Abstract: LOCK MECHANISM FOR PRESS SHUTHEIGHT ADJUSTMENT                 ABSTRACT OF THE DISCLOSURE    A lock mechanism for shutheight adjustment in a press having a frame with a crown and bed, a slide mounted for reciprocation toward and away from the bed, and a drive mechanism comprising one or more crankshaft driven connection screws for reciprocating the slide.  The shutheight for the press is adjusted by means of a pair of internally threaded nuts on the threaded end portion of each of the connection screws, the nuts being connected to and carrying the slide.  The nuts are keyed together so that they rotate in unison and are rotated by means of a worm mechanism turned either manually or by means of a motor.  As the nuts rotate on their respective connection screws, the slide will be raised or lowered relative to the ram and to the bed of the press thereby adjusting the shutheight opening between the slide and bed.  The adjustment mechanism is locked by means of a wedge-shaped split ring disposed between the nuts.  When the split ring is contracted by means of an operator actuated lock screw, the nuts will be urged in opposite directions so as to take up the running clearance of the double nut in its housing.  Since the normal thread clearance for the lock screw will  also be taken up, the entire adjustment mechanism will be locked against movement until the lock screw is released.

Abstract: Abstract of the Disclosure A soil preparing device for preparing forest soil to a planting bed. The device comprises a frame intended to be mounted on a forest tractor, a support arm mounted on the frame pivotally around a hori-zontal link, and a preparing element supported by a slide mounted vertically movably on said support arm. The slide is fastened to a hydraulic cylinder supported by said support arm for continuously adjusting the vertical position of said slide and, accordingly, of the position of the preparing element with respect to the ground during the preparation. A deviation of the support arm upwardly or downwardly from a neutral position activates said hydraulic cylinder of the slide to displace the preparing element upward, and downward, respectively, due to variations in the ground level and obstacles on the ground. The preparing element can therefore be displaced clear of any unevennesses in the ground without substantially deviating from its working angle in relation to the ground.

Abstract: ABSTRACT OF THE DISCLOSURE       Radioactive materials are used to assist in starting a discharge in an electrodeless light source.  The radioactive emissions predispose on the inner surface of the lamp envelope loosely bound charges which thereafter assist in initiating discharge.  The radioactive material can be enclosed within the lamp envelope in gaseous or non-gaseous form. Preferred materials are krypton 85  and americium 241.  In addition, the radioactive material can be dispersed in the lamp envelope material or can be a pellet imbedded in the envelope material. Finally, the radioactive material can be located in the termination fixture.  Sources of alpha particles, beta particles, or gamma rays are suitable. Because charges accumulate with time on the inner surface of the lamp envelope, activity levels as low as 10-8 curie are effective as starting aids.

Abstract: RECIRCULATING RMS AC CONVERSION METHOD AND APPARATUS                Abstract of the Disclosure A signal whose RMS value is to be accurately determined is first converted into DC form by a relatively inaccurate RMS converter, such as a thermal RMS converter. The result is a first converter signal (Y1), which is stored for recirculation in a suitable storage device, such as a sample and hold circuit. The first converter signal is also doubled (2Y1) and stored. Thereafter the first converter signal stored in the storage device is recirculated to the converter to create a second converter signal (Y2). Then, the second converter signal is subtracted from the doubled first converter signal (2Y1 - Y2) to produce a highly accurate RMS output signal.

Abstract: ABSTRACT          The frame of an article of reclining furniture supports an under-mattress which comprises a back member and a foot member. The back member is mounted for pivotal movement about an axis in such a manner that upon pivotal displacement the inner end portion thereof is moved under the pivot axis and forms a sitting depression.  In order to ensure for the occupant an anatomically correct support of his seat and back in all possible sitting positions and also to maintain this support even when changes of position are performed, an intermediate member is inserted between the back member and the foot member.  This intermediate member is suspended at the adjacent ends of the back member and the foot member by means of joints and therefore together with the back member and the foot member, which is movable longitudinally of the article, it forms a system of joints which responds to magnitude and point of attack of the load and compensates for anatomical differences and permits the occupant any desired change of his sitting position.  Dependently upon whether the changes his position forwards or backwards, the intermediate member will be flush with the back member or the foot member and thereby ensure always a correct support of the entire spine.  The movable connection of the intermediate member with the adjacent ends of the back member and the foot member is effected preferably by means of an elastic joint whose two limbs of which are provided with teeth, so that in its closed position the joint may absorb without difficulty even vertical continuous loads.  Thanks to elastic suspension of the intermediate member and the location of all metal parts into the interior, damage to the bed linen as well as accidents (finger injuries by clamping in) are largely avoided.

Abstract: ASYNCHRONOUS TRANSMISSION SYSTEM FOR BINARY-CODED INFORMATION ABSTRACT OF THE DISCLOSURE An asynchronous transmission system for binary coded information is disclosed. According to this system, in a transmitting terminal (A), when successive data of the same code in asynchronous data lasts for a predetermined period (T1) of time, a refresh pulse the polarity of which is opposite to the successive data is added to a transmission signal. However, the addition of such a refresh pulse to the transmission signal is inhibited for a predetermined period (T2) of time before a change of data. In a receiving terminal (B), a pulse, the width of which is larger or equal to a minimum period of data, and a pulse, the width of which is smaller or equal to a pulse-width (T0) of a refresh pulse, can be discriminated by a pulse-width discrimination circuit (6). As a result, such a refresh pulse is not present in the output signal of the pulse-width discrimination circuit. Thus, asynchronous data is restored.
