Abstract: 1,048,230. Locking device for two-part couplings. THORN ELECTRICAL INDUSTRIES Ltd. May 31, 1965 [July 9, 1964], No. 28398/64. Heading H2E. As two parts 10 and 27 of an electrical connector are slidably mated, heads 24 of latches 26, pivoted on a sleeve 13 carried by the part 10, override steps 32 provided on the part 27 and thus lock the parts together (Fig. 4, not shown). During the last part of the movement of the sleeve 13, it moves forward relative to the body 11 of the part 10 and compresses a spring 16 which forces the parts into sealing engagement with each other. The. catch is released by moving an outer sleeve 17, backwards against the action of a spring 18 so that an abutment 21 forces down the tail 25 of the latch, and thus lifts the head. The expansion of the spring 16 assists in the initial movement of the part 27 away from the parts 13 and 17 of the connector 10. Correct mating of the two parts is ensured by grooves 31 carried by the part 10 engaging appropriate recesses in the part 27.

Title: Method and devices for constructing concrete piles moulded in the ground
IPC: E02D5/38
Filed: 1939-10-30
Abstract: 533,338. Piles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. Oct. 30, 1939, No. 28986. Convention date, Nov. 18, 1938. [Class 68 (ii)] In constructing concrete piles in the ground by the aid of a preparatory tube or tubes the concrete is introduced through an inner auxiliary tube 5 which is rapidly vibrated longitudinally with the object of annulling friction with the concrete and rendering the weight of the concrete fully available for consolidating the pile. The concrete may be loaded also by a monkey placed upon it or by compressed air. Vibration is maintained while the auxiliary tube is withdrawn. The tube 5 may be of sheet metal and has a limited lateral play in the preparatory tube 1. Electric motors 6, 7 driving unbalanced weights, or pneumatic monkeys, may be mounted on the upper end of the auxiliary tube and to prevent the vibration produced thereby being transmitted to the tube 1 a cork, rubber or other resilient washer may be interposed. The lower end of the auxiliary tube may have flaps formed by longitudinal saw cuts or trapezoidal segments secured to it to assist the progressive spreading of the concrete as the two tubes are removed together. Reinforcing members 4 may be inserted before the tube is filled.

Title: Treatment of trees
Inventor: NEWCOMER JACK SAMUEL
Filed: 1964-07-14
Abstract: Vascular tree disease (e.g. dutch elm disease or oak wilt) is combatted by applying to the tree a sub-lethal amount of 2,3,6-trichlorophenylacetic acid or of mixtures thereof with other isomeric trichlorophenylacetic acids (e.g. the 2,4,5-isomer with or without the 2,3,4-isomer).  The 2,3,6-acid or its mixture may be employed in the free acid form, dissolved or dispersed in a carrier such as water or an organic solvent, or in a carrier which is at least in part a solid (e.g. clay or vermiculite), also, the 2,3,6-acid or its mixture may be employed in the form of water-soluble salts, such as the sodium, potassium or organic amine salts, and such salts may be used dry or in water solution. Other hydrolysable derivatives such as acid halides, anhydrides, esters and amides, which are hydrolysed to the corresponding acids after application to the tree, can also be used. Application may be by spraying the leaves, painting or spraying the tree limbs and trunk, injection into the tree, implantation as a solid in the trunk and limbs and/or distribution on or in the ground at the base of the tree.  A growth-inhibiting amount may be used.

Title: Improvements relating to surgical drapes
Inventor: GUTHRIE JAMES LEVERETTE
IPC: A61L15/28
Filed: 1965-07-08
Abstract: Sheet material suitable for use as a surgical drape is made by beating a suspension of cellulosic fibres, mercerizing the suspension with an aqueous alkali, separating the mercerized pulp from the mercerizing solution, swelling the fibres with hot water or dilute aqueous acid, washing, beating, forming the pulp into a web and impregnating the web with an elastomeric material.  The alkali may be sodium hydroxide, and the acid oxalic, sulphuric, hydrochloric, nitric or acetic.  The pulp may be separated from the mercerizing solution by centrifuging or filtration or on a paper machine.  The pulp may be of softwood, cotton, hemp, regenerated cellulose or bamboo.  The elastomer may be a styrene-butadiene rubber, an acrylic rubber, or a polyvinyl chloride latex.  The web may be also impregnated with a water-repellent substance such as an alkylketene dimer, stearato-chromic chloride, a chromium complex of a fluorinated hydrocarbon or a chromium salt of a fluorinated acid, or with a bactericidal substance such as sodium pentachlorophenate, sodium orthophenylphenate, sodium orthophenylphenate, dibutyldithiocarbamate or silver oleate, or with both a water-repellent and a bactericidal substance.

