Abstract: 877,813. Microscopes; fine and coarse adjustments. COOKE, TROUGHTON & SIMMS Ltd. Dec. 18, 1959 [Jan. 1, 1959], No. 77/59. Class 97(1) [Also in Group XXIV] Gearing for use in microscopes or the like comprises fine adjustment knobs 31, 32, Fig. 3, fast upon a shaft 33 having a threaded enlargement 34 screwed into a sleeve 36 held stationary by friction engagement with a housing 12, rotation of the knobs screwing the shaft, &c. along and acting through a thrust bearing 54 to slide a two-armed spider 49, 50 along axial slots 52 in the sleeve, a worm 45 secured to the spider acting as a rack to produce slow rotation of a worm wheel 24 in mesh therewith. By alternatively turning coarse adjustment knobs 37, 39 secured on the sleeve 36, the friction drag holding the latter stationary is overcome, and the worm 45 is directly turned for a relatively fast rotation of the worm wheel 24. The friction drag opposing rotation of the sleeve 36 is obtained from annular washers 43, secured in journals 41 fast with the housing 12 and engaged by axially extending flanges on the coarse control knobs 37, 39. The worm wheel 24, Figs. 1, 2, is loose on a shaft 20 and lies between friction washers 25, 26 and hubs 27, 28 biased to engage therewith by a spring 29. If the motion of the shaft 20 is arrested while either the coarse or fine adjustment knobs 31, 32, 37, 39 are rotated, the worm wheel 24 continues to turn and slips relatively to the friction washers 25, 26. In the form shown, the shaft 20, which is journalled between bearings 21, 22 in the frame 1 of a microscope, is integral with a pinion 19 meshing a rack 17 on a support 8 vertically movable between rectilinear motion ball-bearings 9, 10 and carrying a stage 5 upon which may be placed a specimen for observation through the microscope objective 2.

Abstract: 1,185,135. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 2 Jan., 1969 [31 Jan., 1968], No. 190/69. Heading G6C. A fuel assembly adapted to be vertically positioned between adjacent fuel assemblies or other structural parts (such as moderator bricks) of identical shape to constitute a reactor core, and to be inserted/withdrawn by vertical displacement, has a central portion A of polygonal cross-section and two end portions B, C of relatively short length, the lower end portion B having a smaller cross-section than the central portion A and being provided with lugs 32 which each terminate in a bevelled tip and which lie on the lines of extension of the edges of the polygonal cross-section, and the upper end portion C being provided on each lateral face with a V-shaped ramp for abutment with the bevelled tips of adjacent fuel assemblies or other structural parts and guiding the lugs 32 of these fuel assemblies or other structural parts towards the edges of the polygonal cross-section. The central portion A comprises a casing 10 occupied by fuel pin bundles (not shown). The bottom portion B comprises an end connector 12 pierced by a central coolant duct and welded at 16 to the casing 10. A cylindrical extension 24 at the lower end of the connector 12 is intended to engage in a support grid (shown in chain-dotted lines in Fig. 1). Each lug 32 has a longitudinal ridge which forms an extension of the corresponding ridge of the casing 10. The lower end of each lug 32 has two bevelled facets, the ridge 36 between them being preferably rounded and inclined to the axis of the fuel assembly in a direction such that a thrust exerted on the ridge tends to centre the fuel assembly. The top portion C comprises an end connector 18 pierced by a central coolant duct 20 and welded at 22 to the casing 10. An annular groove 26 in the duct 20 is intended to accommodate the claws of a grappling device (shown in chain-dotted lines in Fig. 2). A ramp formed by two facets 38 and having the shape of an inverted V is provided at the extremity of each face of the end connector 18. In order to prevent two lugs 32 from coming into contact with two ramps at the same time and thus jamming the inserted fuel assembly, the ridges 36 of the lugs 32 are at different levels. When the fuel assembly is lowered into position, the ridge 36 of one of the lugs 32 comes into contact with a facet 38 on an adjacent fuel assembly or other structural part and as it slides over the facet 38, the inserted fuel assembly is caused to rotate. Each lug 32 is in turn brought into contact with a ramp and the rotation continued until the ridges 36 are in line with the edges of adjacent fuel assemblies or other structural parts.

