Title: Improvements in type line composing and casting machines
IPC: B41B11/00
Filed: 1934-08-03
Abstract: 430,613. Type-bar-making machines. INTERTYPE CORPORATION, 360, Furman Street, Brooklyn, New York, U.S.A. Aug. 3, 1934, No. 22708. Convention date, Jan. 26. [Class 100 (iii)] Assembling matrices; driving-mechanism.- To adapt the machine for casting either from lines of ordinary matrices, which are afterwards distributed, or from hand-set lines, which are not distributed, means are provided for imparting two different cycles of movement to the transporter, in one of which the line, after the casting, is brought to a line-removing position which is different from the normal, and may be the same as the line-receiving position. The transporter is operated by either of two cams, one of which effects the usual cycle, consisting in lowering the transporter from the receiving to the casting position, raising it to the line-removing position, and lowering it again to the receiving position. The second cam has the high part 17, Fig. 4, that raises the transporter to the line-removing position, replaced by a lower portion 18, which may be concentric with the portion 15, that sustains the transporter at the line-receiving position, so that, after the casting of a hand-set line, the transporter is returned to a position in which the line may be removed by hand. The two cams operate levers 20, 22, Fig. 1, mounted on a shaft 13, an arm 11 on which actuates the transporter 5. The lever 22, belonging to the cam that effects the normal cycle, is loose on the shaft 13, and can be connected to the lever 20, which is fixed on the shaft, by a pivoted latch 25. The latch is operated by a toggle 28 and a rod 34, which extends towards the front of the machine and is engaged by a hand lever 35. After the casting of a line from hand-set matrices, during which the latch 25 is disengaged, and the transporter is operated by the second cam and the lever 20, the latch is automatically reengaged by the action of the ejector-lever before the next cycle commences. At the end of each cycle, the machine is stopped by the usual stopping-levers 48, 49, which are carried by the starting-lever 46, and are acted on by a pawl 50 pivoted on one of the cams on the main shaft, in order to disengage the driving- clutch. The operation of the hand lever 35 to withdraw the latch 25 may also serve to re-start the machine by means of a connection to the usual starting-handle. The head 8 of the transporter is connected to the lower portion by a pivot 9, so that it can be swung forwards to facilitate the introduction or removal of a line.

Title: Improvements relating to the production of coatings on ferrous surfaces
IPC: C23C22/74
Filed: 1951-09-28
Abstract: A dilute aqueous solution of a non-metallic acid or acid-reacting salt is applied to a ferrous surface so as to form a film on the surface without any substantial chemical reaction taking place between the surface and the acid or salt, the film is allowed to dry at least partially at atmospheric temperature to form a layer of an oxidisable ferrous salt, and, without washing or heating in air, the surface is treated in an airconditioning chamber with an oxygen-containing atmosphere having a relative humidity of at least 60 per cent.  The acid is preferably hydrochloric or sulphurous, but sulphuric or phosphoric acid or a salt such as ferric chloride or chromium chloride may be used. The solution may also contain an accelerator such as a sulphite or thiosulphate or formic acid, and a hydroscopic substance such as glycerine or calcium chloride.  A layer consisting mainly of hydrated ferric oxide is formed, which facilitates cold working. Specification 455,077 is referred to.

Title: Improvements in the manufacture and production of carbon black
IPC: C09C1/54
Filed: 1930-07-28
Abstract: In the catalytic decomposition of gaseous or vaporous carbon compounds to form carbon black, clogging of the apparatus by the carbon formed is prevented by forming the reaction chamber of or coating the inner walls with a metallic material which produces no appreciable decomposition of the materials treated.  Unmasked iron, cobalt or nickel is excluded from the formation of the inner p  walls which are made as smooth as possible; scrapers, conveyers, brushes, &c., are made of similar materials.  The metals employed include silver, copper, chromium and their alloys such as bronzes, brass, copper-manganese, nickel-chromium alloys, chromium or chromium-nickel-molybdenum steels, ferrosilicon and nitrated steels. The gases treated include saturated and unsaturated gaseous hydrocarbons, oil and cracking gases, and the oxides of carbon singly or in mixture or including small amounts of extraneous gases such as hydrogen or water vapour.  Atmospheric, reduced or increased pressures may be employed.  As catalysts, iron, nickel, cobalt or their oxides may be used alone or mixed with activators such as zinc oxide.  An example is given of the treatment of ethylene. Specifications 325,207 and 327,374, [both in Class 90, Non-metallic elements], are referred to.

