Title: Improvements in control of tools and other movable parts in automatic lathes
IPC: B23Q5/26
Filed: 1956-10-12
Abstract: 843,397. Turning; drilling. SCHUTTE, A. H., COMMER, G., WELCKER, L., THEN, E., and PECHMANN, VON E. F., [trading as SCHUTTE, A. H. [Firm of].]. Oct. 12, 1956 [Oct. 15, 1955], No. 31180/56. Class 83 (3). [Also in Group XXIX] A machine-tool comprises a movable part 56, Fig. 4, controlled by cams, levers 18, &c., Fig. 1, through columns of pressure-oil 25, 26, between a control-piston 29, Fig. 2, and a working piston 53, the two columns working in opposition to one another and being connected to spring- loaded pistons 59. A lathe has a turret containing four work-spindles 11 having feed and work-holding collets operated by pistons 34, 33, respectively. Axially-traversed tool-slides 13, 14, and forming-tool-slides 15, 16, are operated by levers 18, 19, 22. Each lever, such as 18, is connected by a rod 32 to a piston 29 carrying rack-teeth engaging a pinion 31 meshing with a balancing-piston 30. The fluid displaced from and towards the oppositely-moving pistons passes along the lines 25, 26, to the pistons 33, 34. A similar transmission occurs between each lever 19 and a piston 38, Fig. 3, in a cylinder 35 for controlling the tool-slides 13, 14. The slide 14 carries a drill 47 rotated by a shaft 48, and is engaged by a nut 43 on the cylinder 35. Rotation of the nut enables the position of a depthstop 46 on the piston 38 to be adjusted. The depth-of-drilling can also be adjusted by rotating the piston 38, which is screw-threaded into the lathe framing. Attached to a further slide 56, which is the slide controlled according to the invention, is a piston-rod 54 adjustable against scales 57, 57a. When pressure-fluid is forced into the line 25 by a piston 29 (as in Fig. 2), the slide 56 is moved against a stop 62. There is then a slight over-travel of the piston 29, which moves a piston 59 a distance determined by the pressure of a spring 60 adjusted by a nut 61. If the slide 56 does not reach the stop 62 due to a blunt tool &c., the piston 59 is moved further to illuminate a warning light 53a and actuate a switch 96, to stop a part or the whole of the machine. The initial slight movement of the piston 59 takes up small fluid losses. If greater losses occur, the piston 59 moves sufficiently to allow a passage 67 therein to overlap a passage 66 to permit extra fluid to be supplied by a piston 64 engaged by a spring 65. If there is excess fluid, it passes out of the passage 67 into a duct 58a. A similar arrangement 58 is included in the line 26. Fluid may be supplied along a line 63c. If excessive losses occur in the system, the piston 64 actuates a switch 63a to stop the machine and illuminate a warning light 63b. Specification 843,396 is referred to.

Title: Braking systems
IPC: B60T13/66
Filed: 1972-07-04
Abstract: 1425452 Braking systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 8 June 1973 [4 July 1972] 31278/72 Heading F2F In a railway braking system having a fluid pressure operated brake and an electrodynamic brake the operation of a unit 2 interposed in the supply line to the fluid pressure brake is modified according to the degree of effectiveness of the electrodynamic brake. Selective energization of electromagnetic valves 107 of unit 2 results in pressure fluid being supplied from a conduit 108 via conduits 129, 130, 131 to the chambers 123, 124, 125 associated with valves 107 according to which of valves 107 are energized. A downward force thereby acts on a stack of diaphragms 119 which cause downward movement of a valve member 133 of a valve 134 whereby a further valve member 136 is separated from a seat 137. A chamber 141 is thereby communicated with a chamber 138 allowing pneumatic pressure to pass from a pressure source to chamber 138 via conduit 142 from whence it flows to the brake cylinder via conduit 140 and via conduits 139, 132 to a chamber 126 beneath the stack of diaphragms 119. Thus an upward force acts on the diaphragms to move valve 134 to a lapped position. If the electrodynamic brake is effective a signal dependent upon the degree of effectiveness thereof is applied via leads 58 to an electromagnetic coil 55 of an electropneumatic converter 1. Pressure normally passed via a conduit 104, input port 3, chamber 22, filter 18, choke 14 and chamber 12 to an exhaust port 5 is then passed via an outlet port 4 to a conduit 128 as a ball 32 is caused to throttle exhaust port 5 under the control of coil 55. The pressure in conduit 128 is communicated to a chamber 121 located between the upper diaphragm and the next lower diaphragm, which pressure results in a resultant upward force on the stack 119 since the upper diaphragm has a greater area than the next lower. Hence the output valve 134 is caused to be modified.

Abstract: 537,122. Acylated coumarone polymers. STEVENS, A. H. (Armour & Co.). Dec. 7, 1939. No. 31727. [Class 2 (iii)] [Also in Group III] The pour point of mineral oils and greases is depressed and the heat generated during running friction is decreased by the addition of an acylated coumarone polymer, the acyl group having at least 12 carbon atoms. The acyl derivatives are prepared by reacting coumarone or one of its polymers with a fatty acid chloride in the presence of an acylating catalyst such as aluminium chloride. An intermediate product which is a complexcontaining the catalyst is first produced which is hydrolysed to free it of catalyst. During acylation the coumarone polymerizes. Mixtures of two or more fatty acids may be used as acylating agents. Acid chlorides mentioned as suitable include lauryl, myristyl, palmityl, stearyl, oleyl, linoleyl and linolenyl chlorides. The reaction usually takes place in an inert solvent such as tetrachlorethane. In an examplestearyl chloride is added rapidly to a suspension of aluminium chloride in tetrachlorethane- Coumarone in tetrachlorethane is then added slowly, and the aluminium chloride complex is then decomposed with ice and the solvents steam distilled. The resinous residue is extracted with ether. Examples show the effect on various oils of adding the reaction product of (1) a partially polymerized coumarone resin and stearyl chloride. (2) coumarone and oleyl chloride. (3), (4) and (5) stearyl chloride and coumarone in varying proportions. (4) linolenyl chloride and coumarone.
