Abstract: 431,634. Instruments operated by fluid pressure ; gyroscopic apparatus. ASKANIA - WERKE AKT. - GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU, 87, Kaiserallee, Friedenau, Berlin. March 4, 1935, No. 6829. Convention date, March 2, 1934. [Class 97 (iii)] A current of pressure fluid is supplied to a rotatably mounted part of an instrument such as a gyroscopic instrument for aircraft by constructing a bearing of the rotatable part as an injector. As shown the gyroscopic rotor 1 spins on an axis 3 in a frame 2 pivoting in a vertical frame 4. Air for driving the rotor 1 is supplied from an inlet conduit 9, a conduit 8 in the frame 4 and a conduit 7 in the frame 2 to nozzles 6. The lower bearing of the frame 4 comprises a spindle 10 journalled in ball bearings 11. The conduit 9 opens into a chamber 12 surrounding the spindle 10 and forming therewith an annular nozzle 13. The conduit 8 communicates with an annular inlet opening 14 opposite the nozzle 13. The outer walls of the nozzle 13 and inlet opening 14 form a passage for the induced air flow. The conduit 8 leads to a tapered bore 19 in a bearing pin 18 carried by the frame 4. Opposite the nozzle end 20 of the bore 19, the rotatable frame 2 has a wide bore 21 opening into the conduit 7. Openings 22, 23 at the side of the opening 21 permit the entry of the secondary or induced air flow.

In the embodiment of Fig. 3 (not shown), each cylinder houses one piston which projects from each end of the cylinder and a restriction orifice within the piston permits fluid flow between two chambers formed in the cylinder by the piston. Alternatively, the cams may be secured to the drum shaft and the piston and cylinders secured to the drum. In a further embodiment, the cylinders are arranged axially of the drum and the cams comprise discs arranged transversely of the drum shaft.

Abstract: 1449224 Ni-Cu catalyst alloy TEXAS INSTRUMENTS Inc 17 Sept 1973 [29 Nov 1972] 43544/73 Heading C7A [Also in Division C1] A Ni/Cu catalyst containing one of V, La or Dg is used in the reduction of nitrogen oxides in automatic exhaust gases. A process to reduce the nitrogen oxide content of automotive exhaust gases consists of passing the gases over a dual-bed catalytic converter close to the manifold. The first bed comprises an expanded mesh of 80-20 Ni/Cr alloy coated with a nickel-copper alloy containing 25-75% Ni with 0À5-20% catalytic addition, the balance being Cu and impurities i.e. C, Si. The catalytic addition is selected from V, La and Dy, and is made by roll bonding the Ni-Cu alloy on to the base Ni/Cr alloy, vapour depositing the additional catalyst material, diffusion annealing and then expanding to form a mesh, wnich in operation, is said to prevent the formation of NH 3 , in the exhaust gas prior to passing over the second bed of the converter where the gases contact a platinum mesh catalyst member under oxidizing conditions. The presence of the additional catalyst metal improves the service life of the converter, and also improves its efficiency at low exhaust gas temperatures.

The assaying is suitable carried out by subjecting each of said separate volumes of effluent to a spectrophoto-metric analysis wherein the absorbance of light energy for a given wavelength is measured for a solution containing at least a portion of each volume, whereby the relative absorbance at said given wavelength of the respective volumes will be an indication of whether the effluents contain any of said proteins. The method is suitable for the determination of the enzymes creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) and more particularly for the determination of various fractions or iso-enzymes of those enzymes. An anionic exchange agent is preferably used and the buffer solution is suitably tris-buffered sodium chloride solution.

A workpiece feeding device for a woodworking machine comprises a movable box-like stand 6 which is adjustable in height and detachably or releasably connectable to a machine and has a work-table 5 with a straight line guide for guidance of the workpieces to the machine, feed rolls 8, 10 with vertical axes acting on one side of the workpiece, and additional feed rolls 9, 11 with vertical axes acting on the other side of the workpiece and driven in the opposite direction but at the same speed as the feed rolls 8, 10. The workpieces may be disposed in a stack in a magazine formed by guide walls 2, 3, 4 and one roll 10, 11 of each pair is associated with the magazine to feed the workpieces successively to the other pair of rolls 8, 9. The rolls are connected by universally jointed shafts to a transmission box and a common infinitely variable speed motor. The roll 11 adjacent the magazine is provided with flats whereby when a lowermost workpiece is removed from the magazine, a flat is parallel to the feed path to permit the next workpiece to fall into the path. The work-table consists of two parts 17a, 17b, each of which carries one pair of the rolls. The part 17b is adjustable relative to the part 17a by a spindle 20 in screwthreaded engagement with a nut 21 on the part 17b to accommodate different widths of workpieces. In another embodiment, Figs. 4 and 5 (not shown), each pair of rolls 30a, 30b and 31a, 31b are driven through friction couplings by a separate feed apparatus 30, 31, apparatus 30 being detachably fixed to the stand in a position above a part 38 of the work-table which carries, below its surface, the apparatus 30 and is adjustable relative to fixed parts 37, 39 of the table transversely of the direction of feed of the workpieces. The workpieces are stacked in a magazine comprising guides 2, 3, 4 and one roll 30b, 31b of each pair has flats 35 to allow the workpieces to fall successively between the rolls and be fed forwardly. Adjustment of the height of the stand is effected by feet at the lower end of vertical spindles received in threaded bushes.

Abstract: 1,163,230. Fluid pressure brakes. KELSEYHAYES CO. 4 Oct., 1967 [31 Oct., 1966], No. 45144/67. Heading F2F. In or for a vehicle having drum brakes and disc brakes without return springs, a pressure regulating valve for insertion in the line between the master cylinder 10 and the disc brakes 18, has a valve 32 biased by a spring 31 and arranged to prevent supply of fluid to the disc brakes 18 until the pressure in the master cylinder line 14 is sufficient to overcome the force of the return springs in the drum brakes. The biasing spring 31 is seated on a piston 35 so that downward movement of the piston 35 causes a pressure differential between drum and disc brakes, the differential becoming reduced as the master cylinder pressure is increased due to the elongation of the spring 31. As described, the drum brakes 13 are connected directly to the master cylinder 10. At master cylinder pressures less than 60 p.s.i. a diaphragm 28 is deflected downwards so that the orifice 33 is sealed against a metal washer 29, preventing supply of fluid to the disc brakes 18. Further increase of master cylinder pressure causes the diaphragm 28 and washer 29 to move downwards causing fluid to pass through a peripheral slot 34 and apertures 55, 56 to the disc brakes 18. Further increase in master cylinder pressure causes downward movement of the piston 35 against the force of springs 37, 38 so that shoulders 53 engage a seal 47, preventing fluid flow past the piston 35 so that the piston acts as a pressure amplifying device. Further increase in master cylinder pressure causes elongation of the spring 31 which reduces the drum/disc brake pressure differential. The disc brakes are preferably applied to the front wheels.
