Title: Improvements in or relating to ornamented candles
IPC: C11C5/02
Filed: 1938-06-09
Abstract: 507,379. Ornamental candles. CASSIMATIS, I., and STRATEGOS, H. June 9, 1938, No. 17106. [Class 91] Candles are ornamented with a pattern or marking in ink or similar coloured material, which does not interfere with the burning of the candle, and which is integral with the body of the candle. The marking is pre-formed on a flat strip of celluloid or similar non-porous material over which is placed a stencil, and ink is applied thereto by a printer's roller to form markings on the celluloid strip. The celluloid strip is then rolled into a cylinder 14, Fig. 2, with the marking 13 inside, and inserted in a former 15 made of a closed inner tube 19 and an outer enclosure 18 having straps 24 and wing nuts 25. A wick is then centrally inserted and a conical closure attached to the lower end forming a candle mould. Molten wax is then poured into the mould while the ink on the cylinder 14 is still wet, and the mould is then chilled in water. The' outer tube 18 is then released and the ornamented candle 29, Fig. 8, is removed.

Title: Improvements in or relating to sound recording and reproducing devices
IPC: H04R9/12
Filed: 1935-06-14
Abstract: 438,334. Sound recording and reproducing machines. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Keller, A. C., 3, Park Lane, Mount Vernon, Rafuse, I. S.; 19, Kathryn Place, Hempstead, and Harrison, H. C.; 94, Bayview Avenue, Port Washington, all in New York, U.S.A.) June 14, 1935, Nos. 17141 and 17142. Convention dates, June 20, 1934 and Dec. 29, 1934. [Class 40 (ii)] A sound recorder or reproducer having a stylus co-operating with a record surface is supported relatively to the surface by means of a fluid-pressure device which enables the " advance ball" usually provided for regulating the depth of cut in recording to be dispensed with, and which is also of advantage for play-back devices for reproducing original recordings made in wax. The recording or reproducing device 11 carries a fluid conduit 14 provided with a flange 18 adapted to be maintained in close spaced relation to the record surface 22 by the flow of fluid between the flange and the surface 22. In the recording- device shown, filtered air is supplied under pressure to the conduit 14 through a control valve 17 and a flexible tube 16. The depth of cut may be regulated partly by varying the air pressure and partly by adjustment of the tube 14 by a differential screw 25. Various modifications in the design and arrangement of the flange, including devices for deflecting the air flow from the stylus, are described. A construction of recorder is described, in which the air conduit is attached to an arm adjustably mounted on the side of the recorder and provided with two outflow orifices, either one of which is closed by a plug, whilst the flange member is screwed to the other orifice. This arrangement enables the air outflow to occur ahead of the stylus whether the direction of movement is inwards or outwards across the blank. A mechanical advance ball may be substituted for the flanged fluid-outflow member if desired. Instead of using compressed air or other gas, a liquid such as water may be used, e.g. if recording is carried out with the blank submerged in water to prevent the accumulation of dust.

Title: Improvements in the production of cyanogen compounds, ammonia and the like
IPC: C01C3/00
Filed: 1918-10-21
Abstract: 140,484. Calvert, G. Oct. 21, 1918. Alkali cyanides; cyanogen compounds.-In the production of cyanogen compounds by the action of nitrogen on a mixture of an alkali, carbon, and a catalyst such as iron at 900-1100‹ C., the solid materials are continuously commingled by mechanical means arranged within the reaction chamber. The apparatus may consist of a spherical retort 1 set in a gas furnace 2 and containing stirrers 13 of unequal length on a shaft 16. A framework 75, Fig. 2, with partitions 76 may be provided to prevent agglomeration of the charge, the stirrers 13 passing between the partitions. The charging-tube 5 is closable by a conical valve 8, 9 controlled by a rod 10 carrying a hand-wheel 12, and the discharge is effected by a slide 24 and cap 28. Tubes 74 may be provided for thermometers. In another form of apparatus for continuous operation, the retort is of cylindrical form, Fig. 3, and the stirring-blades are portions of right and left handed screws, so as to convey the charge slowly to the discharge 45. The nitrogen is admitted from a pipe 37 opening into the charging- tube, and the gas-exit pipe 47 opens into a water tank 48. The stirring-blades may be arranged to pass between stationary knives fixed to the inside of the' retort to prevent agglomeration of the charge. The retort in both forms is constructed of nickel-chromium alloy. The catalyst may be first placed in the retort in excess and the remaining charge gradually added, or an excess of alkali carbonate may be used, so that the other ingredients are maintained in suspension in it. Alternatively, the alkali, which may be in the form of metallic sodium, may be introduced in a molten or gaseous state, and the carbon may be in the form of carbon monoxide. Inert material, such as carbon or powdered nickel-chromium alloy, may be added to the charge to prevent agglomeration.

