Title: Method and device for determining the perfusion efficiency  factor of animal tissue
IPC: A61B5/0275
Filed: 1974-01-29
Abstract: 1461345 Perfusion efficiency factor (blood perfusion and blood concentration)  L ESCHWEILER & CO 29 Jan 1974 03974/74 Heading G1N(E) In a device-for measuring the "perfusion efficiency factor" (p.e.f.) of a piece of animal tissue, the perfusion of the indicator is measured with the aid of one or more temperature sensors 11, 13. (The p.e.f. is a function of the rate of flow or perfusion I of an indicator - say blood with a radio-active tracer in it - flowing through the tissue, and a function of the concentration C of the indicator i.e. p.e.f. = F(I,C)). One sensor 11 is attached to a temperature controlled annulus 10 of good thermo-conductive material. In some cases Figs. 1, 2 and 4, Fig. 4 (not shown) a temperature sensor 13 is positioned centrally of the annulus so as to be in contact with the tissue. Thus by measuring the temperature difference between the annulus (which is maintained at a higher temperature than the body temperature of the tissue by a heating coil 12) and the temperature of the tissue at the centre of the annulus, a value of the perfusion of the indicator (blood) can be determined. A value can also be determined by measuring the amount of heat required to maintain the annulus 10 at a predetermined temperature above the body temperature. The indicator concentration can be measured with the aid of a radio-active detector 14, Fig. 1 (when a radio-active tracer is present). Alternatively the indicator cencentration may be measured polarographically, by a network of electrodes 23, 24, 25 and 26 imbedded in glass 22. The electrodes are in contact with an electrolyte which may be stored in a foil 28 surrounded by a gas-permeable membrane 27 to enable measurement of the local oxygen gas pressure given out by the tissue. The electrodes 23, 24 and 25 have small time constants and are located at the corners of an equilateral triangle Fig. 5 (not shown), the other electrode 26 which serves as a calibrating electrode and has a high time is located at the centre of the triangle. The electrical outputs of the two measuring instruments may thus be combined Fig. 6 (not shown) to provide a value of the perfusion efficiency factor. The entire measuring means is accomodated in a housing 15 provided with an annular groove 16 with support rings 17. The groove 16 is connected via a passage 16a with a nipple 18 to a vacuum pump to permit fitment of the measuring means to the tissue. The housing may also be provided with a flange 31 having adhesive members 31. The housing itself may be incorporated in an inflatable pressure exerting cuff D which can be placed around the human arm &c. Upon inflation the pressure exerted will locally interrupt the supply of blood so that the extent of skin breathing can be determined by the time derivative of the oxygen gas pressure.

[Class 114.] A variable pitch airscrew wherein the actuating gear includes two differential trains of wheels of opposite algebraic sign, is provided with control means which include brakes associated with the loose wheels of the trains and also frictionally-held members for holding the blades in set position when the controls are in the inoperative position. Mounted on the propeller boss 11 are two sets of epicyclic gears 3<a>, 8<a>, 9<a> and 3b, 8<b>, 9<b>, the diameter of the pinions being different in order to provide opposite relative motion when in use. The two trains are governed by braking members 12<a>, 12b, on the application of either of which a motion is given to the spur wheel 13 and this, by its engagement with the spur wheel 14 on the shaft 15 actuates a blade turning mechanism. The boss of the pinion 13 is screwed and engages a member 27 which slides in guides 31 and by means of a lever 29 communicates the position of the gears and thus the pitch setting to a rod 30 coupled to a pitch indicator. Each shaft 15 is normally braked by means of the parts 18 which are held by springs 19 in frictional contact with the brake surface 20 on the side of the pinion 14. For actuating the braking members 12<a>, 12b they are pivotally connected to a quadrant 72 on opposite sides of the centre 70 and the quadrant is geared to a rack 73 carried by the piston rod of a piston 74. Movement of the piston is controlled by a valve which may be controlled in turn by hand or by a centrifugal governor. The centrifugal governor may also be controlled by hand as to its position of equilibrium, this control being coupled to the engine throttle. The means for actuating the pitch indicating pointer may also control, by a direct drive or servomotor, the throttle valve of the engine carburetter or a valve on the air inlet or outlet of the engine supercharger, when the propeller blades pass through a pitch angle of zero value.

