Title: A video tape recorder
IPC: H04N5/783
Filed: 1980-10-16
Abstract: In a video tape recorder having a still picture reproducing function, a circuit arrangement for automatically shifting a still picture noise band caused by misalignment between the pick-up head path and the recording track to the outside of the reproduced still picture. A picture stop interval is provided at a position corresponding to the phase to which the noise band is to be shifted. When a drop-out pulse signal indicating the presence of noise occurs outside the stop interval, a still picture reproducing command is invalidated to thereby allow a drive motor to be operated, which motor is stopped when the drop-out pulse falls within the stop interval to thereby set the picture still. A still picture of high quality can be reproduced with an improved stability.

Title: An electrically driven machine for processing rods, tubes and the like
Inventor: WAGNER RUDOLF
IPC: B23Q11/08
Filed: 1982-12-20
Abstract: A machine for processing rods, tubes and the like has an electric motor which is disposed within a housing (12). Located in the housing (12) is a fan (21) which sucks cooling air into the housing (12) through air intake openings (22). Located in the region of the air intake opening (22) is a cover (29) extending substantially over the cross-section of the air intake opening (22), which cover (29) comprises a passage (35) for the air sucked in. The cooling air passes to the outside through an air outlet opening (28) in the housing (12) which is covered by a filter (45). The cover (29) forms protection against contact and prevents the admission of water and granular foreign bodies into the housing (12). The filter (45) at the air outlet opening (28) likewise prevents the penetration of foreign bodies. The cover (29) also reduces the noise level of the motor. <IMAGE>

Title: Improvements in partitioning between livestock cubicles
Inventor: SCOTT FERGUS ROBERT TRENT
IPC: A01K1/00
Filed: 1983-01-31
Abstract: A partition for separating adjacent cubicles in which cattle are housed has at least the bottom rail of a conventional parallel-rail partition substituted by a medal U-shaped vertical frame 12 welded to the top rail 10 symmetrically with respect to the partition. The depth and width of the U are sufficient to block the passage of an animal from one cubicle to the next whilst leaving a free vertical space at each end of the partition in which the animal's legs and head can move as it rises from the recumbent position. Thus its legs are not trapped under a conventional rigid bottom rail. In the preferred construction, the depth of the frame is about three quarters the height h of the top rail above floor or bed level and its width is between one half and two thirds the length of the cubicle. <IMAGE>

Title: Fail-safe switching circuit
Inventor: LILLEKER GEOFFREY
IPC: H03K17/94
Filed: 1984-06-21
Abstract: The invention relates to a fail-safe switching circuit for electrical or electrically controlled equipment comprising a switch (2), eg a dead-man's handle, for switching the equipment ON and OFF and a Wien bridge (1, R1, R2, R4) connected in circuit from the switch to equipment, one leg of the Wien bridge including the switch (2). In normal use, closing the switch puts the Wien bridge in balance, giving a zero voltage output, and opening the switch puts the Wien bridge out of balance to produce an output voltage, the detection of which turns a transistor (TR2) off to deenergise a relay and shutdown of the equipment. Any short circuit fault occurring is inevitably of a resistive nature and the Wien bridge cannot be put in balance even with the associated switch closed. <IMAGE>

Title: Limited slip seal
Inventor: FIELDS PAUL J
IPC: F16J15/18
Filed: 1984-06-22
Abstract: A limited slip seal adapted for use in sealing the space between two relatively rotatable relatively inclined annular surfaces 18,20. The seal includes an annular seal body 24 having so a first seal surface 26 adapted to annularly contact one of the surfaces over a relatively small surface area. The seal further includes a second seal surface 28 which is adapted to annularly contact the other annular surface 18 over an area which is much greater than the first surface area. The seal body is biased as by a spring 30 against both surfaces in such a manner that the slippage of the larger surface area seal during rotation of the annular surfaces is limited. The biassing may be generated by the resilience of the seal body itself (Fig. 4). The seal body may be provided with one or more annular edges for sealing engagement with the one annular surface (Figs. 3, 5, 6, 7, 8). <IMAGE>
