Title: Improvements in starting and stopping mechanism for talking machines
IPC: G11B17/02
Filed: 1920-07-07
Abstract: 147,188. Regina Co., (Assignees of Wills, M. M.). April 8, 1919, [Convention date]. Periodic; disk.-A brake is applied to the governor-shaft of a phonograph either by hand, or automatically by the movement of the tone-arm. The brake is operated through a rod 37, Fig. 1, by the rotation of a sector 30. When the starting-button 35 is pressed the rod 33, which is separate from the button, is pushed in and turns the sector 30 until a lug 31 on the latter is retained by a catch on the lever arm 28. To apply the brake, the sector 30 is released by a trip lever 25 on the tone-arm engaging a lever 26 on the same shaft as the arm 28, the latter being frictionally rotatable on this shaft to permit adjustment of the time at which it will act. The brake can also be applied manually by pushing the button 34 against the rod 32, the engagement of the arm 28 with the lug 31 being tapered so that they can in this manner be forced apart. The buttons 34, 35 are returned by springs independently of the rods 32, 33. The brake comprises a disk 19, Figs. 3 and 4, freely mounted on the governor shaft but pressed by a spring 18 into frictional engagement with a shoulder 17 formed on the shaft. Normally the disk rotates with the shaft, but when the rod 37 moves to the left in Fig. 1, and to the right in Fig. 3, the crank 39 causes a hook 42 to engage lugs 20 on the disk 19, whereupon friction between the disk 19 and shoulder 17 stops the machine.

Title: Arrangement for scanning radiation-sensitive or radiation-emissive surfaces
IPC: H05B44/00
Filed: 1959-06-05
Abstract: 920,410. Electroluminescence. STANDARD TELEPHONES & CABLES Ltd. June 5, 1959 [June 6, 1958], No. 19314/59. Class 39 (1). [Also in Groups XXXVI, XL (b) and XL (c)] A radiation image pick-up or reproducing device has in series with each picture element of the radiation sensitive or radiation emissive surface a corresponding photo-conductive element which is optically shielded from the radiation at the surface and which when unilluminated effectively blocks an electric current to the picture element; to provide a scanning sequence each photo-conductive element is illuminated in turn by sequential excitation of an array of electroluminescent cells each including a photoconductive element as a component part. The Figure shows a panel in which the radiation sensitive or radiation emitting surface 1 (4) for an image converter or television system is backed by an array of electroluminescent cells. Each cell is composed of a pair of opposed transparent insulating blocks 55, 56, adjacent faces being coated with transparent conductive layers 32, 57 and sandwiching between them a strip 54 of electroluminescent material. The blocks 55, 56 support photo-conductive layers 15, 17 and are surrounded by light-shielding material 63. Photo-conductive layer 15 is connected at one edge to lead 49 of an electroluminescence excitation voltage supply and at the other edge to lead 61 which extends to an individual picture element area of layer 1 (4). Photo-conductive layer 17 is in contact at one edge via an opaque conductive layer between adjacent blocks 56 with the conductive layer 57 of the next cell in a row and at the opposite edge with either lead 27 or 28 (adjacent cells being connected alternately to these leads), leads 27, 28 being connected to pulse generators. These pulse generators operate alternately so that two cells virtually cannot be switched on at the same time. Alternatively, each electroluminescent element may be shunted by a further photo-conductive layer which is optically coupled to it in the same cell; after illumination due to a supply pulse the resistance of this photo-conductive layer remains low, thereby preventing re-excitation of the electroluminescent layer. Successive cells are switched on one at a time in sequence along the array of cells, a separate pulse being provided for switching on the first cell of the array. In a radar display system a row of switching electroluminescent cells mounted as a rotating arm moves over a viewing panel comprising photo-conductive and electroluminescent layers separated by an opaque conductive layer.

Abstract: 809,431. Two-part couplings. STANDARD TELEPHONES & CABLES Ltd. July 1, 1955 [July 2, 1954], No. 19439/54. Class 38 (1). [Also in Group XXXVII] A relay (see Group XXXVII) has a frame part 2 connected to a plug member 74, the ends of the relay contact blades extending into plug slots 75, 76. The cross-sections of the two slots are different and they receive similar-shaped projections 78, 79 on the socket 77 whereby incorrect insertion of the plug is prevented. Apertures 80, 81 extend right through the socket and each contains a spring, Fig. 19, receiving at the front end 91 a relay blade. A projection 93 in the aperture engages a spring tongue 95 to prevent rearward displacement of the spring, the latter may, however, be moved rearwardly to permit connection of the wire to the lugs 94 by inserting a tool, Fig. 21, into the slot 96 and deflecting the tongue, the spring then being retained by engagement of the knee 97 with the projection 93. The spring may be completely removed from the aperture by further use of the tool to depress the knee below the projection. Socket-mounting screw 82, 83 enter holes 84, 85 in the plug 74 and serve to correctly align the latter, the plug being fixed to the socket by three screws trapped in holes 86 ... 88; alternatively (Fig. 22, not shown), spring-loaded trapped bolts may be used. The holes 84 ... 88 are provided in three lugs arranged to permit interlacing of the relays one above another. To ensure that only a particular plug may be mounted in a given socket an index plate carrying a number of specially arranged pins may be mounted between the projections 78, 79, these pins entering similarly arranged holes in the correct plug. Specifications 809,433, 809,434, [both in Group XXXVII], 809,435, 809,436, 809,437 and 809,438, [both in Group XXXVI], are referred to.

