IPC: B41F9/06
Filed: 1919-05-27
Abstract: 151,673. Mascord, G. W. May 27, 1919. Inking-apparatus for intaglio printing cylinders comprises a series of nozzles arranged under the cylinder and from which the ink is ejected at low pressure by a pump, or by gravity from a raised reservoir, surplus ink being collected in a fountain or trough beneath the cylinder. As shown in Fig. 1, the intaglio cylinder a is mounted above and within a trough or fountain b, and immediately below the cylinder is a nozzle member c connected by the supply pipe d to a low pressure delivery pump e supplied by a pipe f from a reservoir g. Surplus ink from the trough b is returned through a pipe h to the reservoir g. Strainers i, j may be provided in the trough band reservoir g. As shown in Fig. 2, the ink is supplied to the nozzles c through the pipe d by gravity from a reservoir g, the pump e being provided for returning surplus ink from the trough b to the reservoir g. The nozzle member c may be tubular and have nozzles formed therein bv flaring perforations, or have nozzles mounted upon it.

IPC: B64D17/52
Abstract: 133,979. Calthrop, E. R. July 24, 1918. Parachutes.-The rope 1 of the parachute is bifurcated, and the branches 3, 4 are led from the case 2 one up each side of the fuselage and detachably connected at their ends to a device 7 secured within the cockpit. When the aviator throws himself out on one side, the branch rope on that side takes his weight, and both branches are freed from the device 7. A rope 9 secured to the aviator's harness terminates in a dog-hook, the jaws 8 of which spring into recesses in the part 12 of the device 7. Eyes 6 at the ends of the ropes 3, 4 are frictionally held in such a position that, when the hook is pulled over to either side, it will snap into one of the eyes. Fragile cords 16 hold the eyes against accidental displacement, but break when the pull comes on the rope. Instead of providing recesses in the part 12, it may have spring members to retain the jaws of the hook in position.

Abstract: 611,643. Metal-melting furnaces. NEW JERSEY ZINC CO. May 2, 1946, No. 13405. Convention date, Dec. 21, 1945. [Class 51(ii)] [Also in Group II] Melting of metallic powders, particularly zinc, is facilitated by charging them from a hopper 14 into a furnace chamber B in which a rotor 16 flings up a shower of molten metal particles. A bath of molten metal is heated by the burner 7 in the chamber A separated from the chamber B by a pendant wall 5, said bath discharging molten metal into a casting trough 13. The rotor 16 made of graphite, silicon carbide or the like, is formed with pockets 24 and keyed to a hollow driving shaft 17 by an insulating cemeht sleeve 19, the shaft being liquid cooled. A non-oxidising gas such as carbon monoxide is fed to the chamber B and a sal-ammoniac flux may be used if the zinc powder is heavily oxidised.

Title: Improvements relating to vehicle lamps
IPC: F21V7/00
Filed: 1954-05-11
Abstract: 763,376. Vehicle reflectors. HINDS, R. P. H. April 26, 1955 [May 11, 1954], No. 13722/54. Class 75(2) A vehicle lamp comprises a rearwardly facing front reflector in the form of a surface of revolution about the principal axis of the lamp and disposed on the forward :side of a light source on that axis and a forwardly facing reflector having the same focal point as the front reflector and throwing forward in a parallel beam light received from the front reflector, either below the front reflector or through an aperture therein. As shown in Fig. 2, the front reflector 7 of parabolic form receives a parallel beam of light reflected from a parabolic mirror 1 whose focus is at the source 2 of light the mirror 7 redirecting the beam through its focus 8 to be again reflected at a parabolic or spherical concave or convex mirror 9 or 10 of short focal length relative to the focal length of the mirror 7 and disposed with its focus at the focus 3 of mirror 7 so that a parallel beam passes through a central aperture in the mirror 7. The central portion 6 of mirror 1 is non-reflecting. The upper half only of mirror 7 may be used, dispensing with the mirror 9, 10 and disposing mirror 1 with its focus coinciding with the focus of mirror 7 at the light source. Alternatively the semicircular parabolic mirror 9 directs the final beam beneath the semi-circular parabolic mirror 7. The front mirror 7 may be an ellipsoid 11, Fig. 3, with the light source 2 at the front focus of the ellipsoid and with the mirror 9 or 10 disposed with its focus at the rear focus 8 of the elliosoid, the final parallel beam being directed..through a central aperture in the front mirror 11. Alternatively the mirror 9 or 10 may be replaced by a plane mirror located on the minor axial plane of the ellipsoid, the final parallel beam being directed through an aperture in the plane mirror from a spherical mirror at the apex of the ellipsoid. In another alternative, two mirrors such as 7 and 9 or 10 may be disposed with the common focus at such point on the major axis of the ellipsoid as to direct the final parallel beam through the central aperture in the mirror 7, the central apical portion of the ellipsoidal mirror being then made non-reflecting.

