Title: Improvements in and relating to the recovery of waste heat from furnace gases
IPC: F28D7/08
Filed: 1935-09-24
Abstract: 456,999. Regenerative furnaces. BRASSERT & CO., Ltd., H. A., DAWSON, H. C., and THOMSON, T., Brook House, Walbrook, London. Sept. 24, 1935, No. 26493. [Class 51 (i)] In a method of waste heat recovery for furnaces in which the waste combustion gases are passed successively through heat-exchangers arranged in series, the fuel is preheated by one exchanger, the combustion air by the other, at least one of the exchangers is of metal and the waste gases are maintained continuously in contact with the second heat-exchanger. The Figure shows the invention applied to a continuous billet reheating furnace. Waste gases pass through a recuperator b which preheats the fuel gas and a recuperator c which preheats the air supply. The air and gas are supplied under pressure through pipes k and g respectively. The burner j is preferably of the type described in Specification 243,222, [Class 51 (i)]. The air supply is controlled in accordance with the gas supply by means of a regulator m of the type described in Specification 224,655, [Class 8 (ii)]. If desired, the gas supply may be automatically controlled in accordance with the temperature or pressure within the furnace. A damper o in the flue may be automatically regulated to maintain a constant draught at any point such as s in the furnace. The temperature of the heat-exchangers may be controlled automatically or manually by the addition of cool waste gases at the point p. Burners may be provided at the sides and ends of the furnace, those at the ends having insufficient air for complete combustion and those at the sides having an excess of air sufficient to complete the combustion of the partially burnt gases from the end burners. In a modification, the first heat-exchanger comprises a reversible regenerator with checkerwork as described in Specifications 325,789, [Class 51 (i)], 355,674, and 389,881.

Title: Improvements in or relating to hydraulically operated means for driving intermittently moving apparatus
IPC: F23K3/10
Filed: 1935-09-27
Abstract: 463,630. Hydraulic apparatus. INTERNATIONAL COMBUSTION, Ltd., and MEAD, H. Sept. 27, 1935, No. 26753. [Class 69 (ii)] [Also in Group XXX] A reciprocable member is operated by liquid pressure to actuate intermittentlymoving apparatus, such as the feed screw of an underfeed stoker, to which it is coupled by a unidirectional, mechanical connection. The stroke is determined by an adjustable stop in the path of an operated part, and the consequent increased pressure is released when the stop is engaged. The feedscrew T is rotated by the cylinder A in the direction of the arrow through pawls Q<1> Q<2> carried on a disc on the screw and by an annular ratchet wheel E loosely mounted on a disc on the screw and driven forward by the cylinder. A cylinder B effects the idle movement of the disc E of the return of the cylinder A. Diametrically-opposed teeth N engage racks A<1>, B<1> on the cylinders A, B which move on stationary rams C, D supplied with oil from a plunger pump through pipes X, Y connected to chambers K, F, each provided with inlet and relief valves. The valves G and H<1> open below and above pressures of prepredetermined value respectively. A nut H<x> admits adjustment of the spring of the valve H<1>. The plunger L is reciprocated by a powerdriven crank. When pressure enters pipe X, the cylinder is moved until it strikes a fixed stop R and the screw is rotated. The cylinder B is retracted during this movement. When the piston L moves to the right, the motion of the cylinders is reversed. The starting positions and stroke of the cylinder A can be varied by an adjustable stop M which engages the toothed segmental member N. When the stop is engaged, excess oil in the cylinder is forced into the reservoir. Excessive rise in pressure during the power stroke of cylinder A is prevented by valve H<1>. A number of oil leads X, Y could be taken to drive different apparatus without using extra valves.

Filed: 1925-10-27
Abstract: 256,089. Trail, H. H. Oct. 27, 1925. Turning-gear. - A pinion 8, freely mounted on the shaft 1 of an electric or other starter, is connected by a pin and cam connection to the shaft, the cam 12 having an endless surface so shaped that rotation of the shaft causes axial movement of the pinion at a gradually increasing velocity until the pinion is in mesh with an engine gear 16, and subsequent rotation of the pinion by the engine causes the return of the pinion. As shown in Fig. 2, a cam slot 12 is formed in a member 3 fixed on the shaft 1. The pinion is splined to a sleeve 6 mounted loosely on the shaft 1 and is normally held bv a spring 11 in engagement with a nut 10 on the sleeve 6. An enlarged part 7 of the sleeve 6 carries a screw 13 on which is a roller 15 for engagement with the cam slot 12. The development of the slot is shown in Fig. 4, the face a being shaped to cause the axial engaging movement of the pinion at a gradually increasing velocity and the face c being similarly shaped but terminating in a circular portion to allow rebound before coming to rest. The screw 13 may be locked in position by a split collar 14 tapered to engage recesses in the part 7 and the head of the screw. The sleeve 6 and pinion may be normally retained in the disengaged position by a spring ball 17 engaging a groove 18 in the member 3, or by a spring clip in the end of the cam slot for engagement with the roller 15. In a modification, Fig. 7, the member 25 provided with the cam slot is slidable on the shaft 1 against a spring 28 and the pinion 32 is integral with the sleeve 33, a spring 42 being interposed between the pinion and a ring 41 and the end turn of the spring engaging an annular recess in the ring.

IPC: G04B23/08
Filed: 1923-10-31
Abstract: 220,851. Kriegels, M. F. Oct. 31, 1923. Alarm and like mechanism; framework.-Means are provided in an alarm clock whereby the alarm is freed and again stopped each day automatically with one winding only. The spring-pressed slide A has detents A<4>, A<7> in the path of the tail C<2> of the hammer, and is moved sideways to free the tail by the usual pin and cam B<3>, B<4>, which allow a sideway movement of the spring-pressed wheel B<5>. By this movement, the clutch E is engaged with the pin C<5> and driven against the spring F, a projection E<4> thereby moving the slide A to the right and stopping the alarm. The continued rotation of the arbor B moves the slide sideways, restoring the projection A<4> into engagement with the tail C<2>, and freeing the clutch, which under the action of the spring withdraws the slide to its initial position. The alarm may be stopped by hand, by means of a pivoted lever G whch moves the slide to the right, in which position it is retained by a detent H<4> in a spring-controlled arm H. The slide is operated subsequenly by the arbor B<4> and clutch E, as previously described. The alarm may be permanently stopped by providing a retaining notch &c. for the slide A. The alarm may be also stopped by a pivoted lever 0, Fig. 3, having a projection O<5> adapted to engage the tail C<2>, a projection P forcing the lever sideways against the spring O<4> on rotation by hand. The slide A may also be allowed movement in the direction of the axis B, and may be restored after release by a modified form of clutch. A self-contained escapement mechanism may be provided, and the springs may be mounted outside the plates carrying the movement. A winding indicator is preferably provided and the alarm-set dial is divided into an A.M. and P.M. period against which distinctive colours are shown. The change of colour is effected suddenly by actuation with a cam such as a double snail cam.
