Abstract: METHOD AND APPARATUS FOR UNDERGROUND DEPOSIT DETECTION         Abstract of the Disclosure A method and apparatus for collecting gas samples associated with underground minerals. A plurality of small gas sample containers are planted in an inverted position in shallow holes in the surface of the earth in a predetermined pattern, and upwardly migrating gases associated with the underground minerals being sought are collected in the containers for a predetermined time period, to obtain a time-integrated repre-sentation of the amount of one or more gases of interest migrating to the surface over that time period.  Two types of containers are alternately employed:  A total gas sample container in which all upwardly migrating gases are admitted into a sealed compartment at a preselected flow rate; and a specific gas sampler container in which strips of detector material which are sensitive to predetermined specific gaseous substances are mounted within the inverted container and exposed to the upwardly migrating gases over the predetermined time interval.  The containers are removed from the shallow holes after the lapse of the predetermined time interval, and the de-tector material alone, or the containers with the detector material still mounted, are sub-jected to qualitative and quantitative analysis. The gas collection period is maintained substan-tially constant for all containers.

Abstract: ABSTRACT      A method of and apparatus for separating from ruminant animal feces the undigested fibrous material that is preponder-antly short pieces which consist of bundles of capillary tubes. The feces are mixed with urine, water from animal washing and preparation for milking, and with other water if needed, to form a homogeneous slurry which is run through tandem perforated drum and roller squeezers that heavily compress the short pieces to express liquid from them while continuously draining off a filtrate of liquid and fine solids which is ultimately put into a pond for use as liquid fertilizer.  this leaves a filter mass which is preponderantly the short pieces.  The filter mass is mixed with clean water to form a suspension which is run through tandem perforate cylinder roller pressers that compress the short pieces under several times heavier pressure to produce a cleansed filter mass and a filtrate which is combined with the original slurry.  The cleansed filter mass is excellent bedding which is substantially odorless and effectively free of harmful bacteria.

Abstract: AN IMPROVED FAIL-SAFE ACTIVE BAND-PASS FILTER                ABSTRACT OF THE DISCLOSURE     This disclosure relates to an improved fail-safe elec-tronic filter circuit including a common-emitter transistor amplifier having a feedback path.  The feedback path includes an R-C twin-T network which is imperfectly nulled to only pro-vide regeneration at a preselected frequency.  An emitter-fol-lower circuit operates to isolate the series resistance branch of the R-C twin-T network from the collector of the transistor amplifier so that an output signal is only available during the presence of a signal having the preselected frequency and in the absence of a critical component or circuit failure.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method and an installation for the refrigeration by discontinuous charges of objects in bulk which occupy a long thermally-insulated zone, the method comprising essentially the steps of: carrying out the complete refrigeration of the objects located in a longitudinally-restricted portion of the thermally-insulated zone by circulating a main flow of cooling gas longitudinally inside the restricted portion, partly re-cycling the cooling gas outside the thermally-insulated zone to an injection station for frigorific energy such as refrigerated gas in the liquid or solid state, pre-cooling the objects located in a remaining portion of the insulated zone by the longitudinal circulation of an excess flow of non-re-cycled cooling gas through the remaining portion followed by evacuation to the atmosphere, circulating all the main flow of cooling gas longitudinally through the remaining portion of the insulated zone, and re-cycling an excess flow of said cooling gas outside said zone to the frigorific energy injection station with subsequent direct evacuation to the atmosphere.        The operations take place in two stages, the duration of the first stage being such that the cooling gas temperatures at the inlet and outlet of the restricted portion are substantially equal, the duration of the second stage being such that the cooling gas temperatures at the inlet and outlet of the remaining portion of the insulated zone are substantially the same.      Application to the cryogenic fragilization of objects for their grinding or separation.

The apparatus provides for regulation of the repetition frequency of current pulses, their amplitude and the level of the additional direct component, depending on the intensity of pain in the patient.  For this purpose an autoelectroanalgesia level remote control unit is provided, which is coupled to the intermittent analgesia unit, the unit for adjusting the amplitude of current pulses, which is additionally connected to a power unit, and to the power unit.          All this enables the patient herself,  depending on the intensity of pain, to select an individual level of anesthesia.  In this case, during acute pain, the intensity of pulse action is increas-ed by simultaneous step-up of the repetition frequency of pulses, their amplitude and the level of the additional direct component.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for analyzing trace components contained in a sample gas.  The sample gas is directed into a reaction chamber and ionized.  The resultant trace ions are drifted by an electric field, out of the sample gas, through an inert gas curtain and then through an orifice into a vacuum chamber where they are focused  and analyzed.  The curtain gas flow may be greater than the flow through the orifice, in which case the gas curtain acts as an ion window which is transparent to ions but blocks sample gas flow into the vacuum chamber.          Alternatively, the curtain gas flow may be controlled to admit a desired flow of sample gas through the curtain into the vacuum chamber, in which case the gas curtain acts as a window for ions and as an infinitely variable orifice for the sample gas.  Preferably the curtain gas is cryopumpable and is cryopumped by cooling the interior surface of the vaccum chamber.