Title: Improvements in sheet feed mechanism for ruling machines
IPC: B41G3/00
Filed: 1925-05-26
Abstract: 250,413. Reinhardt, E., (trading as Reinhardt, G. E.). May 26, 1925. Sheet-registering devices.-Sheets are fed to a ruling-machine under the control of rising and falling stops 1 which are raised when a sheet is to be fed. The rising of the stops 1 is effected by the action of abutments 2<1>, 3<1>, 2, 4 mounted on a cam disc or wheel 5, on a shoe 7 carried by a lever 6 which is connected to the shaft of the stops 1. In order to determine whether one, two, three or no sheets are fed to the ruling-machine for each revolution, the shoe 7 is laterally adjustable on pins 8 and is held in adjusted position by a spring catch 9. This shoe is set so that it is engaged by the abutment 4 alone, or by the abutments 4 and 3, or 4, 2, 2<1>, or by none of the abutments. This permits one, two, or three sheets to be fed per revolution of disc 5, or prevents feed altogether. The abutment 3 is formed with a reduced portion 3<1>, in order to permit the shoe 7 to engage the short abutments 2, 2<1> and the long one 4 without engaging the abutment 3.

Abstract: 1,197,857. Automatic exchange systems. SIEMENS A.G. 22 March, 1968 [23 March, 1967], No. 13908/68. Heading H4K. In telecommunication system including a plurality of programme controlled exchanges and in which connections to be effected between subscribers in different exchanges via at least one other exchange, are established section by section, each section being between an adjacent two of the exchanges, under subscriber dialling control, the dialling signals are divided into a plurality of groups of characters and only one group is initially fowarded from the originating exchange the other groups being retained at the originating exchange until demanded by another exchange over previously established sections. As described the dialling information comprises two groups of characters one group designating the wanted exchange and the other the wanted subscriber within that exchange. A hierarchical system in which the full designation of the wanted exchange is transmitted from an exchange to a superior exchange, and in which a shorter designation is transmitted from an exchange to a subordinate exchange is described. The shorter designation is derived from the full designation by eliminating those characters which designate only the subordinate exchange.

[Also in Group XXIX] The tubes or members of a heat exchanger are cleaned while the device is in action by means of a number of movable, water discharge pipes extending across the gas space above the tubes, each pipe producing a stream of water which can be traversed over the surface of the tubes &c. As shown, water is sprayed across banks of horizontal tubes 1 by spray heads 12 each comprising a pipe 14 provided with nozzles 21 of hemispherical form with a narrow slit 22 : an opening 23 avoids choking by particles of scale &c. The pipes are oscillated from a rotary crank disc 26, 27 through rods 24, 25, the crank throw being adjustable. Water is supplied by pipes 9 connected to a main 7, a valve 10 in each pipe 9 permitting the nozzles to be operated in sequence. Each pipe 14 is mounted in a stuffing box and an end bearing and may readily be removed for replacement &c. The waste gases flow down over the pipes 1 to an outlet 5, baffles 4 confine the action of the water to the tubes and prevent water pockets, and a deflector 6 directs the effluent towards an outlet 3 at the bottom of a hopper 2. The temperature of the water may be regulated.
