Title: Method for the polymerization rotation casting of lenses and equipment for performing this method
IPC: B29L11/00
Filed: 1989-05-12
Abstract: The solution pertains to a method for the polymeriz­
ation rotation casting of lenses and to an equipment 
for performing this method.  
     The method for the polymerization rotation casting of 
lenses according to the present invention comprises a 
convex and concave surface in molds (13) being placed 
in a rotation mechanism, where the convex surface of 
the lens is formed by the rotation of a liquid having a 
higher specific weight than that of monomer mixture and 
is immiscible with said monomer mixture and also with 
its individual components, wherein the concave surface 
of the lens is formed by a convex surface of the mold 
(13) while the remaining space of said mold is filled 
with said liquid having a higher specific weight.  
     The method for the rotation casting according to this 
invention may be carried out both in a column arrange­
ment of molds and in single separate mold.  
     An equipment for the column arrangement consists of a 
calibrated tube closed at the lower end and provided 
with a one-way valve for the inlet of specifically 
heavier liquid, in which the molds, provided with 
 
 
channels connecting the spaces above and below mold 
bottom, are arranged in a column, whereas the cali­
brated tube (1), which is carried above and below in 
ball bearings, passes through a pulley (11) for ver­
tical rotation and is placed in the horizontal 
direction in a rotary pivot (12) for turning the tube 
(1) around its horizontal axis and tilting it from the 
vertical direction during rotation.  
     The equipment for performing the method of rotation 
casting in individual separate mold, for example, in a 
carrousel, consists of a mold (13), on the convex side 
of which is set a cap (19) filled with the specifically 
heavier liquid and provided with a puncture closure 
(20) for dosing of monomer mixture, whereas the mold is 
mounted on a rotary pin (21).

Title: Power tool
IPC: B25F5/00
Filed: 1989-08-14
Abstract: A portable power tool including a body in which a bore 
(4) is formed and a piston (3 ) is slidable within the bore. A 
combustion chamber (2) is formed in the body and is in 
communication with the bore. The combustion chamber (2) is 
arranged to receive a gaseous fuel from a source (5). An 
inlet port (6) into the chamber (2) and an outlet port (12) 
therefrom are controlled by a valve means (10). Preferably 
the arrangement is such that fuel entering the chamber through 
port (6) scours the chamber (2) of residual gases through port 
(12). The tool preferably has various additional features 
such as means for monitoring the valve means in an open 
condition for a preselected time. That means may include a 
detent catch (39), and an actuating membrane (32). A 
lubrication system (94) may be provided for lubricating the 
valve means. A fuel deflecting vane (80) may be mounted in 
the combustion chamber to improve turbulence therein. Also, 
the piston may have a vacuum detent arrangement (75) for 
holding the piston towards the combustion chamber (71) during 
the initial stages of combustion in the chamber.
Patent EP-0356259-A3 (EP)
IPC: G21C17/003
Filed: 1989-08-25
Abstract: In a hydraulic system of a control rod drive 
(D) for insertion of control rods (C), a test apparatus 
and test process is disclosed for determining the 
integrity of the hydraulic system check valve (22) for 
preventing inadvertent control rod ejection responsive 
to the reactor pressure. The check valve is located 
between a hydraulic valve (18) for causing rod 
insertion and a hydraulic cylinder containing an 
actuating piston (P). Downstream of the check valve, 
alteration is made to the hydraulic path by the 
installation of a conduit (40) with a quick disconnect 
(44,84) connected through an isolation valve (42). 
Test apparatus for temporary connection at the 
disconnect is disclosed consisting of a small positive 
displacement piston and cylinder (60) which connects to 
the quick disconnect through a rapidly opening toggle 
valve (71). Provision is made for timing the excursion 
of piston in the piston and cylinder preferably by end 
of stroke microswitches (66,74). When the quick 
opening valve (71) is opened, with resultant backflow 
from the hydraulic system through the check valve into 
the volume defined by the small displacement piston and 
cylinder (60), proper check valve operation and closure 
results in a long excursion time of the piston between 
the two microswitches: this indicates that the check 
valve seats and remains sealed to prevent control rod 
ejection. Control rod ejection is not permitted due to 
the small volume of the interrogating piston and 
cylinder. If the time of excursion of the piston 
between the two microswitches is short, there is an 
indication that the check valve has not properly seated 
and that control rod ejection is possible.

