Title: Improvements in steering dampers for motor vehicles
IPC: B62D7/22
Filed: 1926-05-11
Abstract: 269,739. Poulet, E. May 11, 1926. Non - reactive steering - mechanism; steering- gear.-Comprise a pivoted arm which is connected to the steering wheels so as to oscillate therewith and is subject to great resistance to motion for small deviations from the central position but to little or no resistance at larger deviations. The resistance may be due either to hydraulic or solid friction. In the construction shown in Figs. 1 and 3 an arm d connected by a rod h to a steering stub-axle is fixed on a shaft c carrying a vane e which oscillates in a closed casing a bolted to the car axle j. In the central position shown a small space g is left between the ends of the vane and projections a<1> on the casing walls and liquid in the casing is trapped between the vane and fixed packing blocks f, being forced to pass through the passages g until the vane has moved past the projections. In the construction shown in Figs. 5 and 7 an arm 5 pivoted on the axle 9 has friction members 7 bearing against curved plates 2 pressed together by springs 11. The friction between the arm and the plates is greatest in the central position shown, and diminishes as the arm moves away from this position. Modifications of the second construction are described in which (1) the plates 2 are disc-shaped and the arm 5 has friction members on each side of its pivot, and (2) the arm 5 is double and has two friction members pressing on the upper and lower sides of a fixed plate having tapered ends.

IPC: C01B25/37
Filed: 1954-04-27
Abstract: Chromic orthophosphate (suitable for use in wash primers or metal conditioners and having corrosion resistant properties), orthophosphite and orthoarsenate are prepared by adding an alkali metal or ammonium sulphite and an alkali metal or ammonium bisulphite to a mixture containing an alkali metal or ammonium bichromate and phosphoric, phosphorous or arsenic acid respectively, while maintaining a pH of 1.0-4.5 Stoichio-metric proportions for the reaction: Na2Cr2O7.2H20 + 2H3PO4 + Na2SO4 + 2NaHSO3 + 6H20 --> 2(CrPO4.6H2D) + 3Na2SO4, (or the corresponding reactions involving phosphorous or arsenic acids) are preferred.  The initial mixtures of bichromate/acid and sulphite/bisulphite may have pH's of about 1 and 6.2 respectively, and the mixing of these solutions should take place slowly with agitation.  Suitable sulphite/bisulphite solutions may be obtained by adding 1 mol of sodium hydroxide (or equivalent sodium carbonate) to 3 mols of sodium bisulphite: alkali metal or ammonium may alternatiively replace sodium.  The chromic orthophosphate is in the form of very fine (e.g. 7m ) dark green amorphous particles.

Abstract: 558,338. Refrigerating. AKTIEBOLAGET ELEKTROLUX. Aug. 31, 1942, No. 12228. Convention date, Sept. 22, 1941. [Class 29] Absorption systems.-In a continuous-cycle inert gas system a body of liquor is disposed below the level of liquid in the absorber and is maintained at constant level by overflow arranged above the absorber level, whereby rapid starting after an idle period is facilitated. The body of liquor may be stored in one limb 111 of an inverted U-tube, of which the other limb 112 forms a generator welded to a flue tube 110. Strong liquor from an absorber vessel 116 flows through a conduit of a liquor heat exchanger 120 to an auxiliary pumping pipe 122 welded to the flue and is discharged into the store in the limb 111 as long as the pump 122 is in operation. The usual liquor circulating pump 114, also welded to the flue, raises liquor from the store to the top of the generator and weak liquor leaves the generator by the inner conduit of the heat exchanger at above the level of the lower end of the pump pipe 114. Vapour from the generator passes into the upper part of the limb 111, which serves as a rectifier and which may be provided with bafflles 123, and passes through an outermost jacket 124 of the heat exchanger for further rectification before passing by pipe 126 to the usual condenser. Condensate from the jacket 124 is led by a branch 125 to the store of liquid. In a modification the vapour flows through the jacket of the interchanger in counterflow to any condensate formed therein. The rectifier limb may be in heat conduction with the flue.

