Title: Improvements in apparatus for deseeding flax
IPC: D01B1/12
Filed: 1920-08-13
Abstract: 167,962. Allen, F. L. van. Aug. 13, 1920. Rippling - apparatus; grip-chain and like arrangements for feeding, holding, and conveying fibrous materials.-The seeds are removed from flax straws, whether harvested in sheaves, or raked and forked as hay, by a large conveying-drum co-operating with a number of independently movable rollers yieldingly held against its surface. A machine for dealing with flax taken from sheaves comprises a drum B, deseeding-rollers C, and holding and conveying belts D, E. The root end of the flax is laid on the belt E and supported by a table 26. It is gripped between the belts, which run over part of the drum 13 and over suitable guide-pulleys 17 and tightening-pulleys 20, 22. The seed ends are carried over the surface of the drum B and are acted upon by the rollers C carried by arms 11 pivoted on rods 12 and pressed against the drum by springs. There are a number of rollers arranged on each rod, and they are mounted in staggered relationship with the adjacent sets. The flax is then delivered on to a table 40<a> and beaten bv rods 41. The seed is finally shaken out of the flax by passing it between two sets of beaters 44, 45, 46, 47, adjacent beaters in one set moving in opposite directions but parallel to the corresponding beaters in the other sets. The seed falls on to a reciprocating sieve 48 and through it into a hopper 54. Seed &c. from the first of the deseeding rollers falls into a shoot 52 and is passed between spaced apart spring-pressed rollers 50 on to a reciprocating deck 49 which passes it on to the sieve 48. In a machine for deseeding flax which has not been arranged in sheaves, the travelling belts are dispensed with and the deseeding rollers are arranged across the full width of the drum B. The deseeded stalks are delivered on to decks or racks, where they are shaken to release the seeds.

IPC: G03B42/04
Filed: 1958-07-23
Abstract: 858,688. X-ray film cassettes. REDMAYNE & SONS Ltd., S. June 17, 1959 [July 23, 1958], No. 23748/58. Class 98(1) An X-ray film cassette comprises a flat flexible sleeve slidably receiving a flat flexible strip, adapted to carry an X-ray film, which may be drawn into the sleeve until abutment of suitably positioned stops locates the film within the sleeve in the correct position for exposure. Referring to Fig. 1, the sleeve 5 and strip 6 which, for example, are of heavy black polyvinyl chloride, have abutting shoulders at 9 to locate in exposure position the film which lies beneath the flap 13 of the slidable strip. The strip and the flap are provided with lead foil which sandwiches the film. The projecting ends of the strip 6 are folded back over the sleeve where they are secured by lateral flap extensions 7, 8 of the sleeve which fold cross-wise over them and are secured by pressfasteners. The film is withdrawn after exposure by pulling the strip in a direction opposite to that of its insertion. Complete withdrawal is prevented by the tag 11.

Title: Method and apparatus for saline water conversion
Inventor: LICHTENSTEIN JOSEPH
IPC: C02F1/10
Filed: 1964-06-09
Abstract: 1,038,393. Distilling sea water. SALINE WATER CONVERSION CORPORATION. June 9, 1964, No. 23791/64. Heading B1B. Saline water is converted to fresh water by heating the saline water at a heat source 14 and then bringing it within a tower 17 into contact with a counterflowing, gas at sub-atmospheric pressure and at a lower temperature than the saline water so that the gas becomes humidified, and then drawing the humidified gas by a fan 21 into a superposed tower 20 for contact with cooler fresh water so effecting dehumidification of the gas and thus obtaining additional fresh water which is drawn off through pipes 24, 25. Unused saline water is returned to the heat source which may be a condenser and the fresh water is delivered after use through pipe 26 to a heat exchange unit for cooling by unheated saline water and recirculation. The towers are supported within a casing 31 and each tower comprises an outer annular trough 129 (Fig. 2, not shown), intermediate troughs 130 and distributing channels. In both towers water fed to the main trough flows to intermediate troughs and distributing channels from which it overflows running down the sides of the plates 132 therebeneath as a film for contact with the gas. Unused water is collected in a trough 135 in communication with a return trough 136. Air may be used as the gas.

