Filed: 1918-07-12
Abstract: 119,444. Bosch Magneto Co., (Assignees of Norman, F. D., and Schwarzmann, W. E.). Sept. 21, 1917, [Convention date]. Magnetos, driving. - Trip or accelerating mechanism for actuating the ignition magneto of an internal - combustion engine at starting, and for other purposes, comprises two disks, one disk 13 being fast on the driving-shaft 11 and having two posts 14 on its face, and the other disk 23 being fast on the magneto shaft 12 and having a heavy flanged rim 24. A sleeve 15 loosely mounted on the enlarged end 16 of the shaft 11 has two arms 17 which fit into slots 26 in the rim 24. Two main springs 18 and two buffer springs 19 abut the posts 14 and arms 17, these parts being held together by a ring 20. The disk 13 has two releasing cams 22 normally displaced from the arms 17; safety cams 25 are formed also on the periphery of the disk 23. A pawl 28 is loosely journaled on a stud 29 which has an operating handle 30 and a crank-arm 31 fast on it. The stud rests in bearings in a casing 42; a spring 32 holds the stud and handle in the position shown in Figs. 3 and 4. The rotation of the pawl 28 is limited by shoulders 33, 34 on the adjacent faces of the pawl and crank-arm, the rotation of the crank-arms being limited by the stop-pin 35. With the handle 30 in the position shown, the pawl may rest either on the rim 24, Fig. 3, or it may be held away by a latch 37, as shown in dotted lines in Fig. 4. The latch consists of a spring-pressed part 37 loosely mounted on a stud 38 and carrying a spring-pressed finger 39. The pawl has a squared part 40, Fig. 5, to lock the protruding ends of the arms 17 and a bevelled part 41 to co-operate with the finger 39. At starting, the pawl 28 engages an arm 17 to lock the shaft 12 against rotation while the shaft 11 is being rotated; the pawl is afterwards released by a cam 22, causing a sudden rotation of the shaft 12. The cams throw the pawl into the latched position out of the path of the arms 17. The position of parts of the mechanism may be changed for driving the magneto in the opposite direction. With this object, the pawl 28 is set on the other side of its stud 29, the latch 37 is mounted at the opposite corner 48 of the casing 42, the pin 35 is set at the other side of the stud, and the arms 17 are set in other slots 27 in the rims 24, the springs also being re-arranged.

Title: Improvements in or relating to apparatus for cleaning objects by means of condensingvapour
IPC: C23G5/04
Filed: 1949-04-29
Abstract: <PICT:0679717/III/1> In known vapour degreasing apparatus comprising an open container 1 with the usual cooling coil in its upper part to delimit a vapour zone wherein the articles to be degreased are supported, the container being divided at its bottom by a partition 2 into a heating compartment 3 and a condensate receiving compartment 4, and means being provided to convey condensate precipitated on the container walls to the compartment 4 and to convey condensate flowing down from the articles to the compartment 3, the ratio between the volumes of the two compartments from the bottoms thereof up to the overflow level formed by the partition is arranged such that with a normal quantity of liquid the heating compartment can receive the liquid quantity of the entire condensation compartment without the level of the total quantity of liquid rising so high as to cause liquid from the heating compartment to return over the partition to the condensation compartment.  The dirty solvent from the articles being cleansed is thus kept separate from the pure solvent precipitated on the walls; also only a part of the total solvent requires to be heated and at the same time a reservoir of pure solvent is available for other purposes.  In the form shown, the heating compartment 3 is provided with heaters 7, and with a protecting perforated plate 10 spaced from the container walls to allow condensate flowing down the walls above this compartment to collect in a channel 8 therebelow, which channel extends along the walls of the container as far as the partition 2 and slopes towards the condensate-receiving compartment 4.  The compartment 4 is provided with a sloping guide plate 9 resting on the plate 10, also spaced from the container walls to allow condensate flowing down the walls above this compartment to pass directly thereto.  Dirty condensate from the articles being cleaned is diverted by the guide plate 9 into the heating compartment 3.  The compartment 3 is of sufficient volume to hold all of the starting volume of solvent, and the respective volumes of the compartments 3 and 4 are preferably such that when the compartment 4 is full and liquid overflows the partition 2, the liquid level in the compartment 3 is still above the heaters 7.  The apparatus may be emptied of solvent by first removing the latter from the compartment 4 through a pipe 14 by means of a pump 12, continuing the heating of the dirty solvent in the compartment 3 as long as desirable, withdrawing the additional solvent collected in the compartment 4, and then drawing the contaminated liquid direct from the bottom of the heating compartment.  The pure solvent in the compartment 4 may be used for flushing the articles being cleaned by connecting the pump 12 to a hose pipe 16 provided with a flushing nozzle 17 Specification 679,718 is referred to.

IPC: B61L1/18
Abstract: 115,239. McKenzie, Holland, & Westinghouse Power Signal Co., (Assignees of Saunders, J. E.). April 26, 1917, [Convention date]. Electrical systems, automatic.-In alternating- current signalling systems for use on tracks in which the track rails serve to carry both propulsion and signalling currents, impedance bonds of a special character are used at the ends of the insulated sections in order to obtain efficiency and economy of current. Fig. 2 shows an improved bond connected to the rails RR' of one section of track. A similar bond connected to the adjacent rails at the other side of the insulated joints 2 is connected to that shown by the wire 9. Each bond includes the usual impedance winding @, and, according to the invention, a second winding 10 in series with a condenser 11 is wound on the core and a yoke 12 with air gaps 12a provides a magnetic leakage circuit. The capacity 11 and the air gaps 12a are adjusted to provide the equivalent of a resonant circuit at the frequency of the propulsion current in parallel to the winding 8<a>. By this means, any currents in the winding 8<a> due to unbalanced propulsion currents in the two rails are prevented from passing to the track rails and relays. A third winding 13 is added to the core 7<a> and is connected to a capacity 14, adjusted to form a circuit resonant at the frequency of the signalling current either alone or in conjunction with the track relays and track circuit. This short circuit is intended to produce the conditions of. greatest economy of signalling current.

