Abstract: 153,619. Williams, F. E. June 12, 1919. Wood, treating with liquids.-For changing its natural colour, wood is treated in a bath with a boiling solution of copper sulphate and ferrous sulphate in substantially equal proportions, which causes a chemical reaction in the pigmentary cells, or albumen, and fibre or grain of the wood itself. A solution specified is :-1 lb. of sulphate of iron to 10 gals. of water and 1 lb. of copper sulphate to 40 gals. of water mixed together. Elm treated with this solution is coloured a neutral grey. The wood is placed in a tank a, Fig. 1, containing the solution which is boiled by passing steam into it by a pipe b having a control valve c. For more rapid treatment pressure is employed, the wood being placed in a cylinder a, Fig. 3, connected by pipes having valves e, f to a cylinder a<1> containing the solution. When valve e is opened, an air pressure of 60 lbs. is obtained in the cylinders a, a<1>. The valve e is then closed and valve f opened and an increased air pressure is applied in cylinder a', the air from the top of the cylinder a being at the same time gradually released, causing the liquor to pass from cylinder a<1> to cylinder a. When cylinder a is full, the air release, and valve f are closed, and the liquor is pumped through valve g to the cylinder a<1>.

Title: Improvements in the cooling of rotating bodies
IPC: F16H41/30
Filed: 1948-06-02
Abstract: 667,565. Cooling rotary engines; centrifugal fans. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. June 2, 1948. [June 11, 1947] .No. 14867/48. Classes 110(i) and 110(ii). [Also in Group XXIX] A rotating body, for example, an hydraulic power transmission device, requiring to be cooled, is provided with plurality of annular external cooling fins and intervening grooves, an outer housing shrouding the grooves and interrupted at circumferentially spaced zones and elements mounted to have relative rotation with respect to the fins and projecting into the grooves at the zones of interruption of the housing so as to cause a controlled flow of air or gaseous medium which enters the grooves at one zone of interruption and is removed therefrom by a projecting element at another zone of interruption. A rotary casing 10 comprises members 40, 44 and 46, the member 40 carrying pump blades 18. Turbine blades 24, 26 are carried by a shaft 20 and reaction blades 30 by a member 32 fixed to a stationary housing 34. The member 44 carries cooling fins 46 separated by annular grooves 48. In order to obtain a high relative velocity between the air contained in the grooves and the fins, vane members 70 carrying vanes 72 which project into the grooves are provided. As shown in Fig. 2, there are six vane members spaced around the coupling so that each groove is divided into six parts. With the coupling rotating in the direction of the arrow 80 the air enters by inlets 73 and leaves by outlets 76 Although six vane members are shown a different number could be used and in some cases there could be only one inlet and one outlet. The internal surface 50 of the member 44 is cylindrical and radially spaced from a similar outer surface 52 on the member 42. Between these surfaces a cylindrical baffle plate or drum 54 is located to provide annular channels 56, 58. A series of bores 62 connect the outer part of the chamber 16 of the torque converter with the channel 56, and the channel 58 communicates with the chamber 16 through bores 64 at a place radially inward of the bores 62. The working liquid thus circulates through the bores and passages 62, 56, 58. 64 in the order named. The invention is applicable to torque converters having any desired number of stages or to couplings. The rotating casing may carry the turbine blades. The cooling circuit 62, 56, 58, 64 can be dispensed with, particularly in the case of couplings. Instead of the fins being as shown an integral part of the member 44, they may be attached to it by welding, or if the member is of steel and the fins of weaker metal of high thermal conductivity such as aluminium, they can be attached by the methods illustrated in Figs. 3c and 3d. The fins may be disposed as shown in Fig. 4. It is stated that the fins could be shrunk on to the member 44.

