Abstract: ABSTRACT OF THE DISCLOSURE A smoke detector receiving at two input terminals DC power from a remote source not only gives an alarm indication in response to a significant density of smoke at a local position, but senses the polarity of DC power at the terminals and generates a secondary signal, distinguishable from the alarm signal, when the polarity of power source is reversed.  The invention permits manual or automatic operation of a remote switch in response to a remote fire or other remote alarm condition to cause operation of the local alarm.  The remote alarm condition is distinguished early from the local alarm condition because the former is pulsed whereas the latter is continuous.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a process for the bio-technological preparation of poly-D-(-)-3-hydroxybutyric acid (PHB) which comprises continuously culturing a microorganism that is a strain of Alcaligenes latus or a PHB-producing mutant thereof, in two separate successive fermentation stages with unrestricted supply of nutrients.    The PHB-containing microorganism population cultured in the first stage with a dissolved oxygen content of 25 to 50% of the saturation value for air is then continuously transferred into a second fermentation stage in which the culture is continued at a dissolved oxygen content of 8 -15% of the saturation value for air.  The PHB is extracted in the usual manner from the biomass thereby obtained.

Pivot pins are loosely received in respective, preferably triangular, apertures for connecting the ears of the lid member with the casing to permit pivoting of the lid member and its bodily displacement relative to the casing in directions at right angles to the pivoting axis.  Thus, the lid member is movable, by a combination of the pivoting and bodily displacement thereof, between a closed position in which the plate portion is between the projecting edge portions at the straight side of the casing for closing the opening therein and an opened position in which the plate portion of the lid is disposed at the outside of the top or bottom wall of the casing adjacent the respective edge portion.  Coil springs are connected between the casing and lid member for pivotally urging the latter to a neutral pivoted position in which the plate portion is centered between the projecting edge portions and bodily urging the lid member, in its neutral pivoted position, toward the straight side of the peripheral wall of the casing.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of mending a defective wood plate uses, instead of putty, a solid patching material which is smaller in thicknesswise shear strength and compressive strength than the wood plate and is sized greater than a defect of the plate which is to be mended. The solid patching material is applied to the plate in such a manner as to cover the defect and, then, compressed in the thicknesswise direction to undergo shear fracture. As a result, that part of the material which overlies the defect is thrusted into the defect. The compression is effected in two consecutive stages, one using a rigid member and the other an elastic member. The part of the material filled in the defect is separated from the other part which remains on the plate. Where this method is applied to plywood production, the material will be forced into the defect without resorting to an extra compression step while the plate is being bonded to another.

Abstract: "MONITORING SURFACTANT CONTENT TO CONTROL      HOT WATER PROCESS FOR TAR SAND"             ABSTRACT OF THE DISCLOSURE       The present invention is based on the following:      (1) that when tar sand is conditioned and diluted in the hot water extraction process, there are two classes of anionic  surfactants (originating from carboxylate and sulfonate groups) present in the process water;      (2) that each of these surfactants has the potential to dominantly influence the maximizing of primary froth production by the process;      (3) that it is possible for a particular extraction circuit to determine the critical free surfactant concentration in the process water at which primary froth extraction is maximized for each of the two classes of surfactant;      (4) and that it is possible to determine which of the two classes of surfactant will first (that is, at lowest NaOH addition) dominate the process when a particular tar sand feed is being processed.      The present invention therefore involves:       - determining the critical free surfactant concentrations ("C?s" and "C?s") for the circuit for each of the carboxylate and sulfonate classes of surfactants;        - monitoring the free surfactant concentrations ("Ccs" and "Css") in the process water for an ore being processed;        - determining which of C?s and C?s occurs at a lower NaOH addition;        - and then adjusting NaOH addition to the extraction process to bring the first dominating surfactant concentration toward the critical concentration value.

Abstract: ABSTRACT "Solid Explosive Composition"     This invention provides a solid explosive composition comprising a low-water content melt-in-fuel emulsion when prepared at elevated temperature which solidifies on cooling. The emulsion comprises a continuous phase containing water-immiscible fuel and emulsifier and a discontinuous phase containing oxidizer salt.  A particulate material, preferably silica particles or a metal salt, effective as a nucleating agent is incorporated in the composition to reduce supercooling of the discontinuous phase and to accelerate crystallisation of the oxidiser salt.  The presence of the nucleating agent enhances the proportion of discrete droplets which remain totally encapsulated in the solidified composition and enables solid products to be obtained from relatively low melting oxidiser salt melts.
