Title: A process for the production of aromatic nitrogen-containing hydroxy compounds
Filed: 1941-04-21
Abstract: 548,554. Fatty oil compositions; soaps; hydrocarbon oil compositions; liquid fuels. FIFE, J. G. (Shell Development Co.). April 21, 1941, No. 5142. [Class 91] [Also in Group IV] Compounds which may be added to gasoline and other hydrocarbon oils, soaps and animal or vegetable oils or fats, to protect them from the catalytic effect of metal oxidation promoters, have the formula HO.X.CH:N.ROH, where X is aryl, OH is ortho to the other group and R is an aliphatic radical which may contain N in the chain. They are prepared by condensing an aromatic ortho-hydroxy substituted aldehyde with an equimolecular amount of an amine H 2 N.ROH. Thus salicylal mono-ethanol amine is prepared from salicylaldehyde and ethanolamine and N -salicylal- N' -ethanol ethylene diamine from salicylaldehyde and ethanol ethylenediamine. Other compounds which may be used are salicylal propanol and dodecanol amine or ethylene diamine or its naphthyl and anthryl derivatives, e.g. #-hydroxy-#-naphthylal ethanol amine.

Title: Torque transmission system
Inventor: BLACK JAMES BENJAMIN
IPC: B61C9/14
Filed: 1968-02-01
Abstract: 1,214,744. Change-speed and clutch control. TWIN DISC Inc. 1 Feb., 1968 [14 Feb., 1967], No. 5258/68. Headings F2D and F2L. A variable speed drive e.g. for a rail vehicle, comprises a single speed gas turbine GT connected through a speed reduction gear SR, a variable slip, constant output speed clutch MC and a torque converter TC to a change-speed gear-box GB of the type having two forward and two reverse speeds selected by hydraulically operated double clutches C, C1. Hydraulic fluid for the system is supplied by a pump P, driven by the clutch input member, the flow being divided by a valve 54 so as to supply the torque converter, a modulating valve 58 and a regulator valve 62 through lines 56, 59 and 60 respectively. Clutch control.-Valve 58 controls the supply to the clutch MC and comprises a pressure regulator 68 feeding a spool 73 controlled by three solenoid-operated valves 80, 81 and 85. Actuation of either of valves 80, 81 or both together forces spool 73 to the right in the Figure against spring 74 to produce different pressure levels in the line 63 and therefore variable engagement of the clutch. A throttling orifice 77 in the exit from chamber 78 behind spool 73 slows the movement of the spool to control the rate of rise of pressure thereby producing smooth clutch engagement. A speedresponsive governor valve 86 is provided to vent the system if the turbine speed falls too low. The clutch has a centrifugal valve 10 which exerts an overriding control on the fluid pressure in line 63 to produce a constant output speed. Gear-box control.-The regulator valve 62 controls the fluid supply through line 99b to four solenoid-operated valves 95-98, a fifth valve 99 acting on valve 62 to control the rate of rise of pressure in line 99b. Each of said valves 95-98 controls one of the clutches of the speed selecting double clutches C, C1. Appropriate energization of the solenoids of valves 80, 81, 95-98 is effected by movement of the driver's control handle to select a particular speed. Gear-box.-The output shaft 24 from the torque converter drives reverse and forward lay shafts 32, 33 through constant mesh gears 27, 28, 29 and 27, 30 respectively. Shaft 32 carries the double clutch Cl, the clutches 36, 37 thereof being connectible to the two reverse speed gears 40, 41 which are in constant mesh with gears 43, 44 on the output shaft 42. These gears are also in constant mesh with the two forward speed gears 38, 39 carried by the clutches 34, 35 of the clutch C on shaft 33. A method of operating two of the above systems in a rail car is described in the case where both systems are driving the car at low gear. To effect an upward shift, the clutch MC of the first system is disengaged and a highspeed gear clutch engaged at reduced pressure. This pressure is then increased to fully engage the clutch and then clutch MC is fully reengaged. The second system is then shifted in the same way.