Title: Folding machine for piling fabric in superposed folds preparatory to simultaneous cutting of the various folds according to a pattern
IPC: B65H45/103
Filed: 1956-04-17
Abstract: 794,463. Folding fabrics. SOC. PER AZIONI VIRGINIO RIMOLDI & CO. April 17, 1956 [Sept. 24, 1955], No. 11685/56. Class 42 (2). A machine for laying fabric in superposed folds comprises carriage reciprocating over an adjustable path on a table, the carriage having a motor 5, Fig. 3, driving through a chain drive the carriage wheels 3 and through further drives a pair of top rollers 7, 8 unwinding the fabric T from a roll 6 and a pair of lower rollers 24, 25 delivering the fabric on to the table. As shown, motor 5 is reversed at the ends of the carriage travel when a depending lever 101, Fig. 10, engages adjustable abutments on the table. Motor 5 drives, through worm gearing 11, 12, a friction clutch and a dog clutch, a shaft 13 which drives wheels 3 via a chain 15; the friction clutch damps shocks occurring on reversal of carriage travel. Shaft 13 also drives, through variable-speed pulley and belt gearing 18, 19, 20, a shaft 21 connected, through epicyclic trains, to two shafts 22, 23. The drive from shaft 21 to the two epicyclic trains is conveyed by two separate gear trains driving oppositely-directed one-way clutches, so that the direction of rotation of shafts 22, 23 is unaltered by reversal of motor 5. Shaft 22 drives, via a chain 9, fabric feed-rollers 7, 8, and shaft 23 drives, via chains 32, 40, fabric delivery rollers 24, 25. The planet-carriers of the epicyclic trains are normally held stationary by lock pawls, but can be rotated manually by cranks to effect an instantaneous angular displacement of rollers 7, 8 relative to rollers 24, 25 to vary the length of fabric stock R maintained in a loop following roller 8. Rollers 24, 25 are automatically lifted a small adjustable distance, corresponding to the fabric thickness, at each carriage reversal. Lever 101 carries a cam 123 acting on a follower 122 on a rod 121 connected through a one-way clutch to a shaft 116 carrying a pinion 115 meshing with a rack 114 on the bearings 111 of rollers 24, 25, the bearings being slidable vertically on bars 113. Shaft 116 can also be rotated manually by a hand wheel via a dog clutch. The extent of movement of rod 121, and hence of rollers 24, 25, at each movement of lever 101 is controlled by means of an adjustable eccentric stop-pin 128. Movement of rod 121 also operates, through a link 132, pawls 134, 135 of a counter-mechanism which records the number of travels of the carriage. A flat surface at the rear of the carriage, and additional guide rollers at the top, permit of fabric feed from a pile instead of a roll.

Abstract: 1521346 Super-conductors BBC BROWN BOVERI & CO Ltd 24 March 1976 [26 March 1975] 11902/76 Heading C7D [Also in Divisions B3 and H1] A method of making a stabilized super-conductor containing filaments of super-conductive material in which a composite slug is mechanically deformed followed by the formation of superconductive filaments by the diffusion of at least one material in the matrix into a second material in filament form in the conductor, in which the middle region of the slug is provided with rods or wires 2 of the second material which are surrounded by a material 3 containing the diffusible material, and in the outer region wires or rods 4 of good electric conductivity which are surrounded individually or in groups with a diffusion-blocking barrier material 6 and a high resistance layer 5. Material 2 is of niobium, material 3 of bronze, material 4 is copper, material 5 of a copper-nickel alloy, and material 6 is tantalum. The diffusible material is tin. The conductor is surrounded with a tube 1 of copper-nickel alloy, brass or copperaluminium alloy. The slug is hot and/or cold worked into a wire with niobium filaments, with intermediate anneals if necessary for softening the bronze. The super-conductive compound Nb3Sn is formed by annealing the wire at between 500 and 900C to cause diffusion of the tin from bronze block 3 into the surface of the niobium filaments. Cylinder 1 may be removed by pickling in acid. In a second embodiment, Fig. 2 (not shown), niobium rods are in bronze tubes packed together, and are surrounded by copper rods in highresistance copper-nickel alloy and diffusionblocking tantalum layers, the whole being inserted into a brass cylinder and processed as above. Super-conductors V 3 Ga and V 3 Si may be made in a similar way. In place of niobium rods 2 or bronze tubes (7, Fig. 2), niobium rods in a copper or bronze matrix may be used and may be surrounded by a high-resistance layer 8 or (8'). Copper rods 4 may be surrounded by a material both diffusion-blocking and of high-resistance e.g. TaV alloy or TaNb alloy. Rods 4 may be further sub-divided by high-resistance layers. In Fig. 3 (not shown) the diffusion-material containing matrix 10 also extends between and outside the rods 4 so that the principal part of the matrix is on the outside of the slug and removed after the super-conductive material is formed, e.g. by pickling in acid.
