Title: Improvements in or relating to electrical sleeve coupling and terminal connectors
IPC: H01R13/28
Filed: 1944-07-12
Abstract: 600,711. Cable and wire couptings. STEVENS, A. H. (Thomas & Betts Co.). July 12, 1944, No. 13321. [Class 38 (i)] In an electrical, connector of the type shown, the terminals 16, each having a segmental contact tongue 23, are inserted in a resilient sleeve 11, not necessarily metal, rolled from a blank, and having a longitudinal slit 12, to distend a pair of arcuate spring arms 14 formed by the transverse slots 13, and thus maintain a pressure on the tongues ensuring a good contact between the plane surfaces 24. Each terminal has an oval bead 21 to engage a transverse slot and a concentric latching neck into which a pair of detent spring arms 15 on the sleeve snap to lock the terminal. The tongues 23 are so made that preferably two form, in cross-section, an oval joint assembly and provide two diametrically opposite clearance areas C in the sleeve to afford the free flexure of the spring arms 14. The supply leads are secured to the terminals in cuffs 18, e.g. by crimping. In a modification (Fig. 14, not shown), a metallic sleeve forms a single plug-in connector, e.g. for earthing, and is shaped to fit the tongue closely and so provide an efficient conducting path. The Specification sets out the optimum relationship between the dimensions of the sleeves and the terminal parts.

Title: Cyclic polysiloxanes derived from dichlorosilane and dimethyldichlorosilane
IPC: C07F7/08
Filed: 1956-05-01
Abstract: The invention comprises cyclic polysiloxanes having the formula [(H2SiO)m(Me2SiO)n] where m and n are integers of from 1 to 5 and their sum is from 4 to 6.  They are prepared by hydrolysing in aqueous ether solution a mixture containing dimethyldichlorosilane and dichlorosilane in a mol. ratio of from 1 : 10 to 10 : 1 at a temperature below 25 DEG  C., preferably at 0 DEG  C., when the predominant product is tetramer and pentamer with a minor amount of hexamer.  In an example, a fraction is identified as [(Me2SiO)3-(H2SiO)] and [(Me2SiO)2(H2SiO)3].  The tetramer is equilibrated with hexamethyl disiloxane in the presence of conc. H2SO4 at room temperature to produce a linear polysiloxane oil useful as a water-repellant for paper and textiles.

IPC: F02M7/24
Abstract: 133,298. Cozette, R. J. P. E. Sept. 28, 1918, [Convention date]. Spray carburettors.-The carburettor comprises a float chamber 1 supplying, through a restricted orifice 2, a well 3 which may be open to the atmosphere through an aperture 5 and delivers fuel to the air passage of the carburettor at a point where the suction is a maximum. The well has projecting into it a tube 6, the lower end of which is either open or perforated, the upper end being provided with a valve 7 by means of which the depression in the well can be regulated at will to vary the richness of the mixture at normal and high speeds. In a modification, the tube projects into a supplementary well between the well 3 and the restricted orifice 2 and forming with the well 3 a U tube. The flow of air through the tube 6 into the well may be utilized to check the flow of fuel from the orifice 2. Air from the aperture 5 serves to vaporize fuel drawn from the well, but the aperture may be omitted.

Abstract: 143,559. Trinks, F. May 20, 1919, [Convention date]. Multiplying and dividing apparatus, of the pinwheel and cam-disk type having two digits in complementary double rows upon each numeral drum of the totalizing-counter, is arranged so that it can be used as two separate totalizers by providing it with an inspection slide a having apertures showing one set of figures only and divided with two parts a', a', which can be moved independently, or which can be coupled by a pin c entering a slot b<2> and used together. As an example of the calculations possible by this construction, assume 4 per cent of interest has to be deducted from 800 marks. The number 1 is set up in the eighth digit place of the adjusting-mechanism, so that, on subtraction, a series of nines appears in the slide holes 8 - - 13. By displacing the part a<1> of the slide, the zeros are rendered visible. After cancelling the period 1, the gross amount 800 is set up in the digit places 3, 2, 1, and one hundred times this amount is transferred to the places 5, 4, 3, 2, 1 after displacing the carriage by two denominational places. After zeroizing the re volutions-counting mechanism U and pushing the carriage to its initial position, the gross amount is also set up in the digit places 10, 9, 8 and the operating-handle given four turns in the direction of subtraction. The revolution-counting mechanism shows the percentage deduction, the adjusting-mechanism the gross amount, and the totalizer shows the amount deducted in the places 11, 10, 9, 8, and the net amount in the places 5, 4, 3, 2, 1. If the totalizer is in two parts having separate zeroizing-mechanism and corresponding with the sections of the slide, it is possible to show the sum of various amounts deducted at the same percentage.

Filed: 1916-10-03
Abstract: 125,644. McLennan, D. Oct. 3, 1916. Telephones.-In apparatus for detecting subterranean sounds, a diaphragm carrying a microphone forms one wall, preferably the underside, of a chamber containing liquid such as a mixture of glycerine and distilled water, in contact with the diaphragm. The diaphragm chamber may be mounted so that its inclination may be adjusted to vary the vibration frequency, and is preferably contained in a casing supported directly or indirectly by the ground. The casing is preferably hermetically sealed and adapted to act as a resonator. A microphone i in circuit with a telephone receiver, not shown, is carried by a diaphragm c mounted on a dished plate d to form a liquid containing chamber h. The whole is mounted in a cylindrical casing a pivotally connected to a support n, or resting directly in contact with the ground. Moisture absorbing material such as calcium chloride is placed in the casing and is held in place by a perforated retainer m. Sealing material a' such as wax may be introduced. The plate d may have annular grooves in the surface facing the diaphragm to improve the efficiency of the device. The inclination of the diaphragm is varied by tilting the casing in the support n. Alternatives are described in which the diaphragm chamber is mounted at a fixed inclination in the casing or provision is made to vary the inclination within the casing as by means of rods operated from without. Two or more diaphragms c, c<1>, c', Fig. 9, of different diameters with intermediate liquid chambers may be used, the microphone being carried by the outer diaphragm c. Two or more microphones may be provided connected in parallel or series, and the diaphragm may form part of the circuit. Specification 125,645 is referred to.
