Title: Assembly drum for tyres, bandaged and laminated structures - with closely controlled axially-moving details and resistant assembly surface
Inventor: CSATLOS GEZA
IPC: B29C67/00
Filed: 1974-08-28
Abstract: An assembly drum for tyres, and bandaged and laminated structures generally, has control gear, assembly surfaces formed by a radially expandable centre section and axially displaceable end pieces on the axially bored drum shaft, the end details sliding to and from the centre section separately under the control of the pressure circuit. A double pressure chamber opens outwards in each end detail and a fixed piston is secured on a guide sleeve with a guide rod projecting through an assembly flange on the drum shaft, the guide rods being bored to form a connection with a pressure source which moves the end detail relatively to the fixed piston. The drum shaft has two opposing elongated slots each of which reach the end detail, and within the bore of the drum shaft there are two rack details one of which lines up with the slot and carries a guide block projecting through the slot and bolted to the end detail. A sprocket engages with the racks so that when pressure is applied to the pressure chamber these details regulate the motion of the end details. Centrally the drum has a radially expandable zig-zag form device comprising alternate fixed and movable segments within a cylindrical sleeve, each fixed segment being supported by one of a series of links moved by levers and joined to a movable segment by another link. The zig-zag form of the segments backing-up of the assembly surface prevents the radial wires in the carcase from extruding rubber between the segments and glueing up due to penetration of the rubber through collapsed segments of the carcase.

Title: Crosstalk and noise suppressor for stereophonic receivers - continuously alters relative crosstalk attenuation to optimize signal to noise ratio
Inventor: MEYRAT PIERRE DR
IPC: H04B1/16
Filed: 1974-12-23
Abstract: The channel crosstalk and noise suppression circuit, for stereophonic receivers, continuously alters the gain or attenuation in one channel so that the distance between crosstalk noise-level and channel signal-level varies in a way which keeps the signal to noise ratio as high as possible. Normally the overall noise level increases when noncontinuous or fixed attempts are made to reduce crosstalk. The control signal for the variable attenuator or amplifier (7) in the L-R channel is obtained from the L+R channel signal by a diode detector (4) or from the receiver HF input voltage. The relative crosstalk noise level is more heavily suppressed for the higher than for the lower frequencies.
