Title: Improvements in or relating to synthesis of lysergic acid and homologues thereof
Filed: 1954-10-25
Abstract: Lysergic acid or a homologue thereof is prepared from a compound of the formula <FORM:0774984/IV(b)/1> by treatment with a dehydrogenation catalyst such as deactivated Raney nickel, R1 being C1-C8 alkyl, R2 being H or RCO (where R is C1-C8 alkyl, monocyclic aryl or monocyclic aralkyl with 1-8 carbon atoms in the side chain) and R3 being CN or COOH, the acyl and nitrile groups being first hydrolysed with a strong base.  The product is lysergic acid if R1 is methyl.  The Raney nickel can be deactivated by heating with xylene, toluene, acetone, cyclohexanone or other liquid which serves to remove the adsorbed hydrogen.  The yield is improved by adding hydrogen acceptors such as sodium arsenate, halides, maleates or cinnamates.  The starting materials are described in Specifications 774,990, 774,991 and 774,992.  Examples are given of the production of dl-lysergic acid from compounds (1) R3=carbomethoxy (hydrolysed), R2=H; (2) R3=cyano, R2=acetyl; and (3) R3=carboxyl, R2=H.  Other starting materials are mentioned in which R1 is ethyl, propyl or heptyl and R3 is carboxy, carbomethoxy, carbethoxy or carbopropoxy. It is stated that R2 may also be toluyl, valeryl or heptanoyl.  Other suitable dehydrogenating catalysts are platinum black and palladium on carbon or alumina.

Title: Improvements in hydraulic presses
IPC: B30B15/00
Filed: 1950-12-22
Abstract: 696,835. Hydraulic presses. TURNER TANNING MACHINERY CO., Ltd., and HALL, C. Nov. 28, 1951 [Dec. 22, 1950], No. 31207/50. Class 69(ii) A hydraulic press assembly comprising a main ram or piston and an auxiliary ram or piston displaceable in corresponding cylinders to move a platen of the press with a rapid approach stroke and a slower and more powerful pressure stroke is characterized by the fact that the main ram or piston is formed at its inner end so as to co-operate with hydraulic fluid in its cylinder and function as a dashpot or equivalent for damping the pressopening movement. A leather ironing and embossing machine comprises a fixed frame 1 supporting an upper fixed anvil 2, Fig. 1, and a platen 3 having a part-spherical self-centering bearing 4 seated in the upper end of a main ram 6. The cylinder 7 in which it slides has its base end centrally bored to receive slidably an auxiliary ram 8 having at its upper end a valve 9 with lateral ports and a slidable valve body. The lower end of the ram 8 moves in an auxiliary cylinder 10 depending from the underside of the main cylinder 7 and connected to an oil pump and reservoir, as described in Specification 539,160. A return valve in a casing 11 communicates with the cylinder 7 through a port 14 as described in Specification 539,159. To provide the dashpot action the ram 6 is formed with a shallow cylindrical depression 15 at its lower face leaving an outer annular depending rim 16 which moves opposite a channel 17 of curved cross-section around a central boss 18 at the bottom of the cylinder. The ram 6 is dimensioned with respect to the main cylinder 7 and its port 14 so that when the ram is in its lowermost working position the orifice 14 is only partly shut off. In addition, to give an increased passageway for oil beneath the ram 6 to the port 14 the internal surface of the. main cylinder 7 has a narrow annular semi-circular groove 19, Fig. 2, whilst the lower outer edge of the piston rim is bevelled off at 20 leaving, in the lowest position of the ram, a small clearance between this rim and the bottom edge of groove 19 which permits exertion of the dashpot effect but eliminates " cavitation " when the ram is moved upwards again. The sleeve of the valve 9 is applied against the centre of the depression 15.

Patent GB-1419730-A (GB)
Title: Landing and approach system scanrate station identification
IPC: G01S1/10
Filed: 1974-07-15
Abstract: 1419730 Radio navigation SINGER CO 15 July 1974 31309/74 Heading H4D In a microwave landing system of the type wherein a beam is sequentially switched into left localizer, upper glideslope, right localizer, and lower glideslope positions, for reception by an airborne receiver, a Morse code identification of the ground station is provided by switching the beam at a first frequency to represent a mark, and at a second frequency to represent a space. Means are provided in the airborne receiver to decode the first frequency and to give a corresponding audio tone output. As described, an oscillator 11, Fig. 1, of frequency 805 Hz is coupled to first inputs of two AND gates 13, 15. The second inputs to the AND gates are obtained from a photo-detector 23, which gives an output signal when illuminated by a lamp 21. A code wheel 17, driven by a motor 19, is interposed between the lamp 21 and the detector 23, and has alternate clear and opaque areas around its periphery, the former corresponding to marks, and the latter to spaces, of the ground station identification code. The second input to the AND gate 13 is coupled through an inverter 27 and hence that gate will be enabled for a space, whilst the gate 15 will be enabled for a mark. Output from the gate 13 is coupled through divide-by-six circuitry 29 to one input of an OR gate 31, and output from the gate 15 is coupled through divide-by-seven circuitry to the other input thereof. Output of the OR gate 31 is used for beam switching, and is at frequencies of 115 Hz for a mark and about 134 Hz for a space. In the airborne receiver, the second harmonic of the mark frequency is extracted from either the localizer or the glideslope mixer by means of a 230 Hz band-pass filter 37, Fig. 2A. The output of the filter 37 is coupled to a detector 39 and, provided it exceeds a reference voltage value, causes a tone generator 41 to give a signal to the pilot's headphones 43. Alternatively, the band-pass filter may simply be coupled to the headphones through a frequency tripler (Fig. 2B, not shown).

