Patent GB-634436-A (GB)
Title: An improved method of producing frost-resisting concrete or mortar
IPC: C04B28/02
Filed: 1946-07-25
Abstract: A concrete or mortar having greater resistance to frost, and increased adhesion to iron reinforcements, and formed with less surface scum is prepared by adding to the mixture of hydraulic binding-agent, sand or gravel, and not more than 14 per cent of water, a plasticizing-agent and a gas-producing substance so that only pores of microscopic size are produced and the product contains not more than 8 per cent of air by volume.  The additions may be ground into the powdered binding-agent or may be added separately or together to the binding-agent or to the gauging-water.  The plasticizer acts also as a wetting-agent and so reduces the amount of water required, and may be a cyclic or aliphatic alcohol acid such as tartaric, citric, saccharic, dextronic, or salicylic acid, calcium lignin sulphonate, alizarin sulphonic acid, or humic acid, and may be present in amounts between 0.025 and 0.5 per cent of the binding-agent.  The gas-producing agent is soluble in alkaline liquids and is preferably also a surface tension reducing-agent either alone or as a result of reaction with the alkaline earth metals on the aluminium of the binding-agent and is present in amounts between 0.0005 and 0.5 per cent of the weight of the binding-agent, sufficient to produce a gas-content of 3-8 per cent by volume. Suitable agents are the alkali-soluble natural or artificial resins, e.g. pine resin insoluble in aromatic hydrocarbons, colophony and copal, or casein-, phenol-, or cresol-formaldehyde resins; or soluble sulphonates or sulphates forming alkaline-earth salts, e.g. lauryl alcohol sulphonate, fatty acid compounds of sulphonated hydroxyascetic acids, or fatty alcohol aulphonates of cetyl or oil acids; alternatively, metals which react with the solution of the alkaline earths of the binding-agent, e.g. calcium, magnesium, aluminium, or their alloys may be used.  Other substances for repelling water, regulating setting, and other purposes, e.g. alkali silicates and alkaline-earth chlorides or phosphates may also be included.  Tables are produced giving the results of the addition of tetrahydroxy adipic acid and pine-wood or cresol-formaldehyde resin; calcium lignin sulphonate, calcium chloride, and cresol-formaldehyde or naphthalene sulphonic acid-formaldehyde condensation product; the calcium salt of dextronic acid and sodium resinate, lauryl alcohol sulphonate or aluminium powder; and calcium lignin sulphonate, calcium chloride, and lauryl alcohol sulphonate.  Specification 405,508 is referred to.

Title: Process and apparatus for shaping and wrapping soft masses of material
IPC: B65B25/06
Filed: 1933-08-08
Abstract: 408,852. Moulding and wrapping plastic substances. HILGERS, W., 246, Minister - strasse, Dusseldorf, Germany. Aug. 8, 1933, No. 22175. Convention date, Aug. 6, 1932. [Class 94 (i).] Plastic substances such as lard, butter, cheese, &c. are shaped and fed into a wrapping machine by a portion, for instance the base, of the shaping chamber. The material is fed from a trough 1, Fig. 2, by a worm 3 into a shaping chamber. The base of the chamber is formed by a plunger 9, the top by a slide 13 and the back by a wall perforated at 41 to allow the escape of air. When the chamber is filled, a slide 5 rises to separate the shaped portion, the slide 13 is withdrawn, and the plunger rises to the position shown to transfer the shaped block into a pocket 20 on a rotary turret 19. In its ascent, the block carries up a wrapper 23 which has been fed on to a grid 22, and the sides of the pocket cause the wrapper to be disposed about three sides of the block. The pocket has been moved bodily to the right, Fig. 2, into the receiving position by a control arm 25, a stop 36 causing the left hand side to open slightly to widen the pocket during the insertion of the block. The control arm moves to the left, and springs 26 carry the pocket in the same direction. During this movement, a stationary folder 27 turns up the depending flap 28 of the wrapper. A blade 32 on a swinging arm 29 turns up the flap 33. The turret makes a rotational step and the wrapping is completed in any suitable manner at stations c, d, e. In a modified construction of shaping chamber, Fig. 6, the back is formed by a plunger 41 which moves into the position shown, air being expelled through vents 44, and recedes as the shaping takes place, exerting suction on the plastic mass. The chamber may be disposed at right angles to the position shown. Apparatus for spraying the chamber with liquid between the shaping operations may be arranged to operate in timed relation therewith.

Abstract: 506,053. Fluid-pressure servomotorcontrol systems. DICKSON, W. S. Aug. 13, 1937, No. 22299. Void. Convention date, Aug. 14, 1936. [Class 135] A regulating - apparatus for varying the pressure of an operating fluid in response to changes in a condition to be controlled comprises a lever 25 fulcrumed at 26 and loaded by a spring 35 which is acted upon by the variable condition, in this case the pressure in a conduit 58 which acts on a bellows 14, to control the escape of the operating fluid from a nozzle 5 of a supply conduit 11 having a restricting plug 11<1>. A variable pressure is thus obtained in a conduit 12 which is utilized to effect an adjustment of the controlled condition, such as an adjustment of a regulating valve 59 in the conduit 58 by means of a diaphragm motor (not shown). Either of two bellows 13 and 14 may be used for receiving the regulating impulse, the other being used as a compensating device to avoid "hunting" effects, and restricting plugs 17 and 18 may be provided in the conduits leading to these bellows. The fulcrum point 26 of the lever 25 is adjustable by means of a screwed rod 28 and the tension of the loading spring 35 is also adjustable by a screw 38. A leaf spring 43 is secured to the end of lever 25 for co-operating with the nozzle 5 and also actuates a cleaner rod 6 arranged within the nozzle against a spring 9. As well as pressure, the regulator may be used for regulating vacuum, rate of flow of steam, air or other fluids, temperature, speed, liquid level, density of liquids, humidity, feed lines, voltage, &c.

Abstract: 774,308. Circuits of radiation-sensitive devices. WESTERN ELECTRIC CO., Inc. Aug. 6, 1954 [Aug. 10, 1953], No. 22924/54. Class 40 (3). An alternating currentgating circuit comprises input terminals shunted by an impedance R1, output terminals shunted by an impedance R2, and light-responsive semi-conductive device 21 connected between the input and output terminals. The alternating signal being gated is applied to the input terminals, and a load to receive the gated signal is connected across the output terminals. The semi-conductive element is a P-N junction and a biasing source 22 is connected between the other input and output terminals. An optical system utilizing for example the sun, directs light on to device 21. When the photo-cell is dark its resistance is high and only a small part of the A.C. signal is transferred to the load. When the cell is illuminated the gate is opened. In the arrangement of Fig. 3 (not shown), the P-N junction is replaced by an N-P-N or P-N-P junction as also is resistor 42. Biasing battery 22 may then be omitted. A change-over switch illuminates by means of electric light either of the semi-conductors. Thus when one is conductive the resistance of the other is high and vice versa. Resistor 20 may also be replaced by a light-sensitive semi-conductor illuminated at the same time as that replacing resistor 19. In the arrangement of Fig. 4 (not shown), a card translator for telephonic equipment comprises a number of apertured cards so arranged that if a particular row of apertures is aligned light passes through them, thus opening a gate of the type described above.