Abstract: 1457662 Gravity switches; centrifugal switches FA J A KRAFT OHG MASCHINENFABRIK 31 Jan 1974 [1 Feb 1973] 04522/74 Heading H1N [Also in Division D1] A high-speed stranding machine having spool carriers 3 journalled in a stranding motor 1 for supporting spools of the stranding material, the spool carriers having their centres of gravity such as to enable them to retain their normal orientation as the motor rotates, comprises a contact-closing device having a rolling contact maker such that deviation of the spool carrier beyond a predetermined angle from its normal orientation causes the rolling contact maker to close the circuit for an alarm and/or for stopping the stranding machine. In a first embodiment (Figs. 1 and 2) balls 15, 16 are accommodated in insulating bushes 17, 18 in the trunnion 4 of a spool carrier 3 which are angled as shown such that tilting of the spool carrier 3 (as in Fig. 3, not shown) causes a ball to bridge annular conductors 8a, 8b and close the circuit between leads 26, 27. Should bearing 5 seize up, for example, the carrier 3 rotates with motor 1 and centrifugal force causes both balls to bridge the rings 8a, 8b (as in Fig. 4, not shown). If the bearing 5 fails such that the axis 12-12 drops to 12<SP>1</SP>-12<SP>1</SP> the collar portion 14 of trunnion 4 directly interconnects the rings 8a, 8b. The insulating member 9 carrying the rings 8a, 8b and a cover 23 are flanged at 22 and 25 respectively to cooperate with recesses 21 and 24 in collar portion 14 and protect the rings 8a, 8b from ingress of foreign material. In a second embodiment (Fig. 6) the balls 15, 16 are in tubular conductive housings 17 and 18 secured on the carrier trunnion by a bolt (32, Fig. 5, not shown) to a bracket 30 on block 31 whereby the angle α is adjustable. On tilting or by centrifugal force one or both balls 15, 16 interconnect their respective housings 17, 18 to contact 34. Magnets 35 retain the balls in the operated position until released by depression of spring-biased pins 36. Connection to leads 33 is made on the axis of rotation of motor 1 by means of a rotary pin (38, Fig. 5, not shown) and a light (42) situated between the housings 17, 18 indicates which spool carrier is faulty. Cylindrical rollers may be used instead of the balls 15, 16.

Filed: 1966-05-24
Abstract: 1,154,355. Lamp holders. EASTMAN KODAK CO. 24 May, 1966 [24 May, 1965], No. 4563/69. Divided out of 1,154,352. Heading H2E. [Also in Division G2] A photographic camera (20) (Fig. 1, not shown), having a rotatable socket (23) for a flash cube (24) is further provided with means operatively connecting the film wind and shutter cocking mechanism with socket drive means so as to tension the drive during film wind, the drive means running down to rotate the socket after an exposure has been made. A flash cube is inserted in the socket so that the centre post (28) of the flash cube receives a stabilizing spindle 56 (Fig. 8), of the socket, two V-shaped retaining springs engage a pair of lugs on the centre post, and the base of the flash cube depresses a control pin (60) (Fig. 3, not shown) to automatically adjust the diaphragm aperture and the shutter speed for flash operation. An unexposed film frame is moved on to the picture taking axis by turning a lever 30 to the position shown in dotted lines. Rotation of this lever rotates the film take-up spool (not shown) by means of gearing 33, 34 and also cocks the shutter by means of a foot 35 cocking a shutter striking plate 36. Simultaneously, a socket driving ring 100 is rotated 90 degrees counterclockwise (Fig. 8) by means of a hook 102 of a winding arm 50 engaging a pin 101 of the ring 100 and rotating it to the dotted line position shown against the bias of a helical drive spring. At the end of this rotation, the ring 100 is held in position by engagement of a tab 106 of a lever 107 with the skirt 108 of the ring 100, the lever 107 being held in position by engaging the plate 36. During rotation of the ring 100 a tab 115 of an indexing lever prevents rotation of the socket assembly (23) and an inserted package. The winding lever 30 is then returned to the solid line position by a spring 47. In making an exposure, a member 31 is depressed to the position of Fig. 10, thereby releasing the striking plate 36 to strike an ear 45 of the shutter blade, which thus uncaps the diaphragm aperture. The plate 36 also strikes a switch 97 to complete the flash circuit. Depression of the member 31 also causes an extension 121 thereof to move the tab 115 downwardly out of a notch 116 of the socket assembly (23). The socket does not rotate since a stop surface 109 of the extension 121 prevents the lever 107 from rotating out of engagement with the ring 100. After exposure, the upward movement of the member 31 disengages the surface 109 from contact with the lever 107 which therefore rotates out of contact with the ring 100, which in turn rotates clockwise (Fig. 8) carrying with it the socket assembly (23). An arm 123 engages the next succeeding notch 116 and prevents the socket rotating through more than 90 degrees. When the member 31 is in its up position and the socket assembly fully indexed, the tab 115 enters said succeeding notch 116, thereby displacing the arm 123 to take up the position shown in Fig. 10.

Filed: 1941-04-05
Abstract: 546,939. Cable grips. WILD & CO., Ltd., M. B., and WILD, S. C. April 5, 1941, No. 4574. [Class 78 (ii)] In haulage rope grippers of the type having a pair of jaws with an operating lever in between, the lever m is of bell-crank or equivalent form pivoted at f to the jaws a. Side projections h at the rear of the lever m engage shallowing grooves on the inner faces of the jaws to press these apart above a connecting bolt b when the lever m is depressed. This action forces the lower parts of the jaws together to grip the cable d in longitudinal channels. The cable d is held down by the spokes j of rotary members located at intervals along the track, and impact of the vertical short arm n of the bell-crank m with these spokes serves to tighten the grip of the jaws on the cable. A stop p formed with steep wedge abutments serves to impart this final pressure more heavily, and a further stop q provides a final limit to the downward movement of the lever m. When the lever is swung up to inoperative position the projections h enter holes o in the jaws a. Specification 474,330 is referred to.
