Title: Regenerating adsorbent material
IPC: B01J20/12
Filed: 1945-12-21
Abstract: <PICT:0620397/III/1> Adsorbent materials used in the treatment of gases and forming a bed in an adsorbing tower are reactivated by passing a heated gas through the bed, imparting a preheat to the gas prior to its introduction into the bed by first passing it over low pressure steam coils, and then boosting the temperature of the gas by electric heating means of the radiant type, until the gas reaches a temperature above the volatilization temperature of materials adsorbed in the bed of adsorbent materials, heating the bed during the passage of gas therethrough by heat applied to the bed interiorly thereof in addition to the heat imparted by the gas passing therethrough, and continuing heating the bed until the bed reaches a temperature in excess of the volatilization temperature of the materials adsorbed in the bed, but below the ignition temperature of any adsorbed materials in the bed.  An apparatus for effecting the process comprises two adsorbing columns, column A being used for adsorbing the moisture content of gases and column B being regenerated.  The gas for regeneration is forced by a blower 19 past a steam heated coil 25 and a radiant electric heater 53 through a valve 23 into the bottom of the column B.  The columns A and B contain adsorbent material 14 in which are embedded a steam heated coil 13 provided with radiating fins 13a and electric heating units 49.  These heating means may be used separately or in combination. After regeneration has been completed, cooling of the columns may be accelerated by replacing steam in the coil 13 by a cooling media from a cooler 34.

Title: Improvements in haemostatic catheter
IPC: A61F2/958
Filed: 1957-11-08
Abstract: 846,779. Catheters. ODDO, V. J. Nov. 8, 1957, No. 34912/57. Class 81(2). A haemostatic catheter for use following prostatectomy comprises a drainage tube 10 which carries a pair of inflatable torus-shaped balloons 14 15 held together by a common integral wall 16 or a connecting membrane, so that when inflated they can exert pressure on the vesical neck as well as on the prostate bed. The catheter comprises a tube 10 having a closed distal end 12 adjacent which are openings 13 communicating with a central drainage channel 11. Balloons 14, 15 having a common wall 16 are disposed near the distal end 12 of the catheter, the balloons 14, 15 being inflatable through a single duct 17 formed or embedded in the wall of the tube 10. In use the balloon 15 nearest the distal end 12 is located in the bladder and presses against one side of the vesical neck, the second balloon 14 presses against the other side of the vesical neck and the common wall 16 presses against the vesical neck so that bleeding following prostatectomy is checked. In a modification the two balloons communicate with one another, the wall portion joining them being more resistant to inflation than the balloons themselves. Each balloon may be separate from the other and be inflated through a separate inflating duct, the walls of the balloons being interconnected by a flexible elastic membrane which presses against the vesical neck when the balloons are inflated. The space between the balloons enclosed by the membrane may be independently inflated through a third inflating duct.

Title: Improvements in hydroforming
IPC: C10G35/14
Filed: 1955-12-06
Abstract: In the hydroforming of naphthas at low pressures in the presence of a platinum group catalyst using a fluidized process, the spent catalyst is treated firstly in a regeneration zone with an oxygen containing gas, then with a substantially dry and sulphur-free hydrogen containing gas, and is subsequently treated in a stripping zone with the gaseous products formed in the hydroforming zone in a stripping zone and is finally returned to the reaction zone substantially free from carbon, sulphur, and oxygen-containing material.  In a preferred embodiment, the spent catalyst is first stripped with nitrogen prior to regeneration, and the purified hydrogen is obtained by fractionating the hydroforming products, scrubbing the gas in an aqueous alkaline solution of ethanolamine, and drying over alumina. The regenerated and stripped catalyst may also be treated with chlorine before return to the reactor.ALSO:In the hydroforming of naphthas at low pressures in the presence of a platinum group catalyst using a fluidized process, the spent catalyst is treated firstly in a regeneration zone with an oxygen containing gas, then with a substantially dry and sulphur-free hydrogen containing gas, and is subsequently treated in a stripping zone with the gaseous products formed in the hydroforming zone in a stripping zone and is finally returned to the reaction zone substantially free from carbon, sulphur and oxygencontaining material.

Title: Data transmission system
IPC: H04L25/52
Filed: 1974-08-08
Abstract: 1479774 Buffer store SIEMENS AG 8 Aug 1974 [26 Sept 1973] 35056/74 Heading G4C [Also in Division H4] A buffer store P is provided between a data terminal DEE transmitting data intermittently on line SDE, and a transmitting unit DUE which transmits data under control of a timing pulse train, each data bit from the terminal being read into a buffer stage identified by a write marker SM which is moved in response to receipt of data bits, and the contents of the buffer stage identified by read marker LM which is moved in response to the timing pulse train being read to the transmitting unit. The two markers, which may be ring counters marking successive ones of n lines, are advanced cyclically and arrangements are provided to prevent one marker overtaking the other. The buffer may be of a length sufficient to store a single multi-bit character including start and stop elements. If a single character is buffered the write marker SM is stopped after buffering of the stop element, i.e. the write marker now points to the start element. Read out from the buffer is then started and the read marker LM reads out successive stages until the stop element in stage KN is read out. The marker is then halted and, in the absence of further data from the terminal, the stop element will be read out repetitively, i.e. the pause between characters is lengthened. The read marker is held until a predetermined quantity of data is received from the terminal, e.g. until the write marker points to stage K3, the predetermined quantity being chosen to prevent the read marker overtaking the write marker given the most unfavourable speed difference. In the terminal is transmitting data faster than the transmitting unit can receive them the pauses between characters received from the terminal are used to continue transmission which thus occurs with shortened pauses between characters. The length of the buffer is chosen such that even with the largest possible difference between transmission rates the buffer can hold sufficient data to allow the randomly occurring pauses between characters to be lengthened or shortened to prevent one marker overtaking the other.
