[Class 52 (ii).] A couch bed comprises a main bed section and a movable bed' section which can be moved horizontally under and out from under the main bed section, and legs pivoted at the corners of the movable bed section operatively connected with a lever so as to move the movable bed section vertically to and from the level of the main bed sections. The main bed section 2 comprises end frames 4, 4<1> connected by side bars 6, 6<1> and cross straps 7 to support upholstery springs, whilst the sliding sections 3 has end bars 13, 14 connected by bars 15, 16 and also transverse rods 17, 18 which are pivotally supported and carry the floor engaging legs, e.g. 19, 20. The sliding section is guided in its movements by brackets 34<1> having bifurcated ears 35, 36 which slide along or engage with the angle irons of the stationary frame, a slot 37 permitting change from horizontal to vertical movement. Cross straps 23, 24 connecting the side bars of the main and movable bed section control and guide the closing or nesting of the two sections. The elevation and lowering of the sliding section is achieved by a lever 38 which mav form an end rest and which is pivoted at 41 to a long link 40, this link being interconnected at 42, and by means of arms 43, 45, with the cross rods 17, 18 which carry the legs of the sliding section so that movement of the lever 38 in a clockwise direction rotates the cross rods and the legs engage the floor to raise the section to the level of the main bed. The sections are locked in the raised position by means of coiled springs 51 exerting pull on bent links 52 pivoted to the legs, by toes 49 engaging the underside of bars 15, 16, and by allowing the pivot 41 to move over the dead centre.

Title: Spectrometer
IPC: G01J3/08
Filed: 1960-05-24
Abstract: 958,957. Spectrometers. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. May 24, 1960 [May 27, 1959; April 20, 1960], No.18236/60. Heading G1A. [Also in Division G2] The spectrometer has an entry grid G in the focal plane of a collimator C, the radiation being dispersed at D before passing to a lens C<SP>1</SP> having in its focal plane F<SP>1</SP> an out-put grid G<SP>1</SP>. Each grid consists as shown in Fig. 2, of alternating opaque strips p 1 , p 2 ..p n  and transparent strips V 1 , V 2  . . . V n , the edges of each strip extending perpendicularly to the dispersion plane. The total area of the transparent strips is the same as that of the opaque strips, the strips of each grid being so distributed that for example the distance X n  of the n. th. strip from one edge b o  of the grid is given by the formula x n <SP>2</SP> = nx 1 <SP>2</SP>, where x 1  is the distance of the inner edge b 1  of the second strip from the same edge b o  of the grid. The opaque strips of the output grid may be reflecting. With this arrangement the lenses C, C<SP>1</SP> will, for radiation of one wavelength corresponding to the position of the dispersive system D, image the grid G exactly upon the grid G<SP>1</SP> so that all the radiation of this wavelength which is transmitted by the grid G will also be transmitted by the grid G<SP>1</SP>. The image of each transparent strip in the grid G will, in radiation of another wavelength, be formed at a position offset from the corresponding transparent strip of the grid G<SP>1</SP> so that some of this radiation will be reflected by the grid G<SP>1</SP>. The radiation transmitted by both grids is fed to a radiation detector and the radiation reflected by the output grid is fed to another detector and the intensities of the two beams are then compared. Each grid may be of square, rectangular, triangular or lozenge form or be formed by an annular sector (Fig. 30, not shown). Instead of two detectors, a differential pick-up may receive both beams. In other forms, (1) the input grid is made up of two grid members which are made alternatively operable either by moving the inoperable member out of the radiation path (Fig. 21 not shown) or by using a rotatable chopper (Figs. 24, 25 not shown); (2) the opaque strips of the input grid are reflecting and a chopper is arranged so that radiation is incident alternately on the transparent and reflecting strips (Fig. 19, not shown).

