Abstract: 1,130,519. Belt gearing. RAYBESTOSMANHATTON, Inc. 27 Jan., 1966 [23 Feb., 1965], No. 3803/56. Heading F2Q. [Also in Division B5] V-belts are made by building up a sleeve, Fig. 1, having a rubberized fabric back 12, and a superimposed cord layer 14, which is inverted (Fig. 2, not shown) before placing in the circular cavity 28, Fig. 5, of an injection mould so that the fabric back 12 is against the outer wall 44 thereof, the remaining part of the cavity (34) being generally V-shaped in cross-section and injecting rubber or a rubber-composition e.g. a fibre-loaded neoprene, e.g. via sprues 40, 42 causing the rubber to penetrate the cord layer 14 and fabric back 12 of the belt and filling the mould cavity 54 and then curing the belt. The sleeve forms the tension section of the belt and the injected rubber the compression section. The sleeve is preferably of rectangular crosssection, and the first part of the mould cavity (30, Fig. 3, not shown) conforms thereto. When building up the sleeve, a thin layer of tie-rubber 18 is preferably applied over the cord layer 14. The sleeve may be sliced from a relatively long sleeve, e.g. by blades 20. The rubber may be radially injected into the mould cavity at a plurality of circumferentially placed points defined by inserted section 26.

Title: Improvements in automatic additional air valves for internal combustion engines
IPC: F02D9/00
Filed: 1920-02-07
Abstract: 156,011. Bauert, W. H. Feb. 7, 1920. Check lift valves.-In an automatic valve for supplying additional air to the induction pipe of an internal-combustion engine of the kind opened by suction against the tension of an adjustable spring, the valve seating is formed on the inner edge of the bore of a removable nipple screwed into the induction pipe, the nipple also securing to the pipe a yoke member which acts as a guide and support for the spring-tensioning means. As shown in Fig. 2, the valve 8 is secured to a tubular piston 1 provided with air inlet slots or apertures 2, and is held closed by a spring 6 bearing against a collar 4 on an adjustable rod 3. The rod 3 is adjusted, to vary the tension of the spring, either by a nut 16 or by a Bowden wire 18. The valve 8 seats against a removable nipple 9 provided with a flange 15 adapted to secure a yoke 11 which guides and supports the spring-tensioning means, The piston 1 may be surrounded by a gauze or perforated metal airfiltering screen, which may be attached to or formed integrally with a sleeve mounted on an extension of the nipple 9; alternatively, the yoke 11 may be formed as a perforated screen. Fig. 4 shows a Bowden wire control for varying the tension of the spring. The wire 18, which is attached at one end to the rod 3, is carried by a flexible wire housing 27 and is attached at the other end to a stem 24. The stem 24 slides in a socket 25 provided with a collar 26 and secured to the dashboard by a nut 31. The housing 27 is clamped at one end to the socket 25 by a nut 28 and is secured at the other end to a split socket 29 on the yoke 11. A nut 26<1> bearing against the collar 26 holds the stem 24 in an adjusted position. In the modification shown in Fig. 7, the valve 33 is hemispherical and is attached to the bridge 34 of a U-shaped wire frame 35, upon which is mounted a spring 36 the inner end of which is secured bv a hook 38 to the wire 18. In a further modification, a conical valve is used, and the frame 35 and spring 36 are inverted, the wire 18 being secured to the bridge 34 of the frame 35, and the hook 38 of the spring 36 being secured to the upper end of the valve.

Title: Improvements in and relating to heat-responsive snap-action electric switches
IPC: H01H37/48

Abstract: 599,697. Thermal switches. BERRIDGE & CO., Ltd., I. L., and COOKE, A. E. Feb. 21, 1945, No. 4329. [Class 38(v)] A thermal switch which can be detached as a unit from an electric iron, is responsive to the differential expansion of its casing and an element housed therein. A tension blade member 10 is mounted on an operating member 5 pivoted to the casing 2a at 8, and attached at 9 to a compression spring blade 6 engaging a point 7 of the operating member 5, as described in Specifications 566,762 and 567,614. The member 10 may itself carry a contact, but, as shown an insulating roller 16 in a guide 17 moves a spring blade contact 14, co-operating with a contact 13. A bar 18 having a smaller coefficient of expansion than the casing 2a, is fastened thereto at 19, and a pressure member 20 pivoted to the bar engages the operating member 5 either directly or through a ball 25. As the casing 2a expands, the member 20 rotates the member 5 whereby the blade member 10 engaging an adjustable screw 12 flexes downwards, thus causing the blade 6 to impart snap action to open the contact 14. The operating temperture is adjustable by a screw 21 which co-acts with.the pressure member 20. A knob 22 is loosely attached to the screw 21 by lugs 36 and, with the device heated to the right temperature, the screw is adjusted until the switch just opens, whereupon the knob 22 is adjusted relatively to the screw 21 so that a lug 35a bears on a stop 37. The knob and screw are then permanently secured by spot welding together discs 33, 34, respectively carried by the screw and knob. Temperature adjustment can be obtained within the limits allowed by the lug 35a and a further lug 35b. An auxiliary heating element 26 may be connected in series with the main heating element and switch, and housed in a covered recess 27.

The two end panels 22 have secured along the two upright edges metal strips 23 rounded off at both ends having a projecting portion 26 bent round through approximately 180 degrees to provide a guide flange which slidably engages in the channel 19 formed on the panels 12 and 14 by the metal strip 17 being folded round first 90 degrees, then 180 degrees, both the bends being rounded and so forming an inturned hook. The metal binding strips are also provided with mitre notches at the joins of the panel to enable the blank to be folded up more easily.

An altimeter of the type described in the parent Specification is provided with means for adjusting the position of the output member relative to a reference to introduce a correction for ground level pressure. Static pressure capsules 24, 25 rotate shaft 26 to provide one input to differential mechanism 28. Arm 39 of differential pressure capsule 22 co-operates with cam 41 on shaft 26 to move shafts 38 and 46. Shaft 46 carries a cam 42 which acts on arm 50 attached to, and forming the second input of, differential 28. The output shaft 29 of the differential operates decimal counter 19 and needle 21 to indicate altitude. The pressure capsules and differential are mounted on a support 14 movable by knob 61 through shaft 64 and differential gearing 62. Knob 61 is adjusted until counter 20 indicates the ground barometric pressure and this pressure value is converted by gearing 62 to an altitude in accordance with which the support 14 is rotated. The differential pressure capsule is connected to a Pitot tube (not shown) by flexible tubing 51 which is helically coiled around a part 56 of support 14 which mates with a cylindrical part 58 of fixed frame 11. Such an arrangement acts as a spring to absorb backlash. Specifications 438,137 and 774,341 also are referred to.
