Patent GB-2068962-A (GB)
Title: Process for preparing valproic acid
IPC: C07C51/06
Filed: 1981-02-11
Abstract: Di-n-propyl acetic acid is obtained in higher yields by hydrolysing di-n-propyl acetonitrile with concentrated sulphuric acid at an elevated temperature to form di-n-propyl acetamide and then reducing the concentration of the sulphuric acid in the reaction mixture and refluxing it at a generally higher temperature to convert the acetamide into di-n-propyl acetic acid. Recovery of the acid product is advantageously effected by the passage of a steam jet through the reaction mixture, since this enables a purer product to be obtained, in particular a product containing a smaller quantity of valeric acid as impurity.

Title: A cinefilm cassette and a method of using this cassette during exposure, development and playing back of the film
IPC: G03C5/26
Filed: 1981-09-10
Abstract: A cinefilm cassette (1) consists of a flat, preferably rectangular cassette housing (1a, 1b) with winding and rewinding mechanisms (10) situated in one plane. The cassette (1) comprises on either side of a narrow side a labyrinth-like opening (3). The cinefilm (5) emerges from one of the openings (3), is freely accessible guided over the narrow side and introduced into the other opening (3) after use. The cinefilm cassette (1) is provided with at least two data panels of which one panel is intended for visually-readable optical data and the other for machine- readable magnetic data. After the film has been exposed and the cassette removed from a camera, the cassette is first delivered to a data input unit 34, then the film is detached from a leader 32 and attached to a film from a preceding cassette and passed through a developing machine 30. When the film has been unwound from the cassette it is detached at its other end from leader 33 and attached to a following film. The empty cassette is conveyed at the same speed as the film to the output end of the developing machine where the first detached end is rejoined to leader 32, the film is wound back into the cassette and then the other end is detached from the following film and rejoined to other leader 33. The cassette then passes to a data reading and addressing station 31 and is then returned to the customer for projection. The use of the same cassette casing and winding mechanisms during exposure and projection lessens the danger of loss during mailing. <IMAGE>

Title: Improvements in and relating to envelope gaskets
IPC: F16J15/10
Filed: 1957-04-25
Abstract: 876,367. Joint-making packing. ANGUS & CO. Ltd., GEORGE, BAKIN, M., and TURNER, D. G. April 17, 1958 [April 25, 1957], No. 13187/57. Class 122 (3). A method of making a gasket envelope of plastic material, especially a fluorocarbon such as polytetrafluorethylene or polytrifluorochlroethylene, comprises winding thin tape of the material around a mandrel in layers, wound in opposite directions, until a sufficient thickness has been built up and then subjecting the taped mandrel to pressure and to heat to cause merging together of the layers into a homogeneous envelope which is then removed from the mandrel. In the example described, polytetrafluorethylene powder is mixed with a volatile liquid, such as a solvent naphtha, and compressed to a preform from which tape 1 is extruded which when dried, or whilst still moist, is wrapped toroidally around a mandrel 2, which is preferably chromium-plated, with a half width overlap of successive turns and reversal of direction of winding in successive layers 1a, 1b, 1c, 1d. The taped mandrel is placed between chromium-plated steel plates 4, 5 and pressed cold in an hydraulic press from which it is then removed with its plates and, if moist tape has been used, allowed to dry or dried by heating, before baking in an oven to fusion temperature, e.g. for one hour at 360‹ C., after which it is replaced in the cold press, subjected to pressure and allowed to cool. Finally, a peripheral edge 6 of the polytetrafluorethylene sheath is cut off, as indicated at X-X in Fig. 2, and the sheath removed from the mandrel to provide a channel section gasket envelope.
