Title: Film deceleration unit
Inventor: SHAW WILLIAM C
IPC: G03B21/00
Filed: 1991-08-12
Granted: 2002-05-28
Abstract: A projector having a rolling loop film transport mechanism is provided with a film decelerating cam unit (52) that is located in adv-ance of the aperture of the projector. Deceleration pins (66) carried by a pair of verti-cally spaced arms (62) that project from the cam unit, en-gage in upper and lower mar-ginal perforations in the film and travel with the film tow-ards the aperture and deceler-ate the film as each frame is advanced. The cam unit in-cludes two cams (56, 58), one of which causes the decelerat-ing motion of the pins, and a return motion in the reverse direction, while the other cam (58) causes the pins to adv-ance and retract into and from the film path respective-ly. By positively retracting the pins, their return movement against the direction of film travel can take place independent of the motion of the film. As compared with the prior art, acceleration forces and resultant stresses on the cam are reduced and the cam unit can operate at higher frame rates and/or with smaller rotor gaps.

Abstract: A caller-ID telephone station having a caller-ID based directory of telephone numbers automatically adapts its directory to compensate for a change to the area code in which the telephone station is located. The caller-ID telephonestation stores the area code for all incoming caller-ID telephone numbers along with each telephone number received. The telephone station also stores its home area code. This home area code is inputted by a user during an initialization step when the telephone station is first installed, moved to a different area code or the station's locale is changed to a different area code. In response to a request from the user for dialing a telephone number entered into the directory, the telephone station compares the stored area code received as part of the caller-ID telephone number with thestored home area code and determines from this comparison whether to include or omit the received area code as part of the dialed telephone number. In one disclosed embodiment, the received area code is included in the dialed telephone number only if the received area code and the home area code are different.

Granted: 1999-05-04
Abstract: In the case of liquid crystal polymers, on the one hand the rigid molecule chains and on the other hand possibly  present  fibrous  reinforcing materials  are aligned substantially parallel to a weld or flow line, as a result of which the physical properties are absent in the region of the weld or flow line. It is an object of the invention to provide a possible way of preventing weld or flow lines being able to occur at 111. For this purpose, the liquefied material is subjected to a shearing energy from entry into the injection mould over at least part of the length of the workpiece. This shearing energy is produced by relative movement between  two surfaces of the mould parts.
