Filed: 1961-11-29
Abstract: A process of producing a porous insulatory product comprises mixing an expanded synthetic polymeric thermoplastics and/or thermosetting material with an inorganic binder having a melting-point above the temperature of vaporization of the thermoplastics and thermosetting material and with an inorganic filler, moulding the mixture to shape, heating the shaped mixture to cause vaporization of the polymer and cooling the mixture to form a porous product.  A powdered filler of particle size between 0.06 and 0.2 mm., e.g. quartz, slag sand or fireclay and a gas-permeable filler, e.g. kieselguhr, asbestos, rice-straw ashes, vermiculite, diatomaceous earth may be used. Expanded or unexpanded thermoplastic material in thread or tubular form may also be present.  Suitable inorganic binders (which are used in combination with water), are cement, fireproof cement, plaster of Paris, water glass, sulphite lye, or magnesite together with magnesium or sodium sulphate or sulphuric acid.  Specified thermoplastic materials are polystyrene, polyvinyl chloride and polymethyl methacrylate.  They may have a particle size of 0.1 mm. to 3.0 mm.  The grain size and packing of the components may be chosen to give a wall thickness of binder of 5 to 200 microns between the pores in the product.  The expanded thermoplastic or thermosetting material is preferably strengthened by storage for 8 to 14 days before it is mixed with the other ingredients.  In an example, mouldings are prepared from a mixture of hydrocarbon-expanded polystyrene particles, finely-ground sand and fireproof cement and the moulded articles are dried at 60 DEG  to 70 DEG  C. and heated at 300 DEG  C. to vaporize the polystyrene.ALSO:A process of producing a porous insulatory product comprises mixing an expanded synthetic polymeric thermoplastic and/or thermosetting material with an inorganic binder having a melting point above the temperature of vaporization of the thermosetting and thermoplastics material and with an inorganic filler, moulding the mixture to shape, heating the shaped mixture to cause vaporization of the polymer and cooling the mixture to form a porous product.

Title: Circuit arrangements for analysing read-out signals from magnetic film stores
IPC: H03K5/1536
Filed: 1972-09-18
Abstract: 1387738 Magnetic data stores SIEMENS AG 18 Sept 1972 [17 Sept 1971] 43104/72 Heading G4C [Also in Division H3]  A circuit arrangement for recognizing zero transits in signals supplied by magnetic film stores includes an output energized only when the differentiated read out signal exceeds a fixed threshold for a predetermined period of time, the arrangement including a capacitor charged via a first resistor and discharged via a second resistor when the differentiated read out signal exceeds and does not exceed respectively the fixed threshold and a second threshold circuit to determine when the charge on the capacitor exceeds a threshold corresponding to the fixed threshold maintained for the predetermined time. As described signals read from a magnetic store are differentiated so that zero crossings are transformed into peaks. The differentiated signals are fed to a zero crossing detector ND, e.g. a conventional threshold circuit and to a timer circuit SPS. The timer circuit includes a conventional threshold circuit AB feeding a circuit ZB which produces an output only if the output of AB presents for a predetermined period. Zero crossings in the original signals are only indicated, e.g. by flip-flop FF which is primed by the signal from SPS and triggered by the signal from ND, in the presence of an output which remains above the threshold for a predetermined period and spurious zero crossings due to small period parasitic signals are thus eliminated. The timing circuit, Fig. 2, comprises a transistor T1 which, when no signal is applied from the threshold circuit AB, conducts to discharge capacitor C with a time constant determined by R1. When a threshold output occurs T1 is blocked and C charges with a time constant determined by R2. The voltage to which C charges is limited by diode D to prevent excessive potentials being developed. The potential at point 3 is detected by a differential amplifier T2, T3 whose other input is fed by a voltage divider R5, R6. If the threshold output of AB persists for a period sufficient to allow capacitor C to charge to a potential at which the differential amplifier changes state an output signal AZ is developed. The charge/discharge periods of capacitor C in conjunction with resistors R1, R2 are chosen so as to eliminate high frequency, spurious signals present in the input to the device. In particular the use of discharge resistor R1 prevents the capacitor discharging instantaneously, e.g. due to a short lived reduction in signal level, and genuine read out pulses being lost due to the completely discharged capacitor never triggering the differential amplifier.

