Abstract: 480,078. Steam locomotives. BUCHLI, J. June 15, 1937, No. 16566. Convention date, June 15, 1936. [Class 79 (i)] [Also in Group XXVI] A high-speed steam engine for locomotives is made up of two parallel cylinder blocks 1, the crankshafts 1a of which co-operate with an intervening drive shaft 5 through the intermediary of tooth gearing 4, 6, the arrangement being such that the crankshafts rotate in the same direction and the drive shaft 5 extends completely through the space between the two blocks. The shaft 5 may be the wheel axle or may be mounted on the locomotive frame and drive the wheel axle through any suitable coupling. Each driving axle of the locomotive may have its own driving unit. A shaft 3 is geared to the crankshaft and in turn to the cam shafts over each cylinder block. Corresponding cylinders of each of the two blocks are arranged with crankshafts at 180‹. The counter-shaft 5 and the crankshafts 1a are mounted within a common casing 2 which is built up with welded sheet metal plates. For facilitating dis-assembly the bottom casing is divided along a plane containing the shaft axes. Each crankshaft 1a has at both ends pinions 4 which engage with two large gear wheels 6 at the ends of the counter shaft 5 although a drive at one end only may be utilized. With uniflow engines the common exhaust chambers 12 are connected by a pipe 13 leading to the blast pipe.

Filed: 1963-04-30
Abstract: 1,057,043. Weighing apparatus. ULSTER PRINT WORKS Ltd. April 21, 1964 [April 30, 1963], No. 16867/63. Heading G1W. Weighing apparatus which is used for simultaneously weighing out N ingredients (where N # 3) in predetermined proportions by weight comprises a main balance beam which may be formed in two tandemed portions and two scalepan assemblies which consist of N scale pans and which are each supported on different balance arms of the beam, the scale pans being so arranged that when they are filled with their respective ingredients by an amount according to the required predetermined proportions the entire weighing apparatus is in balance. As shown in Fig. 1, a main beam is formed in two portions 10 and 11 which are each supported on fixed knife edges 13 and 20 respectively and which are pivotally connected together by a movable double knife edge 19. A container 14 movably attached to one arm of the beam 10 is, after being filled with one ingredient, balanced by adding two other ingredients to respective scale pans 23, 27 of the scale pan assembly acting on a pivot 21 at one end of the beam 11. The scale pan assembly comprises a beam 12 on which the scale pans 23 and 27 are so arranged that when the three ingredients are present in their respective scale pans in the required predetermined proportions, the total weight of the scale-pan assembly is balanced by the weight of ingredient in container 14 and the scale pans 23 and 27 containing the other ingredients are balanced on the beam 12. The scale pans 23, 27 are provided with hooks 32, 30 so that they can be secured in order to facilitate their filling. The required relative proportions of the three ingredients may be adjusted by suitably moving a counterweight 17 and knife edge 19 on the beam 11 simultaneously towards or away from knife edge 20 and/or by moving a counterweight 25 and scale pan 27 on the beam 12 simultaneously towards or away from knife edge 21. These simultaneous movements are each achieved by providing rotatable threaded rods 40, 45 Fig. 2, (not shown) each having oppositely threaded portions 40a, 40b and 45a, 45b to which the counterweight 17, knife edge 19, scale pan 27 and counterweight 25 are respectively attached.

Title: Improvements in or relating to synchronous electric striking clocks
IPC: G04C21/08
Filed: 1947-06-27
Abstract: 636,753. Electric clocks. BROWN, T. A., and PERIVALE CLOCK MANUFACTURING CO., Ltd. June 27, 1947, No. 16975. [Class 139] In a synchronous electric striking clock of the type in which the striking work includes a differential mechanism and rack striking mechanism the rack has a flat in place of the first tooth to provide for the striking of the half-hours and an abutment which, when the rack hook is lowered to engage the rack, disengages a locking member from the planet carrier of the differential mechanism. The hour strike rack 86, Fig. 1, is normally retained in its upper position by a lug 100 on the rack hook 94 which is provided with a pin 98 which normally bears against the face 81 of a change-over lever 78 carried by a shaft 74, Fig. 3, to which is also pivoted a locking arm 76 which, as described later, is periodically rocked into a position in which it engages and locks the carrier 57 of the differential mechanism which is carried by a shaft 68 on which the hammer actuated cam 72 is fixed. The rack hook 94 is controlled by the forked lifting piece 110 one arm of which co-operates in known manner with two ears 119, 120 on the minute spindle for hour and half-hour striking respectively. The arrangement is such that at a few minutes to the hour the lifting ear 119 lifts the lifting piece 110 the upper arm 116 of which lifts the rack hook 94 to allow the rack 86 to fall by gravity. At the same time a lug 124 on the arm 116 retains the change-over lever 78 and therefore the locking arm 76 in their normal positions. When, however, exactly at the hour, the lifting piece 110 falls, the locking arm 76 moves into locking engagement with the carrier 57 whereupon the shaft 68 rotates and the cam 72 effects striking and the gathering pallet 90 gathers the rack until once more it is engaged by the lug 100. At half-hours the operation is similar except that the lifting movement imparted by the lug 120 and the lifting piece 110 to the rack hook 94 is only sufficient for the lug 100 to clear a flat portion 102 equal to the width of one tooth provided at the front of the rack 86 which therefore only falls and is gathered through a distance corresponding to one tooth. The striking train is driven from a synchronous electric motor 28, Fig. 3. The supporting members are formed by a casting or moulding so as to be integral with the front plate 10 which may be a metal die-casting or may be composed of a thermosetting plastic material. Specifications 437,609 and 489,855 are referred to in the Provisional Specification.

Title: Improvements in or relating to x-ray detectable thread
Inventor: PRESTON JOHN MASSEY
IPC: A61K49/04
Filed: 1957-05-29
Abstract: Viscose rayon yarn having incorporated therein more than 50% (by weight of the yarn) of an X-ray detectable material is produced by adding an aqueous dispersion of an X-ray detectable material containing viscose as a stabilizer, in an amount which constitutes more than 50% by weight, and preferably not more than 65% of the final weight of the yarn, to viscose subsequently to the main viscose filtration but prior to the spinning machine filtration.  The diameter of the holes in the spinneret used may be over 100 microns and the particle diameter of the X-ray detectable material may be less than 5 microns.  The material may be pure barium sulphate.  The yarn may contain a coloured pigment in addition to the X-ray detectable material.  In an example, 7,9 parts by weight of a 60% w/w barium sulphate aqueous dispersion stabilized by about 5% of an ethylene oxide condensation product is diluted with 2,1 parts of soft water and 2,1 parts of a filtered viscose containing 7,5% of cellulose, 7,0% of sodium hydroxide and 2,38% of combined sulphur, and the slurry so prepared is continuously added in the proportion required to the main stream of filtered viscose having the same composition.  The mixture is homogenized and, after passage through swansdown spinning machine filters, is extruded through spinnerets having holes of 100 micron diameter into a spinning bath containing 9% of sulphuric acid, 4% of magnesium sulphate, 1% of zinc sulphate and 18% of sodium sulphate to give yarns containing over 50% and up to 64,2% of barium sulphate.
