Title: Improvements in vacuum operated brakes
IPC: B60T13/24
Filed: 1932-12-09
Abstract: 410,540. Vacuum brakes. AUBIN, E., Elmstead, West Wittering, near Chichester, Sussex, and CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury, London.- (Representatives of ROYCE, SIR F. H.) Dec. 9, 1932, No. 34972. [Class 103 (i).] A vacuum brake system comprises pistons slidable one within the other and connected respectively to the pedal and to the brakes and having co-operating ports to give a " follow-up action, the arrangement being such that on operation of the pedal the one piston first moves the other directly and then the vacuum connection is opened to assist the operation, the vacuum reacting through the one piston on the pedal to indicate the vacuum effect on the brake piston. The piston b connected by rod c<1> to the brakes and, sliding in a fixed cylinder a has a sleeve extension b<1> slidable in an extension b<2> of the cylinder. The piston e slidable within piston b and connected by rod e<1> to the pedal has a sleeve extension e<3> slidable in the sleeve bl. The sleeve e<3> has ports g<5>, connected by a recess g<8> in the sleeve and the sleeve b<1> has ports g<4>, g<6>. The vacuum source is connected by pipe g to the recess g<3>. A groove h2 in the sleeve e<3> is open at one end to the atmosphere. A shoulder f on the piston e normally engages a shoulder on the sleeve b<1> so that when the piston e is moved to the left to apply the brakes the piston b is at first positively moved and when the port g<4> registers with the recess g<3>, the vacuum source is connected to the cylinder a through the recess g<8> port, g<6> and passage g<11> so that the movement of the piston b is assisted by the vacuum. This movement corresponds to the movement of piston e since slight continued movement of the piston b relatively to the piston e first blanks the port g<5> to cut off the vacuum and further movement connects the port h<1> to the groove h<2> to connect the cylinder a to atmosphere. The vacuum in the cylinder a acts through the port h upon the piston e and thus a reaction is exerted on the pedal which indicates to the driver the pressure applied to the brakes. When the pedal is released, the piston e moves to the right connecting the cylinder a to atmosphere through the port h<1> and groove h<2> thus releasing the brakes.

Title: Improvements in wrappers for bread
IPC: B65D65/38
Filed: 1922-12-27
Abstract: 201,844. Emmerson, F. W. Dec. 27, 1922. No Patent granted (Sealing fee not paid). Materials, special.-A material for wrapping-up bread consists of waxed paper perforated with any number of small holes in any position. The paper is perforated before the proofing process, and the holes become filled with the proofing material during coating. When the wrapper is placed around a hot loaf, the proofing material in the perforations becomes soft and allows the steam from the loaf to escape. When the loaf cools, the material solidifies in the perforations thus making the wrapper waterproof.

Abstract: 1,098,424. Railway vehicle suspension. BRITISH RAILWAYS BOARD. Aug. 10, 1966 [Aug. 17, 1965], No. 35209/65. Heading B7L. [Also in Division P2] A railway vehicle suspension means comprises a substantially cylindrical liquidfilled rubber bag 1, Fig. 1, extending longitudinally of the vehicle and having an oval cross-section transversely of the vehicle, the bag being sandwiched between an upper plate-like member 2 secured to or forming part of the vehicle frame 4 and a lower plate-like member 3 secured to or forming part of the top of an axle box 5, the bag-engaging surfaces of the members 2 and 3 being curved concavely towards the bag. Upper and lower longitudinal ribs 6 moulded to the bag 1 engage in longitudinal grooves 7 in the members 2 and 3 to positively locate the bag between the members. Alternatively, the bag may be bonded to the concave surfaces of the members 2 and 3. The transverse curvature of each member 2 and 3 is circular, but if a non-linear characteristic is required, the curvature is non-circular. The suspension permits transverse displacement between the frame 4 and the axle box 5 and controlled small movements in yaw but is stiff in the longitudinal direction. The bag performs a rolling movement during transverse displacement.