Abstract: 496,393. Turning-gear. C.A.V.-BOSCH, Ltd., and GLASER, W. H. May 29, 1937, No. 14979. [Class 7 (v)] In an engine starter in which the axial movement of a pinion e into mesh with an engine gear q is effected by an electromagnet h which also actuates a switch controlling the supply of current to the starting motor, a rod a arranged between the armature b and the outer casing c of the motor is connected at its ends to the pinion and to the movable part of the electromagnet. As shown, the rod is connected to the pinion by a lever d pivoted on the casing c and engaging a collar e<1> on the pinion, which slides on a sleeve f driven from the armature shaft g. The plunger i of the electromagnet h carries a lateral arm j acting upon the rod a through a thrust piece l and a rubber or other resilient member m in a sleeve k secured to the rod. A member o on the sleeve k normally separates contacts p in the circuit of the starting motor. On closing a pushbutton switch, current is supplied to the electromagnet h and to the motor through a resistance. The movement of the plunger j brings the pinion e into mesh with the engine gear q and allows the contacts p to engage, cutting out the resistance from the motor circuit.

Title: Improvements in or relating to the manufacture of nuts or the like
IPC: B21K1/64
Filed: 1934-05-22
Abstract: 438,725. Forging nuts &c. STEVENS, A. H., 5, Quality Court, Chancery Lane, London. -(National Machinery Co. ; Tiffin, Ohio, U.S.A.) May 22, 1934, No. 15254. [Class 83 (iv)] In making nuts &c. by a cold working process, a blank is upset into the confines of a die by forcing a piercing tool axially thereinto for at least half the length of the pierced blank while the surface at which the tool enters is unconfined, so that excess metal may flow axially around the tool, the surface of the hole is freed from the tool, and a punch forced axially through the blank to form an opening therethrough. One end face of the nut is then finished and the nut reduced to the desired axial length by end pressure which forces surplus metal into the opening out of which it is subsequently punched. A blank a, Fig. 4, previously shaped to present a flat bottom and chamfered upper face, is supported in an hexagonal die 18 by a ring 19 adapted to form an annular recess d, Fig. 7, on the blank when a pointed plunger 25 connected by a conical shoulder to a tool 24 pierces the top of the blank for rather more than half the depth thereof, excess metal forming a wave e about the conical shoulder. A second tool 31 then pierces the blank from the bottom while the top is supported by a recessed tool 29 adapted to flatten out the wave e and provide space for the reception of excess metal which may also flow into the cavity c formed by the plunger 25. These two operations force the material of the blank first to fill the lower corners of the die and then the centres of the side faces at their upper edges. The wad j is then punched away. In the form shown in Fig. 8, the blank is not previously chamfered and is supported in the die 110 by an hexagonal tool 112 having on its upper surface a projection 116. A plunger 111 similar to the plunger 25 pierces the blank forcing the metal down towards the lower corners and piling it upwards to form a chamfer e<1>. The blank is then shaped in a closed die, excess metal flowing into the recess g<1>, and the wad punched out. The closed die may be replaced by a plunger having a recessed end co-operating with a die such as 18, Fig. 4, excess metal flowing outwards between the plunger and die, or by hollow plungers which compress it axially, the lower plunger accommodating a punch for removing the wad.

Patent GB-153932-A (GB)
Abstract: 153,932. Comparri Wireless Control Syndicate, and Compare, M. June 17, 1919. Thermal relays.-A hot wire is so arranged in a local circuit that it can maintain automatic chattering at a musical frequency of a contact in the circuit, and received oscillations passing over the wire either cause or vary the chattering effect. A fine wire A, preferably of platinum 0.1 millimetre thick, is fixed at one end to a spring C, passes over a pulley B, and is attached at the other end to a lever D carrying a contact F which presses against an adjustable fixed contact G. A local circuit containing a telephone is connected in series with these contacts through terminals L, M, and the local current heats the wire A, causing it to sag. The lever D is then attracted by the magnet K so as to break the circuit at F, G, when the wire A cools and restores contact. The lever D thus executes maintained vibrations, the frequency of which is tuned by adjusting the screw H and contact G. Received oscillations are passed over the wire A through terminals M, N, and interfere with the vibrations of the lever D by heating the wire. They can, therefore, be detected by the telephone in the local circuit. In a modification, the wire A passes over a roller at each end, and the contacts are located at the middle of the wire. The moving contact then consists of a thin iron sleeve or a small iron spiral on the wire. In a further modification, the wire is vertically arranged, and gravity control is substituted for that. of the magnet K.
