Abstract: ABSTRACT OF THE DISCLOSURE:           This invention relates to herbicidal compositions of benzothiadiazinone dioxides and a urea derivative selected from the group consisting of N-3-chloro-4-isopropylphenyl-N'-methyl-N'-methoxy-urea, N-3-methyl-4-bromophenyl-N', N'-dimethylurea, N-[4-(4'-chlorophenoxy)-phenyl]-N',N'-dimethylurea, N-3-methyl-4-chlorophenyl-N',N'-dimethylurea and N-[4-(4'-methoxyphenoxy)-phenyl]-N',N'-dimethylurea. The compositions have a better action than their individual components while exhibiting the same good plant compatibility. These herbicidal compositions may be applied once or several times, before or after planting, before sowing, and before during or after emergence of the crop plants and unwanted plants. They are particularly suited to controlling monocotyledonous and dicotyledonous unwanted plants in crops.

Abstract: ABSTRACT OF THE DISCLOSURE      A process to remove contaminants from septic tank effluents by the conversion of the septic tank anaerobic treatment process to that of aerobic treatment.  The new process multiplies the effluent treatment effectiveness by passing the effluents through an exposed bed of adsorptive and oxidative coal particles.  In practice the effluents are intercepted as they are discharged from the tank and the treatment bed they are passed through is not more than 12 inches in depth.  This allows for a rapid turnover of oxygen through the bed between periods of effluent loading and unloading of the bed.  By maintaining an effluent level below that of the top of the coal particles all decomp-osition odours are removed.  Further treatment is provided as the treated effluent is discharged into an effluent dispersal field or into an interim sewage collection line by the use of the coal particles as permeable effluent distribution media.  Effluent from this treatment process is reported by Pollution Control Authorities to be better than Level "A" of the "Minimum Requirements for disposal of Municipal and Domestic Wastewaters to surface waters".

Inventor: CLARKE E COLIN W
IPC: C01B17/88
Filed: 1975-09-25
Granted: 1979-11-20
Abstract: ABSTRACT         An improved method is provided for concentrating aqueous sulfuric acid solution of concentration greater than about 75 weight per cent H2S04 by electrolysis in an electro-lytic cell wherein platinum electrodes are utilized without the build-up of sulfur deposits thereon.  To achieve this end, persulfate ions are provided in the solution and the electrodes are placed in sufficient proximity to one another and sufficient mixing is provided in the solution so that a substantial quantity of persulfate ions are conveyed into the region surrounding the cathode.  In an integrated system, drying of a wet fluid stream on a continuous basis is effected by contacting it with concentrated sulfuric acid and purify-ing and recycling the sulfuric acid by the method of this invention, only a small inventory of the sulfuric acid being required.

Abstract: LOCKING MEMBER FOR HAND-HELD TRIGGER ACTUATED SWITCH               ABSTRACT OF THE DISCLOSURE         A portable electric tool has an ON-OFF trigger operated switch and a locking member to hold the trigger with the switch in ON position.  The trigger has one end pivoted in the handle of the tool.  A portion of the trigger extends outwardly from an opening in the handle so that it can be manually moved inwardly to ON position by the operator while holding the tool by its handle.  Such inward movement is resiliently resisted and the ON position is momentary so that when the operator releases actuating pressure, the trigger automatically moves to switch OFF position.  The locking member to hold the trigger in switch ON position is pivoted in the handle of the tool centrally thereof and above the free swinging end of the trigger. The locking member is inherently biased to unlocked position. The locking member has an inwardly facing face which engages an outwardly facing face on the trigger, when the latter is in ON position.  The engagement is accomplished by the operator pushing in a protruding portion on the locking member while the trigger is held in ON position.  The pressure of the engagement between the two faces is sufficient to maintain the locking member in locked position.  Slight inward movement of the trigger will release such engagement and the locking member will automatically return to its unlocked position and the trigger will be free to be moved to and from ON and OFF positions.

Abstract: DETECTION - SYNCHRONIZER An asynchronous data input signal is detected and synchronized by a fast-acting circuit.  The input is used to modulate a local clock and a detecting latch is then driven by the data-modulated clock.  Most of the propagation delay found in conventional detector-synchronizers is eliminated since the SET input to the latch, which is essentially the clock signal, is generated without any gate delay and the CLEAR input is generated with only a single gate delay. Thus, the circuit is well suited for multiple clock systems in which detection and synchronization to one clock must be accomplished before the pulse of a second clock begins.

Abstract: DOUBLE DISC GATE VALVE WITH   REPLACEABLE SPACER RING     Abstract of the Disclosure A gate valve includes a pair of identically shaped tapered discs defining a tapered self-locking axially translatable gate wherein each disc has an annular hardened seating surface which engages the mating surfaces on the valve body adjacent the flow ports.  Tongues on the sides of the discs ride in vertical grooves on the valve body as the gate travels between a raised open and a lowered closed position.  The discs are separated by an annular spacer ring of substantially smaller diameter than the seating surfaces surrounding an interlocking segmented hub formed on the inner juxtaposed surfaces of the discs, the arrangement being such that the spacer ring can be sized to establish an overall gate width which will ensure that the seating surfaces are making proper sealing engagement with the valve seats with the diametral differences increasing the disc flexibility.  The spacer ring can be replaced by an appropriately sized spacer ring to compensate for thickness reduction in resurfacing the seating surfaces.  The discs of the gate are provided with a slot transverse to the flow ports which captures a T-head on the stem assembly, the slot being positioned in the gate interior radially within the seating contact area to thereby reduce the overall height of the valve.

Abstract: ABSTRACT OF THE DISCLOSURE Modification of the pore volume distribution of an alumina base catalyst support is accomplished by treating an alumina precursor of chi-rho-eta structure with an aqueous ammonium carbonate or bicarbonate solution under pressure at about 100-160°C for 10-24 hours, followed by drying and thermal activation at a temperature of at least about 500°C.  The resulting support will possess more than about 70% of its total pore volume in the 45-300 angstrom unit pore diameter range.  This pore volume distribution renders it particularly suitable for use as a catalyst carrier for hydrodesulphurization purposes.
