Title: Improvements in power transmission mechanism of vehicles
IPC: F16D3/70
Filed: 1947-07-24
Abstract: 625,376. Universal joints. LE CLAIR, L. J. July 24, 1947, No. 19978. [Classes 80 (ii) and 80 (iv)] [Also in Group XXXI] In a vehicle having a pair of wheels on a common axle, resiliently mounted to tilt laterally relatively to the frame, which latter has a driving member constrained to rotate about a substantially fixed transverse axis, a hollow power transmitting member driven from the driving member and universally coupled to a wheel, surrounds the axle and is journalled in a gear case for rotation about a second transverse axis, the gear case being restrained to rock about an axis on or parallel and close to, the driving member axis. The shaft 24 of a driving motor 17 mounted by rubber bushes at 18, 19, 20 to the vehicle frame carries a gear 25 meshing with a gear 26 rigid with a hollow shaft 27 journalled in bearings 34, 35 in a gear case 28. The gear case is journalled on the bearings 32, 33 on the shaft 24, and is restrained to movement in a vertical plane by horns 39 bearing on rubbing pads 40 on the casing. The shaft 27 surrounds the axle 12 and has a flange 36 connected to a wheel 10 by axial pins 37 co-operating with rubber bushes 38 in the wheel. One half of the gear case is divided along a horizontal plane and the other half in a vertical plane for strength. In a modification the gear case is journalled on the motor casing and is restrained to movement in the vertical plane by a swinging link, the driven gear being journalled on an inwardly projecting flange of the gear case. In another modification the axle is constrained to move in an arc by a radius rod and the gear case is pivoted about the same axis which is parallel and adjacent the motor axis.

Filed: 1960-06-08
Abstract: 952,338. Travelling wave tubes. STANDARD TELEPHONES & CABLES Ltd. June 8, 1960, No. 20062/60. Addition to 906,206. Heading H1D. In a travelling wave tube the delay line is a plurality of gratings 5, Fig. 1, curved out of the plane of their edges and disposed between and secured to side walls 4 and to one another. Preferably at least two of the gratings are oppositely curved so as to be flooded by, yet conform to, a solid cylindrical electron beam. There may be four or six gratings which may be fabricated out of thin molybdenum sheet and clamped or brazed between stainless steel sidewalls. To couple to a waveguide feeder end grating conductors are joined together, bent out and led through the waveguide wall so as to terminate in a probe within a hollow waveguide Fig. 2 (not shown). The grating conductors may be thicker at their ends than at their middle, Fig. 4 (not shown). The delay line may be used in a backward wave oscillator, Fig. 3 (not shown). One grating or set of gratings can give backward wave interaction and a second grating or set of gratings forward wave vibration as in Specification 805,933. The backward wave grating or set of gratings may have reflectionless terminations of lossy coatings. An axial magnetic field focuses the beam.

Title: Process for preparing polynucleotides
IPC: C07H21/00
Filed: 1962-05-24
Abstract: Polynucleotides are made by contacting nucleotides or nucleosides with a polyphosphoric acid alkyl ester.  Reaction may be effected at 20-60 DEG  C., possibly in the presence of a tertiary cyclic nitrogen base, whereafter the reaction mixture may be dissolved in water and dialysed against water to remove orthophosphate and oligonucleotides. The polynucleotide may then be isolated from the solution by lyophilization or precipitation with alcohol. Examples describe the preparation of (1) and (2) polyadenylic acid from adenosine-21-monophosphate and adenosine-31-monophosphate or from adenosine; (3) polythymidylic acid from 21 - desoxythymidine - 51 - phosphate; (4) polycytidylic acid from cytidylic acid; (5) polyuridylic acid from uridylic acid; (6) polyguanylic acid from guanylic acid.  Uses: As inhibitors for bacteria, for the production of virus mutants or increasing the antigen titer.

Title: Improvements in or relating to positioning fish
IPC: A22C25/12
Filed: 1946-07-05
Abstract: 618,463. Fish dressing. ARENCO AKTIEBOLAG. July 5, 1946, No. 20189. Convention date, April 17, 1945. [Class 28 (ii)] Fish are arranged or positioned with their heads pointing at least in one direction as in Specification 590,138 by an oscillating plate which engages and pushes the fish head first, the plate being also free to move transversely of the fish, i.e. descend and thereby to keep in engagement with and push the fish head first step by step. The positioning is done by the to-and-fro action of an oscillating plate 65 which is also free to descend on the fish, the lower edge 87 of the plate being inclined to and bearing on the fish. Thereby the fish is pushed outwards step by step until the requisite thinner part at the tail comes under the edge which has descended to a set limit and so ceases to have any more outward push on the fish. At this stage the conveyer 1a has carried the fish to the tail cutting off wheel 90. The plate 65 is oscillated about its pivot pin 67 through a cam 80. Slot 69 for the pivot pin 68 allows a plate 65 to descend gradually as allowed by the contact of the fish body with its lower sloping edge. The plate can descend until its top 91 engages the stop piece of the lever. The fish are thereby arranged in one or two transverse groups on a conveyer with their heads pointing outwardly at one or both sides. Beheading wheel-cutters 18 are adjusted at the desired distance from the tail cutter 90 to cut off the heads and leave the required length of fish body.