Title: Improvements in and relating to methods of and apparatus for regulating the voltage of electric generators
IPC: H02P9/24
Filed: 1954-07-02
Abstract: 792,226. Automatic voltage and speed control systems. IGRANIC ELECTRIC CO., Ltd. July 2, 1954 [July 2, 1953], No. 19443/54. Class 38 (4). [Also in Group XXXVII] The output voltage of a constant-speed, constant load, D.C. generator is maintained in correspondence with a variable voltage applied to its field by measuring any deviation and temporarily applying a large correcting signal so as to overcome ambiguity due to hysteresis of the generator iron. As applied to equalizing the speeds of electric motors driving a series of rollers the Ward-Leonard generator 11 has its field 12 excited via contacts 15a, 16a by a tachometer generator 14 which is driven by the preceding rollers. The generator 11 supplies a roll motor 13. The field 12 and exciter 14 form one diagonal of a normally balanced bridge 17, 18, 19, 20, the other diagonal of which is connected to D.C. supply mains L3, L4. If the portion of the generator voltage tapped off a potentiometer 24 exceeds the voltage of the exciter 14 by an amount greater than a reference voltage tapped off resistor 20, then a thyratron 21 fires and energizes relay 15 to open the normal excitation loop and unbalance the bridge so that a current opposing the exciter 14 flows in the full circuit. Deviations in the opposite sense are similarly corrected by thyratron 22 and relay 16. The relays 15 and 16 are slugged so that the correcting current flows long enough to change the generator magnetic field beyond the value which causes the desired output voltage. In a modification, Fig. 2 (not shown), the bridge resistor 18 is untapped, and a second tapping is added to resistor 17. In another modification, Fig. 3 (not shown), the exciter and the generator field winding are connected in opposite arms of a bridge across a D.C. supply, the resistance arms of the bridge being shorted out directly by thyratrons controlled as above. An inductance in the voltage measuring circuit provides integral action to ensure the desired overshoot. In an embodiment for an unspecified purpose, Fig. 4, the generator 71, which supplies the motor 72, is self-excited via three ganged field regulators 75, 76, 78. Either regulator 75 or 78 may be shorted out by slugged relays 79 or 80 under control of thyratrons 88, 85 to increase or decrease the field excitation. The thyratrons 88, 85 fire if the difference between a reference battery 84 and a portion of the generator voltage tapped off a potentiometer 82 is less or greater than a portion of the generator voltage tapped off a potentiometer 81. The potentiometer 81 is ganged with the field regulators 75, 76, 78, so that the generator voltage will correspond to the setting of the regulators. In a modification, Fig. 5 (not shown), the battery 84 and rectifier are replaced by a non-linear resistor. In a further modification, Fig. 6 (not shown), the correcting voltage and the reference voltage are derived from a single external D.C. source.

Abstract: 1315744 Graphite filaments CELANESE CORP 9 June 1971 [10 June 1970] 19560/71 Heading C1A In the process of preparing graphite filaments by passing a filamentary material continuously through a heating zone containing an inert gaseous atmosphere and heated to a temp. of at least 2000 C., the material retaining its filamentary configuration, there is introduced into the heating zone, the vapour of an alkyl borate. The filament 1, which may be a tape, tow, strand or cable but is preferably a multifilament yarn, is passed into induction furnace 2 via an entrance tube 10 and then into furnace tube 6 which is heated by a water-cooled copper coil 4 connected to a power source 8 and out through tube 16. Nitrogen is admitted to the furnace by line 24, and also passes through branch 26 where it eventually bubbles through an alkyl borate in the liquid phase and the vapour so formed is introduced into entrance tube 10. The preferred borate is a trialkylborate in which the alkyl groups contain 1-5 carbon atoms. The alkyl borate may be introduced mixed with an inert gas which mixture contains 200-2000 p.p.m. by volume of the alkyl borate and is supplied in a quantity sufficient to provide 0À4 to 4À0% by wt. of borate based on the weight of filamentary material. The mixture is preferably brought into contact with the filament before it is heated above 500 C. The temperature during graphitization reaches 2400 to 3100 C. The filament may be a pre-carbonized filament, or may be a filamentary organic polymeric material which has been thermally stabilized, e.g. by oxidation, when the filamentary material is both carbonized and graphitized during the process. The thermally stabilized filament may contain at least 7% by wt. oxygen.
