Title: New or improved instrument or apparatus for indicating the rate of flow or consumption of liquids, such as liquid fuel
IPC: G01F9/00
Filed: 1921-11-14
Abstract: 193,123. Mitchell, W. B. Nov. 14, 1921. Liquid-fuel-consumption rate indicators.- Comprises apparatus for giving an indication of the rate of consumption of liquid fuel, for example, in a motor vehicle the number of miles per gallon, or, in a motor vehicle, stationary engine or motor boat, the number of revolutions per unit of fuel or, in oil furnace steam ships, the number of nautical miles per unit of fuel. The fuel is admitted to a chamber intermediate between the reservoir and the place of consumption, under control of means driven either by a road or similar wheel when the instrument is calibrated for distances per unit of fuel, or directly from the engine when calibrated for revolution per unit. A cam u on a shaft t driven from the road wheel or engine reciprocates a piston o against a spring p in a barrel g which communicates with the fuel reservoir and chamber a through ports k and l respectively. A float b in the chamber a carries a rack y meshing with a pinion z to move a pointer over a graduated scale x and a wedge cam 1 coacting with a slot v in the piston rod q. The frequency of the pump is thus determined by the speed of the shaft t and its stroke by the height of liquid in the chamber a which also determines the position of the pointer and which is, moreover, determined by the relative rates of supply and withdrawal of fuel therefrom. Modifications are described involving the use of differently shaped cams and dispensing with the toothed rack. In these constructions, moreover, the pump draws fuel from the reservoir at each alternate stroke but delivers it to the chamber a at each stroke.

Title: An electro-magnetic system for starting internal combustion engines
IPC: F02N11/08
Filed: 1924-12-19
Abstract: 240,682. Fornaca, G. Dec. 19, 1924. Starting prime-movers.-An internal-combustion engine is started by an electric motor 9, the pinior. 13 of which is moved by a solenoid 7 into engagement with the rim 14 of the engine to be started, while the motor 9 is fed through a resistance 10 so as to rotate at a slow speed, the resistance 10 being short-circuited when the pinion and rim mesh, and finally when the engine is started the solenoid 7 is de-energized. Closure of a double-pole switch 6 completes two circuits, one from the battery 1 through the armature 4 of a battery-charging dynamo, the switch 6 and solenoid 7 to earth M<2>, the other from the battery through the resistance 10 and armature 9 to earth M<3>. When pinion 13 and rim 14 mesh, switch 19 is closed and short-circuits the resistance 10 so that the motor runs at full speed. When the engine has started the dynamo 4 excites and its cut-out 5 closes, thereby shorting the solenoid 7 between earths M<2>, M<1>, so that the pinion is retracted by a spring 17 even though the switch 6 remains closed, and the solenoid cannot be reenergized as long as the cut-out 5 remains closed. The pinion 13 is carried by a shaft 12 slidably keyed within the hollow armature shaft 11, a compression spring 18 being interposed between the shaft 12 and the core of the solenoid 7.

Title: An electroacoustical horn

Filed: 1970-06-24
Abstract: 1,273,690. Electroacoustical horns. D. FRIGO. 24 June, 1970, No. 30699/70. Heading G5J. An electroacoustical horn comprises a permanent magnet 35, which provides a magnetic field having lines of flux extending radially with respect to a cylindrical coil 16. The coil 16 is series connected to a pair of normally closed contacts 17, 21; the contact 21 being fixed, and the contact 17 being movable. The contact 17 is connected to a conductive resilient arm 18 which is connected to the windings of the coil 16 by means of a rivet 19. The permanent magnet 35 is held inside an inverted cup 34 of ferromagnetic material, which is made fast with a ferromagnetic block 33, a stem 32 and the diaphragm 14. When current flows through the coil, the permanent magnet experiences a downward force, thus moving the block 33 and stem 32 which urges the resilient arm 18 downward and causing the movable contact 17 away from the fixed contact 21. The current thus stops, and due to the resiliency of the diaphragm, the assembly moves back to its initial position and the process repeats. Sound, produced by the diaphragm 14 is passed into a trumpet 13. The position of the fixed contact can be altered by means of a screw (not shown). In an alternative arrangement, the magnet may be connected to the case, and the coil to the diaphragm.

