Abstract: ABSTRACT          A system for the sequential detonation of explosions.          There is a series of activating modules connected in parallel with a shot exploder.  The shot exploder supplies a series of calibrating signals.  The first calibrating signal calibrates the first module in the series and successive calibrating signals calibrate successive modules.  After each module has been calibrated it supplies a mode switching signal to the next module, so that the said next module responds to the next calibrating signal and is calibrated by it.  Each module has an internal oscillator (14), a calibrating counter (22), a timing counter (20) and a comparator (24).  The timing signals of the oscillator (14) are routed to the counters (20, 22) via gates (16, 18).  A mode control section (42) supplies a calibration mode signal to the gate (18) for the calibrating counter (22) and a timing mode signal to the gate (16) for the timing counter (20).  The mode control section (42) supplies the calibration mode signal when it receives a mode switching signal at an input terminal (40) and a calibrating signal from the shot exploder via a pulse discriminator (34).  The timing mode signal is supplied at the end of the calibrating signal.          A mode switching signal is then also supplied to the next module via an output terminal (50).  In the timing mode, the count of the timing counter (20) is compared with that of the calibrating counter (22) by a comparator (24).  When the counts are equal the comparator (24) resets the timing counter (20) and increases the count of a delay counter (26).  When the delay counter (26) has a count of 36 an activating signal is supplied to the detonator connected to that module via a terminal (28).

Abstract: ABSTRACT OF THE DISCLOSURE          An improved powdered bacterial growth medium composition adapted to be admixed with water is described.  The powdered growth medium includes an alkaline earth metal cation in a compound A admixed with a compound B containing an anion which reacts with the alkaline earth metal cation in compound A in an aqueous growth medium to form an essentially water insoluble salt or base, including the alkaline earth metal cation and the anion, which is acid neutralizing.  The water insoluble salt is thus formed in situ in the aqueous growth medium when compounds A and B are added to the aqueous solution.          Also described is an improved method for growing acid producing bacteria in an aqueous growth medium by forming the insoluble salt or base.  The resulting growth medium is particularly adapted for neutralizing acids generated during growth of lactic acid producing bacteria which are grown for use in various food fermentations.

Abstract: ABSTRACT OF THE DISCLOSURE            A flexible transmitting guide has a substantially transparent semi-solid core to which is shrink-fitted, or other-wise tightly clad, a transparent or translucent sleeve which is designed to laterally diffuse, disperse or refract a substantial component of light away from the core as it traverses the length of the guide.  Thus, the clad core appears bright along its length and functions as a primary light source. In modifications of the device, the lateral dispersion of light passing along the core is enhanced by interposing cuts or discontinuities at intervals along its surface, or by providing a sleeve comprising an emulsion of light-reflecting particles.  The light source may be adjacent to or separated from the core, and may comprise either a steady state, or pulsating source, ahead of which colored filters may be inserted, if desired.  Numerous indoor and outdoor applications are contemplated for light guides in accordance with the present invention, including for signs, safety vests for traffic policemen, lighted canes for the disabled, lights for instrument panels, safety lights for vehicles and ships, and lights for interior and exterior decoration.

