Patent GB-1329009-A (GB)
Title: Inertia reel safety harness for use in vehicles
IPC: B60R22/405
Filed: 1970-09-28
Abstract: 1329009 Inertia reel G E W SVENSSON 28 Sept 1970 [1 Oct 1969] 46101/70 Heading A3V In an inertia reel device a ring 8 is displaced by sudden changes in the speed or direction of the vehicle and/or a high acceleration of the reel-out speed of the belt itself. The diameter of the ring 8 exceeds the diameter of a groove 7 in a reel head 3, in which the ring is accommodated so that in the neutral position the gap between the ring and the groove is at its widest vertically below the centre of the ring as in Fig. 3. On a sudden change in the speed or direction of the vehicle the ring acts as a pendulum, being displaced either forward as in Fig. 4 or sideways as in Fig. 2 (not shown) so that the gap at the bottom of the head 3 is narrowed. Narrowing of the gap causes displacement of operating means 9, which consists of a bent piece of wire, bringing a pawl 11, which is pivoted about 10, into engagement with one of the teeth of a ratchet wheel 4, thus locking the reel. If the reel is rotated by a sudden acceleration of the belt the inertia of the ring 8 causes it to lag behind the head 3, operating the locking mechanism in the same way. To increase the friction force between the groove and the ring a friction coating may be applied to the surface of the groove 7 or alternatively the ring may be provided with teeth to engage with corresponding teeth formed in the groove as in Fig. 5 (not shown).

The capacity to convey liquid by capillary action increases in the series batt 21, layer 22 and areas 23. The fibres are preferably kraft wood pulp or cotton and are less than “ inch in length, optionally blended with silk, wool nylon or cellulose acetate. Wood pulp fibres having a moisture content of 5 to 10% by weight are separated in grinder 27, airlaid onto belt 28 at 2 to 10oz/yd<SP>2</SP> and compressed by roll 29 to induce slight coherence by means of interfibre hydrogen bonding. The batt is sprayed with water whilst being transferred to belt 32 and then compacted by calender rolls 33, 34, at a pressure of 5 to 100 lbs/in<SP>2</SP> to form the denser surface layer 22. The web is then embossed by rolls 35, 36. Roll 35 may have annular ribs (38, Fig. 8, not shown) to produce recesses 24 running the length of the fabric, with areas 23, below recesses 24, of even higher density and water transporting capability than layer 22. The areas 23 penetrate into/batt 21 and strengthen it. In a second embodiment the embossing roll has two sets of ridges (67, Fig. 7, not shown) that cross at right-angles and impart a diamond pattern of recesses and associated higher density areas. In the embodiment of (Fig. 5, not shown) the denser layer and the array of still denser areas do not extend to the lateral edges of the rectangular sheet.

Abstract: 1,162,660. Aerials. HUGHES AIRCRAFT CO. 16 Oct., 1967 [31 Oct., 1966], No. 47045/67. Heading H4A. A radio wave reflector comprises two electrically conductive and flexible meshes or mesh portions which are preformed to define predetermined surfaces, means for supporting the meshes or mesh portions about their respective peripheries, and means for charging the meshes or mesh portions so that a preformed shape of at least one of them is maintained by the consequent electrostatic forces. As described, a reflector support structure comprising a tubular ring 30, Fig. 3, is attached to a spacecraft body 31 by means of three tubular arms 32, and a reflecting mesh 10 and a contouring grid 11 are attached at their peripheries to the said ring. The spacecraft body also carries a radio feed means 15 directed towards the reflecting mesh 10, and a conductive member 34 ending in a spherical member 33. The members comprising the mesh 10 may be quartz fibres coated with aluminium, and they are spaced apart by less than a wavelength at the highest frequency used. The members comprising the mesh 11 are spaced sufficiently apart to be substantially transparent to radio waves of the frequencies used. The ring 30 and the arms 32 are collapsible, and are extended when the spacecraft has been launched in orbit. The meshes 10, 11 are then electrified with the same polarity by means provided, charges of opposite sign being collected on the member 34. Electrostatic forces of repulsion cause the meshes 10, 11 to assume pre-formed shapes, that of the mesh 10 being such as to reflect waves from the feed means 15. Ion (or electron) expelling means may be provided instead of the members 33, 34 for removing the charges of opposite sign to those which maintain the shapes of the meshes.  In another embodiment (Fig. 4, not shown) the contouring grid and reflecting mesh are insulated from each other, and in use are charged with opposite polarities, and there is no unwanted charge for disposal. An embodiment is also described (Fig. 5, not shown) comprising a light weight reflecting mesh structure which is preformed into a closed cylinder. This may be deployed as a decoy or marker reflector in space. Other shaped closed meshes, such as spheres, are also suitable.

Abstract: 1,149,840. Photo-electric thickness measurement. INDUSTRIAL NUCLEONICS CORP. April 27, 1966 [April 27, 1965], No.48094/68. Divided out of 1,147, 946. Heading G1A. In producing a double sheet of plastics material by blowing a bubble of plastics material by means of an extruder having a circular die, rotating the extruder, die or bubble so that any variations in thickness due to imperfect extrusion are distributed around the bubble and then flattening the bubble to form the double sheet, the average thickness of the sheet is measured by either one photo-electric thickness gauge positioned in the centre of the sheet or several such gauges positioned across the sheet to equally divide the perimeter of the sheet. The output or outputs of the gauge or gauges are averaged for a period of time such that all the sheet material produced during one revolution of the extruder, die or bubble is inspected. The more gauges used, the shorter is this time, although the average thickness may be calculated over an integral multiple of this time. The gauge or gauges are maintained in position against changes in the width of the sheet. Infrared or ultraviolet radiation thickness gauges may be used. The speed of the take-up rollers of the sheet or the extrusion process is controlled according to the average thickness value.

Abstract: 1,167,391. Monitoring the degassing of molten steel. LECTROMELT CORP. 27 Oct., 1966 [18 Nov., 1965], No. 48194/65. Heading B1X. The rate of oxygen removal from vacuum degassing apparatus for treating molten steel, comprising a vacuum chamber connected to evacuating means, is determined by combining measurements of the proportion of at least one of the oxygen-containing gases in the discharge gases from the chamber, of the amount of molten metal treated therein, and of the rate of gas removal therefrom. As shown, molten steel 12 is drawn from a ladle 11 into a vacuum vessel 10 by the action of a steam ejector pumping system 25; the weight of the metal treated is determined by a strain gauge 66 attached to the ram 19 supporting the vessel 10, or by a measuring device 65 below the ladle 11, and this information is fed to a recorder 68 and to an analogue computer 30. The rate of gas removal is measured by determining the suction pressure of the pumping system 25 and converting it by means of an analogue function generator 70 into an electrical signal which is also fed to the analogue computer 30. A portion of the discharge gases is withdrawn through filters 44 and 51 and analysed for percentages of H 2 , CO, and CO 2  by a gas analyser 38, e.g. by a thermal conductivity cell for the H 2  and by infra-red cells for the CO and CO 2 . These percentages are recorded by recorders 58, 60, and that of the CO is transmitted also to the analogue computer 30. The original amount of oxygen present in the grade of steel being treated is determined empirically, and this information is also fed into the computer 30, enabling it to determine the amount of combined and free oxygen remaining in the melt.