Title: Improvements in Processes for Softening Water.
Inventor: UECKE GEORGE HENRY
IPC: B01J49/00
Filed: 1917-12-13
Abstract: 120,293. Uecke, G. H. Dec 13, 1917. Purifying liquids.-In regenerating zeolite or similarly acting substances after being used for filtering and softening water, by passing upwards through it a current of brine or other regenerating solution, the brine which remains in the filter is drawn off downwards and stored for re-use. Preferably, a current of weak brine followed by a current of stronger brine is used. A filter 3 consisting of a closed tank having a bed of zeolite y and in some cases a bed y<2> of filtering material such as marble chips is supplied with water through a pipe 6, meter 7, and U-tube 8 having four cocks, two of which, 15, 18, are open during the filtering. The water passes up the pipe 9 downwards through the filter, up the pipe 12 to a discharge pipe 19. The filter may be cleansed by reverse flow by opening the cocks 16, 17. For regenerating the zeolite, brine is admitted to the base of the filter from brine tanks 24, 25 through narrow tubes 32, 33 containing non-return valves 37. Liquid is discharged by siphonic action through a perforated ring 21 immediately above the bed of zeolite, leading to a pipe 20, which is about the same diameter as the pipes 32, 33. The contents of the upper tank 25 consisting of weaker brine percolate upwards through the zeolite and afterwards the contents of the lower tank. Water is then admitted to the upper part of the filter. The lower part of the column of water above the zeolite is allowed to flow through the pipe 20 which is then closed, and brine from the base of the filter is allowed to flow through pipes 26, 27 first into the lower tank 24 and then into the upper tank 25. To remove final traces of brine from the filter, a cock 14 leading to a drain is opened. Regenerating salt is added to the tank 24 to restore the strength of the solution. When an open filtering tank is used, the brine tanks 24, 25 are placed at a higher level, and brine is returned to them by a pump. Specification 120,294 is referred to.

Patent GB-864488-A (GB)
Title: Synthetic bast of linear polymeric thermoplastic material
Inventor: STUDER MARTIN
IPC: B29C48/05
Filed: 1958-06-11
Abstract: <PICT:0864488/IV (a)/1> A synthetic bast-like material consisting of a flat, irregularly folded and at least partly agglutinated tubular filament is made by extruding a molten linear high polymeric thermoplastic material through an annular orifice in a spinneret, maintaining a slight superatmospheric gas pressure inside the tubular filament so formed, passing the filament, while still not completely hardened, through a cooling liquid and round a deflector therein, so as to flatten it, and withdrawing the filament under tension. Preferably the polymeric thermoplastic material melts between 100 DEG -300 DEG C. and is a polyamide or polyester.  As shown, a spinneret 1 having an annular orifice 2 is fitted with a gas supply pipe 3 through which an inert gas, e.g. nitrogen, can be fed into the emerging tubular filament 4, which passes into cooling bath 5 and then under deflector rod 6 and over rod 7, being thereby flattened and folded by the action of the withdrawal tension exerted by the driven rollers 8.  The filament is then stretched, preferably continuously with the spinning process, or subsequently as a separate process, in known manner, and wound up. The melt may be pigmented, or the final product may be dyed.  The Provisional Specification refers also to the use, as a deflector, of a narrow passage exerting a squeezing and folding action on the tubular filament, or of a pair of rollers so constructed that irregular folding and creasing take place.  Specification 533,307 is referred to.

Abstract: 691,748. Making cutlery blades. OMES, Ltd. July 23, 1951 [July 27, 1950], No. 18830/50. Classes 83 (ii) and 83 (iv). In a process for making knives from sheet - metal blanks comprising upsetting by end pressure to form a bolster, the tang portion of the blank is originally made broader than the breadth of the tang eventually required, and is thickened by lateral compression. A stainless steel blank 40 is upset to form a bolster portion 43 in an electrical upsetting machine, Fig. 1. The bolster is finished in dies, the flash trimmed off and the tang portion 41 is compressed edgewise to a thickened and rounded section 50. Alternatively the thickening up and rounding of the tang may be carried out before the bolster is upset. The work-piece is then finished as usual. The upsetting machine comprises spaced, hydraulically-operated vice electrodes 19, 21 and 20, 22, between which the blank is supported and heated. The end of the blade portion, extending into a rest 30 is engaged by a rod 33 carried on a hydraulic ram 28, which forces the blade to slide through the vice jaws 19, 21, causing the upset 43. Hydraulic cylinder and ram 27, 29 enables the upset to be controlled by allowing the vice jaws 20, 22 and tang portion 41 to recede gradually from the jaws 19, 21 during the upsetting. A rod 34 on the ram 29 backs up the tang portion. Nuts 35, 36 limit the travel of the rams.

