Patent GB-646742-A (GB)
Title: Process for dyeing or printing superpolyamide fibres
IPC: D06P3/24
Filed: 1948-03-30
Abstract: Nylon fibres are dyed or printed by applying a water-soluble dyestuff containing acid groups together with a salt of a volatile base with a less volatile acid and/or a heat-decomposable ester of an acid, as an agent capable of liberating acid when heated, and then steaming the fibres.  The dye may be an acid wool dye or a direct cotton dye, and examples of suitable substances liberating acid when heated are ammonium oxalate, ammonium thiocyanate and ammonium tartrate. Solution promoters such as urea, phenol and resorcinol may be present.  In examples: (1) nylon fabric is printed or padded with a composition containing one of several specified dyes, ammonium tartrate, resorcinol, gum and a mixture of oleic acid and pine oil neutralized with potassium hydroxide, and steamed; (2) the ammonium tartrate of (1) is replaced by ammonium thiocyanate, and (3) nylon is padded with a solution containing the dyestuff, resorcinol, gum, wetting agent as in (1) and ammonium tartrate, and then steamed. Specification 624,457 is referred to.

Title: Improvements in or relating to electrical water heaters
IPC: F24H7/04
Filed: 1941-07-16
Abstract: 550,697. Electric water heaters; actuation of switches. McDOWELL, O. A., and DONE, J. P. C. July 16, 1941, Nos. 9009/41 and 7033/42. [Class 39 (iii)] [Also in Groups XIII and XXXVII] Water is heated by passing through passages in or around a heat storage block, and is further heated by immersion or other heaters in flowing through a heating chamber to the outlet. Two containers 22, 24, Fig. 2, have water spaces 26 in their upper parts, and metal, masses 28 in their lower parts with headers 30 and passages 32 considerably smaller than the spaces 26. Water passes through from inlet 34 to outlet 38. The containers may be provided with heat insulation 41,'43. Flat resistance heaters 48 are placed between the blocks, and 50, 52 between the chambers 26. Heater 48 may have three coils in parallel, and heaters 50, 52 may each have two similar coils in parallel. Alternatively, the heaters may be placed in passages 32 and spaces 26. Inlet passage 36 is provided with a regulating valve 54, and is connected through valvecontrolled passages 57 with a chamber 58 having a diaphragm 56 which actuates a switch controlling the heaters. The rod 86 is arranged adjacent to three parallel blades 70, 72, 74. When no water is flowing, heaters 50, 52 are inoperative and heater 48 is energized to heat the storage blocks until cut out by a thermal switch 98. When the water supply is turned on the switch contacts are closed in succession to energize relays 76, 78 which energize the heaters 52, 50. Energizing of the second relay ,78 also opens the circuit of the heater 48 at contact 96, which is thus inoperative when water is flowing through the heater. In a modification, Fig. 6, a vertical tank 106 is provided in its lower part with a metal block 104 attached to one wall and heated by a flat heating element 114. Two immersion heaters 122, 124 are arranged in the water space 108 and are controlled by a mercury switch actuated by a diaphragm similar to 56, Fig. 3, without relays. The circuit includes a thermal switch controlling the heater 114, which heats the storage block 104 and water behind it, the elements 122, 124 being inoperative. When water is turned on, hot water is discharged and the pressure-operated diaphragm actuates the mercury switch to place first the heater 122 and then both heaters 122, 124 in circuit and to cut out the heater 1114. Instead of employing a heat storage block, heat may be stored in a liquid, or in a fuzible solid such as naphthalene or bismuth alloy. Specification 527,511 is referred to.

