Abstract: A method for severing the heads from fish makes a better yield of fish flesh supplied for human consumption possible. In this method the supracleithra forming the connection between the head skeleton and the shoulder girdle arcs are split off after the gill cavity has been opened ventrally by cutting through the isthmus and finally the head is pulled from the rump in a position where it is jack-knifed towards the nape of the neck.

Abstract: A periodontal pocket irrigating and treatment system includes a dispenser capable of containing a medication. The system enables an individual patient to self-administer a medication or irrigant into periodontal pockets while at home or travelling. A housing holds a tube of medication, and a roller squeezes the tube, thereby releasing an incremental portion of the medication therefrom. A control, operable from the outside of the housing, urges the roller in increments along the interior of the housing, squeezing the tube in a controlled fashion. A nozzle is attached to the tube for delivering the medication from the tube through a nozzle outlet end of small diameter to the periodontal pocket. Optionally, a flexible tip is attached to end of nozzle for elimination of pain and for guidance around curvatures of the periodontal pocket. A ratchet preferably controls the amount of medication dispensed by the device.

Abstract: A hood for an electrical connector employs a pair of identical body porti which are mated together to grasp the electrical connector and to provide strain relief to the exiting conductors. Strain relief is provided by a resilient or flexible strain relief tab extending angularly inward from an inner surface of each of the body portions. The strain relief tabs have sufficient resilience to permit outward deflection thereof as necessary to handle a substantial range of cable or wire bundle diameters. An optional bifurcated tip on the strain relief tab doubles the contact lines with a small cable and improves the ability of the tip to conform to the shape of a small cable or wire bundle. Ridges on the strain relief tab engage the surface of a large cable or wire bundle. The ridges may be sawteeth which are angled to resist outward forces on the cable or wire bundle. Exit channels are provided for cable exit either axially or in either of two transverse directions.

Abstract: A fish guiding device is provided for guiding fish for processing in fish filleting machines particularly before and during the fish processing cut. The device includes guiding elements which engage the flanks of the fish and are spread apart by the latter in a counter-directed pivoting movement. The guiding elements are provided with a further degree of freedom in the form of a counter-directed swivelling movement about an axis extending substantially parallel to the fish path. Such movement enables the guiding elements to adapt to the flanks of the fish fed between them and positions the ventral fin in a precise position for removal even when the belly opening cut runs unsymmetrically.

Abstract: The invention concerns a device for the automatic supplying of fish uniformly aligned with respect to their belly-back position to fish processing machines, which device comprises a belly-back aligning section, from which the fish is delivered to a processing machine in a timed manner. It is the object of the present invention to universalize the scope of use of known belly-back aligning sections in order to enable the handling of the great percentage of damaged fish which occurs due to set or drift net fishing. The increased danger of blocking of such aligning sections by damaged fish is avoided according to the invention in that the passage for the fish through the aligning section is opened by force shortly before the arrival of the next fish, respectively.

Abstract: The invention relates to a device for raising fish into uniform belly-back position. To improve the effect of an uprighting station comprising a guiding chute for the fish lying on their side and a controlling edge arranged above the longitudinal center of the guiding chute to yield resiliently, it is suggested to form the controlling edge as a periphery of a rotatingly driven circular disk. The repulsing effect realized under the conveying operation effects a secure aligning of the fish even when their quality is influenced by distortions and deformations or damages in the head area, and also makes it possible to raise headless fish.

Abstract: A computer terminal support includes two vertical posts about which respective pivoting collars are free to pivot. Each pivoting collar is affixed to a swivel arm. A terminal support tray is affixed to an outer end of the outer one of the two swivel arms to thereby provide a substantial coverage area over which the computer terminal may be disposed. A vertical adjustment of the position of the outer pivoting collar on the outer vertical post is provided in order to permit adjustment of the vertical position of the display screen of the display device of the computer terminal. A horizontal pivot and a vertical pivot are provided for rotation of the computer terminal and its associated display screen of the display device in order to permit angular adjustment of the display screen anywhere within the coverage area for avoiding interference from glare.

