Patent GB-758460-A (GB)
Title: Improvements in and relating to mine winders
Inventor: DOLAN HARRY
IPC: B66D5/26
Filed: 1953-11-10
Abstract: 758,460. Mine winder. ENGLISH ELECTRIC CO., Ltd. Nov. 5, 1954 [Nov. 10, 1953], No. 31085/53. Class 78 (5). In a mine winder of the kind having two minecages (or one cage and a counter-weight), control means are arranged to cut off the power to the winding engine when the ascending cage reaches a predetermined position and to cause rapid application of the brakes whereby to bring the ascending cage to rest just above the keps and means are provided for then automatically and momentarily releasing the brakes so as to allow the cage to move in a downward direction and to land on the keps, and for then automatically and momentarily releasing the brakes so as to allow any slack rope above that cage to be taken up. As shown, brake 10 is applied through pivoted brake lever 12, the latter being weighted at 13 and positioned by brake engine 14, the oil pressure in which is governed by the position of valve 15, which valve has its operating rod 23 positioned by lever 21 governed by solenoid SBS, and also positioned by the oil pressure in feedback relay 25. As the cage approaches bank level, it trips a track switch to cut out the winder motor and to de-energize solenoid SBS. The subsequent positions of valve 15 are then governed by the fall of lever 21 and the fall of pressure in relay 25, the fall of pressure in relay 27 additionally making double contacts BRLS1 and BRLS2. Thus the cage is brought to a halt above the keps; then the brakes are released to allow the cage to lower itself upon the keps; and the said lowering of the cage on to the keps operates a keps switch to bring the cage to rest upon the keps and subsequently to release and re-apply the brakes so as to permit any accumulated slack caused by the sinking on to the keps to be taken up by reason of the unbalanced portion of the rope.

Filed: 1950-12-21
Abstract: 693,778. Weighing-apparatus. AUTOPACK, Ltd., SMITH, A. R. LEE, G. A., and HOPKINS, C. J. Dec, 4, 1951 [Dec. 21, 1950], No. 31155/50. Class 143. In an automatic weighing machine for automatically weighing powdered and like material the weighing mechanism is enclosed in a casing and a fan a or other means introduces into thecasing through a filter f an air stream of pressure higher than atmospheric to obviate the intrusion and settling of dust on the mechanism. The fan may be driven by a belt c from an electric motor d actuating the control mechanism and may cool the motor. The air finally escapes to atmosphere through apertures in a partition of the casing after traversing the control mechanism. In place of the fan an external blower or supply of compressed air controlled by a valve in the casing may be used.

Filed: 1948-12-03
Abstract: N-Methyl-N1-benzhydryl piperazines having pronounced antihistaminic properties are obtained by treating excess of methyl piperazine with a benzhydryl halide in which the para-position of one of the phenyl groups may be substituted by chlorine, bromine or methyl and the para position of the other phenyl group may be substituted by chlorine or bromine.  According to the examples, methyl piperazine is treated with benzhydryl chlorides and p-substituted derivatives thereof to give N-methyl - N1 - benzhydryl piperazines, unsubstituted in the benzhydryl groups, or substituted in one para-position as above, in both para-positions by chlorine, or bromine, in one by chlorine and one by bromine, and in one by chlorine and one by methyl groups.  The products may be isolated by conversion to the quaternary salts of hydrochloric, hydrobromic sulphuric, phosphoric, lactic, malic, succinic and other non-toxic and non-oxidizing acids, and used as such.  Specifications 578,342 and 578,343 are referred to.

Abstract: 919,729. Confectionery. NATIONAL DAIRY PRODUCTS CORPORATION. Sept. 13, 1960 [Sept. 18, 1959], No. 31465/60. Class 28 (1). [Also in Group V] A mixture of sugar and syrup is heated until fluid and pumpable, most of the water is removed, and peanut meats are added while the temperature of the mixture is sufficient to plasticize the meats after which the mixture is deposited on a supporting surface and compressed into a layer which is thinner than the dimensions of the nut meats, the supporting surface travelling more rapidly than the rate at which the layer is formed to reduce the thickness of the layer which is then hardened. As shown, the mixture is heated in mixer 10 held at about 240 F. to form a mix whose solids content is approximately 92%, which is pumped to an evaporator 13 where it is heated to between 300 F. to 315 F. and the solids percentage goes up to 99.2%. This syrup is mixed with bicarbonate of soda and nut meats and is fed by a steam jacketed screw conveyer 22, which it leaves at about 290 F., to a heated hopper 25 whose outlet is limited by a steam heated steel roller 26. The syrupy mass is pressed into a layer thinner than the nut meats, which after pressing return to their original size, by the roller 26 and a conveyer belt 32 which travels more rapidly than the periphery of roller 26 and may be fibre glass coated with tetrafluorethylene. A scraper 36, e.g. edged or coated with tetrafluorethylene, removes any mixture adhering to roller 26 and deposits it on the layer 38. The layer 38 is cooled in a chamber 39 and then separates from belt 32 as it passes round roller 34 and breaks off in pieces suitable for packaging.

Title: Improvements in and relating to power factor correction arrangements for intermittently energized inductive electric loads
IPC: B23K11/24
Filed: 1945-11-28
Abstract: 637,644. Supply systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 28, 1945, No. 32174. Convention date, Nov. 29, 1944. Addition to 535,933 and 543,800. [Class 38 (iv)] [Also in Group XXXVII] In a supply system for a resistance welding transformer 1 or other intermittently energized inductive load, switching means are provided for connecting power factor correction capacitors 23 to the supply circuit 2 during the periods of energization of the load. The capacitors are charged through rectifier 28 in the off load periods and, upon energization of the load circuit, the switching means operates to connect them to the supply circuit at the moment the supply voltage wave is passing through its maximum value. Transformer 1 is supplied through ignitrons 3, 4 under the control of a timer 18 which, in addition to controlling the excitation circuits of these tubes, also controls, over transformer 52, the excitation circuits of ignitrons 26, 27 by which the capacitors are connected to the supply circuit. Ignitrons 26, 27, which have holding anodes 32, are fired 'by the discharge of condensers 33 into the ignition circuits over thyratrons 34, the control grid circuits of which include resistors 45, 48, 49 across which components of control voltage are developed. Resistor 48 provides a hold-off voltage derived from a supply circuit 42, transformer 58 and anode 60 of a rectifier 54. whilst the other anode of the rectifier which is fed from the timercontrolled transformer 52 provides in the resistor 49 a turnon voltage. This last voltage prepares the thyratrons for conduction, which occurs when the resistors 45 are energized by a peaking transformer 47. This transformer is supplied from circuit 42 through a phase-shifter 64-47 so adjusted that the thyratrons 34 conduct when the voltage wave of circuit 2 is passing through a maximum. Over-voltage protection of capacitors 23 is provided by a spark-gap 81 which, upon breaking down, energizes a trip coil 83 on a supply circuit-breaker 84.
