Filed: 1948-01-26
Abstract: 655,062. Treating wood. HUDSON, M. S. Jan. 26, 1948, No. 2257. Convention date, March 19, 1940. [Class 140] [Also in Group XIII] In a method of drying and impregnating wood or wood products by distilling off the water in a chamber by an atmosphere of vapours of higher boiling point than water, the drying medium is the vapour-phase of an aliphatic, naphthenic or aromatic compound inert to the wood and having a melting-point not greater than 60‹ C., the vapour phase being maintained at a temperature equal to the boiling-point of its liquid phase at the pressure in the chamber and the distilled water vapour being continuously drawn off. The wood is supported on a truck 32 in a chamber 10 having hinged ends 11, 12 and a receptacle 13 for the liquid treating medium M. An outlet 14 connected to a vapour collecting header 20 leads to condensers 15, 16 which in turn lead to a separator 18, the pipe 19 being a return pipe for the treating medium and the water going to waste at 19<SP>1</SP>. The treating liquid M which may be a coal-tar or petroleum fraction or creosote &c. is heated to its boiling point by coils 21 immersed in the liquid. Water is distilled from the wood and passes with the vapours into the condensers and separator, the condensed vapours returning to the chamber to be used again. A pipe 17 may be connected to a vacuum producing means to remove the vapours from the chamber when drying is complete and recover distillate which may remain in the wood. The wood is impregnated by filling the chamber 10 with preservative, which may be the same as the drying medium, and impressing a pressure on the liquid.

Abstract: 662,451. Centrifugal-separators. AKTIEBOLAGET SEPARATOR. Jan. 27, 1949. [Jan. 30, 1948] No. 2285/49. Class 23. In a centrifugal separator for liquids, sludge openings 7 are closed by a piston 8 moved by an auxiliary fluid introduced into a chamber 9, and discharge passages 14 from the chamber are closed by valves connected to an annular slide 17. The fluid is supplied to the chamber by means of passages 12, 13, a second chamber 11, and nozzles 10. When it is desired to discharge sludge, excess of fluid is supplied to the chamber 11 to overflow into a passage 24 to feed a further chamber 18. The centrifugal pressure of the fluid in the chamber 18 urges the slide 17 against springs 19 to open the passages 14. The fluid from the chamber 9 is discharged through a nozzle 22 and an overflow 23, As the nozzles 10 have less area than the passages 14, the chamber 9 empties and draws the piston 8 downwardly. When the openings 7 are to be closed, the supply of auxiliary fluid is cut off, and the springs return the slide 17 to close the passages 14. Fluid is then supplied to the chamber 9 to move the piston 8 to close the openings 7. The slide 17 may be closed by mechanical or electromagnetic means, and the chamber 11 may be located at the bottom of the bowl to permit supply of auxiliary fluid by an external pipe. The Specification as open to inspection under Sect. 91 states that the slide 17 may be replaced by separate pistons for each passage 14. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in optical systems for television and the like
IPC: H04N3/08
Filed: 1934-01-23
Abstract: 433,945. Television. SCOPHONY, Ltd., 2, Dean Street, Soho, London, and JEFFREE, J. H., 6, Monkey Island Lane, Bray-on-Thames. Jan. 23, 1934, No. 2399. [Class 40 (iii)] A beam of light is given one component of scanning in the direction of smaller " light grasp," this movement is changed into one in the direction of larger " light grasp," and the beam is then given the other component of scanning. The " light grasp " in any direction is defined as the angle of divergence (or convergence) of the beam in that direction multiplied by the width of the entrance (or exit) pupil in that direction. Light from a source 1, Fig. 2, passes through a cylindrical lens 4 and falls on a rotating drum 5 having polished metal rods 7 round its periphery. The reflected beam 9 oscillates in the direction of its smaller " light grasp" c and is incident at an angle of 45 on a number of reversing prisms 11. The emergent beam, whose direction of movement has been changed by the prisms 11 to that of the arrow c, is focused by the cylindrical lens 18 onto the screen 17 and is given the other scanning component by a mirror drum 13. The prisms 11 may be replaced by cylindrical lenses. In a modification, the beam 9 Fig. 10 falls on a series of refracting rods 29, which change the direction of the smaller " light grasp " without changing the direction of movement b. The direction of movement and the direction of smaller "light grasp" may be changed in opposite senses by stepped mirrors, Figs. 13, 14 (not shown), and the lens 18, Fig. 2, may be removed and the beam effectively focused by twisting the lens 4 to be at an angle with the rods 7, Fig. 9 (not shown). Scanning may be effected by cylindrical lenses in place of the rods 7 or by oscillating mirrors. The source 1 may be modulated for synthesis, or unmodulated for spot-light scanning or may be replaced by a cell for flood-light scanning. Specification 328,286, [Class 40 (iii)], is referred to.
