Patent GB-2012394-A (GB)
Title: Valve for Sensitive Fluids
IPC: F16K41/10
Filed: 1979-01-15
Abstract: A valve for controlling the flow of a sensitive or explosive fluid such as nitroglycerine, likely to cause contamination, has a bellows (19) or a diaphragm attached to the valve housing and to the spindle 6 or the valve closure member 7 so as to define a chamber 20 which is filled with a desensitising fluid, the valve being provided with means to detect any leakage of the sensitive fluid into the chamber 20. The detection means consists of a pressure sensing device for indicating changes in the pressure of the desensitising fluid, for example a U-tube manometer with liquid level detectors beyond its normal range of operation. In a preferred embodiment the movement of the valve is damped by the restricted flow of the desensitising fluid through small bore channels (21, 21'). In this way safe operation is guaranteed under normal conditions and safeguards are provided to protect against and warn of any breakdown. <IMAGE>

Title: Fuel pump control mechanism
IPC: B60R25/042
Filed: 1979-03-19
Abstract: A fuel pump (48) for a diesel engine has a control lever (49) movable from "cut-off", through "idle", to "maximum". An accelerator mechanism has a first part (42,22) movable with an accelerator pedal between "idle" and "maximum", and a second part (23,24,50) movable with the control lever (49) and urged by a spring (29) to follow the first part from "idle" to "maximum". A further mechanism has a "cut-off" position in which it holds the second part (24) in the "cut-off" position irrespective of movement of the accelerator, and a "running" position in which it permits the second part to follow the movement of the accelerator. To provide such action, the further mechanism comprises a bowden cable mechanism, a boss (52) on the second part sliding along an end portion (54) of the inner cable when in the "running" position and being held by a nipple (55) on the end of the inner cable when in the "cut-off" position. The inner cable is operated by a reversible electric motor (61) connected to a switch (62), Fig. 5 (not shown), associated with a vehicle steering column lock. An idling stop (18) is abutted by a lever (13), engaged by the lever (23), in the idling position of the accelerator pedal. <IMAGE>

Title: Electronic timepiece
IPC: G04G99/00
Filed: 1979-08-15
Abstract: An electronic timepiece gives upon demand, an audible tactile or optical indication of current "strokes" corresponding to the strokes of a mechanical clock, e.g. each hour stroke may comprise dual tones.

The signalling device may also be used to give the alarm in response to an output from coincidence detector 37. The timepiece may additionally incorporate a conventional analogue or digital time display. <IMAGE>
Patent GB-2030848-A (GB)
Title: Food processing apparatus
IPC: A23L7/109
Filed: 1979-08-21
Abstract: Production of a desired number of individual cut food stuff strips by feeding a predetermined number of continuous lengths of food stuff strips 1 to a cutter means 2 which cuts said strips and concurrently and automatically counts the number of cutting operations by a counter 8 incorporated therewith. Containers 3 are successively arranged under the cutter means at a predetermined speed or at predetermined intervals. The counter 8 is connected, through a reference signal circuit, either to an actuator 17 of a transfer means 7 which transfers the containers or to a shutter means 14 which shuts or opens the passage between the cutter means and the container, thereby the transfer means moves the container under the cutter means to a next position or the shutter is opened and then closed prior to the movement of the container, when the counter means has finished a predetermined number of cutting actions. According to the above-mentioned mode of operation, the number and quantity of the food stuff strips of long and thin noodle like material to be received by each container can be predetermined and detected in a very accurate and effective manner. <IMAGE>

Patent GB-2037037-A (GB)
Title: Data-processing apparatus
IPC: G06F12/0855
Filed: 1979-11-02
Abstract: A data processing system comprises a data processing unit coupled to a cache unit r which couples to a main store. The cache unit (Fig. 4 not shown) includes a cache store (750-300) organized into a plurality of levels, each for storing blocks of information in the form of data and instructions. The cache unit further includes control apparatus, (750-5) an instruction buffer (750-7) for storing instructions received from main store and a transit block buffer (750-102) comprising a plurality of locations for storing read commands. The control apparatus includes a plurality of groups of bit storage elements corresponding to the number of transit buffer locations. Each group includes at least a pair of instruction fetch indicator elements which are operatively connected to control the writing of first and second blocks of instructions into the instruction buffer. Each time a read command specifying the fetching of instructions of either a first or second block is received from the processing unit, the flag storage element associated with the transit block buffer location into which the read command is loaded is set to a binary ONE state while the corresponding ones of the flag storage elements associated with the other locations storing outstanding read commands specifying instruction fetches are reset to binary ZEROS. This permits only those instructions received from main store in response to that read command to be loaded into a specified section of the instruction buffer for enabling overlaps in processing several commands specifying instruction fetch operations. The instruction buffer has first and second sections (750-715, 750-717) for storing instructions received from main store. Each instruction buffer section includes a plurality of word storage locations, each location having a number of bit positions. A predetermined bit position of each location is used to indicate when an instruction word has been written into the location. Control apparatus coupled to each of the buffer sections is operative to reset all of the word locations to binary ZEROS when a command requesting an instruction block from main store is ready to be transferred thereto. It is set to a binary ONE state when an instruction word is loaded into the location. Instruction buffer ready circuits included within the control apparatus are conditioned by the states of the predetermined bit positions of the locations to generate output signals to the processing unit enabling the transfer of requested instruction words to the processing unit as soon as they are received from main store.

Title: Axial-flow rotary compressor
IPC: F01D1/12
Filed: 1981-03-16
Abstract: The compressor has a fluid flow inlet 12 circumferentially separated from a fluid flow outlet 20 by a dynamic flow splitter 18 comprising at least one toroidal chamber providing a loop fluid flow path 24 intersecting the path of the rotor blades 2 such that any fluid leakage through the flow splitter flows around the loop flow path 24. Regeneration of the flow through the rotor blades 2 as they emerge from the flow splitter 18 is thus facilitated. The flow splitter 18 may comprise a number of contiguous chambers (27-31), Fig. 4 (not shown), whose apertures can increase towards the low pressure end of the flow splitter to compensate for the decreased density of the fluid. The downstream walls of the flow splitter chambers can be offset relative to the upstream walls so as to provide a direct quasi-helical fluid flow path through the flow splitter to increase the enthalpy transport through the flow splitter. <IMAGE>

Title: Stabilization Slurries of Issolefin Polymers
IPC: C08F210/10
Filed: 1982-02-22
Abstract: Polymerization slurries of elastomeric isoolefin homopolymers and copolymers, such as butyl rubber, in diluents such as methyl chloride are effectively stabilized against agglomeration of polymer particles through addition of minor proportions of (i) a preformed copolymer stabilizer having both a lyophobic or lyophilic portion, or (ii) an in situ formed stabilizer from a functional lyophilic stabilizer precursor capable of copolymerizing or otherwise chemically bonding with the polymer product. Agglomeration of polymer products is effectively prevented, yielding a number of significant processing advantages. The process is especially adaptable to the production of isobutylene-isoprene butyl rubber.