Title: Improvements in or relating to weft cutting mechanisms for weaving looms
IPC: D03J1/08
Filed: 1949-05-09
Abstract: 730,551. Weft cutting in looms. HRDINA, R. May 9, 1949 [May 7, 1948; Jan. 21, 1949], Nos. 12269/49 and 12270/49. Class 142(2). A weft cutting mechanism for a weaving loom having automatic bobbin change comprises a member 1 having a cutting edge and pivoted thereto a counter blade 2. The member 1 is pivoted at 3 and as it is swung forward the counter blade abuts against the rim 5 of the temple fixing and severs the end of the weft thread extending from the exhausted bobbin, and in a further movement the end of the thread from the newly supplied bobbin. The thread cutting is effected while the slay moves away from the beat-up position. In one embodiment (Fig. 3) the member 1 is operated by a lever 4 hinged at 16 and carrying a further lever 11 which engages an abutment 12 on the loom slay, the threads then being cut each time the slay moves to the rear. The mechanism operates twice at each bobbin change and is held inoperative by a hook 10 engaging a slide 9 linked by a lever 8 to the bobbin change rod 7. On rotation of the rod 7, the slide 9 moves forward and releases the hook 10 allowing the levers 4 and 11 to sink and engage the slay. In another embodiment (Fig. 6), the member 1 is engaged with the lever 4 by a pin and slot, and the drive for the mechanism is taken from the picking shaft 22 by means of a cam 21 and a follower 23 on a slide link 20 through a linkage 19, 18, 17. The mechanism is held inoperative by the  slide 9 engaging a pin 29 on lever 4, the motion of said slide being controlled by movement of the bobbin change rod, 7 and link 24.

Abstract: 117,524. British Thomson - Houston Co., (General Electric Co.). Aug. 27, 1917. Fluid governors.-One or more auxiliaries 5 of a main condensing engine or turbine 7 are driven by a non-condensing engine or turbine 9 up to a point at which its exhaust can be efficiently utilized for heating the feed-water and for other purposes, the remainder of the load of the auxiliaries being driven by an electromotor 8 connected to the main generator 6 driven by the engine 7. The auxiliary 5 shown in Fig. 2 is a direct current exciter for the main alternating current generator 6. The exhaust steam from the turbine 9 is led by pipes 12, 14 to a feed-water heater 13, Fig. 1. The admission of steam to the turbine 9 is regulated by a valve 22 controlled by a speed governor 25 and by a valve 23 connected to a device responsive to the temperature of the feed-water. This device may be a diaphragm 28 actuated by the pressure near the water-line 26 in the heater 13, Fig. 1, which pressure is stated to vary within limits with the temperature of the feed water, or the device shown in Fig. 3 may be employed comprising a movable abutment in a casing 33 connected to the valve 23 and subjected below to the pressure of a fluid in a tube 34 connected to a small tube 35 open at its lower end and sealed in a closed tube 36, which is exposed to the temperature of the feed-water. When the supply of exhaust steam exceeds that required for heating the feed-water, a vadve 23 in the steam supply pipe of the turbine is partially closed, and as soon as the speed falls below the synchronous speed of the motor 8, the latter comes into play and takes up the load the turbine 9 has dropped.

Title: An improved process for the catalytic alkylation of olefins with isoparaffins
IPC: C07C2/62
Filed: 1941-09-24
Abstract: 552,196. Hydrocarbons. STANDARD OIL DEVELOPMENT CO. Sept. 24, 1941, No. 12353. Convention date, Sept. 25, 1940. [Class 2 (iii)] In the alkylation of isoparaffin with olefines, the sulphuric acid catalyst after use in the reactor fed with the less active mono olefines-namely those with fewer than five carbon atoms-is used for the alkylation with the more active mono olefines. For the alkylation with butenes and lower olefines acid of 80-about 90 per cent. strength is used, and for higher olefines acid of 90-100.6 per cent. is suitable. The alkylation may be effected in the liquid or gaseous phase and temperature control may be obtained by evaporation of the lighter constituents, conveniently the excess isoparaffins. In an example, a refinery C4 feed containing butenes and isobutane is charged into two jet-type reactors and a refinery C5 feed charged to a third reactor. In order to maintain a high excess of isoparaffin, field butanes mixed with the liquefied, compressed light components distilled from the reactors are fed into the bottoms of the first and third reactors. The second butene reactor receives the total product and the unreacted hydrocarbons recovered from the settler adjoining the first reactor. Most of the acid in the emulsions circulating in the reactors is recycled but sulphuric acid is added to the acid withdrawn from the first two reactors to maintain a titratable acidity of 90 per cent. Spent acid recovered from the settlers adjoining the first two reactors is used in the third reactor.
