Title: Improvements in ignition distributors
IPC: F02P7/00
Filed: 1923-08-23
Abstract: 226,578. Ford, H., and Taylor, G. H. Aug. 23, 1923. Rotary distributors ; contacts.-In an ignition distributor having fixed contacts in the form of balls E - - E<3> spring pressed inwardly in a radial direction, the rotary contact member consists of an insulating cylinder I' in the periphery of which is dovetailed a steel contact F<4>, the balls E - - E<3> being arranged in separate planes perpendicular to the distributor axis so that each abuts on a separate track on the rotor. The balls E - - E' are housed in metal tubes B which are held in the insulating annulus C and are formed integral with insulated terminal screws B<1> projecting through the distributor casing A. Each ball is pressed against the rotating contact-carrying cylinder F by a spring H so that the contact F<4> engages the balls in succession. The contact F<4> has a lateral extension screwed at F<5> to the brass sleeve F' mounted on the distributor shaft G. Specifications 187,120 and 207,075 are referred to.

Title: Improvements in joints for electric cables
Inventor: RUSSEK ROMAN MARIAN
IPC: H02G15/196
Filed: 1951-09-11
Abstract: 701,828. Cable joints. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 10, 1952 [Sept. 11, 1951], No. 21393/51. Addition to 583,642. Class 38 (1) In a modification of the cable joint according  to the parent Specification each of all or most of the insulating strips forming parts of the insulation of one cable length has a lay of opposite hand to that of the directly-underlying strip forming part of the insulation of the other cable length. Thus in Fig. 1 the strips a1, a2, a3 ... forming the insulations of cable length a are lapped in one direction and those b1, b2, b3 . . . of cable length b are lapped in the opposite direction, the butt joints c1, c2, c3 . . . in successive layers being arranged so that they are out of register. Where the cable is constructed with the strips applied in groups of, say, six, the lay of the strips in one group being of opposite hand to the lay of the strips in the next group, it is arranged that in cable lengths to be joined, corresponding groups of strips are of opposite lay Fig. 2 (not shown). In such a joint the first layer of each group on one cable length will have the same lay as that of the strip of the other cable length forming the last layer of the preceding group but it is stated that where there are several strips per group this is not detrimental. It can, however be avoided in a joint according to Fig. 3 by arranging that the change-over from one direction of lay to the other occurs in one cable length one layer later (or earlier) than in the cable length to be jointed to it. Thus strips a2 . . . a7 are of opposite lay to a1 and strips b1 ... b6 are of opposite lay to a2 . . . a7. The locations of the butt joints c1, c2, c7, c8, c13, c14 are arranged so that the strip belonging to cable length a in each of these layers overlaps the strip belonging to cable length b of opposite lay in the previous layer, e.g. a2 overlaps b1.

[Class 86] In stirring apparatus for mixing tarmacadam, asphalt and other road surfacing materials, of the kind in which the stirrers comprise a series of stirrer arms which have bosses shaped to fit on a square shaft radially at 45 degrees to each other and each held in position by means of a cap and two bolts, and in which each stirrer arm has a weartaking tip, the tip is slidable axially of the arm and means is provided for locking the tip on the arm in axially adjusted position. A stirrer arm b, Fig. 2, is fashioned with a tapered rib b<1> to engage with a longitudinal undercut groove a<1>, Fig..4, formed in a tip a. The latter is secured by a countersunk bolt which passes through a square necked hole a<3> in the member a and engages an opposed pair of serrations b', Fig. 5, in a slot b<2> in the rib b'. The tip a abuts against a shoulder a<2> on the arm b, and when the tip becomes worn it is moved along the arm and the securing bolt is passed through another pair of serrations b<3>, a shim having been placed between the shoulder and the tip. The stirrer arms are secured by bolts f and a clamping plate e to a shaft d radially at 45 degrees to each other. Two parallel shafts may be arranged side by side, the extremities of the arms on each shaft forming a right and left hand spiral, and the shafts may be rotated in opposite directions so that the material is passed from the mixer ends,to the centre of the mixer. To protect the arms at the ends of the shafts from any abrasive action due to the material being mixed the caps e securing the end arms to the shafts are each formed with a disc through which each end of the shaft is passed.
