Inventor: KIRKPATRICK MAURICE CASNER
IPC: E04D13/03
Filed: 1959-04-08
Abstract: 914,639. Skylights; glass substitutes; blinds. AMERICAN CYANAMID CO. April 8, 1959, No. 11872/59. Class 20 (3). A heat-reflective light-transmitting panel, e.g. for use as a domed skylight, Fig. 1, or as laths for a Venetian blind is composed of a sheet 1 of high light transmission plastic such as methyl methacrylate having embedded therein a sheet 12 of reflective, light-transmitting fabric comprising warp threads 14, Fig. 2, of non-metallic fibres such as rayon, cotton &c., and filler strands 15 of metallized plastic strips alternating with threads 16 of rayon or cotton which constitute spacers, the width of the strands 15 being such that the ratio of reflectivity to transmission is at least 1: 1, i.e. 50% of the direct rays falling on the panel is reflected back and 50% transmitted through the panel. Such a panel is made by laying a sheet of the fabric 12 on a polymerized sheet of methyl methacrylate and then applying liquid monomer so as to penetrate the sheet 12, after which a second sheet of methyl methacrylate is applied or formed in situ and heat and pressure applied to integrate the structure. Such a panel may be cut into slats for a Venetian blind. A domed skylight structure is made by two-thirds filling a shallow mould with partly polymerized but liquid methyl methacrylate, then laying the fabric 12 on the surface and cautiously immersing and then adding partly polymerized methyl methacrylate to fill the mould and completing polymerization and forming the panel to dome shape in a vacuum or pressure bag mould.

Title: Automatic knock-off devices for textile machinery
IPC: D01H13/18
Filed: 1960-04-05
Abstract: 954, 662. Stop motion. ALLGAUER MASCHINENBAU G.m.b.H. April 5,1960 [April 8, 1959; Dec. 16,1959], No.11935/60. Addition to 862,079. Heading D1D. The apparatus of the parent Specification is modified by the provision of means whereby the roller 1<SP>1</SP> is lifted off the roller 2<SP>1</SP> not only by the failure of the emergent thread 3<SP>1</SP> but also by the failure of one or more of the incoming yarns of which the thread 3<SP>1</SP> is composed. Each such yarn accordingly supports a pivoted weight e.g. 32d, which, if the yarn fails, tips to engage a bar 35. This rocks the slotted bar 11a to release the leverarm 10<SP>1</SP> and straighten the joint at 26<SP>1</SP> to cause lever 4<SP>1</SP> to lift off roller 1 and bring a tongue against the roller 2<SP>1</SP> to trap the thread and prevent it from lapping. As soon as the lever 101 pivots, a part 37 thereon engages the displaced weight to move it back in position. Means for braking the take-up spindle is also provided which is actuated on failure of an end; the brake is connected to one end of a pivoted lever 39 of which the other end is normally held depressed against the tension of a spring 40 by a roller on a short arm of a pivoted lever 42a of which the other arm extends as a handle outside the casing enclosing the parts. When the joint is straightened and lever 4-operative an extension of the part 37 engages the short arm of lever 42a and moves it over a dead-centre to lift the roller off the lever 39 so that the spring 40 rocks it and applies the brake, the external arm of lever 42a now becoming upright from which position it can be manually depressed to release the brake. The joint 26<SP>1</SP> can be reset by an external handle 47 which is integral with the extension of the part 37 which operates the lever 42a. The two levers 42a, 47 are so disposed that they can be operated together by one hand. The drop-pin 8<SP>1</SP> is now separately mounted on a pivot 36 and has an extension 8<SP>1</SP>a lying below the connection between the bar 35 and spindle 11a so that failure of the emergent end 3<SP>1</SP> also operates the lever 4<SP>1</SP>. An electromagnetically leaf-spring may be disposed beneath the drop wire 81 and an extension of the bar 35 to hold the parts in position when the apparatus is not in use e.g. during threading-up.

Abstract: 284,120. Blair, R. S. May 5, 1927. Internal fittings.- Apparatus for indicating the moisture of air, particularly applicable to a humidor receptacle, comprises a substance which changes its colour with changes of dampness and a coacting member provided with symbols which become visible bv colour contrast effect when the moisture content of the air is too great, or too little. The device is mounted in a frame 1 and comprises a strip 8 impregnated with cobalt chloride for example, which is blue when dry and becomes pink when wet. Adjacent the strip 8 is a. strip 2 divided into areas 3, 4 through which are respectively stencilled the signals " too wet " and " too dry," the part 3 being coloured blue and the part 4 pink so that when, for example, the strip 8 is blue the signal " too dry " becomes visible by colour contrast while the signal " too wet " is not seen. The device is seen through a window 6, the transparency of which is reduced by frosting or colouring so that the signals are only seen when there is a substantial colour contrast. Fig. 5 shows the device contained in the lower part of a glass humidor jar 12, the part 13, or the whole jar being coloured or frosted. The moisture indicating device extends wholly around the jar and the member 2 has a number of areas 17, 18. 19 alternately marked " too wet " and " too dry."

