Abstract: 619,229. Determining physical qualities and dimensions of materials; resistance measurements. NATIONAL RESEARCH CORPORATION. May 21, 1946, No. 15390. Convention date, May 22, 1945. [Class 37] A pressure gauge comprises an ambient temperature source of ionizing agent activity positioned to radiate ionizing agents through a fixed volume of a gas, the pressure of which is to be measured, to ionize the gas, an ion collector for the ions produced by the radiation, and electrical measuring apparatus responsive to the rate of ion collection at the collector for continuously determining the pressure, in a range of pressures, of the gas. As shown, the gauge includes a vacuum-tight cylindrical chamber 10 adapted to be coupled by a connection 12 to a vacuum system or other source of gas or vapour, the pressure of which is to be measured, and an inner shield 16 on the interior of which a radio-active substance 14 such as radium is mounted. An ion collector 18 having four prongs extends into the chamber through an insulator 20. The shield 16 is positively charged. The ionization current is passed into a circuit including a D.C. amplifier 25 and a meter or recorder 30. The radio-active equilibrium of the radium with its immediate decay products is preserved by depositing radium, as from a radium bromide solution, on to a metallic foil and sealing it by a film of rhodium, gold, nickel, or aluminium. The method of calculating the basic data for gauges required to meet specific requirements is set forth in the Specification. It is stated that the gauge could be used as a barometer or an altimeter.

Title: Improvements in or relating to the manufacture of film-type resistors
Inventor: WADA MITSUO
IPC: B41M1/06
Filed: 1967-04-04
Abstract: 1,132,794. Rotary presses; special inks. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 4 April, 1967, No. 15407/67. Headings B6B and B6C. [Also in Division H1] A method of manufacturing film-type resistors on flat phenolic resin laminate sheets comprises passing said sheets through a rotary offset printing press using conductive ink. A suitable ink comprises carbon powder, graphite powder and/or a metallic powder as the resistance material and an organic binding agent such as a phenolic resin or an epoxy resin in an appropriate volatile solvent such as benzyl alcohol, tetraline or triethyleneglycol. Another appropriate ink is a vitreous enamel resistor ink comprising a silver or palladium powder together with a glass frit and an organic binding agent in a volatile solvent. A further example of ink comprises an organic binder and an organo-metallic compound such as nickel formate or nickel oxalate either of which is converted into a nickel film when suitably heated.. The rotary press 4 shown, comprises printing, offset and impression cylinders 19, 18, 20 respectively, and a forme roller 11 inked by an automatically controlled motor driven inking train 12, 13. The press is fed by a feed device 2 through a registration device 3. The wet freshly printed sheets are passed through a surface treatment device 3 comprising a pair of pressure rollers. Subsequently the sheets are passed through an infra-red heated oven 8 on pallets placed on a conveyer 7. The electrical resistance of the finished resistors is then measured in an inspection device 14 which is electrically connected to an automatic resistance controller 16. The latter is connected to adjust a variable reduction gear 23 through which an electric motor 22 drives the inking train 12, 13. When any deviation of the value of the resistors from their predetermined value is detected by the device 14 an electric signal from the controller 16 adjusts the gear 23 to produce an appropriate change in the rate of ink feed. Sheet feed.-The feed device 2 comprises two sheet feed stacks 50, one on each side of a belt conveyer 54. A carrier 55 is positioned above each stack 50 and may be moved by a pneumatic cylinder 62 between a position above the stack to a position above the conveyer 54. Each carrier 55 has two vertically movable suction nozzles 64, the movement of the latter being effected by a pneumatic cylinder 66. Automatically actuated valve means control the pneumatic cylinders to effect the transport of a sheet from a stack 50 to the belt 54. The removal of successive sheets from the top of a stack lowers the top level. Through detector means a screw 70 is automatically actuated to raise the stack until it is exhausted. When exhausted further detector means automatically ensure feed from the other stack 50 and lowering of the exhausted stack for sheet replenishment.