Abstract: CONTINUOUS COATED SOLVENT RECOVERY PROCESS Abstract of the Disclosure A process for the recovery of solvent entrained in a water vapor laden exhaust gas stream exhausted from a spray painting system is disclosed. The process includes an oil absorption unit which absorbs and removes all but about 100 parts per million of the solvent from the exhaust gas stream while permitting air and water vapor to be vented from the system and a stripper which in turn removes all but about 0.001 mole fraction of any one solvent component trapped in the oil. The oil, which is substantially free of solvent, is returned to the absorption unit. The stripped solvent can then be condensed and reused by mixing it with the paint solids to be sprayed in the process; or, alternatively, it can be admitted as a vapor into the atmosphere surrounding a workpiece which is being coated in the spray painting system to raise the solvent humidity surrounding the workpiece to above about 70%. By raising the solvent humidity to above about 70% caking of paint on the interior surfaces of the spray booth, plugging of the paint spray nozzles, and rapid evaporation of solvent from the paint is reduced. The present process provides a means to recover and reuse even a complex mixture of solvents where the recovered solvent comprises a mixture of the same components in the same ratio as the solvent mixture originally used in the paint spray system. The system is described in relation to a continuous coater wherein parts to be coated move continuously through an enclosed paint spray area and are coated while the solvent laden atmosphere therein is exhausted from the coater for recovery of the solvent.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the production of a tungsten carbide-activated elec-trode, particularly an electrode which is utilizable as a cathode, and which consists of an electrically-conductive substrate with an active surface layer of tungsten carbide.  The tungsten carbide is adhesively bonded through chemical reaction to the surface of a substrate which is constituted of graphite or a graphite-like material.  With respect to a graphite-like material there is to be understood that this relates to a graphite binder mixture, whose binder material components, other than the graphitic filler granules, are only carbon-ized, but at least are not completely graphited.  The thus produced electrodes are particularly useful as the cathode in an electrolytic cell for the imple-mentation of the sulfuric acid-hybrid continuous cycle process, or as the cathode in an electrolytic cell for the anodic oxidation of SO2 waste gases at concurrent cathodic H2 formation.

Abstract: ABSTRACT OF THE DISCLOSURE An improved method of jacketing steel pipes which is particularly applicable for jacketing pipes of a diameter of between 50 mm and 500 mm is provided having high jacketing speeds and high throughputs. The pipe is heated initially to a temperature at least sufficient to cause a subsequently applied epoxy resin-curing agent powder blend to melt; a coherent and uniform epoxy coating is desired which may require subsequent heating of the epoxy coating. The epoxy coating will cure at a temperature from 145 degrees Centigrade to 155 degrees Centigrade within 50 to 70 minutes and the layer thickness should be between 30 and 50 micrometers. Prior to applying the jacket, the thermally produced reaction products must escape. This is ensured by an infrared radiation step which raises the temperature to about 200 degrees Centigrade. In the case of a thermo-sensitive interior of the steel pipe, this heating step provides not only for the evaporation of reaction products, but simul-taneously ensures that the preheated and slightly melted powder obtains sufficient fluidity.

Corder ABSTRACT      A programmable wall switch for controlling the time for turning on and for turning off an incandescent light includes a rectifying circuit for producing from the AC power line a selected DC voltage.  The switch includes a microprocessor powered by this DC voltage for turning on a light at any one of several selected times and for turning off the light at one of an additional corresponding several selected times.          A time display is provided for displaying the time as well as for allowing a user to review the programmed status of the switch at any one of several selected times.  A signal is generated at each zero crossing of the AC power line which is supplied to the microprocessor.  The microprocessor produces output signals which turn on, turn off or dim the light at selected times.  The ability of the microprocessor to dim the light further enhances the appearance of human occupancy when the switch is used to simulate occupancy of a vacant building.

Abstract: ABSTRACT    The spring compressor for large helical springs, more especially motor-vehicle axle springs, consists of two loose plate-like pressure plates (1, 2) with helically coiled ring surfaces (33, 34) as supports for the spring coils and each with a central through hole (21, 24) and of a threaded spindle (4) and a threaded tube (3). The threaded spindle (4) is concentrically and rotatably mounted by means of a thrust bearing in a guide tube (5) which, in the vicinity of the spindle head provided with a spanner profile (9), comprises a radially outwardly projecting bearing surface (12) with two elements securing against rotation (13, 14) for the pressure plate (2) at the spindle head end. The threaded tube (3), which is provided at its end with a nut thread which can be screwed on the threaded spindle (4), can be telescopically inserted into this guide tube (5). The threaded tube (3) and the guide tube (5) are connected together so as to be secured against rotation by two slot/key joints (17/15 and 18/16). The threaded tube (3) is connectable to the other pressure plate so as to be secured against rotation and in the axial direction of tension by two radial fingers (19, 20) at the end of the threaded tube so that the two pressure plates (1 and 2) cannot be rotated relative to each other when a compression spring is compressed.
