Title: Method of production of artificial film from seaweed, and the like
IPC: C08L5/00
Filed: 1934-01-22
Abstract: A process for the production of films from brown alga and like seaweeds comprises the following steps.  The brown alga or the like is immersed in aqueous sodium carbonate, filtered, and to the viscous solution is added dilute acid.  The gelatinous substance is dissolved in a solution of alkali salt containing ammonia, filtered and reprecipitated and bleached, by adding a mixture of dilute hydrochloric and nitric acids.  The washed and dried material is then dissolved in a mixture of aqueous sodium carbonate and a product obtained by passing mixed vapours of alcohol and ketone produced by dry distillation of lime acetate over a heated mixture of nickel and calcium sulphide.  The solution, after maturing and diluting, is formed into films by coagulation in a bath containing caustic alkali and furfurol.ALSO:A process for the production of films from brown alga and like seaweeds comprises the following steps.

Title: Improvements in or relating to electrical resistance materials and resistors made therefrom
IPC: C03C4/00
Filed: 1967-01-17
Abstract: 1,136,336. Enamel or glass and metal mixtures. TRW Inc. 17 Jan., 1967 [1 Feb., 1966], No. 2497/67. Heading C1M. A vitreous enamel electrical resistor composition adapted for application to and firing on a substrate as a film consists of 50% to 95% by volume of glass frit and 50% to 5% by volume of a mixture of finely divided particles of a refractory metal nitride and finely divided particles of a refractory metal. The refractory metal may be titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, tungsten or molybdenum and the nitride a nitride of any of these. Any of the refractory metals may be used with its own nitride or a nitride of any of the others. The ratio of metal nitride to metal may be between 0À5 to 5 parts metal nitride to 1 part metal. The glass frits are preferably the borosilicate frits such as lead, bismuth, cadmium, barium, calcium or other alkaline earth borosilicate frits. To make the resistance material the glass frit, metal nitride and metal are broken down to particles below 2 microns in size and mixed together such as by ball milling in water or butyl carbitol acetate or a mixture of butyl carbitol acetate and toluol. The mixture is then adjusted to the correct viscosity for application to the substrate which is generally of ceramic such as glass, porcelain, steatite, barium titanate or alumina &c., by brushing, dipping, spraying, or screen stencil application. The coated substrate is fired in a conventional furnace preferably in an inert or reducing atmosphere. Small quantitites of clay may be added to the coating mixture to increase the firing temperature and thus give a greater resistance stability.

Title: Improvements in or relating to automatic reclosing circuit breaker systems & apparatus
IPC: H02H3/06
Filed: 1926-01-28
Abstract: 258,150. Igranic Electric Co., Ltd., (Automatic Reclosing Circuit Breaker Co.). Jan. 28, 1926. Cut - out arrangements. - In an automatically - reclosing circuit-breaker system, wherein when the circuit-breaker 4 is released by the opening of the overload relay 19 on overload a shunt resistance 16 is introduced to supply the load circuit 2 with a testing voltage, the circuit-breaker is reclosed automatically after a time-interval, if the overload disappears, but if the overload persists long enough to operate a thermal relay 15 the resetting circuits are maintained open and the shunt resistance disconnected until the thermally relay is manually reset. In opening, the circuit-breaker breaks its maintaining circuit at 9, 10, 11 and allows a switch 13 to fall, retarded by the dashpot 14, and complete the circuit of a reclosing relay 6. If the overload has gone, the relay 6 closes with the voltage supplied to the load circuit through the shunt resistance 16 and completes a reclosing circuit for the coil 5 through the thermal relay 15 and the reclosed overload relay 19. The switch 13 is mechanically opened by the closing movement of the circuit-breaker but, meanwhile, the retaining circuit, at the contacts 9, 10, 11 has been closed. If, however, the overload persists, the testing voltage across the load is inadequate to operate the relay 6, and the current through the shunt resistance 16 which passes also through the heating resistance 24 of the liquid-thermal relay heats up the liquid and, after an interval, opens the thermal relay thereby disconnecting all the resetting circuits as well as the resistance 16.

