Abstract: 295,336. Drohnn, P. Aug. 9, 1927, [Convention date]. Balls.-In a football wherein a reinforcing cover is inserted between the bladder and the outer case, the reinforcing cover consists of a number of fabric layers secured together by adhesive after the manner of ply wood so that the threads and joints in the successive layers run in different directions thereby producing a structure of uniform strength. The pieces of material are stuck on to or round a spherically. inflated bladder with the threads and joints in the adjacent layers intersecting. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a method of construction of the ball wherein two linen hemispheres are formed by passing the fabric round a wooden sphere, and the two hemispheres are secured to the inflated bladder by adhesive together with an equatorial strip, or the two hemispheres and the strip are places over the bladder and secured together by an adhesive. The two hemispheres of the next layer are applied so that their seam is at right angles to the seam of the first layer and other layers may be similarly added, the threads and seams of each layer being arranged to cross the threads and seams of the other layers. This subjectmatter does not appear in the Specification as accepted.

Title: Electrical connector
IPC: H01R13/193
Filed: 1972-06-26
Abstract: 1392738 Two-part couplings A LOUIS 26 June 1972 [24 June 1971 6 June 1972] 29855/72 Heading H2E An electrical plug has at least two metal pins for insertion in apertured conducting members of an electrical socket so as to provide electrical connection between the plug and the socket, each pin comprising two parts one of which parts can swivel about swivel means on the other part adjacent the end of the pin which is engageable with the apertured member of the socket means. A loading means, e.g. a cam, is provided for causing the swivelling part to move, thereby to increase the pressure between the pin and the apertured member, so as to enable the normally acceptable current density to be appreciably increased without the pin becoming heated. Such pressure applied by, e.g. cam 8 and elongate contact member 3 against the inner wall of socket 19 is insufficient to prevent forceable separation of the plug and socket in an emergency. Electrical lead 6 is connected to contact pin 2 at 5, and lead 13 to socket 11 in hole 14, secured by screw 12. In another embodiment, the electric lead is connected to an electrically conductive portion 27 on cam 7 (see Fig. 8) which makes electrical contact with elongate contact member 3 only when lever 8 is in position for connection (Fig. 2). In another embodiment, Fig. 9, the cam 87 may comprise separate portions 7A, 7B and contain a fuse 28. In a further embodiment, the cam 7 may have peripheral teeth (26) (Fig. 7, not shown) to engage a toothed rack (25) on an external sleeve (22) such that when the sleeve is pushed over the cam the contact member 3 is swivelled into position.

Title: Improvements in lubricating systems
IPC: F16N39/02
Filed: 1919-12-04
Abstract: 161,232. Parsons, Sir C. A., Cook, S. S., and Douglas, L. M. Dec. 4, 1919. Fluid-actuated valves.-In a lubricating-system employing a single pump to pass oil through two or more coolers supplying bearings and sprayers respectively, as described in Specification 152,760, [Class 12 (iii), Lubricators &c.], the proportion of oil delivered to two branches is controlled by a valve responsive to pressure in the discharge from each cooler, so that an increased supply is delivered to a branch in which the pressure falls, means are also provided for by-passing a cooler which becomes choked. Oil from the pump enters at 7, Fig. 3, the casing of a double piston valve 5 controlling two outlets 8, 9 leading to coolers 1, 2, and the two pistons are subjected to the pressure in the outlets of the coolers through pipes 10, 11 so as to control the openings 8, 9, which are preferably of such form as to give a. large movement to the valve. The shape and size of the openings is determined by diaphragms 12, 13. By-pass openings 14 in the piston register with grooves 16 so placed that at the extreme positions of the valve, which are determined by stops 18, the bypass can deliver the total quantity of oil required by the system whose cooler is choked. The valve may be fitted with light springs to bring it to the normal position. An additional by-pass, coming into operation before the by-pass 14, 16, may be provided by a pipe 20 allowing oil from the outlet of the cooler to pass into that of the other after a certain movement of the valve in one direction. This by-pass can be provided in connection with one or both coolers. In a modification, the openings 8, 9 are replaced by slots in the inner ends of the pistons communicating with annular channels in the casing 6 connected to pipes leading to the coolers, and by-pass grooves in the pistons put these channels into communication with the spaces at the ends of the casing. Fig. 5 shows a modification in which the whole of the oil passes through a primary cooler 1 and part of the oil through a second cooler 2, the remainder passing through an opening 7 to an outlet 8. Movement of the valve 3, 4 to the right, due to a fall in pressure at the outlet from the cooler 2, first restricts apertures 25 leading to the outlet 8 and so increases the flow through the cooler 2, and then uncovers a groove 26 admitting oil directly from the opening 7 to the system supplied by the cooler 2. A by-pass 29 may be added allowing a further supply to this system through passages 28, 29. One of the piston ends of the valve may be stepped, the annular spaces between the steps being connected to the atmosphere. A difference in pressure may be obtained by a spring acting on one end of the valve, or the valve may be placed vertically and made of sufficient weight to cause the necessary difference in pressure.
