Abstract: Abstract A ball locking mechanism for releasably locking a movable member is provided with a ball which is arranged in apertures of a stationary member and is pressed by a slide member into one of several apertures of the movable member thereby locking such member in position.  For unlocking the movable member, the slide member is moved until an aperture provided therein becomes coaxial with the other apertures.  The ball then slides out of the first-mentioned aperture.  The movable member can then be moved until a further similar aperture is coaxial with the aperture in the stationary member.  The tension applied by a spring on the slide member then slides the ball into this new aperture.

Abstract: TUBULAR SOLENOID              Abstract of the Disclosure Low cost tubular solenoids are formed with a drawn case in which the pole portion forming the base of the solenoid is defined as an integral inwardly extending part of the case.  A coil bobbin is formed by the injec-tion molding of plastic material and is provided with an integral wall which is positioned in abutting relation to the inside surface of the pole portion, thereby forming a stop surface for the solenoid plunger and effectively spacing the plunger from the base.  The plunger is guided on the internal surfaces of the bobbin and in one embodiment, a spun hollow sheet metal bushing is captured by the case in telescopic relation to the bobbin, and is formed with threads which receive thereon a sheet metal retaining nut.  In another embodiment of the invention, a washer is threaded onto an axial extension portion of the bobbin, and the open end of the case is crimped onto an annular groove formed on the washer.          In a further embodiment, the washer is injected molded in place on the bobbin.  Terminal leads are molded on the bobbin and extend through apertures formed in a bobbin extension elimating the need for the placement of coil lead-in wires.

Abstract: ABSTRACT         A laser control system using a resonant cavity of the type producing adjacent modes of opposite polarization and with mirrors mounted by a system having a non-zero thermal expansion coefficient.  A beam splitter plate in the output beam provides two low intensity beams which are passed through film polarizers to provide beams proportional to the intensities of oppositely polarized adjacent modes.  A detector is positioned in each low intensity beam and a differential amplifier is connected to the detectors.  The output of the differential amplifier controls a heating coil around the resonant cavity which in turn controls the mirror spacing by varying the temperature of the mounting system.  Thus, the radiation received at each detector is maintained equal and the adjacent modes stabilized.  A further polarizer  in the output path transmits the radiation at one of the modes.

Abstract: ABSTRACT:     An appliance comprises a digital programming device for forming a sequence of control signals.  When the device is switched on by way of the mains plug, an unpre-dictable switch-on phenomenon occurs and the program memory is liable to be addressed in a variety of locations.  There-fore, during a preparation routine the start conditions (initial conditions) are realized.  Furthermore, a multi-bit code is generated and stored in a volatile section of the memory.  The operative routine comprises a sub-routine which tests this code.  If the code is not correct, the prepara-tion routine has not been followed when the appliance was switched-on.  The operative routine is then interrupted and first the preparation routine is executed.  All further locations in the non-volatile memory section preferably refer to the preparation routine.
