Abstract: ABSTRACT OF THE DISCLOSURE            In a slide fastener employing coupling elements secured within folds of supporting tapes by clamps secured over the folds, clamp legs are formed with raised land areas and lips for cooperating with flange edges and upper surfaces of bases of the elements, and the inside surfaces of heels of the clamps are formed flat for cooperating with bottom surfaces of the elements to accurately position the elements relative to the clamps.  Reduced thickness of the junctions between legs and heels relative to the thickness of central portions of the legs and heels produces corners receiving displaced tape material from between the raised land areas of the legs and the outer edges of flanges of the coupling element as well as from between the bottom surfaces of the bases of the coupling elements and the flat inner surfaces of the heels.

Abstract: REAL TIME CLOCK RECOVERY CIRCUIT     Abstract of the Disclosure This invention relates to a real time clock recovery circuit.  The clock recovery circuit requires three inputs, a bit serial data received input (BSD), a quarter bit delayed (QBT) and a three quarter bit de-layed (TQBT) signal. The three inputs are derived from a single raw input that becomes the received input (BSD) signal.  QBT and TQBT are delay line versions of the BSD signal.  The three inputs (BSD, QBT and TQBT, and the complement of these signals) are ANDed together to detect low frequencies.  The generated signal indicative of the low frequency, QBT and TQBT generate a recovered clock by state sequencing of an R-S latch.  The type of bit serial data stream which may be inputted to the circuit of the present invention is double frequency encoded data streams, including Manchester or diphase encoded.

Abstract: J. Bitterly 41-180/Bil.7 STRUCTURAL MEMBER            ABSTRACT OF THE DISCLOSURE     The structural member of the present invention  in-cludes  a  pressure  tube  either  having  a cable  tensioned between its ends or being mounted within an outer member.          The pressure tube is mounted such that it can move axially with respect to the cable or the outer tube.  When the tube is pressurized,  some  of  the  force  is  absorbed  in  hoop stress in the tube, and some of the force is directed to the ends of the pressure tube and to the cable or the outer member either through a piston arrangement or otherwise.          When compressive loads are placed on the system,  it can support force up to the preload without exhibiting Euler buckling.  The system is useful for long, thin columns and for long beams where ridgidity is important.  The pressure tube is not subject to compressive loading because its ends are free to move axially without compressing the tube.  The pressure tube may be wrapped in high tensile strength uni-directional fiber material to withstand higher hoop strees.

Abstract: A B S T R A C T            The present invention relates to an attachment device for mounted transmissions, more particularly for planetary gear trains with torque supports used to drive bucket wheels or the like.  Previous means for attaching such transmissions to bucket wheels required a relatively large space between the transmission and the bucket wheel.  The present invention minimizes the distance between the transmission and the bucket wheel by use of a serrated drive shaft of the trans-mission which is inserted into a matching internal profile of the bucket wheel.  The transmission is attached by means of a connecting shaft running from the end face of the drive shaft coaxially through a central bore in the bucket wheel, to the other side thereof, where the free end of the connecting shaft is secured, preferably resiliently, in relation to the end face of the bucket wheel.

Abstract: ABSTRACT OF THE DISCLOSURE             This specification discloses a method for the production of combustible gas and a device for the application of the method.  A gasifiable material is fed by means of a screw device in to a drum equipped with lip screens and mounted in a twin-shell casing, the material in the drum being displaced longitudinally to a gas discharge part, where incombustible material is discharged through a hatch onto a screw device and is then discharged through a sluice device.  At the same time the incoming air is guided by means of the lip screens into the bottom of the drum in a direction opposite to the direction of rotation of the drum, in order to keep the material floating along the bottom, whereas the intermediate space of the casing is caused to cool the inner shell and to heat the primary air admitted under the drum and drawn through or forced into the drum.  Thus an air chamber is fitted to ensure the correct velocity of the intake air, whereas the material fed into the drum is in compact form and the flue gases are caused to flow through a vibrating filter assembly typically containing lime-stone and are then discharged through an opening.  The gasifiable material may consist of refuse, peat or similar material.
