance with the frequency of vibrations of the impressed oscillating source.

Appl. No.:

5/909413

Inventors:

John W. Callahan - Peapack NJ

Assignee:

Pennwalt Corporation - Philadelphia PA

International Classification:

B23P 700

US Classification:

2940208

Abstract:

A sleeve member interconnects an upper and lower length of replacement casing, which lengths are associated with the vehicle speedometer and transmission respectively. The upper length is crimped into one end of the sleeve member while the lower length is slidably adjustable with the remaining portion thereof. By a series of process steps, the interconnected lengths of replacement casing will contain a replacement rotatable flexible shaft cable therein, which cable is provided with a square tipped cable fitting at each end thereof, one of which operatively engages the vehicle speedometer while the other engages the transmission. By virtue of the slidably adjustable lower casing length within the sleeve member, proper protrusion of the cable fitting square tips is insured. The adjustable length of casing may then be rigidly crimped into the sleeve member. Thus, no preformed square ends are required on the replacement cable and yet the process permits the use of replacement casing material having an inside diameter no larger than that of the original equipment casing, the latter feature providing a quietly operating aftermarket device.
