Title: Improvements in four stroke cycle internal combustion engines for use in aircraft
IPC: F02B1/00
Filed: 1922-12-11
Abstract: 190,173. Durand, E. H. M. E. Dec. 12, 1921, [Convention date]. Regulating; valve-gear; valves. - Fourstroke engines for use on aircraft are arranged to work with a supplementary charge at high altitudes by employing the front side of the piston to compress air or mixture. I n a single - cylinder engine, a sliding plate c<1>, Fig. 1, is used to close the front end of the cylinder, the connecting- rod a<1> passing through an oscillating closure a<2>. The pump supplies to a reservoir between the valve b<2> and the cylinder valve h, the latter being controlled by an axially adjustable cam i<1>, either automatically or by hand according to barometer indications. Mixture may be drawn from the main carburettor, or air may be forced through a supplementary carburettor, or air only may be supplied as the added charge. The pump valves and the admission valves h may be replaced by an oscillating plug valve. In a V-engine, the oscillating plug valve m, Fig. 6, is placed in a conduit b' connecting the two cylinders; a pipe b<8> leads to the crank case, in which the supplementary charge is compressed; the valve controls delivery to the two cylinders alternately and also admits the charge to the crank case. In a four-cylinder engine with the front ends closed as in Fig. 1, a ported cylinder is used to control all the pump spaces; each cylinder combustion space receives a charge from two pump spaces. In a revolving-cylinder engine, the front ends being closed by sliding plates c', Fig. 14, a ring valve q controls the pump spaces, the valve being driven from an internal wheel c<3> on the crank case through the pinions r, t; with a sevencylinder engine, the valve rotates at seven-eighths of the speed of the engine. Each combustion space is supplied from two pump spaces.

Title: Improvements in and relating to conveyor systems
IPC: B65G47/48
Filed: 1927-12-14
Abstract: 287,891. Lamson Co., Inc., (Assignees of Klyver, A. N.). March 29, 1927, [Convention date]. Discharging devices for endless-belt canveyers.-In an endless belt conveyer in which each load carrier is provided with a pin which on engaging an arm suspended in its path causes a deflecting bar to move across the belt to transfer the carrier to a branch conveyer, means are provided whereby the bar will be turned into operative position when the arm is engaged by pins of a certain height, but will remain in inoperative position when the arm is engaged by pins of other heights. The deflecting bar 11 is mounted on a vertical rock shaft 21 which is connected by a crank 20, link 19, bell-crank 17, link 16 and crank arm 15 to a horizontal rock shaft 14 arranged above the conveyer and having freely suspended therefrom an arm 30 which depends into the path of pins 48 mounted on the carriers A. An arm 31 is secured to the shaft 14 to turn with it adjacent to the arm 30 and carries a pin 32 which extends in front of the arm 30. The hooked end 37 of a latch 36 normally is in engagement with the arm 31. This latch is mounted on a shaft 34 carried by a bracket 33 secured to the arm 30. An arm 35 secured to the shaft 34 carries a stud 42 which passes through an aperture in the arm 30 and carries a disc 44 with which certain of the pins 48 are adapted to engage. A spring 38 normally, maintains the arms in the position shown in Fig. 3. A number of rows of sockets 45 of different depths for the pins 48 are formed in the carriers A.. If a carrier is to be transferred to the branch conveyer 9, a pin must be inserted in a socket of such depth that the upper part of the pin only extends sufficiently to engage the lower part of the arm 30 arranged at the junction of the two conveyers and does not come into contact with the disc 44. Carriers provided with longer pins will cause the rocking of the arms 30, 35 without moving the shaft 14 since the pins will engage the disc 44 and by moving it to the right effect the disengagement of the hook 37 from the arm 31. These carriers therefore pass the junction without actuating the deflecting bar, and will move along the conveyer past similar junctions until they meet an arm 30 mounted at such a height that the pins strike its lower end. The bar 11 may be held temporarily in deflecting position by latch mechanism 27 released by the passage of a carrier over an actuating lever 28 on the branch conveyer. When the branch conveyer is full, the latch is out of action, and as the bar is not held in the deflecting position no more carriers will be diverted until the branch is cleared.

Title: Vehicle braking system
IPC: B60T8/82
Filed: 1970-07-13
Abstract: 1308502 Aritiskid braking systems KELSEYHAYES CO 13 July 1970 [5 Sept 1969] 33964/70 Heading F2F In a vehicle hydraulic braking system a varying output signal is generated in response to the occurrence of a skid condition which is fed to a control circuit generating pulses the width of which vary with the magnitude of the output signal to vary the braking pressure. The hydraulic fluid is controlled by a control device to an inlet 18 of which the fluid is fed before passing through a cylinder 60, past check valve 76, grooves 92 and bore 90 of a cylinder 82, and groove 88 of a control piston 46 to an outlet 16. Piston 46 controlling check valve 76 is operated by a vacuum suspended diaphragm 42, Fig. 5 (not shown), which is operated by the admission of air to one side (50), under the control of a solenoid 48, operated valve arrangement. When the solenoid is actuated by the control circuit a plunger 228 moves a cap 156 of the valve arrangement into a cylinder (144), Fig. 5 (not shown), to engage a sealing washer 164 thereby closing a radial path 178 communicating with vacuum by way of a line (52). At the same time a space is formed between a seal 160 and washer 146 and air passes through voids between projections 182, 186 and through path 190 to act on the diaphragm (42). Air pressure acting on a flexible sealing flange 188 causes it to be deflected into engagement with a counterbore 159 closing a second path 174 to vacuum. As the diaphragm (42) moves leftwardly the piston 46 disengages a shoulder 86 and valve 76 moves under the bias of a spring 84 so that groove 92 is effectively within the bore 82 and pressure to the brake cannot increase. By rapidly actuating and deactuating solenoid 48 the diaphragm assembly (42) is maintained at a preselected position at which the brake pressure is at a desired magnitude. The control circuit, Fig. 2 (not shown) achieving this comprises D.C. converters (300) receiving signals picked up from wheel sensors (28) on each wheel, the output of the converters being fed to a summing circuit (302) and then to a differentiator. The differentiator output passes to a threshold circuit (308) feeding a signal to a summing network (316) and also to a triangle wave generator, 312 the output of which is also fed to the summing network. The summing network passes a signal to a valve driver circuit 324 controlling solenoid 48. In the embodiment shown the rear wheel brakes only are controlled but the front, or front and rear may also be controlled.

Abstract: Nickel plating baths include as brightening agent ascorbic acid or isoascorbic acid.  Saccharin may be present in permalloy platings which include Ni and Fe, Co, Ca, and Por selected combinations thereof with Ni.  The ascorbic acid acts as anti-oxidant in Ni/Fe platings preventing the formation of FeIII.  The Ni salt may be sulphate, chloride, or sulfamate. Preferably a Ni anode is used to replenish Ni ions, and iron is added to the electrolyte as a salt. Suitable substrates are copper or its alloys, gold, silver, platinum, stainless steel or other metals, or non-conductors such as glass, ceramic or plastics which have been made conductive by coating with copper or gold.
