Patent FR-2426103-A1 (FR)
IPC: D03C1/14
Filed: 1979-05-18
Abstract: The force-transmission part of such a dobby contains, for each heald frame, a pair of hooks (4) arranged in one plane. Each hook (4) is assigned a double-armed lever (2) which is mounted pivotably on rods (1) and of which the pivoting out in one direction is caused by a spring (12), by the hook (4) and by a fixed support (5) and in the opposite direction is limited by a stop (3). Mounted on one arm (200) of the double-armed lever (2) is a pair of horizontal needles (8, 9), of which one needle (9) carries a sensing needle (18) of the new weft and is held by a straightedge (11) of the new weft, whilst the other horizontal needle (8) carries a sensing needle (17) of the old weft and is held by a straightedge (10) of the old weft. The horizontal needles (8, 9) are lifted by an auxiliary straightedge (15). The double-armed levers (2) are blocked in their pivoted-out position by a retaining straightedge (16). As a result of this arrangement, an exchange of the functions on the straightedges (10, 11) is achieved during the return motion of the weaving machine, so that the sequence of movement is reversed relative to the original sequence of movement and consequently no additional rotation of the pulse device in the idling mode is necessary before restarting.

Patent FR-2465866-A1 (FR)
Title: Linear motor sliding bridge braking system - is controlled by sensor detecting gap closure speed from progressively spaced markers on bridge
IPC: E05F15/60
Filed: 1979-09-25
Abstract: The appts. uses a series of markers, near the ends of the bridge, disposed in a horizontal line and separated by decreasing intervals towards the ends of the bridge. A fixed detector senses the passage of the markers to provide an instantaneous indication of the speed of the gate during the end of its opening or closing cycle. The detector commands the braking of the bridge, by inverting the polarity of the supply to the linear motor, as a function of the measured speed. This permits the time taken for the bridge to travel the distance separating two consecutive markers to remain essentially constant. The detector is such that it commands the braking when the time taken between two consecutive markers is below a threshold, but ceases to command the braking when an upper threshold is reached.
Patent FR-2438419-A1 (FR)
IPC: A01K1/06
Filed: 1979-10-09
Abstract: The self-locking device for securing livestock in a livestock stand has two panel-shaped retaining members (5, 6) which are fastened around a horizontal, pivotable tube (1). Said retaining members (5, 6) are aligned with each other in the axial direction of the tube and are spaced apart from each other by a locking slot (7) which widens inwards from the outer side of the retaining members. One of the retaining members (6) is provided with a pocket (11) between the two panels of the retaining member (6) for receiving a blocking disc (10), which is mounted, such that it can move slightly, in the pocket (11) and, in the locking position of the device, closes off a blocking region on the mouth end of the locking slot (7) by the force of gravity. A tether (8), e.g. a tethering rope, fastened on the neck of the animal to be secured is able, when the animal enters into the stand, to push the blocking disc (10) inwards into the locking slot (7) and thus, itself, to pass into said slot. The blocking disc (10), falling back into its closed position once again after passing the slot mouth, fixes the tether (8) in the locking slot (7), and the animal is thus secured. By pivoting the retaining members (5, 6) up, the blocking disc (10) falls back into the pocket (11), the tether (8) coming out of the slot (7) and the animal being able to free itself from the self-locking device.

Patent FR-2443201-A1 (FR)
IPC: A01K85/01
Filed: 1979-12-04
Abstract: The bait has a body (1) which is flat and in the shape of a fish and is provided with fish-hooks (3, 7). In use, the bait is pulled through the water. A guide blade (2) protruding out of the bait body (1) obliquely with respect to the direction of pulling causes the bait to vibrate approximately perpendicularly with respect to the direction of pulling. This vibration produces a noise which is attractive to fish and is effective in a radius of 30 to 50 m. The vibrations also increase the visual attraction effect by a flashing effect which is produced by light-reflecting surface regions on the bait body.

Title: Heater for forced circulation of air through bakery oven - has interchangeable module comprising heater and heat exchanger
IPC: A21B3/00
Filed: 1980-02-05
Abstract: The air heater comprises a blower unit employing one or more fans. The suction side of the blower unit is connected to the upper part of the oven. The blower unit recycles the air into the top of a duct extending down through an indirect heat exchanger, which has a low level outlet leading into the lower part of the oven. An interchangeable heater fits removably into a chamber inside the heat exchanger casing. The heater is designed to be withdrawn via a removable side panel of the casing. The panel is bolted or clamped over the heater access port which is surrounded by a compression seal to be sandwiched between panel and casing. Inside the casing, opposed side walls at right angels to panel are pref. fitted horizontal support slides. The leading end of the heater than has a transverse bar of which the ends rest on the slides. The indirect heat exchanger may be of the multi- plate type. The heater may employ a gas/oil burner or may use electric resistance heating elements. The heater is easily removable to facilitate cleaning and maintenance of the heater itself, the heat exchanger and the interior of the casing. It is now simple and inexpensive to convert from gas or oil firing to electric heating and vice verse.

Title: Domestic hot water system with auxiliary solar heating - uses immersed coiled tube, central heating water jacket on tank and thermostatically controlled element
Inventor: HERAUD ROBERT
IPC: F24D19/10
Filed: 1980-03-06
Abstract: The domestic hot water installation combines heating from solar panels, from a central heating boiler and from an electric heating element in the base of the storage tank. Solar panels (2) heat the water through a coiled tube (13) inside the insulated (17) tank (8). Water from the fuel fired boiler (5) heats the water further by passing around the space between the double skins of the boiler (16). When neither solar heating or central heating is operating sufficiently, a thermostat (30) in the lower part of the tank controls the electricity supply (20) to the heating element (31) to bring the water to the required temperature.

Title: Distinguishing method to find precious stones in small sample
IPC: G01N25/18
Filed: 1980-03-28
Abstract: Thermal conductivities of materials are compared using very small quantities in order to distinguish the precious stones without destroying them. This is performed by use of a thermocouple which is pressed into contact with the material after being heated. A thermal comparator comprises a thermocouple which is formed from two lengths of glazed constantin wire (10) and a short length of copper wire (11). A conical copper head (12) of small volume is welded to one junction and is pressed in use against the material sample. The copper wire and the two junctions are contained in a PVC sleeve (13) which slides in a glass tube (14). The constantin wires are glued (15) to the inside of the glass tube to form a spiral over part of their length. The ends of the wires are connected to a numerical millivoltmeter with high revolution.

Title: Recovery of waste heat from bakery oven etc. - provides washing water at controlled temp. and used for space heating
IPC: F27D17/00
Filed: 1980-05-19
Abstract: An exterior surface of the oven chamber transfers heat to an adjacent reservoir of heat transfer fluid partic water supplied from the mains via a valve. The heat transfer water is pumped around a primary circuit contg a heat exchanger coil immersed in a tank supplying service hot water for cleaning duties. In the primary circuit, upstream of the heat exchanger coil, a three-way valve can divert the flow to by-pass the coil and return water directly to the reservoir without passing through the coil. The pump is pref installed in the circuit upstream of the coil by-pass value. The coil by-pass valve is pref operated automatically w.r.t the temp of service water delivered by the heat exchanger tank. The primary circuit pref has a branch to a pressure accumulator vessel with pressure gauge and preset relief valve. Between the reservoir and the pump, a shunt circuit is pref provided to supply space heating radiators etc. The installation makes use of heat previously wasted from the exterior of high temp ovens, partic bakery and patisserie ovens.
