Patent FR-2017413-A1 (FR)
IPC: B26F3/00
Filed: 1969-08-21
Abstract: 1,271,734. Breaking. TEXAS INSTRUMENTS Inc. 23 July, 1969 [5 Sept., 1968], No. 37107/69. Heading B3E. A method of removing from transistor headers 1, by suction forces, pigtails 9a and 11a of wire remaining after wires are stitch bonded to the ends of leads 13 and 15 of the headers comprises placing a bar 23 on a carrier 53 over two rows of headers 1 so that the headers are received in two slots 27. Ribs 29 on opposite sides of the slots bear down on the rims 3 of the headers and clamp them down against the carrier 53. With vacuum applied to a vacuum head 31, the head is reciprocated back and forth in rapid short strokes, starting at one end of the bar 23 and gradually progressing to the other end of the bar. As a result the lower end of each suction port 47, 49 and 51 is repeatedly moved into and out of proximity to the pigtails 9a and 11a which causes repetitive bending of the pigtails at points adjacent the stitch bonds 21. This is continued until the wires become sufficiently work hardened to break off after which they are sucked up and trapped in the head.

Title: Steel plate connector for timber structures - has plate with multiple teeth of differing shapes pressed out
IPC: F16B15/00
Filed: 1974-04-18
Abstract: A design of muld steel plate joint is described, intended for joining timber structures of buildings. The plates span the joint on opposite faces of the timber and have a series of teeth pressed out at right angles to penetrate the wood and maintain the joint. There are three basic tooth forms, teeth (A, B) intended to resist sliding and shearing whilst at the same time teeth (B, C) providing for easy location on assembly. The teeth (B and C) are long and narrow and teeth (A) are at an angle to the grain, so that assembly by simple rollers is possible. The progressively shorter teeth (C) at the extremities of the plate also assist the method of assembly by rollers.

Title: Propulsion engine using kinetic energy - has flywheels on wheel spokes which rotate half turn over small arc of wheel
IPC: F03G3/08
Filed: 1974-09-04
Abstract: A main shaft (2) carries a number of spokes each carrying a spindle parallel to the shaft. Each spoke carries a rotating mass (1), revolving at very high speed around its spindle. The masses also revolve around axes in line with the radii of the assembly. This last revolution takes place while any mass (1) travels over the arc (6). Also this last revolution is only over 180 deg. so that the direction of rotation of the mass (1) is effectively reversed over the quadrant (6). The resultant force is in the direction (7). By varying the reference to the arc (6) the direction of the resultant (7) may be modified.

Title: Ozone generator with glass body - having lead plate sealed in glass and second plate to form arc
IPC: C01B13/11
Filed: 1974-10-01
Abstract: Ozone generator consists of metal (Pb) plate connected to a high voltage pole is enclosed between UV resistant glass sections. Above the glass surface at a distance 'a' are two other plates which are connected to the other pole of the high voltage source. When power is applied, the gap 'a' is such that arcing occurs between the plates. Through this gap an air stream is passed and the arcing causes the formation of O3 in the air, giving an O3 enrichment. Of particular application for ozonisation of small, esp. domestic, swimming pool installations.

Title: Electrodynamic transducer with movable system - designed for servo follower loop for optical reading of disc recordings (NL150676)
Inventor: MALISSIN ROLAND
IPC: G01R5/10
Filed: 1974-12-13
Abstract: The movable system has a conducting winding immersed in a magnetic field received by the winding in rest state. It has a zone of uniform intensity and monotonically decreased in the movable system direction of movement, with the decrease corresponding to the distance of the system from the rest position. The movable system has at least one additional conducting winding allocated to a current source. At least a part of this winding is the decreasing zone of magnetic field. Direction of current in this winding is such, that it tends to move the movable system away from the rest position. The system has a device generating a force opposite to the electromagnetic force.

Title: Automobile wheel seating appts. - checks camber angle using pivoting projector and receiver
IPC: G01B11/275
Filed: 1974-12-17
Abstract: For each wheel there is a projector and a reflector plate which takes up the same position as the wheel to be controlled. The projector is associated with a receiver which is sensitive to its radiations and is turned by electronic control, itself controlled by the sensitive element. This signals the angle concerned, or the angle between two wheels which are on the same axle. The receiver is turned with the projector and is only exited when reflected radiation from the projector is perpendicular to the reflector plate, the receiver activating the angle measuring device.

The movable portion has two sections unfolding from a horizontal position into a vertical one and in the outwards direction. The sections are complementary to each other, being inscribed in a rectangle when folded. They are concave, to accmodate the furniture, and there are four pneumatic compensators at the corners, mounted near the hinges. The tops of the complementary sections are joined to a roof by lengthwise hinges, one on each side.
Patent FR-2306267-A1 (FR)
Title: Steel making furnace lined with carbon bricks - and having water cooling elements giving lower wear rate
IPC: F27D1/12
Filed: 1975-04-02
Abstract: Steel making furnace comprises a base with a wall mounted on it to define the melting chamber, partially lined internally with carbon bricks such that the lower edge of this part of the wall is located upwards at a predetermined distance from the layer of slag formed on the surface of the molten steel, water cooling elements being embedded in the wall in carbon brick lined recesses. Used esp. for steel furnaces using scrap steel. The water coating reduces the local temp. of the carbon due to its high thermal conductivity thus reducing the tendency to oxidise, allowing improved resistance to erosion due to molten metal oxide resulting from the injection of metal and inevitable frequent interruption.
