Title: Method of or means for reducing the voltage drop in rectifiers
IPC: H02M7/06
Filed: 1927-04-21
Abstract: 277,929. Meyer, F., and Spanner, H. J. Sept. 24, 1926, [Convention date]. Vapour and low-pressure apparatus, arrangements of.- The voltage drop in rectifiers, normally equal to a mean value between the striking voltage at which the arc starts in each half-wave and the lower cut-off voltage at which the arc fails, is reduced by superposing an auxiliary high-frequency voltage on the main voltage to be rectified so that the striking voltage is reached or exceeded at the electrodes at or shortly after the moment when the main voltage passes through a value equal to the cut-off voltage. The arc thus strikes earlier in each halfwave and when the arc strikes the auxiliary voltage falls to a negligible value for the rest of the half-wave. The voltage drop is thus reduced to the cut-off voltage, for example, to 5-10 volts. Rectifiers of the mercury-vapour or incandescentcathode, gas-filled types and insulating tubes around the cold electrodes to prevent reverse discharges and discharges between the cold electrodes are referred to. The rectifier preferably utilizes the shielding effect of electrodes at a distance apart equal to the mean free electrode path as described in Specifications 274,026 and 275,550, [both in Class 39 (i), Electric lamps, Arc &c.]. In rectifying low-frequency current from a transformer T<1> by a double anode, incandescent cathode device U feeding a direct current circuit 0, a high-frequency source of high impedance relative to the resistance of the arc in the device U is coupled to a transformer T<2> and is effectively short-circuited by the arc when this strikes. Shunting condensers C<1>, C<2> are arranged as shown. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an auxiliary direct voltage superposed on high-frequency voltages to be rectified. This subject-matter does not appear in the Specification as accepted.

Abstract: 129,103. Mossay, P. A. H., and Mossay & Co. July 2, 1918. Interlocking and guarding against wrong movements and the like. - The speed-controller of an electrically-propelled railway-platform truck is held in the ' off ' position by a spring and the brake is held on by a spring; a common operating pedal releases the brake before actuating the controller. A coiled spring 5 tends to hold the brake lever 4 in position with the band brake 6 on, and the lever 4 is connected by a link 3 to the pedal lever 2. A chain 7 attached to the lever 2 passes round a wheel 9 on the spindle of the speed controller and is attached to a spring 12. When the pedal is depressed the brake is released, and after a period of lost motion the controller spindle 10 is rotated. When the pedal is released the springs 12, 5 return the controller to the ' off ' position and apply the brake. The main switch is operated by a removable lever which can occupy any one of the positions ahead, reverse, or stop and has a projection which allows the lever to be put on or off only when the spindle is in the ' stop ' position. The main, switch and the speed controller are interlocked so that the controller cannot be operated nor the brake removed when the lever is in the stop position. An aperture for the admission of a plug for charging the accumulators is closed by a shutter 17 which is locked in position by one of the arms 18 when the main switch is in the ahead or reverse position.

Title: Roller bearings
IPC: F16C25/06
Filed: 1948-04-21
Abstract: 642,356. Roller bearings. HERBERT, Ltd., A., and LLOYD, A. H. April 21, 1948, No. 10963. [Class 12 (i)] To take up radial slackness and to pre-load a roller bearing the outer race ring is of conical formation engaged by a bush having a bore of complementary taper and supported in a cylindrical bore of a stationary housing, means being provided to effect relative axial movement between the ring and bush. As shown, the rotating spindle 11 of a machine tool is supported in the stationary portion 20 of a headstock by a bearing comprising an inner race ring 12 fast on the spindle 11, double-row caged rollers 14a, and an outer race ring 13 whose conical periphery 16 coacts with a complementary bore 17 of a bush 18 secured in the headstock. In assembly, a ring of screws 30 in a clamp-plate 29 are tightened thereby forcing the outer race ring 13 to the left, relative to the bush, thereby progressively radially compressing the bearing. To dis-assemble, the screws 30 are slackened and bolts 27 are tightened, which causes a back-plate 26 to force the outer race ring 13 to the right. A split adjusting ring 32 of selected thickness predetermines the amount of preloading. The rollers 14a are located in grooves in either race-way, the complementary race-way being plain. In a simpler construction, a single-row roller bearing is described in which the dismantling means are omitted, the outer race being axially stationary and the bush axially movable.

Abstract: 1,235,235. Treating food; treating seeds with gases. D. F. FARKAS and M. E. LAZAR. 28 Feb., 1969 [7 March, 1968], No. 11008/69. Headings A2D and A2Q. [Also in Division F4] Particulate material is treated with a gas by introducing it into perforated basket 5, rotating the basket to apply centrifugal force to the material, and directing a stream of gas via inlet 2 through the mass of material in a direction counter to the centrifugal force, the velocity of the gas stream being sufficiently high to cause the individual particles actively to tumble about within the mass, but not so high as to eject particles from the mass before they have undergone a predetermined treatment. The velocity of the gas stream may be sufficiently high to fluidize the mass of material. The process is applicable to drying and dehydrating foods, e.g. peas, beans, other vegetables, fruit, meat, yeast, bones, feathers, wool or cotton, puffing wheat, rice, corn, potatoes and fruit, roasting coffee, cooking or blanching foods, cooling and freezing foods, and reacting solids with gases. Smoke or sulphur dioxide may be added to the chamber. In a continuous process, e.g. drying, the material is introduced at a desired rate by compressed air through inlet 15 and is only ejected into chamber 17 when its density has been sufficiently reduced by drying.

Title: Storage control apparatus for a multiprogrammed data processing system
Inventor: BAHRS DAVID LEROY
IPC: G06F3/06
Filed: 1969-02-28
Abstract: 1,263,743. Data storage. GENERAL ELECTRIC CO. 28 Feb., 1969 [6 March, 1968], No. 11024/69. Heading G4C. In a storage control system, read and write operations for sectors of a circulating storage member (e.g. disc-set or drum) are controlled by control words, one per sector, obtained from a store (e.g. core) as the respective sectors become accessible, the system also responding to control words which do not represent a storage operation. A processor and an extended memory controller communicate with the core store (which is the main memory of the system) via a memory controller. The disc-set communicates with the extended memory controller. Core-disc data transfer (e.g. of programme segments in a multiprogramming system) is under the control of a string of DCWS i.e. data control words (double-length words) each specifying a disc address (sector and track-set), a core starting address, a function code specifying e.g. direction of transfer or no operation, and the address of the next DCW. If there are N sectors, the member of DCWS may be any integral multiple of N, being accessed cyclically and passed to the extended memory controller under the latter's control as the respective sectors become accessible. When a DCW has been used to control core-disc transfer, its function code is changed in core store to the no operation code. A supervisor programme updates such DCWS in core according to new transfers required, utilizing a continually updated pointer address held in core specifying the address of the DCW relating to the currently-accessible sector. Core-to-disc transfer is serially by 36-bit word, parallel by bit, from core to four 36-bit holding registers in the extended memory controller. When all these are full their contents are transferred in parallel to sixteen 9-bit shift registers which are subsequently (after equality in a sector-address comparison) shifted out to respective disc tracks. 64 words are thus transferred, ending when a sector-end signal comes from the disc store. Disc-to-core transfer is the reverse, using the same registers.
