Title: Door closing device
Inventor: ADAMS NEIL JOHN IRWIN
IPC: E05F3/10
Filed: 1982-10-12
Abstract: A door closing device comprising a cylinder 12 in which a piston 13 is slidably located. A spring 25 urges the piston 13 towards one end and a rod 21 is slidably located in a bore 18 in the piston 13. The piston 13 has a rack gear 17 which meshes with a pinion 32 on a spindle 31 so that rotation of the spindle 31 moves the piston 13 in the cylinder 12. The cylinder 12 is attached to the door and the spindle 31 is attached to the door frame via a linkage arranged to rotate the spindle 31 as the door opens and closes. A non-return valve 19 allows hydraulic fluid to pass the piston 13 when it is moved against the spring 25 upon opening the door but when the spring 25 returns the piston 13 to close the door, the fluid is forced to return via a groove 29 in the rod 21, an eccentric groove 27 in the bore 18 and a conduit 28. Angular adjustment of the groove 29 with respect to the eccentric groove 27 varies the damping effect of the fluid on the return force of the spring 25. <IMAGE>

Patent GB-2139198-A (GB)
Title: Hopper level indicator
Inventor: JONES MALCOLM
IPC: B65D90/48
Filed: 1983-02-26
Abstract: An elongate arm 11 hangs down in and is surrounded by the contents of a hopper, for example animal feed or grain. The arm 11 is fixed to one end of a shaft 12 which pivots inside a tube 13 entering the hopper wall. Another elongate arm 16 is fixed to the other end of the shaft 12 and projects normally at right angles to the arm 11 when that arm 11 is in its downward-hanging position. As long as the level of the hopper contents stays above the bottom of the arm 11, the external arm 16 stays horizontal. When the level of contents falls below the bottom of the arm 11, a weight 24 hanging from the end of the arm 16 automatically pulls the arm 16 into a downward-hanging position to indicate to an observer that the hopper will need refilling fairly soon. <IMAGE>

Patent GB-2140215-A (GB)
Title: Extra low frequency underground wireless antenna
Inventor: HINE DAVID MICHAEL
IPC: H01Q9/00
Filed: 1983-04-26
Abstract: An antenna comprises bare metal elements buried in the earth. This antenna makes direct use of the role that the wet earth plays in the propagation of E.L.F. signals by conduction. The E.L.F. waves travel easily through the wet earth as a changing pressure gradient, the earth or sea being in effect the "medium" or an "aether" of almost perfect conductivity and extremely low impedance. This low impedance must therefore be met by the very intimate contact of a large amount of metal extending over a large area. <IMAGE>

Abstract: A method and apparatus disclosed in the invention are effective to carry out the (SSB) frequency multiplexing and demultiplexing of N base band sampled signals by purely digital processing. On the multiplexing path the apparatus comprises a time invariant single filter having a single input and only one output. At said unique filter input the N signals to be multiplexed are applied which are in form a single signal that is the time multiplexing of said N signals.   The signal at the filter output is sent to a successive modulator which is a multiplier having a time varying multiplying coefficient. The real samples of the modulator output signal provide the SSB frequency multiplexed signal of the N incoming signal paths.

Patent GB-2145866-A (GB)
Title: Method and apparatus for recording and replay of digital audio data
Inventor: MCNALLY GUY WILLIAM WITSEY
IPC: G11B27/10
Filed: 1983-08-26
Abstract: For both recording and replay, a digital audio tape (14) is accelerated very rapidly by a motor servo (9), motor (8) and capstan (7) so that the tape speed overshoots nominal speed range before settling back to this range in an oscillatory manner. The digital samples are recorded and replayed via a head (15), a random access memory (16) and input/output electronics (19). During recording, the store (17) is precharged by starting to write in as soon as acceleration is initiated. Read-out to the tape is initiated as soon as the tape first reaches the nominal speed range. Uniformity of samples as recorded on the tape is preserved by clocking a read address generator (21) at a rate proportional to tape speed, signaled by a tachometer (7). The write address generator is clocked at the constant sampling rate. For replay the write address generator is clocked at the tape speed rate while the read address generator (21) is clocked at the constant sample rate. Write in and read out are both initiated when the tape speed first reaches the nominal range. The addresses provided by the generators (20 and 21) are compared by a comparator (22) which provides a reference signal to the servo (9) in an arrangement such as to adjust the tape speed always in the sense to maintain a constant degree of filling of the store (17).

Patent GB-2169567-A (GB)
Title: Power assisted steering gear assembly
Inventor: DOWNING PHILIP ARTHUR
IPC: F16H19/00
Filed: 1985-01-11
Abstract: A power assisted steering gear assembly has a rack bar 1 which is biased at 7 through a bearing surface 9a for its teeth to engage a straight toothed pinion 5. The rack teeth 4 vary in pitch on a pitch line 13 with the teeth in a central region 10 having a pitch which is less than the teeth in each end region 11. The pitch line 13 and bearing surface 9a are profiled with respect to each other so that the biasing force exerted by 7 is greater when the pinion engages with the rack teeth 11 of larger pitch than when the pinion engages with the rack teeth 10 of smaller pitch. The variation in basing force may be achieved by smoothly recessing the bearing surface 9a over the longitudinal extent of the rack or by varying the effective height of the rack teeth to vary the pitch line of the rack relative to the bearing surface 9a. <IMAGE>

Title: Temperature responsive actuating elements
Inventor: PLACE DONALD EDWARD
IPC: G12B17/04
Filed: 1985-08-23
Abstract: A smooth top cooking unit comprises a glass top (14) and rapid response radiant heaters (17), such as tungsten halogen lamps. A temperature limiting control is connected to prevent excessive temperatures from occurring in such smooth glass top and provides a temperature sensing probe (19) extending across the unit between the heaters and the smooth top. Premature cycling of the heaters by the control is avoided by providing a heat shield along the probe which reduces the direct transmission of radiant heat from the lamps to the probe. In some embodiments illustrated, the shield is structured to reduce the sensitivity of the probe to radiant heat emanating from the heaters while increasing the sensitivity of the probe to radiant heat emanating from the smooth top. In other embodiments, the shield functions to reduce the sensitivity of the probe to radiant heat reaching the probe from all directions. <IMAGE>
