Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an air flow system for a vacuum cleaner which, because of the nature of the machine, must be able to operate in wet or damp environments without the ingestion of water into the motor.  The housing for the motor is of a bulbous shape manufactured of an insulating material and is arranged to have a bulbous shaped insulating cap fitted on the housing in a spaced apart relationship, such that two air flow channels are produced between the housing and cap by a pair of rib structures integrally cast in said housing structure.  Air is drawn into the bottom of the cap and moves upwardly between housing and cap, passes through the housing and through the motor fan, through the motor to provide the necessary cooling and thence is expelled to atmosphere by passage out of ports in the housing to pass into another section of the housing-cap structure.

Abstract: ABSTRACT A probe for measuring coordinate positions on an object by sensing a displacement of the stylus which contacts the object.  The probe is responsive to forces which result from the contact between the object and the stylus to indicate coordinate positions of the object.  The probe includes a replaceable stylus having a shank portion defining an axis, with a transversely-extending portion extending from the shank portion for sensing forces exerted by objects in the axial direction away from the probe, while the stylus shank portion is responsive to forces in the radial and axial (toward the probe) directions.  The probe is thus responsive to forces exerted on the stylus in any direction.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to a process of producing sulfuric acid from waste sulfuric acid, which contains iron sulfate and has become available as a result of a solubilizing treatment of TiO2-containing materials with sulfuric acid, in which process ferrous sulfate having a high content of water of crystallization is transformed to ferrous sulfate having a low content of water of crystallization and the latter is filtered off as solids, the sulfuric acid concentration of the aqueous filtrate is increased by an evaporation of water, a partial stream of the filtrate of increased concentration is added to the waste sulfuric acid, and sulfuric acid is recovered from the solid iron sulfate which has been filtered off and has a low content of water of crystallization.  It is an object of the invention to enable an economical and ecologically satisfactory processing of the waste acid and of the solid ferrous sulfate.

Abstract: QUICK TAKE-UP MASTER CYLINDER            Abstract of the Disclosure:          A master cylinder assembly has a low pressure, high volume displacement quick take-up chamber and a high pressure, low volume displacement pressurizing chamber formed by a stepped bore and a stepped piston.  A compensation control and blow-off valve unit has a peripheral lip seal type valve providing compensation flow on brake release but preventing flow from the quick take-up chamber during brake apply.  A normally closed check valve is held open while the master cylinder is in the fully released position to provide communication between both pressurizing chambers and the fluid reservoir.  As the pressur-izing cup for the high pressure chamber closes its compensation port, the check valve is permitted to close by camming action of a valve pin and a camming surface on the piston.  Initial fluid flow is obtained from the quick take-up chamber past the pressurizing cup into the high pressure chamber.  At a pre-determined pressure level, arranged to be sufficient to take up lining clearance and initially apply the vehicle brakes, the pressure in the quick take-up chamber opens the normally closed check valve so that fluid from the quick take-up chamber then flows to the reservoir without further pressure buildup in that chamber.  As the master cylinder is released, compensation fluid can flow past the peripheral compensation valve to both chambers.  When the master cylinder is returned to the fully released position, the check valve is forced open by action of the piston cam surface and the valve pin to provide fluid communication between the reservoir and both pressurizing chambers.  A fluid flow restrictive orifice is provided in series with the normally closed check valve to prevent a high rate of pressure increase in the quick take-up chamber from being bypassed fully to the fluid reservoir upon a high rate of master cylinder actuation, forcing at least some of the pressure to pass by the cup seal into the high pressure chamber and the brake apply circuit.

Abstract: SYSTEM AND METHOD FOR KEYING VIDEO INFORMATION            TO ELECTRON BEAM DEFLECTION                           Abstract In an image display, the video information is keyed to the position of the electron beam by sensing the beam deflection voltage. The keying system utilizes means for generating a reference voltage which is proportional to the anode voltage,and means for comparing the reference voltage with the deflection voltage for the electron beam.  When a predetermined relationship between the two voltages, such as equality, is reached, the comparing means produces an output which indicates the deflected position of the electron beam.          The output of the comparing means can be used to switch the video information to modulate the electron beam.

Abstract: ABSTRACT OF THE DISCLOSURE           A water-conserving toilet is disclosed and includes a bowl for receiving waste and a waste outlet extending laterally from the bowl and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl for preventing gaseous flow through the trap.  A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl in a direction to cause said body of liquid to be dis-charged through said outlet.  A waste holding tank communicates with said bowl outlet for receiving waste from the bowl and the holding tank has an outlet ex-tending outwardly from the tank and adapted for connection to a sewer inlet.  The holding tank outlet defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the holding tank in use and the holding tank and second trap are arranged to contain a volume of liquid substantially in excess of the volume discharged from the bowl at each flush. A flexible diaphragm extends across the holding tank above the level at which liquid enters from the howl and is sealed to the tank in gas-tight fashion.  The diaphragm is adapted to flex upwardly and accommodate air displaced as liquid enters the tank from the bowl, so as to minimize air resistance to flushing of liquid from the bowl.

Abstract: ABSTRACT OF THE DISCLOSURE         An extruded tubular blank is placed in a mould such that it is divided into two portions connected by a conduit coaxial with a blowing needle.  A first one of the portions is blown to form a container, whereas the second is not blown and remains hot and mallable.  The walls of the second portion are then compressed one against the other and welded together to close the blowing orifice.  In order to carry out this method, the mould comprises two chambers, and a blowing conduit which starts from one of the chambers, passes through the other and opens out on the outside.  The blowing needle slides in this pipe in an air-tight manner so as to inflate solely the first chamber.  A flat head driven by a piston moves in the second chamber in order to crush and weld together the walls of the unblown second blank portion.  Alternatively the second blank portion may be crushed by compressed air.
