Title: Improvements relating to the manufacture by rolling of annular articles
IPC: B21H1/12
Filed: 1944-03-24
Abstract: 583,187. Rolling annular bodies. BRASSERT & CO., Ltd., H. A., UDALL, W., and BOTTAMS, S. March 24, 1944, No. 5522. [Classes 83 (ii) and 83 (iv)] Making toothed gearing.-Annular articles such as wheels and the races of ball &c. bearings are produced by rolling blanks, having the grain extending parallel to the axis between internal and external rolls so shaped as to provide a closed pass at the end of the operation. In the production of hubs and rims for gearwheels, a blank cut transversely from the end of a circular section bar has a central hole punched and is then divided into two annular blanks, the inner being employed to produce the hub. This blank 24, Fig. 7, is mounted on the reduced end 28 of a roll 29 which is then advanced into the outer roll 35 and into spigot and socket engagement at 31 with a complementary roll part 30. The rolls are driven at related speeds and by relative lateral movement the blank is rolled out, the rolls forming a closed pass at the end of the operation. When the reduction of section commences, the drive to one roll is disconnected. A mill for carrying out the above operations is described in Specification 583,195. The roll 35 is in two sections 36, 37 to permit removal of the finished rings. Rings partly formed may be finished rolled or rings of finished shape may be rolled in the closed pass to alter the grain structure or produce surface hardening. In this case, the preliminary heating is carried out in an inert atmosphere. In rolling the outer blank, similar rolls are employed except that the neck 28 is grooved to form a rib instead of the roll 35. The wheel is completed by welding an annular web to the end ribs and is finished by cutting teeth and a keyway and by grinding. In a modification, when rolling the outer section, rolling is completed before the blank attains the diameter of the outer roll which is not then divided to permit removal ; centrifugal force being relied upon to maintain the circular shape.

Title: Improved gas generator and method for generating combustion gas under pressure
Inventor: BAUER STEFAN GEORGE
Filed: 1958-02-22
Abstract: 858,601. Generating combustion products under pressure. ROLLS-ROYCE Ltd. Dec. 12, 1958 [Feb. 22, 1958], No. 5817/58. Class 51 (1). [Also in Group XXIX] A gas generator (Fig. 1) comprises a combustion chamber 10 having means 11 for inserting in the chamber a charge of air at supersonic velocity, opposite walls 17, 18 adapted to reflect the charge, inlet means 13, 14 for injecting a charge of combustible mixture into the chamber, and outlet means 15 for allowing a controlled outflow of the products of combustion. Compression ignition of the combustible mixture takes place when the reflected shock wave travelling from right to left impinges upon a portion of the shock wave still travelling from left to right. The detonation wave will then continue to travel to the left and will be reflected at the end 18 thus repeating the process without the necessity of inserting a further charge of air. Connected to the outlet 15 is a tuned filter 16 arranged to reject frequencies in the order of the oscillatory frequency of the shock wave. The mixture inlet valve 14 (Fig. 2) comprises a piston 19 movable in a chamber 20 and attached to a diaphragm 24 forming one wall of a chamber 25 and arranged to oscillate at a frequency equal to that of the shock wave. This frequency is thus imparted by the diaphragm to the piston which uncovers the mixture inlet port 21 allowing the combustible mixture to be injected once during each oscillation of the shock wave. In another embodiment, Fig. 3, combustible mixture is injected through two inlets 32 and 33 into a combustion chamber 27 the inlets being controlled by a rotatable disc 36 having three apertures 38. The disc is rotated by an electric motor 45 set at the oscillatory frequency of the shock wave or may be revolved by turbine blades situated across each of the apertures 38. In operation the charge of air at superonic velocity is injected into the chamber 27 by a device 28 and oscillates at supersonic velocity in the chamber, the difference being that there are now two ignitions per oscillation.

Title: Improvements in and relating to electro-pneumatic converter devices
IPC: F15B5/00
Filed: 1964-02-12
Abstract: 999, 686. Controlling fluid flow; fluid-pressure servomotor systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 12, 1964 [Feb.15, 1963], No. 5911/64. Headings G3H and G3P. A frequency sensitive transducer for varying a pneumatic signal in response to an electrical A.C. input consists of a torsional resonator of which a torsion rod 2, Fig. 1, is clamped at 3 and carries a transversely magnetized cylindrical armature 1 arranged so that the poles normally lie as shown in Fig. 18 in relation to fixed pole pieces 8 energized by a winding 9. The upper end of the armature is carried in a bearing in a tubular member 6, and escape of air from lateral openings in this member is normally prevented by a member carried by the armature, but when the latter is angularly de - flected or oscillated, escape of air is permitted. The pressure of air between the escape passage and a restriction in the supply may be applied to a piston (not shown) which may provide a feedback in the form of an electrical signal or an adjustment of the supply restriction. The armature 1 may be brought into oscillation when either a frequency modulated signal applied to the winding 9 coincides with the natural frequency of the armature and torsion rod, or the voltage of a constant frequency signal coinciding with that natural frequency is increased above a certain value. The natural frequency of the armature and torsion rod may be varied by adjustable screws (not shown) projecting laterally from the lower part of the armature, and adjustable damping vanes may also be carried by the armature. Several forms of valve for controlling the escape of air are described. One comprises a rod 14, Fig. 4, in guides 21 which may be oil sealed, and recessed at 15 to control escape from a port 16 communicating with a chamber 20 which is connected with the controlled piston and fed through an adjustable restriction 18 from a supply conduit 17. Other forms of valve are rotar cylindrical elements with multiple porting. Fig. 9 illustrates another form consisting of a spring arm 51 normally pressing against a valve seat 52 but lifting thereform as the armature 14 is oscillated. A single unit may contain a number of armature assemblies tuned to different frequencies and arranged to be controlled from a single input winding. In a modification, the torsional oscillations of the armature are employed to deflect the upper end of the armature laterally so that it will also oscillate, at a lower natural frequency, by bending of the torsion rod. In this way the apparatus can respond to a lower frequency envelope imposed on the higher frequency to which the armature responds torsionally. Fig. 16 shows the upper end of an armature 58 and torsion rod 60 modified for this purpose. A flat-bottomed notch 63 engages a fixed tongue (not shown) so that as the armature moves angularly it is also deflected laterally, and this deflection is transmitted by an abutment 65 to pneumatic control means.
