Title: An improved heat engine operated by the force of expansion of a liquid
IPC: F03G5/00
Filed: 1922-02-21
Abstract: 202,337. Malone, J. F. J. Feb. 21, 1922. Motors operated by the force of expansion and contraction of liquids by heat and cold. - A heat. engine comprises an arrangement in which a working liquid of high thermal conductivity is alternately displaced by a ram or plunger from one end to the other of a cylinder the ends of which are maintained at a difference of temperature by external means. Within the cvlinder 1 a displacer 24, which is porous to allow the passage of the mercury or other working liquid, is adapted to move with the plunger 3 for a part only of the stroke of the latter by means of a spring projection 29 and recesses 31, 32. During the first part of the outward stroke, the displace,r 24 moves with the plunger 3 and the main portion of the liquid is displaced from the hot end 23 to the cold end 19 of the cylinder. This part of the stroke is effected at constant low pressure. During the remainder of the outward stroke, the displacer is held and the plunger forces the liquid up to a high pressure, at the same time displacing the remainder of the liquid to the cold end. During the first part of the inward stroke, the plunger and displacer move together transferring the main portion of the liquid to the hot end. This is accomplished at high pressure, and the displacer is now held while the plunger completes its stroke transferring the remainder of the liquid to the hot end and allowing the pressure to fall.

Title: Improvements in or relating to phase change integrating systems
Inventor: EAST PETER WILLIAM
IPC: G01S13/50
Filed: 1971-02-22
Abstract: 1279582 Radar MULLARD Ltd 22 Feb 1971 5089/71 Heading H4D [Also in Division G4] Apparatus, particularly for use in a Doppler radar system to determine the distance moved by an object comprises a phase discriminator to derive a wave indicative of relative phase changes of a reference and a reflected wave, and a logic system to derive the sine and cosine functions of this difference wave and to supply binary indications a, b of the sign of these functions, the set (a, b) defining the quadrant of the phase of the wave, a change in either quantity indicating a change of quadrant which changes are monitored and counted at CT, to provide digital indication of the distance moved by an object. (A distance of 1 wavelength provides a 2 wavelength change in path length and an 8 quadrant change in relative phase.) The outputs a, b of the logic system are fed to two bistables to produce additional outputs c, d, the outputs together with their complements are fed to 12 AND gates as illustrated. Initially, in the absence of any phase change, a=c; b=d and no gate is enabled. In the event of a or b changing in binary value, the equalities are no longer satisfied since the bi-stables require a resetting pulse to change their outputs, and one of A1- A4, and one from either A11-A14 or A21-A24 is enabled, causing triggering of a monostable M, to enable gates A5, A6 to pass the output from one of OR gates 02, 03 to the counter CT which counts "up" if an output from A5 is present or "down" if from A6. The trailing face of the pulse from M1 triggers a second monostable M2 to apply a clock pulse to the bi-stables B1, B2 to once more render their outputs c, d consistent with the inputs a, b and disable all the gates in readiness of a further change. Counter CT thus provides an integral with respect to the sign of all phase changes occurring over the measurement period, which count is displayed at VD together with a direction indication bit D1 in the m.s.d. position which displays the sign of the summation and hence the direction of movement of the object. To sample the gates A11-A14, A21-A24 at regular time intervals, the monostable M1 and gates A1-A4 may be replaced by a clock pulse generator. It is stated that the invention is advantageous in extremely noisy environments.

Filed: 1929-02-20
Abstract: 306,507. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Feb. 22, 1928, [Convention date]. Electric clocks.-An electric clock system includes two or more master clocks so arranged that when the principal (controlling) master clock fails the control is automatically transferred to another master clock. The Figure shows two master clocks I, II, and the device for transferring the control from one master to the other, the device being also shown as operating a secondary clock dial. Normally only one master is supplied with current. The two masters I and II having contacts wand x send impulses to secondary clocks and striking mechanism every minute or half-minute through a relay y in series with coils b, b of magnet a, the armature c of which operates the clockwork mechanism f to the hands through spring g and pawl and ratchet d, e. The armature c has an arm h with a pin i which bears on a finger k of cylinder l. As soon as the armature reaches its limiting position counter clockwise another impulse is sent from the clock I and the armature is attracted clockwise. Should the master clock I fail the arm h and pin i move on beyond their normal limit and the cylinder l is moved until the end of a lever m snaps up into a notch in this cylinder. Normally this arm m, which carries a mercury switch q, rides on the periphery of the cylinder but when it enters the notch the switch is rocked clockwise and the line v (instead of line u) is brought into circuit to employ the clock II instead of the clock I. The clock I may fail, with its contacts closed and the armature c in the attracted position so that the switch q is not operated. To avoid this a lever p carrying a mercury switch r is used. Each time the armature is attracted a pin o thereon tilts this switch so that the circuit of a heating coil s with bimetallic strip is closed. Normally the circuit is again broken at r immediately, but if the armature c remains attracted switch r remains closed and the bimetallic strip is heated until it bends and releases a spring t which operates cyinder and arm m to change the control to clock II. Lever p and switch r may be omitted and coil s connected directly in the circuit of coils b, b.

