Title: New or improved means for controlling electrically actuated clutches
IPC: H02P9/06
Filed: 1947-09-11
Abstract: 635,792. Controlling motor vehicle clutches. HUMBER, Ltd., MILLER, A.C., and BERRY, G. Sept. 11, 1947, No. 24995. [Class 80 (ii)] A motor vehicle electro-magnetic clutch 18, such as described in Specification 594,906, is engaged by a speed-responsive generator 4 at low engine speeds above which a voltage relay 9 transfers the clutch supply to a 12 volt battery 21. The generator output terminal 2 is connected, via the contact 10 of an emergency switch 12, the contact 13 of the relay 9 and the contact 15 of a relay 16, to the clutch winding which has an earth return path. A resistor 22 and a capacitor 23 suppress induced clutch voltages. When stationary but in gear, increasing engine speed increases the generator voltage to 6-12 volts thereby gradually engaging the clutch, whereafter it attains such a value as to cause the coil 8 of the relay 9 to move its armature to a contact 14 thereby connecting the battery 21 to the clutch winding. When changing gear a lever 20, as described in Specification 619,223, engages a contact 19 whereby the coil 17 of the relay 16 is energized thereby causing interruption of the supply to the clutch which becomes dis-engaged until after selection of the next gear. Should the generator fail the clutch may be energized by the battery at all speeds by connecting the blade of the switch 12 to a contact 11. Variation of the predetermined speed at which the clutch engages is effected by opening a switch 5 shorting a resistor 7, connected in the generator field circuit to a conventional cut-out and compensated voltage control regulator 24. In a modification a current relay replaces the voltage relay 9. Specification 610,519 also is referred to.

Title: Improvements in cinematographic apparatus
IPC: G03B1/42
Filed: 1928-09-04
Abstract: 296,728. Oehmichen, E. Sept. 6, 1927, [Convention date]. Kinematograph apparatus. - In apparatus which is not provided with toothed continuousfeed sprockets between the spools and the gate, means are provided to prevent displacement of the film in the gate and excessive tension in the film due to variations in the running of the spools. As shown in Fig. 1, the film 2 from the pay-out spool 6 passes round rollers 8, 9, 10 which are geared together and are driven by the projector to have a peripheral speed slightly greater than the mean speed of the film through the gate. The rollers 8, 9 have fixed spindles, but the spindle of the roller 10 is carried by an arm 13 pivoted about the spindle of the roller 9 and supported by a spring 14. Shortening of the film loops around the rollers causes the film to engage the rollers tightly and to be drawn from the spool at an increased speed. The film passing to the take-up spool 7 may pass round stationary friction members 21, 22, 23, or around members which, although not fixed, serve to reduce the velocity of the film. Fig. 2 shows a modification wherein the film passes round roller? 29, 30, 31, the spindle of the roller 30 being. carried by a pivoted arm 32 acted upon by a spring 34. The arm 32 is connected by a cord 59 to a brake band 58 engaging a drum 56 carrying the planet pinions 57 of a differential gear in a driving connection for the pay-out spool 28. Shortening of the film loops round the rollers causes the brake band to be operative and the drive for the spool to be effective. A subsidiary loop in the film between the roller 31 and the gate may be formed by air supplied from a nozzle 62 or by a weak spring. Similar means may be provided between the gate and the take-up spool 35, the cord 71 being arranged to cause the brake band 70 to be effective when the film loops enlarge. Specifications 305,550, 305,776 and 307,270 are referred to.

Abstract: 1395346 Ammonium nitrate MISSISSIPPI CHEMICAL CORP 2 June 1972 [11 June 1971] 25945/72 Heading C1A [Also in Division B1] A thermal siphon-pressure pump neutralizer for neutralizing nitric acid with ammonia comprises a reaction vessel 2 suitable for containing an aqueous reaction medium and having a vapour outlet 23, and product outlet 27 defining the level of the aqueous reaction medium in the vessel; an elongated fluid impervious cylindrical member 10 positioned within the vessel so as to define a second reaction zone 11 within the member and a first reaction zone 5 outside the member, the member having an inlet 9 and an outlet 12 and being situated such that when the vessel contains an aqueous reaction medium, the member inlet will be beneath the level of the medium in the first reaction zone, and the member outlet will be above the level of the medium; ammonia inlet means 15 for introducing ammonia and/or ammonium hydroxide into the reactor vessel in proximity to the cylindrical member inlet 9 and in the direction of the inlet; and nitric acid inlet means 3 situated between the product outlet and the inlet of the cylindrical member. Nitric acid is introduced in amounts such that the concentration of the nitric acid entering the second reaction zone will be less than 15%, so that the major portion of the nitric acid will be neutralized with the ammonia at the said dilute concentration within the second reaction zone, and whereby the heat of neutralization and differential density will promote circulation of the reaction medium between the first and second reaction zones, and the water vapourized by the heat of neutralization will be discharged through the vapour outlet 23 and ammonium nitrate product will be recovered through the product outlet 27. The rate of circulation between the first and second reaction zones may be increased by spacing the ammonia inlet 15 and 16 and the second reaction zone inlet 9 so that a constriction X creates a venturi-like effect. A curvilinear deflector 21 supported above the cylindrical member outlet deflects the solution fountaining from the member downwardly back to the first reaction zone and vapours emitted from the member outlet circumvent the deflector and pass through the vapour outlet.
