Title: Improvements in electromagnetic devices
IPC: H04R1/22
Filed: 1924-09-01
Abstract: 243,787. Western Electric Co., Ltd., (Western Electric Co., Inc.). Sept. 1, 1924. Magnetic instruments ; diaphragms.-A loudspeaker, or a telephone transmitter, is constructed to simulate an electric transmission line having a constant impedance to all frequencies over a wide range. The magnetic portion 17 of an armature 14 lies at the intersection of orisscross pole pieces 10 - - 13 of a U-shaped permanent magnet 15, the coils 16 being disposed as shown in Fig. 5. The armature is connected to a diaphragm 40 by means of a rod 33 and spiders 42, 45 disposed on opposite sides of the, diaphragm. The whole instrument is considered as analogous to the transmission line shown in Fig. 8, the inductances 74, 76, 77, and 78 being the inductance of the winding 16, the mass of the -armature 17, the combined masses of the spiders 42 and 45, and the effective mass of the diaphragm 40 respectively. A condenser 85 is connected across the winding 16, the capacities 79, 80 and 81 representing the inverse of the elasticities of the part of the armature coupled to the diaphragm, the combined elasticities of the spiders 42 and 45, and the air in block 75 represents the coupling between the electrical and mechanical portions of the instrument. The transformer 83 represents the coupling between the diaphragm mass and the air column in the horn, which has a constant mechanical impedance represented by resistance 82. A mathematical analysis is given, the values of the masses and elasticities for a constant impedance up to 6000 being deduced. The armature 14 is made of light material such as aluminium and is cut away to leave only two strips 18, 19 and a tongue 20, Fig 3. The strips 18 and 19 are turned up at their outer edges for stiffening purposes. The tongue 20 is bent to form a knife edge at one side and a groove on the other for attachment of the rod 33, Fig. 1, by means of a washer 35 having a groove to receive the knife edge. The armature is supported between curved surfaces 21, 22, 23 and 24, Fig. 2, on members 25, 28 which are pressed against the armature by screws 29. The contacting points of surfaces 21 - - 24 are in the same plane with the armature in its middle position. A modified mounting for the armature is between points 58, 59, Fig. 7, and a curved surface 60. Each of these mountings provides a restoring force which increases with the deflection of the armature in the same manner as the magnetic field, being only sufficiently in excess to prevent freezing to the pole pieces. Any difference acts as a series capacity in the line shown in Fig. 8 and tends to make the impedance of the network variable with frequency. The spiders 42, 45, Fig. 1, are held against ridges on opposite sides of the diaphragm and attached to the rod 33 by a bushing 41 and nuts 44, 47.

Filed: 1927-08-08
Abstract: 275,662. I. G. Farbenindustrie Akt.- Ges. Aug. 7, 1926, [Convention date]. Hydrogenation, destructive.-In the production of hydrocarbons of low boiling point by the destructive hydrogenation of carbonaceous materials by heating the materials under high pressure in presence of hydrogen but in the absence of carbon monoxide, deposition of carbon on the walls of the apparatus is avoided as described in Specifications 268,796 and 271,451 by lining not only the walls of the reaction vessel but also the other parts of the apparatus which come into contact with the hot reacting substances with materials not giving rise to the deposition of carbon or the formation of methane. Alloys containing cobalt, molybdenum, tungsten, vanadium, and manganese are suitable and these alloys may also contain nickel, boron, arsenic, antimony, silicon, bismuth, phosphorus, or selenium alloyed therewith or in co-operation on the surface thereof. If the reacting materials are freed from sulphur, copper also may be used. Alloys in which the boundaries between the crystal grains are free from impurities, as determinable by microscopic examination, are especially suitable. The alloys have also catalytic action on the reacting materials. Specifications 272,556 and 273,712 also are referred to.
Patent GB-629711-A (GB)
Title: Distillation of acid-treated mineral oils
IPC: C10G7/00
Filed: 1947-08-01
Abstract: <PICT:0629711/III/1> The distillation of an acid-treated mineral oil is effected with little corrosion or fouling of the distillation equipment by substantially, but not completely, neutralizing the esters in the oil with caustic alkali, and completing the neutralization with an oil-soluble material such as a naphthenic acid soap, an amine, an alkali phenate, a tetra-alkyl ammonium hydroxide, a tetra-alkynol ammonium hydroxide, or a fatty acid soap; the distillation is then carried out in the presence of the added materials.  It is also advantageous to add a small amount of a mineral oil heavier than that being distilled.  Acid-treated oil from tank 1, and caustic containing the oil-soluble "promotor" from tank 2, are pumped through meters 5 and 6 to plate-tower 8 which is heated by closed-steam coil 9 and evacuated via condenser 14 and line 15. In an example, an acid-treated catalytic naphtha was 95 per cent neutralized with caustic soda, and 2 per cent by volume of crude sodium naphthenate was then added: the neutralized naphtha gave a satisfactory result in a fouling test.

