Abstract: 400,892. Self-closing valves. LAMPLOTA, H., 6, Ceskß-ul, Brno, Czecho- Slovakia. June 30, 1933, No. 18648. [Class 135.] In a rack and pinion actuated lift valve the upper spindle guide, in which are disposed the rack 7, Fig. 2, pinion 9, and loading spring 18, is carried by an arm 1 projecting from the valve casing 2, the arm being spaced, as shown, from the gland 15 so as to allow the latter to be raised for renewal of the packing 14 and to keep the operating parts free from contamination by the liquid. The valve can be locked in its open-position by a spring-pressed sliding bolt mounted in the operating hand wheel carried by the pinion shaft 9. The valve may be mechanically operated for delivering predetermined quantities of liquid by means of a motor-driven crank pin 27, Fig. 9, connected by a link 26 to an arm 25 rotatably mounted on the shaft 10. The link 26 has a hooked extension 24 which engages a notch 23 in the operating disc 11<1> as the crank disc 28 rotates and opens the valve ; after the crank pin 27 reaches its lowermost position it turns the hook 24 out of engagement with the notch 23 and allows the valve to close. The process will be repeated at the next revolution of the disc 28 and an equal quantity of liquid delivered.

Title: Improvements in the manufacture of optical glass
IPC: C03B19/09
Filed: 1921-07-15
Abstract: 188,721. Parsons, Sir C. A., Peddle, C. J., and Duncan, H. M. July 15, 1921. Production of metal.-A method of manufacturing optical glass consists in allowing the glass to cool in the pot until it is still viscous but able to retain its shape without support, and then separating the pot from the bulk of the glass, thus leaving an isolated mass of glass free from any connection with the pot. In one manner of carrying out the invention, an open pot or one with a removable top is used, and after allowing it to cool, it is removed from the furnace and placed in an iron jacket a under a press. A tube c of steel with a sharpened lower edge is forced down into the glass e in the pot so that it cuts through the glass and shears a disc of the pot bottom into a recess f in the jacket. The tube c is then lifted slightly and a horizontally-moving knife h, moved by a ram k, enters an opening m in the base of the jacket and shears off the bottom of the pot from the mass of glass. Thus a block of glass isolated from the pot is obtained which may be either removed quickly or may be preserved by filling the surrounding annular space with kaolin. In a modification, the bottom of the pot may be cut off by supporting it in a rotating chuck and pressing cutting-discs against it. The tube c may have its lower edge toothed and may be rotated to cut the glass, and a large circular screw may be used instead of the knife h. In another method of carrying out the invention, the glass is separated from the pot by means of intense heat quickly applied to the exterior of the pot when inverted so that the layer of glass next the pot is melted and the block of glass drops out. In a further method, the pot is broken or pulverised by chilling, hammering, squeezing, rolling, or by other means, and the pieces are then removed from the block of glass.

Title: Apparatus and method for hot-briquetting multiple metal pieces
IPC: F27B9/18
Filed: 1969-04-15
Abstract: 1,271,312. Rotary hearth furnaces. BERWIND CORP. 15 April, 1969 [15 April, 1968], No. 19180/69. Heading F4B. Oil-coated scrap metal material such as turnings or borings is fed in through openings 81 on to the hearth 76 of a rotary hearth furnace 70 where it is heated before being discharged, free of oil, through a centrally disposed outlet 82 from whence it is passed directly to a briquetting machine (18, Fig. 1). The oil serves as fuel for the furnace, and combustion air enters the furnace through openings 94. The material is moved over the surface of the hearth towards the outlet 82 by means of a stationary rake structure 84 having blades 86. The combustion gases leave through an outlet 95 which communicates with an afterburner (28, Fig. 1) serving to reduce or eliminate the presence of unburned oil vapour in the exhaust gases; the exhaust gases are then passed through a scrubber (26, Fig. 1) before being exhausted through a stack (32) into the atmosphere. In a modified embodiment (Fig. 4, not shown) the hearth (180) is frustoconically shaped, being inclined downwardly towards the central outlet (186). The furnace may also be used to treat other materials, such as ores which have a fuel associated therewith.

