Title: Improvements in or relating to loading machines for use in mining, quarrying and forlike purposes
IPC: E21F13/06
Filed: 1931-10-01
Abstract: 386,373. Endless-chain mine conveyers. BRITISH JEFFREY-DIAMOND, Ltd., Stennard Works, Wakefield, Yorkshire.-(Jeffrey Manufacturing Co. ; Columbus, Ohio, U.S.A.) Oct. 1, 1931, No. 27380. [Classes 78 (i) and 78 (iv).] Relates to mining and quarrying machines for gathering material lying in an elongated pile and loading it on to a delivery conveyer, in which a gathering conveyer, comprising a frame carrying sprockets for driving an endless chain supporting scraper flights for feeding the material to the delivery conveyer, is moved bodily parallel to the delivery conveyer by a cable passing round a winding drum on the frame. According to the invention, the gathering conveyer 10 is moved relatively to the delivery conveyer 138 by a cable 81, anchored to the frame at 95 and passing round a sheave 156 on a roof jack 157 to a winding drum at 50, the conveyer 10 being maintained perpendicular to the conveyer 138 by a cable 111 anchored at 158 and wound on a drum 106 controlled by a hand friction brake. The anchorage 95 and the drum are positioned at the top of the frame so that the tension of the cable 81 will tend to tilt the conveyer 10 about its longitudinal axis and enable the material to be gathered more effectively. The winding drum may be driven at two or more speeds by an electric motor through epicyclic gearing. The conveyer 10 is guided along rails associated with the conveyer 138 by a vertical V-shaped plate, the rails comprising a number of removable abutting sections. The drum 106 may be mounted on either side of the conveyer 10 so as to enable the conveyer to gather material in a reverse direction of travel, and be used on either side of, the conveyer 138. Specification 364,118 is referred to.

Title: Process for the preparation of triphosphoric esters of oxythiamine
Filed: 1950-11-09
Abstract: The invention comprises the triphosphoric ester of oxythiamine, of the formula <FORM:0697107/IV (b)/1> These compounds are obtained by treating the dihydrochloride of oxythiamine with picric acid, reacting the dipicrate thus formed with orthophosphoric acid and precipitating the salt of formula <FORM:0697107/IV (b)/2> by adding acetone, melting the salt and reacting it with phosphoric anhydride and separating the compound by precipitation from an aqueous solution of the reaction product by the addition of acetone.  An example illustrates the process.

Filed: 1954-09-24
Abstract: 763,540. Batteries. HEDSTROM, B. E. Sept. 24, 1954 [Sept. 25, 1953], No. 27711/54. Class 53. The electrodes 1, 2 of an alkaline cell which may be a zinc-silver accumulator are separ. ated by one or more layers of pergamyn paper 5, 6 which may be in the form of a wrapping surrounding each electrode. To protect the paper from oxi. dation by the silver oxide electrode layers 3 of cotton cloth, glass cloth, glass fibres, asbestos paper, or woven plastics may be interposed between the electrode and pergamyn paper. When cotton cloth is used it may be pre-shrunk by being boiled in a solution of potassium hydroxide then washed and treated with boric acid to remove traces of the hydroxide. Crepe cloth may be used and may be in the form of a pocket enclosing the positive electrode as shown at 3 in Fig. 1. The lower ends of the electrodes and wrappings are sealed by a layer 7 of pitch &c. Several cells may be mounted to form a battery by means of a casing formed from a number of plates 9 projecting from a flexible plate 8, Fig. 2. The cells 10 are placed in the compartments so formed which are then closed by side and top plates which are cemented to the plates 9. Adjacent cells are connected by conductors passing through the plates 9 which are provided with external grooves extending downwards to receive the conductors and provide long current leakage paths. The conductors of adjacent cells are welded together at their lower ends and the grooves then sealed by cellulose solution and covered by a plastic plate which is cemented in position.