Filed: 1964-03-06
Abstract: 1,099,561. Photographic processing apparatus. W.W. BUECHNER. March 9, 1965 [March 6, 1964], No. 9566/64. Heading G2A. Apparatus for carrying out successive treatments on photographic material comprises a housing divided by vertical walls into a series of compartments into which treatment vessels can be removably inserted, the vessels and the compartments forming between them liquid-tight seals so as to define vertical up-and-down paths for a stream of heated water which flows through the apparatus to maintain a constant temperature therein. Fig. 12 shows a basic construction, the housing being divided into a series of compartments by vertical walls 405 - 415. Into these are placed treatment vessels 430 - 440, which contain the various processing solutions or washing water. The treatment vessels may be of disposable plastic materials or plastic-coated paper. A steady flow of heated water is passed through the apparatus to maintain a constant temperature therein. Fig. 12 shows the water inlet at the lower left of the housing, the water then being heated by electrical elements 481 - 484, and the water outlet at the upper right of the housing. On its passage through the apparatus the water flows continually in an up-and-down path between the walls of the vessels and the compartments, these walls fitting together in various sealing arrangements so as to define the said path. Instead of being of rectangular section, the compartments and the vessels may be of circular section. Many variants of wall and vessel shapes, sealing arrangements, and other details are illustrated, together with supporting arrangements for the photographic sheets, and details of automatic agitating and sheet-forwarding mechanisms.

Title: Improvements connected with press guards
IPC: F16P3/04
Filed: 1944-05-22
Abstract: 582,468. Machinery safety devices. PRESS GUARDS, Ltd., and EVANS, F. A. May 22, 1944, No. 9810. [Class 80 (iv)] Relates to guards and safety devices particularly for power driven screw-operated presses in which the guard is interconnected with the drive mechanism so as to render the press inoperable so long as the guard is open and consists in providing means whereby should the ram move downwards under power with the guard open, the drive of the operating screw will be reversed to retain the ram in its raised position. The ram 3 has a projection 4 adapted to be engaged by a scotch, in the form of a hook 5, pivotally mounted at 6 on a block 7 carried by a link 8 of the clutch operating gear. It is also pivotally connected, by an adjustable link 13, to a lever 9 secured to a spindle 10 journalled in side members 11 of the guard and on which a gate 12 is secured. A lever 14 also secured to spindle 10 is connected by a link 15 to a lower gate 16. When the gates 12, 16 are closed, the scotch 5 is withdrawn from the projection 4 to permit the starting lever 17 to be moved to move the shaft 25 axially, through link 8, lever 20 and linkages 21-24 to bring the wheel 26 into engagement with disc 27 on the screw 28 and lower the ram. During this operation the projection 4 is bearing against the edge 29 of the scotch and therefore the gates 12, 16 cannot be opened during descent of the ram. Should the ram move downwards under power, with the gates open, the link 8 would be forced down to move the shaft 25 to bring wheel 30 against disc 27 and cause the ram to rise. Should the ram start to descend when the drive is disconnected, the wheel 30 will be brought against the disc 27 to act as a brake therefor. Specification 555,746 is referred to.

Abstract: 992,491. Trailers for lifting and transporting trees. C. J. NEWMAN. March 14, 1962, No. 9834/62. Headings B8B and B8H. A trailer for lifting and transporting a tree to be transplanted comprises a frame 11 mounted on two wheels 22 and supporting an inclined pillar 26 on which a clamp for engaging the tree trunk is adjustably mounted. The clamp comprises sections 36, 37 interconnected by a hinge-pin 38 and a removable pin 39 and rotatably supporting on a roller bearing 41 two semi-cylindrical members 44, 45. The member 44 is formed with grooves to engage a rope wound around the tree trunk and the member 45 is provided with a boss 51 for a screw having a trunk-engaging plate 54. The section 36 is pivoted to a sleeve 32 on the pillar 26. In operation, the trailer is tipped so that the clamp may be engaged around the base of the trunk and ropes around the root-ball are connected to hooks, Fig. 5 (not shown), mounted on the clamp. The wheels of the trailer are then chocked and the winch of the towing vehicle is then actuated to draw in a cable 56, which passes over a pulley 57 and is secured to an eye on the clamp, to return the trailer to the position shown in Fig. 3, thereby lifting the tree and positioning the root-ball 17 on a support 15 on the trailer frame. In a modification, Fig, 10 (not shown), means are provided for adjusting the position of the clamp on the pillar 26.
