Abstract: 190,705. Bethune, G. de. Dec. 24, 1921, [Convention date]. Addition to 186,626. Tobacco pipes.-A device closely fitting in a chamber of a pipe and comprising coaxial tubes for lengthening the smoke passage has one of the tubes extended to the bowl, where it is perforated for the passage of the smoke, the edgesof the holes also serving to remove deposits from the bottom of the bowl when the device is withdrawn. As shown, the, extension 43 is formed on on outer tube 40 lining the chamber. This lining and the two coaxial tubes 7, 9 are coned to fit together at their ends nearest the bowl. Near the same end the intermediate tube 9 has perforations 10. The innermost tube 7 at its outer end is bent to form projections centring it in the tube 9 while allowing smoke to pass. A cap 34 closing the outer end of the intermediate tube 9 is made with a notched flange centring this tube within the chamber. The tubes are. held tightly together by the mouthpiece when this is forced on. According to the Specification as open to inspection under Sect. 91 (3) (a), the extension 43 and the lining 40 may be dispensed with. A further modification consists in fitting the inner tube; directly into a coned part'of the bore, while a reversely-coned part of the same tube receiver the end of the outer tube. In another form, coned ends of the two tubes and the lining fit together but are tapered in the reverse direction to that shown. The outer tube may be of elliptical cross-section. This subject-matter does not appear in the Specification as accepted.

Abstract: 758,260. Plugboards. PLESSEY CO., Ltd. Nov. 22, 1954 [Nov. 25, 1953], No. 32673/53. Class 38 (1). A terminal assembly is made up of a number of metal socket units 4 housed in metal casings 14 between partitions 2 of an insulating base 1, each unit providing three pairs of superposed sockets 10 with a slot 11 .separating the sockets of each pair. An apertured latch plate 18 extends through the slot 11, slots 15, 16 in the casing, and a slot 19 in a spring 17 which biases the latch plate so that apertures 20 are eccentrically disposed with respect to the sockets 10. When a ferrule 24 on a conductor is inserted into a socket 10, the pointed part'enters a hole 20 in the plate 18 and depresses it until the rim of the hole comes level with the groove 25 whereupon the latch plate springs up and locks the ferrule in place. Release of the ferrule is effected by depressing a knob 21. Spring clips 13 cover slots 12 in the sockets and contact the ferrules so as to improve the electrical connection.

Title: Manufacture of iron oxide colouring matters
IPC: C01G49/06
Filed: 1947-12-15
Abstract: Iron oxide pigments are made by treating with air an aqueous alkaline suspension of ferrous carbonate and a magnesium carbonate containing 0.1-7 parts magnesium per 100 parts iron, at a temperature not lower than 60 DEG  C., say up to 95 DEG  C.  There may also be present up to 10 parts zinc (as carbonate) and/or up to 4 parts aluminium (as hydroxide) per 100 parts of iron.  The suspension of ferrous and magnesium carbonates may be obtained by (i) adding an alkali metal carbonate solution to a mixed solution of a ferrous salt and magnesium salt, (ii) adding a precipitated magnesium carbonate to a ferrous salt solution and then adding alkali metal carbonate solution, or (iii) by mixing suspensions of the two carbonates.  The pigments may be struck on inert white bases; thus barium chloride solution may be added to the ferrous sulphate solution before precipitating the ferrous carbonate. Several examples are given.

Abstract: 1,179,770. Moulding skylight domes. H. H. ROBERTSON CO. 21 Feb., 1969, No. 33380/67. Heading B5A. [Also in Division El] A fibre-resin skylight dome, having an outer covering layer of an ultra-violet light weatherresistant material, such as polyvinylfluoride (PVF), is made by drawing a loosely clamped film of PVF into a vacuum mould, applying a layer of fibre-reinforced polyester resin to the film whilst retained by the mould, curing the fibre resin layer, and finally removing the composite article thus formed from the mould. The fibre is loosely clamped against a vacuum mould 13 by a frame 21 and, during the application of vacuum to draw the film into the mould, wrinkles or laps 26 which would normally appear are prevented by locally heating the appropriate regions of the sheet. The heat may be applied by a hot air blower 28 or a radiant heater 30. The heat causes the film to shrink in these regions thus taking up the wrinkles as they are formed.

Oct. 29, 1957, No. 33717/57. Classes 35 and 38 (4). A generator unit for supplying current of variable frequency to grinding spindle motors using four frequency ranges, comprises a variable-speed alternator A having two separate star-connected stator windings which may be connected in series or parallel, and a frequency doubling asynchronous generator C mounted on the same shaft, and arranged to be connected in circuit or not, at will. The generator is driven by a motor having stepless speed variation and its field winding 17 is constantly excited through resistor 21. Ganged switches a, b, c controlled by lever 46 serve to connect the generator output windings 1, 3, 5 and 2, 4, 6 in series or parallel to produce high or low voltage, and to connect the output directly, or through the frequency-doubler, to the output terminals 39, 40, 41. The frequency doubler, which is of the same pole-number as the alternator, is arranged not to alter the voltage. The four switch positions 1-4 of lever 46 correspond to connections to four separate grinder motors operating over successive speed ranges, speed control within each range being achieved by controlling the generator speed. For the lower part of the generator speed range its stator windings are connected in series, and for the upper part in parallel so that the voltages produced are similar. In addition, the frequency-doubler may be used or not, giving the four speed ranges. The machine may be two-phase.
