Abstract: The invention relates to an air mattress (1) comprising a number of successive, elongate and bag-like elements, which can be filled with gas such as air or with some other flowing medium. The elements are arranged transversally with respect to the lengthwise axis (D - D) of the mattress and/or the bed, and are connected to each other successively in a band-like fashion. The successive elements (2, 2 min ) are arranged so that the lenghtwise seam joints (6; 6b) of the elementes are located at given intervals in the bottom part (1b) of the mattress, and that the areas between these seam joints are arranged to form structures which are directed upwards from the bottom part (1b) of the mattress. The invention also relates to a method for adjusting an air mattress or the like. The elements (2, 2 min ; 9, 10) of the mattress are partly filled with for instance air, so that the mattress pressure corresponds to the pressure of the surroundings when the mattress elements are not subjected to a weight load, but the mattress pressure grows in a known fashion according to the weight load of the human body or part thereof, so that the mattress elements conform to the contours of the body or part thereof, and simultaneously the surface pressure against the body or part thereof is distributed evenly over the whole body or part thereof.

Title: Mineral insulated cable manufacture
Inventor: VINNICOMBE FREDERICK J
IPC: G01N29/27
Filed: 1990-04-04
Granted: 1994-12-27
Abstract: ABSTRACT                 MINERAL INSULATED CABLE MANUFACTURE            In a method of manufacturing mineral insulated cable in which the metal tube from which the sheath is to be formed is formed from an advancing metal strip which is folded into tubular form and whose edges are continuously welded together, any defects in the weld are identified and located by continuously introducing ultrasonic vibrations into the welded region.  These vibrations either interact with a defect in the welded region to produce an echo or undergo a change in signal strength arising from transmission past a defect.  The advancing tube is continuously monitored to detect any echo or change in signal strength caused by a defect and, in response to any such identification, the advancing tube is automatically marked to indicate the location of the defect.

Title: Tamper-evident closure with improved tear strip hold-down
Inventor: PHERIGO DOUGLAS E
IPC: B65D43/16
Filed: 1991-05-24
Granted: 2001-04-03
Abstract: The hinged flap of a plastic container closure is molded while in an open position and, during molding of the flap, an elongated tear-away strip is formed along the front edge of the flap and is integrally connected to the flap by tearable webs. After the newly molded flap has first been closed, the strip is anchored releasably to the top panel of the closure and prevents the flap from opening during shipment of the container, the strip also serving as a visual indicator that the seal of the closure is intact. Anchoring of the strip is effected by pins which project upwardly from the panel and which are ultrasonically welded to the lower side of the strip. The closure is opened by lifting and pulling on the strip to break the welds at the pins and thereby enable the strip to be torn completely away from the top panel and the flap and to free the flap for swinging to an open position. The absence of the strip or the presence of a partially torn strip indicates that tampering has occurred and that the seal may not be intact.

IPC: F15B9/14
Filed: 1991-08-09
Granted: 1994-09-20
Abstract: A fluid-powered servo actuator having a body,  an annular piston, and a shaft extending co-axially therewithin. The shaft has an interior chamber located within the body with two fluid channels  extending to the chamber in which the piston is mounted.  One channel communicates with each side of the piston.  A valve spool is positioned in the shaft chamber, and a cam follower or threads are used to longitudinally move the  valve  spool  therewithin  in  response  to  its  selected rotation.   The valve spool has a pair of valve lands which, when in a neutral position, close the two channels.  When the valve  spool  is moved  longitudinally,  pressurized  fluid  is communicated with one or the other of the channels to cause the piston to move longitudinally.  Splines or rollers convert the  longitudinal  movement  of  the  piston  into  rotational movement of the shaft.  The cam follower or threads cause the resulting rotational movement of the shaft to move the valve spool back to the neutral position when the shaft has rotated by an amount and in a direction corresponding to the selected amount and direction the valve spool was rotated.
