Title: Fluid flow control valve
IPC: B60T13/14
Filed: 1961-07-04
Abstract: 942,299. Valves; fluid-pressure brakes. D.B.A. S.A. July 4, 1961 [July 8, 1960], No. 24136/61. Headings F2F and F2V. A control valve for a fluid braking system, comprises a valve member 24 adapted to cooperate with a seat 36 between an inlet chamber 38 and a working chamber 32, and also with a second valve seat 30 between the working chamber and an exhaust port 34. The seat 30 is formed on the end of an actuating member 20 having a piston part 44 forming a movable wall of a reaction chamber 46 which has an inlet 50. The valve is operated through a spring 22 to close the chamber 32 from the exhaust 34 and open this chamber to the inlet whereby fluid flows to a motor. The inlet 50 is connected to a point between the outlet 33 of chamber 32 and the motor, preferably adjacent the motor, and this pressure acts on the piston 44 against a spring to reseat the valve 24 on its seat 36 and provide " feel." Such an arrangement allows a quick build up of pressure in the motor as opposed to a valve where the chambers 46 and 32 are the same and the pressure in the working chamber 32 acts directly on the piston member 44. The dimensions of the member 22 are chosen so that a valve is pressure balanced. In the brake system described, a pump supplies fluid to an accumulator through a pressure regulating valve, the accumulator being connected to the inlet 39. The outlet 33 leads to four motors being the brake cylinders at each wheel. Specification 692,969 is referred to.

Abstract: 634,846. Di-electric heating. GENERAL ELECTRIC CO., Ltd., CROCKER, C. H., and HARRIS, E. S. Aug. 14, 1946, No. 24160. [Class 39 (iii)] [Also in Groups XXXV and XL (c)] A method of manufacturing an insulated electric coil, e.g. a flat spiral loop-aerial coil, comprises winding a conductor covered in thermo-plastic material on a former and heating the thermo-plastic material by di-electric heating to the point of plasticity to form a rigid coil on cooling. As shown in the figure, the wire which may be covered with polyvinyl chloride is wound on a jig comprising two conductive plates 1 and 2 of non- magnetic material, an insulating cylindrical member 4 being bolted to the circular plate I and the annular plate 2 being pressed against the winding 14 by the springs 12 which are mounted on bolts 11 secured to the member 4, the springs bearing against a disc 9 secured to the disc 2 by bolts 7 enclosed in pillars 10. A source of high-frequency electric oscillations is connected to the plates 1 and 2 which constitute the plates of a condenser the di-electric of which is constituted by the covering of the wire and the resultant di-electric heating fuses the covering so that on cooling a rigid coil is obtained which may be removed from the jig. In a modification the plates 1 and 2 may be made of any suitable material and the opposing faces plated with metal of good electrical conductivity. According to the Provisional Specification the coils manufactured as above may be employed as field or armature coils for rotary machines or as induction coils.

Title: Improvements in or relating to driving and "free wheel" mechanism or couplings for shafts and the like
IPC: F16D41/22
Filed: 1931-08-28
Abstract: 373,027. Ratchet clutches. SHARMAN, C. P., 17, Northumberland Road, Sheffield. Aug. 28, 1931, No. 24202. [Class 80 (ii).] In ratchet clutches for motor cars &c. of the kind in which the parts may be locked together for drive in both directions, screw threads in a casing 1 secured to a driving disc 2 on the shaft A engage similar threads on a ring 3 carrying teeth 3a adapted to engage teeth 5a on a sleeve 5 on the driven shaft 5 when the shaft A tends to overrun the shaft B. The movement of the ring 3 is ensured by the engagement with its interior of a spring 14, Fig. 6, secured to a sleeve 13 splined to the shaft B, the spring tending to expand during the driving movement of the ring 3 and to contract when the shaft B overruns. To secure the two-direction lock, a plate 10, spring- pressed against or secured to an axially movable control collar 9, carries bevel-ended pins 11 engaging loose pins 12 which can thus be pressed out to maintain the engagement of the clutch teeth, but will not return under reactive pressure until the pins 11 are withdrawn. The splines B<1>, Fig. 6, on which the sleeve 13 slides may be recessed at B<2> oppositely to the direction of drive, so that the sleeve becomes a baulking member, preventing clutch engagement until the speeds of the driving and driven shafts equalize. The control collar 9 may be interconnected by a lost-motion linkage with the main clutch pedal, so that the two-way drive may be inoperative when the main clutch is disengaged during gear changing and is reestablished when the main clutch is re-engaged.

