Title: Printing Machine
IPC: B41F31/16
Filed: 1979-07-17
Abstract: A printing machine in which a document is fed to a printing station (13) where an impression of a row of printing characters is delivered, on application of pressure between the document and the characters, to the document by a thin plastic inked tape (1) which passes from a supply spool (3) via the printing station to take-up spool (5) on which tape is incrementally wound between printing impressions. In order to reduce well of the take- up spool and axial movement of tape thereon, a rotatable cylindrical indexing member (87) provided with a circular series of projections (89) is biassed into driving engagement with tape on the take-up spool so that several layers of tape are penetrated and tape in the outer layer perforated by a projection extends through apertures in inner layers formed by the projection thereby fixedly securing the outer layer relative to the inner layers. <IMAGE>

Title: Vehicle Brake Control Valve Assemblies
IPC: B60T8/18
Filed: 1979-08-14
Abstract: A two stage control valve for a vehicle braking system comprises a housing (1) having a control pressure input port (2), an output port (3) for connection to a vehicle brake actuator, and an exhaust port (4). A stepped piston (5) works in a bore (6) in the housing. An input chamber (8) is connected through the intermediary of a limiting valve (9) to the input port (2) and the pressure in that chamber (8) acts on the smaller piston portion and an outlet chamber (7) is connected to the outlet port and the pressure in the outlet chamber (7) acts on the larger piston portion. An intermediate chamber (10) is connected permanently to the input port (2) and the input, pressure acts on the stepped portion of the piston. A triple valve (19) is operable to close off the exhaust port (4) and connect the outlet chamber (7) to a pressure source upon movement of the piston (5) in response to input pressure. The pressure source may be the control pressure at inlet 2 (Fig. 2) or from an inlet 21 connected to a separate air supply. The arrangement is such that when a predetermined input pressure is attained the limiting valve (9) closes and further increase in input pressure acts only in the intermediate chamber so that a proportion of the input pressure together with the air pressure trapped in chamber (8) is transmitted to the outlet, the outlet pressure thereby increasing at a reduced rate. <IMAGE>
