Filed: 1988-07-13
Granted: 1992-02-04
Abstract: ABSTRACT        A C-shaped brace member threadedly receives a screw shaft and supports a channel-shaped die.  The lower end of the screw shaft is connected by a ball and socket joint to a pair of hinged pressure plates positioned in parallel relation with the opposite walls of the channel-shaped die.  Rotation of the screw shaft in a preselected direction raises and lowers the shaft to extend and retract the pressure plates toward and away from the walls of the base member.  An end portion of a gutter section to be expanded is positioned on the base member between the longitudinal edges of the pressure plates and the walls of the base member.  Downward movement of the screw shaft moves the pressure plates outwardly toward the walls of the gutter section.  The pressure plates contact the walls of the gutter section and bend the walls outwardly to expand the width of the gutter section until further expansion is restrained by the walls of the base member.  Rotation of the screw shaft in the opposite direction retracts the pressure plates to permit removal of the expanded gutter section from the base member.

Abstract: Two follistatin proteins with inhibin-like activity were isolated from porcine follicular fluid using heparin-Sepharose affinity chromatography, followed by gel filtration on Sephacryl S-200 and then six steps of high-performance liquid chromatography. Each isolated molecule is a monomer having a molecular weight of at least about 32,000 daltons. Microsequencing revealed the NH2-terminal portions both to be Gly-Asn-Cys-Trp-Leu-Arg-Gln-Ala-Lys-Asn-Gly-Arg-Cys-Gln-Val-Leu. The larger protein has 315 residues and is believed to be glycosylated. The smaller protein is a 288-residue, C-terminally shortened version thereof. These proteins specifically inhibit basal secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system. The half-maximal effective dose for both is 2.5-6.0 ng/ml. Human and rat follistatins exhibit very high homology with the porcine protein, with the human differing from porcine in only 4 residues out of 315 and with the rat differing from porcine in only 8 residues out of 315.

Granted: 1992-06-09
Abstract: ABSTRACT      A fluidic oscillating nozzle that oscillates a fluid jet at high frequency by the use of fluidic amplification technology with no moving parts.  The jet that issues from the nozzle is a zero-degree jet of fluid that maintains a very high energy density;  however,  due  to  its oscillation,  its appearance is that of a fan-type jet that disperses at a  fan angle from the nozzle.   At a nominal distance  from  the  nozzle,  the jet  covers  the surface with a relatively broad area of flow while maintaining high energy impact density due to the impact  effects  of  the non-expanding  zero-degree jet.

Abstract: ABSTRACT OF THE DISCLOSURE     An ammunition unit  is disposed for firing from a gun. The ammunition unit is provided with a fuze which includes electronics with an associated electrical trajectory safety device (BA) which prevents arming of the ammunition unit within a trajectory safety distance. A movable portion (8) may be activated with the aid of an  arming  igniter  (10)  which  is  actuable  with  the electrical trajectory safety device (BA).  upon  its activation, the movable portion executes  an  instantaneous movement  in which it moves a bursting cap (12) disposed in the movable portion into an arming position  (12')  in  register with the  initiation  detonator  (11) which is included in a detonation chain actuable by means of an impact or a proximity fuze contact. The movable portion (8)  is also lockable by locking means  in the form of  a pin which  is actuable on a retardation in the ammunition unit caused by a first hit of the ammunition unit against a first object located within the trajectory safety distance. Upon its activation, the locking device  realizes  a  locking  of  the  movable  portion  which  is thereafter   prevented   from   executing   the   above-mentioned instantaneous movement even if the first hit were to cause such mechanical action on the electronics as entails activation of the arming  igniter. Thereby,  the  ammunition unit will,  on a second hit, assume the safe position entailing that total bursting of the ammunition unit through the intermediary of the bursting cap is prevented if such bursting is caused by shock-triggering of the bursting cap in the unsafe position.

