Title: Improvements in electric incandescent filament lamps of tubular form
IPC: H01K1/24
Filed: 1933-11-21
Abstract: 424,708. Electric incandescent lamp filaments. MAYER, H., 47, Corringham Road, Golders Green, London. Nov. 21, 1933, No. 32536. [Class 39 (ii)] In tubular electric incandescent lamps, having a filament extending longitudinally within the tube, more particularly when the tube is of opal, frosted, or painted glass, the filament is spaced from the end walls of the tube and the length of actual filament wire per unit length of tube is increased towards either or both ends to increase the local light emission to compensate for such spacing. In one form the filament 3, Fig. 1, is arranged obliquely to the axis of the tube at 3<a> and its extreme end portion 3b is then arranged transversely of the tube, current being led to the end of the filament by a leading-in wire 8. Tne filament is supported within the tube by pigtails 4 secured by fusion to glass beads 6 fused on a longitudinal supporting-wire 5 which is maintained in position by lateral stays 7 radiating therefrom. In a another form the filament at its end is bent into a circular arc 3d, Fig. 4, lying in a plane at right-angles to the axis of the tube, or the end portion of the filament may be kinked, wound into a loop, or into a helix which may be of decreasing pitch or increasing diameter. To neutralize or eliminate the effect of an unduly brilliant spot of light at the end of the tube a short length of conductor of different resistance may be introduced into the filament to emit less light, or a part of the filament may be short circuited, for example by electrically connecting two or more pigtails. A short length of filament may also be cooled by grouping a number of pigtails together as shown at 4<a>, Fig. 6.

Title: Power operated torque-applying tools, such as socket wrenches
IPC: B23P19/06
Filed: 1952-12-30
Abstract: 729,960. Screwing-up and unscrewing bolts etc.; tapping. HAUTAU, L. A., and HAUTAU, C. F. Dec. 30, 1952, No. 33015/52. Class 83 (3). In a machine for screwing-up fasteners, such as bolts 87, or for tapping, the wrench 100 is rotated by a hydraulic motor 28 through gearing 50, 51 and is fed axially by a hydraulic motor 28 through gearing 50, 51 and is fed axially by a hydraulic or pneumatic jack 30, the speed and torque of the motor at various stages being controlled by means including relays, contactors and solenoids and also an adjustable spring-loaded feeler rod 84 which extends through the wrench socket 29 so that it can engage the head of the bolt 87. A pump 20 supplies the motor 28 and, at the beginning of the operation, a solenoid 34 sets a valve in the pump so that the supply passes through a flow-control valve 23 to rotate the motor at low speed and torque while a solenoidoperated valve 33 is set to supply air to the jack 30 to hold the wrench in the retracted position. The operator then closes a switch to set the valve 33 so that the wrench is lowered to engage the socket with the bolt head and start the bolt on the threads. When the socket has engaged the bolt head by a small amount, movement of the feeler rod is arrested by the bolt head while the wrench continues to move until, after a predetermined movement, the roller 74 of a switch 55 carried by the wrench disengages from an arm 73 on the feeler rod. The switch 55 then closes and energizes a solenoid 37 that opens a valve 25 so that an increased flow of fluid is supplied to the motor through a by-pass line 26 and flow-control valve 24, thus rotating the wrench at high speed and low torque. At a predetermined position in the downward movement of the wrench, the undersurface of a collar 104 carried by it contacts the roller 106 of a switch 56 on the stationary wrench-housing to energize the solenoid 34, so that the pump operates at high pressure, and de-energize the solenoid 37 so that the fluid flow is reduced, the wrench thus being driven at low speed and high torque forthe final tightening of the bolt. When, owing to increase, resistance to turning of the bolt, the pressure in the supply line 22 to the motor rises, a pressure valve 27 closes a valve 27a (not shown), but the wrench continues to rotate until one of several buttons 105 on the collar 104 contacts the roller 107 of a switch 58 in series with the switch 27a. The closure of the two switches 27a and 58 de-energizes the solenoid 34 so that the pump again supplies at low pressure with the result that the motor stalls,. the wrench stopping at the required position since the number of buttons 105 corresponds to the number of faces on the bolt head. The wrench housing is adjustable on a pillar 14 and the downward movement of the wrench is limited by the abutment of an adjustable nut 98 with a rubber cushion 61 on the upper end of the gear shaft 60. It is stated that the machine may be used for unscrewing or for tapping.

Abstract: 617,765. Ice-making. GENERAL MOTORS CORPORATION. Nov. 7, 1946, No. 33068. Convention date, Jan. 7. [Class 29] A grid 15 for an ice tray 10 comprises a longitudinal wall 16, cross walls 18 loosely coupled to the wall 16 and a longitudinal bar 30, with a bulge 31 between each pair of cross walls 18, adapted to be moved longitudinally in slots in the walls 18 by a lever 26 pivoted at 27 to the wall 16 and connected by links 40 to the bar 30. When the lever 26 is first moved the links 40 are forced downwards to prise the first pair of ice blocks free. On further movement of the lever 26 the bar 30 is forced to the right, the bulges 31 forcing free successive pairs of ice blocks by a buckling action. In a modification the rod 30 may be tensioned instead of compressed which frees the ice blocks by the straightening of the bulges 31. Specification 502,278 is referred to.

Abstract: 1478362 Controlling light EASTMAN KODAK CO 29 July 1974 [30 July 1973] 33427/74 Heading G2F An acousto-optic deflector of the type comprising a stepped array of Piezo-electric transducers, whereby the acoustic beam is automatically steered as its frequency is changed to maintain the Bragg diffraction condition over an extended frequency range, is operated only over a predetermined bandwidth having a centre frequency less than the transducer resonant frequency to counteract the reduction of the electro-acoustic conversion efficiency at higher frequencies due for example to losses in the transducer bonding and to compensate for the shift in the resonant frequency of the transducer from its free air value when it is bonded to the elasto-optic medium, whereby a flatter response, diffraction intensity against electrical input, is obtained. The resonant frequency is preferably 30% higher than the centre frequency. The angle of optical incidence may be greater or less than that giving peak response at the centre frequency whereby resolution and diffraction efficiency may be traded one against the other. By closing an angle giving 3dB less response at the centre frequency, the overall 3dB bandwidth can be increased by #2. Design critica, e.g. aperture width, cross-sectional distribution of the optical beam and dimensions of the deflector, are discussed in detail. The step height of the transducer array is an integral number of acoustic half-wavelengths at the centre frequency, with series electrical connections appropriately poled depending on whether the integer is odd or even. Acoustic absorbers are disposed on the surface opposite the transducer array e.g. lead, aluminium or epoxy loaded with tungsten powder, for a lead molybdate elasto-optic mediam and on two sides of the elasto-optic medium, the latter acting also as heat sinks e.g. Al or Cu covered with insulating layers. Finned heat sinks may also be provided for the transducers.
