Title: Improvements in Apparatus for Delivering Gas.
IPC: A62B7/14
Filed: 1919-03-13
Abstract: 129,623. Van Sicklen Co., (Assignees of Prouty, T. C.). July 11, 1918, [Convention date]. Inhalers &c.-The gas from a high-pressure reservoir is first passed through a reducing-valve to bring it to, say, 50 lb. per sq. in. pressure, and is then passed through a secondary reducing-valve controlled by an aneroid device which is fitted with differential mechanism to give an increased proportionate supply of oxygen as the air becomes more and more rarefied. The first reducing-valve is shown at 17, the cap 19<a> of which constitutes a relatively heavy diaphragm. This is secured centrally to a disk 37 connected to a U-shaped bar 36 carrying a cone valve 33, preferably of amethyst. This valve is normally open, but when oxygen is admitted through the pipe 24 and passage 28 and thence passes by the valve to the chamber 22, and the pressure in this chamber rises to the pre-arranged limit, the diaphragm 19<a> is moved outwards and the valve is closed, The cap 19 screws on to the body 18 and is secured by a lock-nut 20, a lead gasket 21 being inter. posed. The yoke 23 having the passages 28, 90 is secured to the body 18 by nuts, as shown. The chamber 22 communicates by the passage 30, the pipe 41 and connexion 57 with the secondary reducing-valve 42. When the cone 61 of this valve is open, oxygen can pass from the connexion 57, through the valve, into the chamber 49, and so to the aviator's mask by the connexion 56. The cone 61 is connected by the U-bar 62 to the disk 46 which is secured to the flexible diaphragm 45, and it is kept normally to its seat by springs, partly seen at 64. The valve is opened by the aneroid 69 which bears 'against the centre of the diaphragm 45, a leaf spring 72 being interposed between the two. The other side of the aneroid rests against a yielding resistance which becomes greater as the aneroid expands, so that the portion bearing against the diaphragm 45 moves proportionately through a greater distance, the more rarefied the atmosphere becomes. The yielding resistance consists of a lever 77, Fig. 2, acting through the ball 83 on the aneroid and bearing at its other end on the spring 86. Its fulcrum is formed by the contact point of the curve 78, and the framing 79. As the aneroid expands, this curve rolls on the framing, and the contact point moves nearer the end bearing against the aneroid. The apparatus is arranged to begin action at an altitude of 5000 ft. If the static pressure of the oxygen in the chamber 49 increases, the valve 61 will close. The variation of volume of oxygen delivered is effected not by varying the amount of opening of the valve, but by varying the time during which the valve is open. The valve makes rapid reciprocations with a very limited amplitude of stroke.

Title: Improvements in and relating to electromagnets
IPC: H01F7/12
Filed: 1922-03-03
Abstract: 196,152. British Thomson - Houston Co., Ltd., (General Electric Co.). March 3, 1922. Electromagnets.-To prevent chattering and to eliminate residual magnetism in an electromagnet operated by alternating or intermittent currents, at least one of the pole-pieces is formed of conducting material in which magnetic members are embedded, and means are provided for preventing eddy currents from circulating around some of the members. The moving armature comprises a rod 15 of magnetic material and a smaller nonmagnetic rod 16 which passes through the stationary pole-piece 11. Between the two rods is a pole-piece 17 of copper or aluminium, cut, as at 24, to prevent the circulation of currents around the ring as a whole. Magnetic studs 18 - - 23 are secured in the ring, which is slotted at alternate studs 18, 20, 22. Since the studs 19, 21, 23 are surrounded by conducting material, out-of-phase fluxes are induced therein, and the adjacent non-shaded studs provide return paths. An air-gap is provided in the local circuit by countersinking the ring 25.

Title: Improvements in or relating to plug cocks
IPC: F16K5/16
Filed: 1940-04-09
Abstract: 540,374. Plug-cocks. MACHIN, F. R. April 9, 1940, No. 6398. [Class 135] A plug-cock has the plug eased from its seat prior to rotation by the co-operation of a radial pin in a spindle coaxial with the plug with inclined surfaces on a member rotated during actuation. In the 'form shown in Fig. 1 the plug 2 is normally held to its seat by a spring 4 and is unseated by the engagement of the end of an actuating spindle 14 with the head of a screw 15 secured to the plug. The spindle 14 carries a diametral pin 16 held by a spring 20 in a groove in a member 10 mounted on the end of a sleeve 5 rotatably mounted on the casing and rigidly secured to a tubular spindle 1 connected at 3 to the plug so as to allow relative axial movement. When the handle 13 is turned the pin 16 first co-operates with inclined surfaces on the bottom of the groove in the member 10 so causing the spindle 14 to move inwards to unseat the plug. The plug is subsequently turned by the engagement of the pin with stop surfaces on the sides of the groove. Friction in the stuffing-box 1<SP>1</SP> and the resistance of a spring catch 17 holds the spindle 1 stationary during the initial operation. The Provisional Specification, however, describes a modification in which the sleeve 5 is made axially slidable and is provided with an interrupted flange engaging recesses in the casing to provide a positive lock. In a modification the pin 16, which may carry anti-friction rollers, is mounted in a spindle rigid with the plug and co-operates with a groove having inclined and stop surfaces formed in a bush secured to a rotary actuating handle. Specification 522,769 is referred to.

