Abstract: D-23,200 SWITCHED-CAPACITOR SOURCE RESISTOR                        SIMULATION CIRCUIT by Man Shek Lee Abstract of Disclosure An integrated circuit comprising first and second nodes that are connected to external circuitry, a voltage follower having input and output terminals electrically connected between the second node and the bottom plate of a first integrated capacitor C1, and second and third integrated capacitors C2 and C3 having the bottom plates thereof connected to a ground reference potential.  A switch means is operative for periodically electrically connecting the top plate of C1 to the first and second nodes during first and second non-overlapping time periods in each time interval T for discharging C1 and charging C1 to the difference voltage across the nodes, respectively, where T is the time interval between adjacent second time periods and f=1/T is the switching frequency for C1.  The switch means also operates for periodically electrically connecting the top plates of C2 and C3 to the second and first nodes.  The circuit simulates a source resistor when the first node is electrically connected to the output terminal of a voltage source that is connected to ground.  This circuit configuration simulates a bilinear source resistor when the capacitances of C1, C2 and C3 are the same values, and the circuit is characterized by the bilinear transformation.

Abstract: Docket No.           ABSTRACT OF DISCLOSURE     The valve assembly for use with high temperature and high pressure fluids has inner and outer spaced shells and a valve actuator support of inner and outer spaced members which are connected at their end portions to the inner and outer shells, respectively, to extend substantially normal to the longitudinal axis of the inner shell. A layer of resilient heat insulating material covers the outer surfaces of the inner shell and the inner actuator support member and is of a thick-ness to only occupy part of the spaces between the inner and outer shells and inner and outer actuator support members. The remaining portion of the space between the inner and outer shells and the space between the inner and outer members is substantially filled with a body of castable, rigid refractory material. A moveable valve member is disposed in the inner shell. A valve actuator assembly is supported in the valve actuator support to extend into the inner shell for connection with the moveable valve member for movement of the moveable valve member to positions from a fully open to a fully closed position to control flow of fluid through the inner shell. An anchor means is disposed adjacent opposite sides of the axis of the valve actuator support and attached to the inner shell so that rela-tive radial movement between the inner and outer shell is per-mitted by the layer of resilient heat insulating material and relative longitudinal movement of the inner shell to the outer shell is permitted in opposite directions from the anchor means to thereby maintain the functional integrity of the moveable valve member by providing an area of the inner shell surrounding the movable valve member longitudinally stationary, but at the same time allowing radial movement.

Abstract: ABSTRACT OF THE INVENTION         A  portable  drying  rack  is  provided  which  com-prises frames of unitary construction for hanging articles and support members for supporting the rack in an upright position. The support members are pivotably attached to the frame  to  permit  the  drying  rack  to  be  collapsed  for storage.  The  pivotable  attachment  between  the frame  and support members is accomplished by means also of unitary construction.  The unitary construction employed throughout the present invention allows a light-weight drying rack to be formed utilizing inexpensive injection molded plastic.          Additionally,  because  of  the  unitary  construction,  the number of components forming the rack is decreased over the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE        The invention relates to a process for the preparation of fodder yeast and/or ethanol from plants or cellulose-containing wastes of plant origin. Accor-ding to the invention the cellulose-containing starting substance is pre-treated with a dilute mineral acid and/or a dilute base, and then fermented under aerobic or anaerobic conditions in the presence of a Candide utilis var. cellulolytica strain deposited at the Hungarian National Collection of Microorganism of the National Institute for Public Health on 23rd September, 1980 under No. CU 28 00199. When fermentation is performed under aerobic conditions, fodder yeast or a mixture of fodder yeast and ethanol is obtained, depending on the aeration rate, whereas when fermentation is performed under anaerobic conditions, ethanol is obtained. By use of a yeast strain which is both suitable for animal fodder and capable of decomposing hydrated and partially degraded cellulose, the process provides a way of producing animal fodder directly from cellulose.

Abstract: Otis 4-111 TEST TREE     Abstract of the Disclosure A subsurface test tree so compact in its vertical dimen-sion that the entire tree can be positioned below the blind rams in a blowout preventer stack.  When the stinger is removed the remaining valve section of the tree will be below the blind rams in any conventional blowout preventer stack.    The valve operators are split, one carried by the stinger and one carried in the valve housing with the arrangement of operator and valve in the housing providing an extremely small vertical dimension. A dome charge is effective on a piston to drive a ball valve to closed position to cut a line extending through the ball valve and to provide sequential operation between the ball valve on bottom and the valve thereabove which may be a flapper valve so that the lower valve closes and the line is cut before the upper valve closes.    In one form the invention includes a subsurface safety valve below the test tree operated by one of control or balance pressure fluid.

Abstract: Abstract of the Disclosure The invention relates to a pipe clamp for holding a pipe under high pressure.  The clamp comprises two symmetrical clamping jaws preferably of hard plastics, arranged around the pipe and fastened to a base support e.g. by means of threaded pins and tension nuts.          Between the clamping jaws and the base support is provided a plate of an elastic material dampening sound waves, and between the clamping jaws and the threaded pins being in direct contact with the base support are provided sleeves of a similar material.          Thus disturbing noise is not transferred from the pipe to the base support and a secure clamping of the pipe is achieved as the sound insulation members also take up thermal expansion movements of the pipe.

Abstract: ABSTRACT OF THE DISCLOSURE A neutron-absorber  body  for  use  in  burnable poison rods in a nuclear reactor.  The body is composed of a matrix of Al2O3 containing B4C,  the neutron absorber.          Areas of high density polycrystalline Al2O3 particles are predominantly encircled by pores in some of which there are  B4C particles.  This body is produced by initially spray drying a slurry of Al2O3 powder to which a binder has been added.  The powder of agglomerated spheres of the Al2O3 with the binder are dry mixed with B4C powder.  The mixed powder  is  formed into a green body by isostatic pressure and the green body is sintered.  The  sintered body is processed to form the neutron-absorber body.  In this case the B4C particles are separate from the spheres resulting from the spray drying instead of being embedded in the sphere.

Abstract: ABSTRACT OF THE DISCLOSURE   A device is disclosed for shaping one end of a steel billet heated to forging temperature in order to form an extension useful as a tong hold.  The device is adapted for working with a press and operates such that the movement of the press ram down and up results in completion of the shape of the tong hold.  This is achieved by a wedge-shaped member normally secured to the  ram of the press and by a specially designed workpiece holder cooperating with cutters and with an anvil, all responsive to the operative movement of the ram of the press.  The device is simple in structure and can be relatively easily adapted for use on virtually any press.  There are very few parts of the device that have to be replaced when effecting changeover from one type of billet to another.