A crush trueing apparatus for a grinding wheel 15 comprises a pair of backing rolls 92 for transmitting the load from a crushing roller 61 to a supporting slide 41 during a crush trueing operation. The backing rolls are rotatably mounted on shafts 91 secured to the slide which is movable towards and from the grinding wheel along guideways 43 on a slideway 42 adjustably secured about a pivot 54 on the grinding wheel slide 11 to permit parallel alignment of the crushing roller with the grinding wheel. The slide 41 has a pair of cylindrical openings 66 slidably receiving rods 65 supporting vertically adjustable blocks 63 having pointed screws 62 engaging the ends of the crushing roller. The slide 41 is movable towards and from the grinding wheel by a screw 114 which engages a nut 112 on the slideway 42 and is connected to the piston 111 of a device 110 having a cylinder connected to the slide 41, the arrangement being such that fluid pressure supplied to the device 110 advances the slide 41 first at a rapid and then at a slow speed. The screw 114 is rotatable by gearing 128, 129 and a shaft 131 connectible by gearing 102, 103 and an overrunning clutch 150 to a hand wheel 101 for initial adjustment of the slide. The clutch is also connected by a pin 155 to a piston 141 which is movable against a spring 142 by fluid pressure supplied to a port 144 to advance the slide incrementally a distance determined by an adjustable stop 145 after each trueing operation to compensate for the reduction in size of the grinding wheel after each trueing operation. The grinding wheel, which may be profiled to grind the roll W of a rod rolling mill, is mounted on a spindle 14 connected by a belt 21 to the shaft 18 of a motor 17. The shaft 18 is provided with a brake 35 and is connected by a belt 29 and speed-reducing gear to a motor 22. In operation, the grinding wheel is rotated at high speed for the grinding operation. When it is desired to true the wheel, the wheel is retracted by movement of the slide 11 on guideway 13 and the motor de-energized and stopped by the brake 35. Thereafter, the brake 35 is released and the motor 22 energized to rotate the grinding wheel at low speed and fluid pressure is supplied to the device 110 to advance the crushing roller into engagement with the grinding wheel. Brushes 77 and a diaphragm 81 keep the crushing roller and backing rolls clear. The crushing roller may be easily exchanged by withdrawing the rods 65 from the openings 66, the rods being releasably retained in the openings by screws 161 engaging slots in the rods. In an embodiment in which the crushing roller does not have a substantial area of constant diameter, the roller has spaced portions beyond the operative portion for engagement with the backing rolls. The trueing slide may be mounted for vertical horizontal or other movement radial to the grinding wheel.

