Title: Improved process for hydrogenating edible oils
IPC: C11C3/12
Filed: 1950-05-25
Abstract: <PICT:0673273/III/1> In the continuous catalytic hydrogenation of edible oils under elevated temperature and pressure, the hydrogen is added in excess of that theoretically required and the hydrogenated oil is passed whilst still hot and out of contact with the outside atmosphere to a pressure release zone where it is subjected to heat and subatmospheric pressure to liberate free hydrogen and odoriferous materials.  As shown, the oil-catalyst mixture, deaerated if desired, is passed through line 15 along with hydrogen from line 16 into hydrogenator 18 which is maintained at, for example, 300 DEG F. and 20-75 p.s.i. pressure.  The hydrogenated mixture is passed through line 23 to enclosed filters 24 where the catalyst is removed and then through valve-controlled lines 25, 26 to degassing tank 28 which is heated to, for example, 400 DEG F. by coil 29 and maintained under a pressure of, for example, below 50 m.m. Hg, by barometric condenser 32.  Oil from tank 28 is passed in countercurrent flow to steam in a deodorizing column 34 which is also maintained under reduced pressure and on being withdrawn the oil is passed through coil 40 of a steam generator, the steam so produced being passed through a superheater 42 before entry to the column 34.  Oil from coil 40 is passed through a second pair of enclosed filters 48, then through valve-controlled lines 49, 50 into container 52.  As alternative features, the hydrogenated mixture may be passed directly to deodorizing tank 34 and one pair of filters, either 24 or 48, may be omitted.

Patent GB-641853-A (GB)
Title: Improvements relating to electric toasters
IPC: A47J37/08
Filed: 1948-05-14
Abstract: 641,853. Toasters. HOOVER, Ltd. May 14, 1948, No. 13305. Convention date, May 17, L947. [Class 28(i)] Crisp or moist toast is obtained by uncovering or covering, like a ventilator, the bread receiving slot of an electric toaster, such opening or closing being arranged to vary the timing of an automatic timing device. The mechanism for toasting and timing with automatic release is generally as described in Specification 640,072, but the toasting period is varied by the movement of the slot cover to open or closed position which moves the timing heater 70 further away from or nearer to the bimetallic control strip 58. Further, the bread carriers 25 when released from the primary holding down latch 37 by the timer, are still held down by the secondary latch 91 until it is released by the hand opening of the slot. When the slots 12 are not covered by the covers 71, toasting is started by pushing down the handle 30 coupled to the bread carriers 25 until they are latched by the primary latch 37. The main switch is thus closed to energize both the toasting heaters and the timing auxiliary heater 70 which heats up the bi-metallic control 58. A cam 82 on the slot cover pivot 73 rides on the top end of a top-to-bottom connecting rod 81 whereby the bottom end, by being coupled to a pivoting lug 83, allows the timing heater to take the position furthest from the bi-metal 58, i.e., to the left, thus giving a longer toasting period to make dry crisp toast. When the bi-metal 58 eventually springs over to its dotted line position it allows rod 46 to move to the left, thereby opening the micro-switch 118 and so de-energize the timing heater 70. Thereafter the bi-metal cools and springs back to full line position so that 57 strikes the rod 56, which unlatches the latch 37, thus releasing the bread carrier 25-26. The length of this toasting period is set as required by the knob 120 of rheostat 119. With the slots uncovered the cam 82 holds open the secondary latch 91-93 since the bottom end of the rod 81 holds pressed down the lever 87 (pivoting about 88), the upturned end 89 of which holds out the hook 93 of the latch 91. Thereby the bread carriers are raised by their springs 33 out of toasting position on timed release of the latch 37 only. For moist toast the slot covers are pressed down by hand about their pivots 73 to close the slots 12 after the bread has been lowered into toasting position. The cam 82 on the pivot 73 is thereby moved to such position that the bottom end 86 of the rod 81 rises so that the lug 83 pivots the timing heater 70 nearer to the bi-metal 58, thereby shortening the toasting period. The bottom end 86 also clears the lever 87 so that in this case the latch 91-93 can assume the holding down position, to be released by hand opening of the slots to remove the bread.

Title: Improvements in or relating to pyrophoric lighters
IPC: F23Q2/46
Filed: 1949-05-20
Abstract: 673,080. Pyrophoric lighters. LEVENE, M. M. May 9, 1950 [May 20, 1949; Jan. 6, 1950], No. 13593/49. Class 75(iii) A pyrophoric lighter comprises means for causing both the flint and a spring- pressed flint-follower which is longitudinally movable in a freely rotatable flint holder to rotate with the latter. A horizontal flint tube 7 is provided with two internal, longitudinal slots or grooves 10 engaged by projections 13 of a spring- urged flint-follower 12, which makes a straight-line contact with the flint 4. Forward movement of the follower 12 is limited by the engagement of the projections 13 with the ends of the grooves 10. In an alternative arrangement the grooves 10 are dispensed with, the flint tube and follower being the same polygonal shape in cross section. The forward end of the flint spring 14 is secured to the flint follower while the rear end pushes on a plug 16 fixed in a slidable sleeve 18, the flanged rear face 17 of which is normally held flush with the rear of the casing 1 by the engagement of a projection 22 on a spring-controlled pushrod 21 with an annular groove 23 in the sleeve 18. The forward end of the sleeve 18 engages over the rear of the flint tube 7. To insert a new flint the rod 21 is pushed in whereupon the spring 14 pushes out the flange 17 so that the flint follower assembly can be withdrawn to expose a flint-inserting aperture 11 in the flint tube 7. In a modification the flint tube extends to the rear of the casing, and has an internal longitudinal groove in which a projection 13, Fig. 7, on the flint-follower 12, engages. The groove communicates at the rear end of the tube with a slot having a lateral extension in which a pin 33, on an end plug 32 engages. The pin 33 is set further round than the projection 13 so that a slight torque in the spring holds the pin in said lateral extensions. The whole assembly shown in Fig. 7, is withdrawn from the flint tube for insertion of a new flint into the rear of the tube. A spring-pressed pawl pivoted in the cap 2 of the lighter engages a ratchet wheel 9 at the forward end of the flint tube, the arrangement being such that the latter, together with the flint follower 12 and flint 4, is rotated either as the cap is raised, or as the cap is lowered. Alternatively the flint tube may be connected by gearing to the thumb wheel 6 or 626,585 and 672,310 are referred to in the second Provisional Specification.

Title: Improvements in the manufacture and production of vinyl chloride
IPC: C07C17/08
Filed: 1937-05-20
Abstract: Vinyl chloride is prepared by leading acetylene and hydrogen chloride at elevated temperature over active carbon supplied continuously or periodically with mercury, e.g. by adding drops of mercury to the carbon or by passing the gases through heated mercury before contact with the carbon.  Impure acetylene, such as that prepared by thermal or electrical treatment of hydrocarbons, may be employed.  Mercury or its salts, particularly the chlorides, may originally be present in the carbon.  In an example, electric arc acetylene is led with hydrogen chloride through mercury at 100 DEG  C. and then through active carbon at 130 DEG  C.; the vinyl chloride is separated by cooling and absorption on active carbon.
