Abstract: 617,940. Expanding pulley gearing. ASQUITH, Ltd., W., and JOHNSON, A. Sept. 27, 1946, No. 28864. [Class 80 (ii)] In expanding-pulley gearing, simultaneous positive adjustment of a driver A, B and follower C, D is effected by a chain K engaging oppositely handed pairs of nuts F, G and H, J, each pair being operatively connected to the opposite flanges of one pulley. As shown, the pulleys are simularly constructed, one flange, as B, being controlled by a transverse pin B<4> therein passing through an axial slot in the input sleeve Q and engaging a sleeve B<3> rotatable in a sleeve G<2>, and the other flange, as A, being controlled by a transverse pin A<4> therein passing through axial slots in the sleeves Q, B<3> and engaging a rod A<3> rotatable in a sleeve F<2>. The sleeves F<2>, G<2> are slidably but non-rotatably mounted in the gear. casing and are threaded to engage the nuts F, G. The input and output sleeves Q are splined to the shafts O<1>, S of a driving electric motor and a driven gear-box respectively, a tachometer generator T being also driven. The chain K is driven from a sprocket L, Fig. 2, which may be actuated by a hand wheel or remote control means, a tension pulley M being provided to allow the chain K to be slacked clear of the nuts F, G and H, J for independent initial adjustment thereof. The pulley surfaces may be formed with radial, grooves U to reduce belt slip. Lubrication of the sliding surfaces is provided through grease nipples (not shown) on the pulley bosses and oil passages W, a flexible boot V preventing the lubricant reaching the pulley surfaces.

Title: Improvements in instruments or apparatus used for determining the compression and explosion pressures of internal combustion engines
IPC: G01L23/02
Filed: 1922-08-02
Abstract: 203,464. Pearson, J. L. Aug. 2, 1922. Piston and spring pressure gauges with automatic maximum measurements.-A gauge for measuring the compression or explosion pressure in the cylinder of an internal combustion engine has a maximum finger which is raised by the plunger of the indicator and then secured to its maximum position by the sideways pressure of a small spring. The cylindrical body A of the indicator is screwed into the sparking plug hole for compression pressures or in an adapter for explosion pressures, and houses a piston D having an extension I and a shoulder on which rests loosely the maximum finger H, the piston D being acted upon by a spring G inside a barrel B which screws on to the body A. The vertical face of the finger H adjacent the piece I is marked with a scale. When the compression &c. pressure acts upon the piston D the finger H is raised, but when the piston returns to normal position the finger H is retained by the sideways pressure of a small spring E so that the reading on the scale on the finger, level with the top of the extension I, gives the required pressure. In a modification the barrel K screws into the body J and is marked on the outside with a helical scale T. The barrel is screwed down until the pressure just fails to lift the maximum finger N, when the required pressure is read at the point where the scale T disappears into the body J.

Title: An improved method of forming nickel oxide capable of reduction at a low temperature
IPC: C01G53/04
Filed: 1931-10-21
Abstract: Nickel oxide, capable of reduction at a low temperature, is obtained by treating nickel oxide produced at a high temperature or superficially oxidized nickel with a suspension of an alkaline earth oxide or hydroxide, particularly lime, in a solution of a hypochlorite, hypobromite or hypoiodite.  The superficial oxidation may be effected by exposure to the atmosphere or by a treatment involving a higher temperature.  For the production of a nickel catalyst for hydrogenation of fats or oils, nickel, oxidized, for example, by dipping in nitric acid and heating until the coating of nitrate is converted into oxide, is immersed in a suspension of bleaching powder.  The nickel matrix with its adherent coating of changed and newly-formed oxide is removed and washed with water, treated with dilute hydrochloric acid to remove adherent lime, and again washed with water.  It is then reduced in a slow current of hydrogen at 300 DEG  C., the reduced metal being strongly adherent. To regenerate the catalyst, adhering fat is removed and the matrix is then subjected to treatment with a suspension of lime in a hypochlorite, hypobromite or hypoiodite, and subsequently treated as above.  If necessary, the bleaching powder suspension may be decanted or filtered, and calcium hydroxide be produced in the solution by the addition of caustic soda.ALSO:An adherent layer of nickel oxide capable of reduction at a low temperature is produced on a nickel surface by treating superficially oxidized nickel with a suspension of an alkaline earth oxide or hydroxide, particularly lime, in a solution of a hypochlorite, hypobromite or hypoiodite.
