Title: Improvements in or relating to magnetically operated electrical switching devices having conducting-liquid contacts
Inventor: NICHOLLS HEDLEY JOHN
IPC: H01H53/08
Filed: 1955-08-24
Abstract: 798,191. Converting. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 21, 1956 [Aug. 24, 1955], No. 24336/55. Class 38 (2). [Also in Group XXXVII] A switching device comprises a tube T joined at its ends to form a closed loop and entirely filled with an endless chain of two or more liquid sections which are alternately conducting and non-conducting. As shown in Fig. 2 there is a single conducting section D1, e.g. of mercury, to which a magnetic material may be added, and the remainder of the tube is filled with a non- conducting section. Pairs of contacts 1a, 1b, 2a, 2b, &c., are spaced along the tube length and at each contact pair a magnetic field is produced (by means not shown) in a direction at rightangles to the tube length and the current path between a contact pair, so that a force is exerted upon the section D1 each time it bridges a pair of contacts and the liquid chain circulates round the tube. The device may be used to produce pulses sequentially in a number of lines connected to the respective contact pairs, but as shown it is used as a converter, the D.C. source B being connected to the centre tap of the transformer primary and the outer ends of the primary being respectively connected to alternate ones 1a, 3a, &c. of the contact pairs whereby the load L1 is energized with A.C. To increase the frequency of the output without increasing the speed of liquid circulation a number of sections D1 are used (Fig. 3, not shown). In another arrangement (Fig. 4, not shown) in which two separate A.C. outputs are derived from a single D.C. input there are eight equally-spaced contact pairs and four conducting sections D 1 so spaced that at least one contact pair is always bridged whereby the arrangement is self-starting. The A.C. output may be re-converted to D.C. (Fig. 5, not shown) by centre-tapping the transformer secondary and connecting the secondary to further contact pairs on the tube in a manner similar to the primary, there being at least two sections D1, the arrangement being such that when one section D1 is bridging one " primary " contact pair, the other section D1 is bridging one " secondary " contact pair. Alternatively, two tubes may be provided operating in synchronism, one tube having the " primary " contacts and the other the " secondary " contacts.

Title: Distribution of filter tips
IPC: A24C5/47
Filed: 1963-06-20
Abstract: 1,024,281. Cigarette-making machines. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. June 20, 1963 [June 23, 1962], No. 24499/63. Heading A2C. Six-fold filter lengths are fed from a hopper 1 to a supply drum 2 and are placed in every third groove of a distributing cylinder 4. The periphery of the drum 4 is divided into two sections 4a, equal to a third of the width of the periphery, and 4b equal to two-thirds of the width of the periphery. A cutting knife 14 operates between the two sections. The drum 4 is driven by a sprocket 5 and an endless link chain 6, each link being of a length equivalent to the distance between successive grooves. The links are provided with successive abutments 8, 10 and 12, the abutments 8 and 10 being of such a length that a sixfold filter fits exactly a groove in the drum 4, and the abutment 12 being of a shorter length such that a double length filter is not engaged by the knife 14. The number of links of the chain is such that on successive revolutions of the drum each groove co-acts with abutment 8, 10 and 12 in succession. In operation, the six-fold filter is blown against an abutment 8 and severed into a two-fold filter and a fourfold filter by the knife 14 on the first revolution of the drum. The two-fold filter is taken off by a drum 15. The groove containing the four-fold filter comes adjacent an abutment 10 on the next revolution of the drum. The four-fold filter is then blown against the abutment 10 and is cut into two two-fold filters one of which is taken by the drum 15. The remaining twofold filter is blown against an abutment 12 with which its groove has come into cooperation during the next revolution of the drum, is unaffected by the knife 14 and is in turn taken by the drum 15. If eight-fold filters are to be cut, they are fed to every fourth groove of the drum 4 which is divided into two parts in the ratio 1:3, and the chain 6 is provided with a sequence of three longer and one shorter abutments. In a further embodiment, the multiple length filters may be fed to a further drum before being passed to the drum 4. The knife 14 co-operates with both drums and an initial two-fold filter length is cut on the further drum on which it remains. The remaining multiple length filter is passed to the drum 4, cut into two-fold lengths by the knife 14 and passed back to the further drum (Figs. 5 and 6, not shown).

Abstract: 1,152,777. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 7 May, 1968 [26 May, 1967], No. 24507/67. Heading G6C. The sheath 1 of a fuel element has a localized thickening of its wall to form an external elongate protuberance 2 aligned with the longitudinal axis of the sheath, one end surface 4 of the protuberance having a shallow inclination to the longitudinal axis to form a streamline contour for coolant flow and a blind bore 5 extending parallel with the longitudinal axis from the opposite end surface 7 for housing a thermocouple hot junction 6. The coolant flow is in the direction of the arrow F. Squaresection projections 8 extend peripherally about the sheath 1 and over the protuberance 2 to provide a heat transfer roughening. Behind the protuberance 2 the projections 8 form thin fins 9 which are slotted to retain a thermocouple conductor 10. The protuberance 2 causes little disturbance to the coolant flow and the heat transfer pattern so that the temperature indicated by the thermocouple is substantially that of the unthickened part of the sheath.

Abstract: 723,836. Piston packing. THOMPSON PRODUCTS, Inc. Oct. 1, 1952, No. 24573/52. Class 122 (1). [Also in Group XXII] A resilient piston-ring 10 comprises two rings of segments 15, 16 joined by webs 17, and struts 18 displaced radially-outward from the axially-extending portions 17b of the webs, each strut having an end-portion 18a integral with the centre portion of a segment and a free end 18c spanning the space between opposite adjacent segments and engaging the end portions of these segments. The ring, which is made from a strip of spring metal (see Group XXII) before the metal is hardened and tempered, is compressed in an oil groove 27 of the piston 28 so that when allowed to expand it will press against the cylinder 29 to remove oil and discharge it through drain holes 31 in the piston. The thickness of the metal tapers towards the scraping edges 22, 23 of the segments which are separated by gaps 25 of substantially constant width. It is stated that the flexibility of the ring will enable it to conform to the shape of the cylinder even when the cylinder has worn out of correct shape. In a modification, Fig. 12, the struts 48 extend between the segments 45, 46 without first intersecting the plane of the webs 47 joining the segments.

Title: Improvements relating to the production of nickel carbonyl
IPC: C01G53/02
Filed: 1936-09-09
Abstract: A material suitable for the preparation of nickel carbonyl by direct treatment with carbon monoxide under pressure is obtained by reducing a sintered nickel matte by heating it with a solid or liquid carbonaceous material.  Suitable carbonaceous materials are coal, coke or anthracite, preferably in the form of dust, or a heavy oil. "Second bottoms" from the Orford "tops and bottoms" process may be passed through a sintering machine, the sulphides being converted into oxides with the evolution of sufficient heat to cause sintering. The sintered matte, preferably in coarse granular form may be mixed with granular or finely divided solid carbonaceous material, 30 per cent by weight of the matte preferably being used, and the mixture being heated in a rotary kiln to temperatures of 750-1000 DEG  C., say 900 DEG  C. The sintered and reduced matte, if desired after a magnetic separation from excess carbonaceous material, may be treated with carbon monoxide under pressures of 20-50 atmospheres and at temperatures of 70-120 DEG  C. to produce nickel carbonyl.  The sintered matte is unaltered on exposure to air at temperatures below 200 DEG  C., and so need not be converted to carbonyl at once.ALSO:A material suitable for the preparation of nickel carbonyl by direct treatment with carbon monoxide is obtained by reducing a sintered nickel matte by heating it with a solid or liquid carbonaceous material.