Title: Means for restoring normal circulation in animal bodies in cases where the animal system has been subjected to circulatory shock
IPC: A61H31/02
Filed: 1942-04-22
Abstract: 556,862. Respiratory appliances. TRUBENISED, Ltd., and BIHALY, L. April 22, 1942, No. 5406. [Class 81 (ii)] Apparatus for maintaining or restoring normal blood circulation when the circulatory system has been deranged by shock comprises a bag or suit 1 for application to the patient under treatment with means for applying air under pressure to the suit, a breathing mask 7, adapted to be applied at will, connected to the source of air pressure and an automatic valve 6 operating to maintain constant the pressure balance between he tintrathoracic and venous pressures so that the venous pressure is at all times maintained in excess of the intrathoracic pressure by an amount sufficient to ensure satisfactory blood circulation whether the patient is breathing normally at atmospheric pressure or at an adjusted pressure through the mask. As shown a container 2, Figs. 1 & 2, which may be mounted on a wheeled carriage, has an hermetically sealed cover 12 carrying the tubes 4, 7a, a switch 27 for controlling a fan 3 and mountings for the means controlling the valve 6 which is carried by a pivoted lever 16 having an extension engaging a roller 23b on a pivoted lever 23a connected to a rod 20, connected to the ends of bellows 19 arranged on each side of a dome 18 on the cover 12. The rod extends through the end of one of the bellows and carries a roller 21 engaging the face 24 of a weighted lever 23 pivoted on a bracket 22 on the top of the cover 12. By adjusting the weight 26 on the lever 23 the position of the valve 6 is varied to give the required difference of pressures, the valve opening to bypass to the container the air in excess of that required to maintain the desired pressure in the suit during normal periods and ensuring the necessary reduction in pressure in the container during the abnormal periods. A valve 8 on the suit 1 is closed so that during normal periods, while the patient is eating &c., the intrathoracic pressure is atmospheric and the venous pressure is artificially maintained at a slightly higher pressure by the valve 6 ; during abnormal periods, when the patients wounds have to be dressed, the mask is fitted over the mouth and noses' of the patient, the valve 8 is opened so that the pressure in the suit gradually falls to atmospheric, the suit is removed from the patient, and the valve 6 closes to an extent such that the intrathoracic pressure is maintained at the required pressure lower than the venous pressure which is now atmospheric.

Title: Improvements in or relating to magnetic core structures for electrical induction apparatus
IPC: H01F27/25
Filed: 1946-02-21
Abstract: 608,378. Transformers; inductances. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 21, 1946, No. 5452. Convention date, March 3, 1945. [Class 38 (ii)] In a 3-phase laminated core structure comprising parallel leg portions 23-25 which are cut through transversely at 14 and machined to form butt joints, and at the ends of the leg portions have yokes comprising respectively two short arch-shaped yokes 26, 27 surmounted by an arched yoke 28 of greater span, and yokes 29, 30 surmounted by a yoke 31, with a surrounding band 21 of resilient material which is tensioned to clamp the parts together and maintain substantially constant pressure at the butt joints, additional means are provided for applying pressure on the butt joint in the middle leg portion 24. The additional pressure may be obtained by inserting blocks 35, 36 of wood or other material between the band' 21 and the central portions of the yokes 28, 31, and the blocks may be shaped so that an equal force is applied at the three butt joints in the core legs 23-25. Alternatively, a wedgeshaped block of a length equal to the width of the laminations may be inserted in each of the triangular gaps between the short yokes 26, 27 and 29, 30, and a tensioned steel band or loop is clamped around the outer faces of the wedges to exert a predetermined force on the adjacent parts of the laminations comprising the centre leg to maintain the desired pressure on opposite faces of the butt joint. A similar result is achieved by welding bridging strips 51, 52, Fig. 6 (not shown), across the aligned outer strips of the smaller yokes and clamping them towards one another by a tensioned band or loop disposed at right angles to the main outer band 21. In a further modification, Fig. 8 (not shown), a series of steel strips or inserts 61 are positioned between the laminations of the outer yoke portions 13, these strips being of lengths which decrease progressively from the inner to the outer portions of the said yokes. The core may be wound from continuous strips of magnetic material formed into loops with bonding material between the several turns, the loops being cut across to form butt surfaces between which thermoplastic material such as a vinyl acetate resin is inserted before clamping them together. Specification 540,662 is referred to.

