Title: Improvements in and relating to thermal insulation
IPC: F16L59/04
Filed: 1953-04-02
Abstract: 730,114. Heat insulation. GENERAL ELECTRIC CO. April 2, 1953 [April 4, 1952], No. 9153/53. Class 64 (2). An evacuated insulating body such as a panel has spaced surfaces 10, 11 enclosing a blanket 14 of mineral fibres, e.g. glass, and a blanket 13 of fibres, e.g., silica or aluminium oxide, of higher melting point mineral, each of the fibres being randomly oriented but with its axis parallel to the plane of the portion of the surfaces nearest the fibre, particularly as set forth in Specification 715,174. The surfaces may be of quartz, or may be sheets of stainless steel, "Monel" metal (Registered Trade Mark) or carbon steel and the edges 12 of the body may be sealed by welding. The surface 10 may be a carbon steel sheet protected by ceramic enamel and form the cooler side of the panel while the surface 11 adjacent the silica and exposed to heat may be stainless steel. The body may be shaped to conform to an apparatus. The fibres of the blanket 13 may be of nearly pure silica prepared by heating a blanket of alkali borosilicate glass fibres then leaching out the alkali and boron constituents with hydrochloric acid and heating further. The glass fibres are first compacted as described in Specification 715,175 but batts may be made by substituting glass fibres for cellulose fibres in a paper making machine to give a specific gravity of 0.25.

In a modification the chains are parallel to each other and travel in the same direction at different speeds. The fastest conveyer is only partly filled directly by the disc and the gaps in it are filled from the slow conveyers by pushers.

Abstract: 964,487. Matrix stores. SPERRY RAND CORPORATION. March 11, 1963 [March 21, 1962], No. 9535/63. Heading G4C. In an addressing arrangement for a matrix core memory (not shown), a memory address register MAR receives an address word comprising three binary coded decimal digits, each decimal digit being coded in 5-4-2-1 form. An arrangement of AND and OR gates 1, 2 &c. is connected to the outputs of the stages of the register MAR, the arrangement being such that for each address word stores in the register MAR, a series of three different address-selecting outputs is obtained on leads EU 1 -EH 5 , the second and third outputs being produced by means of respective auxiliary pulses A, B, applied as shown to the gating arrangement. The matrix core memory is thus addressed three times although only one address word is stored in the address register MAR.

Title: Web coating apparatus
IPC: B05C11/10
Filed: 1972-03-02
Abstract: 1378597 Coating control EASTMAN KODAK CO 2 March 1972 [4 March 1971] 9712/72 Heading G1A [Also in Division D1] In the coating of a moving paper web with photographic emulsion, to avoid coating the plastics leader, the degree of transparency of the material to infrared radiation is sensed by a photoelectric measuring arrangement and the coating applying means controlled accordingly. Paper from supply roll 10 has spliced thereto a leader 18 which may be up to 700 feet long. After passage through pre-conditioning area 12, the web passes through the photo-electric arrangement 20, for detecting the presence of a splice, a device 70 for developing clock pulses and the coating station 22, to drying area 24 and take up 26. The light emissive diode 38 is caused to produce a series of pulses of infrared radiation by means of an astable multi-vibrator 32 and Darlington pair 36. When the plastics leader is in the radiation path, little radiation is absorbed and high amplitude pulses B, Fig. 3 are produced by photo-transistor 40, which detects the transmitted radiation. At each such pulse, normally charged capacitor 46 discharges and immediately starts to recharge, resulting in a sawtooth waveform C, Fig. 3 being applied to transistor 48. At voltages above C', transistor 48 is caused to conduct, gating on transistor 50 which produces pulses of a certain width E, Fig. 3. Circuit 54, 56 is set so that these are adjusted in width so as to be just insufficient to actuate relay 58. Potentiometer 52 is to cancel the effects of ambient light received by the detector. When a plastics to paper splice passes the detection station, the paper allows only a small amount of radiation to reach the detector and small output pulses are produced F, Fig. 3. This results in capacitor 46 hardly discharging G, Fig. 3 and long duration pulses I, Fig. 3 being applied by 50 to the relay 58 which is actuated. A time delay relay 64 is provided after relay switch 58a so that if a plastics to plastics splice has been detected (which would result in a return to high amplitude detected radiation) the actuation signal from relay 58 is not passed on to AND gate 68. The latter receives the output of the relay circuit and clock pulses from 70 so as to start the coating apparatus when the splice reaches the hopper 63.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 31, 1940.] [Class 38 (iv)] [Also in Groups XII and XIX] Fluid pressure. In boiler control system in which the water supply is automatically regulated in accordance with consumption the back pressure of the steam on the water supply is maintained constant by regulating fuel and air supplies alike by means controlled by steam pressure variations, the fuel supply comprising a main supply sufficient either for conditions of least efficiency or of greatest efficiency, this supply varying with the water supply, and a further portion respectively subtracted from or added to the main supply and controlled according to steam pressure variations. As shown in Fig. 1 a water motor T33 drives an alternator Ad electrically connected to a synchronous motor M13 driving the fuel pump B3. A byepass valve V33 subtracts a varying proportion of this fuel, its setting being adjusted in accordance with steam pressure variation by a reversible motor M23 controlled by a compressed air manometer and relays R13, R23. With solid fuel the motor M23 would adjust an inclined blade on the conveyer for the main fuel feed. In the alternative arrangement complementary feed would be provided, as by a centrifugal pump the discharge valve of which would be controlled similarly, but reversely, to valve V33. In a modification the motor M23 may regulate rheostats governing the complementary supply. The movements of the valve V33 may be graphically recorded to afford an indication of boiler efficiency when compared with the feed water records. The air control arrangements are shown in Fig. 2 where the motor M23 is coupled by gearing to a rotary shutter W controlling an auxiliary air supply and a centrifugal device driven by the fuel pump actuates a main damper M39. Further adjustment of fuel supply is afforded by a contoured valve Va actuated by elliptical gearing driven from a centrifugal device on the water motor A39 to provide for conditions of greatest inefficiency in working ; a supplementary air valve R39 is similarly operated. The manometer comprises a tube J3 filled with water, an inverted U-tube k3 containing oil in its upper part and an indicating tube L3 of reduced diameter filled with a conducting liquid such as salt water connected at its upper end to an air receiver O. The level of the conducting liquid co-operates with electrodes a<SP>3</SP>, b<SP>3</SP> in the control of the relays and with electrodes C<SP>3</SP>, d<SP>3</SP> in the operation of high and low pressure alarm indicators. The actuating coils and relays are energized by induction from primary windings P1, P3 when the manometer contacts are made.
