Title: Barbituric acid antigens antibodies therefor and a method of assay of barbituric acid derivatives
IPC: C07K16/44
Filed: 1972-01-18
Abstract: 1327545 Immunological test for barbituric acid derivatives F HOFFMANN-LA ROCHE & CO AG 18 Jan 1972 [24 Aug 1971] 2405/72 Heading B1X [Also in Division A5] An antigen from which a diagnostic antibody can be prepared comprises a 2-substituted - 1,5-unsubstituted barbituric acid derivative coupled through the 5-substituent to a carrier material which is itself an antigen. The carrier material may be a polypeptide or protein coupled to the barbituric acid derivative through a peptide link. When injected into an animal this antigen produces an antiserum containing antibodies. Specific to the antigen or to the barbituric acid derivative by itself. A gamma globulin containing these antibodies may be isolated from this antiserum. In Examples an antigen is prepared by coupling 5-allyl-5-(beta-carboxy-alpha-methyl-ethyl) barbituric acid to bovine serum albumin or bovine gamma globulin. Antiserum is produced by injecting this antigen into New Zealand albino rabbits. A method of determining the amount of 5-substituted-1,3-unsubstituted barbituric acid derivatives in a sample comprises (a) adding the sample to a solution containing a known amount of labelled 5-substituted-1,3-unsubstituted barbituric acid derivative and an antibody specific for such barbituric acids, (b) measuring the proportion of labelled compound bound to the antibody and (c) comparing this value with a standard curve obtained by adding known amounts of labelled and unlabelled barbituric acid derivative to the antibody solution. The labelled barbituric acid may be C<SP>14</SP>-labelled pentobarbital, phenobanbital or barbital. The antibody may be produced as above. The antibodybarbituric acid complex may be precipitated by addition of saturated ammonium sulphate solution and the radioactivity determined by liquid scintillation counting.

[Classes 83 (ii) and 83 (iii)] Workhalders; jigs.-In a method of and apparatus for making forked-head screwed components particularly for straining-wires in aircraft construction, all the drilling operations are performed in a first jig and one of the transverse holes so made is then used to locate the component in a second jig in which the milling of the head is performed. The drilling jig, Fig. 1, has a clamping portion 3 for securing the cylindrical shank of the work 2 against a V-block member consisting of inserted pins 7, Fig. 3, with flats arranged at 90 degrees. The ends of the pins are also flatted and are engaged by corresponding flat surfaces on a bush 9 inserted in the end wall 1a. Guide bushes 12, 13 serve for the drilling of axial holes in the head and shank portions of the work. A transverse hole in the head is drilled through the bush 10 and a small inspection hole in the shank is drilled through bush 11. After drilling, the bush 13 is withdrawn and the end of the shank spot-faced by a tool inserted through the bush 9. Finally the hole in the shank is tapped. The component is then inserted in a multiple milling-jig which comprises a series of sliding pins 16 adapted to engage the transverse holes in the heads of the work pieces 2. The shanks are clamped in pairs by clamping members 17 which hold the work against flatted pins 18. The clamps are carried on bolts 19 having rectangular washers 21 which can be turned through 90 degrees so as to engage recesses in the block 15 to permit insertion of the work pieces. The heads of the work pieces are milled to the form shown in Fig. 9 by a gang of milling cutters 25, 26, Fig. 8. Ten or more pairs of components may be mounted on the jig which is carried on the machine table and as the components leave the milling cutters they may be replaced by fresh blanks.

Abstract: 675,744. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 5, 1951 [Feb. 11, 1950], No. 2798/51. Class 38 (ii). Stationary electrical induction apparatus (e.g. a transformer) of the type having a winding which includes a plurality of spirally wound disc coils 10 stacked in superposed relation and means for directing the flow of a cooling liquid, comprises a plurality of radial spacer members 20-29 positioned between adjacent coils to maintain ducts therebetween, a first insulating cylinder 9 spaced radially inwardly of the disc coils, a second insulating cylinder 12 spaced radially outwardly of the disc coils, the radial spacing members 20-29 alterntely abutting the first and second insulating cylinders 9, 12, each of the spacer members being spaced radially from that cylinder which it does not abut, in order that the cooling liquid flow is directed between the disc coils alternately radially inwardly and outwardly and around the ends of the spacer members through the spaces between the member and the insulating cylinder against which they do not abut. The cooling liquid enters the assembly via a conduit 17 flowing upwardly and across each disc coil simultaneously, leaving the assembly via a conduit 30. The flow of the liquid across each disc coil is constrained in two " parallel " paths, as indicated by the arrows in Fig. 2, due to a particular arrangement of the spacer members. The spacer members are U-shape in form (see Fig. 3), and have skewed slots formed therein to eliminate " dead " vortices such as 33, 34. By various arrangements of the radial spacer members and the provision of a number of spacing discs the cooling liquid may be directed over a number of disc coils in succession, i.e. a " series " flow, or around each disc coil in one direction only.

Title: Self-energizing single disc brake
IPC: F16D65/14
Filed: 1952-02-04
Abstract: 713,797. Disc brakes. WINGFOOT CORPORATION. Feb. 4, 1952 [Aug. 8, 1951], No. 2866/52. Class 103(1) A spot type disc brake having a self-energizing characteristic comprises a pair of substantially parallel levers 12, 13 pivoted at one pair of ends to a fixed member 10 and arranged to be moved together by fluid pressure or mechanical means acting through a tension member or bolt 22 that connects the other pair of ends, friction pads 17 being secured to the levers intermediately with surfaces parallel to the brake disc 5. If the rotation of the disc 5 is clockwise, as seen in Fig. 2 the friction pads 17 will, after application to the disc by a fluid pressure piston and cylinder 18, 19 or other means, be caused by the frictional drag to rotate the levers 12, 13 about their pivots 16 in such a way as to increase the braking force. As the pads 17 wear their mounting and friction faces tend to become more parallel. A U-shaped spring 27 anchored to the lever 13 at one end by a screw 28 has holes in its arms through which passes the bolt 22. When the brake is applied by drawing together the arms 12, 13 the free end of the spring 27 strikes the head of the screw 28 and allows the tension member 22 to slide through. When the brake is released spring 27 tends to open up so as to bind on the rod 22 and limit the separation of the levers.
