Patent FR-2493215-A1 (FR)
Title: Mould for pressing gramophone records - having short arcuate heat transfer fluid passages for rapid and uniform temp. adjustment
IPC: B29C43/00
Filed: 1980-10-30
Abstract: Mould is of split plate construction with concentric annular channels beneath the upper plate intersected by branches from radial passages drilled in the lower plate. The radial passages are of diminishing bore to balance the drag to and across annular channels of differing radii. Alternate radial passages are used for heat transfer fluid input (22,23) and outlet (24,25) respectively. Suitable for moulding thermosetting or thermoplastic moulding matls. esp. by pack moulding with radial spreading. The relatively short and uniform fluid path length produces rapid, uniform heating or cooling and negligible differential thermal stress, so that mouldings can be made relatively thin without subsequent warping. Compared with a conventional spiral channel mould, moulding cycles for heating and chilling from 25 degrees C to 162 degrees C and back may be reduced from e.g 21s to 13.5s, using steam and water alternately. Negligible risk of vapour locks or backpressure.
Patent FR-2496787-A1 (FR)
Inventor: GOJON ROGER
IPC: F15B15/17
Filed: 1980-12-23
Abstract: A method for reducing friction between relatively sliding members (1-3, 15-17) which are subject to a relative lateral force (F). One member is given a slight rotation (R) about an axis substantially perpendicular to the direction of sliding (T) and the direction of the force (F). This may be achieved by angularly offsetting the direction of motion of one of the members with respect to the direction of sliding engagement.

One cheek (8) is lengthened on each flat polygon end by a rectangular tongue (7,7') of a width (L) sufficient that adjacent tongues can turn down along the cheek (A) walls to form a transporting case. Each cheek has two circular perforated lines with one (2) around a cheek centre.
Patent FR-2473370-A1 (FR)
Inventor: SUZUKI SYUNSUKE
IPC: B22C9/28
Filed: 1981-01-09
Abstract: A split die for the production of a rotor equipped with blades, which rotor has a bladed part with a central shaft and blades projecting radially from the latter and has a shaft or hub part not equipped with blades, is divided radially into a number of die segments which can be moved radially inwards to form a die cavity and radially outwards to open the die. Each die segment is divided in a plane perpendicular to the centre line of the die into a first part, shaped to correspond to the bladed part of the rotor, and a second part, shaped to correspond to the hub part of the rotor, these parts being held in sliding contact with one another. Immediately after the solidification of a metal melt in a region of the die cavity corresponding to the bladed part of the rotor, only the first part of each die segment is initially moved radially outwards, the purpose of this step being to reduce as far as possible the wear on this part, which is the most important part of the die, due to prolonged contact with the hot metal in the die cavity. The second part of each individual die segment is moved radially outwards only after the solidification of the metal melt in the remaining region of the die cavity corresponding to the hub part of the rotor.
