IPC: A47C7/56
Filed: 1994-03-11
Abstract: A tip-up wall seat has a one-piece backrest (12) which has a planar rear side (14) and from the front side of which project bearing blocks (28) for providing a pivoted connection, between which bearing blocks the backrest (12) has an approximately horizontal stop face (30). The one-piece seat panel (32) is movable about the pivoted connection between a tipped-up rest position (R) and a pivoted-down sitting position, in which the seat panel (32) bears with a stop end (34) on the stop face (30) of the backrest (12). The stop face (30) extends from the front side to the rear side (14) of the backrest (12) approximately at the level of the pivoted connection and is an integral part of a peripheral, rear-side supporting edge (36) of the backrest (12), which delimits the lower end of the backrest (12) between the bearing blocks (28), which extend downwards beyond the stop face (30) over a length which approximately corresponds to the distance of the stop end (34) of the tipped-up seat panel (32) from the pivoted connection. This design of the tip-up wall seat prevents the accumulation of liquid residues on parts of the same. <IMAGE>

Title: Catalytic reaction of hydrocarbons with steam
IPC: C01B3/38
Filed: 1965-01-12
Abstract: The steam and hydrocarbon feed to be reacted over an active nickel catalyst at 550 DEG  to 850 DEG  F. (288 DEG  to 454 DEG  C.) to produce a hydrogenrich gas are first passed over a spent nickel catalyst which has been spent in the main reaction but retains residual activity, e.g. it may retain 20 to 50% of the original active nickel surface area.  The spent catalyst acts to remove sulphur and coke-forming materials and produces some hydrogen for mixing with the unreacted steam and feed.  The reaction over the spent catalyst is carried out at lower temperatures, e.g. 400 DEG  to 700 DEG  F.  (204 DEG  to 371 DEG  C.) than the main reaction.  The active catalyst is preferably of the co-precipitated type and comprises 40 to 60% by weight nickel with the rest alumina or silica, a promoter metal being added.  The feed may be liquid, e.g. C5 to C8 paraffins, or gaseous (e.g. natural gas) or a mixture thereof.  Two apparatus are described in which the spent and active catalyst are in the same vessel (see Figs. 1 and 2, not shown), and a flow diagram is provided which illustrates the use of separate vessels, each vessel acting in turn as the main and the initial catalyst vessel (see Fig. 3, not shown). Oxidation of the spent catalyst may be avoided by gas blanketing, e.g. with N2, N2 and CO2, H2, or inert hydrocarbon. Two specific examples are described in which H2-rich gases are produced at low conversions (i.e. up to 40% conversion of hydrocarbon) and CH4-rich gases at higher conversions, the degree of conversion depending on the space velocity, which may be controlled.

Title: Procedure and apparatus for starting an oxidation process
IPC: C02F11/08
Filed: 1956-01-16
Abstract: 785,267. Treating sewage or waste effluents. STIRLING DRUG, Inc. Jan. 16, 1956 [Jan. 18, 1955], No. 1440/56. Class 111. [Also in Group XIII] The invention consists in a process and apparatus for starting the eventually-selfsustaining oxidation process disclosed in Specification 706,686 (referred to). Valves B and A are first opened, admitting steam to a heat exchanger 3 and to the reactor R in which the oxidation process is to take place. Steam from the reactor passes to a separator S 1  whence the vapour passes to a heat exchanger 2 while the condensate passes to a heat exchanger 1. Steam from exchanger 3 is vented, while that from exchanger 2 passes through a separator S 2 , a. back pressure valve and (optionally) an expander, turbine, turbo-generator or the like, and that from exchanger 1 through a valve C and a cooler or power equipment. When the apparatus has been heated to a temperature above 280‹F., valve A is closed and an aqueous dispersion of combustible material such as spent pulping effluent, sewage or finely-comminuted garbage is withdrawn from storage through a valve E by a pump and discharged through the exchangers 1, 2 and 3 into the reactor R. Compressed air is admitted to the liquid between exchangers 1 and 2. Some oxidation begins in the reactor R, the temperature of the liquor/air mixture being further raised by the exothermic nature of the reaction. The condensate from separator Si is now reacting liquor ; valves C and E are closed and valve D is opened so that the liquor, in which the pressure is rising to the autogenetic pressure, is re-cycled. When the temperature of the mixture of liquor and air exceeds 280‹F., the oxidation is proceeding at a rate which will sustain the process and the starting steam is no longer required, whereupon valve B is closed. Valve D is closed to terminate re-cycling and valves E and C are opened to permit liquor to pass continuously through the system. The effluent passing through valve C is now oxidised liquor, and the ash comprising inorganic residue is in soluble or slurry form therein. In its simplest form, Fig. 1 (not shown), the invention comprises the reactor R, exchanger 3, the starting steam supply to both, and means for re-cycling reactor effluent. A mixture of liquor and air is normally supplied through the exchanger.

Abstract: 523,847. Automatic control systems; refrigerating systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 16, 1939, No. 1471. Convention date, Jan. 15, 1938. [Class 38 (iv)] [Also in Group XIII] Temperature ; humidity ; fluid pressure.-An air conditioning system comprises a reversible cycle refrigerating machine in which a heat exchanger 19 which may serve as evaporator or condenser is positioned together with a humidifier 47 in a duct containing a fan 15 and filter 18. A room thermostat 55 upon a demand for heat energizes a relay 61 and when the desired temperature has been reached or upon a demand for cooling short circuits that relay. Switches 59, 90 respectively must be closed to effect heating or cooling respectively. In the former case a relay 64 is energized to actuate a time relay 65 which starts the compressor motor 21 and solenoid valves 26, 27 are opened so that refrigerant is pumped through valve 27 into heat exchanger 19, check valves 33, check valves 39. scale trap 40, heat exchanger 22 and valve 26. The flow is controlled by a thermostatic valve 41 according to the temperature of the fluid issuing from the heat exchanger 22 wherein heat is supplied from well or other water from a supply pipe 75. Economical use of this water is obtained by a low control valve 70 adjusted by a reversible shaded pole motor 79 the shading windings of which are selectively controlled by a switch 71 responsive to the pressure of the fluid leaving the heat exchanger 28. A humidostat 68 operates a solenoid valve 49 when the relative humidity in the room is insufficient and water passes over heating coils 51 to the humidifier. When the switch 90 is closed the plant operates to cool the air passing through the duct until the thermostat 55 closes the circuit of the relay 61. Solenoid valves 24, 25 and 38 are opened instead of valve 26, 27 and a relay 91 is energized to start the refrigerator motor by operating relay 65 and to energize solenoid 72a and de-energize solenoid 73a, whereby the direction of flow of the water passing over the heat exchanger 22 is changed. The refrigerant is now pumped through valve 24, the heat exchanger 22, valve 38, liquid receiver 23, duct valve 34, scale trap 44, heat exchanger 19 and valve 25. The flow is controlled by thermostatic valve 45 in accordance with temperature of the fluid leaving the heat exchanger 19. The pressure of the fluid leaving the compressor controls the flow of water passing over the heat exchanger 22 by operating a valve 95. Excessive fall in pressure of the refrigerant entering the compressor actuates a switch 97 to stop the plant. Undue fall in temperature in the casing 28 is prevented by a thermostatic switch 58 which disconnects the electric power supply:
