Title: Marine outboard transmission and drive unit for inboard power plants
IPC: B63H20/08
Filed: 1961-04-21
Abstract: 969,857. Rotary dashpots; reverse gear; lubricating. E. P. MORSE. April 21, 1961 [April 22, 1960], No. 14528/61. Headings F2A, F2D and F2S. [Also in Divisions B7 and F1] The casing 31 of an outboard marine propulsion unit (see Division B7) supports the vertical drive shaft 44 so that it may be rotated, about a horizontal transverse axis to lift the propeller unit out of the water and also to change the attitude of the vertical drive shaft with respect to the transom of the boat. A shock absorber is disposed between the casing 31 and the supporting casing 30. The casing 31 is rotated by the shaft 135 having a lobe 136 at one end which moves in an oil-filled chamber defined by the casing 65, plate 146 and abutment face 145. In the normal propulsion position the lob 136 contacts the face 145 and prevents the drive shaft 44 from rotating. Rotation caused by contact with an underwater obstruction is damped by the oil trapped between the lobe 136 and opposite surface 145 which can only escape through the orifice 154. Forward and reverse drive of the propeller is determined by which gear 34 or 35 is coupled to the drive shaft 33 through an oil pressure actuated piston 112 acting against the clutch plates 113 which are keyed to the gear and clutch driving cups 53 or 54. The mating clutch plates and spring carriers 115 of the clutches are splined to the drive shaft 33. Oil is admitted to the clutch pressure chambers 116 from one of two oil passages of the rotary joint 85 and directed through either of the passages 96 or 97 in the shaft 33. For neutral drive both of the clutch pressure chambers 116 drain to the oil sump 72. Oil in the sump 72 of the casing 30, Fig. 8, lubricates the gears 34, 35 and 36. The pump 56 also draws oil from the sump 72 to lubricate the bearings 64, 100, 101 through regulating valves and rotatory joint 85 and passage 94 formed in the bore of the shaft 33. A passage 102 leads oil to lubricate the bearing 104 through the opening 103. Oil is also allowed to flow from the housing 30 into the gear housing 31. Drain plugs 107, 110 and a filler/vent plug 111 are provided.

Title: Telemetering process and station for acoustic phenomena
IPC: G01S11/14
Filed: 1966-04-01
Abstract: 1,137,922. Sound level monitoring. AEROPORT DE PARIS. 1 April, 1966 [5 April, 1965], No. 14602/66. Heading H4D. In a system for making measurements of ambient noise level and transmitting them to a remote point for recording, test signals for monitoring the operation of the system are transmitted after each measurement. For measuring noise at an airport, each of a plurality of measuring stations is connected to a central recording point by a telephone or radio link. At each station the transmission of measurement signals 60 is initiated when the output of a microphone exceeds a threshold amplitude 59, and is terminated after a predetermined period 61 or when the noise level drops below a predetermined value. Test signals 62 from a first test oscillator are then transmitted for a predetermined period 63 and permit monitoring of the overall operation of the measurement and transmission system. Test signals 64 from a second test oscillator may then be transmitted for a further predetermined period 68 for monitoring the operation of those elements of the system which follow the microphone. Alternatively, the order of the two test transmissions may be reversed, or the first tear. may be omitted. By comparing the signals 62, 64 as recorded the system-generated noise of the microphone and transmission system may be separately determined and the complete system may be calibrated. At the central recording point a multi-channel receiver is switched to supply signals transmitted from a selected measurement station to either a graphic recorder or a magnetic recorder or both. A talking clock is associated with the magnetic recorder. Details of timing and switching systems for applying measurement and test signals sequentially to the transmission system are given (Figs. 1, 3, 4, none shown). In a modification employing several microphones at each measuring station, a selector switches in whichever microphone first provides an output exceeding the threshold value.

Title: Regulating apparatus for the automatic charging of an accumulator battery in two stages
IPC: H02J7/32
Filed: 1947-06-03
Abstract: 651,837. Automatic control of current and voltage in battery charging systems. COMPAGNIE GENERALE D'ELECTRICITE. June 3, 1947, No. 14708. Convention date, June 28, 1946. [Class 38 (iv)] In a two-stage battery changing system wherein the first stage is at constant current for a pre-set time determined by the state of discharge of the battery B and the second stage is at constant voltage at the voltage reached by the battery at the end of the first stage, a transductor T1, R1 controls the excitation of the charging generator G during both stages and is provided with stabilizing means for damping out oscillations in its control circuit during the change to the second stage. As shown in Fig. 1, the current in the self-magnetizing winding E1<SP>111</SP> of the transductor is controlled by a winding E1 which, during the first stage, is excited in proportion to the charging current by a shunt sh, contact K then being closed. The current output of winding E1<SP>111</SP> controls a second transductor T2, R2 providing an amplified D.C. output controlling an amplidyne exciter A, E3 for the machine G. The first stage is terminated by a timer or ampere-hour meter causing a motor operated rheostat M, r2 to cut out resistance from the coil circuit of a contact-making galvanometer g. The contacts of the last, on closing, cause the interruption of the motor circuit and the opening of contact K, whereby the control winding E1 of the first transductor is now connected across the battery (in series with r1, r2 and the galvanometer coil) and establishes control for constant voltage changing. To prevent instability during the change over, negative feed-back is applied to the first transformer by a winding E1<SP>11</SP> connected across the exciter through a condenser C1. Damping is also provided by a resistor r3 which shunts a winding E2<SP>111</SP> on the second transductor. Pre-magnetizing windings E1<SP>1</SP>, E2<SP>1</SP>, shunted across the battery in series with a constant current device, are provided on the transductors. In a modified arrangement, the generator G is excited from an A.C. source through a rectifier bridge and saturable reactor, the saturation of which is controlled by the D.C. output of the second transductor. A non-linear resistor may shunt the rectifier, on either the D.C. or A.C. side to reduce the necessary size of the reactor.

IPC: B64C11/00
Filed: 1921-05-27
Abstract: 164,020. Didelot, J. F. O. June 2, 1920, [Convention date]. Propelling, steering, and manoeuvring by air and water jets and by paddle wheels.- Propulsion in air or water is obtained by means of a rotor R normally driven by a motor and carrying helically arranged vanes v against which fluid is directed by means of vanes A in a stator n adjustable in position, the fluid being admitted to the stator at p owing to the movement of the craft, and, if desired, also by means of a centrifugal pump. Other gases or liquids than the air or water in which the craft moves may be used, and the fluid may be cooled or mixed with denser fluids. Compressed fluid may be used, and in that case the rotor may be driven at a lower speed or its motor may be stopped, propulsion in the latter case being obtained by the reaction on the surrounding fluid of the fluid deflected by the vanes of the rotor. A casing c, Fig. 9, may be provided to cover the blades opposite the stator, and a suction effect may be obtained within this casing either by an aspirator connected at w, or by means of vanes u formed in the casing. Reversing is effected by moving the stator through 180‹ about the axis of the rotor, or by reversing valves controlling the injection and suction of fluid. The vanes V of the rotor R are formed with surfaces a, b, Figs. 3 and 5, at an angle of about 90‹, the apexes d being attached along helical lines on the rotor. The vanes are of rubber, metal, or other elastic material, the part b being more flexible than the part a and being divided into several fingers b<1> - - b<4> of varying thicknesses.

Filed: 1917-10-13
Abstract: 111,102. Chinese-American Co., (Assignees of Whaley, W. B. S.) Oct. 19, 1916, [Convention date]. Vaporizers, external.-Gas or air is carburetted, or oil is cracked, &c. in an appliance in which the gas or air is passed through a series of tubes in a chamber, the bottom of which is curved, and is heated bv the exhaust gases of the internal combustion engine to which producer gas is to bo supplied. Gas from a generator or retort passes from a pipe 48 to an air-heated chamber 15 in which the heavier products of distillation are separated and collect in a conical bottom 19 fitted with a door 20 for removal of the condensed products. The gases and lighter products of distillation pass through the flared end 22 of a pipe 21 which conducts the gases to an upper chamber 24, of a cracking or carburetting device 12. The gases pass through tubes 28 arranged in a chamber 30 attached to the chamber 24, and pass with high velocity against the concave bottom 29 of chamber 30 which is heated by the exhaust gases of an internal combustion engine 10, supplied by an exhaust pipe 33 and caused bv a curved plate 34 to heat the bottom 29 effectively. By reason of the deflection and heating of the jets which impinge on the plate 29, and of the collision of the particles with one another and with the heated ends of the tubes 28, the lighter distillates are broken up into their component gases, and the fixed gas passes to a chamber 36, and thence by a pipe 37 to a cooling-device 11 through which it passes at variable speeds, and is sucked by a blower 41 and passed to the internal combustion engine 10. The air in the cooler 11, which is heated by the passage of the gas, passes to a chamber 18 which heats the gas intake chamber 15. If desired, the chamber 30 may be supplied with oil, and this used to carburet air which is drawn through the chamber 15 by opening the pivoted bottom 20. The chamber 30 is fitted with a supply and drain pipes with cocks for controlling the admission of oil to the chamber 30 or for drawing it off.
