Patent GB-2278746-A (GB)
Title: A power controller for motors
Inventor: LEVESLEY PETER
IPC: H02P7/288
Filed: 1993-06-03
Abstract: A device to control the speed of induction or shaded-pole fractional horsepower electric motors, when driven by alternating current taken from a mains supply, by connecting the motor to the supply at each zero-crossing by a switch device 9 and breaking the connection part of the way through each half-cycle. To avoid abrupt voltage changes that would otherwise give rise to vibration and Radio Frequency Interference, a capacitor 11, wired in parallel with the motor, discharges its stored energy into the motor after the supply connection is broken. An example of a complete power controller incorporating this principle is shown, together with control circuit 63 - 65 and zero crossing detector 41, 50, 52 to control the duration of the conduction period and hence the power delivered to the motor. Also shown is the circuitry 14, 73 - 77 required to protect the switch device 9 under fault conditions. <IMAGE>

Abstract: A gain control circuit (500) for a radio transmitter (780), such as the radio transmitter portion of a radiotelephone (780) operative to transmit a  pi /4 DQPSK-modulated signal in discrete bursts. The signal portion of the signal transmitted during each discrete burst forms a slot and at least one of the slots includes a predetermined data sequence portion (300). The peak power level of the portion of the slot comprising the predetermined data sequence portion, once amplified by amplifier circuitry (512) of the radiotelephone (780), is measured by measuring apparatus (546) is compared with a stored value representative of the peak power level of a corresponding portion of a slot amplified to be of a desired signal level. Responsive to such comparison, the amplification level of the amplifier circuitry (512) is altered. <IMAGE>

Patent GB-2285516-A (GB)
Title: Quiescent current testing of dynamic logic systems
Inventor: MILLER JNR ROBERT H
IPC: H01L21/66
Filed: 1994-12-21
Abstract: Nodes shorted to ground are detected during a dynamic pre-charge state. Nodes shorted to a power supply potential are detected by driving all nodes of interest to ground during a dynamic evaluation phase. Nodes are driven to ground directly by one additional transistor 116, per node or indirectly by logical propagation from upstream nodes. Thus, only two current measurements are needed for all shorted node faults, even for pipelined systems with multiple clocks. There is no need for input test signal sequences or signal propagation to outputs for detection. Specific embodiments are provided for single-rail logic (figure 1B), single-rail pipelined systems, dual-rail logic and dual-rail pipelined systems. For single-rail pipelined systems, optional transistors between stages (328, 330, 332 Figure 3B) enable preservation of logical states during testing. For dual-rail logic, storage nodes and static nodes are forced to a logical state that is not possible during normal operation. For pipelined dual-rail logic, testing of alternate stages inherently preserves the logical state of the system during testing. <IMAGE>

Patent GB-2299039-A (GB)
Title: Injection molding apparatus
Inventor: KAZAMA SHINJI
IPC: B22D17/30
Filed: 1996-03-22
Abstract: A receiving chamber receives a material heated in a heating chamber. An injecting shaft 48 of an injecting machine slurries the material crushed by cutters 33 downstream of the receiving chamber and feeds the slurried material to an injection port 44c formed between the fore ends of the shaft and injecting chamber so that the slurried material is gradually accumulated in the port. The shaft is retracted by counteraction from the slurried material accumulated in the port, over a distance proportional to a current accumulated amount of the material in the port. The current accumulated amount of the material in the port can be detected from a current position of the shaft, and then it is determined whether the detected current accumulated amount has reached a predetermined amount. When the current accumulated amount has not reached the predetermined amount, the cutters and injecting shaft are further driven until the predetermined amount is reached. The receiving chambers 28 may have passage sections 74 on its outer surface in opposed relation to each other, which function both as light beam passages for light emitting and receiving elements 92a, 92b (photosensors) that are provid d on the sections for detecting whether a heated material is in the receiving chamber, and as inert gas supply passages to direct inert gas into the receiving chamber.

Title: Fluid flow control valve
Inventor: SCARFFE MICHAEL FREDERICK
IPC: B67D1/00
Filed: 1993-07-27
Abstract: In a system for dispensing mixed beverages a processor controls the liquid dispensed at an outlet in dependence upon the demand of a user as input to a keypad. Carbonated water is fed to the outlet and a syrup concentrate is also fed thereto. The water and syrup is mixed in the correct quantities by way of respective pilot chamber proportional valves which adjust the quantity or flow rate of the two constituents fed through a mixing chamber in accordance with flow rate readings provided to the processor by respective flow transducers. The flow transducers measure the speed of flow ultrasonically and are able to provide flow rate readings at a rate of 50 per second. The proportional valves are able to adjust the quantities fed to the mixing chamber at a similar rate such that the mix can be reliably determined even if there are transitory pressure drops or viscosity changes in the system.

Title: Friction welding sheet material
Inventor: THOMAS WAYNE MORRIS
IPC: B23K20/12
Filed: 1996-12-06
Abstract: A method of friction welding suitable for joining workpieces and forming a joint region therebetween comprises the steps of:-  (i) Offering a probe 1 of material harder than the workpiece material to the workpiece surfaces in the joint region, a head region of the probe contacting one or both workpieces; (ii) Causing a rotational movement between the probe and the workpieces while urging the probe and workpieces together whereby frictional heat is generated in the joint region so as to create a plasticised region in the workpieces around the probe; (iii) Removing the probe or advancing the probe along the joint region and allowing the plasticised region to solidify and thereby join the workpieces together.  The method is characterised in that the head region of the probe incorporates a plurality of protrusions 2 adapted to penetrate the workpieces. Such protrusions 11 may be crescent shaped.

Title: Method of and apparatus for pilot channel acquisition
Inventor: STORM BRIAN D
IPC: H04B1/7117
Filed: 1997-08-18
Abstract: A wireless communication device 100 acquires a pilot channel before an assigned slot when the wireless communication device is operating in the slotted mode of a CDMA system. The wireless communication device comprises a searcher receiver 109 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.

Title: Method of controling a mechanical supercharger driven by an i.c. engine via a differential gear
Inventor: OZAWA GODOU
IPC: F16H47/04
Filed: 1995-01-20
Abstract: The mechanical supercharger 20 is driven via a planetary differential gear 10, with the engine 1 driving the plant carrier 13, the supercharger 20 being driven from the sun gear 11 and an external input, eg a variable hydraulic motor 30, controlling the speed of the ring gear 14.
