Patent FR-2503891-A1 (FR)
Title: Temp. control system with automatic compensation - for sensor feedback failure, for use with temp. sensitive moulding processes etc.
Inventor: TELIS ALEXANDR IOSIFOVICH
IPC: G05D23/24
Filed: 1981-04-14
Abstract: A temp. control system for maintaining a particular temp. profile by automatic adjustment for any algebraic difference arising between a set point temp. signal and a feedback signal from a temp. sensor on the equipment being controlled is complemented by an ancillary circuit to provide an alternative control system if the feedback temp. signal is interrupted by e.g. sensor breakdown. The ancillary circuit initiates an impulse signal to the heaters to maintain the controlled equipment at a temp. within the required operating range. Used esp. to temp. control of the barrel zones and/or moulds of an injection moulding machine, to eliminate the risk of material either freezing or overheating within the equipment depending on the response of the conventional control system to either isolate or to keep energised the unit heaters if the feedback circuit maintains a false or broken signal. Intervenes automatically until over-ridden manually following repair or purging of the equipment.

Title: Distributor for stack of thin wooden sheets - has pusher with alternating horizontal movement thruster which lifts stack for removal of lowest sheet
IPC: B65H3/02
Filed: 1981-04-16
Abstract: The equipment is for distributing flat, thin, wooden panels stacked on top of each other in a store bin. At the store base is a pushing element undergoing alternating horizontal movement. The pusher (11) slides under the stack of objects (1) and carries an attachment (17) in the form of a toothed plate, the top surface (18) of which is normally under the stack. Projections (19) lift the attachment relative to the pusher when it moves forward so that the top surface (18) presses below the lowest object in the stack to push it forward, free of the stack.

Title: Ferromagnetic parts aligning feed - has magnet pair around non-magnetic frame above tray
Inventor: ZUBOV EVALD KONSTANTINOVICH
IPC: H01F7/20
Filed: 1981-04-24
Abstract: The device for the properly aligned feed of ferromagnetic parts, e.g. to the pickup station of an industrial robot, consists of a guide tray (1) and a magnetic system (2) above it. A non-magnetic frame (6) of the same shape as the parts (7) to be aligned is placed over the tray. The magnetic system with the windings (5) consists of at least one pair of magnets on different sides of the frame relative to the movement of the parts. Like poles of the magnet system are arranged to face each other across the frame. This is a simple design of high functional reliability and produces a continuous flow of aligned articles.

Title: Dispenser for exchange of gas bottles using tokens - has roundabout moving in steps of compartment width with opening to permit exchange of bottles and detectors signalling cash desk
Inventor: RIDE CLAUDE
IPC: G07F11/54
Filed: 1981-05-19
Abstract: A rotating roundabout has several emplacements around its periphery which are filled except for one with full gas bottles. A crown wheel activated by a jack rotates the roundabout in steps. A steel cover over the bottles prevents their removal other than at a specific opening to allow a customer to obtain the full bottle in exchange for an empty one. The jack is controlled by a pneumatic distributor which also controls the locking jack whose shaft acts on the crown wheel. A probe verifies that the access door is closed while a second probe in series with it checks the presence of an empty cylinder after the exchange process. A third probe sends a validation signal to a cash desk.

Title: Telephone appts. with multiple, simultaneously usable handsets - has additional handsets disposed at back and on either side of subscriber telephone appts.
IPC: H04M1/06
Filed: 1981-07-20
Abstract: The base for telephone handsets is separated from the shell to which it is screwed in order to facilitate maintenance. The shell assembly has a drawer at the front to contain pencils and notes. The first additional handset is mounted to the rear of the normal handset and other handsets are mounted on either side. The line circuit switch in the cradle is operated in the normal manner by that handset. A transformer is used to obtain the same power in each of the earpieces, and has primary and secondary windings for each handset and microswitches which connect the appropriate winding into circuit as the handset is lifted. Back to back diodes on the secondary windings limit the amplitude of modulation superimposed on the signal by parasitic signals.

Title: Dishwashing machine with forced hot air drying - uses external contra-flow heat exchanger to transfer exhaust air to incoming air which is drawn in by fan and then heated
Inventor: DEISS ULRICH
IPC: A47L15/48
Filed: 1981-10-06
Abstract: The dishwashing machine draws in external air, heats it and directs it over the dishes in the dishwasher to dry them. The saturated air passes through a condenser to reduce its moisture content before it is exhausted to external atmosphere. The incoming air and the condenser are arranged as a contra-flow heat exchanger. The air is drawn in by an axial entry fan and directed up a pipe which is coaxial with the moist air outlet. The air pipe then turns downward and the air is admitted at the base of the dishwasher, passing over a heater as it enters. The warm air rises through the dish racks and exits from the top of the dishwasher to pass down the condenser pipe, giving up heat to the incoming air. The moisture falls down the condenser walls and is collected for disposal.

Title: Work-station for rapid manual assembly of printed circuit cards - has program-controlled light emitting diode matrix to illuminate desired printed circuit board holes for component location
Inventor: PECH GUY
IPC: H05K13/00
Filed: 1981-11-24
Abstract: The work station is designed to facilitate the location and orientation of circuit components in a circuit board matrix. The principle of the technique is to illuminate one or more circuit board holes (14) from underneath to allow the leads of a component to be correctly inserted rapidly without the need for reference to a circuit plan. The circuit board is positioned in a frame containing a matrix of holes (12) with are located under and are slightly larger than the circuit board holes. A corresponding matrix of light-emitting diodes (10) is positioned under the intermediate grid of holes and, when turned on, the light is guided through the circuit board hole. A keyboard-executable control program causes light-emitting diodes to turn on to indicate the positions of component leads, their total outline, or any other required feature, e.g. a flashing diode in indicate the position of a supply pin. A carousel of trays containing the various components to be inserted is positioned on the work station.

Patent FR-2520875-A1 (FR)
Inventor: LABRADOR JACQUES ALPHONSE LOUI
IPC: G01N21/90
Filed: 1982-02-01
Abstract: The invention relates to a process and device for detecting foreign bodies in a liquid, wherein the image of the apparent surface of the liquid in rotation in the immobilized recipients is formed, by reflection, diffraction, refraction or attenuation of the light coming from a source, on a matrix of reception and read cells. In the matrix each cell is perfectly delimited and its position is identified by numerization. A series of images is produced, of which a certain number are taken as reference and memorized. Each image is digitized and those images following the last memorized image is compared therewith cell by cell by a subtractor. The results of such a subtraction are compared with a threshold and results overstepping the threshold involve delivering a signal to a processor which controls a sort device arranged to eliminate undesirable units.

Patent FR-2505253-A1 (FR)
Inventor: LANDGRAF HELMUT
IPC: B29C48/09
Filed: 1982-05-06
Abstract: The invention relates to a device for coating steel pipes with tubular films of thermoplastic, in particular polyethylene, the steel pipes being first guided through a subatmospheric chamber and then through an extruder head connected thereto and serving to produce the tubular films and, by means of the subatmospheric chamber, a subatmospheric pressure of between 450 and 550 mm water head being maintained in the interspace between the pipe surface and the tubular film emerging from the extruder head. To prevent undesired deformation of the tube or tearing thereof, this resulting from sudden changes in the subatmospheric pressure between the pipe surface and the extruded tube, it is proposed that the pipe inlet opening (11) of the subatmospheric chamber (2) have a diameter which is 0.5-1.5% greater than the nominal diameter of the pipes to be coated. Individual developments are given in the subclaims.
