Abstract: 294,585. Canadian Automatic Ticket Recorders, Ltd., (Assignees of Curtis, J. de H.). July 26, 1927, [Convention date]. Type-wheel machines; index setting-arrangements; hammer-impression arrangements.-Relates to apparatus for printing and issuing tickets with two independent numbered characteristics as well as other letterpress on front and back, and for registering the totals of separate classes and of the whole of the classes issued on counters. The particulars to be printed are for racing purpose and comprise a code, the name of the meeting, the number of the race, and the number of the horse. The race number type wheel 47, Fig. 5, is set by turning a knurled head 53, Fig. 1, with indicating scale, and the horse number is set by depressing a single key 85 of a series mounted loose on a shaft 82, the hubs being shouldered to engage differentially-cut shouldered collars 102 fast on the shaft, the keys having notched detent pieces 87 to engage retaining catches 88 mounted fast on a shaft 90 so that depression of a key releases that previously depressed. The differential setting of the shaft 82 is transferred by a toothed sector and pinion to the shaft of the type sector 46 which together with the race number type wheel 47 is arranged under a platen 44 spring mounted on an arm 43 on a shaft 42. The printing mechanism is mounted between two walls 23, 24 carried on the platform 10 of the whole apparatus which stands upon pillars 11. The blank strip passes from a supply roll 13 through a guide, under a type roll 30 for printing a code, over a type roll 25 for printing the name of the meeting, under a cutter 58, through a guide 60<b> between the platen 44 and the numbering wheels 46, 47, and under an issuing roller 60. After setting the type wheels 40, 47 operation is effected by rocking a lever 17, the shaft 15 of which carries a toothed sector 18 gearing with a pinion on a spindle 21 connected by a pawl and one-toothed ratchet with the type roll 25, thus affording one complete turn thereto for a single to and fro movement of the lever. The type extends only halfway round the periphery of the roll 25, the rest of the roll being under type height, so that the paper remains stationary for half the revolution. The spindle 21 has a cam 39, Fig. 8, to rock a shaft 42 to operate the platen 44 through an arm 43. A second cam 54 on the shaft 21 rocks a shaft 56, Fig. 5, to operate the cutter 58, and rocks a toothed lever 63 to actuate the issuing roll 60 on a spindle 61. The strip is pressed against the issuing roll by spring-held rollers mounted on the guideway. For the number type wheels 46, 47 an ink ribbon on spools 51, 52 is employed, ink rollers 29, 31 being employed for the code and designation type. In a modification the lever 17 is formed in one with the toothed sector 18.

Compound or articulated road vehicles; couplings. - Relates to means for automatically connecting and disconnecting a four wheeled tractor and a four wheeled trailer when the two vehicles are brought close together, in such a manner that the front wheels of the trailer are raised clear of the ground when the two are connected and the whole then constitutes a six-wheeled combination. Fig. 1 shows the adjacent ends of tractor and trailer when the two are about to be connected, Fig. 3 shows the connected vehicle with the front trailer wheels 2 raised from the ground and Fig. 5 shows the front end of the trailer when it is in use as an independent vehicle. Pivoted to the trailer on axes 17 are two levers 18 with forked ends 19 which engage a transverse bar 35 on the tractor. When the tractor is backed, these levers 18 first raise the front end of the trailer from the position shown in Fig. 1 and then lower it into the position shown in Fig. 3, where abutments 39 on the levers 18 rest upon spring buffers 37 on the tractor frame and are retained in that position by spring jaws 38. The front wheel 2 of the trailer are at the same time raised from the ground by the movement of the levers 18. The wheels 2 are carried by springs on the ends of bent levers 4 mounted rigidly on a transverse shaft 5 carried in bearings on the tractor frame, this shaft being rotated when required by an arm 27 and a link connection 26 to pins 24 on the upper ends of the levers 18. When the trailer is used independently, the levers 18 are raised to the position shown in Fig. 5 and are retained in that position by hooks 22 engaging under a transverse, rod 21 which extends between the levers 18. When so raised the pins 24 on the levers 18 move along the horizontal parts of the slots in the links 26, Pins 28 on the levers 18 also engage under the ends of the bent levers 4 and prevent their displacement.

