Title: Improvements in methods of balancing cable circuits
IPC: H04B3/30
Filed: 1924-06-05
Abstract: 239,577. Western Electric Co., Ltd., Mougey, W. E., and Collard, J. June 5, 1924. Induction, preventing and minimizing.-The susceptibility of telephone circuits to inductive disturbance from neighbouring circuits is diminished by balancing the series impedance and the admittance to ground of the two sides of each circuit, and this is effected by joining up the cable at the loading points so as to balance successively each part against the parts previously connected. The first section LS1 having been balanced, for example as described in Specification 2508/13, the unbalance of the circuits is tested with various cross-connections at the point B by applying a tone current at the second loading point C, a receiver being connected at the end A. Tests are made progressively along the cable, the receiver remaining at the end A. It may be desirable to work from both ends of the cable.

Title: Improvements in or relating to temperature control systems for electric heating devices
IPC: H05B1/02
Filed: 1943-08-25
Abstract: 586,593. Control systems for heating resistances. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 25, 1943, No. 13837. Convention date, Aug. 26, 1942. [Class 38 (iv)] [Also in Group XXXVII] An electric heating device, such as a blanket 10, has its temperature controlled in accordance with atmospheric temperature by a bimetallic element 25 controlling a snap-action switch 20 in series with the heating element 12. The element 25 moves the actuating member 24 of the switch as its temperature increases, regulation being provided by an adjustable stop 29. In the closed position of the switch 20, as shown, the element 12 and a resistance 30 for heating the element 25 are energized, whereby intermittent action of the switch 20 occurs. To render the apparatus inoperative in the event of folding or such misuse of the blanket as to cause an abnormal increase in its temperature, two oppositely flexing bimetal elements 32, 33 are hingedly coupled by a bridge 35, carrying a contact 36, and are heated respectively in proportion to the supply circuit voltage and the current in the element 12 when the switch 20 closes. An increase in the supply voltage will not disturb the balance of the forces exerted on the bridge 35, but abnormal heating of element 12 so changes its resistance as to cause contact 36 to engage a contact 39, whereby current is supplied through the switch arm 21 to a contact 23 in the next " off " position of the switch arm and heats portions of the heaters 30, 37 to maintain the-switch 20 in its " off " condition and contacts 36, 39 in engagement. Specification 554,987, [Group XXXVII], is referred to.

Abstract: Steroids having the partial formula <FORM:0811632/IV (b)/1> (wherein R is an acyl group and R1 is -NHCONHR2 or OR2 and R2 is hydrogen or an alkyl group containing from 1 to 4 carbon atoms) are prepared by reacting a 17a -hydroxy-20-keto-21-acyloxy steroid with a salt of a compound H2NR1 in the presence of a tertiary amine having a pKa value not greater than 7.6.  The reaction medium may contain water to solubilize the reactants, and preferably contains an aqueous mineral acid as catalyst.  Other reactive keto groups are attacked by the H2NR1 reagent, but may be protected, e.g. as cyclic ketals, prior to the reaction.  In examples: (1) cortisone acetate in dry pyridine (or containing 10 per cent water) is treated with hydroxylamine hydrochloride until product gives no colour with alkaline triphenyltetrazolium salts, and then diluted with water yielding cortisone acetate-3,20-bis-oxime; similarly (2) are prepared the 3,20-bis-oximes of 21-acetoxy - 17a  - hydroxypregn - 4 - ene - 3,20 - dione, 4,5a  - dihydrocortisone acetate, the 3,20 - bismethoxime of cortisone acetate (using O-methyl hydroxylamine) and the 20-mono-oximes of 3,21 - diacetoxy - 17a  - hydroxyallopregnane-11,20 - dione and (5) 21 - acetoxy - 3,3 - ethyenedioxy - 17a  - hydroxypregn - 5 - en - 11,20-dione; (3) cortisone acetate in pyridine is treated with aqueous semicarbazide hydrochloride, pyridine and concentrated HCl added and then aqueous sodium acetate yielding cortisone acetate 3,20-bis-semicarbazone; (4), (6) and (7), similarly are prepared the 3,20-bissemicarbazones of 21-acetoxy-17a -hydroxy-D 4-pregnene - 3,20 - dione, 21 - acetoxy - 17a  - hydroxy - 5a  - pregnan - 3,11,20 - trione, and dihydrocortisone acetate, and the 20-mono-semicarbazone of 3b ,21-diacetoxy-17a -hydroxy-5a -pregnan - 11,20 - dione; (8) and (9) 4,5a  - dihydrocortisone acetate in N : N-dimethylaniline or b -picoline is treated with semicarbazide hydrochloride in dilute HCl giving the 3,20-bissemicarbazone.

