Title: Improvements in or relating to valves
IPC: G05D16/10
Filed: 1932-10-07
Abstract: 390,739. Combined pressure-reducing and stop valves. HILL, A., White Row, Trusthorpe, near Mablethorpe, Lincolnshire. Oct. 7, 1932, No. 27891. [Class 135.] In a combined pressure-reducing and shutoff valve of the kind having an outlet 18 controlled by a piston 4 which is subject at one end to outlet pressure and has at the other end an extension forming a valve member 28 which controls the inlet 6, adjustable means are provided for yieldingly shifting the piston to close the outlet. In one form, Fig. 1, these means take the form of a spring 35 the upper abutment 36 of which can be adjusted by means of a screwed spindle 37 either to alter the loading effort or to bear down on the piston so as to close the valve completely. Axial movement of the spindle 37 is prevented by a shoulder 42 and a spring 43 disposed between the hand-wheel 46 and a ball thrust bearing mounted on the cover 39. The latter has depending rods 38 which prevent rotation of the abutment 36 and also of the piston 4. A liner 23 in which the piston 4 slides is secured against a shoulder 24 by means of a ring nut 25 and has a series of slots 27 of graduated size providing communication between an enlarged chamber 5 and a channel 17. The top of the piston 4 is subject to outlet pressure by means of a passage 22. The valve member 28 is of stepped conical formation to provide several lines of contact with its seating and is secured to the piston 4 by means of a screw bolt 29. Its seat member 9 is secured in place against a shoulder 7 by means of a ring nut 10. The valve 28 is practically fully open whilst the piston acts as a reducing valve. In the form shown in Fig. 3, the adjustable spring means are replaced by a weighted lever system comprising a weight 63 adjustable on an external lever 61 which is secured to a spindle 52. The latter also has secured to it a short yoke-shaped arm 51, the free end of which is provided with a roller which engages a slotted extension 49 of the piston. In this form, the means for closing the valve positively are independent of the yielding means, the screw member 37 moving axially in a nut 66 fixed in a box 68 of the cover 65 so as to bear directly on the extension 49. Alternative forms of bearings for the spindle 52 are shown and described. In a slight modification, the seat 9 rests above a shoulder in the chamber 5, being inserted therein through a lateral opening, for which a cover is provided.

Title: Vehicle tyre vulcanising press
IPC: B29D30/06
Filed: 1959-08-17
Abstract: 883,775. Vulcanizing presses for tyres. MACBETH, C. Aug. 5, 1960 [Aug. 17, 1959], No. 28001/59. Class 87(2). A press of the kind described in Specification 728,160 that vulcanizes two tyres simultaneously between superposed mould holders 11, 12, 13 has an improved operating mechanism. As shown in Fig. 1 to remove the tyres from the moulds, a crank 22 is rotated by a motor 26 causing the crank pin 23 to operate a toggle linkage 14, 15 (on each side of the press) thus initiating the opening movement of the holders. At the same time cam tracks 27, 28 impart vertical movements to pivots 17, 19 which through arms 16, 18 act as the pivots for the intermediate and top holders 12, 13, respectively. The pivot 19 is raised at twice the rate of movement of the pivot 17. During this movement, the intermediate holder is kept parallel with the lower holder by a cam roller 36 engaging a slot 35. Continued movement of the toggle fully opens the top holder allowing the top tyre mould to be removed, the motor 26 being stopped at this point by a contact breaker. The motor is then restarted and a cam 34 cuts on a roller 33 and linkage 32, 31 to fully open the intermediate holder. In a modification, Fig. 2 (not shown), the cam 34 is formed integrally with the link 24 instead of being mounted on the crank disc.

Title: Improvements in or relating to tyre-inflating apparatus for road vehicles
IPC: B60S5/04
Filed: 1920-10-04
Abstract: 173,604. Barnfather, R. Oct. 4, 1920. Regulating and controlling compression.-Tyre inflators of the kind actuated by and attached to the road wheel of a vehicle so as to maintain the tyre inflated in case of a leak during running are provided with automatic cut out devices in which the pressure of the air displaces a spring- controlled member, the movement of which operates mechanically to neutralize the pumping action of the inflator when the desired pressure is reached. As shown, the pump cylinders a, b, Fig. 1 discharge compressed air into the flexible tube j, Fig. 2, which is connected to the tyrevalve through a union i which communicates through a tube h with a control cylinder g placed between the pump cylinders. When the air pressure exceeds a predetermined amount, the piston k of the control cylinder is forced outwards against the action of a spring k so as to engage an adjustable tappet l secured to the cross-bar of a U-shaped frame f, the free ends of which maintain the inlet valves m of the pump cylinders in an open position. On the air pressure falling, the piston returns into the control cylinder under the action of the spring and the frame is returned to its normal position by centrifugal force. The control cylinder may consist of the known pressure gauge in which the piston projects from the cylinder and is calibrated so as to indicate the pressure of the air within the cylinder. In a modification, the tappet b is maintained in contact with the piston of the control cylinder by springs fitted upon the arms of the frame f. The pump is actuated in known manner through cranks and gears d as described in Specification 29326/13. Specifications 12873/08 and 27316/13 also are referred to.

Filed: 1945-10-25
Abstract: 597,978. Electric indicating systems. FERRANTI, Ltd., TAYLOR, M. K., KNOWLES, A. D., and TOOTAL BROADHURST LEE CO., Ltd. Oct. 25, 1945, No. 28177. [Class 40 (i)] [Also in Groups XXXVI and XL] Relates to apparatus for measuring the physical state of material, and is particularly described with reference to the determination of the degree of dampness of cloth. The cloth is placed between the plates of a condenser 38 to vary its leakage resistance and thus the "Q" value of the tuned circuit 35, 38; a circuit 34, 37 tuned to a different frequency has a standard " Q " value, and an oscillator 10 alternately traverses two frequency ranges, each containing one of the resonant frequencies of circuits 34, 37 and 35, 38 ; these oscillations are applied to the tuned circuits to produce pulses dependent on the " Q " value of the circuits which are differentially combined to produce a current dependent on the dampness of the cloth. The oscillator 10 comprises a condenser 14 rotated through its range once for each opening and closing of switch 20 so as to produce two distinct sweeps of frequency for application to the tuned circuits 34, 37 and 35, 38. The modulations produced when the applied frequency coincides with the resonant frequency of either circuit are rectified at 42, amplified at 43, 51 and applied to transformer 52. A contact 59, operating in unison with switch 20, applies the rectified pulses from circuit 34, 37 in one sense and the rectified pulses from circuit 35, 38 in the opposite sense to a smoothing circuit 64, 65, 66 which thus delivers a current which is zero if the material has the correct degree of dampness and is positive or negative according as it is too dry or wet. Specifications 591,147, [Group XXXVI], and 597,979, [Group XXXV], are referred to.