Abstract: 795,747. Desulphurizing. ESSO RESEARCH & ENGINEERING CO. Feb. 22, 1956 [March 7, 1955], No. 5483/56. Classes 50 and 55 (1). Briquettes or pellets comprising coke obtained by coking heavy hydrocarbon oils in a fluidized coking process and an agglutinating carbonaceous binder, e.g. pitch, are desulphurized by contacting them with a hydrogen-containing gas at a temperature between 1200-1600‹ F. for 1 to 10 hours, the hydrogen-containing gas being utilized in an amount between 10 and 5000 v/v/hr. based on the briquettes or pellets being treated. A preferred treatment is carried out at 1300-1500‹ F. for between 2 and 3 hours. The treatment may be effected at superatmospheric and may be preceded by a treatment, preferably fluidized, with oxygen at between 600‹ and 1000‹ F. or with steam at between 1200‹ and 1800‹ F. The desulphurized briquettes or pellets may be calcined at a temperature above 2000‹ F. in an atmosphere of nitrogen, steam, or a limited amount of air. In an example, briquettes of cylindrical shape and made from a heavy oil coke containing 7 per cent sulphur were found after treatment for 4 hours with hydrogen at 1400‹ F. to contain 3.63 per cent sulphur.

Title: Improvements in manoeuvre signalling devices for use on road vehicles
IPC: B60Q1/36
Filed: 1942-04-29
Abstract: 554,644. Road traffic signals. SAXBY, R. N. April 29, 1942, No. 5731. [Class 118 (ii)] A manoeuvre-signalling device for use on road vehicles comprises a signalling arm which can be rotated to give an "overtake" signal but can also be arrested in its highest position to give a "turning" signal. The arm 1 is mounted on or forms part of a tubular shaft 2 which is inclined at an angle of 45 degrees to the arm and is journalled in a bearing 3 that is pivoted at 4. The shaft also carries a crank pin 6 which is connected by a rod 7 with the plunger 8 of a solenoid 9 and also co-operates with a fixed plate 12 provided with a slot 13 in a vertical plane. A cam 10 secured to the shaft actuates contact springs 11 in the circuit of the solenoid. Normally, the crank pin 6 rests in the slot 13, but on completion of the circuit, the solenoid is energized and pulls the crank pin downwards until it leaves the slot 13. As a result, the arm 1 is swung forward a little way until it is out of its casing' and then, the crank being free of constraint by the slot 13, the arm 1 is caused to rotate about the axis II-II. As the arm rises to its highest position, the cam 10 opens the contacts 11 and the solenoid is de-energized, but the arm has enough momentum to continue its rotation until the contacts 11 are closed again, and rotation continues. Thus the arm gives an "overtake" signal. In order to give a "turning" signal, the driver operates a separate switch that short-circuits or otherwise renders ineffective the contacts 11 in order to energize the solenoid steadily and thus hold the arm in its raised position. A resistance may be included in the circuit to reduce the drain on the battery.

Lugs 35 on the band 30 engage slots 36 in the radial flange 23 of the washer 22 and a ferrule 31 carried by the inner flange of the diaphragm 26 is urged axially by a coiled spring 34 thereby urging the sealing face 24 of the washer 22 into rubbing contact with a radial face 25 of a ball bearing 12. The seal is assembled in a retainer 20 one radial flange 37 of which limits the axial movement of the washer 22 out of the band 30. The retainer 20 may be omitted and the said axial movement of the washer limited by an inward flange at the outer end of the band. The coiled spring 34 may be replaced by a leaf type spring or the ferrule 31 may have a finger type spring integral therewith.

Abstract: 904,402. Washing granular material. BETEILIGUNGS - UND PATENTVERWALTUNGSGESELLSCHAFT. Feb. 16, 1961 [Feb. 17, 1960], No. 5801/61. Class 82 (2). A heavy liquid separator, particularly for use in coal washing, comprises a wheel including an imperforate disc 1 with peripheral cells at both sides, separating chambers 7, 17 on opposite sides of the wheel and a packing 16 isolating the chambers from one another. The cells are each comprised in a sieve plate 5, the disc 1 and a sheet metal ring 11. The chambers 7, 17 contain heavy liquid, which may be of different specific gravities, and are separated from the wheel by separating plates 10, 20. The bottoms of the chambers slope at an angle of at least 40 degrees to the horizontal, and the double arrangement provides a bath of heavy liquid which is relatively shallow for a large surface area. The ore is introduced into either chamber and the floating material is removed by a scraper from the surface of the liquid. The heavy material slides down into the cells of the wheel 26 which, by its rotation, discharges it through shoots 12, 25. The heavy liquid carried by the material falls through sieves 27 on to deflector plates 28 for return to the spaces between the disc 1 and separator plates 10, 20.
