Title: Knitting frame control - using slotted discs and photodiodes to control pattern transfer by computer thereby eliminating run back errors
IPC: D04B15/66
Filed: 1975-07-02
Abstract: A knitting frame with electromagnetically actuated needles is fitted with a disc with radial slots between lamps and photodiodes to produce distinguishable signals in synchronism with the knitting frame. An electronic computer receives these signals and determines whether each signal is the correct sequence to the preceding one. Only then does it clear the passage of knitting pattern instructions from a memory to the needle actuators. This prevents defective patterns caused by a run back of the cylinder whenever a knitting frame has stopped and is to be restarted.

Title: Liquid analyser sample-tube carrier - incorporates several holders, optical identification system and transverse and longitudinal movement mechanisms
IPC: B01L3/14
Filed: 1975-07-16
Abstract: The tube-holders are connected at their bases. Each tube has an identification clip in the form og a side-handle. Each support has a slot wide enough to accommodate the handle, so that it is visible in the space between successive supports. Each handle has several nothces. The presence or absence of a notch allows an optical detection system to give a signal representing a binary word which identifies the tube. The tube-carriers have transverse grooves in their bases which run on rails to guide the carrier when it is moved transversely, and which act as notches in which teeth can engage to move the carriers longitudinally. Used for analysing liqs., partic. biological liqs. e.g. blood or urine when a number of treatments have to be carried out. The appts. avoids the disadvantage of having to change the tubes in which the samples flow, for each different analysis, and to make different connections between the treatment units. The risk of error and of breakage and loss of appts. is considerably less than with existing appts.

Title: Plates for plate type heat exchangers - have varying types of flanged edges that clip together to form an impervious seal
IPC: F28F3/10
Filed: 1975-07-29
Abstract: A thin metal plate has a body defined by two long parallel sides and two end pars having two short sides that meet on the centre line between the longitudinal sides. Each of the six sides making up the border of the plate has flanged edges that are streamlined to allow the assembly of plates with elastic engaging and mutual covering of the flanged edges of adjacent plates. One of the two short sides of each end part has a flanged edge that forms a V-shaped gutter, and the edge of the other short side forms a V-shaped outline lying on its side, the branches of which show an obtuse angle turned towards the body of the plate. The branch connected to the body of the plate is slightly longer than the outer branch of the V-shaped flanged edge. Both long sides of the plate have flanged edges that show in cross-section a concertina shape and are at a slightly obtuse angle to the plate body so that adjacent plate sides can be spring clipped together. The concertina shapes have an odd number of shutters, the last of which is smaller than the others. A large number of bosses in relief and hollowed, having a height of half the distance between two plates, are distributed regularly over the body of the plate, so as to bear against the bosses of an adjacent plate. Also in the body of the plate are holes distributed along its longitudinal axis. The streamlined flanged edges are arranged in such a way that the plate is symmetrical in relation to a plane perpendicular to the body and passing through the transversal axis. The system reduces the leaks of prim. and sec. fluids. The streamlined flanged edges of assembled plates form aerodynamic inlets that makes the flow of fluids into the exchanger easier. Only one type of plate is required to produce a plate heat exchanger cell.
