IPC: B29B11/06
Filed: 1988-06-08
Abstract: The present invention is a manufacturing method of a rigid or 
semi-rigid foamed material which comprises a foaming process to 
make a practically thermoplastic foamed material wherein isocyanate 
component is reacted with polyol component in the presence of 
organic foaming agent and/or water in a condition that a quantity 
of the isocyanate component is present in excess of the stoichio­
metric equivalent quantity to the polyol component and water in the 
reaction and a successive cure molding process wherein the said 
practically thermoplastic foamed material is contacted with water 
or steam to react the isocyanate component remaining therein with 
water while heating.  
     The foamed material obtained by the first foaming process is 
not reached to the final curing of the remaining isocyanate and 
rigid or semi-rigid at room temperature, but it is softened by 
heating enable to be used for deep draw molding in the successive 
cure molding process without crack, split, or demolition. Then, it 
is contacted with water or steam in the final cure molding process, 
to react the isocyanate component remaining therein with water to 
proceed to final curing, thus becomes a rigid or semi-rigid foamed 
material without softening by heating.  
     The intermediate practically thermoplastic foamed material can 
be laminated with facing materials or reinforced with glass fiber 
non-woven cloth etc. to give a composite panel with excellent 
properties such as light weight, stiffness, heat insulation, 
acoustic insulation and moisture resistance suitable for a molded 
ceiling or a door panel etc. for automobile use and a partition or 
 
 
a screen for interior use.

Title: Electromagnetic switch gear
IPC: H01H50/30
Filed: 1989-08-23
Abstract: The invention relates to an electromagnetic switchgear, in particular circuit-breaker. 
<??>With electromagnetic switchgear, in particular contact breakers, there is a significant requirement for constructing the circuit-breakers to be bounce-free. Due to the striking of the contact bridge support at the end of the switch-off process on the housing, particularly when plastics such as thermoplasts are used for the contact bridge support, rebouncing phenomena have been almost unavoidable. The present invention is intended to reduce these rebouncing phenomena substantially. 
<??>This is done by providing projections on the housing which are of unequal height in the movement direction of the armature, and which can project through openings of the contact bridge support so that the projections can come into contact with a metal part, preferably the armature itself, during switching off. 
<??>Electromagnetic switchgear with alternating current and also direct current magnet system.

IPC: B23B27/14
Filed: 1989-12-18
Abstract: An indexable cutting insert (15) of the type having a corner (25-27) 
radius and a corner angle adapted for finishing operations 
comprises a pair of substantially parallel spaced apart faces 
and at least one peripheral side surface being substantially 
normal to said faces. A pair of straight cutting edges (41-43) extend 
away from the corner at the juncture of the peripheral side 
surface and a plane positioned closely adjacent and below the 
juncture of a respective face. To break the chips formed 
during cutting, a chip breaker recess (33) extents rearwardly and 
along the cutting edges. The chip breaker recess includes a 
descending control surface (34) leading to the bottom of the recess 
followed by an ascending control surface (36). The descending 
control surface comprises a first (51) and second (53) planar descending 
control surface with the first surface being at a shallow angle 
and the second surface being at a steep angle. The ascending 
surface directs the chip upwardly toward a central island (17) 
formed within the plane of a respective face and away from the 
insert and the cutting edge. The chip breaker recess (33) 
incorporates an additional shallow chip control recess (59) formed 
by a raised land extending outwardly toward a corner (25-27) from the 
central island along a bisector of a respective corner and a 
raised bottom surface extending above the bottom of the main 
chip breaker recess and around the corner. The additional chip 
control surfaces forming the shallow recess include an 
ascending corner chip control surface (61) extending upwardly from 
the raised corner bottom control surface (57) at a relatively steep 
angle. The recess is configured to change the curling motion 
of the chip at various depths of cut to enhance the chip 
breaking forces.

Title: Print data generator
IPC: G06F3/12
Filed: 1989-12-27
Abstract: A print data generator uses bit-mapped font data to 
modify bit-mapped image data by shifting a series of font words 
followed by an all-zero word through a bit offset S and performing an 
operation on those bits of image words and shifted font words that 
correspond to enable bits in converted mask control words. To create 
the converted mask control words, the print data generator has a mask 
control data source for generating source mask control words 
consisting of S disable bits followed exclusively by enable bits, and 
a mask control data converter that passes the first source mask 
control word through unaltered, substitutes all enable bits for the 
next (N - 2) source mask control words, and inverts the Nth source 
mask control word. By generating and converting mask control words 
automatically, the print data generator creates print data rapidly 
without overloading its controller.

Title: Uv curable gels
IPC: C08L83/08
Filed: 1989-09-27
Abstract: Compositions which cure to gels by exposure to 
ultraviolet radiation are made by blending a photoinitiator 
with an acrylamide functional polyorganosiloxane having 1 to 
2 siloxane units which contain acylamide groups which can be 
acrylamide or a combination of acrylamide and acetylamide. 
The hardness of the gel can be adjusted by varying the ratio 
of acrylamide and acetylamide in the polyorganosiloxane where 
the harder gels have the highest percentage of acrylamide 
groups. The autoclave stability of the gels can be increased 
by including in the compositions a tertiary amine which 
neutralizes the by-produced acids from decomposition of the 
photoinitiators. These gels have low temperature 
flexibility, can be made with a durometer to fit the 
particular application and can be made to have autoclave 
stability. The gels are useful as encapsulants for 
electronic devices.
