Abstract: ABSTRACT OF THE DISCLOSURE         A novel method is provided for the production of anhydrous hydrofluoric acid from low grade metallic fluorides using an intermediate aluminum fluoride compound.  The method involves the reaction of low-grade metallic fluorides such as fluorspar with sulfuric acid to produce weak hydrofluoric acid.          The weak acid is then reacted with a metallic salt (such as aluminum chloride) to form precipitated aluminum fluoride (AlF3?3H2O).  After dewatering, the aluminum fluoride is reacted with strong sulfuric acid to form aluminum sulfate and strong hydrofluoric acid.

Abstract: COSMETIC CONTAINER CONSTRUCTION              ABSTRACT OF THE DISCLOSURE      The invention contemplates a cosmetic-container of the propel-repel variety wherein all parts are assembled and retained by interference fit and wherein metal-to-plastic interfaces characterize essentially all sliding engagements.  The arrangement is such as to provide a luxury "feel" through con-trolled drag torque (resistance) to relative rotation of the parts.  And provision is made to positively retain any retracted position of the pomade carrier, whatever the remaining useful extent of involved pomade.

Abstract: Abstract:    A three dimensional imaging system operating in accordance with the known active triangulation method employs a laser beam that is projected onto an area of a surface the profile of which is to be examined.  A beam reflected from such area is received in a position sensitive detector.  With synchronised scanning of the projected and detected beams by a system of mirrors, the detected position in the detector remains unchanged when the surface under examination is a flat reference plane, changing only as a measure of the degree of deviation of each examined area from such reference plane in a direction Z.  The system is characterised by this basic scanning being carried out in such a way that the beams are scanned in a direction X lying in the beam plane, i.e. the plane defined by the beams, and by a further simultaneous and synchronous scanning that takes place in a direction Y.  The directions X, Y and Z are all mutually perpendicular.  The system has the advantage over prior systems of enabling surface profiling by means of a device that is compact, has a large field of view and can be arranged to have extremely rapid operation, i.e. a small fraction of a second to record a full image.  While this speed of operation enables the system to determine the three dimensional shape of moving articles it has the advantage that it is not dependent on movement of the article to achieve full scanning.

Abstract: ABSTRACT         The present invention provides an electrode which uses a disordered active material preferably formed by rapid solidification.  The active material does not need a binder to be used as an electrode, and thus, is considered self-supporting.  The material also is substan-tially nonporous or impermeable to an electrolyte and when used as an electrode exhibits an increase in cell capacity with improved resistance to corrosion.  An elec-trode of the present invention provides greatly improved cycle life and energy density without a significant decrease in cell capacity.  Methods of making the elec-trode by rapidly solidifying a disordered material are also included.  A method of assembling an electrochemical cell using a self-supporting electrode includes the step of producing a disordered active material and aligning the material in a predetermined position in a cell casing.

The tire has a radial carcass anchored in the tire beads, a tread strip, respective shoulder-like extensions which are each formed by a step, are disposed on each side of the tread strip, and do not come into contact with the roadway under normal driving conditions, and a belt which extends laterally to within the vicinity of each step extension to such an extent that a given one of the belt portions which is disposed within the vicinity of a given step ex-tension has a width equal to approximately 25 - 40% of the amount by which the widest part of the tire extends beyond the end of the tread strip at that given step extension. To achieve a low rolling re-sistance and at the same time a great travel comfort, the beads of the tire are disposed axially inwardly on the rim to such an extent that the beads are dis-posed completely axially inwardly of the step exten-sions.  Furthermore, the carcass neutral line essen-tially conforms to the membrane theory in the region of the sidewalls of the tire.

Abstract: ABSTRACT OF THE DISCLOSURE     A method is provided for measuring and controlling the level of an elevated temperature liquid in a container.          The method includes converting electrical voltage signals from temperature sensing means spaced along a wall of the container to digital form.  The converted signals are periodically scanned in elevation sequence.  From the scanned signals the location is determined of the uppermost sensing means having a signal value of sufficient magnitude to lie below the liquid level.  A fraction, F, of the spacing between that sensing means and the next above sensing means is calculated at which the measured liquid level lies.  The fraction determined is a function of the converted signal value, Sn-1, a converted signal value, Se, at an estimated location of the liquid level and, So, a converted signal value sufficient to cause the fraction, F, to be at or near zero in value immediately prior to imminent changes in the location of the uppermost sensing means determined to lie below the liquid level.

Abstract: ABSTRACT OF THE DISCLOSURE:         Agglomerated particles of finely divided fabric softening bentonite and sodium sulfate particles have been found to possess improved fabric softening properties, compared to agglomerated bentonite, especially when employed in the hand washing of laundry which is subsequently line dried.  Such agglomerates are also of excellent particle strength and are readily dispersible in water.  The described product may be made by agglomerating finely divided bentonite and sodium sulfate powders with the aid of excess moisture, after which the agglomerated particles resulting are dried and those of desired size, preferably in the No's. 30 to 100 sieve size range (U.S.), are obtained.  The fabric softening agglomerate made may be mixed with spray dried synthetic organic anionic detergent composition beads of about the same or lower bulk density, preferably in the 0.3 to 0.5 g./cc. range, with about 5 to 30% of the agglomerate particles being present, to make a non-segregating fabric softening particulate detergent composition of improved softening properties.  Detergency, soil anti-redeposition properties, bead physical characteristics and processing are improved by the presence in the detergent composition of a minor proportion of a water soluble copolymer of maleic and acrylic acids which, unlike other polymers which can impart such properties to detergent compositions, does not adversely affect the softening of hand washed laundry by the present agglomerate.  Soda ash may be used in place  of some or all of the sodium sulfate of the agglomerate and a good softening additive will also be obtained.