Title: Improvements in or relating to tap locking devices
IPC: F16K35/02
Filed: 1943-12-16
Abstract: 585,811. Pipe joints. COOPE, J. T. L. Dec. 16, 1943, Nos. 21139/43 and 23463/44. [Class 99 (i)] [Also in Group XXIX] A pipe is prevented from becoming disconnected from a gas or like tap by an operating member which serves to disengage a spring- actuated locking device from the tap valve when in its operative position. The operating member is held in its operative position by engaging a part of the tap valve when the latter is in the open position. As shown in Figs. 1 and 2, the locking device comprises a U- shaped member 6 urged by a spring 7. to engage flats 5 on the tap valve or plug 4 when the latter is in the closed position. The member 6 is slidable in a guideway 2 in the tap body 1 and can be moved out of engagement with the plug 4 by an operating member 8 also slidable in the guideway 2 and having a bifurcated part 9 which freely embraces the plug 4 without restraining its rotation. The member 8 may be loosely mounted on a flexible or other pipe 11 connected to the outlet 3 or on a rubber or like resilient union 10. When the member 8 is in its operative position and the tap is open as shown in Fig. 2, the member 8 cannot be withdrawn and hence the pipe 11 uncoupled until the tap is: again closed. The member 8 may have resilient arms to facilitate clipping to the pipe or union. Fig. 5 shows a modification in which the locking device comprises a pivoted pawl 16 moved into engagement with a coacting part 17 of the tap plug 4 by a spring 19 and held out of engagement with the plug 4 by an operating member 18 shaped at 20 to allow the plug 4 to rotate freely, In a further modification, the pawl itself is constituted as a double flat spring. In all cases, the spring of the locking device may be sufficiently strong to throw the operating member clear of the tap body when the tap is turned to its closed position. According to the first Provisional Specification, the operating member may form the means for clipping the union to the flexible or other pipe. According to the second Provisional Specification, the operating member may be formed as a flat bar with a hole for the free rotation of the tap valve and a slot leading off rearwardly from the hole to form a locking recess.

Abstract: 1,077,300. Television. GENERAL PRECISION SYSTEMS Ltd. April 27, 1966 [May 19, 1965], No. 21261/65. Heading H4F. [Also in Division B7] The invention relates to visual simulation apparatus in which a scale model of terrain, specifically an airport and its approaches, is viewed by a relatively moving camera of a closed-circuit television system, the model including a plurality of lamps L disposed along the approach to the airport runway which are briefly energized in cyclic succession under the control of a counter C and a diode switch E for the purpose of simulating " strobe " approach lighting. In accordance with the invention the cyclic energization of the lamps is synchronized with the operation of the television system by driving the counter C from a multivibrator B which is synchronized by the television field or frame pulses applied at A. The lamps are " over-run " so as to flash brightly when momentarily energized. Multivibrator B continues to run freely in the event of interruption of the television synchronization and thereby prevents a lamp from burning out due to continuous energization. The model is mounted on a moving band, and counter C and switching unit E are constructed of subminiature components so that they may be mounted in the model, hidden in suitable features, so as to reduce the number of electrical connections which must be made to the model via slip rings.
