Title: Process for production of expansion-molded article in a mold of linear low density polyethylene resins
Inventor: MAEDA HIROFUMI
IPC: C08J9/232
Filed: 1988-02-18
Granted: 1991-09-10
Abstract: ABSTRACT          The present invention provides a process for production of expansion-molded articles of linear low density polyethylene resin which comprises compressing pre-expanded linear low density polyethylene resin beads having two melting points when measured by differential scanning calorimetry, the lower melting point and the higher melting point being designated TML and TMH respectively, at a temperature between the two melting points, the peak fusion area at TML being designated AL and the peak fusion area at TMH being designated AH, and satisfying: 5%  ? AH/AL ? 80% under gaseous pressure, filling a mold with said compressed beads, said mold being capable of being closed but not sealable, then venting the mold and, heating and fusing with steam in such a state that the compressive rate of the pre-expanded beads immediately before heating with steam compared to the original pre-expanded beads is maintained at 5 to 60%, thereby to produce the molded article in the shape of the mold.  These molded articles of linear low density polyethylene have a minimized dimensional shrinkage rate (good dimensional accuracy) and excellent fusion rate and surface appearance and can be produced at a high rate.

Filed: 1988-04-27
Granted: 1993-03-30
Abstract: ABSTRACT            A planing hull of a water craft comprises side keels (2) and a centre keel (4).  A downwardly open chamber (10) is defined reawardly of the centre keel (4) and is flanked on either side by the side keels (2).  The chamber (10) confines a cushion of air which supports the hull in the planing mode, air supply to the chamber (10) being wholly via the underside of the hull by being channelled between the keels (2,4) without the use of air vents which open into the chamber (10).  The absence of air vents provides improved drag at medium and low speeds.

Title: Method of detecting a deflated tyre on a vehicle
Inventor: WALKER JOHN C
IPC: B60C23/00
Filed: 1988-05-12
Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed of detecting a partially deflated tire on a four wheeled vehicle.  The angular velocity of each wheel is sensed.   The four signals are fed into a processor unit. The unit subtracts some of the signals from one pair of diagonally opposite wheels from the sum of the signals from the other pair of diagonally opposite wheels.   The processor senses when the magnitude of the result is between 0.05%and 0.60% of the mean of the two sums.   It compares the signals  for each of the four wheels in turn with the signals for each of the other wheels, senses when one of said signals is different to the average of all  four signals by more than 0.1% and in the event of both sensed signal factors being present, operates a warning device to indicate the presence of a deflated tire.

Title: Dental instrument
Inventor: EDWARDSON SVANTE R
IPC: A61C5/02
Filed: 1989-04-25
Granted: 1993-04-20
Abstract: APPLICANTS: DENTATUS INTERNATIONAL AB TITLE: DENTAL INSTRUMENT ABSTRACT A dental instrument is described by which a tooth file is automatically driven by a driver for producing alternating movement forces in the axial direction of a tool support bearing the file to a predetermined axial limit position in each direction, the distance between these limit posi-tions being such that the instrument tool support is able to take an axial position in which it is unaffected by those movement forces. The movement forces affect the tool support only when it is moved from the unaffected axial position by an external force exerted on it and then by only the one of the forces acting in the axial direction opposite to the external force. External forces in each direction are able to move the tool support up to a pre-determined maximum amplitude of action. Each movement force, besides having a first force component in the axial direction of the tool support, has also a second force component in an angular direction in order to impress also a rotational movement on the tool support when it is moved from that unaffected axial position.

Abstract: ALIGNED STRETCHED SURFACE RECORDING MEDIUM     Abstract of the Disclosure Stretched surface recording disk (SD) 10 comprises an annular support 12 having raised annular ridges 44 and 32 at or near its inside and outside diameters 22 and 30 with a base portion 24 in between the two ridges, and two annular recording medium films 14 and 16 held in radial tension and stretched across the base portion by adhering the film near the inside and outside diameters.  The major principal orientation axis of each annular recording medium film 14 and 16 is determined and the SD assembled so that the axes are aligned in the same direction.  This aligning results in SD with reduced track anisotropy due to warping of the annular support 12.  As a result, data tracks are more stable than in previous SD, track density can be greater, and the SD is generally more reliable.

The second beam is provided for temperature correction purposes, and to this end is positioned close to the first beam but free at one end, so that it is insensitive to the pressure applied to the diaphragm, while being subject to the same temperature variations  as  the  first beam. Additionally,  the second beam is positioned sufficiently close to the first beam that it can be optically excited simultaneously with the first beam via a single optical fibre.

Each transmitter/receiver element pair of the measurement frame is calibrated by controlling the amount of the light emitted from the transmitter and the threshold level of the receiver, such that the signal/noise ratio of the receiver lies above a specific limit, simultaneously with the illumination time being kept the shortest possible. By incremental measurements at least one pair consisting of transmitter element and directly opposite receiver element in the measurement frame is activated at time, and an external signal being a function of the movement of the object relative to the measurement frame is compared with the registered signals from the receiver elements for calculation of the volumes. The measurement frame is constructed in the form of horizontal and vertical transmitter- and receiver modules consisting of the transmitter elements and receiver element respectively. A computer is connected to the measurement frame for calibration of the respective transmitter- and receiver elements of the measurement frame and for calculation of the volumes being derived as a result of shadow images of the object on the receiver elements. A display is associated with the computer for display of the volume magnitude of the object. Utilization for e.g. calculation of freight charges of objects.
