Abstract: 1303659 Cathode materials and processing GENERAL ELECTRIC CO Ltd 12 Nov 1970 [12 Nov 1969] 55452/69 Heading H1D In a reverse biased PN junction cathode the junction intersects a surface of the cathode in a closed loop, electrons being emitted only from the vicinity of the loop when the reverse bias is applied. A flat square block of P-type SiC is recessed by ultrasonic machining or chemical etching and a circular region 3 of N-type SiC grown epitaxially. The surface is lapped to expose a circular PN junction. The region 3 may be formed by diffusing N 2  through a mask, by ion implantation or by alloying a dopant into the crystal. In other embodiments the cathode comprises layers 24, 25, 26 of P-type, intrinsic and N-type SiC with a region 27 of P-type SiC extending to the surface 27. Alternatively the P-type layer may be replaced by a support and region 28 by a ring of P-type SiC extending through the N-type layer into the intrinsic layer to provide two loops. Applying potential alternately to contacts on the N-type layer inside and outside the ring produces emission alternately from each loop. The cathodes are used in C.R.T.'s and may be cleaned and emission increased as described in Specification 1,134,681.

Abstract: 1310875 Checking the positions of slots in cylinders BENTLEY MACHINE DEVELOPMENT CO Ltd 31 March 1970 [29 March 1969] 16594/  69 Heading G1M A probe for checking the positions of slots in cylinders comprises a support 1 for mounting on a gauge, a member 4 mounted on the support so that at least a part moves substantially longitudinally, a feeler 24 with a tip extending transversely with respect to the feeler, resiliently mounted on the longitudinally movable part of the member for movement of the tip transverse to the said longitudinal movement, there being abutments on either side of the member to limit its movement 9a, 17 and a further abutment 25 on the member to limit movement of the tip. A probe gauge more suitable for checking the positions of coarse slots about a cylinder is adapted to test the position of fine slots or tricks in the cylinder of a knitting machine. A feeler 24 mounted on feeler arm 18 is pivoted at 20, 19 to a bifurcated lever 4, itself pivoted at 1a 1b to a mounting bracket 1 on a cylinder 2 surrounding a gauge 3. Springs 21, 7 respectively bias the feeler and lever towards the cylinder to be measured. Ball end 3a of the probe of gauge 3 bears on a face 18b of feeler arm 18. In operation, gauge 3 is brought towards the cylinder 26 until feeler tip 24a engages in a slot 26a. Stop 17 and adjusting rod 12 are set equal amounts clear of lever 4, stop screw 25 is set clear of arm 18, and the deflection of the ball end 3a of the probe arm of gauge 3 is recorded. The gauge is then withdrawn and returned in the directions of arrow V, the cylinder 26 being turned by an amount equal to one "pitch". As the gauge moves forward, the bias of the springs having turned feeler 24 clockwise as shown in Fig.1, the tip of feeler 24 engages the cylinder beside the next slot and forward movement of gauge 3 causes the feeler to slide along until it drops into the indexed slot. The deflection of the probe ball 3a is again recorded and deviation from the first position indicates the pitch error.

Title: Multieffect distillation plant
IPC: B01D3/06
Filed: 1970-11-23
Abstract: 1314697 Multieffect distillation plant UNITED KINGDOM ATOMIC ENERGY AUTHORITY 23 Nov 1971 [23 Nov 1970] 55697/ 70 Heading B1B Liquid is distilled in a plant comprising an outer shell divided by vertical walls into horizontally juxtaposed compartments, only two of which are shown in Fig. 2, each wall supporting, on one side and in cantilever fashion, heat exchange tubes which are closed (except for small vent holes) at one end, but each tube is open at the other end which is flush with the other side of the wall. The liquid is sprayed from devices 8 so that it flows in filmform over the outside of the heat-exchange tubes, heating-medium is supplied to the interior of the heat-exchange tubes in the first compartment, and the arrangement is such that the vapour evolved from the liquid cascading down over the tubes on the left-hand wall of each compartment flows across the compartment through wire-wesh droplet-separator 7 and condenses inside the heat-exchange tubes supported on the opposite wall thereby boiling the liquid flowing down over the tubes in the adjoining compartment which is maintained at a lower pressure than the preceding compartment. The condensate runs down the tube-bores, is collected in troughs 10 and is then withdrawn from the shell through pipes 11. The vapour evolved in the last compartment flows to an external condenser. Some of the non-evaporated liquid 12, collected on the floor of each compartment, is sprayed over the heat exchange tubes in the next compartment. The heat exchange tubes may be shaped as in Fig. 2A, and may have vertical flutes in the surface of the bore and the outer periphery. The liquid to be distilled may be preheated, before it is introduced into the first compartment, by passing it through banks of heat conductive tubes which traverse the comparments in a direction counter to the liquid being distilled, so that some of the vapour condenses on the preheater tubes (Figs. 6 to 8, not shown). In the modified multieffect distillation plant shown in plan in Fig. 10, the compartments are separated by pleated sheets 52 of metal supported in parallel, vertical planes so that each sheet defines on one face an evaporator surface 52a and on its other face a condenser surface 52b. The sheets may be formed with vertical flutes. In a further modification, the pleated sheets may nest one within the other (Fig. 19, not shown).

Title: Oximeter and method for in vivo determination of oxygen saturatiion  in blood
IPC: G01N21/31
Filed: 1970-10-07
Abstract: 1325039 Blood oximeters R F SHAW 7 Oct 1970 47787/70 Heading G1A In a device for measuring the oxy-haemoglobin content of blood in a portion of human tissue, e. g. an ear 15, and in which the tissue contains N-1 other components which also have absorption coefficients which vary with wavelength, light passing through or scattered from the tissue is arranged to produce N+1 output signals each corresponding to absorption at one wavelength by one component, and these signals are combined to give an absolute measure of the amount of oxyhaemoglobin in the tissue. As shown, three electro-luminescent diodes 9, 11, 13 illuminate an ear 15 containing two absorbing species oxy-haemoglobin and (reduced) haemoglobin. Each diode emits a different wavelength, two of which are strongly absorbed by the two respective absorbing species, modulated at different frequencies. Light transmitted through the ear is received by three photo-cells 47-51, e.g. photo-multipliers or photo-diodes, each supplying a demodulator 53-57 tuned to one of the light source frequencies. The three demodulator outputs therefore represent the light absorption at the three incident wavelengths and are supplied to log gain amplifiers 23-27. The amplifier outputs feed a network of resistors 59-69 whose values are chosen empirically so that the output on the meter 43 represents the ratio of oxy-haemoglobin to haemoglobin, i. e. the oxygen content of the blood. The instrument must first be calibrated by introducing a number of blood samples of known different oxygen content into a suitable absorption cell, and choosing the resistors 59-69 to give "correct" readings on the meter in all cases. The demodulators may be dispensed with by providing each photo-cell with a different wavelength filter 52-56. Alternatively, a single detector may have its response to the different wavelengths separated out by synchronous demodulation at the three different light source frequencies, or by time sharing sequential operation of the sources. A single broadspectrum light source may be used with three filtered detectors, or with a single detector having associated therewith a filter wheel containing three different filters, the detecting cycles of the detector being synchronized with the wheel rotation. In this latter case, light guides convey light both from the source to the ear and from the ear to the detector. In a further embodiment a number of sources (91) in a circular configuration, Figs.3ab (not shown) irradiate a body portion and the light scattered from within the tissue is received by a number of detectors (47-51). A circular aperture (95) placed between the detectors and the tissue ensures that light both direct from the sources and also merely reflected from the tissue surface is not received by the detectors.
