Title: Improvements in or relating to soles or combined soles and heels for footwear
IPC: A43B21/00
Filed: 1944-09-05
Abstract: 604,118. Plastic soles and heels. SALMON, A. E., and SPENCER, T. Sept. 5, 1944, No. 16925. [Class 17(ii)] A moulded sole or combined sole and heel for boots &c. consists of a felt base impregnated with a synthetic resin and having a wearing surface and, if desired, the sides or edges also with a greater degree of impregnation than the rest of the sole or consisting entirely of synthetic resin; the sole being finally moulded. In one method of forming the sole a sheet of felt is impregnated with a solution, paste, dispersion or liquid form of the synthetic resin; dried to remove the solvent, partially polymerised, and then cut to shape. Alternatively, the sheet of felt may first be cut to shape and then treated. The sole is then coated either by dipping, brushing, spreading or spraying, with the resin or is placed in a mould with one or more synthetic resins in powdered form or as a sheet or film. After the resin has been applied the sole is partially polymerised and then moulded under heat and pressure. To obtain a considerable thickness of felt impregnated as above, several sheets are impregnated, superimposed and cut to shape. If the felt is not in sheet form a matrix of the loose fibres and the synthetic resin is formed, dried in formers to the required shape and then given a further coating on the wearing surfaces of a compatible resin, by any of the methods referred to above. The sole may be finished and/or, coloured by coating with a synthetic resin or enamel, and any desired pattern may be formed on the wearing surface during the moulding operation. Specifications 582,431 and 589,652 are referred to.

Abstract: 666,342. Internal-shoe and drum brakes. GIRLING, Ltd. June 9, 1950 [June 28, 1949], No. 17053/49. Class 103 (i). In a brake with internally expanding shoes 19, each shoe has an associated finger piece 18 projecting through the web of the shoe and lightly engaging the drum when the brake is off, to maintain a predetermined clearance between the shoe and the drum. The finger is carried at the end of a yieldable lever 23 pivoted at 16 to the back-plate and engaging near its midpoint an abutment 22 on the brake shoe. Upon application of the brake the portion of the lever 23 between the abutment 22 and the finger-piece yields to permit engagement of the shoe with the drum, and upon release the lever recovers its original shape to withdraw the shoe from engagement. The finger piece carries a small pad of friction material, the wearing of this pad and the shoe lining maintaining the shoe clearance substantially constant. Instead of being integral with the end of the lever 23, the finger piece 18 may be a separate member bolted to the lever, Fig. 4 (not shown). Specification 519,787 is referred to.

Patent GB-625733-A (GB)
Title: Improvements in intermediate frequency amplifiers
IPC: H03H7/01
Filed: 1946-06-06
Abstract: 625,733. Valve superheterodyne circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 6, 1946, No. 17144. Convention date, June 6, 1945. [Class 40 (v)] In an amplifier circuit particularly for use between the mixer and first I.F. amplifier stages of an U.H.F. superheterodyne receiver an improved signal to noise ratio is obtained without the use of double tuned circuits by feeding the signals to be amplified to the cathode of a grounded grid valve via a stepdown transformer which is so tightly coupled that it behaves as a single-tuned circuit. The Figure shows the anode of a mixer valve T1 coupled by a step-down auto-transformer T to the cathode of a grounded-grid amplifier T2 which is itself coupled by a single tuned circuit to the grid of a first I.F. amplifier valve T3. Formulµ are derived from which the values of the transformer constants can be obtained for the optimum signal/noise ratio for given valve constants and a given I.F. band-width. The windings of the auto-transformer are so tightly coupled that a single-tuned circuit characteristic is obtained, the coefficient of coupling preferably exceeding <1>/3. The tuning of the input and output circuits of the groundedgrid stage is effected by using coils with adjustable iron cores and the stage is rendered inoperative, e.g. by switching off the valve heater, whilst the auto-transformer is being tuned. The by-pass condenser C shown at the tapping point of the auto-transformer is used in order to keep capacity Cp1 as small as possible. The value of the damping resistor R for a given band width and circuit constants can be calculated from a formula. As a reduction in the gain of first I.F. amplifier stage increases the I.F. noise the gain control of this stage should preferably be left in the maximum gain position.

Title: Improvements relating to internal combustion engines
IPC: F02B75/22
Filed: 1926-07-08
Abstract: 255,440. General Motors Corporation, (Assignees of Ellis, L. B.). July 20, 1925, [Convention date]. Pistons.-Products of combustion which leak past the piston into the crank chamber are discharged therefrom by a current of air, which directs the products out to the atmosphere through a port 21 in the cylinder wall. The air is circulated by the centrifugal action of the crank shaft, which sets up an air flow into the lower ends of the cylinders 10, fresh air entering the crank chamber through defecting passages 51, 52; this air is heated by passing through pipes 50 attached to the cylinders. The pipes 50 may point in the direction of the air stream set up by the engine radiator fan, and the air may be filtered by a deflector. The inlets 51, 52 may be replaced by pipes leading to the centre of the crank shaft. When the products leaking past the piston are at abnormally high pressure, air may be blown out through the inlets: this air will carry some oil with it, which will be deposited in the pipes and act as a dust filter for the subsequently entering air. In order that the products escaping past the piston rings shall not creep the whole length of the piston, a number of slots 27, Fig. 2, are cut in the lowest ring and holes 28 are made in the piston leading into its interior. The products entering the piston pass with the air current into the chambers 15 for the valve rods; oil passing with the products is used to lubricate the valve rods and is separated by baffles 53 from the gases passing to the atmosphere through the outlets 25. Oil recovered by this means returns to the crank chamber through holes 30. A groove 31 may be cut in each piston in one of the raised parts between the grooves for the piston rings, this groove registering with a small hole 32 above the main outlet 21. The hole 21 is chamfered. The piston skirt may have a number of apertures to register in turn with the hole 21, and thereby allow several discharges of gases for each reciprocation of the piston.
