Title: An improved protective device for preventing damage to internal-combustion engines arising from back-firing in the induction system
IPC: F02M1/00
Filed: 1931-12-29
Abstract: 387,096. Preventing backfiring through induction pipes. FEUILL•E, H., 45, Rue Benoit Malon, Gentilly, Seine, France. Dec. 29, 1931, No. 35893. [Class 7 (ii).] In the event of a backfire persisting a throttle valve 2 in the induction pipe is closed by thermal action. In Fig. 1, the valve is mounted on a pivot 9 and closed by a spring 10 when notch es 15a in a fixed spindle 14 are freed by expansion, due to the heat of repeated backfiring, of a bimetallic strip 11 ; the valve is reopened by hand through a screwdriver slot 9a in the pivot 9. A similar construction is shown in Fig. 3, but the thermostatic element comprises metallic members 16, 16a surrounded by deformable metallic casings 17, 17a, each having a lower expansion coefficient; a ratchet 19 on the valve is thus released from a fixed shaft 20.

Abstract: 522,900. Motor vehicles. DAIMLER-BENZ AKT.-GES. Dec. 20, 1938, No. 37024. Convention date, July 30. [Classes 79 (ii) and 79 (iii)] The engine 1 is situated above an axle gearing 3 and the engine and axle gearing are mounted on the frame 5 independently of each other. In the construction shown the engine is mounted at four points by elastic means 4 at the front end and 6 at the rear end, so that the engine can swing about a desired axis, e.g., a longitudinal axis passing through or near its C.G. The axle gear 3 is independently mounted at three points 8 on transverse frame members 9, 10 by means of rubber blocks as described in Specification 376,157. Although also elastically mounted the axle gear cannot swing freely like the engine. The front wheels may be mounted on swinging half-axles or on suspension links as shown in Fig. 3, and are driven from the engine through change-speed gear 11, a transfer gear 12, and jointed shafts 13, 17. The rear wheels may be driven through a shaft 14, and a differential gear may be provided between the shafts 13, 14. The engine may be over the front or the rear axle, and in order to minimise height is formed with a recess 15 between bearings to receive the upper part 16 of the axle gear.

Title: Process for the covering of continuous metallic products such as wire, tubes or strips by means of plastics materials
IPC: B05D3/10
Filed: 1962-10-01
Abstract: A continuous process for coating elongated metal (e.g. iron or steel) products such as wires, bars, tubes, profiled sections, foils, sheets or strips, with thermoplastic or thermosetting materials comprises cleaning the product, e.g. by ultrasonic vibrations or electrolytic means, heating the product in which heating treatment the surface of the product is oxidized and then reduced to give a rough surface, cooling the product and then bringing the product into contact with the coating material.  The temperature of the product after cooling may be higher than the temperature of the melting point of the coating material.  The coating material may be in the powder or molten state and may be applied by spreading, dipping, rolling or fluidized bed technique.  The product may receive a preliminary coating of zinc or aluminium by dipping in a galvanizing bath, after the cooling stage, which coating may be subjected to vibration and/or oxidation treatment to roughen the surface prior to receiving the plastic coating.  The coating of plastic material may be controlled in thickness and the coated product cooled.

Title: Fluid pressure regulator valves
IPC: G05D16/10
Filed: 1970-07-31
Abstract: 1320573 Valves; hydrostatic transmission control LINDE AG 31 July 1970 [1 Aug 1969] 37109/70 Headings F2D and F2V A valve for setting various constant pressures in a pressure line, e.g., the pressure line to the control member of the hydrostatic transmission of a vehicle, comprises a valve member biased by spring means, and a movable member for regulating the biasing effect of the spring means, the spring means being such that movement of the adjusting member in the vicinity of its initial position effects a smaller variation in pressure than movement by the same amount at a greater distance from the initial position so that a more sensitive control of pressure is obtained during the initial stages of movement. In the embodiment, the valve consists of inlet passages 23 and 24; an outlet passage 30 leading to a pressure line; an excess pressure exhaust passage 25; a valve member 9 formed with a circumferential groove 12, and bores 11 and 13; biasing springs 15 and 16 for the valve member; a bias adjusting member 3, 6; and a lever 28 movable from side to side to actuate a thrustpin 4 and the thrust pin 29 of an identical valve, and movable backwards and forwards to actuate identical valves (not shown) or valves in which the biasing of the spring means increases linearly with compression. The spring 16 falls short of the bias adjusting member 3, 6 but is guided by a spigot 8. A further spring 14 is compressed between the movable adjusting member and the valve housing. In use, the lever 28 is tilted so as to compress the spring 15 and thereby moves the valve member to a position where fluid from the inlet passages flows to the outlet passage via the peripheral groove 12 and passages 11 and 13. However, the resulting back pressure acting on the valve member moves it upwards against the force of the spring 15 until the forces due to the pressure and the spring are in balance. Further movement of the lever repeats the process. If the lever 28 is tilted to such an extent that the end of spring 16 comes into contact with the part 6 of the adjusting member, the spring 16 exerts an additional force on the valve element and brings about a greater rise in pressure in the outlet passage than previously for an identical movement of the lever. The non-linear biasing characteristics may also be obtained by using a single helical wire spring, the turns of which are of varying pitch or strength or a plurality of springs of different stiffnesses arranged in series so that a stiffer spring comes into action when the next less stiff spring is completely compressed or is compressed up to an abutment. Should the pressure in the passage 30 rise so steeply that the force exerted by it exceeds that of the biasing spring, the valve member is moved upwards and fluid escapes through passage 25 to relieve the excess pressure. The compression of the biasing spring is controlled manually or by a centrifugal governor.

The relative proportions of (a) and (b) are so chosen that the viscosity of the blend is between 2 and 10 cs. at 210 DEG  F.  A typical blend is 92 weight per cent of trimethylolpropane tricaprylate with 8 weight per cent of "Ucon" LB 1145 ("Ucon" is a Trade Mark).  Lubricating oil compositions may be formed by adding to the base oil one or more antioxidants and/or copper passivators. Suitable antioxidants are dioctylphenothiazine, and dioctyldiphenylamine either alone or in combination with each other or with another amine-type antioxidant, e.g. phenyl-a -naphthylamine. Suitable copper passivators are imidazoles, pyrazoles, triazoles and a compound available commercially as DPL 297 which is of unknown constitution but contains aromatic, acid and amide groups as identified by spectographic examination.

In a system in which negative modulation is employed, I.F. amplifier 2 feeds a video detector 12, the output of which across toppeaking circuit 19, 20 is fed to a video amplifier 14. The output of the amplifier 14 is fed to the cathode of the picture tube 5 and its gain is controlled by means of a variable cathode resistor 18. The output of the detector 12 is also fed, in opposite phase, via H.F. choke 22 to a second load resistor 23 to which is connected the grid of an A.G.C. "gate" valve 25.
