Abstract: 982,193. Semi-conductor devices. PHILCO CORPORATION. Feb. 20, 1962 [Feb. 20, 1961], No. 6510/62. Heading H1K. A semi-conductor device comprises a wafer of semi-conductor material mounted on a U-shaped thermally conductive block, the block being approximately coextensive with, firmly secured to, and in thermal contact with a face of the wafer with the arms of the block extending along the face of the wafer, and an electrical conductor joined to the face of the wafer and extending between the arms of the block. As shown, conductors 22E, 22B, 22C extend through a glass-filled metal header 10. A U-shaped block 11 of nickel-plated copper is soldered to the upper face 12 of header 10. A transistor comprising a square wafer 17 of semi-conductor material is provided on its upper face with a centrally placed emitter electrode 18E and an eccentrically placed base electrode 18B, while its lower face is provided with a centrally placed collector electrode. Fine conductors 21E, 21B, 21C are attached to these electrodes and the wafer 17 is joined to, but insulated from, the block 11 by means of a layer 24 of epoxy resin so that the ends of conductors 21E, 21B, 21C rest against conductors 22E, 22B, 22C respectively. Conductor 21C is arranged so that when the wafer is mounted it extends along the channel 16 between the arms of block 11 without making contact with these or with the top 12 of header 10. The ends of conductors 21G, 21B, 21C are spot-welded to conductors 22E, 22B, 22C respectively. A metal can (not shown) is placed over the assembly and is welded to the header to form a hermetic enclosure for the device. Block 11, header 10 and the can form a heat-sink for the device which may be further improved by providing further heat-sinks or heat-radiating surfaces on the header and cap. Block 11 may be made of a ductile metal such as copper, to absorb expansion stresses but a material with a coefficient of expansion close to that of the wafer 11, such as beryllia, may be used instead, and since beryllia is electrically insulating the wafer 17 may be soldered directly to a metallized surface of the block.

Title: Film guide means in roll film photographic cameras
IPC: G03B19/04
Filed: 1960-02-26
Abstract: 940,796. Roll-film cameras. R. HEIDECKE, and H. FRANKS, [trading as FRANKE & HEIDECKE FABRIK PHOTOGR.PRAZISIONS-APPARATE]. Feb. 26, 1960 [March 12, 1959], No. 6834/60. Heading G2A. The pressure plate 4 and a glass plate 2 of the exposure aperture of a roll-film camera are held by a stop pin 20 at an increased separation, when the camera back is closed, for entry of the thickened leader strip of a film 6, a film-wind locking pawl 12, which engages a recess in wheel 15 of the frame-counting mechanism 19-15 after sufficient film has been advanced, being then operative by means of its projection 31 to trip latching lever 27 and allow withdrawal of the pin 20 (under the pressure of spring 5 on the camera back) to give the normal width film channel. Pawl 12 is caused to unlock wheel 15 and ratchet wheel 11 by movement of a member 33 forming part of the shelter release mechanism, but the recess 29 on latch 27 is no longer opposite the arm 30 and this engagement is not re-formed until the back of the camera is removed, when spring 24 urges arm 30 in a clockwise direction in the absence of the pressure from spring 5. As shown in Fig. 2, arm 30 may also be rotated clockwise, so as to increase the depth of the film channel, by means of a screw 35. Although pin 20 applies pressure to the plate 4 at one point only, tilting of the plate is prevented by the double lever system indicated in Fig. 4 whereby a thrust against end 39 of plate 4 is transmitted, via levers 41, 42 pivoted respectively at 43, 44, to a bracket 47 carried on the other side of plate 4 so that the latter remains parallel to plate 2 during displacement. To this end also, additional features described in Specification 705, 902 are included. Specification 716, 773 also is referred to.

Abstract: 325,401. Siemens & Halske Akt.-Ges. Nov. 10, 1928. [Convention date.] Addition to 307,747. Coagulating.-The process of the parent Speci. fication is modified bv the use of a balanced alternating current of other than sinusoidal form. The modification of current form may be effected by the use of choke coils with or without iron cores, or condensers, or a combination of such elements, or by the superimposition of two alternating currents of different phase. The influence of the current form is greatest when effecting decomposition from a latex of relatively low concentration. In an example, a 10 per cent solution of latex is treated for 20 minutes with a 16 cycle alternating current obtained from a continuous supply by means of a rotating commutator, the voltage being 20 and the current density 20 milliamps per sq. cm. The yield was 2.4 gms. of rubber per watt, that with sinusoidal current being only 1.4 gms. per watt. With a 30 per cent solution of latex the yields per watt for the same period were 3.2 gms. and 3.1 gms. respectively.
