Abstract: 926,077. Semi-conductor devices. TOKYO SHIBAURA ELECTRIC CO. Ltd. July 28, 1961, No. 27583/61. Class 37. Apparatus for sealing a semi-conductor element in a housing comprises holders for the element and for the housing which are slidably mounted in a sleeve, the sleeve and holders defining a chamber which is continuously fed with clean dry gas. Fig. 1 shows the sealing apparatus. The semi-conductor element 35 is mounted in the end of chuck 28 slidable in stem holder 22 which is slidable in sleeve 16. A spring 32 holds lead wire 34 which extends from the semi-conductor element 35. The housing or shell 25 for the semi-conductor element is mounted in the end of shell holder 21 which is also slidable in sleeve 16. The sealing operation is performed by pressing down stem holder 21 so that element 35 is suitably situated in shell 25 to which it is sealed by projection welding, cold welding, cold soldering or other known process. The sealing process takes place in the presence of a gas such as oxygen, nitrogen or air which flows from inlet pipe 18, pipe 17, recess 33 to the space around the element and its shell and then out via tube 20. Mass production may be effected by means of an intermittently rotating table 37 (Fig. 2) carrying a number of elements 10 each as shown in Fig. 1, which are manually or automatically loaded with shells and semi-conductor elements in their stem holders and then rotated to the sealing station where a press means 40 depresses the stem holder as previously described, to allow hermetic sealing to proceed. The gas supply comes from a central valve 40 via distribution tubes 38. The operation is completed in half a revolution.

Filed: 1962-07-19
Abstract: 974,065. Transistor amplifying circuits. COMPAGNIE FRANCAISE THOMSONHOUSTON. July 19, 1962 [July 21, 1961], No. 27836/62. Heading H3T.  In an amplifier including a transistor from which an output is obtained across a pair of its electrodes, the gain is controlled by varying the current flow between, and the voltage drop across the pair of electrodes, the variations being so correlated as to maintain the input and output impedances of the transistor substantially constant with changes in gain. As described, Fig. 4, an amplifier comprises three similar stages each supplied with a gaincontrol voltage, which may be automatic gain control, from a source P. Stage 1, for example, comprises a common emitter transistor T1 having an inductive load L11 which includes a winding n1 connected in a stabilizing feed-back path to the base. The control source P has a first output A connected to vary the base potential, and hence the collector current, of T1 and a second output B connected to the collector via resistor R14 to vary the collector potential. By adjusting the values of R41, R42 the ratio of the voltage at A to that at B may be arranged so that variation of gain of the transistor T1 is achieved without substantial variation in input and output impedances of the transistor.

Title: Improvements in cigarette weighing machine
IPC: G01G19/00
Filed: 1953-10-14
Abstract: 732,821. Weighing apparatus. AMERICAN TOBACCO CO. Oct. 14, 1953 [Oct. 17, 1952], No. 28332/53. Class 143. [Also in Group XXXVIII] In a cigarette weighing machine cigarettes in a hopper 2-3, Fig. 2, are fed singly by a grooved roller 4, rotated at constant speed, into notches 17 on the bifurcated end 16 of a balance beam 13, the cigarettes being released from the roller under gravity by a trip plate 9, rocked to the dotted position at the appropriate release times. After each weighing, an ejector arm 18 is rocked about its pivot 19 to lift the cigarette from the balance so that it rolls down the ejector arm on to a travelling belt 20. Weighing and recording. The balance beam is deflected as a cigarette falls thereon against the bias of a spring 23 and moves correspondingly the armature 31 of a differential transformer 28. Oscillation of the beam is prevented by dash pots 24. The similar secondary windings 30 of the transformer 28 are connected in opposition to similar opposed primary windings 36 of a second differential transformer 34, Fig. 1, the armature 37 of which is carried by an arm 39 pivoted at 40. The primary of transformer 28 is fed with A.C. so that the secondary 35 of transformer 34 yields an output dependent in magnitude and phase sense on the relative positions of the two armatures in their respective coils. The output is zero in the neutral position of the balance beam. As a cigarette is fed on to the beam an output is derived from the secondary 34, amplified, and after passing through a phase discriminator, fed to a two phase motor 43, Fig. 4 (not shown), which through gearing drives a cam 47 to rock the arm 39 and move the armature 37 until electrical balance is achieved. The angular position of the motor shaft which is a measure of the weight is translated by a cord 50 driven by a pulley 49 into a corresponding linear position of a recording pen 53 across a chart C carried in a frame 52, the pen being controlled in known manner to make a record mark on the chart as electrical balance is achieved. The chart is raised in timed steps through a ratchet, pawl, and pinion-rack device, Fig. 5 (not shown), by a spring stressed by a solenoid energized by the trip-plate 9, Fig. 2, as it is rocked to release a cigarette on to the balance. When a cigarette is ejected from the balance beam after being weighed the balance beam and hence the recorder return to neutral before the next cigarette is fed on to the balance.
