Title: Improvements in cycle brakes
IPC: B62L1/16
Filed: 1948-11-11
Abstract: 648,040. Cycle brakes. CLARKE, C. A. Nov. 11, 1948, No. 29298. [Class 136 (i)] A cycle brake of the calliper type is operated by means of a wedge member g disposed between two swivelling blades h<SP>2</SP> integral with the pivoted brake levers h, floating rollers I being inserted between the sides g<SP>1</SP> of the wedge member and the adjacent edges h<SP>3</SP> of the swivelling blades so that upon advance of the wedge member the floating rollers are displaced in the direction of said advance but at a slower rate of travel. The brake levers h are pivotally mounted on studs i secured in curved arms a<SP>1</SP> of a back plate a and are pressed apart by a coiled spring j, the blades h<SP>2</SP> thus being pressed towards one another. The rollers l are fitted on pins l<SP>1</SP> connected together by a coiled tension spring l<SP>2</SP>. Washers l<SP>3</SP> are fitted over the pins so as to overlap the blades h<SP>2</SP> and wedge g and maintain the rollers in place during the travel of the wedge member. The edges h<SP>3</SP> of the blades converge towards the tapered sides of the wedge in the normal position but become parallel and eventually reverse the relative inclination as the blades swivel upon the pivots so that the velocity ratio of the mechanism gradually increases as the brake is applied. Stops g<SP>2</SP> are provided on the wedge member g to limit the travel of the rollers l. In a modification, Figs. 5 and 6, a member n is provided formed as two wedges. Swivelling blades o have slots o<SP>1</SP> into which are fitted duplex rollers having heads p and a middle portion p<SP>1</SP> of smaller diameter engaging in the slot o<SP>1</SP>. Openings o<SP>2</SP> lead into the slots and admit the portions p<SP>1</SP> of the rollers.

Title: Electronic tube functioning as an oscillator by the effect of interaction between several electronic streams of different velocities
IPC: H01J25/48
Filed: 1950-12-05
Abstract: 714,755. Space charge wave tubes; magnetron oscillators. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 5, 1950 [Dec. 23, 1949], No. 29714/50. Class 39(1) An electronic oscillator comprises two concentric cylindrical electrodes 1, 2, Fig. 2, which are non-resonant and have different DC potentials to set up a radial electric field, the more negative electrode (2 as shown) having an aperture housing a cathode 3 and focusing electrodes 4, the beam so generated circulating in the annular space under the influence of the radial electric field and of a time constant magnetic field in the plane of the paper, a second aperture being provided in one of the electrodes (1 as shown) associated with means 10 for extracting high frequency energy, the ratio of the electric and magnetic fields varying in the radial direction. Copper electrode 1 is at earth potential and has covers 6 to form the envelope and relatively negative electrode 2 is carried by insulators 7. Cathode 3 and focusing electrodes 4 are fixed to bars 8 (only one shown). Energy is extracted by a flat helix 10 connected to coaxial line 11. The electric field varies radially the magnetic field between hole pieces 12 being constant. In another form, Figs. 3, 4 (not shown), the inner electrode is relatively positive and two cathodes and sets of focusing electrodes are housed in an aperture in the outer electrode. The output is taken by a coupling loop, and the pole pieces are shaped to obtain a radially non-uniform magnetic field. In a modification, Fig 5 (not shown), the output coupling loop is in the plane of the electrons and the inner electrode is hollowed out at its centre to form cooling fins which are exposed to an air stream. In another form, Fig. 6, the output energy passes through slot 10 and horn 11 to guide 13. The pole pieces 12 are recessed so that the magnetic flux traverses only the annular space and cooling fins 16 for electrode 2 are housed in one of the recesses. The frequency is varied by varying the voltage of the cathode, cylindrical electrodes, or the magnetic field. The operation is generally similar to that described in Specification 692,705.

Title: Improvements in self-acting mules and twiners
IPC: D01H3/12
Filed: 1923-11-28
Abstract: 222,711. Pickford, J. Nov. 28, 1923. Mules and twiners.-To allow free movement of the slide block 10, Fig. 1, during the outward run the boot-leg 1 is, in its lowest position, held out of contact with the slide block by an adjustable stop 5 on the carriage frame 3 engaging an extension 7 of the stud connecting the usual link 8 to the boot-leg 1. The stop 5, Fig. 6, may be mounted on a pivoted bracket 12. When rising the face 2 of the boot-leg 1 rests against the adjustable block 18 mounted on the slide block 16. The face of the block 18 terminates in a curve 25 to allow the boot-leg to move slightly towards the tin roller. This movement gives a preliminary movement to the backing-off charging-rod and causes the collar to come into actual. contact with the backing-off lever before the completion of the backing-off, and further slackens the backing-off chain and allows a more gentle locking of the winding-faller. To prevent lifting of the slide block 27, Fig. 3, when the boot-leg 39 presses against it and is being drawn upwards, the slide block has adjustably secured to it a bracket 28 to which is pivoted an arm 33 carrying a horizontally projecting block 34 against which the vertical face 40 of the boot-leg can ride. The block 34 carries a pivoted catch 35 with a tooth 36 adapted to engage teeth 37 on a stationary bracket 38. In its lowest position, an extension of the stud 43 connecting the usual link 44 with the boot-leg engages a stop 41 and the catch 35 is held out of engagement with the teeth 37, and the slide-block is free to rise and fall. When the boot-leg begins to rise, the stops 41 and 43 come out of register and the boot-leg rests against the block 34 and moves the arm 33 to carry the tooth 36 on the catch 35 into engagement with the teeth 37. This locks the slideblock and prevents it from rising with the bootleg. When the boot-leg is in its highest position it rests on the block 34 and this causes the arm 33 to move about its pivot and release the catch 35. The catch 35 and arm 33 are provided with suitable stops to limit their movements.

