Title: Borated overbased material
Inventor: FISCHER JOSEPH P
IPC: C10M159/00
Filed: 1987-12-18
Granted: 1993-06-15
Abstract: ABSTRACT   A high carbonate content borated product is obtained by mixing an overbased sulfonate and any required inert liquid medium, borating the mixture at a temperature less than that at which substantial foaming occurs, raising the temperature of the borated mixture to a temperature in excess of the boiling point of water within the mixture and separating the water  from the  reaction mixture while retaining the carbonate in the mixture.  The product is a very fine size organic source of boron which may be easily dispersed in a lubricating oil or grease for its anti-oxidant, anti-rust and frictional characteristics and for its extreme pressure qualities.
Patent CA-1291773-C (CA)
Title: Sheet insertion apparatus
Inventor: PETERSEN GODBER
IPC: B65H5/30
Filed: 1987-12-23
Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE.       To insert a plurality of insert sheets (2') simultaneously into multi-sheet products (2), for example folded inserts into already folded newspapers, a first carrier structure (3, 3') retains the multi-sheet products in essentially open  V-shaped position.    A second carrier structure, located above the first carrier structure, retains the insert sheets.  In accordance with the invention, for insertion,  an auxiliary holder (19-26) grips insert sheets from the second carrier structure and, upon spreading apart of the first carrier structure, and downward movement of the auxiliary holder, transfers the inserts  into the multi-sheet products.  If the first carrier structure does not retain any multi-sheet products, the arrangement can also be used for transfer from one carrier structure to another and also to remove defective sheets from the second carrier structure by gripping them and depositing  them on  a  defective-sheet transport belt (54).

Title: Stabilized moisture curable polyurethane coatings
Inventor: SCHOENER THOMAS E
IPC: C08G18/08
Filed: 1987-12-23
Granted: 1993-11-30
Abstract: STABILIZED MOISTURE CURABLE POLYURETHANE COATINGS                 ABSTRACT OF THE DISCLOSURE Disclosed is a method for improving the pot life of moisture curable polyurethane coating compositions. Such enhancement is accomplished by blending with said coating composition a stabilizing amount of a stabilizing agent from the group of a mercapto compound, a polyphenol characterized by being reactable with an isocyanate group in the presence of a tertiary amine catalyst, and mixtures thereof. Stabilizing amounts of the stabilizing agent typically range from about 1% to 10% by weight. The enhanced pot life is realized even in the presence of significant quantities of water.

Title: Connection arrangement
Inventor: EKMAN KJELL R
IPC: F16L37/44
Filed: 1988-01-04
Granted: 1991-05-21
Abstract: A B S T R A C T            Included in a connection arrangement is a valve device (4) which is  so  arranged  as  to be  capable of  longitudinal  displacement inside a supporting device  (3).  During its opening movement the valve device  is  capable  of displacement  into  a space arranged inside the supporting device, which space is sealed in relation to a fluid capable of connection to the arrangement with the help of the valve device and a sealing device (5a, 5b). An enclosed volume is thus formed with the help of the supporting, valve and sealing devices.  Compressible  air  or  gas  enclosed  within this  volume assumes  a  first  pressure with  the valve device  in its  closed position,   which   first  pressure  preferably   corresponds   to atmospheric pressure, and assumes a second pressure which exceeds the  first  pressure  with  the  valve  device  in  its  fully  open position, which second pressure is less than the maximum pressure of  the  fluid.  Alternatively,  the  volume  which  is  sealed  in relation to the aforementioned fluid may be in communication with the outside.

Inventor: KIESEWETTER LOTHAR E
IPC: H01L41/12
Filed: 1988-01-20
Granted: 1992-10-13
Abstract: ABSTRACT      Method and device for making a first body (8), having magnetostrictive properties, and a second body (6), against which  said first body is in bear-ing contact with a certain grip between the contact surfaces, to move with respect to each other while substantially maintaining said grip. According to the invention a magnetic field is made to sequen-tially influence only one of adjacent partial sec-tions of said magnetostrictive body (8), starting from the front end of the body as seen in the in-tended direction of movement. The magnetic field is adjusted so that the respective partial section under the influence of the magnetic field undergoes an increase in lengh, at the same time being subject to a contraction in the transverse direction which is big enough in order to decrease, preferably eliminate the grip between the bodies. The device includes a rod (8) of magnetostrictive material, which is clamped within a tubular body (6), one end of which being attached to a rigid supporting struc-ture. The magnetostrictive rod (8) is connected to a bar, a link etc. having its opposite end connected to the element to be actuated by the movement of the rod in the tubular body (6).            Fig 2

Inventor: SIBALIS DAN
IPC: A61N1/32

Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE An electrophoretic/electro-osmotic transdermal drug delivery system for passing at least one drug, or therapeutic compound, through the skin membrane of a patient by way of a drug reservoir or gel for delivery to the systemic blood of a patient in selected, periodic pulsations.  The system can be varied to accommodate various types of therapeutic compounds having varied characteristics and purposes.   The system includes a current oscillator that applies periodic electrical variations to the system in order to trigger rhythmical variations of the potential and resistance of the skin membrane so as to cause oscillatory electro-osmotic streaming of the liquid with the therapeutic compound across the skin membrane in synchronization with the oscillator to the systemic blood of the patient in response to the rhythmical variations.  The oscillator causes the power source to deliver a periodic pulsating current that alternates with periods of no current in the system or that alternates with periods of a different current.  The pulsating current is of greater value than the different current.  The pulsating current is applied for relatively short periods relative the periods of non-current or the periods of different current.  The different current can be either positive or negative current.  During periods of negative current the liquid with the therapeutic compound can tend to be drawn from the skin membrane into the drug reservoir or gel.

Abstract: A window lock having plural ramped keepers for  a  window  sash  and  plural  rollers  movably associated with a slider mountable on a window frame to provide multi-point locking.  The ramped keepers are constructed and related to enable delayed lock-up of one roller and ramped keeper relative to the other in  order  to  assure  locking  of  racked  or  warped windows.  A roller and associated ramped keeper are bevelled to counteract any flexibility that might be encountered in a flexible window, such as a window made of vinyl.  The actuating mechanism provides for toggle positioning of the rotatable actuating handle and associated drive link to prevent movement of the lock mechanism  by  outside  forces  other  than  the handle.  One or more tie bars, each having a roller, can be  associated with the slider to provide  for variation in the number of locking points and with further variations being achieved by the length of the tie bars as well as the number of rollers mounted thereon.
