Patent GB-652726-A (GB)
Title: A process for the production of aldehydes and alcohols
IPC: C07C27/22
Filed: 1948-12-13
Abstract: Aldehydes are obtained from the product of treating hydrocarbons having at least one olefinic double bond with a gascontaining carbon monoxide and hydrogen at elevated temperature and pressure in the presence of a cobalt catalyst, the volatile cobalt compounds in the synthesis product being decomposed and the aldehydes subsequently recovered by steam distillation.  Volatile cobalt compounds are decomposed in known manner, e.g. by treatment at elevated temperature with a gas containing less carbon monoxide than corresponds with the decomposition tension of the cobalt carboxyl compounds at the temperature employed particularly hydrogen or gases rich in hydrogen, nitrogen, steam or hydrocarbons.  The decomposition of the cobalt compounds is apparently necessary since steam distillation in their presence leads to various side reactions, thus reducing the yield of aldehydes and cobalt is deposited on the apparatus.  The aldehydes obtained may be hydrogenated to alcohols.  In an example the products obtained from an oxo-synthesis using 1-hexene, 1-heptene and 1-octene are first treated with hydrogen for an hour at 150 DEG  C. and 40-50 atmos. and then steam distilled, the aldehydes obtained being purified by a vacuum distillation of the steam distillate in a nitrogen atmosphere.  Tables showing the yields of recovered aldehydes are given.

Title: Improvements in or relating to trimming mechanism for cigar-making machines
IPC: A24C1/22
Filed: 1931-11-24
Abstract: 388,504. Cigar -making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Nov. 24, 1931, No. 32532. [Class 130.] In mechanism for trimming the ends of a cigar, the ledger plate for use in trimming the pointed end is moved axially of the cigar so that an aperture in the plate engages over the cigar tip until it reaches a definite diameter of the pointed end, at which trimming then takes place. The trimming - device for the other end is moved simultaneously with the ledger plate so as to ensure that the finished cigars shall be of equal length. The cigar C is discharged from the re-rolling drum 11 on to fingers 22 as shown in Fig. 1, and the pointed end is engaged by an aperture in the ledger plate 23 carried by a shaft 14, which is moved axially from the dotted position by an arm 35 connected by a rod 37 to the trimming-device for the other end. The latter comprises cutters 54, 55 pivoted at 51 to a forked member 42, which is moved about a pivot 43 from the dotted to the full-line position simultaneously with the movement of the ledger plate 23. The cigar is then gripped by a further finger 20 engaging its upper side and the ends trimmed. The cutter for the pointed end is actuated by a pin 34 on the drum 11 engaging an extension 32 of the blade. The oscillation of the members 35, 42 is effected by a cam 62, lever 59, and rod 38 connected by a ball joint 47 to an angle lever 46 attached at 45 to the member 42. The first downward movement of the rod 38 rocks the member 42 until a screw 49 thereon engages a stop 50. This brings the member 42, and through the rod 37 also the arm 35, to the full-line positions. Further downward movement of the rod 38 then swings the angle lever 46 about its connection 45, thus moving a pin 48 on the lever 46 in slotted extensions 56, 57 of the cutters 54, 55, which thus trim that end of the cigar. The cigar is then released by the fingers and discharged down the guide 17 at the left-hand side of Fig. 2.

Abstract: 762,499. Selective signalling by counting impulses. BRITISH TABULATING MACHINE CO., Ltd. Oct. 22, 1954 [Nov. 30, 1953], No. 33174/53. Class 40 (1). [Also in Group XL (b)] A shaft, e.g. of a weighing machine, signals its position by sending impulses to a counter which is stepped in one direction for clockwise and in the other for counter-clockwise rotation of the shaft. Discrimination between the two directions is obtained by causing the shaft to generate two sets of impulses in quadrature, deriving from one set two trains of impulses corresponding respectively to dark-to-light and light-to-dark transitions and rendering one or other train effective to control a trigger-circuit in accordance with the position of its impulses in relation to the impulses of the other set. As shown, the shaft carries a disc with two rings of alternate opaque and transparent portions cooperating with a lamp and with photo-cells 1, 2 arranged on a radius. It will be seen that when the disc rotates clockwise, the light-to-dark transitions of cell 1 take place with cell 2 light and conversely, when the disc moves counterclockwise, the dark-to-light transitions. The same effect can be produced with a single obturating ring and the photo-cells staggered. The counter is a set of polycathode discharge tubes. Discriminating arrangement. Each lightto-dark transition of cell 1 is made to produce a short + impulse in line 17 and each dark-tolight transition a short + impulse in line 18. Each transition either way of cell 2 produces an impulse in line 19 and these impulses control a bi-stable circuit 5 so that it is in one state while cell 2 is light and opens gates 6 and 7 and in the other when cell 2 is dark. Accordingly, with gates 6, 7 open, impulses reach the trigger circuit 8 via line 20 or line 21 according as the rotation is clockwise or counter-clockwise. Circuit 8 determines whether gate 9 or gate 10 shall be open in readiness for an impulse from 5 at each light-to-dark transition of cell 2. An impulse is thus sent for each pair of opaque and transparent scale marks to line 24 for clockwise and to line 25 for counter-clockwise rotation. Counter circuit. Impulses on 24 and 25 operate the polycathode units counter 53 in one direction or the other in known manner. When the discharge passes to electrode 0, the lefthand half of a valve pair 50 conducts and the right-hand half is cut off. A negative impulse is passed on to the left-hand half of a pair 52 to to cause the right-hand half to conduct provided that the equipment is set for adding as determined by the bias voltage on 22 furnished by the trigger 8. An " add " impulse is then given to the tens polycathode tube 54. If the equipment is subtracting, the cessation of the discharge to electrode 0 changes over the pair 50 and the resulting impulse causes a discharge in the right-hand half of 51 provided that the trigger 8 is biasing it to " subtract". A " subtract "-impulse is then given to the tens tube.
