Patent GB-266640-A (GB)
Abstract: 266,640. Clavel, R. Sept. 17, 1926, [Convention date]. Yarns &c., treating with liquids.-In the weighting of natural silk in the form of skeins, or fabrics, the weighting agents which interact to form an insoluble substance, such as metallic compounds, salts, or tanning substances, are used in a bath in common instead of in separate batrs, the common bath containing one or more agents adapted to hinder precipitation, such as an acid, an acid salt, or a protective colloid. When the silk is treated in the bath, precipitation occurs only on the fibre but not in the solution. Two or more weighting baths may be employed, the transference from one bath to another being effected without washing, acidifying, or neutralizing. After treatment in the weighting bath or baths, the silk may be put in a press and, before drying it, it may be treated in a bath containing ammonium carbonate and, if desired, dyestuffs containing tanning substances, such as haematein. In an example, silk fabrics are drawn three times through a bath containing tin tetrachloride, orthophosphoric acid, and aluminium sulphate, the process being completed by passing the silk through a bath of water glass. In another example, the weighting-bath contains tin tetrachloride, formic acid, water glass, sodium phosphate, and glue. After subjecting boiled off silk to the bath, it is pressed, drawn through an ammonium carbonate bath, and dried. The silk is then washed in a soap bath containing haematein and dyed.

Title: Improvements in superchargers for aircraft engines
IPC: F02B33/00
Filed: 1939-10-02
Abstract: 534,240. Pumps. BRADBURY, F. Oct. 2, 1939, No. 26981. [Class 7 (ii)] A supercharger for aircraft engines is driven by a direct current series wound motor through gearing, so that the speed of the supercharger increases with decrease in load due to rarefication of the air as the altitude increases, thus maintaining the engine output. The impeller A is driven from the motor D through gearing C, C<1> and a slipping clutch or spring drive B. A governor F is arranged to break the circuit of the motor if the speed should become too high. A further governor H may be arranged to switch in an additional supply of current to give a boosting effect, either at low or high speeds ; or the boosting may be obtained by means of a rheostat controlled by the pilot. A compound wound motor may be used, in which the series winding is large in comparison with the shunt winding, the latter serving to prevent the motor from racing.

Title: Printer mechanisms
IPC: G06M3/06
Filed: 1962-07-13
Abstract: 962,365. Meters; printing. ROCKWELL MANUFACTURING CO. July 13, 1962 [Sept. 18, 1961], No. 27016/62. Heading G4D. [Also in Division B6] The invention relates to printing apparatus, particularly in liquid dispensing meters, the total on the counter being printed both before and after metering. Provision is made for reverse flow. Figs. 1, 4 and 17 show the initial position of the mechanism. A carbon-backed ticket is placed through jaws 151, 152 to abut against a stop 161, Fig. 5. A counter-clockwise rotation of handle 18 rotates control shaft 19. Initial movement of cam 188, Fig. 3, operates a punch 180, Fig. 5, to hold the ticket securely until the handle 18 is returned at the end of the whole operation. Continued movement of handle 18 actuates cam 165, Figs. 5, 6, to raise ticket-tray assembly 15, after which printing control cam 210 retracts and releases printing hammer 200, Figs. 4, 5, whereupon a "before metering" record is made. Metering then takes place in forward or reverse direction and the handle 18 is rotated in a clockwise direction. Due to lost-motion in the drive to control shaft 19 the ticket-tray assembly 15 is lowered before the "after metering" record is made. Withdrawal of the punch 180 permits removal of the ticket. Meter drive to counter, Fig. 19. This drive includes a resilient lost-motion connection 224 permitting movement of the lowest order wheel to full number position before printing by pawl 232, Fig. 14, controlled by cam 238. When the printing hammer returns it disengages spigot 237 from detent recess 242 to withdraw the pawl 232, so permitting rotation of the counter. The print includes apparatus identity on wheels 12 and also consecutive numbers on wheels 13, Figs. 1, 12. The lowest denomination wheel 13a is advanced half a step by arm 250 cammed by member 259 during the first rotation of the meterdriven shaft 14 provided the meter is operating in a forward direction. If the meter is operating in reverse spring clutches 261, 262 are inoperative, member 259 providing additionally a positive stop. Return of control handle 18 rotates correction bracket 231 to advance the wheel 13a the extra half-step by means of pawl 269 and ratchet 252. Unidirectional control, Fig. 16. To ensure that the control handle 18 and shaft 19 are turned the full amount first in one direction and then the other, a gear 280-on shaft 19 has an area 282 free of teeth whereby detent 283 will prevent too early reversal of rotation.

