Abstract: 347,507. Mercury switches for electric signs. GENERAL KONTROLAR CO., Inc., 200, East First Street, Dayton, Ohio, U.S.A.-(Assignees of Bossard, G. L. ; 200, East First Street, Dayton, Ohio, U.S.A.) May 22, 1930, No. 15739. Convention date, May 31, 1929. [Class 38 (v).] Two mercury tube switches 21, 27, each having three electrodes, are mounted by means of clips 33 on rocking arms 31, 32 which are pivoted at 48. A shaft 39 carries two cams 37, 38, which engage the forked ends 35, 36 of the arms 31, 32. The cams are set 90‹ apart so that on rotation of the shaft 39 the mercury switches are oscillated to connect the central electrodes to the outer ones in succession. The shaft 39 is driven through gear wheels 76, 77 by an electric motor 64, 66 of the induction disc type, giving about 200 oscillations a minute. The invention is described as applied to an electric sign having a border of lamps which are successively illuminated to give the impression of moving bands of light. The lamps are divided into four circuits by connecting together every fifth lamp. Each circuit is connected to one outer electrode of one of the mercury tubes and the mains supply is connected to the central electrodes. When the mercury switches are oscillated by means of the cams 37, 38 the four circuits are successively energized to give the appearance of a number of moving bands of light. To minimize flexure of the leads from the mercury tubes, they are attached to the spindles on which the rocking arms 31, 32 are pivoted, and are then brought down to a set of terminals on an insulating block 89, carried by a pillar 91 on the back-plate 50 on which the apparatus is mounted. The mechanism is fixed in its containing box by a forked lug 104 engaging a grooved stud 105, and by two pillars 102 which are screwed into ears 100 carried by the back of the box.

Title: Transparent electrically conducting films
IPC: H01B1/00
Filed: 1950-06-26
Abstract: <PICT:0682342/III/1> <PICT:0682342/III/2> In a method of treating a vitreous surface to produce a transparent electrically conducting film thereon which treatment includes exposing said surface while at its softening temperature to the action of a tin halide in fluid form and during which treatment hyrochloric acid gas is formed, the step of preventing said gas from reacting with the hot surface before said film is formed thereon so as to prevent the formation of fog in the film. The film is preferably formed by spraying the tin halide in liquid form on to the surface.  The gas may be removed mechanically, e.g. by means of an air spray, before it contacts the surface, or the entire surface may be blanketed with filming spray, or the reaction of the spray solution from the gas may be retarded either by using a cold spray solution and/or cold atomizing air.

Title: Method of determining lipase activity using a triglyceride reagent and method for preparing that reagent
IPC: C12Q1/44
Filed: 1977-04-15
Abstract: The reagent for the determination of lipase activity in a solution consists of a solid matrix of an inert carrier which is soluble in an aqueous reaction solution and is impregnated with a triglyceride. The carrier is preferably impregnated with triolein; the carrier is, for example, a sugar. To prepare the reagent, at least one triglyceride is dissolved in a solvent. The resulting solution is then mixed with an appropriate amount of the inert carrier which is soluble in an aqueous reaction solution. Finally, the solvent is evaporated off so that a solid matrix of the carrier impregnated with the triglyceride remains. The lipase activity in a sample is determined by reacting the sample with an emulsion of a triglyceride in an aqueous reaction solution and measuring the rate at which the triglyceride is hydrolysed to soluble fragments.

Title: Improvements in or relating to couplings for coaxial electric cables
IPC: H01R9/05
Filed: 1943-09-28
Abstract: 570,339. Two - part couplings. BRITISH INSULATED CABLES, Ltd., CARSTEN, H. R. F., and THORPE, C. H. M. Sept. 28, 1943, No. 15907. [Class 38 (i)] Coaxial conductors are coupled together by screwing both the outer and inner couplings simultaneously, the threads on the outer coupling being of slightly different pitch from those of the inner coupling so that the threads lock. A tubular enlargement 1 attached to the outer conductor 2 has an external thread 11 or complementary internal thread 12 and a similarly enlarged rod 6 screwed to the inner conductor 7 is similarly screw threaded at 13, 14. The inner and outer coupling members are spaced apart by blocks 5 split so as to be placed round reduced square necks 15 and clamped in the members 1. by screw rings 10 so that relative movement of the members 1, 6 is prevented. The threads 11, 12 differ in pitch from the threads 13, 14 and the pitch of the outer threads is preferably greater so that the tension on the joint is taken by the outer conductor. Where long cables cannot be relatively rotated they may be joined by a connecting piece, Fig. 4, comprising an outer tube 21 and an inner rod 26 each having right and left handed screw threads at opposite ends to enable the connecting piece to be screwed to both cable end couplings simultaneously. The pitch of the outer and inner threads differs by the same amount at both ends so that the two pairs of threads will lock at the same time. If one locks before the other the small angular movement necessary to complete the locking is obtained by twisting one of the cables.

