Title: Liquid infusion apparatus - has adjustable counter regulating drip frequency set by supplying adjusting impulses
IPC: A61M5/168
Filed: 1974-11-06
Abstract: The apparatus has a chamber, to which the infusion fluid is delivered in drops, connected via a flexible tube to the patient, there being a release unit in the tube operated by a timing device to regulate the drip rate. A photoelectric cell generates a blocking signal for the release unit each time a drop arrives in the chamber. Drip frequency is regulated by an adjustable counter set to the desired value by feeding adjusting impulses to it. The counter, having a separate output for each of the adjustable frequencies, can work in conjunction with an interval generator, the outputs of both being connected to a comparator, emitting a release signal to the release unit at the appropriate interval.
Patent NL-7510584-A (NL)
Title: Vibratory drive unit - has elastic device with non-linear resistance characteristic to radial weight displacement
IPC: B06B1/16
Filed: 1975-09-08
Abstract: A supporting component is fixed to a secondary shaft so that they cannot rotate in relation to each other, and has a weight mounted on it so as to give to the complete assembly a certain amount of imbalance, due to being eccentric to the axis of rotation. Thus the weight is displaced radially outwards and increases the degree of imbalance. An elastic device normally thrusts the weight towards the axis of rotation, and this has a non-linear resistance characteristic to the radial displacement. The elastic device can incorporate a first spring (3) offering resistance to radial displacement over a first speed range, and a second one (4) coming into action at the end of this range to provide additional resistance over a further range.

Title: Determination of blood heparin concn. - by rapid, sensitive and accurate method using heparin as anticoagulant
IPC: G01N33/86
Filed: 1977-12-05
Abstract: Blood heparin concns. in heparinised patients are determined by adding serum from the blood to standardised thrombin soln. and incubating the mixt. at a selected temp. for a defined period (too short for reaction between thrombin and any fibrin degradation prod. but sufficient for reaction between thrombin and heparin). A standard portion of the mixture is then added to normal plasma that has been equilibrated at the same selected temp. The clotting time of the resulting mixture is observed; it is an inverse function of the amt. of thrombin left after reaction with heparin and is a direct function of blood heparin. The clotting time is compared with standard curves prepd. by using serum from healthy individuals to whch standard amts. of heparin had been added. Rapid, sensitive and reliable method for determining heparin in blood to give accurate monitoring when heparin is used as an anticoagulant. The relationship between heparin content and the concn. of antithrombin III can be drawn.

Title: Measuring frame for doorways - is used to measure width and height at several places in old doorways as an aid to making replacement doors
IPC: G01B5/00
Filed: 1982-01-29
Abstract: When making and fitting a new wooden door into the door-frame of an old building, the door is usually made oversize and skilled planing work is needed to make it fit, because of the difficulty of keeping a uniform gap round the edges. This measuring framework overcomes that problem. The framework is placed in the existing doorway, and L-shaped 'feelers' are extended at several points along the top, bottom and sides of the framework, until they are all just in contact with the frame. The frame can then be pulled out and the height deviations measured at either edge, and the width measured at several heights. An additional feeler in the top of the frame measures the height of the middle of the door frame. The frame-work is made in two sections, which can be folded together to make the device portable.

Patent NL-9200633-A (NL)
IPC: H04B10/135
Filed: 1992-04-03
Abstract: In known coherent optical receivers with two detectors, optical 90 DEG hydrids have a throughput </=25%. Theoretical analysis shows that a higher throughput, up to a maximum of approximately 29.3%, is possible. The invention provides such a 90 DEG  hybrid (30) of the polarisation type. In an optical hybrid (3) having a structure known per se, i.e. polarisation controllers (38, 39) at the inputs (40 and 41) of a power coupler (42), and polarisers (45, 46) at the outputs (43 and 44) thereof, the polarisation controllers and the polarisers are put into such positions, that the points on the Poincaré sphere, which correspond to those positions, comply with two conditions which guarantee a 90 DEG  phase difference and the higher throughput. For example, the positions correspond to points which represent positions in which the polarisation controllers produce mutually opposite elliptical polarisations at an angle  alpha  and the polarisers are placed linearly at angles  alpha  and - alpha , and a APPROX 32.8 DEG . <IMAGE>
