Title: Process for separating substances from a liquid and device for carrying out the process
Inventor: STUCKART WOLFGANG
IPC: B01J19/10
Filed: 1988-05-17
Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE     A process for the flocculation, precipitation, agglomeration or coagulation of substances  or microorganisms present in a liquid in a dissolved, colloidally dissolved, suspended or emulsified state and a device for carrying out the process.          The respective liquid is exposed to one or several fields of stationary ultrasonic  waves, the ultrasonic frequency f being higher than one seventh of a cutoff frequency fo which depends on the kinematic viscosity  of the liquid and the effective radius of the particles present in the liquid.  The device is provided with an ultrasonic treatment tank which receives the liquid to be purified and is provided with an ultrasonic transducer radiating the ultrasonic waves to an opposing reflecting surface.

Title: Cooling arrangement for a dc motor

Abstract: Case 2979 IMPROVED COOLING ARRANGEMENT FOR A DC MOTOR           ABSTRACT OF THE DISCLOSURE         A commutator type, prior art dynamoelectric machine normally has an inlet for cooling air at the end of the machine remote from the commutator.  The air flows from the inlet through axially extending passages in the rotor, outwardly through spaced radial ducts in the rotor, and into the air gap.  Part of the air flows through the air gap to a collecting chamber at the commutator end of the machine to be discharged or exhausted.  Part of the air flows radially outwards through interpolar spaces in the stator, through cooling ducts in the magnet frame to a peripheral passage which is connected to the collecting chamber at the commutator end.  This invention provides a second collecting chamber at the drive end of the machine opposite the commutator end, communicating with the air gap and also with the peripheral passage at the drive end.  Thus the air flow is divided after passing through the rotor and flows to the nearer collecting chamber providing a shorter flow path.

Abstract: Abstract During the wrapping of articles in blanks, the latter are severed from a web of material and fed to a folding turret.  When the delivery of articles to be wrapped is inter-rupted, the severing of blanks and the feeding of these to the folding turret are also interrupted.  For this purpose, whilst knife rollers continue to run, the web of material is stopped after it has been conveyed beyond the severing point an amount corresponding to a follow-up portion.  The severing knives of the knife rollers rotating further are moved out of their cutting position.

Abstract: New nucleophilic urethanes are described and claimed, which are the reaction product of a monoisocyanate, a diisocyanate or a polyisocyanate with a basic alkoxylated amine whose  hydroxyl  functionality has  been adjusted to a value of 0.5 to 2 by etherification, esterification and/or reaction with a monoisocyanate. These compounds are particularly used, individually or as a mixture, as neutralizing nucleophilic compositions in desensitizing inks for the printing by dry or humid offset,  typographic, or flexoqraphic methods, destined to locally neutralize the electrophilic layer of a chemical pressure sensitive copying set.  The disclosed compounds have a better neutralizing power which allows to reduce the weight per surface unit of the desensitizing printing by at least a third.

Abstract: ABSTRACT OF THE DISCLOSURE          A tiltable tripod stand includes a main post to be selectively tilted and three tripod legs having upper ends which are pivotally connected at the main post.  One end of an articular arm is pivotally con-nected to each leg intermediate its ends and the other end of the arm is pivotally connected to the main post. Two related embodiments for tilting the stand are dis-closed.  In one, there are two upper holding members on the main post, one movable with respect to the other. One tripod leg is pivotally connected to one upper holding member and another leg is pivotally connected to the other upper holding member so that movement of the one with respect to the other changes the tilt an-gle of the leg and tilts the main post.  In the other embodiment, there are two relatively movable lower holding members.  The articular arm from one tripod leg is connected to one lower holding member while the ar-ticular arm from another leg is connected to the other lower holding member such that movement of the one low-er holding member with respect to the other pivots the respective articular arms which changes the tilt angle of the respective legs which tilts the main post.  In one embodiment, the legs are equally spaced around the main post.  In another embodiment, the angle between the legs which the main post tilts away from is in-creased to improve stability.

Title: Process for fabricating integrated circuits having shallow junctions
Inventor: LIFSHITZ NADIA
IPC: H01L21/768
Filed: 1989-05-24
Granted: 1993-03-16
Abstract: Abstract For integrated circuit devices with strict design rules, junctions defining the source and drain are typically more shallow than 0.25 µm and aremade through vias having an aspect ratio greater than 1.1. Suitable electrical contact to such a shallow junction is quite difficult. To ensure an appropriate contact, an adhesion barrier layer such as titanium nitride or an alloy of titanium and tungsten is first deposited. Tungsten is then deposited under conditions which produce a self-limiting effect in a prototypical deposition on silicon. Additionally, these tungsten deposition conditions are adjusted to higher rather than lower deposition temperatures. Subsequent deposition of aluminum if desired, completesthe contact.

Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE           Multi layer  footwear  formed  of  laminated  layers  of material which are sealed together with a polymeric glue used in the original manufacture of the footwear to secure the various layers of material together.  The layers of material held together by polymeric glue are capable of being heated to a degree at which the footwear, when placed in a vacuum bag or compression chamber, is molded to adopt the shape of the foot inside the footwear under atmospheric pressure once pressure inside the bag is reduced or pressure in the compression chamber is increased.  The footwear is heated to the point where the synthetic components of the layers of material are flexible under thermoforming conditions, but within a temperature range in which the polymeric glue continues to perform as an adhesive so that the sealed laminated surfaces do not separate.   A polymeric glue is used because it can secure the laminated layers of material together during manufacture of the footwear and continue to perform as an adhesive during heating and cooling of the laminated layers of material in a custom-molded condition.

Abstract: ABSTRACT OF THE DISCLOSURE A propulsion air stream deflecting apparatus for an air cushion vehicle including a hull and an air duct, mounted  on  the  hull,  with  a  propeller  fan.    The propulsion air  stream deflecting  apparatus  includes  a plurality of rudders, each mounted on the hull adjacent to the rear open end of the duct for pivotal movement about a vertical axis, the rudders being adapted to close the rear open end of the air duct.   A rudder control mechanism is operatively connected to the rudders for controlling  the  pivotal  movement  of  the  rudders  to selectively provide a propulsion thrust and a steering thrust to the hull and to provide a closed position in which the rear open end of the air duct is closed by the rudders.   A flap is pivotably mounted at the rear end thereof to the duct such that the flap closes an opening, formed at the rear end of the air duct,  at a closed position thereof where the inner  face of the flap is substantially flush with the inner surface of the air duct.   The flap turns outwardly to open the opening due to an increase in pressure in the duct in the closed position of the rudders, for deflecting the air stream, passing out the opening,  forwards to provide a forward thrust to the hull for braking, stopping or rearwardly moving the hull.  A flap urging spring urges the flap to close the opening.
