Abstract: ABSTRACT OF THE DISCLOSURE          In a high pressure fluid system for providing fluid to a hand held nozzle, an improved power assisted dump valve which may be remotely located and controlled. The dump valve includes a stepped piston positioned in a stepped bore with one end of the piston adapted for sealing off a pressure relief outlet.  A fluid conduit, preferably a passageway through the piston, conducts high pressure fluid to the valve chamber at the large diameter end of the piston.  A control valve either seals off the large diameter end of the chamber or vents it to ambient pressure so that differential pressure supplied by the working fluid itself drives the valve piston to its open or closed positions.  An electrical, hydraulic, or mechanical actu-ator operates the control valve, remotely if desired, to control the flow of high pressure fluid to the nozzle.

Abstract: O.Z. 0050/034411 ABSTRACT OF THE DISCLOSURE:     A process for the preparation of a textile finish, the finish thus obtained and its use for the easy--care finishing of textiles containing, or consisting of cellulose.          The finish comprises an aqueous solution, of from 30 to 70 per cent strength by weight, of a mixture of the conventionally methylolated (= hydroxymethylated) carbamates I and II                                      I                                      II where R is hydrogen or alkyl of 1 to 4 carbon atoms, in the weight ratio I : II of from 1 : 1 to 1 : 20.  The finish is prepared by reacting a glycol or an alkylgylcol of the formula III                    R-(OCH2-CH2)9-100-OH                  III where R has the above meanings, and isobutanol with urea at above 100°C, so as to eliminate ammonia and produce carbamates, and methylolation with formaldehyde. In a first stage, the glycol or alkylglycol of the formula III is reacted to the extent of at least 50% with urea, in the absence of a catalyst; at from 130 to 160°C, to give the carbamate I, and in a second stage, carried out either in the presence of an ion exchanger containing nickel ion  at from 130 to 165°C, or in the absence of a catalyst at from 150 to 200°C  the carbamate mixture in the weight ratio I : II of from 1 : 1 to 1 : 20 is prepared by addition of isobutanol and further urea.

Abstract: ABSTRACT OF THE DISCLOSURE  ._ A horizontal shell boiler has a horizontal furnace section which communicates with a flue gas transfer section at its end which transfers the flue gases from the furnace section to flue tubes extending horizontally through the space between the furnace section and the shell of the boiler.   The furnace section is designed for fluidised bed combustion and has a flue gas transfer tube extending horizontally through its upper  portion. The tube has hollow walls connected to the boiler fluid surrounding the furnace section and has apertures formed in its hollow wall through which furnace gases can enter the tube.  The furnace gases after entering the flue gas transfer tube travel horizontally and do not entrain material of the fluidised bed.

Abstract: ABSTRACT           A fluid operable hammer has a hammer piston reciprocably slidable in an elongated bore of a body member so as to provide work and return strokes.  Reciprocation is achieved by hydraulic fluid under pressure, which fluid exhausts into an exhaust fluid receiver.  The exhaust fluid receiver includes a variable volume exhaust chamber which is maintained in intermittent fluid communication with the bore, the chamber having minimum and maximum volumes.  The differential volume between the minimum and maximum volumes is substantially no less than the displacement of the piston within the bore.

Abstract: METHOD AND APPARATUS FOR MEASUREMENT OF        ENGINE IGNITION TIMING                  Abstract of the Disclosure Method and apparatus for measuring ignition timing of an internal combustion engine wherein angular position of the engine crankshaft is monitored while microwave radiation is injected into a selected engine cylinder. An angular position of the engine crankshaft at an apparent top dead center position of the piston in the selected cylinder is identified as a function of micro-wave resonances within the cylinder.  The angle of piston top dead center position is then compared with an event correlated with ignition at the selected cylinder to determine the ignition angle relative to the piston top dead center position.  Ignition timing may then be adjusted to obtain a desired angular relationship between ignition and piston top dead center.

Abstract: A PRESSURE VESSEL Abstract of the Disclosure This invention relates to an inexpensive pressure vessel of the type which can be disposed of rather than being repaired once it fails.  The pressure vessel includes a cylindrical housing having two chambers separated by a resilient bladder.  One cham-ber is for housing a gas while the second is for housing a fluid such as hydraulic oil.  The cylindrical housing contains a port at one end and is open at the opposite end.  The end cap which contains a through port and a gas valve is insertable into the open end of the cylindrical housing and is welded thereto.  This weld joint in conjunction with a seal formed by attaching the resilient bladder to the end cap, will positively seal the pres-sure vessel.  The unique seal between the end cap, bladder and housing is such that it will not be thermally damaged by the welding process which seals the end cap to the cylindrical hous-ing.
