Abstract: The support grid for a lying, reclining or sitting furniture, particularly for a bed, according to the present invention comprises a plurality of support elements (1), e.g., laths, and at least two spring bodies (2), the latter being positioned transversely to the laths, the laths rest on the spring bodies and are fastened thereto. The laths have in cross-section a curved support under surface and are so fixed to the spring bodies that they can be pivoted to a limited extent with respect to the spring bodies about an axis running parallel to the longitudinal lath axis. As a result of this pivoting possibility each lath is given a further degree of freedom making it possible for it to adapt further to the shape of a body resting on the lath grid than is possible through the elasticity of the spring body. This increases the lying of sitting comfort of the support grid according to the invention.

Abstract: A feed mechanism for an injection device having an ampoule casing (13) includes an outer casing (2), an inner casing (3) protruding rearwardly from the outer casing and a toothed rack (4) longitudinally displaceable with the inner casing against the force of a spring (8). The rack has teeth (5) of which the length L corresponds to one full injection dose. The inner casing is longitudinally movable by a length L between two stops (6, 7) in the inner and outer casings. The inner casing has a latch (9, 10) which detachably locks the inner casing at its extreme forward position into an aperture (11) of the ampoule casing. A pawl prevents return movement of the rack.

Abstract: A non-sterile ultrasonic-Doppler unit (400/500/600) for locating and puncturing blood vessels is at least partly packed sterile with a sterile device (100/200/300), such that it can be used in a sterile field. The probe (600) of the ultrasonic-Doppler unit, has a slot (610) orientated in the axis of the ultrasonic field and is inserted into a sterile cap (300), causing a guide tube (340) for the puncturing needle penetrating this cap to lie in the slot of the probe. The device envelopes the probe completely, such that the non-sterile ultrasonic probe (600) does not contaminate the puncturing needle, the patient's skin nor the surgeon. The cap (300) can contain a coupling member, which guarantees ultrasonic coupling between the probe (600) and the patient's skin, such that the surgeon need not add any gel. All parts of the device are disposable single-use articles.

Abstract: A measurement circuit in the output circuit of a sensor detects the polarity of a source to which a load is connected. The detection of one of the two polarities establishes one of two states which is stored in a storing element and the correct one of two drivers is switched to the output terminals. This state is maintained for as long as there is no change to the polarity at the output terminals. If the terminals are interchanged, then the measurement circuit correctly restores the stored state, so that the correct driver is associated with the load in each case. If positive instead of negative switching sensors are required, there is no need to replace the equipment. When the voltage is turned on, the equipment is initialized, so that it is set in accordance with the new circumstances.

Abstract: A gripper for handling printed product rolls and empty roll cores is used for intermittently storing printed products wound on roll cores. The gripper has a central piece (10), which is fixed to a conveying or transporting device and which carries a gripper arm star or spider (20). On the gripper arm star (20) is a substantially circular array of radially movable roll clamping devices (30) for clamping a roll or rolls (W) from the periphery thereof and core supports (40) for engaging and supporting a rosette-shaped arrangement of juxtaposed roll cores (WK). The core supports (40) are pivotable so that, in a core handling configuration of the gripper, they are positioned within the circle formed by the roll clamping devices and in a roll handling configuration of the gripper they are moved out of that circle. The movements of the gripper parts are driven by linear drives and monitored by sensors, so that the gripper can operate in a fully automated manner.

Abstract: An imitation weatherboard assembly has two or more weatherboard elements (1) of plastics material which simulate overlapped weatherboard and a preformed backing sheet (11). The backing sheet (11) has a front surface (12) which, in use, abuts the back surface of the weatherboarding elements (1), the front surface of the backing sheet being formed to conform to the rear profile of the imitation weatherboarding elements so that the backing sheet (11) establishes contact with a significant portion of the rear area of the weatherboard elements. A planar edge (8) along the upper edge of an element (1) engages a slot (13) formed in the front of backing sheet (11).

Abstract: The femoral component for a hip joint prosthesis has an intramedullary stem having a free distal region, a proximal region extending to a neck for receiving a ball head, a medial side and a lateral side.The stem has screw holes extending from said lateral side to said medial side for receiving bone screws in the lateral to medial direction for fixation of said stem to the medial cortex. The stem is coupled primarily to the medial cortex of the femur and only secondarily to the cancellous portion of the proximal femur to aid the rotational (torsional) stability of the implant.

Abstract: A high-power relay with a low-power operating circuit is usable in combination with a low-current source of DC power. The source has a hot terminal and a common terminal and a bistable relay has an energizing relay winding with one terminal of the winding connected to the common terminal of the supply. First and second semiconductor switches are connected to a second terminal, the switches being alternately operable in response to control signals to respectively set and reset the relay. First and second capacitors are connected to the first and second semiconductor switches, respectively, and first and second charging circuits are connected to the low-current source and to the first and second capacitors, respectively, to charge the capacitors from the source. The switches are connected to selectively discharge the capacitors in opposite directions through the energizing relay winding thereby to SET and RESET the relay in response to control signals. A method of operating the circuit is also disclosed.

