Title: Process for the production of insoluble coatings, impregnations, pressed masses and the like
IPC: C08C19/14
Filed: 1935-08-19
Abstract: Chlorinated rubber is rendered insoluble in solvents by treatment with organic bases having a dissociation constant of 10<-5> and over. The treatment may be at ordinary or elevated temperature, the bases being in vaporous, liquid or solid form. The treatment is particularly useful where the chlorinated rubber is used as a lacquer, as an impregnating medium or for pressed products.  Various amines are cited as examples of bases.  In the production of a lacquer a solution of chlorinated rubber in toluene is treated with the base and the lacquer applied at once before a gel is formed.  In making pressed products the dry chlorinated rubber may be mixed with the base and with fillers and hot pressed.  In examples: (1) a solution of chlorinated rubber in toluene is treated with piperidine to give a lacquer, (2) chlorinated rubber is kneaded with naphthalene and tetramethylene-diamine to give a product for hot moulding, (3) a fabric impregnated or coated with chlorinated rubber is hung in an atmosphere containing methylamine.ALSO:Chlorinated rubber is rendered insoluble in solvents by treatment with organic bases having a dissociation constant of 10-5 and over.

Title: An improved method and apparatus for measuring the quantity of steam, gas, air, water or the like flowing through a pipe
IPC: G01F5/00
Filed: 1923-09-20
Abstract: 221,089. W³nsch, G., and Askania- Werke Akt.-Ges., vorm. Centralwerkstatt-Dessau und C. Bamberg- Friedenau. Sept. 20, 1923. Flow meters, pressure-actuated.-The total flow of steam, gas, air, water &c. in a pipe a, Fig. 1, is measured by connecting the pipe in front of and behind a resistance such as a throttling ring b by pipes c, d to a casing e containing a diaphragm i, and measuring the escape of steam &c. through a needle valve n operated by the diaphragm i to a measuring vessel o. The pipe c is fitted with a throttling ring r, the opening in which bears the same ratio to the pipe c as the opening in the ring b does to the pipe a so that the flow of steam through the pipe c to the measuring vessel is proportional to the flow of steam through the pipe a. The pipe d is fitted with a similar ring g or shaped to provide the same, resistance as the pipe c in order to prevent sudden changes of pressure on the diaphragm. Similar means may be used to determine the flow from the casing e. In a device shown in Fig. 2 suitable for measuring the flow of steam, the pipe c opens into a chamber f in which the casing e containing the thin metal diaphragm i is arranged. The upper chamber s of the casing e communicates with the chamber f through a branch c' containing the throttling ring r. The lower chamber t of the casing e communicates with the pipe d through a pipe d' containing a throttling ring g of practically the same dimensions as the throttling ring r. A leak k allows a small escape of steam from the chamber f to the pipe d. The diaphragmoperated valve n through which steam escapes to the measuring vessel o may be arranged to act as an injector and induce a flow of air through holes u from a chamber v. The chamber u is connected to a pressure gauge x by a pipe w having a high resistance leak z to the atinosphere. The reading on the gauge x indicates the rate at which steam is being consumed.

Variable-speed and reversing gearing comprises at least one rolling element such as a having teeth c engaging a ring of holes f in a disc or plate d supported at its back by a friction-clutch member k, the power passing across the frictionclutch surfaces i, j, Fig. 3. A single pinion a may be moved laterally between two discs d, e to drive them alternatively in opposite directions, cr separate pinions a, b may be used movable on their shaft g to drive two discs d, e at different speeds in either direction. The shaft g is supported in blocks r, s, Fig. 2, which are held down by a medially-pivoted spring t so that snugs u are held against cams x, Fig. 1. These cams have central notches for the neutral position, and lateral inclines against which the snugs u are thrust by the spring t, the effect being to wedge the pinions a, b against the discs d, e, and the latter against the clutch members k, l. When the speed is to be varied, the pinions a, b are made to approach or recede from one another by a double screwed rod 8. As applied to a motor-vehicle, the clutch members k, l drive the road wheels separately, and the wheel on the outer curve is allowed to overrun by disengaging its clutch. For this purpose, the block r or s corresponding is raised, so that the snug u rides up on the cam x, so that the wedging action no longer takes place. Rollers 6, Fig. 1, engaging the bases of the blocks r,. s are suitably operated by the steering-mechanism. Specifications 10144/04 and 18776/14 are referred to.

