Filed: 1969-11-18
Abstract: 1291983 Welding by fusion and pressure WESTERN ELECTRIC CO Inc 18 Nov 1969 [19 Nov 1968] 56376/69 Heading B3R Workpieces are joined together by applying radiant energy to a portion of the contiguous workpieces while simultaneously and substantially instantaneously applying a compressive force to the workpieces. As shown in Fig. 1 the contiguous surfaces of workpieces 12, 13 which are made of highly conductive material such as copper or aluminium are heated and melted by radiant energy in the form of a laser beam 14. A pancake coil 17 has electrical energy supplied to it to develop a high density magnetic flux 18 concentrated by a metallic flux concentrator 19 which interacts with fields produced by induced currents within the workpieces 12, 13 thereby creating a pressure upon the workpieces toward the work-table 11 and bonding takes place. In another embodiment, Fig. 2, tubular workpieces 21, 22, one within the other, are joined in a similar manner in which a helical coil 17<SP>1</SP> is positioned within a cylindrically shaped flux concentrator 23 and one or more beams of radiant energy 26, 27 are directed on to the contiguous portions of the workpieces to effect bonding. In a further embodiment, Fig. 3 (not shown), tubular workpieces to be bonded, one within another, are placed in a cylindrically shaped flux concentrator which is placed within a helical coil, and the beam of radiation is directed on to the contiguous portions of the workpieces. In the case when the workpieces are made of a low conductivity material an overlay composed of a high-conductivity material is placed over the contiguous portions to be bonded so that currents may be induced in the overlay which places a compressive force upon the workpieces. The overlay is provided with an opening for passage of the radiant beam. An electric system is provided for facilitating the simultaneous pulsing of the laser device with the generating of the magnetic field. The invention is used in connection with semi-conductors and thin film integrated circuits.

Title: Photographic or cinematographic camera with low light signal
Inventor: BRESSON RICHARD JOSEPH
IPC: G03B7/00
Filed: 1968-11-28
Abstract: 1,253,985. Camera low-light-level-indicator. EASTMAN KODAK CO. Nov.28, 1968 [Dec. 6, 1967], No.56525/68. Heading G2A. A camera has a first sensing lever responsive to a film sensitivity code provided on a film supply, a second sensing lever responsive to the position of a transducer member positioned as the result of the level of scene illumination incident upon photo-responsive means, and an indicator responsive to the positions of the first and second sensing levers for indicating whether the level of illumination is above a value determined by the film sensitivity code. The position of a diaphragm aperture control lever 36 is determined, on the left by a) a code sensing mechanism; including a lever 19 and lug 17, the code being the position of a slot 12 in the cassette 11, b) by a manual shutter time control knob 24, and on the right by a mechanism which locks and then senses the position of a galvanometer needle 59 coupled to a photo-cell. The code sensing lever 19 also positions a lever 83 according to film sensitivity and hence a contact 76 in a signal circuit. On operation of a shutter release button 53 a lever 55 pivoted at 56 rotates clockwise raising a cam member 49 with a needle clamping member 63, slidably attached. A toothed surface 67 of the clamping slide 63 engages the needle 59 and locks it, while cam member 49 continues its upward movement until its cam surface 68 engages the trapped needle 59. Thus the position of the diaphragm aperture control lever 36 is set according to the scene illumination. If the needle has not been clamped when a pin 37 on the lever 36 reaches the top of a slot 38, i.e. at full aperture, the lever 36 pivots about the pin 37 to move the shutter speed setting lever 25 downwards, thus over-riding the manual setting. The low-light-level signal lamp 73 operates if the member 49 moves vertically sufficiently far for the contact to be made between parts 77 and 79. This occurs when the needle 59 is located at the right of the slot 61. Contact is made and the signal, comprising a lamp in the view-finder or a buzzer, operates before the shutter release button 53 has progressed sufficiently far downwards to operate the shutter by means of a pin 71 contacting a lever 72. The lamp may be replaced by a buzzer. Alternatively the camera might include a flag member movable to a warning position in response to movement of clamping member 63 relative to adjustable slide 77.
