Abstract: 1,118,848. Change speed control. PUBLICITE FRANCAISE. 30 Jan., 1967 [1 Feb., 1966], No. 4394/67. Heading F2D. A floor-mounted gear-shift control in an automobile having a' transverse engine and gear-box, comprises a shift lever 1 ballpivoted at 3 on a floor-carried support 4, and a block 5 engaged by the end 3a of the shift lever and so connected to cross-shift and gear-establishing levers f, h of the gear-box that rotation and axial movement of the block about and along a fixed longitudinal axis Z-Z respectively effects crossshift and gear-establishment. The cross-shift lever f is fixed to a shaft 15 and acts to translate the gear-establishing lever h which is slidably keyed on a shaft g. As shown, the block 5 is slidable but non-rotatable with respact to a rotatable tube 6, the block and tube having complementary surfaces 6, 7, and is fast with a shaft 16 journalled and slidable in the tube 6. Rotation of the block 5 and tube 6 by transverse shift lever movement F rotates the cross-shift lever f through an arm 11 carried by the tube, a pin-and-slot connection 12, 13, and an arm 14 fast on the shaft 15. Axial movement of the block 5 by longitudinal shift lever movement G rotates the gearestablishing lever h through the shaft 16, collars 18 on the shaft 16, a forked lever 19, 20, 22, a link 23, and an arm 24 keyed on the shaft g. A 1-4 and R change-speed grid diagram is marked on the support 4. In Fig. 2 (not shown), the pin-and-slot connection 12, 13 is replaced by a transverse connecting link (12a), and one or two elastically yieldable bias means acting on the block 5 or any other movable cross-shift means are provided to produce a return to the III-IV shift plane and/or a stiffness in cross-shift to Reverse. Such bias means may comprise one or two springs (26a) connected to act on the arm 11, or one or two screw-adjustable, spring-loaded plungers (25) supported in the wall of the support 4 and acting on the sides of the block 5. In Fig. 4 (not shown), the hollow tube 6 is dispensed with, and the arm 11 is fast on the shaft 16 and connected to the arm 14 by the connecting link (12a) of Fig. 2 (not shown), the connecting link (12a) accommodating axial movement of the shaft 16 during gear-establishment.

Title: Improvements in or relating to time-checking apparatus
IPC: G07C1/32
Filed: 1950-04-11
Abstract: 737,902. Time - checking apparatus. McLEAN, H. July 11, 1951 [April 11, 1950], No. 4411/53. Divided out of 737,867. Class 106 (4). The case 10 of a time-checking apparatus is provided with a portion 11 which can be .opened and which is held in a closed position by means of a lock 16, a cover-plate 27 being provided which automatically covers the keyhole of the lock when the key is withdrawn therefrom and which cannot thereafter be moved to allow access to the key-hole without causing a visual indication of such movement to be given and maintained until the apparatus is to be reset for a further time-checking operation. The invention is shown applied to apparatus of the type described in Specification 737,867 and the indication is given by the tearing of a paper seal 30 mounted on an apertured platform 40 formed on the underside of the lid 11 under its window 31 and the paper is torn by an upturned, sharpened portion 35 of an arm 33 pivoted at 34 to a hinged plate 32 urged by a helical spring 44 against the seal 30 to hold it in place. A spring 37 normally urges the arm 33 to hold the point 35 at one end of an arcuate slot in the hinged plate 32 but when the lid 11 is locked and the coverplate 27 is displaced to insert the key, a spring- loaded pin 39 at the end of the cover-plate 27 displaces the arm 33 causing the point 35 to tear the paper seal 30. Specification 655,139 also is referred to.

