Filed: 1923-02-12
Abstract: 194,277. Stemco Engineering Co., (Assignees of Frank, W. N.). March 2, 1922, [Convention date]. Indicators actuated by floats.-For indicating at a distance the level in a tank, a graduated drum is rotated by a flexible connection such as a chain or wire which is maintained under tension, the wire being connected to a part actuated by a float or like mechanism in the tank, the connection leaving the wire free for movement in one direction. An indicator drum 11, Fig. 5, is mounted on brackets in a case 2 which has an observation window 9 through which are observed the graduations on the periphery. The drum is weighted at 12 to maintain a chain 13 in tension, brackets 54, 55 preventing the balance 12 from passing to the other side of the vertical. The case 2 is adapted to be mounted on the dashboard of a car, aeroplane or like by a U stirrup 6, Fig. 1, and holding screws and nuts 4, 5. A float 40 in the tank has an arm 39 which is secured to a spindle 37, Figs. 3 and 4, mounted in an airtight casing 28 on the tank cover 50. The spindle passes through a stuffing- box 42, or has a cone joint or other similar fluidtight mounting. A cam 38 on the spindle 37 presses against a lever 27 so as to further maintain in tension the wire 14 which is coupled to the drum chain 13.

Title: Improvements in or relating to galvanic batteries
IPC: H01M50/618
Filed: 1935-02-09
Abstract: 451,671. Batteries. SWAN, A., Royal Aircraft Establishment, South Farnborough, Hampshire. Feb. 9, 1935, No. 4238. [Class 53] [See also Group XXIX] Liquid is supplied to a battery through a pipe 10, the supply being automatically controlled by a valve 6 to maintain a constant level of electrolyte in the battery. The valve 6 which may be in the form of a diaphragm normally closes the end of a pipe 8 leading from the supply pipe 10 and is situated in the upper end of a tube 4 projecting downwards into the battery. When the electrolyte falls below the normal level it unseals the lower end of the tube 4. The air pressure in the tube 4 is thus reduced and the pressure of liquid in the pipe 8 opens the valve 6. When the level of the electrolyte in the battery rises sufficiently it closes the tube 4 and the increase of pressure on the air in the tube raises the diaphragm 6 till it closes the end of the pipe 8. The pipe 10 is connected to a reservoir of liquid. Gases liberated in the battery escape through holes 20. The diaphragm 6 may be made of oiled silk or rubber and instead of forming the valve it may carry a valve at its centre. Other types of valve may be used such as a mercury valve or a valve of the piston, liquid or mechanical type.

Title: Process for continuous dyeing with esters of leuco vat dyestuffs
IPC: D06P1/613
Filed: 1963-02-04
Abstract: Textile materials comprising cellulose are dyed in a continuous process by means of an ester of a lenco vat dyestuff wherein a polyglycol ether of the formula <FORM:1018115/D1-D2/1> in which n is an integer from 7 to 10, is added to the padding bath.  The preferred polyglycol ethers are those in which n is 8 or 9.  Long lengths of material e.g. over 3,000 or even 10,000 metres, can be dyed by the present process.  The padding bath may also contain a dispersing agent e.g. a formaldehyde/naphthalene sulphonate condensate.  In the examples the padding treatment is effected at 40-50 DEG C and is followed by a passage in air, development in a sulphuric acid bath, a second passage in air, neutralisation and soaping.

Abstract: 1,076,236. Fastener driving tools. D. HAUBOLD. Feb. 3, 1966 [Feb. 4, 1965], No. 4818/66. Heading B4C. An air-operated tool for driving staples or nails into a workpiece comprises a main cylinder 5, a magnet 29 for holding a piston 14 in its uppermost position, an inlet valve 23 seating on the upper end of the cylinder, an exhaust valve 32 at the upper end of the cylinder and a trigger-operated control valve 42 for pneumatically-moving the inlet and exhaust valves, the exhaust valve being connected to a differential piston 34 operating in a cylinder 35 having a port 39 in permanent communication with an air chamber 4 and a port 40 which is in communication with the air chamber only when the control valve is in its inoperative position as illustrated. In this inoperative position, O- ring 49 is seated while 0-ring 48 is unseated to permit the air in the chamber 4 to pass through ports 53, 40 to the cylinder 35 and to pass through ports 53, 44 into the space above the inlet valve 23. When the trigger 46 is squeezed, the control valve is moved upwardly to the position illustrated in Fig. 3 (not shown), to shut-off the air supply to the space above the inlet valve and to open the port 40, together with the space above the inlet valve, to an exhaust port 54 via ports 53. The differential piston 34 moves to the right to close the exhaust valve 32. The air in the chamber 4 then raises the inlet valve against the action of springs 24 as it passes through ports 45 to force the piston 14 downwardly and drive staples from a magazine 17. During the downward movement of the piston, air is displaced through ports 11 into a storage chamber 9 and when the piston reaches a buffer 13, the actuating air above the piston flows through a port 10 to increase the pressure in the storage chamber for returning the piston. If desired, the cross-sectional area of the port 40 may be varied to regulate the time for discharging the air from the cylinder 35 and closing the exhaust valve 32.

Abstract: 326,957. Jackson, L. Mellersh-, (Mathieson Alkali Works). Feb. 15, 1929. Pulp, preparation of; pulp, catching and recovering.-Chlorine is added to the half stock or fibre-water mixture after its formation in the beaters and before the formation of paper therefrom, or to the raw water used, in sufficient quantity to remove slime therefrom, and the paper is then made before the stock becomes again contaminated with objectionable organic growths. The chlorine added should leave in the stock a residual chlorine content of about to 1 part per million. The sterilization is effected when the stock is at a high dilution and may take place by the addition of chlorine to the stream of diluted stock as it passes through the mixing box ahead of the paper machine. The white water from the sterilized stock is returned for re-use in making additional stock. The process may be combined with coagulation treatment of the stock before the paper making operation as described in Specification 326,956 or with a coagulation treatment of the white water as described in Specification 324,547. Specification 25385/12 also is referred to.
