Title: Improvements in diving devices for use as toys or for advertising purposes
IPC: A63H23/08
Filed: 1933-10-19
Abstract: 416,958. Moving signs. HERBST, P., 32, Bruckenstrasse, Bremen, Germany. Oct. 19, 1933, No. 28980. [Class 3 (i).] A device for use as a toy or for advertising purposes comprises a diving body in a water container and adapted to rise and sink by the alternate admission and discharge of air into and from the body under the control of the body itself. In the construction shown in Fig. 1 the diving body in the form of a boat 9, with air compartments 11 and water passage 12, on sinking strikes the float or spring supported ends 7 of the levers 4, 5, which are fulcrummed on knife edges, to rotate them and open the valve 3 to allow compressed air entering through the nipple 22 to enter the passage 12 through the perforated plate 20 to displace the water. The boat 9 then rises and the valve 3 closes. When the boat 9 reaches the surface, water in the chamber 18 escapes through an aperture 17 and the float 13 falls to open the valve 14 and allow the air in the passage 12 to escape, water entering from below to cause the boat to sink. The upper part of the passage 12 may be enclosed in a tower 16 with apertures 15 for admission and discharge of water. The sizes of the aperture 17 and the valve stem 3<a> are selected to give the required times of stay on the water surface and bottom of the container. A buoyant figure 19 rises and falls with the water and can be seen through the boat 9 and passage 12 which are of transparent material. Lateral movements of the boat are constrained by the walls of the container 1. Advertisements may be applied in suitable positions and the configuration of the container 1 and the figure 19 can be varied to suit the advertisement. In the construction shown in Fig. 2 the diving body drops on to plate 27 to actuate the valve 3, and the air admission into the valve chamber 26 is retarded by the provision of a reducing element comprising a tube 23 containing felt discs 25 alternating with perforated metal plates 24. In the construction shown in Fig. 3 the diving body is in the form of a human figure 9<a> under which air is discharged from the chamber 21 through the inclined tube 29. The head 32 is loosely mounted and acts as a float controlling a valve similar to the valve 14 of Fig. 1. In the construction shown in Fig. 4 the diving body has a bevelled or conical foot 31 for spreading apart the blade springs 30 and allowing the valve 3 to open under air pressure.

Title: Improvements in or relating to water carbonating devices
IPC: B67D1/00
Filed: 1943-02-13
Abstract: 606,531. Automatic control systems.  COCA-COLA CO. Feb. 13, 1943, No. 28999/45. Convention date, Jan. 15, 1942. Divided out of 606,497, [Group XVIII]. [Class 38 (iv)] [Also in Group II] Liquid level. A water-carbonating device comprises a container in which a rotary agitator assists mixing of water and carbon dioxide supplied through separate inlets, and means responsive to the liquid level for controlling the admission of water and for stopping and starting the agitator. Water is supplied to a container 35, Fig. 2, by a pump driven by an electric motor connected by lines 418, 419 to mains 40, 41. Rods 400, 401, enclosed in a perforated chamber 408, dip into the liquid in the tank 35 and are connected to a low voltage relay 415 which when energized holds a switch arm 416 away from a contact 417 in the line 418. When the carbonated water is withdrawn from the chamber 35 and the level falls below the line A the relay 415 is de-energized and the switch 416, 417 closes to start the pump motor which drives also a rotary agitator comprising vanes 376 on a shaft 375. The agitator produces a vortex raising the level of liquid adjacent the shaft and lowering the level in the chamber 408. Owing to its inertia the relay 415 will not be again energized until the liquid rises to a level C. Thus a substantial quantity of liquid is added to the chamber 35 between the starting and stopping of the pump. In a modification, Fig. 3, the chamber 408 contains a float 450 which carries transverse arms 456, 463 on a vertical rod 455. When the liquid level falls the arm 463 depresses a pivoted lever 457 to break a switch 460, 461 and deenergize the relay 415. When the liquid rises again the arm 456 operates on the lever 457 to energize the relay and stop the pump.

Abstract: 826,043. Parachutes. MINISTER OF SUPPLY. Dec. 19, 1957 [Sept 21, 1956], No., 29019 / 56. Class 4. The canopyof a main parachute (not shown) is stowed in a sleeve or sock 11 which has a small parachute 13 or other drag means at one end and is releasably connected at its other end to a load harness 14. As shown, a length of webbing 15 is secured to a fabric sock and extends along opposite sides of the sock to form a loop 16 to which the rigging lines 12 of the parachute 13 are attached. The webbing 15 extends below the sock and forms two strops 17 attached by. any known releasable means 28, 30 and 29, 31 to double lift webs 26, 27, each passing through two slots of a four slot buckle 24, 25 and being attached below the buckle to a main double lift web. 22, 23 respectively, the main lift web being attached to the. load harness. A tongue 18 on the sock is provided with loops (not shown) in which the rigging lines (not shown) of the main parachute are stowed, these lines connecting the main lift webs 22, 23 to the main parachute canopy inside the sock. The tongue is rolled up and secured by frangible ties 21 as shown in Fig. 2. The sock is folded zig-zag fashion with the small parachute in a pack. In use, the small parachute is deployed, and serves to stabilize the descent and maintians the sock extended. The rate of descent is high at a desired altitude, e.g. 15,000 feet in the case of a human load, the fastenings 28, 30 and 29, 31 are released manually or automatically, e.g. by barometric means. The resulting pull on the main lift webs 22, 23 breaks ties 21, and the tongue 18 unrolls. Parachute 13 draws the sock off the main parachute canopy, which develops. The releasable fastenings 28, 30, and 29, 31 may be between the strops 17 and the main lift webs 22, 23, in which case the webs 26, 27 are unnecessary. The small parachute 13 may be replaced by a drag device of downwardly tapering form.

