Title: Cold-cathode tubes
Inventor: HART MICHAEL JAMES
IPC: H01J17/00
Filed: 1958-07-16
Abstract: 825,360. Cold-cathode tubes. MULLARD Ltd. July 16, 1958, No. 22852/58. Class 39(1). In a cold-cathode discharge tube comprising a cathodeelectrode in the form of a partcylindrical metal plate and an anode electrode supported on a base, together with connections to said electrodes, which connections extend through the base, the said electrodes are so arranged that in operation the discharge will strike between those extremities of the anode and cathode which are remote from the base, and the said cathode extremity has a cleaner surface than the remainder of the cathode. The tube shown comprises a cathode 1 mounted on supports 3 secured in seals 4 forming part of the base 10. An anode rod 2 is welded to a member 5 held in further seals 4. Connections to the electrodes are made through pins (not shown) passing through the appropriate seals 4. The upper end of the anode 2 is provided with a cross-piece 7 so dimensioned that the distances between the ends of the cross-piece and the closest portions of the cathode 1 are less than the distances between any other portions of the cathode and a conductive member, e.g. the distance 6 between the bottom edge of the cathode and member 5. The anode rod 2 may be inclined towards the cathode 1. In alternative arrangements, Figs. 3 and 4 (not shown), the upper end of the anode rod 2 is bent over towards the cathode in the form of a part loop or a radial projection. In a further alternative arrangement, Fig. 5 (not shown) the ends of the member 5 adjacent the cathode 1 are coated with insulating material to prevent a discharge striking at these points. When the cathode 1 is heated during processing, the upper portion will be hotter than the lower portion, since heat is conducted away from the lower portion by the supports 3. Consequently the upper portion of the cathode will be cleaner than the lower portion. The discharge thus always strikes to the cleaner portion of the cathode, and the striking voltage is stable so that the tube is suitable for use as a voltage reference tube. The invention is also applicable to tubes having electrodes additional to the anode and cathode, e.g. trigger tubes.

Title: Improvements relating to braking systems
IPC: B60T11/224
Filed: 1939-08-08
Abstract: 538,785. Hydraulic brakes. SAUZEDDE, C., and DETROIT HYDROSTATIC BRAKE CORPORATION. Aug. 8, 1939, No. 22862. [Class 103 (i)] In a hydraulic master cylinder for brake operation having a low pressure piston for taking up the clearance between the brake shoes and drum and which is then rendered ineffective and a high pressure piston for applying the brake pressure, the low pressure piston is operated by a spring and forces liquid to the system through the high pressure piston past a valve which prevents return of the liquid when the high-pressure piston alone is effective. A closed flexible replenishing reservoir subject to spring pressure may be provided. The high-pressure piston 11 rests at its rear end on a member 19 engaged by the pedal operated push-rod 20 and has a bore 11b and radial ports 11d by which the chamber 10d normally communicates with the chamber 10a connected by port 10h to the brakes, a valve 32 being normally unseated. The lowpressure piston 27 is slidable or the member 19 and a spring 25 normally rests upon collars 21a, 22 on the rod so that it is ineffective. The piston 11 is sealed by an elastic member 15 secured to the piston and to the casing 10 and the piston 27 is sealed by an elastic member 28 of Z-form secured to member 19 and to the casing. A closed replenishing reservoir 35 is of flexible material acted upon by a spring 37 and normally connected to chamber 10a through port 10f. The whole system is thus closed from the atmosphere. Upon operation of the rod 20 to apply the brakes, the movement of the collar 22 causes the spring 25 to be effective on the piston 27 which then moves with the member 19 and piston 11, the valve 32 becoming seated on the end of the piston. Liquid is thus forced through the port 10h to the brakes both by piston 11 and through the bore 11b past valve 32 by the piston 27. When, consequent upon application of the brake, the pressure rises sufficiently to overcome the pressure of the spring 25, the piston 27 ceases to move forwardly, and returns slightly against the action of the spring, to compensate for the further advance of the member 10 into chamber 10d. The piston 11 alone is then effective. During release, the parts 11, 19, 20 return to normal positon and the valve 32 being then unseated, the piston 27 is able to return until it abuts again on the spring 25,

