Title: Improvements in and relating to the control and regulation of combustion in producergas furnaces
IPC: C10J3/80
Filed: 1926-02-05
Abstract: 247,215. Steinbart, A. Feb. 7, 1925, [Convention date]. Air supply, regulating.-In furnaces fired with producer gas, separate independently-driven blowers are provided for the supply of primary air to the gas producers and of secondary air to effect combustion of the gas in the furnace and the correct relative speed of the blowers is maintained by means actuated in accordance with the variations in the flow of the primary air or of the secondary air or of both. As shown in Fig. 1, the suction pipes 11, 11<a> of the blowers 5, 5<a> driven by steam turbines 9, 9<a> are provided with stabilizing-chambers 15, 15<a> having inlet orifices 16, 16<a> about one-half of the areas of the inlet ports of their respective blowers. The areas of the orifices 16, 16a are also proportional to the primary and secondary air supplies. The pressure in the stabilizing-chambers is communicated to liquid-sealed bells 13, 13a mounted on a lever 17. Upon starting the blower 5, the bell 13 is lowered and the lever 17 controls a motor 18 connected through a cord 19 to a valve 20 so as to admit steam to the turbine 9<a> and start the fan 5<a>. The static pressure in the chamber 15a is reduced and the bells 13, 13a come to rest in their normal position, the supplies of primary and secondary air being maintained in the correct proportion. In a further modification shown in Fig. 3, the bells are each divided into two compartments 22, 23 and 22a, 23a. The compartments 22, 22<a> are connected by pipes 26, 26<a> to the primary air supply main 6 so as to be actuated by the flow of air therein and the compartments 23, 23a are similarly connected through pipes 27, 27a to the main 6a so as to be actuated by the flow of secondary air. The bells are arranged to operate the valve 20 as described above. Instead of controlling the secondary air in accordance with the primary air, the operation may be reversed. Steam-jet blowers may be provided for supplying air to the producers. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the form shown in Fig. 1 (Cancelled) in which blowers 5, 5<a> driven directly by a motor 9 deliver air in definite proportions through pipes 6, 6a respectively to the producers 1 and to the furnace, and change-speed gear may be arranged between the motor and one of the blowers. This subjectmatter does not appear in the Specification as accepted.

Filed: 1940-02-23
Abstract: 537,315. Actuation of switches; motor controllers. BRITISH THOMSON-HOUSTON CO., Ltd., and WISE, W. L. Feb. 23, 1940, No. 3449. [Classes 38 (iii) and 38 (v)] In a switch particularly adapted for interchanging the connections of a multiple-wound induction motor, movement of a shaft 11 axially causes longitudinal movement of rods 15 and contact carriers 5 till the contacts they carry are opposite selected contacts 2a, 2b ... 2f on two base plates 1 arranged on opposite sides of the rods 15 and carriers 5; rotation of the shaft from its central position in either direction then causes sideways movement of the rods 15 and the engagement of the contacts on one or other of the two base plates 1. An additional longitudinal movement of the rods 15 may also cause, through a member 19, the movement of a rod 17 against the action of a spring 20 so that contacts 18 are brought into bridging engagement with pairs of contacts 16 on the two plates 1. Closure of these contacts causes current to be supplied tending to reverse the motor so that a. braking effect is produced quickly stopping the motor. The axial and rotary movements of the shaft 11 are produced by a lever and gate mechanism, Figs. 5 and. 6 'not shown).

Abstract: 1332884 Ski bindings P MULLER 31 Jan 1972 [29 Jan 1971] 4335/72 Heading A6D A heel binding for a ski 35 comprises a housing 11 having a cavity with a slightly inclined axis 12, the cavity having three portions 13-15 of increasing size. A slideable plug 16 is located in the cavity and one end 45 thereof projects through the front of the housing to engage a depression 44 in or attached to a ski boot. A spring 22 urges the plug 16 forwards and the spring is adjustably loaded by a screwed bolt 21 in a bush 18. A lateral recess 25 is provided on each side of the housing, side plates 28 being located between walls 26 to define two internal cavities each housing an eccentric cam disc 31. The cam discs 31 are mounted on respective pivot pins 30 which are rotatably journalled in co-axial cross bores 29 in the side plates 28. An external lever 33 connects the pivot pins 30. As shown in Fig. 1 the lever 33 is approximately horizontal and the plug 16 is in the boot engaging position. As the lever 33 is rotated anticlockwise the cam discs 31 are rotated to bear on an abutment 17 of the plug 16 to retrack the plug against spring 22, the retraction being at a maximum when lever 33 is approximately vertical. Further rotation of the lever 33 causes a flat 49 on each cam disc 31 to engage abutment 17 such that the lever is slightly to the left of vertical and the plug 16 is still retracted into the housing. In this position a sliding member 37 on the lever 33 may engage the rear of the boot to allow pivotal movement of the boot about a centre on the ski surface adjacent the toe, the lever 33 being curved with the centre of curvature being approximately conicident with said centre to allow walking action while retaining the boot on the ski.  The end 45 has a small radius of curvature in vertical section and a large radius of curvature in horizontal section to allow different release forces for vertical and sideways stresses. All parts except for spring 22 may be of plastics materials.
