Title: Improvements in or relating to vehicle flashing-light installations
IPC: B60Q1/38
Filed: 1970-05-06
Abstract: 1,261,467. Lamp failure indicators. WESTFALISCHE METALL INDUSTRIE K.G. HUECK & CO. 6 May, 1970 [8 May, 1969], No. 21730/70. Heading G4N. In a system for reducing the intensity of a vehicle direction indicating lamp at night, a relay TN is activated when the headlights are switched on so that contacts tn1 and tn2 are opened. This brings resistors R1 and R2 in series with the tail lights BLh and so reduces the light intensity produced thereby. When current is flowing to the tail lamps relays E1 and E2 hold contacts e1 and e2 in the closed position so that if resistors R1 and R2 are in the circuit then parallel resistor R3 is in the circuit together with capacitor C3. This insures that the current drawn from flasher unit BG remains constant whether resistors R1 and R2 are in circuit or not. It should be noted that only one of the lamps BLh are inserted at any one time depending on the position of switch SR. If for any reason the lamp fails, relay e1 is open circuited so that the current drawn from the flashing unit BG drops to zero, no current being carried by the artificial load constituted by C3 and R3. Thus any lamp failure indicating device, whose operation depends on measuring the current drawn by the lamp is actuated, because the total current has dropped to zero. In a second embodiment the relays E1 and E2 are replaced by a single relay with a double coil and two loads of the type C3, R3.

Title: Improvements in screening
IPC: B07B1/28
Filed: 1936-08-07
Abstract: 479,466. Sifting-apparatus. STRAIN, G. H. Aug. 7, 1936, No. 21788. [Class 117] A method of screening consists in utilizing a screen to which a vibratory motion having a vertical component is imparted and which is suddenly stopped when its velocity is such that the material being screened is thrown clear of the surface, the screen being held stationary at the instant when the material again comes in contact with the surface whereupon it is moved downwardly with a velocity substantially the same as that of the materials. Preferably the screen has a simple harmonic motion in a straight line and is arrested at the point of maximum upward velocity, and the height to which the material is thrown is greater than half the diameter of the screen perforations. Apparatus for carrying the invention into effect is shown in the Figure. A screen 2 is supported by spring strips 3, and is driven by a crank 7 and connecting rod 8 passing freely through the screen frame and connected thereto through the medium of springs 9. Resilient buffers 10 on the screen frame engage fixed stops 11. Clamping and adjusting screws are provided for altering the position of the stops 11, and the position of the buffers 10 can be varied by adjusting the springs 9.

Abstract: 1341787 Semi-conductor material PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [27 Feb 1970] 22517/7I Heading C1A [Also in Division H1] Doped semi-conductor material from the vapour phase is deposited on a substrate arranged in a reaction vessel, by introducing reactive vapours including the constituents of the semi-conductor material into the vessel and directing the vapours towards the substrate in a stream of carrier gas, a liquid or solid source of doping impurity having negligible vapour pressure being situated in the reaction vessel upstream of the reactive vapour inlet and a flow of gas which does not react with the impurity source being also introduced into the reaction vessel upstream of the reactive vapour inlet and directed towards the substrate. The flow of non- reactive gas controls retrodiffusion of the reactive vapours to the impurity source (with which it reacts) and hence the amount of doping impurity conveyed in the stream to the substrate. In an embodiment, the apparatus comprises a reaction vessel 1 provided with a substrate supporting plate 5, a gas evacuation duct 17 and at the other end a tube 6, serving to feed gas for etching the substrate prior to deposition, a tube 8 for reactive vapour and carrier gas and a tube 12 for non-reactive gas. The least volatile material to be deposited is placed in 11 and doping impurity in 14. Deposits exemplified are III-V compounds, e.g. GaAs with dopants of Sn or Cr. The non-reactive gas may be hydrogen, the carrier gas may be nydrogen, and water vapour, halogen or a hydrogen halide may be employed in forming the reactive vapours.

Title: Improving textile fibres
IPC: D06P1/651
Filed: 1962-06-12
Abstract: The dichlorohydrin of ethylene glycol diglycidyl ether <FORM:0982953/C2/1> is made by heating to 90 DEG  C. under reflux a mixture of ethylene glycol, boron trifluoride in ethereal solution, and epichlorohydrin.  The dichlorohydrin <FORM:0982953/C2/2> is made by heating to 95-100 DEG  C. under reflux a mixture of monochloroglycerol, boron trifluoride in ethereal solution, and epichlorohydrin.ALSO:Fibres obtained by extrusion of mixes comprising essentially a crystalline olefin polymer and a polymeric basic nitrogen containing compound are subjected to the action of a dichlorohydrin and a strong alkali such that the corresponding diepoxide is formed in situ.  The dyeing properties of the fibres are thereby improved.  Dichlorohydrin treatment and alkali treatment may be effected simultaneously or in successive steps. Specified dichlorohydrins are ethyleneglycol diglycidyl ether dichlorohydrin and diglycidyl ether dichlorohydrin.  The alkali is preferably sodium hydroxide.  Treatment of the fibres may be continuous or discontinuous before and/or after stretching.  The dichlorohydrin may be used in aqueous or organic solvent solution or in the anhydrous state.  The amount of alkali added is preferably the stoichiometric amount necessary for the conversion of the dichlorohydrin to diepoxide.  In an example, a yarn obtained by melt spinning a mix of polypropylene and octadecylamine/epichlorohydrin/piperazine condensate is immersed in an aqueous solution of ethylene glycol diglycidyl ether dichlorohydrin containing caustic soda.  The yarn is then heated at 120 DEG C., for 20 minutes and dyed in baths containing 2.5% dye laced on fibre weight, with a fibre/bath ratio 1 : 40.  Dyeing with acid or metallized dyes is effected in presence of 3% ammonium acetate and 1% surfactant condensation product of ethylene oxide with an alkyl phenol.  Acetic acid is subsequently added to the bath.  Dyeing with plastosoluble dyes is carried out in presence of 2% surfactant.
