Title: Improvements in process for dewaxing hydrocarbon oils
IPC: C10G73/06
Filed: 1935-05-18
Abstract: <PICT:0450367/III/1> Mineral oils and distillates containing wax and asphalt are dewaxed by adding with liquefied normally gaseous hydrocarbons and then chilling the resulting solution at a high rate exceeding 400 DEG  F. per hour whereby asphalt particles are precipitated which form nuclei upon which the wax forms a coating. An oil residuum passes from a tank A through a heater B to a mixer M in which it is mixed with liquefied propane under pressure admitted from a tank C.  The resulting solution flows into a chiller D where propane is vaporized to reduce the temperature, and the vapours flow through a pipe 18 to a condenser F and to the storage tank C. Further chilling in the vessel D is obtained by admitting chilled propane, e.g. at -60 DEG  from a tank E.  The wax and oil pass from the chiller D to a filter G of the rotary drum type operated under pressure and provided with propane jets 26 and a wax scraper 30.  Wax is removed and falls into a shoot 31, and the dewaxed oil is freed from solvent in a still H.  The wax-oil solution may first be chilled at the rapid rate to about 0 DEG  F., and chilled to a lower temperature at a slower rate.

Abstract: 1344808 Table football L ROBERTO 29 March 1972 [26 July 1971] 14647/72 Heading A6H [Also in Division G4] A coin freed table-football amusement machine includes model footballers (not shown) mounted for actuation on slidable and rotatable rods 20-34 extending across a playing surface 10; when a goal is scored by either player the ball passes through an opening 36 or 38 and is conveyed by a channel (84) or (86) Fig. 2 (not shown) to an electromagnetic device (88) which returns the ball into play through an aperture having a spring-loaded cover 73. Micro-switches (90), (92) in the channels are actuated by the passage of the ball to energise indicating lamps positioned beneath windows 40-50, 66-76, 52-64, 80 and 78 in the surface 10, thereby respectively to register each player's score, the number of balls that have been used in a game, the end of a game and the number of games left to play. An electrical control circuit, which can be mounted on a removable panel located beneath the surface 10, is described with reference to Fig. 3 (not shown). The coin operated mechanism is said to be of known type which will accept coins of two different values and which can be adjusted to change the number of matches accredited at each insertion of a coin, or the number of matches played for a certain price, and to change the number of balls for the game.

IPC: C09C1/36
Filed: 1953-05-26
Abstract: Titanium dioxide pigment material is calcined and wet milled; at least 0.1 per cent by weight of formic or acetic acid is added to form a flocculent which is then heated to 110 DEG -180 DEG C. to dry and remove the acid therefrom to form a water-dispersible pigment. Preferred features include use of formic acid in an amount of at least 0.12 per cent by weight after a hydroseparation of the finer particles (less than 3 microns) of the wet-milled material, followed by drying at 120 DEG C.; dispersing agents, preferably organic, such as mono- and triethanolamine and morpholine may be added prior to wet-milling (preferably 0.1-0.5 per cent by weight monoethanolamine) and also after drying and before or during a final milling (preferably 0.1-0.5 per cent by weight trimethanolamine).  In one example 0.05 per cent by weight of 2-amino-2-methyl-1-propanol was used in both milling stages.  The product may be used to improve latex paints, rubber goods and the opacity of paper.

May 26, 1932, No. 14947. Convention date, May 28, 1931. [Class 41.] A cell for the recovery of silver from solutions of its salts, particularly from spent photographic fixing baths, is divided by cathodes 15 and anodes 16 of sheet form into a set of compartments in each of which is situated a pair. of agitators each consisting of a set of radial arms 29 mounted on a shaft 28. The electrodes are provided with slots 44 for insertion over the shaft. For each compartment there is provided a side chamber 38 containing a filter consisting of a felt sock 45, through which the electrolyte is circulated. The returning electrolyte is delivered to each compartment just below the shaft by a channel 41 in a pipe 42. The pipe 42 is provided externally with grooves to receive the edges of the cathode slot and the anodes of carbon. The arms 29 and the shaft 28 are covered with rubber to prevent corrosion. The shaft 28 is mounted in bearings in the end walls of the cell, means being provided to prevent access of electrolyte to the bearings. Brown sulphide sludge from the filters 45 may be dried and sold to refiners or may be dissolved in nitric acid, re-precipitated with sodium carbonate and dissolved in fixing solution. The cathodes should be cleaned beofre starting with soap powder, rinsed, dried and polished with a rag moistened with petrol containing a trace of heavy oil. The electrolyte should contain at least one part in a thousand of silver. The starting current density may be 1 amp. per sq. ft. Directions are given for dealing with fouling of the electrolyte and electrodes due to excessive removal of silver. Each cathode is connected by a bar 17 to a clip 18 mounted on a panel 19 and thence through a resistance coil 21 and a conductor 3 to a bus-bar 25. The current may be determined by connecting a milli-voltmeter across the conductor 23. Each anode is connected by a flexible wire to a busbar 27. The cathodes are of stainless steel to permit stripping of the deposit.

Abstract: 598,198. Impedance-matching. SPERRY GYROSCOPE CO., Inc. June 18, 1945, No. 15499. Convention date, June 17, 1944. [Class 40 (iii)] [Also in Group XXXVI] A micro wave wattmeter comprises a liquid dielectric into which the micro waves whose power is to be measured are directed so as to be dissipated in the form of heat and means for measuring the rate of heating of the dielectric. In one application, the wattmeter which provides an enclosed concentric termination of an air-filled coaxial line includes a quarter-wave impedance matching section having a solid low-loss dielectric such as polystyrene, and an end section having a circulating liquid dielectric 4. In a modification, Fig. 3 (not shown), the sections with air solid and liquid dielectrics all have the same characteristic impedance, the portion with the solid dielectric then acts merely as a plug, its length is immaterial and the device is suitable for a wide band of frequencies. If water is used as the power absorbing dielectric in the latter device, the central conductor of this section must be extremely thin and it may be suitably reinforced, e.g. by a coating of polystyrene, Fig. 3a (not shown). In a further modification, Fig. 4 (not shown), the coaxial sections of Fig. 2 are replaced by wave-guide sections.

Title: System for the Instantaneous and Electrical Heating of Water.
Inventor: SEIMBILLE LOUIS ELIE
IPC: F24H1/10
Filed: 1918-09-25
Abstract: 119,474. Seimbille, L. E. Sept. 28, 1917. [Convention date]. Heating by electricity.-The resistance wire d of nickelchromium &c. is wound upon a core c secured at each end to the container and having sharp edges to allow of free circulation of water round the wire. The ends of the wire d are connected to upper and lower terminals f<1>. The switch h is connected with the water cock g and comprises two pairs of arms i, i<1> as shown in Fig. 2 so that the current remains constant irrespective of the position of the cock and the amount of water flowing through the heater. Water at various temperatures can thus be obtained by regulating the supply of water which enters at the lower end of the container and is delivered through an outlet c at the upper end. Specification 8395/13 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the heating wire may be of a metal which is not necessarily a poor conductor but whose resistance is greater owing to its small section. The wire may be protected by electroplating or enamel. The connexion between the cock and switch may be made by means of a cardan joint. A modification is described in which the water is heated by the current passing between two electrodes immersed in the water. The electrodes may be in the form of blades, disks or tubes and they may be separated by a diaphragm. In all the forms the delivery pipe is of greater section than the supply pipe. This subject-matter does not appear in the Specification as accepted.
