Patent GB-104564-A (GB)
Title: Improvements in or relating to the Art of Recovering Zinc from Zinc-bearing Ore, including the Manufacture of Briquets of Zinc-bearing Ore.
Inventor: JONES DAVID BENTON
IPC: C22B19/02
Filed: 1916-03-23
Abstract: 104,564. Jones, D. B. March 23, 1916. Briquetting processes; distilling zinc. - Zinc ores are mixed with coke, preferably in a finelydivided state, and a carbonaceous binding-material, and the mixture is briquetted. The quantity of coke used is more than sufficient to reduce the metallic oxides in the ore and is such that the weight of the briquette after distillation is not less than about 40-50 per cent of the weight before distillation. The quantity of pitch, tar, or other carbonaceous binder used is 10-15 per cent of the combined weight of the ore and coke, and the briquette maintains its form and volume during the process of distillation. The briquettes are dried and heated under non-oxidizing conditions, for example by embedding them in powdered coke to a temperature high enough to coke the binding- material, but not high enough to volatilize the zinc; the briquettes are then subjected to the usual distillation process for obtaining spelter or zinc oxide. During the drying and heating operation, the briquettes may be supported in cups of fire-clay &c. to prevent collapse; or if the briquettes are embedded in powdered coke, this will serve to support them.

Abstract: 1514531 Solenoid locks WILMOT-BREEDEN Ltd 26 Jan 1976 [4 Feb 1975] 4639/75 Heading E2A A door lock comprises a pawl-operating lever 15, movement of which operates a door latch, a release lever 16 connected to manually operable means, and a locking member 17 movable under the influence of doubleacting solenoid 12 between an unlocking position, in which it couples lever 15 to lever 16 so that movement of the latter operates the door latch, and a locking position in which no such coupling occurs. Levers 15 and 16 pivot about pin 14 provided on the mounting plate 10, the locking plate 17 is sandwiched between these plates and slides between the locking and unlocking positions by virtue of slot 17a over pin 14. In the unlocking position illustrated in Fig. 1, projection 17c on the locking plate 17 engages together with projection 15d on lever 15 in slot 16a in release lever 16. A similar projection on locking plate 17 engages in a slot (not shown) in lever 15, so that these two are permanently coupled. This couples levers 15 and 16 together so that clockwise rotation of lever 16 via handles attached to link 18 or lever 19 causes clockwise rotation of lever 15 and operation of the door latch via pawl-pin P. Operation of the solenoid 12 pushes rod 22 further out and moves locking member 17 so that projection 17c is no longer in engagement with slot 16a. Key-operated means may be coupled to the solenoid plunger via rod 23 so that the door may be opened in the event of electrical failure. The locking plate 17 may be coupled through eye 17e to a manual operating means.

Title: A device for measuring changes of distance between two relatively movable parts such as parts of machine tools
IPC: B23Q17/22
Filed: 1942-04-15
Abstract: 556,856. Gauging-devices &c. BENKOE, I. April 15, 1942, No. 4993. [Class 83 (iii)] Apparatus for measuring changes of distance between two parts consists of a gauge mounted on one part, and a stop on the other part, the stop being frictionally mounted in its support so that distances greater than the range of the gauge may be measured by readjusting the stop. In the application to a lathe the cross-slide 12 mounted on a saddle 11 moving on the bed 10 carries a bracket 19 which accommodates a transverse rod 18 frictionally held in the bracket by spring plungers 22. The rod 18 has a pivoted end 17A carrying a pin 17 engaging the feeler 14 of a gauge 13 on the saddle so that the cross slide movements are recorded on the gauge. The link 17A is slidable in a bore 26 in the gauge housing and carries bosses 28, 29. The gauge dial has a protecting cover 34 and is movable to any angular position. Before an operation the rod 17A is moved to the left so that boss 29 abuts the housing and the gauge set to zero with the tool touching the work. The work may then be turned down to the full extent recordable on the gauge and another reading taken. The rod 17A is then again pushed to the left to the Fig. 2 position, the friction plungers 22 yielding to permit this movement. This restores the gauge to zero and an additional measured cut may then be taken. If the feed is not stopped when the gauge reaches the limit of its scale, the boss 28 engages the housing and further movement of the cross slide then causes rod 13 to slip in its mounting, thus preventing damage to the gauge. A modified form is illustrated in the Provisional Specification.

