Title: Improvements relating to gear cutting machines
Inventor: WILDHABER ERNEST
IPC: B23F5/12
Filed: 1956-02-09
Abstract: 796,072. Gear-cutting. GLEASON WORKS. Feb. 9, 1956, No. 4112/56. Class 83 (3). [Also in Group XXIV] A gear-cutting machine comprises a crank 35, Figs. 2 and 3, for reciprocating a tool-carrier 38, and a drive-connection 51 including a drive-member 96 connected to the work-support to move in a predetermined velocity-relationship therewith, and a driven member 33 rotatable with the crank, and a variable-leverage connection 106-108 between the drive and drivenmembers including a cam 121 that is shaped to provide a non-harmonic motion of the toolcarrier during at least the cutting-portion of its operating cycle. The tool-carrier 38 reciprocates on an arm 23, Fig. 1, adjustable angularly by gearing 32 about an axis 26 on ways 28 formed on a cradle 21 having its axis at 22. The crank 33 is rotated by a motor 40 through a shaft 45, coaxial with the cradle, gears 46, 48, 49, and the drive-connection 51. The workspindle 42 is indexed continuously from the shaft 45 through the gears 52, differential-unit 57, change-gears 63 and worm-gearing 66, 67. The generating-motions are imparted to the cradle from a gear 68, through change-gears 71, a reversing-unit 72, and worm-gearing 76 to the wormwheel 83, and to the work through a coupling 84, gears 85, 88, change-gears 89, gears 92, 94 and a gear 95 on the case of the differential unit 57. The tool-drive connection 51, Figs. 2, 4, 5, comprises the drive-member 96 fast with the gear 49 and carrying a freelymounted slide 104, in which is engaged the pin 106 mounted on the slide 107. The slide 107 carries rollers 117 engaging the constantdiameter, internal cam 121 and drives the driven-member 108 carrying the crank-plate 33 which is adjustable thereon about the axis 34. The crank 35 is radially-adjustable on the plate 33 and is connected to the tool-carrier 38 by the two-piece adjustable rod 36. Thus, as the drive-member 96 rotates at constant velocity, the tool T moves at constant velocity during cutting, but at higher, variable velocity on the return-strokes. Adjustment of the plate 33 and the crank 35 varies the curve of each tooth to produce tooth-bearing of a desired length. (It is stated that in conventional continuous-indexing-machines of this type, the harmonic-motion of the tool, which would produce an S-curvature on the teeth, is compensated by imparting a variable-velocity to the cradle.) The cam 121 may be designed to give a uniform tool-clearance angle. In a modification, the crank 35, Fig. 7, is connected to the slide 38 by way of a yoke 135. Cutter-releasing. A cam-groove 124 in the plate 33 moves a rack-rod 126 to rotate a shaft 39 to relieve the tool.

Abstract: 553,931. Lathe turrets. BENTON & STONE, Ltd., and MILNER, C. E. March 28, 1942, No. 4142. [Class 83 (iii)] A lathe turret has clamping means which may form an attachment unit to replace existing clamping means, comprising a fluid pressure cylinder mounted above the turret and controlled by a hand operated valve. In Fig. 1 the turret d moves on a post which has a threaded part b screwing into the bore of a body member a formed with a pneumatic or hydraulic cylinder f containing a piston h arranged to exert pressure directly on the turret. The body has an inlet passage p, exhaust passage q, and passage r communicating with cylinder f, the supply to which is controlled by a valve having an arcuate groove o by which the cylinder may be connected either to pressure or exhaust. The valve is operated by a spindle v extending from a handle y and having limited angular movement in a cap m retained by screwed ring n. In a modification, Fig. 3, the turret post c is screwed in a support 7 connected by screws 8 to a cylinder f having a piston h. The piston has a wedge-like extension 5 coacting with levers 3 pivoted in the support 7 at 9, the lower ends of the levers being shaped to exert clamping pressure on the turret through a member 4.

Title: Process for the production of a live vaccine against foot-and-mouth disease
IPC: A61K39/135
Filed: 1963-02-01
Abstract: A live vaccine against foot-and-mouth disease is obtained by the serial passage of a virulent foot-and-mouth disease virus through animal cell tissue cultures until the virus is attenuated to such an extent that it still propagates when injected in hooved animals but no longer causes clinically detectable disease, the culture taking place at a temperature below 37 DEG  C. in an aqueous virus developing medium consisting of a physiologically balanced aqueous salt solution containing 0.1 to 0.2% glucose and 0.25 lactalbumin hydrolysate or an amino acid mixture but which is practically free of serum proteins and of bovine amniotic fluid proteins.  Preferably, ambryonic cell tissues are used especially the embryonic kidney epithelium of cattle foetus.  A foot-and-mouth disease vaccine of type C may be so produced.  A non-virulent foot-and-moth disease virus is obtained after the 90th passage.  According to the example, the medium is an aqueous solution of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium bicarbonate, phenol red, glucose and lactalbumin hydrolysate.  Incubation is at 30 DEG  C. for one day, the liquid is collected and represents the first culture passage.

Title: Coupling device for connecting a trailer to a towing vehicle
IPC: B60D1/46
Filed: 1968-01-26
Abstract: 1,208,344. Coupling device. DEERE & CO. 26 Jan., 1968 [27 Jan., 1967], No. 4248/68. Heading A1P. A coupling device for connecting a trailer to a towing vehicle is attached to the latter at three points which form the apices of a triangle. Arms 32 are pivotally connected to the final drive casing 16 of a tractor at one end, and pivotally connected to a coupling jaw 22 at their other end. A plate 25 retains the spacing of the arms on the shaft 28. A single support member 50 is welded at its lower end to the coupling jaw 22 and pinned at its other end into one of a series of holes 56 that afford vertical adjustment. The member 50 may alternatively be telescopic with hydraulic control. Access to power take-off shaft 14 is effected by disconnecting arms 32 from casing 16 and swinging the coupling jaw about bolt 52 until hole 58 aligns with a hole 56 in which it can be pinned. Alternatively the coupling jaw 22 may be rotated about a longitudinal axis of pin 64, so that an overturning trailer does not cause the tractor to tip over.

Abstract: 1,219,271. Computer input. WESTON INSTRUMENTS Inc. 30 Jan., 1968 [30 Jan., 1967], No. 4444/67. Heading G4A. A plurality of telemetry modules receive instructions from a digital computer. Telemetry modules receive analogue, PCM (pulse code modulated) and PAM/PDM (pulse amplitude or pulse duration modulated) data respectively and supply it in standard digital form to a stored-programme digital computer via a module controller which performs parallelto-serial conversion if necessary. In the case of the PAM/PDM module, PDM is converted to PAM before digitization, whereas a PAM input by-passes the PDM-to-PAM converter. Each telemetry module includes sixteen 8-bit instruction registers for controlling bit rate, frame sync. pattern, number of bits per word, number of words per frame, word sync. pattern, odd or even parity &c. These registers are loaded in turn from manual switches on the module or from the computer depending on the setting of a local-remote manual switch on the module. Each 8-bit instruction is accompanied by a 4-bit function address to select the instruction register into which it is to be loaded and, in the case of loading from the computer, also by a 4-bit module address to select the module. Each module contains plugs to preselect the address it will respond to. The contents of the instruction registers are displayed on lamps on the module. A lamp test button is provided which lights all the lamps without disturbing the sorted instructions, and various test points are provided. The setting of the local-remote switch is signalled to the computer which provides an error print-out if appropriate.
