Title: Improvements in or relating to glass-ceramics and their production and to devices comprising glass-ceramics
Inventor: MCMILLAN PETER WILLIAM
IPC: H05K1/03
Filed: 1960-02-29
Abstract: A ceramic glass body, formed from a heat-sensitive glass by controlled dentrification and which contains a metallic compound reducible to the metal state, is provided with a metallic film on the surface by heat treatment in a reducing atmosphere.  The glasses used are as disclosed in Specifications 924,996 and 943,599 with the addition of copper, silver or gold compounds which are reducible to the metal. Water, up to 5%, may be added to the raw ingredients to assist in the reactions.  The reducing gas may be hydrogen, forming gas (90% N2 + 10% H2) or other mixtures of N2 and H2.  The reducing atmosphere may be maintained throughout the heat treatment or, preferably, an oxidizing atmosphere may be maintained during the initial low temperature procedure.  In example, the temperature is raised at about 20 DEG  C. per minute to the region of the melting-point of the glass and this maintained for at least 1 hour; then raised at less than 2 DEG  C. per minute to 50-200 DEG  C. above the Mg point and this maintained for at least 1 hour; the atmosphere is then purged with N2 and a reducing gas atmosphere substituted; the temperature is then raised at less than 5 DEG  C. per minute to the final crystallization temperature, 850 DEG  to 1,050 DEG  C. depending on the glass, and this maintained for at least 1 hour. Cooling to room temperature at about 10 DEG  C. per minute is then effected, the reducing atmosphere being maintained until the temperature is below 150 DEG  C.  Further ranges of temperatures are given for a different glass range. Immersion of the filmed article in dilute HF for a period of about 5-60 minutes appears to remove a superficial layer of insulating material and leaves a metallic layer of high electrical conductivity.  The filmed bodies may be used as parts for ceramic to metal seals, for capacitors and also for printed circuit components, for which purpose the metal film is etched away from remaining areas, the circuit areas being protected by a suitable coating.

Title: Improved limit-switch mechanism for electric motors
IPC: H02K7/06
Filed: 1946-03-08
Abstract: 609,171. Lifting-jacks. GENERAL MOTORS CORPORATION. March 8, 1946, No. 7243. Convention date, March 14, 1945. [Class 78 (iii)] [Also in Group XXXVII] An electric motor-driven mechanism comprises a screw-shaft and nut, the relative rotation of which by the motor involves a relative longitudinal movement, and a torsion rod fixed at one end to the shaft and at the other to an abutment member, engageable by lugs or the like carried by the nut at the limits of said longitudinal movement, said engagement involving a twisting of the rod and a relative rotation between the shaft and a cam member carried by the rod to operate a motor-stopping switch. A reversible D.C. motor is adapted to be coupled to a screw-shaft 80 carrying a non-rotatable nut 93 which operates limitswitches at opposite ends of its travel to de-energize the motor and stop the mechanism. A torsion rod 90 has one end fixed to the screwshaft 80 and the other end carries an abutment member 115. The member 115 comprises lugs 117 and 118 which are engageable respectively by lugs 109 and 108 carried by the nut 93 when the nut is moved to one of its predetermined stopping - positions. When a lug of the nut engages a lug of the abutment member, the latter is locked against rotation and the torsion rod is twisted. A tubular member 130 is fixed to the lower end of the rod 90 and carries a cam 131 which engages clutch-pins carried by the shaft 80. Twisting of the torsion rod 90 effects relative movement between the screwshaft 80 and the tubular member 130, and the clutch-pins are actuated by the cam to couple a switch actuator 150 to the screw-shaft and operate the appropriate limit switch. A lostmotion coupling between the screw-shaft 80 and the abutment member 115 permits limited relative movement therebetween when the member 115 is locked. When this lost-motion is taken up, pins carried by the screw-shaft positively engage the abutment member and the entire mechanism is stopped. The electric motor may be coaxial with the screw-shaft and drive it through cyclic gearing and an electromagnetic clutch which is energized simultaneously with the motor. Means may be provided to effect manual operation of the mechanism.

Abstract: 607,768. Fusible cut-outs. BRITISH THOMSON-HOUSTON CO., Ltd. April 20, 1944, No. 7353. Convention date, April 23, 1943. [Class 38 (i)] The fusible element of an expulsion-type fuse extends into or through a recess or passage in a closed vessel containing a substance which is released when the wall of the passage is burnt through by the heat of the arc, and produces an arc extinguising fluid jet. As shown, the fusible element 18 extends through a passage 24 in a sealed annular vessel 23 -containing a liquid which forms an arc extinguishing vapour. A flexible cable 17 is supported from a fixed terminal 15 by the fuse 18 soldered in position and reinforced, if necessary, by a strain wire 21, the end of the cable preferably being enclosed within an insulating tube 22. The fuse unit, which may be soldered to the liquid container 25, as shown, has its terminal 15 clamped by a screw cap 13 on to a ferrule 12 mounted on an insulating tube 11. The liquid container may be of metal or moulded plastic material and has an air cushion 27 to allow for thermal expansion. In a modified clamping arrangement, Fig. 2 (not shown), in which the fuse and liquid container are separate units, a narrower expulsion tube which may also generate arc-extinguishing gas, encloses the upper part of the cable. In Fig. 3 (also not shown), an open-type pole-mounted cut-out is arranged so that the flexible cable when expelled hangs down as a visual indication, the whole fixture being hingedly removable for fuse replacement. Suitable liquids for arc quenching are mentioned, including that disclosed in Specification 394,776.

