Title: Automatic control of mine car loading and feed conveyor
Inventor: HATHAWAY RICHARD
IPC: B65G67/00
Filed: 1965-02-09
Abstract: 1,086,905. Loading mine cars. QUALTER HALL & CO. (SALES) Ltd. April 5, 1966 [Feb. 9, 1965], No. 5582/65. Heading B8E. Apparatus for the automatic control of a mine car feed conveyer 14 and means for propropelling the cars 12, comprises magnetic car sensors 1 . . . 5 which control the conveyer 14 so as to reduce its speed when the number of cars to be filled is less than a predetermined number, and which with probes MP1 . . . MP3 control the conveyer 14 and the car propelling means so that these are stopped when the last car is full. The conveyer 14, which is a plate conveyer, is fed from a gate conveyer (not shown) and delivers coal to a shoot 16 terminating in a radial door 18. In operation, when the back end of a car being loaded is almost level with the bottom lip of the shoot 16 the door 18 closes and the cars are moved forward until the next car reaches its loading position when the door is again opened. When the probe MP is operated the cars are moved forward by predetermined amounts until the car is full. When the end of the train is about three car lengths from the loading point the sensor 5 causes the conveyer 14 to operate at low speed allowing the gate conveyer to bunker coal on the conveyer 14, the last three cars being filled at the low rate. The sensor 4 stops movement of the cars with the last car at the loading position, and when the coal has built up in the shoot so that probe MP2 is operated the gate conveyer and the conveyer 14 are stopped. If further cars are then coupled to the loaded cars the sensor 3 is operated to start automatic operation of the car propelling means. The probe MP2 is relieved and the conveyer 14 is started. The gate conveyer is only restarted when thickly bunkered coal moving on the conveyer 14 operates the probe MP3.

Abstract: 929,898. Thermo-electric devices. L. BOLKOW, [trading as BOLKOW-ENTWICKLUNGER KOMM.-GES.]. Feb. 16, 1961 [Feb. 19, 1960], No. 5787/61. Class 37. [Also in Group XL (a)] Thermo-couples are heated by a plasma beam and the electric current produced is used to generate magnetic fields which guide or concentrate the beam. In Fig. 1 the conductors 1 forming one half of the thermo-couples are arranged generally spirally and extend from inner hot junctions 3 to external cold junctions 4, insulation 7 being provided between adjacent conductors. A similar series of conductors, Fig. 2 (not shown), arranged in anti-clockwise spirals is arranged beneath that of Fig. 1 and also extend from hot junctions 3 to cold junctions 4. Thus each thermo-couple circuit is generally circular with a hot junction 3 and a cold junction 4 at opposite ends of a diameter, and the current flowing in the circuit produces a magnetic field which assists in confining the plasma when the hot junction 3 are heated by the plasma. In another arrangement, Figs. 5 and 6 (not shown), each thermocouple element is in the form of a disc with a central aperture through which the plasma flows. The discs are joined together alternately at their inner and outer edges to form a number of thermocouples connected in series; the plasma itself forms the return conductor joining together the first and last discs.

Title: Improvements in the frequency adjustment of piezo-electric elements
IPC: H03H3/04
Filed: 1945-03-12
Abstract: 589,108. Fiezo - electric crystals. GENERAL ELECTRIC CO., Ltd., and ROLLIN, L. March 12, 1945, No. 6131. [Class 40 (v)] The frequency of vibration of a piezo-electric element is finally reduced to the required value by subliming non-conducting material on to it. The piezo-electric element 1, previously trimmed to vibrate within .005 per cent above its required frequency, is mounted, together with its necessary electrodes and leads 3, 4, on a glass pinch 2 within an evacuable chamber 7, 8, 9. Leads 3, 4 are connected to an exciting oscillator 26 whose output, at the frequency of the element, is connected to a mixer 27, also fed from an oscillator 28 of known frequency. The output of the mixer is then fed to a frequency-meter 29 which indicates the resulting beat frequencies. The chamber is evacuated by means of backing-pump 18 and oil-diffusion pumps 17, 10, the residual gas being removed by glow discharge effected by a high voltage field across the plates 7, 9 fed from secondary of transformer 23. Energy is then fed from transformer 19 to conducting pillars 11, 15 so producing heating, by eddy-current action or otherwise, of a tungsten trough 16 which contains subliming non-conducting material (e.g. magnesium chloride). This heating is continued until the deposit on the element reduces its frequency of vibration as indicated by the meter 29 to the required value, or to a value differing slightly from the required value by an amount depending on the conditions in which the element is to be used. The element assembly 1 to 4 is then removed and when it has to operate in a vacuum is then sealed into its envelope in the usual manner. The element may be sealed into its envelope and the latter evacuated prior to the subliming process, in which case the non-conducting material is contained within a metal pellet and applied in the manner of gettering in vacuum tubes. Calcium fluoride mav be used in this case. According to the Provisional Specification, the non-conducting material may be applied by other means ; for example, a solution in benzene of the material known as " Distrene " (Registered Trade Mark) may be painted on the crystal.

Abstract: 537,762. Thermionic valves. BRITISH THOMSONHOUSTON CO., Ltd. April 5, 1940, No. 6190. Convention date, April 7, 1939. [Class 39 (i)] [Also in Group. XXII] In a thermionic valve with a metal envelope 10 which is closed by a metal header 11 carrying the electrode structure, the joint between the envelope 10 and header is used before it is sealed as the means for evacuation of the valve. The lower end of the envelope is coned and the header has a corresponding flange 27 formed as a trough in which a ring of solder 33 is placed ; the two parts are mounted in a tube 30 for evacuation and are thereafter moved together, the joint being heated to effect the sealing. The solder may be attached to the coned end of the envelope instead of using the ring 33. The heating is obtained by applying alternating current to a plate 43 arranged in a centring tube 35 drawn on the header; this plate is of tantalum coated on one or both sides with barium or strontium oxide, which coating after sealing is used as the getter. The plate may be inclined to prevent the getter vapour entering the envelope. The tube 35 has a key way 36 for ensuring correct position in the valve socket, and acts as a shield between the anode and grid leads. Specification 503,076 is referred to.

Filed: 1952-03-11
Abstract: 718,984. Thermal switches; switches held set and freed mechanically. SQUARE D CO. March 11, 1952 [March 24, 1951], No. 6271/52. Class 38(5) The movable contact 9 of a switch is carried by an arm having a rigid portion 7 and a flexible portion 8 and carried by a bimetal strip 6 secured to a terminal 3. The strip 6 and arm 7 are inherently biased to hold contact 9 in engagement with a fixed contact 11. The arm 7 is embraced by the arms of a U-shaped resilient member 23, the position of the arms of which is adjustable by a screw 29 engaging a member 28 bearing on the convex bight of member 23. The contacts are manually opened by moving the dolly 18 counterclockwise from the Fig. 1 position to cause a cam 17 thereon to depress an armature 16 carried by the bimetal. Contact separation is delayed by projections 25 on the arms of member 23 until the flexible portion 8 becomes sufficiently stressed to overcome the pressure of arms 23, when the contacts snap open, the arms 23 restoring to hold the contacts open. Reverse movement of the dolly pushes a cam 22 between the ends 24 of the arms and releases the arm 7 which snaps to its closed position. The contacts are also automatically opened on a moderate prolonged overload by downward deflection of the bimetal strip 6 and on severe overload by the attraction of armature 16 by a magnetic flux in a member 27, of which member 28 forms part. In either case, the contacts are reclosed by hand. The member 23 is embraced by an ambient temperature compensating bimetal 26.
