Class 146(3) A pencil or like sharpener comprises a rotatable cylindrical cutter 5 carried by a spindle 5<SP>1</SP> which is rotatably mounted on a rotatable shalft 3, a gear wheel 6 fixed to said spindle being engaged by a fixed gear 7, a device 9 carried by the shaft 3 for adjusting the length of point to be given to the pencil, said device being movable in relation to the shaft and having a lug 10 which deflects shavings so that they do not enter the gears, the shaft having a radial projection 17 cooperating with the housing 1 to convey the shavings away. The shaft 3 is mounted in the housing 1 and is driven by a handcrank 4, at the opposite end to which is a recess 20 to accommodate the pencil to be sharpened; when the crank 4 is turned the gear wheel and cutter are rotated and the pencil sharpened. The projection 17 rotates with the shaft 3 and sweeps the pencil shavings through an aperture 18 into a collecting box (not shown) below. The device 9 for adjusting the length of point is slidably mounted on a flattened portion 21 of the shaft 3 and is retained there by a coil spring 14 which passes round the shaft 3, through a hole 22 in the projection 17 and is attached by its ends to studs 15, 16 on the device. The pencil lead engages an abutment 11 on device 9. A bent-over rear portion 13 of the device engages an annular groove 12 in an adjusting screw 8 mounted in the shaft 3 and which may be manually rotated to vary the distance of the abutment 11 from the apex of the recess 20. The lug 10 on the device is parallel to and to one side of the end face of the cutter adjacent to the gearing.

Title: Improvements in reversible hydraulic couplings
IPC: F16H61/52
Filed: 1946-03-27
Abstract: 609,974. Hydraulic couplings. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. March 27, 1946, No. 9435. Convention date, March 27, 1945. [Class 69 (ii)] In a hydraulic coupling sets of displaceable blades are placed between the pump and turbine blade rings, so arranged that when these are in the fluid circuit the coupling is reversed. The reversing blades 10, 11 are mounted for radial movement, but are kept out of action by centrifugal force on the blade weights when the blade carrier is running freely. When this carrier is braked, spring 14 overcomes the reduced centrifugal force and the reversing blades move radially into action. In a modified form, the outer ring of blades only are movable.

Title: A process for the production of water gas and like synthesis gases
IPC: C10J3/00
Filed: 1942-07-09
Abstract: 578,332. Water gas generation. STEINSCHLAEGER, M. July 9, 1942, No. 9571. Addition to 577,015. [Class 55 (i)] In the intermittent production of carburetted water gas, heat is supplied to the generator partly by using a regenerator heated by the blow gases or by gases from another source, and partly by blowing with air, a mixture of water gas and steam and/or carbon dioxide being then passed through the regenerator to the water gas generator and oil introduced into the gases produced in the geneiator so that the oil is cracked by sensible heat of the gases produced and of the undecomposed steam and/or carbon dioxide. In a modification, synthesis gases (H and CO) are obtained by passing through the regenerator hydrocarbons and steam and/or carbon dioxide before their supply to the generator which is blown from time to time, the sensible heat of the gases produced being stored in the ash bed and used for superheating the steam or gases used in subsequent gas making and blowing periods, sufficient steam and/or carbon dioxide being supplied to the regenerator to effect reaction with the hydrocarbons in the regenerator and provide an excess for the water gas reaction in the generator. The generator 1, Fig. 2, is blown upwards by air, and the hot gases generated passed through the superheater 2 and regenerator 3. During the run, re-cycle gases are supplied by line 7 and steam through line 8 to the regenerator 3 and injected into the generator 1, a part of the gases leaving the generator being re-cycled as above, and a part passing by line 11 to where oil is injected at 12 and the mixture passed through the superheater 2 by line 13, the oil being cracked to yield carburetted water gas. Coke oven gas or other methane containing gases such as residual gases from oil synthesis processes (together with steam or carbon dioxide) may be used to replace the re-cycled gases. When making synthesis gases, after the blow in which the regenerator 15, Fig. 4, is heated, steam and/or carbon dioxide is admitted by line 20 and hydrocarbon gases by line 21, the resulting products containing CO and H passing by line 17 through the generator 14 when further H and CO are produced by the steam and/or carbon dioxide remaining, the final gases being taken off by lines 22, 23.

Title: Improvements in or relating to fin-stabilized projectiles
IPC: F42B12/80
Filed: 1959-03-19
Abstract: A fin-stabilized projectile for a smooth bored mortar or rifled gun is coated with a synthetic resin base lacquer containing a finely pulverized salt, which at the moment of firing is decomposed, thereby absorbing heat and creating a protective surface boundary layer of steam.  The salt may be ammonium oxalate, suitable lacquers being based on a phenolic resin, wood oil and stand oil.  A further, heat reflecting layer, containing titanium dioxide, may be applied.

Title: Improvements in and relating to thermocouple apparatus for identifying metals
IPC: G01N27/00
Filed: 1944-05-19
Abstract: 578,569. Testing physical qualities ; current meters. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1944, No. 9646. Convention date, May 21, 1943. [Class 37] A device for testing and discriminating between metals comprises a D.C. measuring instrument having terminals in the form of rods of known metallic material extending from the instrument and adapted to have their pointed ends pressed into contact at spaced points with the metal material to be tested to form a continuous circuit through the test material and the instrument, means being provided for heating the pointed end of one of the rods so that the contact between the pointed end and the material under test becomes the hot junction of a thermocouple in the instrument circuit. Fig. 1 shows a test piece 18 contacted by iron prod terminals 14, 15 of a D.C. motor 10 the moving coil 13 of which is connected directly across the terminals. The prod 15 has a removable heating coil 19 near its tip fed from a source 20 and may be provided with a sleeve 22 having cooling fins 23 to avoid excess conduction of heat to the instrument. The prods are removably held by thumbnut clamps 16, 17 so that prods having different thermocouple characteristics may be used depending upon the materials to be tested. The direction and magnitude of the meter deflection is a measure of the thermocouple voltage due to the hot junction 15, 18 and may be used to identify metals under test. The meter may be of the centre-zero type but this is not essential as the heating prod may be connected to the thumbnut 16 or 17. To vary the spacing of the prod-point contacts one of the prods may be bent and rotatively adjusted. For the rapid testing and identification of metal bars the prods and handle of the instrument may form a pair of tongs. In this case the handle comprises a part 28, Fig. 2, fixed to the meter casing and a co-operating portion 27 forming an extension of the prod 25 pivoted to the meter casing at 26. The prod ends are inturned to grip the material 30 under test and a switch 32 mounted on the instrument case controls the heater coil 19. The prod 25 may be a permanent part of the pivoted handle structure but is preferably removable as in Fig. 1.
