Patent GB-2068461-A (GB)
Title: Regenerative turbo machines
IPC: F04D23/00
Filed: 1980-02-01
Abstract: The machine is provided with one or more breather passages 17 in a stripper 16 which separates the inlet port 14 and outlet port 15 of the toroidal channel 13 in which the vanes or blades 12 of its rotor 11 rotate. Fluid trapped between the vanes and carried into the stripper is bled therefrom and the passage or passages are shaped and disposed to direct such fluid to escape in a path or paths which will induce or enhance flow through the inlet port. Fluid from the stripper may be injected into the inlet port along its walls in the direction of inflow to provide a venturi effect and reduce turbulence, and/or it may be led into the inlet end of the toroidal channel 13 in a region of the channel on the side of the rotor remote from the inlet port. <IMAGE>

Title: Regulating the cross-section of the fiber roving delivered by a drawing machine
IPC: D01H5/42
Filed: 1980-09-25
Abstract: The drawing rollers (3) and the small rollers (5) for guiding the roving delivered by a textile fiber drawing machine are driven by a main shaft (5a). The feeding rollers (1) are driven from the same shaft through a differential mechanism (14) coupled to an auxiliary motor (30) which is controlled by an electronic speed- changing unit (29). This unit is responsive to the difference between voltages delivered respectively by a tacho-dynamo (31) which is driven by the auxiliary motor and by an electronic memory (28) placed at the output of a strain-gauge bridge (27). The bridge is influenced by strain gauges (26) fixed on resilient feeler blades (25) which are applied against the fiber slivers (2a, 2b, 2c, 2d) by means of wheels (23, 24). Any increase in sliver thickness sensed by the strain gauges produces a reduction in speed of the feeding rollers and a corresponding increase in the degree of draft. Conversely, a reduction in sliver thickness has the effect of increasing the roller speed and reducing the degree of draft. <IMAGE>

Title: Digital relay
IPC: H02H3/05
Filed: 1981-06-12
Abstract: In a digital relay, the circuit for repetitively obtaining a digital measure of the amplitude I of an analogue current or voltage, I sincwt say, includes a self-checking feature to ensure that a correct measure of I is furnished despite errors in the sampling or computation processes. From the most-recent digitised samples of the input two or more separate computations of I are made (21, 22), either (i) using odd- numbered samples, say, for one computation and even-numbered samples for the other, or (ii) using the same samples for both but with different algorithms. The two computations are compared (3) and an output Y representing them supplied so long as they agree. If they disagree, the two present computations of I are compared (61, 62) with previous ones (4, 5) to identify which computation is wrong and furnish the correct one to the output Y. Three possible algorithms for the computations are disclosed. <IMAGE>

Patent GB-2122726-A (GB)
Title: Gas container valve assembly
Inventor: BARSKI RICHARD JOHN
IPC: F16K17/16
Filed: 1982-07-01
Abstract: An excess-pressure release device comprises a burstable disc (15) and a plunger (22, 23) displaceable by gas pressure after the disc has burst to allow gas to escape through a preferably downwardly-directed gas outlet (12). The bore (18) in which the plunger moves is stepped and the plunger has portions (24) resiliently biased outwardly which engage the shoulder (27) of the stepped part of the bore when the plunger is displaced by gas escaping through the burst disc. This prevents the indicator (23) on the plunger from being accidently re-set, giving a false indication after the gas has been released. The plunger can be provided with a spike to enable the disc to be burst manually to release the gas when, for example, the valve has jammed. <IMAGE>

Patent GB-2108796-A (GB)
Title: A constant current source circuit
Inventor: OGAWA ATSUSHI
IPC: G05F3/30
Filed: 1982-10-11
Abstract: A constant current source circuit producing a relatively stable constant current is disclosed. A first transistor and a second diode-fashioned transistor (32, 34) have their base- emitter circuits coupled in parallel. One of the transistors (34) has an effective base-emitter junction area greater than that of the other and has a current determining resistor (38) in its emitter current path. A differential amplifier (48) detects a collector potential of the first transistor for producing a first current (I42) varying in inverse proportion to the collector potential. First and second means (64, 66) are connected for supplying a second current (I64) and a third current (I66) to the first and the second transistors respectively. The second and the third currents are controlled by third means (62) to vary in proportion to the first current, this negative feedback by the Differential Amplifier stabilizes Iout against changes in Vcc. This arrangement also improves startup. <IMAGE>
