IPC: C14B1/44
Filed: 1929-09-14
Abstract: 339,686. Turner Tanning Machinery Co., Ltd., and Schettler, G. A. Sept. 14, 1929. Carpets &c., brushing &c. mechanically. - A machine for brushing and polishing leather and the like of the kind wherein the material to be operated upon is carried into contact with and supported under the action of successive brushes 5 by means of a driven flexible conveyer 8 has (a) means for effecting relative adjustment between the individual brushes and the conveyer 8, such as by adjusting individually the supporting rollers 9 under the brushes, or (b) means for removing the rollers on which the conveyer is carried and supported so that a conveyer in endless form may be employed. In addition to providing adjustment of the rollers 9 by moving the bell-crank levers 10 which support them about their pivots by screws 12 seated against blocks 13 and bearing against the bell-crank levers 10, the rollers may also be adjusted simultaneously by moving the bars 14 which carry the blocks 13, by means of a handle 18 and cam 16 bearing against the ends of the bars. The rollers 7 which carry the conveyer 8 are adjustably mounted in removable bearings 6 and the rollers 9 may be removed through apertures in the sides of the machine frame to permit insertion and removal of an endless form of conveyer 8. The rollers 9 may be spring-mounted if desired. The drive is transmitted by a main driving belt to a pulley on the shaft 4 of the foremost brush and thence by means of a single belt 29 and pulleys 26 - - 28 on the brush axles to the brushes. The conveyer is driven by gears 49, 38, the latter being driven by a belt 35 from an adjustable guide pulley 31 over which the belt 29 passes. The brushes or brush sections may have metal bodies to prevent warping.

Title: A method of coating surfaces
IPC: B05D1/08
Filed: 1945-10-24
Abstract: Surfaces are coated with wax by spraying the wax upon the surface by means of a pistol in which compressed air or gas is used to effect the atomization and spraying of the wax so that a stream of wax passes through or adjacent to a flame of sufficiently high temperature to melt the wax and to render it plastic.  The spraying may be effected by forcing a powdered wax by compressed air or gas or by vacuum through or into a stream adjacent to an oxyacetylene or like flame which is placed adjacent to or which plays on the surface being treated.  Articles such as plates, tanks, conduits, pipe lines, machinery, roofing tiles, sheets and surfaces of wood, metal, fabric, concrete and plaster may be treated.  Fillers such as sulphur, calcium carbonate, silica, zinc dust, cement and cement fondu may be added to the wax.  Specified waxes are paraffin, ceresin, carnauba, candelilla, beeswax, petroleum jelly, lanoline, spermaceti, ozokerit, montan, shellac, chlorinated naphthalene, acra, and abril waxes.

Filed: 1973-06-14
Abstract: 1440346 Electronic fuel injection control systems INTERNATIONAL HARVESTER CO 14 June 1973 [21 June 1972] 28300/73 Heading G3N  In an I.C. engine electronic fuel injection system in which a plurality of injection valves are actuated in sequence in synchronism with intake strokes of the engine, the duration of actuation of each valve is controlled by a timer circuit triggered in predetermined phase relationship to intake strokes of the engine and controlled by two control voltage, dependent respectively on engine speed and intake manifold pressure, so as to develop, upon each triggering, an output signal after a time interval, during which a valve is actuated, having a duration which is a linear function of each of the control voltages and thus a linear function of their product. In accordance with the invention, the timer circuit, for example as shown in Fig. 5, includes a capacitor 200, a source of regulated voltage 204, a transistor 202 responsive to each triggering signal for coupling the capacitor 200 to the voltage source 204 to fix the voltage across the capacitor at a value substantially equal to the regulated voltage, a controllable current sink 210 connected in parallel with capacitor 200 and operative to discharge the capacitor at a linear rate controlled by the magnitude of one of the control voltages, and a trigger circuit 218 which is triggered from one state to another to develop said output signal when the voltage across the capacitor reaches a level controlled by the magnitude of the other control voltage. The fuel injection system described with reference to Figs. 1 and 2 (not shown) is substantially as described in application number 28298/73 and includes a timer circuit in accordance with the present invention. As shown in Fig. 3, eight injection valves 121- 128 are provided, the valves being actuated in a sequence determined by a circuit 149 and for a duration determined by four timer circuits 151- 154 connected to NAND gates 141-148 as shown. Each timer has two inputs, one receiving a control voltage on line 159 dependent upon engine speed derived from a tachometer 162 and a conditioning circuit 161, and the other receiving a control voltage on line 160 dependent upon intake manifold pressure derived from a circuit 164 and a conditioning circuit 163. Each timer may be constructed as shown in Fig. 5. As further shown in Fig. 3, a switch 165 is connected to be closed when the throttle is wide open to provide fuel enrichment, and a switch 168 is connected to be closed when the throttle is closed to operate a fuel inhibit circuit 167.

