Title: Nuclear physics apparatus for generating magnetic fields
IPC: H01F6/00
Filed: 1960-10-28
Abstract: 934,946. Discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Oct. 28, 1960 [Dec. 28, 1959], No. 37112/60. Class 39 (1). [Also in Groups XIII and XXXV] In a nuclear physics apparatus including a magnet coil and a cryogenic plant 19 for cooling the coil to very low temperatures whereby the coil generates extremely high magnetic fields with a minimum expenditure of coil input energy, the coil comprises at least one helical layer 11 of conductor 12 which is connectable to a current source, is in heat conductive relation to the plant 19, and is of a material having a resistivity pt (T 0 ) at its cryogenic operating temperature T 0  for which the ratio is significantly less than one, where p s  is the resistivity of copper at ambient temperature, n is the plant efficiency, and T h  is the plant heat rejection temperature. Apparatus constructed in accordance with this expression is stated to provide that the energy lost in running the plant 19 does not exceed that saved in operating the coil at cryogenic instead of room temperature. The conductor may be of copper or aluminium, or of sodium if reinforced by a thin walled steel tubing 43 within which the sodium is cast, and the turn insulation is varnish. Each layer is structurally supported by a rigid cylinder 13 within which is an anodized wall structure 21 having longitudinal grooves 16 through which gaseous helium cooled by the plant 19 is circulated in a multilayer multipass flow from inlet conduit and manifold 24, 17 to outlet manifold and conduit 18, 26. Manifold rims 22a . . . 22f and spaces 23a ... 23d guide the coolant flow back and forth between the coil ends. The coil is thermally insulated by a shell 29 coated with aluminium in an evacuated space, and the leadin conductors 31, 32 may be cooled by a liquid nitrogen jacket, not shown, to prevent heat loss. Where the conductor 12 is of sodium the layers terminate in stubs 51 which are interconnected by jumpers 44 having sodium-filled apertures. The Specification describes the cryogenic plant and parameters of a typical coil.

Title: Method and apparatus for making Non-Woven Strand Structures
IPC: D04H3/04
Filed: 1967-08-15
Abstract: 1,194,564. Making wire netting. UNION CARBIDE CORP. 15 Aug., 1967 [16 Aug., 1966], No. 37358/67. Headings B3A and B3E. [Also in Divisions B5, F2 and D1] A net-like strand structure is made by looping strands around advancing rows of pins 18, 19 using a carrier member 45 oscillating between the rows and carrying the strands in a curvilinear path in a looping zone. During looping the strands are advanced by accelerating feed tube shaft 24 (when the strands have passed the middle of the oscillation path toward one row of pins 18 or 19) to the speed of the pins 18 or 19; then they are passed outwardly between the pins, accelerated in a forward or backward direction with respect to the pins and passed inwardly between the pins then retracted until the strands have reached the middle of their oscillation path in the opposite direction. Looping of strands around pins is achieved by flipping the strand feed tubes 21 between the pins when the carrier member 45 is at the end of its oscillation. The flipping action is caused by linkages (83-116), see Figs. 1 and 6, not shown. Acceleration of strands is achieved by the linkages (136-166), see in Fig. 7 (not shown) acting on the end of feed tube shaft 24. This shaft is suspended from bridge 40 of carrier member 45 and is free to reciprocate axially under the action of the above linkages. Advancement and retardation of the strands to the speed of the chains is achieved by crank arm 25 acting on part 40 of the carrier member. The bridges 40 are free to reciprocate relative to the carrier members 45 along rods 41. The strands can be made of organic or inorganic fibre, filament, cord or wire. The net can be coated with adhesive and used to reinforce paper, plastics and foil. The netting can be stretched and then laminated to or between adhesive coated paper, plastics or foil as it leaves the looping apparatus, see Figs. 1, 2 and 3, not shown.

