Title: Room-heating process using hot air and installation for carrying such process into effect
IPC: F24F13/15
Filed: 1952-03-27
Abstract: 734,681. Measuring heat quantities. SOC. POUR L'EXPLOITATION DES PROCEDES C. STRACK ET L. MAUNY. March 27, 1952 [March 27, 1951; March 24, 1952], No. 7924/52. Class 97 (3). [Also in Groups X, XIII and XXXV] In a system (see Group X) for heating a building, hot air is passed from controlled outlets of a main distribution shaft, each outlet communicating with a corridor of one of a number of flats. A thermostat 56 in each corridor may control the motor of a fan, Fig. 12 (not shown), in each outlet and the current consumed by the fan in supplying hot air to the flat may be measured to indicate the heat consumption. In another method, Fig. 16, the outlet is controlled by a damper arrangement and a thermostat 56 regulates the current in two resistances 85 which each heat a bimetallic strip 84 (one shown), attached to an end of one of two slotted plates 80, forming the damper and sliding over each other to operate on a hit-and-miss principle. A meter 96 is connected in parallel with the heaters 85 in a circuit containing parallel resistances 92 adjustable manually by a slider 94 and cut in or out automatically by a mercury thermometer 90 in the circuit and located outside the building. When electricity is supplied to heat the bimetallic strips 84 and allow hot air to enter the flat corridor from the shaft, the current is measured to indicate the heat used. The thermometer 90 introduces a factor depending upon the amount of heat supplied to bring the air up to temperature.

Filed: 1925-03-24
Abstract: 244,695. Sullivan Machinery Co., (Assignees of Holmes, M. P.). Dec. 19, 1924, [Convention date]. Coal-cutting machines.-A mining-machine has a feed operating member arranged on a longitudinal axis and driven through change-speed mechanism including planetary gearing. A reversible or uni-directional motor drives a pinion 15 which drives a shaft 24 by fast and slow gearing which may be arranged to give the same direction of drive at both speeds or opposite directions. The shaft 24 carries a pinion 43 engaging pinions 44 which engage a stationary internal gear 54 and are carried by a spider 47 on a shaft 48, which is thereby rotated. The feed drum 8, or feed sprocket, is keyed to an externally-toothed clutch member 58 adapted to be connected by a sliding internally-toothed member 57 to a similar clutch member 56 keyed to the shaft 48, whereby the feed drum &c. is driven. For transport purposes the machine may be mounted on a truck and the member 93 of the driving-gearing of the truck may then be connected to the clutch member 56 by the sliding member 57. Guide rolls or sprockets 84, 85, Fig. 11, are provided on each side of the machine, and additional guides 91, coaxial with the guides 84, 85 may also be provided.

Title: Improvements relating to distance fuel gauge for automobile vehicles
IPC: G01F23/32
Filed: 1928-03-15
Abstract: 298,149. Ateliers Seignol. Oct. 4, 1927, [Convention date]. Indicators actuated by floats.-A liquid level indicator particularly applicable to fuel tanks of motor vehicles comprises a float 1 carried by a rod 2 pivoted at 3 to a slider 4 moving on a vertical rod 5 carried by a cap 6. One end of the rod 2 is pivoted to a connecting rod 8 which is pivoted to a fixed point on the guide rod. The movements of the slider 4 are proportional to those of the float, and are transmitted to an indicating device by a cord 7 passing through a guide 9. The rod 2 is a strip of metal bent as shown in Fig. 2, so that any agitation of the fuel causes it to yield laterally and the slider is thus pressed on the guide and irregular movements of the cord 7 are prevented.