Title: Improvements in and relating to water-cooling radiators for internal combustion engines
IPC: F01P7/12
Filed: 1927-09-12
Abstract: 300,345. Miller, F. W. Sept. 12, 1927. Thermostats. - Bi-metallic strips controlling air-admission shutters 40, Fig. 1, of engine radiators are arranged externally, of a metal chamber or conduit included in the water system between the engine 1 and the radiator 2. The metal chamber may consist of a box-like member 3, Figs. 2 and 3, having branches 4, 5 connected by flexible hose pipes 6, 7, Fig. 1, to the engine and radiator, and the bi-metallic strip 14 is housed in a metal casing 8 in contact with the member 3. Preferably two strips and casings are employed as shown, the strips being secured at one end by screws 15 to their casings, with their free ends bearing on arms 16 coupled together outside the casings by a rod 29, which is connected by a chain &c. 34, Fig. 1, to the uppermost shutter arm 39. A volute spring 19 in each casing 8 is secured to a pin 18 on the arm 16 and to a central drum 20, which is secured to the cover 21 of the casing. This cover may be rotated to adjust the spring tension, and be retained in adjusted position by a screw 25 passing through one of several holes 26, Fig. 1, in the cover and entering a lug 27 fixed to the casing wall. The casings are secured to the water chamber by studs 9, Fig. 3, forming pivots for the arms 16, and their covers are clamped by nuts 22 on studs 23 screwed into the ends of studs 9. The chain &c. 34 is adjustably secured to the rod 29, and is guided by a member 35 and pulleys 36, 38. Preferably the shutters are normally held closed by a spring 41 and on rise of temperature the bimetallic strips contract and pull the chain against the action of the volute springs 19 and the spring 41, but as an alternative the shutters may be held open by a spring and closed by the thermostats; or the thermostats may expand when heated. The shutters may be clamped in the open position by holding the arms 16 in a retracted position by means of a slotted arcuate member 42, Fig. 2, having a projecting lug 43 in the slot 28 of the casing 8, and a clamping screw 45, 46. In a modification the water box is placed close to the radiator header, and the thermostat casings are clamped thereto by a central sleeve forming a bearing for a shaft connecting the two arms 16, which do not project outside the casings. Only one volute spring is employed, and the shutter is actuated by a chain adjustably connected to an external arm on the central shaft.

Filed: 1939-08-18
Abstract: 534,469. Aero-engine accessories. COWDREY, C. L. Aug 18, 1939, No. 23914. [Class 4] An aircraft engine cowling which is otherwise sealed at the bulkhead and behind the airscrew has an air inlet conduit which diverges rearwardly into the cowling, separate passages being formed within the cowling with their inlet ends open at appropriate points to the interior of the cowling and their outlet ends open to the outside of the cowling to provide a flow of air where it is required. Entrained matter such as snow and dust is deposited beyond the end of the conduit where it is innocuous. Fig. 1 shows a cowling 11 having an inlet 18 which diverges rearwardly towards a rear bulkhead 14. A radiator for cooling the engine-cooling liquid is mounted beneath the cowling and has a separate air entrance 17, and a rear exit controlled by a flap 25. An air inlet 21 with air filter opens within the cowling which is at a higher pressure than the external atmosphere. An electric generator or other accessory may be enclosed by a casing 26 having an inlet 27 and a conduit 29 leading to the atmosphere at 29. Short stub pipes 22 lead the exhaust gases into manifolds 24 partially housed in recesses 23 in the cowling, the holes in the cowling for the pipes 22 being airtight. In modifications, the radiator is disposed away from and behind the cowling and the exhaust gases discharge into a manifold surrounded by a conduit within the cowling and open at the rear end, the conduit and the enclosed manifold passing through the cowling at its forward end and being bent rearwardly.
