Inventor: GETTIG WILLIAM A
IPC: A47G25/74
Filed: 1991-07-19
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE A rack for neckties includes a base member from which project a plurality of stationary elongated pins laterally spaced from one another a small specified distance calculated to allow the insertion and removal of the tail end of neckties. The closeness of the pin spacing permits the accommodation of approx-imately seventy-five neckties per foot of rack length with all of the ties being retained in a fully suspended manner, free of folds and wrinkles. The retention of the neckties is accom-plished due to one or more features evident in the construction of the tail end portion of all neckties and which provides an increased bulk in the material of the tie. The dimension of this increased bulk exceeds that of the spacing between two adjacent pins and accordingly serves to retain the neckties.

Title: Method and system for making bipolar switching to protection channel
Inventor: WACHI HIROYUKI
IPC: H04J3/00
Filed: 1991-12-19
Granted: 1996-10-08
Abstract: A method is used to switch a channel which is used for a communication between a transmitting end and a receiving end from a main channel to a protection channel . The transmitting end includes N first bipolar switches respectively having an input port for receiving a baseband signal input, a main port for outputting the baseband signal input to a corresponding one of N main channels and a protection port for outputting the baseband signal input to the protection channel. The receiving end includes N second bipolar switches respectively having a main port for receiving the baseband signal input received from the transmitting end via a corresponding one of the N main channels, a protection port for receiving the baseband signal input received from the transmitting end via the protection channel and an output port for outputting the received baseband signal input as a baseband signal output. A loss of the received baseband signal input when the protection channel is used is dependent on an arbitrary number of second bipolar switches through which the received baseband signal input passes before the baseband signal output is obtained. The method comprises the steps of (a) recognizing at the receiving end the main channel from which the channel is switched to the protection channel, (b) generating at the receiving end control information related to an amplification of the baseband signal input received via the protection channel based on the main channel recognized in the step (a), and (c) amplifying at the receiving end the baseband signal input received via the protection channel by the amplification determined by the control information generated by the step (b).

Abstract: Système de défibrillation/cardioversion implantable et méthode se servant d'une électrode composée d'une multitude de segments conducteurs distincts.  Ces derniers sont isolés les uns des autres et connectés électriquement à une unité de défibrillation/cardioversion qui produit un bloc d'impulsions électriques et coupe ce dernier en une multitude de segments d'impulsions distincts qui sont appliqués à l'électrode.  Ainsi, chaque segment conducteur reçoit une impulsion électrique précise attribuée à partir des séries d'impulsions.  De cette façon, la concentration de gaz provenant du courant ionique, produit par une impulsion de défibrillation à haute énergie, est réduite, et une plus grande quantité d'énergie est acheminée au coeur, ce qui permet de réduire l'intrant énergétique nécessaire pour l'électrode.  Cette dernière peut être plane ou en forme de cathéter.

Title: Belt conveyor training idlers
Inventor: HUTH ALAN
IPC: B65G39/16
Filed: 1991-10-22
Granted: 2003-06-17
Abstract: Apparatus is provided herein for correcting lateral misalignment of a conveyor belt. The apparatus includes an idler roller upon which the conveyor belt is adapted to run. The apparatus further includes a base frame. The apparatus further includes a tilt frame having that roller which is rotatably-mounted thereon, the tilt frame being pivotally-mounted to the base frame. The pivotal mounting between the tilt frame and the base frame can provide two degrees of freedom-of-movement between the tilt frame and the base frame.  The apparatus further includes slewing means which are operatively associated with the tilt frame and which are responsive to lateral misalignment of the conveyor belt, for causing slewing of the tilt frame and the roller generally about an axis which is substantially-normal to the plane of conveyor belt, thereby to urge the conveyor belt in a direction which is opposite to the misalignment. The slewing means includes an abutment member which is located adjacent to each edge of the conveyor belt, but which is spaced therefrom. The apparatus further includes tilting means which is responsive to the slewing of the tilt frame to cause the tilt frame and the roller to pivot relative to the base frame about an axis which is substantially-parallel to the plane of the conveyor belt further to urge the belt in a direction which is opposite to the misalignment. The tilting means includes cam members which are disposed between the base frame and the tilt frame. Such cam members are configured to cause pivoting of the tilt frame and the idler roller by a camming action with the conveyor belt engaging the abutment member. In this way, the physical urging of an edge of the conveyor belt against abutment member due to misalignment of the belt causes slewing of the tilt frame and the idler roller. This, thereby, corrects the lateral misalignment of the conveyor belt.

Title: Process-chamber flow control system
Inventor: PALMER DAVID
IPC: F24F11/04
Filed: 1992-03-13
Granted: 2002-12-24
Abstract: To control the flow of air into and/or out of a process chamber, such as a clean room, a two-stage system is disposed in conduits leading into and/or out of the process-chamber. One stage includes a regulator, having a plenum (7, 79) disposed be-tween the environment and the air source or the vacuum source. The regulator maintains in the plenum a pressure that is between the pressures of the environment and the source and that is a constant amount different from the environment's pressure. The re-gulator includes a piston (5) having a frontal face (52) exposed to air in the plenum flowing between the environment and the source; and a distal face (51) exposed to the environment's pressure. The piston is mounted so as to variably impede the flow of air through the regulator and so that the weight of the piston tends to move the piston in a direction so as to lessen the piston's impedance on the air flow. The other stage includes an adjustable valve (21, Z5, 95), located between the regulator and the envir-onment, for further impeding the flow of air.
