Title: Method of preparing stable emulsions
IPC: D21H17/60
Filed: 1936-06-12
Abstract: A stable aqueous waxy emulsion is prepared by adding a liquid waxy material, e.g. mineral, animal or vegetable materials which are liquid at room temperatures or solids melting up to 170 DEG  F., such as paraffin wax, or asphalts, to an aqueous alkaline solution containing a water insoluble acid precipitatable protein and an emulsifying agent, 1-2 parts of the protein being used with 4 parts of the waxy material to prevent agglomeration of the particles of the waxy material when precipitated by setting of the emulsion or by evaporation.  The amount of emulsifying agent is about one-eighth of the amount of waxy material employed. Suitable proteins include casein from milk or the soya bean, or proteins obtained from peanuts, linseed and other seeds, or maize. Suitable emulsifying agents comprise ammonium oleate, turkey red oil, soaps, sulphonated oils, triethanolamine or gums such as gum arabic.  The alkaline materials may comprise caustic soda, sodium carbonate, ammonia, borax, sodium silicate or di-sodium phosphate. The emulsion is used to confer grease and waterproofness, particularly to paper and paper products, and is preferably broken by means of an acidic material such as alum, or by evaporation. Advantageously, the treated product is treated with a hardening agent for the protein, such as formaldehyde.  The emulsion may be applied to paper products in various ways using standard equipment, e.g. to the paper pulp after which the emulsion is set by means of alum, and then if desired, a filler such as an alkaline-earth carbonate or other ingredients may be added; to the web in a size press on a paper machine; in water boxes in the case of a board machine after the sheet has been formed and dried; or by applying the emulsion at the wet end of a paper machine by means of rolls or sprays.  Finished papers, such as wallpapers, may be waterproofed.  A rosin-sized paper containing an alkaline earth filler may be obtained by first treating the filler with the above emulsion and setting it by means of alum, whereby the filler particles are enclosed in a film of, for example, paraffin, and then adding to rosin-sized paper pulp.  The products may also be used for the waterproofing of textiles, felt, fur, hair, straw or feathers; cement, stucco, plaster; leather, board or lumber.  The emulsion is after set by means of alum and the protein hardened by formaldehyde.

Abstract: 376,452. Stays ; pinless hinges. COX, R. W., 135, Lower Richmond Road, Putney, London. June 6, 1931, No. 16611. [Classes 65 (i) and 65 (ii).] A stay for vehicle windscreens or other hinged members is constructed so as to be flexible in one direction and rigid in the opposite direction ; it may be formed as a chain of which the links have projections preventing flexure in one direction. As shown in the Figure a chain is used, comprising links pivoted together at b and having abutments c which prevent bending upwards. The screen is hinged at the top edge in the manner shown, and the stay chain is attached to the lower edge and passes through a guide e which bends it so that the free part is under the facia board out of the way. In the arrangement shown, the chain passes round a sprocket wheel h in the guide, rotatable by a worm gear from a, handle in the vehicle to open or close the screen. The Provisional Specification describes the following modifications: The stay may comprise a flexible metal or other strip having abutment pieces along one side to prevent bending towards that side. The operating gear may be dispensed with, the chain being used purely as a stay and being held in any position by a clamping screw or other means ; in thise case a roller may be substituted for the sprocket wheel h. The securing means may comprise a spring-pressed ball or detent, or a rotatable cam; the cam preferably acts to exert an endwise pull when engaging the chain, so as to pull the screen tightly on to its seating when closed. A spring catch may be used to hold the chain while the normal securing means is temporarily released.

Title: An improved process and apparatus for the reduction of grain and its subsequent conversion into bread or like product
IPC: A01C1/02
Filed: 1928-06-08
Abstract: 317,571. Rabinowitsch, E. June 8, 1928. Reduction processes; treatment by damping; treating with air; treating with solid substances.- Dry cleansed grain is washed for from one half to three-quarters of an hour in an eight per cent solution of sulphuric acid. It is then placed on a perforated shelf or net B in a tank A, and after washing in running water to remove the sulphuric acid is allowed to steep for about twenty-four hours. The grain is then continuously wetted by water from a pipe system F and is also continuously aerated by air drawn through the apparatus by an air exhaust at the end of a pipe E. The grain germinates and salt, limewater, and glycerine are added in small proportions to prevent decomposition, the mixture being taken to a mixing machine where it is worked into a coarse dough. Ungerminated substance rich in protein, such as bran, may be mixed in the dough. The prepared dough is transferred to an insulated cylinder A fitted with a hermetically sealing lid F and a piston 0 adapted to be depressed on to the surface of the dough by a worm gear. The dough ferments at a temperature of about 30-35‹ C. for from twelve to fourteen hours, the pressure in the cylinder rising during the process. When the fermentation is complete the upper part of the cylinder is evacuated and the piston suddenly released. The sudden release of pressure ca.uses disintegration of the cellular structure of the grain. The dough is then extruded through the bottom of the cylinder, kneaded with yeast and baked into bread.

Title: Current limiting circuit breaker
IPC: H01H9/42
Filed: 1975-04-23
Abstract: 1511881 Automatic circuit-breakers; electromagnetically operable switches SQUARE D CO 23 April 1975 [29 April 1974 (6)] 16721/75 Heading H1N An automatic circuit breaker is combined with a series current limiting electromagnetic switch in a single mounted two parts housing for the three phase switch. In each phase compartment 44, 45, 46 of the housing a resiliently mounted fixed contact assembly 50 is connected to terminal 60 and has main and arcing contacts 53, 54 co-operating with a movable contact 70 in region surrounded by a magnetic plate structure 130 adjacent a arc shoot 133. The movable contact is on a lever 67 coupled to a bar 63 common to the three phases and operable by toggle links mechanism 73 which includes a latch lever 76 retained by engagement in the centre phase armature of an adjustable overload electromagnet 111. The armature of the overload electromagnets 111 are all connected to a common bar 118 which is also movable by a lever 106 when the latter is released by a common thermal trip bar 105 acted upon by the phase bimetal strips 145. The bar 108 may be moved to the trip position by a manually operable push-button (Fig. 34, not shown). Current is carried from the movable contact lever by a flexible connector to a bar 133 on which the bimetal 145 is mounted and which connects to a conductor 142 coupled by a screw 146 to a part 148a of an approximately box-shaped structure 148 arranged in relation to a yoke 156 so that current passes along part 148a and the box sides to a part 150 in parallel with current in a part 150alpha. The current then passes through normally closed contacts 153, 155 on arms 152, 154 pivoted respectively at 168 and 170. On very heavy overload (e.g. 1000 amps) sufficient current will flow in part 148alpha for a biased armature 158 to be attracted to the yoke 156 so that a link 164 is moved upward and a pin 166 thereon rotates arm 152 about its pivot 168 and a further pin 167 is moved to permit arm 154 to move under the repulsion forces of the currents in the two arms 152, 154. As the contacts open within a rectangular magnetic yoke 182, which assists movement of the arc between contacts 153, 155 towards an arc chute 202 current passes in parallel with the arc along conductor 188b (assisting the effect of current in part 148a), conductor 188d (assisting in the magnetization of yoke 182), a connector 190 and through a positive temperature coefficient resistor 192 embedded in ceramic compound in a recess 45alpha in the moulded base 41. The other end of the resistor 192 is connected through a conductor 199 (which also passes through the yoke 182) to the same terminal member 184 as a flexible connector 178 coupled to the arm 154. Features of the combined breaker and switch are claimed in divisional Specifications 1,511,882, 1,511,883, 1,511,884, 1,511,885 and 1,511,886.
