Title: A method joining superposed fabrics and the products of such method
IPC: D04H13/00
Filed: 1966-04-15
Abstract: 1,091,068. Printing blankets. W. R. GRACE & CO. April 15, 1966 [Nov. 19, 1965], No. 16691/66. Heading B6C. [Also in Division F2] In a screen printing machine in which material to be printed is temporarily adhered to an intermittently movable endless fabric printing blanket 10 and in which the intermittent movement is effected by clamping members systematically gripping the longitudinal edges of the blanket, each such blanket edge has an edge piece 14 of fabric riveted thereto the edge pieces providing the gripping surfaces for the clamping members. The rivets are of a flexible polymeric material preferably a plasticized, cured epoxy resin. The rollers 11 around which the blanket passes may be stepped to compensate for the difference in level between the bottom of the blanket and the bottom of the edge fabric. Alternatively the edge fabric and/or blanket may be flanged or skived at an angle. In a further embodiment the endless edge pieces 14 are replaced by strips riveted to the blanket edges at locations engageable by the clamping members. In a method of making the composite structure, pieces of fabric 14 of the same material as the blanket 10 were placed alongside and partly beneath each blanket edge. Holes were then drilled through the superimposed material and, whilst held by masking tape, which also blocked the bottom of the holes, riveting was effected by pouring into the holes a self-curing composition of epoxy resin.

Title: Improvements in and relating to thermionic apparatus
IPC: H01J17/04
Filed: 1928-06-11
Abstract: 294,168. British Thomson-Houston Co., Ltd., (Assignees of Schmidt, A.). July 19, 1927, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus. - Relates to thermionic apparatus having a cathode-heating element and an exciting electrode and consists in (1) having means connected between the heating-element and the exciting electrode for limiting the starting current of the heater, and which may comprise an impedance device for applying to the starting electrode a potential which is dependent on the current of the heating-element, and (2) in the case of a rectifier, filling the envelope with gas or vapour at a pressure below that at which the discharge becomes arc-like. The filling may be of mercury vapour or rare gases such as argon and neon. The cathode 6 may be coated with a highly-emissive material, e.g. barium or other alkaline-earth oxides, or rare-earth metals such as cerium. Current is supplied to the cathode heating-element 5 by a secondary winding 13 on a high-reactance transformer 10 provided with a three-legged core, and to the exciting electrodes 8 by a secondary winding 14 the centre of which is connected either to a centre tapping of the winding 13, as shown, or directly to the cathode 6. The current supplied to the heating-element before it has become heated is limited by the magnetic shunt effect of the cone leg on which the winding 14 is wound, and the extra flux in this leg when the current in the winding 13 is high at starting causes a comparatively high potential to be applied to the exciting electrodes. The middle leg of the transformer 10 may be provided with an air-gap, as shown in broken lines, to produce a sufficiently high reactance.

Title: Hydraulic speed-responsive governors
Inventor: FREEMAN FRANK GEORGE
IPC: G05D13/10
Filed: 1955-06-13
Abstract: 806,747. Fluid-pressure servomotor-control systems. LUCAS (INDUSTRIES) Ltd., J. June 4, 1956 [June 13, 1955]. Class 135. An hydraulic speed-responsive device comprises a body a having a chamber b therein with an outlet z, a rotary body e contained in the chamber and having a passage h in communication with an inlet c in the body and a centrifugally operated valve s carried by the rotary body for controlling the rate of flow of liquid from the passage h in to the chamber b. The rotary body consists of a disc c secured to an engine-driven shaft f. Attached to the disc e is another disc n having a recess flanked on one side by a diaphragm o. The recess is in communication with the passage h by means of a small orifice q. A centrifugal mass t containing a valve closure member s is attached to a T-shaped arm u secured to the disc e by spring hinge blades v. The arm u is also attached to the diaphragm o by a stem x. A weight y is mounted on the disc e to balance the centrifugal mass t. At low speeds motive fluid from an engine-driven pump passes through passage c, a restriction d, passages m, i and h and acts on the diaphragm o, thereby holding the valve closure member s away from the outlet r, allowing fluid to flow freely from passage h into the chamber b. With increasing speed the mass t progressively moves the closure member s towards the outlet r causing an increase in pressure in the passages downstream of the orifice d. These pressure variations are sensed by a diaphragm 6 which acts on a hinged valve 10 controlling a vent 11 from a cylinder 12. The cylinder contains a piston 13 acted on by motive fluid pressure upstream of the orifice d, through a passage 16. A restricted orifice 17 in the piston communicates between both ends of the cylinder. Movement of the piston to the right is controlled by the vent 11. The rod 14 attached to the piston controls a variable output fuel pump or a throttle or by-pass in the fuel supply line to the engine. The governor may also be employed for varying the adjustment of guide vanes in a turbine-type air compressor in response to variations of speed of an associated prime mover.

