Title: Improvements in apparatus for propelling projectiles
IPC: F41B6/00
Filed: 1919-03-24
Abstract: 144,409. Villeplee, A. L. O. Fauchon-. March 24, 1919. Ordnance, electro-magnetic. - Consists in improvements in the electro-magnetic gun described in Specification 128,241, whereby a magnetic field is set up across the bore of the gun, and an electric current is passed across the projectile, which is of circular cross-section, at right angles to the magnetic field. Fig. 1 is a transverse vertical section of the gun with a projectile f between the longitudinal guiderails b and c. Fig. 3 is a sectional plan on the line z-z<1>, Fig. 1. The gun comprises a magnetic frame a a', the sections of which are bolted together longitudinally and transversely, as shown. The frame is formed with pole-pieces at shown in Fig. 1, which extend the length of the gun, but do not quite touch the projectile. The field-winding comprises insulated conducting bars d, e extending the length of the upper pole, and similar bars d<1>, e<1> along the lower pole. The bars d, e and d<1>, e<1> are transversely connected at their front ends by cross-pieces k, and the rear ends of the bars d, d<1> are connected by crosspieces j to the rear end of the guide-rail c. To discharge the gun, a heavy current from a flywheel dynamo is switched on and traverses the following circuit, indicated by the heavy broken lines in Fig. 1, guide-rail b, projectile f to guiderail c, rear cross-connexions j, bars d, d', front cross-connexions k, bars e, e', and passes back to the motor-generators from the rear ends of the bars e, e<1>. Instead of a dynamo, storage batteries may be employed, which are re-charged after each shot. The magnetic frame may be omitted, the field created by the windings being alone relied upon. Alternatively, the winding- bars d, d<1>, e, e<1> may be omitted, the guide-rails b, c, in themselves constituting the winding. The projectiles and guide-rails b, c may be rifled, and the bearing surfaces of the guide-rails be made detachable from the body of the rail for ready renewal. The projectiles are coated with an easily fusible alloy which is melted by the current during the passage of the projectile along the gun.

Title: Fluid pressure operated braking systems for vehicles
Inventor: MORTIMER FRANK RADCLIFFE
IPC: B60T8/74
Filed: 1963-02-23
Abstract: 1,066,441. Fluid pressure braking systems. DUNLOP RUBBER CO. Ltd. Feb. 7, 1964 [Feb. 23, 1963], No. 7375/63. Heading F2F. A fluid-pressure operated braking system including an anti-skid device has valve means for interrupting the substantially unrestricted flow of fluid from the supply to the brakeapplying mechanism immediately on operation of the anti-skid device and thereafter permit a restricted flow of fluid to the brake-applying mechanism so that re-application of the brake by the restricted flow of fluid commences immediately upon cessation of the release of fluid from the applying mechanism by the antiskid device. Fluid pressure supplied to the port 4 passes the spring raised valve 16 and traverses passages 29, 30, 8, 68 to pass unrestricted to the brake-operating means (not shown). On the actuation of an anti-skid device of the over-running flywheel type to release fluid from the applying mechanism, the released fluid, entering at 11, lowers the piston 33 and the valve 16. Fluid entering at 4 is thus diverted through passages 25, 26, 64 to helical passages 80, 84 on the surface of a piston 67 before passing out of port 69. The position of the piston, and thus the length of the restrictive passages 80, 84 is regulated by the brake applying pressure in the bore of port 69, the pressure moving the piston against a spring 78. The restriction is thus greater at low application pressures, corresponding to landings on icy runways and the re-application of the brakes when the anti-skid device ceases to operate is more gradual than when a dry runway is landed upon and the application pressure is higher. A bore 40 allows any pressure which has built up in space 43, while valve 16 was raised, to leak off to the reservoir through a restricted orifice. In a modification two restrictor devices may be used when two brakes are to be operated from a single pressure line.

Abstract: 912,495. Tilted pad-bearings. SCHAEFER, E. J. March 1, 1961 [March 2, 1960], No. 7445/61. Class 12 (1). A thrust bearing of the tilting pad-type comprises a bearing ring 34, which may be of graphite, located by pins 36 to rotor 13 and co-operates with a number of segments 37 which are mounted on annular supporting ring 38, which in turn is carried by supporting ring 54. The segments are spaced circumferentially on ring 38 and each is positioned by a spherical pivot 39 on ring 38, locating in corresponding depressions 41 in each of the segments, thus promoting universal tilting means. To locate the segments on their pivots 39, clips 42 are fixed to ring 38 between the segments, without inhibiting their tilting action. The adjacently mounted supporting rings 38 and 54, and the end bell 19 are positioned by diametrically situated spherical pivots 52 and 56 locating in depressions 53 and 57 respectively, thus whilst permitting tilting to provide equal load bearing on the segments, relative rotation of the supporting rings between themselves or the bell end is prevented.

Abstract: 526,134. Optical sound-recording apparatus. KOLB, O. K., and PRATT, A. S. March 9, 1939, No. 7577. [Class 40 (ii)] [Also in Group XL], Apparatus for producing " noiseless " photographic sound-records either of the asymmetric (push-pull) or of the normal variablewidth type, comprises a single oscillograph 5, two masks 3, 4 each bearing one or more triangular apertures, and means for moving the masks in opposite directions in a manner depending on the intensity of the sound being recorded. In the apparatus shown, the masks 3, 4 are mounted on rods 9, 10 which are linked by a lever 11 and supported by parallel-motion springs 12, 13, 14. The rod 9 is connected to a coil 15 which is located in the annular field of a magnet 16, and through which a biassing current, varying with the intensity of the sound, is passed. Alternatively, instead of linking the rods 9, 10 together, each one may be actuated by a separate driving-unit 15, these units acting in opposition. Images of the apertures 3b, 4a in the masks are projected by the mirror of the oscillograph 5 on to a slitin a mask 6, the oscillograph mirror being vibrated in accordance with the sound-waves. A noiseless pushpull record is produced by this arrangement. The two oppositely movable masks, together with their driving-unit or units, may be mounted in a removable fixture which can be replaced by one bearing a single movable mask having one or more triangular apertures for producing normal single-track or multipletrack records. Preferably, however, the support for the mask and magnet system is slidably mounted so that it can be moved to enable the mask 3 alone to be brought into the recording light beam. With this adjustment, the images of the apertures 3a, 3b produce a normal twin-track noiseless record. As an alternative, the aperture 4a alone could be brought into use, to form a normal single-track record.