Title: Web tension control apparatus
IPC: B29C53/32
Filed: 1955-06-29
Abstract: 777,785. Winding webs. GENERAL ANILINE & FILM CORPORATION. June 29, 1955 [July 1, 1954], No. 18848/55. Class 100(1) A web tension control apparatus for web material wound from a supply roll over a plurality of rollers on to a take-up roll, comprises a dangle roller around which the material is looped, means for controlling, the winding speed in accordance with the position of the roller, adjustable means for varying the effective weight. of the roller thereby predetermining the web tension at the commencement of winding, and means for automatically altering the effective weight of the roller during winding upon a change in the position thereof. Web material is fed by a roller 18 driven by a motor 19 to a weighted dancer roller 10 supported in arms 21, 22 fixed to a shaft 23 and is wound on a take-up roller 11. The speed of the take-up roller 11 is controlled by the position of the roller 10 through linkages 25, 26 and a shaft 27 which actuates the speed control 28 of an electric motor 29 driving the roller 11. The shaft 23 carries an arm 37 having a slidable counterweight 38 and a liquid container 39 attached by brackets 40, 41. In operation, the loop of web around the roller 10 is adjusted in length for a desired tension by moving the counter weight 38 in the appropriate direction. As winding proceeds, the diameter of the roll being wound on roller 11 increases, the loop shortens thus causing, through the speed control 28, a decrease in speed of the motor 29 and roller 11. Shortening of the loop causes rocking of the arm 37, thus causing liauid to flow from one end of the container 39 to the other to transfer its weight from the roller 10 to the counterweight 38. By suitable choice of liquid and volume of the container the web tension may follow a required law. The container 39 may have perforated baffles through which the liquid flows. In a modification Figs. 5 and 6 (not shown) the liquid passes from one vessel to another via a pipe, both vessels being suspended from the arm 37. Alternatively, the arm 37 may be hollow to accommodate the liquid.

Air-heating furnaces.-In air-heating stoves of the kind in which the furnace gases pass through or between a plurality of separated flues, between or through which the air to be heated passes, the rows of tubes are arranged in heating chambers so as to form isolated flues, the tubes being supported so as to permit of independent expansion and contraction. In the form illustrated in Figs. 2 and 3, the stove has a central fireplace 1 and air-heating chambers 2 on each side through which the furnace gases pass. The lower tubeplate 6, supported by members 8 and 11, is made in one piece with flanges 22 forming elongated chambers, within which are orifices 23 corresponding with the tubes, the space between tubes and flange being packed with red lead, asbestos &c. to form a smoke-tight joint. The upper tubeplate 5 is made up of cast-iron sections, and has semi-circular pockets 29 to receive the tubes, packing again being used. The tube-plates 5, 6 support the tubes with sufficient freedom to allow independent expansion and contraction. The air tubes 7 are arranged in rows, between which are flues 16. Air enters the tubes by apertures 12, 23 and is delivered into the chamber 30. The flues 16 have inlet ports 20 and outlets ports 18 for furnace gases, the outlet being into the main smoke flue 17. Baffle plates 21 or extensions of the firebrick lining 3 protect the tubes adjacent to the furnace. Auxiliary air heating chambers 30<a> may be formed as jackets, air entering through valve controlled ports 34 and passing through ports 35 to the hot air chamber 30. The flues may be formed by rows of tubes joined by plates, and the shape of such rows of tubes may be circular, oval, rectangular, &c. For small units, the tubes in each element may be welded or brazed together, or may be cast together with a header at the top and bottom. The air-tubes may be formed of corrugated plates bolted together to form conduits between them. The upper plate may be formed in one piece. A form of tube having flat sides is shown in Fig. 17. Fig. 29 shows a modification in which oil or pulverized fuel is used. The fireplace is replaced by a casting 36 forming an air-heating passage 37, through which air passes to the back'of the stove and the chamber 30. The air-supply to the oil burner 40 is preheated, a part 42<a> of the air supply pipe 42 passing through the hot air chamber 30. A safety valve 43 permits the escape of gases if explosion occurs.