Abstract: A device for arranging fish in uniform head-tail alignment comprises a rotating gripping device of radially arranged pincer-like gripping elements. These form a vertical slot into which the fish led tail end first are introduced. Following the rotation of the gripping device the gripping elements are held closed in a region of a stationary sector of each one revolution so that the tail fin is grasped and the fish carried along thereby. After passing the highest point of the revolution of the gripping device the fish turns over under the effect of gravity and is then released head end leading. Fish led head first cannot enter the slot because of their thicker heads and are passed on directly.

Abstract: The invention concerns a device for processing fish and introducing the same into cans. It is characterized in that the fish are placed in alternating alignment in threes or fours in troughs of a conveyor which comprises one middle trough element flanked by two outer ones and whose support surface comprises a base plate raisable and lowerable by the force of a spring. The fish brought onto the base plate are guided to a cutting device which cuts out the rump pieces of the fish and which is adjustable with regard to the desired fish length. Subsequently they are gutted by the use of low pressure. The transfer of the fish into the cans held ready in time with the troughs occurs in the lower run of the conveyor, maintaining the packing pattern predetermined by the introduction into cans by lifting the base plate. In that process the can supply is monitored such that each can is only confronted with a full trough.

Abstract: Apparatus for spraying plants with liquid treatment chemical such as an insecticide, fungicide, herbicide or the like, includes a reusable container having inlet and outlet hose connections, and a disposable cartridge which is inserted into the container. The cartridge comprises a pressure-sensitive container in the form of a piston cylinder or a collapsible bag containing the liquid chemical, and is mounted within a rigid casing or jar communicating with a stream of water under pressure entering the inlet hose connection. The water also flows through an axial bore in the head of the reusable container to the outlet hose connection, passing from a high pressure side through a mixing chamber to a low pressure side.

Abstract: An electrode and a lead wire therefor used with a device for measuring the electrical signals emanating from a living body, such as a cardiograph or electroencephalograph employed for examination and diagnostic purposes. The electrode consists of two layers of finely divided electrically conductive material, that are printed in laminated fashion on the opposite surfaces of an insulating film. The lead wire comprises plural laminated layers of finely divided electrically conductive material on the opposite sides of an insulating film, the laminated layers being interspersed with or encased by carbon layers and insulating layers. Since X-rays penetrate the electrode and the lead wire, an X-ray photograph may be taken during visual inspection of the biosignals without the image of the electrode and the lead wire appearing on the film to hinder diagnosis.

Abstract: The invention concerns the gilling area of needle bar drawing devices (gill boxes) for card slivers which gilling area comprises needle bars provided with needles, carried by flexible driving elements and rotatingly driven. In a gilling area whose needle bars are carried by belts, especially toothed belts, as driving elements, it is suggested to arrange support elements for the needle bars to be clamped positively to the driving element.

Abstract: A periodontal lavage syringe is provided for self home use by an unskilled patient in the treatment of periodontal disease by irrigation of periodontal pockets or other soft tissue spaces. The syringe may have a single liquid retaining barrel or preferably multiple barrels, each of which contains a dispensible plunger and each of which is filled with a different treatment fluid. The bores communicate with a single liquid outlet to which is attached a flexible needle or tube terminating in a nozzle which is preferably elastomeric. The nozzle is conical in shape, having a pointed tip which enables easy insertion of the nozzle into the periodontal pocket, and tapered walls, the increasing diameter of which limits the depth of insertion of the nozzle within the pocket.

Abstract: A control device for the processing tools controlled by cams with regard to their start of operation and their processing course is provided in fish-processing machines. The cam comprises, as already known, a main cam and one or more cam segments adjustable on the main cam. To enable a quick and easy adjustment of the tools even while the machine is running and thus achieve optimum working efficiency and results, the cam is so constructed that the main cam is associated to a coupling member via an intermediate drive by means of a chain or toothed-belt drive, the coupling member itself being associated to the cam segment(s). A change in the position of the cam segment 17 relative to the main cam 15 when the machine is running may be performed by changing the spreading of the chain or toothed-belt drive which connects the intermediate drive with the coupling member 34.