Abstract: A sequence of documents is delivered to an optical scanner in which each document is scanned to form a digital image representation of the content of the document. In one embodiment, the image representation is converted into code (ASCII) and is automatically examined by data processing apparatus to select search words which meet predetermined criteria and by which the document can be subsequently located. In another embodiment, the image is not converted. The search words are stored in a non-volatile memory in code form and the entire document content is stored in mass storage, either in code or image form. Techniques for selecting the search words are disclosed, including establishing a font table and constructing images of entered search words from the table.

Abstract: The inventive core for electrical connecting substrates, particularly for printed circuit boards and foil circuit boards, has an inner layer (I) with a columnar structure and on either side, metallic cover layers (A,A'), the columnar structure of the inner layer (I) comprising columns (9.1,9.2), which are regularly arranged, spaced from one another and from the cover layers (A,A'), being directed transversely to the service extension of the core and made from an electrically conductive material in a matrix (6) of an electrically insulating material. The cover layers (A,A') e.g. have electrical terminals (16,16', 17,17') in the form of through-plated blind holes (13,14) on selected columns (9) of the inner layer (I) and are structured in such a way that they have a regular pattern of terminals (16,16') on the facing cover layer and terminals (17,17') on the through-connections insulated from the cover layers, this grid pattern can have a size of approximately 0.5 mm.

Abstract: A lock cylinder with key, in which the cylinder has a rotor and a stator with radial tumbler pins and the key has depressions corresponding to the tumbler pins. At least one tumbler pin functions as a control pin (K), in that a zone produced by an offset provides a side coding (F) in addition to the depth coding (T) with a diameter corresponding to an additional coding (B) and the associated key has a depression with sides (8), whose spacing between the sides corresponds to the coded diameter (B) of the control pin offset and whose tumbler pin cooperates on the one hand with the milled coding in the key and on the other hand with control faces formed in the key blank. The aim is to create a copying or forging obstacle by means of a technical measure in the cylinder and on the blank.

Abstract: In a metal-clad laminate the requirements concerning the mechanical strength are functionally separated from the circuit connection requirement, so as to be able to bring the circuit connection, particularly for signals, "closer" to the electrotechnical characteristics of the chips. For this purpose and without taking account of the mechanical strength of the substrate, the layout miniaturization is optimized. In place of a circuit board (MCM), a laminate which can be built up to a circuit board is produced. The inventive laminate comprises an extremely thin foil with a plurality of extremely small holes simultaneously etched in an etching process. The hole diameter can be reduced by almost an order of magnitude (up to 20 .mu.m), which permits a sub-100 .mu.m technology. Such a laminate is not used as a mechanical support and is only provided for signal guidance. The effect of the miniaturization can be seen in the diameter for the plated-through holes.

Abstract: A marine vessel waste treatment system includes a tank for receiving successive charges of liquid and solid waste material. A water conduit conducts heated water from the vessel's engine through the tank to heat the contents thereof above the level at which coliform bacteria can survive, thereby reducing the count of such bacteria to a level at which it is safe and acceptable to discharge the material into a waterway. A macerator pump is mounted in the tank for operation only after the temperature within the tank is sufficiently high. An electrically operated heating element is also mounted in the tank to accelerate the treatment of waste and can be used alone when desired. A thermal switch at the waste material input inhibits discharge if a fresh charge of material is received when the system is ready to discharge, thereby preventing discharge into the environment of untreated material.

Abstract: Rotating beverage receptacle-filling equipment for filling receptacles has receptacle sites spaced along its periphery and metering containers which can be filled from a beverage tank. Beverage is discharged from the metering containers into the beverage receptacles. A control system recognizes upper and lower liquid levels in the metering containers to control the discharge volume. The metering containers are transparent and at least one stationary video camera observes the metering containers of several adjacent receptacle sites. An image analyzer continuously monitors the metering containers in the field of view of the camera while detecting the levels in different angular positions at the receptacle sites and generates control signals for valves at the receptacle sites. A camera observes the refill limit level to control a refill valve and a camera observes the discharge limit level to control a discharge valve.

Abstract: Tubular packs, which contain a wound scale formation of flat products, particularly printed products, are conveyed over predeterminable conveying paths from at least one pack-producing apparatus (W.multidot.1, W.multidot.2) to at least one forwarding or intermediate storage station (A). For this purpose the packs are conveyed away from the pack-producing apparatus (W.multidot.1, W.multidot.2) with axes oriented in the conveying direction in a longitudinal conveying direction (FP.sub.1). Then in a distributing station (VU) or a deflecting station (U) for distributing the packs to different despatch units and/or for combining the packs into identical despatch units the conveying direction of at least part of the packs, for a constant axial position, is modified by substantially 90.degree. into a transverse conveying direction (FP.sub.q). Combined packs can be compressed in a combining station (ZU) and bound together to form double or multiple packs (PP) using a wrapping means.

Abstract: An individual identification system is a modular combination of a person-related first unit with transmittable/receivable storage elements by way of an antenna, the unit operating alone or together with a further unit having an additional, but different, identification part, and a person-unrelated and instead object-related second unit for the interaction between the person and the object and with a control for checking and maintaining the interaction with which units and objects are crosslinked. The person-related first unit is carrier oriented and is permanently or removably located on a use article, e.g., on a key, in a pass, on or in a watch or any other object which changes position with the person and is not coordinate-fixed. The object-related second unit is place-oriented and is at fixed locations (e.g. building doors), or is arranged in fixed manner on moving objects (e.g. vehicles).
