Abstract: 1338412 Elastic wave amplification WOJSKOWA AKADEMIA TECHNICZNA I JAROSLAWA DABRWOSKIEGO 11 Dec 1970 [13 Dec 1969] 59170/70 Heading H3U A device for amplifying surface or transverse elastic-spin waves comprises a slab 2 of gyromagnetic material, e.g. Y1G, having input and output elastic wave coupling members 4 connected, respectively, to an input wave generator 5 and receiver 7. Mounted on slab 2 is a layer 1 of piezoelectric semi-conductor material, e.g. cadmium sulphide, having terminals 3 connected to a D.C. source 6 go produce an electron drift current therein. The device is situated in a constant magnetic field (not shown) which produces spin-acoustic resonance. In the operation of the device for amplifying surface or transverse waves generated in the slab 2, these waves generate an elastic wave in layer 1 to produce an electric field in the layer due to piezoelectric effect. This field modulates the electron drift current in layer 1 and at a critical velocity of this current equal to the phase velocity of the elastic wave an amplification of this wave in layer 1 occurs. This wave, through mechanical coupling of the layer 1 with slab 2, causes amplification of the elastic-spin wave in the slab 2 and an amplified output is obtained at 7. In a modification (not shown) the composite 1, 2 is replaced by a plurality of piezoelectric semiconducting crystals and ferromagnetic crystals placed alternately one upon another.

Title: Heat engine and a method of putting this engine into action
IPC: F02B19/02
Filed: 1970-12-16
Abstract: 1331070 Six-stroke cycle I. C. engine M MILISAVLJEVIC 16 Dec 1970 [17 Dec 1969] 59661/70 Heading F1B A six-stroke cycle heat engine has a combustion chamber 14 in which a fuel-air mixture is burnt under constant volume conditions and then transferred to the space above a piston 4 reciprocating in a cylinder 1. The engine comprises an inlet valve 9 through which fresh air is induced during the downward stroke of the piston 1, a valve 15 in the transfer passage 13 and an exhaust valve 19 in the combustion chamber 14. All the valves are operated by cams 11, 17 and 21 respectively which are mounted on a cam-shaft driven from the crankshaft 5 at one-third of the speed thereof, each of the valves being spring-biased to the open position. A fuel injector and sparking plug, also controlled by the crank-shaft are mounted in the combustion chamber wall. The cycle of operation is as follows: At the beginning of a first downward stroke of the piston, exhaust valve 19 and transfer valve 15 are closed and inlet valve 9 is open. At the beginning of the first upward stroke, inlet valve 9 is closed, transfer valve 15 is opened and exhaust valve 19 is opened briefly to allow scavenging of the combustion chamber and then closed, so that the air above the piston fills the chamber and is compressed therein. The transfer valve is then closed and the inlet valve opened as the piston commences to move downwardly on its third stroke. During this stroke the fuel is injected into the combustion chamber and the mixture is ignited. Combustion continues throughout the third stroke of the piston and the ensuing fourth stroke  during which the air induced in the third stroke is compressed in the space above the piston. As the piston begins to move downwardly on its fifth stroke, the transfer valve is opened, the inlet and exhaust valves remaining closed and the gases from the combustion chamber expand into the cylinder and continue burning there, as the piston makes its working stroke. During the final stroke of the cycle, as the piston moves upwardly, the inlet valve remains closed, the transfer valve remains open and the exhaust valve is opened so that the burnt gases are expelled. In a modification of the cycle, the exhaust valve is not opened momentarily as the piston moves downwardly on its first stroke, so that the remaining burnt gas is drawn into the cylinder and heats the incoming air.

The tray may be similar to that described in Specification 1325894 having a sheet tensioned over a lattice structure frame; in this case the sheet may be fixed to the cross-member of the lattice structure frame. As shown a mirror is made by heat sealing a film 4 to the rim 3 of a circular disc 1 cooled to a temperature of -20‹C. The disc gradually warms up and tensions the film in a uniform manner. As the disc warms up air trapped between the film and the concave upper surface 2 of the disc increases in temperature and pressure so that the upper surface of the film becomes slightly convex. Holes may be formed in the disc if the surface of the mirror is required to be flat. The sheet may be made of metal or of a metallized thermoplastic material; the frame may be made of a thermoplastic material or metal. In another embodiment a rear-viewing mirror for a motor vehicle comprises a film fixed to an outer surrounding rim and an inner circular rim of a rectangular plate. Air may be injected into the space between the plate and the part of the film bounded by the circular rim to form a mirror which is part plane and part convex.

Abstract: 675,048. Gyroscopic apparatus. SPERRY CORPORATION. March 29, 1950 [April 1, 1949], No. 7850/50. Class 97 (iii). [Also in Group XXXVII] In a gyroscopic apparatus comprising a rotor-bearing frame 13, Fig. 2, mounted about inner gimbal axis 14 and outer gimbal axis 12 in a supporting outer frame or casing 10 and an arrangement for quickly accelerating the rotor 18 to its normal running speed there is provided means for quickly bringing the rotor-bearing frame 13 substantially to a predetermined position with respect to the outer casing 10 comprising torque-applying means such as the electromagnet 28, 30, 32 fixed to the outer casing 10 and armature 34 fixed to frame 13, operating during at least a portion of the period of rotor acceleration to apply a torque to the frame 13 if the rotor 18 is tilted from the predetermined position with respect to the casing 10, the said torque acting substantially in the plane of tilt and in a sense opposed to the tilt. The casing 10 has an opening 33 and the electromagnet, adjustably mounted on the casing, has a pole-piece 28 in the opening 33. The torque applying means is automatically rendered ineffective after a predetermined interval of time as by a time delay switch 62, Fig. 1, after the application of energy to the rotor-spinning means to initiate acceleration of the rotor 18. The rotor 18 forms the squirrel cage of an A.C. induction motor with an inner wound stator 22, Fig. 2, secured to the frame 13, the stator being fed, for acceleration to normal speed through a step-up transformer 39, Fig. 1, which is connected in circuit between the windings 36 of the stator 22 and the source of power 37. When the apparatus is initially switched on, to apply a higher voltage to the stator than the normal operating voltage and which is disconnected after a predetermined operating voltage and which is disconnected after a predetermined interval of time, e.g. by the time delay switch 62 opening the energizing circuit of a relay 60 which by its contact switches 43, 47 cuts out the transformer 39 and connects the windings 36 directly to the source of power 37. The circuit of the energizing coil 32 of the electromagnet contains the time delay switch 62 and hence the torque applying electromagnetic device and the quick acceleration arrangements of the rotor are rendered ineffective simultaneously. Specification 633,954 is referred to.

Title: A digital frequency discriminator
IPC: G01R23/10
Filed: 1979-03-02
Abstract: In a frequency discriminator whose discriminator curve can easily be modified in respect of centre frequency and gradient and operating in accordance with the time comparison principle, the test signal S(f) is fed via a controlled time gate (TS, ZS) to a counter (ZR) which counts a given number of n pulses of the test signal. The time gate is opened by the rising flank of a reference signal S(fb) and closed. again on the conclusion of the counting. As a result of the comparison of the counting time with the pulse width of the reference signal in a circuit AS, the frequency deviation of the test signal frequency from the theoretical frequency is reflected in the width of a pulse appearing at either f or g in dependence upon the sense of deviation. The centre frequency is changed by changing the reference pulse width or n and the gradient is changed by modifying the integration constants of a follow-up integrating circuitry CV. <IMAGE>
