[Also in Divisions B5 and D2] A heat-insulating refractory product comprises a first layer of fibrous material, granular refractory material and a synthetic-resin binder, and a second layer of a bonded or unbonded mass of fibrous refractory material or a felted organic material, the fibre content of the second layer being 30-80% by weight. The product may be a slab or sleeve for lining hot-tops and risers when casting metals, the first layer being on the side in contact with the metal. The first layer may be thinner and denser than the second. The fibrous material of the first layer may be organic or refractory or a mixture of the two. The refractory filler of the first layer may be silica flour, zircon or olivine flour, magnesia or a refractory silicate, and the binder phenolformaldehyde or urea-formaldehyde. The second layer may contain both organic and inorganic fibres, binder and refractory filler. Either layer or both may contain a sintering agent, e.g. sodium silicofluoride or sodium nitrate. The two layers may be formed by successive deposition from aqueous slurries on a former, or by forming the two layers separately and then sticking them together. In examples, the fibre of the first layer is : (1) amosite asbestos and paper pulp; (2) asbestos; (3)" Kaowool" (Trade Mark); (4) paper; (5 and 6) slag wool and paper; (7 and 8) calcium aluminium silicate fibres and paper; in each case the binder is phenol-formaldehyde and the granular refractory silica flour. In further examples: (9-14) the second layer comprises calcium silicate fibres, paper, phenol-formaldehyde and silica flour and is used with the first layer of Example 1 or 4; (15-17) the second layer is similar but has a sodium silicate binder (instead of phenol-formaldehyde) and is used with the first layer of Example 1; (18-20) the second layer is similar to those of Examples 9-14 but has amosite instead of calcium silicate fibres and is used with the first layer of Example 1, 2 or 3.

Filed: 1969-12-18
Abstract: 1280698 Writing telegraph VICTOR COMPTOMETER CORP 18 Dec 1969 [20 Feb 1969] 61853/69 Heading G1N A writing telegraph comprises a transmitting section 10 which produces A. C. voltages at two frequencies representative of X, Y co-ordinates of a stylus 15, which voltages are to be stored in a magnetic tape recorder 12 for subsequent reproduction by a stylus 58 in a receiver section 13, and a compensator section 11 which reduces the frequency errors introduced into the co-ordinate signals by the tape recorder. The error introduced by the recorder is a fixed time deviation for a given tape speed. Thus as the frequencies of the signals to be recorded are reduced, the frequency deviations in the recorded signals due to recorder error are proportionately reduced. The compensator beats X co-ordinate signals having a mid-band frequency of 2200 Hz and Y co-ordinate signals having a mid-band frequency of 1400 Hz with a local oscillator frequency of 1620 Hz and produces lower difference frequencies centred on 580 Hz and 220 Hz respectively, which lower difference frequencies are recorded. A corresponding upconversion is effected upon reproduction of the signals.

Patent GB-698320-A (GB)
Abstract: 698,320. Bridge circuits. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. July 7, 1952 [July 26, 1951], No. 17073/52. Class 37. An A.C. bridge permitting the measurement of impedances varying within wide limits as to modulus and phase angle has in one arm a variable condenser connected to a star type network comprising three resistances connected to a common point, one of these being fixed and the other two variable and ganged together. The impedance X to be measured forms one arm AB, Fig. 1, of the bridge, the second arm BC comprising a fixed calibrated resistance Q. The arm CD includes a calibrated variable condenser K1 which may be connected in parallel, through a switch S1, with a calibrated fixed condenser K and also, through a switch S2 with a further fixed resistance R1. An A.C. generator G is connected across the diagonal AC and a telephone receiver T across the diagonal BD. A star network comprising three resistances has two of its outer terminals L, M connected to opposite sides of the condenser K1 and its third terminal N connected to the corner B of the bridge. The network comprises a fixed calibrated resistance Ro and two calibrated variable resistances with values (Ro-2r) and r connected between the common point and the terminals L, M, N. Fig. 4 shows the construction of the star network L, M, N. The branch connected to terminal L comprises a fixed resistance Ro. The branch connected to terminal M comprises a fixed resistance having a value (Ro-2R) in series with two variable and identical resistances capable of continuous variation through sliding contacts and of the same value (R-r). These two resistances are constituted by two identical potentiometers PI, P2 mechanically coupled. The resistance branch connected to the terminal N comprises the resistance r variable from zero to R and forms a portion of the potentiometer P1. In the branch DA of the bridge there may be inserted either a resistance P, if the phase angle of the impedance X is positive, or a capacitance K2 if this phase angle is negative.

Title: Digital exposure control system for a camera
IPC: G03B7/16
Filed: 1978-12-09
Abstract: The system has a first counter (CT1 Fig. 13 not shown) for storage of a digital shutter-time signal and a second counter (CT2) for producing pulses for sequence control. When self-timer operation is required, pulses from the last bit of the second counter (CT2) are gated into the clock pulse input (CP) of the first counter (CT1) so that the two counters are in effect arranged in series to allow a relatively long self-timer period to be determined. Once timed, the two counters revert to their normal operation for exposure control. The control system may operate in a diaphragm-priority automatic exposure mode, in which case an analog photometric measurement is made and converted to a digital shutter time value in the first counter (CT1). If a flash gun is used, the flash duration is controlled photoelectrically. However if the storage capacitor is not fully charged, a daylight exposure is automatically selected upon shutter release, a check current is fed to an electromagnet for 8 ms to test battery potential. If too low (or if the film is not wound on) release is prevented.

Provision is also made for the peak time enhanced tariff to be used. A timer may be provided to de-activate the controlled equipment and re-set the coin mechanism at intervals independent of the time of setting of the coin mechanism. <IMAGE>
