Title: Improvements in ring balances having flexible pressure transmitting conduits
IPC: G01L7/24
Filed: 1952-02-11
Abstract: 703,131. Pressure gauges. LANDIS & GYR AKT.-GES. Feb. 11, 1952 [Feb. 27, 1951], No. 3591/52. Class 106 (2) A ring balance has flexible pressure transmitting conduits connected to the ring and arranged so that in the rest position of the ring they are unstressed, intersect the axis of rotation of the ring, and are straight where they extend through such point of intersection. The body 2 of a ring gauge is supported on a bracket 4 of a housing 1 by means of a knife-edge 3 and is divided at the top by a wall into two chambers to each of which is connected a piece of tubing 5, 6 whose free ends are bent forwardly and down so as to lie in a plane containing the axis of the ring. Two tubes 7, 8 are secured to the lower part of the housing 1 and are bent forwardly and up to lie in the said plane with their ends respectively in straight lines with the ends of the tubes 5, 6. The ends of the tubes 5, 7 and 6, 8 are joined by flexible tubes 9, 10 of rubber or other suitable flexible material which may be artificial. The tubes 9, 10 may be connected together by bands 11 of rubber or other material or they may be formed as a double tube 12 with dividing wall 13 preferably thinner than the outer walls. The plane in which the connecting points lie is shown as vertical but it may be inclined. A desirable condition of bending stressing of the conduits is obtained if they are arranged so that the distance from the axis of the ring to the points of connection to the tubes 5, 6 is made 2.85 times its distance from the fixed points of connection to the tubes 7, 8.

Title: Improvements in the manufacture of cast iron
IPC: C21C1/10
Filed: 1948-02-10
Abstract: A white cast iron, especially suitable for annealing, contains hypereutectic carbon in the form of nodular graphite and is produced by addition of cerium to a hypereutectic iron which on casting gives an iron containing not more than 0.02 per cent of sulphur and less than 0.5 per cent of phosphorus.  After the addition of cerium and immediately prior to casting, a graphitising inoculant such as ferro-silicon, calcium silicide or graphite may be added to the metal.  The quantity of cerium added may for example be up to 0.2 per cent.  The production of a cast iron of the following analysis is referred to: C 3.66 per cent, Si 2.96 per cent, Mn 0.60 per cent, S 0.017 per cent, P 0.044 per cent, Ce 0.051 per cent.
Patent GB-1380613-A (GB)
Title: Process and apparatus for producing nonwoven fabric and product produced thereby
IPC: D04H1/70
Filed: 1972-01-27
Abstract: 1380613 Non-woven fabric JOHNSON & JOHNSON 27 Jan 1972 [27 Jan 1971] 3867/72 Headings D1R and D2B A non-woven fabric having a uniform fibre density (number of fibres/unit volume) has areas of different opacity and fibre concentration (number of fibres/unit area). Areas 108 of low fibre concentration may be distributed irregularily but are preferably aligned in both the longitudinal and transverse directions of the fabric. Some or all of these areas may be perforations. The pattern is produced by supporting a fibrous web 31 upon an impermeable support roll 30 having for example a regular array of 100 round nubs (raised areas) per sq. in., 100 raised square areas per sq. in. or 25 round depressions per sq. in. and applying water or gas from jets 45 so as to move fibres from the areas of the nubs to adjacent areas. A random pattern is produced by means of a roll and having a polyurethane foam surface layer. The roll may be resilient or non resilient. Preferably web 31 is passed between roll 30 and a permeable woven nylon belt 32 tensioned by roll 38. The crossover points of the belt filaments protect the adjacent portions of the web from the displacing action of the fluid thereby adding a regular array of fibre clusters (102, Figs. 8, 9, not shown) to the pattern of less opaque areas. Water is removed by a suction box 47 situated outside the fibre displacing zone. The web may be an air-laid random web, an orientated carded web, wetlaid or a laminate. The “" to 2¢" length fibres may .be one or more of cotton, flax, glass, viscose rayon, cellulose acetate polyamide, polyester, acrylic or polyolefin. The web may be bonded after the fibre rearrangement by printing adhesive in an aqueous or non-aqueous medium by means of engraved roll 51, by impregnating or coating, or by incorporation of thermoplastic powder or fibres and heating to produce fusion. The fabric is dried by heated rolls 54.

