Title: Improvements in or relating to preparations of modified products of galactomannans, polyuronic acids and galactans
IPC: D21H17/24
Filed: 1963-08-16
Abstract: Modification products of galactomannans, polyuronic acids, galactans and mixtures thereof and with other thermally degradable carbohydrate material are made by dehydrating under vacuum, at increasing temperatures insufficient to cause pasting in the mass, a finely-divided mass of the substance in native form or in pretreated or degraded form, optionally in presence of degrading or derivatizing agent and then, while excluding oxygen from the mass, treating it thermally or thermally and chemically and cooling the mass while excluding oxygen from it.  The thermal and chemical treatments, and the cooling, may be effected in a reducing, or inert atmosphere, e.g. in CO2, SO2 or nitrogen, at subatmospheric or super-atmospheric pressure, or in a vacuum.  The thermal treatment temperature, e.g. 130-180 DEG  C. may be higher than the maximum dehydrating temperature, e.g. 90-110 DEG  C.  Specified starting materials are carob gum, quar gum, locust bean gum, tragacanth, gum arabic, pectin, algin, carrageenin and agar.  They may have been pretreated by grinding or by chemical or enzymic action.  Degradation may be accelerated by addition of inorganic or organic acids or salts. Ethers, esters, acetals or nitrogenous derivatives may be formed by use of reactants such as ethylene or propylene oxides, monochloroacetic acid, formaldehyde, acetaldehyde, glyoxal, polyoxymethylene, ammonia, urea, hydrazine, triethanolamine, or trimethylamine. Prior to the cooling step, the pH of the reaction mixture may be adjusted.  The process is preferably carried out in autoclaves with temperature control and continuous stirring. Examples describe the dehydration, in presence of hydrochloric acid, of quar flour, caruba flour, and mixtures of quar flour and potato starch; and reaction of a mixture of quar flour and starch with polyoxymethylene.

Salts mentioned are the chlorides of Zn, Sb, Ti, Sn, Al, B, In, Bi and Si.
Patent GB-763554-A (GB)
Title: Process for the treatment of chromized articles
IPC: C23C10/60
Filed: 1954-11-11
Abstract: A process for improving the physical properties of chromized steel articles, the steel having a carbon content not exceeding 0.1 per cent or whose carbon is bound in a stable manner by carbide forming elements, e.g. Ti, Ta and/or Nb. and having a substantially carbon-free chromized surface, comprises cooling the articles rapidly from temperature above 900 DEG C. after chromizing.  The articles may be cooled directly from the chromizing process by quenching in oil or water or they may be cooled to room temperature, reheated to 950 DEG C. and quenched.  The reheating may take place in a protective gas atmosphere, e.g. incompletely burned illuminating gas, which may contain sufficient oxygen to produce a surface of green oxide of chromium.