Title: Means for controlling undesired reflections in optical apparatus
IPC: G02B27/10
Filed: 1933-03-17
Abstract: 416,509. Optical apparatus. HILGER, Ltd., A., and DOWELL, J. H., 98, King's Road, Camden Road, London. March 17, 1933, No. 8147. [Class 97 (i).] In order to prevent disturbances due to undesired reflection of light from the boundary or partition surfaces of optical elements or apparatus, any such surface is divided into a number of steps inclined at an appreciable angle to the direction of the light path and having sharp angles towards the said path, so that stray light impinging on the surface is reflected in a direction substantially different from that of the useful light. Figs. 1 and 2 show a Nicol prism in which each boundary surface is formed as a series of steps 14 sloping inwardly in the direction of the light path and having sharp edges 16 towards the said path. Stray light is reflected by these steps as shown by the arrows 12, 13, the direction of the useful light being shown by the arrow 11. Figs. 5 and 6 show a reflecting prism as used in binocular telescopes ; each side face is divided into two sets of steps parallel to the entrance and exit surface and sloping in opposite directions, the two sets being separated by an inclined face 19. Alternatively, in such a prism, the two sets of steps may be parallel to the two reflecting surfaces. In a two-colour system using a split lens and a dividing plate between the part lenses, the inner surfaces of the lenses may be stepped as above described, and the plate may also be stepped, the steps on the plate being inclined outwards in the direction of travel of the light and fitting corresponding steps of the lens. The interior walls of optical instruments may be treated in a similar manner. Specifications 346,406, 349,107, and 394,385 are referred to.

Title: Improvements in couplings

IPC: B61G3/18
Filed: 1960-03-08
Abstract: 885,012. Coupling lock arrangements. HILGER, O., BUSCH, W., and FRIEDERICHS, H., [trading as BERGISCHE STAHLINDUSTRIE REMSCHEID]. March 8, 1960, No. 8150/60. Class 103(5). A vehicle coupling is provided with a locking bolt 13 eccentrically mounted in a rotatable bushing 12 so that axial movement of the bolt during coupling produces a rotational movement on the bushing which automatically adjusts for wear between interengaging bolt faces 24 of mating couplers. The bushing 12 has a centre of rotation M and is rotatably mounted in the coupling 11 but is limited in its movement by a pin 22 extending from the casing and engaging a slot 21 in the bushing. The bolt 13 having a centre m is pressed outwardly thereof by compression springs 14, 15, and a tension spring 16 acts through a bolt 17, yoke 18, and pins 19 to keep the bushing pressed against a collar 20 on the member 13. A rotatable cam 23 is provided to push back the lock for uncoupling. In operation, when the bolt faces 26 of two unworn couplers abut one another the bolt 13 of each coupler is forced completely inwardly to the Fig. 3 position where locking surfaces 24 lie in the same plane as butt faces 25 on the couplers. In this position the bolts may reach behind and engage one another. The springs 14, 15 now push the bolts 13 forwardly to the locking position and the spring 16 forces the bush 12 in the direction Z and turns it so as to cause the surfaces 24 to approach and abut one another and take up wear to a maximum distance X, Fig. 5. In a modification the bolt collar 20, spring 16, and the pin 22 are omitted, and a slot similar to 21 is provided on the inside of the bushing 12. A spring coiled around the bolt is provided between the bolt and the bushing, one end of the spring being fixed to the bolt and the other end carrying a pin sliding in the slot. The bush is rotatably mounted in the casing but is restrained from moving axially.

Abstract: 1,163,405. Reducing iron ore. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Feb.15, 1967 [Feb.24, 1966], No.8221/66. Heading C7D. Iron ore and fluxing agents are introduced into a furnace together with a carbonaceous material and an oxidant whereby the ore is melted and reduced. The carbonaceous material is added to the slag layer, while a part of the oxidant is also introduced into that layer but at a level below that of the carbonaceous material, whereby a controlled oxygen potential gradient is maintained in the slag layer through which the metal falls. The remainder of the oxidant is introduced above the bath level to burn the gases evolved and provide heat for the reaction, while the gases leaving the furnace may be used to pre-reduce the ore, and/or with or without combustion to pre-heat the raw materials. The carbonaceous material may be solid, liquid or gaseous but by using a gaseous hydrocarbon the reduction of impurities from the ore is minimized. Suitable fluxes are lime, dolomute, silica or felspar, while the oxidant introduced into the slag layer may include oxides of iron.
