Title: In-situ formation of soluble silicates from biogenetic silica in chemical fixation/solidification treatment of wastes
IPC: C04B18/30
Filed: 1988-07-28
Granted: 1992-09-16
Abstract: Disclosed is the solidification and chemical fixation of liquid wastes using biogenetic primarily amorphous silica to the waste in the presence of a strong alkali in the waste which converts the biogenetic silica into a soluble silicate, and in the presence of a polyvalent metal ion in the waste which reacts with the soluble silicate to provide a cementitious product of the waste. In the event there is insufficient strong alkali present in the waste to convert the biogenetic amorphous silica to a soluble silicate, and insufficient polyvalent metal ion in the waste to harden and form a cementitious product, amounts of these components as necessary can be added along with the biogenetic silica to the waste. The resulting cementitious and chemically fixed waste can be left in place, for example to provide a land farm, or can be removed and broken up and used as a cover for land fills, various land applications, and farms, as well as other applications.

Abstract: In order to enable the drawing-off of residual vapours of a low-boiling liquid from a pressure system (1) into a storage vessel (2), the pressure between said system and the storage vessel is first equalized, whereafter the presure in the storage vessel is reduced and the pressure in the pressure system increased, enabling thus passage of the low-boiling liquid with its vapours in the liquid state into the storage vessel. This process can be repeated in order to draw-off liquid with its vapours from the pressure system.

Abstract: 2.1 A simple operating procedure is intended to enable telephone connections to be divided up into categories and stored. With certain types of connection, the operator is to be obliged to enter an identification code derived from the content of the call so that it can be recorded and in each case summed up. 2.2 With a specific authorisation class allocated to a connection device, the release of the latter when a connection is cleared is not enabled until predetermined identification codes are sent from the terminal to the switching installation. Identification codes of this type are stored in a specific memory and in each case identical ones summed up. The contents of this memory are then available for statistical analysis. 2.3 Thanks to the memory and evaluation devices connected to it, it is a simple matter to establish how often calls in each case with the same content have been received. These may, for example, be complaints, fault reports or other operational information which may require the instigation of specific measures. <IMAGE>

Abstract: The present invention relates to the application of a synthetic hydrocarbon compound, a polyalphaolefin liquid, blended in various concentrations with chemical oil and water emulsifiers, thinners and oil and water surface tension reducers, the concentration of polyalphaolefin liquid to that of the remaining portion of the blend being no less than 5%; blending the polyalphaolefin liquid and the emulsifiers in a blending tank containing water base drilling mud; circulating the blend of polyalphaolefin liquid and emulsifier with the water base drilling mud down hole, so that the blend of polyalphaolefin liquid emulsifier and water base drilling mud lubricates the drill string or reduces the differential pressure between the wall of the borehole and the drill string so that the drill string is free to rotate and drilling may be undertaken with less drag or torque. In another application, the polyalphaolefin blended with the emulsifier serves as a spotting fluid in order to unstick drill pipe that has become stuck. In this method, the polyalphaolefin is blended with the emulsifiers; the polyalphaolefin emulsifier blend is introduced into the borehole as a "pill"; the pill is circulated downhole in the mud system through the annulus to the depth at which the pipe is stuck; the polyalphaolefin emulsifier blend acts on the differential forces between the wall mud cake and the pipe to reduce the differential pressure between the pipe and the formation, so that the pipe is freed and drilling is able to resume.

Abstract: In a process for the production of microcapsules by coacervation of gelatin, carboxymethyl cellulose (CMC) and a second anionic polymer such as a polyvinylmethylether/maleic anhydride copolymer or an ethylene/maleic anhydride/copolymer, the weight ratio of gelatin:CMC is chosen to be in the range 1:0.14 to 1:0.05, and the CMC used is chosen to have a viscosity in the range of from 50 to 140 mPas (cps), when measured in 6.0% by weight aqueous solution at 20 DEG C using a Brookfield RVT viscometer, Spindle No. 1, 10 r.p.m. The use of the specified weight ratio and CMC type permits significant increases in the solids content at which encapsulation can be carried out without increasing process viscosities to an unacceptable extent and/or giving rise to poor quality microcapsules. The process is particularly suitable for producing microcapsules for use in pressure-sensitive copying paper.

Abstract: When a screw fitting element (1) has to be screwed onto a very long bolt thread, this leads to a long assembly time because of the large number of turns. This time can be considerably reduced if the female thread (15) is bisected in the longitudinal direction and the two thread parts (9, 10) are connected to one another by means of a pivoting joint (5). The screw fitting element can be spread apart, pushed up close to the attachment point and then folded up. Subsequently, they must also be held together. This can be done with the aid of a bracket (4) or the like. The screw fitting element parts (7, 8) which exhibit or support the thread parts are connected by means of this bracket. In the effective position of the bracket (4), the thread parts (9, 10) form the female thread (15) which can be screwed on the bolt thread. <IMAGE>

Title: Radiant electric heaters
Inventor: SCOTT RICHARD CHARLES
IPC: H05B3/00
Filed: 1990-10-29
Granted: 1995-01-25
Abstract: A radiant electric heater (10) has two coiled resistance wire heating elements (22,24) each connected to one terminal (N) of a power supply via respective rectifiers. These rectifiers are each made up of two like-poled arms of a bridge rectifier (34) connected in parallel, and they are arranged to allow current through one heating element (22) on positive-going half-cycles of the power supply waveform, and through the other heating element (24) on negative-going half-cycles. The elements are rated for continuous power dissipation under these circumstances. A PTC thermistor (36) is connected between the ends of the heating elements connected to the rectifiers. Optionally an NTC thermistor (40) can be connected in series with the PTC thermistor. Upon initial energisation the PTC thermistor is a near short-circuit, so current flows through both heating elements on both polarity half-cycles, dissipating twice their rated power. The elements increase in temperature more quickly than if they were initially energised at only their rated power, so the visible response of the elements to energisation is faster. Meanwhile the PTC thermistor increases in resistance owing to self-heating, thereby removing the short-circuit after a few seconds, reducing the power dissipation in the elements to its normal level and protecting them from excessive operating temperatures.

Abstract: In known photographic processing apparatus, quality of the photographs produced can be adversely affected by drift in the paper processor of the apparatus. One cause of drift is incorrect replenishment of the chemicals used in the paper processor. In processing apparatus which utilise only small volumes of chemicals, drift can be caused by replenishment rates not matching the dye formed on the prints being processed, and an operator would need to take steps to adjust the processor. Described herein is an improved method of controlling the replenishment rate of chemicals in photographic processing apparatus. The method comprises deriving a control signal from the image to be exposed on to photographic material and using the derived signal to control the replenishment rate of the chemicals.

Abstract: In a lead accumulator, the recombination device normally mounted in an exposed position, for example on the lid or in the closure stopper, has been moved into the interior of the housing above the set of plates. It comprises a sequence of layers of hydrophobised mineral-fibre or active-carbon mats (2, 3) which are embedded in a metal sleeve (1) which is open at both sides and is preferably composed of lead, a central layer (2) being impregnated with catalyst material. The solid mechanical connection of the metal sleeve to a terminal bridge 5 effectively removes the heat of recombination from the catalyst layer and, in addition, prevents an electrostatic discharge which could result in an ignition of the gases formed by electrolysis. <IMAGE>