Title: Weighing scale pendulums
IPC: G01G1/00
Filed: 1946-08-17
Abstract: 625,830. Weighing apparatus. WILLIAMS, L. S., and TOLEDO SCALE CO. Aug. 17, 1946, No. 24531. [Class 143] Pendulum - weight apparatus. - In a weighing-scale pendulum having a variable power arm designed to secure a linear indication and provided with a straight track 28 along which a weight is movable to change the capacity, the length of the power arm is substantially a maximum when the track 28 is vertical. By suitably locating the track 28 so orientated, movement of the weight along it to change the capacity is without effect on the linearity which, in the construction shown, is itself independently adjustable by moving a further weight along a second track 35 set at an angle to the first. The pendulum shown is one of a pair symmetrically disposed on either side of a frame standard having on each side a guide 5 for the - fulcrum ribbons 9 and sectors 8 of the pendulums. The power sector 13 is eccentric to the fulcrum sector 8, its centre 27 being off-set from the centre 19 of the fulcrum sectors and the track 28 being disposed at right angles to the line of centres 19-27. Power ribbons 12 connect the power sectors of the two pendulums to a cross-head 10 on the load rod 11, and upward translation of the pendulum under load is transmitted to a rotatable indicator by connections to the turning centres 19. A capacity weight 30 is adjustable along the track 28 and is secured in adjusted position by bolts 32 threading into a cylindrical nut 34 slidable along a bore at the bottom of a slot in the face of the track. The second track 35 is formed as a bracket mounted on the capacity weight 30 itself by the bolts 32, and the linearity adjustment weight 38 is secured in adjusted position along it by a U-clip 37 and bolt 41. The weight 37 can also be shifted vertically to effect small capacity adjustment. A modified form, Fig. V (not shown), designed for a low. initial pull has the fulcrum and power sectors extended downwardly, and the pendulum is allowed to swing further inwards towards the sector guide standard. The track 28 is then no longer vertical at zero, but is still at rightangles to the line of centres 19-27. In another form, Fig. VII (not shown), the tracks 28 and 35 are threaded rods set in the pendulum casting at an appropriate angle and carrying the adjustable capacity and linearity weights. The Specification describes in detail, with graphical illustration, the effect on the scale characteristic of adjusting the two weights, and explains the considerations determining the location of the track 28 and the angle at which the track 35 is set to it.

[Also in Group XXXVII] In an automatic temperature-control system for an electric hot-plate in which the energization of the heater element is controlled by contacts adjusted by a measuring bulb touching the vessel on the hot-plate as in Specification 800,773, [Group XI], the co-operating electric contact is oscillated by an independent bimetallic interrupter to effect proportional control. The bulb 14 touches a cooking vessel 12 when placed on the hot-plate 10 and by moving the diaphragm 22 via capillary 16 causes the spring-loaded contact arm 48 to move downwards as the temperature rises. The diaphragm 22 is mounted on an adjusting screw 28 for manual datum setting. The screw 28 also carries cam 70 which opens a pair of contacts in the supply line when the screw is set for the minimum temperature. The contact 50 on arm 48 co-operates with a contact 62 on a pivoted spring-loaded arm 58. The arm 58 is reciprocated via a push-rod 66 by abi-metallic strip 36 which has a heater 44 in series with self-interrupting contacts 40 so that it oscillates continuously. The on-off ratio of the main contacts 50, 62, is thus made proportional to the temperature deviation.
