Title: Process for the recovery of low boiling hydrocarbons
Inventor: SCHMIDT JOSEF
IPC: B01D53/14
Filed: 1956-05-07
Abstract: Gaseous hydrocarbons are recovered from gases containing them in low proportion by absorbing the hydrocarbons under pressure in a liquid solvent, the hydrocarbons then being separated by reducing the pressure in at least three stages in the first allowing undesired gases to escape together with limited quantities only of hydrocarbons and recycling these to the absorption, in the second releasing the pressure to about atmospheric, in the third reducing the pressure by pump to below atmospheric pressure the products from the latter stages being combined and fractionally distilled and the absorption medium being recycled.  Preferably each stage of pressure reduction particularly the first two stages is subdivided into a plurality of pressure drops, and in the final stage the gases are strongly cooled before passing through the pump.  Also part of the absorption liquid may be diverted, after the final or earlier stage of pressure reduction freed of sulphur-containing impurities and recycled to the head of the absorption column, the portion of the liquid which is not so diverted being returned to the absorption column at a lower level. Specified absorption solvents are benzene and toluene.  In an example C1-C3 hydrocarbons are recovered from a coke oven gas by absorption in benzene.ALSO:Gaseous hydrocarbons are recovered from gases containing them in low proportion by absorbing the hydrocarbons under pressure in a liquid solvent, the hydrocarbons then being separated by reducing the pressure in at least three stages in the first allowing undesired gases to escape together with limited quantities only of hydrocarbons and recycling these to the absorption, in the second releasing the pressure to about atmospheric, in the third reducing the pressure by pump to below atmospheric pressure the products from the latter stages being combined and fractionally distilled and the absorption medium being recycled.

Title: Improvements in or relating to the production of aryl-substituted borazoles
IPC: C07F5/02
Filed: 1962-04-13
Abstract: Aryl-substituted borazoles are made by reacting a b -haloborazole, wherein any substituents other than halogen are hydrocarbon groups free from non-aromatic unsaturation, with a Grignard reagent in the presence of an ethereal solvent, the borazole starting material, the Grignard reagent, or both containing an aryl group, heating the product of the reaction in the presence of a substantially anhydrous hydrocarbon solvent of higher boiling point than the ethereal solvent so as to distill off the ethereal solvent.  Suitable solvents include benzene, cyclohexane, toluene, n-heptane and xylene. Preferably 0.5 to 1 part of solvent is employed for each part by weight of ether, but larger amounts can be used. The hydrocarbon solvent can be added before or after the reaction but should be present prior to the removal of substantial amounts of the ether.  Preferably the hydrocarbon solvent is continuously added to the reaction mass while the ethereal solvent is being removed.  Suitable ethereal solvents are diethyl ether, tetrahydrofuran, diglyme and dioxam. Detailed examples give the preparation of b -triphenylborazole, b -triphenyl -N-trimethylborazole and hexaphenylborazole.

Filed: 1973-03-27
Abstract: 1423053 Levitated systems HITACHI Ltd 27 March 1973 [28 March 1972] 14601/73 Heading B7L [Also in Division H2]  In an arrangement wherein a magnetically levitated linear synchronous motor vehicle 1 is propelled along a track-way EP through the interaction between steady currents in superconducting vehicle field coils 5A, 5B and propagating three phase currents in sequentially energized track-way coils 7, it is found that the dynamic stability is greatest if:- where 2a is the width of an "effective coil" constituted by the lower extremities of the coils 5A, 5B, 2b is the width of the coils 7 and g is the distance between coils 7 and the "effective coil". The levitation is produced by the interactions between steady currents in superconducting vehicle coils 4A, 4B and currents induced in short circuited coils or conducting sheets 8A, 8B on the track. Lateral guidance is achieved using similar short-circuited coils/conducting sheets 6 vertically arranged on the track. In the embodiment of Fig. 6 (not shown), vertical superconducting coils (9A, 9B) interact with vertical short-circuited coils or sheets (10A, 10B) on the track to produce levitation and guidance, whilst further coils (11) are influenced by track coils (12) for producing drive. In the embodiment of Fig. 7 (not shown), the vehicle incorporates vertical coils (13A, 13B) for reacting with vertical drive coils (14A, 14B) on the track.