Title: Process for the preparation of propylene chlorhydrin
Inventor: FERRERO PAUL
IPC: C07C29/66
Filed: 1952-10-28
Abstract: <PICT:0738171/IV (b)/1> A continuous process for preparing propylene chlorhydrin from water, chlorine and propylene is characterized by operation at a temperature below 60 DEG  C., with a volume of propylene-containing gas of which a maximum of 50 per cent is consumed in the reaction, in an apparatus comprising two distinct superposed reaction zones; the first said zone for dissolving the chlorine in the propylene chlorhydrin aqueous solution, the second said zone for reacting the chlorine-containing solution with the propylene and piping connecting the top of the second zone with the bottom of the first zone, said apparatus affording gravitational recirculation of the chlorhydrin solution between both reaction zones in consequence of the buoyancy of both gases introduced and of the different densities of the gaseous dispersion in the reaction zones on the one hand and of the liquid in the recirculation piping on the other hand whereby the concentrations of free dissolved chlorine and of chlorine transformed into hypochlorous acid taken together and expressed as chlorine are maintained at a value lower than 0.5 gram per litre.  An excess of propylene compared with the introduced chlorine may be employed or a diluent may be used, e.g. a paraffin hydrocarbon such as ethane, propane or the butanes usually accompanying propylene in the fraction of liquefied petroleum gases rich in this olefine or any other gas inert under the reaction conditions such as methane, hydrogen or nitrogen.  The apparatus in the drawing is filled to the upper level of tube 10 with an aqueous solution containing propylene chlorhydrin whilst a stream of chlorine gas is introduced into column 1 through porous plate 2, with the formation of hypochlorous acid which reacts in column 3 with diluted propylene introduced through porous plate 4.  The solution of propylene chlorhydrin is partially withdrawn through tubing 10 and partially recirculated through tubing 5, water being introduced at 6 at a rate corresponding to the rate of withdrawal through 10.  The solution is recirculated through tubing 7 and adjustment device 8 to column 1.  The residual gases are recovered at 9.  In the examples: propylene chlorhydrin is produced using the above apparatus and as propylene containing starting material a mixture of propylene, propane and hydrocarbons having four carbon atoms (1); and a mixture of propylene, ethylene, ethane, propane and butanes.

Abstract: 665,825. Checking picking sticks. WEATHERHEAD CO. Oct. 10, 1947 [Oct. 12, 1946], No. 27256/47. Class 142(iii) [Also: in-Group XXXII] A hydraulic checking device for a picking stick gives a checking action to the power stroke and to the return stroke of the stick, the checking action of the return stroke being maintained constant by means of a tapered metering pin. The picking stick is connected by a rod 15 to a lever 16 pivoted at 60 and connected at 62 to a piston P, one end 23 of the piston sliding in a cylinder 21 and the other end 26 sliding in a cylinder 25. During the power stroke, the end 23 enters the cylinder 21 and fluid passes through ports 34 to a reservoir 24. When the ports 34 are closed by the wall of the cylinder, any additional fluid displaced passes along a passage 35 having a metering screw 36 and checks the picking stick. A return spring on the picking stick is balanced by a spring 30 which holds the stick in an intermediate position near the point of commencement of the hydraulic checking action for the return stroke. On the return stroke, the end 26 moves into the cylinder 25, fluid flows through the ports 40, 44 until the ports 44 are closed by the wall of the cylinder. The fluid passing through the port 40 is decreased by a tapered metering pin 47 which can be adjusted by a member 50 remotely controlled by a flexible drive. Specification 657,536, [Group XXXI], is referred to.

Title: Improvements in or relating to extreme pressure lubricating oil compositions
Filed: 1945-10-18
Abstract: An extreme pressure lubricating composition comprises a lubricating oil to which is added a compound of the general formula <FORM:0604388/III/1> where x is an integer and R an alkyl group. Such compounds are the chlorbenzyl esters of alkyl xanthic acids. The lubricating oil may be a light petroleum hydrocarbon, benzene or any of its homologues, an alcohol, ether or ester, fatty vegetable or mineral oil or a mineral hydrocarbon or the like, the additive being dissolved, dispersed or emulsified according to the oil used.  The additive is present in the minor amount, usually 1-10 per cent, and preferably not less than 7 per cent, though more concentrated compositions, say 50 per cent, may be prepared and diluted immediately before use to about 7 per cent.  Any chlorbenzyl xanthate may be used, such as trichlor-, dichlor- or o-chlorbenzyl sec-butyl xanthate, tetrachlor-, trichlor- or o-chlorbenzyl isopropyl xanthate, or the trichlorbenzyl esters of octadecyl, heptadecyl, tetradecyl, dodecyl, decyl, octyl, heptyl, hexyl, amyl, ethyl and methyl xanthic acids.  In an example, trichlorbenzyl ethyl xanthate (for preparation see Group IV (b)) is added to high viscosity mineral lubricating oil and tested by standard methods for determining the extreme pressure characteristics.  Specification 604,370 is referred to.ALSO:Chlorbenzyl esters of alkyl xanthates of formula <FORM:0604388/IV(b)/1> are prepared by reacting a chlorbenzyl chloride with an alkali metal xanthate and separating the alkali metal chloride formed. In an example, 460 parts of trichlorbenzyl chloride (2.0 molecular proportions) are added in a slow stream to sodium ethyl xanthate prepared by reacting 190 parts (2.5 molecular proportions) of carbon disulphide, 91.5 parts of 96.5 per cent caustic soda (2.2 molecular proportions) and 808 parts of ethyl alcohol.  (All parts are by weight.)  The temperature is maintained at 50-55 DEG  C. during the addition of the chloride, and then the mixture is refluxed for about an hour.  Excess alcohol is removed under vacuum and the residue washed with water and dried.  The trichlorbenzyl chloride used is prepared by nuclear chlorination of dry toluene (1500 parts) at 20 DEG  C. in the presence of iron filings (15 parts) increasing the temperature to 70 DEG  C. during the last part of the run, and the purified product chlorinated in the presence of ultra-violet light at 160 DEG  C. until the gain in weight was that calculated for trichlorbenzyl chloride.
