Abstract: 233,582. Morichard, J. H. A. Sept. 8, 1924. Charts and diagrams.-An apparatus for graphically indicating information or positions comprises a plate, plan, or the like provided with graduation marks over which a number of parallel endless wires, each consisting of two easily-distinguishable parts, is movably mounted. The plate 1, Fig. 1, provided with horizontal graduations, is formed with notches at the upper and lower edges in which grooved discs 3 are mounted. Endless wires 5, consisting of two parts of different colour or thickness, are placed round the discs, one set of which, preferably the lower, is provided with milled edges. On a square shaft 7 adjacent to the row of milled discs is a slide 8, Fig. 2, to which is pivoted an arm 9 carrying a milled disc 12 of a width equal to that of the grooved discs. The discs 12 may be pressed, against the action of a spring 10 acting on the arm 9, into engagement with any of the grooved discs so that they may be rotated to bring the connection 6 of the two colours or thicknesses of the wire into position to indicate any information desired. A movable horizontal ruler may be arranged on the plate. Specification 101,061 is referred to.

Abstract: 713,912. Drying grain. HALLMAN, N. J. Aug. 27, 1952, No. 21568/52. Class 34(2) In the drying of grain which is preheated, passed through a sweating zone 4 and then through a drying zone 6 where it is permeated by warm air, the material in the sweating zone 4 is permeated by air which has passed through the drying zone and is at a temperature lower than that of the grain so that its surface temperature is reduced and moisture in the grain diffuses to the 'surface whilst the material in the following drying zone is permeated by air of a higher temperature to raise the grain surface temperature and evaporate the moisture. The grain passes downwardly through a column 1 having a preheating zone 2, and sweating zone 4, and after leaving the drying zone 6 enters. a cooling zone 8 where it meets atmospheric air drawn in by a fan 10. This air leaves the. zone by a duct 13 and duct 14, passes through a fan 15 and heater 16 to duct 17 and then to the preheating zone via duct 19 from where it is recirculated. Air also passes to the drying zone 6 via duct 18 and then, having been cooled, via duct 21 to the sweating zone 4 whence the moist air is discharged to the atmosphere via duct 22. Cooled, dried grain is discharged via vaned wheel 9. The column 1 is divided into the zones by constricted portions 3, 5, 7.

Title: Improvements in or relating to inverter circuits
IPC: H02M7/515
Filed: 1965-05-24
Abstract: 1,034,322. Inverting. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 24, 1965 [July 6, 1964], No. 21810/65. Heading H2F. A series inverter comprising a main pair of silicon controlled rectifiers 15, 16 connected across a centre-tapped supply 11, 12, 13, includes commutating circuitry comprising a commutating capacitor 25 and a pair of commutating silicon-controlled rectifiers 22, 26 each associated with a series inductor 23, 27. The operation is such that each main rectifier is switched on and then off again before the other main rectifier conducts, and the arrangement provides that the " dv/dt problem " does not arise in respect of the commutating rectifiers 22, 28, i.e. it ensures that these do not provide an inadvertent short-circuit across the supply. In operation a pulse is applied to rectifier 28 and shortly after rectifier 15 is pulsed, when current flows in the resonant circuit 25, 27 and at the same time load current starts to flow to the left. At this instant the voltage across the inductor 27 is E (E = 2 v.), and current in this circuit flows until this voltage is reversed when the rectifier 28 prevents reversal of current. At this stage the capacitor is charged to 2E (i.e. 4 v.) with the left-hand plate positive. When subsequently rectifier 22 is pulsed the capacitor discharges through the reverse diode 29 shutting off the rectifier 15. Soon after the rectifier 21 is fired when load current starts in the opposite senses, and capacitor 25 is charged to 2E with the r.h. plate positive. Subsequent firing of rectifier 26 shuts off rectifier 16 and the cycle is repeated. The voltage across the capacitor may be limited to just more than E instead of 2E by the provision of diodes connecting the supply terminals to the junctions of the inductorcommutating capacitor combinations (Fig. 3, not shown). If this voltage limitation is provided for the first half-cycle after switching on, it is thereafter effective, and by ensuring that one of the two main rectifiers is always to be the one to fire first on switching on, only one of the two diodes need be provided. Alternatively a single diode shunting the inductors 53, 57 may be provided. The voltage limiting diode may be taken out of circuit after the first half cycle by a relay operating in dependence on a single shot circuit energized by the first load current pulse.

Patent GB-615106-A (GB)
Title: Improvements relating to radio-frequency inductances and tuners
IPC: H03H7/01
Filed: 1946-07-24
Abstract: 615,106. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 24,1946, No. 22017. Convention date, July 24, 1945. [Class 38 (ii)] [Also in Group XXXVII] . A radio-frequency inductor is so wound that there is little mutual inductance between adjacent turns. Such an inductor may comprise figure-of-eight and loop turns wound alternately upon two supporting pegs, or alternate half figure-of-eight turns and half loop turns as shown in Fig. 1 (part). Not only does the small mutual inductance between turns make the final adjustment by moving the turns less critical, but the absence of a substantial external field allows the mounting of inductances in close proximity without mutual interference as shown in Figs. 3 and 4. Inductors according to the invention are wound on pins P mounted on insulating disc 9. Each inductor is connected in series to a similar inductor mounted coaxially on the opposite side of the disc 9, the free ends being connected respectively to contacts 15 on insulating wafer 11, and similar contacts on wafer 23, which contacts are engaged by arms 13, 25 mounted on a rotatable shaft 27. The junction of each pair of inductors is connected to one end of an associated inductor wound on teeth t on disc 9, the other end of which inductor is earthed. By rotation of the shaft 27 the appropriate set of three inductors is connected in the signal input circuit of a very high frequency superheterodyne first detector stage of a television receiver. At the same time a third moving contact 43 on the shaft 27 engages a fixed contact on a third insulating wafer 31 to connect in the local oscillator circuit the appropriate one of solenoidal inductors 33, 35, 37, 39, 41, each of which has a screwed brass core such as 47 for initial calibration. Each core may be coated with an insulating plastic, and is engaged by a spring 57 to prevent core movement after adjustment.
