Title: Process for controlling distillation column
Inventor: HIRAMATSU TERUAKI
IPC: B01D3/42
Filed: 1984-08-09
Abstract: A process is described for controlling a distillation column 1 in which a feedstock is distilled for separation into a product from the top of the column 1 having a first predetermined content SP1 of an intended component with a high boiling point and a product from the bottom of the column having a second predetermined content SP2 of an intended component with a low boiling point by controlling the flow rate of either one of the products and a part of the product from the top of the column is refluxed to the column 1. The process comprises the steps of computing a desired value Xs of the flow rate of the product from the bottom of the column 1 in accordance with a material balance and correcting this desired value Xs either in response to the larger of a first deviation  DELTA V1 of the content PV1 of the high boiling point component from its desired value SP1 and a second deviation  DELTA V2 of the content PV2 of the low boiling point component from its desired value SP2 when the control directions of the flow rate of said product by the polarities of the first and second deviations are the same; or in response to the second deviation  DELTA V2 when the control directions of the flow rate of said product by the polarities of the first and second deviations are different and controlling the reflux rate in response to a larger one of the first and second deviations; and controlling the flow rate of said one product accordingly. When the first or second corrected desired values do not fall in a given range the reflux rate is controlled in response to the limit values of the said range. <IMAGE>

Title: A/D converters
Inventor: DIEDERICHS ROLF
IPC: H03M1/00
Filed: 1984-10-08
Abstract: Analog signals, particularly those obtained from ultrasonic testing equipment, are converted into digital form by converters 800-804, and subsequently into logarithmic form by a coder 840, this arrangement being cheaper and having certain advantages compared with logarithmically- graduated converters. Converters 800-804, which are each of the simultaneous comparison type, are supplied by amplifiers 810-814 with signals within respective ranges that overlap. The upper ten stages of one 64-stage converter may for example be overlapped by the lower ten stages of the next converter. <IMAGE>

Title: Process for conditioning organic sludge
Inventor: OTT PETER
IPC: C02F11/128
Filed: 1984-11-08
Abstract: The process relates to the conditioning of organic sludges, for example, from effluent treatment, in order to improve the water extraction capability, to reduce the mass and the volume, and to prevent decomposition during further application. The conditioning is achieved with low energy input and without the use of chemicals. The sludge, containing at least 0.5 % organic dry substance, is excited constantly or at predetermined intervals, to a frequency of at least 0.3 s<-1>, while at the same time injecting oxygen. To induce oscillation/vibration, the use of rotating bodies or vibrators has been found particularly advantageous. As a result, the dry substance is reduced by more than 80 % at ambient temperature. The sludge volume reduces to less than 5 %.

Title: A drive system for a pump/compressor
Inventor: ROSTRON JOSEPH ANTHONY
IPC: F04C29/00
Filed: 1989-06-20
Abstract: A drive system for a pump/compressor which feeds a pneumatic circuit of a portable waste water sampling device, and comprising a plurality of individual electric motors (20) each operating at 12 volts and drawing a current no greater than 350mA at 2.5w, the motors driving a common pinion (23) with an output shaft (24) for connection to the pump/compressor. The use of a number of low capacity drive motors which together provide sufficient torque to drive the pump/compressor, avoids the danger of spark generation particularly in a potentially explosive environment such as may be found below ground. Since the motors are small they may be mounted conveniently within the sampling equipment, taking up no more space that would be occupied by a single motor of larger capacity.

Title: Heat storage units
Inventor: ELLIS GORDON
IPC: F24H7/04
Filed: 1990-05-16
Abstract: A heat storage unit comprises a heat store consisting of a stack of bricks, which are electrically heated by means of elements so as to take advantage of off-peak electricity. A secondary hot water heating circuit is heated by means of a primary circuit which includes a heat exchanger in contact with the store, in which water is super heated. The heat exchanger comprises chambers (17, 18, 19) consisting of opposed plates which are closely spaced together, since a large area is available for contact with the bricks lying between the plates and the force urging the bricks apart due to thermal expansion of the chambers is relatively weak. Depressions (20) in each plate abut corresponding depressions in an opposing plate. <IMAGE>
