Title: Means for applying pitching motion to marine craft
IPC: B63B35/10
Filed: 1954-03-23
Abstract: 750,855. Ice-breakers; augmenting pitching. WAAS, H. March 23, 1954, No. 8429/54. Class 113. [Also in Group XV] In a marine craft, e.g. an ice-breaker, means are provided for imparting a pitching movement to the craft which is approximately in resonance with the natural pitching period of the craft. The means for augmenting the pitching motion may comprise the transference of liquid between tanks forward and aft, or by periodic changing of the contents of a tank forward or in the stern. In the embodiment of Fig. 3 said means comprises weights 2 fixed to a shaft 1 rotated by a belt 6 attached to a gear mechanism 4 driven by a motor 3, the weights being of the same size, at the same radius from the shaft 1, and displaced one from the other by 180 degrees. By using one weight only, or weights of a different size and/or at different radii, the craft will perform a pitching, rolling, and yawing movement.

Title: Colorimetric test for serum enzymes
IPC: C12Q1/32
Filed: 1960-03-10
Abstract: A composition for detecting a diphosphopyridine nucleotide-linked enzyme comprises (a) a substrate for said enzyme, (b) diphosphopyridine nucleotide, (c) diaphorase and (d) a colour indicator having an oxidation-reduction potential above that of the diphosphopyridine nucleotide-reduced diphosphopyridine nucleotide system which is not subject to autoxidation, said composition being buffered to pH 5-9 nda the amount of diaphorase being sufficient to oxidize reduced diphosphopyridine nucleotide. In the specified compositions, the colour indicator is 2:6-dichlorindophenol and in addition to the above-mentioned components, albumin is added to stabilize the system; the buffer is a potassium phosphate or tris-hydroxymethylamine phosphate buffer.  Dibromoindophenol and other substituted indophenols may also be employed as indicators. For detecting the following dehydrogenases: lactic, glutamic, malic, glyceraldehyde phosphate, and alpha-glycerophosphate dehydrogenase, the following substrates respectively were employed: a salt of lactic acid, a salt of glutamic acid, a salt of malic acid, a salt of arsenic acid and 3-phosphoglyceraldehyde, and a salt of alpha-glycerophosphate in phosphoric acid.  The ingredients may be used to impregnate a bibulous material such as a filter paper, paper strip, or a cellulose tablet, to which a drop of the liquid to be tested is applied, or may be used in the form of a solution. Specification 893,300 is referred to.

Filed: 1926-03-30
Abstract: 273,784. Wright, G., and Penney & Porter (Engineers), Ltd. March 30, 1926. Variable-speed ratchet gearing.-In an acetylene generator, calcium carbide is fed from a hopper to a rotatable horizontal or slightly inclined conveyer cylinder T rotated by a variable-speed ratchet gear in which a ratchet-wheel V is driven by a ratchet carried by a lever L which at its upper end is fitted with a pin M engaging a slide link S. The lower end of this is connected by an eccentric rod to an eccentric on the shaft D, the upper end being similarly connected to a strap on the shaft itself, so that this end receives no reciprocating motion. The throw of the ratchet is varied by varying the position of the link S by means of a chain or cable C which may be connected to the gas holder or to a pressure gauge, or may be varied by hand.

Classes 142(i) and 142(ii) A fabric is cut while on the loom by a knife that is guided between the warp threads by a device woven into the fabric and which causes the knife to move laterally to follow any deviation of the warp threads from their normal path. A knife 31, mounted to slide on a shaft 35, is guided by a slotted guide 28 which is woven into the fabric and secured by a cord 27 to a stationary part of the loom. The cord 27 passes through one of the healds and is shed with the warps. The cord may be made of nylon. Binding or selvedge forming warp threads 21, 22 and 23, 24 may be provided on one or both sides of the knife. These threads are twisted by twisting discs 19, 20.

Heading B8T. A container 1, with a rolled upper edge 2, is closed by a dished lid 5 having an annular groove 6 containing a packing member 7 which fits over the edge 2. The groove is of substantially semi-circular cross-section, and the packing member is of part-circular cross-section. The skirt 10 of the lid terminates in a beaded edge 11 which engages beneath a shoulder 15 of the container. The edge 11 of the lid is reduced in diameter and thus attached to the container by a bell-shaped tool 13 which is forced downwardly and co-operates with a piston 12 bearing on the top of the lid. In other embodiments, the edge 11 of the lid engages beneath the edge 2 of the container, or mutual grooves 50 may be formed in the container and lid, Fig. 11, by rollers, not shown, spaced around the circumference. In Fig. 3 the edge of the container is rolled outwardly, and a tool for radially compressing the head of the closure includes a number of circumferentially and closely spaced levers 19, each pivoted about a shaft 20; their lower ends are pivoted inwardly when their upper ends 19<SP>1</SP> are engaged by a piston 22. Instead of the piston 22, a bellshaped plunger 25 may urge the lower ends of the levers inwards. In Fig. 7 the beaded edge of the closure is compressed on to the container by an annular spring 30 which surrounds the container and closure, and which is compressed by a jaw tool 31, 32. The spring may be subdivided at 37 and have tangential lugs 33 for closing purposes. Alternatively, the closure bead is compressed by rollers 38, Fig. 8, driven about pins 39 by toothed wheels 45, and interengaged by teeth 44.

Abstract: In a process for the regeneration of adsorptively active g -aluminium oxide having 1 to 10% by weight of organic substance (e.g. mineral oil) attached to its surfaces, the aluminium oxide falls from a hopper 1 through a hot regenerating zone in a column 4 in which the attached substances are burnt off by air oxygen supplied through a nozzle 8, the length of the zone and the duration of combustion being so short (e.g. 1 to 2 <PICT:0881485/III/1> metres and less than 2 seconds respectively) that the heat of combustion passes to the ambient gas phase and the aluminium oxide is not heated above the temperature at which it becomes adsorptively inactive a -aluminium oxide.  The zone is heated by electric elements 9, but the current supply is reduced or switched off after some time as sufficient heat is provided by combustion of the organic substance, the column 4 being surrounded by insulation 12.  The air or oxygen may be pre-heated by passing it through a pipe 10 and over heaters 9.  Gases pass off through a vent 6 and regenerated aluminium oxide is discharged by an outlet 7.

The surface of elongated metal stock such as wire, rod or tube, is cleaned by a rotating plasma arc. The stock is guided by conductive rollers 12, 14, 16 and pulled by a winding drum 18 through a first electrode 20 and two opposed electrodes 40, 42. Electrode 20 has a water coolant chamber 22, an arc-striking power supply 30 and an arc-sustaining power supply 32; both are applied to the stock through rollers 14 and may be of alternating or direct current. An electromagnet 26 fed by supply 28 produces an axial field which concentrates the arc in the small electrode bore 24A and effects rotation of the arc. Air is induced through the small aperture 24A and exhausted through large bore 24C. Electrodes 40, 42 are fed by arc-striking sources 48, 52 and sustaining sources 50, 54. An electromagnet 56 concentrates and rotates the arc and air is drawn from the outside of the electrodes and exhausted into the space between them. Instead of air, argon, helium, nitrogen or hydrogen may be used. Other materials may be fed into the arc for deposition on the stock. The process may also serve for heat treating the stock.
