Title: Gas springs
IPC: F16F9/02
Filed: 1963-04-04
Abstract: 1,017,555. Pneumatic dashpots. STABILUS, INDUSTRIE - UND HANDELSGESELLSCHAFT m.b.H. April 4, 1963 [July 19, 1962], No. 13442/63. Heading F2S. A gas spring comprises a piston 6 and cylinder 4, the piston being provided with valve means which allows a flow of gas in both directions of movement of the piston. The cross-sectional area of the flow paths in each direction are different. The volume of gas in the cylinder with the piston rod fully retracted from the cylinder is not greater than twice the volume of the gas when the piston-rod is fully telescoped. The arithmetic mean of the gas pressures in the two positions of the piston-rod is greater than 70 atmospheres absolute. In the construction shown, the piston 6 is provided with apertures 7 which communicate with a peripheral, annular groove 9 and a bleed passage 10. A piston ring 8 is seated in the groove such that when the piston is moved in the direction B the rings abut the lower side of the groove as shown in the Figure and gas is permitted to flow only through the bleed passage 10. With the piston moving in the opposite direction the ring 8 abuts the upper side of the groove such that gas flows also through the gap 11 surrounding the piston and apertures 7. Alternatively, the piston may be provided with apertures having flap valves for controlling the flow of gas.

Abstract: 1,010,371. Protective systems. GENERAL ELECTRIC CO. Ltd. April 8, 1963 [April 9, 1962], No. 13589/62. Heading H2K. In a protective system for a rectifier circuit arrangement having bridge rectifiers 1, 2 arranged in at least two parallel circuits, detector transductors 6, 7 detect any undue disparity between the operation of the parallel circuits. In Fig. 1, the D.C. conductors 4, 5 and 8, 9 from the rectifiers form opposing control windings of the transductors 6, 7, which have A.C. windings 9, 10 connected through rectifiers 14, 15 to opposing control windings 16, 17 of a common output transductor 18. The coil 20 of an indicator relay is connected in series with the A.C. winding 19 of the transductor 18. In an alternative system, Fig. 2 (not shown) the detector transductors may have their control windings connected in the A.C. conductors to the rectifiers. In this case the A.C. windings of the detector transductors supply a common control winding on the output transductor which may have an A.C. bias winding. The relay may be hydraulically damped so that under severe fault conditions other protective equipment may operate first.

Filed: 1971-05-07
Abstract: 1333870 Pyroelectric radiation detectors WESTERN ELECTRIC CO Inc 7 May 1971 [7 May 1970] 13754/71 Heading H1K A pyroelectric detector capable of detecting the modulation of incident I.R. radiation modulated at a frequency of at least 1 MHz comprises a crystalline body having an acoustic loss of not greater than 5f dB. per second, where f is a resonant frequency of the freely suspended body, mounted in such a manner as to increase its acoustic loss to at least 6f dB. per second. The provision of acoustic damping increases the frequency response of the detector by suppressing one or more vibrational modes of the crystal. As shown, Fig. 1, a plate 1 of LiTaO 3  is secured to a glass slide 2 by means of a layer 3 of a conductive epoxy which provides the required acoustic damping and forms one electrode, and is provided with a small electrode 4 of transparent or absorbing material on its free face. The detector may be arranged in a housing which may serve merely as a mechanical support or may form a resonator for the incident radiation. The radiation (I.R.) is focused on to the detector by a Ge lens, Fig. 2 (not shown). The detector responds to Q-switched laser pulses having a length of 20 nS. and has a rise time of less than 5 nS. In a second embodiment, Fig. 3 (not shown), a plate of pyroelectric material is provided on opposite faces with orthogonally arranged strip electrodes and then encapsulated in a transparent medium such as polyethylene to provide the required damping. The pyroelectric material may be LiTaO 3 , triglycene sulphate or triglycene selenate and the damping material may comprise various epoxies, polyurethane, rubber, polymethylmethacrylate or polyethylene.

