Title: Method and apparatus for lining hot-tops
IPC: B22D7/10
Filed: 1966-12-05
Abstract: 1,120,314. Lining moulds. FOSECO TRADING A.G. 5 Dec., 1966 [6 Dec., 1965], No. 54299/66. Heading B3F. In a method of making and fitting heat insulating liners 15 in hot top casings in which cleaned and prepared casings 11 are successively presented to a lining station, a perforated hollow former 26 is located into each casing to provide an annular cavity between the inside of the casing and the outside of the former, and a slurry constituted by finely divided refractory material, a fibrous material and a liquid carrier is fed into the cavity. The liquid carrier is drawn off through the perforated former so as to build up a layer of fibrous and refractory material on the former which is dislodged from the former to be retained on the inner surface of the casing to form the liner. The former is subsequently removed from within the casing and the completed casing is transferred to a drying station to dry the lining prior to its use with an ingot mould. The casings arrive at the lining station on a roller conveyer a portion of which is in the form of a lifting table 21 which raises the casing by hydraulic means 28, 29 to position the former 26 within the casing 11 and to clamp and seal the top and bottom of the casing prior to the introduction of the slurry through the manifold 30. The removal of the liquid carrier which is usually water, is effected by differential pressure and this may be achieved by the actual pressure of the slurry as fed to the lining cavity which forces the liquid through the porous former, evacuating the casing cavity so as to draw off the liquid or by preheating the casing 11 to a temperature above the boiling point of the carrier causing vaporization thereof when in contact with the walls and resulting in a pressure increase in the lining cavity to force the liquid through the former. The liquid withdrawn flows into a chamber 43 in the lifting table 21 and is carried to waste through pipe 44. To release the liner from the former a short burst of compressed air is admitted to the interior of the former which is then separated from the easing by lowering the casing to the conveyer level. Alternatively the former may be of the collapsible type in order to be freed from the lining. The internal surface of the casing has a suitable configuration 51, 52 to key the liner to the casing. In an alternative embodiment the liner may be formed on the former prior to its insertion into the hot top casing. The fibrous constituent of the slurry may be organic, such as paper pulp or inorganic, such as asbestos fibres, or a mixture of both together with a refractory such as silica flour or other known refractory materials. Exothermic materials may also be included in the slurry.

Abstract: 1291606 Electro-medical apparatus HUMETRICS CORP 6 Nov 1969 [6 Nov 1968] 54423/69 Heading G1N A variably recurrent waveform signal, as particularly described an ECG signal, is monitored and analyzed by means of a gating circuit 25 and analysis circuits 52, Figs. 2, 3 and 4 (not shown), the amplified ECG waveform signal (A) and also signals (E), (F), (M) and (W), Fig. 5, derived from the ECG waveform signal as shown, being utilized so that the gating network 25 supplies twelve signals (a), (b) (c), (o), (p), (n), (P), (P), (Q), (V), (X) and (X) to the analysis circuits to energize the appropriate circuits for analyzing corresponding portions of the ECG signal as they arrive. A reference phase position in each ECG waveform complex is detected at 14 and 16 when the first derivative of the signal goes more negative than a negative reference level -Vr, as indicated by signal C, operation of the subsequent circuitry being controlled by this signal so that the gating network identifies each incoming wave portion of the ECG signal (A) and provides the appropriate one of the twelve signals. In the analysis circuits 52, the various wave portions, i.e. the P, Q, R and S waves, are analyzed with reference to predetermined standards and indicate whether the various waves are too wide, too high or too low, or whether the R and S wave durations are too long or the P-R interval is too long or too short. Fig. 6 (not shown), provides means for disabling the analysis indicators in response to the 60 Hz background signal. This circuit may also disable the indicators for excessive arrythmia and excessively high or low heart rates.

Filed: 1968-11-19
Abstract: 1,245,979. Hydraulic reciprocating motors. TEXAS INSTRUMENTS Inc. Nov.19, 1968 [Dec. 20, 1967], No.54789/68. Heading F1A. [Also in Divisions G3 and H4] The radiating member of a seismic wave generator is reciprocated by the controlled flow action of a fluid whose viscosity is varied by application of a field. A generator for use on land comprises, Fig.1, radiating member 12 which is held against the ground by the weight of a transport truck acting on sprung plate 16. A hydraulic motor for reciprocating member 12 consists of reaction mass 20, cylinder 22, drive rod 18 and four electrostatic valves 30, 32, 34, 36 each comprising a set of concentric cylindrical electrodes. The valves rely on the Winslow effect in certain fluids: when a valve is energized by a voltage from amplifier 42 the field within the valve increases the hydraulic fluid viscosity, thus blocking fluid-flow. The fluid is pumped, under pressure, through cylinder 22 via inlet 24 and outlets 26, 28. Valves 32, 34 are fixed to rod 18, and valves 30, 36 are fixed to cylinder 22, so that by energizing first the valve pair 32, 36 and then the valve pair 30, 34, the rod 18 is reciprocated. A control signal drives amplifier 42, whereby the generator output follows the control signal. The control signal may be programmed by radio command and may be adjusted, to compensate for different earth characteristics, by a feedback loop including an accelerometer 52 and position transducer 54 coupled to rod 18. The hydraulic fluid pressure and temperature are monitored at 76 and 74. In a generator for marine use, Fig.3, the hydraulic motor comprises Winslow-effect valves 136,138 fixed to piston rods 108, 110 and similar valves 140, 142 mounted outside cylinder 102. Piston 106 and rods 108, 110 are reciprocated by energizing valve pair 138, 140 alternately with valve pair 136, 142, thereby varying the volume of a chamber defined by diaphragm 134, plate 128 and flexible annular seal 132. In a modified marine seismic generator, Fig.4, (not shown), valves 136 and 138 are replaced by a second pair of valves mounted outside the cylinder. The various generator embodiments provide little phase shift between the seismic output and the control signal, so that several generators may be used in parallel.

