Abstract: A paper feeder for a printer in which a paper separator roller 15 is rotatably provided in the end portion of a paper holder 12 so that when a paper feed roller 14 is rotated in the paper feed direction, the paper separator roller 15 is arranged to stop at a predetermined position and act similarly to a conventional friction pad, while when the paper feed roller 14 is rotated in the paper return direction, the paper separator roller 15 also rotates in synchronization with the above rotation. By way of vibrating the paper separator roller 15 in the rotational direction or another direction, paper sheets P stacked on the paper holder 12 are vibrated for the purpose of being successively moved in the portion at which the two rollers 14 and 15 are positioned in contact with each other. As a result of this structure, the paper feeder of the printer according to the present invention can be prevented from local abrasion of the paper separator roller 15 causing papers to be fed in an overlap manner, and stop of paper feed can be prevented, and papers can be assuredly fed one at a time to the printing mechanism portion 1.

Abstract: The present invention relates to methods and apparatus for controlling a process for the separation of air to obtain oxygen, argon, and nitrogen products, and more particularly for controlling the composition of the feedstream to a column (34) for producing crude argon. The nitrogen content of the feedstream (46) is directly analyzed in real time and maintained within a preselected range. The results of the analysis is used to control the operation of the process, for example, by adjusting the reflux or product withdrawal rates. Argon production is thereby maximized without risking a dumping phenomenon in the crude argon column.

Abstract: The invention concerns o-ordinate reading apparatus for feeding co-ordinate data to a computer. Such apparatus comprises a tablet (21) defining a co-­ordinate surface, a co-ordinate designator (11) movable across the tablet and electro-magnetically coupled to it, and position signal producing means coupled to the tablet and co-ordinate designator. Co-ordinate calculating means (31), fed by the position signal producing means, calculate co-ordinate value of the point designated by the co-ordinate designator. A pulse sequence generator (7) converts the calculated value into two pulse trains in quadrature, for feeding to the computer. When this apparatus is operated in an absolute co-ordinate mode, different origins on the display and the tablet may result in part of the display being unused, and movement of the co-ordinate outside the area corresponding to the display may cause the origin on the display to move. Initialization means are therefore provided, consisting of initialisation control means (61) for detecting a designation operation, and initialisation circuitry (7) for generating an initialising pulse sequence of two pulse trains in quadrature. Both pulse sequences are sent to the computer.

Title: Method and apparatus for sterilizing fluids
Inventor: WEDEKAMP HORST
IPC: C02F1/32
Filed: 1988-11-04
Abstract: UV sterilising devices are employed to sterilise liquids and/or gases by means of UV radiation. The effective use for sterilisation of media with varying or relatively high temperature, particularly of hot water, fails because the emission spectrum of the low pressure mercury vapour lamps is directly dependent on the operating temperature and also on the ambient temperature. Variations in the operating temperature lead, on the one hand, to a diminution of the sterilising radiation and, on the other, to the triggering of intracellular repair mechanisms. The invention provides that the vapour pressure of the mercury in the lamps used remains substantially constant with changes of the wall temperature of the lamps. In this way, the UV emission spectrum of the low pressure mercury vapour lamps is kept substantially stabilised even with varying operating temperatures so that, for the first time, the bactericidal UV performance (emission of line 254 nm) can be kept almost constant over a wide band of variation in operating temperature. At the same time, the increase in the UV-A emission in which accompanies rising temperature in conventional low pressure lamps and which activates the cellular repair mechanisms, is prevented from taking place. <IMAGE>

Abstract: A front transaxle for an all-wheel drive motor vehicle wherein the housing (12, 12a, 12b) of an interaxle differential (13) is operatively connected to a shiftable transmission and, via a tubular shaft (17), drives one bevel gear (19) of an angle drive (18). The other angle drive bevel gear (20) is operatively connected to a longitudinal propeller shaft (21) for driving the rear axle. One front wheel drive shaft (15) extends from the interaxle differential through the tubular shaft. The housing (22, 22a, 22b) of the angle drive is connected by a flanged joint (24) to the transmission outer housing (23). The arrangement permits the differential and angle drive subassemblies to be manufactured and tested at different locations while preventing the mixing of lubricants between the two subassemblies upon their assembly into the transaxle.

The stripping knife (13) is preferably held by at least two guide bars (28), which in each case bear at least one guide roller (17). The control of the stripping knife (13) includes a shaft (25) with cam disc (30) fastened thereupon, into which disc a guide groove (14) is milled. The roller (17) engages in the groove (14). The bounding edges of the guide groove represent a projection of the rotor cross-section and the shaft (25) of the control rotates synchronously with the rotor. <IMAGE>

Abstract: For micromovement of an object relative to a predetermined processing or analysing position, a micromanipulator is disclosed which can be employed, for example, for executing object movements in scanning tunnel microscopes (RTM). The micromanipulator has a plurality of movement elements (2, 2', 2"), which both support and move the object (1). For executing micromovements, the movement elements can be adjusted piezoelectrically, and the supports (3, 3', 3") can be displaced by the deformation of piezoelectric material. In order to be able to execute micromovements with the micromanipulator too, micromovements can be carried out with at least one of the movement elements (2). The support (3) of the movement element (2) itself is suitable for this. The support (3) can be inserted in a piezoelectrically deformable sleeve (7). However, it is also possible to design a partial section (14) of the baseplate (5a) to be macromovable, on which the movement elements (2a, 2a', 2") are fastened. <IMAGE>

Abstract: This invention relates to a process for the separation of acrylonitrile used in the cyanoethylation of glycols to produce a bis(cyanoethylated) aliphatic glycol from the resulting glycol which is then reduced with hydrogen to produce the corresponding bis(aminopropyl) aliphatic glycol. In this process, acrylonitrile is reacted with an aliphatic glycol in stoichiometric excess and the acrylonitrile removed from the cyanoethylated glycol by reaction with aliphatic primary or secondary amine prior to effecting the hydrogenation of the cyanoethylated aliphatic glycol in the presence of the acrylonitrlle-amine reaction product. The reaction product then can be separated by conventional techniques such as distillation.

Abstract: A spread spectrum communications system includes an encoder for differentially encoding a spread spectrum spreading code sequence in accordance with an input data signal. Each chip of the spreading code sequence is inverted, or not inverted, relative to the polarity of a corresponding chip of the spreading code sequence a fixed time delay previously, depending on whether the input data is a logic one or zero, respectively. At the receiver, the data is recovered in a differential data decoder wherein the presently received chip of the spread spectrum signal and a previously received chip of spread spectrum signal, a fixed time delay previously, are compared one chip at a time. Since it is the spreading code sequence that is differentially encoded and differentially decoded, there is no need for a synchronized code sequence generator at the receiver, and data synchronization is achieved after one cycle time of the received spread spectrum spreading code sequence has elapsed.
