Abstract: A variable speed rotor (7) forms with fixed components one or more displacement areas (11,12), to which inlet and outlet ports (20,33) are connected. The inlet ports are connected to a feed system and the outlet ones to a pressure chamber (35), connected to the feed system via a control valve (40), discharging a regulated quantity into a passage (19) in the system and a further one to an external outlet. The pressure drop of the flow to the external outlet is tapped off at a metering shutter and fed to both plunger faces. The metering shutter is formed in a working flow passage (38), extending radially from the valve. Together with system passage, into which the other flow is discharged, it is spaced in the axial direction of the plunger for a distance (c) less than the width (b) of an annular space (52) in the plunger formed between the first face (53) and a third one (56). The annular chamber is connected by a chamber (50) in the plunger to the pressure chamber (35).

Abstract: The improved mechanism for selecting the vertical positioning of load-bearing furniture components comprises a load-bearing column 10 placed between the work surface or seat 42 and the base 38. This load-bearing column has a double wall formed by two coaxial tubular bodies 14 and 12. A moving piston 32 placed in the cavity of this column divides the cavity into two chambers 16 and 18. A pressurised gas is distributed in the chambers. Valve components 68 are attached to the upper part of the said column and include a moving body 26, part of which has a reduced diameter and which is moved by a lever 22; these valve components allow the gas to be transferred from the upper chamber 18 to a small valve chamber 66. A pierced tube 62 connects up the said small valve chamber 66 with the lower chamber 16.

Abstract: The invention is directed to a food processing apparatus (2) having a lid (22) adapted to be placed on a vessel (10), with a cover member (26) of semi-circular cross section and having a passage (24) opening into the vessel (10) being provided on the lid. The cover member (26) is provided with a vertically extending rectangular receiving opening (32) for receiving a semi-cylindrical receptacle (34) adapted to swivel through 180 DEG  between a loading position and a discharge position. The receptacle (34) is adapted to receive whole fruits (45) without the operator contacting the shredding or cutting tools (12, 13), because the receiving opening (32) is closed in the loading position of the receptacle (34). Following loading of the fruits (45) into the receptacle (34), the latter is swivelled through 180 DEG , enabling the fruits to be discharged through the passage (24) into the vessel (10) where a cutter blade (12) is used, while in the use of a shredding or cutting disc (13) the fruits will come to lie on the disc for being processed following which they will drop into the lower part of the vessel (10). With the receptacle (34) in the discharge position, the processing tool (12) is not accessible from the outside either because in this position, too, the receptacle (34) maintains the receiving opening (32) closed.

Abstract: Apparatus and method for evaluating the likelihood of an event (such as a word) following a string of known events, based on event sequence counts derived from sparse sample data. Event sequences -- or m-grams -- include a key and a subsequent event. For each m-gram which was counted in the sample data, there is stored a discounted probability @ generated by applying a modified Turing's estimate, for example, to a count-based probability. For a key occurring in the sample data there is stored a normalization constant  alpha  which (a) adjusts the discounted probabilities for multiple counting, if any, and (b) includes a freed probability mass allocated to m-grams which do not occur in the sample data. To determine the likelihood of a selected event following a string of known events, a "backing off" scheme is employed in which successively shorter included keys (of known events) followed by the selected event (representing m-grams) are searched (302, 308) until an m-gram is found having a discounted probability stored therefor. The normalization constants (306, 312) of the longer searched keys -- for which the corresponding m-grams have no stored discounted probability -- are combined together with the found discounted probability to produce (304, 310, 314) the likelihood of the selected event being next.

Abstract: An image display is connected to the telephone network via a decoder, to which an input keyboard is connected for selective access to the text screen network by a selection signal. The keyboard also serves for input of information signals, contg. subscriber related data and selection data of a respective subscriber. The individual input information signals are stored in allocated memories, and an automatic selector provides the access to the text screen network. The selector is switchable by an external signal and, in its ON state, actuates the generation of the text screen selection signal, as well as the read-out of the memory contents for the decoder. The read-out is carried out in a preset sequence and in adjustable time intervals.
