Title: Method of building a cantilever structure by succesive assembly of prefabricated elements
Inventor: MULLER JEAN
IPC: E01D21/10

Abstract: 1,210,680. Prestressed concrete bridges. ENTREPRISES CAMPENON BERNARD S.A. 14 Dec., 1967 [16 Dec., 1966], No. 56927/ 67. Heading E1G. In a method of building a prestressed concrete bridge wherein interlocking or other prefabricated elements V 1-5  and V<SP>1</SP> 1-5  are successively abutted and optionally adhered together to form cantilever arms extending from a support A, successive elements are temporarily secured by external prestressed rods or cables 11, Fig. 8, before being connected in opposed pairs by permanent internal prestressing wires 21. The rods 11 are stressed by removable jacks and are attached to one or more devices 4 removably keyed on the top of each element. The number of permanent prestressing anchorages 22 may thus be less than the number of elements. Adjacent elements may be prefabricated by casting against each other, and during assembly may be coated with polymerisable resin adhesive. Auxiliary tie rods 12, Fig. 4, may extend between internal anchorages 13 on adjacent elements. The devices 4 incorporate transverse handling pins (not shown). Meeting cantilever arms R 1 , F 2 , Fig. 8, are aligned in plan and elevation by screws or jocks 17 before being connected by a keying element V c .

Title: Apparatus for applying markings on roads and the like
Inventor: HARDING JOHN

Filed: 1966-12-28
Abstract: 1,211,690. Counting-apparatus. PRISMO UNIVERSAL Ltd. 28 Dec., 1967 [28 Dec., 1966], No. 57982/66. Heading G4D. [Also in Division E1]  In a vehicle for spraying continuous or intermittent road marking lines, a rear spray gun 25 powered by a compressor 15 sprays reflective material (e.g. ballotini) from a pressurized container 17 on to a strip of hot thermoplastic material deposited by a spray gun 24 from a heated storage unit 16, the guns 24, 25 being switched on and off by a solenoid-operated valve, Fig. 3 (not shown), controlled by an electronic cup-and-bucket counter, Fig. 5 operated by pulses from a reed switch 35 adjacent a ring of magnets 34 driven by a retractable road-engaging wheel 33. The vehicle includes a rear operator's control panel 18. The road surface ahead of the marking line may be sprayed with a wider strip of adhesive either by a gun 23 on the front of the vehicle or by an ancillary vehicle. For an intermittent line the counter automatically maintains a selected mark/space pattern irrespective of vehicle speed, the pattern being selected by ganged rotary switches 70 which determine both the number of pulses during which the guns 24, 25 are spraying and the number during which they are not spraying. A light 86 indicates when the guns are spraying. The accuracy of a selected mark/space ratio can be checked by observing this light while a manual switch 98 is repeatedly closed to apply pulses to the counter, switches 72, 83 being provided to disconnect the reed switch and spray guns. The counter circuit also includes a manual operating switch 84 and manual re-setting switches 91 93 for the beginning of a line or space. The spray guns 24, 25 (which may be duplicated for a wider mark) are mounted on a castorwheel carriage 26 carried by links 28 and a transverse slide 31. A laterally-adjustable adhesive spray gun 23 and a road-cleaning air jet 22 are mounted on a horizontally-pivoted guide arm 11. The jet 22 may be replaced by a rotary brush or sponge roller. The reflective ballotini are sprayed in excess to protect the hot thermoplastic from vehicle tyres. In order to allow for nearside, centre or offside road marking the vehicle cab 14 has dual controls and alternative operator seats are provided adjacent the control panel 18. Within the unit 16 thermoplastic, e.g. as in Specification 1,190,746, is melted by circulating oil at 400 F., the hot oil also circulating around the gun 24 and its feed pipe, and through jacketed storage vessels in the unit. In a modified vehicle, Figs. 6, 7 (not shown), the melter unit is replaced by heated storage vessels having stirring means for molten thermoplastic delivered by an ancillary vehicle.

Abstract: 1338597 Moulding microporous polyurethane articles BRITISH UNITED SHOE MACHINERY CO Ltd 10 Dec 1970 [12 Dec 1969] 58808/70 Heading B5A In a process for making microporous polyurethane articles, the polyurethane forming material includes, as an internal disperse phase, droplets of an organic liquid which is non- reactive with and non-solvent for the polyurethane forming material, and is present in an amount of 25-300% by weight of the polyurethane forming material; the reaction, to solidify the polyurethane forming material is carried out at a temperature below the boiling point of the organic liquid, so that the polyurethane product contains droplets of the organic liquid, which may be removed by evaporation or solvent extraction without expanding the polyurethane, to leave pores and discontinuities in the solid material. The examples relate to the production of shoe uppers by slush moulding (Figs. 1-3, not shown) or compression moulding techniques. Alternatively, the shoe upper may be formed by injection moulding using a split mould having a cavity of the desired shape and a mould core whose outer surface corresponds to the inner surface of the shoe upper to be formed (Figs. 4 and 5, not shown). In this latter case, fabric reinforcements or lining may be incorporated into the shoe upper, being supported on the core during the moulding process. The process may also be applied to the production of gloves. Specification 1,162,215 is referred to.

Title: Cryostatic Temperature Control System
IPC: F17C13/02
Filed: 1978-10-20
Abstract: A cryostatic temperature control system enables the cooling of an object to a selected temperature within a wide range, and maintaining that temperature, without excessive evaporation of liquefied gas coolant from the open cryostat. An inner, open container 4 contains a liquefied gas 8 and receives the object and is contained in an outer container 1 which contains liquefied gas 7 at a lower temperature than gas 8. A space 6 in double-walled inner container 4 contains a heat exchange medium 9 and the liquefied gas 7 cools the liquefied gas 8 to a desired temperature lower than its boiling point (thus minimising its evaporation). The amount of heat exchange medium within space 6 may be regulated and/or a heater may be provided in this space or at 14 to control the temperature. A stirrer 13 ensures uniform heat distribution. <IMAGE>