Title: Improvements in or relating to phase delay devices suitable for multiplex telegraph systems
IPC: H04L5/22
Filed: 1939-10-31
Abstract: 533,352. Multiplex telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 31, 1939, No. 29092. Convention date, Nov. 1, 1938. [Classes 40 (iii) and 40 (v)] In distributer multiplex systems, and particularly channel extension systems, the phase of a repeated signal is determined by adjusting a shunt to an impedance in the input circuit of a gas discharge valve used in repeating the signal, and so determining the instant at which the valve strikes. Signals received over channel III of distributer 61 are repeated by a "locking unit" 62 to triodes A, B which repeat them to gasdischarge valves C, D controlling the output relay 23, whose armature 47 repeats the signals over distributer 55 to the outgoing circuit. The instant at which the valves C, D strike is determined by adjusting resistances 40, 43 around condensers 37, 41, or around inductances, Fig. 2 (not shown) in their input circuits. The striking point can also be adjusted by varying their grid bias or the capacity 44 across the anodes of the two valves. When the unit 62 makes lead 63 positive and lead 64 negative, valve A passes current and makes the grid of valve C negative. valve B being open and the grid of valve D positive, so that current passes through the lower winding of relay 23 and connects negative potential to the distributer 55, condenser 45 being charged so that its terminal 69 is positive relative to terminal 70. When the locking unit 62 reverses the potentials on leads 63, 64, valve B passes current and energizes valve C, current passing through the upper winding of relay 23 and reversing the charge on condenser 45, which stops the current through valve D.

Abstract: 1,015,367. Colour television. COMPAGNIE FRANCAISE DE TELEVISION. July 23, 1963 [July 25, 1962], No. 29203/63. Heading H4F. Relates to a colour television signal generating arrangement in which a scene S is illuminated by a cathode-ray tube flying-spot scanner 3 and viewed by photo-electric cells 51-53 to provide component colour signals on leads 61-63, the scene being additionally illuminated (for the convenience of actors and operators) by a flash tube 9 which is pulsed on during horizontal and/or vertical blanking intervals under the control of a unit 11 which provides all the necessary synchronizing and scanning signals and also controls amplifiers 81-83 to blank the component colour signals during the light flashes from tube 9. In accordance with the invention, the arrangement is also provided with a storage-type scanning camera tube 1 (e.g. an image orthicon or vidicon) which responds to the scene light due to the flashes from tube 9 and functions to provide a luminance signal on lead 65. An optical system 4 including a semi-transparent mirror 41 and lens system 40, 42 is arranged to image homologous points on the target of tube 1 and the screen of tube 3 on to the same point of the scene. Modifications are described in which the semi-transparent mirror is replaced by a pair of prisms with a semi-transparent interface, Fig. 2 (not shown), and a non-transparent mirror which is moved into or out of the light path during blanking (vertical) intervals by an electro-mechanical mechanism, Fig. 3 (not shown). Flash tube 9 may have an optical system and be combined structurally with the remaining of the arrangement to ensure an identical axis of illumination with flying-spot scanner 3, Fig. 4 (not shown). The component colour signals may be produced with reduced definition (with respect to the luminance signal) by (1) limiting the frequency response of amplifiers 81-83, (2) defocusing the spot of cathode-ray tube 3, or (3) emplying photoelectric cells with slow response. Only two component colour signals may be generated. One photo-electric cell may be used to generate a narrow band luminance signal.
