Title: Vehicle friction clutch plate - has coil spring transmission with secondary friction pads to dampen rotary vibrations
Inventor: STICHLER BERND
IPC: F16F15/129
Filed: 1976-03-11
Abstract: The vehicle transmission clutch has a splined hub which is provided with a radial flange plate (15). Ring plates are located on either side of the hub flange. A circular set of friction elements is attached to one of the ring plates. Spacer bolts join the two ring plates through slots in the hub flange. A set of secondary friction pads (17) are located between the ring plates and the hub flange (15). They are under compressive loading due to a number of radial leaf springs. The ring plates and the hub flange are coupled by a number of circumferentially located coil spring. The relative rotary movement between hub and ring plates is thus braked by the friction pads (17) in order to dampen rotary vibrations.

Title: Forklift truck load limiting equipment - has bypass between pump and nonreturn valve controlled by sensors
Inventor: ANDERSSON AKE
IPC: B66F17/00
Filed: 1976-06-30
Abstract: The equipment automatically limits the weight of the load, being particularly for high-lift forklift trucks. The pressure in the lifting rams is used, if necessary in conjunction with lift height sensors, to operate sensors stopping the lifting movement. A non-return valve is mounted in the pipe between the pump and the control valve regulating the lift height so that fluid can only flow away from the pump. A unit (5) is connected to this pipe (8) between pump (2) and non-return valve (4), opening a further pipe (6) leading back to the fluid reservoir (7) under the influence of the sensors, thus stopping the flow to the rams (1).

Title: Printed circuit board - produced by currentless deposition of thin film resistors and conductor tracks from electrolytic plating solns.
Inventor: MORISHITA HIROSADA
IPC: H05K3/38
Filed: 1977-01-11
Abstract: Printed circuit boards with thin-film resistors and conductor tracks are produced by coating a board with an adhesive or light-sensitive layer. Through holes are provided where desired. A thin-film resistor layer of 0.1-1 mu thickness is deposited from a plating soln, requiring no electric current. Copper tracks are then deposited from a plating soln. without electric current only at the parts where conductor tracks are required. This results in thin-film resistors with min. fluctuations in resistance values. The latter are also less affected by thermal action. These printed circuits are therefore functionally more reliable.

Title: Clamping hinge for frame-saw blade - has resilient shaft of hinge remaining curved when stretched to compensate blade length variations
Inventor: ZAHLES HANSROLF
IPC: B27B3/30
Filed: 1978-01-18
Abstract: The pivoting hinge is for frame saw blades supportable against the lower frame saw beam, with an abutment sited on the lower hinge piece. The shaft (2) of this lower hinge piece (1) is resilient and is curved, in common with the abutment (3).

Title: Self-regulating exchanger element for exchanger column - has vapour inlet opened proportionately to fluid height on bottom
Inventor: WIESSNER FRANK DIPL ING
IPC: B01D3/16
Filed: 1978-10-26
Abstract: A sleeve projects downwards from a bottom partition in a column for the exchange of matter between fluid and gaseous media which are directly contacted with each other. In its upper zone the sleeve has a number of slots which are pref. parallel to the axis of the sleeve and form passages. Inside the sleeve which is movable up and down, is pressed upwards by a spring. The hood has side cheeks reaching downwards which close the section of the sleeve, and is restricted in its up and down motion by stops. In the top position the side cheeks close the slots whilst in the bottom position of the hood the slots are fully open. Used to remedy the failings of conventional exchanger elements esp. in rectifying columns which act differently according to the level of the fluid on the bottom, so that the operation is inefficient. The control of the exchanger is not now effected by interplay between vapour flow and fluid height, but by their spen. The column of fluid represents one quantity whilst the vapour flow represents a variable quantity.

Title: Pressure, operating path, temp. and time control in chipboard mfr. - by simultaneous recording of deviations from ideal parameters on fast-moving graph paper
Inventor: IMLE HARTMUT ING GRAD
IPC: B30B15/26
Filed: 1978-11-25
Abstract: Device for recording pressure, working path, temp., and time in single- or multi-platen presses used in mfr. of chipboards, is adapted to record those four parameters simultaneously upon graph paper which advances at an even rate. The paper moves at relatively high speed (about 2400 mm/h) thus ensuring that even very small changes in any one of the parameters are clearly discernible. An ideal pressure, operating path, temp., and time diagram is indicated e.g. printed, on transparent paper and this is compared with the actually recorded diagram so that hydraulic pressure control and regulating of heating system of the press can be simply and rapidly adjusted as required.
