Abstract: NESTABLE CAN AND METHOD OF MANUFACTURE   ABSTRACT         A nestable can and method of manufacture is described wherein a blank cut from sheet metal stock is drawn into a tapered die with a tapered drawhorn to form a first stage cup having a bottom, a tapered cylindrical sidewall and a peripheral flange.  Care is taken to avoid coining of the sidewall in the first stage of manufacture.  The partially formed can is then reformed by expanding the sidewall while maintaining its taper, thereby removing wrinkles and forming a second stage cup having smooth interior and exterior sidewall surfaces.  The nestable quality of the cup is dependent upon a novel profile created while reforming the first stage cup.  In that operation the upper end of the cup is reshaped to form an upper rim that is off-set from a tapered sidewall and having convex contact surfaces that support one cup within another.  The location of the contact surfaces is such that adjacent sidewalls of two nested cups are spaced apart by at least .0015 inch, the peripheral rims being vertically spaced by at least .140 inch to facilitate cup separation.

Abstract: ABSTRACT:       A flat display tube comprising an envelope including a faceplate on which a luminescent screen is provided.  An internal divider divides the interior of the envelope vertically into a front portion adjoining the faceplate and a rear portion which communi-cates with the front portion via a space between the upper edge of the divider and a peripheral wall of the envelope.  An upwardly directed electron gun and line scanning means are disposed in the rear portion.  The line deflected electron bean is directed to a 180° reversing lens which deflects the electron beam into the front por-tion.  An electron multiplier is disposed in the front portion adjacent to, but spaced from, the faceplate.  The electron beam in the front portion undergoes frame deflection by means of a plurality of selectively energised, vertically spaced, horizontally elongate electrodes.  The pattern of energisation of the electrodes is such as to deflect an end portion of the electron beam to the input side of the electron multiplier.  The beam having undergone electron multiplication is accelerated to the screen.

As instructions are fetched from the main memory, the instructions are partially decoded by adding the stack pointer to the offset and the result is then stored in an instruction cache.  In cases where the sum of the memory locations required by the procedures exceed available register memory, the contents of the registers nearest the maximum stack pointer are flushed back to main memory.

Abstract: METHOD OF PROTECTING A THYRISTOR SWITCH OF A     PULSE GENERATOR.                    ABSTRACT      To  protect  a  thyristor  switch   in   a   pulse generator  for  an  electrostatic  precipitator  it  is desirable  to  control  the  spark-over  rate  in   the precipitator.    A   first    spark-over    starts    a measurement of the difference  between  the  number  of spark-overs and the  number  of  times  a  pre-selected cooling  period  (Pk)  has  passed  after   the   first spark-over and the  measurement  is  stopped  when  the difference  becomes  0.   The  measurement  is  started again the next time a  spark-over  occurs  and  one  or more relevant running parameters  of  the  precipitator are influenced  in  such  a  way  as  to diminish  the probability  of   a further   spark-over   when   the difference exceeds a given value.

Abstract: METHOD FOR FORMING VIDEO DISCS    ABSTRACT OF THE DISCLOSURE      Methods for use in producing a disc-shaped recording master having a thin  photoresist recording layer for storing an f.m. information signal with high density.  During recording, an intensity-modulated writing beam is focused onto the photoresist layer, to form a succession of spaced exposed regions arranged in a plurality of substantially circular and concentric recording tracks.  The master further includes a glass substrate having a specially prepared surface, and the photoresist layer is deposited on the surface using a technique that ensures a uniform thickness and a uniform sensitivity to the writing beam.  The peak intensity of the writing beam is selectively adjusted such that the succession of spaced exposed regions is formed with an optimum 50/50 duty cycle.  After development to remove the spaced exposed regions, the recording master is used to produce a metallic stamper that, in turn, is used to produce disc replicas. In applying the photoresist the substrate is first rotated at a first velocity during which the photoresist is dispensed after which the substrate is rotated at a second velocity to dry the photoresist to a prescribed percentage dryness. Complete drying is then effected by baking.

Abstract: ABSTRACT OF THE INVENTION         A  voice-controlled  elevator  security  system.          Access  to  an elevator  system  servicing a plurality of landings of a structure is controlled by comparing a voice signal of a potential user of the elevator system with stored voice signals of all authorized users.  The compar-ison  is  accomplished by first digitizing the potential user's voice signal  and comparing  it,  on  a bit-by-bit basis, with a digital representation of the voice signals of all authorized users.  Various criteria can be estab-lished for determining the number of binary bits that must agree to conclude that the potential user is an authorized user.  Once this determination has been made, the author-ized user can initiate car call signals for those landings to which the authorized user is permitted access.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention pertains to a method and apparatus for processing contaminated water containing high concen-trates of volatile and soluble inorganic and organic com-pounds and ion reaction complexes thereof, and particularly pertains to the removal of high concentrations of hydrogen sulfide from well water, and the invention is well suited for use with domestic water systems.  Batches of untreated water are introduced into a vented first holding chamber at a rate and volume related to the removal of batches of treated water from a second holding chamber.  The chambers are interconnected by a dilution flow control orifice, or orifices, and air and ozone are mixed with the water within both chambers wherein aeration by air-stripping within the first chamber rapidly reduces the high hydrogen sulfide con-centration and the lower hydrogen sulfide content of the water within the second chamber is primarily removed by the ozone.  Effective ozonization within the second chamber is assured by stratifying the second chamber water by producing a vortex therein, and the rate of dilution of the water within the  first chamber as it is transferred into the se-cond chamber is controlled by the dilution flow control ori-fice.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to mixtures of sulfonated thermoplastic polymers and amine-treated clays which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits and lift cuttings from the holes in the drilling operation for oil and gas wells.  The sulfonated thermoplastic poly-mers have 5 to 100 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic polymer, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion.  A polar cosolvent can optionally be added to the mixture of oil drilling mud and  sulfonated thermoplastic polymer, wherein the polar cosolvent increases the solubility of the sulfonated thermoplastic polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymer.
