Abstract: ABSTRACT OF THE DISCLOSURE           An improved, self-contained, remotely controlled color television system is disclosed.  The system utilizes a small head mounted television camera which is adapted to transmit a picture of the operations carried on by the wearer of the camera to be remotely viewed and/or recorded by a third party.  The focusing and aiming of the camera is re-motely controlled from a console equipped with controls and a television monitor.  An illumination system is provided which utilizes a dual beam, the convergence and elevation of which is controlled by the wearer.  The illumination is fixed to the head mounting so as to follow the head movements of the wearer.  The dual beam of the illumination system enables the area desired to be illuminated by the wearer to be so illuminated virtually without shadows and without interference to his field of view.  The video image reproduced by the system is of a high quality which makes it quite useful for teaching and demonstrating such things as delicate surgical procedures of the type often found in dental, abdominal, cardiovascular and neurosurgery.  Control of the illumination system by the wearer enables him to work without distraction caused by re-mote control of the illumination system.  A second stationary mounted camera may be added to this system to provide addition-al coverage.

Abstract: MONITORING CIRCUITRY FOR A SAID CONTROL SYSTEM            Abstract:   A skid control system serves to control the opera-tion of a braking system for applying braking forces to a pair of spaced apart, independently rotatable vehicle wheels.  The system employs a brake control device which responds to a skid signal for controlling the braking system to release the braking forces on the wheels.  Wheel speed signals are provided by sensor circuitry and are representative of the wheel speeds of the first and second wheels.  Logic circuitry utilizes the wheel speed signals to determine an incipient said condition of at least one of the wheels and, in dependence upon the determina-tion, provides a skid signal.  Monitoring circuitry is provided for use with such a skid control system for inhibiting the operation  of  the system.   The wheel speed sensing cir-cuits are monitored for sensor continuity and a control signal is provided when an open circuit condition is detected.  This control signal is employed to disable the skid control system.          Monitoring circuitry is also provided for monitoring the brake control, such as a valve solenoid, and for disabling the system when a determination is made of either an open or shorted solenoid coil.  Monitoring circuitry is also provided for moni-toring the time duration that a skid signal is provided by the skid signal logic circuitry and disabling the skid control system when the time duration of the skid signal is excessive.

Abstract: ABSTRACT         A square puzzle consisting of twelve  polygons.          The shapes and sizes of these polygons are based on the division of a square into thirty-six right isosceles triangles.          The length of the hypotenuse of those triangles is one third of the length of a side of the square.  Two of the 12 pieces are such right isosceles triangles.  The ten other pieces represent all the configurations which can be formed in the above mentioned division of the square by the joining of two, three or four such right isosceles triangles.  The puzzle can be assembled into the square in many different ways and this exhibits long-lasting attraction to users.

Abstract: METHOD OF CUTTING SOLIDS OF REVOLUTION BY A ROTARY TOOL HAVING CIRCULAR CUTTING LIP, AND A ROTARY           TOOL FOR CARRYING SAME INTO EFFECT                  Abstract of the Disclosure The herein-proposed method of cutting solids of re-volution by a rotary tool having circular cutting lip resides in that the tool is imparted feed motion, while its rotation results from the interaction of said tool with the rotating workpiece being machined. Prior to bringing the tool in contact with the surface being ma-chined the tool is imparted a position rotation at a speed differing by not more than 20 per cent from the tool working speed in the same direction as the tool working motion. The rotary tool for carrying said method into effect is shaped as a solid of resolution having a circular cutting lip and held on a spindle provided with a through centre bore for the stream of coolant to feed therethrough, the screw-type wind turbine being provided in said spindle bore.

Abstract: ABSTRACT OF THE DISCLOSURE     A tubular chamber is divided by a rigid annular par-tition into two sections. Each section comprises a re-silient membrane installed co-axially with the chamber shell with a certain gap relative to the shell to form a cavity communicating with a gas medium source. This ca-vity accommodates a stationary perforated rigid member installed co-axially with the membrane and the chamber wall to bear the membrane in its extreme expanded state, when no gas medium is supplied into the cavity. When the gas medium is delivered from the source into the cavity, the membranes contract and expand alternately, causing the fluid to move and agitate. An installation for treat-ment of loose materials is proposed, which is constructed with the use of these fluid-stirring devices.

Abstract: ABSTRACT OF THE DISCLOSURE       A target game can be constructed utilizing a support member and a transparent housing or cover mounted on the support member so as to enclose an elongated, enlarged area.          A target is movably mounted on a guide rail within this area so as to be capable of being moved between the ends of a path.          A spring is located on the support member for moving the target from adjacent to one end of the path to adjacent to the other end.  An escapement structure consisting of parts mounted on the support and on the target controls such movement so that the target member only moves incrementally each time it is engaged by a projectile.  A shooting structure is pivotally mounted on the support so as to be accessible from the exterior of the housing.  This shooting structure includes a hollow tube within which there is carried a plunger capable of being manipulated so as to shoot projectiles.  A feed passage leads into this tube for conveying projectiles into the interior of the tube when the shooting structure is pivoted so that this feed passage is aligned with a projectile feed channel located generally between the support member and the housing .

Abstract: Abstract of the Disclosure A disc valve having a valve housing with a conduit therethrough and a seal ring mounted to the housing.  A disc can be pivoted about a pivot axis that is offset from the main valve axis and perpendicular thereto between an open position and a closed position in which a seating surface of the disc contacts a sealing surface of the seal ring In a sealing plane that is perpendicular to the valve axis.  The seating surface of the disc is a conically shaped surface that is concentric with the valve axis when the disc is in the closed position.  At least a portion of the sealing surface of the seal ring at the intersection between the sealing surface and the sealing plane has the same conical shape.  The seal ring can be deflected by moving the disc beyond the closed position to thereby increase the sealing pressure between them.  The seal ring can be aligned with the seating surface of the disc by initially floatingly mounting the ring to the housing, then closing the disc to center the seal ring,  and thereafter locking the seal ring to the housing in the centered position. Opposing faces of the disc are slanted relative to the axis of the conically shaped seating surface.

Abstract: ABSTRACT:              An X-ray examining device, comprising an X-ray image intensifier and a television pick-up tube and monitor involves film recording where film material can be arranged directly against the exit window of an X-ray image intensifier tube.  As a result the customary, pivotable light distributor need not be included in the basic optical system between the X-ray image intensifier tube and the television pick-up tube, to that the basic optical system can be optimized to form a compact system offering optimum image transfer.  Because the film recordings are made directly behind the exit window, a substantially lower radiation dose and less film mater-ial are required.