Title: Voltage and load compensated flasher
IPC: B60Q1/38
Filed: 1966-07-21
Abstract: 1,106,350. Flashing signals. TUNG-SOL INDUSTRIES Inc. 21 July, 1966 [15 Sept., 1965], No. 32790/66. Heading G4Q. [Also in Division H1] A two terminal voltage and load compensated flasher comprises a first unit having two pairs of normally closed contacts 16, 18 and 36, 38 adapted to open upon expansion of a current responsive element 14 with passage of current therethrough, a second unit having a pair of normally open contacts 28, 30, and means operative when the contacts of the first unit are open for initiating closure of the normally open contacts. The first unit comprises a blade 12 held against its natural bias by pull ribbon 14. The second unit comprises an arm 24 welded to leaf spring 26 tending to close contacts 28, 30 but restrained by pull wire 22. When switch 42 is closed current flows from battery 45 through blade 12, ribbon 14 and contacts 16, 18 to light the lamp 40. Ribbon 14 heats up and expands allowing blade 12 to snap open contacts 16, 18 and 36, 38 when the lamp 40 goes out. The current then flows through resistor 34, wire 22 and arm 24, this is insufficient to light the lamp but sufficient to heat up wire 22 causing it to expand and allow contacts 28, 30 to close. During this time ribbon 14 has been cooling and contracting till it closes contacts 16, 18 and 36, 38. Current then flows through blade 12, contacts 36, 38, contacts 30, 28, arm 24, short circuiting wire 22 and ribbon 14, and lamp 40 is lit. Wire 22 cools down and contracts opening contacts 28, 30 thus the current flows through blade 12, ribbon 14 contacts 16, 18 and lamp 40 and ribbon 14 again heats up starting the cycle again. The time lamp 40 is off is the cooling time of ribbon 14 which is constant regardless of voltage and current and the time lamp 40 is on is the cooling time of wire 22 plus the heating time of ribbon 14 which sum is constant regardless of voltage and current. Figs. 6 and 7 (not shown) show the heating and cooling times of ribbon 14 and wire 22 and the on/off cycle of the lamp, Fig. 5 (not shown) shows an alternative unit for the second unit, this alternative unit being similar to the first unit and Figs. 1, 2, 3 (not shown) show the physical construction of an assembly of the two units, resistor 34 and terminals 4, 6. A back stop (8c) for blade 12 acts as a noise maker for an audible signal. An electromagnet may be positioned adjacent arm 24 to provide snap action for the opening and closing of contacts 28, 30.

Title: Improvements in and relating to shutters
IPC: G03B9/50
Filed: 1930-10-31
Abstract: 365,224. Shutters. WILLIAMSON, C. M., Cascade Works, Litchneid Gardens, Willesden Green, London. Oct. 31, 1930, No. 32803. [Class 98 (i).] In a louvre shutter each blade is actuated bv a member which slidingly engages a surface either on or attached to the blade and traverses a path passing in close proximity to (but not through) the pivotal axis of the blade. In one construction the blades pivot either in the sides 12, Fig. 3, of the frame or in the ends of adjustable bolts 14. In the closed position the blades 1 rest on the corners 7, Fig. 1, of projections 6 on the frame. Each blade has an upstanding lug 3 which may be attached to the blade or stamped up. The lugs are engaged to open the shutter by a series of triggers 4, Fig. 4, on a slide 5. The blades may be spring-returned, or when the lugs are attached to the blades, returned by engagement of the triggers 4 with the surfaces 8 on the blades. Short additional triggers 9 on the slide 5 may be provided to hold the blades in the fully open and fully closed positions. The faces of the projections 6 may be shaped so that the blades in the open position are in convergent planes. In a modified construction, Fig. 8, the blades 1 (without lugs 3) are spring- returned and opened by a series of arms 4 on a shaft 16. This shaft may have a lateral reciprocating movement to and from the axes of the blades ; alternatively it may rotate either with a reciprocating or continuous movement.

Title: Engine hood or bonnet catches
IPC: E05B65/19
Filed: 1934-11-15
Abstract: 426,256. Fastenings. BASSICK CO., 38, Austin Street, Bridgeport, Connecticut, U.S.A. Nov. 15,1934, No. 32896. Convention date, April 9. [Class 44] A motor-car bonnet fastener consists of a catch lever forming an outside looped operating handle 24 and pivotally mounted at one end by a lateral shaft extension 26 which has a bearing in a plate frame 13, 14 secured to the bonnet 10, the other end of the lever being formed with an interior keeper-engaging lug 31 which is pressed upwardly into engagement with the keeper 34 by a spring 18 mounted on an extension 17 of the plate frame 13. The keeper-engaging lug 31 normally lies outward of the keeper 34 so that the handle 24 must first be pushed inwards to effect the engagement. By reason of the rigidity of the shaft extension 26 and the plate frame 13, the sheet metal of the bonnet is therefore slightly warped by such action and the resulting stress prevents lateral play.
