Filed: 1958-02-26
Abstract: 844,087. Hauling railway wagons. ROSS ENGINEERS Ltd., and BARROW, L. W. Feb. 6, 1959 [Feb. 26, 1958], No. 6268/58. Addition to 766,505. Class 104 (2). The railway wagon hauling bogie carriage of the parent Specification has means to vary the position of the hauling or controlling member 11 according as to whether it is to engage a loose or screw-type coupling 18 or 17. In an alternative arrangement the railway wagon hauling bogie carriage of the parent Specification has two hauling and controlling members having hook attachments at different heights whereby either one or the other may be employed according to the type of coupling to be engaged, Figs. 4 and 5 (not shown). In the arrangement shown in Fig. 1 the hauling member 11 in the normal position is arranged to engage the lower shackle 19 of the screwtype coupling 17. If a loose-type coupling 18 is provided on the wagon 8 the hauling member 11 is lifted to engage the lower link 20 of such coupling. The device for lifting the hauling member 11 comprises, mounted on a spindle 21 on the bogie, an actuating lever 22 and an operating lever 23 which carries a roller 24 at its end. The operation of the actuating lever 22 is effected by contact with a pivotallymounted stop member 26 mounted between the bogie rail tracks 6. The stop member 26 is actuated through a pivoted linkage 27 by an electrically, pneumatically or hydraulicallyoperated remotely controlled thrust member 28. The lever 22 and associated members and the linkage 27 are returned to the normal position after operation by a counterweight 25 and a spring 29.

Title: Improvements in or relating to methods for crimping yarns
Inventor: MATTINGLY DENIS ALBERT EDWARD
IPC: D02G1/02
Filed: 1963-12-20
Abstract: At least two yarns are simultaneously crimped by passing them through a first stretch in which they pass around each other a predetermined number of times, heating the yarns whilst in their then twisted form to impart a first crimp thereto, separating the yarns, passing the resultant crimped yarns through a second stretch in which they pass around each other a predetermined number of times but in the opposite sense to the first such passing, heating the yarns whilst they are in the second stretch to set the yarns in their then oppositely twisted form, and separating into the final, double crimped yarns.  The number of twists on each stretch and the degree of heating at each stage may be such that the final product is a non-torque crimp yarn. The length of the two stretches and the twist therein may be different or similar.  Crimping may be effective by the apparatus described in the parent Specification.

Title: Improvements relating to asbestos
IPC: B03B5/28
Filed: 1927-03-08
Abstract: 291,864. Simon, Ltd., H., and Jolley, F. R. March 8, 1927. Asbestos.-In separating asbestos from the rock with which it is found, the crushed rock and fibre is worked into a suspension in water, the rock and heavy matter separating out during the working whilst the liquid containing the asbestos and light where it is brought to a quiescent matter is led off to a settling tank -condition, the asbestos then being removed and dried. In the apparatus shown, the crushed ore drops into a trough b provided with a screen c, Fig. 5, which directs the material to the sides of the trough. A worm d agitates the contents of the trough and the lighter asbestos is fed forward and through the pipe k to the settling tank m whilst the heavier material falls through a slot e and may be further separated by a grid f. A conveyer g carries the material across the grid f and delivers any material which has not passed through the grid to a trough h from which it is further fed by a worm to a trough j similar to trough b. The conveyer g during its return movement delivers the heavy rock &c. to a discharge outlet i. The tank m has an inclined bottom and sides so that it increases in capacity away from the pipe n. The liquid is thus brought to a quiescent state and the asbestos is taken from the bottom of the tank by a conveyer o The water continuously circulates through the troughs b, j, tank m, and passage g, and an overflow chamber r and ball valves may be provided.

Title: Improvements in or relating to timing control systems
Inventor: PHILLIPS KENNETH RICHMOND
IPC: G04C23/16
Filed: 1966-02-15
Abstract: 1,123,243. Transistor switching circuits. SMITHS INDUSTRIES Ltd. 10 Feb., 1967 [15 Feb., 1966], No. 6689/66. Heading H3T. [Also in Divisions A4, G3 and H1] A timing circuit for use with heating devices such as an oven and boiling rings comprises a potentiometer 35, the wiper of which is driven by a synchronous motor at a speed of one revolution in twelve hours. A potentiometer 47 ganged to a switch 69 determines the instant that potentiometer 35 causes a transistor 41 to conduct and therefore the instant at which a transistor 48 ceases to conduct. When the transistor 48 ceases to conduct a transistor 68 conducts and a relay 71 switches on the heating device (not shown). After a predetermined time the wiper of potentiometer 35 disengages the potentiometer wire and the transistor 41 ceases to conduct so that the heating device is switched off. The transistor 68 also ceases to conduct when a transistor 58 conducts, the state of the latter being governed by a variable resistor 61 in series with a negative temperature coefficient resistor 55 located close to the heating device to enable the operating temperature of the heating device to be pre-set. The potentiometer 47 may be set so that the switch 69 is open, enabling manual instead of timed operation of the heating device since in this case the operation of the transistor 68 is independent of the transistors 41, 45, 48.

Title: Improvements relating to the prevention of overheating of laundry irons and other electrically heated appliances
IPC: H05B1/02
Filed: 1923-03-08
Abstract: 195,605. Simpson, C. A. April 1, 1922, [Convention date]. Electrically-tripped switches.-The supply of current to a heating apparatus such as a laundry iron is controlled by a thermostat and an electromagnetic cut-out operating upon excess current due to short-circuiting the heating element by the thermostat. The cut-out is reset manually, and during the resetting the circuit is opened at a, second switch by the operation of the resetting handle, the circuit being automatically closed at the second switch when the handle is released. Under normal conditions the heating coil 3, Fig. 5, is connected across the supply 2 through the operating coil 6 of a cut-out 4, 5, a switch 13 and a tumbler switch 28. When the temperature of the iron 1 reaches a predetermined value a bi-metallic thermostat 26 closes the contacts 19, 20 to short-circuit the heating coil 3. The increased current in the coil 6, Figs. 2, 3 and 5, causes its plunger 7 to open the switch 4, 5. The switch 4, 5 is reset by a handle 10 which operates a lever 12 connected to a switch 13 by a spring 14 so arranged that when the switch 4, 5 is closed with the handle 10 in its operated position the circuit of the coil 3 is open at the switch 13. When the handle 10 is released a spring 17 returns the lever 12 to its inoperative position and the switch 13 is closed to complete the circuit.

The valves are actuated in pairs 30, 42 or 32, 44 by a cam-shaft 86 having cam portions 90, 92 acting on depending stems from the valve members 58. The cam-shaft is operated by a lever 106 and is held by a spring detent 98, Fig. 5, in positions for actuating the motor in either direction or a neutral position. The valve members 58 are formed with a piston portion therefrom extending into a chamber in a removable cage 52, which also carries the valve seat 54, and a passage 66 allows the fluid pressure from one side of valve to act behind this piston to maintain the valve substantially balanced.
