IPC: H01F1/03
Filed: 1953-07-07
Abstract: 734,243. Magnetic compositions. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 7, 1953 [July 10, 1952], No. 18796/53. Drawings to Specification. Class 38 (2). A ferromagnetic ferrite core having an initial permeability which is substantially constant over a range of temperature, comprises two or more layers of ferrite material having mutually differing initial permeability-temperature characteristics over that temperature range. Examples are described in which ring cores consist of two layers of equal or differing thicknesses of nickel zinc ferrites, the proportion of nickel to zinc varying between the layers. These layers may adhere by being moulded from superposed layers of powder, they may be clamped together, or stuck together with a non- magnetic binder, e.g. an ethoxylene resin. The results are illustrated by permeability-temperature curves. The layers may have different Curie points.

Title: Production of di-ammonium phosphate
IPC: C01B25/40
Filed: 1929-06-20
Abstract: 315,700. Federal Phosphorus Co., (Assignees of Klugh, B. G., and Seyfried, W. R.). July 16, 1928, [Convention date]. Ammonium phosphate. - In preparing di-ammonium phosphate in crystals of uniform size from concentrated phosphoric acid and gaseous ammonia, the heat generated by the neutralization is used to effect evaporation of water from the product. Phosphoric acid of 60-80 per cent strength is mixed with mother liquor from the process to reduce its viscositv and is treated in an insulated acid-proof tank Š with gaseous ammonia admitted through pipes 4. The liquid is agitated by a stirrer 3. Water vapour passes away through an outlet 6. After partial neutralization a further admixture with mother liquor is made, and the mixture is passed into a horizontal rotary cylindrical vessel B, from which air is removed either by a vacuum pump or by displacement by steam or ammonia. Ammonia is admitted through a pipe 15 in quantity sufficient to form di-ammonium phosphate. The solution which first becomes heated to about 100‹ C. is cooled and maintained at about 80‹ C. by water sprayed from a pipe 17. After admission of the ammonia is completed, the solution is allowed to cool slowly to atmospheric temperature, the vessel B being continuously rotated. The slurry is discharged into a filter or centrifuge. The crystals are dried at a temperature below 65‹ C.

Title: Improvements in or relating to the manufacture of hollow axially symmetrical bodies
IPC: B29C41/04
Filed: 1955-07-01
Abstract: Between the inner wall of a centrifugal mould and thermosetting resin being moulded therein is interposed a separating layer of a substance that is liquid at the temperature employed, has a higher specific gravity than the resin and is inert thereto.  The substance may be a simple salt solution, e.g. an aqueous ammonium nitrate solution, mercury, a fused salt, a molten low-melting metal alloy, e.g. Wood's metal, or a metal amalgam. Smooth-surfaced axially-symmetrical tubes are thus produced.  In an example the separating substance is mercury or lead hexanoate (s.g. 1,5), which is introduced into a spinning iron tubular mould in such amount as to form a layer 1 mm. thick, the resin is an epoxide resin (s.g. 1,2) and the temperature is 140 DEG C.  If heavy fillers are used, e.g. quartz, the separating substance must be heavier than the fillers.

Abstract: 1,262,216. Gas analysis. A. OPPEGAARD. April 22, 1970 [April 26, 1969], No.19180/70. Heading G1N. In the examination of gases and/or liquids, e.g. the effluent from a chromatograph, repetitive discharges are caused across electrodes in the chamber D by repetitively applying a rising D.C. voltage. Upon a change in gas constituent a change in frequency of the discharges occurs and a count of the number of discharges gives the quantity of constituent. In gas chromatograph measurements, the frequency of discharges is compared with a reference frequency, which may be obtained from a reference detector having only the carrier gas passed therethrough.