Abstract: ABSTRACT OF THE DISCLOSURE            Solvent dewaxing of waxy hydrocarbon oils using scraped surface chillers is improved by injecting cold solvent into the scraped surface chillers at multiple points to augment the indirect chilling occurring in said scraped surface chillers.  In utilizing this multi-point cold solvent injecting process it is important to control the  .DELTA.T occurring at each injection point within each chiller bank across the entire chiller train.            The .DELTA.T at each injection point attributable only to cold solvent injection must be equal if one is to secure the benefit of the present invention which is an improved liquids/solids ratio without deterioration of the feed filter rate.            Preferably, to avoid any possible deterioration of filter rate and/or liquids solids, the cold solvent injection should be completed prior to the slurry in the scraped surface chiller train experiences any shock chilling.

Granted: 1994-01-18
Abstract: ABSTRACT          A  fast  packet  switching  system  includes  an interconnection network with a distributed control structure composed of multiple processing units which manage routing of calls at a virtual call level. Some of the processing units, each associated with a group of network inputs or outputs, store bandwidth occupancy data relevant to links between stages accessible from or to the inputs or outputs of the group and between those inputs or outputs and a central network stage providing a maximum number of alternative paths, the data being updated whenever a new call has been routed. When the routing of a new call is to be decided, the processing  units  associated  with  the  input  and  output involved in the connection evaluate each possible routing, on the basis of the updated data which they store as to bandwidth  occupancy,  and  according  to  the  bandwidth requirements of the new call, so as to provide a partial cost function of the portion of each possible routing through the links in respect of which they hold bandwidth occupancy data. One of the units involved combines the partial cost functions for each complete routing, selects that providing the minimum cost function, and forwards the call on that routing.

Title: Depth buffer clipping for window management
Inventor: LOUCKS LARRY K
IPC: G06F3/048
Filed: 1989-08-18
Granted: 1993-10-19
Abstract: DEPTH BUFFER CLIPPING FOR WINDOW MANAGEMENT ABSTRACT      In a computer system having a display adapter, a refresh buffer and an interactive display terminal with a screen display on which is formed a plurality of at least partially overlapping windows, a depth buffer is added to the display adapter for providing clipping assistance to the software-based window manager in the CPU. The window manager is programmed to monitor the current depth position of each of the plurality of windows.  In response to an input request for a rearrangement of the windows, the window manager assigns a new depth value to the subject matter associated with each affected window and requests  that each  application  retransmit at  least the  affected subject matter.  The depth buffer includes an array which stores the depth values of the subject matter associated with each of the windows being  currently  displayed  on  the  screen.    In  response  to  the rearrangement request, depth buffer receives the new depth values for the subject matter associated with each affected window from the window manager  and  compares  the  current  depth  values.    If  the comparator determines that the new subject matter has a depth value associated with the same window or a window closer to the viewer, the depth  buffer  notifies  the  refresh  buffer  to  store  the  newly transmitted subject matter from each of the applications being run on the CPU.   In an alternative embodiment, two buffers are used to store the depth information associated with the subject matter in a window, i.e. a W-buffer to store the depth of each window relative to a reference point and a Z-buffer to store the depth of the subject matter within a window.

Abstract: EXTENSION DECELERATION ORTHOTIC HINGE     ABSTRACT OF THE DISCLOSURE           An extension deceleration orthotic fulcrum for knee and elbow braces, which simultes performance of the function of those ligaments that control joint motion and provide anteroposterior joint stability, comprising a lightweight, external spring assembly, upper and lower elongated arms, and a centric or polycentric fulcrum, which is adjustable for its range of motion, adaptable for use on many different style orthoses, and whose strength can be varied to suit corrective, preventive, anthropomorphic, environmental, and usage requirements, including means both for mechanically dampening the limb's angular velocity on extension to prevent hyperextension and for accelerating the limb's angular velocity on flexion to enable quicker, smooth, less stressful motion.  In one embodiment, spring rods are assembled medially and laterally to conventional pairs of elongated orthotic brace arms to span the joint fulcrum by serpentinely engaging novel roller posts, the assemblage thus serving to decelerate the limb during the last 15 to 20 degrees of extension, to help prevent the striking of a stop with its attendant risk of hyperextension, and thus serving to use the stored energy of the spring to facilitate flexion of the limb. A method of manufacture is also provided, which facilitates and speeds assembly of the or orthotic fulcrum to an orthosis.
