Title: Steerable axle assembly with preloaded kingpin drawkeys
Inventor: SHEALY NOAH A
IPC: F16B3/00
Filed: 1990-03-19
Abstract: ABSTRACT                              Title STEERABLE AXLE ASSEMBLY WITH  PRELOADED KINGPIN DRAWKEYS    A steerable axle assembly incorporates an improved kingpin securement system for accommodating wear during the useful life of the kingpin.  The assembly defines a steering axle boss having a  vertically  oriented  bore.   A pivotal  steering knuckle  is secured to the boss.  A cylindrical kingpin is supported within the bore and extends through apertures in the knuckle to retain the knuckle on the boss.   The boss includes a cross aperture which extends transversely to and partially intersects the bore.          A drawkey,  supported within the cross  aperture,  includes  an elongated head having a tapered flat surface adapted to engage the kingpin. The drawkey includes a threaded shaft portion which has an end extending externally of the cross aperture, and a nut threaded on the shaft portion  for securement of drawkey the against the kingpin.  A disc spring washer is secured about the threaded shaft portion of the drawkey, between the nut and an exterior surface of the boss for preloading the drawkey against the kingpin.   In a preferred form, the taper on the drawkey is within  a  range  of  5-10  degrees,  while  the  preferred  load deflection  accommodated  by  the  disc  spring washers  is approximately 30 thousandths of an inch.

Title: Load-dependent brake valve for controlling the brake line pressure of compressed air brakes of a vehicle
Inventor: THONY RIET
IPC: B60T8/18
Filed: 1990-05-10
Abstract: INVENTOR:   RIET TH?NY             INVENTION:  LOAD-DEPENDENT BRAKE VALVE FOR CONTROLLING THE             BRAKE LINE PRESSURE OF COMPRESSED AIR BRAKES OF A VEHICLE     ABSTRACT OF THE DISCLOSURE  In load-dependent brake valves it is customary to control the brake force as a function of the stroke of vehicular suspension springs.  If the stroke of the vehicular suspension springs is not proportional to the vehicle load, there is the risk that either the empty vehicle or the full vehicle is too strongly braked.  This can be avoided in that a pivotable brake lever is pivotable as a function of the stroke of the vehicular suspension springs, the pivotable brake lever comprising a first pivoting range  in which a first edge of a piston of the load-dependent brake valve is supported and a second pivoting range in which a second edge of the aforesaid piston is supported.  It is thereby achieved that the brake force is always proportional to the vehicle load.

Patent CA-2023888-A1 (CA)
Inventor: SIMONS MALCOLM J
IPC: C12Q1/68
Filed: 1990-08-23
Abstract: The present invention provides a method for detection of at least one allele of a genetic locus and can be used to provide direct determination of the haplotype. The method comprises amplifying genomic DNA with a primer pair that spans an intron sequence and defines a DNA sequence in genetic linkage with an allele to be detected. The primer-defined DNA sequence contains a sufficient number of intron sequence nucleotides to characterize the allele. Genomic DNA is amplified to produce an amplified DNA sequence characteristic of the allele. The amplified DNA sequence is analyzed to detect the presence of a genetic variation in the amplified DNA sequence such as a change in the length of the sequence, gain or loss of a restriction site or substitution of a nucleotide. The variation is characteristic of the allele to be detected and can be used to detect remote alleles. Kits comprising one or more of the reagents used in the method are also described.

Title: Dielectrophoretic characterisation of micro-organisms and other particles
Inventor: BETTS WALTER B
IPC: B03C5/02
Filed: 1990-11-27
Abstract: Dielectrophoretic collection rates of microorganisms or other animate or inanimate dielectrically polarisable particles in suspen-sion in a fluid are established by flowing the suspension past electrodes (17, 18) energised to produce a non-uniform alternating electric field in the suspension, terminating the energi-sation of the electrodes after a predetermined time to release particles collected from the su-spension, and, downstream of the electrodes, measuring the pulse of released particles as a measure of the rate of particle collection dur-ing energisation of the electrodes. Repeated measurements at different field frequencies enable a collection-rate spectrum to be esta-blished and the particles under examination to be characterised or identified by reference to known spectra of known particles.

Title: Power outlet for electrical accessories
Inventor: EL-HAJ ALI
IPC: H01R24/58
Filed: 1991-08-26
Abstract: An electrical power outlet assembly having a socket formed by a one-piece, deep-drawn metal cup with an inte-gral out-turned flange at its mouth, the cup having at its bottom a transverse end wall that is lanced to form a diametric, spade-like terminal piece. One end of the terminal piece is integral with the metal cup, and the other end is free and clear. The terminal piece is bent outward to form an outstanding spade connector. An insu-lacing terminal block is carried in the metal cup, and has a through passage extending from its front to its rear. An electrically conductive terminal is carried by the block and extends completely through the passage.      The terminal has a forward contact portion adjacent the front of the block, and a rear terminal portion extend-ing from the rear thereof. The advantage of the present invention is that an especially simple and inexpensive, one-piece socket construction is realizeable by virtue of the integrally formed terminal piece that is stamped from the bottom wall of the metal cup.
