Title: Process and apparatus for the release of a prestress initially applied to a mechanism such as a bearing on board a space vehicle
Inventor: SCHOEFFTER JEAN-PIERRE
IPC: F16C23/00
Filed: 1990-07-11
Abstract: DESCRIPTIVE  ABSTRACT            In space vehicles, mechanisms such as ball bearings (14, 14') are subject to an initial preload or prestress enabling them to with-stand the vibrations caused by the launch and without leading to any clearance or play.  A member (34) made from a shape memory material e.g. makes it possible under the effect of its elongation, to release said preload when the vehicle is in the operational mode.  The con-trol of the release can take place by means of a heating resistor (36), whose energization leads to the member (34) clearing its shape change temperature.     (Fig. 1) SP 5675.69 GP

Title: Diagnostic and amplification methods overcoming a primer-target mismatch at the primer 3' end
Inventor: FINDLAY JOHN B
IPC: C12Q1/68
Filed: 1990-08-31
Abstract: DIAGNOSTIC AND AMPLIFICATION METHODS OVERCOMING  A PRIMER-TARGET MISMATCH AT THE PRIMER 3' END                 Abstract of the Disclosure Methods for amplifying and detecting a predetermined target nucleic acid in a biological specimen are accomplished even where there is a mismatch in a single position between a primer and the target nucleic acid.  The mismatch is located at or near the 3' end of the primer.  Such a mismatch is overcome using a primer having a nucleotide with a thymine base at the position of the mismatch.  The use of such primers is most likely to prime the target and form primer extension products.  This method is particularly useful for detection of a nucleic acid sequence which is not fully known, or where there is considerable heterogeneity in DNA target from patient samples.

Title: Edge triggered d-type flip-flop scan latch cell with recirculation capability
Inventor: CUSHING DAVID E
IPC: H03K3/037
Filed: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE    A  synchronous latch device macrocell which includes an  input  gate  section  and  a scannable latch section. Both  sections are directly connected together to provide a  non-inverting  path  for  input  data  signals thereby eliminating   the  need  for  internal  inverting  buffer circuits.   The non-inverting output of the latch section connects   to   an  output  pin  and  provides  a  signal representation  of  the state  of the latch device.  The output  pin  is  externally connected through a conductor wire  to either one of a pair of complementary data input pins  of  the input gate section.  The connection made is selected   as   a   function  of  which  data  input  pin connection  provides  the  faster  loading  of  the latch device  as  viewed  from the source of the signal applied to the load control pin of the input gate section.

Title: Pretensioned frame
Inventor: VONBENKEN JOHN D
IPC: F02C7/20
Filed: 1991-01-17
Abstract: Abstract An improved lightweight frame for gas turbine engine is disclosed. The frame includes a hub and a radially spaced casing with two rows of circumferentially spaced tie rods extending between the hub and the casing. In a preferred embodiment, jam nuts are provided on the tie rods for accommodating compressive loads therein. The tie rods are pretensioned so that during operation in a gas turbine engine, for example, wherein the tie rods are heated by combustion gases, thermal expansion of the tie rods and resulting compressive stress will be accommodated by the pretension so that in a preferredembodiment the tie rods may operate nearly stress free at normal operation. The two rows of tie rods and jam nut pairs allow the frame to accommodate effectively blade-out loads channeled to the frame 30.

Title: Facsimile apparatus for producing variable size and resolution images on a reproduction medium
Inventor: SHAKLEE KERRY L
IPC: G06T3/40
Filed: 1991-04-29
Abstract: ABSTRACT OF THE DISCLOSURE        A facsimile system which produces variable resolution and size images on a reproduction medium is disclosed.  A timing means produces two signals which control resolution in a first direction.  The first signal controls release of pixels from a memory buffer to modulate the beam intensity of a cathode ray tube while the second signal controls the sweep in the dfirst direction of the electron beam of the CRT.  Resolution and size in a second direction is controlled by repeating lines of image data until the desired resolution is achieved.  Hardware savings in the facsimile can be achieved by connecting a direct memory access controller to a graphics microprocessor through the host post of the graphics microprocessor and by using alternating banks of memory for storage of image data.

Abstract: RECIRCULATING WATER WASHER MEANS AND METHOD A recirculating washer for a paint spray booth is illustrated and described, and uses upward air motion and gravity to recirculate water on and along two or more recirculating baffles facing each other to form one or more curtains of water for cleaning paint laden air from the paint spray booth. The washer's baffles direct the water to form the curtains. The recirculating washer may be used in a booth by itself, or with one or more washers of another type washer, such as a slot type and/or an air nozzlewater nozzle type washer to reduce the amount of water required by the booth. The washer may use the other type washer or a trough for source of the recirculated water. Preferably, the washer utilizes the floor water from the booth so that the water requirement for the entire booth is very low, say on the order of 40 gallons per minute per foot of booth length, or less, for a booth of a size capable of production line painting of automotive vehicles.
