Title: Improvements in gas generating apparatus
IPC: C10J3/00
Filed: 1921-01-08
Abstract: 157,239. Brocker, H. Nov. 29, 1917, [Convention date]. Gaseous-fuel furnaces; gas-producer furnaces. -Series of retorts b alternating with heating flues c, are interposed between gas-producers a which together with the flues c, are connected to a common gas main g which extends the whole width of the plant. The walls of the producers and the retorts are made of the same thickness and dampers h are provided whereby the flues c can be individuallv cut out in order that repairs can be effected without interruption. The flues c are regulated by dampers d, operated through closable openings e, the combustion products escaping through passages m, n to zigzag passages adjacent to the air heating flues k and from thence to the outlet flue p. Air, admitted at k<1> is preheated in the flues k and issues through apertures i and mixes with the gas flowing past the damper h. The producers are provided with charging openings a' and with gas ports f in connection with the main g. The retorts are oblique and have charging openings b<1> in line with a<1>. In the Specification as open to inspection under Sect. 91 (3) (a), part of the gas generated in the production is withdrawn through a distillation pot, the remainder passing to the main g. When a number of producers are used, the lower part of each producer may be charged with coke and the upper part with coal, the producer being used firstly as a distillation retort which is heated, in common with the retorts proper, by producer gas from other generators. When the coal has been converted into coke the generator is used as a producer the gas from which is used to heat other generators and retorts. The producers may be divided into upper and lower chambers by oblique partitions which extend over the greater part of the length of the producers, the upper chamber being operated as a distillation chamber. In another form, the gas producers are not directly associated with retorts and the producers consist of vertical chambers spaced apart by heating flues, the upper part of the chambers being heated by gas generated in the lower parts of the producers. Part of the gas is burned in the heating flues and part withdrawn at the top of the chambers. The air supply is heated in horizontal regenerator passages situated below the heating flues. The producers are started by a fire on a grate which is removed when the producers become operative. This subject-matter does not appear in the Specification as accepted.

Filed: 1961-01-11
Abstract: 937,463. Counters. MOSCOVSKAYA PECHATNAYA FABRICA GOZNAK. Jan. 11, 1961, No. 1151/61. Class 106 (1). A device for counting the number of sheets in a bundle comprises a rotating conical disc with a part cut away to form a thin leading edge and a pneumatic system arranged to draw the corner of the uppermost sheet over said leading edge so as to contact detecting means. First embodiment.-The conical disc 3 is placed on top of one corner of the bundle 2. As the disc rotates the top sheet is pulled up. wards by suction from apertures 13, 14, 15 so as to ride over leading edge 9 and break contact between brush 20 and terminal 19. The resulting impulse steps on a counter 23. The disc 3 is supplied with suction from a source 18. As it rotates the disc 3 works downwards through the bundle under the force of gravity. Second embodiment, Figs. 5-8. To prevent two sheets from being picked up and counted as one the disc may have a second cut-away portion 9, Fig. 6, with a suction part 34, Fig. 7, directed to pull the second sheet downwards. The top sheet covers an open passage 37 between two parts 35, 36 to pull up a diaphragm 42 in a chamber 39 connected to the system. Movement of the diaphragm opens contacts 43, 47 to advance a counter 46. Specification 744,957 is referred to.

Title: Improvements in electric starting devices for internal combustion engines
Filed: 1920-01-16
Abstract: 144,220. Imray, O., (Bosch Akt.-Ges., R.). Jan. 16, 1920. Turning-gear.-In an electric starter of the kind in which an electric motor is mechanically coupled to the engine on the closing of a circuit and is automatically uncoupled when the engine starts working, the starting-circuit is interrupted or short-circuited by electrically-operated means controlled by a source of current the pressure of which is dependent on the speed of the engine, so that the starting-motor cannot be operated when the engine is running. In the arrangement shown in Fig. 1. the starting-motor c is in a circuit adapted to be closed by an electro-magnetic switch b, which is operated when an auxiliary circuit including the coil f is closed by a switch g. The auxiliary circuit includes a spring arm k carrying a contact h<2> which normally engages a fixed contact h'. When the engine is running, it drives a dynamo l, the current from which ,energizes an electro-magnet o which attracts the contact h<2> and causes a break in the auxiliary circuit. The dynamo is connected to charge the battery a through an automatic switch p which breaks the connexion when the pressure of the dynamo falls below that of the battery. In a modification, Fig. 2, the part f<2> of the coil which operates the switch b is short-circuited by the closing of an electromagnetic switch h<1>, h<2> when the magnet o is energized, the remaining part f<1> of the coil being ineffective to operate the switch b. In another modification, the auxiliary circuit includes as auxiliary field winding, which shifts the armature of the starting-motor axially to bring a pinion on the armature shaft into engagement with the engine fly-wheel. The starting-switch may be in the motor circuit instead of in an auxiliary circuit.

One side 80 of a vertically extending, multisided chute feed 78 is oscillated in a horizontal direction and either the said one side or another side has a plurality of perforations therein so that fibres are shaken down the chute and compacted into a web which is withdrawn from the lower end 84 without air being entrapped in the chute. The fibres are fed to the top 82 of the chute from the top of a spiked apron 28 by a rotary comb 70 which also removes excess fibres from the upper end of the chute and directs the excess fibres into an overflow return channel 39. The plate 80 is moved at its base by shaker arms 94 and oscillates about a pivot point 126 at its upper end; the speed of oscillation being regulatable in dependance on the working speed of the subsequent textile equipment through switch 180, valve 182, air cylinder 184 and double grooved pulley and belt arrangement 50, 52, and 118. Similarly the speed of rotation of feed rollers 22, 24 feeding fibres to the foot of spiked apron 38 is regulated in dependance on the speed of the following textile equipment through role 166 and belt 172. The dimcusion &2 of the upper end of the chute is alterable. The chute may be followed by a lap winder a carding engine, or a picker which includes a beater and a screened drum under the action of suction. Alternatively a plurality of such feed chutes may feed a common conveyor.

In operation, the funnel may be withdrawn from the casing 3 independently of its position on the traverse and while continuing to reciprocate by lifting the sleeve 12 into the position shown in Fig. 3.  If desired, the assembly may then be turned about the trunnions 21 of the arms 19, Fig. 4, a pin 45 on the yoke 29 coaxial with the trunnions 32 engaging a stop 44 on the quadrant 41.  In the position of Fig. 1, the pin 45 engages a slot 43 to prevent pivotal movement of the support until the elements 12, 17 are separated.  In a modification, the pin 45 and trunnions 32 are offset forwardly of the trunnions 21.
