Title: Process for the selective hydrogenation of hydrocarbon oils
IPC: B01J23/70
Filed: 1961-01-12
Abstract: Light cracked diene-containing hydrocarbon oils, having a final boiling point of not more than 375 DEG C., are contacted with hydrogen in the presence of a nickel catalyst supported on a carrier containing at least one alkaline earth metal sulphate which is soluble or substantially insoluble in water, the average catalyst temperature being not greater than 160 DEG C., thereby hydrogenating the dienes, and other highly reactive unsaturated compounds present. The carrier is preferably barium sulphate, and the catalyst preferably contains 1-25% by weight of nickel.  The oil may be obtained by thermally cracking a gasoline, for example one having a final boiling point of not more than 230 DEG C., in the presence of steam.  Preferably the oil has a sulphur content of less than 0,1% by weight.  The catalyst may be employed in the fluidized or suspended state, but is preferably in the form of a fixed bed employed in the trickle technique, for example as described in Specification 657,521. The pressure is preferably between 10 and 60 atmospheres absolute.

Title: Balun transformers
IPC: H01F19/06
Filed: 1973-01-10
Abstract: 1417093 Baluns; transformers TECHNOLOGY FOR COMMUNICATIONS INTERNATIONAL 10 Jan 1973 [17 Jan 1972] 1378/73 Headings HIT and H1W An impedance-transforming balun comprises a single high-permeability magnetic core 12 and windings 14 around different parts of the core connecting an unbalanced input 15 to a gap 18 across which a balanced impedance is normally available, this balanced impedance being further transformed in a desired ratio by reducing or increasing the number of turns between the input and the output. At the gap 18, the inner conductor of one winding is conductively connected to the outer conductor of the other, and the impedance appearing across the gap is equal to the input impedance. In order to secure a transformation ratio, the output is derived across terminals 25, 26. If the number of turns between the input terminals and terminals 25, 26 is N s /2, and the number of turns between the input terminals and the gap is N p /2 (where N s  # N p ) then an impedance transformation ratio of (N s /N p )<SP>2</SP> is secured. In Fig. 1, N s  < N p  and a balanced impedance Z B  less than the unbalanced impedance Z u  is the result. To secure an increase in impedance, the output terminals 25, 26 are connected to the gap by means of extra singleconductor windings 31, 32, Fig. 3. In this case, N s  > N p . The results are true so long as the lengths of the conductors are a small fraction of a wavelength at the frequency of operation. The lower limit of the frequency-operating is fully discussed in the Specification. Near the upper limit, the windings 31, 32 and the windings 14 form a two-conductor transmission line, and, in order to obtain reflectionless transmission along it, it is necessary to provide a gradually increasing characteristic impedance between the gap 18 and the output terminals 25, 26. This may be done by gradually increasing the spacing of the turns (see Fig. 5, not shown). Further, in order to minimize coupling between adjacent turns of the two windings, the windings 31, 32 may be connected to the outer conductors of windings 14 at two diametrically-opposite points (see Fig. 5, not shown) instead of directly across the gap (as shown). In the modification of Fig. 6, one half of the winding is constituted by an unbalanced three-conductor transmission line 41 and the other half by a single wire 46. The mode of connection at the balanced and unbalanced ends of the balun is apparent from the figure. To provide impedance transformation, connections are made as in Fig. 1, or Fig. 3, e.g. for Z B  < Z U  one balanced terminal is connected to an intermediate point on conductor 46 and the other to intermediate points on conductors 43, 44.

Title: Improvements in coin controlled sales apparatus
Filed: 1929-01-15
Abstract: 305,095. Eller, F. Jan. 30, 1928. [Convention date]. Testing coins; returning coin; coin action, multiple - coin; ticketprinting apparatus.-In a coin-controlled sales apparatus, for example for selling tickets, freed by a plurality of coins, which are collected in a receptacle before passing to the money-box, the collecting-receptacle is controlled for delivering the coins to the money box by the power released by the last coin which operates in the proper way to (), actuate the mechanism, while the coins are returned to the outside of the apparatus by the operaticn of a button when the last coin fails to release the power or is not inserted. In the application to a ticket printing and delivering machine, the last coin of a set controls an electromagnet 14 which actuates the printing and delivering mechanism 16, the coins inserted through a slot 1 passing through a coin testing mechanism 2 from which they drop through a pair of shoots 3. One shoot leads direct to a receptacle 6 having a pivoted bottom 7 and a pivoted side 8, the other shoot leading the last coin through the mechanism 16 and then to the receptacle 6. When the electromagnet 14 is energized, it opens the side 8 by acting through a lever 22 and link 15 to discharge the coins in the receptacle 6 through shoots 9 to money-boxes 4, 5. If the last coin fails to pass the testing mechanism 2 or the mechanism 16 fails to operate, the operator by pressing a knob 12 opens the hinged side of the testing mechanism through a link 17 and the bottom 7 of the receptacle 6 through a link 13. The coins in the receptacle are then returned through a shoot 10 to an outside tray 11 and the coin in the testing mechanism to a tray 23.

Title: Improvements in or relating to transducer apparatus
IPC: G11B5/004
Filed: 1955-01-18
Abstract: 764,352. Magnetic recording and reproducing apparatus. FELT & TARRANT MANUFACTURING CO. Jan. 18, 1955 [Feb. 8, 1954], No. 1497/55. Class 40 (2). In a magnetic transducing apparatus having a record carrier 7 in the form of a wide cylindrical loop passing over a revolving cylinder 6 and having perforations 20 along one edge, a transducer 12 is traversed along the cylinder by a leadscrew 9 which may be manually adjusted axially by means of a cam 88 at one end thereof to effect correct registering of the transducer and the record track. In operation, the loop 7 is held taut by a roller 13 on an arm 23 which in the inoperative position is held in one or other of the dotted position shown in Fig. 6 by a spring-loaded arm 29 engaging notches 26 or 27 in the arm 23. The lifting and lowering of arm 23 also effects starting and stopping of the driving motor 8 by means of a cam 92 on shaft 24 which operates a switch 93. The motor 8 drives the cylinder 6 via shaft 41 and friction gears 42, 43, 44, the gear 42, 43 being a jockey pulley moved into engagement with shaft 41 and gear 44 by a solenoid 53 which causes the movement of a slide 45 on which the gear 42, 43 is mounted. The leadscrew 9 is driven from the cylinder shaft 16 by toothed gears 63, 64, 65, 66. Reverse drive is effected by a further jockey pulley 54 mounted on a cranked lever 57 and brought into operation by solenoid 60. The transducer is pivotally mounted at 71 on a carriage 11 drawn along a guide rod 10 by the leadscrew 9 against which a follower 77 is pressed, under the influence of a counter-weight 97. The transducer may be moved manually along the cylinder by first lifting it whereupon a spring clip 79 on the transducer engages a detent 80 on the carriage 11, and locks the transducer in an upper position. The weight of the transducer thus overcomes the effect of the counter-weight 97 and causes the follower 77 to be disengaged from the leadscrew 9 and flat surface 76 to press against the leadscrew to prevent the transducer re-engaging the record. While in this condition the transducer may be freely moved either way along the cylinder. When it is desired to restore engagement of the transducer with the record it is merely necessary to press the transducer towards the record, whereupon the clip 79 becomes disengaged from the detent 80, and the original condition is restored.
