Title: Radio direction finder systems
IPC: G01S1/02
Filed: 1945-06-29
Abstract: 596,612. Radio direction-finding. STANDARD TELEPHONES & CABLES, Ltd. June 29,' 1945, No. 16653.. Convention date, Aug. 9, 1944. [Class 40 (v)] [Also in Group XXXVI] In a cathode-ray tube indicator for a radio direction-finder, when the direction-finder is aligned with the direction of the incoming signals the cathode-ray trace comprises a single linear trace or two separate colinear traces and the direction-indicating signals are applied to displace two portions of the single trace or the two separate traces relative to one another out of alignment when the directionfinder departs from alignment with the incoming signals. The invention is described as applied to a homing system in which the pick-up from a loop aerial 1, Fig. 1, is alternately combined in phase and phase-opposition with the pick-up from an open aerial 2 by means of two switching valves 3 and 4 which are alternately rendered conductive by push-pull voltages from the sinusoidal control source 8. The A.C. component of the rectified output from the receiver 5 which is applied to the Y plate 6 of the cathode-ray tube 7 thus comprises a sinusoidal voltage 23 or 24, Fig. 2, which is in phase or phase-opposition with the control voltage 10 according to the sense of the homing misalignment, the amplitude depending upon the magnitude of the misalignment. A sinusoidal wave 10 from the source 8 is applied to X-plate 15A and a square wave 14 derived from the sine wave is applied to the other X plate 15; these two waves are in phase, i.e. coincident positive half-cycles, and the resultant effect is equivalent to applying the composite waveform 16, Fig. 2, to X plate 15A so that in the absence of any signal on the Y plate two colinear traces 21, 22 are produced which are displaced out of alignment into position 21A, 22A when the output from the receiver comprises the voltage 23. The flybacks produced by the portions 17 and 19 of the composite waveform may be suppressed by blanking signals. In a modification, Fig. 3 (not shown), the composite waveform 16 is actually produced by mixing the waveforms 10 and 14 and applying the resultant to a single X plate. The switching valves 3 and 4 may be operated by the square wave 14 in which case the A.C. output from the receiver comprises a square wave, Fig. 7 (not shown), and the traces are displaced into positions 21B, 22B as shown in Fig. 4. In another modification, Fig. 5 (not shown), the two traces 21, 22 are produced by saw-tooth voltages and in Fig. 6 (not shown) a single trace is produced by a saw-tooth waveform of duration equal to a complete cycle of the control voltage 10, the two halves of the trace being then displaced as above.

Abstract: 545,386. Stoppers for containers. FREEMAN, W. S. Nov. 21, 1940. No. 16751. [Class 125 (iii)] In a stopper for a carboy, bottle, can or like container, the hinging member 14 about which the movable part of the stopper turns, is housed in a recess between two circumferential strips in the fixed part 13 of the stopper with an outer face which is completely uninterrupted. An axial perforation 38 in the part 13 reaches at its upper end to the top of the part 13 and the lip 37 is cut away to form a space 39 to facilitate the movement of the skirt 15 about the hinge 14. The circumferential strip 40 near the top of the part 13 is not interrupted but its inner. face forms one wall of the perforation 38. The recess extends downwards from this strip and terminates at the circumferential groove 180 thus leaving a portion 41 of the part 13 with an uninterrupted circumferential face. The lower part of the recess may be shouldered so that the hinge 14 is of T-shaped form or it may be angled in other ways. The hinge 14 may be secured by a staple 45 or may be cemented in position. Specifications 516,731 and 538,564 are referred to.

Title: A process for inhibiting corrosion caused by the presence of chlorine dioxide in apparatus consisting wholly or partly of stainless steel
IPC: D06L4/26
Filed: 1954-06-08
Abstract: Corrosion of apparatus comprising stainless steel components in which clorine dioxide or water-soluble chlorites are used, e.g. apparatus used in the bleaching of textile material, cellulose pulp, flour, oils or fats, is inhibited by introducing into the apparatus a mixture of water vapour and the vapours of nitric acid and an acid volatile in steam.  The chlorite or chlorine dioxide may be present in goods contained in the apparatus, e.g. in the bleaching of textile materials with aqueous chlorite solutions, and the acid-water-vapour mixture separately introduced, or goods containing a chlorite and an acid volatile in steam may be present in the apparatus, e.g. in bleaching textiles with acid-chlorite solutions, and the vapour from a boiling nitric acid solution separately introduced, or the apparatus may be used for a process, e.g. of bleaching, oxidizing or disinfecting, wherein chlorine dioxide and the acid-water-vapour mixture are introduced.  The acid volatile in steam may be hydrochloric, hydrobromic, formic, acetic, propionic, lactic or keto-butyric acid.  The chlorite may be of sodium, potassium or calcium.  Reduction of the nitric acid, e.g. with formic acid, may be prevented by the presence of urea or uric acid in the boiling solution from which the nitric acid is evolved.  The nitric acid may be liberated in the solution from its salts, using sulphuric or phosphoric acid.  Textile fibres, yarns or fabrics of natural or regenerated cellulose, polyesters, polyvinyl chloride, and polyacrylonitrile may be bleached by the process.  Examples refer to bleaching flour, sulphite pulp and cotton and viscose rayon materials.  Specification 696,967 is referred to.

