Patent GB-2092089-A (GB)
Title: Handling bales of materials
IPC: A01D90/08
Filed: 1980-11-19
Abstract: In an agricultural vehicle, an apparatus for automatically loading bales (5) of material forms successive rows of aligned bales (6, 7, 8) and lifts each row as a unit to form a stack of such rows to a height of N<2> bales. The stack is then shifted the width of a bale away from the location of the stacking operation and the bale- aligning and row-stacking process is repeated until another stack is formed adjacent the first. The process may be continued until the vehicle is full. The apparatus can perform an unloading operation in which the top row of a stack is removed and discharged from the vehicle followed by the sequential removal from the top of all rows ill the stack. The remaining stacks in the vehicle are transported the width of a bale toward the removing station and the operation is continued until all the bales are discharged. The operation is preferably controlled by a digital processor. <IMAGE>

Patent GB-2071934-A (GB)
Title: Changing the frequency of a power supply
IPC: H02M5/27
Filed: 1981-03-04
Abstract: The frequency of a power supply signal is changed by continuous modulation of each phase of the supply voltage, combining of the modulated signals if there is more than one phase and further processing to produce a supply signal of a single frequency. As shown, the modulated signal is rectified and the rectified signal is inverted to produce the signal of single frequency. In an alternative arrangement, the supply signal is rectified before being modulated. The modulation waveform may be sinusoidal or triangular to provide amplitude modulation. <IMAGE>

Title: Lampholders
IPC: H01R33/46
Filed: 1981-03-26
Abstract: A lampholder has an inner body part (12) with upstanding portions (20, 21) to house lamp contact parts (31, 32) and wire connectors (36, 37). The upstanding portions (20, 21) are open at their sides (eg 25) to allow ready insertion of lamp contact and wire connector parts prior to assembly with an outer body part (10). On assembly, the outer body wall parts (27, 28) close the upstanding portions (20, 21). The wire connectors advantageously engage with interiors of the upstanding portions against axial displacement and serve as seats for springs (34, 35). A further, loop-in, wire connector (52 see figure 3, not shown) may be provided. Flangings (13, 14 figure 2, not shown) of the body parts may sandwich flanging of a metal lamp carrying liner (15) to secure the latter in place. Depending side walls (66, 67) of the outer body part assure against tracking (i.e. current flashover) between the liner (15) and the contents of the upstanding portions. <IMAGE>

Title: Improvements in or relatig to stepping motor driven analog timepieces
IPC: G04C3/14
Filed: 1978-11-28
Abstract: A driver circuit for a stepping motor having a coil, a stator and a rotor receives pulse signals from a pulse signal generator to rotationally drive the rotor. A rotation detection circuit comprises switching circuitry switchable between a high impedance loop formed of the coil and a high impedance element and a low impedance loop formed of the coil and a low impedance element, and means for detecting the voltage induced in the coil. After a pulse signal is applied to the stepping motor, the switching circuitry forms the high impedance loop and the detecting means compares the voltage developed across the high impedance element with a predetermined voltage to thereby detect the rotation and non-rotation states of the rotor. This is a divisional of application Ser. No. 966,115, filed Dec. 4, 1978, now U.S. Pat. No. 4,326,278.

Title: Beer dispensing tap
Inventor: BOYES ADRIAN PHILIP
IPC: B67D1/14
Filed: 1982-10-22
Abstract: A beer dispensing tap has a valve member 2 which is biassed closed by a spring 7 and engages a valve seat 19 on an annular piston 18 held by the member against the bottom of a chamber 5 surrounding the entrance to an outlet spout 16. When the tap is opened by rocking the handle 11, the valve member 2 is initially lifted from the seat 19 to allow beer to flow smoothly and without frothing from the inlet 15 through the chamber 5 and the outlet spout 16, following which the piston 18 is then lifted with the member 2, by means of a lost motion coupling 27 to 29, to create a small reservoir chamber 30 below the piston which fills with beer via passages 26 and which is isolated from the spout 16 by a tubular extension 20 projecting into the spout. When the tap is closed, the spring 7 first moves the valve member 2 to engage the seat 19 to shut off the beer flow, and then to drive the piston 18 to expel the beer from the reservoir 30 through a small outlet 31 as a high velocity jet which is directed into the beer just dispensed to thereby create a head. <IMAGE>
Patent GB-2110570-A (GB)
Title: A method of protecting a catalyst in the exhaust-gas flow of an Otto-type engine against contamination by pollutant particle deposits
Inventor: ABTHOFF JORG
IPC: F01N13/02
Filed: 1982-10-26
Abstract: The protection of a catalyst in the exhaust-gas flow of an Otto-type engine by electrostatic precipitation of pollutant particles is limited in effectiveness because in the course of operation the precipitation surfaces are soon overloaded. By effecting electrostatic precipitation only at exhaust-gas temperatures at which the pollutant particles have a harmful effect on the catalyst, preferably, not below a temperature of approximately 200 DEG C, the precipitation surfaces can be blown clear when precipitation is not taking place and the apparatus can remain constantly effective. The cleaning of the precipitation surfaces can be assisted by reversing the polarity of the system.
