Filed: 1922-10-05
Abstract: 209,191. Soc. Anon. des Anciens Etablissements Hotchkiss et Cie, and Taylor, H. E. Oct. 5, 1922. Shaping; tools.-Cam shafts, e.g. for internal-combustion engines, are machined by a series of planing-tools which are controlled by a master cam shaft rotating in phase with the work, the cutting action of the tools being in a direction parallel with the work axis. The work E, Fig. 1, is mounted by means of a chuck L and a swivel bearing L' in a vertical slide J which is reciprocated by a crank-shaft driven through gearing from the main shaft of the machine. The planing-tools C<2>, one for each cam, are carried by holders formed with slots in which operates the cams D<2> of the master cam shaft D. The holders are held up to their operating cams either by springs or by a system of interacting levers Q, Q<3>, Q<4>, acted on by a cranked lever and a hanging weight. The master carn shaft and the work are rotated synchronously by worm gearing M, O<2>, splined shafts being provided as necessary. The master cam shaft is carried in eccentric bearings P, P<2> which are yoked together and are partially rotated at each reciprocation of the elide J in order to lift the tools clear of the work during the idle stroke. The depth of cut is determined by a cam F actuating a rod G' having a threaded portion G<4> connected by means of a nut G<5> to the slide B on which the master cam shaft and the cutting tools are mounted. The nut G<5> may be rotated by a handle to adjust the slide B independently of the feed cam F. The master cams are made larger than the work shaft cams but have the same lift and angular pattern. The machine is started bv a handle S and a handle T may be provided to throw the feed cam in or out of gear. The machine may be stopped by an automatic mechanism operated by the feed cam. In a modification, the tools may be secured in levers which are rocked by the cams of the master cam shaft.

Title: Improvements in or relating to delivery apparatus for use with printing, cutting andsimilar machines
IPC: B65H31/30
Filed: 1931-09-28
Abstract: 380,610. Sheet-delivery apparatus. KNIGHT, J. B., BINGHAM, A., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Sept. 28, 1931, No. 26955. [Class 100 (i).] In delivery apparatus for use with printing, cutting, and similar machines wherein the stack of sheets moves vertically upwards, means are provided for separating the batches of sheets from the vertically moving stack, comprising guide members arranged to move in and cut off a batch containing the desired number of sheets from the top of the stack and lift them clear thereof, and a pusher-device which carries the separated batch out of the line of the moving stack. The arrangement is shown as applied to a stacking apparatus of the kind described in Specification 252,278, [Class 100 (i), Feeding and delivering webs &c.], wherein the sheets from a printing machine are conveyed by belts 1 and delivered to a group of four screws 2 and conveyed to the top of the screws into a pile. Guides 3 of angle-iron at the sides of the stacker are caused to move beneath a batch of sheets and lift it clear from the rest when a chain-conveyer 4, carrying a pusherpiece 5, then moves the batch of sheets laterally out of the stacker and on to a pair of angleguides 6 which form a continuation of the guides 3 when the latter are in the upper position. The pusher-piece 5 is guided by a fixed guide and tripped towards the end of its movement by a fixed plate so that its edge rises almost vertically at this point and does not disturb the arrangement of the sheets in the batch. The guides 3 move outwards from the stacker as soon as the batch of sheets has been carried away by the pusher-piece 5 and return again to their lower position ready for insertion beneath the next batch. The apparatus is operated at predetermined intervals by a cam 9, driven from the printing machine, which moves a lever 10 pivoted at 11, which in turn rotates the spindle 12 and causes the bar 13 carrying one angle-guide 3 to move upwards against the action of a spring 14. The guide 3 at the other side of the machine is operated from the same cam 9 through a link 15 and bar 13<1>. The bar 13 is pivoted at its lower end to a lever 13a secured to the spindle 12 and its upper portion, provided with a camfollower 18, works in a slot 16 in a bracket attached to the frame. The slot 16 is provided with a cam track with a central guide. The bar 13 is caused to oscillate about its pivot by a spring 20 so that the upper end of the bar moves up one side of the cam-track and returns down the other side. The bar 13<1> is actuated in a similar manner. The upper end of the screws 2 are carried in a bearing-plate in order to prevent any obstruction to the movement of the sheets.