Title: Improvements in the manufacture of phosphoric acid
Inventor: WILLIAMS THOMAS ALAN
IPC: C01B25/235
Filed: 1964-07-28
Abstract: Phosphoric acid prepared by the wet-process from sedimentary phosphate rock containing organic impurities which are soluble in phosphoric acid, is purified by passing it, after the main gypsum filtration at above 60 DEG  C., through a bed or column of sufficient active carbon, e.g. at least 5%, preferably 10%, by wt. of the P2O5 content of the acid, to remove the organic impurities. A flocculating agent may be added before the acid reaches the main gypsum filtration to assist the settling of the carbon. The carbon may be regenerated by caustic soda, which may be passed in the opposite direction to the acid at a rate sufficient to dislodge but not carry away the granules.  The acid treatment may be effected in two counter-current stages. Condensed alkali metal phosphates may be made by calcining orthophosphates made from this phosphoric acid.

Title: Vane type rotary positive displacement machine
IPC: F01C1/344
Filed: 1974-07-10
Abstract: 1478347 Rotary positive-displacement vanetype machines ABEX CORP 10 July 1974 [3 Oct 1973] 30661/74 Heading F1F Each vane of a rotary positive-displacement machine is constructed so that in the transfer zone, Fig. 4, differential pressure on the vane 42 due to high and low pressures P, S, Fig. 8, causes the vane to tilt and consequently engage its slot to create a reaction force C, this force having an outward component D which overcomes the inward force A arising from high pressure P acting on a bevelled portion 67 of the vane tip, low pressure S acting on the rest of the vane tip and being transmitted to the bottom of the vane via passage 44 in the rotor. The desired outward component depends on the angle of surface 63, Figs. 6 and 8, relative to the plane of the leading face 58 on which the high pressure P acts, i.e. the greater the angle, 2 degrees in Fig. 6, the greater the component force D. In the sealing zone, Fig. 4, high pressure P acts via passage 44 on the bottom of vane 42 to urge it out wards (see also Fig. 9, not shown). An alternative embodiment, Figs. 5, 10, 11, 12, 13, (not shown) describes a vane which will rely on the reaction force in the sealing zone and high pressure biasing in the transfer zone. A vane with two bevelled sealing lips on its tip is also described Figs. 14 to 16, (not shown) and here a reaction force is used for outward biasing in both the sealing and transfer zones.

Title: Condensation of phthalic anhydride
Filed: 1964-08-04
Abstract: 1,057,422. Condensation of phthalic anhydride vapour to the solid state. UNITED STATES STEEL CORPORATION. Aug. 4, 1964, [Aug. 7, 1963], No. 30863/64. Heading BIB. [Also in Division F4]  Phthalic anhydride is condensed to the solid state from a gas, containing phthalic anhydride in vapour phase, by passing the gas between parallel or converging condenser surfaces, the gas having a Reynolds number of at least 12,000. The operation is carried out so that there are no fine solid particles in the effluent gas. As shown, the gas is passed between cooled hollow plates, 12,14 ... 24,26 which converge in the direction of gas flow, and the phthalic anhydride vapour condenses to the solid state on the plates. The cooling-fluid, e.g. oil or water, is introduced into the plates through manifold 40, and is withdrawn from the plates through manifold 56. The temperature-difference between the gasstream and the cooling-fluid may be 70 to 100C. depending on the rate of gasflow. If needles of phthalic anhydride are blown off the deposit on the plates, they may be collected on a steel wool plug in the condenser outlet. The inlet temperature of the gas is about 130C., and the outlet temperature is 45 to 65C. The effluent gas contains all the water and maleic anhydride vapour present in the inlet gas. Several banks, e.g. four, of tubes may be joined in series, the distance between the plates decreasing, gradually or step wise and from bank to bank. The coolant leaving one bank can be employed as coolant in. another bank wherein the gasstream has a higher temperature than in the first bank. Alternatively, each bank has an independent coolant system. In order to remove the deposit of phthalic anhydride from the plates, warm fluid is passed through them whereupon the anhydride melts, and is readily discharged from the base of the condenser. It is stated that concentric cones may be used instead of flat condenser plates.
