Title: Low profile inker
Inventor: NADEAU NORMAND
IPC: B43L13/02
Filed: 1988-06-24
Granted: 1992-06-23
Abstract: ABSTRACT             A low profile inker for use in a semiconductor testing apparatus.  A probe test head of the apparatus detects defective circuits on a semiconductor wafer and generates control signals in response thereto.  The inker is connected to the testing apparatus by means of a support arm beneath the probe test head.  An inker reservoir is connected to the support arm and has a substantially vertical needle extending therefrom with a tip thereof proximate the semiconductor wafer circuit under test. A solenoid activated plunger arm is connected to the support arm in parallel with the reservoir and an angle pin connects the plunger to an inker filament disposed within the reservoir.  The angle pin converts vertical movement of the solenoid operated plunger into parallel movement of the inker filament within the reservoir for forcing liquid onto the semiconductor wafer in order to mark defective circuits.

Abstract: FRONT LOADING CLEANING MACHINE                ABSTRACT OF THE DISCLOSURE     A front loading cleaning machine may be operated in a normal manner by opening the front door and loading clothes to be washed.  When servicing is required, the entire unit may be tipped forwardly about 90 degrees so that the front door is next to the floor.  This makes the rear of the machine unit upper-most and exposes the drive mechanism mounted thereon. The drive mechanism may then be readily serviced because the mechanically moving parts are exposed on the upper portion of this machine unit.  After servic-ing,  the machine may readily be tipped back to its upright position, ready for normal operation. The foregoing abstract is merely a resume of one general application,  is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Title: Connector assembly having a latching mechanism
Inventor: MYERS CLYDE J
IPC: G02B6/36
Filed: 1989-04-17
Granted: 1993-02-23
Abstract: Abstract A connector body (26) which terminates at least one transmission medium includes on each side thereof a cantilevered arm (66) having a latching nub (70) projecting from a free end of the arm. A release cover (80) having a gripping portion (88) oriented toward a cable input end (32) of the connector body is mounted slidably on the connector body with the latching nubs of the arms each projecting through a window (90) in the cover. Conductors in the connector body are connected to conductors of another connector or of a device by inserting the connector body and release cover into a coupling (100) or into a receptacle. The latching nubs of the arms protrude into openings (106-106) provided in a housing (102) of the coupling to secure the connector body thereto. In order to withdraw the connector body from the coupling, a user moves the cover slidably along the connector body toward the cable input end. Walls which define the windows of the cover cam against the latching nubs causing them to be depressed as the free ends of the arms are moved inwardly. Once the nubs have cleared the openings in the coupling or in the receptacle, the connector body and release cover may be withdrawn from the housing. The release cover also is effective when forces of a predetermined magnitude are applied to the connector body to cause the latching nubs to become disengaged from the coupling and allow withdrawal of the connector body therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE      An input gray-scale image is converted to a bilevel output signal by an image-processing apparatus with two binarizing circuits:  one employing a uniform threshold and the other a dither matrix.  The outputs of these circuits are selected for each pixel by deciding whether the pixel is a bilevel pixel or a gray-scale pixel.  The decision is based on the maximum and minimum gray levels in a block of pixels centered on the pixel in question.  Images having both bilevel and gray-scale parts can thus be binarized with clean reproduction of black-white edges.

Title: Recombination resistant retroviral helper cell and products produced thereby
Inventor: TEMIN HOWARD M
IPC: C12N7/04
Filed: 1989-06-13
Granted: 1994-05-17
Abstract: Abstract An improved helper cell for growing up stocks of replication incompetent retrovirus vectors is disclosed. The helper cell resists recombination events due to the fact that natural promoters and poly(A) sequences in the helper sequences have been replaced with foreign promoters and poly(A) sequences bearing little or no homology to the vectors. Plasmids containing these modified sequences can still create a helper cell with resulting expression of the needed helper proteins, yet there is much less risk of recombination events in the helper cell. Also disclosed are vectors produced by such helper cells, target cells infected by such vectors, and helper cells which convert vectors so that they can be used with hosts from different species.

Title: Group control for lifts with immediate allocation of target cells
Inventor: FRIEDLI PAUL
IPC: B66B1/20
Filed: 1989-07-13
Granted: 1993-04-06
Abstract: Abstract of the disclosure In this group control, a call, which is to be allocated to a cage for the first time, is allocated immediately and finally after its input.          For this purpose, operating costs corresponding to the waiting times of passengers are computed merely for the input storey and the target storey of the new call from data specific to the lift and transferred into a cost register  (R1)  for all  lifts  immediately  after the  input of the call. Thereafter, the comparison of these operating costs takes place at once, wherein  the  call  is finally allocated  to  the  lift with  the  smallest operating costs.  The operating costs computation extends over all traffic participants situated in the cages and on the storeys, wherein the computer utilises  a travelling time  table  (15),  in  which  the  travelling  times between a certain storey and every other storey are stored.   The door opening and closing times of the lift concerned are stored in a door time table (14), which times the computer utilises for the computation of the stopping time of the cage.  By the operating costs computed in that manner, better comparison results are achieved and exact data on the actual waiting times of all traffic participants are put at disposal.
