Patent GB-627303-A (GB)
Title: Improvements relating to hand operated stackers and more especially to winch mechanism therefor
IPC: B66F9/02
Filed: 1946-07-31
Abstract: 627,303. Hand-operated stacking-machines. SLINGSBY, G., and SLINGSBY, C. July 31, 1946, No. 22781. [Classes 78 (iii) and 78 (v)] A winch for a hand operated stacker comprises a winding handle 23 coupled with a rotatable casing 28 containing a friction clutch and brake mechanism (e.g. 42, 35, 30) coaxial with a driving shaft 24 and driving pinion 25, and means (e.g. pawl 31) for preventing the casing from rotating in the unwinding direction, the arrangement being such that by rotation of the winding handle in one direction the winding handle is coupled to the driving shaft through the casing and the clutch, and when the winding handle is released the driving shaft is held stationary by the said means which prevent reverse rotation of the casing and the clutch, whilst when the winding handle is turned manually through a few degrees in the reverse direction the clutch is disengaged and the driving shaft is thereby allowed to be rotated in the unwinding direction by the load, braking being effected with the aid of the clutch by the winding handle being turned through a few degrees in the winding-up direction. In Fig. 4, rotation of the handle 23 moves threaded boss 34 inwards relative to the casing 28 so that disc 42, which is slidably keyed to shaft 24, is thereby pushed to the right and engages the shaped face of brake shoe 35. The latter is then held between movable disc 42 and fixed disc 43 and expands so as to lock together handle, casing, discs and shaft; thus disc 42 rotates with the handle and winds up the drum 18 through gearing 25, 20, 21, 22. When the handle is released the casing 28 is held by pawl 31 and the casing holds the shaft and handle through the brake which is maintained by spring 36 which couples the casing 28 to the threaded boss 34 and operates so as to continue to wind in the handle. When the handle is unwound several times and held against the spring the pressure on the disc is released and the brake shoe contracts to free the shaft which unwinds under the action of the load. If the handle is now momentarily released the spring will come into play and brake the descending load. Centrifugal governor 37, Fig. 6. The speed of unwind under " free load may also be limited by governor member 37 which is pivoted at 38 to plate 39, which plate is integral with disc 42 and carries stop 40. As the load descends, shaft 24 rotates and the plate rotates with it so that increase of speed causes member 37 to swing outwards and increases the gap between nose 37<SP>1</SP> of member 37 and stop 40 and thus exerts pressure upon brake shoe 35 and brakes the load. Fig. 2. The winch is applied to stacker 1 to raise platform 8 which runs on rollers 9 in channels 2. The platform may have rollers 11 and be pivoted at 12 and be limited in movement by stops 13, 14 or may comprise pivoted forks.

Patent GB-803336-A (GB)
Title: Telegraph printing apparatus
IPC: H04L17/22
Filed: 1956-07-27
Abstract: 803,336. Typewriters &c. YAMURA, T. July 27,1956 [Dec. 24, 1955; Dec. 24, 1955], No. 23253/56. Class 100(4). In a telegraph receiving apparatus for use with both English and Thai or like language wherein certain letters are printed on top of one another the letter spacing mechanism is operative or not depending on whether the letters printed require spacing. When a signal is received, code bars 5, Fig. 2, and selector vanes 1 having been set, shaft 13 turns cam 14 which allows spring 46 to pull arms 12 counterclockwise thus turning shaft 21. Type bar 36 is urged towards platen 30 by bar 47 and bail 15. For English letters requiring normal spacing the signal also moves bar 39 which pivots shift lever 33 causing bell crank 44 to be moved so that arm 45 prevents control bar 6 from pivoting about shaft 8. Platen 30 is shifted by members 34, 35, 31 so that the upper letter on type 37 strikes it. Counter-clockwise rotation of shaft 21 rotates bail 22 and, since lever 6 cannot move, link 18 will be lifted, freeing pawl 17 from ratchet wheel 23 which turns until stopped by pawl 20. Cam 14 now urges arm 12 and bail 22 clockwise. Bail 22 strikes pawl 20 which frees wheel 23 to turn until arrested by pawl 17. This rotation moves type basket 4 one space through worm 25, gears 26a, 26b and rack 27. When two combined Thai letters are required with no space between them the signal for the first letter positions platen 30 through push bars 40 or 41 and the same linkage as above, whilst arm 45 allows lever 6 to pivot moving link 18 out of the path of bail 22, thus pawl 17 cannot be disengaged by bail 22 and the spacing mechanism does not function. In a second embodiment, Fig. 3, the spacing mechanism is electromagnetically operated. Type lever 4a is moved by bail 20a on operating shaft 21a through 17a and pull bar 18a. Operating shaft 21a simultaneously releases ratchet wheel 25a through spacer bail 22a which moves clockwise and pushes spacer control crank 27a to the left to disengage pawl 23a as bail 22a moves back to its rest position pawl 24a is also disengaged. When ratchet 25a is released shaft 26a revolves to move the letter spacing rack 40a through 31a, 32a, 33a, 32b. The letter spacing mechanism does not function when magnet 16a is energized, the eircuit to which is completed by contacts 34a closed by certain of pull bars 18a moving backwards to cause typing stroke. When magnet 16a is energized spacer control crank 27a is moved out of the path of bail 22a by rod 38a and armature 37a, the spacer pawls are thus not released by bail 22a. By connecting point 35a to the appropriate one of points 10a-15a or 36a of the platen-operated switch, the spacing mechanism can be cancelled in any one position, two positions, or all three positions of the platen. Thus, by suitably arranging the positions of the types on the type bars and the wiring of the switch, letter spacing can be retained or cancelled as required.

Title: Method of joining metal parts by spot welding
IPC: B23K11/10
Filed: 1959-07-07
Abstract: 872,232. Welding by pressure; soldering. BROWN, BOVERI & CIE A.G. July 7, 1959 [July 23, 1958], No. 23291/59. Class 83 (4). In joining metal parts by spot-welding a mixture of a hard solder and finely-divided high melting point additives which have melting points above that of the hard solder and which are capable of alloying with the parts to be joined, is placed between the parts and a welding current is passed therethrough so that the hard solder melts and wets the surfaces of the parts before the welding temperature is reached and welding takes place. In spot-welding copper and 18/8 stainless steel parts a paste comprising a powdered hard solder (melting point about 700‹ C.) and powdered copper, nickel, manganese and silicon is applied between the parts and current is supplied to the welding electrodes to first melt the hard solder. The electrodes press the still solid higher melting point additives into the parts to form local resistance spots and current flow is continued to effect spot-welding. The higher melting point components may be alloys, metal salts or reducible metal oxides and the joining may take place in an inert gas or alternatively a. reducing agent may be included in the mixture. The mixture may be plated on one or both surfaces to be joined.

Filed: 1948-09-08
Abstract: The degradation action of light on nylon textile materials, e.g. yarn, is reduced by incorporating with said materials a small proportion not exceeding 1 per cent by weight of a compound containing cationic chromium.  Since chromic ions are not themselves readily absorbed by nylon, the textile materials are first treated at 50-100 DEG  C. with an acidified aqueous dichromate solution and then with an agent capable of reducing the dichromate to chromic salt, e.g. sodium thiosulphate, sodium hyposulphite, sodium hydrosulphite, the condensation product of sodium hydrosulphite with formaldehyde, or formaldehyde.  Sodium, potassium or ammonium dichromate is suitable and the solution should contain 0.01-0.5 per cent of dichromate based on the weight of textile materials, and should have a pH not less than 2.5.
