Abstract: A protector for a light tube, particularly an ultra violet sun bed lamp or fluorescent lighting tube is made of a flexible plastics material such as PVC, acrylic or polyethylene and encloses the tube, making contact with it at least at spaced positions, so as to contain any glass fragments if the tube should shatter. Several embodiments are described including the use of loose polyethylene sleeve (l0) retained by circlips (l3) or an extruded acrylic tube (l4) having internal ribs (l5) providing partial spacing from the surface of the light tube (ll), the acrylic sheath being extruded over sized and shrunk onto the light tube by the application of heat applied either externally or using the tube itself as a heat source. In an alternative form, a flexible PVC sleeve (l6) is expanded by compressed air so that the light tube (ll) can be inserted, the sleeve then retur­ning to its normal size. In a further alternative, a self-shrinking material such as cellulose is used in extruded form, soaked in water to expand it onto the light tube and dried to shrink onto the surface of the tube.

Abstract: The construction consists of a multilumen cannula with a biopsy channel (1), which comprises the full cross-sectional diameter of the cannula, and one or more side channels (2); (2a, 2b) which are used for the application of substances and which communicate with the biopsy channel in the area of the cannula tip (Fig. 1:1). The arrangement of the channels (1, 2, 2a, 2b) guarantees a maximum cross- sectional diameter of the tissue samples with a minimum cross- sectional diameter of the needle. In the design in which the cutting end of the biopsy device is formed solely by the wall of the biopsy channel (Fig. 9:1) cut at an acute angle, and the application channel (2) formed by a tube pushed eccentrically over the biopsy channel does not extend as far as the cutting end, on the one hand the tissue is cut during the biopsy procedure without being damaged by the application channel (2), and on the other hand the application channel (2) with only a displacing action is not blocked by tissue. The application system is controlled automatically by the puncturing procedure via a contact mechanism (5, 6). By means of this invention, it is possible to significantly shorten the time of the operation for removing tissue and applying substances. In this way, complications in the context of biopsy can be avoided, and the indications for biopsy can be extended. <IMAGE>

Abstract: A clutch control system provides and regulates pressure at a clutch (28) for a transmitting torque from an engine (12) to a drive train (30,32) through a continuously variable transmission (18). A positive torque value is determined for each throttle setting and provided as a pressure input signal (62). Engine speed is monitored through a closed loop feedback system (68) to provide an error signal (on 106) to the desired pressure setting. A pressure control loop (110) monitors pressure at the clutch through a closed loop feedback system to maintain the pressure at the clutch at a desired level. Filtering (74,92) is provided in the torque and engine speed loops to provide for a more realistic response to driver demand. Incorporation of belt ratio factor (82) in the engine speed control loop further provides for consistent and accurate response to driver demand variations at differing trans­mission drive levels. Overall line pressure within the associated hydraulic system further controls a proportional gain in the pressure control loop to provide appropriate response. Phase compensation and integral dynamic phase factors in the pressure control loop further guarantee a zero level steady state error signal and the generation of accurate control over the pressure control valve.

Abstract: A high pressure foam slurry generator (10), including a source of slurry, a source of gas, and a means for combining the slurry and the gas, which is usually nitrogen. A housing (36) receiving the slurry and the gas has a connector (40) with multiple channels. One channel (42) for the nitrogen gas acts as an inlet and has a bushing with a series of multiple holes through which the nitrogen gas is broken into a plurality of high velocity streams. The slurry with a foamer agent added combines at right angles with the nitrogen gas and is foamed before being pumped through a tubing string into a gas or oil well (14). Also included herein is a process for making foamed slurry by pumping a slurry capable of being foamed to a housing, pumping nitrogen to the same housing, separating the nitrogen into a plurality of high velocity streams, and combin­ing the streams and the slurry in a foaming action. Either the slurry or the nitrogen may have two sepa­rate streams entering the housing as right angles to each other. All of the streams are normally combined at right angles to obtain the proper amount of foaming action.

Abstract: A test kit is used in an agglutination immunoassay to determine a multivalent immune species, such as Streptococcus A antigen, in a biological sample. The method includes contacting an aqueous solution of the species with an agglutination indicator reagent having receptor molecules reactive with the species to form an agglutinate of the reaction product of species and receptor. These receptor molecules are bound to polymeric particles which contain tracer molecules. The resulting agglutinate is captured on a microporous membrane which has an average pore size which is at least five times greater than the average diameter of the polymeric particles. Unagglutinated residual materials are washed through the membrane using a wash solution. This solution has a pH of from 5 to 10 and an ionic strength of at least 0.25. Tracer is then determined either in the agglutinate or in the residual materials. The test kit includes the agglutination indicator reagent, the wash solution, and optionally an extraction composition.

Abstract: A horizontal phase detector of a television apparatus receives an analog composite video signal (130) that is sampled and digitized at a rate determined in accordance with a clock signal (CK). The leading edge of a simulated sync pulse signal is computed from the digitized signal using interpolation. The phase detector also receives a second signal (OSC) that is indicative of a transition edge of a horizontal oscillator signal. The timing of the transition edge is contained in first (MS) and second (SK) signal parts. The first part (MS) is a periodic signal having a transition edge coincident with that of the clock signal (CK), and the second part (SK) is a skew signal that represents a fraction of the period of the clock signal (CK). The leading edge of the computed sync pulse signal is phase-compared with the oscillator transition edge to generate a phase difference signal (PH) for synchronizing horizontal oscillator operation.

Abstract: The present invention is directed to the construction of an integrated circuit chip, and to the method of making such a chip from a plate or wafer. In accordance with the present invention a chip is formed to have conductive edge portions disposed on an insulator surface, which portions optionally may further be expanded into a pad (22). The insulating material electrically isolates the conductive edge portions from the semiconductive body (23) of the chip. The invention may be implemented in redundant fashion to effect a multiplicity of electrical connections to a set of bulk semiconductor integrated circuits formed on the wafer. 
     Each exposed conductive portion on a chip edge and its optional surrounding conductive pad may be reliably surrounded by insulator so that electrical shorts to non-insulating regions are not experienced. By this edge surface structure integrated circuit elements may be stacked in an array (13), electrically connected at the edge surfaces (19) thereof, without hazard that any electrical regions of the integrated circuit elements may be contacted, save intentionally through a conductive lead (18) or film connected to the pads (22).

Abstract: A process for separating upgoing (45,47) and downgoing (41,43) seismic wave events in a vertical seismic profile, and particularly for vertical seismic profiles wherein the seismic energy source is offset from the borehole in which seismic detec­tors are located in vertical spaced array. The process operates on two detector signals at a time (as S₁ and S₂) and is based on the concept that waves traveling in opposite directions have spatial derivatives of opposite sign. The derivative is approximated by the difference of the two signals which is time integrated to recover the phase. The resulting integrated difference signal I is then amplitude scale corrected and combined by addition or subtraction with a signal S o  representing the sum of the two detector signals to form a succession of filtered signals which, when recorded in alignment in order of detector depths to form a vertical seismic profile preserves either the upgoing or the downgoing seismic events.