Title: Improvements in or relating to controlled humidity refrigerator
IPC: F25D17/02
Filed: 1945-03-15
Abstract: 601,455. Refrigerators. PHILCO RADIO & TELEVISION CORPORATION. March 15, 1945, No. 6527. Convention date, March 29, 1944. [Class 29] A high: humidity food storage compartment 5 of a refrigerator is cooled by a secondary evaporating-condensing refrigerating system 19 around the walls 4 of the compartment to maintain it at non-frosting temperature, and the compartment air is circulated by a fan 31 over the primary evaporator 25 under the control of a humidostat 32 in the food storage compartment. Fig. 3 shows the inner shell 4 of the refrigerator, which is enclosed in insulating material and an outer casing 3. A sharp-freezing storage section 13 of the well type accessible through a door 15, and an ice-making compartment 16 are cooled by the primary evaporator pipes 22, 26, 25 fed from the condenser through a capillary tube 23. The primary evaporator is extended by a pipe 27 to an evaporator element 20 forming the condenser of the secondary refrigerant circuit 19 surrounding the food chamber 5. When the humidity in the food chamber increases beyond the desired value the fan motor 30 is started by the humidostat 32 and draws air from the food chamber through a lower slot 35 in the rear wall of the chamber and through a casing 42 surrounding the ice-making compartment 16 and delivers the cooled air through a half-round conduit 29 welded to the inner shell 4 to an inlet slot 37 at the upper part of the rear wall of the chamber. Excess moisture in the air is condensed by the primary evaporator 25 and is collected in a sump 46 from which it is fed to the compressor 12 and vaporised, thus cooling the compressor. To prevent frosting in the casing 42 a layer 45 of insulating material is interposed between the evaporator pipes 25 and the finned wall 44 of the ice-making unit. The food storage space is separated from the low temperature compartments by a double insulating partition 17 with gaskets 18 contacted by the door when closed. Specification 601,448 is referred to.

Title: Improvements in or relating to electron discharge devices employing hollow resonators and to circuit arrangements including such devices
IPC: H03D9/06
Filed: 1941-05-21
Abstract: 577,173. Discharge apparatus. BULL, C. S. May 21, 1941, Nos. 6529 and 14982. [Classes 39 (i) and 40 (iii)] A diode for mixing high.frequency oscillations is formed from parts of a resonator, the primary cathode being external to the resonator. In one form, the cathode 5, Fig. 1, projects electrons through an aperture in the wall 6 of the resonator which is biassed positively to act as an accelerator. A re-entrant portion of the other wall 7 at a lower potential than the accelerator acts as the anode of the diode ; the high-frequency field extends right to the anode, as distinct from known arrangements in which the reflecting electrode is outside that field. Both the received and local frequencies may be injected into the resonator by loops 11, or one may be applied across parts 6, 7 or between cathode 5 and wall 6. An insulating layer 8 isolates parts 6, 7 for direct and beat frequency currents. The resonator is here broken at a current antinode and to avoid this the anode may be a cylinder coated with insulation, for example by anodizing, and inserted into an aperture in an otherwise unbroken resonator. Breaking the resonator may be avoided altogether by a balanced arrangement in which a cylinder anode 20, Fig. 4, is placed within a complete resonator 17 and receives electrons from independent cathodes 19 on each side. The beam may be velocity modulated before entering the resonaator by additional resonators 22 interposed between cathodes 19 and walls 18. In a inodification, Fig. 5, the end-wall 27 and central conductor 26 of a coaxial line resonator 25 are sealed through the envelope 28 and form accelerator 29 and anode 30 respectively. Tuning is effected by a sliding piston or by a dielectric tube 31 sliding over the central conductor 26. The tapping connection 33 may slide along the conductor 26, the outer wall being slotted for this purpose. In another form the central conductor is bent round to provide an anode at each end, supplied from a common cathode. To avoid disturbances due to stray magnetism, the resonator parts near the electron stream axe either of non-magnetic material or are subjected to a special de-magnetizing treatment after assembly.

Abstract: 1376016 Manipulative toys TANKERTON PLASTICS & ENG CO Ltd and B C KIRKLAND 14 May 1973 [14 Feb 1972] 6717/72 Heading A6S A balancing and timing manipulative toy comprises a pole 10 having at one end a time indicator 16 powered by a clockwork, &c motor 19 driving through a coupling 23 which becomes automatically disengaged if the inclination of the pole to the vertical exceeds a limiting angle. In play, the toy is used to see for how long a child can hold the pole 10 upright. The coupling 23 depends from a mass 22 in the form of a ball balanced in the shallow concave top 15 of a housing 13 fast with the upper end of the pole 10. The time indicator 16 consists of a disk journalled for rotation by a pin 17 about the top end of the pole 10 within the housing 13, and having numerals 7, &c around its periphery visible one at a time through a window 18 in the housing wall. An upwardly extending pin on the time indicator disk 16 fits freely into the coupling 23, which travels around an arcuate slot 24 extending about the centre of the hollow, concave housing top 15. The motor 19 has a square winding spindle 21 sliding freely but non-rotatably into a complementary hole in the ball 22. The clockwork motor 19 is wound by turning the ball 22. The motor 19 then drives through the ball 22 and the coupling 23 to the time indicator 16. If the pole 10 is inclined to the vertical, the ball 22 falls out of the concave housing top 15, so disconnecting the coupling 23, and stopping rotation of the time indicator 16. As a modification, the motor 19 may alternatively be battery powered.
