Patent GB-190716236-A (GB)
Title: Improvements in the Manufacture of Plates for Printing in more than One Colour and in the Method and Apparatus for Colour Printing.
Inventor: HILDYARD GEORGE RICHARD
Filed: 1907-07-15
Granted: 1908-07-15
Abstract: 16,236. Hildyard, G. R. July 15. Overlays and make-ready arrangements. - In a process for printing in more than one colour, all the colours are printed in succession from one plate with the tones in relief by means of separate make-readies each having the parts in relief for printing its own colour. On the plate, which may be of zinc, the solids are first drawn in absoluteresist ink, and, after covering the plate with semiresist varnish, it is etched in dilute nitric acid so that the solids are left in relief. After being washed and dried, the nearest solid parts are painted with the absolute resist, semi-resist varnish again applied, and the etching repeated. This process is repeated until the lightest tones have been produced. The plate may also be prepared by a photographic process. A gelatine film on the plate is exposed under the negative just long enough to transfer the solids, when the soluble gelatine is dissolved and washed off, and the plate etched, the same process being repeated for all the successive tones. To get heavier tones, the plate may be painted at the required parts with a varnish or the like, such as gold size containing a little colouring-matter. A separate make-ready is prepared for each colour to be printed. The makeready is attached resiliently to the impression surface. The impression cylinder a has a suitable blanket b secured to one end of a sheet of flexible cardboard c, the other end of which is glued to a strip of stiff linen d, having elastic loops e attached to hooks on the cylinder axle. Cardboard layers c', c" are then used to build up the surface. To prepare the make-readies, the plate is covered with the first colour to be printed, an impression taken on the make-ready, and the parts not required to be printed in this colour cut out or removed by the operator so as not to print at these parts. Where the colour is to be lighter, the make-ready is slightly depressed. By repeating the process with the other colours, separate make-readies for each colour are obtained, but, when light and dark colours of a similar nature are to be printed, one make-ready can be used for them, the light colour being first printed, and then the parts not to be in the dark colour removed, so that they do not print in the succeeding impression. In preparing each makeready, it is preferred to take a pull or impression of the whole plate on a sheet of paper right over an impression of the colour or colours so far completed, so that the operator may see which parts are to be removed.
Patent GB-190718761-A (GB)
Title: A Rotating Mercury Pump for Exhausting the Air or Gas from or Obtaining a Vacuum in Vessels
Inventor: MACKENZIE JAMES
Filed: 1907-08-20
Granted: 1908-05-07
Abstract: 18,761. Mackenzie, J. Aug. 20. Coiled-tube type.-A rotary mercury pump of the coiled-tube type, for exhausting electric incandescent lamps, tubes, or other vessels in which a high vacuum is necessary, comprises one or more pairs of helical tubes, one system of tubes forming a right-handed helix or helices and the other system a left - handed helix or helices. The tube a, Fig. 1, forming the right-handed helix is joined at one end to the left-handed helical tube b, and mercury in the lower portions of the tubes travels upon rotation of the pump about the horizontal axis of the coils away from and then back into a vessel d into which both tubes open. The imprisoned columns of air can only travel away from the end into which a tube c opens, because mercury always covers the end of the tube leading the column in the opposite direction when a valve f therein is opened by a camp, and at other times the valve is closed. The tube c leads to the vessel x to be evacuated, and is coiled so that upon rotation the tendency of any liquid is to pass out of this tube c. A blind tube m is provided to act as a mercury reservoir to supply mercury between the two conical glass stoppers h, i forming the valve f, while the valve is closed. Alternatively, the valve may be actuated electro-magnetically by coils q, r, s, t, Fig. 3, in each direction acting upon iron cores u, v in the conical valve portions, the circuits through the coils being completed by brush contacts on the axle of the pump at the correct points in each revolution ; or the coils q, s may be employed for actuation in one direction only with a gravity of air-pressure return. When the valve is operated electro-magnetically, the valve-rod l may be dispensed with, or may be modified for a gravity return. The tube c may be connected to an adjacent similar pump, or may be sealed on to the vessel to be evacuated, or may be connected through a liquid seal 2 to a fixed tube y provided with a liquid trap z and attached to the vessel x. A box 1 surrounds the connexion of the tubes c, y, and is itself surrounded by mercury or other liquid to prevent leakage of air into the exhausted vessel. The pump tubes may be formed of glass, steel, vulcanite, or other suitable material, and may be formed in one casting or block, and each convolution of the helices may be formed in any of the known geometrical figures. A supplementary pump is employed for the preliminary exhaustion, and the slight residue of air is exhausted by the rotary pump.

