Title: Blood Pressure Measurement
IPC: G06F17/00
Filed: 1982-01-26
Abstract: Blood pressure is measured by using an inflatable cuff to apply external pressure to a patient's body member, and measuring the amplitude of pressure oscillations induced in the cuff by blood flow in the body member as the cuff pressure is decreased in steps from a magnitude above an expected systolic (or diastolic) pressure to a magnitude below the expected systolic (or diastolic) blood pressure. The systolic (or diastolic) blood pressure is then determined by making a first linear approximation to a plurality of amplitude measurements occurring below the expected pressure and making a second linear approximation to a plurality of points occurring above the expected pressure, and finding the systolic (or diastolic) pressure E by setting the two approximations equal to determine their intercept D. Both the systolic and the diastolic blood pressure, and also the mean arterial pressure B (where the pressure oscillations reach a maximum) may be measured automatically using a microprocessor. <IMAGE>

Title: "Slip-shape" plastic textile bag - pillow slip construction
Inventor: SABEY ALBERT WILLIAM
IPC: A47G25/54
Filed: 1982-01-28
Abstract: A storage display and carrying bag for textile articles is made by welding together three shaped sheets of heat sealable thermo plastic material such as polythene to achieve a single outer skin and two overlapping inner skins. The overlap defines the bag access opening. The degree and position of overlap of the two inner skins is dependent upon the bulk of the article to be inserted into the bag. The bag can be folded such that one half is inserted into the gap between the inner skins with a solid carrying device eg a hanger that will thereby support both halves of the bag. The bag may be produced by feeding three webs of material from separate rollers onto a common roller in their correct relative positions and then heat-sealing and cutting the superposed sheets. <IMAGE>