Title: Improvements relating to the recovery of by-products of the manufacture of charcoal from wood and the like
Filed: 1943-01-05
Abstract: <PICT:0563906/IV/1> By-products of the manufacture of charcoal from wood, peat, lignite and the like are recovered by using cooled circulating pyroligneous acid to wash down and condense the tar and pyroligneous acid content of the hot vapours distilled from the wood, spraying the resulting hot acid into an air stream to heat the air and saturate it with acetic acid and water vapours, recirculating the unevaporated cooled portion of the spray acid, and recovering the acetic acid vapour from the hot saturated air by reaction with an alkali to form an acetate.  The vapours at a temperature of about 250-350 DEG  C. are discharged from the carbonizing plant, such as that described in Specifications 563,460, [Group XII], and 563,461, [Group XIII], by a pipe 1 into a cooler scrubber 2 having a baffle 3 forming a duct 4 for descending gases which then pass upwards through fillers 5. Cooling sprays 6-8 are fed with pyroligneous acid, produced as below and at a temperature of, say, 40 DEG  C., in amount sufficient to lower the temperature of the gases at outlet 9 to about 50 DEG  C. and of the condensed tar and acetic acid liquor to about 90-100 DEG  C.  The slight vacuum of the induction fan 11 results in the wood spirit remaining as vapour and being extracted with the gases and some water vapour.  After traversing a drop catcher 12, the gases, if desired after separating the wood spirit and water, are used as fuel for operating the plant or elsewhere.  The condensed liquor is run off by pipes 17-19 to a separating tank 22 having baffles 23-25 forming ducts for extracting tar at one end and pyroligneous acid at the other.  This hot acid is pumped through pipe 40 to the top of a packed cooling tower 27 down which it is sprayed against a current of cold air from fan 29 to give at the exit 30 air at, say, 60-80 DEG  C., saturated with acetic acid and water vapours. The unvaporized acid at about 40 DEG  C. is fed by pump 31 and pipe 32 to the sprays 6-8.  The acid-containing air is led by duct 41 to chamber 33 filled with or containing shelves of lime or other basic oxide, hydroxide or carbonate, whereby calcium or other acetate is produced, either in dry form or, if conditions are such that condensation of water vapour occurs, as a concentrated solution which is collected in tank 38.

Title: Improvements in electric clocks
IPC: G04C21/08
Filed: 1935-01-08
Abstract: 433,746. Clocks. JARRY, A. G., 17, Rue BrÚa, Paris. Jan. 8, 1935, No. 647. [Class 139] In a clock wherein an electric motor drives the hands directly or winds the mainspring, the rack of the striking mechanism actuates the hammer directly and is lifted by meshing with a normal wheel in the reduction gearing driven by the motor. The rack 5 is pivoted at P to a trip lever 6 pivoted at 7, and is normally held, as shown in Fig. 1, with its projection 14 on the top of an arcuate stop 15 by a spring 16 anchored at its lower end. The half-hour pin 2 on the control wheel 1 first rocks the trip lever 6 anticlockwise through arm 8 until the projection 14 slides over the stop 15 and the rack falls until the projection 14 engages the lower stop 17. At the half-hour, pin 2 releases arm 8 and the trip lever 6 rocks under gravity until held by the stop 6<1>, Fig. 3, the rack also being rocked until teeth formed thereon by pins 9 mesh with a wheel 10 in the motor drive and with the tail 11 of the hammer 12. The pitch of the pins 9 is a multiple of that of the teeth of wheel 10. One stroke is made as the rack is raised and as the projection 14 passes between the stop 15 and spring 16 it stresses the latter so that when the top of the stop 15 is reached the spring 16 rocks the rack out of mesh with wheel 10 to the position shown in Fig. 1. At the hour the hour-pin 3 rocks the arm 8 so that the projection 14 clears both stops 15, 17, and the rack falls until its arm 51 engages the hour snail 4, Fig. 4. When the pin 3 releases arm 8, the trip lever 6 rocks into engagement with the stop 6<1> bringing the rack into mesh with wheel 10 and the tail 11, striking being effected during return of the rack as above. When the electric motor 18, 19, Fig. 6, is used to wind the clock mainspring, overwinding is prevented by a brake 20, engaging the rotor 18, controlled by a conical travelling nut 21 actuated in known manner by the motor and also by the driven side of the mainspring. To ensure the motor running during striking an arm 24 rigid with the trip lever 6 is adapted to lift the brake arm 20 as the trip lever is rocked to bring the rack into mesh with its driving wheel. The arm 51 of the rack is provided, in known manner, with an elastic stop to prevent blocking of the snail should the current fail for a period including midday or midnight. For a large clock the motor may be controlled through a contact operated by means analogous to those for lifting lever 20 in Fig. 6.

Title: Process for utilising ferrous sulphate
IPC: C01G49/06
Filed: 1931-01-09
Abstract: In the reaction between ferrous sulphate and ammonia, producing ammonium sulphate and iron oxide or hydroxide, the latter is deposited by means of an oxidation process, oxygen or oxygen-containing gases being specified for this purpose, in a stage higher than the divalent stage of oxidation.  In examples, a solution of ferrous sulphate and ammonia is treated in an autoclave at 200 DEG C. with air at a pressure of 8 and 13 atmospheres respectively.  The process may be effected without pressure, but an elevated temperature is desirable.  In another modification, the admission of ammonia and the oxidation proceed simultaneously.  The filtered solution is concentrated.  The ferrous sulphate may be oxidized in the solid state, for example, by air at elevated temperatures (whereby basic ferric sulphate is produced); the product is reacted with aqueous ammonia and the ferric hydroxide filtered, or in a modification gaseous ammonia may be passed over the heated salt together with or subsequent to the oxidizing gases.  Above 400 DEG  C., ammonium sulphate is volatilized.  Reference is made to the use of directly-heated rotary furnaces.  Ferric oxide produced may be used as a polishing agent or pigment, or for the production of metallic iron.
