Title: Improvements in or relating to printing-machines for printing on frangible articles
IPC: B41F1/06
Filed: 1927-03-05
Abstract: 269,495. O'Hara, S. April 17, 1926, [Convention date]. Offset machines; intaglio-plate printing.-A machine for printing impressions from an intaglio steel die or plate on frangible articles, in which impressions from the die are printed on a resilient offset printing-surface covered with gelatine and are transferred therefrom to the frangible article mounted on a work support, is constructed with a plurality of printing-surfaces which are simultaneously operated so as to bring one surface into contact with an inked die and another surface which has already been printed on into contact with the article to be printed. As shown, two printing-surfaces 16 are mounted on a stem 14 carried by a plunger 12 reciprocated in a guide in a frame 10 by an eccentric 15. The stem 14 is formed with diametrically opposite notches 18 with bevel faces engaged by spring-pressed pins 19 which cause the pads 17 to register respectively with an adjustable workholder 36, and an intaglio die 26 all carried by a reciprocating slide operated by a rack and pinion 27, 28 to move the die under inkng and wiping devices 30, 32, to ink and wipe the die between successive descents of the printing-surfaces. After each printing operation the operator moves the stem 14 through half a revolution by pressing on one of the arms 15 as a lever, and the rotation is stopped when the pins 19 engage the notches 18.

Title: Pneumatic All Speed Governor
IPC: G05D13/00
Filed: 1968-02-08
Abstract: 1,156,297. Gas turbine engine fuel systems. BENDIX CORP. Feb. 8, 1968 [March 8, 1967], No. 6322/68. Heading F1G. [Also in Division G3] An all-speed governor 46 having constant droop or gain for a gas turbine engine receives compressor discharge pressure (C.D.P.) at 56 and this pressure, which is a function of engine speed, can act via restrictors 196, 188 on opposite sides of diaphragm 168. The region downstream of restrictor 188 is vented through restrictor 194 so that the pressure difference across the diaphragm 168 is a function of C.D.P. and thus of engine speed. The force due to this pressure difference acts on lever 102 via stem 154, lever 104 and spring 108, and opposes tension spring 122 connected to arm 130. The latter is fast with an arm 136 co-operating with a cam 128 connected to control lever 52. A third arm 142 acts as a stop to define the idling speed. Lever 102 includes a flapper 146 which co-operates with nozzle 148 to produce a control pressure in line 78 which is applied to the outside of bellows 64. The inside of bellows 64 responds to C.D.P. in chamber 60 and this bellows is connected to an evacuated bellows 66 in chamber 60. Both bellows are connected through a torque tube 86 with a fuel metering valve 82. Chamber 60 is vented through restriction 208 and receives C.D.P. through a first restrictor 198, adjusted in response to ambient temperature variations as detected by discs 202, and a second restrictor 74. In operation, clockwise rotation of lever 52 to select say, maximum speed, causes counterclockwise rotation of arm 130 and lever 102, the movement of the latter causing pin 118 to abut rod 112 to eliminate the effect of spring 108. Flapper 146 increases the control pressure in line 78 to compress bellows 64 to increase fuel flow. As the speed increases, C.D.P. in chamber 60 increases and compresses bellows 66 to further increase fuel flow. At maximum speed, the pressure differences overcomes spring 122 and flapper 146 is positioned to maintain the speed constant. Needle 186 co-operates with restrictor 188 to vary the gain of the governor.

