Title: Improvements in lathes for machining locomotive wheels
IPC: B23B5/28
Filed: 1927-05-18
Abstract: 297,351. Lurf, K., and Collett & Engelhard Werkzeugmaschinenfabrik Akt.- Ges. May 18, 1927. Lathes; chucks.- Relates to lathes for turning locomotive wheels in position on their axles, the wheels having long crank pins serving both for the connecting and the coupling rods and carrying outside cranks for operating the valve gear, and consists in means for mounting and operating the lathe centres. The left hand headstock, Fig. 4, is fixed to the bed and the right hand headstock is traversable by means operated by an electric motor 17. The wheels are introduced into position whilst the headstock: are separated, the crank pins and valve cranks being received in recesses 3 provided behind the centres 2. The headstocks are then closed engaging the centres with the axle and compressing springs 7, Fig. 1. The movable headstock is clariped by a series of wedges 15 confined between an end wedge 16 secured to the headstock and a loose wedge, the wedges being self releasing. A fixed stop 14 arrests the loose wedge, causing clamping to occur. This arrangement may be duplicated on the other side of the bed. An excess current switch then cuts off power from the motor 17. The centres 2 are carried by frames 3 sliding in collets 4 which grip the front ends of the frames at 10 by engagement with the coned ends of the hollow spindles 6. The collets are mounted on screwed sleeves 5 attached to the frames 3 and slide with the centres during the compreession of the springs 7. After the motor 17 is cut off, the centres are further advanced into the axle by means of gear or hand wheel operated spindles 8 splined in the sleeves 5. When the resistance to movement of the centres exceeds the pressure exerted by the springs '7, these yield, closing the collet tightly on the frames 3. The above movements are reversed when the wheels are to be removed from the lathe and the outward movement of the headstock is limited by a switch the lever of which is mechanically actuated by the headctock.

Filed: 1955-05-09
Abstract: The invention comprises two new compounds and polysiloxane gels prepared from them, the compounds being bis-heptamethylcyclotetrasiloxanyl-methane <FORM:0783313/IV (a)/1> and diheptamethylcyclotetrasiloxanyl <FORM:0783313/IV (a)/2> They are prepared by irradiating octamethylcyclotetrasiloxane with high energy electrons or with ultra-violet rays, a solution being formed of the two compounds in the siloxane.  The polysiloxane gels are prepared from this solution by heating with an organopolysiloxane polymerization catalyst.  The solutions preferably contain 0.1 to 10 per cent by weight of one or both of the compounds and 0.001 to 0.5 per cent of catalyst.  The new compounds, which may be separated by fractional distillation, are useful per se as lubricants, lubricant additives, hydraulic fluids and as cross-linking agents for polysiloxanes.  The Specification describes an apparatus for effecting the irradiation.  Suitable radiation doses are from 1 X 106 to 1 X 109 Roentgens. The apparatus is preferably kept in vacuum or in a nitrogen atmosphere if the radiation lasts longer than about a minute. Prior to polymerization, the octamethylcyclotetrasiloxane solution is preferably freed from dissolved air by evacuation. Suitable catalysts are sodium, potassium and caesium hydroxides, and transient catalysts such as solid quaternary ammonium hydroxides, e.g. tetramethyl and benzyl trimethyl ammonium hydroxides, and quaternary phosphonium compounds, e.g. tetra-n-butyl phosphonium hydroxide and butoxide, and tetraethyl and butyl tricyclohexyl phosphonium hydroxides.  Other cyclic dialkyl- or diaryl-siloxanes may be added to the solution before polymerization.

May 12, 1932, No. 13715. Convention date, June 24, 1931. [Class 39 (i).] I n regulating the light of alternating - current luminous tubes by controlling the discharge period in each half-wave by varying the phase-shift on one or more electrostatic control electrodes near the main electrodes, the usual series resistance is omitted and the phase-shift is so controlled that the discharge only takes place during the descending part of each half-wave shortly before the potential drops to zero. The discharge starts at each point 3 of the potential curve 1 and a heavy current peak 4 occurs, no damage being done to the tube since the point 5 at which the voltage can no longer maintain the discharge is quickly reached. The tube may have a hot cathode and two anodes each with surrounding control electrodes, or may have two hot cathodes each with an adjacent control electrode. To facilitate starting at the point 3, a constant auxiliary ionization is maintained by a highfrequency discharge. Specification 371,673 is referred to.

Title: Improvements in edge-trimming shears for metal plates
IPC: B23D31/04
Filed: 1964-04-03
Abstract: 1,037,454. Shearing. SCHLOEMANN A.G. April 3, 1964 [April 13, 1963], No. 13812/64. Heading B3W. In a reciprocating shear for trimming the edges of plates the movable blade is inclined at an acute angle to a surface supporting the plate and in the open position overlaps the stationary blade, the angle of inclination and the length of the cutting stroke being such that at the end of the cutting stroke the entry end of the movable blade is spaced away from the support by a distance equal to the thickness of the plate to be cut, and there are auxiliary transverse cutters situated at the delivery end of the blades for cutting up the strip trimmed from the plate edge. The blade 2 reciprocates in the frame 1 and co-operates with a stationary blade 6, the cutting edge of which is level with a surface 4 which supports the plate 5. A transverse cutter 10 is secured to the blade 2 and a co-operating transverse cutter 11 is secured to a blade-holder 14 which is moved vertically by a fluid cylinder 16 acting through a toggle mechanism 15. The shear is shown in the open position in Fig. 1, and in this position the distance between the upper blade and the lower blade is less than the thickness of the plate to be cut. Operation.-The plate 5 is pushed between the blades in the direction of the arrow 20 until it strikes the upper blade and is then clamped by hold-downs. The blade 2 descends to trim the plate-edge and returns to the position shown. The plate is pushed further through the blades, the cutter 11 having previously been lowered so that the passage of the trimmed strip which is bent down is not obstructed. The cutter 11 is then raised to its operative position and on the next stroke of the shear co-operates with the cutter 10 to chop the trimmed-off strip transversely. In a modification, the machine is inverted.

Abstract: 311,334. Scurlock Gear Corporation, (Assignees of -Fickett, E. L.). May 9, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Differential balance or gearing comprises bevel gearing with spiral teeth constructed so that the teeth are in engagement at their ends b as well as either at their outer gear or pitch surfaces c or at their inner gear surfaces i. To this end, the teeth of gear 7 project far enough within teeth of companion gear 5 so as to be overhung. Planetary gears 7 drive side gears 5, 6 differentially. The effect of the end engagement at b is to prevent gears 7 from tilting. The effect of the spiral, which is inclined at about 55‹ to the pitch circle, is to produce internal friction, so that when one road wheel encounters a slipping surface, it does not spin, and the other wheel continues to drive.