Title: Improvements in and relating to measurement of electric fields in waveguides
Inventor: WILLIAMS THOMAS ARTHUR KENNEDY
IPC: G01R29/08
Filed: 1953-10-21
Abstract: 757,402. Waveguides. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 20, 1954 [Oct. 21, 1953], No. 29079/53. Class 40 (8). [Also in Group XXXVI] Apparatus for measuring a transverse electric field in a waveguide of circular cross-section comprises a section of rectangular waveguide coaxial with and axially rotatable with relation to the circular waveguide, and from which extends diametrically into the waveguide and collinear with the major axis of the rectangular section a load member adapted to absorb all the energy of the transverse electric field which is polarized in the plane of such load member, the remaining energy in the transverse field normal to the plane of the load being determined by a detector positioned in the section of rectangular waveguide, which supplies a current-measuring instrument. A fixed circular waveguide 1 is aperture coupled to the wider face of a rectangular waveguide 2 and carries coaxially therewith a further rotatable circular waveguide 3, which is terminated in a rectangular waveguide 4 whose major axis is also coaxial with the circular waveguide. Mounted diagonally across the circular section 3 coaxially with the rectangular section 4 is a lossy load 6 (e.g. a carbon strip) which absorbs all the energy in the field along the plane in which it is located, leaving the energy in the field in space quadrature therewith unabsorbed. The latter energy is determined by a measuring instrument supplied by a crystal detector 7 coupled into the rectangular waveguide section 4, so that by rotation of the waveguide section 3 the energy of the electric field in section 1 (and by suitable coupling, that in the rectangular section) is determinable in any angular position. Specification 592,224, [Group XL], is referred to.

Abstract: 451,012. Rubber films and sheets. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter Port, Guernsey. Oct. 22, 1935, No. 29126. Convention date, Nov. 28, 1934. [Classes 70 and 87 (ii)] Rubber film or sheets having perforations or having protuberances on the surface, are made by spraying latex, or other rubber dispersion, on to a perforate backing, coagulating the latex on the backing, and removing the coagulated deposit. Depending on the viscosity of the dispersion and the rate of spraying, the deposit either passes through the holes, forming a perforate sheet having protuberances round the perforations, as shown in Fig. 4, or films over the holes forming projections having concave ends as shown in Fig. 8. If a sheet having projections round the perforations, as shown in Fig. 4, is used as a backing, a plain perforated sheet free from protuberances, as shown in Fig. 6, may be formed. Colour effects may be obtained by spraying first with a latex of one colour to form a perforated sheet and then with latex of another colour to film over the holes.

Abstract: 893,254. Electric selective signalling systems. SQUARE D CO. Aug. 25, 1960 [Sept. 24, 1959], No. 29325/60. Class 40 (1). In a positioning-system a transformer primary 26, Fig. 5, is divided into two sections 26L, 26R by connecting the ends 42L, 42R to one terminal of an A.C. source 38 and connecting a tapping 30 to the other terminal of source 38, switches 52, 36, 54 and lumped inductances 44, 46 ensuring that the inductance of the two sections 26L, 26R remains constant for all tappings 30 so that voltages induced in the secondary winding are symmetrical when the secondary is in a predetermined axial position with respect to the selected tapping 30, and the phase of the voltage induced in the secondary winding is detected to effect positioning of the secondary winding with respect to a selected tapping 30. The secondary winding is normally driven to a point where its centre is opposite the selected tapping, but the final rest position may be offset by making the current in sections 26L, 26R different by means of resistors 56, 60. The secondary winding may be driven to one of 1000 equally-spaced points between a selected tap and an adjacent tapping by reducing the voltage applied to section 26L, for example by means of the three precision ratio transformers T1, T2, T3. The detection circuit comprises a voltage sensitive relay 82, Fig. 7, which releases when the error voltage drops to a given value, contacts of relay 82 then operate a slow-down circuit for the motor driving secondary winding 28, and applying H.T. to thyratron 102 through relay winding 100. The output of winding 28 is squared, differentiated and applied to grid 108. A reference alternating voltage is fed through phase-shifting network 126 to squarer 136 and differentiator 138 to grid 110. Thyratron 102 is arranged only to fire when the pulses applied to grids 108, 110 coincide, whereupon relay 100 operates to stop the motor. Network 126 allows further zero offset to be introduced. Further secondary windings, spaced from winding 28 may be provided, these further windings being caused to actuate further slow-down circuits as the desired position of winding 28 is approached.