Title: Improvements in and relating to hanging files
IPC: B42F21/04
Filed: 1958-10-01
Abstract: 846,644. Filing papers; indexing. LAVOILLOTTE, M. Oct. 1, 1958 [Oct. 8, 1957], No. 31379/58. Classes 16 and 146(1). [Also in Group XXV] A hanging file assembly consists of the combination of a clip formed from a spring wire folded at its middle so as to form a U -bridge with very tight arms 1, 2 a second time at 3, 4 to form two further U's in parallel planes perpendicular to the plane of the U-bridge and a third time so that the free ends of the wire 7, 8 are bent into loops directed towards the U-bridge, with a file having one edge of at least one flap folded and fastened to form a seating capable of taking one arm of the clip. The file consists of a folder each flap 11 of which is folded at 12 to receive a suspension rod 21 having S-shaped ends co-operating with a pair of horizontal suspension rails 24 and arched at 25 to accommodate fasteners 26. The edges of the flaps are bent back on themselves at 14, 15 and fastened at 18 to form two seatings 16, 17. Thus two files may be united by inserting under the fold 16 or 17 of a flap of each file an arm of the clip, or by placing a flap of a file between the free arm 5 of the clip and the flap carrying its other arm. Alternatively the clip is used to close a given file instead of joining it concertina-wise with an adjacent file. The bridge 1, 2 of the clip may carry a label covered by a transparent sheath 9 together with one or more coloured sliders 10. Alternatively the flaps of the file may be profiled to have, in place of the vertical portion 15, a lower oblique portion inclined oppositely to the upper portion 14, so that a label may be sloped upwards and backwards, or upwards and forwards, according as the file is placed in the bottom or the top of a cabinet, respectively, to facilitate reading of the said label.

Abstract: 669,559. Cigarette-making machines. MOLINS, D. W., RUAU, F. F., and MOLINS MACHINE CO., Ltd. Dec. 29, 1949 [Dec. 3,1948], No. 31397/48. Class 130. In a continuous-rod cigarette-making machine wherein a continuous filler of tobacco fed by a conveyer 1 through a guide 2 forces mouthpiece plugs from successive bores or flutes in a rotating drum 3 and the resulting composite filler of aligned plugs 5 and tobacco lengths 4 is enclosed in a web 6 of cigarette paper, a finger 8 following the path 9 is moved behind each stub so as to overtake and accelerate any incorrectly positioned stubs when the filler is passing under a compression tongue 7 which presses it against the web 6. The tobacco filler passes through each bore in the drum 3, pushing a plug 5 before it, until a length 4 emerges, when the portion in the bore is cut off by rotation of the drum to bring the next bore carrying a plug into line with the filler. The tobacco left in the drum bores is forced out either by reciprocating plungers or by the insertion of fresh plugs. The aligned plugs and tobacco lengths pass through a guide 20 and beneath the tongue 7 having a slot 10 through which the finger 8, actuated from a crank 16, descends. Specification 669,557 is referred to.

Title: Improvements in printing presses
IPC: B41F3/20
Filed: 1934-11-01
Abstract: 436,995. Printing machines. COX, P. F., 5437, Kenmore Avenue, Chicago, U.S.A. Nov. 1, 1934, No. 31404. [Classes 100 (i) and 100 (ii)] In a printing-machine in which a plurality of impression cylinders are each given an orbital movement, and print in coaction with plane or curved printing-beds, the impression cylinders 35 are moved in a substantially circular path and preferably are spring- mounted in crossheads 34 mounted on a central shaft 32. The cylinders 35 receive sheets from gripper drums 3 rotated intermittently by Geneva-stop mechanism 4, 4a, 7, driven by sprocket gearing from the shaft 32, and after printing in conjunction with beds 19, 19a, 19b, the printed sheets are delivered also by gripper cylinders 61 actuated by Geneva-stop mechanism. The type beds are inked by rollers 36 carried in adjustable bearings 50 supported in carriages 51 mounted in sliding bearings in the crossheads on studs which permit the carriages to tilt. Vibrating rolls 54 distribute the ink on the rollers 36, and cam bearing plates 26 engage gudgeons on the rollers 36 so as to cause each pair of rollers to co-operate with the correct supply roller of the three rollers in fountains 56, with the correct distributing plate 27, 27a, 27b, and with the correct printing-bed. The plates 26 also raise the ink rollers out of contact with the feed and delivery drums. The fountain rollers are rotated intermittently by ratchet mechanism operated by a cam 37 rotating with the shaft 32. The plates 27, 27a, 27b are attached to an ink frame 20. The impression cylinders 35 are pressed outwards by springs 49 and are controlled by bearer plates 21 which keep the cylinders out of contact with the inking devices but permit the printing operation to take place normally. The impression may be thrown off by means of rails 81 which can be raised by pedal-operated levers 80, 83 to engage cylinder bearers 82. The cylinders are fitted with spring-controlled grippers which are raised to take the sheets from the feed drums 3 by means of cam levers operated by a fixed cam 46 The feed grippers 11 are controlled similarly and are operated by a lever 13 which is engaged by a roller 15 on the crosshead for opening the grippers 11 when the sheet is to be transferred to the impression cylinder. The printed sheets are taken by delivery grippers operated in a similar manner to the feed grippers, and the sheets are deposited on a table 66 supported on each side by a roller chain with a counterweight 67. The chains are carried over sprockets 69 on a shaft 70 geared by worm gearing to a ratchet 74 which is intermittently rotated by a pawl and lever 75 operated by an eccentric on the shaft 77 of the Geneva-stop mechanism which rotates the delivery drum. The cylinders 35 are rotated by gear wheels 92 engaging fixed racks 22, 23 at the sides of the printing- beds, and a curved rack 25 inside the ink frame 20.