Title: Improvements in or relating to the manufacture of filter tips for cigarettes
IPC: A24D3/02
Filed: 1935-01-25
Abstract: 446,210. Cigarette-making machines. MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. Jan. 25, 1935, No. 2566. [Class 130] A filter tip or filling, produced by rolling strip material into a spiral plug, is, by continued or subsequent rolling between parallel surfaces, caused to envelop itself in a strip of wrapping material having a part or the whole of its surface coated with adhesive. As shown in Fig. 1, strips of material 1 are fed beneath a spring-loaded plate 3 on to a moving drum 2, preparatory to producing a spiral plug by fingers 8 which bring the edge of the strip into engagement with the roughened periphery of a resiliently mounted rotating roller 4 to turn over the leading edge of the strip against an inclined guiding means 3a. The means for forming the spiral plug are described in Specification 444,079. A web 10 of wrapping material is fed on to the concave sides 9a of a hexagonal drum 9 and cut into strips 11 by a reciprocating knife 12a operating in slots 9e in the drum. The web is pasted by a roller 13 or while it is on the drum, on which it is held by suction exerted through holes 9b, 9c. The drum 9 is rotated intermittently to position the surfaces 9a parallel to the periphery of the drum 2 and a member 9d reduces the suction applied to the wrapper strip 11 which is picked up by the rolled filling as it leaves a stationary rolling surface 7. The wrapped product is discharged into an inclined shoot. In modified constructions (1) the wrapper web is fed on to the concave sides of the drum 9 parallel to its axis, (2) the pasted wrapper strip 11 is carried into engagement with the trailing edge of the strip 1 of material from which the filter tip or filling is subsequently rolled, by suction holes provided in the drum 2 and controlled by a stationary cut-off member, (3) the filling is rolled in a rolling unit 16a ... e in which the roller 16c, which is opposite the inlet guide 20 and causes a preliminary bunching of the leading end of the strip 1, is carried by arms 18 which can be swung downwards about the axis of the roller 16d, while the rollers 16a, 16b are carried by a frame 17 which can be raised to permit the roller 16d to discharge the filling laterally. The filling passes between a guide 21 and a belt 23 passing over a drum 24 and is enveloped in a wrapper strip 11 supplied by a drum 9, and (4) the wrapper strip is supplied by an oscillating carrier which picks up a pasted strip in one position and carries it to another position where it is parallel with the surface of the drum 2.

Abstract: 326,294. Fitzpatrick, H. D., (Naamlooze Vennootschap Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). Jan. 25, 1929. Counter scales and the like; vibration-neutralizing.-In weighing-apparatus wherein parallel guiding means are provided for the platform or platforms, the parallel guiding means has incorporated therein or, connected therewith, resilient or other self-acting means whereby the error is prevented which results from the bending of the weighing mechanism arising from placing the load adjacent to one of the edges of the platform. As shown in Fig. 2, applied to an automatic scale, the check link 9, connected as usual to the check arm 7 is pivoted to one end of a spring a secured at its other end to the frame. When a load A is placed on the edge of the pan the check arm is bent, for example as indicated by dotted lines and the consequent error produced in the parallelogram is rectified by the flexing of the spring a. In a modification, shown in Fig. 3, applied to a semi-automatic scale, the check arm 6, 8 is formed with a right-angled extension c to the extreme end of which one end of the spring b is secured. The other end of the spring is secured to the ordinary shackle 17 engaging the check link 9. When a load is placed on the edge of the scale pan the bending of the check arm 6, 8 produces a flexing of the spring up or down so as to restore the linkage to a parallelogrammic shape, thus avoiding error due to the bending. The spring also prevents injury to the parallel guiding means by taking up shock.

