Title: Improvements in and relating to transistors
IPC: H01L21/00
Filed: 1958-05-30
Abstract: 873,005. Transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 30, 1958 [May 31, 1957], No. 17333/58. Class 37. In a transistor comprising a high amplification factor collector electrode the semiconductor base body decreases in cross-sectional area and conductivity from the emitter to the collector. In the embodiment, Fig. 1, a small areaalloyed junction emitter 9and a surrounding, ring-shaped ohmic base connection 11 are disposed on the large face of a tapering N-type germanium or silicon body 2 and a PN type hook collector 3, 4, on the small face directly opposite the emitter. A base zone resistivity increasing exponentially with distance from the large face of the body is provided by vapour diffusion of donor material into this side of the body. The resistivity gradient gives rise to a drift field and the tapered shape of the base zone to a drift field and a radial focusing field both of which tend to accelerate minority carriers (holes) across the base zone, thereby reducing the transit time and ensuring rapid removal of stored carriers from the base zone. The radial field also tends to restrict emission to the flat central region of the emitter junction over which the injection efficiency is greatest and substantially constant. In its absence a substantial fraction of the emitter current would flow through the edges of the junction where the injection efficiency is lessened on account of the steep resistivity gradient in the base zone at this point. Specification 842,103 is referred to.

Title: Improvements in and connected with electric switches of the tumbler type
IPC: H01H23/18
Filed: 1939-06-14
Abstract: 529,966. Tumbler and rotary switches for A.C. circuits. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., HARRISON, B. G., and MORGAN, R. W. June 14, 1939, Nos. 17348/39 and 9529/40. [Class 38 (v)] In a tumbler or other switch for A.C. currents, the first portion of the movement of the dolly causes the displacement of the "fixed" contact c sideways from the overlapping movable contact l on the dolly thus obtaining a small gap of constant size between the contacts which is maintained till the circuit is broken at the zero of the A.C. cycle ; the last portion of the movement of the dolly causes the bodily moving away of the contact l from the contact c and a progressive lengthening of the gap to secure effective isolation of the contacts. The sideways movement of the fixed contact c is caused by cam action, an insulating portion of the dolly bearing on the contact c to force it downwards. In another form, Fig. 11, in which the movable contact 6 bridges two fixed contacts 7, an insulating projection 9 presses the left contact 7 away from the contact 6 when the dolly carrying the contact 6 is rotated about the axis 15. In another form, Fig. 16, the dolly carries contacts on the side which are gripped between the fixed contacts 21. The two parts of Fig. 16 show the closed and open positions respectively.

Abstract: 1,026,057. Seaming non-metallic sheet material. UNITED-CARR Inc. May 2, 1963 [May 11, 1962], No. 17444/63. Heading B5K. An attaching unit for attachment to a basic heat sealing machine to heat seal a snap fastener member 16 to a workpiece 5 at the same time as the basic machine is performing another heat sealing operation on the workpiece 5, comprises a frame 2 to be attached directly to a portion 1 of the basic machine and a tool device 6 mounted on the frame 2 to hold the member 16 to be heat sealed, the frame 2 and device 6 being provided with relatively movable co-operatable elements whereby the device 6 may move relative to the frame 2 during the fastener applying operation of the attaching unit to feed the members 16 in succession from a source of supply to a position in which they are disposed for heat sealing to a workpiece. The tool device 6 comprises a rotary member mounted on a shaft 7 slidable in slots 8 in the frame 2. A shoe 10 acted on by a compression spring 12 bears upon pins 11 spaced about and secured to the member 6. The shoe 10 is mounted on pins 13 slidable in bores 14 in the frame 2. Peripheral sockets 15 in the rotary member 6 are shaped so as to receive either a plastic snap fastener stud member or a socket member. As shown in Fig. 3, a strip of socket members 16 connected by breakable portions 17 is fed from a reel (not shown) into the sockets 15 as the member 6 intermittently rotates, a tapered finger 18 assisting the movement into the sockets 15. As the member 6 rotates the portions 17 will be stretched and broken but to ensure complete separation a razor blade 19 is provided to enter one of a series of grooves 9 each time the unit is operated. A generally U-shaped latch 22, Fig. 7, is located in the path of the pins 11 and is normally pressed upwardly by a compression spring 23. The latch 22 is also pressed into lateral pin engaging position by a spring-urged finger 25 pivoted to the frame 2. In operation, the frame 1 of the basic m/c. moves downwardly so that the member 6 with a socket member 16 first contacts the workpiece 5 on a bed plate 4 and the frame 2 then moves downwardly relative to the member 6 due to the sliding arrangement of the shaft 7, the shoe 10 and the pins 13. As the member 6 slides upwardly relative to the frame 2 a pin 11 engages over the latch 22 so that as the frame 2 moves upwardly whilst the member 6 is still in contact with the workpiece 5 the latch 22 pushes on the pin 11 and rotates the member 6 one step so that the next member 16 is in position. A sealing bar 31, Figs. 1 and 3, is provided on the frame 1 to simultaneously form a bar seal with the application of the member 16. High frequency current is supplied to the frame 1 and the bed plate 4. The unit may be attached to either the movable head, as shown, or to the stationary bed of the basic machine.

