Patent DE-3375966-D1 (DE)
Title: Electrical connectors with protective hood
Inventor: PELCZARSKI WALTER J
IPC: H01R13/516
Filed: 1983-08-31
Granted: 1988-04-14
Abstract: A protective hood for a rectangular electrical connector is described in which the hood is provided with flexible sidewalls. A locking member and cam member is provided adjacent the free edge of each sidewall near the opening to the recess in the hood into which the connector is positioned. During assembly of the hood to the connector, the cam members flex the sidewalls away from the connector to prevent the locking members from locking onto the connector. When fully assembled, the cam members release the sidewalls to allow the locking members to lock onto the connector with an audible "snap".The hood may be unlocked arid removed from the connector by manually flexing the hood sidewalls away from the connector. In one form of the invention this may be done by manually applying force to one end of the bottom of the hood.

Granted: 1996-04-04
Abstract: A method of recording a digital data signal, such as an audio PCM signal, onto a recording medium in the longitudinal direction thereof, together with an apparatus which is suitable for this recording method. Even-numbered words and odd-numbered words in a digital data signal are recorded on a first track group and a second track group, respectively, which are separated from each other in the widthwise direction of a recording medium, to prevent a series of words becoming error words because of, for example, a flaw in the recording medium in the longitudinal direction thereof. The data format is changed at the input and output of a recording encoder to enable an error correction code and a recording circuit to be used in common for digital tape recorders which have different numbers of tracks, e.g., n tracks and 2n tracks. When an error correction code is recorded in such a manner that one word in the digital data signal is divided into a plurality of symbols which are formed into an error correction code, a plurality of symbols of the same word are recorded at a position at which error correlation is strong, making effective use of the error correction capacity of the error correction code.

Title: Semi-conductor motor control system
Inventor: BECK WILLIAM H
IPC: H02P25/03
Filed: 1985-02-08
Granted: 1988-11-17
Abstract: An input SCR rectifier bridge (14) provides a direct current output in response to the three-phase AC input. The dc is supplied to a diverter network (18) which is connected between the input bridge and an output SCR inverter bridge (20). The output inverter bridge converts the direct current back to three-phase alternating current for supply to the three-phase electrical motor (12). In the diverter network the direct current input is applied to a tank circuit including a capacitor (42) and inductor (44). The capacitor is connected through a diode (46) across the dc power lines (28,30). A thyristor switch (50) is connected to the tank circuit. When it turns on the thyristor shunts direct current from the inverter  and effects reverse charging of the capacitor. The resulting reverse charge stored on the capacitor turns off the thyristors or SCRs of the inverter to provide forced commutation. Following the reverse charging step, the thyristor switch is turned off by current flowing through a diode (52) to couple the full cycle resonance of the tank circuit.

Title: Safety switch-off equipment for mechanically moved tools, especially automatic welding guns
Inventor: DINSE WILHELM
IPC: B23K9/12
Filed: 1986-05-30
Granted: 1989-02-23
Abstract: A safety stoppage or disconnection apparatus for mechanically moved tools, particularly automatic welding guns, having a swashplate and an assembly casing, between which are arranged one or more spring elements and a switch operated by the relative movement between the swashplate and assembly casing. It is necessary with such safety apparatuses to prevent other adverse rotary movement between the swashplate and assembly casing. This is brought about by two facing bolts, whose heads projecting beyond the outer wall of the swashplate are guided in slots, which run in the inner wall of the assembly casing in the intended swashplate movement direction. The bolts are spring-loaded and preferably spherical. The bolts with the spherical heads on the one hand reliably prevent a rotary movement between the swashplate and assembly casing and on the other hand do not prevent the relative movement and a slowing down movement necessary for the operation of the switch, even if the swashplate is tilted and tipped by the relatively large moment exerted by the tool against the swashplate. Following tool relief, the swashplate returns in an unimpeded manner to its initial position.

Abstract: Apparatus and methods for stuffing food casing to produce sausage products with a high degree of dimensional uniformity for prepackaging applications. Substantially flat terminal end (14) portions for higher product yields are prepared by a stuffing sequence which includes a time delay from shut down of the meat pump to actuation of the end-closure device. The length of the delay in actuating the end-closure device is dependent on the time required for pressure in the stuffing horn to dissipate after shut-down of the meat pump. Substantially flat terminal ends may also be made by introdcing a time delay from actuation of the end-closure device to removal of the sizing ring from the end of the horn so that the length of the delay is also directly proportional to the viscosity of the meat emulsion.