Title: Improvements in or relating to joints for stranded electric conductors
IPC: H01R4/02
Filed: 1946-12-23
Abstract: 619,741. Soldering electric conductors. STANDARD TELEPHONES & CABLES, Ltd., and SEYMOUR, R. E. Dec. 23, 1946, No. 37760. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] In a method of jointing two multiple stranded conductors 1, 2, the outer wires 26, Fig. 4, of each conductor are first spread by forcing a spreader comprising a steel tube 7 having a tapered conical end 9 into the end of each conductor. The spreader is then replaced by a strand protector 20, Fig. 5, of similar construction to the spreader but having thinner walls. A strand cutting guide consisting of a split die 14, 15 with a circular bore 16 is clamped over the outer wires by bolts 17 after which the portions of the outer wires between the cutting guide and the end of the conductor are cut off and the cutting guide and strand protector removed. A tubular metal ferrule 22 is then placed over the ends of the prepared conductors by further spreading the outer wires of one conductor 1 as shown in Fig. 6 and sliding the ferrule completely on the inner wires 23 whereupon the two conductors are brought into abutting engagement and the ferrule slid back so as to contain both the conductor ends. The outer wires of conductor 1 are pressed back into place and solder poured through holes 21 in the ferrule and also on the ends thereof. The ferrule may be split longitudinally into two semi-cylindrical portions. Where the stranded conductors are not of circular cross-section they are first brought to this shape by forcing over them for a short distance a strand forming tool consisting of a length of steel tube, Fig. 11 (not shown). The jointing method described above may be used in making a barrier joint as described in Specification 568,643, [Group XXXVI].

Patent GB-381158-A (GB)
Abstract: 381,158. Typewriting computing- machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Elliott-Fisher Co. ; Cedar Street, Harrisburg, Pennsylvania, U.S.A.) June 24, 1931, No. 18297. [Class 106 (i).] With several totalizers.-A machine has different categories of fixed column totalizers and corresponding categories of travelling line totalizers and the means provided for actuating the totalizers in correct relation takes account of different spacings of the two classes of totalizers. The invention is described as applied to the Elllott-Fisher machine, 28, 29 being stationary column totalizers allotted respectively to items of quantity and value, and 33, 34 being corresponding line totalizers. The latter are arranged in close juxtaposition with say only one blank step between them whereas the column totalizers, due to their frames, are separated by two such steps. To allow for this difference of spacing the line actuator 16 is controlled through shaft 14 by a spring-impelled slide 37, Fig. 4, mounted between plates 36 on the carriage and carrying coupling hooks 44 to engage lugs 43 on the column totalizers. One hook and lug are in one vertical plane and the others in a different vertical plane and the lugs are spaced differently from the hooks in the direction of travel, by one digit space. Thus when an item has been entered in the quantity totalizers 28, 33 the next advance of the carriage, operating through cam slot 50 in one plate 36 and pin 48, uncouples one hook 44 whereupon the slide 37 responding to spring 39 jumps forward until its second hook meets the lug of totalizer 29, the actuator 16 consequently receiving relatively backward displacement to re-establish unison with the column actuator 3 for entering the next item in the totalizers 29, 34. The line totalizers may be put out of action by imparting to the slide an extra step of advancement so as to depress the hooks by means of the other ends of the cam slots 50. This adjustment is effected by a finger lever 54, Fig. 14, having a slotted sector to displace through a crank arm 61 the actuator shaft 14 and therefore the slide, the sector being then retained by a detent 57. Operation of the finger lever except when the slide is in normal position is prevented by a pawl 65 controlled by the crank arm 61. In order to lock the numeral keys while the actuator 16 is between the two totalizers or beyond the second, the usual crowding lock is controlled by a slidable bar 68, Fig. 9, furnished with lugs 74 adapted to be engaged by a weighted pawl 75 carried by the actuator 16. When the latter arrives between the two totalizers the pawl engages a lug to displace the bar and is then immediately rocked by a relatively stationary pin 79 to ride upon the lug. The bar is latched in displaced position by a detent 80 operated to free the bar again by the depression of the usual transfer restoring key 19. The bar is similarly displaced when the actuator passes beyond the totalizers. Specifications 266,469, 267,045, [both in Class 106 (i), Calculating &c.], 373,131, and 373,157 are referred to.