Title: Strapping apparatus
IPC: B65B13/08
Filed: 1963-04-09
Abstract: 994,501. Strapping apparatus. CARISTRAP INTERNATIONAL Ltd. April 9, 1963 [July 10, 19621, No. 14191/63. Heading B8C. Apparatus for facilitating the strapping of packages comprises a package support, a strap carrier with gripping means thereon, means for directing the carrier through a generally channel-shaped closed circuit passing beneath the package support, means for driving the carrier directing means, means for releasing the gripper when it is beneath the package and means for arresting the drive means when the carrier directing means has returned to its initial position. The strapping may be non- metallic. As described, the carrier directing means is an endless chain 15 trained about sprockets 16-21 and the strap carrier 61 is attached thereto. At the beginning of a cycle the carrier is in the position as shown in Fig. 1. Gripping means on the carrier comprising a wedge 65 and a foot 64, Fig. 4, are held apart by the operator turning a lever 71 anticlockwise. The operator feeds strapping material 74 between the wedge and the foot and then releases the lever. He also depresses a lever 45, Fig. 2, with his foot thus causing a platform 34 with a motor 33 thereon to pivot upwards thereby tightening a belt 31 to drive the chain 15 and the carrier 61 and pull the strapping material around three sides of the package. It also causes a link 46 mounted on the platform 34 to move upwards and thereby a slide 52 to move to the left as seen in Fig. 2 so that a slot 54 therein can engage the shouldered portion 59 of a lever 55, Fig. 5. This keeps the platform 34 in its raised position. The motion continues until the lever 71, Fig. 1, is contacted by a fixed member 79 causing the strap 74 to be released and swing out to the position 74<SP>1</SP> where the operator can take hold of it and complete the strapping operation manually. The strap carrier then continues until a cam 80 on the chain 15, Fig. 5, contacts the lever 55 thus releasing the slide 52 and returning the platform 34 to its lowered position. This stops the apparatus but the strap carrier is carried by momentum to its original position for the start of another cycle.

Abstract: 667,356. Valve amplifying and generating circuits. STANDARD TELEPHONES & CABLES, Ltd. June 9, 1950, No. 14430/50. Class 40 (vi). In an ultra high-frequency generator or amplifier, two coaxial resonators comprising inner and outer conductors are arranged at an angle with the conductors of one resonator connected to the anode and cathode and the conductors of the other connected between anode and grid of a valve having aligned planar electrodes. By adjusting the effective length of the resonators, the valve may be made to operate as a generator or amplifier. The anode 2 of the valve is earthed for high frequency through an insulating ring 5 arranged between the anode and the outer cylinder 8 of the output line, the inner conductor 13 of which is connected to the cathode 4. The grid is connected through a resistor 16 to a biasing source and is coupled through capacitor 15 to the inner conductor 12 of the input line 9. When operating as an amplifier the input is applied to the coupling loop 21, energy being taken from the anode circuit off coupling loop 19 to give a low impedance output. The frequency of operation may be varied by adjusting the plungers 18, 17 and for a given frequency, plunger 17 is brought out beyond the resonant position to give an inductive effect. When operating as a generator, plunger 17 is pushed in to give a capacitative effect.

