Abstract: 383,232. Gas turbines. HOLZWARTH, H., 7, Goethestrasse, Dusseldorf, Germany. July 4, 1932, No. 18919. [Class 110 (iii).] Turbine blades are cooled by water which flows through one or more chambers built in the periphery of the wheel between the forked roots of the blades. The chambers 6 are formed as flat resilient copper tubes and to obtain good conductivity they are soldered to the roots of the blades. The whole structure is made rigid by keys 9 which taper in the driving direction and in a direction parallel to the axis of the rotor. Instead of the provision of separate chambers for each of the blades, annular chambers with inlets and outlets through conical pins 13, Fig. 3, may be provided. The blades are provided with one or more copper cores 26, Fig. 7, which may be cut away at 27 so that heat is conducted away from the tip of the blade more readily than from the cooler centre part. The chambers may be formed integral with the wheel by turning over flanges 28, Fig. 12, to meet at 30.

Title: Improvements in or relating to track switching devices
Inventor: MEEKINS WILLIAM THOMAS GORDON
IPC: E01B25/12
Filed: 1953-07-13
Abstract: 756,742. Track switching device. CLARKE ELLARD ENGINEERING CO., Ltd. July 13, 1954 [July 13, 1953], No. 19365/53. Classes 104 (1) and 104 (2). A track switching device having a movable track section supported on wheels running in paths in which gaps are provided for the purpose of lowering the track section on to a firm support when it arrives at a position of alignment with a track along which a load is to run has the movable track section carried on a number of wheels which are spaced apart in the direction of the wheel path and which support the section through the intermediary of a rocker pivoted to the section which lowers the latter on to the firm support by a rocking movement when the first wheel falls into the gap. The Figures show the application to an overhead conveyer system in which trolleys run on the lower flanges of I-section track members. The track section 1 pivoted at one end to the main track 3 is movable between tracks 5, 6 by means of rollers 8, 9 running on a plate 4 and attached to a rocker plate 10 pivoted at 11 to a bracket 7 mounted at the other end of the section 1. Two holes 16, 17 are cut in the plate 4 adjacent the tracks 5, 6 and the arrangement is such that when the section 1 is aligned with the track 5 or 6 the roller 8 or 9 falls into the hole 16 or 17 and so lowers the bracket 7 on to the plate 4 whereby section 1 is firmly supported in position against accidental movement. The track section 1 is moved from one position to the other by wires or pull-strings 12, 13 attached to the top of the rocker plate 10. The wire 13 on being pulled to move the track section to the right of Fig. 3 tilts the rocker plate 10 about the roller 9 so as to lift the roller 8 out of the hole 16 and to lift the bracket 7 clear of the plate 4. Both rollers 8, 9 support the track section 1 as they are moved over the plate 4 until the roller 9 falls into the hole 17 and the bracket 7 is lowered on to the plate 4 and supports the track section 1 in alignment with the track 6. The track section 1 is pivoted about pins 18, 19 the upper pin 18 of which bears on a ball bearing 20 and the lower pin 19 loosely engages a hole to allow a small tilting movement when the bracket 7 is lifted clear of the plate 4. Baffle plates 21, 22 supported by stays 23, 24 are carried by the track section 1 to enable the open track 5 or 6 to be blocked when the track section 1 is aligned with the track 6 or 5. A modification is described for use with a threeway switch, Fig. 4 (not shown), in which three holes are provided in the plate 4 and three rollers are mounted on the rocker plate 10.

Title: Improvements in connection with electromagnetically operated switches or circuit-controlling devices
IPC: H01H50/20
Filed: 1935-07-08
Abstract: 459,717. Electromagnetic switches. EVANS, C. J., and EVANS, S. C., 99, London Road North, Lowestoft. July 8, 1935, No. 19419. [Class 38 (v)] In an electromagnetic switch for controlling one or more electric circuits which comprises two solenoids arranged to transmit motion in opposite directions to a common core, the movements of the core producing an interruption in the current supply to the operating solenoid after it has effected the required movement of the core, the means for controlling the switch contacts are arranged to operate between the two solenoids. As shown, the two solenoids 68, 70 have a common core 64 slidably mounted within them, an arm 29 bearing a contact-operating projection 79 being attached to the core and arranged to operate between the adjacent but separated ends of the solenoids. A series of sets of cooperating spring contacts 73, 85 76, 88 are arranged to be engaged and separated by the insulating projection at the ends of its travel, one or more of such contact sets being connected in controlled circuits and the remainder in the solenoid circuits in such a manner that when the circuit of either solenoid is completed the consequent movement of the core breaks the circuit of the operating solenoid and prepares the circuit of the other solenoid. In an alternative arrangement also described, Figs. 5 and 6, (not shown) the core normally assumes a position midway between the two solenoids, the contacts being so arranged that movement may be effected in one or more stages in opposite directions from this central position. At the ends of its travel, the core engages a fixed magnetic core 67 or 69. The contacts are carried on an insulating base 27 through which the operating rod 29 projects.