Title: Multiple motor drive for aircraft
IPC: B64D35/08
Filed: 1939-10-24
Abstract: 536,057. Driving airscrews and accessories. DEHN, F. B. (Vega Airplane Co.). Oct. 24, 1939, No. 28593. [Classes 4 and 114] [Also in Groups XXVII and XXIX] The propeller shaft of an aircraft is driven by a number of motor units through one way clutches, and the speed of the shaft is maintained constant irrespective of the failure of any motor or other variation of output by a governor acting upon the pitch change mechanism of a variable pitch propeller. Each engine has an independent lubricating system. A vacuum pump, and an oil pump respectively for maintaining a partial vacuum in certain of the instruments and for actuating a retractable landing gear are driven from the propeller shaft so as to avoid changes of output. As described two engines with inverted cylinders drive through one way clutches two pinions gearing with a spur wheel 9 upon the propeller shaft 3. A wheel 18 on the propeller shaft drives a governor spindle 17 which moves vertically under the action of a governor 15 to control a valve 20 which admits pressure fluid from a conduit 24 to a port 21 or allows it to exhaust from the port 21 to a passage 20a. The port 21 communicates with a series of holes 31 in the propeller shaft to admit the pressure fluid to a bore 32 so as to act on a plate 33 connected to a movable sleeve 34 by which the propeller blades are adjusted. For this purpose pins 43, Fig. 3, work in slots 44 in arms connected to the blade roots. When the pressure is released, springs 38 acting upon a thimble 37 and pin 36 move the sleeve 34 in the opposite direction. The pressure fluid is supplied by a gear pump 27 driven from the gear 18, pressure relief valves being provided at 65 and 67. A gear 57 at the tail of the propeller shaft drives a vacuum pump 49 and an oil pump. The mean speed of the propeller shaft is controlled by the pilot through a cable 47 passed around a pulley 46 on the governor. The propeller shaft may be level with the engine crank shafts or it may be set at a higher level to enable a gun to fire through it. A tachometer is driven from an extension 70 of the propeller shaft.

The refractive index is measured with light of wavelength 589 mÁ at a temperature of 20‹ C. Desirably, film may be stretched in the machine direction at 130- 150‹ C. at a draw ratio of 4 to 5, and in the transverse direction at 120-140‹ C. at a draw ratio 60-70% of that used in the machine direction. After step (2) the film may be heat treated at a temperature within the range of 170‹ to 250‹ C., and preferably within the range 180-230‹ C., by exposing the biaxially oriented film to an atmosphere within the specified temperature ranges for about 2 seconds to 5 minutes, while it is held at constant length or allowed to shrink by not more than 5%. In a series of 6 examples, an undrawn film 200 microns thick and 40 cm wide consisting of polyethylene 2,6-naphthalate having an intrinsic viscosity of 0À70 is stretched at a draw ratio of 3À5, 4À0 or 4À5 in the machine direction at 130‹ C. and thereafter in the transverse direction at temperatures of 120‹, 130‹, 125‹, 135‹, or 140‹ C., the refractive index of the films in the examples after stretching in the machine direction ranging from 1À550 to 1À525.
