Abstract: A change-speed gear having high and low speed ranges comprises coaxial input and output shafts 11, 12, a parallel layshaft 13, a gear 14 fast on the input shaft and constantly meshing a gear 15 free on and clutchable to the layshaft, a gear 17 fast on the layshaft and constantly meshing a gear 16 rotationally free coaxially of the input output shafts and clutchable to either or both of said shafts, and gears 18-21 fast on the layshaft and constantly meshing gears 118-121 free on and clutchable to the output shaft. The gear 16 may berotatably mounted on the end of the input or, as shown, the output shaft. The pitch circle diameter of either one of the gears 14, 16 exceeds that of the other. Positive clutch sleeves 30, 31, respectively for clutching the gears 16, 17 to the input shaft and the layshaft, are axially slidable by forks (32), (33) interconnected by a lever (34) to ensure the engagement of only one of these clutches at a time, the forks being operated by a piston (37) actuated pneumatically or hydraulically under the control of a valve which is Bowden-cable operated by a gear-shift levermounted push-pull button. A reverse idler shaft (22) has free thereon and clutchable thereto a gear (23) constantly meshing a gear 24 fast on the layshaft, and a gear (25) fast thereon meshing a gear 26 splined on the output shaft and integral with a positive clutch sleeve 42. Positive clutch sleeves 40, 41 and the sleeve 42, respectively for clutching the gears 16, 118 and 119, 120 and 21, to the output shaft are axially slidable, from neutral positions, by forks 140- 142 fast on shift rods 43-45. A clutch sleeve (49) for clutching the gear (23) to the reverse idler shaft is axially slidable, from a neutral position, by a fork (48) connected by a lever (47) to a shift rod (46). The shift rods are selectively shiftable by a gear-shift-lever-actuable, rotatable (cross-shift) and slidable (gear-establishment), spindle 56 having an arm 55 the end of which is engageable in grooves of members 50 carried by the shift rods. A T-sectioned interlock member 52 engaging the grooves of the members 50 and movable with the arm 55 during cross-shift prevents simultaneous gearestablishing movement of more than one shift rod.

Title: Safety device for limiting the amount of gas discharged from a container containing a liquefied gas to a predetermined volume
Inventor: BAGNULO LUIGI
IPC: F16K21/16
Filed: 1967-11-04
Abstract: Means for discharging a predetermined volume of gas from the gas space of a liquefied gas, e.g. petroleum gas storage cylinder 3, Fig. 1, when a two-position discharge valve 21 is opened by moving an external lever 13 from its closed to open position shown in Fig. 3 comprises a float 40 which when the lever 13 is in the open position is latched to a rod 26 extending through the float and having its upper square end 25, Fig. 4, in sliding engagement with a squaresectioned chamber 24 formed in the lower end of the valve 21 and carrying an abutment 36 which when the float 40 sinks a certain distance, irrespective of the liquid level, releases a valveholding pin 30 thereby allowing the valve 21 to be closed by a spring 19 even though the lever 13 remains in the open position. The lever 13 is fixed to an arbor 12 which projects through a fixed member 14 and has a square end 16 slidable in a recess in the upwardly spring-biased head 17 of a shank 20 integral with valve 21. The upper end of the head 17 has diametrically opposed cam lugs 18, 181, Fig. 5, which when the lever, arbor and head are rotated ride over lugs 15, 151 on fixed member 14 resulting in opening of valve 21 to a position in which a notch 37 is engaged by the pin 30. The rotational movement of the valve when being opened is transmitted to the rod 26, which after a 90 degrees turn is latched to the float by engagement of diametrical longitudinal extending ribs thereon with spring clips on the float and the rod is thus moved downwardly by the float as the liquefied gas vaporizes until the abutment 36 strikes a lever 33 to withdraw the pin 30 and allow valve 21 to be closed by its spring 19. To effect a further discharge of gas lever 13 is moved from its open to its closed position resulting in rod 26 being rotated 90 degrees and unlatched from the float 40 and returned by its spring 49 so that its square end 25 is near the upper end of chamber 24 in valve 21 and the lever 13 is then turned to the valveopen position. In a modification the upper square end of the rod 26, Fig. 8, is in direct sliding engagement with the arbor 53, and the two-position valve 55 is unseated by an arm 56a of a three-armed lever 56 having an arm 56c engaging a cam slot 51 in an extension 52 of the arbor 53. The third arm 56b when engaged by the abutment 36 on rod 26 in its lower position rotates lever 56 to close the valve 55. As in the previous embodiment rod 26 becomes latched to the float when the manual lever 54 is turned from the valve-closed to valve-open position and the rod remains latched until the lever is returned to the valve-closed position.

Title: Rectifier device with silicon semiconductor rectifying elements disposed respectively in disc-shaped housings abutting stackable cooling members
IPC: H01L25/03
Filed: 1968-10-26
Abstract: A rectifier assembly comprises two or more parallel stacks of rectifier elements clamped between yoke members, the elements at one end of each stack being electrically interconnected and electrical lead-in and out conductors being disposed to one side of the stacks and connected thereto by resilient members. Fluid coolant is passed through hollow cooling elements which form part of the stack and are thus pressed into heat conducting contact with respective rectifier elements. In the arrangement shown in which only one stack is fully visible the elements, encapsulated in disc shaped housings are connected to form a 3-phase bridge. The D.C. output conductors P, N and A.C. inputs R, S and T (not visible) include flexible links 39 and the stacks may be suspended from them. Their ends are clamped between hollow cylindrical cooling elements 9, 10, 11 and may form cover-plates therefor. Coolant is supplied to the cooling elements via inlet and outlet manifolds 36, 37 prefabricated from plastics material and the entire assembly sealed in a watertight casing 38 thereby preventing ice accumulation when the system is operated at sub-zero temperatures as when cooling is achieved by evaporation of low boiling point coolants in the hollow elements. The stacks are clamped between yokes 20, 21, one of which electrically connects the end elements of the stacks. Clamping pressure is provided by a central nut and bolt arrangement and is communicated to the stacks via balls disposed between them and the yoke 20. Where, as shown, the rectifier elements are thyristors the controlling pulse repeaters 40 are mounted against the stacks. An arrangement with vertical stacks is also envisaged.
