Title: Caliper sensor of the contacting type
Inventor: NORTON MICHAEL K
IPC: G01B5/06
Filed: 1990-04-18
Abstract: ABSTRACT OF THE DISCLOSURE         A caliper sensor of the contacting-type for measuring the thickness of travelling sheets of thin materials having coated surfaces.  The caliper sensor has first and second skid members that ride on opposite surfaces of a travelling sheet.

Title: Fatty composition
Inventor: DECIO MAURIZIO
IPC: A23L33/26
Filed: 1990-05-14
Abstract: L 7180 (R) ABSTRACT            The present invention is concerned with a fatty composition containing more than 50 wt.% fat, comprising, calculated by weight of fat: (a) 0.5 to 40 % unrefined olive oil; (b) 5 to 80 % polyol fatty acid polyesters; and optionally (c) less than 94.5 % refined triglyceride oil.            The fatty compositions according to the invention were found to have a mouthfeel that is very much alike that of olive oil. Futhermore, surprisingly, the long aftertaste, which is characteristic of olive oil based salad oils, is also observed for the combination of polyol fatty acid polyesters and unrefined olive oil.            Another aspect of the present invention is the use of polyol fatty acid polyesters as a replacement for refined olive oil in olive oil based fatty compositions which contain from 0.5 to 40% of unrefined olive oil.            Yet another aspect of the present invention is the use of a fatty composition according to the invention described hereinbefore as a salad oil.

Abstract: A water sensing type power breaker circuit is incorporated into an electric appliance such as a hair dryer or the like and is used to cut off a power supply to prevent an accident due to an electric shock immediately when the electric appliance is dropped into the water.         A water sensing type power breaker circuit includes first and second contacts having one polarity connected to a power supply and the other polarity connected to a load, an impedance element circuit including first and second impedance elements connected in series each other and which is connected in parallel with the load, a water sensing element made of an electrical conductor connected to an intermediate point between both the impedance elements through a conductor, and a relay for detecting a current flowing through the conductor to open the first and second contacts when the current flows through the conductor. The relay is held by itself so that the first and second contacts are opened. The water sensing type power breaker circuit is inexpensive and has a small occupancy volume so that it can be directly incorporated into the electric appliance such as a dryer.

Title: Method and apparatus for concealing the enablement of a device by modifying a status word
Inventor: JERRIM JOHN W
IPC: G06F13/00
Filed: 1990-09-17
Abstract: A status word modification device. A serial communications device (11) contains two universal asynchronous receiver transmitters (UARTs) (14, 15). Each DART contains a first in, first out (FIFO) buffer (14a), two status buffers (14b, 14c), and a FIFO control register (14d). If the applications program in the host (10) is an enhanced application program which supports the use of the FIFO buffer (14a), then the program will cause FIFO enablement instructions to be written into the control register (14d). In this case, the interface circuit (22) allows the status words to pass unaltered whenever the host (10) reads the status buffers (14b, 14c). However, if the applications program is a standard applications program which does not support the use of the FIFO buffer (14a), then the program will not write to the control register (14d). In this case, the interface circuit (22) will alter the value of selected bits of the status words if the user has enabled the FIFO buffer (14a) and the host reads the status buffers (14b, 14c). The alteration of the status word prevents the standard applications program from treating the FIFO-related bits in the status words as data errors.

IPC: B60J10/79
Filed: 1990-09-17
Abstract: A weather strip is provided having a base portion which is to be attached about a door opening, a tubular sealing portion composed of a seal wall which is pushed up by a peripheral edge of a door glass and side walls for connecting inner and outer ends of the seal wall to the base portion.  An elongated coextensive insert composed of a solid material, such as solid rubber or synthetic resin, is embedded in the corner defined by the connection of the seal wall to the outer side wall.  When the seal wall is compressed by the peripheral edge of the door glass, deformation of the outer side wall provides excellent sealing properties.  Furthermore, the insert of the invention limits outward movement of the door glass in response to pressures encountered when the motor vehicle is driven at high speed.

Abstract: A method for variably making tie bar guides us-able to guide tie bars within locking system housings hav-ing different inner dimensions, which tie bar guides have a body portion including four sides substantially aligned with an opening through the body portion for slidably re-ceiving a tie bar. A mold block defines an opening for the body portion of the guide and receives material in a sub-stantially flowable state.  A cylindrical channel is also provided in the mold block along one side of said body portion opening.  A semi-cylindrical pin is secured within the channel, which pin is pivoted to open a selected por-tion of the channel to the mold block opening and thereby extend the mold block opening and contiguous open channel to a selected outer dimension.  Further, at least one slot is provided along a second side of the body portion open-ing.   Prior to flowing material into the mold block,  a selected number of substantially uniform slats sufficient to block the slot at the selected outer dimension are in-serted into the slot.  Finally, material is flowed into the mold block opening for forming the selected tie bar guide, the material is allowed to harden into the shape of the selected tie bar guide, and the tie bar guide is removed from the mold block.

Title: Urokinase-type plasminogen activator receptor
Inventor: DANO KELD
IPC: C12Q1/68
Filed: 1990-04-09
Abstract: Pure human cellular receptor for urokinase plasminogen activator (u-PAR) and forms thereof, including a truncated water-soluble form produced by cleaving or removing a glycosyl-phosphatidylinositol anchor, are provided, as is cDNA for u-PAR.  Cell surface plasminogen activation, believed to play an important role in tissue remodelling, particularly during cancer invasion, is inhibited by antibodies against u-PAR and by inactivated analogues of u-PA.  In situ hybdridization showed presence of u-PAR mRNA in the invasion front of colon carcinomas, proving the diagnostic utility of the cDNA. Water-soluble u-PAR is useful for inhibition of u-PA  catalyzed plasminogen activation in solution.
