Title: Blood pump
Inventor: LUNDBACK STIG
IPC: A61M60/876
Filed: 1985-03-15
Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Title: Residual current circuit breaker
Inventor: KNIGHTS DOUGLAS SYDNEY
IPC: H02H3/33
Filed: 1988-01-29
Abstract: A residual current circuit breaker apparatus includes a relay RLI with contacts RLI/1, RLI/2 closing on insertion of the load's electrical connector E, and the apparatus being tested, with the relay contacts opening, on removal of the electrical connector. The electrical connector E engages the rocker contact member of a switch SW to actuate the relay electronically. On insertion of the electrical connector E, operation of the switch SW causes a voltage to be delivered across the relay coil RLI which is sufficient to close the relay contacts. Reverse operation of the switch SW activates test circuitry R3, W4 to reduce the voltage across the relay coil causing the relay contacts to open. A coil W3 responds to loss of balance in the supply and to the test coil W4 by firing SCRI to de-energise relay coil RLI. Coil W4 is also responsive to live-neutral reversal. <IMAGE>

Title: Piezoelectric shear mode accelerometer
Inventor: WHATMORE ROGER WILLIAM
IPC: H01L41/113
Filed: 1988-11-02
Abstract: An accelerometer 49 consists of a plate 37 of piezoelectric material mechanically supported 45 at one end and bearing a pair of spaced electrodes 51, 53 on one of its two principal plane faces. The piezoelectric material is poled such that the polar axis 43 lies orthogonal to the plane of the plate 37. The arrangement of the electrodes 51, 53 and the polar axis 43 is such that this accelerometer 49 is relatively insensitive to the accuracy with which the polar axis 43 is aligned and is relatively insensitive to the generation of any pyroelectric charge resulting from a change in temperature. Sensitivity may be enhanced by increasing inertial mass load - for example, by attaching a loading mass (55, Fig 7) at or near to the free end. In a preferred arrangement, loading plates (59, 61, Fig 8) are mounted, one on each principal plane face. Those latter increase inertial mass loading and reinforce the plate structure to resist bending. The plate may be supported at both ends, to facilitate the wire bonding of electrodes. <IMAGE>

Filed: 1990-03-05
Abstract: A photo-counting type streak camera device determines by an integration of repeated measurements the probability distribution with time of phenomenon light such as fluorescence light which a specimen (3) produces upon reception of repeatedly generated pulsed exciting light (LB12). A phenomenon streak camera system (42, 92) time-measures the phenomenon light and a reference streak camera system (41, 91) time-measures reference light produced by the same pulse (LB1) from a source such as a laser 1. Both streak cameras are swept in synchronism by means of a common sweep circuit 8 triggered by a pulse (LB2) which is synchronous with the exciting light (LB1). An arithmetic unit (11) calculates the difference between outputs (91, 92) of the phenomenon and reference streak camera systems, thereby avoiding jitter or drift in the synchronism between production of the trigger pulse and the timing of the light detection caused by a power change of the pulsed light source (1). …<IMAGE>…
