Patent GB-822197-A (GB)
Title: Improvements relating to the catalytic reforming of petroleum hydrocarbons
IPC: B01J37/02
Filed: 1956-09-13
Abstract: A catalyst for reforming hydrocarbons comprises a chromia-alumina catalyst containing a minor proportion of bismuth or a bismuth compound and may be promoted with an alkali metal oxide.  The catalyst preferably contains 5 to 25% chromia, 0.1 to 5% bismuth oxide and 0.1 to 5% potassium oxide, the balance being alumina.  In an example, 160 g. of 4-8 mesh B.S.S. granulated alumina was roasted for 2 hours at 550 DEG  C. and impregnated with a solution of 23 g. chromium trioxide, 4 g. potassium nitrate and 3.9 g. bismuth nitrate in 40 ml. of distilled water and 40 ml. of conc. nitric acid.  The solution was wholly absorbed and the catalyst dried at 120 DEG  C. for 15 hours and roasted at 550 DEG  C. for two hours.  The first Provisional Specification also refers to the use of chromia-alumina catalysts containing a minor proportion of bismuth, tin or antimony and a minor proportion of potassium, caesium or nibidium. Specification 820,403, [Group IV (b)], is referred to.ALSO:A feedstock comprising non-aromatic hydrocarbons is reformed at 450-580 DEG  C. and not more than 50 p.s.i.g. with a chromia-alumina catalyst containing a minor proportion of bismuth or compound thereof in the absence of added hydrogen whether extraneous or recycled.  The feedstock should boil within the gasoline or naphtha range and preferably comprises C5-C7 hydrocarbons, such as a straight-run distillate or may be the whole or part of a catalytic reformate particularly a lower-boiling fraction or a raffinate from a solvent extraction of a reformate.  The catalyst preferably comprises 5-25% chromia, 0.1 to 5% bismuth oxide, and 0.1 to 5% alkali metal oxide (e.g. potassia).  Space velocities of 0.1 to 1 vol./vol./hr. are used.  In a typical example a low-boiling fraction of a platinum reformate (end point 108 DEG  C., research octane number 76.1) was treated at 530 DEG  C. atmospheric pressure and 0.2 vol./vol./hr. with (a) 10% chromia on alunina with 1% bismuth oxide to give 65.8% of a product of octane number 101.1; (b) the same catalyst with 1% potassium oxide to give 66.6% of a product octane number 102.8.  The first Provisional Specification also refers to the use of chromia-alumina catalysts containing a minor proportion of bismuth, tin or antimony and a minor proportion of potassium, rubidium or caesium.  Specification 820,403 also is referred to.
Patent GB-1301764-A (GB)
IPC: G07D5/00
Filed: 1971-06-15
Abstract: 1301764 Testing coins A HINTERSTOCKER 15 June 1971 [16 June 1970] 28000/71 Heading G4V Electronic coin testing apparatus comprises means for generating a signal dependent upon the difference in properties of a coin 44 travelling down a coin shoot 10 (see also Fig. 2, not shown) and a standard coin 18, said difference signal changing from a predetermined value to zero and back again as a coin identical with the standard coin passes a given location in the coin shoot, a threshold device 34 which produces an output signal only if said difference signal falls below a certain numerical level and discriminating means for actuating a gate (20) to accept a coin only if there is a single threshold output signal not followed by a second such signal within a predetermined period. In the embodiment described, the difference signal is obtained by subtracting the induced voltages in secondary coils 14, 16 that are spaced on either side of a common primary coil 12 connected to an oscillator 26. After amplification and rectification the difference signal A is applied to a Schmitttrigger 34, the threshold output B from which is applied to the setting terminal of a flip-flop 36. If the attentuation properties of the coin being tested lie within a certain range (Examples 5, 6 and 8 of Figs. 4 to 9, not shown) only a single threshold output pulse is obtained, this pulse setting the flip-flop to give an output C which after a time delay provided by a circuit 38 energizes a solenoid 28 to withdraw the gate (20) from the shoot and allow the coin to pass to an acceptance channel (22). The output D from the time constant circuit 38 is further applied through another delay circuit 42 to reset the flip-flop 36. If, however, the coin lies outside the acceptance range (Examples 7 and 9), then either no or two threshold output pulses are obtained, in the latter case the second pulse resets the flip-flop before the time constant circuit 38 can respond sufficiently to energize the solenoid 28 and the gate (20) remains in the shoot diverting the coin to a reject channel (24).

Abstract: 489,143. Type-bar-making machines. SCHWEIZERISCHE LOKOMOTIVUND MASCHINENFABRIK. Oct. 15, 1937, No. 28082. Convention date, Oct. 15, 1936. [Class 100 (iii)] Assembling and distributing dies.-Relates to type-line composing and printing machines, and particularly to means for transferring the assembled line from the assembling point to the printing position and from there into the elevator in a straight horizontal path. The type are delivered from a magazine to a linechannel 2 by belts 3 and a star-wheel 4, the advancing line 1 being supported by a finger 5 on a sliding rod. When the line is completed, it is pushed to the left by a pusher-rod 16, operated by a lever 11 and a cam 12, to a position above two spaced grippers 45, 46, by which the line is further transferred. The grippers are mounted on a vertically sliding plate 21, which is raised by levers 24 and a cam 29, so as to cause the grippers to embrace the line. The right-hand gripper 45 is adjusted in accordance with the length of the line, and, on the rise of the plate 21, the left-hand gripper escapes from a stop and is drawn against the line by a spring 47, which connects the two grippers. The grippers are then moved to the left by rack-mechanism driven from a shaft 34, so as to carry the line beneath a drum 70, by which the printing is effected. The left end of the line abuts against a stop 50 carried by the plate 21, and the right-hand gripper is arrested by a stop 53. The rise of the plate 21 causes the finger 5 to be turned out of the line-channel, upon which it and the pusher-rod 16 are returned to initial position by springs. Simultaneously with the movement of the grippers 45, 46 to the left, a slide 55 carrying an ejector 61 is moved to the right. The descent of the plate 21 causes the ejector to be projected behind the line. When the grippers return to the right, the slide 55 moves to the left, and the ejector 61 transfers the line to the elevator 62.
