In a machine for handling wieners 14 an endless conveyer 13 the conveying run of which is horizontal in practice comprises a plurality of pockets 16 each holding one wiener 14 so that it lies transversely with respect to the conveyer 13 which has a downwardly extending discharge section at one end, Fig. 1 (not shown). A transfer belt 31 runs in the pockets 16, while they are traversing the conveying run but runs above the pockets 16 for most of their passage over the discharge section to lift the wieners 14 out of the pockets 16 and place them between and in contact with pairs of upper and lower endless belt conveyers 34, 36 and 43, 44 arranged on either side of the belt 31, Figs. 2 and 6 (not shown). The belts 34, 36 and 43, 44 run faster than the conveyer 13 and the belt 31 so that the wieners 14 are spaced out as indicated at 14a, 14b. An arm 50 counts the wieners 14 and controls mechanism (not detailed) for directing them into trays 51, 52.

Abstract: 1,054,102. Impregnating silicon carbide. KANTHAL A.B. June 11, 1963 [June 18, 1962], No. 23273/63. Heading C1A. [Also in Divisions C7 and H1] A resistance element consists of silicon carbide, the pores of which are filled (to less than 5% porosity) with SiC formed in situ, and additionally in the terminal parts with a metal silicide. It is manufactured by shaping, e.g. into rods, a mixture of carbon and SiC, with or without a carbonizable material; firing the terminal parts only whereby carbon is partially burnt off as CO; and impregnating the central part with Si, and the terminal parts with a metal silicide and Si (by surrounding the rod with tubes of the appropriate powdered material -extruded with a binder-and heating in a non-oxidizing atmosphere to melt the silicide). The carbon is burnt off by placing the ends of the rod in a furnace, or by protecting the central part with cooling coils, and firing, above 400‹ C. for amorphous carbon and at 1000‹ C. for graphite. SiC used may have particle size less than 43 Á, less than 10 Á, or graded up to a few mms.; carbon may be graphite, preferably colloidal, or amorphous carbon, e.g. carbon black; the carbonizable material may be a plastic, e.g. based on furan. MoSi 2 , TiSi 2  or other silicides of Ta, V, Nb, W, Cr, Ti, Zr and Hf may be used, with or without boron whereby SiB 4  or SiB 6  is formed. The product thus has a central part of SiC with up to 5% excess Si, and terminal parts of SiC with 25-60% silicide, the resistivities of these parts at 1500‹ C. being 200 and 15 ohms mm.<SP>2</SP>/m. resp. Excess Si may be carbonized by heating at 1800-2200‹ C. in CO.

Gas to be dried is drawn into dehumidifier 1 through hose 28 and inlets 15, 11 by fan 10, and then passes over desiccating core 8 before leaving through outlets 12, 18 and hose 29. Core 8 comprises a matrix of electrically conductive heating wire covered with a fire resistant insulating material, e.g. asbestos yarn, which is impregnated with a desiccant such as lithium chloride, silica gel, aluminium oxide or aluminium silicate. When the desiccant is exhausted, or after a predetermined time, inlet 15 and outlet 18 are closed by valves 17, 20 actuated by solenoid (27) (see Fig. 2, not shown). The same means opens inlet 16 and outlet 19 and also passes electric current through the wire of core 8, so that the effluent stream regenerates the exhausted desiccant. Thereafter, solenoid (27) is de-energised and the dehumidifier resumes its dehydrating function. The device is particularly suitable for drying the contents of closed containers connected thereto by hoses 28, 29.

