Abstract: 587,676. Cooling dynamo-electric machines. JACK & HEINTZ, Inc. May 3, 1944, No. 8372. Convention date, Dec. 23, 1942. [Class 35] An armature core and commutator are supported by fins carried by the shaft thus providing longitudinal cooling ducts and the core and commutator have tongues projecting between the fins. In the form shown a sleeve 20 has radially extending ribs 21 running the axial length of the armature core plus commutator these ribs engaging the inner periphery of the core laminae and of a sleeve carrying the commutator segments. The latter sleeve has fins extending inwards between the ribs and like the sleeve 20 may be of aluminium. The core laminae also have inwardly extending fins 26 having apertures 27 and external air is passed through these apertures and the gaps between the ribs and fans from one end of the armature to the other by a fan on the shaft or an external blower. The fins 26 on some of the core laminµ may be omitted so that the projections from the core are non-continuous as in Fig. 4.

In order to prevent the wipers contacting insulating material and to reduce the driving load due to flexing of the wipers in a switch having printed or like contacts, metallic areas electrically discontinuous from the contacts and flush therewith are printed or the like between the contacts. The metallic areas 12, Fig. 1, are joined by a printed arc 11 so that a wiper 13 having an oblique trailing edge connects the arc 11 individually to the contacts 10. The arc may be printed on the opposite surface of the insulating sheet 9 and be contacted by a second wiper connected electrically to the first. The insulated sheet may be slotted or indented between the metallic areas and the contact. As shown in Fig. 3, a double-ended wiper 21 is used, the printed arc 22 being diametrically opposite the metallic areas 19 and the contacts 16. Several levels of different diameters may be moulded together by heat and pressure to form a contact bank for use with a plurality of wipers.

Patent GB-768076-A (GB)
Title: Recovery of 3-chloronitrobenzene
IPC: C07C201/16
Filed: 1955-03-24
Abstract: 3-Chloronitrobenzene is obtained from mixtures comprising nitrobenzene and the 2-, 3-and 4-chloronitrobenzenes by sulphonating the mixture with oleum to preferentially sulphonate the nitrobenzene and the 2- and 4-chloronitrobenzenes and then separating the water-soluble sulphonated derivatives by treatment with water.  The above mixture is prepared by chlorination of nitrobenzene, and the residual unsulphonated 3-chloronitrobenzene is normally contaminated with dichloronitrobenzenes from which it is separated by fractional freezing at temperatures up to about 40 DEG  C., or by fractional distillation.  The sulphonation is effected using oleum of from 1-30 per cent or more strength (free SO3), in the temperature range of 40-120 DEG  C., preferably between 70 DEG  and 95 DEG  C., and the weight ratio of oleum to the mixture of chlorinated nitrobenzenes is between 0.5 : 1 and 10 : 1.  In examples: a crude mixture of chlorinated nitrobenzenes is added to 10 or 20 per cent oleum and after heating to 85 DEG  C. the mixture is diluted and washed with water, leaving 3-chloronitrobenzene as an oil which is purified by fractional distillation or freezing.  U.S.A. Specification 1,759,554 is referred to.

Title: Production of synthetic resin emulsion
Inventor: WARSON HENRY
IPC: C08F18/04
Filed: 1962-03-17
Abstract: Synthetic resin emulsions having a solids content of 35% or more by weight are prepared by polymerizing aqueous emulsions of vinyl esters of saturated aliphatic monocarboxylic acids in the presence of at least 0.5% by weight of a protective colloid derived from the thermal and/or acidic degradation of amylopectin and having a viscosity not exceeding 2000 centipoises in a 5% aqueous solution at 20 DEG  C. The vinyl ester may be vinyl acetate, and may be copolymerized with terminally unsaturated carboxylic acids and the esters thereof, e.g. acrylic, methacrylic, maleic, crotonic, fumaric and itaconic acids, esters such as 2-ethylhexyl acrylate and dichloroethylene. Polymerization may be effected in the presence of catalysts such as hydrogen peroxide, potassium and sodium persulphates or redox systems; emulsifiers such as nonionic polyethylene oxide surfactants, ammonium salts of sulphated esters and sodium salts of alkyl benzene sulphonic acids; and buffers such as sodium bicarbonate. Coatings obtained from the emulsions may be improved by the addition thereto of a gelling agent, e.g. potassium dichromate.  Examples describe the emulsion polymerization of (1 to 3) vinyl acetate and 2-ethyl-hexyl acrylate, (4) vinyl acetate and (5) vinyl acetate and crotonic acid in the presence of degradation products of waxy sorghum starch.

