Abstract: ABSTRACT OF THE DISCLOSURE           A current spreading circuit which in a pre-ferred embodiment  is  constructed as a power supply circuit  having  higher  power  factor  and  decreased current  crest  factor.   The circuit preferably com-prises  an  input  circuit  for  receiving  an input AC voltage  and  rectifying this  voltage  and an output circuit for providing a DC output voltage.  A pulse-width-modulator  intercouples  between  the  input  and output  circuits  and  includes  a  portion  which  is adapted  to  pass  input  AC  current  in  pulse-width increments with  the pulse-width varying  in  inverse proportion to the AC voltage.   In this manner, when the instantaneous AC voltage is low, the pulse widths are wider and conversely when the voltage is high, the pulse widths are narrower. In one version of the invention, the pulse width modulation is carried out by a programmed variable ratio transformer.   In one preferred embodiment of  the present  invention,  the current  spreading  circuit  is  of  a quasi   cosecant type  while  in  another preferred embodiment  of  the invention,  there  is  a   combination of pulse-width-modulation with a typical input filter circuit includ-ing an OR circuit at the output to provide the neces-sary combining.

Abstract: STABILIZED CHOCOLATE FLAVOURING SYRUPS, AND ENZYMATIC PROCESS FOR                        MANUFACTURING SAME. ABSTRACT OF THE DISCLOSURE     Chocolate flavouring syrups having a high cocoa content, and consistently  having  excellent  stability and fluidity  at  room temperature, from batch to batch, are prepared by first cooking a mixture of water -- which may be with sugar or a sugar mixture --and  cocoa  at  at  least  80  degrees  centigrade,  with  gentle agitation, for a relatively short period of time; thereafter, the mixture is cooled and an enzyme (alpha-amylase,  glucoamylase, or mixtures  thereof) is added.   The pH may be adjusted before  the enzyme is added.   Thereafter,  the mixtures is again heated  and cooked,  and other ingredients such as stabilizers and sweeteners or additional sweeteners may be added at that time.   The initial cooking  permits  gelatinization  of the starch  content  of  the cocoa,   which  then  becomes  hydrophylic,  and  thereafter  the hydrophylic  gelatinized  starch particles are hydrolyzed by  the enzyme action.   The molecular size of the particles is very much reduced,  so  that  the  contribution  of  large  molecular  size particles  to viscosity is minimized,  giving a product  that  is much  easier  to  handle and that is consistently fluid  at  room temperatures from batch to batch.

Abstract: ABSTRACT APPARATUS AND METHOD FOR THE CONTINUOUS           CASTING OF METAL      In an apparatus  for  the  continuous  casting  of metal,  especially  with  a  casting   machine   having circulating moulds (11), the  metal  flows  as a  melt out  of a  nozzle,  if  appropriate  with   a  nozzle mouthpiece (2), between moulds and  solidifies  between side-limiting  elements.   The   mouthpiece   (2)   has adjoining it on each of its  two  sides  a  baffle  (6) which  is  followed  in  the  casting  direction  by  a cooling block (8). Between the baffle (6)  and  cooling block (8) there is a gap (9) through which a  gas  (10) can be blown into a corner region (11)  formed  by  the baffle (6), cooling block (8) and melt  (3),  this  gas forming a gas cushion in this corner region  (11).  The throughflow  width  (b1)  of  the  molten   metal   (3) between the baffles (6) located  opposite  one  another can be changed as a  result  of  the  movement  of the baffles (6) in the direction (X).

Abstract: ABSTRACT     Mouse monoclonal antibodies to several cell antigens of human ovarian, cervical and endometrial carcinomas have been produced and characterized.  The distribution of the antigens was determined by mixed hemagglutination assays on 153 normal and malignant cell cultures of various types, and by immunoperoxidase staining of frozen sections of 27 normal adult and 24 fetal tissues. five monoclonal antibodies representative of five classes of mAb raised to restricted ovarian, cervical and endometrial cells were tested extensively producing mAb reactive with cancer but not normal cells.  One such mAb, MF116 was readily detected in the spent culture medium of metabolically radiolabeled cells.  These antibodies, reacting with relatively restricted cell surface antigens, are useful in the analysis of epithelial cell differentiation, in cancer diagnosis and therapy and in tissue typing of normal or abnormal cells.

Abstract: ABSTRACT OF THE DISCLOSURE          There is described a high speed axial flow type gas laser oscillator in which the flow rates of the laser gas inside the laser tubes will be more or less equal, in which the lengths of the recirculation paths from the laser tubes to the heat exchanger or cooler will remain approximately equal even if the number of tubes is increased or decreased.  Further, the electrical discharges between the electrodes of the laser tubes and the heat exchanger are suppressed, reducing the loss of electric power used for injection and suppressing excessive heating of the laser gas, and, in addition, reducing the additional load on the heat exchanger or cooler.  Also the removal and replacement of the electrodes in the laser tubes can be carried out easily without displacing the tubes in the axial direction.  The vibrations in the blower which is used to circulate laser gas to the laser tubes are not transmitted to each of the tubes, and, moreover, it is possible to compensate for thermal deformation in the connections between the blower and the laser tubes.     Additionally, the support plates which support both ends of the laser tubes are able to move slightly to compensate for expansion and contraction of the tie rods which are coupled to each support plate.

Abstract: Abstract of the Disclosure A tunnel-type boat hull construction is operative with substantially reduced frictional resistance in the water and also with improved high-speed stability. An air-withdrawal port is provided in the bow portion of the tunnel, and exit ports which are interconnected to the withdrawal port are provided along generally downwardly facing submerged surfaces of the hull.          When the boat hull is operated in a forward direction, air is captured in the forward portion of the tunnel, and a portion of the air is withdrawn through the withdrawal port and is exited through the exit ports. The air which is exited through the exit ports provides lubrication for the submerged hull surfaces so that the hull is operative with substantially improved efficiency; and because the air is withdrawn from the bow portion of the tunnel, the bow uplift effects which are characteristic of conventional tunnel-hull-type vessels when they have been operated under high-speed conditions are substantially reduced.
