Abstract: Abstract A method for the production and purification of human tumor necrosis factor (hTNF) is described.  This purified material, shows growth inhibitory, hemorrhagic necrosis, cytotoxicity, and cytostasis effects on a variety of human tumors and cancers.  The hTNF is free of exogeneous endotoxin, bacteria, and serum factors. hTNF has a molecular weight of about 70,000  hTNF and human interferon used together have a far greater growth inhibitory or cytotoxic effect on human tumors than the sum of their separate effects.  The effect is synergistic and is seen with alpha-, beta- or gamma-IFN and with natural and recombinant IFN.

Abstract: ABSTRACT OF THE DISCLOSURE An optical display is provided to guide the operator of a metering device during the metering of a substance to a desired value.  The desired value is entered into a computer and the substance to be metered is applied to a balance.  The display is an analog display in the form of a clock face having a coarse and a fine indicator hand or hands.  During the coarse metering phase occurring at the start of the metering cycle, the coarse metering hand is rotated at a first rotational speed which is relative to the metering rate, i.e., the rate at which the substance is being applied to the balance.  During the fine metering phase, namely when the weight on the balance approaches the desired weight, either the same or another hand moves at a rotational speed which is relative to the metering rate but which exceeds the first rotational speed, thereby expanding the sector over which the hand moves while a given amount of the substance is being applied.  This greatly facilitates the operator's control over the process and decreases the possibilities that excess weight is added, since it provides an optimum, unequivocal indication to the operator of the actual weight on the scale during the metering process.

Abstract: TITLE CIRCUIT TO MINIMIZE LOCAL CLOCK FREQUENCY  DISTURBANCES WHEN PHASE LOCKING TO A      REFERENCE CLOCK CIRCUIT ABSTRACT OF THE DISCLOSURE           A frequency disturbance minimization circuit for use in a phase locked loop circuit.  A pulse gen-erator eliminates random phase shift, which occurs after a reference clock outage, by synchronizing counted down derivatives of the local and reference clock cir-cuits.  A window circuit provides a signal representa-tive of the difference in phase between these local and reference clock circuits.  A counter accumulates these phase difference window signals for periodic interroga-tion by a microprocessor which causes a voltage con-trolled oscillator to adjust its frequency in the direction necessary to eliminate this phase difference.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for recovering gold from refractory auriferous iron containing sulphidic material which comprises treating an aqueous slurry of the material in a pressure oxidation step at a temperature in the range of from about 135 to about 250°C under a total pressure of from about 500 to about 5000 kPa to oxidize sulphide sulphur to sulphate form and release gold from a refractory state.  The pH of the result-ant oxidized slurry is adjusted to a value suitable for cyani-dation.  The pH adjusted slurry is subjected to a cyanidation step in which gold is dissolved in a cyanide solution.  The cyanided slurry is diluted to a pulp density in the range of from about 2 to about 10% solids by weight.  The diluted slurry is subjected to a liquid-solids separation step to produce a gold containing solution and a relatively high pulp density gold-containing slurry, and gold from the gold-containing solution and from the high pulp density gold-containing slurry is separately recovered.

Abstract: PHOTOELECTRIC SMOKE DETECTOR          Abstract of the Invention A photoelectric smoke detector which operates on the scattered light principle and involves a light source, and a photosensor placed at an angle to the light beam such that it is normally not illuminated, the light source and photosensor being located within a dark detection chamber having air entry ports that restrict ambient light; smoke particles entering the smoke chamber produce interruption of the light beam, thereby scattering light beam, thereby scattering light onto the photosensor.  The detection chamber is formed within a cup-shaped grill which can be readily removed from the housing by rotation of the grill to disengage a locking mechanism; the grill is provided with an end wall and, integrally formed therewith, spaced inner and outer cylindrical side walls, the inner side wall being defined by baffles which include scoop fins that are used to trap light, but which also function to scoop air into the chamber and cause air turbulence for mixing the smoke particles thoroughly; the outer side wall having windows for entry of smoke.  The smoke detector may be tested by inserting a special probe into a hole located at the center and top of the grill, the probe interrupting the light beam and causing reflection of light onto the photo-sensor.