Title: Purification of crude aromatic compounds
IPC: C07C7/00
Filed: 1930-10-02
Abstract: Crude and semi-refined anthracene, acenaphthene, phenanthrene, or fluorene is purified by a fractional sublimation with vapours of a liquid compound containing the furane or hydrogenated furane nucleus such as furfural, methyl furfural, tetrahydrofurfuryl alcohol, and other furane bodies exercising a selective solvent action, with or without the addition of a vapour of a chlorinated hydrocarbon exercising a selective solvent action.  The vapours superheated if necessary are passed through the heated crude compound or the molten crude compound may be sprayed into ascending vapours of the subliming solvent, or permitted to flow countercurrent thereto, for example in a baffle tower, and the vapours may then be condensed and filtered cold or they may be cooled to the point where the solids separate out and then recirculated.  In examples (1) vapours of furfural, superheated if desired, are passed through a still containing crude anthracene and the vapour stream is condensed and filtered cold and the filtrate distilled; (2) methyl furfural vapours or a mixture of methyl furfural and furfural vapours replace the furfural used in example (1); (3) vapours of tetrahydrofurfural alcohol are used as in example (1) and the still residue may be added to a further batch of crude.  Specification 364,628 is referred to.

Abstract: 1404826 Reducing iron ore to sponge RHEINISCHE BRAUNKOHLENWERKE AG DEMAG AG and W WENZEL 26 June 1972 [26 June 1971] 29761/72 Heading C7D Iron ore is reduced by a transverse flow of reducing gas, e.g. CO and H 2 , as it passes through a furnace, the flow direction being periodically reversed. The gases leaving the furnace may, with or without the addition of fresh gas, be returned to a zone of the furnace where the charge is at a lower degree of reduction, and may be passed successively through several zones of the furnace. Finally the gases may be passed in counterflow to the descending charge in a pre-heating zone. or, after combustion, in a drying zone. The gas may be introduced to the furnace with a pulsating pressure e.g. a pressure variation of 20% at a periodicity of 1 second. In a particular embodiment the charge 18 passes downwardly through zones 26, 22 and 17 of a shaft, the reducing gas passing sequentially through the zones from inlet 1 to outlet 30 assisted by blowers 20, 30, 34, 32, the flow direction being simultaneously reversed periodically through all the zones by operation of the valves. In a different embodiment a furnace of circular cross-section is provided with radially spaced inlet and outlet valves 47, 49 &c, the gas flowing diametrically through the charge through each pair in turn. Intermingling of gas between two adjacent transverse flows may be prevented by dividing the charge into layers, by interposing thin layers of particulate ceramic, fine iron ore or lime or dolomite, or by incorporating in the charge thin plates of metal, ceramic or iron ore and binder.

Title: Improvements in vibrator test circuit
IPC: G01R31/327
Filed: 1945-11-08
Abstract: 608,869. Testing vibrators. PLESSEY CO., Ltd. Nov. 8, 1945, No. 29778. Convention date, Nov. 21, 1944. [Class 37] [Also in Group XXXVII] A device for testing vibratory interrupters comprises a circuit for keeping the interrupter in vibration and a discharge tube which is biassed to cut-off, while the contact under test is open, and has a meter in its anode circuit. As shown, the vibrator, which has upper and lower interrupter and rectifier contacts, is plugged in at 10 and is energized over a selected portion of a battery 21 and the upper part of resistance 17. Separate tubes are provided for the upper and lower contacts and are connected at will to a common meter by keys A, B. The grids of the tubes are first connected by ganged switches 53, 56 to the cathodes and resistances 66, 67 are adjusted until the meter, which has a scale of 100 divisions, is fully deflected. The ganged switches are then operated to connect with the interrupter contacts or the rectifier contacts to the tube grids. In these conditions, the grids are connected to the cathodes when the selected contacts are closed and receive a paralysing bias over resistance 17 or 18 when the contacts are open. Resistances 17, 18 are chosen to pass currents comparable with the drive and rectifier currents in the normal use of the interrupter. Although the tubes are of the thyratron type, the circuit voltages are chosen so that the grids do not lose control and the reading of the meter 65 indicates the percentage of the cycle period that the contact tested is closed. As an alternative, the anodes may be supplied with alternating current of a frequency of (say) 12,000/15,000 cycles. The set is also suitable for testing a vibrator which interrupts the circuit of its driving coil instead of shunting it.
