Filed: 1920-04-21
Abstract: 142,120. Automobile Boat Manufacturing Co., (Assignees of Mazzei, W. C.). Feb. 28, 1914, [Convention date]. Boats adapted to run on land.-A motor vehicle or boat adapted to travel on land or water has a buoyant boatshaped body fitted with watertight doors and is propelled upon land and water from the same source of power, while the wheels have special watertight spring supports and are mounted in recesses in the hull so as to minimise resistance to travel through water. In the arrangement shown in Figs. 2 and 3, the drive from the engine. is transmitted through a friction clutch 37 and gear shaft 43 to either a shaft 44 or 45 connected by universal joints with shafts 40, 42 driving the propeller or rear wheels respectively. By the operation of a handle 50, the pinion 47 is moved into engagement with a pinion 43<c> to obtain a direct drive for the propeller the reverse drive being obtained by the engagement 'of a pinion 46 with an idler wheel 49 driven by the pinion 51. A three-speed gear for the rear wheels comprises pinions 52, 53, 54 slidable on the shaft 43 and adapted to gear with pinions 55, 56, 57 on the shaft 45, a reverse drive being obtained when the pinion 58 gears with the idler wheel 49. A lever 60 operates an emergency brake. The front wheels 4, Fig. 5, are mounted on stub axles, a short screwed stud 10 engaging a tubular member 11 which encloses a spring 13 and has a vertical sliding movement in a sleeve 14. The upper end of the spring rests against a shoulder of a spindle 15 which has an adjusting screw 19 at its upper end supporting the body part 1. The axle of the rear wheels, Fig. 7, extends through the hull or body of the vehicle. It is mounted in side cylindrical members 26 enclosed in members 24 which are adapted to slide in guides 20 and are attached to the under sides of springs 33. Bearing blocks 32 are arranged between the upper sides of these springs and cross pieces 22 of the members 20. Packing members prevent the access of water.

Title: Improvements in or relating to the manufacture of bituminous materials
IPC: C10C3/02
Filed: 1946-04-11
Abstract: A bituminous composition suitable for use as a binder for mineral aggregate, for jointing or caulking or for a protective coating or insulation is prepared by heating to about 360 DEG F., when frothing occurs, a fluxed mix of asphaltic bitumin with an unsaturated vegetable oil, in which mix sulphur, in quantity about half of the weight of the oil, has been incorporated, and then subjecting the frothy mass to a prolonged heat treatment at about 450 DEG F., the gases evolved being eradicated until a smooth homogeneous bubble-free mass is obtained.  Instead of asphaltic bitumin there may be employed a blend of asphaltic bitumin and refined Lake Asphalt in the ratio of about 6:1 by weight.  The vegetable oil is preferably linseed oil or may be rape oil or castor oil or a mixture of these oils, the proportion of oil to blend being preferably about 1 to 3 or 4. Fillers, particularly mineral fillers such as kaolin or china clay, may be incorporated before the final product has cooled and set.

