Title: A device for automatically replenishing the oil sump of an internal combustion engine with oil from an oil supply
IPC: F01M11/06
Filed: 1965-05-07
Abstract: 1,106,866. Bearings; valves. MASCHINENPABRIK AUGSBURG-NURNBERG A.G. 7 May, 1965 [8 May, 1964], No. 19323/65. Headings F2A and F2V. An apparatus for automatically replenishing the oil sump of an internal combustion engine with fresh oil from a reservoir, comprises a float control means actuated in dependency on the oil level and a valve for opening and closing a fresh-oil supply duct, said valve operating independently of the float control means when the oil-pressure in the engine falls below a predetermined level. In an embodiment, a float control system installed in the oil-sump of an internal combustion engine has a ball 3 floating on the oil surface 2. A lever 4 is connected to the ball 3, is pivoted at 5 on the oil-sump wall, and actuates a needle-valve 6 which co-operates with a valve-seat 7 so as to communicate with a passage 8. The latter is blocked by a valve 11 which is mounted in a cylinder 10 and is retained in position by pressure of lubricant supplied through a duct 14 from the lubricating circuit and acting on an annular surface 12 of the valve. When the engine is stationary and no pressure is applied to the valve 11, the latter descends and the passage 8 connects with a fresh-oil reservoir 20, via a duct 19 and, if the needle-valve 6 is open, the sump will be replenished with fresh oil. The valve 11 may be retained electrically during the operation of the engine and, when the engine is stationary and in a tilted position, may be prevented from opening by a pendulum-catch, having one end pivotally mounted in the valve 11 and the other end 16 engageable with an abutment 17 in the cylinder 10. In a modification, the weight 16 of the pendulum catch is allowed to pass downwards through an elongated opening 22, Fig. 2, so as to allow replenishment of lubricant to be effected when the engine is tilted in the direction 23 but not when the engine is tilted in the direction 24.

Abstract: 887,578. Aerials; R.F. couplings. ATLASWERKE A.G. June 1, 1960 [June 1, 1959], No. 19396/60. Class 40(7). "Shell" waves, i.e. parasitic oscillations, on a conductor in the radiation field of an aerial are suppressed by surrounding the conduits at various points with a ferromagnetic material of high self damping at the frequencies to be suppressed. The cable 5 feeding an aerial 1, 2 is surrounded by ferromagnetic dampers 6-11. Placing these at current maxima of the quasi-stationary energy distribution suppresses "shell" waves over a narrow band of frequencies and placing one at the earthed foot of cable 5 suppresses a wider band. Support rods and bracing wires may be similarly treated

Polymers of C 2-8  mono-olefins are treated to improve their heat stability by contacting with a composition formed by mixing (i) a compound MR n , where M is a metal of Groups I A , II A  or III A  of the Periodic Table, n is the valence of the metal and R is hydrogen or a C 1-20  hydrocarbyl radical, and (ii) a salt of a metal of Group VIII of the Periodic Table of formula M<SP>1</SP>(OOCR) m  where M<SP>1</SP> is the metal of valence m and R is hydrogen or C 1-20  hydrocarbyl. Specified polymers are of ethylene, propylene, 1-butene, 1- octene and 4-methylpentene-1, optionally copolymerized, e.g. with propylene, butene-1, octene-1 or 1,3-butadiene. Many suitable hydrides and organometallic compounds of aluminium, potassium, lithium, beryllium, magnesium, barium, sodium and gallium, and organic acid salts of nickel, iron, cobalt, palladium and platinum are listed. The process is said to involve elimination of terminal vinyl unsaturation from the products which are characterized by infra-red spectra having no absorption bands at 10À1 and 11 microns. Trans-internal unsaturation may be eliminated by carrying out the process in the presence of hydrogen, whereby products having no absorptions band at 10À35 microns may be obtained.

