Title: Keyboard enhancer

Granted: 1991-04-16
Abstract: KEYBOARD ENHANCER                   Abstract of the Disclosure A method and apparatus for enhancing the operation of computer keyboards is disclosed.  The invention allows touch-typing of nontouch-type keys by detecting a triggering sequence in the touch-type keys.  For example, by holding down the Space Bar while depressing and releasing a second key and before release of the Space Bar, the Space Bar is seen to act as a Control key.  Furthermore, the functions of nontouch-type keys may be superimposed upon touch-type keys and accessed in a similar manner.  The invention interprets make codes which are generated by the keyboard when a key is depressed and a break code which is generated by the keyboard when a key is released. If a triggering sequence of codes is detected, then the normal function of one of the touch-type keys  is altered.

Abstract: Abstract of the Disclosure A method for coloring minced fish meat products wherein a paste-like dye is applied to the edge of an injection opening of a split mold, the mold having a cavity in the form of a cooked-and-peeled meat of a crustacean such as shrimp or crab.  Minced meat of fish or the like is later injected into the cavity through the opening, the dye being moved along the inner surface of the cavity along with and due to the movement of the injected material, and the dye is applied to the inner surface of the cavity and to the surface of the injected minced meat material.  The apparatus for coloring the minced fish meat products is comprised of a mold having a cavity for shaping a food product and an injection opening for injecting minced fish meat material into the cavity.  A food color injection device is provided comprising a pair of nozzles located close to the opening of the mold, the nozzles being capable of free insertion into and retraction from the opening.  A mechanism is also provided for injecting minced fish meat material into the cavity.  The pair of nozzles of the color injection device are made of a flexible material and are flat in section and have, on the end of each, an outward port lacking the outward side.          A head-shaped object is placed between the two nozzles, the object being movable in the direction of the insertion and withdrawal of the nozzles.  A paste-like dye is supplied by the nozzles and is applied to the edge of the injection opening by movement of the object, so that the dye will be applied to the surface of the minced meat material when the minced meat material is injected into the opening.

Title: Nucleic acid probe sandwich assay methods and compositions
Inventor: GINGERAS THOMAS R
IPC: C12Q1/68
Filed: 1987-08-11
Granted: 1992-10-06
Abstract: ABSTRACT                 NUCLEIC ACID PROBE ASSAY METHODS AND COMPOSITIONS          The invention provides nucleic acid probe assay methods, particularly sandwich assay methods, and compositions for use therein. The methods of the invention employ novel, oligonucleotide probe-derivatized solid supports, in which oligonucleotide probe, of 15-100 bases in a sequence complementary to a sequence of nucleic acid analyte, is terminally covalently bound.  The solid supports of the invention are based on beads of amino-, sulfhydryl, or carboxyl-derivatized controlled pore glass, cyanogen bromide-treated cross-linked dextran, or polystyrene.  The linkage between the terminally bound oligonucleotide and the support is effected through these groups, with which the support material is derivatized.  The methods of the invention are based on several unexpected discoveries made in the course of investigating the properties of the novel solid supports of the invention:  (A) There is little difference between carrying out a sandwich assay by (i) simultaneously hybridizing analyte to solid-support-bound probe and labeled probe in solution and (ii) first hybridizing analyte and labeled probe and then hybridizing analyte to solid support-bound probe. (B) The efficiency of capture of analyte is increased by prehybridizing probe-derivatized solid-support with non-homologous nucleic acid or dextran sulfate or both.  (C) The presence of dextran sulfate in a hybridizing solution significant-ly increases the efficiency of capture of analyte by probe-derivatized solid support.  The invention also entails test kits for nucleic acid probe sandwich assays with the solid supports of the invention.

Abstract: ABSTRACT          A  multiple  lumen  catheter is  described  having  a flexible elongate body extending about a longitudinal axis and having a distal end with a tapered tip, a proximal end, an outer wall and a septum extending between spaced points on the outer wall.   The  outer  wall  and the  septum  define  extraction  and return lumens extending from the proximal end to the tapered tip where the outer wall and the septum converge to close off the lumens.  The outer wall also defines respective extraction and return apertures for fluid communication between the lumens and the  tube exterior.   A portion of  the  septum defines  a  third lumen extending along the longitudinal axis of the body from the proximal end to the distal end and terminating at the tip in an aperture.   This  third lumen  is useful  to  receive a Seldinger wire for insertion and can be used also for intravenous infusion of liquid medicaments.        Methods of manufacture are also described.

Abstract: ABSTRACT OF THE INVENTION      A high-voltage  cable  is  fixed  to  the  single  leg of  a  600-amp  "T"  connector,  which  in  turn  is  coupled for non-removable engagement with an insulating bushing fixed to a wall of the apparatus housing it is to serve. A removable screw-applied link member selectively couples the remaining leg to the apparatus bushing whereby power is supplied to the apparatus only when the link is present and  isolates  the  cable when  it  is absent.   A bushing extender and novel  contact extenders  fix the positions of  components  and  serve  to align  the  two arms  of  the link. Each of the arms includes an externally threaded stud  for  engagement  with  the  contact  extenders  which are positioned in the "T" leg and bushing extender such as  to  engage  the  studs  before  interface  interference to assist and guide the screw assembly of such parts. By this system, the apparatus and cable can be tested, grounded and a visible break performed without moving the high-voltage cable.

Patent CA-1303443-C (CA)
Inventor: SCHIERLING ROLAND
IPC: F02M69/10
Filed: 1988-06-08
Granted: 1992-06-16
Abstract: Abstract of the Disclosure The invention is directed to a fuel injection arrangement for two-stroke engines for portable tools such as motor-driven saws.  In known fuel-injecting arrangements, the injection pump is driven by the pressure of the crankcase.  The crankcase pressure increases up to a maximum value which remains constant starting with a predetermined rotational speed up to and including the maximum rotational speed.  When the peak pressure of the crankcase is constant, the stroke of the pump piston of the injection pump is also constant and so is the quantity of fuel which is pumped.  However, at higher speeds where the speed is increasing because of throttling in the air intake channel, the air charge of the cylinder reduces and an overrich mixture is formed.  The fuel injection arrangement of the invention provides for an automatic reduction in the quantity of fuel injected at high and at the highest speeds.  For adapting the required quantity of fuel at high speeds, a counterpressure is developed in the return chamber of the injection pump in dependence upon speed whereby the stroke of the pump piston is reduced.  In this way, a corresponding reduction of the pumped quantity of fuel is achieved.

Abstract: ABSTRACT       A dual cartridge dispenser. Each cartridge has an exit orifice through which fluid is dispensed when a pump portion of the cartridge is compressed. A movable compression member in the dispenser can be located at a first position adjacent the pump portion of the first cartridge or at a second position adjacent the pump portion of the second cartridge. A knob extending outside the dispenser is connected to the compression member for moving the compression member to the first position or to the second position to thereby select the cartridge to be dispensed from. When a movable dispensing member of the dispenser is operated, it causes only the cartridge pump portion that is adjacent the compression member to be compressed between the compression member and an opposed pinch surface in the dispenser thereby dispensing fluid from the cartridge.
