Title: Improved hydrocarbon conversion process
IPC: C10G11/18
Filed: 1945-05-24
Abstract: <PICT:0602471/III/1> In a hydrocarbon conversion process, e.g. catalytic cracking, in which hydrocarbon vapours are contacted in a reaction zone 10 with a fluidised mass of contact particles which are regenerated by burning in a zone 108, the fouled particles from the reaction zone are passed to a separate stripping zone 68 which is maintained at a higher temperature than the reaction zone by the passage thereto of hot regenerated contact particles from the regeneration zone. Contact particles, after a preliminary stripping in annular zone 44, leave the reactor through line 56, mix with regenerated material from line 72 and pass through line 66 to the stripper; stripping gas, such as steam, flue gases, nitrogen, or carbon dioxide, is introduced at 78.  The remainder of the regenerated material passes through line 16 and mixes with the feed introduced at 14.  Stripped particles from the zone 68 are mixed with regeneration gas led in at 116 and flow through line 114 to the regenerator 108.  The stripping gases leave at 94 and may be mixed with the reaction products either above the dense phase in the reactor or in line 38, or may be separately treated to recover hydrocarbons and catalyst.  An oxygen-containing gas, such as air, may be introduced into the stripping zone to increase the temperature therein.  Grids, baffles, or perforated partitions may be provided in the stripper.  The temperatures in a cracking process may be 800 DEG -950 DEG  F. in the reactor, 900 DEG -1000 DEG  F. in the stripper, and 950 DEG -1100 DEG  F. in the regenerator.  The temperature in the regenerator may be controlled by a cooling coil immersed in the dense bed, or by passing part of the contact material through a cooler and back to the vessel.  The process is also applicable (Fig. 2, not shown) in conversions where the contact material is carried upwardly by the vapours out of the various zones and separated in cyclone separators.  Contact particles separated from the reaction products are maintained in the fluidised state in a hopper into which hot regenerated contact material may be led.  Part of the stripped contact material may be passed back to the reactor.

Title: Improvements in and relating to the production of hydrosine
Inventor: HARDING ANTHONY JOHN
IPC: B01J19/08
Filed: 1960-04-13
Abstract: <PICT:0958777/C1/1> In a method for producing hydrazine from ammonia, a gaseous phase is subjected to an electric discharge at a frequency in the range 1 to 300 mc./sec., in the presence of a liquid phase. The liquid may be anhydrous ammonia at - 70 DEG  C. or a solution of ammonia in water at - 50 DEG  to O DEG  C. or higher if it contains ammonium nitrate or calcium chloride.  The liquid may be present in the discharge chamber as a mist or a pool, or a vertically or helically falling layer of liquid on the chamber walls, or may be injected in the form of droplets as described and claimed in Specification 958,776. The gaseous phase may contain ammonia or may consist predominantly of argon.  The total gas pressure may be 5 to 100 mm. of Hg, at a temperature below 1300 DEG  C., the field strength 25 to 1500 volts per cm., and the current density below 0.5 amp. per cm. The electrodes may be of platinum, tungsten, nickel, stainless steel, or nickel- or chromium-plated copper or copper alloys, and may be hollow for the circulation of cooling fluid. Preferably, at least one electrode is immersed in the liquid which then contains an electrolyte, e.g. ammonium nitrate. The may be imposed on the discharge a further electric field whose polarity is constant or alternates at a frequency of at most 1 mc./sec. As shown, the discharge chamber 1, comprising electrodes 2, 3 and an inlet 4 for gas or liquid, is mounted in a cooling jacket 6 surrounded by a re-entrant coaxial resonator for the input of the high-frequency alternating current. Specific examples of the preparation of hydrazine from ammonia are given.  According to the Provisional Specifications, hydrogen peroxide may be produced from water by similar methods. Specification 958,778 also is referred to.

