Abstract: 369,047. Ventilating enclosures. RICHTER, A., 7, VerlÒngerte Kolonlestrasse, Reinickendorf, Berlin. April 28, 1931, No. 12567. Convention date, May 28, 1930. [Class 137.] In ventilating apparatus for rooms or refrigerating chambers, the heat exchange device through which the air is passed alternately in opposite directions is constructed of thin light metal of good conductivity and is divided in the direction of flow into a plurality of zones to avoid heat conduction and the flow of deposited moisture. The heat exchange device b consists of an aluminium strip coiled spirally about a shaft c, distance-pieces d between the windings forming radial partitions. The device is divided axially into a number of zones by incisions f. In one method of ventilating an enclosure, two heat exchange devices are used and by means of a fan v<3> and dampers kl, k2, one device is used for the admission of fresh air and the other as the outlet. A movement of the dampers effects a reversal of the air current at short intervals. In a modification each heat exchange device is provided with a fan, the direction of rotation of the fans being simultaneously reversed at intervals. In a further modification a single rotatable heat exchange device is used and is divided into two zones z<1>, z<2> by means of stationary struts t<1>, t<2> at the ends of the device. One zone is used continuously as the inlet and the other as the outlet, the device being rotated about the centre shaft so that individual compartments of the device pass alternately into the two zones.

Abstract: 437,212. Photo-mechauical printing- surfaces. DROEGE, K., 34, Gartenstrasse, Frankfort-on-Main, Germany. April 30, 1934, No. 12961. Drawings to Specification. [Class 98 (ii)] The process of producing zincographic printing-plates in which a plate is coated with a layer of bichromated albumen, exposed under a drawing, flooded with transfer ink, developed, coated with shellac solution and the parts of the shellac layer overlying the ink removed by treatment with turpentine, the remaining shellac serving as an etching resist, is modified by the addition of colophony to the shellac solution, by the use of paraffin in place of turpentine for washing the plate and by the use of a mixture of three acids for etching. In carrying out the process a grained zinc plate is first de-oxidized with acetic acid and coated with a layer of albumen and glue sensitized with ammonium bichromate. After exposure it is coated with printer's black in turpentine and developed under water. A coating of shellac, colophony and methyl violet in alcohol is then applied and the plate washed in paraffin and cleaned with gum arabic solution. The albumen is then removed with dilute nitric acid, the plate cleaned with sulphuric acid, and etching is performed with a mixture of nitric, hydrochloric and phosphoric acids to which sodium bichromate is added.

Patent GB-132316-A (GB)
IPC: B64C11/36
Abstract: 132,316. Vessey, E. A. Aug. 30, 1918. Screw propellers.- In variable - pitch propellers of the type described in Specification 130,349, means are provided so that the axial component of the centrifugal force of the blade is taken independently of the shaft and the main thrust bearing. The flanged ring R, Fig. 1, corresponding to the retaining ring for the thrust bearing described in the earlier Specification supports a ball bearing 1. The bearing is retained between the ring R and a collar formed in the sleeve 2, which is free to slide axially in the case 3, but is prevented from rotating by a pin 4 engaging in a slot. The sleeve 2 carries an annular surface cam 5 which engages with a similar cam formed on a second sleeve 6, Fig. 3. Skew teeth 7 are cut on the sleeve 6 which engage with a worm 8 mounted in the case 3. The sleeve 6 is free to rotate in the bearing 12, but is prevented from moving axially by means of a collar 13. The sleeve contains a thrust bearing 15 which abuts against a shoulder formed on the adapter 16, or against a collar screwed to the boss of the main hub. The case 3 is attached to some fixed portion of the machine, such as a yoke spanning the end of the frame of an aeroplane. The spindle of the worm 8 is operated by gearing from a hand-wheel close to the pilot. When the propeller is rotating, the axial component of the centrifugal force of the blades is transmitted to the flanged ring R, which tends to move to the right. The force is transmitted through the ball bearings and cams to the collar 16, so that no axial force is transmitted to the main thrust bearing. The force beween the cams tends to cause a relative rotation, which is opposed by the pin 4 and the bevel-wheel 8 respectively. If the worm is rotated by the pilot in either direction, an axial movement of the sleeve 2 is caused, and thereby a variation in the pitch of the propeller. The movement of the bevel-wheel 8 involves only a small couple about an axis at right-angles to that of the propeller shaft. When the propeller comes to rest, the ring 2 moves to the left under the action of the balancing-spring and separates the cams, but without rotation of the cam 6, so that when the propeller is again started, it will take up the same pitch as before.

Filed: 1923-05-18
Abstract: 209,362. Clements, F. C. May 18, 1923. Treating soil with steam; manure distributors; rotary-tool implements; lifting tool frames manually; cleaning parts; motors, arrangement and control of.-Soil is raised from the ground, sterilized by steam, mixed with a fertilizer or manure, and replaced on the ground. The machine shown comprises an -endless chain k of buckets l which excavate the soil, raise it, and deposit it upon an endless band g of trays h. These pass first under a brush m or other appliance for cleaning the edges of the trays, and then under a perforated plate n forming the underside of a steam chamber j, through which steam from a boiler b passes sufficiently to sterilize the soil. The trays then pass under a hopper s, at the lower end of which is a star-wheel r rotated by the wheels o at the sides of the trays. This wheel r rotates a cylindrical valve in the base of the hopper, and thus delivers to the tray a definite quantity of fertilizer. As the tray turns over the rear wheel A<3> the soil is deposited. The buckets l have on their front edges blades or disintegrators for cutting up the soil as it is lifted. They may be raised clear of the ground by a screw v. The chain k and band g are driven by connections with the engine G, which also drives the machine over the ground. The trays are pressed up against the steam chest by springs q on bolts q<1> which pass through the tracks p upon which run the wheels o at the sides of the trays.