Title: Improvements relating to blades of air-foil configuration
IPC: B29C70/86
Filed: 1955-03-03
Abstract: 775,816. Helicopter rotor blades; screw propellers. WARNKEN, E. P. March 3, 1955 [March 3, 1954], No. 6382/55. Classes 4 and 114. [Also in Groups V and XXVI] An aerofoil blade, for example an aircraft propeller blade or a helicopter rotor blade, comprises a core of pro-stressed, substantially straight, resinbonded glass fibres extending substantially the length of the blade, and a root portion at one end of the blade. The glass fibres are preferably in the form of elongated rovings but they may be in the form of glass fibre fabric. The method of making a compressor blade in accordance with the invention is shown in Figs. 3 and 19. Lengths of resin-impregnated glass fibres 16 are folded double and a pin 17 is inserted through the fold, the fibres then being placed in the lower mould portion 18. The free or blade tip ends of the fibres are clamped at 19 and the fibres are stressed when the upper mould portion 26 is pressed downwardly causing the ends of the pin 17 to slide along the inclined grooves 22, 23. A plug 24<SP>1</SP> of resin-impregnated glass fibres is inserted in the space above the pin 17. While pressure is applied to the mould by the ram 26<SP>1</SP> the pre-stressed fibres are heated to cause curing of the resin, and the resin when cured holds the fibres in pre-stressed condition and forms a hard, smooth, infusible blade surface, The resin may be a phenol formaldehyde type or may be a suitable epoxy resin. In a second embodiment, the fibres are folded round a pin member as shown in Figs. 9 and 10, the pin member having a portion 41 of tear-drop shape and rib portions 42, 43, 44. The fibres and the pin are mounted in a mould as shown in Fig. 11, the fibres being pre-stressed by a clamp device 52. A moulding compound comprising resin and short staple glass fibres (about half-an-inch in length) is introduced into the mould through a gate 53 under a pressure of about 2¢ tons per square inch. Preferably both the elongated fibres and the short staple fibres are resin-coated or -impregnated. While under pressure, the blade is heated to set the resin and form a hard infusible blade mass. Another type of pin member is shown in Fig. 15, the resin-impregnated glass fibres being folded around a pin portion 66, the fibres and pin then being inserted in a mould as shown in Fig. 16. The fibres are pre-stressed by means of a clamp 78 attached to the free ends of the fibres and resin-impregnated short fibre glass staples are then injected into the mould.

Title: Improvements in and connected with Interlocking Mechanism for Combined Electric Switches and Plugs & Socket Connectors.
Inventor: MIDDLETON VICTOR GEORGE
IPC: H01R13/707
Filed: 1918-03-27
Abstract: 124,703. Middleton, V. G., and Baker, C. J. March 27, 1918. Plug couplings combined with electric switches. In an interlocked quick-action switch and plug- and-socket connector in which the switch-member and the operating-member have independent movement, the lock is operated independently bv the final movement to the closed position of both the operating-handle and the contact brushes, so that the plug cannot be removed until both the operating-handle and the switch-member have been moved from the closed position. As shown in Fig. 2, the operating-spindle 13 carries an elliptical cam 28 and the relatively movable brushes 14 carry a similar cam 29 slightly smaller than the first. These cams both bear upon rollers 30, 31 mounted at the upper end of a spring-urged plunger 32, the lower end of which passes through a partition 2 in the switch casing, and, in the closed position of the switch, the plunger is depressed to engage a slot 34 in the plug casing. When both the switch handle and the brushes have been moved to the ' off ' position, the cams permit the plunger to rise and unlock the plug. Specification 124,577 is referred to.

Title: Fountain pen
IPC: B43K5/18
Filed: 1945-03-15
Abstract: 594,321. Reservoir pens. PARKER PEN CO. March 15, 1945, No. 6531. Convention date, April 10, 1944. [Class 146 (iii)] In a fountain pen having ink-feeding mechanism and a rib housed in a one-piece shell that encloses the nib so that only the extreme point is exposed, the shell, nib and ink feeding devices including the reservoir are formed as a unit which is detachable from the pen barrel. The feed member 12 is of elongated form with a longitudinal eccentric hole 22 to receive a hollow cylindrical shank 15b on the nib 15. A spring 28 presses the nib outwardly, the movement being limited by the engagement of the flared inner end 15c of the shank 15b with the similarly-shaped end of the hole 22. The shell 13 which is a close fit on the member 12 and abuts against a rib 20 thereon, has a reduced inner end which is engaged frictionally or by threading within the end of the barrel 10, so that the parts 12, 13, 15 can be removed as a unit from the barrel. An ink sac 16 is attached to the inner end of the member 12 so that it forms part of the unit. Circumferential capillary grooves 25 increasing in width towards the pen point are formed in the member 12 and are intersected by a longitudinal groove 26 in communication with the ink reservoir and of lesser width than the grooves 25. An air channel 27 also intersecting the grooves 25 is formed on the lower face of the member 12. When the pen is filled, ink fills the shank 15b and passages 25, 26, 27. During subsequent use, the nib first takes ink from the passages 25 by capillary action thus freeing the air passage 27 whereupon ink flows normally from the reservoir 16 through the tube 15b and passage 26. The passages 25 also serve to absorb any overflow, thus closing the air passage, until the ink in these passages has been used.