Convention dates, Nov. 25, 1938 and Oct. 19, 1939. [Class 2 (iii)] Hydroaromatic compounds are obtained by condensing compounds containing a system of conjugated double linkages of which at least one multiple linkage is non-aromatic with 1 : 2-diacyl ethylene compounds or 1 : 2-diacylacetylene compounds. Suitable conjugated compounds mentioned include butadiene and its derivatives and vinyl substituted naphthalene compounds. Reaction partners which are mentioned include 1 : 2-diacetyl ethylene ; l:diacetyl propylene; 1 : 2 - diacetyl butylene; 1-acetyl-2-formyl ethylene and 1 : 2-diacetyl acetylene. Condensation products of the invention may if desired be subjected to a further hydrogenating or cyclizing reactors. In examples (1) 1 : 2-diacetyl ethylene and 2:3- dimethyl-butadiene-(1 : 3) are refluxed in benzene solution to give 1 : 2-diacetyl-4 5-dimethyl-cyclohexene-(4). This compound is subjected to a cyclizing treatment with 0 - 1 N sodium methylate solution to give 1:5:6- trimethyl 4:9:7: 8-tetrahydro-indone-(3). Iristead of a simple butadiene there may be used a #<SP>1À2</SP>-1-ethenyl-, or ethinyl-polyhydronophthalene, in which case a cyclopentanopolyhydrophenanthrene compound is obtained. (2) a benzene solution of 1-vinyl-6-methoxy-3 : 4- dihydronaphthalene and diacetyl acetylene is refluxed for 48 hours to give a condensation product which melts at 174‹-175‹C. together with a small amount of an isomeric product which may also be isolated. Both condensation products yield the same dihydro-product which is 1 : 2 - diacetyl - 7 - methoxy 1: 2 : 3 : 4 : 9 : 10 : 11 : 12-octahydro-phenanthrene. (3) The condensation product of example (2) melting at 174‹-175‹C. is cyclized with 0: 1 N sodium methylate solution in methanol. (4) The hydrogenated product obtained in example (2) is cyclized by treatment with sodium methylate as described in example 3. '

Amphoteric metals, such as Ti, V, Cb, Ta, Cr, Mo, W, Mn and Fe, and alloys thereof are produced by reducing sulphides, tellurides, oxides and other O- containing compounds of such metals with Li metal in the liquid or vapour phase in the absence of O, N, H, CO 2  or other gas which would react with the Li. The Li may be alloyed with Na and K, and the reduction may be carried out in the presence of argon or other inert gas. Excess Li, Li 2 O and many impurities such as N, S, H and Cl may be removed by leaching. As shown in Fig. 1, the charge 31 surrounds a thermocouple 33 in a steel pan 32 placed at the inner end of a retort 15 which is heated by a furnace 10 with heating elements 19 and a thermocouple 34. An extension 24 of the retort is fitted with a removable head 26 carrying a sight glass 27, water cooling chambers 28 and an opening 30 connected to an evacuation pump and a source of inert gas.

Abstract: 812,996. Automatic control systems for cameras. REVERE CAMERA CO. Oct. 16, 1956 [Aug. 23, 1956No. 31447/56. Class 38 (4). [Also in Groups XX and XL (b)] A camera lens system comprises a photoelectric device connected to a meter, powerdriven means for mechanically sensing the position of the meter needle and controlling the electrical input of the meter whereby the lens aperture is controlled. In a movie camera, Fig. 3, a lens 20 focuses light on to a photo voltaic cell 30, the current from which deflects needle 36 of a meter 35 to either side of a worm. The knife edges of plungers 40, Fig. 4, are reciprocated within slots on either side of the needle 36 by a pivoted bell crank 51 driven by the spring motor and pivoted to the yoke 50. When the needle is at normal (i.e. correct exposure) it is not engaged by the plungers. Upon deflection one of the plungers is engaged and the other overdriven upwards so that its pawl 60 or 61 engages ratchet 62 or 63 to drive shaft 64 which, through gears, Fig. 3, opens or closes the irises of the camera (24) and meter 23, which operation continues until the needle returns to normal. The needle may be clamped during each sensing movement either by a third plunger (Fig. 9, not shown) or by movement of the plates enclosing the needle. In a still camera a pivotable mirror may focus light from the camera lens on to the photo-cell (disposing with a separate meter lens) and adjustment of the aperture may be manual.
