Title: Polyols, use and method of preparation
Inventor: MAGNUS GEORGE
IPC: C08G18/50
Filed: 1989-10-17
Abstract: IMPROVED POLYOLS, USE AND METHOD OF PREPARATION           Abstract of the Disclosure Alkoxylated polyols are prepared by dispersing a nitrogen-containing material, such as urea, into a dispersing media comprised of a polyether or polyester polyol and a chemical moiety capable of being alkoxylated, such as a carbohydrate, i.e. whey permeate or sucrose, lactose, etc., and reacting the resultant dispersion with a C2  - C6 epoxide to form an alkoxylated polyol having a hydroxyl number below about 600.  In certain embodiments, up to about 25% by weight of a urea material can be incorporated within the alkoxylated polyol for improved flame retardancy in the polyurethane/polyisocyanate/ polyisocyanura foams produced therefrom.

IPC: F16K17/34
Filed: 1989-10-19
Abstract: Abstract of the Disclosure A flow control (10) for controlling the rate of flow of a fluid through a flow passage over a range of varying line pressures resembles a Belleville washer and is molded from a thermoplastic elastomer having a hardness range from 40 Shore A to 50 Shore D.  The control has a circumferential outer rim (13) and a dome-shaped contour within the rim (13) which provides an apex (12), a concave downstream surface and a convex upstream surface, with the fluid flow passage (11) extending through its apex.  This flow control does not require interaction with a specifically designed seat but can simply be mounted across the flow passage which it is to control by retaining its rim portion upstream from the flow passage to be controlled.

Abstract: LABELLING MACHINE FOR THE LABELLING OF CONTAINERS     ABSTRACT OF THE DISCLOSURE      A labelling machine for cylindrical containers which are moved past a labelling station by a rotary table and which rotate past the front side of a label stack and thereby remove a front side label.  A hot adhesive is sprayed onto the container by a first adhesive unit. During the rolling of the container past the label stack, a label is adhered to the front edge of the container.  The rear edge of the label has adhesive applied by a second adhesive unit which is located near the labels which are stored in the stack.  In order to make possible a change between different container formats, the label box, the first adhesive unit and the second adhesive unit are mounted on a common sliding carriage.  The sliding carriage is translatable in the direction of the rotary table and is pretensioned in the direction of the rotary table by a spring against a stop.

Title: Production of particulate polyimide polymers
Inventor: KLOBUCAR DIRK W
IPC: C08J3/14
Filed: 1989-11-28
Abstract: PRODUCTION OF PARTICULATE POLYIMIDE POLYMERS                   Abstract of the Disclosure Described is a process for producing, in particu-late form, aromatic polyimides based on one or more 2,2-bis[4-(aminophenoxy)phenyl]hexafluoropropanes.  The process involves forming, heating and agitating in a medium composed of dipolar aprotic solvent and liquid aromatic hydrocarbon solvent, a homogeneous solution of a polyamic acid derived from a substantially equimolar mix-ture of (i) an aromatic tetracarboxylic dianhydride and (ii) a 2,2-bis[4-(aminophenoxy)phenyl]hexafluoropropane, such that a separate phase of particulate aromatic poly-imide is formed in such medium.  The process avoids difficulties caused by the tendency of the wet polyimide polymer to agglomerate into stringy or tacky masses which can foul reactor and agitator surfaces.

Abstract: TAPERED SEMICONDUCTOR WAVEGUIDES     AND METHOD OF MAKING SAME Abstract Adiabatic mode control and structural reproducibility are achieved by a tapered semiconductor waveguide structure wherein semiconductor guiding layers are interleaved with stop-etch layers and each guiding layer extends further along the propagation axis of the waveguide further than the guiding layer immediately adjacent thereabove to create a staircase-like core or guiding structure. Cladding regions of appropriate semiconductor material having a lower index of refractionthan the tapered core structure may be added to completely surround the tapered guiding structure. The profile of the tapered structure is realizable as any desired staircase-like shape such as linear, parabolic, exponential or the like. Additional layers of higher index of refraction semiconductor material may be included in the cladding region to permit additional beam shaping of the expanded spatial mode propagating along the tapered waveguide. Photolithographic masks defining successively larger exposed areas are aligned, deposited over the waveguide structure, and then removed following eachetching step. Material selective etching techniques are employed to remove exposed (unmasked) portions of guiding layers. In sequence, the exposed, formerly underlying portions of the stop-etch layers are then removed using material selective etching. Iteration of the above process steps permits a tapered waveguide structure to be defined.

Abstract: A postage meter machine having a stator part and a print rotor.   The motors, a drive, a motor switch, a battery, a logic unit, a clock module, and two position indicators are disposed in the stator part.  A catch-stop actuator, a catch-stop row sequence with three catch stops of different length as well as a date stamp with four counter  wheels  and  coordinated  stop-catch  device  are disposed in the print rotor.   The counter wheels are disposed coaxially next to each other and each exhibits twelve print positions, which are rotatable stepwise by the catch-stop row sequence.  Based on the kind of teeth and the length of the cams, either only one counter wheel or two counter wheels or all three counter wheels are rotated simultaneously by one position in case of one catch-stop row sequence step.   A coupler connects one motor to the catch-stop actuataor in a certain angular setting of the print rotor.   The  logic unit,  initiated by the clock module, controls such motor.  Depending on the date set in each case, this motor runs for such a time until the catch-stop  row  sequence  has  performed  one,  three,  twelve, thirteen, sixteen, or seventeen steps.  In each case, the respective subsequent setting of the day is achieved.
