Title: Improvements in web feeding means
Inventor: MOON WILLIAM RICHARD HARDING
IPC: B41L47/24
Filed: 1950-10-02
Abstract: 704,077. Feeding webs. ADREMA, Ltd. Oct. 2, 1951 [Oct. 2, 1950], No. 24027/50. Class 100 (1) In a web-feeding mechanism, especially for attachment to an addressing machine or other series-printing machine, a roller 14 is driven continuously through a free-wheel 35 to feed a web from a storage reel to a loop at a lower average rate than it is withdrawn by an intermittently rotated roller 25, such that when the loop becomes taut the roller 14 overruns, thus permitting the roller 25 to draw the web directly from the storage reel. As shown, the main driving shaft 9 of an addressing machine drives a shaft 8 of the web-feeding mechanism by a chain 7, the shaft 8 driving the roller 14 through the free-wheel 35 on a shaft 34 driven through stepped pulleys 31 and 33 and a belt 32. The shaft 8 drives a disc 36 carrying an adjustably mounted crank pin coupled by a connecting rod 37 to a toothed sector 38. The sector 38 rotates the shaft 40 of the roller 25 intermittently through a pinion 39 and a roller clutch 41, reverse rotation of the shaft 40 being prevented by a roller clutch 42. The web is cut into sheets while stationary by a reciprocating blade 29 actuated by a cam disc 43 on the shaft 8. The web feeding mechanism may be mounted on a wheeled stand readily detachable from the machine feed.
Patent GB-252956-A (GB)
Title: Sheet glass drawing apparatus
IPC: C03B15/18
Filed: 1925-09-28
Abstract: 252,956. Golby, F. W., (Libbey-Owens Sheet Glass Co.). Sept. 28, 1925. Drawing.-Relates to sheet-drawing apparatus particularly of the Colburn type as des cribed in Specification 114,977, in which knurled rollers engage the edge of the sheet in the meniscus and prevent it from narrowing. According to the invention the rolls 21 are of such a diameter that they approximate to the normal curvature of the meniscus at the base of the sheets, and they are driven at a speed which is substantially the same as that of the adjacent mass of glass. The rolls 21 are watercooled and are formed with a slightly tapered knurled portion 23 and an incurved reduced end 24. This end is recessed or cupped. as at 25, to restrict cooling action on the sheet to the extreme edge portions and thus to keep the thickened bead 20 of relatively narrow width. Instead of being cupped, the ends 24 may be conical or torpedo shaped, and the inclination of the rollers to one another may be adjusted to produce a bead 20 of any desired shape. The sheet is thus formed with a thickened edge which retains sufficient heat to prevent breakage in the like while being stiff enough to hold the sheet at its full width.