Title: Arrangement for switching on and initiating processes by means of telephone calls
IPC: H04M1/652
Filed: 1945-06-08
Abstract: 624,687. Electrical signalling systems. BAKER, E. W. (Ipsophon Patentges. Akt.- Ges.). June 8, 1945, No. 14613. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 12, 1946.] [Class 40 (i)] [Also in Group XXXIX] Arrangements at a telephone substation for switching apparatus under the control of an incoming telephone call, but only if impulses transmitted by the caller occur at the correct times, comprise a first relay J28 which responds to impulses received over the line 13, 14 ; a second relay P98, operated by the cam-controlled contacts 74 to 83 at intervals determined by the setting of the switch buttons T1 to 10 ; and a third relay S27 which operates when the first two relays are out of synchronism to open the operating circuit of the switching relay AN96. Calling current brings up relays R4, H6 and ST12, the last of which connects up relay T57, and magnet VK62, which starts the drive for the magnetic sound record T033, and the cams NK1 to 18. The caller is thus connected to the output of the magnetic pick-up SPK100 which transmits a series of spoken numbers recorded thereon. The procedure for correct operation is predetermined by pressing certain of the buttons T1 to 10, say T1, T4 and T6, to cause operation of P98 by cams NK1, 4, and 6, so that operation by the caller of J28, after the transmission of the numbers 1, 4 and 6, is necessary for operation of AN96. Cam NK17 brings up U49 between the transmission of numbers to connect the caller to amplifier VEG32 and relay J28. The caller transmits two impulses, the first bringing up L50, followed by C48 at the end of the impulse, while the second impulse, since P98 is operated over NK1, brings up X24 which holds when P98 goes back. When P98 subsequently re-operates over NK4 and 6, a pair of impulses from the caller is required in each case to bring up X24. Finally, AN96 operates over NK11 to effect the desired switching. At a certain point, K69 operates over NK12 and locks under the control of of AN96. If the latter operates correctly, K69 falls back and H6 is released, when the cams have made a complete revolution. If AN96 fails to operate through the caller sending impulses not in accordance with the code, K69 remains held and in the normal position, if the cams brings up ST12 to repeat the cycle of operations, thus giving the caller a second opportunity of sending the code of impulses. Relay Z65 then becomes operated over NK13 and prevents a second repetition. Transmission of impulses by the caller at an incorrect time (when P98 is back) brings up S27 instead of X24. This relay locks, opens the circuit of AN96 and prepares a circuit for AB97 over NK11 for sending busy tone. Moreover, a condenser 104, charged while P98 is up, discharges on its release through S27 if X24 is not up and thus operates S27 if the caller fails to send impulses at the correct times.

[Class 65 (i)] In door-operating apparatus comprising a motor such as a differential fluid-pressure engine 7, 8, the motor is energized to open the door when the latch 51 is released and actuates the motor-control means. When the door is closed, the left end of the large cylinder 7 is open to exhaust, so that, when 51 is released, the unbalanced pressure between the two pistons opens the door by means of a lever 12. At the same time a switch 36 is closed by a spring, and when the door is fully open it closes a switch 32, so that current flows from 29 through relay 30, switch 32 and wire 33 to earth, closing the switch 34, so that current flows from 29 through the coil 28 of valve 25, switches 34, 36, 38 to earth, forming a holding circuit for 30. Pressure fluid is admitted by valve 25 to the cylinder 7, so that the door is closed, thereby opening 32, but 30 holds switch 34 until the door is closed, when latch 51 opens 36 and de-energizes 30 and 28. The switch 38 may be opened by a plate 39 on the outer face of the door or a handle 40 on the inside. In another form, the engine is energized to hold the door closed, the valve 25 being of the exhaust type, so that when its coil 28 is energized, the left end of the cylinder 7 is exhausted, and the pistons move to the left to open the door when the latch is released.

Title: Improvements in or relating to process for preparing crystals of monocalcium diglutamate
IPC: B64C13/14
Filed: 1954-05-20
Abstract: A process for preparing crystals of monocalcium diglutamate comprises preparing a solution containing monocalcium diglutamate, heating the solution to a temperature between about 60 DEG  C. and about the boiling point, at which temperature the solution is at least saturated, agitating the hot solution while seeding with solid phase monocalcium diglutamate, crystallizing monocalcium diglutamate from the seeded solution and separating the crystals. The first solution may be prepared by mixing glutamic acid, water and a basic inorganic oxygen-containing compound of calcium or by reacting glutamic acid in water with calcium hydroxyglutamate or monocalcium monoglutamate trihydrate.  The seeding material may be obtained by spray drying a solution of the salt, preferably after the removal of silicon and magnesium hydroxide and drying the spray dried material until anhydrous.  The solution to be seeded may contain, for example 50 to 70 per cent by weight of the salt.  The mono-calcium mono-glutamate trihydrate can be obtained by slurrying glutamic acid in water with calcium oxide or hydroxide until the pH is 10.6 to 10.8, usually at 50 DEG  to 60 DEG  C., separating insoluble matter and cooling to 20 DEG  to 30 DEG  C.  Calcium hydroxyglutamate is prepared by reacting equimolecular amounts of glutamic acid and calcium oxide or hydroxide in aqueous medium, the solution after filtering being concentrated at 80 DEG  to 90 DEG  C. to give a solution containing about 10 to 15 per cent by weight of the salt.  An example illustrates the process.