Title: Improvements relating to variable-speed gearing
IPC: F16H29/22
Filed: 1927-05-05
Abstract: 278,278. O'Sullivan, M. May 5, 1927. Variable-speed gearing comprises planet bevel gears b which are driven variably so as to roll round on a fixed crown wheel c and impart a variable speed to a. carrier p. The driving-element is a rotary involute cam a which causes the radial reciprocation of spring-returned nuts e relatively to helices d on the stems of the planets b. Each nut e has a ratchet connection with an arm f, Fig. 1, which slides in a slot in a pivoted guide h, the inclination of which depends on the angular position of a cam k. Each cam k is controlled through a rack l by a governor weight g carried by the driven element p. The weights g form collectively a governor which changes the speed automatically by changing the inclination of the guides h. When the speed is maximum, the governor brings in a positive solid-driving bolt (not shown). A sliding device y, Fig. 2, is for starting the drive. Means for reversing the drive comprises a toothed bevel train m, u, t.

Title: Improvements in or relating to submarine cable cutters
IPC: B63G7/04
Filed: 1954-04-26
Abstract: 750,964. Submarine mines destroying. OFFICINE MONCENISIO GIA ANONIMA BAUCHIERO. April 26, 1954 [April 28, 1953; Sept. 21, 1953], No. 12075/54. Classes- 9(2) and 92 A cable-cutting device comprises a cylin.- drical body 1 containing a hollow charge and closed at the forward end by a light. alloy cap 10, which prevents the entry of water into the conical charge liner 11. Therear end wall of the body 1 is fitted with a plug 13 housing a detonator 14 and a primer 16 protected by a copper cup 17. Attached to the rear of the body 1 is a casing containing the firing mechanism for detonating the primer 16 and comprising a pivoted lever 20 from which projects a striker 21, the lever 20 being urged forwardly by a spring 22 when released from a hooked lever 23. The lever 23 is connected by a rod 24 to levers 25, which are pivoted at the front of the body 1 on a support 7. A plate 28 carried by the rod 24 is connected by a shear wire 29 to a rib 3 on the body 1 and a safety-pin 19 extends through projections 18 adjacent the lever 23, which is immobilized before immersion by a hydrostatic safety device comprising a rod 30 extending from a piston 31 into a recess in the lever. A spring 34 holds the piston against a corrugated rubber diaphragm 33. The device is towed by a cable 8, which may carry several cutters. When the device is submerged to the required depth, the hydrostatic pressure forces the piston 31 rearwardly thus withdrawing the rod 30 to free the lever 23. A mooring cable encountered by the tow cable 8 is guided towards the levers 25 and on engagement with the levers the rod 24 is displaced rearwardly shearing the wire 29 and displacing the lever 23 to free the striker. The striker thereupon is urged by the spring 22 against the primer which fires the detonator 14 to explode the hollow charge, which cuts the cable. Extending downwardly from the support 7 is a vane 9 which acts as a stabilizer. The primer may be initiated electrically instead of mechanically. In a modification the body 1 is pivoted on the support, so that during operation it moves away from the support to prevent damage to the stabihzer. Control of the ignition mechanism is then dependent on movement of the device relative to the stabilizer when it contacts the cable.

Abstract: 336,934. Commercial Alcohol Co., Ltd., Arthur, J. S., and Gogarten, R. April 20, 1929. Drawings to Specification. Glucose &c.-Decomposition products such as polyoses and monoses are made from cellulose, cellulose-like substances, and cellulose-containing substances by hydrolysis with suitable acids. The starting material having naturally, or dried down to, a low moisture content such as 10 per cent or less, is treated with a mixture of steam and volatile acid gas such as hydrochloric or hydrofluoric acid gas in order primarily to distribute the water and acid uniformly throughout the material and is then decomposed with the same acid under such conditions of low temperature, e.g. -10 to -15‹ C., that no substantial formation of sugar takes place. The decomposed material is saccharified without removing the acid by a rapid hydrolysis between 50 and 100‹ C. by direct steam heat or indirect heating. The material is partly de-acidified and the sugars converted to monoses by treatment with steam under pressure, or by boiling with acidified water. An example is given of the treatment of dried sawdust.
