Title: Improvements in and relating to feed mechanism more especially for use or incorporation in a gear-finishing machine
IPC: B23F19/06
Filed: 1953-06-25
Abstract: 725,627. Gear - finishing. NATIONAL BROACH & MACHINE CO. June 25, 1953 [Sept. 8, 1952; April 27, 1953], No. 17636/53. Class 83(3). Feed mechanism for a machine-tool comprises powerdriven feeding means 64, adjustable abutment means 60 to limit each infeed operation of the feeding means and control means for alternately effecting successive adjustments of said abutment means and said feeding means. The mechanism, in a housing 40, may be applied to a shaft 32 to rotate, through worm gearing 28, a screw 27 connected to the vertically-fed table 24 of a gear-shaving machine. The shaft 32 carries a gear 42 meshing with a gear 44 attached to a block 46 carrying a roller 50 engaging a surface 52 on a lever 54. The lever 54 is pivoted at 56 and carries a roller 58 engaging a rotatable stepped cam 60. The shaft 32 is initially advanced by an air piston 65 which rotates the block 46, and hence the gear 42 and shaft 32, until movement of the lever 54 is arrested by engagement of the roller 58 with the cam 60. This moves a gear on the table 24 from a loading position to an initial shaving position. The initial retracted position of the gear is determined by a plate 144 which is adjusted against a scale 152 and carries a stud 146 to engage the pivot of the roller 50. The cam 60 is indexed by a pneumatic device 70, 71 through links 72, 73, 80, a pawl 78 and the index plate 82. At the end of its movement, a dog attached to the piston 71 actuates a valve 91 to operate the piston 65 again and thus advance the screw 27. The cam 60 is held in each position by the roller 58 engaging shoulders thereon, the lever being itself held owing to the non-reversible gearing 28 in the feed train. The piston 71 is reversed by a time-delay device and releases the valve 91. The final depth of cut may be adjusted by rotation of the shaft 32 after disengaging a fine-toothed clutch 134, the clutch being normally held engaged by a lever 114 having lobes 126 which can be moved away from a clutch-holding plate 128 by turning a rod 118 having a cam-groove 122. A push-button control may be provided for the piston 71. The machine may be fitted with an automatic loading device as in Specification 688,533.

Title: Means for lubricating bearings
IPC: F16H57/04
Filed: 1946-06-14
Abstract: 632,790. Bearings; lubricating. WILLYSOVERLAND MOTORS, Inc. June 14, 1946, No. 17891. Convention date, Aug. 14, 1945. [Class 12 (i)] [Also in Group XXIV] Lubrication of the bearing between a stationary shaft, supported in end walls, and a rotatable element journalled on the shaft, is effected from a reservoir recess formed on the outer surface of the shaft and supplied with lubricant from a passage in the end wall through an interposed thrust-bearing washer having a lubricant passageway. As applied to a variable-speed gear-box, the lay shaft 35, Fig. 1, is fixed and is recessed to form two lubricant reservoirs 61, 61<SP>1</SP>, supplying diagonal channels 59 to the bearing sleeves 56, Fig. 10, with which the bore of the gear cluster 33, 37, 38, 39 is fitted. The reservoir recesses consist of spaced surfaces 60, Fig. 9, of flattened curvature. The recess 61 is supplied through a recess 73, in a thrust-bearing 65 of laminated construction with bearing material and steel backing, Figs. 7, 8, held in place by a lip 70 bent to enter a lubricant channel 71 in the end wall 11 of the gear-box 10.