Title: Electrical comparator network
IPC: G06F7/02
Filed: 1957-04-26
Abstract: 836,237. Comparing digital data. WESTERN ELECTRIC CO. Inc. April 26, 1957 [April 27, 1956], No. 13352/57. Class 106 (1). A comparator network compares two numbers in reflected binary code by comparing each of the corresponding digits of the two numbers in a digit comparison circuit adapted to supply either one of two possible outputs to an output circuit and -reversing the output thus derived if there are an odd number of one of the two kinds of binary digits in one of the numbers being compared in positions of higher significance and applying to the output circuit the output from the digit comparison circuit which compares the digits of highest significance which are not of the same kind. The digits a 1 , b 1  of highest' significance of two reflected binary code numbers a 1 , a 2  . . . a n , b 1 , b 2  . . . b n  are fed to a circuit 100 which passes the digits if they are different but blocks them if they are the same. Circuits 110, 120, &c. operate similarly but are effective to reverse both their outputs if the number of " ones " in b 1 , b 2  ... b n  of higher significance is odd. Thus b 1  is fed to control the output of the circuit 110 and also together with its complement produced in the inverter 142 to the circuit 114 to which b 2  is fed over the lead 106. If b 1  and b 2  comprise an odd number of " ones " the circuit 114 provides a " one " output on line 117 and a " zero " on line 116, these conditions being reversed if b 1  and b 2  comprise an even number of " ones." A " one " on the lead 117 reverses the output of the circuit 120. A " one'" output on lead 123 is passed via the circuit 124 to produce an output at 140 under the control of the circuit 127 which is arranged to inhibit the action of the circuit 124 if a signal is received over the line 113 from the corresponding circuit 112 indicative of a final output having been passed to 140 at a comparison of higher significance. A signal on the lead 125 has a similar result. If a 1 , a 2  ... a n  is less than or equal to b 1 , b 2  ... b n  no output is observed at 140 but if this is not so an output is produced. Circuit arrangements for the various component units are described (Fig. 2, not shown). Specifications 663,872, 789,660, 836,234, 836,235 and 836,236 are referred to.

Title: Improvements in or relating to electric cables for trunk communication, particularly submarine cables
IPC: H01B7/14
Filed: 1937-05-11
Abstract: 491,105. Cables. SIEMENS & HALSKE AKT.-GES. May 11, 1937, No. 13425. Convention date, May 12, 1936. [Class 36] The conductors of a submarine cable have pressure-resisting insulation comprising three or more directly superposed windings of flexible bands of substantially incompressible insulating material, such as polystyrol, the bands being wound separately and preferably with a small gap between adjacent turns. Adjacent windings are preferably wound in opposite directions. To improve the transmission properties of the cable, a cord or string of pressure resisting material may be wound in open helical turns directly on the conductor and a similar cord may be wound over a band winding surrounding the first cord winding, the superposed band windings being applied over the second cord winding. The winding pitch of the cord or cords is preferably such that the gap between adjacent turns is less than twice the thickness of the cord. The spaces within the insulation may be filled with a liquid or semi-liquid insulating material, e.g. hydrogenized rubber. In the construction shown in Fig. 1, a conductor 10 is insulated by bandings 11-17 of polystyrol, over which is applied an outer conductor 18 consisting of good conducting bands held together by a binding 19. A lead sheath 20, which may be enclosed in armouring, completes the cable. The band winding 11, or both the band windings 11 and 13, may be replaced by an open winding or windings of substantially incompressible insulating material in string form. Fig. 4 shows a cable comprising conductors 41, 42 each insulated by a string-like winding 43 and superposed band windings, 44-46, the insulated conductors being stranded together with fillers 47, 48 and enclosed in an insulating wrapping 49, over which is applied a screen 50 and water-tight sheath 52.

Abstract: 234,517. Telefunken Ges. f³r Drahtlose Telegraphie. May 23, 1924, [Convention date]. Wireless signalling.-In a high-frequency circuit in which current is supplied to a frequencychanging transformer T from a generator G through tuning inductances and capacities L<1>, C<1>, L<2>, C<2>, inductance or capacity Cp is provided in parallel and its value is so chosen that the sum of the reactance of this branch and of the resultant reactance of the members L<1>, C<1> is equal to zero or is inductive in value. Preferably the resultant reactances of the members L<1>, C<1> and L<2>, C<2> are of the same sign, and that of Cp of opposite sign, and when the latter is capacitative, its absolute value is made less than that of the resultant reactance of L<2>, C<2>, whilst when Cp is inductive its absolute value is made less than that of the resultant reactance of L<2>, C<2>. The invention may be applied to signalling by varying the saturation of the transformer T bv direct current, and the choice of inductance and capacity values according to the invention is stated to produce cleaner signals and to permit quicker signalling.
