Title: Precipitation of vanadium oxides from aqueous solutions
IPC: C01G31/02
Filed: 1953-08-21
Abstract: A vanadium oxide or mixture of oxides which may in general have a composition varying between V2O2 and V2O3 is precipitated from neutral or basic aqueous solutions containing vanadium in pentavalent form by heating the solution in a closed reaction zone in the presence of a hydrogenation catalyst under a partial pressure of hydrogen of at least 3 lbs./sq. in. at 125-400 DEG  F.  The original solution may contain compounds such as NaVO3, NH4VO3, or V2O5, and preferably also an electrolyte such as sodium sulphate, carbonate, bicarbonate or hydroxide.  Catalysts specified are nickel and cobalt, the former being preferred, and used commercially in amount not less than about 0.5 g./l. solution.  The preferred temperature range is 250-350 DEG  F.; below 200 DEG  C. the rate of precipitation is very low.  In the example V2O3 is produced using nickel as the catalyst at a temperature of 300 DEG  C. and a partial pressure of hydrogen of 300 p.s.i.  The nickel was separated magnetically and re-used.

Title: Process and apparatus for producing unsaturated hydrocarbons
IPC: C07C2/78
Filed: 1959-07-07
Abstract: <PICT:0865336/IV (b)/1> In the production of acetylene by partial combustion of hydrocarbons, mixed hydrocarbon and oxygen are sucked off from the periphery of the mixing zone before the reaction zone. In Fig. 1, preheated methane and oxygen enter by pipes 5 and 4, and in the diverging section the peripheral gases are sucked through holes or slots into chambers 6, where they may be quenched.  The chambers 6 may contain filler bodies.  The reaction occurs in zone 9 and is quenched by water injected through a vertically adjustable spray 14.  The sucked-off gases may be used as fuel for preheating or may be injected into the reaction chamber along the wall throug slots 19 (Fig. 2 not shown).

Title: A process of protecting dairy products and margarine against acquiring unpleasant flavour
IPC: C11B5/00
Filed: 1949-09-09
Abstract: Butter and margarine are treated against acquiring unpleasant taste or flavour by adding in small amounts a protective agent prepared by subjecting at a temperature from 80-95 DEG C. and with exclusion of air, an aqueous solution of one or more reducing sugars such as lactose, grape-sugar, galactose, xylose or fructose to successive treatments with alkali in successive quantities to bring the pH of the solution to and to maintain it during the treatment at, at least 9 and preferably not exceeding 11.5, the treatment at the said pH being thus prolonged for a sufficient period to impart the desired protective properties to the treated sugar solution.  The pH is finally adjusted preferably by HC12 to about 6.8.  The protective agent may be added in solution or powder form at a preliminary stage of the preparation or manufacture of the product, e.g. it is added to the cream in the proportion of 2-10 parts by weight to 10,000 parts by weight of the cream at the time of its acidification or immediately before the churning in the preparation of butter from cream by churning.

Title: Improved shock absorber
IPC: F16F9/48
Filed: 1962-06-19
Abstract: 960,044. Hydraulic shock-absorbers. FORD MOTOR CO. Ltd. June 19, 1962 [June 30, 1961], No. 23478/62. Heading F2S. An hydraulic shock-absorber which is designed to provide soft operation for normal, and firm control for extreme, deflections and which is provided with final hydraulic lock comprises a non-valved piston 14 which is slidable within a pressure tube 12 and divides the latter into rebound and compression chambers 25, 27 which communicate with each other through two independent passages 56, 58, each of which is only in operation during a corresponding compression, on rebound, stroke of the piston 14. The passages 56, 58 which are formed between diametrically opposed flats 52, 54 on the tube 12 and a surrounding secondary tube 20, communicate at their lower ends with ports 70, 68 leading respectively to low-pressure compression and rebound valves 44, 42 located in a base valve block 38 which seals the lower end of the tubes 12, 20. The chambers 25, 27 have respective series of high-level orifices 66, 64, which open into passages 58, 56. The base valve block 38 also accommodates a spring-loaded replenishing valve 40 which connects the chamber 27 to a reservoir 23 provided by the annular space between the tube 20 and a surrounding reservoir tube 22. An upper head-piece 24, which seals a piston-rod 16 and the upper end of the pressure tube 12, has a number of ports 60 which are controlled by a spring-loaded valve 62 and provide controlled communication between the rebound chamber 25 and the passage 56. During a rebound stroke fluid is forced from the rebound chamber 25 through the orifices 66 into the passage 58 and past the valve 42 into the compression chamber 27, the remainder of the replenishing volume being drawn through the valve 40 from the reservoir 23. An additional free-flow orifice 72 may be provided in the lower end of the tube 12. When the piston 14 descends fluid flows through the orifices 64 to the passage 56 some of the fluid being forced upward past the valve 62 and into the rebound chamber 25 and the piston-rod displacement fluid passing through the valve 44 to the reservoir 23. Successive closing of the parts 64, 66 at the end of each stroke provides high level damping and final hydraulic lock. In a modification the pistonrod is provided with an attachment ring and also a dust tube.

Title: Improvements in sound-reproducing apparatus
IPC: H04R9/06
Filed: 1924-10-07
Abstract: 231,420. British Thomson-Houston Co., Ltd., (Assignees of Kellogg, E. W.). March 27, 1924, [Convention date]. Magnetic instruments; diaphragms; loudspeakers.-A diaphragm adapted to vibrate as a whole is suspended so that its natural frequency is below the lowest important voice frequency. The first overtone is preferably above the voice range. In a moving coil instrument, the diaphragm is either in the form of two intersecting conical surfaces, Fig. 3, or parabolic, Fig. 4. The coil 2 is secured to a ring 6 which in Fig. 3 is secured to the diaphragm at the intersection of the two surfaces. The diaphragm is mounted by being secured to a rubber ring 8, Fig. 3, or by four threads 16, Fig. 4, adjustable in tension by means of screws 17. The air space behind the diaphragm is reduced by a plate 10 attached to the outer pole-piece 4 to raise its resonance above the voice frequencies, and vents 11 are formed in the plate 10 in order to reduce the sharpness of resonance. The air between the coil an'd the inner pole is vented by holes 9 in the ring 6. The air spaces may be damped with sound absorbing material. The form shown in Fig. 3 is used with a baffle-board 12, as described in Specification 231,421, but may be used with a horn. The form shown in Fig. 4 is used with a horn 14 with which a passage 13 down the inner pole-piece communicates. A cap 19 of non-magnetic material is secured to the inner pole-piece to reduce the air cavity at the entrance to the horn and a similar device may be used with the form shown in Fig. 3. The magnet used in either form may be a permanent one or mav be magnetized by a coil 5. If rectified alternating-current be supplied to the coil 5, the end 20 constitutes a shortcircuited turn of low-resistance by making it of copper. This may constitute the spool head, as shown, or may be spaced from it. and serves to steady the pulsating current. The spool head furthest from the air gap is either of iron or of non-conducting material. Specifications 227,162 and 229,759 are referred to.
