Granted: 1993-05-04
Abstract: TIRE CONSTITUTING MEMBER WINDING  TENSION CONTROLLING APPARATUS                  Abstract of the Disclosure A winding tension controlling apparatus controls tensile force to be applied to a tire constituting member spirally wound about a building drum.          The apparatus comprises a memory device for storing patterns of tensile forces, a detecting sensor for always detecting winding positions of the tire member and a processing unit for obtaining a tensile force value from a pattern of tensile force received on the basis of the memory device and a detected result from the memory device and outputting the tensile force value as a control signal.  The apparatus further comprises a regenerative control device for controlling a DC motor connected to a tension roller to cause the tension roller to rotate at a speed slower by a predetermined value than a running speed of the tire member wound about the building drum and a display device for displaying various informations concerning winding of the tire member.  In this manner, the tire member causes the tension roller to accelerate until its circumfer-ential speed becomes substantially equal to the running speed of the tire member wound about the building drum, thereby causing a tensile force in the tire member equal to the tensile force value to applied to the tire member.

Granted: 1992-04-28
Abstract: Abstract of the Disclosure Motor apparatus which converts hydraulic energy and change of state heat energy to mechanical energy.  The motor includes a main chamber divided by a piston into first and second portions.  During a first half cycle or hydraulic power stroke, a valve places the first portion of the chamber in fluid communication with a source of pressurized, saturated liquid and the second portion of the chamber in fluid communication with a drain port.  A switch senses the end of the hydraulic power stroke and causes the valve to move to  a second position wherein the first and second portions of the chamber are placed in fluid communication with one another to form a common motor chamber and drive the piston in an expansion power stroke.  Power is derived from the working fluid during the piston stroke in each direction. The motor finds particular application for energy recovery in an absorption refrigeration system.

Title: Lyophilization containers
Inventor: HAAST WILLIAM E
IPC: F25D11/00
Filed: 1989-05-25
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE The invention provides containers useful for freeze-drying of biological and other materials which can be advantageously subjected to a lyophilization process, such materials including proteinaceous materials from which moisture is removed in order to preserve the material in a dry, shelf-stable form.  The present containers allow lyophilization of the contained material with a minimum of time and energy expenditure by forming the material into a frozen shell to increase the surface area of the material and to minimize the thickness of a given quantity of material which is to be lyophilized.  In a typical embodiment of the invention, a container is provided with a congruent, flexible core which is inserted into the container to force the material into the space lying between the container and the core.  Expansion of the material on freezing acts to deform the flexible core rather than to break the container.  The material thus frozen into a shell-like conformation within the container is then subjected to a lyophilization process after removal of the flexible core.

Abstract: RCA 83,957A          CURRENT GAIN COMPENSATION AMPLIFIER                         ABSTRACT        A first pair of transistors, Q721 and Q723, operating, each, as an emitter follower, has a relatively low emitter current.  The emitter followers drive corresponding base electrodes of transistors of a second pair of transistors, Q148 and Q149, coupled as a differential amplifier.  A current gain compensating transistor Q726 has a current gain that tracks current gain variations of each of the transistors of the second pair.  A base electrode current of the compensating transistor and a second current iQ727 that is unaffected by current gain variations are summed.  The summed current is coupled via transistors Q722 and Q724 of a current mirror arrangement to first and second junction terminals, respectively coupled between the respective emitter electrodes of the emitter followers and the base electrodes of the second pair.  Currents generated by the current mirror arrangement compensate for variations in the base currents in the transistors of the second pair so as to maintain the emitter currents in the emitter followers substantially unaffected by these variations.

Abstract: ABSTRACT      For use with a modular scaffolding system, the invention herein provides a moment-arm connecting joint for providing rotational stiffness between members being joined and for attaching a first structural member having a circularly-shaped cross section to a second structural member so that shear forces applied to the first member by external loads are converted to tensile forces in the joint.  A backer plate bracket is attached to the second structural member and is adjacent to and at least partially surrounds the outer surface of the first structural member.  Fastening means fastens the circularly-shaped first structural member to the backer plate bracket so as to produce a force on the first structural member in a direction which is substantially orthogonal to a plane extending in a tangential direction with respect to the arcuately-shaped surface of the bracket.  A compressive force is, in the result, applied to the outer surface of the first member.

Abstract: It has been found that the addition of specific levels of sodium, advantageously in the form of sodium carbonate, to low sodium level binder, e.g., ammonium alginate, containing carbonaceous fuel compositions results in dramatic changes in the performance of both the fuel element themselves and, cigarettes (or other smoking articles) incorporating the fuel elements. These performance differences include variation in the yields of aerosol and/or flavorants. The addition of sodium carbonate to the fuel elements greatly improves the smolder rates and also improves puff calories, without overheating the cigarette, thereby resulting in substantial improvements in total (and puff by puff) aerosol yield. <IMAGE>
