Patent GB-723785-A (GB)
Title: Improvements in or relating to hydroforming
IPC: C10G35/14
Filed: 1951-10-23
Abstract: A naphthenic naphtha and an olefinic naphtha are fed with hydrogen to a hydroforming zone maintained at a pressure of 100-400 p.s.i.g., and a hydroforming temperature, generally 875-950 DEG  F., and containing a powdered hydroforming catalyst which is maintained as a dense fluidized bed by the upward flow of reactants, a product of increased aromaticity and octane rating being recovered.  The naphtha feed should be preheated to below 1050 DEG , preferably about 950 DEG  F., while the hydrogen-containing recycle gas may be at 1100-1400, preferably 1150 DEG  C.  The two types of naphtha may be fed separately at spaced points so that an olefinic naphtha boiling, e.g. below 180 DEG  F., traverses a shorter path through the hydroforming zone.  The olefinic naphtha may be the product of thermal cracking of heavy residues or heavy or light naphtha from catalytic cracking of gas oils.  It is desulphurized during the processing.  Suitable catalysts are Group 6 metal oxides or platinum group metals on high surface spacing agents, e.g. molybdena or chromia or calcium or cobalt molybdate on zinc spinel, platinum or palladium on alumina with or without hydrogen fluoride.  Other supports are magnesia, silica or zirconia.  The catalyst level may be varied to alter the severity of processing.  The preferred contact time is 40-300 secs. In examples, 3 vols. of a virgin naphtha of B.R. 185-345 DEG  C. are fed with 1 vol. of catalytically cracked naphtha B.R. 327-423 DEG F., using molybdena on alumina; using a cracked naphtha boiling up to 200 DEG  F., this is fed nearer the top of the reactor so that it traverses not more than 1/2 , preferably 1/4 of the catalyst bed.

Patent GB-366879-A (GB)
Title: Improvements in cop winding apparatus
IPC: B65H54/14
Filed: 1931-09-03
Abstract: 366,879. Winding yarn on cops &c. MASCHINENFABRIK SCHWEITER AKT.- GES., Horgen, Switzerland. Sept. 3, 1931, No. 24784. Convention date, Sept. 4, 1930. [Class 120 (ii).] In cop-winding apparatus having a thread guide adjustable on a reciprocating camactuated rod and advanced by a friction wheel or feeler adjustable on a screw, the feeler and screw are carried by a rocking carrier moved, during movement of the feeler, to shift a lever which reciprocates the thread guide rod and vary its point of engagement with an actuating lever rocked by the cam. A heart-shaped cam groove 11 in the face of a continuously rotating disc 2 engages a pin 9 on a lever 8 pivoted at one end to a boss 6 on a casing 1. The lever is of U-section to engage the end 17 of a lever 16 slidably mounted on a shaft 12, the rotation which it controls by means of a rod 15 passing through it and secured at its ends to arms 13, 14 keyed to the shaft. The arm 14 forms part of a bell-crank lever the longer arm 14<1> of which reciprocates a guide rod 20 carrying the thread guide 43 and the amplitude of the movement is determined by the position of the end 17 of the lever 16 in the lever 8. This is controlled by an arm 21 engaging a notch 22 in the lever 16 and keyed at its other end to a shaft 24 on which are also keyed arms 25, 26 of a rocking carrier. Slidably mounted in the arms 25, 26 is a screwed rod 27 adapted to be reciprocated, over a small distance, in the opposite sense to the guide rod 20, by a rod 30 secured to it by a quadrant 29 pivoted on the shaft 24 and engaging a slot in the screwed rod, the rod 30 being actuated through a tappet 31 by a cam &c. 34 integral with the disc 2. A friction wheel 36 having a smooth bore is operatively connected to the screwed rod 27 by a tongue 39 engaging the thread thereon and when the reciprocation thereof brings the wheel into contact with the cop being wound, the wheel is rotated and traversed along the rod. This movement brings the tongue 39 into the cored end of a sleeve 49 and the wheel 36 displaces the sleeve and a bracket 40 secured to it and movable along the shaft 24. Thereupon, a lug 42 on the bracket 40 encounters the thread guide 43 and displaces it along the rod 20. Simultaneously, a roller 45 on an arm 44 on the bracket 40 rolls along a templet 46 and the shape of the templet, by determining the position of the carrier comprising the screwed rod 27, arms 25, 26 and shaft 24, determines the position of the lever 16 relatively to the lever 8 and the amplitude of the reciprocation of the guide rod 20. Different shapes of templets are used to obtain different forms of packages.

Title: Improvements in or relating to coin freed vending machines
IPC: G07F11/04
Filed: 1928-08-29
Abstract: 322,213. Avery, Ltd., W. & T., and Bradley, L. C. Aug. 29, 1928. Delivery of articles stored in piles.-In coin operated mechanism for vending towels and flat articles, the column of articles is carried by horizontally disposed pins capable of being manually rotated through an angle of 90‹ to effect the release of an article after the insertion of a coin. The articles 6 are interposed between cards 7 and arranged alternately lengthwise and crosswise, the lowest resting on the rotatable pins 8a. A weighted plate 12 guided by the rods 8 rests on the top of the articles and facilitates the feeding motion. A catch 13 engages in a slot in the top of the casing to hold the plate 12 when the machine is being refilled. On closing the door, a projection on the plate 12 disengages the catch 13 and causes the plate 12 to fall on to the top of the articles. Coin actoin.-A coin inserted in the shoot 21 tilts the diverting plate 41 to close the coin and enters one of a pair of pockets 17b in the drum 17. The drum is normally locked against rotation by the engagement of one of the two pins 17<c> with a notch in the lever 24. On moving the handle 19, the coin 22, which projects above the periphery of the drum 17 engages the pin 24<a>, thereby depressing the lever 24 against the action of the spring 25 and freeing the drum. A spring loaded pawl 26 prevents rotation of the wheel 19 in a reverse direction. Coin-discharging mechanism.-The drum 17 to which the rod is attached is free to rotate through 180‹ before the other pin 17<c> engages the notch in the lever 24. The coin is then free to fall out of the pocket into the cash box 40, and the other pocket 17<b> is below the coin shoot 21. The rotation of the drum 17 through the rod 16, bell crank 15, and interconnected cranks and links, effects the rotation of the rods 8 through an angle of 90‹ whereby the pins 8<a> are turned to release a towel which is delivered into a shoot. Retturning coin.-The pins 17<c> are also adapted, during the rotation of the drum 17, to depress the spring restrained lever 27 to actuate the rod 29 which is attached to a pivoted side 30 of the coin shoot. The opening of the side 30 effects a clearance of the coin shoot and ejects any foreign matter into a return pan. Coin-slit closing-devices.-When the apparatus' is empty, the projection 12<c> on the weighted plate 12, contacts with the trip lever 34 causing the rod 35 to rise, and thus move the cover plate 36<b> which closes the coin shoot. " Empty " notices, displaying.-The lever 37 is operated by the rod 35 to bring the word " Empty " on the plate 37<a> into view simultaneously with the closing of the coin shoot.
