Title: Combustion apparatus
Inventor: MUTCHLER PAUL A
IPC: F23C6/04
Filed: 1968-01-03
Abstract: 1,216,261. Generating combustion products . under pressure. AMERICAN AIR FILTER CO. Inc. Jan.3, 1968, No.514/68. Heading F1L. [Also in Division F4] A combustion apparatus comprises co-axial combustion chambers 1, 2 respectively separated by a passage 4 of reduced diameter to produce a constructed configuration in the path of the combustion products on their way to outlet 6a leading to a heat exchanger (not shown). Combustion air from annular air intake chamber 14 is supplied through perforations 21, 22 in combustion chambers 1, 2 respectively to burn fuel injected from nozzle 3 mounted in a fuel nozzle holder 32 so as to project the fuel spray through central aperture 28 of a baffle 12 mounted at one end of combustion chamber 1, whereby a stable flame base is established. Part of the air is introduced into combustion chamber 1 through aperatures 34 in nozzle holder 32 and apertures 27 in baffle 12 to promote turbulent mixing with the injected fuel. The air from air intake chamber 14, on its way to combustion chamber 1 passes through perforations 17a in a cylindrical screen 17. At low fuel injection rates due to the pressure difference between chambers 1 and 14, a quantity of air sufficient to complete combustion in combustion chamber 1 flows thereto, excess air from supply conduit 13 passing through radial grooves 15 in refractory spacer ring 5 to combustion chamber 2 to be introduced into the combustion products only after combustion has been completed whereby any chilling of the flame itself may be avoided. At higher fuel injection rates, due to an increase in pressure in combustion chamber 1, less air from air intake chamber 14 flows to combustion chamber 1 and more air flows through grooves 15 to combustion chamber 2. In this case combustion in chamber 1 is only partially completed, the air entering combustion chamber 2 now acting as combustion air to complete the combustion process.

Title: Switching arrangement for multi-motor drives
IPC: H02P1/58
Filed: 1957-01-07
Abstract: 802,607. Control of two motors. BARMER MASCHINENFABRIK A.G. Jan. 7, 1957 [Jan. 7, 1956], No. 618/57. Class 38 (3). In a system for two motors M, N, driving a textile machine, the motor M is started first followed by the motor N after a predetermined time delay. When the motors are to be stopped, the motor N is initially disconnected, and then the motor M after the delay period. As shown, closure of-switch D energizes contactor A to connect motor M to the supply system and, at the same time, a time-delay relay Z is set in operation. At the end of the delay-period, contactor B is energized to start the motor N and the relay Z is rendered inoperative, an auxiliary relay H being energized at this time. A contact hI of the auxiliary relay interrupts one path to the coil of the contactor B, whilst contacts hIV, hIII, respectively interrupt and close alternative circuits for the contactor A. Opening of the switch D de-energizes the contactor B and causes relay Z to start a timing operation at the end of which the contactor A is de-energized.

Abstract: 130,072. Davies, W. F. W. Jan. 14, 1918. Steering and balancing.-The greater part of the trailing edge of the plane of an areoplane is adapted to be raised or lowered to vary the camber and angle of incidence of the planes, in addition to two ailerons which can be moved in opposite directions to control the lateral balance. In one form, the ailerons also may be moved in unison with the inner parts to vary the camber. Fig. 2 shows a plane having four flaps 2 - - 5 normally held in their highest positions by leaf or other springs 6. The inner, and preferably larger, flaps 2, 3 are connected by cords 7 to arms 9 on a transverse shaft 10 which has a lever 11 cooperating with a locking-quadrant 13. The outer flaps 4, 5 are interconnected by a cord 26 and are connected by cords 21 to an arm 20 on a longitudinal shaft 19, to which is pivoted a control lever 17. A modification is described in which the springs 6 are dispensed with and the flaps are moved positively in both directions, the cords from the upper side being led to upward extensions of the levers 9. Fig. 6 shows a modification in which the flaps 4, 5 are adapted to be moved simultaneously with the flaps 2, 3. The cords from the flaps 2, 3 are connected to arms on a hollow shaft 36 through which passes a shaft 37 provided with a handle 38 for controlling the elevators. The shaft 36 is turned by a lever 35. which can also swing laterally about a pivot 44 to move the flaps 4, 5 in opposite directions by means of cords 42. The cords 42 pass through fixed guides 43 and through arms 46 on the shaft 36, so that fore-and-aft movement of the lever 35 effects a simultaneous movement .of the flaps 2 - - 5. A locking-quadrant 48 engages a pawl on the lower end of the lever 35, and a similar device may be used to lock the lever in any lateral position. The flaps are secured to the plane by metal straps passed around their front spars.

Title: Improvements in or relating to the utilization of waste material
Inventor: BECKER FERENC
IPC: B03B9/00
Filed: 1961-01-09
Abstract: Coal mine waste is utilized by separating it into a coal-rich fraction and a coal poor fraction by crushing the material, suspending it in water, and passing it through a hydrocyclone under controlled conditions of grain size and density of suspension. According to the invention the density of the suspension is adjusted, by the addition of water, to 1.22-1.45 kg. per litre and the grain size of the material is not greater than 20 mm.  Also, according to the invention, at least 40% by weight has a grain size not greater than 1 mm. and the distribution of grain size under 1 mm. is: 10-30%, 0-0.05 mm.; 20-40%, 0.05-0.5 mm.; 30-70%, 0.5-1 mm.  A suitable excess pressure for the hydrocyclone is 0.5 atmosphere.  Crushing to a grain size of 20 mm. follows preliminary screening to separate a grain size not greater than 80 mm.  If crushing to an overall grain size of 20 mm. does not yield the required percentage of grain size under 1 mm. a return and refeeding process may be employed; or material of this grain size may be added, obtainable from the coal poor fraction, or from the crushing of pieces in excess of 80 mm. grain size.  The fraction having a grain size under 1 mm. may also be used as an additive in the manufacture of cement.  The coal poor fraction may be further divided, by screening, into fractions of grain size less, and greater, than 2 mm.  The finer can be used as an additive to raw clay in the manufacture of bricks.  The coarser can be used for mine-filling operations; also as an additive for low-density concrete. Detailed examples are given.  Specification 913,178 is referred to.

Title: Web guide mechanism
Inventor: HENRI GEEHAADO UIREMU PIEERUSO
IPC: D06C3/00
Filed: 1990-01-04
Abstract: PURPOSE: To correct dislocation without damaging a web by detecting existence of an edge with a single sensor installed adjacent to one edge of the web, and adjusting the spacing of pinch rollers on both sides of the web using an actuator depending upon the result from detection. CONSTITUTION: Route deciding units 10 and 40 are installed on the sides of a web, and one sensor 58 is installed adjacent to one of the web edges so that detection is made whether any web exists. The units 10 and 40 are equipped with a pair of rollers 12 and 14 and ones 42 and 44, respectively, and thereby the web is held pinchedly. The pinching force depends upon the air injection amount to bellows 28 and 48. When the web in traveling is dislocated aside to cause the sensor 58 to judge out of web, a control valve 52 is actuated to send air to that actuator on the side where the web is biased (for example, 48) so as to strengthen the pinching force of the rollers, and the dislocation is eliminated. Thus web dislocation can be corrected simply, and the web is free of risk being damaged.