Title: Improvements in and relating to the spinning of artificial silk
IPC: D01F2/04
Filed: 1935-05-11
Abstract: A cuprammonium solution is spun in a funnel through nozzles having a diameter of less than 0.6 mm. into water to which has been added such small quantities of organic or inorganic acids of greater acidity than carbonic acid that the filaments leave the funnel neutral or alkaline whilst the precipitating liquid leaves the funnel still having an acid reaction.  Suitable acids are formic, acetic, oxalic, tartaric, citric, and sulphuric acids and organic sulphonic acids, and these may be employed in concentrations of, for example, 4, 8, or 10 grams per litre.  In an example, a normal cuprammonium solution such as is described in Specification 423,642 is spun through a nozzle of diameter 0.3 mm. into water containing 5 grams per litre of sulphuric acid at a temperature of 25 to 35 DEG  C.  The water leaving the funnel is still acid whilst the filament reacts neutral or weakly alkaline.

Title: Improvements in or relating to electric discharge devices

IPC: H01J17/48
Filed: 1953-05-19
Abstract: 740,838. Multi-gap cold-cathode tubes. STANDARD TELEPHONES & CABLES, Ltd. May 19, 1953, No. 14015/53. Class 39 (1). A cold-cathode glow discharge tube of the glow transfer type comprises a cathode of the general configuration of a headed wire nail, and a slender wire tail associated therewith and projecting in the line of glow transfer. The cathodes, Fig. 1, each comprise a shank 5 on the end of which is formed a head portion 6 in the form of a disc, and a spacing disc 7 preferably integral with the head portion 6. The shank 5 is passed through a hole in an insulator 3 so that the disc 7 spaces the head 6 above the surface of the insulator by a distance equal to the length of the cathode dark space for a glow discharge just covering the head of the cathode. The cathode is secured to the insulator 3 by a metal clamping tube 10 surrounding and welded at 11 to the shank 5. The clamping tube 10 also surrounds and is welded at 15 to a lead 14. The anode 4 is mounted on a lead 141 by means of an eyelet 16 and collar 17. A fine wire cathode tail 9 is secured underneath and bent to lie substantially in the plane of the head portion 6 of the cathode 1 so as to project to within a distance equal to the length of the cathode dark space from the periphery of cathode 2. A method of assembly is to secure several cathodes in position on the insulator 3, each cathode having secured thereto a rather longer length of fine wire than is required to form a cathode tail. A spacing jig is then positioned beneath the heads of two adjacent cathodes and the cathode tail bent to the required shape against the jig before being cut to the correct length. Alternatively the cathode tail may comprise a straight length of wire welded directly to the periphery of the head 6, a length of wire welded to the clamping tube 10 and passing through an extension of the aperture in the insulator through which the cathode shank 5 is passed, or through a separate aperture and then bent to lie in the same plane as the cathode head 6, or a wire loop having a straight portion lying in the same plane as the head 6 and two ends which are passed through apertures in the insulator 3 and welded to the clamping tube 10. In a completed tube, Fig. 3, the leads 14 are sealed through the glass base 13 of the envelope 12 and support the cathode assembly in position beneath the anode 4 which is supported on four leads 14<SP>1</SP>. A curve is given showing the variation of cathode current with anode-cathode voltage, for a cathode of specified dimensions. Specification 692,415 is referred to.

Abstract: 1389682 Refractories MINNESOTA MINING & MFG CO 24 March 1972 [25 March 1971] 14016/72 Heading C1J A refractory comprises a porous alumina structure, a phase of chromia filling at least the bores adjacent the outer surfaces and a solid solution of alumina, having been formed upon heating to a temperature below that of sintering in at least part of the chromia. It is obtained by impregnating the structure with a chromium containing solution, heating at 500-1000‹ C. to form chromia, then at 1000‹-1600‹ C. but below sintering to form the solid solution. Impregnation and the lower temperature heating can be repeated, e.g. 15 times.
