Abstract: 1,141,292. Two-stroke engines. J. L. SCOTTSCOTT. Feb.28, 1966 [Dec. 1, 1964], No.48691/64. Heading F1B. During part- and no-load engine operation, some of the gases in the cylinder pass through passages 10, 14, 22 and 23 either to atmosphere or, via a flame trap, to the crank-case. Passage 10 can be closed by rotating an externally threaded tube 16 (by means of an arm 17) whereby aresiliently mounted stop 18 urges a ball valve 12 on to its seating 11. When tube 16 is rotated in the opposite direction, pressure in the clearance volume moves the ball valve off its seat 11 until it abuts stop 18, the position of which is adjustable. Passage 10 may be provided in the cylinder head or the cylinder wall adjacent the head or, as shown, in a piston 15, the axial position of which may be manually adjusted (by means of arm 7 and an externally threaded tube 6) to vary the compression ratio. The valve 12 may be operated by remote (e.g. radio) control instead of manually. A nut 24 and spring 25 prevent tube 16 from rotating loosely out of an adjusted position.

Abstract: 1,271,058. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORP. 28 Oct., 1970 [14 Nov., 1969], No. 51103/70. Heading H3T. [Also in Division G4] A circuit for rejecting unwanted "shoulder noise" from binary signals comprises: two channels A, B, receiving complementary data signals, each channel comprising a gate 106, 106<SP>1</SP> connected to the channel input 104, 104<SP>1</SP> through a first path including an inverter 116, 116<SP>1</SP> and a second path including a delay 118, 118<SP>1</SP> the arrangement being such that the gate of one channel is open during a timed interval following each data signal transition of one polarity, and the gate of the other channel is open during a timed interval following each data signal transition of the opposite polarity, the durations of the timed intervals being such as to inhibit the shoulder noise signals; and means 102 for combining the outputs from the two channels. In a first embodiment, Fig. 4, a magnetic recording head provides input signals, Figs. 5A, 5H, with shoulder noise pulses 144, 146, 148, 150, which are applied to the two channels. The channel A input is fed through inverter 116 and delay units 118, 120 having delay times T2, T1 to provide three inputs, Figs. 5B, 5C, 5D, for AND gate 106. The AND output, Fig. 5E, is fed to one input of a NAND gate 170 which is enabled for a period following each negative transition of the input signal 132, 134, 136. The gate is then inhibited by monostable 172 for a period T3 to prevent transmission of the shoulder noise pulses. Channel B functions in a similar manner in respect of the other data signal transitions, and the two noise-free output signals, Figs. 5G, 5N, are combined in NOR gate 102 to produce the required output, Fig. 50. In a second embodiment, Figs. 6, 7 (not shown), the AND and NAND gates are replaced by a single NAND (190, 190<SP>1</SP>) the inhibit signals for which are derived from monostables (208, 208<SP>1</SP>) triggered by signals from the other channel and the time period T2 is provided by a monostable (204).

Abstract: 1282613 Rotary positive-displacement machines E PRITCHARD 27 Oct 1969 [28 Oct 1968] 52543/69 Heading F1F A motor driven by a compressible fluid such as steam or air has a rotary structure 4 attached to an output shaft 21 and furnished with sealing segments 4a that engage with blades 3 supported by a fixed shaft 2. A proportion of the fluid in a supply line 6a is diverted through a flow-restricting passage 8 and a passage 9 into one of the interblade chambers 5 between an inlet port 6 and an outlet port 7. When it is necessary to augment the torque at the shaft 21 e.g. on starting, the flow through the passage 9 is increased by a valve 11 opening to connect a passage 10 to a passage 15, this being due to a greater pressure-differential occurring between the line 6a and a passage 13 and consequent deflection of a spring-loaded diaphragm 12. The effect produced by the increased flow through the passage 9 is comparable to that of "late cut-off" in a conventional reciprocating steam-engine. Alternatively, the valve may be such that it opens in response to a rise in the pressure in the line 6a, (For Figures see next page)
