Inventor: HUNI HANS
IPC: C14B1/00
Filed: 1967-06-21
Abstract: 1,186,368. Tanning leather. H. HUNI. June 21, 1967 [July 11, 1966] , No.28629/67. Heading C6C. A tanning plant comprises a rotatably driven horizontal drum with means for discharging tanning solution through a hollow axle journal which is connected to a controllable pressure source, said means being shielded from skins inside the drum by a perforated screen. A rotable horizontal tanning drum 1 has stub axles 2 and 3 journalled in supporting standards 4, at least stub axle 2 being tubular. An outlet opening 12, through which liquor can be discharged, is located in one end wall close to the peripheral wall of the drum. The opening 12 can be closed or opened by a sliding gate (not shown), which is connected to and actuated by a piston in a pneumatic cylinder 11, whose two ends, respectively, are connected by flexible hose pipes 8b and 9b to the inner ends of passages 7a and 7b through a non-rotatable coupling member 6 passing through the tubular stub axle 2. The outer end of the passages 7a and 7b, are connected through pipes 8a and 9a, respectively, and through a valve 13, to a pipe 14 supplying compressed air. The valve 13 may be operated automatically, e.g. magnetically, by a punched card device or a timeswitch, and may have a venting outlet 15. The outlet 12 and hose pipes 8b 9b are shielded from contact with skins in the drum by a perforated screen 16. In carrying out tanning, the opening 12 is closed by the gate, and skins and tanning liquor are fed into the drum, through an opening 5 in its peripheral wall, which opening 5 is then closed, and steady rotation of the drum commences. When the skins have been tanned sufficiently, rotation of the drum is stopped when the outlet opening 12 is substantially in the lowermost position, the valve 13 operates to open the gate, and tanning liquor is discharged through the opening 12, assisted, if desired, by the pressure of compressed air fed into the drum through stub axle 3.

Title: Improvements in or relating to master-slave manipulators
IPC: G21F7/06
Filed: 1964-07-13
Abstract: 1,009,637. Manipulators. H. WALISCH MILLER July 13, 1964 [Aug. 21, 1963], No. 28788/64. Addition to 987,299. Heading B4Q. In order to faciliate removal of the slave arm of the manipulator of the parent Specification locking means are provided which act automatically during the removal operation to prevent functioning of the various motions of the parts of the slave arm. If desired the master arm may be provided with similar locking means. As shown rotary shaft 2 represents one of a number of shafts extending in a through tube of the manipulator through the shielding wall of a hot cell, these shafts transmitting driving motion from the master arm (not shown) to the various operating shafts, such as shaft 6, of the slave arm situated in the hot cell. Each shaft 2 is connected to a shaft 6 through a disengageable plug-type coupling comprising lugs 12 co-operating with recesses in the end 10 of the shaft 6. Fig. 2 shows the shafts 2, 6 disengaged which is a preliminary stage in the removal of the slave arm. The slave arm comprises a cylindrical head 15 having pegs 22 supported by bearings 23 of a base 24. Normally, the base 24 lies against the end closure plate 27 of the manipulator through tube and guide pegs 44 lie within recesses in the head 15. Axial movement of the head 15 is performed by rotating an axially-restrained threaded spindle 30, this spindle co-operating with a threaded stud 25 integral with the base 24, the stud being guided by a sleeve 28. The spindle 30 may be rotated by a motor driving through gearing 38 and a shaft 34. As shown in Fig. 2 the slave arm may be removed by lifting the pegs 22 from the bearings 23. The locking means to prevent unwanted motion of each of the shafts 6 comprises a lever 20 pivoted at 17 in the head 15 and biased by a spring to take up its locking position shown in which its lower edge enters one of a number of grooves 13 on the shaft end 10. When the base 24 is against the plate 27 pins 43 on the plate 27 lift the levers 20 so that they leave the grooves 13.

