Filed: 1974-06-18
Abstract: 1460181 Spray producers STERN FRERES SA 18 June 1974 [20 June 1973] 27047/74 Heading B2F A mist generator, for humidifying air, comprises a vessel 7 charged with liquid to a predetermined level L, the liquid level being maintained by means of an inverted bottle feeder 1-5 and liquid being supplied to the vessel via a conduit 6, a piezoelectric transducer 8 fed with ultrasonic alternating current from a source S controlled by a controller 9 being focused at the liquid surface in order to produce a cloud of mist, the mist cloud being ejected through a nozzle 10 by means of the inward movement of a deflectable wall 11 in the form of an elastic membrane reciprocated by a rod 12 slidable in a fixed yoke 13. The rod 12 is urged outwardly by a spring 14, and is actuated by a pivoted rod 15 and a cam 17 carried on the shaft 18 of an electric motor 19 coupled to the controller 9. The arrangement is such that the transducer 8 is operated for a predetermined time to produce a mist cloud, and thereafter the wall 11 is deflected for a slightly greater time to expel the mist cloud through the nozzle 10. A humidistat may be coupled to the controller 9 to cycle the mist generator until the mist content of the surrounding air reaches a predetermined value. In a modification, Figure 2 (not shown), an additional cam (20) on the motor shaft 18 and a cooperating switch (21) perform the function of the controller, such an arrangement being intended for continuous operation. In the modification of Figure 3 (not shown) the sliding rod and yoke arrangement is replaced by a fast-acting solenoid (23) deflecting the wall (11') via an attached plate (24). In order to prevent the rapid action of solenoid (23) from sucking the expelled mist back into the vessel (7'), the vessel is divided by a partition (27) above the liquid level L into two compartments (25), (26), one-way flap valves (29) and (31) being provided respectively in the partition (27) and in the wall of the compartment (26) to allow ingress of air into compartment (26) on the return stroke of the solenoid and expulsion of air from compartment (26) to (25) and thence to nozzle 10 on the pumping stroke of the solenoid.

Abstract: 1517117 I C engine combustion chambers FORD MOTOR CO Ltd 2 July 1976 27610/76 Heading F1B In an I.C. engine, a ridge 26 on the piston crown co-operates with a step 24 on the cylinder head to divide the combustion chamber into sub-chambers 28, 30 at and near t.d.c., the sub-chamber 30 being of smaller volume than the sub-chamber 28 so that charge is forced through a gap 32 between ridge 26 and step 24 into sub-chamber 28 to cause turbulence therein. The face of ridge 26 within subchamber 28 is concave as shown in Fig. 3. In the case of spark ignition engines, combustion may be initiated in sub-chamber 28, i.e. by spark-plug 34, spreading subsequently to sub-chamber 30, the turbulence in sub-chamber 28 enabling a lean mixture to be used. If combustion is initiated in chamber 30, i.e. by spark-plug 36, initial combustion is moderate while the sub-chambers are separate, spreading rapidly through the turbulent charge within sub-chamber 28 when the chambers are open to each other, the mixture being within a range from stoichiometric to moderately lean. Fuel may be directed towards sub-chamber 30 by injector 38 giving a rich mixture within this subchamber for initial ignition by spark-plug 36 and a lean main charge in sub-chamber 28. The commencement time of fuel injection may be variable to give an injection period proportional to load, intake air being unthrottled. Alternatively, the air supply may be throttled and the fuel injection period varied in accordance with air-flow. In the case of a compression ignition engine, fuel is injected into chamber 28 near t.d.c.

