Abstract: ABSTRACT OF THE DISCLOSURE     In a leather tanning process, animal skins are treated with a tanning agent comprising an aluminium (III)/titan-ium (IV) mixed complex  with a salt of a polyhydroxymono-carboxylic acid as a masking compound. The masking compound preferably has the general formula:    HOCH2(CHOH)n CO2M wherein M is an alkali metal, and n is 2 to 6. Especially preferred masking compounds are sodium gluconate and sodium glucoheptonate. The same process can be used for a wide range of skins, both as a base tannage and in comb-ination with other tanning processes.

Abstract: INVENTOR:  Henry C. Latka A SYSTEM FOR CONTROLLING THE DIAMETER OF A CRYSTAL IN A CRYSTAL GROWING FURNACE            ABSTRACT OF THE DISCLOSURE     A crystal growing furnace has lift and rotation control apparatus for both a growing cyrstal and a crucible containing a melt.  A transducer and a servo motor are disposed above the furnace having respective shafts connected along a common horizontal axis on opposite sides of a longitunal light tube wherein the light tube and transducer shaft can be axially positioned by the shaft of the servo motor.  The light tube has a lens for focusing at times on a spot on a meniscus in the furnace and at times on the melt, a light sense detector is connected to the light tube for at times generating a servo motor control error signal to drive the servo motor incremen-tally to an angular position corresponding to growth in the diameter of the meniscus by tracking a spot on the meniscus.          The transducer generates an output signal indicative of incre-mental angular movement in response to growing the crystal for governing the lift and rotation control apparatus.

Abstract: Magnetic Resonance Imaging Method Abstract Hybrid fast scan magnetic resonance imaging is performed by using, for example, both a two dimensional Fourier transform (2DFT) method using phase encoding prior to data collection and an echo planer technique which phase encodes by using an oscillating gradient during data collection.  In this hybrid imaging, the amplitude of the oscillating gradient determines the time savings achieved in imaging.  The hybrid scan has particular application for medical diagnostic imaging since it is advantageous that such imaging be conducted as rapidly as possible.

Abstract: ABSTRACT            A Pneumatic Hydro-Electric Power Conversion System The invention provides for the generation of electrical power from low head water, such as the flowing water of rivers or the like, the electrical power is generated by passing the water in sequence over flexible bags or membranes to displace air under the flexible bags or membranes. The displacement of the air is utilised for the driving of a power generator such as an air turbine, and smooth power flow is achieved by diverting air displaced from the underside of one membrane into the cavity under the other membrane. The water flows over the  membranes  in sequence so that a self oscillating system is set up with the air being displaced back and forth from the cavities, and the displacement air being used to drive the air turbine. Preferably a bi-directional air turbine such as a Wells turbine is used.

Abstract: ABSTRACT OF THE DISCLOSURE          A braked knee joint having a thigh part and a lower leg part which are provided with braking surfaces adapted to one another and which, because of the capacity for axial movement of the thigh part relative to the lower leg part, are pressed against one another during loading. The braking surfaces essentially have a contour which is circular in vertical section and which has a constant radius relative to the rota-tional axis. The joint includes a suitable stop to produce a jerk-free termination of the extension movement of the knee joint out of the flexed position. The stop is formed by providing the braking surface of the thigh part with a front end piece which is at a distance which increases from the rotational axis and is greater than the constant radius, and by providing a corresponding front end piece of the braking surface of the lower leg part so that, with increasing extension of the knee joint in the unloaded condition, a constantly increasing area of the braking surfaces comes into frictional contact and thus forms the stop.

Abstract: PHASE SHIFTER CONTROL                ABSTRACT OF DISCLOSURE        A scanning system for a phased array antenna for operation at a selected frequency between a first frequency and a second frequency includes the storage of phase shift command signals for each of the phase shifters coupled to radiating elements of the antenna.  The memory which stores the phase shift commands is addressed sequentially to provide for a step-wise scanning of a beam of radiant energy at a first frequency of the antenna.  The addressing is accomplished by incrementing a count resulting from a counting of clock pulses.  Compensation for the stepped positions of the beam for the difference between the selected frequency and the first frequency is accomplished by altering the number of pulses which increment the count of the addressing. The altering is accomplished by the storing of sequences of clock pulses at varying temporal spacings which are used for gating out selected ones of the incrementing pulses.

Elongated connectors of re-silient material with generally U-shaped section have a rear connector portion having an inwardly extending upper tree end poriton forming a recess between the free end portion and an adjacent part of the rear connector to receive an upper end of the rear portion of an eaves troughing member.  The front portion of each connector member has a longitudinally extend-ing projection in a rear face shaped for snapping engagement in the recess of an eaves troughing member.  A connector member can be assembled with adjacent eaves troughing members, when they are longitudinally aligned with each other with ends substantially abutting, by initially causing the upper ends of the rear portions of the eaves troughing members to be received within the recess of the connector, with the remainder of the connector being below the eaves troughing members.  The con-nector is then moved angularly upwardly relatively to the eaves troughing member to cause longitudinal projection of the connector to move into the recesses in the front faces of the front portions of the eaves troughing members and snap into engagement therewith with the rear portion, base portion and front portion of the connector engaging the corresponding portions of the eaves troughing members.

Abstract: PLASTIC PIPE WITH INTEGRAL END CONNECTION   AND METHOD FOR JOINING          ABSTRACT OF THE INVENTION    Polyolefin pipe having an integral end connection.  The pipe is fabricated with male and female end connections in order that the pipe may be press-fitted together with the interior and exterior forming a flush uninterrupted surface.          One or more radial ribs and grooves are formed on the inter-ior of the female connection while a registering series of ribs and grooves are formed on the exterior of the male connection.  The ends of the pipe are bevelled in order that the ends pressed together engage and by the slight resiliency of the polyolefin pipe construction permit the slight expan-sion and contraction of the ends to provide a locking interfit of the respective ribs and grooves in the two ends.  The wall thicknesses of the end connection and width of the ribs and grooves are particularly dimensioned in  order that the male end may be inserted to a complete lock position without premature engagement and that should failure occur, it be at the readily observable pipe wall rather than in internal rib.          Sides of the ribs may also be bevelled to provide for dis-engagement of the pipe ends when pulled apart.
