Title: Coatings for metallic materials
Inventor: RESTALL JAMES EDWARD
IPC: C23C28/00
Filed: 1964-08-14
Abstract: In a method of coating alloys of Mo, Nb, Ta, W, Ni, Co, Cr with a ceramic material an intermediate coating is formed by diffusion in a non-oxidizing atmosphere.  A Nb-W-Mo alloy is packed in a powder mixture of Si, Fe, Cr and heated to 1100 DEG C. in I2, H2 mixture then in I2, A mixture to form a Nb disilicide layer.  Alternatively a Ti, Cr, Fe or Al layer may be formed.  A coating of Al2O3 is then formed by heating the substrate in a fluidized bed in a stream of steam and AlCl3; the bed may contain SiO2 when an alumina-silicate is deposited.  The ceramic coating may be deposited by spraying or brushing on powder and heating to 1300 DEG C.ALSO:In a method of coating alloys of Mo, Nb, Ta, W, Ni, Co, Cr with a ceramic material an intermediate layer is formed by diffusion in a non oxidizing atmosphere Nb disilicide, Ti, Cr, Al and Fe layers are referred to (see Division C7).

Abstract: 796,570. Combine machines. WHITIN MACHINE WORKS. Nov. 1, 1956 [April 4, 1956], No. 33414/56. Class 120(1) In a Heilmann type combing machine, a spring plate 10 is mounted on the upper surface of the cushion plate 6 for bodily movement therewith, the forward end 14 of plate 10, which is disposed above and normally spaced from the forward end of plate 6, being adapted to be depressed and flexed downwardly towards plate 6 by the upper knife 5. By this arrangement, as the combed fibre fringe is advanced and knife 5 rises, plate 10 also moves away from plate 6 and lifts the fringe to provide easier engagement of the fringe by the detaching rolls 2 and the top comb 7. The top surface of plate 6 is curved to allow gradual flexing of plate 10, the forward end 14 of which is formed with a lip overlapping the forward end of plate 6.

Abstract: 1353081 Fusible cut-outs; two-part couplings MICRO DEVICES CORP 16 July 1971 [10 Aug 1970 28 Dec 1970] 33490/71 Headings H2B and H2E [Also in Division H1] An electrical fuse comprises a thermally responsive fuse 97 mounted in a housing and connected by leads 98, 99 to terminals 72, and heating wires 103, 106 extending in the housing adjacent to but spaced from the fuse 97 and also connected to terminals 72 which can be engaged with the contacts of a mating connector. The fuse 97 is such that the heat produced by an overload current in any of the wires 99, 103, 106 will cause the fuse to blow after a certain time delay. The housing is filled with an electrically insulating material which covers the fuse 97 and the heating wires 103, 106, and secures them in position relative to each other. The fuse includes a pellet which melts at a particular temperature to break the contact through the fuse. A further embodiment includes a heater wire being wound directly on to the fuse and the whole embedded in insulating material (Figs. 20 and 21, not shown).

Abstract: 988,981. Switching transducers. AMPEX CORPORATION. Aug. 23, 1963 [Sept. 4, 1962], No. 33491/63. Heading G5R. [Also in Division H3] An amplifier circuit comprises first and second amplifying devices, a record/playback head coupled to the second amplifying device, the first amplifying device coupling an input signal to the second amplifying device during recording, and a power supply and switching means having first and second positions, the first position coupling the power supply to the second amplifying device during recording and the second position altering the D.C. bias potential of the second amplifying device by coupling a portion of the power supply to the first amplifying device during playback. The circuit shown may be used for recording and playback of speed control signals on a magnetic tape used for recording television signals. Whilst recording, switches 24 and 35 are in the positions shown and a square wave input at 40 is differentiated by resistance 38 and capacitor 39 and applied to the base of a grounded-collector transistor 10. The output of transistor 10 is fed to transistor 11 which feeds the head winding 21. During playback, switches 24 and 25 are in their other positions and transistor 10 serves to apply a fixed bias to transistor 11, all its electrodes being at fixed potentials. Signals from winding 21 are then amplified by transistor 11 and fed through transistor 41 to the output terminal 51.