Title: Improvements relating to the catalytic cracking of petroleum hydrocarbons
IPC: C10G69/04
Filed: 1951-10-03
Abstract: <PICT:0737085/III/1> Sulphurous petroleum fractions boiling in the wax distillate boiling range are hydrofined by contacting the fraction in the presence of hydrogen and at a temperature of 780 DEG F. and a pressure of 1000 p.s.i.g. with a catalyst consisting of the combined oxides of cobalt and molybdenum deposited on alumina; the hydrofined fraction is then subjected to catalytic cracking.  An alternative embodiment comprises subjecting to catalytic cracking a feedstock boiling in the wax distillate boiling range obtained from a hydrofined crude petroleum oil.  A synthetic silica-alumina or silica-magnesia catalyst may be used in the cracking stage, or a natural cracking catalyst may be used.  Wax distillate (B.R. 280-580 DEG  C.) containing 1.7 per cent sulphur is passed through line 10 into heater 11, where it is heated to 750 DEG  F.  The oil is then mixed with recycle gas stream, containing hydrogen, leaving heater 12 via line 13 at 1100 DEG  F.  The combined oil/gas stream, which has a temperature of 800 DEG  F., is passed through line 14 into chamber 15 which is filled with bauxite to remove vanadium and sodium from the oil.  The oil/gas stream is then passed into reactor 16 which contains cobalt molybdate at 780 DEG  F.  The products from the reactor are passed to hot separator 18.  The separated liquid (containing only 0.06 per cent sulphur) is taken via line 19 to the bottom of pipe 47 where it picks up hot regenerated silica-alumina catalyst from regenerator 24; the mixture then flows into reactor 21 where the catalyst is maintained as a fluidized bed at a temperature of 930 DEG  F. Entrained catalyst is separated from the reaction products in cyclone 25; and the products are passed via line 26 to fractionating tower 27.  Settled slurry from the base of tower 27 is returned to the reactor via lines 28 and 19.  Decanted oil from the top of the settling section of the tower is withdrawn via line 29; and heavy and light gas oils are taken off as side streams via lines 30 and 31 respectively and steam strippers 32.  Gas and gasoline are taken overhead to separator 34 from which gas and liquid streams are taken via lines 35 and 36 respectively to the gas recovery plant, some liquid also being returned to tower 27 as reflux.  The yield of gasoline is 45 per cent.  The vapours from hot separator 18 are passed via cooler 39 to cold separator 40 from which liquid is passed to tower 27.  The gases from separator 40 are scrubbed in scrubber 43 with lean oil from the gas recovery plant.  Hydrogen-enriched gas from scrubber 43 is recycled to reactor 16 via line 45; and the rich oil is returned to the gas recovery plant via line 46. Specifications 632,193 and 653,320 are referred to.

Title: Improvements in or relating to control systems
IPC: H02P1/56
Filed: 1947-08-22
Abstract: 642,327. Automatic control systems for physical variables. ASKANIA REGULATOR CO. Aug. 22, 1947, No. 23356. Convention date, Aug. 24, 1946. [Class 38 (iv)] In a control system for a variable a controlling signal opposing the correcting signal is applied during deviation of the variable from a predetermined value and is removed at an adjustable rate by apparatus the operation of which is initiated by the controlling signal. As shown in Fig. 1 a valve 6 under the control of a motor 7 is adapted to control the pressure in a conduit 5. The motor 7 is controlled by signals from three devices 11, 9 and 16. The first device 11, produces a signal corresponding to the predetermined value at which the variable is to be maintained. The second device 9, produces a signal equal in magnitude but opposite in character to that of the device 11, when the variable is at the predetermined value, but this signal increases or decreases in magnitude if the variable varies in one direction or the other, to produce a resultant signal which is applied through a control circuit 15 to the motor 7 and is of a magnitude corresponding to the degree of departure from the predetermined value of the variable, and of a character corresponding to the direction of departure. The third device, shown as a bridge 16 fed by a fixed source of potential 19, is arranged to counteract or offset progressively the resultant signal produced by the devices 9 and 11. The bridge 16, normally balanced when the variable is at the predetermined value, comprises resistors 17 and 18 tapped by contacts 20 and 21 respectively. The contact 20 is driven by the motor 7 causing an unbalance of the bridge upon deviation of the variable from the predetermined value. The output is applied through a transformer 23 and potentiometer 26 to the control circuit 15 in a sense to offset the combined signal due to the devices 9 and 11. The out-of-balance voltage is also applied to a control circuit 36 actuating a motor 32 which moves the contact 21 through variable transmission 33 so as to rebalance the bridge and remove the offsetting voltage. In a modification, Fig. 2 (not shown), in place of the fixed source of potential 19 a source of variable potential, itself operated by a device similar to the device 16, is employed so that the potential applied to the bridge 16 is decreased as the contact 20 is moved from its neutral position. Thus for large deviations of the variable only a small offsetting voltage is initially generated. In a further modification, Fig. 3 (not shown), the offsetting voltage is derived from two devices similar to the bridge 16 and is such that an aiding signal may initially be obtained in the case of large deviation of the variable.
