Abstract: 1333004 Moulding sliding clasp fasteners W URIG 24 Sept 1971 [31 Oct 1970] 44681/71 Heading B5A [Also in Division E2] In a method of producing stops for sliding clasp fasteners comprising woven tapes 2, 3 supporting toothed 4 of synthetic thermoplastic material, the interengaging filaments are melted at the positions of the stops and shaped to hollow formations by punches. The stop at one end of the fastener may comprise a single hollow stamping 6 and that at the other end two hollow stampings 7 which diverge and are shaped to allow a sliding clasp to move past them in a direction towards the stop 6 but which is retained by them when moved in the opposite direction. The stops 7 are reinforced by synthetic thermoplastic filaments 8. A gap 9 in the toothed filaments may be formed simultaneously with the formation of the stops, into which gap a clasp 10 is inserted so that as the fastener is conveyed through the apparatus the clasp is positioned between the two stops. The fastener tape is then cut at the gaps to produce individual fasteners.

Abstract: 1445023 Automatic control of evaporation WIEGAND KARLSRUHE GmbH 21 Oct 1974 45373/74 Headings G3N and G3R The output concentration and flow-rate of an evaporator are maintained constant by adjusting input flow, heat input to a heater, and heat supplied to a vaporizer, in dependence on varying concentration of the input supply. As shown, milk is supplied to a header tank 12 from where it is pumped 14 through a heater 16 and a series of vaporizers 18, 20, 22 to a discharge outlet 24. The supply concentration is measured by a sensor 26 providing a signal to an amplifier 30 which produces three output signals kl, k2, k3 for respective control circuits. In the first circuit, signal k 1 is combined with a nominal input flow signal b 1 and compared with an actual flow signal (z in a comparator E1 to produce a signal y1 which controls a flow regulator s1. The second control circuit receives the signal k2 and a temperature difference signal x2 and forms a control signal y2 which controls the supply of steam to the heater 16. The third circuit comprises a computing element R3 responsive to the signal k3 and a nominal evaporation ratio signal b3 to form a signal x3 which is compared with the input flow signal z and actual output flow signal a to produce a signal y3 which controls the flow-rate or pressure of steam supplied to the first vaporizer 18.

Abstract: 1408136 Burners; varying flame length BRITISH IRON & STEEL RESEARCH ASSOCIATION 29 Sept 1972 [1 Oct 1971] 45844/71 Heading F4T  A method of producing variable flame length from a stream of fuel and a stream of oxidant flowing into each other comprises, before the two streams contact each other, partly obstructing the stream of oxidant by a fluid obstacle to give said oxidant stream turbulence to promote intermixing of the two streams, the fluid obstacle being provided by discharging fluid with a component of movement in an upstream direction relative to the general direction of flow of the stream of oxidant and the length of flame produced by burning the resultant mixture being variable by varying the amount of obstruction provided by the fluid obstacle. A burner gun is located in a housing having an inlet for an oxidant and comprises concentric tubes 10, 11, 12, an oil inlet 21 through which oil is supplied to the centre of tube 12, an inlet 22 through which an atomizing fluid, e.g. steam or air, is supplied to annular space 16 and an inlet 23 through which the flame length control fluid, e.g. steam or air, is supplied to annular space 15. The control fluid issues from the gun through a ring of outlets 4 which are rearwardly directed so that turbulence is produced in a stream of oxidant flowing in the housing to meet the atomized fuel stream issuing from venturi 31 and nozzle 8. In a modification atomizing fluid is introduced into tube 52 and oil into annular space 54 between tubes 51, 52 and is atomized by the fluid discharging from tube 52. The control fluid issues from annular passage 53 through a rearwardly directed annular slot 63. Variation of flame length may be automatic, the distribution of heat provided by the flame being sensed to control adjustment of a valve in the control fluid supply so that the amount of obstruction provided by the fluid obstacle can be varied. One or more of the fuel, oxidant and fluid may be heated either by preheating or preheating the chamber in which the flame is to burn.