Abstract: 1306036 Gauges employing movable feelers  SOC GENEVOISE D'INSTRUMENTS DE PHYSIQUE 19 Jan 1971 [16 Feb 1970] 2588/71 Heading G1M A probe or feeler 8 which may move axially and laterally is solid with a lever 11 which extends upwardly so that its end is acted upon by springs 16 fixed to a slide 17 adjustably by turning a screw 18. The lever 11 is flexibly attached at its bottom end to a vertical member 2 by means of L-shaped spring blades 12 and both the lever 11 and member 2 mount rollers 15 which co-operate with springs 14 fastened to 2 to allow 11 to move relative to the member 2 and to bias 8 to the position shown. The member 2 is connected to a fixed member 4 by four spring blades 3 to form a parallelogram linkage. Movement of the probe 8 upwards causes 2 and 11 to move upwardly together to flex springs 3 and operate an electronic detector 1, whilst transverse movement alone by 8 causes 2 and 11 to flex apart on their hinge springs 12 to operate electronic detector 13, the detectors thus signalling the degree and direction of movement. A screw 9 bearing in the body 4 contacts and causes friction with the member 2 and renders the parallelogram rigid and suppresses the axial sensibility of the feeler 8. Springs 6 attached at their inner ends to an eccentric 5 are adjustable by rotating a knob 7 and serve to increase or decrease the downward force on the probe 8.

Title: Improvements in or relating to a device for aligning an endless belt conveyor
IPC: B65G39/16
Filed: 1956-01-27
Abstract: 821,433. Maintaining alignment of conveyer belts; mechanical projectors. STEPHENSADAMSON MFG. CO. Jan. 27, 1956 [April 11, 1955], No. 2724/56. Class 78 (1). A device for aligning an endless conveyer belt comprises a roller engaging the belt, the roller being rotatably mounted between a pair of levers pivoted at one of their ends about axes which converge in the direction of movement of the portion of the belt engaging the roller, and means on each side of the roller adapted to be engaged by the conveyer belt on lateral drift thereof to swing the levers in the direction of drift. In one form, Fig. 1, the belt 12 on its return run engages a roller 24 which is journalled in self-aligning bearings 26 carried by a pair of arms 16 pivoted on pins 18. The pins are carried by a base 20 so as to be oblique to the direction of movement of the belt and to lie in a plane at an angle midway between the planes of the entering and leaving portions 28, 30 of the belt with respect to the roller, and are furthermore arranged so that in normal operating position the arms 16 extend in vertical planes and each bisects the angle between the entering and leaving portions 28, 30 of the belt. The upper ends of arms 16 carry rollers 32 engaging the edges of the belt, whereby drift of the belt causes pivoting of arms 16 from their normal positions. This causes the roller to move laterally and simultaneously tilt in a direction to restore the alignment of the belt. As applied to a mechanical projector, Fig. 6, employing a belt 38 passed around rollers 40, 42 and a pair of discs 44 between which material is fed through a shoot 50, the discs 44 are journalled in self-aligning bearings 58 in arms 50 pivoted on oblique axes 52 and carrying rollers 62 engaging the belt edges. Roller 42 is mounted adjustably on a pair of arms 66 to maintain tension in the belt and allow the direction of delivery to be adjusted.

Title: Improvements in or relating to methods of effecting the evaporation of water or solvents from liquids in bulk
IPC: B01D3/00
Filed: 1944-02-16
Abstract: <PICT:0582575/III/1> <PICT:0582575/III/2> Water or other solvents are evaporated from solutions of heat sensitive substances, e.g., blood, vitamins, enzymes, by subjecting the liquid to the heating action of a high frequency electric field while it is contained in a vessel or conveyed by a tube connected to a source of vacuum.  In Fig. 1, the liquid to be evaporated is fed from a vessel a into a vessel c, surrounded by a copper coil carrying a high frequency current, and connected to a source of vacuum via an entrainment separator f, condenser h and receivers g, j.  In Fig. 4, the liquid is drawn upwards from the feed vessel a into the tube c which contains a straight metallic member d encased in glass and carrying the high frequency current. The arrangement may be such that a full flow of liquid is maintained in the tube c followed by flash distillation in the vessel f.  Alternatively, the rate of feed may be so adjusted by valve b that vaporisation occurs in tube c and liquid and vapour pass up it under the influence of the climbing film effect.  In either case concentrated liquid is collected in receiver g.  In an example, the mixed solvents were evaporated from a 30 per cent. solution of vitamin C in aqueous methanol under 28 inch vacuum. Maximum temperature recorded was 40 DEG C.  In another example, the addition of 1 per cent. of common salt to a 33 per cent. solution of dextrin in water increased the rate of evaporation three times. Specifications 563,440 and 563,590, [both in Group XI], are referred to.
