IPC: B29C43/02
Filed: 1963-09-16
Abstract: 1,071,335. Making gramophone records. DECCA Ltd. Aug. 26, 1964 [Sept. 16, 1963], No. 36328/63. Heading B5A. In a method of making a gramophone record, a pre-formed blank, i.e. a blank requiring only a sound track to be embossed thereon to complete manufacture, is fed to an embossing press as described in Specification 1,071,333 and is centred with respect to the dies thereof by means of a pin 28 which passes through the spindle hole of the blank. The pin 28 is integral with a double acting air operated piston 26 and is moved by admission of air to a cylinder 32, 35 formed in a bushing 27 fixed centrally of one die assembly. In operation, a disc is held in approximate position between the dies, the tapered end 31 of the pin 28 is urged through the spindle hole to centre the disc, and on continued movement, the pin enters a second bushing 23 fixed centrally of the other die assembly and causes, by feed of air through a bleed passage 29, operation of a switch 43 and hence closure of the dies. The pin 28 is automatically retracted before the dies are opened. Since movement of the dies occurs subsequent to the operation of switch 43, no action occurs if pin 28 fails to pass through the spindle hole of a disc.

Abstract: 161,136. Guthrie, W. S. Dec. 30, 1919. Spray carburettors.-In carburettors having a main and an auxiliary nozzle in separate chambers the auxiliary chamber receiving its air from the main chamber intake, the auxiliary nozzle is of relatively large bore near its base. The main nozzle 10 and the auxiliary nozzle 30 are located respectively in a main mixing-chamber 3 and an auxiliary mixing chamber 31 which discharges into the main mixing-chamber near the edge of a throttle valve 4 through a valve-controlled or a calibrated orifice 33. Air to the auxiliary chamber 31 is taken from the main passage and enters through a port 32 of cross-sectional area less than that around the nozzle 30 in order to prevent noise. A valve 5 controls the air inlet 2, from the nozzle side of which supplementary air passes through conduits 40, 41 to dilute the mixture as described in Specification 160,927. The nozzles are fed from a passage 9 which communicates with the float chamber 6 through a valve-controlled or a calibrated orifice 36. The orifice may pass slightly more fuel than is necessary, and the valve when seated may not entirely cut off the flow. At low speeds, mixture, is sup. plied from the passage 31 but, as the throttle is opened and the speed increases, air enters the nozzle 30 and passing downwardly mixes with the fuel on its way to the main nozzle, 10, whilst at the same time the passages 40, 41 come into action. The auxiliary nozzle being in its lower part of large bore serves as a reservoir to augment the supply of fuel to the main nozzle during acceleration.

Title: Electronic stores
IPC: G11C16/16
Filed: 1975-09-09
Abstract: 1517926 FET storage matrix SIEMENS AG 9 Sept 1975 [20 Sept 1974 12 Feb 1975] 36980/75 Heading H1K [Also in Division G4] In an electronic store consisting of a matrix of storage cells, each consisting solely of an N- channel storage FET with a floating gate and a superposed control gate both of which control the main current path of the FET and so constructed as to permit programming by negative charging the floating gate by channel injection, at least some of the corresponding terminals, e.g. sources, drains or channel of at least some of the cells are connected together. In the embodiment, Fig. 2, the control gates of all cells in a row are connected to the respective X-conductor, the drains of all cells in a column to the respective Y-conductor, and the sources of all cells in the matrix to a common point S o , which may be earthed by connection to S U , placed at voltage U by connection to R U , or left floating. The cells may be formed on a common semiconductor substrate which may be earthed or left floating and may also include the control circuitry S t  though the store and control circuitry may alternatively be in separate epitaxial semiconductor layers on a common substrate of spinel or sapphire. The construction enables voltages to be applied to programme the cell individually by storing electrons on their floating gates and to read the state of individual cells. Stored information may be erased from individual cells, or from all cells in a row or the matrix simultaneously. Such simultaneous erasure can be achieved with minimal heat generation if the FETs are of the enhancement type, by using the Fowler- Nordheim tunnelling or, if the floating gates are of P-doped polycrystalline silicon more than 1000 Š thick, by the gate surface effect mechanism. The tunnelling mechanism requires application of a direct voltage or series of pulses between control gate and source, drain or channel region with the others of these regions floating, while the gate surface effect requires a train of pulses with steep leading flanks, e.g. with a frequency of 100 KHz to 1 MHz and a keying ratio of 1 : 1. In either case voltage pulses are applied with the control gate held at a fixed potential, such as earth. The thickness of insulation between the floating gate and substrate is so chosen e.g. at 600 Š to avoid partial discharge of a cell by drain avalanching when its drain is connected in common with that of another cell being programmed, and to prevent avalanche effect at a reverse-biased PN junction in the main current path of the FET making a major contribution to erasure of the cell. Lower operating voltages can be used if the capacity between the control and floating gates greatly exceeds that between the floating gate and substrate, and contamination of the gate insulation of the gate insulation, reduced by so operating that the programming and erasure currents pass through spaced portions of it.

