Title: Improvements relating to the tuning of radio receivers
IPC: H03J5/12
Filed: 1938-10-11
Abstract: 522,248. Push-button tuning mechanism. COLE. Ltd., E. K., and SHACKELL. A. Oct. 11, 1938. No, 29389. [Class 37] In push button tuning arrangements of the cam and lever type the depression of a push button lever increases the potential energy of a spring which is released at the end of the lever stroke to effect the tuning operation. The motion of the tuning gear is controlled by a governor and the adjusting means for the initial setting of the press buttons is only accessible when the latter are in the depressed position. Each press button 1 is mounted on a lever 2 pivoted on a pin 3 and provided with bifurcated arms 2a, 2b. The arm 2a projects through a slot in a sliding rod 4 which supports a pivoted cam 17 and a bell-crank lever 8 having arms 8a, 8b and pivoting on a pin 7 carrying a disc 6. The arm 8a is attached to the lever 2 by a spring 21 and cord passing over a roller 5. The rod 4 is held in the neutral position by a catch 12 engaging in a slot 11 in which position the arm 8b engages a stop 9. The tuning elements (e.g. ganged condensers) are connected through suitable gearing (not shown) to a slotted rocker bar 18. On depressing the lever 2 against the action of a restoring spring 15, the tension of the spring 21 is increased until a lip. on the arm 2b passes over the end of a spring actuated latch bar 14 thereby locking the lever (and at the same time releasing any other lever in the operative position). At the same time a projection 13 on the arm 2b contacts with the disc 6 thus raising the sliding bar 4 to free it from the catch 12 whereupon the bar moves under the action of the spring 21 until the cam 17 contacts with the rocker 18 and moves this and the attached tuning elements to the desired position. Movement of the bar 4 is controlled bv frictional contacts of the cam 8b with a roller 10 provided with any type of governor mechanism. Initial setting of the tuning is obtained by tuning in the required station manually and then depressing the lever until the freely pivoted cam 17 enters into correct angular engagement with the rocker 18 whereupon the cam is locked in the set position by a locking member 19, adjusted by a knob 20 which is only accessible when the button 1 is depressed.

Patent GB-231218-A (GB)
Title: Improvements in the manufacture and production of hydrogen or of hydrogen-nitrogen mixtures
IPC: C01B3/38
Filed: 1923-11-26
Abstract: Hydrogen-nitrogen mixtures suitable for the synthesis of ammonia are prepared by igniting hydrocarbons in the gaseous phase with air, then oxidizing the carbon monoxide in the product to carbon dioxide by treatment with steam in the presence of a catalyst such as iron oxide, and finally removing the carbon dioxide.  The oxygen present at the ignition stage should be sufficient to combine with all the carbon of the hydrocarbon to form carbon monoxide, but insufficient for complete combustion. It is desirable to preheat either or both of the reacting gases for the ignition stage and to employ fireproof material, such as magnesia, which preferably contains iron or nickel or oxides thereof, during or immediately after the partial combustion. Other gases such as hydrogen or carbon monoxide may be present. An example is given of the combustion of the methane contained in coke oven gas.

Title: Lubrication system
IPC: B60R17/02
Filed: 1928-10-18
Abstract: 315,161. Stanley Automotive Products, Inc., (Assignees of O'Brien, J. J.). Aug. 29, 1928, [Convention date]. Force-feed lubricating.- In an oiling system for motor vehicles in which the lubricant is placed in a sealed tank near a source of heat, such as the exhaust manifold, and is caused to flow by pressure acted on its surface, the discharge pipe is fitted with a needle valve which is automatically opened and closed by the starting and stopping of the motor. As shown in Fig. 1, the valve is operated by the suction of the intake manifold. A sealed tank 10 has a pipe 12 reaching almost to the bottom and at a point near the tank the pipe has a needle valve 14 connected to the free end 16 of bellows 17, of which the top end 18 is rigidly mounted. The interior of the bellows is connected by a pipe 19 to the intake manifold 20 and when the motor is operative the suction lifts the valve from its seating thereby allowing lubricant to flow. When the motor is stopped, the valve closes, and lubricant is unable to flow back from the discharge points to the tank. A minor pipe line 21 short in length may be connected to the main line 12, to admit air in order to break the partial vacuum produced in the tank 10 when its contents cool. Alternatively the valve may be operated automatically by the pressure of the oil or water supply systems of the car, by a thermostatic element placed near the exhaust manifold, or mechanically by connection to the throttle.