Patent GB-1363912-A (GB)
Title: Apparatus for laying filamentary material
IPC: E04G21/12
Filed: 1971-05-28
Abstract: 1363912 Winding strand around structures M J DYKMANS 28 May 1971 [16 July 1970] 17933/71 Heading B8G [Also in Division B3] Wire S is wound around a tube T under a controlled tension, means being provided for indicating the tension in the wire leaving a wire gripping drum 21, by moving a carriage 7 around the tube by the engagement of a chain C encircling the tube with a sprocket 22 mounted in the carriage on a shaft 10 driven by an hydraulic motor 30, and controlling the rotation of the wire gripping drum 21, To take up slack after the wire has been attached to the tube, the tap 102 of a resistance 103 is adjusted to provide an increased voltage to a servo control 97. This causes a control motor 92 to operate a pump 370 and increase the volume of delivery to a line 360A. A motor/pump 361 thus acts as a motor to rotate the drum 21, via sprockets and chain 15, 16, 16A, a shaft 40, and sprockets and chain 41, 42, 21B, to reel in the wire slack. At this stage a motor 360, fed by a line 360A and connected to the shaft 10, is stationary due to the friction of the carriage. The wire continues to be reeled in until the wire becomes stressed, the stress being monitored by a load cell 100 which supplies a proportionate voltage signal to the control 97 and a signal to a tension indicator, e.g. a visual or permanent type paper recorder. The control 97 compares the signals to the load cell and the tap 102 and when the two signals become equal, pressure is developed and maintained in the line 361A. The carriage 7 is ;hen moved by supplying fluid pressure to motor 30 which causes the shaft 10 to rotate the sprocket 22. When the carriage moves, the drum 21 rotates and acts as a prime mover to operate the motor/pump 361 as a pump. The pump 361 pumps fluid in line 361A to the motor 360, the latter also driving the shaft 10. Assuming that during the carriage movement there is a decrease in the preset tension of the wire, the decrease is sensed by the transducer 100 which cause pump 370, via motor 92, to deliver a greater fluid pressure to the line 360A and so automatically restoring the wire tension. The pitch of the wire is controlled by two limit switches LS1 and LS2. When switch LS1 is opened by a stationary cam 242, a counter having a preset count is actuated and hydraulic fluid is supplied to a motor 206 of a winch 202. A platform 5 is moved vertically within the carriage 7 by rotation of the winch so that the wire is layed on the tube at an angle to the horizontal. The rotation of the winch rotates a cam 222 which actuates the switch LS2 which is connected to the counter. When the preset count is reached the motor 206 is stopped and the wire is layed horizontally on the tube.

Title: Improvements in the production of nitrogen-containing polymers
Inventor: FISHER JAMES WOTHERSPOON
IPC: C08G73/08
Filed: 1949-07-07
Abstract: Linear polymers resistant to acid hydrolysis and containing the 1,2,4-triazole nucleus repeated along the polymer chain are made by heating a dicarboxylic acid and two moles of hydrazine for each mole of acid in the presence of water and/or in a pressure vessel under conditions such that the liquid reagents occupy more than 60 per cent of the volume of the vessel.  The need for excess hydrazine, as described in the parent Specification, is thereby avoided.  Instead of the acid and hydrazine, a reagent or reagents yielding these materials on hydrolysis may be used.  Heating is preferably continued until the polymer is fibre forming. Polymerization may be continued by heating until the reactants resinify and the product hydrolysed as described in Specification 626,525 to restore the linear character of the polymer.  In examples: (1) 50 parts of sebacic dihydrazide and 24 parts water were heated at 220 DEG  C. for 2 hours to give a polymer melting at 220 DEG  C. and soluble on prolonged boiling in methanol; (2) similar to (1) using less water and giving a fibre-forming polymer melting at 192-195 DEG  C., soluble in methanol; (3) sebacic acid and two mole equivalents of hydrazine as a 55 per cent aqueous solution were heated at 220 DEG  C. and later 260 DEG  C. to give a fibre forming polymer melting at 175-180 DEG  C., and soluble in hot methanol, and in cresol and formic acid; (4) sebacic dihydrazide was changed into an autoclave so as to fill 83 per cent of the available space, and heated at 220 DEG  C. to give a polymer similar to that of example (1).  For comparison an example is given in which sebacic dihydrazide filling less than 50 per cent of an autoclave was heated to give a polymer melting at 190-195 DEG  C. and broken down by boiling hydrochloric acid.  Specifications 606,701, [Group V], and 613,020 also are referred to.
