Patent GB-418062-A (GB)
Title: Improved means for automatic control of starting devices for internal combustion engines
IPC: F02N11/08
Filed: 1933-02-18
Abstract: 418,062. Starting prime movers ; electromagnetic switches. CARTER, F., CARTER, E., and BLACKSTONE & CO., Ltd., Rutland Engineering Works, Stamford, Lincolnshire. Feb. 18, 1933, No. 5019. [Class 38 (iv).] In an electric starting system for internalcombustion engines, e.g. compression ignition engines, closure of an initiating switch causes supply of starting power two or more times at short intervals and, if the engine then fails to start cuts off the power altogether. Closure of the initiating switch causes passage of current through a solenoid 1 and starting switch 3 in the starter motor circuit; a dash-pot 2, 5 controls the movement of the solenoid armature 4 and, after a predetermined time a snap mechanism 9, 10 operates to open the starting circuit switch 3. The armature 4 now descends and re-operates the switch 3 to cause re-starting. A lever 6 secured to the armature 4 operates, through a toothless operating pawl arm 13 of the friction type to raise a rod 11 and attached stop 12 step by step for each stroke of the armature 4 until, after a plurality of unsuccessful starts, the stop 12 abuts the arm 6 and prevents return of the armature 4 for further restarting. A circuit controlling the fuel supply to the engine, e.g. in response to liquid level, battery charge or other quantity influenced by running of the engine also controls a solenoid 17 which, through an armature 18 and a toothless retaining pawl arm 15 normally holds the rod 11 in any position, but which when energized allows the stop 12 to fall and releases the armature 4 so that it can fall and permit re-starting. If the engine starts, a manual or automatic device, such as the speed governor, responsive to self operation of the engine opens the starting circuit. The friction pawl arrangement 13, 15, 11 may be replaced by a toothed ratchet and pawl arrangement. Specification 415,460 is referred to.

Title: Process for degasifying coal
IPC: C10B49/08
Filed: 1955-02-21
Abstract: 793,194. Degasefying coal. STEINMULLER GES., L. & C. Feb. 21, 1955 [Feb. 20, 1954; Feb. 20, 1954; Feb. 27, 1954], No. 5132/55. Class 55 (1). Finely-divided coal is degasefied in two stages, firstly by admixture with a carrier gas produced by partial combustion of a combustible gas, e.g. product gas or water gas and at a temperature above the agglutinating temperature of the coal to destroy the tendency to agglutinate of the coal and then by heating the mixture of carrier gas and coal to complete the degasefication. The temperature of the carrier gas in the first stage may be between 800‹ and 1200‹ C. and the degasefication may be carried out in two separate chambers or in two zones of a single chamber. In the apparatus of Fig. 1, coal is injected from a nozzle 7 into a first chamber 2 where it is admixed with a hot carrier gas entering through two or more tangentially arranged ports 11, the mixture of carrier gas and coal passes to a second chamber 12 where the degasefication is completed. The coke produced may be gasefied in a separate gasefication zone. In a modified arrangement the coal may be injected transversely into a stream of carrier gas. In other modifications employing a single vertical chamber the coal is injected into the bottom of the chamber through a central orifice to meet a tangentially injected stream of hot carrier gas. The additional heating in the upper part of the chamber may be provided by injecting further hot carrier gas at one or more points or by applying external heat. The chamber may be widened above each point of admission of carrier gas so that the velocity of flow of the carrier gas and coal remains constant.

Abstract: 408,087. Regulating the warp tension in looms. CAMPS, J. P., 80, Colomer Street Sabadell, Spain. Feb. 28, 1933, No. 6019. [Classes 142 (i) and 142 (ii).] In a device for slackening the warp threads when the shuttle remains in the shed, the swell lever normally acting against a bowl 39 rocks a lever 43, but fails to do this if the shuttle is not boxed. A part 43b on the lever 43 thereupon remains in such a position that at the beat up it rocks a spring-controlled lever 1 and operates a push rod 6, which has a spring controlled sliding piece 10 connected by links 13 to a lever 16. The serrated end of the rod 6 then engages and rocks the lever 16, which is connected to a bracket 18 carrying the upper back roll or tube 19. The warp threads which pass over this roll &c. and over a roll &c. 20 are thus slackened. The bracket 18 is adjustably connected by a spring 21 to an arm 17 fixed to a sleeve in which the spindle 50 of the roll &c. 20 is rotatable. The arm 17 coacts with a stop 18<a> on the bracket 18 and its weight tensions the warp threads. As the warp tension varies, the bracket 18 and lever 16 rock, the connecting rods 13 and part 10 sliding on the push rod and preventing this from dropping so that it is always ready for actuation by the lever 1. The arm 17 and its sleeve are also rocked as the warp tension varies, a lever fixed to the sleeve controlling unwinding mechanism, this lever functioning similarly to the lever K described in Specification 392,739. Stop-motions.-The lever 43 controls parts 44, 46 whereby the ordinary stop lever is actuated as described in Specification 396,518.
