Title: Improvements in or relating to variable-speed power transmission gearing
IPC: F16H29/04
Filed: 1922-07-17
Abstract: 183,456. Lavaud, D. S. de. July 20, 1921, [Convention date]. Variable - speed gearing comprises a swash ring 11, Fig. 1, of variable inclination operating through friction ratchets 19 and a toothed reversing-gear 17, Fig. 2. An annular revoluble casing 3 is pivoted upon a trunnion 4 upon a driving-shaft 1 and carries in ball bear. ings the non-revoluble ring 11. A sleeve 6 slides on a feather on the shaft 1 and has a wedge surface 7 bearing on a cam-face 5 of the casing 3, and serves to tilt the casing. A spring plunger 9 gives the casing 3 the initial push from its normal or no-drive position as the sleeve 6 is withdrawn. The swash mechanism is enclosed in an oil-bath A. Rods 13 with ball ends 12 communicate oscillations to the ratchets 19 which drive a sleeve 14<1> continuously in one direction. A double clutch 18 transmits this or reversed rotation to a driven shaft 14. The rods 13 are in a conical cluster, and their driven ends are in line with the shaft 1.

Abstract: 626,708. Colour patterns. PICARD, V. July 2, 1946, Nos. 19832 and 19833. Convention dates, July 12, 1941, and June 5, 1942. [Class 93] Colours are applied to sheets of flexible material by a method which comprises the steps of stretching on a frame at least one sheet, placing in succession a number of colour carriers behind and close to the back-face of the sheet and applying in succession a number of pressuretools against the front-face of the sheet above a colour carrier so as to create patterns according to the nature of the colour carrier and pressure tool employed. Preliminary tracings of the desired patterns may be made and the colour carrier may be placed on an absorbent support. Figs. 3, 4 and 5 show patterns 3 traced on a fabric 1 which is then stretched out on table 4 and sheets of colour carrier 5 of porous material (e.g. felt, paper and soft wood) which have been soaked with colour from container 6 are placed close to the underside of the fabric which is then pressed from above against these carriers by pressure tools 7.

Title: Improvements in or relating to extrusion
IPC: B29C48/90
Filed: 1959-06-10
Abstract: 880,391. Making tubular thermoplastic articles. SHAW, H. June 10, 1960 [June 10, 1959], No. 19856/59. Class 87(2). An extruded tubular thermoplastic article, immediately on leaving the extrusion die 1, passes in contact with the surface 14 of a cooling member 3, which cools its surface to below the softening temperature of the thermoplastic, and then passes over the surface 15 of a sizing member 4 against which it is sucked by the application of a vacuum, the surface 15 being maintained at a temperature which will not substantially cool the extrusion further. Further cooling and sizing members, e..g cooling members 5, 6 and sizing member 7, may follow. The extrusion is finally cooled to, or near to, ambient temperature by means of a water bath (not shown) or by means of jets 24 of air or water. The surfaces 14, 15, 18, 21 are preferably coated with, or made from, a material having a low coefficient of friction such as polytetrafluoroethylene. The method is particularly applicable to polyethylene piping which is subject to internal stresses that reduce its bursting strength when cooled and stretched simultaneously. The invention is not limited to the extrusion of piping, however, and may be applied to other extrusions, such as channels and troughs. Specification 780,900 is referred to.

Title: Non-destructive read-out memory wire
IPC: H01F10/32
Filed: 1970-04-24
Abstract: 1307592 Magnetic storage devices THOMSON-CSF 24 April 1970 [25 April 1969] 19900/70 Heading H3B A coated wire memory element comprises a wire 10, Fig. 3, on which are deposited a layer 11  of soft magnetic material, a layer 12 of non- magnetic insulating or conductive material, and a layer 13 of hard magnetic material, the two magnetic layers having an easy axis of magnetization along the wire. Writing, which is by successive pulses in the wire 10 and orthogonal conductor 14, magnetizes the layer 12 in one direction or the other along the wire, the flux closing through layer 11, Fig. 4. During reading, a weak pulse in the wire 10 rotates the magnetization of layer 11 to the hard direction so that the flux of layer 12 now closes through the air around conductor 14, Fig. 5 (not shown); at the end of the pulse the flux closes through layer 11 again. Reading thus induces two positive and two negative pulses in conductor 14, the order in which they occur showing whether a "1" or a "0" was stored. Conductor 14 may have a soft keeper film, preferably flexible, Figs. 6, 7 (not shown), to assist the flux closure during reading. Dimensions and compositions are given. Reference has been directed by the Comptroller to Specification 1,054,477.

Patent GB-372620-A (GB)
Title: Improvements in the production of superimposed colloid layers
IPC: G03C1/825
Filed: 1931-07-13
Abstract: In producing superimposed layers of colloid one at least of which is coloured, precipitation of the dyestuff in the solutions for producing the coloured layers, in the layers themselves, or at the boundaries between the layers is caused by the addition of a substance of contrary action.  In one example, a silver emulsion layer is dyed with Chrysophenine G and Acridine Yellow G is added to it.  When an uncoloured layer is applied to this layer no diffusion occurs.  A second layer coloured with Benzo Light Red and Acridine Yellow may be applied.  The Acridine Yellow may be omitted, an extra quantity being then applied to the first layer. The Acridine Yellow may also be replaced by Methyl Acridine.

The tube is curved at its upper end 17 and fitted with a flared end piece 18 the mouth of which is covered by a silk-backed gauze screen 19 spaced away from the open end. The tube may alternatively be flexible or have its sections connected by a universal joint and the housing may include a matching transformer. A suitable transducer having a foil diaphragm is given a sharply rising characteristic by connecting the air chamber at the back of the diaphragm with the space around the energizing coil, which is filled with damping material.

Abstract: 1524915 Determining mutagenesis of diploid cells MASSACHUSETTS INSTITUTE OF TECHNOLOGY 16 May 1977 [24 May 1976] 20405/77 Heading C6F An assay method for determining mutagenesis comprises the steps of: exposing a culture of human diploid or near-diploid cells to an agent to be tested for its mutagenic effects on the cells, incubating exposed cells for a sufficient number of generations (typically covering a period of 12-16 days) to allow them to express phenotypically-developed resistance to a purine which acts as an HGP RT substrate, and determining the fraction of mutant cells. HGP RT represents the hypoxanthine guanine phosphoribosyl transferase locus. According to the preferred procedure, the cells employed are cultured from a diploid human lymphoblastoid cell line, designated MIT-2, the exposed cells are resuspended in a fresh medium before they are incubated and the purine used for the assaying is 6-thioyanine. Other purines are, however, specifically mentioned. An active, drug-metabolizing system exemplified by a post-mitochondrial supernatant of homogenized tissue of human or rat liver in an aqueous suspension medium and nicotinamide adenine dinucleotide, oxidized form may be included in the cell cultures to help in interpreting negative results. The mutagenic agents used recording to the Examples were methylnitrosourea, methylnitro nitrosoguanidine, ethylmethane sulphonate, bromodeoxyuridine and half-mustard substituted acridine.
