IPC: G06F3/0481
Filed: 1991-10-17
Abstract: ABSTRACT OF THE DISCLOSURE    In a data processing system employed for simulation, a simulation program (24) produces simulation results (26), while a pre-compiler (18) used to prepare the simulation program (24) generates cause and effect lists (22).  The cause and effect lists (22) and simulation results (26) are organized in data groups associated with the various variables in the model.  A presentation module (28) operates a display (16) so as to display variable names (37) that represent the data groups and icons (32, 34, 36, 38, 40, 42, and 44) that represent operations that can be performed on the data groups.

Title: Scanning optical microscope
Inventor: WALKER JOHN G
IPC: G02B21/00
Filed: 1990-06-05
Abstract: The invention improves the resolution in a scanning confocal microscope by performing optical signal processing prior to detection. Such processing is achieved by an element (7, 39, 42) having either or both phase and amplitude weighting. The microscope may be a transmission, reflection, or fluorescent microscope. In a transmission microscope a laser (1) illuminates a small area of a sample (3). Light from this small area is focussed onto an optical processing element (7). Output from the element (7) is detected by a detector (11) via a pin hole (9) in a stop plate (10). Phase weighting of the element (7) may be formed by a rectangular grating (15), and amplitude weighting formed by a sinusoidal variation in absorption. One optical weighting function m(x, y) is cos (2.pi.Nx/.lambda.).cos(2.pi.Ny/.lambda.), where N is the numerical aperture of lenses (2, 6) and .lambda. is wavelength. An alternative optical weighting function m(x, y) is sign (cos(2.pi.Nx/.lambda.)).sign (cos(2.pi.Ny/.lambda.)).

IPC: E03D3/08
Filed: 1992-01-15
Abstract: An on demand, non-contact sensor controlled flush valve actuation system  includes a flush valve between a water supply and a plumbing fixture.   An actuator for the flush  valve  includes  a  moveable  piston  in  fluid communication with a control water inlet, with a control water conduit carrying water from the flush valve through a  solenoid  operated  control  valve  to  the actuator assembly.  A radiation sensing/detecting unit generates a first control signal in response to the return reflection of infrared radiation.  A timer receives the first control signal  and,  in  response  thereto,  generates  a  second control signal of a predetermined duration which activates the solenoid.   When the solenoid is activated, a portion of the pressurized supply water flows into the actuator assembly  and against a piston therein, with the piston moving to operate a trip mechanism for the flush valve.

Patent CA-2060346-A1 (CA)
Title: Pallet containers
Inventor: SCHUETZ UDO
IPC: B65D77/06
Filed: 1992-03-13
Abstract: The palette-container (101) for liquids has an exchangeable plastic inner container (102), an outer shell (106) of lattice work and a palette (109) which is constructed as a bottom tray (110) and receives the bottom (111) of the inner container with positive fit, said bottom being constructed as a drainage bottom and having a filling nozzle (103) and an emptying nozzle (115) with a removal tap (105). Reinforcing beads (118a, 118b) are moulded into the bottom tray (110) which is adapted to the inclination of the drainage bottom (111), the bases (119) of the said reinforcing beads lying in a common horizontal plane (120-120). The flat bottom tray (110) has an outer support edge (117) extending downwards and is riveted or welded to a flat sub-base (121) or a sheet metal underframe in the region of the reinforcing beads (118a, 118b) and of the support edge (117) to form a hollow bottom with closed and/or open chambers (123) and a peripheral, outer, hollow support collar (124). 
<??>Due to the use of a flat bottom tray which receives the plastic inner container and has a flat sub-base or sheet metal underframe having hollow chambers and an outer, peripheral, hollow support collar, the palette is distinguished by a good damping capability and a high rigidity both in the case of oscillation loading due to gush oscillations of the liquid product in the container and due to oscillations transmitted by the transport vehicle and in the case of jolting and impact loading.

Abstract: A programmable controller is customized for a specific application by a function card inserted into a socket of a processor module on the controller.  The function card can perform one or more tasks and may be used with different types of programmable controllers.  Before the card can be used by a given programmable controller an initialization procedure must be performed to determine if the processor module and the card are compatible.  As part of this procedure information about the operation of the given programmable controller is sent to the card.  The card also contains functional information for each of its tasks the card provides.  The functional information is sent to the processor module during the initialization procedure to enable the module to utilize the card.

Title: Method for removing, condensing and collecting propellants from foam materials and other materials for which the method is suitable in an environmentally friendly manner
Inventor: VOERS LAU O
IPC: C09K3/00
Filed: 1990-08-17
Abstract: A method for removing, condensing and collecting propellants, e.g. chlorofluoro-carbons (CFCs) in an environmentally friendly manner from foam materials, e.g. insulant materials from old (discarded) refrigerators, district heating tubes and other materials for which the method is suitable. The method is based on the fact that the decomposition of the foam materials and accordingly the liberation of the propellant in the foam takes place in a liquid medium, e.g. water. In case the temperature of the liquid medium is equal to or above the temperature corresponding to the boiling point of the propellant at the actual pressure, the propellant is liberated from the foam as a gas. The propellant gases are conducted through one or several liquid media, e.g. water and/or one or several ''cold traps'' in which the temperature is below the temperature corresponding to the boiling point of the propellant gases at the actual pressure which causes that the propellant condenses. In case the temperature of the liquid medium is below the temperature corresponding to the boiling point of the propellant at the actual pressure, immediately upon liberation the propellant will condense when entering into contact with the liquid medium and be located in the process container according to the density of the materials. The condensed propellant and the non-condensed gases are optionally conducted to a succeeding treatment.