July 14, 1932, No. 19935. Convention date, July 16, 1931. Addition to 385,831. [Class 135.] In apparatus for controlling the feed valve 58 of a boiler or the like in accordance with the relationship between the rate of steam delivery and the rate of water supply, and with the boiler water level, as described in the parent Speci. fication, the feed valve is actuated at a distance in accordance with the position of the control member through self - synchronous electric motors. A pilot valve on the control member 69, Fig. 2, controls the passage of pressure fluid through a sleeve 75 to one end or other of a piston 76 which rotates a shaft 71 carrying the rotor of the transmitting motor 72. The sleeve 75 is continuously rotated by a worm 77 and drives the pump 78 supplying the pressure fluid. The shaft 73 of the rotor of the receiving motor 74 operates a pilot valve 80, Fig. 3, controlling the supply of pressure fluid, such as oil, to a piston 85 on the spindle of the feed valve 88. The pilot valve is rotated continuously by the pump 79 supplying the pressure fluid to the piston. A rack 89 on the upper end of the valve spindle meshes with teeth on and rotates the stator of the receiving motor, thus repositioning the pilot valve after operation of the feed valve. A clutch member 92 is normally held out of engagement with valve spindle by the oil pressure in bellows 83 connected to the pump 79. When the oil pressure falls below a predetermined value, the clutch member is released and locks the valve spindle. The valve may be opened by a hand-wheel 17a having a screwed spindle 95 engaging the upper end of the valve spindle. Rotation of the hand-wheel 17a rotates an arm 97 having inclined teeth 99 which ride up on mating teeth at the top of a shaft 100 and opens a valve 102 across the ports leading to the opposite sides of the piston. At the same time, a collar on the shaft depresses the clutch lever 93 and releases the clutch member, and a mercury switch 103 is tilted to open the circuit of the motor driving the pump 79.

Cases with internal horns.-Relates to gramophones of the kind claimed in the parent Speciiication. in which the sound chamber is adapted to provide space for storing records when a movable wall of the chamber, formed of a number of parts hinged together, is moved against a. side of the casing. According to the invention, the movable wall is made in two parts so connected together that they lie end to end when the instrument is in use, and the connected ends are moved apart when the movable wall is shifted to provide space for records. A specially constructed record-storing case is also provided. Fig. 2 shows in plan the sound chamber, into which sound is deflected from a passage (not shown) by a block 28, as described in Specification 261,242. The movable wall of the sound chamber consists of two parts 12, 13, the part 12 being hinged at 11 to a fixed partition 10, and the part 13 being carried by a pair of horizontal arms 15. These are fixed respectively to the upper and lower edges of the member 13, and are pivoted at 16. An arm 18 is fixed to an end of the part 12, and is connected by a link 17 to the lower arm 15, both members 17, 18 lying in a recess 19 in the base of the casing 1. When the members. 12, 13 are moved to the position shown in dotted lines, to form a wall of the sound-amplifying chamber, their ends are brought together. With the parts 12, 13, 15, 17 in the position shown in full lines, the arms 15 lying against a curved plate 21, space is provided in the casing for the insertion of a record holder in the form of a drawer. The holder, shown in Fig. 4, comprises a casing having a front wall 23, which forms a part of the outer casing of the gramophone when the holder is inserted in the sound chamber, a rear curved wall 24, and top and bottom plates each formed in two parts 22<a>, 22<b>. The parts 22<b> are attached to a portion of the curved wall 24 which is hinged at 25, and these parts together form a lid which can be opened as shown in dotted lines. A pair of double links 26 connect the body of the casing to the lid. A number of superposed sheets of paper, celluloid, &c. are fixed in the casing, being held at one corner by bolts 39. The bolts also pass through distance pieces, interposed between the corner portions of the sheets, and the sheets, thus spaced, serve to separate records placed within the holder. The holder is automatically looked when pushed into the gramophone casing by spring-controlled hooks 29 adapted to engage with fixed vertical bars 32. Handles 40, 41, Fig. 3, are provided respectively on the front wall of the record holder and of the lid of the casing: and to relieve the hinge of the lid from strain when carrying the machine, hooks 42 are provided on the front of the lid, to engage in apertures in fixed plates 43.