Title: Improvements in automatically operating photometers
Inventor: LOEBL HERBERT
IPC: G01N35/02
Filed: 1965-05-07
Abstract: 1,149,384. Photo-electric apparatus. JOYCE, LOEBL & CO. Ltd. May 2, 1966 [ May 7, 1965], No.19307/65. Heading G1A. The colour, density, concentration &c. of samples is measured by a photometer which examines the samples sequentially, means being provided for rendering the indicating or recording device, which displays the measurements, inoperative while one sample is replaced by another, and, for a time before the actual measurement is made, to allow the sample, if liquid, to settle into position. Liquid samples treated by reagents &c. as described in Specification 1, 149, 382 may be transferred in turn to the measuring cuvette 4 of the photometer by means of a pipette and pump mechanism Fig. 1 (not shown), described in detail in Specification 1, 149, 383. Alternatively, liquid samples contained in their own cuvettes may be passed on a moving belt or table, which is stopped for the period of test. Solid samples may also be evaluated, by transmitted or reflected light. In the embodiment described, the photometer is of the double-beam type, light transmitted through the sample 4 and through a filter 21 and graduated wedge filter 22, being allowed alternately to illuminate a photo-cell 25, by a rotary shutter 24. Any difference in the two intensities is detected by amplifier 26 and a motor 23 caused to move the wedge 22 to equalize the beams. Also controlled, through gearing 27, is the movement of a pen on the paper roll 7, and the setting of slider 29 on potentiometer 28, which feeds a print-out device 13. The latter can produce digital print-out with or without tape punching. Adjustable resistors 31 are used to set the upper and lower limits of the potentiometer. A plug-in printed circuit 35 can be inserted to alter the potentiometer characteristic in the case of a non- linear sample property, so that the record is linear. Alternatively, a non-linear wedge 22 is used. Calibration of the photometer is by an empty cuvette to set zero and standard solutions. The operation of the photometer is controlled by a timer 33. A first pulse over lead 36 starts the pumping and a first portion of the sample washes out the cuvette 4. The cuvette is then filled with the sample and when liquid has settled down, the paper 7 and the print-out device are started. The pen and paper are stationary while the sample is removed and the cuvette flushed with the next portion of sample, while the printout device is prepared for the next sample, by movement of its sheet 9. In an alternative photometer, a single beam path device is used, the sample being compared with a reference sample or the photometer output compared with a standard signal.

Title: Process for the production by electrolysis of thin superposed nickel sheets and for separating them one from another
IPC: C25D1/04
Filed: 1927-07-22
Abstract: 275,221. Breuning, E., and Schneider, 0. July 27, 1926, [Convention date]. Preparing surfaces; treatment after electrolysis. -A composite sheet consisting of thin, easily separable layers of nickel, cobalt, iron or other metal is produced by electro-deposition, the surface being rendered passive after deposition of each layer. The layers are then separated by treatment in a weak acid which only attacks the metal slowly such as a 1-10 per cent solution of sulphuric acid, the action being due to generation of hydrogen between the layers. Passivity may be produced by treating the previously rinsed surface in concentrated nitric acid or chromic acid solution, or by electrolytic treatment in a 5 per cent solution of sodium hydroxide.

[Also in Group XVII] An adhesive bandage package comprises an adhesive bandage presenting an adhesive surface and a wrapper, part of which serves as a facing in contact with the adhesive surface, the wrapper comprising a pair of sheets connected by a breakable juncture, one of the sheets being removably wrapped around one end of the bandage to form a tab by which the bandage may be withdrawn from the other sheet. An adhesive bandage 10, comprising a tape 12 carrying pressure-sensitive adhesive 13 on one side and with or without a centrally located dressing pad 14, has one wrapper portion 21 around one end forming a tab 22 and a second wrapper portion 20 which extends along the remainder of the front and back of the bandage and is secured by heat-sealing or adhesive to the first wrapper portion 21 by a seam 35 at the back of the bandage. At the front of the bandage, the second wrapper portion overlaps the first wrapper portion and extends beyond the end of the bandage or is folded back on itself (not shown) to form a tab 41. The tab 41 is sealed to the tab 22 along a line 40 spaced inwardly of the end of the bandage. The longitudinal edges of the wrappers extend beyond the bandage and are sealed to form an envelope. In use, tabs 22, 41 are pulled apart so that the second wrapper portion 20 may be peeled from the bandage and separated from the tab 22 by which the bandage is held during application to the body. The first wrapper portion is then removed and application of the bandage is completed. The first wrapper portion may extend along the back of the bandage (Fig. 7, not shown), the second wrapper portion being sealed to it at the end remote from the tabs and extending only along the front adhesive-coated side of the bandage. A pack of wrapped bandages 63 (Fig. 10) may be fixed by a staple 65 passing through projecting end tabs 41 to a cover 60, the other tabs 22 facing the cover. In use, the bandage adjacent the cover is released first by a pull on the tab 22 which separates the bandage from the second wrapper portion. The second wrapper portion is then tucked into a strap 64 on the cover so that the next bandage is accessible. The cover may extend around the pack and be closed by tucking one end into a pocket or flap formed at the other end. The pack may alternatively be attached by the tabs 41 to a U-shaped bracket 71 (Fig. 11) which extends from a rigid backing 70 supported on a wall. The other tabs 22 face away from the backing. When a bandage has been released from the second wrapper portion by a pull on its other tab 22, the second wrapper is folded over the bracket 71 to the rear of the pack. Alternatively, a pack of wrapped bandages may be secured by the ends of the wrappers remote from the tabs 22, 41 to a cover or rigid backing. Specification 754,848 is referred to.
