Title: Mould exchanging apparatus for a plastic injection moulding machine
IPC: B29C45/17
Filed: 1987-03-23
Abstract: The mould exchanging apparatus, serving a plurality of plastic injection moulding machines, comprises an exchanging table (27), which serves as transporting carriage and can be moved in a linear guide (45) to a depot (44) for injection moulds as well as to the plastic injection moulding machines, aligned in parallel with the guide (45), in connecting position for the mould change. Two mould receiving places are arranged one behind the other on a rotatable carrier plate (27h) on the exchanging table (27). In the connecting positions, mould guides (G") of the receiving places, with the carrier plate (27b) turned if need be, form alternately with a mould guide of the mould clamping space of a plastic injection moulding machine and alternately with a mould guide of a depot receiving place (44a) transport tracks for the exchanging of an injection mould. It is achieved by such a design that the injection moulds of an entire group of plastic injection moulding machines can be exchanged fully automatically with the exchanging table (27), provided that the said machines are arranged in a space-saving manner with respect to the mould depot (44). This arrangement avoids running over the operator sides of the plastic injection moulding machines, and consequently the operator, following an upright transporter. <IMAGE>

Patent EP-0267554-A3 (EP)
IPC: C08G59/32
Filed: 1987-11-06
Abstract: The present invention provides a stable, 
aqueous dispersion of a polymer characterized by an 
average molecular weight of at least 50,000 and 
comprising the reaction product of from 10 to 90% of 
a monomer containing ethylenic unsaturation and 
pendent cationic reactive functionality, and 90 to 
10% of a monomer containing ethylenic functionality, 
said polymer having cationic functionality sufficient 
to undergo self-crosslinking through said cationic 
reactive functionality in the presence of a cationic 
photo-initiator and upon exposure to actinic light to 
become insoluble and infusible. Said polymer is also 
combined with a cationic photo-initiator to provide 
for a polymer system crosslinking upon exposure to 
actinic light to provide an infusible and insoluble 
material incorporated in coating compositions which 
when applied to a substrate and dried are cured with 
ultraviolet light to provide durable protective 
coatings.

Title: Magnetic purification of slurries
IPC: B03C1/032
Filed: 1987-08-27
Abstract: A process which is especially useful for effecting magnetic separation of magnetically attractable impurities from an aqueous clay slurry or suspension includes passing the suspension (42) through a porous, ferromagnetic matrix while applying a magnetic field to the matrix (10), on which impurities are collected, and thereafter regenerating the matrix by flushing collected impurities therefrom with a flush liquid (26), e.g. water. The improvement comprises, after discontinuing the passage of the suspension through the matrix, but before passing flush liquid therethrough, admitting a pressurized gas (68) e.g. compressed air, into the separator to displace suspension retained therein, and recovering the displaced suspension. In addition, flush liquid retained in the matrix after the flushing step may be displaced therefrom by the compressed air. By displacing the retained suspension from the matrix with compressed gas instead of flush liquid the retained suspension is not diluted and is recovered instead of sewered as in the prior art processes.

Title: Laser interferometer-refractometer
IPC: G01N21/45
Filed: 1988-01-13
Abstract: A laser interferometer-refractometer for measuring the refractive index of a gas has a laser (1), at least one beam splitter (10) for splitting up the laser light beam into at least one pair of component beams (20, 20'), an evacuable cell (25) which forms the vacuum travel path of a total travel path, formed from a travel path in the vacuum and a travel path in the gas to be measured, of a component beam (20) of the pair of component beams, and at least two beam deflectors (8, 9), which unify the component beams (20, 20') and are intended to generate interferences between the component beams. The optical path length of one component beam (20) can be adjusted for the purpose of enhancing the measurement accuracy. One wall (5), which is situated in the travel path of the component beam (20) and delimits the vacuum space of the cell (25), is constructed displaceably in order to adjust the optical path length. The measurable adjustability of the wall (5) produces different proportions of the travel path in the vacuum and in the gas to be measured, as a result of which the optical path length can be varied. The movement of the wall (5) produces interferences between the reflecting, unified component beams (20, 20') which can be measured by photodetectors (15, 14). <IMAGE>

