Title: Convection radiator for space heating of buildings
IPC: F28D1/03
Filed: 1950-01-04
Abstract: 675,314. Convection air - heaters. DODINO, C. Jan. 4, 1950 [Dec. 12, 1949], No. 176/50. Class 64(iii) In a convection radiator, a pair of hollow walls 8, 9 define a narrow vertical central space 5 open at top and bottom for inducing a flow of air, the interior of each wall being divided to form longitudinal ducts K which before final assembly of the radiator are open at their ends but are eventually connected to the ends of corresponding ducts in the other wall so that heating fluid may be passed through all the ducts in series. In the form shown, the ends of ducts K are bent inwardly at the ends of each wall, to be welded or brazed to the similarly disposed ends of the other wall. The longitudinal ducts K in the wall 9, Fig. 9, have an inclined portion, the ducts in the wall 8 being horizontal so that the heating fluid flows, in a continuous, flatcoiled passage formed by the ducts from an inlet R to an outlet R<SP>1</SP>. As shown in Fig. 10, the walls 8, 9 are each formed from two metal sheets pressed to form interengaging corrugations which afford welding points P and define the ducts K. In a modification, Figs. 1-5 (not shown), the outer sheets of the element are formed with semi-cylindrical flutes and the inner sheets are flat except for grooves which receive the cusps of the flutes. Duct connections of half-ring formation at the ends of the elements communicate with the passages between the sheets, those at one end being inclined to the horizontal, or the ducts in one hollow wall being inclined, in order to form the coiled passage. The duct connections may be enclosed in a cover.

Title: Anemometer with altitude correction
IPC: G01P5/14
Filed: 1938-01-04
Abstract: 489,599. Differential pressure gauges. I. S. S. A. INDUSTRIA SPECIALIZZATA STRUMENTI AERONAVIGAZIONE SOC. ANON., and CIAMBERLINI, U. Jan. 4, 1938, No. 178. Convention date, Jan. 5, 1937. [Class 106 (ii)] In a gauge connected to a Venturi or Pitot tube for indicating speed of aircraft, the movements of the usual capsule are compensated for density of the atmosphere by the provision of a second capsule which varies the ratio of the transmission gear to the indicating pointer. The main capsule 13 is connected by a pipe 14 to the Venturi tube. A shackle 16 on the capsule engages a bent arm 15 on a spindle 10 carrying an arm 9 which engages a sector 7 pivoted at 8 and driving a pinion 5 on the spindle 4 of the pointer 3. The spindle 10 rotates on conical points one of which 19 is in one with a piston 18 acted upon by a spring 17 while the other is acted upon by a lever 12, moved by the auxiliary capsule 11. This, as the aircraft rises moves the spindle 10 axially to the right causing the arm 9 to act on the sector at an increasing distance from the pivot 8. In addition, at low altitudes, the shackle 16, owing to the curvature of arm 15 acts at a closer distance to the spindle.

Title: Improvements relating to the operation of high pressure mercury vapour electric discharge lamps
IPC: H05B41/19
Filed: 1941-01-08
Abstract: 545,388. Metal-vapour lamps. BRITISH THOMSON-HOUSTON CO., Ltd., and BOURNE, H. K. Jan. 8, 1941, No. 268. [Class 39 (i)] A circuit for operating a high-pressure mercury-vapour lamp having an auxiliary unheated electrode near to one of the main electrodes comprises means for impressing a high frequency high potential between the auxiliary electrode and the adjacent main electrode to produce a discharge between them so that a discharge may be started between the main electrodes under conditions of high vapour pressure. As shown, the lamp is operated from an A.C. supply, the current being controlled by an impedance 2. In starting, the lamp is first heated by a flame or by an electrical heater so that the mercury is at the operating pressure. When the current is switched on a Tesla coil 6 starts a high frequency discharge between an auxiliary electrode 4 and the adjacent main electrode 5, producing an arc in the intervening gap, the current in which is limited by a resistance 8 to a value of the order of 5 amperes. This arc forms a heated cathode spot on the electrode 5. At the same time, a high voltage transformer 3 causes a spark to jump between the main electrodes 5 and 10. On shorting the secondary of the transformer 3 by a switch 9 an arc is formed between the electrodes 5, 10. The heated cathode spot materially reduces the value of the initiating potential necessary between the electrodes. The switch 9, which may have to be operated several times in succession to establish the arc, may be hand operated or a motor-driven contact. The circuit may be made automatic by the use of a contactor operated by the voltage drop across the impedance 2 when the lamp strikes, which causes the operation of contacts to short circuit the secondary of the transformer 3, interrupt the supply to the coil 6, cut out the lamp heater, and also to start the cooling fan if this is used. A similar circuit for use on D.C. supply is described in which the lamp is caused to strike by opening a mercury switch shunted by a condenser and connected across the main electrodes to produce a high-voltage impulse. Specification 544,619 is referred to.

