Title: Mole plough supporting linkages
IPC: E02F5/10
Filed: 1972-06-02
Abstract: 1393456 Mole plough; tractor links HUDSWELL YATES DEVELOPMENTS Ltd 31 May 1973 [2 June 1972[ 25972/72 Headings A1B and A1P [Also in Division F2] A linkage for coupling a tractor to a mole plough such that the plough operates at an equilibrium working depth with respect to the tractor includes first and second interconnected members which are relatively vertically movable with respect to each other so as to restore the plough to its correct depth. The members are constrained in their movement by at least one pair of upper and lower sector shaped cams 36, 38 whose curved surfaces follow respective arcuate tracks 32, 33 formed by one of the members. In one form the first member comprises a cage like guide link 26 which forms part of a quadrilateral tractor coupling arrangement. Within the link 26 is located a floating box 30, that forms the second member which adjustably receives a coulter blade 16 to which the mole is connected. The blade is positioned within the box by adjustable studs (34) and pin (35) Fig. 5 (not shown). The box 30 has stub shafts 40 upon which upper and lower pairs of sector shaped cams 36, 38 are pivoted. The cams ride on the curved inner surfaces of the guide link 26 and are prevented from dropping under zero or low load by pins 42. Ram 48 holds the guide link 26 stationary with respect to the tractor such that an elevation of the tractor causes the cams to rotate anticlockwise. The resultant forces upon the stub shafts 40 exert a turning moment upon the blade 16 and cause it to raise the leading end of the mole. As the mole rises, relative movement between the blade 16 and guide link 26 is reversed such that the cams rotate clockwise. The cams are arranged such they are at the centre of their permitted rotational movement, and the geometric centre of curvature of the guide links curved surfaces corresponds to the apparent hitch point of the mole plough. Removal or introduction of the mole is accomplished by the ram 48 moving guide link 26 to an extreme upper or lower position. In a modification, Figs. 7-9 (not shown) the box 30 is mounted on the coulter blade and has forwardly projecting parallel faces which engage the opposed faces of a rectangular frame that replaces the cage like guide 26. One upper, and one lower sector shaped cam are mounted on stub shafts which extend between the plates and engage the opposed curved surfaces defined by the frame opening.

Title: Device for Draining Liquid from Wet Gas or Vapour.
IPC: B01D45/12
Filed: 1968-06-06
Abstract: 1,196,057. Steam traps. WATTS REGULATOR CO. 6 June, 1968 [14 June, 1967], No. 26951/68. Heading F4U. When liquid is present in a steam trap 12, a small gap 40 between a piston 36 and the wall of the trap is sealed by the liquid so that a sufficient pressure drop in the upper part 14 of the trap causes the piston to rise thereby lifting a valve member 46 to open a liquid drain outlet 56. When no liquid has entered the trap, gaseous communication through the gap 40 is sufficient to prevent raising of the piston. Wet gas enters the trap through an inlet 20 and liquid is separated centrifugally by means of fins 24. Gas leaves the trap through a filter 22 and an outlet 21. When the gas line downstream of the outlet 21 is closed, subsequent re-opening will cause a pressure drop in the part 14 of the trap, which drop will open the drain valve if liquid is present. Manual drainage of the trap may be achieved by screwing in a pipe 54 until passages 60 communicate with the interior of the trap.

Title: Apparatus and process for producing sphygmometric information
IPC: A61B5/022
Filed: 1975-06-26
Abstract: 1515924 Blood pressure parameter measurements AMERICAN OPTICAL CORP 26 June 1975 27097/75 Heading G1N(E) In an apparatus for measuring the diastolic pressure or the systolic pressure or the compliance of an artery in a limb 5, a varying pressure is applied by a pump 13 to a cuff 3. The resulting pressure variations due to the artery and the cuff is sensed by a transducer 21 whose output is differentiated 1. The pressure signal on line 27 and the differentiated pressure signal on line 30 are each investigated at a predetermined point in the pulse cycle determined by a comparator 27. The comparator senses when the differentiated signal changes sign, that is, at the systolic point. Diastolic pressure. This is determined by finding the pressure at which the differential of the same predetermined point of the pulse cycle is a maximum. Thus the differentiated signal is fed to a memory unit 33. Each time the comparator 27's output changes a timer 41 is actuated. The timer 41 causes a certain portion of the memory 33 determined by the multi-plexer 47 to be loaded via an averaging unit and an A/D converter 43 into a shift register 53. The timer 41 also causes the pressure signal to be loaded via an A/D converter 29 into a shift register 55. Successive portions of the shift register are summed and weighted 57 according to an appropriate algorithm and presented via a register 63 to a digital comparator 61. The comparator 61 determines when the differentiated signal has reached at maximum. At this point the register 63 is ordered by the comparator to load the output of the signal shift register 55 into a latch 65. Thereafter the pressure signal is converted from a binary signal to a binary coded decimal signal and is displayed by a read-out unit 73. Systolic pressure. This is determined by finding when the double differentiated pressure signal goes through a maximum. It is determined in a similar fashion to above Fig. 3 (not shown) except that the differentiated signal is fed through a further differentiator. Compliance of the artery. This is obtained from a plot of the differentiated signal versus the pressure signal in an "X-Y" recorder, Fig. 4 (not shown). Thus the outputs of A/D converters 43, 29 are fed via D/A converters to the two inputs of an "X-Y" recorder, whose pen is ordered to touch the paper by each timing signal. An integrator may also be connected so that a curve proportional to a plot of arterial volume versus pressure at the artery wall may be obtained through integration of the curve of the differentiated pressure signal versus the pressure signal.
