C. engine with twin rotors 54, 56 on a common output shaft 42 has intake ports 90, 92 in a housing member 30 and a common intake pipe 94 furnished with an air cleaner 96 and fuel injector 100, the effective areas of the said ports being variable so as to regulate the power output by a fork-shaped slidable-member 116 comprising arms 118, 120 and controlled by a pedal 132. The arms slide between parallel edges 110, 111 of portions of the intake ports that are extensions of the normal intake ports (indicated by a cross-hatched area in Fig. 2). Reduction of the effective areas of the intake ports (by depressing the pedal) increases the power output. When said areas are greatest some of the fuel-air mixture undergoing compression is spilt through the intake ports into the adjacent working chambers in which the induction phases of the working cycles are being performed; and this is said to improve the thermal efficiency. Ignition is effected by spark plugs 104, 105 and exhaust through ports 106, 108.

Title: Channel selection apparatus including a tuning element
IPC: H04N5/44
Filed: 1976-01-26
Abstract: 1485740 Channel tuning arrangements MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 26 Jan 1976 [6 Feb 1975] 02924/76 Heading H3Q In a channel selection apparatus at memory addresses of a memory 1 are stored digital voltages of channel selection voltage at 15 and channel skip control signals at 16 such that on addressing the memory 1 by address circuits 2-5 the selected channel voltage is read-out of the memory and via a D/A converter 17 tunes a voltage dependent variable reactance of a tuner 18 to the selected channel; however if a channel skip control signal is also read-out of the memory a skipping pulse generator 14 steps the addressing circuits 4, 5 by one. This continues until no channel skip control signal is read-out from the memory whereon the next required digital channel voltage is read-out from the memory. Switch 8 or 11 is closed to obtain the next channel address. As the memory 1 is programmable to stop address counters 4 and 5 only at selected channels and to skip unrequired channel numbers normal operation of the channel selector switch 8 or 11 channel by channel is avoided. On turn on of the power supply a capacitor (48, Fig. 5, not shown), resistor (46) and a transistor (45) resets the X and Y addressing counters 4, 5 to provide the CH1 address. The memory elements of 1 can be transistor bi-stable circuits (Fig. 4, not shown), magnetic cores or MNOS transistors and preferably non-volatile memory elements which retain their contents even when their power supply is turned off. Presetting the memory storage elements with the digital channel selection voltage and the skip control voltage. For CHl address the counter 24 adjusts the tuning voltage applied to the tuner 18 by the D/A converter 17 (Fig. 8, not shown) until stopped by reception of both the IF and horizontal synchronizing signal by a circuit 22. Then a switch 26 is moved from a non-write position 26b to a write position 26a so as to read the digital channel voltage output of the counter 24 via write gate 25 into the addressed memory element. If that channel is required to be skipped then a switch (57m, Fig. 9, not shown) of the write gate 25 is set to read a channel skip signal into the memory element in part 16 of the memory 1. Then the next memory element is addressed by the X and Y address counters 4, 5 and the counter 24 is again started until the next channel is received so that it may be written into the memory if required.  Waveband switching is obtained by a band selection circuit 30 (Fig. 12, not shown) controlled by a decoder 28 (Fig. 10, not shown) which provide coil switching of lower and higher VHF channels and power supply switching to the VHF and UHF tuners at 18. Channel indication 29 is by indication films bearing channel numbers positioned in front of neon lamps (64, Fig. 11, not shown) or by a 7 segment display tube.

Abstract: 966,717. X-ray analysis. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 26, 1961 [Jan. 29, 1960], No. 3094/61. Heading G1A. [Also in Divisions F2 and H5] In an analysis apparatus, X-rays 3 impinge on an object 1 so as to produce secondary radiation 5, which is received by the detector 8 of an X-ray spectrometer and is converted thereby into pulses of amplitude proportional to the intensity; these pulses are amplified and supplied to an amplitude filter which has a constant channel height for pulses whose amplitudes lie between two values. As shown, the secondary radiation 5 emitted by the material 1 under investigation passes through a collimator 4, and is reflected by the crystal 6 of an X-ray spectrometer through a further collimator 10 to the detector 8, which is a proportional G-M tube or scintillation counter. The pulses produced have a height inversely proportional to the diffraction angle #, and are passed to a pre-amplifier 14 having a variable control device 15 which corrects this relationship so that at the input of the amplitude filter 13 the pulse height is not dependent upon angle #. This may be effected by constructing the device 15 as a variable potentiometer 18 across the output terminals 16, 17 of the preamplifier 14. A movable tapping 19 on this potentiometer is coupled with the movement of the detector 8, the potentiometer being of the type in' which the resistance as a sine function with linear displacement of the tapping. Alternatively, the resistance itself may be linear, and the movement of the tapping 19 varied as a sine function; Fig. 2 (not shown) is a mechanical linkage for effecting such a movement (see Division F2). The filter 13 passes to the counter 12 only pulses having an amplitude lying within two predetermined values, corresponding to pulses of the first-order deflections.