exhibit low heavy metal contamination and fewer defective 
coatings following compact fabrication using a hardenable 
binder including petroleum pitch or the like. Nuclear 
fuel particles having a multiple layer fission-product-­
retentive barrier, with a dense outer layer thereof being 
surrounded by a protective overcoating, e.g., pyrocarbon 
having a density between about l and 1.2 g/cm³, that is 
encapsulated within a thin shell of pyrocarbon from about 
1.7 to about 2 g/cm³ in density, can be precisely 
metered to create charges containing very precise amounts 
of nuclear fuel material that can be pre-compacted in 
molds under relatively high pressures and then combined 
with the fluid binder which is ultimately carbonized to 
produce carbonaceous compacts containing very precise 
nuclear fuel loadings.

Title: Polypectome snare with bipolar electrodes
IPC: A61B18/14
Filed: 1989-12-04
Abstract: A polypectome snare whose loop (46) comprises a pair of electrodes 
(40,42) mechanically joined but electrically insulated from 
one another at their distal ends and adapted to be energized by a 
source of RF voltage for excising polyps on the inside of a body 
cavity is described. The polypectome snare is designed to be 
used with an endoscope and includes two concentric flexible 
plastic tubes (12,20) each having proximal and distal ends (14) and a 
lumen running the length thereof. At the proximal end is a hand grip 
which is secured to the wires leading to the bipolar electrodes 
with one of the wires passing through the lumen of the outermost 
tube and the other wire extending through the lumen of the inner 
tube. In this fashion, the wires remain insulated from one 
another over the length of the instrument and due to this same 
arrangement, the conductors comprising the bipolar electrodes 
cannot become twisted at the distal end of the implement to 
thereby create a short which would render the snare inoperative.

Patent EP-0679801-A3 (EP)
Inventor: OKAMOTO AKIO
IPC: F02D31/00
Filed: 1995-04-25
Abstract: The idle speed control device according to the
present invention controls a two-solenoid rotary type idle
speed control valve properly even when one of the
solenoids fails. When one of the solenoids fails, the
device calculates the amount of bypass air from the amount
of inlet air and the degree of opening of the throttle
valve, and estimates the degree of opening of the idle
speed control valve. If the degree of opening of the
bypass valve is larger than that of the neutral valve
position, the device sets the duty ratio of the control
signal for driving the idle speed control valve at 0 %,
and if the degree of opening of the idle speed control
valve is less than that of the neutral valve position, the
device sets the duty ratio of the control signal at 100 %.
By this control, the two-solenoid rotary type idle speed
control valve is maintained at neutral valve position
without determining the type of the failure of the
solenoids precisely.

Patent EP-0680932-A3 (EP)
Inventor: TURNER ANDREW DEREK
IPC: C02F1/461
Filed: 1995-04-26
Abstract: An electrochemical cell (50) for deionisation
utilises electrochemical ion-exchange to remove ions from
a feed solution. Under the influence of an electric
field, ions are adsorbed into, are stored within and pass
through a permeable layer (54, 64) of particulate ion-absorbing
material and binder, the sheet being several
millimetres thick. Water from the feed solution also
permeates through the layer (54, 64), so a concentrated
solution of the ions emerges from the rear (58) of the
layer. The cell does not require separate sources of
feed and eluant solutions and can be operated
substantially continuously. In a modified cell (70) the
flow path for the feed solution passes through a highly
porous ion exchanger structure (77), which may be located
between two such microporous layers (54, 64). Absorption
in such a cell may be effective in the absence of an
electric field, elution requiring the periodic
application of the electric field.