Title: Improvements in or relating to axial piston hydraulic motors
IPC: F03C1/06
Filed: 1965-04-21
Abstract: 1,056,465. Hydraulic reciprocating motors. SIMIT S.p.A. April 21, 1965 [April 24, 1964), No. 16861/65. Heading F1A. In a swash plate motor, e.g. for driving a vehicle wheel, excavator or vane tower, having pistons 10 spring-loaded against a swash plate 11, the cylinders 9 communicate through piston bores 10a, check valves 24 and passages 21, 22 with the motor casing interior, which is connected to a source 30 of liquid under atmospheric pressure, so that when the load on the motor causes it to rotate at a speed greater than that induced by the supply, loss of contact between the pistons and the swash plate due to void formation in the cylinders is prevented by valves 24 admitting liquid from the casing. Braking action may be obtained by throttling the motor exhaust.

Title: Improvements in or relating to spring mechanisms, more particularly for the suspensions of vehicles
IPC: B62K25/20
Filed: 1942-11-27
Abstract: 561,659. Spring suspensions for motor cycles &c. BALLAMY, L. M., SHEEPSHANKS, R. H., and G.B. (NOTTINGHAM), Ltd. Nov. 27, 1942, No. 16912. [Class 136 (iii)] [Also in Group XXXII] A resilient suspension system for motor cycles &c. or other vehicles comprises a pair of telescopically - slidable members connected respectively with the road wheel or equivalent and the vehicle body or equivalent and urged apart by a main spring; the members being associated with crank or like mechariism which causes telescopic relative movement of the members to be accompanied by lateral move. ment relatively to the telescopic axis, the lateral movement being resisted by auxiliary resilient means. The invention is shown applied to the rear wheel of a motor cycle, the wheel 11 being mounted on lever arms 10 pivoted at 13 to a gear casing 14 forming part of the frame 15-19, a projection 32 on each arm being pivotally connected at 31 to a rod 28 carrying a piston 27 slidable in a cylinder 24, a main spring 26 being interposed between the piston and cylinder end 25. The cylinder 24 is separated by a rubber or like sleeve 34 from an outer cylinder 21 rigidly secured at its ends to the frame by brackets 22, 23, the sleeve acting as an auxiliary spring which resists lateral movement of the cylinder 24 as the pivot 31 travels along an arcuate path 33 with up-and-down movement of the wheel. The parts are shown in the positions adopted under normal static load, i.e. the rear component of the weight of the vehicle and rider, with the cylinder 24 eccentric to the cylinder 21. Increase in the load on the wheel further compresses the main spring 26 but decreases the stress in the auxiliary spring, which stress vanishes as the cylinder 24 becomes coaxial with the cylinder 21. The rubber sleeve 34, however, may be of. non-uniform thickness initially to allow the cylinder 24 to occupy an axial position under normal load with the sleeve under initial compression. In a modification, the cylinder 21 is dispensed with and cylinder 24 pivoted at its upper end to a fixed bracket and supported by an annular resilient cushion. Instead of a cylinder and piston use may be made, e.g. of a V-shaped guide fitted with a cross-head. Adjusting means may be provided for the main and/or auxiliary spring means and the latter may consist, e.g. of opposed compression springs bearing radially on the cylinder, or leaf springs having a similar action may be employed.

In the embodiment shown the contacting surfaces 11 of the member 5 and the rose are both spherical but in another embodiment an outer circular edge on the member 5 contacts a spherical surface on the rose and in still another embodiment the edge of the central aperture 12 in the rose contacts a spherical surface on the member 5. The cushion comprises a rubber or felt washer which fits tightly around the stem 1 and which may have a dependent flange fitting in gas tight manner between the member 5 and the stem. The cushion may have a spherical surface and it may comprise a part mounted in a recess in the collar and a contacting part mounted in a recess in the member 5. The collar 6 has two upstanding studs 8 which project into two radial slots 17 in a cover 14 for the rose whereby the collar is free to rock in any direction but rotation about a vertical axis is prevented. A flexible wire 19 connects the rose and collar electrically. The rose shown is adapted to be secured directly to a ceiling box but in an alternative construction the rose has a screw threaded hole in its upper surface for connection with a conduit extending downwardly from the ceiling and in this construction the rose may be fitted in inverted position.
