Abstract: 894,008. Camera lucida. SCHWARTZ, L. Aug. 12, 1960 [May 15, 1959], No. 36805/58. Classes 97(1) and 98(1) An optical projection apparatus comprises a cabinet having an uppermost transparent or translucent surface on to which is projected an image of an object carried on the lower one of two shelves arranged in the apparatus relatively movable with respect to each other and to the said uppermost surface by gear means the other of the said two shelves carrying an optical projection system and, on the underside of the shelf and laterally flanking the projection system, a plurality of fluorescent lamps in staggered array. As shown in Fig. 1 shafts 20, 21, 22, and 23 extending from the front to the rear of the cabinet carry at each end two sprockets rigid with the shaft and one sprocket freely rotatable on the shaft. The corners of each of the two shelves 4 and 5 are releasably secured to independent chain loops associated one with each shelf and so arranged over the sprockets that a crankwheel 32 geared to shaft 20 will raise and lower only one shelf while a second crankwheel 33 will raise and lower only the other shelf. The crank-wheels may be clamped by milled-headed nuts 34. Fluorescent tubes 9 in staggered array, as indicated in Fig. 2 on either side of the projection lens 7, have their lower sides covered so that an object on shelf 5 receives light diffusedly reflected from the underside of shelf 4. Two lamps 14 mounted on the upper side of shelf 4 facilitate inspection of the image for tracing purposes and the brightness of these may be controlled by a rheostat. The jointed rods 18 carry the electrical leads for the lamps. A hood 43 excludes daylight. A roller blind 38 provides easy access to the interior of the cabinet.

Title: Metallic Member for Semiconductor Devices
IPC: H01L21/56
Filed: 1966-08-17
Abstract: 1,162,163. Manufacturing semi-conductor devices. MOTOROLA Inc. 17 Aug., 1966 [22 Oct., 1965], No. 36890/66. Heading H1K. A stamped metallic strip comprises perhaps one hundred times the basic fragment shown. The strip may be gold-plated before placed in a machine which bonds a semi-conductor die 42 (transistor) to platform 28. Emitter and base wires are then bonded between the die and bonding areas 26 on respective leads 18, 20. The platform is in a lower plane than the general plane of the strip so that the chances of shortcircuiting between the wires and undesired regions of the die are reduced and so that the straight run of the wire gives a strong bond. The strip is located in the machine by indexing holes in the side members 16, 38. After removal of the side member nearest them, many die regions are simultaneously encapsulated in a transfer mould and the remaining interconnecting parts of the strip removed from between the leads. The end portions of the leads 18, 20, 22 are given a generally rounded shape during initial formation of the strip. In a modification the die mounting platform may have an extension (in the direction of the nearest side member) which protrudes from the ultimately encapsulated device to act as a cooling body. Reference has been directed by the Comptroller to Specification 1,105,207.

Abstract: 1,171,094. Driving auxiliary apparatus. RENWICK GARAGES Ltd., and W. J. ALLSOP & SON Ltd. 2 Aug., 1968, No. 37031/68. Heading B7H. [Also in Division F4H] In an ice-cream van, electrical equipment associated with the preparation and storage of confections is powered by an alternator 2 which may be driven by the vehicle engine through an electromagnetic clutch 36 when the vehicle is stationary, and an engine governor is provided to maintain a suitable constant engine speed when the engine is driving the alternator. The equipment comprises an ice-cream freezer having a beater motor and control gear 42 and a condensing unit 44, a condensing unit 46 associated with two storage cabinets (not shown), and thermostat units 48 and 50 controlling refrigerant flow to evaporators in the cabinets. A pressure switch 52 energizes the unit 46 when either unit 48 and 50 is allowing refrigerant flow. A switch 54 may therefore switch off the unit 46. The equipment is powered by the alternator 2 through a switch 40 and fuses 41. A switch 56 is provided to enable the unit 46 to be powered by an external electricity supply 58 when the van is garaged. The clutch 36 for connecting the alternator to the engine is energized from the vehicle battery 60 by closing switches 64 and 66, the latter being closed by applying the vehicle handbrake. Thus the clutch is necessarily inoperative when the van is being driven. A water heater 62 is also powered by the vehicle battery. When the alternator is driven by the engine, the latter is placed under the control of the governor 18 (Fig. 2) whose output arm 22 acts through a lever 24 on a throttle control 26. The arm 22 may be pivoted out of contact with the lever 24 by operation of a cable 34 so that the throttle may be put under driver control when the van is being driven.

Title: Improvements in or relating to electrical arrangements of the kind including a synchronous alternating-current electric motor
Inventor: SIMONS WILLIAM RICHARD
IPC: G01R31/34
Filed: 1963-08-10
Abstract: 1,096,832. Testing electric motors. SMITHS INDUSTRIES Ltd. July 23, 1964 [Aug. 10, 1963], No. 38145/67. Divided out of 1, 096, 831. Heading G1U. A test arrangement for a rate gyroscope comprises means for detecting whether the rotor is free to rotate about its precession axis and further means to detect whether the rotor, driven by a conventional three-phase hysteresis motor is rotating at the desired speed, i.e. the synchronous speed of the motor, this further detecting means being arranged to render the first such means inoperative unless the rotor is rotating at the required speed. The stator coils 25 of the rotor are fed with the three-phase supply through leads 11, 12, 13. A resistor 14 is connected in the lead 13 and the voltage signal across this resistor is applied to a diode detector 15. If the rotor is rotating at synchronous speed the frequency of the voltage signal across the resistor 14 is that of the A. C. supply and this will be amplitude modulated by a low frequency oscillation superimposed by a corresponding low frequency oscillation in the rotor speed, which has been found to be present only at the synchronous speed of the motor. The detector in this condition produces a small output signal at the modulated frequency. This signal is applied through an amplifier 16 to a bi-stable circuit 17. This circuit is arranged to be switched back and forth between its two stable states in response to the amplitude modulations of the voltage signal developed across the resistor 14. The circuit 17 controls a relay 18 and a capacitor 23 effectively slows down the response of the relay 18 so that its contacts 24 remain closed whilst the circuit 17 is being switched back and forth between its two stable states at the modulating frequency due to the presence of the amplitude modulation detected by the diode detector 15. If the motor is not rotating at its synchronous speed then the contacts 24 remain open. The contacts 24 are connected in circuit with a winding 19 which may be energized by operating a switch 20 to exert a torque on the gyro rotor and thus test for freedom of the gyro to precess.
