Abstract: 802,415. Centrifugal strainer separators. DEMOISY, A. P. A. Jan. 10, 1957, No. 1028/57. Class 46. A continuously operating press especially for expressing juice out of mare comprises a centrifugal strainer drum with a perforated surface 1 and an inner rotor rotating with the drum but at a different speed, the rotor having aligned compartments the end compartment containing positively driven endless track presser members urged by centrifugal force against material to be treated and the other compartments frictionally driven cylinders, the material being retained by the perforated wall of the drum while the liquid passes through. Spiders 2, 3, one rigidly mounted on a shaft 7 and the other, through ball bearings, on a hollow shaft 6 enclosing the shaft 7 support the drum while the rotor is rigid with the shaft 6 and is driven by their common driving motor 9 at a speed slightly different from that of the shaft 7. Marc from a hopper 15 is fed by a screw conveyer 16 to the drum and passes therealong, movement across compartments defined by radial partitions 22 being aided by spiral guides 25. In at least the end compartment are endless track presser members, each comprising a heavy woven stainless steel track 26, Fig. 5, made rigid transversely by steel bars and passing loosely over driven rollers 28 and rollers 29 mounted on arms 30 pivoted on the axes of the rollers 28 to cause the tracks to move outwards under centrifugal force. A lightweight track loaded with heavy rollers may be used. The rollers 28 are geared to pinions rigid with the hollow shaft 6. In the other compartments, diametrically opposite pairs of rollers are frictionally driven to press the material. An outer casing 20 enclosing the drum is provided in its bottom portion with a liquid discharge outlet 21; solids are directed by a guide 18 into a delivery chamber having a discharge shoot 19.

IPC: H01L21/607
Filed: 1961-01-13
Abstract: 916,193. Semi-conductor devices. SIEMENS & HALSKE A.G. Jan. 13, 1961 [Jan. 14, 1960], No. 1518/61. Class 37. Connections between the electrodes on a semi-conductor body mounted on an insulating support, and two supply leads also mounted in or on the support are established by securing each of two connecting wires to a separate one of the electrodes and both supply leads and then severing the wires so that each electrode is connected to only one supply lead. The arrangement can apply to two groups of electrodes instead of two single electrodes. In Figs. 1 and 2, guides 3 stretch wires 1 and 2 over supply leads 7 and 8 and closely spaced electrodes 4 and 5 on semi-conductor body 6. Knife-like tools 9 press the wires into contact with the leads and electrodes and are heated to effect thermocompression bonding. One wire is then cut between lead 7 and electrode 4 and the other between lead 8 and electrode 5. The wire preferably consists of gold or gold alloy, and bonding may be carried out in a protective gas. In a modification each wire is connected to a plurality of electrodes constituting one group, so that finally all the electrodes of a group are connected to one supply lead. The arrangement is particularly suitable for the manufacture of mesa transistors. The wires may be stretched over a plurality of semi-conductor arrangements for multiple production.

Title: Apparatus for the production of zinc oxide
IPC: C01G9/02
Filed: 1931-01-16
Abstract: In the production of zinc oxide by combustion of vaporized zinc, each retort or crucible for evaporating the zinc is connected to a separate combustion chamber and depositing device, and the latter comprises two or more parts provided with means for putting any part out of operation if desired.  As shown in the Figure, zinc vaporized in a retort 3 is oxidized in a combustion chamber 4 by air supplied by a blower 6 from the furnace flue 2, whereby the heat of the waste gases from the furnace 1 is utilized.  The zinc oxide is drawn by an exhauster 9 through cooling chambers 7, 8 to bag filters 11.  At the beginning of the operation when the zinc oxide is contaminated with cadmium oxide, it is collected in the group of filters A, the pure zinc oxide later obtained being collected in the filters B. Alternatively by removing the im <PICT:0360746/III/1> pure oxide from the filters A, all the filters may be used for collecting the pure oxide.  The oxide obtained towards the end of the operation may also be collected separately.

Title: Improved automatic ultrasonic inspection apparatus
IPC: G01N29/38
Filed: 1956-01-17
Abstract: 787,217. Ultrasonic inspection devices. SPERRY PRODUCTS, Inc. Jan. 17, 1956 [Jan, 20, 1955], No. 1608/.56. Class 118 (2). In an ultrasonic pulse-echo flaw detector for recording echoes 7, Fig. 3, I, from defects D within a predetermined zone below the front surface 17 of the workpiece 16 which is immersed in a coupling fluid in a tank T, the echoes are applied to the recorder through a normally closed signal gate 27 which is opened by a gating pulse H of duration (T4-T6) initiated a predetermined time interval (T3-T4) after the time T3 of receipt of the echo pulse 6, Fig. 3, I, from the surface 17 so that the position of the zone relative to the surface 17 is independent of variations between the transducer 15 and the surface 17. As shown, the pulse output A from a generator 10 triggers a wave-pulse generator 11 (output B) coupled to the transducer 15 which is also coupled through a pre-amplifier 20 in parallel to an "interface gate" 26 and to the signal gate 27 whose output J is "stretched" at 31, modulated at a low frequency at 32 and applied to the recording pen motor 25 and through a normally open gate 50 to an aural alarm 51; the gate 50 contains a voltage discriminator to prevent sonic noise from actuating the alarm. Another output A from generator 10 triggers a delay multivibrator 12 whose output C initiates in generator 29 a gating pulse D which opens the interface gate 26 to select the echo 6 from surface 17 which terminates pulse D and initiates in generator 30 a sawtooth waveform N which is applied to discriminators 40 and 41 together with D.C. bias voltages M and L from potentiometers 46 and 47 which may be adjusted manually or by servos 48 and 49. The output pulse G from discriminator 40 occurring at time T4 initiates in generator 45 the signal gating pulse H which is terminated at time T6 by the output pulse K from discriminator 41. In order to test the equipment, the generator 45 is periodically triggered at a time T2 giving a signal gating pulse O instead of pulse H which allows the echo 6 from surface 17 to be recorded. This is effected by applying trigger pulses A to a normally closed gate 64 which is opened by a control pulse from a generator 63 triggered by a cyclically-operated mechanical switch 60.. The first trigger pulse A after operation of switch 60 terminates the control pulse and is applied through delay 65 (output E) to trigger generator 45 and is also applied to trigger a monostable multivibrator 70 whose output P closes the alarm gate 50. Alternatively testing is effected by adjusting bias voltage L so that the signal gate 27 passes the echo 8 from the bottom surface 14 of the mouthpiece.
