Abstract: It is known to produce rutile titanium dioxide by oxidising TiCl 4  in the presence of AlCl 3  and PCl 3 . The AlCl 3 , used normally in an amount such as to provide from 2 % to 4 % by weight Al 2 O 3  in the product, is essential in order to produce the rutile structure but is of disadvantage in that it leads to corrosion of metallic reactor surfaces. The invention reduces the amount of AlCl 3  necessary to provide the rutile structure, and thereby enables this disadvantage to be minimized, by introducing the PCl 3  after the AlCl 3  and when the TiCl 4  conversion has reached 80% by weight or more.

Abstract: A signal encoder and classifier particularly adapted to speech recognition includes a circularly addressed buffer (26, 104) which is independently addressed by a new data writing address system (112, 102, 114, 118, 128, 130, 132, 134, 142) and a buffered data reading system (150, 152, 154, 156, 158, 160, 162, 164, 166) so that writing and reading of data may be accomplished on a time shared basis. This time shared operation permits serial writing and reading of the pattern data 112 without interrupting income signal storage. The writing data address system addresses the data into the buffer in a circular fashion while the reading data address system utilizes stored addresses (122, 124, 136, 138, 140) identifying the beginning and end of the signal patterns for addressing sequential patterns from the buffer.

Abstract: A transmission for an automotive vehicle, including a manually controlled main transmission and an automatically controlled subtransmission. The main transmission includes a main casing within which are rotatably supported a tubular intermediate shaft and a power output shaft, in parallel. Several gear wheels on each of these shafts cooperate, and by their selective engagement various different speed driving ratios may be obtained between the shafts. One end of the intermediate shaft and one end of the power output shaft project from one end of the main casing. A power input shaft passes coaxially through the tubular intermediate shaft and is rotatably supported therein. The ends of the power input shaft project from the ends of the tubular intermediate shaft. The subtransmission includes a subcasing attached to the aforesaid one end of the main casing, and within the subcasing a planetary gear mechanism is arranged between the power input shaft and the tubular intermediate shaft so as, under the control of a fluid pressure actuator, either to couple these two shafts together directly, or to provide an increase of rotational speed from the input shaftto the intermediate shaft. A fluid pressure control device selectively supplies actuating fluid pressure to the actuator, and is located within the subcasing in a position axially opposing the end of the power output shaft. The end of the power input shaft remote from the subcasing is driven. The fluid pressure control device is automatically controlled according to operational parameters of the vehicle to selectively supply fluid pressure to the actuator.

Abstract: The invention relates to a process for dewatering extracted sugarbeet chips which are first subjected to preliminary pressing, in which a first press water fraction is separated off, after which a liquid (auxiliary) which promotes dewatering is added and the sugarbeet chips mixed with the added auxiliary are then mixed, kneaded and relayered without pressing out water, and the sugarbeet chips then pass through at least one further press zone in which at least a second press water fraction (30) is separated off. The novel feature is the fact that at least part of the second press water fraction (30) is added again to the sugarbeet chips after the latter have been pressed. The invention furthermore relates to a beet chip press for carrying out the abovementioned process. The novel feature here is primarily the fact that the collecting and conveying means (16,17) for the pressed pulps as well as the second press water fraction (29) are arranged below the second, horizontal press spindle (13), and that, in the first zone of the collecting and conveying means, an outlet sieve (18) is provided for part of the second press water fraction (30), a conveying pipe (19) being connected to said sieve downstream of the latter and said pipe being connected to the beet chip channel between the preliminary and subsequent press zones (B,C,D). <IMAGE>
