Abstract: 1419701 Determining the oxygen content of blood OXIMETRIX Inc 31 Jan 1973 [1 Feb 1972] 4850/73 Heading G1A In an apparatus for determining the oxygen content of blood employing a disposable catheter 8, two alternately pulsed light sources 11 and 12 emitting different wavelengths # 1  # 2  (light emitting diodes) are arranged to direct their radiation along respective guides 13, 14 of a bi-furcated light guide to be received by an optical integrator 6 a diffusing element (which ensures that radiation leaving its outlet end 6A is uniformly distributed over its outlet area) to be received by a transmitting fibre optics guide 9 of the disposable catheter and, the backscatter radiation is received by a further guide 10 and directed on to a detector 16. The detector 16's output is fed via an amplifier A1, whose bias is checked and controlled (if necessary) by a further amplifier A2, to a resistor capacitor and amplifier network 17, 19, 20 or 22, 23, 24 to produce a continuous voltage directly related to the intensity of the backscattered radiation for the wavelength concerned. The operation of the "resistor-capacitor-amplifier networks" and biasing amplifier A2 are controlled to operate in sequence by a pulse generator 15 with switches S1, S2 and S3 as shown. The outputs of the amplifiers 20, 24 are fed along with reference signals (terminals 28, 32), as shown in Fig. 2, to two sets of resistance networks 26, 27, 28 and 29, 30, 31 for producing two anologue voltages representative of the numerator and denominator of a ratio which is directly proportional to the oxygen saturation of the blood being investigated. The description discusses this ratio at length. The ratio, once formed by a ratio logic circuit 35 is displayed directly on a digital panel meter 36. In a modification a pair of fibre optic catheters is used each with associated circuitry, are being inserted in a systemic artery to measure arterial oxygen saturation, the other being inserted in the right heart or pulmonary artery to measure mixed various oxygen saturation and the difference between the two readings provides a measure of the heart's efficiency.

Title: Improvements in hydraulic mechanism for controlling clutches
IPC: F16D25/062
Filed: 1924-02-27
Abstract: 232,734. Bray, W. Feb. 27, 1924. Clutches, friction; controlling variable-speed and reversing gearing. - A series of hydraulic cylinders and plungers for selectively operating the clutches of a variable-speed gear are mounted to turn with the driving-shaft, which carries also the means for selectively actuating the plungers. As applied to a variable-speed and reversing gear, each clutch V is connected by a passage U in a sleeve on the driving-shaft I to a radial hydraulic cylinder T. Spring-pressed plungers T<1>, furnished with rollers Z engaging grooves Z' in the cylinders, are actuated by sliding cams 0, so disposed in relation to the cylinders, as shown in Fig. 5, that only one can act at a time. The cams are carried on a loose sleeve L, either where shown in full or in broken lines, and may have slight depressions at their crests to receive the rollers. A second sleeve N, slidable on the shaft I, is coupled to the sleeve L by a pin L<2> and helical groove L<1>. A universally-pivoted lever A, moving in a gate B, is connected by a ball joint D to a block E, which is dovetailed to a bar J and is provided with terminal teeth I' to engage teeth G on a bar H dovetailed to the bar J. The bars H, J carry respectively forks K. M. for actuating the sleeves L, N. As the lever A is moved along the central track B<1> of the gate it slides the parts J, N and so turns the cam-carrying sleeve L. On deflecting the lever to the left or right for a forward or reverse gear, the teeth F, G engage and a notched projection P on the block E in engagement with a bar Q on a pivoted lever R, moves the upper end of the lever R clear of a lug S on the bar H. Movement of the lever A along a side track B<2> of the gate then slides both sleeves L, N and actuates the selected plunger T' and clutch V. A compensating-reservoir X communicating with the cylinders T by a valve chamber Y<1>, non-return valves Y, and passages W, is provided with a piston X<1> carrying a hollow piston rod and filling-funnel X<3> having a stopcock X<4>. When the reservoir X is empty, the cone X<2> closes the passage to the chamber Y<1>. In place of the valves Y, the plungers themselves may control the passages to the reservoir, the cylinders all being in communication with one another when the plungers are inoperative. The passages U may be drilled in the shaft itself or in an enlargement thereof. The Provisional Specification describes means for actuating a single clutch; the use of bell-crank levers, which may carry antifriction rollers, for conveying motion from the cams to the plungers; and such arrangement of the cams or bell-crank levers that the plungers are successively actuated as the cam-sleeve is advanced, the operating-lever being adapted to be arrested at appropriate positions in its quadrant by notches &c.

