Patent GB-575684-A (GB)
Title: Improvements in or relating to voltage regulating circuits
IPC: G05F1/52
Filed: 1943-11-09
Abstract: 575,684. Automatic control systems for electricity supply. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. Nov. 9, 1943, No. 18605. Convention date, Feb. 3. [Class 38 (iv)] Voltage of a load circuit is maintained constant notwithstanding load or supply voltage changes or is given a characteristic rising or falling, with such changes by a series-connected thermionic valve V1, the grid voltage of which is controlled by an amplifying valve V2. According to the invention, the amplifier is a valve of lower voltage rating than that of the load circuit, namely a high mu low-voltage valve of the kind used in radio receivers, its cathode being connected to a partially stabilized positive voltage on a potential divider comprising, in addition to an impedance R7, a glow discharge valve V3 and an impedance R8 absorbing the voltage difference. The control grid 13 of the amplifier is connected to a potential divider R4, R5, R6, giving an adjustable voltage negative to the cathode. The amplifier is preferably a screen grid valve and the screen grid 14 is connected to a further potential divider comprising impedances R1, R2 and the elements V3, R8. By adjusting the voltage of the connection to grid 14, the characteristic of the control may be as desired. The arrangement permits of the stabilization factor being made infinite as in operation the voltages of control and screen grids change in phase. In a modification, the potential divider R4, R5, R6 is connected across the discharge device V3 and an additional impedance in series with R7 ; this arrangement avoids delay in obtaining a stabilized output voltage.

Title: Improvements in or relating to pest control and disinfecting agents
IPC: C07F3/10
Filed: 1955-06-28
Abstract: The invention comprises alkyl-mercury diacylimides of formula <FORM:0770267/IV(b)/1> where R1 is hydrogen or a straight or branchedchain C1-4 aliphatic residue, R2 is a straight or branched chain C1-5 aliphatic residue, R3 is an aromatic carboxylic or heterocyclic ring which may be unsubstituted or substituted with one or more halogen atoms or with one or more C1-3 alkyl radicals, and X is -SO2- or -CO-. R3 may be phenyl, naphthyl, pyridyl or quinolyl. The compounds may be prepared from the diacylimine, which may be prepared by reacting the pentachlorophenoxy fatty acid halide (e.g. chloride) with the aromatic acid amide at a temperature between 150 DEG  and 200 DEG  C., or by reacting the pentachlorophenoxy acetamide with the appropriate aromatic acid halide (e.g. chloride).  The diacylimine so prepared may be reacted with the dialkyl mercury compound, or alternatively the sodium derivative of the diacylimine may be reacted with the alkyl-mercury halide. The compounds may be used as fungicides (see Group VI).  In an example: (1) pentachlorophenoxyacetic acid chloride is reacted with p-chlorobenzenesulphonamide to give N-pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide, which in its turn is reacted with diethyl mercury in toluene to give N-ethylmercury-N-pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide.  Other examples describe the preparation of N-ethylmercury - N - pentachlorophenoxyacetyl - 3,4,6 - trichlorobenzenesulphonamide, N - isopropylmercury - N - pentachlorophenoxyacetyl - p - chlorobenzenesulphonamide and N - ethylmercury - N - pentachlorophenoxyacetyl - benzamide.ALSO:Fungicidal compositions comprise alkyl mercury diacylimides of formula <FORM:0770267/VI/1> where R1 is hydrogen or a straight or branched chain C2-4 aliphatic residue, R2 is a straight or branched chain C1-5 aliphatic residue, R3 is an aromatic carbocyclic or heterocyclic ring which may be unsubstituted or substituted with one or more halogen atoms or with one or more C1-3 alkyl radicals, and X is -SO2- or -CO.  R3 may be phenyl, naphthyl, pyridyl or quinolyl.  The compositions may be aqueous suspensions or dusting powders, and may contain kaolin, methylcellulose, sodium sulphate, sulphur and a wetting agent.  Specified compounds include N-ethyl-mercury-N-pentachlorophenoxy acetyl-p-chlorobenzene-sulphonamide, -benzamide and -3.4, 6-trichloro-benzenesulphonamide and N-isopropylmercury - N - pentachloro - phenoxy - acetyl - p - chlorobenzenesul - phonamide. In an example (5) a composition comprising kaolin, methyl cellulose, sodium sulphate, a wetting agent and the active compound is described.

Abstract: 422,685. Boiler gearing for mules. LEEMING, R. A., Dryclough House, Shaw Road, Royton, WALNE, W. S., 22, Radcliffe Road, Watersheddings, Oldham, both in Lancashire, BARNES, C. E., 33, 5th Avenue, Oozewood, HASTY, G., 36, Tandle Hill Road, and HOLMES, T., 64, Oldham Road, all in Royton, Lancashire. June 26, 1934, No. 18804. [Class 120 (ii)] In roller gearing for mules of the kind wherein, to produce uneven or slub yarns, the normal speed of the back roller 12, Fig. 2, is increased intermittently by means of an additional drive which comprises a rocker 3, Fig. 1, actuated by a rotary cam 2 and having catch or ratchet means 7, 8 which act in one direction to rotate the back roller, catch or ratchet mechanism 16, 17 being provided in the normal back roller drive and arranged to permit slip therein whilst the additional drive operates, the length of the periods of increased speed being adjustable, the rotary cam 2 is connected directly to the bottom front roller 18 and the rocker sector 3 is mounted loosely on a stud or shaft 4 which carries a ratchet wheel 7 and a gear wheel 6 rotating therewith and meshing directly with the back roller wheel 10, which is normally driven from the front roller pinion 1 by means of a spur wheel 13 loosely mounted on a shaft 14 and connected by catch or ratchet mechanism 16, 17 to a change wheel 15 meshing with the wheel 10. In operation the back roller 12 is normally driven from the front roller 18 through gear wheels 1, 13, pawls 17, ratchet-wheel 16, change pinion 15 and gear wheel 10, the gear wheel 6 and ratchet wheel 7 being rotated idly. This drive continues until the cam 2 oscillates the sector 3 whereupon the pawls 8 turn the ratchet wheel 7 and the gear wheel 6 which drives the back roller gear wheel 10 faster than previously, the pawls 17 now slipping on the ratchet wheel 16. The amount of roving fed by the back rollers is thus increased and a slub formed. As soon as the sector 3 ceases to be actuated by the cam 2 the drive through the gear wheel 6 ceases, and the normal drive is resumed. The throw of the sector 3 may be varied by setting a screw 19 to engage a stationary bracket 21 and thus vary the lower limit of the movement.