Title: Gas fuelled lighter with concealed operating mechanism
IPC: F23Q2/16
Filed: 1969-03-26
Abstract: 1,200,046. Gas fuelled lighters. SOC. FRANCO-HISPANO-AMERICAINE FRANCISPAM. 26 March, 1969 [29 March, 1968], No. 15699/69. Heading F4F. A gas-fuelled lighter has a cap 2 secured to a body 1 by a hinge of the general construction described and illustrated in Specification 1,164,083, which is invisible when the cap is closed, and when the cap is opened a valve lever 12 is caused to pivot to allow gas to issue while simultaneously a driver 72 carrying a flint wheel 73 moves until it projects slightly beyond the side of the lighter body 1, ready for manual rotation against a flint 66. The hinge comprises guide rollers 21 on a block 5 within the body engaged in curved grooves 20 in a block 19 on the cap, and links 23 are each pivoted at one end 24 to the block 19 and have a roller 29 on a spindle 25 at the other end running in slots 28 in the block 5. When the cap is opened the limbs 23 initially move against torsion springs 34, 35 to a dead-centre position with the rollers 29 occupying end portions 28a of slots 28, and the spring 34 then urges the cap completely open. The spindle 25 also carries one end of a link 26 having a spindle 18 at its other end engaged in a slot 57 in a sector 58 pivoted on a spindle 40 which also carries the spring 35 and is secured in the block 5. The sector 58 has a toothed end part 58c, constituted by part of a cylinder having its main longitudinal axis coincident with that of spindle 40, which engages a pinion 60 connected to a rotatable driver-carrier 51 extending through block 5. A driver 72 holding a flint 73 is mounted on the carrier by a pin 63 offset from the rotational axis of the carrier so that, when the cap is opened, the link 26 rotates, turning sector 58 and pinion 60, and causes the carrier to move until it projects slightly beyond the side of the lighter body 1, ready for manual rotation against a flint 66. Simultaneously a roller 17 on the spindle 18 engages a spring-biased lever 12 pivoted on the block 5 and causes its forked end 12a to engage the head 11 of a gas burner-valve assembly 11, 10, 8 so that gas passes through a hole 52 in block 5 and is ignited by sparks guided thereto by a channel depression in the carrier 51. It is also possible to employ the pivoting movement of the driver carrier to turn the flint wheel relative to the flint and to provide a ratchet to prevent rotation of the flint wheel on return of the carrier. A single screw, Fig. 8 (not shown) holds in position a removable base-plate of the body, and a removable fuel reservoir, and abuts against one end of a spring urging the flint into contact with the flint wheel. The valve lever 12 has a curved portion 12b, which engages the roller 17 when the reservoir and the attached valve 8 are removed from the body.

Title: Improvements in or relating to low temperature carbonization of caking coal
IPC: C10B49/08
Filed: 1953-06-08
Abstract: 757,083. Carbonizing coal. PITTSBURGH CONSOLIDATION COAL CO. May 25, 1954 [June 8, 1953], No. 15754/53. Class 55(1). In a process of carbonizing a coking bituminous coal at a temperature between 800‹ and 1400‹F. the coal is pre-oxidized in particulate form by a gas containing free oxygen under non- agglomerating conditions within the plastic range of the coal, i.e. between 700‹ and 800‹F., and preferably between 750‹-790‹F., until the coal is rendered substantially non-agglomerative when heated to the carbonizing temperature. The process is preferably carried out using the fluidized solids technique but it may be carried out with the coal particles suspended in a gas as a dilute phase. As shown in Fig. 1, coal of fluidizable size is fed from a hopper 10 through line 18 entrained in a stream of recycle gas introduced at 16 into a fluidized preheater 20 which is externally heated and wherein the temperature of the coal is raised to 100‹-650‹F. The preheated solids and-gas overflow into a pipe 22 and pass into a fluidized pre-oxidation zone 26, preheated air being introduced at about 200‹F. into the bottom of the zone. Partial combustion raises the temperature to between 715‹ and 800‹F. and after residence in the zone for between 10-40 minutes the preoxidized coal passes by overflow 28 into a fluidized carbonization zone 32, additional heat being supplied for the carbonization by introducing at 34 hot recycle gas or steam at a temperature of 1200‹-1800‹F. Carbonization is completed at 800‹-1400‹F. in 1-1¢ hours. Coke is withdrawn at 38 and the gases leave by line 42 and pass into a condenser 44 where tar is recovered. In a modification the gases and tar evolved in the pre-oxidation zone may be collected separately from those evolved in the carbonization zone. The preheating of the coal may be carried out by means of hot gases or the preheating may be omitted and any additional heat required in the pre-oxidation zone may be supplied by recycling hot coke from the carbon izing zone or by partial combustion in the preoxidation zone. The heat required for the carbonization may also be supplied by partial combustion or by recycling hot coke from a separate coke combustion zone.