Title: Improvements in Apparatus for Delivering Measured Quantities of Liquids.
Inventor: BEAL SAMUEL
Filed: 1907-12-09
Granted: 1908-06-25
Abstract: 27,152. Beal, S. Dec. 9. Measured quantities, delivering.-In apparatus of the fixed measuring-vessel type, the valves for admission and discharge of the liquid are controlled by cams C, H, S upon a hand-operated shaft R. Liquid enters by an inlet pipe through the valve B and fills the vessel to the predetermined mark, the air in the vessel being compressed in a space F at the top, which communicates with a snifting-valve K by means of a pipe L and a number of holes 0 in the cap N. The handle G is then moved to open the valve K and thus vent the compressed air above the liquid. On further movement of the handle, the outlet valve P opens and the liquid flows out. In a modified arrangement, the inlet and outlet valves are manipulated by a single cam. If the liquid measured is not under pressure, the cap W may be replaced by a small tube open to atmosphere, and the snifting-valve K is not required.

Title: Improvements in Machines for Coating Paper or other Material.
Inventor: PIFER GEORGE NICHOLAS
Filed: 1907-12-31
Granted: 1908-10-29
Abstract: 28,756. Pifer, G. N. Dec. 31. Paper, coating.-In apparatus for coating paper or other materials, and especially for coating photographic paper or film, the web to be coated is passed through the coating-material without being in contact with any rollers or like guides. As shown in Fig. 1, the web x passes over a roller 4 and under two flanged disks 11, which rotate on a spindle 10, and then passes over a roller 5. The bend in the web between the two disks 11 forms a trough, the level of the liquid placed therein being kept below the points of contact between the web and the disks. The web may be kept in contact with the disks by means of endless bands 13, kept in tension by weights 14 and pulleys 15, or by other means ; or the weight of the disks and of the vertically-movable spindle 10 may be utilized for this purpose. Other drums 19 may be mounted on the spindle 10 and between the disks 11 to form separate troughs for coating the web in stripes. These drums may be heated if the coating- material is liquid only when hot, or the coating- material may be heated directly by a steam heating- arrangement 16, or heat may be applied through the web by a hot-water bath 17. Fixed guides may be substituted for the rollers 4, 5 and disks 11. If the web is to be coated on both sides, it hangs down between the drums 4, 5, the loop passing through the coating-material, and the ascending run of the web being long enough to permit the coating to dry before it reaches the drum 5.

Title: Improvements in Alternating Current Relays
Inventor: STRUBLE JACOB BAKER
Filed: 1908-02-11
Granted: 1908-08-27
Abstract: 3056. Struble, J. B. Feb. 18, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Switches.-In a railway-signalling relay which is actuated to close the local circuit or circuits by the highfrequency signalling-current only, and not by the low-frequency power current, the energizing-coil is wound on the middle leg of au E-shaped laminated electro-magnet. Around one of the other legs of the E-shaped magnet is wound a closed coil, and the counterflux due to this coil, when traversed by an alternating flux, reduces the number of magnetic lines passing through this leg and increases the number of lines passing through the other leg. The turning moment on the laminated armature, which is pivoted on the middle leg of the magnet, thus varies with the frequency of the energizing-current. When no current is flowing in the energizing-coil 2, the overbalance weight 5 on the armature 4 holds the armature in contact with the non-magnetic stop 9, and, when a low-frequency current flows in the coil, the greater magnetic resistance due to the longer air gap between the pole 8 and the armature, than between the pole 7 and the armature, more than compensates for the counter-flux in the leg 7, induced by the closed coil 6 which surrounds this leg, with the result that the pole 7 is still the stronger and the armature remains in contact with the stop 9. But, when the highfrequency signalling-current flows in the coil 2, the strength of the pole 7 is so greatly decreased by the increased counter-flux induced by the closed coil 6, that the pole 8 now becomes the stronger, and the armature 4 is attracted against the non- magnetic stop 10 in the pole-piece 8, and the rod 12 pivoted at a is moved to close the local circuit at 14. The relay and the source of signalling-current are directly connected across the rails, adjacent sections of which are connected by reactance bonds which act as impedances to the signalling-current and direct it through the relay coils.

Title: A New or Improved Pulley Block
Inventor: ELLIOTT JOHN DOUGLAS WHITCOMBE
Filed: 1908-03-21
Granted: 1908-12-03
Abstract: 6339. Elliott, J. D. W. March 21. Pulley-blocks.-In a pulley-block, the sheaves are carried in a disk fitted to revolve in a suspending- ring, flanges being provided either on the disk or on the ring to retain the parts in their proper relative positions, and openings being formed in the ring and disk which coincide in one position to allow the rope to be inserted. The ring a has a slot band two teeth c which engage with teeth f on the disk d, which together with its flange g forms the backplate. The disk and flange are slotted to receive the pulleys h, which run on a pin the ends of which are squared to enter slots t in the disk. A covering- plate m is slotted similarly to the disk, and has notches n for corresponding notches in the divisionplate k to take into. To assemble the block, the pulleys are placed in the plate shown in Fig. 5, the ring a is placed over the disk d, and the cover-plate m is attached as shown in Fig. 1. Holes u, v, w in the flange and disk are provided, through which a pin may be passed to convert the block into an ordinary fixed block. In order to pass the ropes over the pulleys, the disk is slid upwards so as to become disengaged from the ring a, and is then turned within the ring until the slots in both and in the plate m coincide.

