Title: Nulling optical bridge for contactless measurement of changes in reflectivity and/or transmissivity
IPC: G01N21/35
Filed: 1988-09-12
Abstract: A nulling optical bridge is disclosed herein for the 
measurement of the difference in the relative power of 
more than one light beam. The bridge can be used to 
precisely measure the change in reflectivity and/or 
transmissivity of a semiconductor device or metal. The 
bridge operates by splitting at least one illumination 
source into a number of beams (A; B) wherein one of 
said beams (B) is made to traverse the sample whose 
change in transmissivity and reflection characteris­
tics is to be measured. A rotating polarizer (2) is 
used to equate the intensity of the variable and 
nonvariable beams under feedback servo control from a 
photodetector. The incremental quantity of rotation of 
the polarizer can be calibrated to correspond to a 
number of characteristics of the sample.

Title: Shaft for a prosthesis
IPC: A61F2/30
Filed: 1989-04-05
Abstract: In order to anchor a prosthesis in a bone using a bone cement (32), the prosthesis shaft has a surface which is made up of the surfaces of several balls (23...25) partially penetrating through one another and with a radius decreasing from the proximal end to the distal end of the shaft. The transitions between each of the adjacent ball surfaces (23...25) are rounded in a concave manner. Such a design is particularly suitable when using glass ionomer bone cement, since it is essentially only compressive stresses which are exerted on the cement by the shaft, whereas tensile and notch stresses, to which this type of cement has little resistance, are substantially avoided.

integrated gate array semiconductor device, each of which is 
identical. Each memory logic array is provided with a base address 
input (46) from a preceding memory logic array and computes a base 
address for a subsequent memory logic array. A memory logic array 
which has a portion of an associated memory disabled automatically 
determines a revised base address for the subsequent memory logic 
array, thereby initiating the automatic reallocation of memory board 
base addresses of all subsequent memory boards.

Filed: 1989-07-21
Abstract: A sheet feeder (10) has a supply station (16) wherein signatures 
fresh from the printing press are stacked. The stack is 
supported such that the signatures are in an arched, non-planar 
configuration. A sheet stripper (18) extracts signatures successively 
from the stack and feeds them in a constant stream to a transfer 
conveyor (20). The stripper grips the sheets with a suction device 
which applies a constant but locally intermittent vacuum. The 
transfer conveyor carries the signatures to a delivery station (22). 
The delivery station includes fingers (116) which arch the signatures. 
Arching the signatures in the supply and delivery stations 
prevents rolling of the signatures.

Title: Three-roll thickener for pulp and paper stock, and use thereof
IPC: B03B5/48
Filed: 1989-10-19
Abstract: Apparatus and method for thickening a 
suspension of pulp in liquid employs three rolls (20, 
22, 25) arranged in spaced relation with their axes 
defining a triangle, and a single loop of wire (30) is 
trained around and in wrapping relation with all three 
rolls. The first and third roll have a headbox (40, 45) 
which delivers a flow of the suspension to be thickened 
in such manner that it is trapped between the wire and 
the portion of the roll wrapped by the wire so that the 
trapped suspension is dewatered and concentrated by 
expression of liquid through the wire. The pulp 
deposited on the inside of the wire at each of the 
positions comprising a roll and headbox is collected 
from the surface of the second roll (22) and is 
transported out from within the triangular space within 
the wire loop. In one embodiment, the roll at each 
roll-headbox station has a grooved surface such that it 
forms separate strips of pulp on the wire, and the next 
roll downstream therefrom has a similar grooved surface 
offset axially from the preceding roll so that it causes 
strips of pulp to be deposited on the wire between the 
strips produced by the previous roll.

Title: Adjustable video/raster phasing for horizontal deflection system
IPC: H04N3/227
Filed: 1991-03-22
Abstract: Adjustment and maintenance of a phase relationship between a video signal (on 11) and a scan synchronizing signal (on 67) to assure proper horizontal centering is provided in a horizontal deflection system (40). A first phase locked loop generates a first timing signal (on 17) at a first frequency, synchronously with a horizontal synchronizing component in a video signal. A presettable counting circuit (in 56) operates synchronously with the first timing signal for dividing a clock signal to generate a second timing signal (on 61) at a second frequency. A second phase locked loop (62) generates a scan synchronizing signal (on 67) from the second timing signal. A microprocessor (74) may supply different numbers to a register (in 56), the output of the register being coupled to the presettable counting circuit. Different numbers (from 74) change the relative phase between the first and second timing signals by incremental steps. The microprocessor (74) monitors a video source selection switch to gate one of alternative video sources as a video and synchronizing signal output and adjusts the relative phase between the horizontal synchronizing component of the selected video source and a synchronous timing signal by a factor appropriate for the selected video source. A manually operable circuit (72) may be coupled in a feedback path of the second phase locked loop (62) for adjusting the relative phase between the second timing signal (on 61) and the scan synchronizing signal (on 67), over a range corresponding to an incremental step. <IMAGE>
