Abstract: ABSTRACT OF THE DISCLOSURE         Two  computers are controlled each by timing periods produced by its own clock and work therefore asynchronously.          Each computer is provided with a pulse treatment circuit which breaks, owing to a break signal, the computer work during the following timing period.  A buffer memory is used in order to transfer information from the first to the second of the computers.  The asynchronism causes a risk that the buffer memory becomes totally occupied and unoccupied, respective-ly.  The risk is eliminated by means of an address and break signal generator which generates addresses to control writing and reading of the buffer-memory and generates break signals which are sent to the pulse treatment circuit of the first and second computer in order to inhibit that information is sent to and received from the buffer memory, respectively.  The writing and reading addresses are generated by means of a first and  a second circulating address counter stepped by the pulse treatment circuit of the first and second computer, respectively.          The break signals are generated by means of a comparator connected to the two address counters.  The timing periods have parts during which the computer components work unreliably due to their reaction times.  A reliability device compares therefore the phases of the timing periods produced by the two computer clocks in order to allow only break singals which are generated owing to the comparison of addresses obtained in period parts during which both address counters are reliable.

Abstract: ABSTRACT OF THE DISCLOSURE   A vertical aperture correction circuit is disclosed, wherein undesirable amplitude changes of luminance signals of alternate lines are cancelled.   First of all, luminance signals of adjacent two lines are added for cancelling the undesirable amplitude changes in the main luminance signal.  Further a difference between the luminance signals of adjacent two lines is squared for cancelling the undesirable amplitude changes in a vertical detail signal.  By mixing the corrected main luminance signal and the vertical detail signal, a vertical aperture corrected video signal is obtained without the undesirable amplitude changes between lines.

Abstract: TERMINAL STRUCTURE FOR OUTDOOR LUMINAIRE            ABSTRACT OF THE DISCLOSURE:         A weatherproof terminal or junction box structure for a luminaire adapted for connection by a mast to a building or pole.  The structure enables access to the terminal or junction box area for wiring and inspection without disassembly of the mounting of the luminaire to the mast and without the necessity of disassembling the luminaire itself.  The mast telescopes within a channel receiver of the luminaire housing for mounting purposes.  The mast is slotted at its entry end, the slot be-ing encompassed within an access opening which may be covered by a wire way cover.  Removal of the cover exposes the wiring for connection and inspection.  With the cover in place, recessed within the receiver, the connection of mast to lumin-aire produces a weatherproof mounting. A second embodiment omits the need for the cover by normally setting the entry end slot rotated out of registration with the channel opening.  Access to the slot may be had by rotating the luminaire about the axis of the channel receiver.

Abstract: FROSTPROOF BACKFLOW PREVENTER                 ABSTRACT OF THE DISCLOSURE          A backflow preventer in a fluid conduit permits flow from the inlet to the outlet of the preventer when the inlet is pressurized and prevents reverse flow upon termination of flow through the preventer.  An apertured diaphragm between the inlet and outlet closes a valve seat between the outlet and a vent passage when the inlet is rela-tively pressurized.  A check member upstream of the diaphragm closes the diaphragm aperture if the outlet is relatively pressurized and maintains the diaphragm aperture closed upon pressurization of the inlet until after closing of the vent valve seat.  A second vent communicates with the interior of the preventer and is closed  by a portion of the diaphragm upon pressurization of the interior.  A relief port in the chamber includes a temperature responsive element that opens the relief port once ambient temperature reaches a preselected level.  The inlet includes an internally threaded sleeve within the housing that may be secured to an externally threaded fluid hydrant.  The sleeve allows the preventer to be attached to a hydrant, but prevents its removal after a key in the sleeve is removed.

Abstract: ABSTRACT     An automatic  electric cigar lighter comprising a holder device presenting an outwardly facing socket, and a unique ignitor plug receivable in the socket. Disposed at the inner end of the plug is a heating element which is electrically connected in circuit with a heat-responsive switch that is also carried by the plug.  The socket in addition to its grounding circuit has a "hot" contact which is engageable with a cooperable contact  of the plug to effect the circuit through the heating element.  The plug comprises a manually operable part by which the heat-responsive switch can be closed, thereby to complete the heating circuit through the element.  A bimetallic member is also carried by the plug, engageable with one of the switch parts and normally lying in a circuit-opening position wherein it maintains the switch parts separated, and from which it can be shifted to a closed-circuit position.  In both positions it can receive radiant heat from the heating element, and when in the closed-circuit position it can snap to the circuit opening position to effect opening of the lighter circuit and de-energization of the heat-ing element after useful incandescence has been reached.  Cen-tral portions of the bimetallic member are free and not attached anywhere to any parts of the plug, but instead are merely dis-posed in close proximity to one of the switch parts, such that the member can quickly effect opening of the switch without need for mechanical securement of its central portions.  The advan-tage of this construction over the devices of the prior art is that there are eliminated problems previously associated with the usual fastenings made to a bimetallic member, such as securing a contact to the member, etc.  Improved reliability and operation, together with faster operation, are thus realized.

Abstract: Abstract In a method for continuous heat treatment of separated elongated metallic material said material is conveyed stepwise through a single furnace chamber. Said furnace chamber comprises a heating section and an adjacent holding section. In the heating section the material is heated up to a treating temperature and in the holding section the material is held at the treating tem-perature both in an atmosphere of forced circulation of hot gas common to both furnace sections. The  temperature  of the circulated hot gas is automaticcaly feedback-controlled at the location of the transition between the heating section and the holding section, the hot gas being set into forced motion in a single circulating zone and being heated up in a single heating zone with respect to the direction of passage of the material. Additionally the temperature of the material may be measured at the said location of the transition between the heating sec-tion and the holding section and the conveying movement of the material may  be interrupted for the time necessary to heat up the material to the treating or holding temperature.

Abstract: ABSTRACT The alcohol concentration in the blood is determined by analysing exhaled air.  Air is exhaled through a tube past a sensor in an alcohol measuring device.  Measurements are conveyed to an indicating device only when they are higher than all previous measurements during the test.  A flow measuring device measures the volumetric flow of exhaled air and terminates the test when a preset flow has passed, when the indicating device displays the highest alcohol measurement so far recorded.  The preset flow is selected to ensure that the test subject takes at least one deep breath during the test so that the results can not be falsified by deliberate shallow breathing.
