Title: Cuvette for the optical examination of fluids
IPC: G01N21/03
Filed: 1980-05-23
Abstract: A cuvette for holding a liquid to be examined optically has front, back, and side walls defining a rectangular cross section and a Y-shaped structure at the bottom thereof for holding the liquid. The Y-shaped structure extends between transparent front and back walls with an upper funnel mouth extending to the side walls, and a liquid holding portion formed of inner walls spaced between the side walls, and extending down to a rounded, tub-shaped bottom. The front walls are transparent and serve also to form the front and back of the liquid holding portion. The bottom preferably has a frustroconic surface to minimize the amount of liquid required for examination and to facilitate mixing of liquids added to the cuvette. The side walls extend below the tub-shaped bottom, and are joined to the front and back wall midway up the liquid holding portion by means of a rib, so that light is not scattered by the side walls and optical inhomogeneities are prevented.
Patent EP-0030741-A3 (EP)
Title: Longitudinal isolation system for flexually vibrating force transducers
IPC: G01L1/10
Filed: 1980-12-17
Abstract: A system for isolating the mounting pads of a vibrating beam ortuning fork force transducers from longitudinal vibrations generated by transverse vibrations of the beam or tuning fork tines (50) which extend between the mounting pads (56). The system includes an arrangement of longitudinally resilient support links (58) and masses (54) that flex responsive to change in the length of the beam or tines (5) as the beam or tines (50) vibrate transversely. The support links (58) and masses (54) thus isolate the mounting pads (56) from the longitudinal vibrations of the beam or tuning fork tines (50) while allowing transmission of forces applied between the mounting pads (56) which vary the force dependent resonant frequency of the beam ortuning fork (50).

mehrere hintereinandergeschaltet werden müssen, wird 
vorgeschlagen, die Ausgangsstoffe in wäßriger Suspension 
einer Solventextraktion zuzuführen und anschließend die 
Metalle in einem Reextraktionsprozeß selektiv zu gewinnen.
Patent EP-0052368-A3 (EP)
Title: Bumperless gun nailer
IPC: B25C1/04
Filed: 1981-11-16
Abstract: A fastener applying tool driven by air in a driving stroke and a return stroke featuring noise and recoil reduction and increased efficiency, driving force, and speed of operation. Air directed into the main cylinder to force the main piston through its driving stroke is stored in a chamber to rapidly return the main piston. Air compressed by the main piston at one end of the main cylinder is used to form an air cushion to keep the main piston from striking the bottom of the cylinder. The main piston cycles within a slidably mounted main cylinder. Pressurization of one end of the main cylinder during the driving stroke repositions the main cylinder to close the main valve to shut off high pressure air from the main piston and open a valve to vent the air above the piston to atmosphere. Upward movement of the cylinder and rapid return of the piston significantly reduces the recoil force normally experienced in such a tool. A valve assembly coaxially located at the opposite end of the main cylinder functions to admit and exhaust air to pressurize and vents the piston and main cylinder respectively. Noise suppression is achieved by an elastomeric cap. Rapid acting components reduce air wastage and improve overall tool efficiency.

Abstract: A weight-case (10) of a synthetic resin material contains 
a weight (20) of a metallic plate together with the bottom part 
(81) of a slat-cloth (80) and includes as one body a top guide 
(30) for guiding the slat-cloth to turn about and let in the

Abstract: Method and means for solidifying nuclear waste 
for permanent disposal are disclosed. A storage con­
tainer, in the preferred form of a drum or barrel (28), 
is charged with a predetermined amount of liquid poly­
mer resin (119) in an uncatalyzed state. Catalyst-con­
taining frangible ampoules (131) are also positioned in 
the drum with a rotatable mixer mechanism (65). At 
a waste filling station (26), the mixer is rotated to break 
the ampoules so as to mix the catalyst and the resin. 
The catalyzed resin is then mixed with added waste 
material from a feed (33) to completely encapsulate 
the waste prior to solidification of the resin. Monitoring 
of the filling and mixing process is provided by con­
tinually sensing the torque force being applied to the 
rotating mixer mechanism. Where the waste 
is a dustlike, dry particulate material, dust control means 
and method are also provided.

Abstract: In order to provide improved flexibility of operation 
consistent with small size, low mass and low inertia, a 
self-propelled drawing device 2 or 3 is driven by two 
independent wheels 12 whose axes are fixed, and has a 
writing tip 17 which marks the drawing medium 1 at a point 
which is not on the imaginary line joining the points of 
contact of the wheels with the drawing medium. In order to 
provide a simple umbilical cord which is less likely to impede 
the movement of the drawing device, the drawing device is 
connected to a stationary control device 5 by flexible 
conductors in the form of a ribbon 4 whose width lies in a 
vertical plane. Instead of a drawing device, the device can be 
arranged as a tracing device with counters on the wheels and 
a tracing tip instead of the writing tip.

Abstract: The frame synchronizing system for a muliplex trans­
mission system comprises a center unit (1) and a plurality of 
terminal units (3,4,5). They are interconnected through up 
and down dual bus transmission lines (R,T). Communica­
tions between the center unit (1) and each terminal unit 
(3,4,5) or between the terminal units (3,4,5) are performed on 
the time division basis. The frame synchronising system 
comprises a bus terminator (2), too. It is provided across 
terminal ends of the bus transmission lines (R,T). The bus 
terminator (2) returns a frame synchronizing-bit having a 
plurality of bits on the down transmission line (R) to the up 
transmission line (T). Each terminal unit (3,4,5) performs 
frame synchronization in accordance with the returned frame 
bit to send a signal to the up transmission line (T) at a phase 
subject to the phase synchronization. With this system, bit 
overlap between channels of respective terminal units can be 
eliminated to ensure accurate transmission.

Abstract: Guide tube alignment pins are secured to a flange at the 
lower end of a guide tube of a nuclear power plant reactor ves­
sel. They extend downwardly from the flange and enter open­
ings in an upper core plate of a guide tube assembly as the guide 
tube is lowered into place to align the center of the guide tube 
with the center of the fuel bundle or fuel element so that the 
cluster control rod in the guide tube can enter the fuel bundle 
with the least amount of drag and in the proper time. The guide 
tube alignment pins include guide fingers at the lower portions 
thereof which enter the openings in the upper core plate for 
positioning the center of the guide tube over the center of the 
associated fuel bundle or fuel element. Intermediate the ends 
thereof, the guide tube alignment pins are formed with a Morse 
taper to increase the width of the shanks at the areas subject 
to frequent fractures. A locking device at the top of the guide 
tube alignment pins, which is integrally formed with a locking 
cup, is crimped for securement of the upper ends of the guide 
tube alignment pins to the flange at the lower end of the guide 
tube.  
     Guide tube alignment pins have been made of Ni-Cr-Fe al­
loy X-750. To reduce stress corrosion cracking of the guide 
tube alignment pins, the guide tube alignment pins are heat 
treated by solution annealing at 2000°F ± 50°F for a mini­
mum of one hour and then cooling to ambient temperature. 
This procedure is followed by heating the guide tube alignment 
pins at 1300°F ± 50°F for approximately twenty hours and 
then cooling to ambient temperature.