Title: Improvements in and relating to regenerative furnaces
IPC: F23L15/02
Filed: 1930-01-03
Abstract: 338,788. Reiner, O. Jan. 10, 1929, [Convention date]. Valves, reversing. - In cowl reversing gear particularly for Martin furnaces, to prevent loss of gas during reversal, a damper in the gas supply pipe is operated from the driving mechanism of the reversing gear in such a manner that it is closed with a jerk immediately before the cowl leaves the water seal and opened with a jerk immediately after the cowl has re-entered. the water seal. The cowl 6 spans two of the flues 5, 7, 4 and takes into a hydraulic seal S into which the casing 3 also depends. Parallel links 11 carry the cowl and, are connected to a sector 10 meshing with a rack 9 on a reversing rod 8. From the rack 9 extends a bar 13 which operates quick-action mechanism to open and close the damper 12 in the gas supply pipe 1. The bar 13 moves a slide 14 having arms 15 connected by a rod 16 on which slides freely a finger 17 integral with a rack 18 meshing with a pinion 21 on the shaft 23 of the damper 12. Springs 19, 20 extend between the arms 15 and the finger 17. A disc 22 fixed to the shaft 23 of the damper has three notches 24 arranged at angles of 90‹ into one of which takes a latch 26 on a slide 27 movable at right angles to the slide J4 and acted on by a compression spring 32. A pawl 28 is pivoted on the slide 27 and adapted to co-operate with detents 29, 30 on the slide 14, rocking movement of the pawl being limited by stops 31. As shown in Figs. 1 and 4, the damper 12 is open and gas flows in the direction of the arrow C while the cowl connects the regenerator passage 5 with the chimney flue 7. When the rod 8 is moved to the left, the slide 14 moves in the same direction, and before the cowl 6 leaves the seal the detent 30 has moved the pawl 28 into contact with the right-hand stop 31. On further movement of the slide 14 the slide 27 is displaced by the detent 30 and lifts the latch 26 out of the disc 22. The spring 16 being now compressed moves the rack 18 to the left by the finger 17 and the disc 22 is rotated through 90‹ until the latch 26 enters the left-hand notch 24; the damper 12 is thus closed, Fig. 5. Continued movement of the rod 8 raises the cowl from the seal and moves it to cover the flues 7, 4; immediately after the cowl' reenters the seal the detent 29 moves the pawl 28 into contact with the right-hand stop 31 and releases the disc 22 so that the damper 12 is opened by the spring 20 which has meanwhile become compressed, and the latch 26 enters the right-hand notch 24. On return of the cowl to the position shown in Fig. 1, the detent 29 first engages the pawl 28 and the left-hand stop 31 is utilized. A gas regulating valve is provided on the casing 3.

IPC: F01M1/06
Filed: 1917-01-15
Abstract: 109,913. Pullin, c. G. Jan. 15, 1917. Force-feed Lubricating.-Oil is supplied by a pump to the surface of an internal-combustion engine piston during its inward stroke, and during the return stroke oil is scraped from the cylinder wall and delivered to a discharge opening. The invention is particularly applicable to a piston made of aluminium. During the inward stroke of the piston a radial passage b in the crank, to which oil is pumped through a bore in the crank shaft, registers with a groove K in the connecting-rod bearing, and oil then passes through passages g, h in the connecting rod and gudgeon pin to a passage h in the piston leading to a groove i. On the outward stroke, a sharp-edged piston ring J scrapes oil from the cylinder wall into the groove i, and this oil passes to an outlet formed by openings l, L in the gudgeon pin and small end of the connecting-rod, which have come into register, the connexion between the gudgeon pin and the passage g being cut off by the angular movement of the connecting-rod. Fig. 3 shows a connexion between the pump and the end of the crank shaft, consisting of a spring-pressed washer m on a nozzle U bearing against a plug c. The oil pump D, Fig. 4, has a branch d containing a plunger N in contact with an electric terminal n in the circuit of the magneto. If the oil pressure fails the magneto circuit is broken, stopping the engine.