Title: Process for obtaining diazo-sulphamic acids of the cyclic series
IPC: C07D291/08
Filed: 1927-02-22
Abstract: 266,388. I. G. Farbenindustrie Akt.- Ges. Feb. 22, 1926, [Convention date]. Diazosulphamic acids; azo dyes. - Diazosulphamic acids are made from cyclic diamines or polyamines by converting them into di- or polysulphamic acids and treating the latter with nitrous acid in the proportion corresponding with the amount required to diazotize one amino group. One sulpho group is thereby eliminated, and diazosulphamic acids are formed which may be used for the production of dyestuffs, e.g. by coupling them with #-naphthol, or for the production of other compounds by substitution of the diazo group by Sandmeyer's reaction. The sulpho groups may be readily split off from the dyestuffs, whereby azo dyestuffs which may be regarded as derived from partially diazotized diamines or polyamines are obtained. The amines are converted into sulphamic acids by heating them with halogen sulphonic acids or their esters in the presence of a tertiary base. In examples, the following amines are heated with chlorsulphonic acid and pyridine, to produce di- or poly-sulphamic acids which are converted into the diazo-sulphamic acids and coupled with #-naphthol to produce reddish or violet dyestuffs :-o- and p-phenylenediamine, m-toluylenediamine, benzidine, 1:5-, and 1 : 8-diaminonaphthalene. The Specification as open to inspection under Sect. 91 (3) (a) comprises additional examples in which dianisidine, 1 : 2-diaminonaphthalene, and 1 : 2 : 4-triaminobenzene are converted into the corresponding diazosulphamic acids and coupled with #-naphthol to produce dyestuffs. The following diamines may also be converted into disulphamic acids and diazosulphamic acids :-1 : 3- and 1 : 4-diaminonaphthalene, p-diaminoazobenzene. benzidine-o-dicarboxylic acid, and 3 : 6-diaminocarbazole. This subject-matter does not appear in the Specification as accepted.

Filed: 1959-02-13
Abstract: 866,849. Packaging powders. HESSER, MASCHINENFABRIK A.G., FR. Feb. 13, 1959 [March 17, 1958], No. 5070/59. Class 94(1). [Also in Group XXIV] A machine for packaging powdered material into packets P, Fig. 1, comprises a continuously rotating distributer plate 2 carrying a number of dispensing screws 8, means for moving the packages P through the machine so that each package remains below a screw 8, and means for controlling the rotation of the screws from the rotary motion of the plate 2. The packages P are carried into and through the machine by a conveyer belt 1. Clutch control. In Figs. 1 and 2 each dispensing screw 8 carries at its upper end a freely mounted pinion 17 that is in continuous mesh with a stationary toothed ring 18, the rotation of any pinion being effective only when an associated electric clutch 16 is energised. For this purpose pick-ups 20, 21 extend from each clutch 16 to slide against some busbars 22, 23. The busbars 22, 23 comprise overlapping sections, the setting of which is adjusted in accordance with the number of revolutions each screw must perform during its dispensing operation. Gearing for conveying intermittent motion. In Figs. 3 and 4 the number of revolutions of the dispensing screws per revolution of the distributer plate 2 is controlled by cams 30, 39. As the distributer plate 2 carrying the dispensing screws 8 rotates, rollers 32 on toothed discs 31 bear against the cam rail 30 and each disc 31 is thereby turned. This rotation is transmitted by teeth 34 to a pinion 35 geared through a free wheel device to a dispensing screw. A second cam rail 39 is used to turn the discs 31 back to their initial angular positions, the free wheel devices allowing this back rotation without a reverse turning motion being performed by the screws 8. To pre-set the revolutions of each dispensing screw, the cam rail 39 is turned about a pivot 40 and as a result the position for the start of a fresh dispensing operation by each toothed disc 31 is modified, whilst the end position of the disc is always left unchanged.
