Title: Disc brakes with hydraulic operation - have sets of fixed and moving discs round shaft with hydraulic release system
Inventor: SEYBOLD JOHN MARK
IPC: F16D65/18
Filed: 1976-10-13
Abstract: The disc brake is for earth moving machinery and also for finishing operation machines with hydraulic systems. The provision of a secondary parking brake system does not require a high hydraulic fluid pressure. There is a bearing support (21) for the shaft (17) fixed to the housing and a series of fixed and rotating discs (29,30). Splines (19) hold the detachable rotatable discs (30) to the shaft. The brake is actuated by a tube shaped piston (36) concentric to the shaft which presses against the discs and is supported against the housing by a spring (39). A chamber (46) formed behind a flange on the piston is connected to the hydraulic system and application of pressure into this chamber causes the brake to be released.

Title: Sound insulated roller hung partition wall - protects against fire with elastic top sealing elements spring:loaded to move against rail
Inventor: EKEBERG JOHAN
IPC: E06B5/16
Filed: 1976-11-20
Abstract: The wall panels (5) for the partitioning wall are suspended on rollers (2) attached to the ceiling, below a rail (1).

Title: Double acting press for moulding concrete blocks - where mould is vibrated to produce high density in blocks
Inventor: KITAHARA YUTAKA
IPC: B28B3/02
Filed: 1977-03-23
Abstract: Press for moulding concrete blocks uses a lower traverse joined by guide bars to an upper traverse fitted with pivot mountings from which work cylinders (I) (a) are suspended; side plates are also fitted between the two traverses. In (I) (a) are piston rods carrying holders (b) connected via springs to a press table frame (c). In the sides of table (c) are (I) (d) with piston rods using spring mountings to draw a moving traverse fitted with a ram downwards. The ram compacts the concrete mixt. in a moulding frame (e) located above a plate (f) mounted on table (c); after compaction, table (c) is lowered, so plate (f) carrying the moulded block can be removed via transverse conveyor rails. Several sets of limit stops control the strokes of the various moving parts of the press; and the side plates have swivel mountings for two pairs of plates carrying four motors, two on each side of the press; the motors vibrate moulding frame (e). Homogeneous concrete blocks can be made with high density using pronounced vibration without the latter being transferred to the press frame.

Title: Extensive monocrystalline film prodn. at high growth rate - by passing temp. profile along polycrystalline or molten strip to give convex growth junction
Inventor: SCHOPPER ERWIN PROF DR
IPC: C30B15/00
Filed: 1978-04-20
Abstract: Prodn. of monocrystalline films of large surface area at high growth rate is achieved by passing a temp. profile along a polycrystalline or molten strip of the starting material, so that the transition into the monocrystalline zone takes place with a growth surface, the intersections of which, parallel to the plane of the film, have convex curature.
