Patent GB-455264-A (GB)
Title: Process for the manufacture of esters of polycyclic alcohols
IPC: C07J1/00
Filed: 1935-04-08
Abstract: The process described in the parent Specification which comprises the reduction of esters of the male sex hormone to produce ester-alcohols is modified so as to produce di-esters, which modification consists in subjecting the ester-alcohols of the cyclopentanopolyhydrophenanthrene series of the formula C19H32O2 to the action of acylating agents.  The acylating agent may contain an acyl group different from that of the mono ester and so lead to the formation of a mixed ester.  In examples: (1) androstandiol-monoacetate-(3) is treated with benzoyl chloride in pyridine solution, poured on to ice and extracted with ether. Benzoyl chloride and pyridine is removed by sulphuric acid and the androstandiol-acetate-(3)-benzoate-(17) recrystallized from methanol; (2) trans-androstandiol-monoacetate-(3) is converted in a similar manner into trans - androstandiol-acetate-(3)-benzoate-(17); (3) androstandiol-monoacetate-(3) is treated with o-nitro-benzoyl chloride, and the product worked up as described in example (1) to yield androstandiol-acetate-(3)-o-nitro-benzoate-(17).

Abstract: 1,084,891. Irradiation apparatus. SULZER BROTHERS Ltd. March 29, 1965 [April 14, 1964], No. 13279/65. Heading H5R. [Also in Division B8] A method of irradiation of units of material involves passing the units into the irradiation chamber on a conveyer and transferring them from this on to a closed-loop conveyer system which carries the units around the irradiation source and comprises at least two closed loops each located in a single plane of conveyance, the planes being parallel to one another. In one system (Fig. 1) in which the conveyer 8 carrying units into the chamber is generally horizontal at the region of transfer of the units to the closed loop system 13, the two loops of which are arranged side-by-side and driven to move together, an unirradiated unit is transferred to the first closed loop of the generally vertical chain conveyer 13 and undergoes a first irradiation by conveyance around this loop. The unit is then returned to the horizontal conveyer 8, moved into alignment with the second closed loop and transferred on to this for a second irradiation, after which it is returned to the conveyer 8 for removal. In an alternative system, the closed loop conveyer could be horizontal and the supply and removal system be vertical. The source is a slab-type arrangement of rods of Co 60, and is introduced into the chamber 1 through a door 3. It can be lowered into a pit (5, Fig. 2, not shown) located below the chamber, where it is shielded by a top shield (6), so that operatives entering the chamber via door (7) are protected. A spy hole (4a) is provided. The material for irradiation may be bottles of cat gut in large boxes. The conveyer 8 may be one of a number of types, e.g. roller, chain-driven train &c. The entrance and exit sections of a roller conveyer are inclined, and the horizontal section adjacent the transfer means includes a pusher to advance the units by the length of one unit at each operation. A number of different transfer mechanisms are described (Figs. 5-7, not shown) to lift packages from the horizontal section on to the vertical chain conveyer (see Division B8).

Abstract: 769,812. Sheet-delivery apparatus. LEVEY CO., Inc., F. H. May 9, 1955 [Nov. 24, 1954], No. 13353/55. Class 100(1) Signatures, stripped from the drum 2 of a cutting and folding machine are fed by laps 4, 5, to 'a spiral conveyer 7. Each spiral, of which there are two, is rotatably supported by a shaft 8 driven by gear 10, 11, Figs. 1 and 2. The spirals forward the signatures along a table 12 to an endless conveyer 13 supported by a table 19 where the signatures are stacked against an angle-iron 23. Side guides 24 are provided for correctly aligning the signatures. The belts 4, 5 serve to slow down the signatures as they are delivered to the spirals 7 but where no such belts are provided air may be blown along the shaft 8 against each signature as it is delivered to the spirals to prevent damage to the edge of the signature. In a further embodiment the spirals are made hollow and connected to a source of air which is blown through nozzles in the ends of the spirals against the stack 22 thus preventing excessive rubbing of the spirals on the stack. As the stack 22 is built up a portion 29 thereof may be moved to the opposite end of the cnnveyer 13 on to a receiving cradle 25 hinged to the table 19 at 26 so that the cradle may be moved through 90 degrees to facilitate further handling of the signatures. Where the signatures are delivered to the spiral with their longer dimension vertically disposed, Figs. 6 and 7, they are guided along the table 12 to a ring 38 of an inner diameter substantially equal to the diagonal dimension of the signatures. The ring 38 is preferably knurled on its inner end and rotated at a speed such that it turns through 90 degrees in the time it takes for a signature to pass through it. Each signature is thus rotated so that its longer side is horizontal and is delivered by the spiral on to a table 12a and thence to the conveyers 13.