Title: Electric starting installations for internal combustion engines
Filed: 1936-02-26
Abstract: 451,212. Starting prime movers. SCINTILLA, Ltd., Soleure, Switzerland. Feb. 26, 1936, No. 5745. Convention date, Feb. 26, 1935. [Class 38 (iv)] In a starting system for internal-combustion engines two or more motors are used to effect starting, the motors are prevented from becoming operative until their pinions have engaged the driving gear and means are provided whereby any or all of the motors may be used in the starting. Two starting motors E1, E2 have their circuits controlled by electromagnetic switches K1, K2 which, in the open position prepare circuits through an auxiliary field windings D1, D2 to effect slow turning of the motors in the reverse direction before starting. These circuits are completed through the contacts 85, 86 and 91, 92 of selector switches S1, S2, corresponding to each of the motors, when a hand switch M is moved into a position connecting a terminal 55 to the batteries B. Switch M is then moved over to contact 56 whereby electromagnets F1, F2 are energized through contacts 84, 86 and 90, 93 of switches S1, S2 so as to move the motor armatures axially to engage the pinions. Engagement of the pinions closes switches G1, G2 which are in series with each other in the circuits of coils J1, J2 operating the switches K1, K2. Thus, when all the motor pinions are engaged switches K1, K2 connect the starting motors through main field windings C1, C2 to the supply in the correct direction. Auxiliary contacts N1, N2 effect connection of the windings D1, D2 in shunt with their respective armatures to assist the main windings. If one of the motors is to be rendered inoperative the corresponding switch S1 or S2 is operated to open the initial circuits for the windings D1, D2 and the electromagnets F1, F2 and at the same to close a circuit shunting the corresponding armature operated switch G1 or G2 at contacts 83, 88 or 89, 94. so as to permit starting even with one of these switches open. An overrunning clutch may be interposed between the rotor of each motor and its pinion shaft. Specification 399,278 is referred to.

Title: Improvements in or relating to radio transmission systems for stereophonic signals and transmitters and receivers for use therein
Inventor: BOELENS WILLEM W
IPC: H04H20/88
Filed: 1952-03-05
Abstract: 704,221. Multiplex radio signalling PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 5, 1952 [April 28, 1951], No. 5761/52. Class 40 (5) Relates to a radio system for transmitting on a single carrier wave a pair of coherent stereophonic signals A and B. The two signals are produced by microphones 1, 2, Fig. 1, located on an artificial head 3. Their sum A + B is fed to channel 4 and their difference A - B to channel 5. The sum signal, developed across resistance 40 amplitude modulates, in valve 10, carrier derived from the source 17, the modulated carrier being fed to the aerial 21, through a coupling network 20. The difference signal is integrated in network 22, which has a resistive input impedance substantially equal to resistance 40, throughout the frequency range, and then is fed to the amplitude modulator 27, 27<SP>1</SP>. The latter is balanced, to suppress the carrier, which is derived from source 17, its phase however being shifted by 90 degrees m circuit 46. The sidebands from the modulator are fed to aerial 21, through network 20, such as that described in Specification 635,830, which is provided to prevent interaction between the two modulators. In one embodiment of receiver, the I.F. output from the superheterodyne circuit 48, 49, Fig. 2, is applied to the two channel demodulators 51, 53 and to a carrier wave filter 52. The latter comprises a valve 55 feeding a circuit 54 tuned to the carrier frequency and the selectivity of which is increased by including it in the anode circuit of a back-coupled valve 556. The extracted carrier is applied directly from circuit 54 to the suppressor grid of valve 58 in channel 51, the incoming signal being applied to the control grid. The demodulated output consists of the sum signal A + B. The tuned circuit 64, coupled to circuit 54, supplies a car rier shifted in phase by 90 degrees, which is fed to the suppressor grid of valve 61 in channel 53. The incoming signal is applied to the control grid and the demodulated output consists of the difference signal A-B. The outputs of circuits 51, 53 are added to apply signal A to reproducer 66 and subtracted to apply signal B to reproducer 67. In a further type of receiver circuit, Fig. 3 (not shown), the sum signal is derived from a simple amplitude demodulator and the difference signal from a known frequency demodulator. The latter is possible as the sidebands associated with this channel are present with a carrier 90 degrees phase displaced relative to the carrier which was amplitude modulated to produce them at the transmitter.