Title: Improvements in or relating to radiation sources
Inventor: HOLLAND WILLIAM HENRY
IPC: G21G4/06
Filed: 1960-05-16
Abstract: 917,878. Radiation sources. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. May 5, 1961 [May 16, 1960], No. 17281/60. Class 98 (1). [Also in Group XL (a)] A radiation source comprises a number of closed containers holding radiactive material mounted in a tiltable frame member, the frame being latchable in a vertical position (which is the operative irradiating position), and the latch releasable so that the frame can be tilted into an inclined (loading and unloading) position. In the form shown, the containers are closed cylinders 16, mounted side-by-side in a rectangular frame whose top consists of T-section members 6, 7 and whose bottom is an apertured semi-cylindrical member 8. The bottom of the cylinders are tapered, as at 17, so as to be located within-the aperture in member 8. The latter rests on and pivots on bearing pads 11. When the frame is tilted into the vertical position it is located within an outer frame having top and bottom sections 2, 5, and vertical side sections as at 4. The inner frame is maintained in a vertical position, when so required, by a latch 15. This is the operative position, when packages may be brought up against the frame for irradiation. For loading, the inner frame is unlatched and tilted into the inclined position shown in Fig. 3. An alignment frame 25 has a series of channels 26 in alignment with corresponding channels in the inner frame. A tubular container 16 is placed in a channel 26, and allowed to slide down gently until it rests on T-member 7. The inner frame is then tilted a little towards the vertical (by means of a lever 30) until the container slides between members 6, 7 and the lower end enters into member 8.
Patent GB-172974-A (GB)
Abstract: 172,974. Krone, J. Dec. 17, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Finders.-A combined view-finding and focusing attachment comprises an optical system producing an image on a ground-glass screen, and means operatively connected to a part of the camera that moves during focusing, (1) for moving the optical system wholly or in part, or for moving the screen, or for moving both, with respect to each other for focusing, and (2) for adjusting the inclination of the optical axis of the focusing-device with respect to the optical axis of the camera according to the distance of the object to be photographed. In the form shown in Fig. 1, the device comprises a lens 3 mounted in a sleeve 2 slidable on the horizontal limb of an angle tube 1 fitted with a prism 7 and a mirror (or prism) 8 which reflect the image formed by the lens on to a ground-glass screen 13 held in position in the vertical limb of the tube 1 against a spring 15 by a stirrup 11 mounted on a pin 10 passing through an aperture in a cylinder 20 journaled at 21 and 29, for rotation round an horizontal or a vertical axis respectively, to a base-plate secured to a fixed part of the camera. The pin 10 bears, inside the cylinder, against a wedge 23 on a plunger 19 journaled outside the cylinder at 25 in a. bracket 26 secured to the movable part of the camera, and coupled by a member 34, slidable in a slot 27 in the cylinder, to a nut 18 riding on a steep-pitched screw 16 having a fine-threaded forward part engaging a nut 17 carried by the sleeve 2. Thus, as the bracket 26 moves during the operation of focusing the camera, both the lens 3 and the screen 13 are displaced, and the operation is continued until the image is sharply defined on the screen 13, seen either directly, or in a mirror 5. The coupling 34 may be disconnected, and the sleeve 2 secured to the tube 1 by a catch 33; the screen 13 then alone moves during focusing. Wedges 23 of different pitch may be used for different camera objectives. A sleeve 30, rotatable but incapable of longitudinal movement on the cylinder 20, carries a pin 31 slidable in an inclined groove 28 in the fixed base-board, so that as the plunger 19 moves during focusing, the optic axis of the lens 3 is inclined with respect to the optic axis of the camera for sighting near objects. The apparatus may be turned through 90‹ about the journals 21, 25. A modification is shown in Figs. 5 and 6 in which a lens and prism system 50, 42 is carried by the fixed part of the camera, and a prism 43 with a ground-glass surface 44 by the movable part. The part 47 only of the surface 44 is ground to enable the apparatus to be used also as a range-finder.

