Title: Automatic focusing system of an observing means for inspecting an object
Inventor: IKEDA HIROSHI
IPC: G01N21/956
Filed: 1987-10-06
Granted: 1990-10-16
Abstract: ABSTRACT    Focussing of a TV camera for visually inspecting an object is executed while the object is being removed to line up the TV camera with the next inspecting point on the object by using a cal-culated distance from the TV camera to the next inspecting point without measuring the actual distance.  The distance to the next inspecting point is calculated from a plane equation of one of several triangular planes formed over the object by connecting reference points previously designated on the object.  The plane equations are calculated before executing the inspection, by using distances, actually measured by a distance measuring means, from the TV camera to the reference points.  The invention reduces the time necessary to inspect the object which is important in the case of large printed wiring boards.

Title: Chain for supporting flexible conduits with curvilinear path
Inventor: MAURI GIOVANNI
IPC: F16G13/16
Filed: 1987-12-30
Granted: 1991-09-17
Abstract: ABSTRACT A chain with curvilinear path for supporting flexible conduits is described here, of the type in which the links are constituted by two sides each having a male connection at one end and a female connection at the other, which can be connected male to female to the adjacent link by means of an appropriate dowel thus permitting reciprocal articulation, said sides being connected to one another by means of a root and a detachable upper link stud which form the support surface for the flexible conduits carried by the chain, characterised by the fact that the said links are curvilinear, thus permitting articulated movement of each link in order to follow the traditional curve-during the back and forth movement but also to take on a skewed attitude during the course of the curve in order to be able to follow the rotational movements of the rotating equipment which must be supplied by the flexible conduits. Thus this chain can also be applied to machine tools and robots which carry out reciprocal rotary movements.

Abstract: Abstract An electronically operated pistol (10) has a frame (32) upon which is mounted a barrel (36) and a shell (12) which encloses virtually all moving parts.  The pistol has a trigger (14) which, when pulled, moves a front section (56) of a trigger bar (48) carrying a magnet (80) of a Hall effect switch.  The trigger bar has a rear section (58) connected to a solenoid (114) which is actuated by a current amplifier (104) in a control circuit (124) which includes the Hall effect switch.  Both sections of the trigger bar are independently axially movable but are so connected as to be pivotable about the trigger in unison to perform a disconnect function in association with a sear (78).  A switch (104) in the control circuit mounted on the barrel senses the presence of a chambered cartridge (92).  The control circuit includes a first light emitting diode (26) which illuminates when a round is chambered and a second light emitting diode (28) which illuminates when control circuit power is low.  Voltage comparators (132,130) in the circuit signal logic elements (136,146,148,140) when power is low or the second light emitting diode fails to properly illuminate in order to prevent actuation of the solenoid.  An electronic failure, which causes current to be constantly directed through the solenoid, is sensed by a voltage comparator (152) which causes an oscillator (154) to rapidly flash the second light emitting diode.

Title: Multi-stage rocket motor nozzle throat
Inventor: GRASER WARREN L
IPC: F02K9/26
Filed: 1988-03-30
Granted: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE    The invention is concerned with reducing the effect of a progressive surface area versus web thickness rela-tionship in a rocket motor and is particularly useful with center perforate propellant grains where the chamber pressure versus time history is generally progressive.  In a very short action time rocket motor, it is desirable to keep the chamber pressure as close as practical to the peak during the entire burn to increase the propellant burn rate.  The multiple-stage throat makes this possible in a motor that uses the cost effec-tive center perforate propellant grain design and operates by allowing a first stage throat to erode at a predictable rate while the area of the propellant burning surface is increasing.  The motor initial Kn (propellant surface area divided by nozzle area) is raised by using a relatively small initial size for the first stage throat and as a result the rocket motor reaches peak chamber pressure quickly.  With the erosion of the first stage matching the increasing propellant surface area the chamber pressure remains nearly constant.  Near the end of the burn the first stage throat erodes out to the diameter of a non-eroding second stage throat which then becomes the controlling throat.
