Title: Improvements in flexible diaphragms
Inventor: PRICE RICHARD HECTOR
IPC: F16J3/02
Filed: 1950-02-03
Abstract: 696,545. Valve closure members. SAUNDERS VALVE CO., Ltd. Jan. 24, 1951 [Feb. 3, 1950; June 29, 1950], Nos. 2878/50 and 16278/50. Class 135 A flexible diaphragm of rubber &c. and suitable for use in a diaphragm valve has a facing of a material more inert chemically than natural or synthetic rubber &c. and formed with an integral projection or projections by which it is mechanically interlocked with the diaphragm. The facing may be of a polymerized halogen-substituted ethylene such as polymerized tetra-fluoroethylene. In Fig. 1 the facing 4 has integral lugs 5 which receive metal pins 6, whilst in another arrangement laces integral with the facing are knotted together after passing through holes in the diaphragm. Fig. 4 illustrates a method of attachment consisting in clamping under a metal cap 10 the ends of lugs 9 which are apertured for the passage of a stud 3 moulded into the diaphragm. The stud serves for the attachment of actuating means for the diaphragm as in Specification 434,665. As shown in Fig. 6, the facing has laces 11 or lugs 12 which are passed through a lower layer 1a and a reinforcement of the diaphragm and are then tied or bent over after which an upper layer 1b is applied and the whole subsequently cured. Fig. 7 illustrates the use of dovetail or T-section lugs which are embedded in the diaphragm before it is cured. Alternatively, the facing may have an upstanding cylindrical lug which is embedded in a central boss of the diaphragm before curing. In this case, holes are formed in the lug and become filled by the material of the diaphragm during curing. Another method consists in embedding in a central boss on the diaphragm a boss integral with the facing and then curing. A stud is embedded in the boss of the facing. Fig. 12 illustrates the use of a facing consisting initially of two parallel discs interconnected by an integral boss 19 of small diameter and cut from solid bar. One of the discs, 4, serves as the facing proper whilst the other is cut to form radial fingers, alternate ones, 23, of which have holes which are passed over a stud 3 whilst the others, 22, extend radially within the material of the diaphragm. A rubberized fabric reinforcing piece 26a passed over the stud has radial arms 26b which pass through holes 24 in the fingers 22. Other holes 24 are formed in the fingers 22 and 23 into which the material of the diaphragm flows during curing. Specifications 585,607; 657,324 and 685,935 also are referred to.

Title: Improvements in and relating to alternating current frequency changing apparatus
Inventor: MARTIN ALBERT EDWARD
IPC: H02M5/32
Filed: 1956-01-30
Abstract: 838,215. Infra-red gas analysers. GRUBB PARSONS & CO. Ltd., Sir H. Jan. 18, 1957 [Jan. 30, 1956], No. 2937/56. Class 40 (3). [Also in Group XXXV] So that an A.C. signal of relatively low frequency f (e.g. 10 c/s.) may operate instruments designed for a standard frequency (e.g. 50 c/s.), it is converted to a frequency F Œ f by applying constant-amplitude current of frequency F to the driving coil B of a vibratory interrupter A having fixed contacts C, D, and the signal between terminal E on the vibrator and rnid point F of primary winding of transformer T connected to contacts C, D. One of frequencies F Œ f can then be filtered from the secondary winding at terminals G, H. In a modification two interrupters may be used. Constant-amplitude currents of frequencies F and f are applied to the first, and the output of frequency F Œ f is then applied (through an amplifier if necessary) to the second, together with a signal of frequency f to give an output of F Œ f Œ f from which frequency F can be filtered. The constant-amplitude currents of frequencies F and f may be obtained respectively from the mains supply and a generator driven with the signal generator. If the signal is from a gas analyser, the latter current may be obtained from a photo-electric cell receiving light from a lamp interrupted by a sector driven synchronously with that in the instrument. The first converter may be omitted if a frequency F + f can be derived directly, e.g. from a generator driven simultaneously with the sector.

Abstract: 780,384. Container-filling machines. AUTOPACK, Ltd. Feb. 2, 1956 [Feb. 3, 1955], No. 3188/55. Class 94(1). Containers 5 are moved in succession over a table 6 by an intermittently-rotatable feeder 4 and positioned in turn on a platform 7 which is elevated by an electromagnet 8 to lift each container into sealing engagement with an annular resilient pad 9 surrounding the outlet of a shoot 3 through which a charge of powdered material is fed from automatic weighing mechanism of known type. The space between the pad and the shoot communicates through a filter 12 with a chamber 11 which is connected by passages 16 and 17 to a suction port 20 controlled by a piston 19 working in a cylinder 18. The piston is moved downwardly during the filling operation so that air is sucked out of the container to assist the flow of material from the shoot. At the end of the filling operation, the piston is moved upwardly to cut off the suction and deliver a blast of air through the filter to dislodge material adhering thereto. The movements of the piston and the opening and closing of a valve 21 in the shoot outlet are controlled by the movement of the feeder 4. The discharge of material from the weighing mechanism is dependent on the correct positioning of a container in engagement with the pad 9. The shoot and associated parts may be raised or lowered to suit containers of different sizes.
