Title: Improvements in and relating to high speed suspended railways
IPC: B61B3/02
Filed: 1928-04-25
Abstract: 289,776. Stedefeld, C. April 30, 1927, [Convention date]. Single-rail and suspended vehicles.-In order to enable torpedo - shaped suspended railway vehicles for high speeds to be formed into trains, one or both ends of each vehicle is removable so that the vehicles can be arranged close behind one another, the abutting ends being of substantially equal crosssection. In forming a train of vehicles, driven by air-propellers, as in Fig. 1, the rear pointed end 27, Fig. 3, which is secured to the propeller shaft 43 by a bolt 45 is removed from the three forward vehicles 12 - - 14 and the nose of each of the three rear vehicles 11 - - 13. shown as sectors 26<a>, 26b, Fig. 4, is turned back as shown in full lines to shorten the overall length of the train. Couplings 15 - - 17 connect the vehicles and relative side swaying of the vehicles is prevented by means of a tongue 56, Fig. 6, on an extension of the propeller nut on one vehicle engaging between two spring supported plates 57<a>, 57b on the opposing vehicle, the extension of the nut or of the shaft 43 running in bearings 62 in the tongue. Instead of a tongue for aligning the vehicles a recess may be formed in one or both ends of a vehicle, not driven by an air propeller, into which the pointed end of an opposing vehicle enters.

Title: Improvements relating to single-phase induction motors
IPC: H02K17/30
Filed: 1932-04-27
Abstract: 384,895. Alternating-current commutator motors. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and BALL, R. D., Phoenix Works, Bradford, Yorkshire. April 27, 1932, No. 12151. [Class 35.] A variable speed two or three-phase induction motor of the commutator type operating on single-phase mains, in which brushes are movable on the commutator in order to vary the voltage impressed by the commutator winding upon the secondary-winding, is started by inserting capacity in series with one phase of the primary winding, and when the motor has run up to speed, the said phase remains in circuit with a reduced capacity in series. The invention is applicable to motors of the Schrage type and to modifications of such motors employing two commutator windings. In Fig. 1 the rotor carries primary windings 1, 2 and a regulating winding 7 connected to a commutator 8 upon which bear brushes connected to the separate phases 9a, 9b, 9c of a three-phase secondary stator winding. The primary windings are connected.by means of slip-rings 4, 5, 6 and a switch 13 to single-phase mains A, B and to condensers 11, 12. In the starting positions, contacts 14, 15, 16. of the switch are closed and the condensers 11, 12 are in parallel and.in series, with primary phase 2. With the switch in the running position, contacts 14 remain closed, contacts 17 are also closed and contacts 15, 16 are open so that the condensers 11, 12 are connected in series in the circuit of phase 2. The Specification describes also a three-phase motor in which the primary phases are delta connected and brought out to slip rings, the remaining connections being as shown in Fig. 1. A single 3-plate condenser may replace the condensers 11, 12. Instead of changing the condenser connections from parallel to series, one may be cut out of circuit as described in Specification 382,209. The switch may be operated manually or automatically. Usually the starting winding phase 2 has more turns than phase 1 and if the motor is to be reversible the ends of the phases 1, 2 are brought out to four slip rings 4, 5, 6, 18, which are connected to a reversing switch 19 as shown in Fig. 3. Where it is desired merely to allow for setting the direction of rotation, the connected ends of the phases 1, 2 in Fig. 1 are separately connected to the slip ring 6 so that the connections of phase 1 with the slip rings 4, 6 can be interchanged. Specification 385,150 also is referred to.

Moulding gramophone records; heating-apparatus.-Mould plates for records for gramophones &c. are heated by surface contact, the heat being applied by heating-elements which adapt themselves to the configuration of the surface to be heated. The elements for applying the heat may be directly heated by steam or electricity or may themselves be heated bv surface contact with a heated plate. The heating surfaces may comprise blocks 4, Fig. 1, which compose a circle but which are independently and yieldingly mounted by spindles 5 and springs 7, Fig. 2, on a plate 1 carried by an elevating spindle 2. The blocks may have tortuous channels for the passage of steam, or may have electrical heating elements mounted therein. A guard. 11 is secured to the plate 1. In a modification, in which the heating blocks 4<1>, Fig. 4, are themselves heated by surface contact with a heated bed 12, the plate 18 on which the blocks are yieldingly mounted is linked by bars 21 to a fixed pivot 22, the bars resting on pins 38 carried by an elevating member 32 to which the heating bed 12 is rigidly secured by a pin 30. On elevation of the member 32 the heating bed 12 rises therewith but the plate 18 rises at a greater rate against the resistance of springs 37 and lifts the heating blocks clear of the bed 12. The heating bed 12 may have steam heating passages or may be provided with electrical heating elements.

Title: Improvements in machines for winding yarns or threads of fibrous substances
IPC: B65H59/38
Filed: 1921-04-30
Abstract: 182,979. Smith, A., and Shackleton, G. W. April 30, 1921. Winding-machines; tension arrangements.- In a thread guiding and tensioning device for a Universal winding-machine, a spirally-wound spring 9 is arranged with its ends respectively connected, at c to a lever 10, and to a notched hub 8, the notches of which engage a pin 6a on a lever 6. The lever 6 is connected by a rod 7 to a pivoted member 2, and the lever 10 by a rod 11 to a grid tensioning mechanism 5, 5<a>. The tension of the spring 9 is regulated by rotating the hub 8 to bring particular notches into engagement with the pin 6<a>. As the diameter of the cop 3 increases, the member 2 is moved about its pivot and the rod 7 is thereby moved in a direction away from the device 5, 5<a>, thus causing the tension of the spring 9, and therefore of the thread being wound to decrease. To prevent a rebound of the member 2 when the spindle 4 is arrested by the stop-motion, the centre 2b of a gripping-groove in a bracket 12 is arranged eccentric from the pivot 2<a> of the member 2, so that the friction-lever x increases the pull on the spring y when moved back from w to w<1>.

Patent GB-495075-A (GB)
Title: Process for producing liquid fuels from gaseous olefines
IPC: C10G50/00
Filed: 1937-05-04
Abstract: In the non-catalytic conversion of gaseous olefines into liquid fuels by the action of high temperatures and pressures, the cross-sectional area of the gas flow is reduced as polymerization proceeds.  The rate of flow of the gases is thus maintained constant or increased during the reaction, and separation of carbon prevented.  When inert gases are present, the temperature may be increased as the partial pressure of olefines decreases. With a 60 per cent olefine content, temperature is about 450-460 DEG  C., with a 40-45 per cent content, about 500 DEG  C., and with 20-25 per cent, 525 DEG  C.  A gas containing 60 per cent olefines may be passed through 100 parallel tubes in a first stage to give 50-60 per cent conversion, the issuing gases and vapours then passing through 60-70 tubes to convert 50-60 per cent of the remaining olefines, and finally through 30-40 tubes to complete the conversion.  If the same speed of flow is desired, the diameters of the tubes in the second and third stages must be increased. Tubes of gradually decreasing cross-section or fitted with tapering insertions may alternatively be used.  In an example, a gas containing 61 per cent propene is passed at 100 atmos. through a three-stage system of tubes, first 3 tubes at 460 DEG  C., then 2 at 500 DEG  C., and finally a single tube at 525 DEG  C. to yield benzine.
