Patent EP-0163291-A3 (EP)
IPC: G01N23/227
Filed: 1985-05-28
Abstract: An instrument for monitoring the surface characteristics 
of materials, whereby the surface is characterized by 
measurement of a current of photoemitted electrons flowing 
from the surface to a collector on the instrument. The 
instrument directs ultra violet light against the surface being 
measured, and the photoelectrons emitted are characteristic 
of surface features such as oxide thickness, contamination, 
or fatigue. The current of electrons emitted from the surface 
is compared with previously established limits for surface 
quality to provide an acceptability test of the surface. The 
instrument is portable and does not require the use of a 
vacuum chamber.

Patent EP-0186278-A3 (EP)
Title: Detecting defects in transparent articles
IPC: B07C5/34
Filed: 1985-10-24
Abstract: An apparatus and method for detecting sidewall and dimensional defects in transparent containers includes a laser scanning system (40, 42, 44) positioned astride a conveyor (12) in a production line. In an upstream inspection zone a laser beam vertically scans a portion of the side wall of the container. Photosensors (62, 64, 66, 68) positioned in a detection chamber (56) detect the specific effect which any defect has upon the laser beam by determining the location of light passing through the container and comparing its intensity against pre-set thresholds. A flaw signal is generated when a threshold is exceeded. The number of flaw signals is counted (78) and when the count equals a pre-set value a reject signal is generated (98) to eject the defective container from the conveyor. If a container is not rejected, is passes through a rotator assembly which rotates the container precisely 90 DEG . The container then continues to a similar downstream inspection zone where an indentical scanning and detection process is repeated with regard to the previously uninspected portions of the side wall of the container.

Abstract: Disclosed herein is a multiple component hip 
femoral prosthesis system having a stem component (11) for 
intramedullary implantation in a truncated femur, a neck 
component (12) connected to the stem component (11) by means of a stud (18) 
projecting from one of the components and mating with a 
recess (20) provided in the other for reciprocating movement 
therein, a rigid calcar collar (14) slideably positioned on the 
stud (18) and designed to overlie the cut end of the bone 
including at least a substantial portion of the calcar (14), a 
cushioning body (15) of elastomeric material such as silicone 
rubber interposed between the calcar collar (14) and a shoulder (19) on 
the neck component (12), and a ball-shaped femoral head (13) preferably 
detachably mounted on the upper end of the neck component (12) for 
articulation with the acetabulum or an acetabular prosthesis. 
The stud (18) is enabled to slide up and down in the mating recess (20) 
as stresses are applied and relieved. The cushioning body (15) 
absorbs shock and causes forces to be substantially evenly 
distributed over the calcar collar (14) which in turn distributes 
forces over a large bone area to prevent localized stresses 
and bone resorption and the stem (11) is effectively isolated from 
shock forces.

Title: Command and control device for a tool
IPC: G05D17/00
Filed: 1987-02-27
Abstract: A control and monitoring arrangement for "intelligent" tools is disclosed each of which is preset with a reference value for at least one assembly parameter for each assembly operation by a control unit, and each of which signals the actual value measured by means of incorporated sensors in respect of said assembly parameter to the control unit which compares that measured value to the reference value.

Each of the tools can be used without particular operating steps, in a freely selectible sequence, for different assembly tasks at different assembly locations. The arrangement has a recognition means which, for each assembly location at which an assembly task is to be carried out, generates a recognition signal for identifying the assembly location and/or the tool, when the tool moves into the area of the assembly location, the recognition signal being transmitted to the control unit and there serving to select the at least one reference value which is desired for the respective assembly task in question and/or the associated tolerance limits.

Patent EP-0289113-A3 (EP)
IPC: G01G23/06
Filed: 1988-02-26
Abstract: The weighing apparatus according to the invention 
is for use on a support surface which is subject to 
vibration. The apparatus includes a base adapted to be 
positioned on the support surface and having opposing first 
and second sides. The base is adapted to transmit 
vibrations from the support surface. A tray holds the 
product to be weighed and has a center of gravity adjacent 
the first side of the base. A load cell supports the tray 
on the base at the first side of the base. Strain gauges 
connected to the load cell generate a signal indicative of 
the weight of the tray and any product held thereby. The 
signal includes oscillating noise corresponding to 
vibrations transmitted by the base through the load cell to 
the tray. An auxiliary beam and counterbalance weight 
stablize the tray by minimizing at least some of the 
vibrations transmitted to the tray and by converting at 
least some of the lower frequency vibrations transmitted to 
the tray into vibrations having a frequency which is higher 
than the frequency of the lower frequency vibrations. The 
tray transmits reverse-phase vibrations to the load cell 
which result in noise in the signal. The auxiliary beam 
and counterbalance converts at least some of the 
reverse-phase vibrations transmitted to the load cell into 
vibrations having a frequency which is higher than the 
frequency of the reverse-phase vibrations.
