Title: Improvements in or relating to means for the automatic and other electric control of variables
IPC: G05D3/10
Filed: 1941-12-24
Abstract: 552,823. Automatic control systems and apparatus for electricity supply. CROMPTON PARKINSON, Ltd., CASS, V. S., and BURGE, H. O. Dec. 24, 1941, No. 16634. [Class 38 (iv)] A resistance control device comprises a narrow annular chamber having an outer wall 1 of insulating material in communication with a reservoir conducting liquid and contact studs 2 extending through the wall of the chamber adapted for connection to resistances or resistance tappings, the studs being at different horizontal levels and successively out of alignment vertically, adjustable means altering the volume of liquid in the reservoir to alter the level of liquid in the chamber. The adjustable means may be a plunger piston or diaphragm and may be operated directly or indirectly by an electro'- magnetic device such as a solenoid, electromagnet or torque motor. The lowermost and uppermost contacts may be connected only to indicating means for testing purposes. A plunger 3 constituting with the insulating wall the annular chamber may be raised against a spring 10 by a coaxially arranged solenoid 6 the position of which is capable of vertical adjustment. Such a device may be connected to tappings on a resistance 20 for example in the field circuit of an alternator, the solenoid 6 being connected in series with a manually adjusted resistance 29 and a fixed resistance 28 across the output terminals 25, 26 of the alternator. Contacts engaged by a manually adjustable contact arm 30 may be connected in parallel with the contacts of the resistance 20 controlled by the plunger. A switch 27 in series with the solenoid is adapted to be opened when the plunger is lifted manually to its highest position.

Abstract: 812,275. Impregnating concrete. MAATSCHAPPIJ TOT HET UITVOEREN VAN ASFALTWERKEN N.V. June 10, 1955 [June 11, 1954; Aug. 19, 1954], No. 16816/55. Class 140. A method of manufacturing concrete building or constructional material is characterized by penetrating with a " tough material " a concrete material having an aggregate of a uniform grain size and a high degree of porosity with the pores in the main intercommunicating. A mineral aggregate in which the smaller grains cannot fit in the interstices of its longer ones is defined as an aggregate of uniform grain size. The stretch of diameters of the grains which form the mineral aggregate is termed the proportionality stretch which may extend to 1 : 0.3. A relatively small quantity of cement is used. Tough material is defined as one which has an ability to flow at normal temperatures, has a low elasticity module and preferably a low melting point, is preferably soft and is such that if two surfaces of the material are pressed together they will unite to form one body of material which will withstand rapidly changing stresses and strains below the elastic limit of the material. Specified tough materials are asphalt and pitch. Penetration of the tough material into the concrete can be accomplished by applying the tough material in a liquid state at high temperature, as a solution or as an emulsion; vacuum-pressure impregnation technique may be used. Fig. 1 shows a section of a pile on a base, wherein the upper layer 1 of the pile has been penetrated with asphalt, whereas the lower layer 2 has not been penetrated.

Title: Improvements in or relating to speed-controlling means for direct current electric motors
IPC: H02P7/06
Filed: 1943-10-14
Abstract: 570,895. Automatic control systems for electric motors. SCOTT, W. Oct. 14, 1943, Nos. 16903 and 19997. [Class 38 (iv)] Speed.-Relates to speed controlling means for a D.C. motor wherein one of a pair of contacts adapted to short-circuit resistance in the field circuit is carried by a spring which is manually flexed to separate the contacts, but allowed to straighten by speed responsive means to effect their engagement. Cyclical variation of speed is prevented by means biassing the contacts towards engagement which is, upon engagement, reduced in effect. As shown, the fixed contact is a carbon annulus 7 on a steel spindle 18 which is adjustable in respect of the movable contact 8 by a knob 16 screwed upon the cover 17 of an open-sided, stationary cylinder 2, and secured in adjusted positions by a spring-controlled pin 24 engaging a ring of apertures in a disc 25. The moving contact is carried by a spring 9 flexed by the arms 10a of a spring 10 driven by the motor shaft 1 and connected by a slip ring 4 to brushes 5. The arms 10a are stressed by a tension spring 11 and weights 14 are held in position on tension-adjusting screws 12 by springs 15. The spring 9 and/or contact 8 are of magnetic material and a coil 28 surrounds the spindle 18. This coil is connected in series with the field winding and a resistance, a portion of which, together with the coil, is short-circuited when the contacts engage. Alternatively, it may be connected in series with the armature. In the first case, it becomes ineffective, and in the second is reduced in effect, when the contacts engage, and rapid vibration of the moving contact results.

Filed: 1950-07-11
Abstract: In preparing undenatured gluten, wet gluten-containing material, e.g. crude wheat gluten, starch-free wheat gluten, pure wheat gluten or fat-free wheat gluten, is mixed with 0.005 to 0.015N volatile acid, e.g. hydrochloric, lactic or acetic acid and agitated to form a dispersion containing between 5 and 15 per cent. of gluten and having a pH between 5.0 and 5.8 and preferably a normality of 0.005 when the gluten concentration is 5 per cent. and a normality of 0.015 when the gluten concentration exceeds 10 per cent.  Dry powdered undenatured gluten, suitable for improving the baking quality of flour, may be obtained by spraying the dispersion into a vessel having an inlet and outlet, with air having an inlet temperature of 120-150 DEG C. and an outlet temperature of 65 to 120 DEG C. or by freeze-drying it Solid impurities may be removed from the dispersion and undenatured gluten may then be precipitated by agitating it and adjusting its pH to between 6.0 and 8.0, preferably 6.4 to 6.8, e.g. by adding calcium hydroxide solution.  Alternatively the undenatured gluten may be salted-out of the dispersion.  The precipitate may be separated from the liquid and dried.  The precipitate may be redispersed in 0.005 to 0.015 N volatile acid to give a colloidal solution containing less than 15 per cent. of purified undenatured gluten which may be obtained as a dry powder by spray-drying the solution as described above.ALSO:Dry powered undernatured gluten, in the preparation of which wet gluten-con-taining material is dispersed in 0.005 to 0.015 N volatile acid (see Group V), is added to flour to improve the crumb colour and texture and increase the volume of bread produced therefrom.

The residues used are those obtained by destructive hydrogenation or heat-pressure treatment of coal, peat, shale, tars or mineral oils, and they are preferably heated to 250‹ to 300‹ C. to remove lighter fractions. The residues may be deposited on the diaphragm from suspension in the liquid to be treated or in another liquid, or if they take. the form of a paste or pulp they may be applied directly to the diaphragm. The Figure shows an arrangement in which a rotary vacuum filter A receives, in the space B, a layer of carbonaceous residue supplied from a container G.