Title: An improved control system for pneumatically operated electric circuit-breakers
IPC: H01H33/32
Filed: 1944-09-11
Abstract: 581,544. Actuation of switches. AKT.-GES. BROWN, BOVERI, & CIE. Sept. 11, 1944, No. 17320. Convention date, Sept. 11, 1943. [Class 38 (v)] [Also in Group XXIX] In a control system for a pneumaticallyoperated circuit-breaker, the control valves, both for switching-in and switching-out, are operated by power storage devices whose charging elements are actuated by the movable circuitbreaker contact. The control valves 4, 4<1> for supplying opening and closing air to cylinder 6 are pivoted to levers 7, 7' actuated by springs 9, 9<1> held stressed by toggle levers 8, 8<1>. The toggles are normally held set by catches 10, 10<1> and are reset by cams 11, 11<1> actuated through a shaft 12 and rod 13 by the movable blade 1. Release catches 14, 14<1> which normally engage catches 10, 10<1> are moved downward by combined push-buttons and electro-magnet cores 15, 15<1>. The button 15, a second release magnet 17, a no-volt coil 18, and an overload relay 19 are all attached to a common operating rod 20. A locking magnet 23, by lifting catch 14<1>, can prevent operation of the control system. To open the breaker, catch 14 deflects catch 10 which releases the toggle lever 8, and spring 9 pulls lever 7 to the left thereby opening valve 4. A rod 21 is also moved to the left, thus disengaging catches 14, 14<1> from catches 10, 10<1> and blocking any possibility of reclosing the breaker before it is fully open. When contact 1 is fully open, cam 11 resets toggle 8, and cam 11<1> frees toggle 8' ready for the next operation. The blocking rod 21 may also be moved by a piston 22 which operates if the pressure in container 3 becomes too low. A similar action takes place in closing.

Title: Improvements relating to diffraction gratings
Inventor: ENNOS ANTHONY EDWARD
IPC: G02B5/18
Filed: 1959-05-21
Abstract: 874,462. Diffraction gratings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 17, 1960 [May 21, 1959], No. 17344/59. Drawings to Specification. Class 97(1) A transmission phase diffraction grating comprises a plane parallel transparent plate having several parallel-sided strips of silicon dioxide on one surface, the thickness of the strips being such that the retardation of a ray of light travelling in a direction normal to the grating and passing through the plate and a strip is one half of a wave length of the light compared with the' ray of light passing normally through the plate only. This grating may be made by first coating a plane parallel glass plate with a layer of photosensitive resist such as bichromated glue or gelatin and photographically reproducing thereon the required diffraction grating pattern by exposure to ultra-violet or other exciting radiation, so that on subsequent development in an appropriate solvent a negative image of the grating in hardened resist material remains upon the surface of the plate. The plate is then mounted in a vacuum chamber and those portions of the glass plate which are not covered by the resist material are cleaned by a glow discharge. Oxygen is then fed into the vacuum chamber and silicon monoxide, contained in a tantalum foil capsule, is slowly vaporised within the chamber by passing a current through the foil. In this way a layer of silicon dioxide is deposited over the surface of the glass block and the layer of resist material. After removal of the glass plate from the vacuum chamber, it is rubbed with a pad soaked in hydrogen peroxide or nitric acid which removes the resist material and the overlying layer of silicon dioxide leaving the required strips of silicon dioxide on the glass plate to form the diffraction grating. Another method is described in which a silver layer is first coated on the glass plate and is then overcoated with a layer of photo-sensitive resist on which a master negative of the required grating is contact printed. A negative image in the resist material is then formed as in the first method whereupon the uncovered portions of the silver layer are etched away with an alcoholic ferric nitrate solution. The hardened resist material covering the remaining portions of the silver layer is then removed by soaking in a weak acetic acid followed by immersion in a trypsin suspension. The block is then cleaned by a glow discharge and coated with a layer of silicon dioxide by the vacuum process. Hydrogen peroxide or nitric acid is then used to remove the silver layer and the overlying silicon dioxide layer so as to leave only the silicon dioxide strips forming the diffraction grating. If desired, the. strips may be arranged in. a plurality of concentric circles so as to form a circular diffraction grating.

Abstract: 934,652. Parametrcalliy excited resonators. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 17, 1960 [May 29, 1959], No. 17420/60. Addition to 927,605. Class 40 (9). [Also in Group XIX] Parametrically excited resonators are combined to perform logical operations. An adder is described. A resonator, described in the parent Specification, is connected by transformers 34, 42, Fig. 1, to control circuits 38,46 which may be either input or output circuits. A resonator 48 and transformers 34, 42 are shown schematically in Fig. 4. The secondary windings 44 of four resonators A, B, C, D, Fig. 5, are connected in series in a closed loop. If, on simultaneous excitation of all the resonators, switch 50 is closed and one or two of the resonators are set in particular phases of oscillation by signals, the remaining resonators will automatically set so that two of the resonators oscillate in phase " 1 " and two in phase " O '. Thus with D field in " 1 " phase by a clock source S, the circuit performs a NEITHER NOR operation and gives an output on windings 36 of resonator C representing #A.#B. By interchanging the terminal of winding 36 the circuit will perform an INCLUSIVE OR function A+B. The circuit may be adapted to perform AB, #A#B, #A#B operations. Adder, Fig. 6. The secondary windings of transformers 42 individual to six resonators 48 are connected in a series closed loop P. Additional secondary windings 52, 54 of resonators E, F are connected in opposition in a loop Q to ensure that E.F always oscillate in the same phase which may be either " 1 " or " 0." Input and carry signals are applied to resonators A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>. The sum is derived from D<SP>1</SP> and the carry digit from F.