Title: Process for the manufacture of irradiated ergosterol of high antirachitic value
IPC: B68C1/02
Filed: 1931-06-18
Abstract: Antirachitic preparations obtained by the irradiation of ergosterol are purified by causing their inactive components to form double compounds with maleic or citraconic acid anhydrides and separating these compounds by their insolubility in suitable solvents, for example, petroleum ether.  The irradiated ergosterol is dissolved in an organic solvent, for example, benzene or a mixture of ether and petroleum ether, a slight excess of maleic or citraconic acid anhydride is added at normal or slightly elevated temperature, and the mixture allowed to stand until the double compound is formed. The solvent is evaporated, the residue containing the addition compound dissolved in alcoholic potash, the solution heated after adding water, and repeatedly extracted with petroleum ether, or successively with ether and petroleum ether.  The extracts contain the active component, from which the petroleum ether is then removed by evaporation.  The residue may subsequently be dissolved in a vegetable oil, or may be recrystallized from methyl alcohol or acetone.  Oxygen is excluded during the process.  Examples are given.

Title: Improvements in or relating to preselection tuning systems for radio receivers
IPC: H03J5/14
Filed: 1939-06-19
Abstract: 530,835. Electric control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 19, 1939, No. 17856. Convention date, June 18, 1938. [Class 40 (i)] In a motor-controlled tuning system for a wireless receiver, the pre - determined positions to which the tuning member may be driven are adjusted by manually tuning to a desired station and then adjusting a contact member, which determines stoppage of the motor, to a position of correspondence as indicated by a pilot lamp which is normally used as a dial light. The system shown comprises the known arrangement of a motor 18 (windings 10-12) driven under the control of push-button selecting- circuits 40-44 and a commutator 30, 31 until an insulating portion 33 registers with a selected contact 45-49. The motor when energized moves its armature upwardly to engage a star-wheel 20 of a gear train which drives a drum 8 on the condenser spindle and also an indicator 26. Manual tuning by knob 22 also operates on drum 8, the gear train being disconnected from the motor during this operation. The dial lamp 65 is normally directly supplied over secondary winding 66, key 39 being in the position shown during manual or automatic tuning. When it is desired to adjust the system for automatic tuning to a desired station, the receiver is manually tuned and key 39 then thrown to the right to connect lamp 65 in a circuit from ground at 51, over one of the motor supply leads 34, commutator segment 30 or 31, and push-button circuits, to secondary 66. The key 39 is maintained thrown, a selector push-button, say 42, is operated and the corresponding segment engaging contact 47 is adjusted to register with insulating portion 33 whereupon lamp 65 is extinguished. The lamp circuit includes motor windings 10, 11 or not, depending on whether segment 30, 31 is involved so that the difference in the brightness of lamp 65 serves as an indication as to the direction in which adjustment should be made.
