Title: Solar panel using photocell array - has coupling provided via H-shaped connection tongues allowing defective photocell to be by=passed
Inventor: LOUBLY PIERRE
IPC: H01L31/05
Filed: 1981-03-20
Abstract: The panel has a series of photocells (10) embedded in a synthetic material which is sandwiched between two rigid sheets. The upper sheet is transparent. The photocells (10) are electrically coupled to one another via plated connection tongues (12,15). Each of the tongues (12,15) has two parallel limbs (11,13,14,16) coupled via a cross limb (18,19). One of the parallel limbs couples two adjacent photocells (10). The other remains disconnected during normal operation of the panel and has an insulating pad (17) at one end (13b), separating it from the corresponding branch (16) of the successive connection tongue (15). Pref. the end (13b) carrying the insulating pad (17) is linked so that it lies parallel to the end of the corresponding branch (16) at a distance above it corresponding to the thickness of the pad (17). The secondary limbs (13,16) allow a defective photocell (10) to be bypassed by removal of the pad (17).

Title: Electrode wire contact tube for arc welding machine - with protective sheath to prevent metal build=up
IPC: B23K9/12
Filed: 1981-04-09
Abstract: A contact tube guides and supplies current to the wire electrode in an arc welding machine. The tube is preferably copper, with a central bore through which the wire passes. The end of the tube facing the arc, and part at least of the sides, is covered by a protective sheath. This sheath is thermally and electrically insulating, and molten metal splashed from the weld pool does not adhere to it. The sheath is preformed from fibreglass based material, coated with a silicone based binder, and held in place by silicone glue. Protecting the outer end of the contact tube greatly reduces problems due to the build-up of splashed weld metal. This can interrupt the regular advance of the welding wire, and restrict the flow of a surrounding gas shield. Sec. arcs can also be set up between built-up metal and the part being welded. Preventing these means that contact tubes have to be changed less frequently, giving a useful cost saving.

Title: Two-part moulded watch support - is formed as U=shaped clip allowing watch to be worn on pocket, or used as clock
IPC: G04B37/14
Filed: 1981-06-15
Abstract: The watch support allows the user to wear its watch on the edge of a pocket, on the belt or to place it on a base so as to form a clock. The support is made in two moulded parts. The first part contains the watch and has a hole and two spigots. The second is fitted with a rod which is passed through the hole in the first part then its end is burred over so that the rod becomes a pivot. The second part also has two recesses corresponding to the two spigots on the first part so that the support can be kept closed. The support therefore forms a U-shaped clip which can grip a pocket or a belt.

Patent FR-2493829-A1 (FR)
Inventor: WALCHLI ERNST
IPC: C04B33/08
Filed: 1981-10-26
Abstract: Clayware with a porous body, in which the SO3 content of the body is at least 0.04 per cent by weight, relative to the weight of the dry fired body, and whose body is free of unconverted calcium oxide, and which clayware does not show any undesired calcium hydroxide efflorescence even under prolonged action of moisture, is produced by adding, immediately before forming, a sufficient quantity of an iron sulphide, especially pyrite, which is oxidised with formation of SO2 and/or SO3 at approximately the firing temperature of the clay material, to the clay material present as a plasticised raw mass and homogeneously distributing it therein. By means of this process, it is possible to overcome in a simple manner the difficulties which arise in the firing of clayware in gas-fired furnaces and to obtain clayware which is free of the undesired calcium hydroxide efflorescences which adversely affect the fired colour and the adhesion of plaster, which is of paramount importance in particular for brickworks products.
Patent FR-2518269-A1 (FR)
Title: Metal detector having one emitter and two receiver coils in head - producing complementary signals to differential amplifier in presence of metallic object such that constant output is maintained
IPC: G01V3/10
Filed: 1981-12-10
Abstract: The detector head articulated on a metal or plastic cone and connected by means of an electrical cable to a box containing the electronic and regulating equipment. The detector head consists of a sealed or non-sealed box containing three distinct coils. One coil serves as the emitter and is connected to an oscillator. The other two coils are receivers arranged such that a signal appears on each receiver when an oscillator signal is emitted by the emitter coil. Two receiver arrangements are possible. Either, in the presence of a large metallic mass, the signals issuing from the receivers diminish or augment simultaneously and are associated with a differential system so that the output voltage remains constant. Or, in the presence of a large metallic mass, the signal issuing from one of the receivers augments while the other diminishes and are associated with a summing system so that the output voltage remains constant. Each receiver has an amplification chain of identical gain, low noise, and high temp. stability.

Title: Solar energy collector.
IPC: F24S23/70
Filed: 1982-10-05
Abstract: The invention relates to the thermal utilisation of solar energy. Mutually parallel blades 4, with an upward concavity and inclined forwards, are arranged in a chamber which is limited at the front by a transparent wall 6 intended to be exposed to solar radiation. The shape of the blades 4, their dimensions and their arrangement allows an observer looking at an angle of -10 DEG to +10 DEG relative to the horizontal to see a light surface whereas, when the inclination of the rays from the sun is greater than +10 DEG relative to the horizontal, the rays are reflected at least once on an absorbent dark surface. Since the heat-exchange fluid is air, the most advantageous application is the heating of premises, and the heating of domestic water by means of an air/water heat exchanger.
