Title: Catalytic dehydrogenation of olefins
IPC: C07C5/32
Filed: 1957-03-15
Abstract: The dehydrogenation process of mono-olefins is started by treating fresh catalyst the active ingredient of which is calcium nickel phosphate, in the form of pellets which contain a combustible lubricant, e.g. graphite, with (i) hot air at a maximum temperature of 600 DEG  F., and then (ii) passing super-heated steam and a controlled amount of an oxygen-containing gas, e.g. air, so that the combustible material is oxidized and the catalyst is heated to the dehydrogenation temperature.  The hot air is preferably passed until the catalyst bed is between 225-450 DEG  F., and the superheated steam is preferably at 400-1400 DEG  F. and is passed with air until the catalyst bed is between 900-1150 DEG  F. In examples given approximately 18000 lb./hour of air was passed through a butene furnace to a reactor containing the catalyst in a dehydrogenation unit.  The temperature of the air to the reactors was raised to 340 DEG  F. in 1 hour and maintained at this for 7 1/2 hours and then raised to 400 DEG  F. in a period of 1 hour and 20 minutes and maintained at this temperature for 2 hours 20 minutes, so that the catalyst bed attained a temperature greater than 225 DEG  F. and preferably between 550-580 DEG  F. before the heating was continued for 12 1/2 hours by passing superheated steam with a controlled amount of air

Title: Improvements in or relating to apparatus for the measurement or investigation of torsional vibrations
IPC: G01H1/10
Filed: 1947-04-01
Abstract: 634,117. Indicating torsional vibrations. NAPIER & SONS, Ltd., D., and KNOX, L. H. B. April 1, 1947, No. 8754. [Class 40 (i)] [Also in Group XL (b)] In a device for indicating torsional vibrations of a shaft a disc A is firmly coupled to the shaft by a flange A<SP>1</SP>. A further disc B is carried on a short shaft C which " floats " on needle bearings inside the flange A. The inner end of shaft C is coupled to the inside of flange A<SP>1</SP> by leaf springs D. Light passes through holes A<SP>3</SP>, B<SP>1</SP> in the periphery of the discs to a photo cell H, the response of which is indicated on a meter J. Torsional vibrations of the shaft cause relative movement between the two flanges reducing the light to the cell as the shaft rotates. Studs F prevent fracture of the springs. In a simpler embodiment (Fig.3, not shown), a flange carried on the shaft has a sleeve surrounding the shaft and carrying a ball race on which the second disc rotates, the friction of the race being sufficient to keep the discs normally aligned. The Provisional Specification also describes a torque-measuring system in which misalignment of a pair of spaced discs having holes in their peripheries reduces the light reaching a photo-cell.

Title: Improvements in or relating to fret-sawing devices, particularly fret-saw frames and blades
IPC: B65H45/101
Filed: 1934-03-20
Abstract: 438,881. Fret-saws. HAUNSTETTER, A., 17a, Wellenburgerstrasse, Goggingen, Augsburg, Germany. March 20, 1934, No. 8771. Convention date, Feb. 13. [Class 61 (ii)] The ends of a fret-saw frame are bent to form surfaces 3, 4 at an angle to one another and the surfaces are provided with slits 5 for the reception of the heads 7 of a blade 6, the slits in one surface being at an angle to the slits on the opposite surface. Normally the distance between the end surfaces 3, 4 is greater than the length of the blade and the tension exerted when the blade is inserted holds the blade head against one side of the slit to prevent lateral play. Grooves near the ends of the surfaces 3, 4 retain the blade heads in position. Several slits of varying widths may be formed in the end surfaces to accommodate blades of different thicknesses, the narrowest one being at the closer ends of the surfaces and the widest at the distant ends to ensure greater tension being put on thicker blades.