Title: Automatic positive anti-aeration system for engine cooling system
IPC: F28F9/02
Filed: 1975-07-18
Abstract: 1521543 Anti-aeration system for an engine radiator; cooling l.C. engines W C AVREA 18 July 1975 30176/75 Headings F4S and F4U A cooling radiator 20, Fig. 1, for a liquidcooled internal combustion engine 10 has inlet and outlet header tanks 14, 18 with finned cooling tubes 21, Fig. 2, therebetween. The inlet header tank 14 has an adjacent accumulator compartment 23 separated therefrom by a wall 24. Between the header and the accumulator, there are valve controlled passageways at upper and lower portions of the accumulator, Figs. 2 and 5. The accumulator has at its top a vent 25 and a filling opening 27 closed by a plug 28. The accumulator receives through its upper passageway heat-expanded coolant from the radiator when the radiator is hot and returns coolant to the radiator through the lower passageway when the radiator is cold. The arrangement is such that, during initial filling of the coolant system through the opening 27, the system is practically completely filled with coolant, any air entrapped in the system is removed during the first engine heating cycle, and there is no subsequent aeration of the system. The upper passage between the header 14 and accumulator 23 includes openings 33, 31, Fig. 2. The upper valve comprises a plug member 34 which is spring-loaded so as normally to close the opening 33 and which opens at a first predetermined pressure in the header tank above ambient. The lower passage comprises openings 66, 52, Fig. 5. The lower valve comprises spring-loaded closure member 60 which normally closes the opening 66 and which opens if the pressure in the radiator falls below a second predetermined pressure which is lower than the first predetermined pressure. In use, when the radiator is hot, trapped air can escape from the radiator through the upper valve to the accumulator and be vented at 25. To initially fill the cooling system, the upper valve is opened (by unscrewing a plug 38, Fig. 2) and coolant passed through filling opening 27. The lower valve opens as a result of differential pressure thereon. The coolant passes through the lower valve and the radiator fills from the bottom upwardly. An alternative lower valve, Fig. 6 (not shown) is normally open under the action of gravity but closes when pressure across the valve rises, e.g. when the coolant liquid in the radiator boils. In an alternative upper valve, Fig. 10 (not shown) the pressure on the valve spring 35 is adjustable by a screw (93). In further alternatives, Figs. 7 and 12 (not shown), the accumulator 23 is a vessel which is separate from the radiator. In each embodiment the accumulator communicates with the radiator by upper and lower valvecontrolled passages and has a vent and filling opening. The vent is provided in a filling cap (28a) in the Fig. 12 embodiment. The radiator core can be of aluminium.

Filed: 1958-09-23
Abstract: 905,063. Vehicle power steering. BISHOP, A. E. Sept. 23, 1958, No. 30402/58. Class 79(5). A power-steering mechanism has a valve 36 controlling the application of power for rotation of an output shaft 12 actuated by a rod 41 moving axially within a hollow input shaft 11 which connects the output shaft 12 with a steering shaft 13, the rod 41 moving due to lost motion between the output and the steering shafts. Two rollers 19 and 20 on an axis-pin 21 adjustably mounted between cheeks 23 and 24 on the inner end of the shaft 12 engage in a cam-groove 18 cut in an hour-glass worm 15 on shaft 11 to rotate output shaft 12 about an axis 30 along which the shaft 12 is adjustable longitudinally by a screw 31. The groove 18 varies in pitch so as to give low ratios at its centre for "straight ahead" steering and high ones when the rollers move out towards its ends for cornering. In the latter position only one of the rollers will be engaged in the groove. An alternative construction (Fig. 5, not shown) has a separate groove for each roller. The shaft 12 can also be rotated by a crank 70 which connects it to a piston 60 slideable in a cylinder 61 one end of which opens directly into the central part of the casing 10, which forms a sump for oil. A plate 47 (Fig. 3) is secured to the rod 41 by a nut 51 and a spacer 49 which, between rubber bushes 73 and 74, extends with play through a hole in a plate 72 fixed on the shaft 13. Pins 79 extend from plate 72 freely through the plate 47 and, with lost motion, through enlarged holes 80 in a casing 44 which is fixed on the shaft 13. A link 75 connects diagonally a rubber bushed pin 76 on the casing 44 with a similar pin on the plate 47, so that, when lost motion due to turning occurs at the holes 80, the rod 41 moves axially relative to the shaft 11. A spring 42 adjustably mounted between the plate 47 and the casing 44 controls the motion. At its other end, the rod 41 moves, with slight rotation, a valve spool 37. The spool 37 bears, by way of a ported washer 40 and an equalising ball 39 on a spring 38 which is considerably stronger than the spring 42 and which coacts with it to provide a degree of "feel back". Movement of the spool 37 admits from inlet 62 or exhausts through outlet 36, pressure oil to or from the sump 10 or the space 68 to move the piston 60 and thereby turn the shaft 12 by the crank 70. In place of the coupling 44-47 an elastic joint may be provided as in Fig. 6 wherein a helical sheath 13c is formed on the end of the steering shaft 13a into which a mating extension, shown in dotted lines, of the input shaft 11 fits with clearance sufficient to allow rubber to be bonded between. The rod 41a is resiliently bonded to the shaft 13a at 8 and urged axially away by a spring 42a which serves the same purpose as the spring 42 in Fig. 3. If the rubber bonding 8 is chosen to have suitable properties the spring 42a may be omitted. Specifications 818,483, 905,064 and 905,067 are referred to.