Abstract: 1288843 Enzymes PFIZER CORP 15 April 1970 [12 July 1969] 18070/70 Heading C3H [Also in Divisions C2 and C6] The isolation yield of fermentation product, such as antibiotic or penicillin acylase, from a fermentation broth is increased by introducing protease, cellulase or lysozyme and, optionally, a chelating agent e.g. ethylenediamine tetraacetic acid or tris(hydroxy-ethyl) amino-methane, into the broth before isolating the product. The following enzymes are mentioned: proteases including bromelain, chymotrypsin, ficin, papain, pepsin and trypsin; cellulases; and various lysozymes. The enzyme and chelating agent should each be added in concentrations of at least 10 p.p.m. According to one of the examples, lysozyme is added at a level of 100 p.p.m. to a whole culture fermentation broth of Proteus rettgeri ATCC 9918. Quantitative penicillin acylase present is determined by the addition of benzylpenicillin which is hydrolysed to 6-amino penicillanic acid. The broth is filtered, adjusted to pH 2À5-3À0 with dilute hydrochloric acid and extracted with methyl isobutyl ketone to remove unconverted benzylpenicillin. The pH of the aqueous 6 - aminopenicillanic acid - containing phase is raised to pH 7À5 and phenylacetyl chloride is added. After 50 minutes at room temperature with continuous agitation, the pH is adjusted to 6À5 and the broth is bioassayed for benzylpenicillin. Significantly higher levels of penicillin acylase were obtained with the lysozyme treated broth.

Abstract: 1310024 Drawing board stands ADMEL INTERNATIONAL Ltd 6 Aug 1971 [11 May 1970] 22674/70 Heading A4H  . A drawing board stand includes a main frame 1, a sub-frame 3 pivoted to the main frame about a horizontal axis 35, a drawing board 5 supported on the sub-frame for sliding movement normal to axis 35, spring means 67 providing a counterbalance force to counter-balance the weight of the board during sliding, a first linkage connecting the spring means 67 to the board 5 so that, for any given inclination of the sub-frame 3, the counterbalance force is substantially constant, biasing means 13 to counter-balance pivotal movement of the sub-frame, and a second linkage to alter said counter-balance force dependent upon the inclination of the sub-frame. The first linkage includes bracket 41 pivoted on the sub-frame.3 at 43, a lever arm 45 rigid with brackets 41, a suspension arm 47 pivoted to arm 45 at 49 and to board 5 :at 51, a rail 53 secured to brackets 41, a roller pivot 57 arranged to roll up and down rail 53, and a link 61, 63 carrying roller pivot 57 and mounting the coil springs 67. When the 'board 5 is slid up and down, arrow X, parts 45, 41, 53, pivot about 43, link 63 moves parallel to its axis thereby extending and retracting the springs 67. When the sub-frame 3 is pivoted about 35, the roller pivot 57 rolls on rail 53 between a first maximum moment position spaced from pivot 43, when the sub-frame 3 is vertical, and a second zero moment position in which pivot 57 coincides with pivot 43, when the sub-frame is horizontal. Since this moment due to springs 67 about pivot 43 is changed, the counterbalance force will be altered, and change in this moment upon pivoting of the sub-frame is caused by said second linkage which includes a link 71 pivoted to link 61 at 73 and to a rocker arm 75 at 77, which arm 75 is pivoted at 79 to the sub-frame 3, and a turnbuckle 89 connected by respective, universal joints 85, 87 and 91 to the arm 75 and to the main frame 1. When the board is in an overhang position, e.g. it is in its fully down position, i.e., to the right in Fig.1, the weight of the board 5 tends to pivot the sub-frame 3 anti-clockwise, Fig.1, about axis 35, This tendency is counteracted by a feedback force in link 71 which acts through arm 75 and turn-buckle 89 and tends to couple the sub-frame 3 in the opposite sense. The board can be locked at the desired inclination and height. The biasing means 13 is connected by two wires 9, 15 to a crank arm 7 so that the coil spring 13 is extended or retracted a distance twice that moved by arm 7. An alternative biasing means may comprise a coil spring 111 connected by a wire 101 to the main frame 1 at 103 and through a tension adjuster 113 by a wire 101a to the main frame at 103a or 91, the wires 101, 101a passing over pulleys 105 on the sub-frame 3.

In Fig. 4 the gas extraction system includes vertical access trunks 14 extending upwardly from longitudinal cargo oil ducts 10 to main deck 16 where they terminate in covered coamings 17. Ducts 10 and trunks 14 are preferably adjacent longitudinal bulkheads 15 and have smooth internal surfaces. Control valves 18, Fig. 7, are fitted in the ducts associated with the cargo tanks and are provided with hoods 19 to direct the gas into the valve at 20.
