Abstract: A method and an apparatus for separating proteins or other amphoteric mixtures into their component parts by utilising the fact that the degree of adsorption by a certain adsorbent per component is dependent on the prevailing pH in which the material is transported through an adsorption column or over an adsorption-­bed. To that end the pH is varied by the diffusion of an acid or basic gas such as CO or NH in the adsorbent in a direction transverse to the liquid-transporting-direction, such, that the components are separated from the mixture in a sideways direction. The pH-regulating agent preferably is adminsitered via a membrane.

Abstract: A pulse oximeter or plethysmographic device utilizes light varying in intensity at a predetermined carrier frequency. A passive resonant circuit 47 having a resonant frequency substantially equal to the carrier frequency is connected between the photodetector 22 and the first amplifier 46. The resonant circuit 47 serves to suppress spurious DC and low frequency components such as those due to ambient light and ambient light flicker and also to suppress high frequency interference. Because ambient light signals are suppressed, there is no need for dark current correction or restoration. Suppression of ambient light and other interference upstream of the front end amplifier avoids saturation of the amplifier and permits use of a front end amplifier having high gain.

Abstract: A lubricating oil composition prepared by incorporating (A) 0.05 to 5 wt % of an alkenylsuccinic acid ester and/or an alkylsuccinic acid ester and (B) 0.005 to 5 wt % of a fatty acid ester of a polyhydric alcohol in a base oil. This composition has low frictional characteristics, i.e., a small ratio of the static friction coefficient to the dynamic friction coefficient and gives a less shock upon gear changes. In addition, it undergoes less changes in frictional characteristics with the temperature change or with the lapse of time. Therefore, it is well adapted for reduction in the size of, for example, a transmission.Thus,the lubricating oil composition is extremely effective as the lubricating oil for an automatic transmission, a part having a wet clutch or wet brake of, for example, tractors, and the like.

Abstract: The invention relates to an arrangement of a semiconductor component (1) suitable for surface mounting and a process for surface- mounting it on circuit boards. Characteristic feature of the new arrangement is that the connection strips (3) are supported by a semiconductor chip (2) itself which is present in the arrangement, with the result that the Kapton frame which hitherto has been standard can be dispensed with. In addition, the ductile connection strips (3) are bent through an angle of 90 DEG  with respect to the principal phase (4) of the semiconductor chip (2), with the result that all in all a substantially smaller design and consequently a higher packing density is possible compared with the TAB versions hitherto standard. For the purpose of surface mounting this new arrangement (1), the semiconductor chip (2) is placed on the circuit board (7), with the result that the ductile connection strips (3) are deformed and contact is reliably made to the connection paths on the circuit board. The surface mounting can be carried out with conventional SMD installations. <IMAGE>

Abstract: The invention relates to a method of determining the porosity of an underground formation being drilled by a rotating drill bit mounted at the lower end of a drill string. The torque (TOR) and the weight (WOB) applied on the bit when drilling the underground formation are measured; the effect of the geometry of the drill bit on the torque and weight on bit response is determined; the porosity (phi) of the formation being drilled is derived from the measured TOR and WOB taking into account the effect of the geometry of the drill bit. 
     Preferentially, the porosity phi is determined from the following equation: 
TOR = (k₁ + k₂.phi) WOBª 
where k₁, k₂ and a are parameters characteristic of the geometry of the drill bit.

Abstract: In order to reduce noise generated by a flow stabiliser (17) responsive to mains pressure on the input conduit of a solenoid valve (1), an insert (18) is fitted into the conduit between the stabiliser and the valve. The insert provides an intermediately sized aperture (23) which is smaller than the flow regulator output aperture, but larger than a restricted section flow path (24) also provided in the insert. A flange (21) of the fitted insert may be pressed between the flow regulator and a radial projection (32) from the inner conduit wall. The same projection may have an axial extension, which contributes to sealing the diaphragm (11) of the valve (1). The diaphragm may have a flap or moving seating (7), which projects into the flow path just downstream of a wall (31) forming part of the fixed seating (6), which receives the flap, and also transverse to the general axis of the flow path. The latter is thus constrained to zigzag, which cooperates with the silencing action of the insert (18).

Abstract: An improved liquid flow distributor assembly (48) for a process column (10) of the type wherein the distributor is positioned above a packing section (14) for the distribution of liquid downwardly therethrough. The improvement comprises a plurality of troughs (49) constructed with a series of removable distributor tube assemblies (62) on opposite sides thereof. Each tube is constructed with a first generally U-shaped securing, or mounting channel (64) affixed to the side of a distributor trough with a hole (56, 58) formed therethrough in flow communication with the lower region of the trough. An angulated distributor channel (72) is constructed for slidable engagement with the U-shaped securing channel element. The sidewalls of the U-shaped channel are constructed for securing the sliding channel therein and forming a triangular flow conduit for receiving the discharge of fluid from the trough. The tubes depend downwardly from the side walls of the trough below the bottom region thereof so as to reduce disturbance by the rising vapor flow at the point of liquid discharge. In this manner the advantages of distributor tubes are provided in a configuration facilitating the cleaning thereof by removal of the sliding channel member from the securing channel element.

Abstract: The invention belongs to the technical area of medical technics and devices for radiation treatment of cancer tumours. 
     At radiation treatment of cancercells one is destroying not only the cancer tumours but also other parts of the body and therefore there exists problem with creating methods and devices that will only destroy the cancercells and not damage the rest of the body. 
     As contribution to the solution of this problem is suggested this method and device. 
     By physics experiment, awarded with Nobel prize in physics, is known that according to the laws of symmetry matter situated before a mirror gets a double of antimatter at the same distance from the mirror (which is symmetry axis) behind the mirror. 
     The theory of the inventor is that if one by radiation destroys the antitumour (the double) which is of antimatter and is situated behind the mirror, one will because of the symmetry also destroy the cancer tumour which is of matter and is situated in the body at the exact distance from the mirror as its double. 
     With the description is illustrated the idea of the invention; The patient 1, with the cancer tumour 2, is fixed at a table 3 before the mirror 5. At the same distance from the mirror 4 is the double of the cancer tumour 2A which is irradiated by the beam 5 after that the computer 6 has estimated the exact symmetric location for irradiation behind the mirror.
