Abstract: Techniques involve a device which includes an energy chain and a sliding table, the energy chain having a plurality of sliding shoes, each having a sliding surface for sliding on the sliding table. The sliding shoes each have a detection element, which is spaced from the corresponding sliding surface by a wearing layer. The sliding table has a sensor for determining the distance (d) between the sensor and the detection elements.

Abstract: A method and apparatus for manufacturing medical paper for medical sterilization packaging, medical paper and medical sterilization packaging are disclosed. A paper web is formed of fibrous substrate comprising cellulosic fibers and optionally synthetic fibers, with opposite first and second sides. On-line with the forming of the paper web, reinforcing material is applied on the first side and pressed into structure of the paper web such that delamination resistance of the structure is increased. Sealing material is applied on the second side of the paper web on-line with the forming of the paper web.

Abstract: A housing for a telecommunications system is described. The housing contains a housing base for accommodating modules and module frames, and a covering shroud connected releasably to the housing base and, with the housing base, encloses the modules and the module frames. The covering shroud has a casing plate forming at least part of the covering shroud, and plastic moldings connected, in part, to the casing plate and/or the housing base. Some of the plastic moldings can be lined up in a row one beside another to form a wall surface of the covering shroud.

Abstract: Described is a high-frequency surgical instrument with automatic control of the intensity of the electric arcs between the active electrode and the tissue that is to be cut or coagulated, whereby for determination of the extent of the electric arcs, a therefrom dependent signal (K) is shunted off through a filter and conducted to a rectifier whose output signal is conducted to a variable-gain amplifier in which this output signal is compared either with the set-point signal (S) of a set-point device for the cutting process or with the set-point signal (K) of a set-point device for the coagulation process. The variable-gain amplifier generates a signal proportional to the difference of the signals E minus S or E minus K, respectively, which is conducted to an amplitude modulator which controls the amplitude of the output voltage of the power amplifier.

Abstract: A high frequency surgical apparatus for the thermal coagulation of biologic tissues is described, in which for monitoring the fluctuations in amplitude of the high frequency current during each coagulation process a current monitor (25) is provided, which by means of a current-to-voltage coverter generates an electrical voltage proportional to the amplitude fluctuations of the high frequency current, from which voltage, by means of a first detector, a first direct voltage proportional to the amplitude fluctuations is formed and, by means of a second detector acting as a peak value detector, a second direct voltage is formed that rises in proportion to the amplitude of the high frequency current. The first direct voltage (U.sub.a) and the second direct voltage (kU.sub.b), which is divided downward by an adjustable factor by means of a voltage divider, are supplied to a voltage comparator, the output signal of which sets a bistable circuit as soon as the first direct voltage (U.sub.

Abstract: Described is a safety circuit for a high-frequency surgical instrument for the monopolar cutting and coagulating of biological tissue, where the neutral electrode is high-frequency-grounded through a capacitor. The safety circuit monitors the low-frequency leakage current which flows through the capacitor against the ground potential and interrupts the electric connection between this capacitor and ground potential immediately when the low-frequency leakage current exceeds an adjustable limiting value. Simultaneously, an optical signal and an acoustical signal are activated.

Abstract: A biocidal composition based on organic arsenic compounds, comprising at least one tin compound in an amount affective to prevent elution of the arsenic compound from a composition containing them, particularly molding compositions for the production of molded plastic articles, particularly based on flexible PVC and/or ethylene/vinyl acetate copolymers or graft polymers or, optionally, polyethylene, containing stabilizers imparting stability to light, weather and heat, and optionally conventional additives such as colorants, fillers and slip agents, and containing further an arsenic compound as a biocidal agent are treated with such tin compound to prevent elution of the biocidal compound.

Abstract: A supplementary acoustic warning signal is provided for a high-frequency electrosurgical unit which sounds only after the lapse of an interval set by a first delay circuit shows that one of the high-frequency generators in the unit remains active longer than what, on the average, is normal. A second delay circuit is provided to assure shut-off of the high-frequency generators if at least one of the high-frequency generators remains active without interruption longer by an interval set by a second delay circuit beyond the lapse of an interval of the interval set by the first delay circuit. The supplementary acoustic signal thus sounds before the second delay circuit shuts off the high-frequency generators. The intervals determined by each of the delay circuits are adjustable.

Abstract: A sealing sheet for the building industry made up of at least one layer which contains an elastomeric synthetic resin that is devoid of, i.e., free of vulcanization accelerator, and that contains fillers, especially carbon admixed with an ethylene-propylene-diene terpolymer and/or ethylene-propylene copolymer and which has, on the outside and/or between layers of a synthetic resin, a reinforcing layer laminated in place with the use of heat and comprised of a fabric, a mat, a knitted material, a nonwoven material, or a similar material formed of a synthetic resin and/or of glass fibers.

Abstract: A multi-layered sealing sheet for the building industry is prepared so that all plies which contain elastomeric synthetic resins are devoid of vulcanization accelerator and consist of an elastomeric synthetic resin on the basis of ethylene-propylene-diene terpolymers and/or ethylene-propylene copolymers. A reinforcing insert is laminated in between the layers with the use of heat and is a fabric, a mat, a knitted material, or a similar material of synthetic resin fibers and/or glass fibers.
