Title: Taking off fibre flocks from bales of textile fibres, e.g. cotton or chemical fibres
Inventor: TEMBURG JOSEF
IPC: D01G7/04
Filed: 1990-11-02
Abstract: In a method for stripping fibre flocks from bales (1) of textile fibres, (e.g. cotton, chemical fibres) by cutting from the top of the bales, a stripping member is moved backwards and forwards over the bales and lowered before a pass, the teeth of a cutting roller (8) pointing in one direction and cutting into the bale surface through grid bars (7). In order to provide greater production that is comparable in terms of quantity in both travel directions, after being lowered the stripping member (8) makes one pass in the forward direction and then at least one pass in the reverse and/or in the forward direction without being lowered. In accordance with a further solution to the problem the distance between roller (8) and grid (7) is adjusted in a vertical direction. Vertical displacement of take-off member 5 carrying roller 8 is effected by lifting motor 11 while longitudinal travel of carriage carrying member 5 is effected by motor 12. The motors 11 and 12 are connected via control lines 14 to a control device 13 (e.g. microcomputer with microprocessor) connected to a memory 15. <IMAGE>

Title: Digital audio tape recording apparatus
Inventor: OKADA TSUYOSHI
IPC: G11B20/18
Filed: 1991-06-10
Abstract: Apparatus for compressing and expanding digital data in LP (Long Play) mode recording and reproducing with a digital audio tape recorder, and for encoding level data, which has sufficient resolution especially near O decibels. The apparatus comprises a first shift register (21) to which incoming parallel data is supplied and which transforms the parallel data to serial with the MSB (Most Significant Bit) of loaded parallel data being retained in the register while shifting the parallel data toward the LSB (Least Significant Bit) direction. The load signal LD of the first shift register (21) is generated by a load signal generator means which comprises a first binary counter which generates the load signal by employing a mode signal and by comparing the output of the first binary counter with input parallel data to be loaded. The output of the first shift register (21) to which signal processing has been provided (20) is input to a second shift register (11) which transforms the serial data to parallel. A second load signal generator means (65) derives load signals G1 to G4 to retain a partial output of the second shift register (11) and the output of a second binary counter (19) according to the output of the second shift register (11) and the mode signal. <IMAGE>

Title: Digital sound source device and external memory cartridge used therefor
Inventor: NAKAGAWA KATSUYA
IPC: A63F13/54
Filed: 1991-09-26
Abstract: A digital sound source device which includes a semiconductor memory coupled to a central processing unit, the memory having a quantized data storage area and a program data storage area. A series of quantized data sequences and stop codes are stored in a series of locations in the quantized data storage area, and a start address is set in a particular location in the program data storage area. When the start address is read out from the program data storage area, the quantized data are successively read out from the quantized data storage area and are successively loaded in the data register. When the stop code is read out from the quantized data storage area, a read/write control circuit inhibits the loading of data into the data register. The quantized data loaded onto the data register are converted into analog voice signals by a D/A converter circuit.

Title: Piston and cylinder arrangement with reversing valve disposed in the piston.
Inventor: ROBINSON MICHAEL
IPC: F01L21/04
Filed: 1991-12-05
Abstract: Fluid under pressure supplied to a hollow chamber (5) in a piston head (4) is fed successively to opposite cylinder spaces (13, 14) having bleed holes (11, 12). The piston head (4) is provided with a first bore providing communication between the chamber (5) and the first space (13) and a second bore providing communication between the chamber (5) and the second space (14), the first and second bores having valve seats (15, 16) on their end regions facing the chamber and being larger than the bleed holes (11, 12). A resiliently flexible valve member (18) co-operates with the first and second valve seats (15, 16) so as successively to block off the first and second bores respectively. An elongate element (21) carries the valve member (18) and has first and second end regions (22, 23) projecting through the opposing faces of the piston head (4) into the first and second spaces (13, 14). In use, fluid supplied to the chamber (5) is switched from one space to the other when the elongate member (21) is struck by a respective cylinder end (8, 9). The resilience of the valve member allows it to store some energy so that when triggered, it can move independently of the initial switching force on the "load and fire" principle. <IMAGE>

Title: Conductive polymeric composite
Inventor: RHEE SUH BONG
IPC: C08L65/00
Filed: 1993-05-27
Abstract: A conductive polymeric composite with an improved electrical activation density obtained by compounding a ferrocene derivative used as a dopant with a polypyrrole. The conductive composite can be produced by use of a chemical method or an electrochemical method. In the case of using the chemical method, pyrrole or its derivative is dissolved in a solution containing a ferrocene derivative, together with one or mixture of ferric trichloride, ammonium persulfate and copper chloride-aluminum chloride. In the case of using the electrochemical method, a solution, in which pyrrole or its derivative is dissolved together with ferrocene derivative, is used, as an electrolytic solution, alone or together with a solution in which an electrolyte of inorganic salt such as ammonium salt, lithium perchloric acid and tetraalkylammonium perchloric acid is dissolved. The composite is a superior conductive composite exhibiting an electrochemical activity by virtue of reversible oxidation-reduction reaction of conductive polymer itself and having a high density of electrochemically active material by virtue of an addition of an electrochemical activity obtained by the oxidation- reduction reaction of ferrocene added as an electrolyte.

Title: Target channel verification in a radiotelephone system
Inventor: HULSEBOSCH THOMAS G
IPC: H04W36/08
Filed: 1992-02-25
Abstract: A radiotelephone system verifies the carrier/interference (C/I) of a selected target channel before handoff. The subscriber (125), communicating to a source base-station (130) on a source channel, measures the received signal strength indication (RSSI) of a target channel at a target base-station (135) when the channel is keyed (transmitting) and dekeyed (not transmitting). The subscriber (125) transfers the measurements to a source base-station (130) which determines the ratio of the RSSI with the keyed channel (C) to the RSSI with the dekeyed channel (I). If the ratio is greater than a predetermined threshold, the source base-station (130) transfers the subscriber (125) from the source channel to the target channel at the target base-station (135).

IPC: H04B10/2531
Filed: 1994-04-19
Abstract: An optical communications system has a transmission path including an optical communications fibre 2 having an input port 3 and an output port 4. A compensating element 5 to compensate for a perturbation such as soliton jitter noise in an optical signal transmitted along said transmission path is coupled to the output port, which introduces dispersion of equal magnitude but opposite sign to that of the signal which has passed through system 1.