Abstract: 1,074,449. Velocity-modulated tubes; electrode materials. SFD LABORATORIES Inc. Oct. 12, 1965 [Oct 26, 1964], No. 43279/65. Heading H1D. A toroidal, helix-derived, slow wave structure is constructed by forming a toroidal tube, of rectangular cross-section, by welding endplates 2 to the two ends of a pair of coaxial, coterminous cylinders 3 and 4, radially slotting the tube through its inner and two end walls, and finally forming a corresponding series of axial slots 7 in the outer wall, inclined at an angle such as to interconnect adjacent radial slots, the portion 6 being left unslotted to define the ends of the structure. A modified form in which the outer and the end walls are curved is also referred to. The structure, which may be of molydenum, copper, aluminium, or stainless steel, may be employed in an M-type device (Figs. 6 and 7, not shown), wherein it is mounted between electrically insulating, thermally conductive annuli 23 of boron nitride or beryllium oxide within a copper envelope 21, 22. The coaxially mounted, secondary emissive cathode 26-of beryllium/copper or aluminiumis in the form of a hollow cylinder enclosing a magnet 29 having polepieces 28 which also act as cathode end hats and produce an axial magnetic field in the interaction space 27. The cathode-magnet assembly is supported by an axial cathode lead 32, with respect to which the envelope and slow wave structure are maintained at a high D.C. potential. The tube may be employed as a forward wave amplifier, when the slow wave circuit is provided with input and output coaxial lines, e.g. 25; alternatively, it may be used as a noise generator, in which case the tube is filled with hydrogen, argon, or xenon at 10<SP>-1</SP> torr, and the input coaxial line is either dispensed with or, if present, terminated in a matched resistive load. A separate thermionic emitter may be employed as electron source, instead of the secondary emissive electrode 26.

Abstract: 1,026,680. Winches; transhipping at sea- G. L. SHILLINGER. Oct. 28, 1964 [Dec. 16, 1963], No. 43899/64. Headings B8B and B8E. In apparatus for transferring loads at sea, by a suspended trolley 11 moving between spaced stations 1, 2, Fig. 1, a pair of reels 4, 6 is arranged at one station 1 for winding opposite ends of a single transfer line 3 looped over a sheave 8 at the other station 2. Both reels 4, 6 are driven in opposite directions to effect the transfer while tension sensing means controls a separate drive to the reels for tension compensation purposes. The load is supported by a pulley running on the upper line and attached to the lower line. Winch drive.-The hydraulic drive system, Fig. 4 (not shown), for the separate winch motors 21, 22 comprises separate electric motors 26, 29 for the transfer and tension control each driving a pair of variable volume reversible flow pumps 27, 28 and 31, 32 controlled from hydraulic actuators 102, 142. When the load approaches either end of its travel, valve gear 47 is automatically actuated by microswitch and cams (see below) to control the tension from one or other of the reels 4, 6 only, so that the adjustments occur in the longer part of the line 3 to prevent the load from being accidentally moved against the ship. End stop gear comprises micro-switch and cam combinations 87-89, Fig. 5 (not shown), associated with the winch drive shafts 66, 81 and operating as the load approaches either end of its travel. They control the actuation of solenoid valves 113, 114 (Fig. 9, not shown), in the hydraulic control system whereby the pump displacement actuator 35 is moved to decelerate the drive until reaching its neutral position. The stop gear is also associated with a reversing gear. Similar micro-switch and cam combinations 74, 76 control valve 4 (Fig. 4, not shown) to transfer the tension control to a single winch as the load approaches the end stations. Tension regulation, Fig. 10 (not shown), illustrates a system in which the line tension is sensed by spring-loaded plungers 131, 132 in the hydraulic drive lines 133, 134 to the winch motors 21, 22. Movement of the plungers controls the output from hydraulic pumps 31, 32 via actuator cylinder 142. Micro-switches 163, 164, 169, 175 associated with a solenoidoperated valve 171 operate to restore the actuator cylinder 142 to its neutral position on restoration of the required tension.
