Patent GB-2203195-A (GB)
Title: Circuit for operating a fluid-pressure driven piston
Inventor: STOLL KURT
IPC: B23K11/31
Filed: 1988-02-29
Abstract: The invention provides an operating device for a piston (11) running in a double-acting cylinder (10), whose piston rod (12) in the form of a tool or functional member is able to be brought into engagement with a workpiece (27) by being driven by pressure in chamber (14). Before the piston rod reaches the position of engagement on the work a position sensor (26) sends signal EO to electronic controller (24) which causes valve (23) to close so that chamber (15) must be drained through choke (21) which thus causes the piston to be retarded. A switch (28) detects the position of engagement by the change in pressure in at least one of the two cylinder chambers (13 and 14), and sends signal E1 which causes valve (23) to be opened again increasing the thrust on workpiece (27) so that welding etc can be performed. After a preset time, controller (24) returns valves (20) and (23) to the position shown, whereupon the higher pressure produced by proportional regulating valve (19) over that of valve (18) causes the piston to be rapidly retracted to sensor (26) so that the whole cycle is repeated, up to a preset number of cycles. In another embodiment, chamber (13) may be rapidly discharged through two chokes, or slowly through one. Further, controller (24) operates a fluid-pressure clamp, holding the rod for a predetermined time in the engagement position. <IMAGE>

Title: Automatic signal parameter control
Inventor: FRY DAVID WILLIAM
IPC: H03G7/00
Filed: 1990-01-11
Abstract: A fast acting automatic gain control system comprising a single or serial multistage arrangement. In one multistage embodiment (Fig 1) each stage (13) has a first state with a predetermined gain and a second state with unity gain. The output of each stage determines what state is finally adopted although initially when a signal is input it is in the first state due to the action of a sequence controller (14). The predetermined gain values may comprise a binary sequence which descends in the direction towards the output. If the level detector (7) threshold is exceeded, the stage is set to the second state. A particular use of the system is to ensure burst mode pulses reaching a receiver are of similar amplitude. A similar method can be employed for phase alignment rather than gain control. In another multistage embodiment (Fig 2) a sequence controller is not required and the input signal level is used to set the required state of an amplifier (17) before the input signal is applied to the amplifier, by means of a comparator (15) and a delay (16). An analogue equivalent of the Fig 2 embodiment (Fig 3) is a single stage arrangement. <IMAGE>

IPC: B60B39/12
Filed: 1990-03-02
Abstract: A system to enable vehicles to escape entrapment by snow and ice, comprises two snow runs 6 for fitting close up to the driven wheels of the vehicle, connected to a drag weight 8 by cables 1 each passing through a ring 7 fixed to the underside of the vehicle. In use the vehicle is driven onto the runs 6 and when it moves off the other ends the drag weight 8 brings the runs inwardly under the vehicle clear of the wheels. The system can be used as many times as necessary to effect an escape by replacement of the components, and then be dismantled when the escape effected. It can be applied to both front and rear wheel drive vehicles. <IMAGE>

Abstract: 914,907. Coffee-making apparatus. THERMA A.G. Dec. 22, 1959 [Dec. 22, 1958], No. 43440/59. Class 129 A closed hot-water vessel 5 with a small opening 16 to the exterior above the highest water level therein delivers hot water through a tube 15 leading from its deepest point above the highest water level and then to a filter vessel 2 containing a float 12 co-operating with tube 15 to regulate the liquid level in vessel 2. As shown, a ceramic coffee pot 1 supports ceramic filter vessel 2 in which ground coffee is held in a paper filter 3. The vessel 5, having a lid 7 held by a clasp 8 rests on filter vessel 2 and the water therein is heated by a spiral 11 whose current supply is controlled by handle 10. When the water in vessel 5 boils, it is discharged through tube 15 until vessel 2 is full of water, when a valve pin 14 carried on ribs 13 on float 12 closes the lower end of tube 15. As the coffee beverage runs out of the filter vessel the float drops and more water runs through. Float 12 is connected at 17 to vessel 5.
