Title: Process for the manufacture of softening agents
IPC: C11C3/00
Filed: 1932-04-11
Abstract: Softening-agents for plastic masses containing albumonous substances such as albumen, blood or casein which are free from ash are prepared by sulphonating animal or vegetable oils such as castor or neats foot oil to a small extent by means of sulphuric acid, working up the sulphonated products in the absence of salts of fixed alkalis and adjusting the titre by means of ammonia or volatile alkylamines such as methylamine.  In an example castor oil is sulphonated and the product, washed with water, is salted out with ammonium sulphate and made slightly alkaline with ammonia.

Title: Improvements in or relating to the hydration of olefins
IPC: C07C29/04
Filed: 1943-06-28
Abstract: Slop acid from an olefin hydration having a sulphuric acid concentration of 35-50 per cent. on an alcohol-free basis is pressure distilled at 350-400 DEG F. and at the vapour pressure of the acid at the chosen temperature for at least 1 hour to produce in the acid a material which acts as an inhibitor of tar formation in a subsequent olefin absorption.  The treated acid is vacuum distilled to 60-98 per cent. concentration and used for further absorption of the inhibitor is extracted with a phenolic solvent such as phenol or cresylic acid and added to fresh absorption acid.  The pressure distillation is generally continued for 1-5, preferably 3 hours, at a pressure varying from about 50-100 lbs./sq. in gauge according to the acid concentration.  This removes volatizable organic material leaving in the acid from .05-.25 per cent. of a resinous oxygen- and sulphur-containing organic material.  Distillation at 1-25 mm. of mercury gives an acid with a total carbon content of .1-.3 per cent. and a soluble carbon content, representing the inhibitor of .05-.1 per cent. which is recycled to the absorber.ALSO:Slop acid from an olefin hydration to, for example, alcohols or ethers, having a sulphuric acid concentration of 35-50 per cent on an alcohol-free basis, is pressure distilled at 350-400 DEG  F. and at the vapour pressure of the acid at the chosen temperature for at least 1 hour to produce in the acid a material which acts as an inhibitor of tar formation in a subsequent olefin absorption.

Fresh acid as make-up may be added up to about 20 per cent without tar formation.  An example describes the application of the process to the absorption of n-butenes from a liquid C4 cut, followed by dilution and hydrolysis to alcohol.

Filed: 1953-04-20
Abstract: 749,310. Locking-screws. NATIONAL MACHINE PRODUCTS CO. April 20, 1953, No. 10802/53. Class 89 (1). [Also in Group XXVII] A self-locking screw, particularly an adjusting-screw in internal-combustion engine valve gear, comprises a hollow, substantially cylindrical threaded body 15, Fig. 9, screwing into an aperture having a thread of uniform pitch diameter and provided with a tool-engageable head 12 and hardened bearing portion 11, the screw being made self-locking by having an intermediate portion 18, Fig. 10, of its threaded part expanded outwards to a pitch diameter such that when the screw is threaded into the aperture the expanded part is an interference fit therein. The leading turn or turns of the screw are of a diameter to screw easily into the corresponding threaded aperture in the valve rocker while one or more longitudinal segments of the intermediate portion are expanded to a greater diameter as shown at 18, 19, 20, Fig. 10. Slots 30 may be provided between the expanded segments to render the expanded portion resilient. In a modification the part 11 is formed as a socket to receive the spherical end of a push-rod.

Title: Improvements relating to hydraulic brakes
IPC: B60T11/22
Filed: 1940-06-25
Abstract: 539,095. Valves. ROVER CO., Ltd., and IVERSEN. P. A. SCOTT-. June 25, 1940, No. 10842. [Class 135] [Also in Group XXXIV] Communication between a hydraulic master cylinder and a reservoir is effected by a non- return valve which is adapted to be opened by the plunger of the cylinder when it is in or near its initial position, and which also serves as a stop for determining the initial position of the plunger. As shown in Fig. 1, the non-return valve h is disposed in a chamber between the master cylinder a and the reservoir connected to the pipe k has a stem m projecting through a passage of greater cross-section so that the valve is tilted to the open position as shown by engagement of a head d on the plunger b with the stem when the plunger reaches the normal position. The stem also serves as a stop for the plunger in this position. If during the return movement of the plunger, the pressure in the cylinder tends to fall below normal the liquid in the reservoir opens the valve against the action of the spring o and flows into the cylinder, the opening movement being limited by engagement of the stem m with the plunger. The spring o may be dispensed with by using a buoyant valve or by disposing the valve below the cylinder instead of above it, so that it is seated by gravity. In Fig. 6, the valve comprises a flanged disc adapted to seat on a tubular part i extending into the cylinder and which is normally tilted to the open position shown by the plunger. Fig. 10 shows a ball-valve h which in the normal position shown is moved off its seat i into a recess formed in the cylinder.

Abstract: 1430194 Ground anchors M SHIBATA 6 March 1973 10845/73 Heading E1B An anchoring device comprises an elongate rod 115, 215; a plurality of arms 127, 227, pivotally connected to the rod, to which are secured cutting blades 125, 225; spring means 135, 235 urging each arm to pivot away from a first position in which it lies along the rod; means 141 for releasably holding the arms in the first position, and means 151 for disengaging the holding means 141; and means 137 for limiting the angle through which each arm can pivot. The rod may be tubular and is extended by coupling on additional shafts 145, 601. The spring means may be either tension springs 135, or a compression spring 235 secured on the rod 215 between a fixed flange 257 and slidable member, and the limiting means may comprise links 241 pivotally connected the arms 227 and the slidable member, the preferred angle of pivoting being not more than 75‹ from the rod axis. An indicator 269 may be provided to show the angle of the arms. The method of securing the device in the ground comprises the steps of lowering the device with its arms closed into a bore; disengaging the holding means; rotating the device to enlarge the bore diameter and raising the device to form a cavity; circulating water through the tubular rod to remove debris; inserting a reinforcing cage in the bore; and filling the cavity and bore to ground level with a hardenable filler such as concrete. The arms may be rotated until this is prevented by the filler material, and the device may be vibrated by a drop hammer to compact the filler material.

Abstract: 128,753. Fairweather, H. G. C., (Beattie, R. M.). July 2, 1918. Parachutes.-In a parachute for use on aircraft, the body of the parachute is folded loosely around a series of umbrella ribs which are acted on by springs to produce an initial opening of the parachute when the enclosing cover is released. Figs. 2 and 3 show the body 1 folded around a series of ribs 3 pivoted at one end to a boss 5 secured to the stem 7, the ribs being opened out by means of springs 6, 6<a> when the two-part cover 11 is released. This release is effected by means of toggle-levers 17 which separate disks 13, 15 between which the cover is held. The parachute ropes 4 are attached to the boss 5, and the folded parachute may be enclosed by a skirt 20 also attached to the boss 5, the arrangement being such that, as the parachute opens, the skirt is turned inside-out and drawn down, together with the boss 5, through the central aperture of the parachute. In a modification, the ribs are opened by means nf stretcher-bars connected to a spring-actuated sleeve sliding on the stem 7. The opening of the parachute may be restricted by means of a rope passing through eyes at the periphery of the parachute and under the control of the airman
