Title: Improvements in or relating to engine mountings
Inventor: MORRIS ALBERTO JORGE
IPC: B60K5/12
Filed: 1958-09-24
Abstract: 904,207. Machinery mountings. LISTER & CO. Ltd., R. A. Aug. 5, 1959 [Sept. 24, 1958], No. 30529/58. Class 80 (4). [Also in Group XXXII] In order to provide a resilient mounting for an engine 10 whose shaft 11 drives a wheel 13 through a belt or chain 14, the engine base-plate 16 is, at one side of the engine, pivoted to supports 20 through two axially-spaced stiff rubber bushes 19, and at the other side is supported by two or more soft rubber or spring devices 22. The pivotal axis 18 is parallel to the axis of the shaft 11 and is as close as possible to the driven wheel 13 so that the movements of the engine on its resilient mounting have little effect on the tension of the belt or chain 14. Preferably the axes of the shaft 11, bushes 19 and wheel 13 are contained in a plane Y-Y inclined upwardly away from the devices 22. Each device 22 may comprise a rubber pad or a rubber sleeve held between tapered metal sleeves, and acts at right-angles to the plane X-X containing the pivotal axis 18 and the points of connection of the device 22 and plate 16. The bushes 19 and devices 22 are chosen to avoid resonance at the working engine speed. The structure 15 carrying the supports 20 and devices 22 may be a vehicle chassis.

Title: Regulated oscillator circuit
IPC: H03L5/00
Filed: 1964-08-04
Abstract: 1, 021, 490. Automatic voltage control. NATIONAL CASH REGISTER CO. Aug. 4, 1964 [Sept. 10,1963], No. 30547/64. Heading G3R. A regulated oscillator circuit comprises a transistor amplifier 5 having an input terminal 8 and an output terminal 9; a positive feedback circuit including an emitter follower 10, a resistor 20, capacitors 15, 16 and a frequency determining crystal 17; and a variable impedance circuit shunting the feedback circuit and arranged to attenuate the feedback signal in response to variations in the amplitude of the output oscillations whereby regulation of the output signal is effected. The attenuating circuit includes a resistor 21 and a resistor 22 shunted by a transistor 30 the impedance of which is controlled by a signal derived from the feedback circuit by way of a diode 45. The arrangement is such that the impedance of the attenuating circuit varies inversely in response to changes in amplitude of the feedback signal; the amount of feedback applied to terminal 8 varies accordingly so that the amplitude of the amplifier output signal, being proportional to the signal at terminal 8, is regulated and stabilized.

Abstract: 914,433. Two-part couplings. FOXBORO CO. Sept. 9, 1959 [Sept. 12, 1958], No. 30841/59. Class 38 (1). Electric apparatus, e.g. an electronic controller, includes two units connected together and locked by means which operates a magnetically-controlled switch, the magnet being movable relative to the switch. As shown, a controller 12, which may be mounted with others in a frame, comprises a function generator 16 and a manual regulator 21 connected by pin-andsocket connections and locked together by a key 42 with a bit 44 rotatably mounted on the manual regulator 21 and entering a keyway on the function generator. When the key is looked, a magnetic shunt 74 attached thereto is moved from the path of the magnetic flux between a magnet 72 on the function generator and spaced spring contacts 57, 58 so that the magnetic flux closes the switch. The contacts 57, 58 are disposed within a hermetically-sealed glass envelope 61 carried by a rubber block 63 and a bracket 64 on the manual regulator. A sliding plate 41 on the conductor block 23 of the manual regulator has shoulders which engage the shoulders 87 of a plug 17 to lock it to the manual regulator. A magnet 90 carried by the plate 41 closes a switch 39 when the plate is in the locking position, the switch being open otherwise. Specification 887,004 is referred to.

Abstract: 273,649. Oehmichen, E. July 2, 1926, [Convention date]. Kinematograph apparatus.-The film is held against a support in the exposure position by an interrupted or modulated air current which is delivered approximately normal to the film from a nozzle in an unconfined space; air currents may also be used to cool the lamp house and facilitate the correct running of the film. Fig. 3 shows diagrammatically a film 1 which is held against a flat surface 2, when the current of air supplied by a blower 5 is unobstructed; the current from the blower may be cut off by a screen 3 and the diverted current raises the film from the surface 2, the movement being limited by a frame 4. Stationary or movable studs for positioning the film may be provided in connection with the surface 2. Fig. 4 shows a constructional embodiment in which a chamber 7. directing air on to the film, and having a glass plate 8, is placed between the lamp house 9 and a transparent plate 2 and lens 10. A rotary or reciprocating shutter 3 intermittently obstructs the air current. The shutter 3 may also serve to interrupt the light beam, or a second shutter 11 may be provided for this purpose. Part of the air supplied by the blower 5 may be diverted through conduits 12, 13. to cool the lamp house, and to facilitate the stripping of the film from the intermittent sprocket 6. A flap 15. Fig. 5, pivoted at 16, may also be acted upon by the air, against the action of a spring 18, so as to cause an arm 17 carried by it to press the film intermittently against a fixed edge guide 19.

In operation, the vehicle moves under its own power or is propelled, e.g. by a dolly, until one of its wheels 19 contacts a flap 10 which guides the wheel so as to move the vehicle laterally until the other wheel 19 contacts the other flap 10. Upon further movement of the vehicle the flaps 10 are depressed to operate the switches 14 which are connected in series to ensure simultaneous operation of the motors 9. The guides may, alternatively, be operated hydraulically.

Abstract: 635,227. Reciprocating saws ; percussive drills. SCINTILLA, Ltd. Oct. 22, 1946, Nos. 31358 and 31359. Convention dates, Nov. 24, 1944 and Feb. 15, 1945. [Classes 124 and 145 (ii)] [Also in Groups XXII and XXIV] A motor-driven hand tool for reciprocating a saw, chisel or file has a motor which is mounted in a housing forming the handle of the tool and which drives means for reciprocating the tool at right angles to the axis of rotation of the motor, and a counter-balance system is provided to balance the reciprocating masses. The motor 1 is controlled by a. switch 1<SP>1</SP> and drives a shaft 3 having a pinion 4 which engages gears 5, 6 of equal size mounted on stub shafts. By means of eccentric pins 7 and 20 engaging slots 8 and 21 in the tool carrier 10 and a balance weight 22, respectively, the latter parts are reciprocated at the same speed but in opposite directions. Alternatively, the eccentric pins may be joined by connecting rods to the reciprocating parts or pins on the reciprocating parts may ride in eccentric grooves in the gear wheels. In a modification, the stub shafts may be journalled in an intermediate plate removable with the tool casing so that another implement such as a compressor may be engaged with a dog clutch on the motor shaft. In a modified drive, Fig. 5, a rotatable drum 36 with internal teeth 42 is driven by a pinion 43 on the motor shaft and has a cylindrical crank member 35 eccentrically and rotatably mounted in it. The crank member has a pinion 37 meshing with and rolling round a fixed internal gear ring 41 and also an eccentric crank-pin 38 engaging a collar 50 on the tool carrier. The diameter D of the planetary pinion 37 is half the diameter of the gear ring 41 and the eccentricity K of the pin 38 is half the diameter D so that rotary motion of the drum 36 is converted into reciprocating motion of the tool carrier. The crank member 35 is recessed at 51 on one side so that the remaining mass forms a balance weight. A slotted support plate 19, Fig. 2, for the work is adjustably fitted at one side of the tool casing and has a roller 18 supporting the tool. At the opposite side of the casing a block 28 may be fitted for mounting the tool in a vice. A cover 27 pivoted on a screw 26 is provided.
