Title: Control of fuel supply in internal combustion engines
IPC: F02M41/14
Filed: 1981-08-21
Abstract: A fuel system for an internal combustion engine includes an electromagnetic means 52 which when energized causes an increase in the amount of fuel supplied by a fuel pump forming part of the system, to an associated engine. A transducer 54 which provides a series of signals at predetermined positions of a rotary part of the engine, is provided, the signals being supplied through a shaping circuit 55 to a delay circuit 56 which provides a signal of fixed time length to a second circuit 58 to de- energise the means 52 every time a transducer signal is moved. As the engine speed increases therefore the amount of fuel supplied by the pump decreases and vice versa. The delay circuit is adjustable by the engine operator so that he can exercise some control over the quantity of fuel supplied by the pump. A third circuit 57 provides a continuous signal to de-energise the means 52 if the interval between pulses from transducer 54 becomes excessive. <IMAGE>

Patent GB-2093473-A (GB)
Title: Elastomeric Bladders for Medical Infusers
IPC: A61L31/00
Filed: 1982-01-08
Abstract: Elastomeric bladders having improved resistance to spontaneous rupture when inflated are made by vulcanizing a homogeneous mixture of synthetic polyisoprene having 90% to 98% cis-1,4 linkages, finely divided silicon dioxide or carbon black, and vulcanizing agent while simultaneously forming the mixture into hollow tubular bodies. After being formed the bodies are solvent extracted to remove unreacted vulcanizing agent and the degradation products of the vulcanizing agent. Following the solvent extraction a nontoxic, nonleachable antioxidant is imbibed into the bodies by contacting the bodies with a liquid solution of the antioxidant.
Patent GB-2091585-A (GB)
Title: Process and apparatus for concentrating juices
IPC: A23L2/10
Filed: 1982-01-20
Abstract: In current practice, fruit and vegetable juices are normally clarified by filtration and/or centrifuging. In addition it is frequently necessary to remove pectin by an enzymatic process. In accordance with the invention, the juice is subjected to a process of ultra-filtration (6) to achieve clarification and depectinization. The juice may be dosed with an enzyme for depectinisation. The juice is then fed to an evaporator (10) to be concentrated. If a cloudy concentrate is required, a controlled proportion of the retentate (9) from the ultra- filtration may be added (22) to the concentrate. The ultra-filtration is preferably carried out prior to aroma stripping, which may take place in a second effect (10) of a multi-effect evaporator (10, 13, 15) in which the juice is concentrated and to which the permeate from the ultra-filtration is fed. <IMAGE>

Title: Measuring the weight of powder feed
Inventor: MIZOKAWA TAKUMI
IPC: G01G11/14
Filed: 1982-08-20
Abstract: A powder control system has a pressurised powder feed container 4 for supplying powder from delivery port 7. The feed container 4 is connected to a replenishing container 3 by an expansible joint 5. Containers 3 and 4 are supported by load cells 6 and 8, signals from which are compensated for variations attributable to the pressurisation of the feed container 4, and displacements of expansible joint 5. The total weight of powder fed in any given period of time is determined by adding the weights of each replenishment from the replenishing container 3 to the feed container 4, and subtracting the weight of powder in containers 3 and 4 from the total weight of powder replenishment when the measurement is made during a replenishing operation, or subtracting the weight of powder in feed container 4 from the total weight of powder replenishment when the measurement is made outside the period of a replenishing operation. <IMAGE>

Patent GB-2138635-A (GB)
Title: Metal Enclosed Switchgear
Inventor: YAMAMOTO TOSHITARO
IPC: H02B11/00
Filed: 1984-04-18
Abstract: Metal enclosed switchgear includes a box (2) with a bottom (2a), a circuit breaker assembly (8) being freely carried into or out of the box (2) on rollers (9) rolling on the bottom (2a), an earthing switch (18), a rod (23) for operating the switch (18) and a mechanical interlock (A) between the breaker (8) and the switch (18). The interlock (A) includes a roller stopper operating rod (29) rigidly secured to the earth switch operating rod (23), a movable roller stopper (35) operated by the roller stopper operating rod (29) to be rotated extending into a path on the bottom (2a) of a roller (9) and a stationary roller stopper (36) rigidly secured to the bottom (2a) to contact against the movable roller stopper (35). Thus, an impact which is effected by an inertia in carrying-in of the breaker (8) can barely destroy the interlock (A). Additionally, since the interlock (A) consists of mechanical elements alone, a part of the interlock (A) which is disordered or destroyed is apparent and ready to repair.   <IMAGE>
Patent GB-2157921-A (GB)
Title: Multiplexer/demultiplexer
Inventor: COHEN MORDECHAY
IPC: H04J3/16
Filed: 1984-04-19
Abstract: In order to multiplex a plurality of bit streams having a plurality of bit rates which are not necessarily whole number multiples of each other, each bit in each input stream is sampled once only. A logic circuit (7) causes a sampler (2) to sample the input bit streams (1) according to a predetermined sequence of four bit binary codes which are fed to the sampler. A counter (5) clocked at the multiplexed bit rate, counts up to a predetermined number there being a binary code for each count, so that the number of sampled bits in a frame corresponds to this predetermined number. To demultiplex the multiplexed bit stream, it is passed through a variable length shift register to switching means which switches the input stream between a plurality of output streams according to the predetermined sequence of four bit binary codes. In order to be able to use the same predetermined sequence of codes, the frames of the input bit stream to the demultiplexer must be synchronised with the frames of the output bit stream from the multiplexer and this is achieved by adjusting the length of the variable length shift register. <IMAGE>