Abstract: 165,086. Stromberg Motor Devices Co., (Assignees of Mock, F. C., Gustafson, C. J., and Chandler, M. E.). June 12, 1920, [Convention date]. Spray carburettors.-The opening of the throttle valve of a carburettor used on an aeroplane is limited by a barometric device so that the opening cepends on the atmospheric conditions. In one arrangement a bellows expanding under reduced atmospheric pressure moves a stop in the path of the throttle lever. In a modification, the bellows 56, Fig. 2, adjusts the bell-crank 75 which carries the pivot 80 of the throttle lever 79. This lever acts on the valve through a pin-and-slot mechanism; stops are provided to limit the movement of the crank 75, throttle lever and the valve. The Specification as open to inspection under Sect. 91 (3) (a) also describes a throttle control in which the bellows 99, Fig. 5 (Cancelled), is contained in a sealed chamber 97 connected by a pipe 98 to the intake manifold. A rod 104 is screwed to the end of the bellows, and its movement is limited by the adjustable screw 106. Two sleeves 114, 116 with an interposed spring 118 are carried on the rod 104, the sleeves being connected by crank-shafts and links to the throttle valve 92 and control lever respectively. This mounting of the bellows prevents excessive opening of the throttle valve at low speeds. This subject-matter does not appear in the Specification as accepted.

A cotton gin has means for removing inadequately ginned material from a feed roller and returning it to a feeding position. The feed roller 43 transfers material from the hopper 9 to the area of knives 49, 56 and ginning roller 42. Cotton and seeds carried around with the feed roller 43 are caught by a sawtoothed roller or a spiked separator roller 36 that causes separation of seeds from each other and from adhering linters. Freed linters are doffed by a reclaiming brush 38 and thrown back into the hopper 9. Separated seeds drop through gratings 62, 63. In order to retain stationary knife 49 against the face of the ginning roller 42, hydraulic mechanism is provided including cylinders 53 and piston-rods 54. A feed control vane 68 is biased away from a stop bracket 71 and is associated with a switch in such manner that, when the vane 68 is pressed down by weight of cotton, delivery of material to the hopper 9 from an independently driven delivery unit is stopped. An hydraulic control system for this independent delivery unit is described.

Abstract: 1, 055, 508. Radiometers. LABORATOIRES D'ELECTRONIQUE ET DE PHYSIQUE APPLIQUEES L. E. P. April 7, 1965 [April 9, 1964; March 30, 1965], No.14740/65. Heading G1X. A radiometer gauge which may be used in the determination of low pressures comprises a graphite disc 1 levitated by means of a magnetic field inside a glass tube 7 which forms the hot source for the radiometer a screen 6 consisting of four assemblies 2, 3, 4, 5 symmetrically arranged so that molecules accelerated from the source 7 exert a couple on the disc 1 causing it to rotate about its axis, the unwanted effects of infrared radiation from the source 7 being cancelled. The assemblies 2, 3, 4, 5 are arranged to provide four apertures 21, 31, 41, 51 and with the disc 1 in the position shown in Fig. 1 molecules from the source 7, represented by dotted lines, can pass through the apertures 21 and 41 to impinge on the disc 1 but only on one side of axis 10 so that a couple is exerted on the disc 1 tending to rotate it in an anticlockwise direction as viewed in Fig. 1. Molecules from the apertures 31, 51 will impinge on the disc as it rotates from the position shown but again only to one side of the axis 10 so that a continuous couple is exerted on the disc and it will rotate at a speed dependent on this couple and thus on the pressure of the gas inside the source 7. Infrared radiation, represented by wavy lines, also impinges on the disc 1 by way of the apertures 21, 31, 41, 51 and exerts an unwanted couple on the disc 1. This is compensated for by the provision of windows, such as 22, 23 of silicon or germanium, which transmit infrared radiation and allow such radiation to impinge on the disc 1 on the side of the axis 10 so as to cancel the couple caused by radiation from the apertures 21, 31, 41, 51. The size of the windows is such as to fulfil this condition. The screen 6 is held at a constant temperature below that of the source 7, and the evolutions of the disc 1 are counted by use of a lamp 201 and photo-multiplier 203 connected to a counter circuit.