Title: Safety apparatus for winding machines
Inventor: KLAESENER ARTHUR
IPC: B66D5/26
Filed: 1971-04-19
Abstract: 1293297 Winch brakes A KLASENER 19 April 1971 [17 March 1970 30 Oct 1970] 24135/71 Heading B8B A safety apparatus for winding machines comprises a remotely operated control valve 4 for compressed air, settable in one of two end positions by ropes 3, 5, the winding machine brake being locked once applied, when the valve 4 is in one position, and in the other position the brake is releasable. When the valve 4 is in its brake releasing position (shown) air flow through the valve 4 is prevented and the weighted brake 12 is controlled by an air ram 16 supplied from a line 19, through a changeover valve 17, a manual brake switch 20 and a minimum air pressure device 21. Upon opening the valve 4 (Fig. 2, not shown) compressed air flows from the supply line 1 to line 10, and once the brake has been manually operated, a valve 13 in line 10 is opened by a cam 11 on the brake lever and air passes from the line 10 to operate the changeover valve 17 causing an interruption in the supply line 19. The operated valve 17 permits line 19a to exhaust until a predetermined minimum air pressure is reached, whereupon the device 21 operates to block the line from the ram 16. Once valve 13 is opened, a pressure switch operated indicator lamp 18 is energized. To now release the brake, the valve 4 has to be closed whereby a piston 22 in the valve 17 is spring biased to return, connecting the pressure line 19 to the switch 20, and after manually resetting the minimum pressure device 21 the brake is manually releasable by the switch 20.
Patent GB-1063808-A (GB)
Title: Concentrated hop, and processes for its preparation
IPC: C12C3/04
Filed: 1964-06-10
Abstract: Concentrated hop is prepared by deep-cooling hops and subjecting them to the turbulent action of a gas vortex, so as to separate the various components of the hop.  Thus, the hops may be reduced in particle size to between 200 and 25,000 microns, cooled to a temperature within the range -1 DEG C. to -35 DEG C. and subjected to a vortex of air or carbon dioxide at a speed greater than 15 metres per second, up to 120 metres per second. The cooling of the hops is effected either in a refrigerator or by evaporating a low boiling-point material, for example liquid or solid carbon dioxide, liquid air, dry ice or liquid nitrogen. There may be employed for the size reduction a pulverizing machine employing a rotating flail which generates vortices by its rotation, a high speed cutting, percussion or jet mill, or a vortex-generating or vortex-supplied sifter, such as a centrifugal sifter equipped with a cylindrical sieve-casing provided with a rotating dish or beater, a bolting cloth or several opposing gas jets.  The hop concentrate is sifted in a rotation or vibration sifter or plan-sifter having a mesh width of from 175 to 500 microns to separate the lupulin-rich fine fraction from the lupulin-free coarse fraction.  The fine fraction is filled in an inert atmosphere into a light- and air-tight container from which the low boiling-point components of the fine fraction are eliminated by gradual evacuation.  The hops are coarsely defoliated prior to cooling.  According to an example, kilned hops are cooled to -30 DEG C. and reduced, in a high speed percussion mill supplied with air or inert gas vortices at about 50 metres per second, to a particle size of about 1000 microns.  The ground material thus obtained is separated at about -30 DEG C. by a vibration sieve with a mesh-width of 280 microns into a coarse fraction and a lupulin-containing fine fraction.  According to other examples (2) cooled hops are broken down by a jet mill supplied with air or inert gas vortices at about 100 metres per second and separated by a vibration sieve, and (3) hops are broken down in a reduction machine with a sieve perforation of 20 mm., are then cooled, and the cooled product is separated in a centrifugal sifter whose vortices are amplified by forcing gaseous carbon dioxide into the sifter.

Abstract: 728,082. Airguns. MARGADANT, J. W. Sept. 29, 1953 [Sept. 29, 1952], No. 24366/52. Class 119. In an airgun, the air pressure for discharging  the bullet is generated by two spring-operated pistons 5, 6, Fig. 1, acting in opposition to one another in a cylinder 3 having centrally disposed opening 4 leading to the gun barrel 1. Each piston has a retaining mechanism for holding it in the cocked position which comprises a spring- loaded catch 9, Fig. 2, which in the cocked position engages with a lug 10 on the end of the piston and is held in engagement by a pivoted trip lever 11. The trigger mechanism comprises a pair of tripper rods 12, 13, Figs. 1, 3, pivoted to the ends of a centrally pivoted lever 14, their free ends being arranged to bear against the trip levers 11. The rods 12, 13 are spring-urged to move outwardly but are held by the trigger 15 with an arm 18 engaging with the lever 14. On pressing the trigger 15, the lever 14 is released and the rods 12, 13 move outwardly against the levers 11 to release the catches 9. A safety mechanism which is automatically moved into locking position when the gun is cocked comprises a slidable catch member 17 which is moved under the arm 18 of the trigger to lock it by means of a leaf-spring 19 on the rod 13 when the latter is moved inwards during cocking. The gun is cocked by cocking levers which move slides to engage the pistons and move them against their springs so that each piston end 10 trips the catch 9 to move it in engagement therewith ; since however the outwardly-urged rods 12, 13 hold the trip levers 11 out of engagement with the catches 9, means, Fig. 7 (not shown), is provided to ensure the cocking of the trigger and hence inward movement of the rods 12, 13 away from the levers 11 before operation of the cocking levers. A dummy barrel containing a supply of bullets may be arranged over the rear part of the cylinder behind the barrel together with a bolt action type loader.