Title: Motor control circuits
IPC: H02P25/024
Filed: 1972-05-16
Abstract: 1342868 Control of AC motors HOLZER PATENT AG 16 May 1972 [19 May 1971] 22916/72 Heading H2J  Asynchronous motor 4 is supplied with alternating current consisting of half-waves from an A.C. supply 8 passed by a diode 2 through the motor and a capacitor 3, which is charged thereby, and half-waves of opposite polarity produced by discharge of the capacitor 3 through the motor winding when a thyristor 6 is fired at the end of the supply half-wave, the capacitor being chosen to resonate with the motor winding to produce a current of sine waveform. The firing signals are produced by a transistor 14 when the temperature-dependent resistor 12 of a bridge circuit 10 ... 13 heats up, for example when the water in a washing machine including the motor reaches a predetermined temperature. Capacitor 15 ensures that the transistor 14 only conducts at the appropriate points of the supply waveform, Figs. 5a, 5b, and 5c (not shown), cessation of the firing signals causing the motor to stop after a half-wave from the supply has charged the capacitor 3 ready for the next motor operation. Current limitation is provided by resistors 5, 5<SP>1</SP>, one or both of which may be connected in series with a resistor 1 via changeover contacts ab, cd. The values of resistors 1, 5, 5<SP>1</SP> may be chosen to produce equal charge and discharge currents for the capacitor 3. In Fig. 6 the motor 4 drives, via gearing 32, the cam 40 of the programme switch of a washing machine, a further motor 20 also driving this cam through gearing 23, 24 and an eccentric pawl 26. The cam 40 controls contacts 27, 28, 41 and 42 and the motor 20 actuates, via members 23, 29, 30, reversing contacts 31 for the washing machine drive motor. In a typical operation of the motor 4, a thermostat 7 responsive to the water temperature causes the thyristor 6 to be fired when a predetermined temperature is reached and contacts 42 have been closed. Motor 4 then rotates to drive the cam 40 rapidly to execute a number of programme steps, after which contacts 42 are opened by the cam to stop the motor. While the water is heating up, contacts 27 and 28 are closed to keep the pawl 26 out of contact with the cam 40 and to energize the heating element 21 of the machine.

Title: Radio receiver tuning or control element slide drive arrangement
IPC: H03J1/10
Filed: 1973-05-15
Abstract: 1429337 Linkwork; sliding bearings INTERNATIONAL STANDARD ELECTRIC CORP 15 May 1973 [15 May 1972] 23013/73 Headings F2A and F2K [Also in Division H3] In a radio receiver tuning or control element slide drive arrangement including a slide block 1 which can be guided along an edge 13 of a first wall 3 in or of the cabinet of the radio receiver and a runner 2 slidable separately from the slide block along an edge 8 of a second wall 5 in or of the cabinet of the radio receiver parallel to the first wall 3, the slide block 1 and the runner 2 are coupled by one or more pins or noses 18 on one of the slide block 1 or the runner 2 which engage slots or recesses 19 in the other of the slide block 1 or runner 2 so that there is substantially no play between them in the directions of sliding along the edges, while play is possible between them in directions at right angles to the two walls 3 and 5 to an extent corresponding at least to the largest amount of a sagging or bowing of the two walls. The edge 13 may be of a transparent cover for a dial and the edge 8 may be of the frequency or tuning dial of the radio receiver. A pointer portion 6 is shown moulded to the runner 2 and a guide groove 7 in the runner is sufficiently wide to receive the sagging of the second wall 5 along its length. A cord drive 9 is linked to the runner 2 by a wedge 11. The slide block 1 may be snapped on to or off of the beaded edge 13 due to resilient arms 21 which grip the edge 13 and compensate for any existing sagging or bending of the wall 3 and for sagging due to the operator of the radio receiver when touching and moving the slide block 1. The slide block 1 contains two friction wheels 16 whose rotation causes a force to be exerted on the wall 3 and enables a fine adjustment of the block 1 to be made. The slide block 1 is coupled to the runner 2 by two pins 18 which engage within slots 19 so as to allow perpendicular movement of the slide block 1 with respect to the runner 2 to allow for bowing or sagging of the walls 3 and 5. The cord 9 may be fixed to the runner 2 by a three pronged rake around the prongs of which the cord is threaded or by a slot at right angles to the groove 10 instead of the wedge 1. The tuning or control element may be set directly rather than indirectly via a cord drive, e.g. if the tuning element is a sliding potentiometer for setting a voltage across a variable capacitor.

Title: Improvements in or relating to magnesium alloys and method of making same
IPC: C22C1/03
Filed: 1951-10-04
Abstract: Alloys containing magnesium, copper and silicon are produced by alloying copper and silicon to form a copper silicon alloy and alloying this alloy with magnesium or a copper-magnesium alloy, the copper-silicon alloy being preferably added to molten copper-magnesium alloy.  The copper-silicon and copper-magnesium alloys should have melting-points substantially lower than the melting-points of copper and magnesium respectively, e.g. by use of the eutectic binary alloys.  The ternary alloy produced may then be alloyed with ferro-silicon or with ferro-silicon containing a small amount of copper to form an alloy for addition to molten iron or steel.  A part or all of the silicon used to form the original copper-silicon alloy may be replaced by ferro-silicon, the resulting copper-magnesium-silicon alloy containing a substantial amount but less than 20 per cent of iron.  In this case the copper-silicon-iron alloy should have a melting-point substantially lower than that of the ferro-silicon used.  The copper-magnesium-silicon alloy may contain Mg 10-55 per cent, Cu 12-50 per cent and Si 4-65 per cent, Fe, if present, being less than 20 per cent, e.g. 3-15 per cent.
