Abstract: TITLE:  SELF-ADVANCING TEACHING DEVICE                  ABSTRACT           A time teaching device which gives a numerical readout to teach a child the position of clock hands and is capable of advancing the clock hands every time the child activates the readout portion has a housing in which is located a clock face and typical hour and minute clock hands.  Within the housing are two carrier members which have a plurality of indicia thereon which indicate numerically the position of the clock's hands.  The carrier members are located in the housing beneath display openings.  Interspaced between the display openings and the carriers is an interference member which normally interferes with viewing of the indicia on the carrier.  Both the hands and the carriers are coordinated such that movement of the minute hand will move the hour hand and both of the carriers through appropriate increments.  An operator member is located on the housing and when it is depressed into the housing the indicia corresponding to the positions of the hands is viewable.  Upon release of the operator member the interference member interferes with viewing of the indicia while simul-taneously the hands advance an increment of time and concurrently unseen to the child the indicia carriers move to advance the indicia to correspond to the new positions of the hands.

Abstract: Apparatus and Method for Separation of Optical Character Recognition Data Abstract An apparatus and method is described for the separation of data from adjacent characters of standard type fonts, some of which character pairs may kern or touch.  Charac-ters which do not kern or touch are separated by white column detection.  Characters which do kern are first detected by a kerning test, which consists of locating white bits which separate the characters while meeting pre-established standards of contiguity.  Touching characters are detected by failure to pass the white column test, followed by failure to pass the kerning test.  Characters which touch are separated by a statistical analysis, which involves determination of which of several probable vertical data columns has the least number of character bits.  Following separation, the characters are compared with pre-established character patterns.

Abstract: Abstract of the Disclosure The present invention relates to a bread dough for standard white bread which incorporates pea flour in an amount between about 2% to 3%.  It has been discovered that pea flour in such a relatively small amount acts to substantially reduce dough mixing time, to increase fermentation aroma, and to obtain improved taste in the bread, and yet it does not destroy the well recognized character of the baked product as standard white bread.  The present invention also relates to a milk substitute for use in bread which consists essentially of a dry blend of pea flour and whey.  Bread dough having the pea-whey milk substitute is not only characterized by reduced mixing and fermentation times, but also the resulting baked bread has been found to have a superior crust color and crumb structure.

Abstract: ABSTRACT OF THE DISCLOSURE            A thermal break in a metal frame for a door and/or window is provided by moulding and curing thermal barrier material, such as resin, in two parallel, laterally spaced, elongate gaps defined between respective pairs of confronting elongate surfaces of the inner and outer frame elements which when assembled form a box-section member.  The gaps are converted into respective mould cavities for the resin by the pressure of shoes against the elements adjacent the respective gaps to close one side thereof, the shoes being removed only after the resin has cured to leave the finished thermal break.  The shoes are carried on opposite walls of a laterally expansible tube which is inserted into the box-section and is expanded to press "non-stick" surfaces of the shoes against the respective gaps ready for the moulding and curing of resin therein, whilst maintaining the gap dimensions.  After curing of the resin, the tube is contracted laterally to disengage the shoes and is then withdrawn to leave the finished thermal break.

Abstract: High Efficiency Gettering in Silicon Through Localized Superheated Melt Formation Abstract A semiconductor wafer into which devices such as an integrated circuit is to be formed is gettered by regions in the wafer activated by a laser beam. The laser beam is directed onto the surface of the wafer opposite to that where the devices are to be formed.  The power input to the laser is controlled such that the surface temperature of the region of the semiconductor wafer where the laser beam is applied first reaches the melting point of the material, such as silicon, and the melting commences. Then the temperature in the melt rises above the melting temperature, but stays below the boiling temperature of the material of the wafer.  A super-heated melt is formed.  The result is that the solid-liquid interface moves deep into the material. The position of the melt is directly under the laser beam.  The solidified material is positioned behind the beam as the beam scans the wafer.  A depression is formed under the beam while the material rises behind the laser beam.  This depression effect of the laser beam causes the beam to penetrate relatively deeply into the material.  The superheated melt of this type has been found to be useful in the activation of internal gettering centers as opposed to crystal damage by a higher powered laser beam.  These internal gettering centers, which may be oxygen complexes or the like, then act as gettering sites for unwanted impurities during subsequent heat treatment of the semiconductor wafer.

Abstract: ABSTRACT A formwork board is made up of at least two formwork board parts fitting together, whilst the separating line between these two formwork board parts is defined by abutment webs, straps or the like which, in cross section, are located in an inclined position relative to the formwork skin of the form-work board and to the outer edge webs of these formwork board parts.  Prefer-ably, three formwork board parts fit together to form a rectangle.  The formwork board part whose abutment webs form an obtuse angle with the formwork skin can be removed first during the stripping of the forms, thus producing a corres-pondingly wide form-removing gap.  The removal of this first part of the formwork board is made easier by the shape resulting from the inclined arrange-ment of the abutment webs.  Thus, the forms can readily be removed even between two outgoing walls, in shafts or the like.

Abstract: ABSTRACT OF THE DISCLOSURE        The conventional vertical drive sawtooth is modified, during the camera setup mode, to halve the slope thereof for a given field time interval, or intervals, and to double the slope for the remaining field time interval. It follows that the speed of vertical scan is halved and doubled respectively, in the corresponding field time intervals.  In the interval of double scan speed, blooming occurs and twice the usual beam current is required to success-fully discharge the picture.  Thus when the beam set circuit is in operation as during the setup mode, the beam current is increased until the blooming existing in the double scan speed interval just subsides.  The beam current has then been set at 200% of typical beam level.