Patent EP-0325849-A3 (EP)
Title: Retinoic acid receptor composition and method for identifying ligands
IPC: C12Q1/68
Filed: 1988-12-02
Abstract: A novel retinoic acid receptor is 
disclosed. The novel receptor is encoded for by 
cDNA carried on plasmid phRAR1, which has been 
deposited with the American Type Culture Collection 
for patent purposes. Chimeric receptor proteins are 
also disclosed. The chimera are constructed by 
exchanging functional domains between the 
glucocorticoid, the mineralocorticoid, the 
estrogen-related, the thyroid and the retinoic acid 
receptors. In addition, a novel method for 
identifying functional ligands for receptor proteins 
is disclosed. The method, which takes advantage of 
the modular structure of the hormone receptors and 
the idea that the functional domains may be 
interchangeable, replaces the DNA-binding domain of 
a putative novel receptor with the DNA-binding 
domain of a known receptor such as the 
glucocorticoid receptor. The resulting chimeric 
construction, when expressed in cells, produces a 
hybrid receptor whose activation of a ligand-( e.g. , 
glucocorticoid) inducible promoter is dependent on 
the presence of the new ligand. The novel method is 
illustrated in part by showing that the ligand for 
the new receptor protein is the retinoid, retinoic 
acid.

Title: Method and device to restore a staircase
IPC: E04F11/16
Filed: 1988-10-14
Abstract: The invention relates to a method and a device to restore a staircase. The restoration is effected with the aid of new tread elements (14) which are laid on top of the old steps (11, 12) and are fixed thereto with the aid of tread profiles. The cavities remaining between the old steps, the new tread elements and the profiles are filled with an assembly foam (18) which has a reaction time of several hours and during this time undergoes at most a twofold increase in volume. As a result, it is possible to foam the old steps, the profiles and optionally the tread elements in place, subsequently to assemble and align the different parts precisely, and finally to allow the assembly foam to harden. The tread profile (1) possesses three legs (2, 3, 4) arranged above one another and parallel to one another and a profiled part (6) connecting the latter, which is provided on its visible side with at least one receiving groove (9) intended to receive a cover layer (7). <IMAGE>
Patent EP-0338541-A3 (EP)
IPC: B23B1/00
Filed: 1989-04-19
Abstract: A machine tool for processing a work piece 
into a non-circular cross-sectional configuration 
according to the invention precisely processes, for 
example, a piston cylinder into a non-circular cross-­
sectional configuration by inputting simplified data.  
     That is to say, a tool thereof is moved in 
a direction (X axis) perpendicular to an axis of the 
work piece by means of two servo motors. A first X 
axis servo motor operates to position the tool roughly 
in the X direction according to the size of the work 
piece. A second X axis servo motor finely vibrates 
the tool at high speed on the basis of program data. 
Since the displacement amount of the second X axis 
servo motor is fixed by working out the program data 
of a non-circular cross-sectional contour of the work 
piece through an automatic operation device, by 
inputting elements of the work piece in a simplified 
way and then storing the program data, the invention 
makes it possible to eliminate the inputting of the 
data to some extent and to process the work piece 
precisely and at high speed.

including bis(aminoalkyl)polydiorganosiloxanes and 
alkenylaminodisiloxanes which are spontaneously converted to 
cyclic disiloxazanes. The cyclic disiloxazanes may in turn 
be converted by hydrolysis to bis(aminoalkyl)octaorgano­
tetrasiloxanes.

Title: An automatic servo gain calibration system for a disk drive
IPC: G11B21/10
Filed: 1989-09-14
Abstract: A method for automatically calibrating gain parameters of a servo control including a track position detector for a computer disk drive. The method generally comprises the step of encoding AB bursts on at least one special calibration track of a disk surface in accordance with a known off center pattern signal having a preselected frequency. Servo correction number information is also encoded on the calibration track to compensate for the off center pattern of the AB bursts. A digital signal processing technique is performed on a correction signal derived from the AB bursts and servo correction number information to detect a residual signal at the preselected frequency of the off center pattern signal. The gain of the track position detector is thereafter adjusted to minimize the magnitude of the residual signal.
