Patent FR-2476363-A1 (FR)
Title: Electronic tape tension controller for reel to reel recorder - optically measures spool speed and uses variable amplitude fixed frequency generator to drive tape motor
IPC: G11B15/54
Filed: 1980-02-14
Abstract: The motors have their terminal voltage regulated in proportion to their speed to provide controlled driving torques on the take up and feed spools to reduce tension in the tape. An opto coupler (21) senses the passing of slots (20) cut in an edge under the reel drive table (19). A fixed amplitude square wave is thus generated at the opto coupler with a frequency proportional to the angular velocity of the drive. A frequency to voltage converter (22) gives a DC output voltage (24) proportional to input frequency. An inverter circuit (25) generates a fixed frequency alternating voltage which is proportional in amplitude to the voltage (24) from the frequency to voltage converter (22). The variable amplitude alternating voltage is applied to the drive motor (28) of the reel drive table and the motor runs at a speed proportional to the amplitude of the applied voltage.

Title: Synchronising image transfer cylinders - uses sensors detecting peripheral markings to produce signals controlling rotational speeds
Inventor: BRUIJN CEES DE
IPC: B41F13/14
Filed: 1980-02-29
Abstract: The image transfer system comprises a number of transfer cylinders (1-3) which are to be driven synchronously. Each cylinder carries markings (10-12) around its periphery which are detected by a sensor (13-15) which produces signals in response to the passing markings. The signals represent the angular position of that cylinder relative to a reference and are fed into a control circuit (16) which adjusts (7-9) the drive (4-6) of one or more cylinders so as to correct any deviation from their desired relative angular posn. The markings may have binary characteristics and may be arranged in axially adjacent peripheral series, each acting on its own detector, so that, at any moment, a number of simultaneous signals is produced by each sensor which together represent a multi-bit code.

These flexible shafts (12) are guided in the distributor housing (6) and are coupled to the corresponding drives. They normally rotate at different speeds, driven by the same motor (5). The machine stand (3) includes a control panel (14) as a component. A coolant pump (16), a coolant reservoir (17) located underneath it, a drive controller (19) and a programme controller (20) are also provided as a further standard group. A maintenance unit (22) is installed as well as the above items. All these assemblies are standardised. Said assemblies can be assembled in a modular manner in accordance with the desired operating range of the machine tool, without one or more groups having to be manufactured, as desired, as individual structures. This results in improved economy in special machine construction.

Title: Display screen with thin silicon substrate - has anti-reflection coating and bonds thinned layer to mon:oxide layer with epoxy resist and bonds to glass with coating
Inventor: EDWARDS THOMAS WILLIAM
IPC: H01L21/308
Filed: 1980-07-24
Abstract: The display has a thin substrate, which has an anti-reflection coating. The layer formed on the substrate is masked to prevent attack from the contents of a dilution bath, which will only attack the exposed sections. The thinned plate (44) is made from silicon and has a refractive index of approx.3.6. Under that there is a layer (46) of silicon monoxide with a thickness equal to approx. one quarter of a wavelength. The refractive index is between that of the bonding agent such as epoxy and silicon. This layer is followed by a layer of glass (48) with a refractive index of approx. 1.5. The glass has a coating that reduces the refractive index.

Title: Remote control appts. using pulses on supply wires - has rotating switch moving forward one step in response to each received pulse
IPC: H02J13/00
Filed: 1980-10-10
Abstract: The system uses pulses transmitted via the normal electricity supply lines. A rotating switch (1) includes a flat contact disc with six contact pads (2a,2f) arranged around its circumference. A rotating arm (4) is mounted centrally to contact each of these pads, in turn. The arm is rotated by steps by an electromagnet (8) operating on a pawl (5) which engages a toothed wheel. The arm may be advanced by one step by each pulse it receives, or its rotation may be controlled by the duration of pulses, or the interval between them. Control of a particular function is carried out by relays (10a,-10c) which are energised when the rotating arm contacts an appropriate pad. A circuit resetting the counter to zero (13-16) is associated with one of the contact pads.

Title: Display-dispenser for e.g. postcards - released from stack singly by coin operated switch which controls motor-driven belt, and strip lamp for illumination
IPC: G07F11/04
Filed: 1980-12-15
Abstract: The articles are held in a vertical stack for delivery to an outlet (4) one at a time in response to an exact number of revolutions of a motor (26). This drives a belt (27) rotating a pulley (25) on the end of an axle (21) carrying two resilient toothed wheels (19,20) and a curved flexible strip (24). The revolutions of the motor are counted by a control box (29) contg. a delayed relay and a monitoring relay linked to the linear displacement of the belt (27). The delay guards against rapid depletion of the stack by repeated operation of the control button (31), which is wired in series with the two relays and the motor. A strip light fitting (28) is supplied from the battery or transformer box (30). The switching of the motor and the light fitting is controlled by a coin actuated mechanism.
