Title: Improvements in or relating to production of coke
IPC: C10B55/10
Filed: 1951-12-05
Abstract: 703,805. Agglomerated fuel; coking heavy oil residues. STANDARD OIL DEVELOPMENT CO. Dec. 5, 1951 [May 5, 1951], No. 28517/51. Classes 50, 55 (1) and 55 (2). In a process for obtaining coke agglomerates from heavy oil residues and particulate coke or like carbonaceous solids the residues are injected into and at least partly coked in a vessel containing a fluidized bed of particulate coke and to which is fed a stream of coke particles of fluidizable size, for example 35-200 mesh per linear inch, the feed rate of the oil residues and the coke particles and the residence time of the solids in the vessel being controlled so that coke agglomerates are formed, coke agglomerates being continuously withdrawn from the vessel. The agglomerates have a size about 10-100 times the original size of the coke particles. The oil residues are fed to the vessel at a rate of 0.3-0.9 volumes per volume of unaerated solids supplied to the fluidized bed and a temperature of between 700-1050‹ F., preferably 800-900‹ F., is maintained within the vessel, the residence time of the solids in the vessel being between 0.5-5 hours and preferably 0.5-1 hour. The process may be combined with a process for coking and obtaining liquid distillates from heavy oil residues. Heavy oil residues and fine coke are supplied to a fluidized coking zone 1 through lines 9 and 3 respectively, fluidizing gases such as steam or gaseous hydrocarbons are supplied through line 5. The residues are coked at a temperature of between 900-1400‹ F., vaporous products and fluidizing gases leave by line 13 for recovery of liquid products or catalytic cracking and coke particles are withdrawn through line 19 and passed through line 23 to a fluidized agglomerating zone 25. The residence time of the coke in the coking zone is such that the particles increase in size by about 50-100 per cent. The temperature of the coking zone may be maintained by any suitable method, for example by continuously circulating heated solids between the coking zone and a separate combustion zone. The agglomeration zone 25 has the shape of an inverted cone and the coke particles supplied thereto through line 23 are fluidized in the middle and upper portions of the zone by gases, e.g. steam or an inert gas, preheated to about 900-1000‹ F. and supplied to the zone through line 29. Heavy oil residues, preferably preheated to about 500-700‹ F., are injected through line 31 and the agglomerates formed which are of such size that they are not fluidized under the conditions prevailing in the zone are withdrawn from the zone through line 35. Some of the agglomerates may be drawn off through line 43 and returned to the process after grinding. The heat for the zone 25 is obtained from the heat of the coke supplied from the coking zone but air or oxygen for partial combustion within the zone 25 may be supplied through line 45. Fluidizing gas and vaporous products are withdrawn through line 37 and treated for recovery of liquid products. Specification 593,418, [Group III], is referred to.

Title: New and improved anion exchange resins and their production
Inventor: ZENFTMAN HENRYK
IPC: C08F8/00
Filed: 1955-10-07
Abstract: Anion-exchange resins are prepared which consist of a polymeric ester made up at least substantially of units which contain at least one quaternary ammonium group connected to not less than two acyloxy groups each derived from acrylic or methacrylic acid and made by polymerization either before or after quaternization of esters of acrylic or methacrylic acid with polyhydric tert.-amino alcohols such as methylamine and ethylamine N,N-diethanols, methylamine N,N-dipropanol, triethanolamine, ethylenediamine N,N,N1,N1-tetraethanol, and 1:4-piperazine dimethanol and diethanol. Quaternizing agents specified are dimethyl and diethyl sulphates and methyl, ethyl and propyl chloride, bromide or iodide.  Polymerization of the ester may be carried in bulk or, preferably, in the presence of water if desired in suspension in a water-immiscible liquid, e.g. toluene, xylene and petroleum ether/carbon tetrachloride, and is accelerated by catalysts such as potassium and ammonium persulphates, benzoyl peroxide and azodiisobutyronitrile.  The ion-exchange resin thus produced may be in the form of beads or granules.  Alternatively the quaternary ester may be polymerized in the shape of a sheet or foil or while supported on a carrier of porous or felted woven fibre of material resistant to dilute acids and alkalis, e.g. glass or polyethylene terephthalate fabrics.  Specification 823,595, [Group IV (b)], is referred to.