Title: Improvements in and relating to safety systems for electric elevators
IPC: B66B1/08
Filed: 1927-12-12
Abstract: 282,389. British Thomson-Houston Co., Ltd., (Assignees of Clymer, C. C.). Dec. 15, 1926, [Convention date]. Electric plant.-In order to make it impossible to start an electric lift unless the controller 13 is in neutral position when all the gate contacts 18 are closed, a relay 16 controlling a resistance 17 is connected as shown to the windings 14, 15 of the electromagnets actuating the reversing switches and to the gate contacts. If each of the contacts 18 is closed and the controller is in neutral position, sufficient current will flow through the winding of the relay 16 to cause the shunting of the resistance 17. If the controller is then moved to its first position for hoisting or lowering, one of the switches 14, 15 will be closed and the motor 11 will be connected to the mains through the starting resistance 20. Should the controller be in a hoisting &c. position when the last gate contact is closed, neither of the windings 14, 15 nor the winding of the relay 16 will receive sufficient current to cause the actuation of the devices controlled thereby and the lift will remain stationary.

Title: Carrier current telecommunication system
Inventor: BRADING WILLIAM ARTHUR
IPC: H04J1/14
Filed: 1967-07-21
Abstract: 1,133,439. Carrier systems. STANDARD TELEPHONES & CABLES Ltd. 21 July, 1967, No. 33575/67. Headings H4L and H4R. In a carrier current communication system, e.g. a " Rural carrier " system, signalling information, such as metering pulses, are transmitted by sending either a carrier and lower sideband speech signal or a carrier and upper sideband speech signal, the carrier being shifted between the two conditions so that the signal always occupies the same frequency band in the carrier system. The carrier frequency is detected by the circuit of Fig. 3 in which L resonates with C1 at the higher carrier frequency and with C2 at the lower carrier frequency producing a D.C. output at terminal 3 in one case and at terminal 4 in the other. By using a germanium diode for D1 and a silicon diode for D2 it can be arranged that the actuating mechanism connected to terminals 3 and 4 is in the " off " condition, corresponding to the higher carrier frequency transmission, during complete absence of signal. The speech signal is recovered using a square law characteristic diode as a detector.

[Class 97 (i).] A multifocal lens comprises a basic lens. having a portion thereof forming a distant vision field, and a reading field in the shape of a plane figure lying between the convex sides of two curves which intersect on a vertical axis. In the lens shown the upper portion constitutes the distance field S, Fig. 2, and the lower portion is formed as to its central part as a reading field E of the shape above described,. and as to its lateral parts as fields C, D, having powers less than that of the reading field ; a transition field B is also formed between the distance and reading fields, having a power intermediate between those of the said two fields. The basic or distance lens 1, Fig. 7, is formed on a blank 2, and a circular indentation A overlapping this lens is ground on the blank. Another indentation A<1>, Fig. 8, is then ground into the indentation A to one side thereof, and a button 3, Fig. 9, is cemented into the indentation A<1> and ground flush with the indentation A. A third indentation A<11>, Fig. 10, is then ground into the indentation A to the other side thereof, overlapping the button 3, and a button 4, Fig. 11, is cemented into this indentation and ground flush with the button 3 and indentation A. A further indentation A<111>, Fig. 12, which is deeper than any of those previously formed, is then ground into the buttons 3, 4 and indentation A, and a button 5 is cemented into the indentation A<111> and ground flush with the buttons 3, 4. A further button 6, Fig. 14, is then cemented into the indentation A, covering the buttons 3, 4, 5 and the exposed surface of the button 6 is ground to the contour of the lens 1. The lens 1 is then removed from the blank along the line 17 and forms a multifocal lens as shown in Fig. 2. The crosssection of the lens is shown in Fig. 17. The several buttons may be fused into the basic lens instead of being cemented thereto. In another method of making the lens, all the indentations are formed on the blank, to which is then fused a single button having a curvature corresponding to that of the deepest indentation.