Patent GB-351160-A (GB)
Title: Process for the purification of the juices of sugarworks and of refineries
IPC: C13B20/06
Filed: 1930-05-01
Abstract: Sugar factory and refinery juices are purified by adding lime to the juice at the known optimum temperature in amount sufficient to make the juice alkaline to an extent in excess of the alkalinity corresponding with the pH value which characterizes the isoelectric point of the colloids in the juice and then introducing sulphur dioxide preferably in the liquid state, or its equivalent, in amount sufficient to bring the alkalinity to that connoting the said zone. The flocks formed may be separated at this point by filtration.  A small addition of lime is then made for subsequent carbonation.  The first addition of lime may be made by adding juice which has already been subjected to the process and subsequently treated with lime. The addition may be made in the course of the diffusion process, i.e. in the last vessel of the diffusion battery.

Title: Improvements in machines for reproducing perforated pattern cards
IPC: D03C17/00
Filed: 1926-05-28
Abstract: 252,734. W³rker Ges. May 29, 1925, [Convention date]. Cards and the like, punching.-A machine for reproducing perforated pattern strips or cards comprises a guide-frame 1 - - 3, Fig. 3, mounted for vertical sliding movement in a frame M by means of pins 4, 5 controlled by springs 6, 12. The original strip O and the blank V are fed over the guide-plates, 2, 3 by pins 16, 17 on a horizontally-reciprocating feed-bar 23, which works in slots in the guide-plates. Upper guide plates 11, 13 are variably pressed by springs 12, 15 on the strips in accordance with the position of the guide-frame. The springs 15 act upon a punch guide-block 14 en the plate 13, lugs on which impinge on frame-blocks A to raise the plate 13 slightly when the feed is to take place. The guide-frame carries a roller 7 supported on or positively controlled by a cam disc 9, which also actuates a lever 24 to reciprocate the feedbar 23. The feed-bar is supported by a lever 27 which has pin-and-slot engagement 21, 23 with an arm thereon and is normally held by a spring 29 against a stop 30. The lever 27 can be thrown over against the stop 31 to lower the pins 16, 17 and allow the strips to be changed. Platens 32 are slidably mounted in the frame M above the original strip, and carry pins 33, which register with holes in the guide-plates 2, 11. Punches 37 are slidably mounted in the block 14 and have hooked upper ends, which take over a stop-bar 38 on the frame. Starting from the position shown in Fig. 3, rotation of the cam 9 first shifts the feed-bar to the left to feed the strips forward; the cam then raises the guide-frame, so that the pins 16, 17 are disengaged from the strips and the platens are either raised by the strip or pass through the holes therein. Further rotation of the cam shifts the feed-bar to the left again so that a locking-bar 44 carried thereby engages between upper and lower inclined surfaces 40, 41, Fig. 7, on the stationary and raised platens to lock the former against rising. The guide-frame is again raised so that the locked platens force the corresponding punches 37 through the rising strip V, Fig. 9, and perforate it in accordance with the strip O. The feed-bar is returned to its original position and the guideframe is then lowered, a bar 36, carried by the guide-frame and the stop-bar 38 returning the platens and punches respectively to their original positions. The machine punches the marginal perforations as well as the pattern-holes. To allow for wear in the marginal perforations of the strip 0, the pin 16 is adjustable on the feedbar.

[Also in Division G1] In a weighing apparatus in which endless belts 78, 180 convey articles one-by-one to a scale platform 80, the deflection of the scale platform 80 due to the weight of an article it supports is sensed by electromagnetic switches S 1 -S 4  which are so connected to electromagnetic relays in a circuit employing a photo-electric cell that deflectors are electromagnetically operated to direct the weighed article from the platform 80 in one of three directions according to whether the article is underweight, overweight or of acceptable weight. The circuit (Fig. 33) is arranged in such a way that first electromagnetic relays are energized due to the deflection of the platform and other relays are energized due to the article being weighed passing on the scale platform across a light beam associated with the photoelectric cell PC. Condensers and resistances are connected in parallel with some of the relays to affect their energization in such a way that the deflectors which are solenoid-actuated are suitably operated.
