Abstract: ABSTRACT OF THE DISCLOSURE     An ultrasound diagnostic apparatus includes a linear array of piezoelectric transducers or plates with a width-to-thickness ratio of less than 0.8 and a control circuit which includes a transmitter and a receiver.          The transmitter comprises a plurality of transmitting channels each including a local oscillator for generating an ultrasonic pulse in response to a clock signal.  The plurality of such ultrasonic pulses are applied through a switching network to a selected group of successively arranged piezoelectric transducers to transmit a beam of ultrasonic energy into a human body.  Each of the ultrasonic pulses is phase shifted and amplitude modulated with respect to the ultrasonic pulses of the other transmitting channels to provide phase and amplitude taper which results in a narrow width beam through the depth of the body.  The ultrasonic energy returned from discontinuities between different tissues is detected by the activated transducers and applied through the switching network to the receiver in which each of the return signals is phase shifted and amplitude modulated with respect to the other signals to provide an output signal which is displayed on a cathode ray tube screen.

Abstract: ABSTRACT OF THE DISCLOSURE      In labelling apparatus for precision application of labels to continuously conveyed articles, labels are applied which have a pressure-sensitive adhesive backing releasably carried by a web.  To provide precision in application, the leading portion of the label next to be applied is sensed and is separated from the web.  A control device, on receiving a sensed label signal, determines the extent to which the leading portion of separated label extends from the web preparatory to article application.  The control device resumes web movement to marry label speed with conveyed article speed in applying label to desired article location.

Abstract: ABSTRACT         The present invention relates to a safety belt adapted to be worn by a person for preventing the fall of such person on a ladder or when ascending or descending the ladder.  The present novel safety belt allows the user of the belt to alternately reach to the left or right of the ladder without adjusting the length of the belt during use and further allow the person using such a belt to remain securely held to the ladder.  The safety belt comprises a first belt member for fitting around the waist of a person.  A second belt member is provided which is adapted to be secured to a ladder and terminates in a first free end and a second free end.  The second belt is slidably secured to the first belt between the first free end and the second free end.          Ladder rung engaging members extend from each of the free ends of the second belt whereby when the safety belt is worn and in use by a person on a ladder and secured to a ladder through the ladder engaging members, a person can alternately reach to the left or right of the ladder and slidably move the first belt towards either of the free ends without adjusting the length of the second belt and remain securely held to the ladder.  The second belt may be adjustable in length.  This may be conveniently accomplished by providing a second belt that extends longitudi-nally to a buckle having a first opening and a second opening separated by a cross-bar and through the second opening and then in a looped configuration back to the cross-bar where it is secured.  The looped configuration comprises one of the ends of the second belt.  The ladder securing member may comprise a looped substantially rigid device lying in a first plane through which the second belt passes and is secured.  The looped member extends into a hook lying in a second plane substantially normal to the first plane.

Abstract: ABSTRACT   A PROCESS AND A PLANT FOR PREPARING A GAS RICH AN METHANE             The invention relates to an improved catalytic methanation process wherein a feed gas containing predominantly hydrogen and being rich in carbon oxides (CO and/or CO2) is divided into two part streams of which the first is methanated partially in an adiabatic methanation reactor by a methanation catalyst whereafter the effluent from the adiabatic methanation reactor is united after cooling with the second feed gas part stream and the thus-combined stream is methanated in a cooled methanation reactor by a methanation catalyst, preferably the same as that used in the adiabatic methanation reactor.  It is possible, but not always necessary, to recycle part of the recycle gas to the adiabatic methanation reactor to keep the temperature therein at a moderate level. The process is useful in connection with transport of energy from a nuclear reactor. It is advantageous because it can be operated to produce superheated steam, for use, e.g. for producing electricity, in connection with the cooling of the effluent from the adiabatic reactor, whereby energy losses can be reduced to a very low level; and because the amount of recycle gas is reduced, possibly to nil, whereby energy is saved.

Abstract: ABSTRACT The invention relates to equipment having a digital display, for use in measuring reaction time.  This equipment is suitable both for research and for routine testing procedures.  The equipment includes a stimulus-transmitting device which permits the application of two different light stimuli, two acoustical stimuli, the application of a white noise or a covering stimulus played from a tape recorder at the same time.  The equipment indicates whether a response took place with the right hand and/or foot.  It displays the occurance of a faulty reaction and also measures the reaction time in such case.  It is possible to couple to the equipment a special light-stimulus transmitter by means of which operational conditions may be simulated in a laboratory and the two cerebral hemispheres may be stimulated independently of each other.

Abstract: AUTOMATIC CHIMNEY CAP                  ABSTRACT OF THE DISCLOSURE      A chimney cap for closing and venting, selectively, the upper end of the chimney is manually controlled by means of chains or the like from a combustion area, particularly a fireplace, through counterweights and pulleys.  Automatic con-trol is determined by a smoke, heat, or incipient fire detector that will operate a hold relay to produce a signal split be-tween a reset timer and double-throw, double-pull switch that is in turn operated by the position of the cap to operate a revers-ible motor for movement of the cap to its upper vented position upon the detection of combustion products within the chimney. Movement of the cap to its upper position will shield the detector and other electronics from combustion products, and after a timed period, the reset timer will actuate the motor to move the cap to its closed position where it will remain unless the detector again detects the presence of combustion products.
