Title: A method of reducing the amount of pitch formed at the distillation of tall oil
Filed: 1953-04-21
Abstract: Tall oil is distilled under reduced pressure in the presence of a current of superheated steam, the amount of steam introduced into the still being 20 to 300 per cent by weight of the amount of the tall oil feed.  The use of a far larger proportion of superheated steam than in previous methods reduces the amount of residual pitch.  Tall oil (acid number 172; unsaponifiable matter 10.3 per cent), preheated for about 15 minutes in an electrical heater, was introduced into the side of a fractionating column (200 cms. long X 5 cms. diameter) filled with porcelain saddles; the oil being supplied at a point two-thirds the distance up the column from the base.  The rate of tall oil feed was 200 grm. per hour.  The column was mounted on a boiling vessel, both being electrically heated, and superheated steam at 225 DEG  C. was introduced into the boiling vessel at the rate of 100 grm. per hour.  The column was surmounted by an air-cooled dephlegmator, the outlet of which was connected to water-cooled coolers and distillate-receivers.  The pressure at the top of the column was maintained at 20 mm./Hg., and the distillation temperature was 260 DEG  C.  The amount of residual pitch was 13.6 per cent based on the feed.  The acid number of the distillate was 177; and the unsaponifiable matter thereof was 7.3 per cent.

Abstract: 716,151. Machinery safety devices. TAYLOR & CHALLEN, Ltd. May 26, 1953 [May 6, 1952], No. 11375/52. Class 80 (4) [Also in Group XXXIV] In a press which is driven by a crankshaft 10 connected to a flywheel by a pedal- or leveroperated clutch (not shown) and which has a guard (not shown) which is held closed on the down stroke of the ram but may be opened on the up stroke, the crankshaft is automatically braked and stopped if it should overrun the top dead centre position or should drop back, i.e., reverse, therefrom. A bar 24 connected at one end to the guard is linked at the other end to articulated brake shoes 11, 12 an the crankshaft, and in the guard-open position shown is lowered so that an abutment 26 thereon lies in the path of a lug 27 on a spring-loaded bellcrank controlled by a cam 31 on the crankshaft. Should the crankshaft overrun the top dead centre position ( at which it normally comes to rest) while the guard is open the cam moves the bar 24 to apply the brake assembly, which is held against angular movement by a fixed peg 22. The bell crank, which is pivoted at 29, engages the cam through a roller 30 on whose axis is pivoted a pawl 35 biased to engage a disc on the crankshaft, the disc having a tooth 35' so that if the crankshaft drops back while the guard is open the pawl and bell crank are rocked to apply the brake as above. The pawl is coupled to the bar 24 by a link having pin- and-slot connections so that in the guard-closed position the pawl is lifted to clear the tooth 35<SP>1</SP> during normal operation. The cam subtends an angle of less than 180 degrees and is normally operative on the down stroke to hold the lug 27 beneath the abutment 26 and lock the bar 24 in the raised position to prevent opening of the guard. The crankshaft may thus be freely moved manually with the guard open. In a modification the tooth 35<SP>1</SP> and pawl 35 are replaced by a pawl pivoted on a disc on the crankshaft and co-operating directly with the roller 30, the pawl comprising a weighted lever which is centrifugally withdrawn in normal operation.

Abstract: 734,717. Latches. PARKES& SONS, Ltd., J., BUTTER, F. J., and ORDIDGE, E. F. April 1, 1954 [April 25, 1953], No. 11493/53. Class 44. In a door latch, a spring-loaded latch bolt has a longitudinal guideway on the side of the bolt head 10 remote from the striking face in which is mounted a spring-loaded auxiliary slide 22 that is held back by an abutment projecting into the recess 29 in a striking plate 30 when the bolt head enters the recess the abutment being of such size and shape as to allow the bolt head to pass it. When held back the slide 22 permits the nose 27 of an arm 28 to move into the rear of the bolt head 10 to secure the bolt in the shot position. The auxiliary slide 22 is dovetailed into a channel in the bolt head 10 and its rear portion 23 comprises two lugs which slidably embrace the wide central portion 16 of the bolt lath 11. By sliding the auxiliary slide 22 to the narrow portion 17 of the lath it can be completely removed from the bolt. In the condition shown the latch is out of engagement with the striking plate 30 and the rear portion 23 of the auxiliary slide prevents the nose 27 from locking the bolt. When the bolt is moved inwards by the striking plate 30 the rear of the bolt head forces the auxiliary slide 22 inwards also, but whereas the bolt is free to spring into the recess of the striking plate the projection 31 engages the leading end 21 of the auxiliary slide and holds it in the withdrawn position which permits the nose 27 to engage the rear of the bolt head 10 to secure it. To release the latch the nose 27 is deflected downwards by the camming action of the follower 13 on the arm 33 of a bell crank lever on which the nose 27 depends ; at the same time a pin 15 on the follower engages the bolt and withdraws it from the recess in the striking plate.

[Class 40 (i).] An electric indicating device adapted, for example, for indicating successive positions of a float 1, Fig. 1, in a tank containing liquid comprises a contact piece 2 adapted to engage a set of contacts 4, each connected to an electromagnet located near to a magnetized needle 6. The magnets are polarized by windings 11 so that the magnetization resulting from the energization of the windings is of opposite polarity to, but less than, that due to the energization of the coils connected to the contacts 4. The needle 6 may be a permanent magnet or may be magnetized by a weak current through a coil located around the pivotal axes of the needle. In the construction shown in Fig. 3, a source of current 3 is connected to two contact pieces 2, 2a, which are insulated from each other and are adapted to engage contacts 4. Each contact is connected to two diametrically opposite electromagnets such as 5, 15 which are arranged round a star-shaped magnetized member 6. The arrangement is such that the member 6 rotates at half the rate of rotation of the shaft 7 carrying the contact pieces 2, 2a. The number of electromagnets 5, 15 may be another multiple, or a submultiple, of the number of contacts 4. To nullify the effects of self-induction a direct current generator may be mechanically connected to the shaft 7 and arranged in series with the source of current 3 to provide additional voltage proportional to the speed of the shaft 7. Alternatively, a high resistance may be inserted in the circuit through the source 3. The construction shown in Fig. 3 may be modified for use as a speed-indicator, the member 6 being replaced by a squirrel-cage magnetic member 17, Fig. 5, connected to a spiral spring 18. The shaft of the member 17 carries a pointer co-operating with a graduated scale 20.