Title: Method of obtaining a predetermined temperature of a metal foil arranged in a pyrolysis chamber by way of non-destructive measurement of temperature
IPC: G01N30/12
Filed: 1976-02-02
Abstract: This method, which is used especially for gas chromatography, produces a predetermined temperature in the central region of a metal foil (12) situated in a pyrolysis chamber (11) by nondestructive temperature measurement, the pyrolysis chamber being kept at a constant reference temperature. The foil is heated by passing constant-amplitude current pulses through it, and the pulse amplitudes can be set by resistors. The metal foil (12) is heated to a first chosen temperature, at least some of the radiation emitted by the metal foil as a result of heating being directed at a photodiode. The temperature of the foil is given by the diode output and the resistance of the foil is simultaneously determined at the first chosen temperature. A resistance/temperature value determined at a second chosen temperature is used together with the resistance/temperature value at the first chosen temperature to produce a graphical representation in the form of a straight line (Figure 3). This line is used to determine the resistance at the predetermined temperature (TD) to be produced and the resistors which alter the amplitude are set so that the pulses heat the foil to the resistance value (RD) obtained from the graphical representation, the resistance being monitored by an instrument. If this resistance value (RD) has been reached, the central region of the foil is at the predetermined temperature (TD) to be produced. <IMAGE>

Abstract: 1,095,661. Steering trailers; adjusting wheelbase. A. T. VAN HUET and W. HILDEBRANDT. Feb. 1, 1965 [Feb. 1, 1964], No. 4251/65. Headings B7D and B7H. The bogie frame 9 of a two axle trailer or semi-trailer is connected by a rotary bearing 6 to a trailer chassis 1 and by rotary bearings 16 and 20 to the first and second axles, the bearings being interconnected by means to simultaneously pivot the axles in opposite senses and to pivot the chassis relative to the bogie frame 9 when cornering, the means including at least one link 12 between the fixed part of the bearing 5 and the movable part of the bearing 16, whereby the axes of the wheels of trailer 26 and tractor radiate from a single point 31. Preferably two links 12, 13 are provided between the bearings 5 and 16 and two crossed links 12a, 13a between the bearings 16 and 20. One of each pair of links incorporates a resilient coupling 14 incorporating a rubber bush, a series of spring washers or a coil spring. Alternative or adjustable mountings 10 for the pivots 11 of the links 12, 13 may be provided for altering the angle between the links for use of the bogie with trailers of different lengths. In a development with three axles (Fig. 4) a two-axle bogie is connected by a rotary bearing 41 to a frame 44 which carries a third axle 45 and is connected by a rotary bearing 43 to the trailer chassis 1. A pair of parallel links 38 connect the chassis 1 to a plate 5b of the bearing 41 which is connected through transverse pivot 3 to a plate 5 on which are mounted the pivots 11 of the bogie links 12, 13. Thus as the chassis 1 is turned about the bearing 43 when cornering the mountings 10 of the link pivots 11 move in opposite directions relative to the bogie frame 9 thereby steering the front axle and, through links 12a, 13a, the second axle while the road reaction on the wheels of the last axle causes the frame 44 to rotate about the bearing 43. The transverse pins 3, 36 permit relative pitching of the axles and chassis. Rollers may be provided depending from the bogie frame to engage the tyres on tight curves and thus prevent the tyres from rubbing against each other. Adjusting wheelbase.-To adjust the position of the bogie the top member 2 of the transverse pivot is attached to the vehicle frame 1 by means of screws or other detachable fastenings.
