Title: Improvements in or relating to apparatus for extinguishing cigarette ends and the like
IPC: A24F19/14
Filed: 1936-12-31
Abstract: 468,541. Cigarette &c. extinguishers. CUTLER, S. Dec. 31, 1936, No. 22866. [Class 130] In an extinguisher of the type comprising a relatively rotatable chambered member 15 and cover 11, ratchet mechanism is provided to ensure that relative movement between the member 15 and the cover takes place in one direction only. In the form shown, the members 15 is cylindrical and is mounted on the upper end 20 of a vertical rod 13 mounted centrally in an ash-tray 12. A cylindrical cover 11 rotatable about the member 15 is provided with upper and lower openings 23, 32 adapted to register in turn with extinguishing bores 16-18 in the member 15. To ensure that the cover 11 may be rotated in a clockwise direction only, the member 15 is provided with a spring-pressed ball 33 and a ratchet detent 35 co-operating with apertures 39-41 in the cover. On turning the cover, each of the bores 16-18 is successively opened at 23 to admit a cigarette end &c., closed to extinguish it, and opened at 32 to discharge it. In a modification, a vaned member is rotatable about a horizontal axis in a fixed cylindrical cover by means of a lever provided with a pawl acting upon a ratchet wheel on the end of the vaned member. British Specification 422,133 and U.S.A. Specification 1,912,598 are referred to.

Title: Fluid supply apparatus
IPC: F15B11/08
Filed: 1973-05-14
Abstract: 1380226 Hydraulic control circuits POCLAIN 14 May 1973 [31 May 1972] 22905/73 Heading F1P In the circuit shown in Fig. 1, when a valve 13 is moved to the left fluid flows through a line 17, and a check-valve 18 to raise a piston 2 and a load 7. When the valve is moved to the right fluid is delivered through a line 16 to a chamber 4 to push the piston down, assisted by the load 7. Fluid from chamber 5 returns to a reservoir 11 through a flow limiter 19 which prevents cavitation in the chamber 4. In the flow limiter 19, Fig. 2, fluid from chamber 5 and line 20 arrives opposite a shoulder 29 of a slide 20. The position of the slide 20 is determined by the balance between pressure in the line 16 which tends to move the slide to the right against a spring 33, and pressure in the conduit 20, caused by an adjustable throttle 22, which tends to move the slide to the left. Thus, when the load is tending to over-run the fluid supply, the pressure in line 16 is low and the slide moves to the left to throttle the return line. Fig. 3 (not shown), illustrates a modified construction of the slide 20 which damps the movement thereof.

All the asynchronous motors are connected to a mains supply (unreferenced) through respective ones of the contacts of switches 12, 16; 19, 22 and 23, the other ones of these switch contacts connecting the synchronous motors to the output of a conventional variable frequency generator 14 whose input is connected to the mains supply. The rollers 1, 1<SP>1</SP> are driven by a common synchronous motor 5 through a gear 27 and electro-magnetically operable couplings 24, 25, 29, each receiving the same power supply as the asynchronous motors. 3 in the zone including the respective coupling. In a typical starting operation, the contacts of switches 12, 16 are simultaneously closed to energize the motors of zone I and the motor 5, which are operated at a creeping speed. When the switch-on current surge has subsided, the contacts of switch 19 are closed to energize the motors of zone II and the coupling 2.5, subsequent actuation of switches 21, 23 energizing the motors of zones III and IV and the couplings 29, 24. When all the zones are operating at a creeping speed, the generator 14 is adjusted to accelerate the motors up to their normal operating speed. Switches 12, 16; 19, 21 and 23 may be manually or automatically operable.

Abstract: 674,801. Magnetic toys. SEIDEL, B., HAMANN, G., and MULLER, K. H., (trading as SEIDEL, M.). Sept. 19, 1950 [Sept. 20, 1949], No. 23024/50. Class 132 (iii). A toy comprises a model which is movable on a surface by means of a magnet movable underneath the surface. In Figs. 1, 2, a vehicle 5 carrying a magnet runs on a surface 2 e.g. of zinc or aluminium and is controlled from a panel 40 of a housing 1. An electric motor 6 in the housing has a speed and reverse control 8, and, through gearing 10, 11, 13, 14 drives a spindle 15 carrying a revolving arm 16 on which is mounted a carriage 18 carrying a magnet 20. A pulley 22 revolves by friction with the spindle 15, and the carriage 18, positioned longitudinally on the arm 16 by a rope drive 21, thus remains at a constant radial distance from the spindle unless a steering wheel 34, which is normally disengaged from gearing connected to the pulley, is operated. The vehicle may thus be "steered" in its circling movement to avoid obstacles 3, 4 on the surface 2. Controls and indicators also comprise a signal lamp, horn, starter, mileage indicator, or speedometer. The signal lamp 38 may be made to operate when the obstacles 3, 4, are struck by the vehicle.

The object is to prevent failure of the sensor resulting in a dangerously lean mixture. Five alternative transistor circuits are described, Figs. 2 ... 6, (not shown) for the device 16, all of which feature an output transistor which is made non-conducting, and so raises the voltage on the output terminal to maximum (it normally is proportional to the input), when the input is short or open-circuited. The output of 16 is compared with a reference at 20 and adjust the air/fuel ratio via proportional 21 and integral 22 amplifiers.