Title: Optical instrument focusing mechanism
Inventor: MUELLER ARTHUR CARL
IPC: G03B13/20
Filed: 1969-05-28
Abstract: 1,209,860. Camera focusing mechanism. BELL & HOWELL CO. May 28, 1969 [June 7, 1968], No.27021/69. Heading G2A. In a camera which is sighted at the foot of a subject to be photographed, and the angle with the optical axis taken up by a freely swinging pendulous member 61 determines the focus, the focus adjustment is effected by a drive from an electric motor 28. Power is transmitted from the motor to the lens assembly 23 via a system of gears, a worm-wheel 42 mounted loosely on a shaft 43 being urged by a spring 47 into contact with a face gear 44. Face gear 44 is thus driven as a friction clutch by wheel 42, and engages with a gear ring 32 having a hub portion 33 secured within a rear extension 20 of the lens mount 21. Thus lens mount 21 and lens 22 are given an axial focusing movement. The pendulous member 61, of conductive material, is pivotally attached by a screw 64 to a disc-like carrier plate 54, which itself pivots on a bearing about a rod 53. Plate 54 has a peripheral gear sector 56 which meshes with a pinion 51 mounted on shaft 43 forming part of the gear train between motor and lens mount. Mounted on plate 54, on each side of member 61, are contacts 66, 67 forming part of an electrical circuit connecting motor 28 to a set of batteries forming a power supply, and which includes a manual switch (82,) Fig.4 (not shown). When the camera is inclined to its "sighting" position Fig. 5 (not shown), the swinging movement of member 61 is curtailed by engagement with contact 67, so that plate 54 is also rotated. On now closing the switch (82), a circuit is completed through the motor which drives plate 54 anti-clockwise sufficiently for member 61 to swing free under gravity, and assume a vertical position, in which its orientation to the optical axis is a measure of the focal distance. Simultaneously, the motor drives, through the gear train, the objective lens 22 in an axial movement to adjust the focus. The switch (82) is now opened, and the camera restored to a normal attitude for taking a photograph (i.e. with the optical axis horizontal).

Title: Furnace for the manufacture of fissile and/or fertile nuclear fuel carbides
Inventor: BEUCHERIE PIERRE
IPC: C01B31/30
Filed: 1964-07-03
Abstract: A nuclear fuel carbide is obtained by heating a mixture of a halide of the metal with a reducing metal, e.g. Mg, and carbon. In a preferred form uranium chloride is used and is obtained by chlorinating spent irradiated uranium carbide fuel.  Two processes are described:  (a) The spent fuel is added to a molten NaCl-KCl bath maintained at 700 DEG  C., and HCl or Cl2 introduced. UCl4 and/or UCl3, together with fission product chlorides (viz. rare earth, alkaline earth, and alkali metals) are formed and dissolve in the bath, while volatile metal chlorides, e.g. ZrCl4, MoCl3 and NoCl5 escape.  The bath is then filtered through porous graphite at 800 DEG C.  Mg and graphite are added as pellets containing the required stoichiometric proportions, and the mixture is heated.  Precipitated uranium carbide is removed by filtration through porous graphite. (b) The spent fuel is treated in a fluidized bed fed with HCl and then with Cl2 and argon. Solid UCl3 and/or UCl4 and fission product chlorides are carried with the volatile products and separated from them in a cyclone.  The mixture of powdered chlorides is mixed with powdered or pelleted Mg and graphite, and heated in a furnace under vacuum or in argon at 700 DEG  C. and then at 1200 DEG  C.  MgCl2 and fission product chlorides first evaporate and are deposited on the cooled walls of the furnace, and uranium carbide powder is formed on the hearth.  In both processes the carburization is effected in a high frequency induction furnace having a water-cooled device for concentrating the field on the charge.  The uranium carbide produced may be purified by melting under vacuum by means of electronic bombardment or electric arc.
