Title: Improvements in corrugated sheet piling
IPC: E02D5/04
Filed: 1927-06-23
Abstract: 273,314. Meiser, J. June 28, 1926, [Convention date]. Piling.-In sheet piling of corrugated form, the interlocking joints are constituted by overlapping parts which together form the top or bottom portion of a single ridge or groove, the edge of the one sheet fitting behind a projection on the other sheet, and the end of the latter bearing against a projection on the first sheet. Preferably, the edges of the sheets are wedge shaped and engage in corresponding recesses in the projecting parts. The edge a, Fig. 1, of one sheet is flanged and bears against a projection b on the other sheet, while the edge c of the latter bears against a shoulder d on the inside of the first sheet. The edges and projections may form single or double wedges as shown in Figs. 2, 3 and 3<a>. Figs. 4, 5 and 7 show members of various forms assembled. The joints are arranged outside the neutral axis of the wall, and may be-alternately on each side or all on the same side. 'The joints may be thickened as shown in broken lines in Fig. 1, and the angle of -the bendin the locking members may vary so as to produce either flattened or more arched corrugations. The locking members may be angular instead of rounded.

Title: Improvements in and relating to taps and cocks
IPC: F16K17/38
Filed: 1931-06-09
Abstract: 374,629. Plug cocks. LEATHER, T. A., 6, New Lorne Street, Moss Side, Manchester. June 9, 1931, No. 16743. [Class 135.] A valve particularly adapted for use in petrol pipes has a hollow rotatable plug within which is a second rotatable plug, the latter being urged to its open or closed position by a spring loaded by rotating the second plug and maintained loaded by an inflammable detent which when burned allows the second plug to open or close the tap or cock. The cock casing 5 has a through passage 7 and is screwed at the ends 6 for attachment to a petrol pipe or the like. A plug 8 having a screw at its narrow end is held in a transverse tapered passage by a washer 10 and nuts 11. A second plug 17 having an integral spindle 20 with an enlargement 21 at its wide end rotates within the plug 8 and is prevented from jamming therein by a hard ball 19 at its narrow end. A cylindrical extension 15 of the plug 8 having a cover 16 in which is a washer 22 houses a spring 24 secured at its ends to pins on the spindle 20 and extension 15. The spring 24 is maintained in tension by a screw 26 on the spindle 20 which is kept in a slotted opening 27 in an arm 28 on the cover 16, by a fusible sleeve 29. When used as a petrol cock the ports 14 in the plug 8 are normally aligned with a port 18 in the plug 17 so that in case of fire the sleeve 29 fuses and the cock is closed by rotation of the plug 17. The plug 8 is also provided with a handle 12 and a knighting pin 13. When applied to fire extinguishers, the cock is closed in the loaded position of the spring.

Title: Process for the preparation of phenylalanine and derivatives thereof
Inventor: TANAKA MASAO
IPC: B41N1/14
Filed: 1965-04-21
Abstract: Phenylalanine or an N-acyl derivative or carboxylic ester thereof is prepared by reacting an O-aryl sulphonic acid ester, an O-alkyl-sulphonic acid ester or an O-sulphonic acid ester of tyrosine or of an N-acyl derivative of tyrosine, a tyrosine ester, or an ester of an N-acyl tyrosine, with hydrogen in the presence of a hydrogenation catalyst.  Any optical activity present in the starting material is retained in the product.  In the examples (a) O-tosyl-L-tyrosine is hydrogenated to give L-phenylalanine, (b) O,N-ditosyl-L-tyrosine is hydrogenated to give N-tosyl-L-phenylalanine which is hydrolysed to give phenylalanine, and (c) N-acetyl-O-tosyl-L-tyrosine is hydrogenated to give N-acetyl-L-phenylalanine. Other starting materials mentioned are the O-methane sulphonate, O-ethane sulphonate and O-sulphuric acid esters of tyrosine, N-tosyl tyrosine, N-acetyl tyrosine, N-benzoyl tyrosine, N-carbobenzoxy tyrosine and N-carboethoxy tyrosine and their methyl, ethyl and benzyl carboxylic esters.

Title: Process and machine for the manufacture of biscuits
IPC: A21B5/02
Filed: 1936-06-19
Abstract: 465,695. Making biscuits. GIRODIN, M. E. June 19, 1936, No. 17060. Convention date, March 6. [Class 28 (i)] In the manufacture of biscuits, a continuous film of paste is formed upon a moving heating surface, and when baked is wound helically to form a tube which is cut into lengths. As shown, the heating surface is an annulus 1 supported by rollers 4, 5, the annulus being inclined so that the roller 5 is at the lowest part. The arrow f<1> shows the direction of rotation. The annulus is heated by a gas burner 2. Above the ascending part of the annulus is arranged a paste reservoir 18 connected by a pipe 20 and cock 19 with a number of small pumps 21 driven by an eccentric 25 on the shaft 32. A cam 30 on the shaft 32 actuates a lever 28 on an oscillating valve having passages which connect the suction of the pump to the reservoir 18 and the discharge to the nozzles 38, 39. The nozzles 38, 39 are directed in opposite directions, and are transversely spaced so that the strips of paste 39a issuing from the nozzles 39 lie between the strips 38a issuing from the nozzles 38. The strips, by flowing, form a film which is continuous transversely and longitudinally. The paste begins to dry before entering the heating tunnel 72 which incorporates an electric or gas radiator. At the exit of the tunnel is provided a blade 55 of willow-leaf section on which the baked paste is wound helically. The strip is detached from the annulus by a scraper 73, and the blade is raised and lowered, during its rotation, by a cam 56 of similar shape to the blade section resting on a fixed roller 57. The arms 50 are pivotal on the shaft 16 to permit this. Owing to the angle of the blade 55 to the direction of movement of the baked strip, the wound strip slides towards and over the end of the blade, the overhanging part of the biscuit being cut off by scissors 58 operated through linkage from a cam 69. A rotary brush 40'on the shaft 41 spreads grease from a reservoir 48 on to the annulus before it receives fresh paste.

Title: Process for the production of polyvinyl halides of high molecular weight
IPC: C08F14/06
Filed: 1931-06-22
Abstract: In the polymerization of vinyl halides by heating in closed vessels in the presence of peroxide catalysts, in the absence of solvents and, if desired, in the presence of organic acid anhydrides, polymerization products of high molecular weight and comparatively uniform degree of polymerization are obtained by interrupting the polymerization when a considerable amount, say one-half, of the monomeric vinyl halide is still present, and separating the polymerization product by distilling off the monomeric vinyl halide. The vinyl halide may be subjected to a preliminary irradiation, e.g. by passing through a quartz tube illuminated by a mercury vapour lamp prior to admission into the autoclave, whereby the polymerization is accelerated.  In examples, vinyl chloride is polymerized: (1) at 35-45 DEG  C. with the aid of barium peroxide, in the presence of acetic anhydride; (2) at 50-60 DEG  C. with the aid of benzoyl peroxide.  In each case about one-half of the vinyl chloride is polymerized.  The vinyl chloride may be replaced by vinyl bromide or by a mixture of these two halides.ALSO:In a process for the polymerization of vinyl halides by heating in closed vessels in the presence of peroxide catalysts, in the absence of solvents, and, if desired, in the presence of organic acid anhydrides, the process being interrupted when a considerable amount, say one half, of the monomeric vinyl halide is still present, the polymerization is considerably accelerated if the vinyl halide is subjected to a preliminary irradiation, e.g. by passing through a quartz tube illuminated by a mercury vapour lamp prior to admission into the autoclave.
