Abstract: 2,2'-oxodisuccinate detergent builder salts (ODS), especially tetrasodium 2,2'oxodisuccinate, are difficult to dry and tend to pick up water due to the hygroscopicity of the 2,2'-oxodisuccinate; yet the present invention secures inproved granular built detergent compositions comprising ODS by an aqueous ODS/zeolite coagglomeration process, the resulting agglomerate being remarkably stable and nonhygroscopic. Other detergent ingredients, such as perborate bleach, surfactants and the like, can be dry-mixed with the agglomerates to form fully-formulated granular detergents. The invention encompasses the agglomeration process, the ODS agglomerates and granular detergent compositions containing same.

Title: Method for integrating a discrete subprogram into a main program
Inventor: MCKINNIS DAVID RAY REES
IPC: G06F9/445
Filed: 1992-12-22
Granted: 2002-07-09
Abstract: A method is disclosed for integrating a plurality of discrete subprograms with a main program. The method enables the main program to intestate any discrete subprogram stored in its directory with the main program. The method includes the step of identifying each discrete subprogram stored in the directory of the main program and creating a cross reference array to enable the main program to access the plurality of subprograms. In addition to creating the cross reference array, an event reference list of the main program is updated, enabling commands of the subprogram to be given key and menu assignments, thereby further integrating the subprogram with the main program. Similarly, the subprogram can be removed from the main program simply by deleting the subprogram from the directory of the main program.  Further features of the subject invention include a method for enabling the subprogram to request the main program to perform main program functions, and a method for limiting the number of subprograms loaded in the address space of the computer.

Abstract: Quick-disconnect couplings for three-piece rotors in a two-rotor continuous mixer for plastic materials enable a main rotor section (or "main rotor body") of each rotor to be uncoupled from a drive journal located at one end of the main rotor section and a driven journal located at the other end of the main rotor section. These quick-disconnect couplings as shown provide the following features: (a) piloted to maintain concentricity, (b) keyed to transmit torque, (c) enable quick assembly and disassembly of three-piece rotors, (d) maintain integrity of couplings bolted onto respective ends of each rotor section, (e) thus, a complete functional main rotor body is assembled with its quick-disconnect couplings (140, 141), at each end, (f) the disengageable interface between each coupling and each journal is supplied with both pilot and key, (g) concentricity and torque capabilities are built into the quick-disconnect coupling assemblies, (h) threaded locking collars captive on the journals serve to lock the disengageable interfaces together, (i) interface joints are pre-loaded by tightening the locking collars using spanner wrenches, (j) threaded locking collars do not become jammed, because torque is carried by keyed engagement at each interface, and (k) for disassembly the locking collars are backed off and main rotor bodies together with their couplings by separation at the piloted and keyed interfaces.

Abstract: A writing implement of the present invention is capable of stably feeding the ink to the tip of a writing member so that the writing member is able to draw lines in a fixed width and in a fixed ink density. The writing member is formed by superposing thin strips (13a, 13b) so as to form an ink passage (20) of the shape of a minute gap therebetween. The ink is fed to the tip of the writing member by the capillarity of the ink passage (20). Thus, the ink can be always stably fed to the tip of the writing member regardless of the change of the environment.

Abstract: The present invention is a system and method for custom tailoring and manufacturing apparel by using numerous try-on apparels (10) of differing, predetermined dimensions to make a finished product. A system (40) is used to keep track of the number of try-on apparels (10) and each of their dimensions. As a consumer tries on one of these try-on apparels (10), a device (40b, 40c) associated with the system (40) is used to collect the consumer's responses about fit. If one try-on apparel (10) does not fit, the system (40) suggests a next one to try, according to pre-defined rules. When a particular try-on apparel's fit has been approved for purchase by the consumer, this is reported to a manufacturing system (70), where a piece of apparel corresponding to the dimensions of the approved try-on apparel is cut, stitched, treated, and shipped as a finished apparel.