A friction disc 38 is preferably interposed between the clutch plates 30, 31. As shown, the shaft 19, which is rotatably mounted in a wringer supporting post 13, is coupled to the shaft 24 through a bevel gear 22 and gears 23, 23 on the two shafts respectively, the gears 23 being loose on the shaft 24 and provided with detents 25 for engagement by corresponding detents on a sliding clutch member 27 which is splined on said shaft and is actuated by a handle 28b having means 28c for locking it in a forward, reverse or neutral position.
Patent GB-470772-A (GB)
Title: Method of making artificial lumber
IPC: C08L97/02
Filed: 1936-02-20
Abstract: Artificial lumber, wall boards, and the like are manufactured by mechanically disintegrating in the wet state natural raw uncooked woody material, without the use of high temperatures and pressures, to produce a wet mass of fibres, incorporating therewith a binder consisting of synthetic-resin-forming ingredients or of a partial condensate thereof in an aqueous medium, draining the mass to obtain a felted mat of fibres, partially drying the said mat and hot-pressing.  Suitable woody materials are sawdust, chips, shavings, and trimmings from veneer plants.  The binder may be prepared from phenol, m-cresol or crude carbolic or cresylic acid, with or without urea, and formaldehyde, polymers thereof, or hexamethylene-tetramine. After incorporation of the mass with the binder there may be added a mineral acid, e.g. hydrochloric or sulphuric acid, or a salt of acid reaction, e.g. aluminium sulphate, to precipitate the partial condensate; or waterproofing materials, e.g. waxes, pitches, wax tailings.  Before draining, the mix may be passed through a Jordan. The partial drying may be carried out, e.g. by suction or pressing. In examples, binders are prepared from cresylic acid and formaldehyde with or without urea, in aqueous solution (which may also contain denatured ethanol, methanol, triethanolamine, oleic acid) in the presence of condensing agents such as caustic soda, caustic potash, ammonia, sodium arsenate, sodium sulphite, lime water, and barium, magnesium, manganese, sodium and zinc acetates; in example 5, saponified linseed oil is an ingredient. Specification 28155/10, [Class 2 (iii)], is referred to.

Title: Improvements in or relating to door positioning mechanism
Inventor: BARNETT EUGENE JASPER
IPC: F24C15/02
Filed: 1955-02-22
Abstract: 765,266. Door-operating appliances; springs. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 22, 1955, No. 5221/55. Classes 65 (1) and 65 (2). [Also in Group XXXII] An oven door 10, pivoted about a horizontal axis 20 adjacent to its lower edge, is provided with means whereby a spring 44 holds it closed, retains it resiliently in a slightly - open position, and counter-balances it during further opening; the weight of the door preferably overcomes the counter'- effect of the spring in the fully-open position. In the arrangement shown, the door has fixed to it a blade 40 with cam surfaces 57, 58, a hook 42 and a stop lug 79, and the spring, anchored at its lower end, is attached at its upper end to a rod 50 having a hooked portion 48 engaging over the inner end of the blade and an abutment 78 to engage the lower end of a yoke 64 which carries a roller 60 engaging the cam surfaces 57, 58, the roller being guided by a fixed slotted member 66. In the closed position shown, the roller is pressed by the spring against the cam surface 57 to hold the door against opening; after a slight opening movement by hand, the roller passes on to the cam surface 58 to exert an opening force, but the hooks 42, 48 having come into engagement, further opening causes the blade to extend the spring and lifts the rod 50 through the yoke 76 rendering the abutment 78 ineffective, so that there is a partly-open position of the door in which the door remains stationary since movement towards the closed position is opposed by the spring acting through the yoke 64, roller 62 and cam surface 58 and further opening is opposed by the spring acting through the hooks 42, 48, the latter effect providing a counter-balance during the remainder of the opening movement. In a modification, Fig. 5 (not shown), the yoke 64 is replaced by a pivoted bell-crank member with a horizontal arm on which the abutment 78 rests and a vertical arm carrying the roller, the cam surfaces 57, 58 being formed near the lug 79. Hinges.-The door 10 is pivoted at 20 to a pair of hinge brackets 21, each having a vertical portion 22 adjustably fixed to the front plate 14 of the oven by a screw 30, with a bowed spring 36 interposed between the members. The lower end of the portion 22 rests against a lead spring 26 fixed to the plate 14.