Filed: 1972-05-25
Abstract: 1367984 Making supported catalysts for IC engine exhaust systems; expanding metal GOULD Inc 25 May 1972 [2 June 1971 13 Dec 1971 (5) 31 March 1972 (5)] 24704/72 Headings B3A and B3W [Also in Division F1] A method of making a catalyst material which catalyses the reduction of NO x  in internal combustion engine exhaust gases comprises providing a metal foil, expanding the foil to provide an apertured foil and coating the surface of the foil with an adherent layer of catalyst material. The foil may be corrosion resistant or may be renderedcorrosion resistant either before or during the coating step. The foil, which is of Ni, Ni-Co, Ni-Fe or Ni-Fe-Co, is expanded by conventional apparatus. The expanded foil is electroplated with Cr, which is alloyed with the foil by heating at about 2200 F. for 2 hours at a pressure of about half an atmosphere in argon. Aluminium may be vapour deposited on the alloyed foil, with which it is in turn alloyed. The complete surface of the expanded foil is then electroplated with Ni, which is then diffusion bonded to it. Alternatively the Ni is overplated with Cu, Cu and Ni are co-deposited or particles of pre-alloyed Ni-Cu may be coated on the foil and sintered to form the catalytic coating. The step of expanding the foil may be carried out immediately before or after applying the catalytic coating. Further methods of making the catalyst comprise applying the catalytic coating directly on to Ni-Cr, Ni-Cr-Al, or Ni-Cr-Co foil, which is expanded either before or after the coating operation. Expanding the foil.-The foil sheet 20 is initially slit and stretched on the downward stroke of a knife blade 24, which is then moved upwardly and to one side half the length of a V-shaped strand 28 as the sheet is advanced on the machine bed 20. The knife movement is controlled by a ram 26, which is actuated by a conventional control mechanism.

Title: Combined process for the production of water enriched with deuterium and the synthesis of ammonia
IPC: C01C1/04
Filed: 1957-08-07
Abstract: <PICT:0870452/III/1> Heavy water is produced, in combination with the synthesis of ammonia, by passing the starting H2 in isotopic exchange with part of the ammonia produced therefrom, and working up the resulting deuterium-enriched ammonia into water.  H2O from 2 enters H2 generator 1, which may be an electrolyser, a water gas generator and/or CO conversion apparatus, or hydrocarbon decomposer.  The H2 passes to isotope exchanger 4 operating at 25 DEG C., and thence to ammonia synthesiser 6.  Part, e.g. 25%, of the ammonia, as liquid, passes back through 7 and may have potassium amide catalyst suspended therein before entering exchanger 4.  The D-enriched NH3 is withdrawn through 14, where catalyst is filtered out for recycling through 15, to catalytic combustion chamber 10 to form NO and D-enriched H2O, which may be passed to a dual temperature isotopic exchange concentration stage using hot and cold columns with H2 as exchange medium.  The deuterium-poor H2O may be returned to feed pipe 2. Alternatively, the NH3-H2 isotopic exchange may be in the gas phase, and the D-enriched NH3 may be subjected to isotopic exchange with H2O to produce the heavy water.

[Also in Group XXIV] An overload relief device for a shears having a freely swinging pendulum arm and a carriage movable in a carriage guide in that arm and carrying the upper knife is characterized by a slipping clutch between the driving motor and the pendulum arm and by means which, when an overload occurs, pivots said arm against a stop, releases one side of said guide carriage and allows the carriage to be deflected relative to the arm. The shears comprises a frame 1 and an eccentric shaft 3 driven by a motor through a slipping clutch (not shown). The pendulum arm 4 pivots about the axis of the shaft 3 and its movement is limited by a surface 5 engaging a stop 6. The upper knife 9 is mounted on a carriage 8 which reciprocates between guides 11 and 12 and is pivotally attached at 10 to a crank arm. The lower blade 7 is rigidly attached to the pendulum arm 4. The guide 12 is pivotally mounted at 13 and is normally connected to the arm 4 by a break-off bolt 14. If an overload occurs the arm 4 swings against the stop, the bolt 14 fractures and the carriage 8 is able to tilt by rotating the arm 12 about its pivot so that the upper knife 9 moves clear of the material 15. A spring may be used instead of the break-off bolt 14.
