Title: Improvements in or relating to manually-operable fastening means for windows, doors and the like
IPC: E05C1/04
Filed: 1935-02-19
Abstract: 452,295. Fastenings. REA, E. E., Petts Wood Lodge, St. John's Road, Petts Wood, Kent, [Representative of REA, W.], and WITCOMBE, J. G., 63, Manor Park, Lewisham, London. Feb. 19, 1935, No. 5361. [Class 44] In a hand-operated fastening combined in an unitary structure with a keyless locking device distinct from the fastening, the locking device is arranged to hold the fastening means in both its closed and open positions. The locking device is preferably of the type described in Specification 436,283. Figs. 1, 2 show a pivoted window fastening of known type comprising a lever pivoted at 12 on a bracket 22 secured to the hinged frame 14 of the window, part 10 serving as a handle and part 11 engaging a piece 16 on the fixed frame 18 in the closed position, or a slot 20 in part 11 engaging a flange of the fixed frame to hold the window partly open. A segment 30 is provided on part 11, the locking bolt 26 (controlled by permutation code rings 28) engaging edges 31, 32 in the fastened and released positions respectively. An application to a sliding bolt fastening is described, the bolt being operated by a knob thereon. The lock bolt enters a recess in the fastening bolt to hold the latter retracted, and may enter a recess or engage behind the tail of the bolt to hold it shot. Figs. 5, 6, 8 show the application to a latch bolt 46 which can be further shot to act as a lock bolt. The bolt 46 is biassed to shot position by spring 50 and has a recess 52 in which is slidably disposed a rack 54 operated by pinion 58 and handle 60. The auxiliary bolt 26 co-operates with handle boss 59, and when it is engaged in arcuate recess 63 bolt 46 may operate as a latch retractable by handle 60. When bolt 26 is withdrawn bolt 46 may be shot further into the keeper and locked there by bolt 26 engaging a recess 62.

Title: Lawn mowers
IPC: A01D34/42
Filed: 1932-02-23
Abstract: 388,926. Lawn-mowers. GRATIOT, C. A., 191, East 34th Street, Portland, Oregon, U.S.A. Feb. 23, 1932, No. 5363. [Class 6 (ii).] The rotary cutter-head of a lawn-mower comprises blade carriers mounted on a shaft and driven from it through resilient means connected to them. The blades are made flat and resilient with their cutting-edges normally at a greater distance from the axis of rotation than the edge of the co-acting ledger blade. The shaft 4 of the rotary cutter is fixed in position relative to the ledger blade 8. The cutter blades 20, 21 are fastened to arms 17, 18 projecting from hubs 9, 10 journalled on the shaft 4 and operated by driving-pieces 5, 6 rigidly connected to the shaft. The cutters are driven through spring rods 7, 11 passing through holes 19 in the arms 17, 18 and in projections on the driving-pieces 5, 6. The planes of the steel blades 20, 21 of alternate sets are inclined. at opposite angles to the shaft 4, and the paths of adjacent sets overlap. The planes of the blades of each set are parallel to planes intersecting in lines which intersect in a point in the axis of the cutter, or which pass through a small circle normal to the axis and central of the axial length of the knives. The outer surface of each blade 20, 21, which normally projects beyond the ledger blade 8 and makes contact with it when in action, is approximately that marked off on a cone by two oblique parallel planes intersecting it, the frustrum between the planes containing the figure of the blade.

Title: Improvements in the production of n-arylimino-succinic acid esters
Filed: 1951-03-06
Abstract: A process for the production of N-arylimino-succinic acid esters by condensation of primary aromatic amines with oxalacetic esters consists in reacting the solutions or suspensions of the alkali metal derivatives of oxalacetic esters consisting of the reaction mixture obtained by condensation in alcohols of oxalic acid esters with acetic acid esters and alkali metal alcoholates directly with salts of the primary aromatic amines. Alternatively, the free amine may be added to the reaction mixture followed by an equivalent of acid, e.g. hydrogen chloride gas. Amines mentioned are aniline and its homologues and their nitro, halogen and alkoxy substitution derivatives, as-dialkyl-p-phenylene diamines, naphthylamines and amino pyridines.  Suitable salts are e.g. hydrochlorides, sulphates, acetates and formates.  In an example, dimethyl oxalate, methyl acetate and sodium methylate are reacted together.  o-Anisidine hydrochloride is added to the reaction mixture and reaction continued to give o-methoxy-phenylimino-succinic acid dimethyl ester. N-Phenylimino-succinic acid dimethyl ester is prepared similarly from aniline.

Title: Improvements in and relating to the treatment of latex
IPC: C08C1/02
Filed: 1940-04-10
Abstract: Latex of indiarubber, gutta percha or balata of low protein content is prepared by displacing part of the protein adsorbed by the rubber &c. particles by a capillary-active substance which is more strongly adsorbed than the protein.  Suitable substances are the soaps such as the sodium, potassium, or ammonium salts of the higher fatty acids, or of the naphthenic acids; the sulphates and sulphonic acids derived from the higher alcohols, polyglycerol, esters, saponines &c., and colloidal solutions of phosphatides, lipins and lipoids.  The latex is preferably diluted and is left in contact with the soap for a period of time which may be several hours before centrifuging or creaming.  The process may be applied to latex which has already been concentrated by centrifuging or creaming.  The fatty acids present in the wet sheet rubber &c. prepared by the process are removed by extracting with dilute ammonia or other alkaline solution.