Title: Improvements in Rick Shifting Vehicles.
Inventor: CALWELL WILLIAM
Filed: 1908-04-18
Granted: 1909-04-08
Abstract: 8654. Calwell, W. April 18. Loading road vehicles. A rick-shifting vehicle is provided with endless-chain gearing by means of which the rick is hauled on or off the vehicle or held securely in position. Two shafts c, d are mounted beneath the vehicle, the shaft c having a drum c<1> at each end, round which ropes or chains c<2> are passed, and the shaft d a central sprocketwheel gearing with a chain d<2>. The ropes c<2> pass over pulleys f<1> capable of sliding on short spindles f, and their ends are connected together after being passed round the rick by the device shown in Fig. 4 in which a hook h<1> on a link h engages with an eye g<1> in a link g ; the hook h' is disengaged by turning a lever g<2>. The chain d<2> passes over a guard-plate d<6> at the front of the platform and over a pulley d<5> at the rear, and is secured to the cross-bar b<2> of a cradle b running on rollers b<3> and provided with prongs b<1>, which are pressed into the ground when in the loading position. The shafts c, d carry loose sheaves c<3>, d<3>, the sheave c<3> being geared by a chain to a sheave d<4> secured to the sheave d<3>. Both sheaves are turned by a handle e connected to a sheave e<2>, which is geared to the sheave d<3>: When the handle e is turned clockwise, the sheave d<3> turns idly on its shaft but the sheave c<3> turns the shaft c by means of a pawl i<1> and ratchet-wheel, and the rick is drawn on'to the platform, dragging the cradle b with it. A pawl j<1> on the side of the vehicle engages a ratchet-wheel j on the shaft c and prevents backward motion of the winding-drums c<1>. When the handle e is turned counter-clockwise, the sheave c<3> turns idly, and the sheave d<3> drives the shaft d by means of a pawl k<1> engaging a ratchet-wheel k, and the cradle b is pulled backwards. If the fastening g, h has not been released, this backward movement secures the rick on the vehicle. The sprocketwheel engaging the chain d<2> may be replaced by a drum round which the chain is passed. A modification is described in which pulleys are provided at the rear of the platform round which the ropes c<3> can be passed and connected together in front of the rick so that the rick can be discharged by winding up the ropes c<2>. In a further modification, the ropes c<2> are wound on drums on the axle of the vehicles so that the rick is pulled off when the vehicle is moved forward. The rear of the platform may be curved downwards.

Granted: 1909-05-13
Abstract: 21,856. Smith, M. A. Oct. 15. Confectionery or sweetmeats.-A machine for coating candy centres &c. with chocolate comprises an endless series of carrier fingers for the centres, a hopper which supplies the chocolate, an oscillating air-blast for removing excess of coating, pneumatic means for marking the coated goods, and means for transferring the coated goods to plaques which are automatically fed to a conveyer. The centres are conveyed by a band 26 beneath guide-strips 27 to fingers 28 on a reciprocating bar 29. When the fingers 28 are withdrawn, the centres are left on vertical fingers 47 on shelves 46 pivoted on arms of a revolving shaft 44. The fingers 47 pass between horizontal fingers on a moving endless carrier, which passes over wheels 14 and under the fingers 28. During the further rotation of the shaft 44 the fingers 47 descend, leaving the centres on the carrier fingers, which carry them under a hopper 60 provided with a valve-controlled slot and supplied with chocolate by buckets 58 carried on endless chains 55 in a jacketed chocolate receptacle 2. The centres are alined before being coated by an oscillating bar 73 and a roller 123, which serves also to coat their under surfaces. The coated goods pass under an oscillating nozzle 161 supplied with an air-blast, which removes excess of coating- material, and then under a pneumatic marking- device 88 where they are removed from their supports by the sudden horizontal withdrawal of the fingers. The ends of marking tubes then descend on the coating, which is slightly raised by air suction in the tubes, and, during the removal of the tubes, air pressure is restored in them to prevent the coating-material from being removed. The coated and marked goods are received on plaques, which are periodically released from a magazine by cam action and are gripped by automatic means on conveyer chains 137.
