Abstract: A continuous paper sheet having a plurality of transversal perforation lines and a plurality of holes formed in the longitudinal margines of the paper sheet. The paper sheet is torn by means of two pairs of nipping rollers including a pair of the upper and the lower feed-in rollers and another pair of the upper and the lower pulling rollers. The pulling rollers of the latter pair rotate higher than that of the feed-in rollers of the former pair so that the part of the sheet placed between the former pair of rollers and the latter pair of rollers are pulled or given tension, being torn and separated. After the continuous paper sheet is confirmed that it is placed on a stand at the predetermined position, the width or distance of the continuous paper sheet folded is measured. The resultant of measurement is compared to the standard sizes previously inputted in a CPU in order to correct it to the approximate standard size. According to the corrected standard sire and the sheet thickness separately measured, the tearing-up operation of the pairs of the feed-in rollers and of the high speed or pulling rollers is controlled in order to give the continuous paper sheet a difference in transferring speed and to tear-up the sheet at the predetermined position of the sheet.

Title: Dynamic volume tracking in an installable file system
Inventor: WILLMAN BRYAN M
IPC: G06F15/16
Filed: 1990-08-28
Abstract: The invention is a method and system for use in facilitating  communications  between  one  or  more  data storage devices and a computer (or other elements or a computer).  The data storage devices and a number of file system drivers are provided in the computer system which includes a default file system wherein the file systems are organized  in a  linked sequence.   The computer system continuously monitors all peripheral devices in the system to detect any change in media in the peripheral storage devices or detecting the first time the computer accesses any particular data storage device.  Whenever either of the foregoing events occurs,  the first  file system driver identified in the list of file system drivers is loaded and a volume identifier is read from the media.  The location of the volume identifier is specified by the loaded filed system driver.  The volume identifier read from the media is then compared with the identifier associated with the file system driver.   If the identifiers match the file system driver is mounted, otherwise the next file system driver identified in the linked list of file system drivers is loaded.  This process is then repeated until each file system driver in the linked list has been tested or until a match is found.  A default file system is mounted if no match is found.

Title: Detrimental-substance-containing theft-deterrent device
Inventor: HOGAN DENNIS L
IPC: E05B73/00
Filed: 1990-09-06
Abstract: A device for deterring theft of a protected article, including a pin (14) and clutch (16) for attaching the device to the article, with the pin and clutch being embodied in two components (10, 12) that are adapted to be locked together on opposite sides of a portion of the protected article to prevent unauthorized removal of the device from the article. The pin has a head (40) that is anchored within one component (10); and the clutch in the other component (12) grasps the pin to provide a predetermined retaining force for resisting separation of the components by prying or pulling the components apart. The one component (10) includes three fragile elongated vials (20) that fracture when at least a predetermined pressure is applied thereto, with each vial containing a detrimental substance (22) that would damage the article if the vial were to be fractured while the device was attached to the article; and the one component (10) defines a head space (25) for enabling limited axial movement of the pinhead (40), and three guide channels (27) respectively containing three balls (29) between the pinhead and the vials. Flexible cradles (34) shield the vials from contact with the balls during a relaxed state, but yield to enable the balls to contact the vials when the balls are moved in response to the pinhead being moved in response to application to the two components of at least said predetermined threshold separation force.

Title: Device for wrapped condoms
Inventor: BACKMAN HANS
IPC: A61F6/00
Filed: 1990-01-11
Abstract: A condom (2) is packed in an envelope (1) in rolled-up state.  When it is to be used the envelope (1) is broken into two parts (3 and 4), after which the condom is rolled on with the aid of the fingers. This is sometimes troublesome. Two tapes (5 and 6) are located diametrically opposite each other and attached to the open edge (11) of the condom (2). The other ends (7 and 8) of the tapes are attached to the envelope (1) so that when the envelope (1) is opened they will be attached one in each part (3 and 4, respectively) of the envelope. When the condom is to be used, the user grips the two ends (7 and 8) with his fingers and pulls, thus effectively applying the condom (2).

Inventor: DAHL ROGER W
IPC: A61N1/375
Filed: 1990-10-16
Abstract: Implantable electrodes for defibrillation are formed of pluralities of electrode segments.  Each of the segments is relatively long and narrow.  The electrode segments can be parallel and spaced apart from one another a distance at least ten times the nominal width, with one end of each segment mounted to a transverse distal portion of an electrically conductive lead coupling the electrode to a defibrillation pulse generator.          Alternatively, segments can branch or radiate outwardly from a common junction.  In yet another arrangement, electrode segments are portions of a single conductive path at the distal end of a lead from a pulse generator, arranged in either a spiral configuration or a serpentine configuration which can align electrode segments side by side, parallel and spaced apart.  The electrode segments can be formed of composite conductors in the form of titanium ribbons or wires with a sputtered outer layer of platinum, or a silver core in a stainless steel tube, with a platinum layer formed onto the tube.  The electrodes are highly compliant yet can provide large effective areas for defibrillation, enabling a transthoracic pulsing arrangement of two electrodes on opposite sides of the heart, implanted subcutaneously outside of the thoracic region.

Abstract: RBP File No. 5827-001 ABSTRACT OF THE DISCLOSURE           A manually operable shovel in which the handle portion includes handle side parts spaced laterally apart to define a space between them in which the user's body may be located, the space being open at its end remote from the blade to allow the user to move into the space.          Each side part includes a member adapted to underlie the user's  arm from the user's hand to approximately the user's elbow.  This permits the user to stand between the side parts with arms overlying the side parts and to apply a lifting force to lift the load in front of the user.          The handle side parts then rotate with the arms of the user to provide a lever action and the user can apply a lifting force to the load in proximity to his/her body without bending his/her back.   This manner of lifting reduces back strain.