Abstract: 643,872. Blasting cartridges; explosives. ATLAS POWDER CO. July 21, 1947, No. 19451. Convention date, Dec. 26, 1944. [Classes 9 (i) and 9 (ii)] A blasting cartridge has a paper case 11 crimped over a sensitized explosive charge 13 of coarse-grained ammonium nitrate composition with a central core 15 of paper-wrapped gelatinized nitroglycerine dynamite, the composition of the charge and the proportions of core to charge being chosen to give maximum blasting strength without the evolution of red fumes. In an example the main explosive composition was nitroglycerine 5 per cent, coarse ammonium nitrate (95 per cent passing a No. 10 U.S. standard screen, not more than 40 per cent passing a No. 35 screen and not more than 5 per cent passing a No. 70 screen) 84 per cent, ground soft coal 2 per cent, ground sawdust 1.5 per cent, ground apricot stones 7 per cent and calcium carbonate 0.5 per cent, percentages being by weight. The rate of detonation for this composition was 4,200 f.s. when initiated by a No. 6 blasting cap. The composition was packed in cartridges of 5¢ in. diameter and 21¢ in. long with a 1“ in diameter core of 30 per cent ammonia gelatine dynamite having a detonation velocity of 7,900 f.s. An alternative composition is given.

Title: Improvements in tabulating devices for single type composing and casting machines
IPC: B41B7/04
Filed: 1923-07-30
Abstract: 206,478. Garda, E. Nov. 4, 1922, [Convention date]. Strip-perforating machines; justifying type.-A device for facilitating the composition of tabular matter in single-type composing and casting machines comprises a rotatable drum 1, Fig. 1, carrying parallel screws 4 on which are adjustable nuts 5 forming stops for the line-measuring rack 13 of the machine, the drum being rotated a step to bring a new stop into position as each measure or section of the line is completed. The nuts 5 are each provided with a hinged cap portion 6, Fig. 19, to facilitate adjustment along the screw, the cap being held closed by a socket 8, which screws on to a bearing 5<a> and engages a conical part of the nut. The screws are rotated to adjust the nuts exactly by means of a spring- pressed screw-driver 9, Fig. 1, which can engage slots in the ends of the screws. The drum is rotated by means of a ratchet-wheel 14 having driving and retaining pawls 15, 16, and is connected by bevel-gears to an index 26 moving over a disc 27. A bar 29, which lies in the path of the index 26, is adjusted on the disc in accordance with the number of measures in the fine, and the disc 27 gears with a distributing disc 39 the rotation of which is limited by a pin 40, Fig. 2. The line-measuring rack 13 carries a hinged arm 12 adapted to engage the stops 5 on the drum, and is operated in known manner by a motor-rack 32 and air-cylinders 35, 36. After the composition of each section of the line, a key 48, Fig. 2, is depressed and air is admitted to a cylinder 42, the piston 18 of which actuates the feed-pawl 15 and rotates the drum one step. The movement of the piston 18 uncovers a passage 50 leading to the air-cylinder 36 whereby the rack 13 is returned into contact with the next stop 5. After the last section of the line has been composed, the index 26 engages the bar 29 and rotates the discs 27, 39. Depression of the key 48 then admits air to a cylinder 43 as well as to the cylinder 42, whereupon a cam 20 retracts the pawls 15, 16 and permits the drum to be returned to initial position by a spring. Air is also conducted by a pipe 52 to a valve 44, which prevents re-setting of the rack 13 until the drum has returned. The index 26 geared to the drum rotates the discs 27, 39 back to their initial positions, so that air is cut off from the cylinder 43, the valve 44 is opened by a spring, and the rack 13 is returned by the action of air passing through the passage 50.
