Abstract: STABILIZATION OF LASER OUTPUT            Abstract of the Disclosure Signals derived from a moving shuttle table are utilized to trigger a cavity-dumped YAG  laser whose output pulses are directed to machine successive lines of an iron oxide film in a spot-by-spot manner.  Machining of the film to form a high-quality reticle requires that the amplitude of the laser output pulses be maintained relatively constant even in the presence of mechanical vibrations and electrical noise which  ordinarily tend to produce large fluctuations in the output power of the laser.  This is achieved by interposing a phase-locked loop between the output of the shuttle table and the input of the laser.  In addition, the loop enhances the machining operation by providing a capability to easily multiply the repetition rate of the pulses derived from the table.

Abstract: ABSTRACT OF THE DISCLOSURE        Plastic or metal connectors comprise U shaped channel members into which interconnecting shelf panels engage to hold the panels in position.  The basic channel length is made up to suit the interconnection required.  For example two channels at right angles to one another can be used to hold two shelf members at right angles to one another at a corner.  Three channel members in a T formation can be used to hold one panel perpendicular to another intermediate the ends of the other panel and a cruciform shaped connector can hold panels which intersect at 90° to one another.  By constructing the connec-tors to suit various types of panel connections encountered, any shelf arrangment can be constructed readily and easily and without the use of tools or screws.

Abstract: WORD LINE CLAMPING CIRCUIT     Abstract of the Invention A word line clamping circuit for use with field effect tran-sistor memories is disclosed which permits the clamping of the word line to a reference potential using a minimum of devices and without the consumption of d.c. power so that multi-level bit line potentials may be utilized during the memory cycle.  This is achieved by connecting a field effect transistor (FET) between word line and ground under control of a word line decoder so that a node associated with the last mentioned FET is held in either an uncharged or charged condition depending on whether the decoder is selecting its associated word line or not selecting it.  Because the unselected word lines are held at ground during a portion of the memory cycle when reading or writing of memory cells associated with a selected word line is taking place, any capacitive coupling which might change the content of cells associated with unselected word lines is avoided and, for whatever the reason, bit line potentials may now be changed to different levels without affecting information storage during the memory cycle.  Two circuits are shown which, under control of the word line decoder, permit the grounding of unselected word lines during at least a major portion of the memory cycle.

Abstract: Abstract A power transmitting mechanism for converting the thrust of reciprocating pistons to a rotary output shaft at speeds independent of the frequency of piston reciprocation.          Power developed by expanding gases in accordance with well-known thermal cycles, such as the Stirling cycle, is transmitted by pistons to a bed plate capable of swashing motion about a point on the axis of the output shaft.  The shaft is provided with a pair of oppositely convergent or biconical friction surfaces engageable by annular tracks carried with the bed plate in orbit which may be characterized as nutational.  Axial adjustment of the annular tracks toward and away from the point on the output shaft varies the output shaft shaft independently of input speed or piston frequency.

Abstract: SPORT GLOVE Abstract of the Disclosure The disclosure relates to an improved sport glove con-struction comprising loosely but securely connected inner and outer glove shells of different constructions, each contributing sig-nificant and desirable characteristics to the combination.  The inner glove is constructed of a highly elastic, stretchable mate-rial, so constituted as to be received tightly over the entire hand of the wearer, snugly enclosing and conforming to the indi-vidual fingers and thumb, as well as the palm and back areas of the hand., The construction of the elastic inner glove shell is such as to provide a secure yet comfortable feel to the glove. The elastic inner glove is entirely enveloped by a second or outer glove of a material and construction selected to provide appro-priate gripping and other characteristics.  The outer glove may be of a somewhat elastic material, such as knitted fabric, but may also be of a relatively nonelastic material, such as leather, vinyl or the like, or may be a combination of materials.  The inner and outer-glove shells are attached securely but loosely at se-lected areas, to permit easy donning and doffing of the glove while at the same time accommodating the necessary degree of elas-tic expansion of the inner glove shell relative to the outer shell when the glove is applied to the hand.
