Title: Bubble maker
Inventor: MESSINA GENE A
IPC: A63H33/28
Filed: 1992-04-30
Abstract: A bubble maker (10) comprises a support (12) and a pair of separate bands (14, 16) connected to the support at first and second spaced-apart positions (18, 20). The bands are adapted to extend substantially parallel and near to each other and also to be flexed and stretched so as to form a gap of substantial size between the bands. A dispenser (24) mounted on the support dispenses a bubble-forming solution near the first position, and a collector (26) mounted on the support collects excess solution near the second position. Drawstrings (52, 54) mounted on the support engage the elastic bands at positions intermediate the first and second positions for separating the bands. A pump (34) pumps solution from the collector to the dispenser. Accordingly, when the support is oriented with the first position above the second and solution is dispensed onto the bands, the bands are separated by the drowstrings, and a gentle air current is established relative to the bubble maker so that air passes between the separated bands, a portion of the solution forms a bubble and excess solution flows down to and is collected by the collector, from which it can be recirculated to the dispenser by the pump.

Title: Method and Apparatus for Validating Travelling Object-Oriented Programs with Digital Signatures
Inventor: FISCHER ADDISON M
IPC: G06F9/44
Filed: 1994-04-06
Abstract: A method of operating computers  in accordance with an enhanced object-oriented programming methodology creates a framework for efficiently performing automated business transactions. The object-oriented programming  methodology is used in conjunction with a travelling program, i.e., a digital data structure which includes a sequence of instructions and associated data which has the capability of determining  at least one next destination or recipient for receiving the travelling program and for transmitting itself, together with all relevant data determined by the program to the next recipient or destination Using the methods described herein, the data is more closely bound to the program in such a way that objects may be most efficiently transferred  from one computer  user to another without the objects being previously known to the recipient computer user. The present invention utilizes object "cells" which are data structures stored, for example, on a disk that reflects a collection of (related) objects instances  whose execution has been suspended, and which can be resumed later on the same or a different platform. The collection of object instances  can be gathered together into cells (or "electronic forms") suitable for storage or transmission to another computer user in such a way that instances are unambiguously bound to their respective class definition. The present invention also creates improved tools for creating and using cells so that electronic forms can be defined using object-oriented techniques while allowing such forms to be easily transferred among a diverse population of computer users without demanding that all users maintain compatible libraries of all object-class definition programs and without demanding that all users maintain identical synchronized versions of that class. The invention provides a digital signature  methodology to insure security and integrity, so that electronic forms (i.e., cells) composed of a collection of objects can be received and executed by a user without putting the user at risk that some of the object classes embedded in the cell might be subversive "trojan horse" programs that might steal, destroy or otherwise  compromise the security or integrity of the user's system or data.

Title: Paper machine dryer fabrics containing hollow monofilaments
Inventor: BAKER SAMUEL M
IPC: D21F5/00
Filed: 1993-02-25
Abstract: 2130756 9317180 PCTABS00025 A paper machine dryer fabric includes hollow thermoplastic monofilaments to replace at least a portion of the wefts, also known as cross-machine direction strands. Fabrics including such monofilaments may be either a woven fabric, or a spiral fabric. The deformable nature of the hollow monofilaments decreases the air permeability of the fabric, and in the case of spiral fabrics, improves monofilament retention within the helical coils between the hinge yarns. The hollow monofilaments have a solidity in the range of from about 50 % to about 80 %. A suitable thermoplastic is polyethylene terephthalate. Hollow monofilaments do not have the disadvantages of other deformable yarns, such as spun yarns, multifilament yarns or plied monofilament yarns, each of which tend to hold and entrap within their structure both water and foreign matter.

Title: Solid state thermal conversion of polycrystalline alumina to sapphire
Inventor: SCOTT CURTIS E
IPC: C04B35/115
Filed: 1994-09-15
Abstract: A solid state process for the bulk conversion of a dense polycrystalline ceramic body to a single crystal body has been accomplished by heating the polycrystalline material to a temperature above one-half of the melting temperature of the material but below the melting point of the material. As the process is a solid state process, no melting of the ceramic body is necessary to convert it to a single crystal. The process has been used to convert a dense polycrystalline alumina body (PCA) containing less than 100 wppm of magnesia to sapphire (single crystal alumina) by heating the PCA to temperatures above 1100°C but below 2050°C, the melting point of alumina.

IPC: B60J10/02
Filed: 1994-12-23
Abstract: A method and apparatus for attaching a molding to the peripheral edge of an article such as a glazing used in an automobile. A molding having a groove in its one side is extruded from an extruder. The molding is guided so that the leading end of the molding contacts the edge of an article which is held by a robot. The groove of the glazing is expanded by a guide section, and the edge of the glazing enters the groove thus expanded. The robot then rotates the blazing, while pressure is applied to the molding so that the molding adheres to the glazing. When the glazing is rotated one turn, the molding is cut. The molding may be heated from the side having the groove, and cooled from the opposite side having a lip. This facilitates the attachment of the molding without causing any deterioration of the shape of the lip.

IPC: A47G19/22
Filed: 1993-07-12
Abstract: A drinking mug, especially for small children, handicapped and hospital patients, comprising a cup (1), a lid (3) and a suction tube (5), is configured in an airtight manner so that the only access to the inside of the mug is through the suction tube (5).  Tightness is achieved by disposing the suction tube (5) on the inside of the lid (3) on a drinking spout (15), and by providing a sealing ring (29) in the joint between the lid (3) and the cup (1).  Due to the airtight construction, when liquid is sucked up an underpressure is created inside the mug which subsequently empties the suction tube of liquid. Correspondingly, an attempt by the liquid to run out through the suction tube (5) when the mug is tipped over is counteracted by the siphon effect which results from the airtight construction.
