Abstract: 1,259,646. Method and apparatus for manufacturing blasting caps. NITRO NOBEL A.B. 21 Feb., 1969 [21 Feb., 1968], No. 9401/69. Heading F3A. A method of manufacturing electric blasting caps of the kind in which a sleeve enclosing an explosive charge is crimped around a deformable plug carrying a pair of conductors which are connected to a filament embedded in a priming composition, comprises a step of passing a measuring electric current through the filament and conductors before the crimping operation to obtain a measurement of the resistance, and preventing operation of the crimping tool if the measured resistance lies outside an acceptable range. If the blasting cap is of the delay type the current is passed for a time corresponding to the delay period before the crimping tool is activated or rendered inoperative. Audible or visual signals indicate whether the resistance is too high. During the crimping operation the measuring current is continued and changes in resistance are indicated by visual or audible signals. The current for measuring resistance is one-tenth the minimum required to cause detonation. An apparatus for use in the method is also claimed.

The articles or materials may be formed by calendering, injection moulding or blow moulding. Examples disclose moulding compositions comprising polyethylene, ethylenepropylene rubber (viscosity improver) and filler, or polyvinyl chloride, dibutyl phthalate, zinc stearate, styrene-butadiene rubber and resin (viscosity improvers) and filler. The filler may be by-product gypsum from the phosphoric acid (phosphate) industry, gypsum burnt within an electric furnace and thereafter pulverized, gypsum treated for 60 minutes with 60% H 2 SO 4  at 100‹ C. and thereafter air-dried, bleached gypsum, anhydrous gypsum, or the calcium sulphate obtained by pulverizing the product produced by causing the hemi-hydrate to absorb water.

Abstract: 1,266,056. Pressure casting machines. BUHLER A.G. GEB. 6 June, 1969 [12 June, 1968], No. 28858/69. Heading B3F. [Also in Division G3] In a hot chamber pressure casting machine having a movable die 4 and a stationary die 2, the metallic injection nozzle 25 which conducts molten metal from a gooseneck 24 to the mould cavity 5 is heated by passing an electric current through it. Current flows from a transformer 41 via line 54, connector 32, pump 12, nozzle 25, stationary die 2 and connector 33 and returns via line 51. The temperature of the nozzle 25 is measured by a thermoelement 66 which is connected to a potentiometer 76, an amplifier 63 and a temperature indicating device 67. A reference voltage corresponding to the operating temperature of the nozzle 25 is fed to the amplifier 63 by a tap 75 of the potentiometer 76 ; of the voltage generated by the thermoelement 66 exceeds the reference voltage, the amplifier 63 deprives the solenoid 55 of current and the switch 49 opens to shut off the current to the transformer 41 and thus to the nozzle 25. When the temperature of the nozzle 25 falls below a certain value, the switch 49 is closed and current again flows through the nozzle. The crosssection of the nozzle may vary over its length so as to give rise to zones having different temperatures.

Abstract: 1297936 Magnetic structures EMI Ltd 16 Feb 1970 [22 Feb 1969] 9647/69 Heading H1H [Also in Division C7] A magnetic recording medium comprises a substrate coated with a layer consisting substantially only of a mixture of cobalt and chromium, the chromium being distributed throughout the thickness of the layer such that the per cent wt. of chromium is 1-20%. The structure is made by depositing the metals on to the substrate at a temperature not substantially exceeding 100 C. The recording medium may be a polyester film bearing a layer of cobalt-chromium (0À1-1 Á thick; 3-10% Cr) evaporated on to the film. The concentration of chromium in the layer may be higher, e.g. 20%, adjacent the substrate than adjacent the layer surface, e.g. 4%. In one embodiment, an aluminium drum 2 wrapped in polyester film strip 1 is rotated by motor 7 in evacuated chamber 8 over crucible 10 heated by radio frequency source 12. A chromium-cobalt ingot in the crucible is evaporated at 1600-1800 C. to deposit the metals on the film. The initial part of the layer is richer in the more volatile chromium. Alternatively, a wire or wires may be fed to an evaporator or the layer may be formed by sputtering. Instead of winding the substrate on a drum, it can be wound on spools for passage back and forth across an evaporating source or sources. The metals can be impinged on the substrate at a particular angle of incidence by performing the deposition in a directional magnetic field. The products have improved hysteresis loop squareness, coercivities of 300-500 Oe and Br 6000-8000 lines/cm.<SP>2</SP>

Thus, a threadline travelling between delivery, and collection means e.g. a suction gun, and previously passed through a traveller ring, is engaged, using the tool shown in Fig. 1, in a guide slot 4. The flattened and dished end 3 is inserted under the end of a traveller on the ring, a trigger 6 is pulled to cause a spring-loaded sleeve 5 to cover the slot 4 and permit the threadline to slide along member 1, over the end 3 into the traveller, whereupon the tool is withdrawn. A thread in the form of a staple fibre strand may be reinforced by falsetwisting (e.g. imparted by a suction gun) to enable such threading operation with the tool of Fig. 4, a guide rod 14, which in one position engages and restrains the threadline, is pivoted by pull on a trigger 15 into a position whereat the restraint is removed. Fig. 5 shows a tool comprising a guide slot 24 for engaging and restraining the threadline which is blown therefrom by compressed air supplied through a tube 26 when a valve 27 is momentarily opened.

A piston 26 is movable in a tube 16 surrounding a headlamp glass 18, against the action of a spring 28, by liquid supplied via one-way valve 46 in an inlet pipe 42, to rotate wiper arms 10, 12, 14 of which the arm 10 is connected by a link 38 to the piston 26. When the piston head 32 passes an outlet pipe 48 liquid is discharged through the latter onto the glass 18. Alternatively the outlet pipe 48 is replaced by a pipe 58, Fig. 2 (not shown), through which liquid is discharged when a second piston 54 is moved after the piston 26 has completed its movement. In two further embodiments, Figs.4 and 5 (not shown), one or two wiper blade(s) is or are attached, for movement linearly over a rectangular lamp glass, to two pistons located in the limits of a U-shaped tube. A further embodiment, Fig.6, (not shown), is a modification of that illustrated  in Fig.1, in which liquid is fed into an expandable tube (107) to drive the piston. When the tube is fully expanded a ball valve is actuated to release its contents through a spraying nozzle onto the lamp glass.
