Title: Improvements relating to coloured or stereoscopic kinematographic projection of pictures
IPC: G03B33/00
Filed: 1933-08-16
Abstract: 412,061. Colour kinematography ; stereoscopic kinematography. MIKUT, P. O., 6, Gerader Steg, Dresden, Germany. Aug. 16, 1933, No. 22907. [Class 97 (i).] Groups of colour records or stereoscopic pairs, of the same phase, are projected more than once, and from different consecutive positions, by means of a shutter movable over the projecting lenses. As shown, a film 1 bears groups of colour records, each comprising three images, which are projected by means of four lenses o<1>-o<4> and a vertically moving shutter 2. The images a<1>, a<2>, a<3> of one group are first projected by lenses o<1>, o<2>, o<3>. The film and shutter are then moved downwards one image space, and the same images are projected by lenses o<2>, o<3>, o<4>. The cycle of exposures is completed by moving the film downwards one image space and returning the shutter to its previous position, the image a<1> being then projected together with images b<2>, b<3> of the next group. The next downward film movement is effected while the shutter remains stationary, with the result that all the images b<1>, b<2>, b<3> of the next group are projected together as the first of the next cycle of exposures. The image a<1> may be a blue image. Examples of exposures of groups of three images with five lenses, and of groups of two images with three lenses, each group being always projected without inclusion of an image belonging to another group, are described. The shutter may have a series of apertures successively moved into position by rotation of the shutter.

Title: Improvements in and relating to variable speed transmission
IPC: F16H61/02
Filed: 1933-08-18
Abstract: 417,624. Variable-speed gearing. REO MOTOR CAR CO., 1331, South Washington Avenue, Lansing, Washington, U.S.A. Aug. 18, 1933, No. 23116. Convention date, Jan. 16. [Class 80 (ii).] Variable - speed gearing comprises a planetary train so controlled by eccentrically rotating weights O, O<1>, Fig. 1, that speed changes are automatically effected between a definite low speed and solid high-speed drive. The planetary member is a doubly toothed ring E, Fig. 2, which turns loosely around an eccentric E<1> fast to a rotary carrier plate G. The ring E meshes internally with a sun gear C fast on a driving-shaft A, Fig. 1, and externally with an internal ring D integral with a drum N fast on a driven shaft B. The cranked weights O, O<1> are supported on spindles M loosely journalled in the drum N and carrying pinions J meshing with a gear ring K rigid with the planet carrier plate G. If the load is sufficient, the train C, E, D operates as a simple step-down in speed, the planet-carrier G being kept from turning backwards by a roller detent I. As the speed increases, or the load decreases, the drag of the cranked weights O, O<1> on the gear ring K is sufficient to rotate the eccentric E<1> forwardly, so that the speed of the driven shaft B increases. The increase may be up to equality with the driving-shaft A.

Title: A process for making patterns for use in the production of articles of attire
IPC: A41H3/04
Filed: 1951-12-05
Abstract: At least one layer of a fabric of a cellulose derivative, e.g cellulose acetate, that is capable of stretching is applied to a part of a human body, the fabric being applied in tension to conform to the shape of the part.  Before or after the fabric is thus applied it is treated with a volatile liquid that exerts a solvent action on the fabric.  The liquid is allowed to evaporate whilst the fabric is on the body, whereby the fabric is rendered substantially incapable of stretching, and the fabric thus treated is removed in the form of a flexible mould.  This mould may be a pattern for a dress or for making corsets, brassieres, gloves, surgical belts and footwear.  The fabric may be knitted, woven or felted cellulose acetate fabric.
