Abstract: 57 The invention relates to a new process for producing titanium IV and zirconium IV pyrophosphates, certain of which are new compounds, and their uses. The pyrophosphates are prepared by reacting a metal tetraester with phosphorus pentachloride, with or without the addition of an hydroxyl compound, such as an alcohol or a phenol. Depending on the molar ratio of the components, the compounds produced may contain cyclic or straight chain pyrophosphate groups and alkoxy groups attached to the metallic ion. In addition to forming new compounds, the process of the invention produces the desired products without difficult-to-separate by-products. The products of the invention are useful as flame-retardants, antioxidants, coupling agent, impact modifiers and processing aids, and the reaction for their preparation may be represented as follows:wherein M is titanium or zirconium; R is a monovalent hydrocarbon group optionally substituted with halogen or oxygen substituents; n is an integer from 1 to 4; m is an integer from 0 to 4; x is an integer from 0 to 2; q is an integer from 0 to 4; n is greater than or equal to m; n = p + m + q; x + m + 2p + q <sub>=</sub> 4; and when x is greater than 0, q is 0.

Abstract: 2.1 In the case of an apparatus for the reproduction of data, which can be read by means of an optical scanning device from the data tracks of a recording medium by it being possible to guide a light beam on the data tracks by means of a track control circuit, during track jumping the optical scanning device is moved to the desired data track by a jump pulse (SI) and stopped there by a brake pulse. Because the brake pulse is always the same, major deviations from the desired track are possible, requiring subsequent correction. 
<??>2.2 In order to adapt the brake pulse to the respective jumping conditions, when jumping from one track to the next an over-small first brake pulse (B1) is emitted and the time (T) taken to reach a predeterminable point (P) of the next data track is measured. The measured time (T) is taken to determine the amplitude and/or duration of a second brake pulse (B2), which stops the optical scanning device approximately in the middle (M2) of the data track. In the case of a second solution, a test jump is carried out with a subsequent test brake pulse. The transient response of the track error signal is taken to determine the amplitude and/or duration of the brake pulse required for subsequent jumps and is stored.

Abstract: An electrolytic process for the production of an aqueous sodium hydroxide solution uses an oxygen reduction cathode and a cation exchange membrane. The electrolytic cell comprises a cation exchange membrane dividing it into anodic and cathodic compartments. The cathode is placed directly against the membrane and the compartment is supplied with a moist gas containing O2. To obtain a weight concentration between the cation exchange membrane and the cathode of less than 38.8% of NaOH (a higher concentration reduces the life of the membrane), aqueous solutions of NaCl (anolyte) with a weight concentration of NaCl less than 200 g/l are electrolyzed. The O2-containing gas contains water vapor.

Abstract: The device for detecting labels (21) which serve to protect goods (20) against theft and which are provided with an electric resonant circuit with a resonant frequency in the MHz range comprises a plurality of pairs of transmitting and receiving antennas (8-13) which in each case delimit passages (5-7) which are to be kept under surveillance. Electromagnetic waves whose frequency is swept in sweep cycles beyond the pre-defined resonant frequency of the labels are in each case radiated by the transmitting antennas (8, 10, 12) of the pairs. The sweep cycles of all pairs are synchronised with one another. A receiving circuit (17-19) which detects the presence of a label is connected to the receiving antenna (9, 11, 13) of each pair. To simplify installation, it is proposed according to the invention that the RF oscillations radiated via the transmitting antennas as electromagnetic waves are generated by decentralised RF generators (14-16) in each case individually assigned to the transmitting antennas and that the sweep cycles are synchronised with one another using a synchronisation signal with at least one frequency in the LW range which is generated in a central unit (22) and fed to the RF generators. <IMAGE>

The resulting quantization error vector y is dimensionally divided by a second vector quantization unit 510. The resulting weighted vector quantized shape index data are outputted at output terminals 5121, 5122. The quantized values Y1' and Y2' are dimensionally combined and added by an adder 513 to the quantized value X0'. The resulting quantized value X1 is outputted. <IMAGE>

Abstract: A reactive distillation process is described, making it possible, in the same vessel, to carry out a catalytic reaction and to isolate the required product by distillation, in which the liquid phase containing the reactants passes from the top downwards through at least one catalyst bed without the vapour phase of the distillation passing through the said catalyst beds. These operating characteristics are in practice obtained in a reactive distillation zone (C) which comprises an alternation of distillation cells (D) comprising one or a number of trays (5) and of reaction cells (R) containing the catalyst beds and designed so that the liquid phase flowing off a distillation tray (5) flows over a spillway (7) via a down column (6) to reach the catalyst bed (8) at its bottom and to pass through it as an upward stream before pouring by overspill onto a distillation tray (5) of the following distillation cell (D), so that the distillation vapour which travels from the bottom upwards through the distillation trays (5) does not pass through the said reaction cells (R). Each reaction cell (R) is physically separated from the adjacent distillation cell(s) (D). The process and the apparatus which are described can be applied particularly to the reactions of synthesis of tertiary alkyl ethers by addition of aliphatic monoalcohols (methanol, ethanol) to isoolefins (isobutene, isopentene). <IMAGE>

Abstract: The present invention relates to an automatic sheet feeding device of a printer. A pickup roller (1) picks up a record sheet from a sheet feeding plate in response to forward rotation of a driving gear (2). A first rotation member (5), during forward rotation of the driving gear, normally rotates with the pickup roller, and includes a first circumferential formation (6). A stopping member (12) is adapted to engage the first circumferential formation to arrest its forward rotation. A second rotation member (7), during forward rotation of the driving gear, normally rotates with the pickup roller, and includes a second circumferential formation (8). Continued forward rotation of the pickup roller and the second rotation member once the forward rotation of the first rotation member has been arrested by the stopping member causes the second circumferential formation to release the stopping member from the first circumferential formation, thus allowing the first and second rotation members and the pickup roller to continue their rotation in the forward direction. A mechanism is provided to prevent the pickup roller from rotating in reverse when the driving gear is rotated in reverse. <IMAGE>