Filed: 1937-08-31
Abstract: 484,955. Delivering measured quantities of liquids. BRUNE. H. Aug. 31, 1937, No. 23808. [Class 106 (v)] A device for delivering measured quantities of liquid from a bottle or other container comprises a measuring chamber, each end or each end member of which is provided with apertures arranged in a straight line non-parallel with the straight line on which lie the apertures of the other end or end member. As shown in Fig. 1, the neck 2 of a container 1 is formed into a measuring chamber 8 by parallel end members 4 and 5 each provided with two holes at opposite ends of a diameter. By tilting the container with the inlet holes 6 in a vertical plane and the outlet holes 7 in a horizontal plane, liquid can pass into the measuring chamber through the lower hole 6, air escaping through the upper hole 6 but no flow can occur at the holes 7. When the chamber 8 is filled the container is rotated through 90‹ into the position-shown. This allows the discharge of the measuring chamber. The holes may be formed in the sides of the neck around the edges of the end members or the two holes may be replaced by a narrow slot. As shown in Fig. 12 if the end members 30, 31 are not parallel the holes 32, 33 may be in the same plane, the charge and discharge of the chamber then being controlled by tilting the container so that one or other set of holes is horizontal. The outside of the neck may be provided with grooves 36 to assist the formation of drops of equal size. The measuring chamber may be separate from the container and connected thereto by piping.

Abstract: 1,113,840. Batteries. SVENSKA ACKUMULATOR A. B. JUNGNER. 27 May, 1966 [28 May, 1965], No. 23932/66. Heading H1B. The electrodes of storage batteries consisting of one or more cells may be clipped together at their lower ends. The clip may be U-shaped its arms pointing upward when in use and gripping the outer faces of a stack of plate electrodes. The yoke of the clip may be a straight rib the parts of the arms adjacent to it being perpendicular to it or bent slightly inward and the remainder of the arms being bent outward so that when the clipped electrode stack is inserted into its cell the arms of the clip press on the cell walls and hold the electrode still. The extremities of the arms may project outward in such a way that when the electrode is inserted in the cell these projections rest on shoulders on the walls of the cell. The electrodes may thus be temporarily held in a position where they project from the top of the cell so that they can be welded or soldered to adjacent electrodes before all the electrodes are simultaneously pressed down into their final positions in the battery. A vertical section through part of a battery according to the invention is shown in Fig. 1. Electrode groups I and II consist of alternate positive and negative plates separated by separators. They are clipped at their lower ends by clips 6 and lowered into cells IV and V until projections 15 engage on shoulders 18. After the electrodes have been joined up they are pressed home and clips 6 rest on ridges 10 (Fig. 2, not shown). Figs. 5a and 6a illustrate alternative clips.

Patent GB-1026452-A (GB)
Title: Improvements in or relating to indicating devices
IPC: G01N31/22
Filed: 1962-11-07
Abstract: A device for indicating the chemical composition of liquids and gases comprises a porous capillary material and an impervious covering material completely or substantially completely enclosing the capillary material and in intimate contact with, one portion of the capillary material being exposed to the fluid during use, the properties of the capillary material varying in the direction of fluid absorption from the portion thereof adapted to be exposed to fluid.  The variation may be in the porosity or in the shape.  An impregnant may be incorporated in the capillary material to provide a visual indication of the depth of penetration of a test fluid or selected component thereof.  A graduated scale may be associated with the capillary material to determine the depth of penetration of the fluid.  The capillary material may be, for example, of cellulosic, synthetic or glass fibres or of granular materials, spongy or cellular materials. The sheathing material may be made of a plastics film e.g. polyethylene, other materials also being specified, and may be translucent or transparent.  The sheathing material may be laminated on to the capillary material, or the latter may be dipped or sprayed, e.g. with a high solids content thermoplastic resin solution, or treated by conventional roller coating techniques.  It may also be secured by means of an adhesive such as pressure-sensitive adhesives.  The Figures (not shown) illustrate a variety of shapes of the devices.  The capillary material may be made in a single piece, or may be in portions of differing properties.  If the capillary material is impregnated with reactive materials, these may be fixed to the surfaces of the capillary material or may move with the fluids.  In the former case, for example, an ion exchange resin may be incorporated on the surface of the capillary material or may be used as the porous capillary material itself.  Suitable indicators may be incorporated therewith.  The concentration of a solute in a solvent may be determined by measuring the height of rise of the material in the device: dye solutions may be determined in this way.  For the determination of HCl or NaOH a suitable indicator such as methyl red or phenolphthalein may be impregnated in the capillary material: for the determination of sodium chloride both silver nitrate and dichlorofluorescein may be incorporated.  If so desired only an end portion of the capillary material may be impregnated with the reagent, e.g. bromothymol blue may be thus impregnated.  For the determination of milk, a capillary material comprising an ion exchange material is treated with NaOH to produce the hydroxide form and then dried.  The material is then impregnated with a methyl red indicator and again dried.
