Title: Coupling device for aligned shafts
IPC: F16D3/48
Filed: 1928-01-13
Abstract: 283,589. Anger, J. R. Jan. 15, 1927, [Convention date]. Universal joints. - A readily-disengageable coupling for shafts subject to disalignment comprises plates 2 secured, as by cotters 3, to the shaft ends 1, and connected by three pins 5 engaging with play in blind holes 4 formed in the plates. The pins may be of hard wood, cork, fibre, or rubber, and preferably have play in each plate equal to half the total misalignment or are enlarged at one end to engage frictionally in one plate and have play in the other equal to the misalignment, so that in either case they are free to rotate. Alternatively, the pins 5 may be rigid or integral with one plate. According to the Specification as open to inspection under Sect. 91 (3) (a) a greater odd number of pins than three may be employed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in fluid operated means for controlling apparatus at a distance
IPC: F15B9/08
Filed: 1941-02-01
Abstract: 544,793. Fluid-pressure servomotor-control systems. DODSON, E. Feb. 1, 1941, No. 1335. [Class 135] A remote control system of the kind in which a sender unit forwards a variable fluid-pressure through a pipe line to a receiver unit comprising a power device and control valve actuated by a pressure sensitive device is fitted with a biasing device which is responsive to and normally overridden by the pressure in the pipe line but is operative in the event of failure of the pressure in the pipe line to co-operate with the pressure sensitive device to move the power device to a pre-determined position. Fig. 5 shows a receiver unit for use with the sender unit described in Specification 483,049 for operating the throttle valve of an internal combustion engine used on aircraft and adapted to put the throttle in the position corresponding to cruising speed in the event of the pipe line being fractured. When used to control an aircraft rudder, the rudder is returned to a central position on fracture of the control pipe line. The power piston 11 is coupled by linkage to the throttle valve and is actuated by oil under pressure controlled by a piston valve 12 actuated by fluid pressure admitted through 19 from the control line acting on a spring-loaded diaphragm. A second diaphragm 36 maintains the valve in alignment with its seat and acted on by follow-up springs 37. These springs are variably compressed by movements of the power piston acting through a link 16 and a lever 13 pivoted at 14 to a bracket 15. A third diaphragm subject to control line pressure is adjustably loaded by springs 71 so that in the event of the pressure falling an abutment 74 engages the diaphragm to move the valve into the position required to enable the power piston to move the throttle into the position corresponding to the cruising speed of the aircraft. In the event of the oil pressure failing springs 23 coupled by a link 25 with the lever 13 moves the power piston to the position reouired to open the throttle to a position suitable for starting. Specification 534,986 also is referred to.

Abstract: 100,052. Frommer, R. von. Jan. 30, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Breech actions, sliding breech-block.-Consists in a straight-pull bolt action wherein the firing- spring is stressed by the closing movement of the breech-bolt, which is maintained in the closed position, against the action of the firing-spring, by a detent. In the construction shown in Figs. 1 and 2, the firing-spring 6 bears at the front against a shoulder on the firing-pin 3, and at the rear against a partition 7 in the breech-bolt. When the bolt is pushed forwards the firing-pin is retained by the sear 5, Fig. 1, and the spring is compressed. The breech-bolt is maintained in its forward position by a hooked catch 10, 11, Fig. 2, pivoted to the handle, and adapted to be automatically released when the handle is grasped. In the modification shown in Fig. 3, the detent consists of a spring pin 13 entering a bevelled recess in the breech-body. In another modification, the ejector 15, Fig. 4, serves as the detent by bearing against a bevelled lug 17 on the bolt.

Filed: 1929-01-15
Abstract: 327,996. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Jan. 15, 1929. Organo-stibinic acids are prepared by diazotizing an o-, m-, or pcarbamino-arylamine and treating with an antimony compound in known manner. The products, in the form of their salts with organic or inorganic bases, possess therapeutic properties. According to the example, p-carbaminophenylstibinic acid is obtained by treating diazotized 4-carbamino-1-aminobanzene with a solution of antimony oxide in hydrochloric acid, preferably in the presence of glycerine (see Specitication 244,746); its salts with potash or other alkalies and nitrogen bases are described. In the same way, 2-chloro-4-carbaminophenyl-1- stibinic acid is prepared from 2-chloro-4-carbamino-1-aminobenzene and converted into its potassium salt. 2-Chloro-4-carbamino-1-aminobenzene is prepared by treatment of 2-chloro-4-aminoacetanilide with a cyanate and splitting off the acetyl group from the resulting carbamino compound.

Title: Method of producing high purity aluminium chloride
IPC: B01J2/16
Filed: 1978-01-16
Abstract: In a process for the production of aluminium chloride by condensation of gaseous aluminium chloride in a fluidised bed of aluminium chloride particles, the gaseous aluminium chloride is introduced into the bed at an inlet speed of 18 m/s to 90 m/s. The size of the particles of aluminium chloride in the bed is also maintained at less than 500 microns by periodically removing the larger particles which stay in the lower part of the fluidised bed.

Abstract: 124,495. Mandleberg, J. H., and Mandleberg &. Co., J. Feb. 5, 1916. Varnishes.-Balloon and like fabrics or materials are rendered impermeable to gases by impregnation and coating with a solution of a composition consisting of 100 parts of rubber, 1-5 parts of ceresine or paraffin wax, ¥-2 parts of litharge, and 2-4 parts of sulphur. The composition is made by working the rubber, prior to addition of the other ingredients, with water-cooled dry mixing rollers so that its nerve is wholly or practically destroyed, the remaining ingredients are now separately mixed in and the mixture thoroughly worked. A number of coatings of different strength are applied to the fabric, the earlier ones being very thin so as to cause thorough impregnation. After vulcanization, for example by slowly raising the temperature to 285 or 295‹ F., the fabric may be treated with petroleum jelly, which may, if desired, be dissolved.

In addition, hot water can be passed through the pump from the discharge 4 to the intake 3. When the pump is started, valve 31 is .closed. If the pressure of the pump discharge is greater than that of the preheating water, valve 31 may be of the non-return type. In a modification, two inlets to the space 16, one on each side of a row of ribs 17, are provided at the bottom of the casing. Similarly, two outlets from the space 16 are provided at the top of the casing, in addition to or in place of the aperture 24. The inlet and outlet pipes are provided with valves. Each rib 17 may be of the full width of its guide ring, the throttling gaps being provided by staggering the ribs. The ribs may be provided on the casing.

The product is agglomerated immediately at the exit of the second stage and accumulated in a charging device such that temperature loss is minimized. The accumulated aggregates are then charging into an induction furnace containing a bath of ferrous metal; when smelting is complete slag is removed, and a quantity of metal tapped which is equivalent to the charge of agglomerates. As particularly described the initial reduction is carried out in a kiln 7 fired by a burner projecting deeply into the kiln from the discharge end, and supplied with fuel and air in such proportions that combustion is incomplete and a CO - containing gas is obtained . The downstream part of the kiln is cooled by cold air passing through the outer passage of the burner, and hydrogen is admitted thereto. The reduced product is discharged to briquetting rollers 6 and transfer buckets 4. A part of the effluent gas from the kiln is re-heated e.g. to 1000‹C in recuperator 26 and recycled through the central passage of the burner.
