Title: Improvements in and relating to transmission gears
IPC: F16H15/50
Filed: 1951-07-04
Abstract: 715,038. Friction gearing; variable-speed gearing. (LUTZ. O. July 4, 1951 [July 5. 1950; Aug. 24, 1950; Nov. 10, 1950; Dec. 11, 1950; Feb. 24, 1951], No. 15889/51. Classes 80 (1) and 80 (2) A ball transmission gear comprises two co-axial sets of interengaging balls 61, 62 at least one of the four races 63, 64, 65, 66 being axially displaceable and the two outer races 63, 64 being rigid with each other, while spring means maintain the balls in contact with the tracks. All the races may be conical in which case the gear ratio is invariable, but, as shown, at least one of the races is concavely grooved so that the gear ratio is varied in accordance with the axial displacement. In one form, the outer races 63, 64 are stationary, the inner race 65 being spring-mounted and axially displaceable on the driven shaft while the inner race 66 is rigid with the driving shaft. As shown in Fig. 5, however, the gear is combined with an epicyclic gear, the races 63, 64 being rigid with the driving shaft 28 which also carries an annulus 72, the planet carrier 88 being rigid with the driven shaft 78, the race 65 being rigid with a sun 73, and reverse rotation of the race 66 being prevented by a one-way detent 76. Race 66 can be moved so far to the left that a cone clutch 75 between races 64, 66 engages, to effect direct drive. With this clutch disengaged, the gear ratio is dependent on the relative axial position of race 66. Alternatively, the clutch may be omitted and the race 66 held stationary by means such as a brake. The gear can be rendered automatic in accordance with load by employing helically-toothed wheels in the epicyclic gear. In the form shown in Fig. 4, two epicyclic gears, with a common carrier 60, are used. The outer races 63. 64 are rigid with the driving shaft 77 and with one sun 45, the races 65, 66 provide the two gear annuli 49, 50, and the other sun 53 is rigid with the driven shaft 78, the race 66 being held stationary. The spring pressure is applied by the resilient flanges 55, 56 of the races 65, 66.

[Also in Division F4] A film is made by heating and/or shaping a polymer having recurring structural units -CH 2 -C(CH 3 ) 2 -COO- into a completely molten film not more than 10 mil thick, and quenching in a liquid held at below - 25‹ C. The starting polymer may be bulk polymer or shaped products and has inherent viscosity of at least 0À8. The film may be made continuously, e.g. by extrusion of a melt directly into the liquid quenching bath. Alternatively, the polymer may be pressed in a heated hydraulic press with the upper plate at a higher temperature or with a lower heat capacity than the lower plate. It should then enter the quenching liquid preferably within 2 seconds. With films of thickness less than 3 mils, e.g. 1 mil or less, metal plates may be employed to help maintain the film in a molten state while being transferred to the quenching bath. The film need be retained in the quenching bath only long enough to reduce its highest temperature to 20‹ C. The film has X-ray crystallinity less than 50%, and is clear, transparent and unoriented and may be line-drawn at room temperature up to seven times the original length; or oriented by stretching at 170-200‹ C. to 4 times the original length; or the film may be stretched biaxially. A crazed grid pattern may be applied by pulling the lowcrystallinity film over a knife-edge and in this way it may be made optically imhomogeneous so that, depending on the angle of vision, the film is opaque, birefringent or transparent. Two such films placed with surfaces parallel but grid directions orthogonal appear opaque when seen in all directions except the normal, when they appear transparent; or the same effect may be produced by crazing first in one direction and then in the other, and these films may be used as laminates to glass on greenhouses, automobile headlights or searchlights; they may also be used as diffuser screens for light sources.