Title: Improvements in rolling mills
Inventor: NEUMANN KARL
IPC: B21B31/04
Filed: 1965-02-02
Abstract: 1,093,631. Rolling. MOELLER & NEUMANN G.m.b.H. Feb. 2, 1965, No. 4460/65. Heading B3M. A rolling mill includes rolls, supported between upper and lower frame parts 21 and 22, which are prestressed together by tie rods 23, an externally threaded sleeve 61 and mating ring 30 for each tie rod serving as an adjustable spacer between the frame parts. Fluid pressure when introduced into a spacer 52 stretches the tie rods to enable the spacer length to be adjusted, while further spacers 69 permit the rods to be expanded independently of the above system to provide roll gap control during rolling. The prestressing force in each rod is transmitted from a nut 24 on top of the rod, through an abutting sleeve 50, an internally threaded nut 64, a chain driven wheel 27, the frame part 21, ring 30, sleeve 61, a piston and cylinder 67, and the lower frame part 22. For changing the prestressing force, the tie rod is stretched hydraulically, the spacer adjusted in length, and the tie rod released again. To adjust the spacer, the wheel 27 is rotated to turn the ring 30 relative to the sleeve 45 by means of a driving sleeve 27a splined to the ring 30. Stretching the rod is achieved by introducing pressure fluid into the space 52 between a cylinder 59 abutting the sleeve 61, and a piston 60 abutting an internally threaded sleeve 63 which is screwed to the head 23b of the rod and also to the stem of the nut 24. A further piston 68 and cylinder 67 is positioned between the sleeve 61 and lower stand part, to allow for roll gap control. The arrangement for stretching the tie rods can be used for releasing jammed rolls if required.

Patent GB-366734-A (GB)
Title: Improvements in or relating to automatically operated dividing apparatus
IPC: B23Q16/06
Filed: 1931-02-13
Abstract: 366,734. Indexing. JUNGE, C., 28, Kaiserallee, and WERNER AKT.-GES., F., both in Marienfelde, Berlin. Feb. 13, 1931, No. 4593. [Class 83 (iii).] In automatic indexing mechanism wherein fluid pressure is used for operating the locking means and the indexing means for the index plate, two hydraulic control valves are provided, one of which is actuated by a part of the machine, e.g. the reciprocating table of a milling or grinding machine, to release the lock through a hydraulic piston whilst the other is actuated mechanically by the lock to effect hydraulically, first the indexing of the plate and secondly the return of the first valve to its initial position. More than one index plate may be operated simultaneously and as applied to two, the plates 3, 4 are secured to shafts 1, 2, and are rotated by change gears 5, 6, 8, the latter being actuated through a ratchet by a pinion 15 and a rack 13 connected to a hydraulic piston 18. The pivoted locks 28, 27 are moved into locking position by inclined surfaces 22, 23 on hydraulic pistons 10, 11 through levers 24, 25 and links 26, 29 and are released by the flat ends of the piston-rods engaging arms 30, 31 on the levers. The control valves 9, 12 are connected to the hydraulic supply 14 through pipes 17, 19 respectively, to exhaust through outlets 45, 36, and to the pistons 10, 11, 18 through pipes 32, 33. The pistons 10, 11, 18 may be returned by fluid supplied through the control valves 9, 12, but as shown are returned by a constant fluid supply to their smaller areas. In operation, with the index plates locked as shown, the machine table advances to cause an inclined dog 43 thereon to move the valve 9 to the left and admit fluid to the pistons 10, 11, thereby rocking the levers 24, 25 and releasing the locks 28, 27. An arm 16 on the lock 27 is connected to the valve 12 and consequently moves this valve to the left as the index plates are unlocked, thereby admitting fluid to the piston 18 and causing the plates to be indexed. At the end of its stroke, the piston 18 allows fluid to pass, by a pipe 37, to the back of the valve 9 and thus restores this valve to the initial position shown, causing the pistons 10, 11 to be returned and the locks to be restored by the inclined surfaces 22, 23. Rocking of the lock 27 causes the arm 16 thereon to restore the valve 12 to the initial position shown. The part 121 of the valve 12 is cut away at the top, as shown, so that in the right-hand position shown the piston 18 will be connected to exhaust whilst the pipe 39 will be closed by the lower part when in the left-hand position. The inclined surfaces of the locks 27, 28 give a final fine adjustment to the index plates as they enter the notches therein.

