Title: Improvements in or relating to machines for coating metal plates with tin and other metals or alloys
IPC: C23C2/00
Filed: 1934-04-03
Abstract: 436,007. Coating with metals. DAVIES ALEXANDER ENGINEERING WORKS, Ltd., S., and DAVIES, S., Baglan Road, Briton Ferry, Glamorgan. April 3, 1934, No. 10085. [Class 82 (ii)] A machine for coating metal plates with tin, terne, or other metal or alloy includes a grease pot in which is mounted a plate-wiping roll and also a brush-like wiper which holds the plates against the roll and wipes the opposite face of the plates to that acted on by the roll. The wiper also serves to wipe the roll when the plate has passed and to prevent buckling of the plates. The wiping roll preferably rotates at. a greater peripheral speed than the forwarding or finishing rolls between which it is located and it rotates in the same direction as the corresponding forwarding or finishing rolls. Two or more sets of wiping devices each comprising a wiping roll and a brush wiper are preferably provided in the grease pot, arranged so that each face of the plates is operated on by a wiping roll. The brush wiper, which may be a pad, e.g. of asbestos fibre, or may consist of a metal plate, is preferably weighted or spring- pressed to press the plates against the roll. The machine comprises a coating pot b with the usual feed rolls e and coating rolls h, one of the rolls of each pair being mounted in adjustable bearings, flux box i, guide m, and grease pot a. The grease pot contains three sets of forwarding or finishing rolls, o, 7, and 11, and two wiping devices each comprising a wiping roll and an associated brush wiper. All the rolls &c. in the grease pot are mounted in bearings formed in plates p, one on each side of the grease pot, so that the rolls and wiping devices may be removed as a whole. One of the rolls of each of the pairs o, 7, and 11 is preferably mounted in adjustable bearings in slots in the plates p, the adjustable roll being pressed against the fixed roll by means of a lever pivoted to the plate p and adjustable at its upper ends by means of counterweights or springs x. Above the rolls o is a wiping device comprising a wiping roll y, which may be mounted in adjustable bearings and is preferably of greater diameter and driven at a greater speed than the rolls o, and a brush 1 of asbestos fibre held between plates 2 which are pivotally mounted in brackets 3 and may be weighted or spring- pressed to cause the brush to press on the roll y. Above this wiping device is another similar device comprising a roll 4 and brush 5 arranged so that the roll acts on the opposite face of the plates to that wiped by the roll y. The rolls are preferably all driven from a shaft 17, the rolls e, h, o, 7, and 11 being all driven at the same speed and the wiping rolls y and 4 at a greater speed to enhance the wiping effect. The wiping rolls remove surplus metal and scruff. If desired, one or both of the pairs of rolls 7 and 11 may revolve in a small bath of molten metal to increase the thickness of the coating.

Title: Improvements in Mine Signalling Apparatus.
Inventor: MILLIGAN JOHN
IPC: B66B19/06
Filed: 1917-07-13
Abstract: 111,642. Milligan, J. July 13, 1917. Mine and colliery signals.-In step-by-step apparatus for mine signalling having three pointers, the ratchet-wheels operating the pointers are moved by a loose ratchet-wheel directly controlled by the signal impulses and returning to its original position after a pause determined by a dash-pot or equivalent. The arrangement is such that the pointers are moved simultaneously to the number signalled, and, at some signals, only one pointer remains to register the signal, the others returning to zero, but two pointers remain to register the other signal or signals. A loose wheel i is moved one step at each signal impulse during the return movement of a sliding member f<1>, operated by the usual signalling cord, by a pivoted pawl f<2>. The wheel i is retained by a detent o, normally held out of engagement by a chain n connected to a weighted lever l. The lever l is moved on the first signal impulse by a pin l<4> engaged by a pin f<0> on the member f<1> so that the detent o comes into operation. Return of the lever is delayed by a dash-pot or equivalent m, so that the detent o is again disengaged when sufficient interval has elapsed after completing a signal. The pointers b, c, d are respectively secured to the spindle c and coaxial sleeves f, g on the spindle, and are operated through corresponding wheels h, j, k. The wheel i has projections i<1>, i<2> engaging corresponding projections on the wheels h, j. The wheel k is driven through similar connexion from the wheel j. Each wheel h, j is provided with pins to one of which a weighted cord is secured, the other pins forming the equivalent of a drum on which the cord winds as the wheel is rotated. These weighted cords return the pointers b, c to zero. The wheel k and pointer d are returned by a spring r. The wheels h, j, k are retained, when the wheel i returns by detents pivoted at t, but are so mutilated that they are only retained at certain predetermined signals. As described, the wheel j, and with it the pointers c, d, remain to register " three " the wheel k and pointer d alone remain to register "six," and the other signals are registered by the pointer b alone. The first impulse of a signal cancels the previous signal by means of a pin f<5> on the member f<1> raising a pivoted bar y, a pin y<1> on which raises the detents. Signals are cancelled when being complied with by a sliding rod x, the upturned end of which engages the lower ends of the detents. The rod v is operated by suitable connexions from a pivoted rod raised by a finger on the spindle of the usual depth-indicator, and maintained raised as long as the cage occupies intermediate positions in the shaft. By this arrangement signals given when, for example, the cage is being used in repairing the shaft, are only registered until the dash-pot m allows the detent o to be disengaged.

