Title: Rotation and axial displacement transducer - has single sensor and tapered cylindrical member attached to component being measured
Inventor: TUMBER BRIAN WILLIAM
IPC: G01P3/483
Filed: 1980-10-31
Abstract: A signal representative of the speed of rotation and axial setting of an axially movable rotating component (10) is provided by a member (11) associated with the component and a sensor (14) e.g. a capacitive, inductive, magneto-resistive or Hall effect device. The surface of member (11) is generally conical so that its distance from the sensor varies with the axial position of the rotating component. In addition the member (11) has a projection (12) and a slot (13) whose distances from the sensor remain constant so that the resulting frequency of the sensor output depends on the speed of rotation of the component. In a further embodiment a disc with projections of differing heights is mounted on the component. The component may comprise the rotor of a fuel injection pump for an IC motor.

Title: Telemanipulator for use with radioactive or corrosive media - removably mounted in protective casing and sleeve
Inventor: GERMOND JEAN-CLAUDE
IPC: B25J9/04
Filed: 1980-11-17
Abstract: The telemanipulator comprises one or more articulated arms operated by a control motor unit and positioned in a confinement chamber. The control unit is mounted in a rigid protective casing and the arm is positioned in a protective sleeve. The casing has a removable panel on the face opposite that on which the arm is mounted so that the arm and the control unit can be removed from the confinement chamber after removing the panel. The telemanipulator is used for handling materials which are corrosive or radio-active or are in corrosive or radioactive environments. The design facilitates replacement of the arm since the contaminated protective casing and sleeve remain in the confinement chamber when the telemanipulator is removed.

Title: Photosensitive linear charge transfer colour image analyser - has photoelement strips, read device and memory integrated on one substrate
Inventor: DESCURE PIERRE
IPC: H01L27/148
Filed: 1980-11-21
Abstract: The colour image analyser uses a circuit which is integrated onto a single semiconductor substrate and comprises two strips of N photosensitive elements spaced apart by a distance equal to one or more times the corresponding element dimension. At least N elements are sensitive to green, the remainder to blue and red, and distributed to receive all of the radiation of each image line to be analysed. The element charges are transferred simultaneously to a read device of two parallel input series output shift registers. Two charge read stages are connected to each register output. A memory has N shift registers of series input/output which are located between the strip receiving the first image line and one read device register. The resulting charges are stored in the memory and then transferred to the next register while the other strip charges are transferred to the other read device register.

Title: Hydraulic service accumulator system - with a prime motor brake maintains lower idling energy losses than sole use of recycling system
Inventor: CHALIGNE GERARD
IPC: F15B1/033
Filed: 1981-02-17
Abstract: A hydraulic pressure system acting via an accumulator to serve several hydraulic presses or injection machines and having a pump driven by an electric motor is provided with a brake to allow the motor to operate under reduced load when not charging the accumulator. Esp. for relatively large systems with e.g. a 30 kW motor to serve several dozen hydraulic machines where the energy used to develop pressure is significant compared with that used for other purposes, e.g. direct heating of extrusion barrels and where the frequency and brevity of the pressurisation cycles precludes the stopping and starting of the motor due to wear and tear and inefficiency. Use of a brake coupled with isolation from the pressurisation or recycle circuits may allow the motor to run at reduced energy levels without stopping, e.g. 1.6 kW instead of 6.1 kW for recycle purposes, saving 4.5 kW for up to 55% of the overall operating time, i.e. 10 MWh per year.

Abstract: Before the thermoforming of a plastic sheet, a paper container corresponding to the outer shape of the container to be produced is inserted into the thermoforming mould. The paper container ensures the dimensional stiffness of the container and the plastic material ensures its leak-tightness. The container produced according to the process has a considerably reduced proportion of plastic material and the outer paper layer (16) of the container facilitates its decoration.
