Inventor: LEE M J
IPC: G01N31/22
Filed: 1979-03-27
Abstract: Method and apparatus for analyzing whole blood samples which feature impregnating a gel medium used for the analysis of the whole blood sample with an inert substance. When the whole blood sample is placed on the gel medium, the inert substance diffuses from the gel as the plasma solutes of the blood diffuse into the gel. The amount of the inert substance diffusing from the gel medium is inversely proportional to the hematocrit of the blood sample. In one embodiment, plasma solutes are caused to react with one or more reagents in the gel medium to assay various specific analytes. Also, the hematocrit, indicated by the diffusion rate of the inert substance from the gel, is determined and used to correct such assay.

Abstract: In a data processing system central processor units (10 and 10A), input/ output units (12), memory units (11) and secondary storage units (24, 25, and 26, 27) are interconnected by a bus (14). When one of the units, for example the processor unit (10), is to transfer information to a second unit, for example the controller (20) of the memory units (11) over the bus (14), the first unit, to prevent other units gaining access to the bus, generates a first signal onto a line in the bus (14) for a predetermined number of clock pulses, e.g. one cycle conflicting requests for bus access being resolved by priority arrangements. The second unit then takes over generation of the first signal on the bus line after the predetermined number of clock pulses up to the end of the transfer. <IMAGE>

Abstract: A fixed gating sequence apparatus and method for an inverter is disclosed. In one aspect of the invention, an outgoing signal of variable frequency is generated by the inverter in response to gating signals provided by an inverter control. The gating signals effectively are provided by a shift register of an inverter control to the gates of the conduction controlled rectifying devices in the inverter in response to a clocking signal. The clocking signal is provided to the clock input of the shift register at a normal system rate when an idle condition (idle control signal) is not present and at a predetermined cycling rate from when the idle condition occurs until a desired fixed gating pattern effectively is provided by the shift register to the inverter. The shift register remains at the stage providing the desired fixed gating pattern until the idle condition no longer is present, whereupon the normal clocking signals are again provided to the shift register. In another aspect, the gating signals, which effectively are normally supplied to the conduction controlled rectifying devices of the inverter, are blocked or inhibited from when the idle condition occurs until the desired fixed gating pattern is provided by the shift register of the control stage of the inverter. Thus, in this aspect, the inverter does not produce a moderate frequency burst of outgoing signal when the shift register cycles through and stops at the desired fixed gating pattern.

Abstract: A non-electric delay blasting method is provided which comprises the use of single trunk line of detonating cord having a series of detonating relays, all of the same delay period, connected at spaced intervals along its length. Branch lines of detonating cord are connected in groups to the trunk line in the intervals between the relays and each branch line has a delay detonator of the same delay period attached thereto. The delay period of the relays is shorter than that of the delay detonators. The detonators within the groups detonate in a random manner. The method eliminates the need to use large numbers of different delay period detonators in a multi-charge blast thus simplifying preparation of the charge and reducing inventories.

Abstract: To measure the extent of air flow, the pressure drop over two throttle components is used, the appts.having an easily removable filter. After the filter has been removed, a primary throttle component is put in its place in the appts., and during operation a pressure drop is measured over the throttle. The primary component is then removed, and is replaced by the secondary component which has a resistance different to that of the primary. During operation, a second pressure drop is measured over the throttle. The secondary throttle is removed and replaced by the filter which is repositioned. A third pressure drop is then measured over the filter. The extent of flow corresponding to the third pressure drop is determined through interpolation or extrapolation in relation to the first two pressure drops. (Provisional basic advised week 86/19)

Abstract: A barking machine has a container for processing logs formed with openings each extended lengthwise of the container, a transfer guide plate disposed between the openings, multiple notches formed in the openings, lower and side cylindrical rotators each having protruding barking blades on its outer periphery which pass through the notches, and a supporting member for retaining the transfer guide plate. In such a construction, the rotors are partially inserted into the openings, respectively. The lower rotor rotates so that its barking blades move toward the side opening, and the side rotor rotates so that its blades move upwardly. With this arrangement, it is possible to prevent the logs from being blocked between the rotators or falling from therebetween, and to provide a strengthened transfer guide plate with no deformation, thereby enhancing the circulating of logs in the container and the barking operation.