Title: Improvements in or relating to hydraulic actuators
IPC: F04B53/00
Filed: 1962-02-07
Abstract: 1,040,331. Reciprocating pumps. J. F. A. MEYER. March 28, 1963 [Feb. 7, 1962], No. 4633/62. Headings F1A, F1N and F1P. A pump, compressor or singlestroke motor diaphragm or piston is moved by the vapour pressure produced by passing an electric current through a liquid, e.g. water, in a chamber. In the embodiment of Fig. 1, diaphragm 2 is moved against a spring 29 by vapour pressure generated in chambers 7, 8, 9 and 10 acting through liquid contained in the system. The stroke is varied by selectively operating the chambers, vapour from chambers 8, 9 and 10 passing into chambers 5 and 6. The volumes of chambers 5, 6 and 7 are in the ratio 8:2:1 to give a stroke range of 10 steps. The electrode tips may be shaped such that when the liquid level falls to partially uncover them, the current flow is reduced to a level sufficient to maintain the volume of vapour constant, a time switch acting to cut off the current prior to the return stroke. During the return stroke under spring 29, the vapour condenses, cooling fins 18 being provided. In another embodiment a cooling jacket surrounds the vapour chamber and is filled with liquid, e.g. oil, during the return stroke and emptied during the working stroke. The electrode may be mounted on a bimetallic strip to compensate for pressure fluctuations. Compensation for liquid losses from the system or for variation in volume with temperature, is effected by a bellows either manually or automatically, e.g. by a sight-glass and set-screw, or a photo cell and cam. More than one electrode may be provided in the vaporizing chamber. Alternative shapes and arrangements of electrodes are described.

Title: Improvements in and relating to kinematograph apparatus
IPC: G03B15/08
Filed: 1935-02-13
Abstract: 440,529. Kinematograph apparatus. BLONDIN, M. C., 19, Rue Banes, Meudon, Seine, France. Feb. 13, 1935, No. 4634. Convention date, Feb. 14, 1934. [Class 97 (i)] Relates to apparatus for the direct observation of pictures arranged in parallel series a-h, Fig. 1, on a strip M, and consists in the provision of means for frictionally advancing the strip stepby-step, while a single mirror rotates step - bystep about an axis parallel to the series of pictures so as to bring the individual pictures in succession into the field of vision, the order of viewing being a<1>-h<1>, a<2>-h<2>, &c. One form of the apparatus is shown in Fig. 6, in which the guide 1 for the strip is of cylindrical form and the mirror 5 is mounted on the axis thereof. In a modification, the axis of the mirror is outside the axis of the cylindrical guide, and a stationary inclined mirror is disposed so as to make this axis and the axis of the guide images of one another in this mirror. In another modification, the guide may be flat and the rotating mirror used in conjunction with a series of small stationary mirrors disposed tangentially to a parabola of which the axis of the rotating mirror is the focus. The step-by-step rotary movement of the mirror 5 is derived from a stepped cam on the main shaft 18, preferably through gearing which permits the regulation of the movements of the mirror. The longitudinal step-by-step movement of the strip in the guide is produced by a friction roller, acting preferably in conjunction with a presser roller, and driven intermittently through ratchet gearing from a cam on the shaft 18. Means are also provided for regulating the amount of this movement ; and the series of pictures on the strip are spaced by one or more tracks with which the friction roller contacts. The shutter or shutters 171, 17<2> are driven from the shaft 18 by the worm 96, flexible shaft 95 and worm 94. Adjustment of the timing of the shutter is obtained by mounting the shaft of the worm 94 in a sleeve 99 which is threaded into a fixed part of the apparatus and has a turning lever 100. The objective lenses 61, where stereoscopic or binocular vision is desired, are mounted on a right and left handed screw-threaded shaft. The eyepieces 101<1> are similarly adjusted by a shaft 103, and secured in their adjusted position by clamps 104<1>. The apparatus is enclosed in a casing 22 with apertures 23 in the sides for the entrance and exit of the strips, and to facilitate entry of the strip, one side of the guide may have a hinged part at its leading end which is swung outwards by the operator through the medium of a press-button and flexible transmission rod. For stereoscopic effects the picture areas in the series have each a right and a left-hand picture.
