Title: An improved method of and means for cleaning heat-exchangers for gas-turbine plants
IPC: F28G1/16
Filed: 1945-10-25
Abstract: 606,276. Cleaning heat-exchanger tubes. AKT. - GES. BROWN, BOVERI, & CIE. Oct. 25, 1945, No. 28175. Convention date, June 21. [Class 99 (ii)] A method of removing soot from the heatexchanger tubes of gas-turbine plants, the surfaces of which are subjected on one side to air under pressure and on the other side to gaseous products of combustion, is characterised in that part of the air traversing the tubes for the operation of the turbine is utilised for this cleaning. Single tubes a are constructed as air-jet tubes by being perforated at g so that air can blow out. The air traverses the other tubes in the direction d and is let into one end of the tube a by means of a valve c. The other end of the tube a can be stopped as at b or provided with a valve similar to c so that some of the heated as well as the cold air can be used for the cleaning.

Abstract: 533,938. Street &c lamps. GENERAL ELECTRIC CO., Ltd., and BEGGS, S. S. Oct. 26, 1939, No. 28739. [Class 75 (iv)] In a street or like lamp a light source 1 is surrounded by a rectangular or other opaque enclosure 2 having one or more apertures each of which consists of two slots 3, 5 with highly absorbing surfaces between them, whereby all emerging light passes through both slots. Direct light falling on the slot 5 and emerging from the slot 3 does not fall on any diffusing surface, whilst light reflected from the interior of the enclosure to the slot 5 cannot change its direction before issuing from the slot 3 except by reflection from matt, black or like surfaces which reduce its intensity substantially to zero. The lamp is placed above the pavement, the interior of the enclosure has a white or other highy reflecting surface, and the slots 3, 5 have their edges 7, 8 and 6, 7 in the desired limiting planes 10-10, 11-11. The slot 5 may be formed by a flat baffle 4 constituting a light trap, and this baffle, together with the slot 3, preferably extends the full width of the enclosure. The baffle 4 may be replaced by a right-angled baffle 4<SP>1</SP>, and the edge 8 may coincide with the corner 8<SP>1</SP> of the enclosure. Direct light falling on adjacent parts of the enclosure below the baffle 4 and to the right of plane 11-11 may be caught in additional light traps, or allowed to pass through holes in the enclosure and thereby provide illumination between the lamps. The angle between the planes 10-10, 11-11 may vary from 90 degrees to .180 degrees, the slots 3, 5 need not have a common edge 7, and, instead of the slots being parallel-sided, either or both of the edges 7, 8 may be bent.

IPC: F02B75/04
Filed: 1927-05-04
Abstract: 287,595. Mahony, J. May 4, 1927. Variable-speed and reversing epicyclic gearing.-The output of an engine is automatically divided between the load or resistance to be overcome and a supercharger or fuel pump for the engine by differential mechanism placed between the engine and the load and supercharger or pump. As shown in Fig. 2, the engine shaft 1 drives the planet carrier 3 of a bevel differential gear through the wheels 1a, 3a. The two sun wheels 2a, 4a of the gear are connected to the load shaft 2 and to the pump drive shaft 4. The pump therefore forms a movable abutment for the drive, and its resistance effect may be varied by throttling the delivery outlet or by varying the crank throw used to drive the plunger 5a. An eccentric or crank drive may be used for the plungers and coaxial pumps may be used. In place of a piston pump a rotary pump 5, Fig. 7, may be used connected to the planet carrier 3, the drive and load shafts 1, 2, being connected to the other wheels. Spur differential gear mav be used. One method of varying the crank throw consists in connecting the plunger 5a, Fig. 10, to the end of a lever 16 rocked by the eccentric 4b on the shaft 4, the pivot of the lever being adjusted through the spring 14, the holder 14<x> being movable. In a revolving cylinder engine the cylinders 13, Fig. 9, are mounted on or from the planet carrier, the load and pump 5 being connected to the sun wheels. Variable driving in two directions is effected by the use of two differential trains and two pumps. Variable-speed ratchet gearing.-Instead of the differential gear a floating lever or its equivalent may be used to divide the engine output. The engine pistons 51a, Fig. 14, mav be directly connected to a lever 50, whose ends drive the pump plungers 52a and through a ratchet device 53 the load shaft 2. In a modification of this arrangement, separate air and fuel pumps are connected to the lever 50 which is driven from the crank shaft. The output may be divided by the use of three links connected to the engine, load and pump. In another arrangement the drive is divided by a pair of links 65, Fig. 17, driven from the engine crank shaft through guides 64 and links 61, 62. The rods are each connected to a pump and at their junction to a uni-directional drive 70 for the load shaft 2.

Abstract: 629,732. Electric igniters. ZANDERS, M. B. Oct. 30, 1947, No. 29014. [Class 75(iii)] [Also in Group XXXVII] The element of an electric lighter for cigarettes or the like is enclosed in a box to prevent the cigarette from touching it, said box being provided opposite the element with one or more openings to which the cigarette is applied. The base 11, heater element 14 and associated switch parts of the lighter are enclosed in a box 30 which normally stands e.g. on a table but may be held in the hand during use. The base 11 is secured to the bottom 31 of the box, two apertures being provided for connection pins 16, 16A secured to the base 11 by nuts 18. The pins 16, 16A are adapted to fit into a socket at the end of a flexible supply lead. Four oblong apertures 41, too small to admit a cigarette, are formed in a slightly sunk tray 42, let into or formed in one side of the box opposite a central hole 15 in a former 13, which is notched to receive the element 14 wound thereon; four air holes 43 are provided in the side opposite the tray 42. The former 13 is connected, together with the ends of the element 14, by screws and nuts 9 to two metal lugs 12, 12A upstanding from the base 11. The nut 18 of one connection pin 16 retains a horizontal portion 21, of the lug 12, in electric contact with said pin, while the nut 18 of the second pin 16A holds this pin in electric contact with one arm of an L-shaped piece of metal 19, the other arm of which forms the fixed switch contact. A horizontal portion 22, of the lug 12A, is riveted to the base 11 and is extended upwards at 23 into a U-shaped portion 24, the limbs of which are apertured to guide a push rod 25, which is spring-urged upwards through a hole in the top 34 of the box 30 so that its contact tip 25<SP>1</SP> is normally held away from the fixed contact. Depression of the rod 25 closes the circuit whereupon the element 14 heats up sufficiently for a cigarette applied against one of the apertures 41 to be lit by drawing upon it.
