Abstract: 668,384. Electric analogue calculating systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 19, 1950 [Jan. 28, 1949], No. 2458/49. Class 37. In apparatus for electrically solving multiterm simultaneous equations, corresponding terms of the several equations are represented by series circuits comprising variable impedances, one for each equation, whose magnitudes are analogous to the coefficients and which carry variable alternating currents analogous to the unknowns. Switching means successively and sequentially select and connect in series in appropriate senses the impedances corresponding to the several terms of each equation, and the resultant error voltages across the selected circuits are separately and successively displayed on a C.R.O., whereby each error voltage is reduced to zero by successive adjustments of the variable currents, whose values then represent the several unknowns. Fig. 2 shows an arrangement for solving the equations in which the unknowns are represented by four variable alternating currents 11 to 14 flowing in series through four circuits containing resistances r11 to r41, r12 to r42, r13 to r43, r14 to r44, representing the coefficients. Sequentially operated selector switches P1 to P4 connect in series the appropriate sensed voltages representing the terms of each equation to produce successive error voltages, which are combined (Fig. 3) with preset biasing voltages analogous to terms V1 to V4 derived from A.C. energized potentiometers such as BR1 and applied through a logarithmic variable gain amplifier LA to the Y-plates of a long persistence C.R.O., whose traces are displayed adjacently by the successive application of preset direct biasing voltages from the rectifier-fed resistor TR1. The variable alternating currents II to 14 are successively adjusted to reduce each vertical trace to zero, beginning with the longest, and the currents then represent the solution values of the equations.

Title: Horticultural pest control agents
IPC: A01N63/30
Filed: 1956-01-27
Abstract: A manure capable of controlling ellworm infestation in soil comprises animal manure treated with propagules of a predacious fungus of the class moniliaceal obtained by the aerobic and preferably the submerged aerobic fermentation of the fungus in a culture medium (see Group VI).  The treatment is carried out by building the heap of manure in layers and spreading the mycelium separated from the culture on top of each layer as it is formed. After standing e.g. three months, the treatment is repeated and after further standing the manure is ready for use.  Single or mixed species of fungus may be employed especially a mixture of a slow and rapid growing species e.g. Dactylaria thaumasia and Dactylaria doedycoides.  Other species specified are Dactylaria candida (Nees) Sacc., Dactylela doedycoides Dreschles, Dactylella ellipsospora (Preuss) Grove, Arthrobotays canoides Dreschler, Trichothecium flagraas Duddington, and Arthrobotrys robusta Duddington.ALSO:A composition for incorporation in soil for the control of eelworm infestation comprises propagules of a predacious fungus of the class Moniliaceae in admixture with a solid organic carrier material decomposable in the soil, e.g. animal manure, shoddy, textile waste, bran and leaf mould.  The fungi may be employed as a single species or mixed species.  Specified are Dactylaria thaumasia Dreschler, Dactylaria candida (Nees) Sace, Dactylella doedycoides Dreschler, Dactylella ellipsospora (Preuss) Grove, Arthrobatrys conoides Dreschler, Trichothecium flagrans Duddington and Arthrobotyrs robusta Duddington.  Preferably a mixture of a slow and rapidly growing fungus, e.g. Dactylaria thaumasia and Dactylaria doedycoides is employed.  The propagules are prepared by growing the fungus in a culture medium containing available sources of carbon, hydrogen and nitrogen under aerobic and preferably submerged aerobic conditions.  The temperature is 15 DEG  to 37 DEG C. and preferably 24 DEG  to 28 DEG  C. and the duration is 4 to 10 days, preferably 7 to 8 days.  A preferred medium contains a carbohydrate, one or more amino acids, corn steep liquor and water, especially glucose, peptone, glycine, sodium chloride, corn steep liquor, maize meal and water.  The aqueous medium is inoculated with spores of the fungus produced on a solid medium, e.g. agar containing maize extract and glucose.  After fermentation, the mycelium is separated from the broth and may be dehydrated.  The moist or dry mycelium is incorporated in the carrier which preferably supports the growth of the fungus.  In the case of animal manure, mycelium is added to the manure which is then allowed to stand up to several weeks before being incorporated in the soil.

Title: Carburettors for internal-combustion engines
IPC: F02M1/02
Filed: 1932-02-03
Abstract: 388,193. Spray carburetters. DODSON, E., 66, Lewin Road, Streatham, London. Feb. 3, 1932, No. 3205. [Class 7 (iii).] An automatic inlet relief valve is associated with a manually-actuated air strangler, the control means for the relief valve being such that the resistance to opening does not increase substantially once the relief valve has materially opened ; means are also provided to adjust the throttle in accordance with the strangler actuation. The strangler, Fig. 1, consists of a disc 5 mounted on a spindle 8 and having a hinged portion 6 serving as the automatic relief valve. This is loaded by a spring 7 which, after the portion 6 has opened materially, bends over the spindle 8. To ensure that when the strangler is closed, the throttle 3 will be in the correct position for idling, an arm 9, Fig. 2, is connected to a crank 14 on the strangler spindle and serves as a stop to be engaged by a lug 11 on the throttle lever 12. In a modification, Fig. 7, the strangler disc 5 is pivoted eccentrically on the spindle 8 and is loaded by a spring 7 attached to a crank 21 on spindle 8 and to a stud 23 on a .strangler-actuating plate 22. When the strangler is open the axis of spring 7 passes practically through the centre of spindle 8. When the strangler valve is brought to the closed position, a rod 26 is moved to bring a stop 29 to a position to limit the movement of an arm 30 on the throttle valve spindle. In a further modification, a downdraught carburetter is described in which a stud on the strangler-actuating disc engages a curved end of a lever the other end of which, with lost motion, is adapted to engage a stud on a crank attached to the strangler spindle. Fuel that is unvaporized collects in a depression 15, Fig. 1, and is atomized by air entering through an aperture 16.
