Title: Blood Circulating Apparatus.
IPC: A61M60/851
Filed: 1967-11-21
Abstract: 1,187,080. Blood circulation apparatus. BORG-WARNER CORP. 21 Nov.,. 1967 [17 Feb., 1967], No.52935/67, Heading A5R. [Also in Division F1] Blood circulating apparatus comprises three vertically disposed compartments 7, 10, 11, a port 8 in the upper compartment for introducing blood thereto, first and second check valves 12, 13 providing fluid communication between the compartments, a first blood conduit 14 for conveying blood from the lower compartment to the patient, and a second blood conduit 16 for returning blood from the patient to the upper compartment, there being a source of gas pressure 49 selectively communicable with the intermediate compartment through a control valve 37 and also in continuous communication with the lower compartment through a conduit 59 thereby to provide pressure which causes blood to be delivered to the patient. As shown, the apparatus also includes a gas flow regulator 53, a gas flow meter 58, a variable blood flow restrictor 15, a priming valve 60, and a sensing device 17 (see also Figure 5, not shown) which actuates one of two trigger valves 28, 29 depending on the pressure in the lower compartment. It is stated that one of the compartments 7, 10, 11 may include a blood oxygenator device. The apparatus operates cyclically through two stages, a first stage (Figure 1) in which blood is pumped from the lower compartment and returned blood collects in the upper and intermediate compartments, the valve 12 being open and the valve 13 closed, and a second stage in which, with the valve 12 closed and the valve 13 open, the return blood collects in the upper compartment and the blood in the intermediate compartment drains through to replenish that being pumped from the lower compartment. Transition from one stage to the other is effected when the sensing device 17, sensitive to the pressure in the lower compartment, triggers open either valve 28 or 29 which allows gas pressure from a conduit 57 to move (through conduit 61 or 63) the control valve 37 so as to selectively vent or pressurize the intermediate compartment. The sensing device 17 (see also Figure 5, not shown) comprises a diaphragm (24) in communication with the compartment 11 and arranged to move, when the pressure in the compartment rises, a rod (26) engaging a rocker arm 30 which engages in turn one or other of the valves 28, 29. The rocker arm is adjustably spring biased (36) against movement of the rod.

Abstract: 1393369 Liquid transfer expandable boom J D DUGGAN 16 Nov 1972 [16 Nov 1971] 53239/71 Heading B8E [Also in Division B7] An expandable boom for transferring liquid between ships or other relatively movable tanks comprises a linkage in zig-zag form in plan, Fig. 1, articulated or vertical axes on supporting frames 7 and normally urged to extend by tension on a cable 10 exerted by a winch 9. Crude oil pipes 3, Fig. 2, are connected by U-shaped pipes 4 secured to the frames 7 and fuel oil or other auxiliary pipes 5 are similarly joined by pipes 6 or these pipes may be replaced by tie bars 8. The boom can be retracted to its collapsed state, Fig. 3, by a winch 15 connected by a cable 16 to an anchorage at the pillar 14 at the remote end of the boom which in turn is supported by a jib 21 when connected to the ship 2. In a modification, Figs. 5, 6, the boom is mounted on a moored buoy 30, also provided with port and starboard mooring cables 43, 44 by rams 35 engaging a collar 34 on the first boom frame 7 to take up relative movement. To permit extension of the boom and mooring of the ship an additional cable 36 extends from a remotely controlled winch 37 joined to a float 39, Fig. 6, by a rope 38 which can be taken on a ship and drawn in with a ballclamp 41 then engaging a sleeve 42 to bring in the mooring cables 42, 43 which when secured allow the clamp 41 to be released so that further winching in engages another clamp 46 with an eye 47 on the pillar 14 to bring it in for connection to the ship. This boom is also retracted by a winch 15.

In a fading and mixing arrangement, colour television signals 3 and 4 according to the N.T.S.C., P.A.L. or SECAM standards are applied via terminals 1 and 2 to simultaneously operated fader stages 7 and 8, the whole of the signals passing to fader 7 but only the colour synchronizing " burst " components 3<SP>1</SP> and 4<SP>1</SP> being allowed to pass to fader 8 by appropriate control of gates 5 and 6. Fader 8 is a cross-fade circuit which produces an output of constant amplitude made up of inversely varying proportions of the input signals, whilst fader 7 may comprise a similar circuit, a circuit for producing a " rolling cut " (i.e. a circuit in which one signal is substituted for the other over an adjustable area), or a circuit selectively operable to produce a cross-fade or " rolling cut." The output from the two faders are combined in an adding stage 11 to produce an output signal at 14, the connection from fader 7 including a gate 9 which is controlled to transmit only the picture signal component 3<SP>11</SP>, 4<SP>11</SP> and the scanning synchronizing component 3<SP>11</SP>, 4<SP>11</SP> The output signal thus comprises the mixed or faded signal components from fader 7 together with a constant amplitude synchronizing component from fader 8.

Filed: 1971-12-08
Abstract: 1362047 Photo-electric detection of defects NIPPON KOKAN K K 8 Dec 1971 56909/71 Heading G1A Surface defects in a moving body, e.g. a steel strip are detected by repetitively scanning sequentially at least two beams of light across the strip, detecting reflected light, delaying the detected signal for each scanning beam (except the last beam) by the time interval between it and the last of the scanning beams, to match the time phases of all the signals, and indicating the presence of a defect only when all of said signals exceed a predetermined amplitude level. Fig. 1 shows a projector producing two beams spaced in the direction transverse to the movement of the strip 1. A mirror drum 3 scans the beams across the strip. The photo-electric detector (4) output is amplified at 5 and defect signals detected by discriminator 6. The defect signals due to different beams are combined at G after delay of the earlier one at 7. A pulse shaper 8 feeds relay 9, which operates buzzer 10, lamp 11 and/or a recording meter 12.  Instead of a scanning beam arrangement as in Fig. 2, the beams may also be slightly spaced apart in the direction of movement of the strip. The system is designed to avoid the effects of sudden noise variations due e.g. to the variation of the supply voltage.