Abstract: 382,581. Sound-reproducing devices. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Blattner, D. G.; 112, Laurel Road, Mountain Lakes, New Jersey, U.S.A.) June 6, 1932, No. 15984. Convention date, Aug. 12, 1931. [Class 40 (iv).] Relates to pneumatic sound-reproducing devices in which a fluid stream is modulated by an electromagnetically vibrated diaphragm, the field magnet being mounted in a casing to form therewith a fluid passageway. According to the invention, the casing has a fluid-inlet opening in its lower portion and a downwardly projecting part on its upper portion, forming with the diaphragm an outlet from the fluid passageway. In the loud-speaker unit shown, the magnet system comprising a cup-shaped member 5 and a central polepiece 6-is mounted within a casing 17 of such dimensions that an annular space 18 is formed between the walls of the parts 5, 17. The diaphragm 11, carrying the vibratory coil 10, is clamped to the annular polepiece 9 by a ring 12. A cover 23 is screwed to the casing 17, with its inner edge disposed as shown so as to form between it and the diaphragm a restricted annular outlet 25 from the passage 18. The inner walls of the passage adjacent to the outlet 25 are streamlined, and spacers 19 which separate the magnet 5 from the casing 17 are also of streamline form. Fluid such as compressed air is admitted through an opening 21 to the passage 18, the vibrations of the diaphragm varying the dimensions of the outlet 25, and thereby modulating the fluid stream. In order to balance the static pressure of the fluid on the front of the diaphragm, the air stream is-divided so that part of it acts on the rear of the diaphragm. For this purpose, a ring of holes (not shown) is formed in the diaphragm, and the polepiece 9 is provided with a number of radial ducts 26, the inner ends of which are close to the diaphragm, behind the orifice 25, the ducts being connected to tubes 28. These extend through the casing 17, and are provided with valves 29.

Title: Process for treating artificial fibres
Inventor: FURNESS VERA ISABELLA
IPC: D01F6/18
Filed: 1960-05-06
Abstract: Fibres or filaments of polyacrylonitrile, or of copolymers containing at least 80% of acrylonitrile, are rendered more resistant to heat and steam discolouration by treating the "neverdried" material with aqueous solutions or suspensions of reducing agents.  The process may be carried out by passing a bundle of the wet fibres through a bath containing a 0,1%-10% solution of the reducing agent, optionally at elevated temperature.  The treatment may be combined with other treatments such as finishing.  Suitable reducing agents are thiourea dioxide, sodium or potassium metabisulphite, formaldehyde, and compounds yielding formaldehyde.  The latter group includes paraformaldehyde, sodium formaldehyde bisulphite, and methylol derivatives of amides, for example hydroxymethyl formamide and hydroxymethyl dimethyl hydantoin.  Examples, using a copolymer of acrylonitrile, methyl acrylate and itaconic acid, compare "fibre yellowness" when treated and untreated samples are heated in air or in steam under pressure.

Filed: 1973-04-04
Abstract: 1401380 Lasers UNITED AIRCRAFT CORP 4 April 1973 [26 April 1972] 16129/73 Heading H1C The carrier frequency and mode-locked pulse repetition rate of a laser Q-switched by a saturable absorption cell are regulated by the use of a dispersive resonator resonant to a limited range of frequencies only and by control of the resonator length. A CO 2  laser is shown in Fig. 2, in which the active medium cell 34 is located with a gas saturable absorber 36, in a resonator formed by mirrors 30, 32, the resonator being made frequency restrictive by a series of dispersion prisms 38. The mode-locked laser output is monitored by a photo-detector 52 the output of which is compared with a reference frequency from a source 50 in a synchronous demodulator 48. After amplification at 46 the demodulator output is applied to a hollow cylindrical piezo-electric crystal 40 to control the resonator length. In a modification, Fig. 3 (not shown), the photo-detector output is applied to a discriminator the D.C. output of which is compared with a reference potential. In an alternative embodiment, Fig. 4, the resonator 30, 32 is made frequency restrictive by incorporating in the gas absorber 36a an additional gas, such as chloro-trifluoro-ethylene, which is highly absorptive at frequencies other than that at which the saturable gas, e.g. sulphur haxafluoride, has a saturable absorption characteristic. In the arrangement shown the length of the resonator, and therefore the carrier frequency and pulse repetition frequency, is directly controlled by a voltage applied to the piezo-electric crystal 40. Helium-neon or other gas mixtures which may be in continuous flow may be used as the active medium. The limited range of resonator frequency control may be used to sweep the carrier frequency according to a continuous or step function.