Title: Immersion ultrasonic inspection system for the whole surface of flat bars
IPC: G01N29/22
Filed: 1973-03-08
Abstract: 1426954 Ultrasonic inspection devices; ultrasonic probes SUMITOMO METAL INDUSTRIES Ltd 8 March 1973 [9 March 1972] 11320/73 Headings H4D and H4J An ultrasonic inspection system includes an immersion tank through which flat bars to be inspected are transported by guide rollers, and first and second pluralities of probes arranged within the tank respectively above and below the path of the bars so as to project surface waves over the whole surface of a bar. In the embodiment shown, hot rolled bars 10 are conveyed two at a time through an immersion tank 41 by pinch rollers and guide rollers. Water jets from nozzles 45 cool the bars and pre-wet them to prevent the formation of air bubbles on them as they enter tank 41. A pulse-echo inspection of the bars with surface waves, to detect surface flaws, is made using probes 43 mounted on carriers 42. The probe positions, separations and inclinations are adjustable. Echo signals are indicated on a cathode-ray tube or a pen recorder. Compensation for attenuation of the ultrasonic signals with propagation distance is provided so that flaw size can be estimated quantitatively. The apparatus sensitivity is adjusted with the aid of reference specimens having artificial flaws. Air bubbles on the probes (and hence disturbing noises) are eliminated by directing water from an arcuate array of jets on to the probe faces (Figs. 4A to 4D, not shown).
Patent GB-926521-A (GB)
Title: Gas chromatography apparatus
IPC: G01N30/40
Filed: 1960-03-31
Abstract: A gas chromatography apparatus comprising a source of carrier gas, a sample injection device, a separating column and a measuring device connectable together in series, is characterized by the provision of a further device to enable the carrier gas source/column and column/detector connections to be interchanged to effect reversal of flow through the column.  The flow is intended to be reversed when the earlier components have left the column, in order to purge the column from residual components which emerge from that end of the column which they entered, as a single band which is measured by the detector.  As illustrated in Figs. 3, 4 and 10, the connections are made at an optically plane, polished face 24 of a block 14 containing passages therein which terminate at said face and lead to the various parts of the apparatus to be connected.  A polytetrafluorethylene ring 25 is in sliding contact with said face and co-operates gas-tightly therewith; it contains cut out portions 42, 43, 44 by means of which the ends of the passages in the block which lie at the corners of a regular hexagon, can be connected in pairs.  A disc 26 is keyed to supporting shaft 27 and ring 25 which is thus urged against the surface 24 by means of spring 28.  A lever 30 moves the ring into its alternative positions by rotation through 60 degrees. The carrier and sample gas enters the block through line 21 and connection 22 leading to channel 23 in the block which (in the position of ring 25 shown in Fig. 3) is connected by ring channel 42 to channel 31 in the block.  This leads to connection 15 to which the column is connected at one end and the other end of the column has a connection 16 to channel 32 in the block. This is connected in turn by ring channel 43 to further channels 34, 35, 33 in the block, the latter of <PICT:0926521/III/1> <PICT:0926521/III/2> <PICT:0926521/III/3> which is connected by ring channel 44 to channel 37 in the block which leads to a detector cell 38 formed in the block connected through channel 39 to outlet 40.  A similar comparison cell (not shown) is provided, and supplied by line 421.  A guard 46 is provided for the leads to the cells.  By rotating ring 25 through 60 degrees the connections of the column to line 21 and the detector cell are reversed.  If it is desired to use two columns in series, one end of one column being connected to the gas source and the other end of the other column being connected to the detector, a further pair of connections 17 and 18 are employed.  These are connected by channel 19 in the block and one column is placed between connections 15 and 18 and the other between connections 16 and 17.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 21, 1935.] [Class 38 (iv)] [See also Group XXXVII] Transformer arrangements.-A series booster transformer s1, s2, s3, has its primary p1, p2, p3, short circuited or connected across the supply in accordance with line voltage by the operation of a voltage responsive relay R the releasing voltage of which is made the same as the operating voltage by means, such as a resistance r inserted in series on operation of the relay, to reduce the voltage across the relay after it has operated. The relay is supplied through means such as a saturable choke 4 and resistance 6 or capacity which amplifies the voltage variations of the supply and means are also provided for retarding the reduction in voltage across the relay until after the relay has completed its operating movement. Such means may comprise a thermal switch 10, 11, Fig. 2, which is energized when an auxiliary contact a4 of the relay R closes and after a time delay inserts a resistance r in series with the relay winding. Alternatively the contact a4 may insert the resistance r and the relay arrangement is then connected across the :resistance 6 through a rectifier 7, and parallel condenser 8 and resistance 9, Fig. 3. The relay winding may replace the resistance 9 in which case the auxiliary contact of the relay short circuits part of the resistance 6 when the relay operates. The Specification as open to inspection under Sect. 91 disclosed arrangements in which the relay was supplied through a three-limbed transformer designed so that no secondary voltage was developed until a critical primary voltage was reached. Alternatively the relay was wholly or in part supplied through a discharge tube having a critical breakdown voltage. This subject-matter does not appear in the Specification as accepted.

Abstract: 648,829. Honeycomb or like paper &c. GRUNWALD, J. April 30, 1947, Nos. 11615 and 11616. Convention dates, May 3, 1943, and Nov. 1, 1943. [Class 96] [Also in Groups XIII, XVII and XXXII] A lattice-like structure which may be used for spring.systems, packing material, and sound and thermal insulation, consists of, e.g., paper, in which longitudinally extending rows of slits are made, the material then being deformed by moving material between adjacent rows of slits to form " carriers situated at one level integrally connected by rows of transverselyextending struts with carriers at another level, the carrier in at least one level being secured to another similar piece of material in the form of a cover or a plate. In one construction (Fig. 1) a sheet is slit as shown and parts or carriers 1, 5, 9 of the sheet are then held motionless while carriers 3, 7 are forced out of the plane of the drawing and towards the right thereof. The material between the slots is thereby caused to incline to the planes of the carriers and to twist, forming the oblique struts shown in Fig. 2. The struts can be made perpendicular to the plane of the carriers or to take up opposite inclination, as shown in Fig. 3, by altering the amount of lateral movement given to the carriers 3, 7. The cuts can all be given the same inclination in which the structure will during deformation, change in plan from a rectangular to a parallelogram shape; the cuts may also be arranged as shown in Fig. 6, or given the shape shown in Fig. 8, in which they have diagonally-opposite triangular lugs 17, which, to stiffen the structure, may be bent at right-angles to the strut. The finished structures may be arranged one on top of another and may be secured together either directly or by being each secured to a separating plate.
