Patent GB-459117-A (GB)
Title: A process for the production of alkyl ester salts
IPC: C07C303/24
Filed: 1935-06-27
Abstract: Absorption products of olefines in oxygen containing inorganic polybasic acids are diluted with water or an aqueous solution or extracted with organic solvents to separate the neutral alkyl esters from the free polybasic acids, acid alkyl esters or neutralization products thereof and the neutral esters are then treated with alkaline agents to give alkali salts of the corresponding acid alkyl esters.  In a modification, the free polybasic acids are substantially removed from the absorption products before separation of the neutral esters.  The olefines may be derived by distillation, dehydrogenation, cracking or other pyrogenetic treatment from petroleums, shale oil, natural gas, coal, peat, or animal or vegetable oils, fats or waxes.  In an example, water is added to an absorption product obtained in a continuous process from a cracked paraffin wax and sulphuric acid, so as to produce a lower layer comprising 69 per cent sulphuric acid.  By the addition of aqueous alcohol to the upper layer, neutral alkyl sulphates and polymerization products are separated which on heating with caustic soda yield a soap.  The free sulphuric acid may also be separated in the preliminary step by adding alkali or Glauber's salt solution. The separation is facilitated by the presence of ether or amyl alcohol.  The alkyl sulphuric acid salts obtained may be used as wetting and emulsifying agents in the textile industry and also as levelling agents, flotation agents and spray oils.  Reference is made to their use for greasing leather, preparing finely divided pigments and dispersing paraffin, tar and asphalt.  A sample furnished under Sect. 2 (5) is prepared from a gasoline fraction obtained by cracking paraffin cakes and sulphuric acid. Water is added to the absorption product to separate the dialkylsulphates which after washing with water to remove residual sulphuric acid are heated with alcoholic caustic soda to give sodium alkyl sulphates.  Small quantities of alcohols and polymers are removed by extraction with benzine.

Title: Improvements in reels for fishing rods
IPC: A01K89/015
Filed: 1928-08-27
Abstract: 320,998. Horrell, R. L. Aug. 27, 1928. Reels and winches, rod.-A reel has means by which its winding handle can be thrown out of engagement with the spool, a check device to retard the running of the spool which is more effective in one direction than the other, and an automatic breaking means whereby rotation of the spool is stopped when the line becomes slack. A hollow core 1 with domed ends 2 is keyed to a spindle 3 mounted on ball bearings. Casing members 5, 6 are recessed to receive the domes and are covered by plates 13, 14. The engagement of the winding handle is effected by movement of a lever 18 carrying a cam 17 which co-operates with a spring 19 in moving the crank lever 16 from the full to the dotted position shown in Fig. 2 and thus throws a pinion fast to the winding handle 23, out of mesh with a gear wheel 22 fast to the spindle 3. A projection 25 limits the movement of the lever 18. The checking of the spool is effected by a pawl 26 mounted to slide freely on a pin 28 in the casing and held in a balanced position by springs 29 adapted to pull the pawl into engagement with an escapement wheel 32 fast on the spindle 3. The teeth of the wheel 32 are shaped so that the check is greater in one direction that the other. The pawl 26 has a flanged end 33 which co-operates with a cam 44 mounted on the cover plate 13 and operated by a head 45 which when rotated puts the pawl in or out of engagement. The automatic breaking means comprise a wire yoke 34 pivotally mounted on a rod 35. Projections 36 of the yoke engage the casing 5, 6 under pressure of a spring 37. Attached to the rod 35 is a rod with an arcshaped extension 39 lying at an inclination to the wall of the casing. When the line is taut the wine yoke is turned so that the extension 39 assumes the position shown full in Fig. 2 and lifts a fibre brake shoe 42 held by a spring blade 40 from the dome 2.

Title: Improvements relating to electric traction control equipment
IPC: B60L7/22
Filed: 1938-08-23
Abstract: 517,898. Master control of D.C. motors. HIGGS, G. R., GRAY, W. T., and METROPOLITANVICKERS ELECTRICAL CO., Ltd Aug. 23, 1938, Nos. 24814 and 31158. [Class 38 (iii)] A compound wound traction motor M, Fig. 1, has its field resistance Sg varied by a regulator RG differentially driven by pilot motors X, Y. The motor X runs at a speed determined by line voltage and the motor Y at a speed determined by motor voltage when line switch LS is open, .and hence regulator RG is moved to keep the motor voltage equal to the line voltage. When switch LS is closed the speed of the motor Y also depends upon the armature current of the motor M acting through field winding Ye and the position of slider on resistance Yr, the regulator then maintaining constant motoring or regenerating current through the armature M. The regulator also controls the armature resistance R during acceleration. A control system for four motors is described in which two degrees of acceleration and braking can be used and rheostatic braking is instituted when regenerative braking ceases. Fig. 3 shows the motor circuit during braking, regenerative current follows the full arrows and after switch b' is closed and the line switches opened, rheostatic current follows the dotted arrows. The armature resistances are shorted progressively, from one end during acceleration and from the other end during rheostatic braking, by electromagnetic contactors controlled by the differential requlator. Fig. 2, shows a differential controller comprising a slider T housing intermeshing gears PX, PY, one being on a screwed shaft driven by the motor X and the other being splined to a shaft driven by the motor Y:

