IPC: C10L5/44
Filed: 1989-07-28
Granted: 1993-03-03
Abstract: A process and apparatus for generating steam from wet fuel, wherein water is evaporated from the wet fuel by bringing the fuel into direct contact with superheated steam. The steam is superheated by bringing it into contact with a hot heat carrier. The heat carrier is heated by bringing it into direct contact with flue gas produced by burning the dried fuel and the heat carrier is used to superheat the steam.

Abstract: In a firing and drying furnace with fuel gas generators for ceramic mouldings and green bricks, a firing and drying furnace in the form of a tunnel is provided to heat them while facilitating economical gas generation and, in order for the exhaust gases from combustion to meet the statutory purity standards, a secondary air feed pipe is inserted in each feed line (5) carrying producer-gas freed of all residues produced in a gas generator to exhaust gas burners. The suitable producer-gas is fed manually or mechanically with the aid of sensors which respond to the change in the furnace temperature and adjust the quantity of producer-gas supplied. The producer-gas is preferably fed in at low pressure in a regulating region with waste gas burners (3, 4) and controlled by the furnace temperature as described above.

Abstract: The device described is intended to permit the determination of the mobility parameters of a lift. The lift has a cable which passes over a drive wheel. At one end of the cable is the cage, at the other end the counterweight. The drive wheel is driven by a motor controlled by means of a control circuit. The drive wheel is linked to a brake device which can be operated by means of the control circuit. The device also includes a data-processing unit with a timer. Connected to the input of the data-processing unit is at least one distance-of-travel sensor. The data-processing unit has further inputs, connected to switch points of the control circuit, the signals controlling the motion of the lift being applied to these switch points. In the process, used to check the adherence of the cable to the drive wheel, the lift is intentionally accelerated or decelerated. The mobility parameters of the cable and drive wheel are determined separately, enabling conclusions to be drawn as to the ability of the wheel to drive the lift.

Date Jun. 28, 1990.Titaniferous solid containing titanium (IV) oxide, for example ilmenite, is reacted with silicon tetrafluoride gas at 800 DEG  C. or more and at a pressure of at least 1 atmosphere to produce titanium tetrafluoride vapor and silica. The vapor is rapidly removed from the reaction zone, preferably by rapid cooling to solid titanium tetrafluoride, at a sufficient distance from the reaction zone so as not to quench the reaction. The titanium tetrafluoride may be hydrolysed to produce titanium dioxide and hydrogen fluoride which is combined with silica to regenerate silicon tetrafluoride. It is preferred to pretreat the titaniferous solid by grinding and then roasting at 700 DEG  C. to 750 DEG  C. in air. Products of the reaction may be separated and purified by condensation and resublimation.

Abstract: The shuttle valve (10) has a valve member (30) which includes first (32) and second (36) diameter sections disposed within small diameter (22), reduced diameter (24), and enlarged diameter (26) bore sections of a stepped bore (14) located in a valve body (12). The small diameter bore section (22) communicates with a brake feedback line connection (20), the reduced diameter bore section (24) communicates with an outlet opening (40), and the enlarged diameter bore section (26) communicates with an inlet opening (50). The second diameter sections (36), of the valve member (30) includes a transverse opening (44) which communicates with a longitudinal orifice opening (46) that leads to a chamber (48) located at an end of the valve member (30). Seals (60, 70) are disposed about the first and second diameter section (32, 36) and the valve member (30) biased by a spring (80) toward an at-rest position. Located about the first diameter section (32) of the valve member (30) is a freely movable orifice member (90) which includes a radial orifice opening (94) at one surface thereof. The sudden communication of high fluid pressure through the inlet opening (50) results in a slightly delayed displacement of the valve member (30) and movable orifice member (90), and the displacement of the valve member (30) and movable orifice member (90) then causing fluid to be communicated through the movable orifice opening (94) so that fluid communication with the outlet opening (40) is restricted.

Abstract: For transmitting data provided by track devices (G1) to passing vehicles, line conductors (L) of limited extent are connected to the track devices. The track devices are cyclically activated by a control station (LST). During this process, the control station transmits, for example, call-up messages for forwarding to the associated line conductor to the respective track device via a data line (K1). If these messages are received and acknowledged by a vehicle, this is detected by the control station which, by connecting a control code (+U) to the data line, causes the track device to output the data provided by the track device. The transmission process is ended by a second acknowledgement message. If the control station sends a continuous signal outside the times needed for calling up the vehicles and possibly the reception of acknowledgements, the vehicles can carry out a self-locating process in this time via the line conductors over which they run. The special advantage of the device according to the invention is that track devices of very simple construction can be used. <IMAGE>

Abstract: A system for validating coins comprises a transmitter coil (2) for transmitting low-frequency electromagnetic radiation through a coin (1) to be validated and a receiver coil (3) for receiving radiation having passed through the coin. An inverting amplifier (4) is provided in a feedback path between the receiver coil (3) and the transmitter coil (2) thereby providing a 180° phase shift. Thus, for the unique frequency which causes a 180° phase shift within the coin, there is provided positive feedback, and a resonance condition occurs at that frequency. By measuring the frequency of this resonance and comparing it with a reference value, the coin can be validated.