Title: Improvements in ships and vessels of all kinds and sizes adapted to travel upon water and in means for propelling the same
IPC: B63B1/38
Filed: 1920-04-12
Abstract: 167,810. Clay, H., April 12, 1920. Lubricating. - Ships are constructed of shallower draught forward than aft and with one or more storage chambers beneath the bottom adapted to accumulate air under pressure and lift the vessel bodily under the water, the air being supplied by the propelling or other means and confined at the forward end by an adjustable plate. A ship with forwardly projecting bow 3, Fig. 1, has depending centre and side plates 9 forming with the concave bottom channels. In front of the centre channel is placed a partly immersed propeller 1. The propeller is encircled by a semicylindrical casing 11 and draws air in at the forward end from which it is passed to the channels beneath the bottom. The front of each side channel is closed by an adjustable shoot or plate 20 when the vessel is moving ahead, whilst the plates are raised when the direction of the vessel is reversed. When the propeller is completely enclosed its casing rotates with it, and a joint is made with the fixed after casing; the casing for the screw may also carry a second exterior worm screw. In a modification, Fig. 15, two screws 32, 33 extend the length of two semicylindrical casings 30 and 31. When an ordinary aft screw is used, air is induced when the ship is under way through a channel 37, Fig. 19, and the channel may have a cowl fittins 38, Fig. 22. With an aerial propeller drive the slip stream may be diverted beneath the plate or a specially driven air pump can be employed. In a further modification, wind driven vanes 61, Fig. 26, drive a shaft 51 carrying scoops 49. 50 which force air down the central chamber and thence beneath the bottom of the boat.

Abstract: 1346615 Compressed air braking systems KNORR-BREMSE GmbH 20 April 1971 [20 April 1970] 10253/71 Heading F2F In a compressed air brake system for a rail vehicle a pressure control valve 25 provides a quick release of the vehicle brakes after a brake application by introducing a pressure surge into the train pipe 2. Brake application.-A drivers valve 20 is moved to allow pressure in a pipe 22 connected to a reservoir 21 to pass to atmosphere. The pressure in a chamber 13 of a relay valve 1 is thereby lowered enabling the pressure existing in a chamber 11, connected through an orifice 17 of a wall 10 separating the chamber from a further chamber 3, to move a piston 12 rightwardly causing air to pass through a tubular piston-rod 14 to atmosphere. Pressure in a train pipe 2 connected to chamber 3 is thereby lowered to apply the brakes. Thereafter as the pressure in chamber 11 falls piston 12 is caused to move leftwardly allowing a valve seat 15 thereto to rest against a valve plate 7. Brake release.-The release valve 25 has a piston 26 separating upper and lower spaces 24, 28 connected respectively through a pipe 19 to a pressure reducing valve 18 and to the reservoir 21. Plunger 35 is manually depressed and the difference in pressure between the spaces 24, 28 is sufficient to allow piston 26 to remain in a lowered position, abutting stops 42, in which space 28 is connected to a chamber 31 and pipe 22 by way of a passage 40 in a slide 37. Chamber 33 is connected by way of a pipe 34 to the chamber 11 of valve 1 and by way of a passage 41 in slide 37 to atmosphere. Chamber 11 is thereby vented and piston 12 moves leftwardly lifting valve plate 7 to connect train pipe 2 to a reservoir pipe 4 to charge the train pipe. The charging period is limited by the cross-section of a nozzle 27 in piston 26 which causes pressure in space 24 to be gradually lowered to that in space 28 so that piston 26 and valve slide move upwardly to cut off chamber 33, and hence chamber 11 from atmosphere. Air pressure then tends to equalize between chambers 11, 3 through throttle 17 and piston 12 moves rightwardly to seat valve plate 7.
