Title: Concrete casting mould filling appts. - wet concrete discharged onto slinger wheel with scraper blade
IPC: B28B1/34
Filed: 1975-05-12
Abstract: A concrete slab casting plant includes a feed system for wet concrete, between a supply hopper and a casting mould underneath, so that the concrete is discharged at a speed of between 30 and 80 m/sec, and in equally sized pieces of between 100 and 1000 and 1000 cubic centimetres. The wet concrete is deposited first onto a belt conveyor which discharged it onto the periphery of a wheel (2) with a scraper blade (3) rotating inside a circular housing, discharging the concrete through a bottom opening, into the mould (12) below. This is suitable for fine material. For various grades of coarseness, a further design has a flanged wheel onto the side of which concrete is discharged, and which carries a scraper blade extending from its side, so that the concrete enters its hollow interior for discharge from the bottom.

Title: Swimming flipper with central foot recess - is partially slit through each side to form hinges for outer portions
IPC: A63B31/14
Filed: 1975-06-17
Abstract: The flipper (10) for attaching to a swimmer's foot is made from rubber of plastics and is paddle shaped. The inner portion (12) is enlarged to form a housing (14) for the foot, held by an adjustable strap (16, 18) behind the heel. Along a line (28, 30), each side of this housing, the flipper is partly slit through from the top. The thickness left underneath forms a hinge and permits the outer flat portions (24, 26) to flex downwards. When exerting a rearwards push, the hinges close and the whole of the flipper area is used for propelling. On returning the foot forwards, the hinges open and the other portions flex inwards to reduce water resistance.

Title: Stroke adjustment for double column press - has adjustably mounted eccentric cross shafts geared to flywheel shaft
IPC: B30B1/26
Filed: 1975-09-24
Abstract: The press drive works on a flywheel mounted on a shaft. The shaft is connected by a pinion to one of the gears mounted on the cross shafts. The cross shafts are in the form of eccentric shafts. Connecting rods transmit the movement of the eccentric to the press. The eccentric bushes can be connected to claw bushes mounted on the eccentric shaft via claw couplings. Synchronisation wheels are coupled to gear wheels mounted on the eccentric shafts. Adjustment of the press stroke is by axial movement of the claw bushes via press discs screwed to the claw bushes. This uncouples the claw bushes from the eccentric bushes. The eccentric bushes can now be rotated.

Patent FR-2303409-A1 (FR)
IPC: H02P27/02
Filed: 1976-02-09
Abstract: A control voltage, which is dependent on an actual value and a required value, is supplied through a regulator (21) to the controllable rectifiers which are located in the winding circuits of the three-phase motor. The actual value is supplied by an actual-value sensor (20) which is coupled to the drive shaft of the motor, and the required value is supplied by a required-value transmitter (26). The required-value transmitter produces the required value by integrating an adjustable input signal, additionally differentiating the input signal, by means of a rounding device (25), for smooth acceleration and braking of the rotation speed, and the differentiated input signal being included in the integration process with opposite polarity to the original input signal. Once the differentiation process has been completed, the required value rises or falls with an adjustable gradient until a maximum or minimum value is reached. This method is particularly suitable for controlling the drive motor of a passenger lift.
