Inventor: KITCHEN JOHN GEORGE AULSEBROOK
IPC: F02M31/18
Filed: 1916-05-19
Abstract: 104,096. Kitchen, J. G. A., and Storey, I. H. May 19, 1916. Vaporizers, external.-The apparatus is of the kind described in Specification 10345/13, in which vapour generated in a vaporizer 1 issues from a nozzle 19 in the air-pipe 7. The warming of the air before it mixes with the vapour is dispensed with, but the nozzle 19 is insulated from the air-pipe by a non-conductor of heat 36. Unvaporized and condensed fuel is arrested by a plate 26 and falls into a sump 24, whence it is withdrawn and discharged into the reservoir 3 by a pump 29, which also serves to keep up the air pressure in the oil reservoir 3. The air valve 10 and the vapour valve 16 are geared together by adjustable spur gearing 12. The pipe 5 leads to the vaporizing coil, and the pipe 6 to the burner. The branches 9 of the induction pipe 8 lead to four cylinders.

Abstract: 756,982. Reversing gear. SINCLAIR, H. Feb. 28. 1955 [March 12, 1954], No. 7350/54. Class 80(2) The runner 11 of a hydraulic coupling A is connected through gearing 12 ... 15 to drive in one direction a shaft 16 such as a ship's propeller shaft and the runner 8 of another coupling B is connected through gearing 9, 17, 19, 15 to the shaft 16 to drive it in the opposite direction. The impellers 1, 4 of the couplings are rigidly fixed to a driving shaft 6 of e.g. a ship's turbine. To reverse the direction of rotation of the shaft 16 one coupling is filled while the other is emptied by moving a scoop tube 20 the ends of which are oppositely directed and located in the coupling cases 3. 5. To prevent backward rotation of the shaft 6 and to damp its motion when reversing a member 22 with teeth 23 is helically splined to the shaft 6 and has pawls 24 engageable with teeth 25 on a fixed member 26. Upon slight backward movement of the shaft 6 the member 22 is moved to the right due to the helical splines so that the teeth 23 engage the teeth 25. When the shaft is rotating in the new direction the teeth 23, 25 disengage automatically. The pawls 24 may be weighted so that they engage the teeth 25 only at low speeds. In a modification the member 26 comprises a worm wheel and forms part of an inching gear for the shaft 6.

Abstract: 685,098. Rectifying; charging and discharging batteries; substituting electricity supply sources in service; automatic regulation. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 2, 1951 [April 5, 1950], No. 7563/51. Classes 38 (ii) and 38 (iv). A vectifer system for supplying a load 6, e.g. a telephone exchange, and for charging a standby battery 3 floating across the load 6, comprises a main rectifier 1 having a voltagecurrent characteristic substantially constant at normal loads and preferably declining at higher loads, serially connected in like sense with an auxiliary rectifier 2 having a declining characteristic at low loads, and is characterised by the load 6 being connected across the main but not the auxiliary rectifier, and by the connection across the auxiliary rectifier of the parallel arrangement of at least one counter-cell 7 and a short-circuiting switch 8 therefor. This arrangement provides for substantially constant load voltage 10 at all loads, apart possibly from current and voltage restriction at high loads, and for the charging of the battery to a higher voltage, curve 9, at low loads, the maximum value of which voltage occurs at points 27, 24, determined by the number of counter-cells 7 in circuit, two and three cells respectively having characteristic curves 26, 19 which at their intersections with the auxiliary rectifier characteristic curve 9 yields such points. One or more relays 8, manually or automatically controlled, short-circuit the cells wholly or progressively with increasing load current as the voltage falls down the curve 9. The opening of a switch 28 in series with the counter-cells permits the battery to be charged to a higher value than that restricted by the counter-cells. Specification 612,852 is referred to.

Title: Improvements in or relating to iris diaphragm setting devices for photographic and cinematographic apparatus
IPC: G03B9/07
Filed: 1950-03-28
Abstract: 680,149. Photographic cameras. CORSI T., and FABRICATORE, G. March 28, 1950 [June 7, 1949], No. 7713/50. Classes 97 (i) and 98 (i). An iris diaphragm presetting device having a lens barrel and an iris diaphragm controlled by a ring rotatable around said barrel, includes a stop-pin projecting radially from said barrel and a separate unit comprising a ring freely rotatable on the diaphragm control ring, a lens hood secured to or integral with the unit ring, a rearwardly extending projection on the unit ring, a set-screw for clamping the unit ring to the diaphragm central ring and a referencemark on the unit ring indicating the diaphragm aperture through the reading on a diaphragm scale opposite said mark, the relative positions of said projection and mark being such that when said projection and stop-pin are in contact, the diaphragm aperture corresponds to that indicated by the reading on the diaphragm scale. As shown, an axially slidable lens barrel 2 has projecting therefrom a stop-pin 4 and rotatable therearound an iris diaphragm control ring 3. A ring 5, which has a lens hood 6 attached thereto, fits over ring 3 and may be coupled thereto by a set-screw 9. Ring 5 has a stop-member 8 for engagement with stop-pin 4. In use, ring 5 is rotated until the lug 8 contacts the pin 4 and then ring 3 is rotated alone until the required reading on a diaphragm scale on ring 3 registers with an index on ring 5. When this has been done the diaphragm has been set to the required aperture. Thereafter, ring 5 is clamped to ring 3 by set-screw 9 so that the two rings may rotate together to increase the aperture for focusing purposes. When the exposure is to be made, it is thus only necessary to rotate the rings again until the stop-member 8 contacts stop-pin 4.