Abstract: 464,413. Cathocle-ray tubes. KLEMPERER, O. Oct. 16, 1935, No. 28644. [Class 39 (i)] An electron-multiplier is provided with means for excluding from the electron beam all electrons having a velocity outside a predetermined range ; for this purpose the beam is deflected and passed through an aperture in a screen which stops all electrons deflected by more or less than a certain amount : the invention is stated to be especially applicable to the apparatus described in Specification 443,777. Fig. 2 shows an arrangement comprising a cathode 1, an accelerator grid 2 and a control grid 6. The electrons which pass an opening in a diaphragm 3 are deflected by arcuate plates 8 and 9 and these deflected to the desired extent pass through an opening in a diaphragm 5; dimensions and voltages of apparatus for separating electrons having a velocity of 20 volts. from those having a velocity of 20À3 volts are given. Other arrangements are described, one of which is shown in Fig. 4, in which the beam as a whole is not deflected. Electrons from the cathode 1 are accelerated and decelerated by electrodes 2 and 12 formed as cylinders with apertured ends and a disc 13 between the electrodes stops electrons not sufficiently deflected. The homogeneous beam produced may be modulated by causing it to pass through an apertured diaphragm and deflecting it in the ordinary way. Magnetic deflection may be substituted for electrostatic.

Title: Improvements in or relating to autoclaves
Inventor: COOPER WILLIAM CHARLES
IPC: F16J13/22
Filed: 1964-07-14
Abstract: A steam-jacketed autoclave (11) has an air-operated sliding door (13) which is sealed when closed by an inflatable seal housed in a groove around the door opening and interlocks which ensure that the door is fully closed before either the seal or the autoclave chamber are pressurized.  When the door is closed and sealed a delay cylinder operates, after a slight time-lag, the switch of a solenoid valve to give the first of a series of air pulses which operate a 30-position electrical rotary switch in a timer unit which controls the sterilisation cycle.  A vacuum pump (49) connected to the autoclave chamber is started up at the beginning of the cycle and runs throughout it.  In the cycle air is first evacuated from the chamber down to a vacuum of 25\yF of mercury at which point a pulse of steam (admitted at 55) raises the pressure in the chamber again to a slight positive value.  This sequence is twice repeated and then steam is admitted until a thermocouple in the draw line (64) shows 134 DEG F. After sterilisation filtered air is admitted at atmospheric pressure and a lamp indicates "cycle complete".  If the sterilization temperature is not reacted a flashing indicator comes on at the sterilisation stage and remains on.

Title: Improvements in or relating to filters and a filter-pressure regulating unit therefor
Inventor: KOVACS JULIUS PAUL
IPC: B01D35/147
Filed: 1952-11-19
Abstract: 727,609. Filters. PUROLATOR PRODUCTS, Inc. Nov. 19, 1952, No. 29206/52. Class 46. [Also in Groups XXVII and XXXIV] A filter and a filter-pressure-regulating unit therefor is adapted to be used in combination with an engine block having a main oil duct for delivery of lubricating oil under pressure from an oil pump to engine elements to be pressurelubricated, and a connecting,rod duct for delivery of oil to connecting rods, the ducts opening in a face of the engine block. Oil proceeding from the pump along a duct 13, Fig. 1, in an engine block 11 is diverted along a conduit 20 to a filter 32 from the discharge side of which it returns along duct 21 to a main oil duct 12 whence it reaches the main bearings and other parts. Low pressure oil is supplied to the connecting reds along a duct 14 by a restricted duct 42, Fig. 2, leading from the inlet conduit 20. A by-pass valve 47 is set to operate at a pressure such as 15 p.s.i. A filter relief valve 38, Fig. 1, is also provided to operate when the filter becomes clogged. In Fig. 5 incoming unfiltered oil rises up a central tube 58 from whose upper end it is discharged into the main body of a filter casing 49.

Title: Improvements in or relating to variable transmission gearing
IPC: F16H29/14
Filed: 1926-11-20
Abstract: 285,583. Crowsley, P. S. Nov. 20, 1926. Variable-speed gearing comprises clutches o', o<9> - - arranged coaxially with driving and driven shafts a, b and adapted to be thrust into engagement intermittently while rotating with cyclically varying speeds. A spider e fast upon the driving-shaft carries shafts d each having fast thereon a planet gear d<2> meshing with a sun gear o<3>, o<4>, or o<5>. The shaft d is caused to oscillate by a link connection f<3>, d<3> with the strap f<5> of an eccentric. The eccentric f<7> which is annular does not turn and is displaced eccentrically to vary the cycle of speeds of the sun gears o<3> &c. to which the clutch members o' &c. are secured. By means of a cam j<1> on the eccentric, through linkage d<1>, f', sleeve o, and gears o<1>, o<2>, a differential movement of cams o<6> is effected, which causes the periodic operation of the clutches. Instead of the sun and planet gear pairs, crank linkages may be used.

