Title: Three dimensional graphic interface
IPC: G06F3/048
Filed: 1989-07-25
Abstract: A comprehensive imaging effect is employed with respect 
to all components (32,34,40-54), and elements of those 
components, appearing in a graphic interface (30) to 
present a cohesive three-dimensional visual metaphor to 
a computer user. The approach that is employed to achieve 
the imaging effect basically involves the use of at 
least three different colors, e.g. three different shades 
of a color, to represent highlighting and shading along 
opposite edges of each component. Menu boxes (40) and 
the like are also represented in this manner to provide 
a visual representation of an integrated, three-dimen­
sional structure. Shadows are displayed in a manner 
which conforms to the topology of illustrated components 
upon which they are cast, to reinforce the three-dimen­
sional appearance of the display.

Title: Speed governor for small engines
IPC: F02D11/10
Filed: 1989-09-18
Abstract: A speed regulating governor system (10) is 
disclosed for a small internal combustion engine 
having a throttle valve (12) the position of which 
affects the speed of the engine, wherein the governor 
system includes a mechanical proportional controller 
(42) and an electromechanical integral controller 
(60). The throttle valve is mechanically linked to 
and controlled by a governor lever (24) that is acted 
upon by opposing forces provided by a mechanical 
speed selector (34) and a centrifugal flyweight 
apparatus (42) which measures the engine speed. 
Additionally, a solenoid actuator (52) is operably 
connected to the governor lever to apply a force 
thereto in response to a control signal (62) 
generated by an electronic integral controller (60). 
The control signal is proportional to the time 
integral of the difference between a desired 
electrical speed input (126, 128) and the actual 
speed of the engine measured by an electrical signal 
(66) generated by an alternator driven by the engine.

Title: Passive data collection system for market research data
IPC: H04L12/423
Filed: 1989-02-28
Abstract: A passive data monitor and collection apparatus, 
and associated method, for obtaining market research data 
from an automated checkout system of a retail 
establishment. The apparatus positively monitors all the 
communications on a communications network between a 
plurality of point-of-sale terminals in a store and the 
store controller controlling the terminals. The store 
communications are converted from a phase encoded 
protocol into a standard RS 232 protocol which is then 
assembled into SDLC frames by a processor. The SDLC 
frames are separated on the basis of a control field 
format before being parsed by terminal addresses to form 
separate transactions on a list. The transaction list is 
produced by a real time monitor routine which builds the 
list from the asynchronous frame received from each of 
the store loops. The transactions on the list are 
handled in the background of the processing by a parsing 
routine which assembles the transactions into data files 
relating to the purchases by panelists and data files 
relating to the purchases by all customers. In a 
preferred embodiment, a host processor polls monitoring 
apparatus at a multiplicity of stores and has transferred 
to it the market research data files stored for the 
retail respective establishments.

Title: Power amplifying assembly
IPC: H04B7/185
Filed: 1989-07-14
Abstract: A power amplifying assembly has input ports (1 to 16) and 
output ports (1a to 16a) connected by a network (18) of 
balanced amplifier devices (17) which operate to couple the input 
ports to the output ports so that any amplification of a signal 
received at one of the input ports is shared by all the amplifier 
devices (17). This allows the total available amplification power 
to be used by any one or a combination of the output ports (1a 
to 16a) making the assembly particularly useful in a 
communications satellite with an antenna arrangement supplying 
signals to the input ports.
Patent EP-0356059-A3 (EP)
Title: Process for doping crystals of wide band gap semiconductors
IPC: H01L21/365
Filed: 1989-08-07
Abstract: Non-equilibrium impurity incorporation is used 
to dope hard-to-dope crystals of wide band gap semicon­
ductors, such as zinc selenide and zinc telluride. This 
involves incorporating into the crystal a compensating 
pair of primary and secondary dopants, thereby to increase 
the solubility of either dopant alone in the crystal. 
Thereafter, the secondary more mobile dopant is removed 
preferentially, leaving the primary dopant predominant. 
This technique is used to dope zinc selenide p-type by the 
use of nitrogen as the primary dopant and lithium as the 
secondary dopant. Alternatively, the technique may use 
nitrogen as the primary dopant and the hydrogen as the 
secondary dopant to obtain low resistivity p-type zinc 
selenide.

Patent EP-0376586-A3 (EP)
IPC: B29C65/20
Filed: 1989-12-19
Abstract: The invention relates to equipment to control the 
movement of members towards each other. In the jointing of a 
plastics pipe to the end of an immovable, already laid pipe 
length, there is a known difficulty in effecting equal 
trimming of the end of the pipe length and the end of the 
plastics pipe to be joined to that pipe length, and an equally 
known difficulty of applying the ends of the pipe length and 
pipe to a heater plate and to the same degree. This has 
frequently led to imperfect trimming and the creation of beads 
of different sizes, and which leads directly to the creation 
of a poor butt weld between the pipes. The object of the 
invention is to eliminate these problems in simple and cost-­
effective manner, which object is met by a construction 
comprising a central support (1), a lever (2) pivotally 
secured to said support (1), said lever (2) extending to equal 
degree to opposite sides of its pivotal connection to the 
support (1), links (3) pivotally connected to each end of said 
lever, with each link (3) extending to and being pivotally 
secured to a respective member (4, 5).

Title: Improved liquid scintillation measurement with active guard shield
IPC: G01T1/202
Filed: 1990-05-21
Abstract: A low-level liquid scintillation measurement system for 
counting sample optical events resulting from the radioactive 
decay of a constituent of a sample to be measured while 
reducing the counting of background optical events which are 
optical events produced by background radiation and which 
create electrical pulses other than pulses representing a 
sample optical event. This system includes detection means 
located adjacent the sample for detecting optical events and 
for converting optical events into electrical pulses, 
coincidence sensing means for receiving the electrical pulses 
from the detection means and producing a trigger pulse when 
the electrical pulses from the detection means coincide with 
each other, burst detection means for receiving the trigger 
pulses from the coincidence sensing means and the electrical 
pulses from the detection means for determining the number of 
electrical pulses present in a selected interval following 
each of the trigger pulses, evaluation means connected to the 
burst detection means for determining, in response to the 
number of pulses detected in the selected interval, the 
extent to which the optical event represented by the 
corresponding trigger pulse should be treated as a sample 
optical event or a background event, and an active guard 
shield arrangement comprising an auxiliary scintillator 
optically coupled to the detection means. The shield is 
adapted to be excited by background radiation and to 
effectively increase the number of electrical pulses present 
 
 
in the selected interval following a trigger pulse generated 
as a result of the coincident pulses produced due to the 
background radiation. The auxiliary scintillator is a glass 
comprising oxides of lithium, magnesium, silicon and cerium.

Abstract: In a compression release engine brake (10), 
electrically controlled mechanisms (50) are provided to 
partly selectively control the positions or motions of 
the engine brake slave pistons (70) which periodically open 
the exhaust valves (140) in the associated internal 
combustion engine (100) when engine braking is desired. The 
electrically controlled mechanisms (50) can be used for such 
purposes as controlling the "lash" of the engine brake 
or controlling the timing and duration of exhaust valve 
openings. Because these mechanisms are electrically 
controlled, they can be made to operate substantially 
instantaneously.
