Title: Pump inlet protecting cage - with perforated oscillating sides for use with heavily charged liqs.
IPC: F04B53/10
Filed: 1975-03-10
Abstract: Pump inlet protecting cage is intended for use in settlement plants dealing with liqs. which are heavily loaded with impurities. The envelope has a hydrodynamic shape with a leading edge and a symmetrical supporting structure, a rear element and a lower element close the cage on these sides while upper side is open. The lower element is free to oscillate from a point behind the pump in the direction of the circulation of the liq. The rear element can oscillate from a part of the cage above the level of the liq. The elements and the envelope are made from sheet steel or a plastic matl they are perforated with 5 mm square holes. The oscillation of the elements prevents the deposition of solid matter in the pump inlet, even if the perforations are partially blocked, the pump can still draw in a sufficient quantity of liq. Cleaning of the cage is only necessary after a long interval of three months or so, this is a most important factor for control posts of continuous, automatic purificn. stations.

Title: Lightweight coke for use in electro-reduction furnaces - produced by mixing coal with low and high caking index in specified narrow size range and ratio
IPC: C10B47/00
Filed: 1975-10-23
Abstract: A light-weight coke of high reactivity and high electric resistance for use in electroreduction furnaces is produced from hard coal of low caking power (with swelling index 4) of high volatility (>=28% volatile matter) which is graded into a narrow size range with a top screen mesh of 80 mm (20 mm) and a bottom screen mesh of >5 mm (10 mm). This coal is mixed at a specified percentage with coal of higher caking powder (over 4) and carbonised, with the coal just charged by gravity, at heating flue temp. 1100-1400 degrees C. This is a much less costly process than either the method using mixtures of high-volatile coal, low-temperature coke and pitch with stamping or by fine grinding of coking coal of medium moisture content prior to carbonising. The coke produced is of excellent quality.

Title: Volumetric rotary drum depositor for dividing baker's dough - uses adjustable cam reciprocated piston in cylinder passing diametrically through drum
IPC: A21C5/04
Filed: 1977-04-28
Abstract: The depositor comprises a dough hopper feeding down into a depositor drum rotating on a horizontal axis. A radially reciprocating piston is synchronised with drum rotation to draw in a measure of dough from the hopper outlet and to discharge the dough after drum rotation through 180 degrees. The piston now reciprocates in a cylinder bore of which the axis passes diametrically through the drum with the bore opening at two points spaced 180 degrees apart on the drum circumference. The piston length is less than that of the cylinder bore and the piston completes a full reciprocating cycle for each revolution of the drum. This means that a dough piece is deposited by each end of the piston in one cycle, i.e. two pieces per piston per revolution. A high output machine which is inexpensive to purchase and easy to maintain is provided. Dough is not unduly stressed or overheated during division, so a high quality prod. is produced.

Title: Semi-automatic brake for pivoting arm - has coil spring around axle tightened to resist rotation in one direction
Inventor: JEANGUENIN CLAUDE
IPC: B66F7/28
Filed: 1977-05-20
Abstract: The semi-automatic brkae uses a coil spring (18) to apply braking forces to a rotatable spindle (11) and is suitable for monoplanar pivotable suspension arms. The spring is wound relatively tightly round the spindle (11) and its ends (19, 20) are respectively fixed to a static member (16) and a pivotable lever (24). Rotation of the axle (11) in one direction (25) causes the spring (18) to unwind and permit rotation. Rotation in the opposite sense (26) is prevented since it causes further tightening of the spring (18) onto the axle (11). The mechanism can be used singly i.e. to control a single pivoting arm, or in combination i.e. with several arms on one or more axles. In its simpler form the mechanism may be attached to an axle (11) to which a pivot arm (10) is cottered (12), and which is free to rotated relative to two perpendicular support arms (15, 16). One end of (19) of the spring (18) may be welded to a support arm (16) and the other is fixed (22) to the lever (24).
