Abstract: Method and apparatus for detecting the emission of radia­
tion from a sample.  
     The apparatus comprises a frame. Means are mounted on 
the frame for supporting the sample and for detecting radia­
tion. Means are also mounted on the frame for shielding the 
radiation detecting means from background radiation. The 
method comprises the steps of providing a radiation detector 
and a first shield for the radiation detector. The shield is opera­
tive to limit the sector in which radiation can be detected. A 
second shield is provided for minimizing background radiation 
that impinges on the detector so that the first and second 
shields define a testing zone and at least a portion of the sample 
to be tested is placed in the testing zone.

Abstract: Disclosed herein is an open-ended ratchet wrench 
which can turn a nut (30) in one direction in a conventional 
manner and which can have the open-ended jaws (14,24) expanded 
to allow the wrench to ratchet back around the nut. This 
is accomplished by providing a lower jaw member (14) pinned 
to the main body (12) which is held in a normal position by 
a pawl (16). When force is placed against the pawl, it 
rotates to allow the lower jaw member(14) to rotate to an 
expanded position. Both the lower jaw member(14) and the pawl 
(16) are biased to the normal position by springs. The lower 
jaw member is pinned to the main body by a cam (24) inserted 
into a cutout (36) in the main body.

Abstract: Verfahren zur biologischen Behandlung von Abwasser 
mit Hilfe einer Kaskaden-Tauchtropfkörper-Anlage  
     Die Patentanmeldung befaßt sich mit einem Verfahren 
zur biologischen Behandlung von Abwasser mit Hilfe 
einer auch für die Oxydation von Stickstoff-­
Verbindungen ausgelegten kaskadenartigen 
Tauchtropfkörper-Anlage.  
     Gemäß der Erfindung ist vorgesehen, daß die 
Fließrichtung des zu reinigenden Abwassers von Zeit 
zu Zeit umgekehrt wird.  
     Als wesentlicher Vorteil ergibt sich, daß die Vorzüge 
des längs-durchströmten Kaskaden-Tauchtropfkörper-­
Systems genutzt werden, ohne die aufgeführten 
Nachteile in Kauf nehmen zu müssen. Die Umkehr der 
Fließrichtung bewirkt, daß in allen Kassetten hohe 
Populations-Dichten stickstoff-oxydierender 
Bakterien erzielt werden. Bakterien, die sich während 
der einen Phase des Betriebes im Hungerzustand 
befinden, werden nach Änderung der Fließrichtung 
wieder ausreichend mit Substrat versorgt. Hohe 
Bakterien-Dichten auf allen Bewuchskörpern des 
Systems erlauben einerseits eine höhere 
Nitrifikationsleistung des Gesamtsystems und 
andererseits eine deutliche Verbesserung der 
Prozeß-Stabilität bei wechselnden 
Abwasserverhältnissen gegenüber der bekannten 
Verfahrensweise.

Patent EP-0272893-A3 (EP)
IPC: H04N5/44
Filed: 1987-12-18
Abstract: Display apparatus which includes a cathode ray tube. 
Electrical signals carrying information indicative of visual 
images are conveyed to an electrode in the tube and an electron 
beam is modulated in response to the signal and scans the screen 
in line and field directions to generate visual images. The line 
scan causes the beam to move alternately in the forward sweep 
(display) and flyback directions and the apparatus is arranged to 
cause the ratio of blanking period to display period to be greater 
than conventional values, i.e. at least 23.08%. Increasing 
blanking time and hence available flyback time over conventional 
values allows display improvement techniques, such as increasing 
field rate or number of lines per field, to be used without 
requiring, for example, line output transistors with higher 
voltage ratings.

Title: Method to automatically vary displayed object size with variations in window size
IPC: G06F3/048
Filed: 1988-12-20
Abstract: A method to maintain all of the information that is 
originally displayed in a window on the display screen in an 
interactive information handling system, as the size of the 
window is decreased. By selecting from a plurality of 
different character sets that are stored in the system, a 
character set is obtained which has the appropriate width 
and height attributes that allow the original text 
characters to be substituted for the corresponding text 
characters originally displayed. Since the selected 
character set contains proportionally smaller characters no 
information is lost because the size of the window was 
decreased.  
     The different character sets that are stored may be hardware 
implemented such as ROM character generators based on 
different sized character boxes or software generated 
character sets which are also based on different sized 
character sets. The type of font is important only in the 
context that some fonts are more readable as the size of the 
characters decrease than others. The method allows the 
operator to dynamically vary the window size after the 
initial window has been displayed in response to some 
predetermined action by the operator.  
     Any of the techniques suggested in the art for changing the 
window size would be appropriate. In the preferred 
embodiment of the method, the system includes a "mouse". 
Movement of the mouse in a generally horizontal direction 
with the button in the held position causes the horizontal 
window size to increase or decrease. The amount of decrease 
is calculated in real time by monitoring the movement of the 
mouse and cursor position. A table is stored in memory which 
lists all of the displayable character sets that are 
available. Each character set has a width attribute and a 
height attribute. A percentage decrease in width and height 
 
 
is stored in the table representing changes from the 
corresponding attributes of standard character set that is 
normally used to display information in the system. A new 
character set is selected from the table in accordance with 
the calculated percentage of decrease and the new character 
substituted in the text. If the user sizes the window below 
limits of readability or system capability for resolution, 
the window components are replaced with a graphic 
representation of the data or with icons. If the user 
decides to restore the size of the original, a 1-step key or 
mouse button sequence is available.