Abstract: 702,291. Washing and drying machines. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 18, 1952 [Aug. 18, 1951], No. 19504/51. Class 138 (2) In a washing machine comprising an agitator 15 or impeller mounted for angular movement in a tub 3 in a cabinet 1, the cabinet is adapted to house a food mixing machine 8, and means are provided for coupling the power unit of the mixing machine to the agitator or impeller. In the example shown, the tube 3 is of cylindrical form and the agitator 15 is oscillated through about 140 degrees by mechanism housed in a gear box 18 having a drive shaft 19 with one or more telescopic extensions 24. The mixing machine has a drive shaft 29 with a cross pin 30 adapted to engage in open-ended slots in the lower end of the extension 24. The effective length of the shaft 19 can be varied by means of a clamping screw 27 and slots (as 25) in the extension 24. In a modification the shaft 19 and extension 24 are replaced by a flexible shaft. The lower part of the cabinet 1 is divided by a partition 9 into two compartments, one receiving the mixing machine, and the other having shelves 12 for attachments for the mixer. The floor 7 of the cabinet is provided with locating depressions 32 adapted to receive rubber cr like feet 31 on the mixer 8. In Figs. 6. 7 (not shown) the locating depressions are formed in a shelf which is slidable into and out of the cabinet. A continuously or intermittently rotated impeller may be employed instead of an oscillating agitator. The agitator or impeller may be positioned in one of the side walls of a rectangular tub. In this case the tub may be mounted to one side of the cabinet so that the mixing machine can be housed in the cabinet to one side of the tub, with its driving shaft horizontal. The mixing machine may also be used to rotate the tub to spin dry the clothes. Specifications 663,502, 666,815, 670,353, 670,543, [all in Group II], and 678,400 are referred to. According to the Provisional Specification the agitator or impeller may be positioned in the bottom of a rectangular section tub so that its axis is equidistant from two opposite parallel walls of the tub, but unequally spaced from the other two parallel walls.

Title: Capacitor for conductive liquids
IPC: G01F23/26
Filed: 1957-06-21
Abstract: 820,245. Electric measuring systems. ENGINEERING RESEARCH CORPORATION Ltd. June 21, 1957 [June 26, 1956], No. 19604/57. Class 37. In a condenser of the type used for measuring the depth or volume of a conducting liquid in a container and having two electrodes which are surrounded by insulating material, at least one of the electrodes comprises a metallic coating at the interface of two closely fitting concentric tubular elements of insulating material. In one embodiment having electrode structures 102, 104, two main electrodes are formed by metallic coatings at the interfaces of insulating tubes 106, 108 and 144, 146. Inner structure 102 may comprise two separate spiral coatings, Fig. 3 (not shown), one of which acts as the electrode and the other as an electrostatic shield, exterior connections being made by ears 116, 114. The coatings may be profiled to match irregularities in the shape of the liquid container in which the condenser is housed. Structures 102, 104 are rigidly spaced and are sealed so that none of the liquid which enters the space therebetween can penetrate to the electrode surfaces. The condenser may further comprise a third electrode, formed by a series of vertical wires 128 supported by studs 126 on rings 122, 124, which is connected to ear 144 by a metal strap 140. In operation the wires 128 are maintained at earth potential and the capacity of the condenser is a maximum when the condenser is empty and decreases as the level of the liquid rises inside because the liquid forms a screen between the electrodes. The condenser 10, Fig. 1, with main electrodes 12, 14 and third electrode 16, may be included in a bridge circuit which is automatically balanced to indicate the liquid level. With condenser 10 empty, and slider 48 at the top of rebalancing potentiometer 44 (as viewed in Fig. 1), slider 62 of potentiometer 54 is adjusted to balance the bridge. With condenser 10 full of the liquid to be gauged and slider 48 at the bottom of potentiometer 44, the bridge is again balanced by means of potentiometer 38, thus fixing the empty and full limits for the liquid container. Intermediate indications of the liquid level may be obtained by applying the unbalanced output of the bridge at point 52 to an amplifier 66 and motor 68 which is coupled to drive slider 48 so that the bridge is again balanced.