Title: Measuring changes in length of textile threads, webs or the like
IPC: B65H61/00
Filed: 1954-10-12
Abstract: 765,712. Testing yarns. SUCKER GES., GEB. Oct. 12, 1954 [Oct. 15, 1953], No. 29413/54. Class 120 (3). [Also in Group VIII] Changes in length of a textile thread are measured by comparing the lengths that run past two different measuring points during the same interval of time. In one arrangement, Fig. 4, measuring mechanisms 8, 9, arranged respectively before and after a treatment chamber wherein the material undergoes expansion or contraction, each include a measuring wheel 11 driving one half of a clutch 13. In mechanism 8, the clutch is controlled by a solenoid 15 and the driven half of the clutch is geared to a shaft 30 carrying cams 31, 32, 33. In mechanism 9, the clutch is controlled by a solenoid 37 and the driven half of the clutch is connected to a revolution counter 39. To start a measuring operation, a main switch 50 is closed and a push-button 18 depressed to close contacts 36 and energize solenoid 15, causing its clutch to engage and start camshaft 30 rotating; cam 33 now closes a holding circuit for solenoid 15 and cam 31 closes contacts 34 to energize solenoid 37 and start counter 39. This circuit is subsequently maintained by cam 32 closing contacts 35 and is broken, thereby stopping counter 39, when contacts 35 are opened. Shaft 30 continues to rotate to complete one revolution, when contacts 36 are broken again. By adjusting the relative settings of cams 31 and 32 the length of material measured by mechanism 8 is set at a standard length. The length indicated by counter 39 is compared with this standard length to determine the degree of shrinkage or stretch ; alternatively, the counter may be first set back by a count corresponding to the standard length, so that at the end of the measurement it gives a difference reading. In another embodiment, Fig. 6, the measuring wheels 11 act through cams 21 or 22 to close electric circuits one or more times per revolution. A counter 23 is actuated by a solenoid 51 and counts the number of impulses received from the first wheel 11 ; - a second counter 24 is actuated in opposite directions by solenoids 26, 27 connected respectively to the first and second measuring wheels, so that the counter indicates the difference between the numbers of impulses received from the two wheels. A solenoid 25 for re-setting the counters is actuated by a switch 41 as it is moved to the closed position to start a measuring operation. Comparison of the readings of the two counters indicates the degree of shrinkage or stretch. Counter 23 may be provided with a trip lever which opens a switch 28 to stop the measuring operation after a given number of impulses are registered on counter 23. Cams 21 and 22 transmit different numbers of impulses per revolution and are used selectively according to the speed of the material being measured. Counter 23 may be dispensed with, the difference reading on counter 24 being taken when a given length has passed one of the measuring devices.

[Class 110 (iii)] Gas turbine blades, or segments carrying blades, are made with shouldered shanks 20, Fig. 1, gripped between two turbine discs 10, 11 which are secured together by bolts or rivets 22 located radially outside the engaging shoulders 18. The discs are also secured together by a central sleeve 14 and nut 16. In Fig. 1, blades 23 have fir-tree roots secured in segments 28 formed with the shouldered shanks 20. In Fig. 3, each blade 52 has a shouldered shank 57. In Fig. 5, each blade 52 has a shank with shoulders 54, which lie radially inside the disc-fastening rivets 56, and additional shoulders 72. The turbine discs 10, 11, Fig. 1, have interfitting internal flanges 13, internal shoulders 34 defining an annular recess in which an aluminium ring 35 fits and abutting flanges 32. Cooling air passes through holes 17, slots 36 cut in the ring 35, holes 33 and slots 27, 25 cut in the shoulders of the shank 20 and the thickened portions of the turbine discs. The air passes out through slots 30 which open into the blade sockets and through slots 31 cut in the blade-carrying segments between the blade sockets. The' blades may be hollow and cooling air be passed through them. The turbine discs 40, 41, Fig. 3, have central flanges 44 which are bolted together and covered by a ring 47. The flanges and the ring have air passages 46, 48. The discs have two pairs of internal flanges 60, 66 against which aluminium rings 61, 67 fit and the rings have a number of slots 62, 68 to provide passages for cooling air. Adjacent sides of the blade roots are grooved to form clearance slots through which contacting lands 55 on the discs project. These lands determine the spacing of the discs and the blades may be fitted with a slight axial clearance. The grooves in the sides of the blade roots open into the rotor interior to admit cooling air to the slots. Cooling air is also guided over the exterior of the discs.