Abstract: 1,166,087. Television; cathode-ray tube displays. FERNSEH G.m.b.H. 14 Dec., 1966 [22 Dec., 1965], No. 56006/66. Headings H4F and H4T. Two signals having different characteristics are displayed separately on the screen of an indicator each display being associated with a scale appropriate to the signal involved and which is selected by switch means also operable to change from one display to the other in accordance with a control signal derived from the characteristics of the two signals. In the described embodiment the two signals comprise monochrome television and colour television type signals selectively supplied to terminal 11, Fig. 1, the indicator comprises a cathode-ray tube 1 and the scales comprise appropriately engraved members 13, 14 selectively edge illuminated in different colours by lamps 8, 9. When monochrome signals are supplied to terminal 11 horizontal or vertical synchronizing signals are supplied to terminal 12 and with switch 7 in the position shown by heavy lines the monochrome signals are fed via amplifier 2 to the Y deflection plates to modulate a time base trace produced by a sawtooth generator 4 and supplied to the X plates via amplifier 3. In this mode of operation switch contact 7<SP>111</SP> energizes lamp 8 so that the trace on the tube screen is viewed in association with the illuminated scale 13 which is calibrated in terms of signal amplitude (see Fig. 2). When the signal supplied to terminal 11 is replaced by a colour signal a vector demodulator 5 derives the R-Y and the B-Y colour difference signals and also, by means of "colour killer" circuitry, supplies a signal via switch 16 in the position shown by the heavy line. which operates a relay 6 to change over the contacts of switch 7 so that the R-Y and B-Y signals are supplied to the tube deflection plates via the respective amplifiers 2 and 3, lamp 8 extinguished and lamp 9 energized. The resultant vector display is then viewed in association with the illuminated scale 14 (see Fig. 2). The automatic change over also prevents damage to the tube screen if, e.g. the monochrome signal were displayed as a vector trace. By operation of switch 16 so that switch 7 reverts to the position shown in heavy lines the colour signal may be displayed as a transmission level trace. In practice the lamps 8, 9 which are fitted in mounts 8<SP>1</SP>, 9<SP>1</SP> (Fig. 2) carried by a green filter 15 project through apertures 13<SP>1</SP> and 141 in the scales 13, 14 a red ring filter 13<SP>11</SP> and a yellow ring filter 14<SP>11</SP> surrounding the respective lamps, and to prevent each lamp from illuminating the other scale a reflective coating is provided in the aperture not appropriate to its scale through which it projects when the three elements 15, 13, 14 are assembled.

Title: Bubble logic circuits

Filed: 1973-12-07
Abstract: 1454408 Magnetic storage arrangements MONSANTO CO 7 Dec 1973 56768/73 Heading H3B Certain of the 3 input-3 output magnetic bubble logic arrangements described in Specification 1,434,280, are combined to provide a reset-set flip-flop or a trigger flip-flop. In the Figures the symbols 1 and a diagonally-crossed rectangle respectively denote a bubble stream source, and a bubble annihilator as described in the prior Specification. Similarly the circle, triangle and rectangle notations denote particular bubble reactions within the logic arrangements. Reset-set flip-flop.-In Fig. 1 a bubble stream passes through logic arrangements 12, 10 in turn, and after a one bit delay in a storage loop again passes through arrangement 10 to an output Q. If a reset bubble is applied to arrangement 12 over a reset path R a bubble in the stream is diverted to an annihilator. Normally a bubble presence in both the outgoing and return paths in logic arrangement 10 maintains repulsive equilibrium, but when a bubble is absent from the return path consequent on a reset interruption the following bubbles in the stream transfer to the annihilating centre path and the output terminates. Setting back to the original state is obtained by a bubble in set path S which, by repulsion, prevents the stream from continuing to divert to the annihilating path. The bubbles now passed to the output Q through the return path maintain the set state by repulsive action. Trigger flip-flop.-A trigger bubble is applied to a logic arrangement 13, Fig. 2, through a path T. This bubble transfers to a centre path and commences to circulate in a closed loop comprising a storage loop and an upper path. While this condition exists the circulating bubble deflects a bubble stream applied to a further logic arrangement 15 to an output Q. This deflected output terminates when a further trigger bubble is applied to path T, since this bubble, by repulsion, prevents the normal transference of a circulated bubble from the upper to the centre path.
