Abstract: Abstract of the invention A  process  for preparing a tetragonal barium  titanate film with a thickness of from about 0.1 millimeter to about 1.5 millimeters is disclosed.     In the first step of this processs there is provided a batch  containing from about 46 to about 54 mole percent  of barium  oxide,  from  about 18 to about 32 mole  percent  of titanium  oxide,  and from about 32 to about 18 mole percent of boron oxide,  wherein each of said reagents is calculated on the oxide basis in mole percent from a barium compound, a titanium compound, and a boron oxide compound in said batch.     In the second step of the process,  the batch is melted at  a temperature of from about 1300 to about  1400  degrees centigrade for from about 25 to about 40 minutes until it is molten.   Thereafter, the temperature of the molten batch is reduced  to  ambient  temperature  in less  than   about  30 seconds, thereby producing glass.    The  glass  produced by quenching is placed upon  an polycrystalline      isostructural      substrate.       The substrate/glass  assembly is subjected to a  temperature  of from  about  1150 to about 1250 degrees centigrade for  from about  10 to 20 minutes until the glass becomes  molten  and flows over the surface of the substrate;     In   the   next   step,    the   temperature   of   the substrate/glass  assembly  is reduced to from about  950  to about 1,050 degrees centigrade.  Thereafter, the temperature of  the  assembly is maintained at from about 950  to  about 1,050  degrees  centigrade  for from about 25  to  about  60 minutes.

Abstract: The deformability measurement chamber is subdivided by a foil into two chamber spaces. The foil has a passage opening, the diameter of which is smaller than the diameter, at rest, of a red blood corpuscle. A static pressure gradient exists between the two chamber spaces, so that a flow takes place from one chamber space to the other. In the region of the passage opening there is situated on each side of the foil an electrode, which is connected to an alternating voltage source. In order to achieve a measurement signal which is approximately one order of magnitude greater, at a given alternating voltage frequency, a current-measuring operational amplifier is disposed in the connecton of one electrode to the voltage source.

Abstract: In a sliding needle bar tufting machine in which displacement of a needle bar transversely of a tufted fabric undergoing manufacture to create a pattern in the fabric is effected by the action of rotary cam means on a needle bar carrier member, the invention provides single or single-acting cam follower means on the needle bar carrier member and a pair or appropriately spaced rotary cams of conjugate shape acting on said cam follower means. The use of two cams of conjugate shape makes it unnecessary for the individual cams to be symmetrical about their centers of rotation and thereby enables the production in the fabric of patterns which are asymmetrical in character.

Date Dec. 18, 1986.Process for recovering chemicals and energy from cellulose waste liquors preferably black kraft liquor obtained in a paper pulp sulphate process, comprising the following, three distinct and separate steps: In the first step the concentrated black liquor is gasified in a pressurized gasification reactor by so called flash-pyrolysis at 700 DEG  to 1300 DEG  C., normally 800 DEG -900 DEG  C., whereby an energy rich gas is produced, and in which the inorganic chemicals of the black liquor are contained in the form of molten suspended droplets, mainly comprising sodium carbonate and sodium sulphide. In the second step the gas from the gasification reactor is rapidly cooled through direct contact with water, and with green liquor, which is formed when the molten droplets and the hydrogen sulphide are dissolved in the quench liquid. The cooled gas subsequently passes through a scrubber. In the lower section of the scrubber the gas is washed with circulating green liquor, and in the upper section of the scrubber the gas is washed with sodium hydroxide (or carbonate) solution and water for complete removal of any remaining sulfur bearing components in the gas. In the third step the now sulfur and particulate-free gas is used as a fuel for generating steam and, if it should be economically justified, also for production of electric power.

Abstract: A process for the production of beer with a low alcohol content is described. The process comprises preparing a wort by boiling and adding ascorbic acid to such wort prior, during, or after boiling, so long as the wort remains hot. The process can be employed according to the invention for the production of non-alcoholic beer by the yeast cold contact process, in which yeast recovered from a fermentation process is brought into contact with the wort at a low temperature below 0 DEG  C. As a rule, the non-alcoholic beer produced by this process imparts an unpleasant and bitter aftertaste. By adding ascorbic acid to the boiling wort, the bitter aftertaste is completely eliminated.

Abstract: Disclosed is a portable continuous infusion apparatus for administering an injectable liquid to a patient. The apparatus expells the contents of a syringe on a time controlled basis. It employs two separate springs, with one spring used to power a clockwork and another spring to power a gear rack to advance the syringe plunger or piston. Opening and shutting the apparatus cover automatically winds both springs simultaneously. A safety prevents closing the cover unless the springs are wound. Advancement of the gear rack is adjustable by a control which acts on an escapement lever which regulates an escape wheel. The control moves the escapement lever axially so it can engage a different number of wings on the escape wheel, thereby regulating the incremental advance of the gear rack acting on the syringe plunger.