Title: Improvements in or relating to actuating mechanism for sliding gates
IPC: B66B13/08
Filed: 1949-11-01
Abstract: 677,087. Chain and rope gearing. MORLEY, R. E. Nov. 1, 1950 [Nov. 1, 1949], No. 27910/49. Class 80 (i). [Also in Group XXV] An endless chain or cable c which operates a pair of oppositely sliding gates respectively fastened to the. upper and lower runs, is tensioned by means of a jockey pulley h loaded by a combination of weight and spring. Weights f are suspended by means of a rod g from the pulley, and compression springs k are interposed between the weights and a fixed bar i. The springs are stressed initially by nuts g<SP>1</SP> on the free end of the rod. In a modification adapted to compensate for chain stretch, the bar is mounted freely on the rod but is prevented from moving upwardly by wedging mechanism, while the spring stress is adjusted by nuts located on the rod above the bar and below the weights respectively. Tensioning of the upper run. of the chain by the driving pulley, should the chain have stretched, causes the upper nut to descend into contact with the bar and to draw it sufficiently downwards to take up the stretch. When the lower run is subsequently tensioned by the driving pulley, the bar is held in its new position by the wedging mechanism.

Title: X-ray diffractometers
IPC: G01N23/207
Filed: 1967-06-16
Abstract: 1,146,089. X-ray diffractometers. PICKER CORP. 16 June, 1967 [16 June, 19661, No. 27988/67. Heading H5R. In an X-ray diffractometer one of a pair of electrical contacts is mounted to move with a motor-driven goniostat and the other is carried by another part of the diffractometer with which a collision might occur as a result of the movement of the goniostat, the contacts being so located that when a collision is about to occur the contacts touch one another and complete an electrical input circuit to a control device for the motor which is thereby stopped preventing the collision. Preferably one of the contacts is compressible and the control device operates to reverse the direction of the motor so that when the movement of the contacts towards each other has ceased, movement occurs to separate the contacts. The contacts may be bonded directly to the electrically conductive parts of the diffractometer by an electrically conductive adhesive, the two conductive parts being insulated from each other. In a preferred embodiment, Figs. 1 and 3, the diffractometer is fitted with several pairs of contacts 30a to 30p fitted to the goniostat 16 and those parts of the diffractometer, e.g. chi ring 18, collimator 24, detector 13 and X-ray source 20 with which its motion might bring it into collision. (Contacts 30g, 30c and 30k are visible on Fig. 1). Goniostat 16 is insulated from the remainder of the diffractometer by being mounted on a plastics washer or shim (Fig. 2, not shown) and these two effective portions of the diffractometer are wired into an electric control circuit as illustrated in Fig. 3. The tube housing 20, detector 13, input collimator 21 and output collimator 24 are earthed and goniostat 16 is connected via line 60 to power source L1 via line 61 which also connects to solenoid 55 which is connected to earth 56, and then via switch 58 and line 66 to solenoid 65 and power source L2. The four D.C. motors, which drive the apparatus, 40-43 and their control arrangements are wired in a D.C. circuit through reversing switches 51 and 52. When operating, if any pair of contacts 30a-30p touch, then L1 is earthed thus shorting out solenoid 55 which thus releases switch 58 which it normally holds open against spring 59 and thus L2 is effectively connected to earth 56 and solenoid 65 is energized to operate switches 51 and 52 to reverse the polarity and thus the direction of motion of the motors. The event is recorded via line 63 in the programme which has overall control of the operation. A conventional diffractometer may be modified to include the safety arrangement of the present invention by attaching appropriate, e.g. silver filled P.V.C., contacts to the parts of the diffractometer by a conductive resin and completing the necessary insulation, earthing, and other necessary wiring.

The parts of the tube around the outer end 51 of the reed can then be removed. During the sealing the reed stress may be reduced or this may be done as a subsequent operation. In a multipole unit (Fig. 10) one reed 30 can be common to two ser esconnected sealed contact units.

A common motor for each pair of wheels may be used in place of the individual motors. The hydraulic transmission may be replaced by electric transmission using electric generators in place of the pump 21 and electric motors in place of the hydraulic motors.