Abstract: 1,187,081. Container closures. M. B. STULL. 13 April, 1967 [15 Dec., 1966], No. 17050/67. Heading B8T. A dispensing closure for a container comprises an outer cap screwed on to an inner tube, the cap having at least one eccentrically-located dispensing passage through its top. In one form, a cap 12, Fig. 1, is in screw-threaded engagement 16, 18 with a tube 10 integral with a container, and has a single eccentrically-disposed arcuate hole 30 in its top. When the cap 12 is screwed down, the hole 30 is sealed by the top edge 24 of the tube 10. Vertical ribs (38, 40), Fig. 2 (not shown), on the tube 10 and cap 12 interengage to limit the angle through which the cap can be turned to unscrew it. A stopper 28 internal of the cap 12 has a helical thread 42 of progressively increasing depth through which the contents of the container flow to the hole 30 as the cap is unscrewed, thus controlling the rate of dispensing. Cylindrical surfaces 32, 26 on the cap and tube engage sealingly to prevent dispensed product reaching the ribs (38, 40) &c. In a modification of this form, Fig. 7 (not shown), the stopper 28 is omitted. The cap 12 &c. is made of plastics. The tube 10 having a stepped bore 20, 22 may alternatively be a screw &c. cap for application to a container. In another form, a cap 54, Fig. 3, with three eccentric arcuate holes (60, 62, 64), Fig. 4 (not shown), in its top, has an inwardly-directed triangular lug 72 on its inside engaged with a helical thread 70 around a tube 46. An inwardly-directed lug 74 within the cap 54 slides over a helical cam track 76 around the tube 46 as the cap is unscrewed. An outwardly-directed lug 80 on the cap 54 similarly slides over a helical track 78 surrounding and spaced from the tube 46. The lug 80 has a pointer (82), Fig. 4 (not shown), which moves over indicia (84) along the top of the helical track 78 to show how far the cap 54 has been unscrewed. A stop 88 at the adjoined ends of the helical track 78 is engaged by the lug 80 to limit rotation of the cap 54 in both the screwing-up and unscrewing directions. A tapered stopper 58 seals the end of the tube 46. In a modification of this form, a cap (92), Fig. 5 (not shown), has a top surface (110) which is planar, is inclined to the plane of rotation of the cap, and has a single dispensing hole (106). A pointer (94) at the base of the cap does not slide over a helical cam track, but coacts with indicia (96) surrounding the cap tube (100) to show the extent to which the cap has been unscrewed. A stopper (112) in the cap (92), sealing the end of the tube (100), has a stepped configuration (114) to control the speed of dispensing proportionally with the unscrewing of the cap.

Abstract: 1,057,912. Automatic process control. H. EICKEN. April 24, 1964 [April 26, 1963], No. 17186/64. Heading G3R. The quantity of liquid taken up by a material during continuous processing is maintained constant by automatically controlling the pressure of rollers squeezing the material in dependence on the electrical resistance of the material after squeezing. As applied to warp thread sizing, the threads are passed to the squeeze rollers through an aqueous solution the concentration of which is maintained constant automatically. The moisture content of the treated threads is maintained constant by automatic control of thread speed. If the speed of the threads is reduced, for example to mend broken threads, change in the amount of size taken up is avoided by automatically controlling the pressure of the squeeze rollers, e. g. through a hydraulic device, in dependence on the electrical resistance of the thread after squeezing.
