Abstract: Cultivator, especially subsoiler, for combination with a following soil-working machine which is driven from a power take-off shaft and which has a central supporting beam which extends transversely relative to the direction of travel and to which are fastened the downwardly projecting cultivator hafts possessing at their lower end laterally projecting wing coulters for soil loosening, and having upper and lower three-point coupling connection elements which are fastened to the supporting beam and by means of which the cultivator can be coupled to the three-point power lift of a tractor or to other machines. To make it possible in a simple way for the cultivator to work without becoming clogged, the particular aim being to prevent soil or bits, such as straw, etc, located on the ground from sticking to the cultivator haft, a vertically extending coulter blade (22) having a width extension (25) transverse relative to the direction of travel is arranged respectively on the cultivator hafts (11) and/or coulters (17) directly adjacent at least to the lower three-point coupling elements (8, 9), and the coulter blade (22) is turned on itself, specifically in such a way that the soil and/or soil bits sliding upwards along the coulter blade (22) are guided past the cultivator haft (11). <IMAGE>

IPC: B07C5/342
Filed: 1990-11-26
Abstract: A sorting machine is disclosed in which a viewing window is electro-optically observed using an array of photodetectors, each observing a photo site or pixel of the viewing window. Each photodetector, and thus each photo site can be normalised individually to account for background and photodetector sensitivity differences from photo site to photo site. The machine can sample the outputs of the photodetectors sequentially and, by deriving respective binary "pass" and "fail" signals and supplying these sequentially to the serial input of shift register 100 incorporated in processing means can reject products affording a series, of more than a predetermined number, of "fail" signals and thus reject products that have a larger than acceptable number of adjacent defective photo sites. Also disclosed is a circuit (Figures 3 and 4) for rejecting a defective product based on sensing where its trailing edge is or should be if covered up by a successive overlapping product. Such detection also allows for rejecting products that are either too long or too short. All of this is done by digital processing resulting from the digitizing permitted by photo site detection.

Abstract: Apparatus for measuring the phase difference between input signals X₁ and X₂ of equal frequency comprises quadrature sampling circuits, such as Digital Radio Frequency Memories (DRFMs) 1 and 3, having a common local oscillator 13. Analogue to digital converters 29,31,33,35, having a common sampling clock 37, are provided for digitising the in-phase and quadrature samples. The digitised samples are used in look up tables 39 and 41 to provide values of instantaneous phase which, preferably using modular arithmetic, are used to derive in an arithmetic circuit a number of values of phase difference between the signals X₁ and X₂. 
     The mean of the number of values of phase difference is then determined by the use of an accumulator circuit operating in conjunction with a divider circuit which is clocked at a sub multiple of the sampling clock 37. 
     In an alternative embodiment for higher speed operation, the analogue to digital converters 29,31,33,35 and look up tables 39 and 41 may be substituted by comparators arranged to detect the polarity of the samples and to provide a binary 1 or 0 to indicate the phase of the samples.

Abstract: Safety cable is used to prevent loosening of threaded fasteners. A multi-strand cable (50) is strung through holes in the fasteners and is held in place by sleeves (60) which are crimped over the cable ends. The cable dampens vibration better than solid wire, which is used presently, and, for a given weight of cable, provides greater strength than solid wire, thus saving weight, which is important in aircraft applications.

Abstract: The invention relates to a telephone system with which a connection between two subscribers can be established, at least one of them being a mobile subscriber. The system includes a paging network composed of one or several exten­sive paging ranges, each of them having a paging transmitter (Hl,H₂) of its own, a small cellular network with an exchange and a plurality of base stations (T), and mobile telephones with which a pager has been integrated. When calling a mobile telephone, the transmitter of the paging range in which the telephone is known or assumed to be transmits a paging message to the telephone, whereby, when the telephone is in the neighbourhood of the base station, the exchange of the cellular network establishes immediately a connection between the subscribers. No paging calls are lost because they are stored in the exchange of the cellular network, and on an appropriate occasion the pager of the telephone and the exchange compare the paging messages stored in the memories. In the disclosed system the call can be transmitted from one base station to another during the call (handover).

Abstract: An electrical connector (10) for connecting liquidtight flexible electrical conduit (16) to an electrical component such as a junction box or outlet, comprises a two-piece, all plastic construction. The connector comprises a plastic body (12) and a plastic gland nut (14) threadably attached thereto. The body (12) includes a plurality of flexible fingers (46), each of which has thereon a pair of friction-reducing ridges (52) that engage an inner contact surface of the gland nut (14) in tangential, point-contact. As such, upon tightening of the gland nut (14) on the connector body (12), the gland nut (14) engages the resilient fingers (46) with minimal friction loss, thereby enhancing hand tightening or minimizing the torque required with a tightening tool. In addition, the connector body (12) includes an inner tubular ferrule (34) which defines a conduit supporting surface (40) which includes thereon friction-reducing elements (42). Such friction-reducing elements (42) permit greater hand insertion and stretching of the conduit (16) onto the connector body (12) to achieve a liquidtight seal between the inner surface of the conduit (16) and the connector body (12).

Abstract: The imaging flow cytometer images and analyzes particle components (such as blood and urine) in a sample liquid, or fine particles of organic high polymer in suspension or the like. A conventional particle imaging flow cytometer is modified to include an image intensifier (38) with a high speed gate function, so as to obtain a clear particle image which is not blurred. Preferably, the light source (28) produces incoherent light, e.g. the light source is a xenon lamp, so that the particle image does not have an interference fringe. Because of the high speed gate function of the image intensifier (38), it is possible to obtain, even when using a light source of long illumination time, a clear still image of a particle flowing at high speed.