Filed: 1963-02-19
Abstract: A method of cooling hot rod in which the hot rod is passed continuously through a duct, through which particulate material in a fluidized state is also passed. In the embodiment described steel rod of carbon content 0.40%-0.85% is cooled to produce a fine pearlitic structure.  The rod 12 is passed into the duct 14 via a guide tube 13, through which fluidized particulate material is also passed, causing a transfer of heat from the rod 12 to the duct 14.  The duct is cooled by passing liquid nitrogen via a pipe 33 into a pipe 15, formed about the duct 14, from whence it passes through the expansion chamber 34 and pipe 35 to the compressor 25. Particulate material such as sand passes from a hopper 22 into the pipe 23, where it is fluidized by nitrogen supplied under pressure by an ejector pump 24 from the compressor 25, and passes through the duct 14 and into the particle collector 18.  From there the particles are returned to the hopper 22 via the pipe 30 and cyclone separator 31, by means of nitrogen supplied under pressure from a secon ejector pump 27, the nitrogen leaving the circuit via a discharge pipe 32.  A heat transfer rate of 300-475 BTU/ft2/minute may be achieved. <PICT:1036894/C6-C7/1>

[Class 82 (i)] A process of reducing oxidized ores of zinc, sodium, &c. having reduction temperatures in excess of their boiling-points consists in introducing a charge of finely-divided ore into a retort, maintained at the reducing temperature, and withdrawing the mixed metallic vapour and gases through a heated coke filter to a condenser. A preferably preheated mixture of finely-divided ore, e.g. roasted zinc sulphide, and coke or charcoal is fed from a heat-insulated hopper 18 into a retort 14 disposed in a furnace heated by burners 40, and the vapour and gases from which pass through louvred openings 24 into a coke filter 15, in which carbon dioxide is reduced to carbon monoxide, and thence to a condenser 27. The metal is run off through a spout 28, while the carbon monoxide passes to a reservoir 30 from which it is supplied by a blower 34 to the lower end of the retort. A part of the carbon monoxide may be passed through a pipe coil in the furnace flue to assist in atomizing the charge entering the retort. Methane may be employed as the reducing gas.

Title: Improvements in or relating to dischargers for pyrotechnic devices
Inventor: SCHERMULY ALFRED JAMES
IPC: F42B5/15
Filed: 1956-03-05
Abstract: 823,391. Pyrotechnic devices. SCHERMULY PISTOL ROCKET APPARATUS Ltd. June 4, 1957 [March 5, 1956], No. 6790/56. Class 9(2) A discharger for pyrotechnic devices has a cylindrical metal barrel 1 cannelured at one end about a metal plug 2 into the centre of which is screwed a member 9 secured e.g. by brazing, to one end of a rectangular section rod 10 helically twisted along its length. An annular recess 4 in the inner surface of the plug houses an ejecting charge 5, the recess being connected by flash passages 7 to an electric igniter 6 mounted at the centre of the outer surface of the plug. Housed in the barrel is pyrotechnic device comprising a circular plate 11 of synthetic resin, with a central aperture 12 of similar cross-seetion to the rod 10, which extends through the opening 12 with a loose fit into a tube 13 integral with the plate. A washer 14, having a loose fit in the barrel and around the rod 10, separates the plate from the charge 5. The annular space around the tube 13 is packed with strips 16 of metal foil held in the barrel by is waterproof closure 17. Several of the dischargers may be fired simultaneously by placing them in sockets 19 provided on a base 18, Fig. 5, and connecting the igniters 6 to a common source of electricity. The plate 18 is of electrically insulating material and houses a spring-loaded plunger 22 at the centre of each socket, which abuts an insulated contact 24 of the igniter 6. A plunger 20 housed in the socket 19 is pressed into electric contact with a recess 3 in the barrel 1 by a spring 21, so that when a potential difference is applied to the plungers, there is a discharge through a primer charge 27. The plunger 20 also serves to hold the discharges in the socket. On ignition of the charge 5, the washer 14 and plate 11 are driven out of the barrel with a gyratory motion caused by the inter-action of the rod 10, and tube 13. The centrifugal force produced scatters the strips 16 outwards. The rod 10 may be of square, triangular, elliptical or other non-circular section. Flare candles or smoke canisters may replace the metal foil.