Title: A device for setting a measuring mechanism according to a basic value having more than one digit
IPC: G01G23/22
Filed: 1951-12-10
Abstract: 709,962. Weighing-apparatus. KRAUT, sen., W., KRAUT, jun., W., and KRAUT, E., [trading as BIZERBA WAAGENFABRIK W. KRAUT KOMMANDIT-GES.]. Dec. 10, 1951 [Dec. 18, 1950], No. 28941/51. Class 143 [Also in Group XIX] A price-indicating weighing machine with a device for setting an indicator to a basic price of the weighed goods, the price having more than one digit, comprises a plurality of numeral setting elements which are adjusted independently of each other and which act on the same displacement member, though with different transmission ratios which correspond to the denomination of the digits set by the individual numeral setting elements. In one embodiment, Fig. 1, two numeralsetting elements comprise swivel arms 11, 12 pivotally mounted on shafts 13, 14 and secured respectively to toothed segments 15, 16, which mesh with the same toothed roller 17 which is longitudinally displaceable and rotatable on a cylindrical column 19 fixed to the base of the machine. The peripheral surface of the roller 17 is studded with teeth 171, disposed longitudinally, acting as a rack engagement with the sector 15, and teeth disposed circumferentially, engaging the sector 16 which can thus rotate the roller 17. The bottom of the roller 17 is mounted in a cup 20 which carries on a pin 23 a roller 22 for engagement with a screw-threaded grove 173 in the roller whose pitch is ten times that of the 171, and an arm 201 fixed to the cup 20 engages a post 21, preventing rotation of the cup 20 while allowing vertical movement. If a number is set by the arm 12 while the arm 11 is held, the cup 20 will rise one-tenth of. the distance it will rise if the same number is set by the arm 11 while the arm 12 is held, thus the cup 20 can be caused to move in accordance with any basic price represented by a two digit number and the cup 20 can be arranged to move a price indicating scale through transmitting mechanisms as required. In a weighing machine in which a plurality of scales. is scanned by an adjustable optical system, the system may be adjusted by means of the displaceable cup 20. In another embodiment two numeral setting discs 31, 32, Fig. 3, have setting levers 33, 34 and ratchet recesses 311, 321 in which engage spring-loaded pawls 35, 36. Displacement of the setting disc is converted to -linear displacement of an element 37 on a guide rod 38 through band and pulley means. An inelastic band 42 e.g. of steel, is attached to the disc 31 at 46, passes round pulleys 39, 40 and is attached to the element 37 while a 44, 45 and is attached to the discs 31 at 47. continuation band 43, 46 passes pulleys The pulleys 40, 45 are co-axial and fixed, the pulleys 39, 44 are carried bypivoted levers 50, 48 with springs 52, 49 to keep the band taut. A cam 53 on the axis of the disc 32 bears on the lever 50 and the ratios of transmissions are so chosen that the element 37 is displaced on turning the disc 32 only a tenth of the distance it is displaced on turning the disc 31 the same amount.

Title: Control system using a flow control valve
IPC: F01D17/22
Filed: 1973-06-19
Abstract: 1425528 Automatic control systems NISSAN MOTOR CO Ltd 19 June 1973 [21 June 1972] 29035/73 Heading G3R In a retroactive system for controlling a variable, e.g. speed or inlet temperature of a gas turbine, by adjusting a fluid-flow by means of a valve with a variable opening, pressure difference between the upstream and downstream sides of the valve is controlled in dependence on the commanded value for the variable. It is shown mathematically that this pressure control maintains the sensitivity of the system over all commanded values whereas without it the system is less sensitive for the higher commanded values, due to the characteristics of a variable opening valve. An error signal e electromagnetically controls the plunger 10c in the opening 10b of the valve in a proportional manner, while a spool 16 partially closes a drain opening 15 in a conduit 12 ... 14 shunting the valve; its position is determined by the command signal Xs acting in the same direction as a spring 18 against the pressure differential across the valve. The pressure differential is proportional to the square of the command signal.

