Title: Feed device for pigeons and fowls - has perforated feeding plate and storage hopper with overhanging lid
IPC: A01K39/012
Filed: 1973-11-12
Abstract: The feed device consists of a trough covered by a perforated plate which protects the food from dirt and prevents it from being scattered by the birds, who feed through the apertures. The storage hopper only allows replenishment of the trough as the latter is emptied. The tipping hopper cover overhangs the trough, protecting it from the weather. The apertures only allow the passage of the heads of the birds and allow a row of brids to feed simultaneously.
Patent FR-2324888-A1 (FR)
Title: Fuel supply stabiliser for IC engines - has overflow system to return excess fuel or vapour to fuel tank
IPC: F02M37/20
Filed: 1974-01-11
Abstract: The carburettor (c) is supplied by the electric motor driven pump (1) which draws petrol from the tank (R). The velocity of the fuel in the pipe is reduced in the vessel (4) of relatively large diameter compared with the pipe. Excess fuel is allowed to overflow into the atmospheric vessel (P) which returns the fuel to the tank through the pump (L). Petrol vapour may be drawn off from the vessel (V) and condensed and returned to the fuel tank through the atmospheric tank (P). The system ensures a constant supply of fuel independent of high acceleration or braking.
Patent FR-2267531-A1 (FR)
Title: Sunlight actuated solar house heating panel - swings down to reflect heat inside, swings up to prevent heat loss
IPC: F24J2/04
Filed: 1974-04-12
Abstract: An extension (4) of the north facing half of a conventional sloping roof is closed by double glazed vertical wall (3) facing south, inside which is a large flap (8) which can be swung down parallel to the vertical wall or swung back parallel with the sloping extension. This flap is reflective on the side facing the double galzing, and when swung back, reflects sunlight passing through the double glazing onto a horizontal black body (10) forming the ceiling of the rooms (11) underneath. Thus heat from the sun stored in the ceiling can be circulated afterwards around the rooms below. This flap can be controlled by a photoelectric detector so that it prevents loss of heat when the lighting is below a given level.

Title: Information recorder using electrosensitive metal paper - has group of individual writing electrodes electrically insulated from one another and separately controllable
IPC: B41J2/425
Filed: 1975-02-21
Abstract: The information converted to analogue voltages is fed to an analogue-digital converter. A first quantity of binary number outputs in the converter synchronously control the outputs of at least two demultiplexors. A second set of binary number outputs control the release inputs of the demultiplexors whose outputs regulate the writing electrodes. A cyclic frequency is provided for the analog-digital converter whereby at each cycle, the analog voltage is converted into a binary number. The number of demultiplexer outputs amounts to 2x while the number of demultiplexors for controlling the writing electrodes amounts to 2Y. The design enables the control process of one writing electrode to be independent of that of another electrode.

Title: Printed teletypewriter paper automatic rolling system - employs oscillating arm over which paper passes to rotating cylinder
Inventor: BELIN JACQUES
IPC: H04L13/06
Filed: 1975-06-30
Abstract: Automatic winding of the printed paper from a teletypewriter is performed using a rotating cylinder with an oscillating arm over which the paper passes before winding onto the cylinder. A micro switch operated by the arm controls the motor and eliminates tearing of the paper. A chassis (2) with two mounting holes (3) carries two arms (5, 6) over which the paper from a teletypewriter passes. One arm (5) can articulate about an axis (7) but is fixed by a shoulder (8) while a second arm (6) oscillates around an axis (9) parallel to the first axis (7). A spring (10) provides a lifting torque on the arm. Paper passing over the arms is wound onto a cylinder (13) driven from a motor (21) with a microswitch in its power supply circuit and which is operated by a finger (33) on the lower arm axis (9).
Patent FR-2273887-A1 (FR)
Title: Thermoplastic filaments and films prodn. - by heating extruded prod at above glass transition temp. while causing shrinkage, and cooling
IPC: B29C48/92
Filed: 1975-09-11
Abstract: A process is claimed for producing filaments and films by incorporating a porogenic agent into a thermoplastic polymer, extruding the polymer melt, subjecting the extruded filament or film to a thermal treatment at >=100 degrees C above the Tg of the polymer while causing >=10% longitudinal shrinkage of the material, and finally cooling the polymer. Porous filaments and films are obtd. without blocking of the extruder die or nozzle, rupture of the extrudate or collapse of the pores occurring as in prior art. Further, by treating the filaments or films prior to the thermal treatment, e.g. with an aqs. soln. of a salt or with functional agents, these can be made to penetrate the pores inside the material to subsequently resist elimination by washing.

Title: Laundry item and garment label marker - comprises holder and marking stencil strip with tape clamped between them
IPC: B65C5/00
Filed: 1976-05-25
Abstract: A device for marking items of laundry, or for making laundry marks on e.g., label tapes, consists of a set of letters and figures on a strip of material such as synthetic resin for which there is a holder. At the ends of the holder there are transverse slots for the passage of the tape to be marked, and along its vertical flanges the holder has teeth directed inwards to guide the letter set strip. The transverse slots to admit the tape open out conically downwards into a recess for the tape, and the face of the holder and of the stencil with which the tape makes contact is roughened. Beneath the guide teeth, openings are provided to facilitate release from the mould and the slots forming the letters widen out towards the top to admit the tip of a ball pen. The first and last letters of the marker strip are positioned about an inch on, so that the marker is held securely. The device holds the details more securely together. The tape can easily be drawn through and cut off to length.

Title: Time delayed alarm system - is for household or vehicular use and has two circuits having independent time delays
IPC: G08B13/00
Filed: 1976-11-09
Abstract: The system is designed to actuate a sound or other type of alarm with two independent time delays. The system is supplied from two series contactors which are associated with two relays and two independent electronic circuits. These circuits permit change of state of the contactors with a time delay after connection of the voltage supply. The second contactor (X2) can only change its state after the first contact (X1) has changed state, and applied voltage to its electronic control circuit via a relay. Each contactor after changing state cuts the supply to its own winding and to the electronic circuits which controls it. The two relays ensure the zero reset of the time delay of the electronic circuits.
