Title: Apparatus for producing plate flanges by bending
IPC: B21D5/04
Filed: 1989-07-29
Abstract: The main starting point was that the workpiece (13) can be clamped between two holding punches (11, 12) designed as counter tools, a link (18) carries, at its two jaw edges, in each case one of two bending tools (24, 26), and a drive device (20) for essentially vertical tool movements is provided outside a drive device (19) for essentially horizontal tool movements. The intention is, with a small outlay, on the one hand to permit rapid switching to the other bending tool, and, on the other hand, to offer ample space for bending workpiece parts projecting a long way. The link (18) is therefore divided, in a manner of a hinge, into two cheeks (16, 17) which can pivot separately about the link axle (23) and each carry one of the two bending tools (24, 26), and a drive device (20, 21) is articulated on each of the two cheeks (16, 17) for essentially vertical tool movements. The drive device (20) assigned to the upper bending tool (24) is preferably designed for the larger maximum travel. The bending device can be employed universally in an enlarged field of use since wider plate flanges and, ultimately, more complicated edge profiles can be produced. <IMAGE>
Patent EP-0355747-A3 (EP)
IPC: C30B15/28
Filed: 1989-08-18
Abstract: The present invention relates to a method and 
apparatus for mono-crystalline growth of a dissociative 
compound semiconductor. The method, which is based on the 
Czochralski method, includes the following steps. First, a 
first volatile component material and second material of 
the dissociative compound semiconductor are prepared. The 
first material is placed on the bottom of an inner air-­
tight vessel which is contained in an outer air-tight 
vessel. The second material is contained in a crucible 
supported in the inner vessel by a lower shaft extending 
from the inside to the outside of the inner vessel. The 
first material is, next, heated for evaporating so as to 
react with the second material. Therefore, the 
dissociative compound semiconductor is synthesized in the 
crucible. Then, temperature of a furnace installed on the 
inner vessel is adjusted so that the pressure of the gas of 
the first volatile component material in the inner vessel 
is controlled. A single crystal is pulled up from the melt 
by an upper shaft extending from inside to outside of the 
inner vessel, thereby the single crystal is grown. The 
improvement is that the pulling-up step includes the steps 
of: measuring the weight of the growing crystal, the 
weight influenced by a difference between the interior 
pressure of the inner vessel and a pressure outside of the 
inner vessel; correcting the measured weight of the 
crystal for the error due to the pressure difference, 
thereby obtaining an accurate estimate of the weight of the 
crystal; and controlling a diameter of the growing crystal 
 
 
on the basis of the weight estimate of the crystal.

Patent EP-0370501-A3 (EP)
IPC: C09D133/14
Filed: 1989-11-23
Abstract: Acrylic coating resins with attached light 
stabilizer functional groups are provided, which resins 
are prepared by reacting light stabilizer hydrazides, 
LS-C(=O)-NR³-NH₂, with an acrylic prepolymer containing 
at least two different types of reactive functional groups, 
one of which is a hydroxyalkyl ester group and the other 
is carboxyl, anhydride, epoxy or isocyanate. LS is a light 
stabilizer moiety, e.g., of formula 
   
     wherein R³ is, e.g., hydrogen and R¹⁵ is, e.g., a direct 
bond. The reaction may be carried out in an inert solvent 
or in the bulk state.  
     The acrylic resins so produced are particularly 
useful in the stabilization of enamel or lacquer coatings 
and exhibit outstanding weatherability and durability. 
As a result of being chemically bound, the light stabilizers 
are resistant to loss due to volatility and extractability 
during typical coatings bake operations and exposure to 
the elements of weather.

Title: Polymeric thickeners
IPC: C09J7/32
Filed: 1989-08-24
Abstract: A fluid composition that is a solution of an 
associative polymeric thickener in a solvent system 
comprising water miscible polar organic solvent can be 
thickened by diluting the composition with water. It 
can also be thickened by volatilising the solvent. A 
prepasted wallcovering can be formed by spreading a 
coating of the fluid composition, at a low viscosity, on 
the back of the wallcovering and then volatilising the 
solvent to form a coating that, when rewetted by water, 
provides a high viscosity and adhesive coating. 
Downhole aqueous fluids, such as fracturing fluids, can 
be viscosified by pumping the fluid composition downhole 
where it mixes with additional water and thus thickens 
it.

Title: Refrigerator incorporating thermoelectric modules with reverse thermoelectric effect
IPC: F25D11/00
Filed: 1989-05-10
Abstract: The cold side of the 
module(s) (1) is coupled to a dissipator element (2) facing 
directly onto the refrigerator compartment (9). The hot side 
faces onto a ventilated dissipator element (3) that dispels 
the calories generated by the reverse thermoelectric 
process. Appropriate thermic insulation (12) between the hot 
side and the cold side optimizes the use of the 
refrigeration units produced. The thermoelectric module (1) 
is powered by direct low-voltage current flowing in one 
direction only and such as to generate on the cold side 
the amount of refrigeration units necessary to suitably 
cool a refrigeration compartment which is capable of 
performing its traditional function without limits. The 
refrigerator according to the invention can be 
subordinated, by means of an electronic circuit (6), to the 
signal transmitted by a temperature sensor located inside 
the refrigerator compartment which enables the user to 
set up a temperature-control program, and to select 
precisely defined operating conditions.

Filed: 1990-07-10
Abstract: An injection molding system having at least one insulation gate seal (12) extending outwardly to bridge an insulative air space (34) between a heated nozzle (10) and the adjacent cooled cavity plate (22). Each seal (12) has a central bore (36) therethrough to convey pressurized melt from the nozzle to the aligned gate (42).

reproducing information on and from an optical recording 
medium. The optical head system comprises a light source (1) 
for emitting a light beam, a collimator lens (3) for causing the 
light beam from the light source means to become a parallel

photodetector assembly comprises first and second 
light-receiving portions (A, B) which are placed on a common 
substrate. One of the two separated light beam is incident 
on the first light-receiving portion so as to obtain an 
focus error signal and the other separated light beam is 
incident on the second light-receiving portion so as to 
obtain a tracking error signal.

Filed: 1990-02-13
Abstract: A fuel pumping apparatus of the rotary distributor type 
includes a main pumping plunger 12 and an auxiliary 
plunger 20 operable at the same time by a cam. During 
inward movement fuel is displaced by the pumping plunger 
to an outlet 15. The auxiliary plunger 20 displaces fuel

the initial inward movement a first flow path 45, 46 to 
drain from the bore 11 containing the pumping plunger is 
open but this is closed upon further movement of the 
shuttle until a second flow path 45, 41, 43 is opened. 
The second flow path includes a groove 41 having an 
inclined edge 42 so that the angular setting of the 
shuttle determines the amount of fuel supplied through 
the outlet. A valve 38 is also provided to allow fuel

Filed: 1990-03-06
Abstract: An output apparatus comprises: a cache 
memory (4) to temporarily store the bit map pattern 
data which was developed to the bit map pattern 
on the basis of character information; an 
accumulating device to accumulate a plurality 
of bit map pattern data extracted from the cache 
memory (4); a rewriting unit to rewrite the bit map 
pattern data stored in the cache memory (4); a print 
controller (8) to print on the basis of the data 
accumulated in the accumulating device; a 
detector to detect an operating state in the 
print controller (8); and a control unit (5) to control 
the data rewriting process in the cache memory (4) 
and the data clearing process in the accumulating 
device in accordance with the operating state 
detected by the detector. Since the rewriting

operation, even if a paper jam occurred, there 
is no need to develop to the cache memory (4).
