Title: Improvements in or relating to infinitely variable change speed gears
IPC: F16H15/38
Filed: 1956-09-11
Abstract: 870,912. Variable-speed friction gear. PERBURY ENGINEERING Ltd., and PERRY, F. G. DE B. Sept. 11, 1957 [Sept. 11, 1956], No. 27760/56. Class 80 (2). A steplessly variable friction gear of the kind wherein precessionally rocked non-planetating rollers 14 are mounted between driving and driven toric discs 10, 12, and traction pressure is applied by a torque-responsive cam-and-roller device 15, has an axially-resilient member such as a Belleville spring 24 between one of the toric discs and the shaft on which it is mounted, thereby resiliently supporting any axial pressure due to separation of the discs. Input shaft 1 is dogged to a driving-member 8 of the cam device which co-operates through rollers 15 with the driving disc 10 which rests for a slight tilting movement on a land on a drive-shaft 17 and is rotationally connected to it by dogs 20. The cam-rollers 15 are prevented from radial movement by a cage 16. The thrust produced by the cam device is transferred from the driving member 8 through a thrust-bearing 21, Belleville spring 24 and flanged nut 25 to the driveshaft 17 to which another driving toric disc cooperating with another set of friction rollers (not shown) is fixed, thereby developing a thrust between the driving discs. Further Belleville springs 29 provide initial axial loading which is limited when the outer Belleville spring 24 contacts the thrust-ring 23. The opposing cam faces 9, 8<SP>1</SP>, Fig. 2, of the loading device comprise a linear portion C separated by a curved portion, the curve of which is shown at D. The Belleville spring 24 has a resiliency which exceeds the upper limit of axial loading for which the gear is designed. Two Belleville springs may be provided. Specification 870,913 is referred to.

Title: Improvements in and relating to processes and devices for producing a light for photography, from light sources having a variety of light ray proportions
IPC: G03B7/16
Filed: 1929-09-13
Abstract: 341,904. Colour lighting; incandescent electric lamps. BERTLING, H., 92, Wilmersdorferstrasse, Charlottenburg, Berlin. Sept, 13, 1929, No. 27908. Convention date, Oct. 27, 1928. [Classes 39 (ii), 75 (ii), and 75 (iv).] For the purpose of producing correct colour brightness for monochrome photography and correct colour values in colour photography the light emitted from a source is adjusted in accordance with the sensitiveness of the sensitized photographic emulsion, by dividing the emitted light into a number of parts correcting one or more parts and reuniting them before they reach the object to be illuminated. In one method of carrying out the invention, light from a source is in part permitted to radiate directly to the object, and is in part reflected by a reflector a after passing through a colour screen b. The colour filter b is such that the illumination of the object by the combination of the direct and reflected rays corresponds to the sensitivity curve of the photographic emulsion. A numerical example is given in the Specification. In other methods the arrangements of the reflectors and filters are modified, a typical form being shown in Fig. 7, in which part of the light bulb constitutes the filter b and is coated with a reflecting layer a. The part of the light bulb not constituting the filter b may be coloured differently from the filter b. Specification 290,583, [Class 75 (iv), Lamps &c. Kinds &c. of], is referred to.