Title: Improvements in or relating to a process of standardizing dairy products and the products resulting therefrom
IPC: A23C15/02
Filed: 1947-09-10
Abstract: 666,631. Butter and milk fat concentrate. CHERRY-BURRELL CORPORATION and SUGAR CREEK CREAMERY CO. Sept. 10, 1947 [Sept. 7, 1942], No. 24841/47. Class 84 The composition of a product containing milk fat in the continuous phase which has been obtained by a continuous process from a dairy poduct containing milk fat in the dispersed phase is adjusted by blending the dairy product with an aqueous solution containing standardizing ingredents while maintaining the product at a temperature above the melting point of the milk fat and concurrently agitating the mixture sufficiently to maintain a uniform dispersion, and then cooling the mixture to a temperature at which it is substantially shape-retaining. The milk fat and standardizing ingredients are preferably blended at a temperature of 110‹F. and then cooled to below 60‹F. The standardizing ingredients may include salt, colouring, flavouring, starter solutions, and acid neutralizing solutions. In a preferred apparatus the dairy product is fed from storage tank 10, Fig. 1, fitted with agitating and heat exchange means into an acid neutralizing vat 17, into which caustic soda, caustic potash or lime water may be added. The neutralised product is then discharged through filter 24 to a prechurn 26 which may be of the types shown in Figs. 3 and 4. The product then passes to heater 30 and then to centrifugal separator 33. The substantially concentrated milk fat passes to pasteur'ser 38 preferably of the subatmospheric pressure type and then to one of the standardizing vats 42. 43. 44 which can be provided with standardizing ingredients from container 55. After standardizing and testing the product parses to churn 64 into which a predetermined quantity of gas may be introduced, and then to a crystallizing chamber 68 and finally through a texturating device 72 and packaging device 74. The prechurn 26 and the churn 64 may take the same form and may consist of a processing chamber 93, Fig. 3, surrounded by concentric heat exchange jackets 94 and 95. The product together with a controlled supply of gas enters through pipe 92 and then traverses the prechurn being agitated in its passage by elements 109 and 110, the walls being kept clear by scrap'ng blades 108. The product then passes out through spring loaded valve 105 which may be adjusted for varying pressures. An alternative type of prechurn consists of an inner liner 113. Fig. 4, supported by ribs 115 within jacket 114 so as to form a heat exchange system. An agitator having a plurality of blades 118 rotates on shaft 119 which is supported upon pivot 121.

Title: Improvements in and relating to sound reproducing apparatus
Inventor: GUEST LAWRENCE VINCENT
IPC: G11B17/16
Filed: 1956-08-14
Abstract: 810,599. Magazine gramophones. BIRMINGHAM SOUND REPRODUCERS Ltd. Aug. 1, 1957 [Aug. 14, 1956], No. 24884/56. Addition to 766,048. Class 40 (2). A magazine gramophone of the centre spindle type in which the starting position of the pickup is set by a detent member which is struck by a record disc in falling from the magazine to the turntable. Construction.-A lever 38 is pivoted at 40 to a fixed support 20 and is biased by a spring 41 which tends to turn the top of the arm 39 toward the wall 36. An arm 42 is mounted on a pivot 43 and is biased by a spring 51 to turn in a clockwise direction as seen in Fig. 2. Projecting from the arm is a stud 46 on which is freely mounted a detent member 47, the top surface 48 of which engages a lug 49 projecting from the arm 42. The lever 38 extends beneath the baseboard and engages a locator member 24, rigidly mounted on vertical spindle 18, rotation of which moves the pickup arm in the horizontal plane. Operation.-The normal position of the arm 42 is when it has rotated clockwise until the stud 46 bears against the arm 39 which is then held in the position shown in Fig. 3, so that the locator 24 turns until the step 27 engages the lever 38. In this condition the pick-up will be positioned to play a 7 inch record. When a 10 inch record is released from the magazine, the detent 47 is struck by the edge of the record and causes the arm 42 to pivot about the pin 43. The lever 38 rotates due to the action of the spring 41 until further movement is prevented by the turned over end of the lever striking the face 45 of the lever 42. In this position the lower end of the lever 38 engages the step 26 of the locator 24 and the pick-up is positioned to play a 10 inch record. A 12 inch record released from the magazine strikes the detent 47 which rotates with the arm 42 so that the lever 38 is free to move until the end 39 engages the wall 36. In this position the lower end of the lever 38 engages the step 25 of the locator 24 and the pick-up is positioned to play a 12 inch record. After each positioning operation a pin 56, driven by the automatic mechanism of the apparatus, engages the lower end of the lever 38 and returns it to its original position, thus releasing the pick-up arm from the restraint imposed by the engagement of the lower end of the lever with the locator 24. Specification 810,598 is referred to.