Abstract: 1305236 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 16 June 1970 [30 June 1969] 29114/70 Heading H1K Electromigration in and environmental damage to conductive tracks of silver in integrated circuits is reduced by surrounding the tracks with a layer consisting of one or more refractory metals, such as nickel, chromium, tantalum, titanium, molybdenum and tungsten. Typically the tracks extend to platinum silicide contacts located in apertures in a silicon dioxide passivating layer on a silicon wafer. In one preferred embodiment layers of chromium, silver and chromium are vapour deposited overall to thicknesses of 700, 7000 and 500 Š respectively and then etched or back-sputtered using photoresist masking to form conductive tracks but with the lower chromium layer maintained intact. Nickel is then deposited by electroplating, the tracks protected by photoresist, and excess nickel and underlying chromium removed by etching or back-sputtering to leave nickel only on the edges of the silver tracks. In another embodiment, Fig. 6D, the wafer, carrying a Cr-Ag-Cr sandwich track produced as above, is coated by evaporation or sputtering with chromium to a thickness of 1000 Š and the chromium between tracks removed. In yet another case a silver coated chromium track is coated with 200 Š of nickel by electroplating overall followed by back etching of unwanted nickel. Finally in a simpler method the tracks are made by coevaporation of silver and chromium (1-5% by weight) at <200‹ C. followed by patterning. Heating, e.g. for from 10 sees. to 2 hours at 700-500‹ C. causes the chromium, which is in supersaturated solution, to diffuse to the surfaces of the track to form the protective layer.

Title: Improvements in marking metal articles
IPC: B44B5/00
Filed: 1936-10-28
Abstract: 483,503. Electrolytic printing-apparatus. CROSSE & BLACKWELL, Ltd., CLAYTON, W., and SUMNER, C. G. Oct. 28, 1936, No. 29242. [Class 41] Metal articles are treated over localized areas so as to form a pattern by applying thereto a unit comprising an electrode and means to carry a charge of electrolyte, the article constituting the second electrode. The electrolytic treatment may consist in etching, formation of an oxide film by anodic treatment or electrodeposition of metal; in each case it is carried only so far as to produce visible contrast without substantial formation of reliefs or recesses. The invention is particularly applicable to the coding of metal cans, whether empty or full, in rapid sequence ; the apparatus may form an attachment to a can seamer of the double rotary turret type. The marking apparatus may comprise an electrode in the form of a letter or pattern covered by porous material impregnated with the electrolyte ; the porous material may be in the form of an endless band which is passed through a vessel containing electrolyte between successive operations. Alternatively the covering material may comprise porous parts in the form of a pattern separated by non-porous parts or it may consist of porous material partially covered by non-porous material. Another form of apparatus comprises an insulating body with recesses in the form of a pattern to receive a pasty electrolyte, the electrode members being mounted within the recesses. Another apparatus comprises a hollow electrode having an insulated and perforated base through which a pasty electrolyte is forced by a plunger when the apparatus is brought over the work. The apparatus shown comprises an electrolyte container 1 having an insulated base provided with perforations normally obturated by insulating members 4 on a plunger 3 carried by the electrode 2. On engagement of the apparatus with the work the members 4 are raised and allow electrolyte to pass through, the rate of flow being controlled by a valve 5. In a modification the obturating members do not pass through the apertures, the plunger being actuated by external means. For anodic oxidation of tin the electrolyte may consist of sodium carbonate, hydroxide or citrate, ammonium carbonate, Rochelle salt, disodium hydrogen phosphate, potassium dihydrogen phosphate or an equimolecular mixture of the last two, in concentrations of 1 per cent or more. For anodic etching a 5-10 per cent solution of sodium or ammonium chloride or ammonium nitrate is employed. Tartaric or citric acids or their alkali metal salts are preferably added to redissolve precipitated tin compounds. For electrodeposition of copper a bath containing 0À2-0À3 per cent of CuSO4.5H2O in alkaline tartrate or citrate solutions is employed.
