Abstract: 735,675. Endless chain conveyers. FORSTERS MACHINE CO., Ltd. April 9, 1954 [April 14, 1953], No. 10200/53. Class 78 (1). In a conveyer comprising one or more fingers 23 carried by endless chains 3 and adapted to move over an article-supporting surface 1 to push the article forwards, to stop, to be moved rearwardly clear of the article and then to be further moved by the chains in a return path clear of a following article, the fingers are guided in a curved path over the whole or a part of their movement. As shown, each finger is mounted on a carrier consisting of two side members the rear parts 17 of which are of channel form for slidingly engaging following pins 20 on the chains 3 while the front parts are secured to blocks 16 recessed to receive pivotally leading pins 15 carried by plates 14 secured to the chains. A cross bar 19 connecting the side members carries the finger 23. Chains 3 are guided between plates 6 and 7 first along a straight path and then along a curved path to the delivery end of the conveyer, where the chains pass round sprockets 8, 9, 12 and 13. Pins 15 are arranged to coincide with the axis of sprockets 8 whilst the plates 14 pass around the latter so that a dwell is obtained, after which the carrier is reversed for a short distance as plates 14 pass to sprockets 9, the carrier finally being withdrawn as plates 14 pass around sprockets 12 and 13 along a return path. To control the movements of the carrier, a roller 24 arranged on one member 17 in transverse alignment or slightly rearwardly of pins 20 engages a track 26 parallel with rails 4 and 5 and concentric with or slightly more curved than rails 6 and 7. An upper rail 33 is arranged above an opening 34 in the guide. At the delivery end roller 24 passes beyond the opening, dwells, and returns over the opening and then passes through it. A second roller 25 at the rear end of the other member 17 engages a track 27 which is curved more sharply than the track 26. At the delivery end roller 25 dwells, returns a short distance, then traverses an arc above the track 26 before passing under the end of the track as the carrier is withdrawn. Specifications 645,418, 668,230, 712,829 and 733,654 are referred to.

Title: Method and apparatus for displaying image and measuring object therein
IPC: G01S11/12
Filed: 1971-04-21
Abstract: 1320304 Television HAMAMATSU TV CO Ltd 21 April 1971 [24 April 1970] 10441/71 Heading H4F The scanning of an optical image formed at camera tube B (Fig. 2) includes, during each line flyback period of a "normal" full-image scan, a further scan of a small sub-area of the image. As described, the sub-area is centred on a point of maximum luminance, the X and Y co-ordinates of which are derived by circuits X 0 , Y 0  and fed to external measuring or control circuits at line rather than frame frequency. The sub-area can thus "follow" a bright spot; it is described as consisting of about 8 lines of similar spacing to those of a normal whole-area scan (see Fig. 1), the usual line-blanking period being slightly extended to allow time for the sub-area scan. The line-blanking signals are used at G to gate the whole-area and sub-area video signals to a normal receiver/monitor and to X 0 , Y 0  respectively. Fig. 3 (not shown), illustrates the derivation of voltage signals representing the position of a luminance maximum by using local scanning timing signals and signals derived from the "topping-up" of a capacitor charged to a potential representing maximum luminance.

Filed: 1975-03-14
Abstract: 1500811 Removing H 2 S from gas mixtures EXXON RESEARCH & ENG CO 14 March 1975 [7 May 1974 24 Dec 1974] 10720/75 Heading C1A [Also in Division B1] Hydrogen sulphide and precursors thereof, e.g. carbonyl sulphide are removed from gaseous mixtures which are free of molecular oxygen by contacting the mixture with a sorbent comprising a rare earth metal oxide or compound which is decomposable to the oxide under the process conditions. The process is believed to proceed via the reversible formation of the metal sulphide or oxysulphide. The sorbent may be unsupported or supported, in the latter case preferably on a steamtreated inorganic support. The sorbent may also contain a compound of an alkali or alkaline earth metal, e.g. KOH. The preferred rare earth metals are lanthanum and didymium i.e. a cerium-free mixture of metals mainly comprising lanthanum, praseodymium and neodymium. The steam treatment of the support, e.g. alumina, silica &c., is effected at 700 to 1900 F. to decrease the surface area by about 20%. After impregnation with a water- or hydrocarbon-soluble compound of the rare earth metal, e.g. nitrate, acetate or carbonate, the support is dried, e.g. at 212-350 F., and then calcined at 900 F. and above. The gas absorption is generally carried out at 300 to 1000 F. Desorption is effected by contacting with steam followed by regeneration in an oxidizing atmosphere. The absorption-desorption may be carried out in parallel reactors.

Title: Process for manufacturing wood fibre panels
IPC: D21B1/12
Filed: 1952-04-30
Abstract: Wood fibre panels having a polished surface for direct use for building and decorative purposes are made as follows:- The wood, in fragmentary form, is boiled in water, then hot-treated with an aqueous sodium carbonate solution to neutralize the organic acids set free during boiling, and an aqueous sodium sulphite solution to eliminate part of the lignin contained in the wood.  The wood fragments are then disintegrated to form fibres, the fibres are brought into suspension in water, and the suspension is treated in a press with a filtering bottom to form moist panels, which are then hot-moulded in a multiple press to confer thereon a patterned glossy surface.  When the wood contains tannin the initial boiling in water is carried out to such an extent as to reduce the tannin content to not more than 1 per cent. based on the dry wood (large quantities of tannin form iron tannate which darkens the panels). Only 20 to 30 per cent. of the lignin may be eliminated by the sodium sulphite.  The proportion of salts used may be 7 per cent. of sodium sulphite and 0.7 per cent. of sodium carbonate (based on the dry wood).  The wood may be wood waste, e.g. that left by obtaining tannin from chestnut wood.