Patent GB-1108589-A (GB)
Title: Improvements in the production of cement
IPC: C04B7/60
Filed: 1965-08-31
Abstract: Cement of low alkali content is produced from limestone-containing raw meal by calcining at least some of the meal below 900 DEG  C. in a first firing stage 5, sintering the calcined meal above 1300 DEG C. in a second firing stage 7, cooling at least some of the alkali-containing gases 16 from the second firing stage by heat exchange with raw meal 4 to condense alkali metal salts from the waste gas but avoiding appreciable condensation on the raw meal, and removing condensed salts as an alkali-containing dust 18.  Heat exchange of the alkali-containing waste gas with raw meal at 4 may be effected in three ways offering varying degrees of avoidance of an alkali cycle: (i) the gas and meal undergo direct heat exchange predominantly by radiation in countercurrent flow through a simple rotary tube (ii) the gas is drawn through a bed of uniformly granulated meal on a travelling grate (iii) the gas and meal are passed countercurrently through a tubular system in indirect heat exchange.  Part of the raw meal may be pre-heated by the alkali-free waste gas of the first firing stage and part by the alkali-containing gas of the second stage, both parts then being fed to the first firing stage, or the second part being passed directly to the second firing stage.  In the wet process (Fig. 2) the slurry may be dried by the alkali-free gas, and optionally some of the alkali-containing gas, and then preheated by all, or some, of the alkali-containing gas.  Alkali volatilization in the sintering stage may be promoted by CaCl2. The combustion air used in this stage may be heated by exchange with the hot clinker after charging with steam by contact with the raw meal granules.
Patent GB-375301-A (GB)
Abstract: 375,301. Colour photography and kinematography. NORDMANN, C., Observatory de Paris, Avenue de l'Observatoire, Paris. Feb. 17, 1931, No. 5041. Convention date, Feb. 17, 1930. [Class 98 (ii).] In the reproduction by contact printing of origina lenticular colour - record images on lenticular sensi tive material, moirÚ effects are avoided by employing a fixed source of printing light, and causing the moire pattern to move across the film during printing by interposing between the lightsource and the films a transparent light-deflecting element which is displaced relatively and parallel to the films during exposure in a direction perpendicular to the lenticles of the films. In the case of intermittent-feed printing- apparatus, a condenser Q or a third transparent lenticular film T may be displaced parallel and near to the films O, C in the path of the printing light during the printing period. In the case of continuous-feed printing-apparatus, a third transparent lenticular film T which remains stationary in the printing-gate may be used. When a lenticular film is used, its lenticles are disposed parallel to those of the films which are being printed. The speed of the relative movement between the transparent element and the films is such that the displacement of the moire pattern during the exposure is equal to the pitch of the moire pattern. Reference is made to various methods of avoiding moirÚ effects in printing by optical projection, including the interposition of a transparent lenticular film in the projection beam.