Title: Direct-current electric motors and control circuits therefor
IPC: H02P7/285
Filed: 1972-02-28
Abstract: 1403232 Motor control systems ASSOCIATED ELECTRICAL INDUSTRIES Ltd 26 Feb 1973 [28 Feb 1972] 9070/72 Heading H2J A D.C. motor, preferably either a shunt-field or permanent magnet type, is provided with a control circuit for cyclically applying pulses to the motor, the control circuit being such that each duty cycle comprises a pulse of a first polarity followed by a pulse of opposite polarity, the duty cycles being separated by periods of zero energization. In the preferred embodiment, steps are taken to eliminate speed fluctuations owing to varying friction over a revolution by setting the length T 1  of the accelerating pulse to the time required to accelerate from a first speed, e.g. zero, to a second speed W MAX , and setting the length T 2  of the decelerating pulse to the time required to decelerate the motor back to the first speed. As shown, for clockwise motor rotation, a direction selector 18 provides a "1" output to AND gates 26, 38 and 28 via inverter 30. A triggering pulse from variable oscillator 20 is stretched at 22 and causes AND gate 24 to provide a "1" output since a "1' output is present from a lower speed detector 16 having an input from motor speed sensor 12, since it is assumed at this moment the motor 10 is at rest. This causes a "1" output to be present at OR gate 44 which switches flip-flop 46 into its state with a=1. This, enabled via OR gates 36, 34 via AND gates 48, 50 causes supply circuit 52 to provide a first polarity pulse to the motor 10 and to accelerate it. This causes the output of detector 16 to become "0" and this, via inverter 32, causes "1" outputs to be provided by both gates 36, 34 to maintain the pulse. When W MAX  is reached, detector 14 changes to "1" and, via AND gate 38, causes OR gate 42 to change to "1" and this in turn causes flip-flop 46 to change to Q=1. AND gates 48, 50 are still enabled via gates 36, 34 and a reverse polarity pulse is applied to the motor 10. When the motor 10 reaches zero velocity once more the detector 16 provides "1" again causing gates 48 ,50 to be disabled since OR gates 34, 36 drop-out. The duty cycle is thus terminated and the circuits are at rest until the next triggering pulse.

Abstract: 107,587. Hubert, W., and Bosch, H. June 23, 1916, [Convention date]. Siphon discharge water-waste preventers; water-waste preventers discharged by displacers.-In a siphon flushing-apparatus for water closets &c., comprising a bell acting as a displacer and separate pulling devices for large and small flushes, the said pulling devices f, v extend through the flushing cistern a and through the middle of the bell d, act without lever mechanism, and are arranged coaxially. When the device f is pulled, the whole bell displaces water, which rises in the inner chamber, compressing the air therein, and flows down the flush pipe b siphonically. If, instead, the device v be pulled, the bell d is drawn down and an air valve i is opened, thus breaking the air-lock and allowing to flow down the pipe b only the water raised above its level by the displacement of the annular part of the bell d. A guide tube e is divided so that its two parts can be moved relatively to one another, whereby the amount of the flush can be varied. Fig. 4 shows a modification in which the air valve is dispensed with and the lesser flush obtained on pulling the device v by imiting the amount that the bell d can be pulled down, so limiting the extent to which the water will flow down the pipe b siphonically. A system of levers effecting this limitation of movement is described as an example.