[Class 9 (ii)] [Also in Group XI] Relates to a flash-light lamp, more particularly for photographic purposes, in which a light generator of easily inflammable sheet or wire form is disposed in a hermetically closed glass vessel containing oxygen. According to the invention, an oxygen filling or charge at atmospheric pressure or higher is employed, the number in cubic centimetres representing the space in the preferably tubular vessel being not greater than the number representing the weight of the light generator in milligrams. As shown in Fig. 1, the lamp consists of a cylindrical glass vessel 1 having a content of 40 ccms. and in which is inserted a bundle of aluminium or magnesium sheet 3 weighing 40 mg. This vessel is closed at its lower end by melting in a glass bead 4 through which pass the current leads 5, 6 which carry the ignition wire 8 covered with an ignition pellet 7. A socket 10 is cemented in known manner on the neck 9 of the vessel 1. If desired, each end of the vessel may be closed by means of a glass bead. Fig. 3 shows a modified construction of lamp comprising a metallic screw-threaded sleeve 11, an insulating body 12 and a metallic bottom contact plate 13. The leads 5, 6 carrying the ignition wire 8 and pellet 7 are fused into a glass bead 4, the end of the wire 5 being soldered to the plate 13 whilst the end of the wire 6 is soldered to the sleeve 11. The pellet 7, wire 8, leads 5, 6 and socket 11, 12, 13 thus form a unit which is partially filled with a cement 14. The open end of the vessel 1 containing the foil 3 and oxygen charge is pressed into the socket whilst the cement is in a plastic condition, the cement eventually hardening to form a vacuum-tight closure of the body 1. According to a further modification, Fig. 4 (not shown), the bead 4 is dispensed with, the lower end of the vessel 1 is threaded so as to screw into the socket 11 and a fusible wire enclosed in a small glass tube is inserted in one of the leads 5, 6. The body 1, which may be provided with an external or internal coating to prevent danger of shattering, may consist of coloured glass or glass allowing the passage of ultra-violet rays. Instead of providing an electrically ignited pellet 7, the foil &c. 3 may be ignited by a frictionally produced spark or bv the introduction into the vessel 1 of a chemical reacting with the oxygen charge and forming a flame, said chemical being initially enclosed in a small chamber in the vessel 1.

Abstract: 158,967. Barnett, C..J. Nov. 8, 1919. Switches, quick-action. - In an electricallydriven phonograph &c., automatic means for starting the motor by movement of the tone-arm and/or means for stopping the motor when a desired point on the record is reached, together with means for illuminating the record, comprises the combination with a switch to control the connection of the driving motor with the supply circuit and a trigger which holds up the switch against a spring or other controlling means until tripped by movement of the tone-arm, of a friction drum formed on or operatively connected to the tone-arm and a friction band on said drum having a projection to engage the trigger and operate it at a desired point. When the lid 33 is opened, the tone-arm being over the last groove of the record, a rod 29 connected to a bell-crank lever 26 moves upward's under the action of a spring 27, the lever 26 pressing a stop 28 on a pivoted arm 16 against a weaker spring 17 until a horizontal portion of the rod 29 engages the bearing 30. This moves the contact-member 40 of a switch 35 into the position shown in Fig. 2 in which the metal contact 41 short-circuits the motor 3 and connects the lamp 44 directly to the supply mains. The tone-arm 9 is mounted on a hollow spindle 11 carrying a drum 12 with friction band 13 having projections 14 and 18. A second spindle 22 is rotated by means of a milled head 23 until its lower end 24 bent upward at 25 engages with the projection 14 thus pressing a trigger 19 against an adjustable stop 21. The tone-arm is then moved to the commencement of the record, during which rotation the projection 18 moves the cranked lower end of the lever 16 into the position shown in Fig. 1 in which the motor is connected in series with the lamp and starts up. In this position the trigger 19 moves under its spring 19<a> until its upper end rests against the stop 20 and holds up the lever 16 against its spring 17. The case is then closed and the projection 34 on the lid depresses the rod 29 freeing the lever 26 from the stop 28. As the tone-arm moves across the record the projection 14 moves the trigger towards its stop 21 until its end is clear of the stop 20 when the contact member 40 breaks contact with the switch and the motor and lamp are disconnected. Specifications 138,994 and 160,394, [Class 40 (ii), Phonographs &c.], are referred to.