Title: Improvements in and relating to self-synchronous transmissions systems
IPC: G05D3/12
Filed: 1944-04-21
Abstract: 608,217. Remote control systems. SPERRY GYROSCOPE CO., Inc. April 21, 1944, No. 7489. Convention date, Aug. 7, 1942. [Class 40 (i)] Differences between the voltages across corresponding coils of the transmitter and receiver of a selsyn system are amplified and applied to the receiver coils. A relative angular displacement between the rotors of transmitter and receiver will cause the voltages in coils 13 and 17 to differ. The potential difference appearing across resistor 22 is amplified by valve 25 and applied through transformer 26 to the receiver coil in order to balance the voltages in the two coils so that no torque is produced at the transmitter. Instead of two separate secondary coils, as shown, the transmitter and receiver may comprise a pair of joined secondary coils, or three coils connected in γ or delta, the voltages across corresponding coils or pairs of coils being compared and amplified. In a modification, Fig. 6 (not shown), for remote indication of a magnetic compass, the exciting coil is stationary and an armature of magnetically permeable material is rotated within the coil. In order to position a heavy object, Fig. 8 (not shown), the voltage induced in the receiver rotor coil is applied through an amplifier to a motor to drive the rotor into positional correspondence with the transmitter rotor.

Title: Improvements relating to gearing and its application to supercharging internal combustion engines
IPC: F02B33/00
Filed: 1935-03-11
Abstract: 453,497. Variable - speed gearing. WILSON, E. B., and E.N.V. ENGINEERING CO., Ltd., 4, Hythe Road, Willesden, London. March 11, 1935, No. 7554. [Class 80 (ii)] [See also Group XXVI] Gearing for driving the supercharger of an internal-combustion engine at either of two speeds greater than engine speed comprises an epicyclic train 3, 6, 7 in combination with a multiplying train 11, 16, 17. The planet pinions 3 of the epicyclic train are mounted upon a carrier 2 attached to a driving shaft 1 driven from the engine and the annulus 7 drives gears 11 mounted on countershafts 12 with the gears 16 which in turn drive the central gear 17 on a shaft 18 of the impeller 49 of the supercharger. The sun pinion 6 is attached to a member 19 freely rotatable on the driving-shaft 1 and adapted to be held stationary by a brake 29 so that the planet carrier drives the annulus 7 at an increased speed. A one-way clutch 33, 34, 35, 36 of the Humfrey-Sandberg type is provided between the member 19 and the driving shaft 1 so that on release of the brake 29 the sun 6 is prevented from over-running the planet carrier so that the epicyclic gearing rotates solid for a direct drive. Thus two speeds of the impeller 49 both greater than engine speed are obtained by holding or releasing the sun pinion and its supporting member 19. This operation may be effected automatically by means responsive to change in atmospheric pressure so that when used on aircraft the higher speed of the supercharger impeller is brought in at high altitudes. The gears 16 of the multiplying train may also comprise centrifugal clutches 14, 15, 16. Specification 220,021, [Class 103 (i)], is referred to.

Title: Improvements in and relating to load control systems in electric energy consuming and supply installations
IPC: H02J3/14
Filed: 1939-03-09
Abstract: 526,881. Supply meters. SCHILLER. P. March 9, 1939, No. 7576. [Class 37] [Also in Groups XXXV and XXXVII] In a system in which a dispensable load 51 is connected and disconnected by a contactor 48 under the control of a watt-hour meter 1, so that the demand of the supply 49 is maintained at or below a predetermined value, the demand at which the load is disconnected is adjusted by moving a belt 23 on coned pulleys 22, 24 by means of a tuned stepping-magnet 39 which drives a wheel 54. At a certain speed the wheel 54 is coupled to a wheel 36 through a clutch, and a pawl 35 operates a ratchet wheel 34 geared to a wheel 28 operating on the belt 23. The movement of the wheel 36 is against a centring spring 43 and is limited by stops 42, 53. Thus the amount of adjustment is independent of the duration of. the control impulse. A second device shown partly at 45 effects the adjustment in the reverse sense. When full adjustment has been made the wheel 28 which carries an indicating pointer 30, operates on a switch 32 to disconnect the load 51. Where an agreed minimum supply is guaranteed an adjustable stop limits movement of the wheel 28. In a modification, Fig. 2 (not shown), the load is measured by a bi-metallic device co-operating with a second bi-metallic strip to control the dispensable circuit and this second strip is controlled by a resistance varied by movements of the wheel 28. In a further modification, Fig.3 (not shown), the adjustment is effected by a member actuated by two bi-metallic spirals selectively energized under the control of frequency responsive switches.