Patent GB-582182-A (GB)
Title: Improvements in or relating to power driven fluid pumps
IPC: F04C11/00
Filed: 1943-06-03
Abstract: 582,182. Two-stage pumps. WORLIDGE, R. F., and INTEGRAL, Ltd. June 3, 1943, No. 8943. [Class 102 (i)] In a pump in which one or more pistons 21 of a second-stage unit are moved in radial cylinders 20 on their working strokes by a cam or eccentric 22 with which they are held in contact by pressure-fluid supplied by a first-stage gear unit 11, 12, the two units being driven by a common shaft 5, the output of the pump is automatically and progressively regulated by controlling the first-stage pressure in accordance with variations in the output pressure, zero output being obtained when the first-stage pressure is reduced below a predetermined minimum. One side of the gears 11, 12 is supplied with oil by an inlet 14, the other side communicating through a port with an annulus 18 on the opposite side of a partition 8 separating the two units. Ports leading to the annulus 18 and to a delivery annulus 28 are controlled by spring-pressed double inlet and outlet non-return valves 24, 25 for the cylinders 20. Passages 31 connect the delivery annulus 28 with the end of the stem of an interstage poppet valve 17, which is controlled by weak and strong springs 33, 34. The annulus 18 also communicates through a port 35 with a chamber below the valve 17, a chamber above this valve communicating by passages 37, 36 with the inlet 14 or with a drain connection. An increase of the delivery power pressure acting on the valve therefore reduces the required pressure from the first-stage acting on the annular surface of the valve surrounding the stem. This reduces the working strokes of the pistons, and the delivery is correspondingly reduced. When the delivery pressure rises sufficiently to hold the valve 17 wide open without assistance from the interchange pressure, the output is reduced to zero. Maximum opening of the valve 17 is controlled by escape ports 46 connected to suction. The first stage unit may have-twice the capacity of the secondstage unit.

IPC: F02M19/12
Filed: 1918-05-30
Abstract: 130,713. Thorne, C. E. May 30, 1918. Spray carburettors.-In spray carburettors wherein the size of the jet orifice is determined by the varying positions of a needle valve provided with a screwed spindle, the needle valve is adjusted by cams on the ignition and throttle control rods of a car, the cams being so formed as to be readily applied to existing rods. In the form shown in Figs. 1, 3, and 4, a block 10, made in halves secured by screws 11, embraces the steering-post 1 and the ignition and throttle control rods 2, 3 respectively. The rods carry cams 7, 8 and washers 12, all of which are slotted to permit of their being easily slid over the shaft, and are secured by screws such as 13. The block 10 carries bearings for a spindle 14 to which are secured arms 16, 17 which in turn carry a spindle 19 to which an arm 18 is secured. The arm 16 has a contact piece 20. The spindles 14, 19 are moved against the resistance of springs 15, 21 by the cams 8, 7, which actuate the arms 16, 18. The link 22 on the spindle 19 actuates the screwed needle valve 4, Fig. 1, through a flexible link 23 and an arm 24 adjustably secured to a disk 25 carried by the valve. At starting, the rod 2 is moved to retard sparking, and the valve 4 is actuated by cam 7 and arm 8. After having started, the rod 2 is rotated to advance the ignition, in which case the lever 18 is brought back by the spring 21. During running, the actuation of the fuel valve is effected chiefly through the throttle-control lever 3. In the modification shown in Fig. 17, cams 28, 29 are secured to the ignition and throttle control rods 2, 3 and are slotted as described above. A block 31 on the steering-post 1 has a boss 31' and carries bearings for a rocking member 34 which has a projecting arm 34<11> and a downwardly pointed nose engaging with the cam 28. A lever 36, mounted on a stud 35 carried by the arm 34<11>, has a lateral portion 38 which engages with the cam 29. The boss 37 of the lever 36 bears against the arm 34<11> and has a projection 37<1> which is pressed against the rear of said arm by means of a tension spring. The lever 36 is connected to the fuel valve. The action is similar to that described above.

Abstract: 1,214,659. Arcing preventing in switches. MITSUBISHI DENKI K.K. 26 Feb., 1968 [27 Feb., 1967], No. 9193/68. Heading H1N. A current limiting device comprises a quantity of conductive current limiting material enclosed in a casing which acts as or incorporates a resistance element connected in parallel with the current limiting material. The current limiting material is such that when it is heated by a current passing through it some of the material evaporates in which state it has a high resistivity. The resistance connected in parallel with the material tends to suppress voltage transients generated when current limiting occurs. The current limiting material may be sodium, potassium or mercury. The casing must be strong enough to withstand the high pressures produced when the current limiting material vaporizes or may include pressure absorbing means. Suitable materials for the casing are listed and may be electrically resistive or may have a coating of a resistive material. The casing may also be of a material whose surface resistance decreases at high temperatures, and such a material may be surrounded with insulating material which provides the required mechanical strength.
