Patent NO-147619-C (NO)
Inventor: TRESCH ERWIN
IPC: G08B17/107
Filed: 1979-12-28
Abstract: A smoke detector containing a radiation source operating in a pulsed mode and a scattered radiation receiver connected in a coincidence circuit. This circuit contains a counter which counts both the radiation pulses and the incoming scattered radiation pulses. With undisturbed operation this counter, following each radiation pulse, has an even numbered counter state. The appearance of an uneven numbered counter state is indicative of the presence of spurious pulses and leads to resetting of the counter to null, so that there is prevented attainment of a counter state adequate for tripping an alarm signal. On the other hand, with the presence of a predetermined even numbered counter state there is triggered an alarm. Such smoke detector is almost immune to spurious pulses and does not tend to trigger faulty alarm signals.

Title: Expert system apparatus and methods
Inventor: BOLLING RICHARD W
IPC: G06N5/02
Filed: 1990-03-19
Granted: 1999-11-30
Abstract: A definition-based expert system and expert system shell.      The expert system shell creates a knowledge base consisting of terms and their definitions, the definitions making up a hierarchy of definitions in which each definition depends only on terms defined at lower levels in the hierarchy or on term-independent values. Expert responses are obtained from the system by evaluating the terms. When a term is evaluated, all of the term-independent values and the values of all of the terms in its definition are obtained. The definitions include operators specifying operations which are to be performed when the defined term is evaluated. The operators include causing other systems operable in the digital computer system in which the expert system is operating to operate. The definitions further include table operators. Base table operators define terms representing tables and columns in the tables and permit loading of the tables. Query table operators define terms representing tables defined from base tables or other query tables.      Column operators permit operations involving all of the fields of a column. The expert system is further able to respond to "don't know" values in a fashion which depends on the significance of the "don't know" value for the definition of the term.

Title: Energy-conserving injection molding machine
Inventor: HERTZER RONALD A
IPC: B29C45/02
Filed: 1991-01-04
Granted: 1995-07-18
Abstract: A  hydraulic   injection  molding  machine incorporates a pump driven by a variable speed motor preferably of the brushless  DC type.   The machine controller outputs driving signals to adjust the speed of the motor so that the flow delivered by the pump substantially  matches  the hydraulic  demand  imposed during each phase of the machine operating cycle.  The pump is preferably a variable displacement type and is connected  to  a  fast  responding  pump  control  for selectively carrying out pressure compensation or flow compensation.  The values of the motor driving signals are calculated so that the motor/pump combination is operated at or near maximum efficiency except when the pump control varies the displacement of the pump to effect  pressure  or  flow  compensation.   Hydraulic transient response is further improved by connecting the output of the pump to an accumulator by way of a check valve.
