Title: Positive displacement diaphragm pumps employing displacer valves
Inventor: LINDNER GEORG HEINRICH
IPC: F04B43/06
Filed: 1984-12-07
Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.

Patent PT-87739-B (PT)
IPC: C12Q1/6825
Filed: 1988-06-16
Abstract: A method for detecting a first member of a specific binding pair in a sample, the first member being capable of forming a complex with a second member of the specific binding pair, includes immobilizing the second member on a surface of a piezo-electric crystal oscillator, determining a first vibrational frequency of the oscillator on which the second member has been immobilized, contacting the surface of the oscillator on which the second member has been immobilized with the sample under conditions permitting formation of the complex, and with a mass increasing particle under conditions permitting binding of the particle with the first member, mass coupling the bound particle with the oscillator, and determining a second vibrational frequency of the oscillator with which the particle has been mass coupled, the difference between the first vibrational frequency and the second vibrational frequency providing a measure of the quantity of the first member in the sample. In an alternative method a particle binding member is used, having two binding regions capable of binding to the first member and the particle, respectively. 
     Because the mass of each particle is relatively greater than that of the member, the mass coupling on the surface effectively amplifies the mass increase owing to the specific complexing.

Title: Process for the preparation of a methyl polysiloxane liquid with an improved resistance to the thermal rearrangement of siloxane
Inventor: HALM R L
IPC: C08K5/13
Filed: 1980-01-03
Abstract: Terminally blocked methyl polysiloxane liquids such as trimethylsiloxane-end-blocked polydimethyl siloxanes can be made more resistant to the thermally induced siloxane rearrangement by incorporating in them titanium, zirconium or hafnium compounds. These compounds can be incorporated by admixing the organosiloxy derivative of titanium, zirconium or hafnium to the said liquid, or by admixing certain organic compounds of titanium, zirconium or hafnium to the liquid, and heating the mixture in order to decompose the organic compound introduced. The thermal stability of the liquid can be further improved by admixing a small amount of an organosilicon hydride to the titanium-, zirconium- or hafnium-containing liquid. Such thermally stabilized liquids are particularly suitable for use as heat transfer agents in a non- oxidative water-free environment.

Title: A multi step method for photographic halftone copying
Inventor: LENNMARK INGE
IPC: G03C5/00
Filed: 1982-01-26
Abstract: To be able to control the contrast in photographic copying, especially for colour, it is desirable to let the whole of the original's tone spectrum be used whilst not overstepping the copy material's full tone spectrum.Contrast regulation has so far been carried out using three different techniques, either in combination or on their own:1. copying via an intermediary original2. copying through a half transparent mask, which is adapted in contact with the original3. prior illumination of the copy material with white light.Contrast control with the help of the shadow mask method occurs via:- exposure of the copying material is divided up into two or more steps,- each exposure step involves a definite part of the original's scale of tone which can then be controlled for suitable lighting on the copy- those parts of the original scale of tone which are not included in a defined exposure step are shaded by a photographically produced mask which is totally opaque in those parts of the original's scale of tone and transparent in the other parts.- the mask is produced via exposure of a defined area in the light path of an optical copying arrangement (enlargement unit), is developed and put back in the exact same spot.- the mask represents a picture of non-definition in this part of the light path.- the mask's placement in the light path decides how fine details in the original are broken up by the mask's shadow.

Title: Chain conveyor having synchronizing chain wheels and propulsion through the action of a claw
Inventor: PERSSON I
IPC: B65G23/28
Filed: 1988-11-09
Abstract: The invention relates to a conveyor for elongated objects such as logs and the like. Conveyors of this type have a plurality of parallel conveyor chains, which are synchronously driven by chain wheels mounted on a common axle. For the propulsion of the conveyor chains, such conveyors have hitherto been provided with a ratchet mechanism at the one end of the drive axle. According to the invention, the propulsion is instead effected by a device which acts directly upon one or more conveyor chains. This results, inter alia, in considerably lower torsion forces upon the drive axle, which can therefore be given more slender dimensions like bearings, etc. The force is transmitted from the chain or chains provided with propulsion members to the non-driven chains via the chain wheels and the common drive axle. <IMAGE>
