Abstract: ABSTRACT OF THE DISCLOSURE   A processing machine particularly for boiled/cooked crab comprising a shell crusher means (2) and a subsequent separation means in which the crab meat is separated from the shell fragments. The separation means of the machine is novel in that it embraces a plurality of upright, spinning, screw-threaded spindles (12). These spindles are arranged in a circle in a spinning meat collection tray(13) for crab meat with just sufficient clearance between adjacent spindles thatthe crab medium which is discharged into the circular space defined by the said spindles (12) in the said spinning meat collection tray (13) is pressed, by centrifugal force, out against the said spindles (12), where it can pass betweenthe adjacent spindles (12) aforesaid, while almost the entire bulk of hard shellfragments are prevented from passing between the said spindles (12). The gradient of the screw thread of the spindles and their direction of rotation combine to drive the shell fragments upward and into an overlying shell collection tray (10), while the crab meat makes its way to the outer portion of the said rotary meat collection tray (13) confining the ring of spindles (12) aforesaid.          (Figure 1)

Title: Pick function implementation in a parallel processing system
Inventor: ARANDA MICHAEL A
IPC: G06F3/048
Filed: 1990-07-20
Granted: 1995-06-27
Abstract: A  processing  system  for  identifying  operator selection of a graphics object in a system using parallel pixel generation.  Parallel pixel generation results in a fragment comprising a series of M pixels being generated at each processing cycle.   The image fragment must be tested against  an operator defined  selection area  to determine whether the object being generated falls within the operator  selection area.   Fragments  are  initially classified as totally within or totally outside of the area.   If a fragment intersects the operator selection area, applying a mask for each boundary of the operator defined area.   Selection is  signalled based upon  the logical  combination  of  the  masked  image  fragments. Operator selection or picking occurs without the overhead of maintaining a pick RAM for the X and Y dimensions.

Title: Livestock barrier
Inventor: KLATT WAYNE
IPC: A01K15/04
Filed: 1990-10-23
Granted: 1994-04-05
Abstract: ABSTRACT   A portable livestock barrier is disclosed which includes a rigid metal panel of open grid construction that is arranged to rest in a normal operational position that is parallel to the ground to thus form a raised grid which livestock will not cross but which can be flattened to the ground against a resilient return force when a vehicle is driven across it.  The rigid metal panel is supported by a resilient suspension which permits the panel to tilt with respect to its normal operating position and to be forced flat against the ground when the weight of a vehicle is applied to it.  The livestock barrier does not require a pit or special surface preparation for its installation.  It may be quickly installed on any solid, relatively level surface.  The unit is transportable and it can be readily moved from one location to another without disassembly.

Abstract: Abstract of the Disclosure A signal generating apparatus of this invention includes a timing signal generation unit (N), a signal generation unit (M) for generating a desired signal on the basis of a timing signal generated by the timing signal generation unit (N), and a signal synthesizer (s).  The timing signal generation unit (N) includes a first counter (N1), a coincidence discrimination circuit (N2), a second counter (N3), a timing signal generator (N4), and an identification signal generator (N5).  The timing signal generation unit (N) generates a timing signal for inserting the pattern signal in a predeter-mined portion.  The signal generation unit (M) includes an additional signal generator (M1), an overhead signal generator (M2), and a pattern signal generator (M3).  The signal synthesizer (S) synthesizes the pattern signal with the additional signal and the overhead signal, and outputs a synthesized signal.  The coin-cidence discrimination circuit (N2) receives address information representing a desired information signal position.  The second counter (N3) and the timing signal generator (N4) perform substantially predetermined operations for the address information at an arbitrary position.

Title: Adjustable keyboard support
Inventor: MOORE EDWARD
IPC: A47B21/00
Filed: 1990-12-18
Granted: 1995-09-12
Abstract: An adjustable keyboard support, for holding keyboards for computer terminals, drawing boards, digitizing pads and similar items, comprising a support frame which is pivotally mounted below the top surface of a terminal support stand.  The support frame has spaced extendable and retractable side members, each side member having a rear member and front member. Each front member is slidably mounted on a rear member. Each rear member is pivotally attached at its rear end to the terminal support stand.  A lever extends between a forward part of the terminal support stand and an intermediate position on a forward member, for each side member.  Extension of the support frame swings the levers around and forward, the front members first moving down further extension causing the front member to move up as continued swinging of the levers occurs. In a further embodiment, the support provides a moveable keyboard carriage.  The carriage may be vertically elevated and angularly inclined with respect to the support frames; suitably positioned levers facilitate the motion.

Granted: 1994-01-25
Abstract: APPARATUS AND METHOD FOR DETECTING THE POWER LEVEL    IN SINGLE AND MULTI-STRIPE INTEGRATED LASERS                         ABSTRACT OF THE DISCLOSURE The purpose of the present invention is to provide an apparatus for detection of a laser output on a semiconductor wafer, especially where the laser and detector are formed by similar or simultaneous processes on the same substrate. A laser cavity and a detection cavity are formed on a semiconductor wafer. The two are formed in parallel such that each has a generally axial orientation. Light emitted laterally from the laser cavity is detected by the detection cavity. The amount of light detected can then be transformed into data, which in turn can be used to control the output of the laser. Advantages of the present invention include the ability to simultaneously form the laser and detector portions, the detector portion so formed does not interfere with the beam being provided by the laser, and the ability to integrate multiple laser-sensor pairs in a semiconductor device.

Title: Radar apparatus with jamming indicator and receiver device with jamming indicator
Inventor: DIJKSTRA JAN ALBERT
IPC: G01S7/36
Filed: 1991-06-06
Granted: 1998-04-28
Abstract: The invention relates to a radar apparatus having a wideband preselector filter (15), a wideband preamplifier (16), a narrowband IF filter (19) and a jamming indicator (11). In order to obtain a warning against a jammer being active within the large bandwidth of the preselector filter (15) but outside the narrowband IF filter (19), the jammer indicator (11) has the same bandwidth as the wideband preselector filter and is connected after the preamplifier (16), but before the narrowband IF filter (19). A warning is necessary as a jammer of this type may greatly reduce the sensitivity of the radar apparatus by saturating the preamplifier (16).
