Abstract: A motor vehicle seat has a base element which can be fastened in the motor vehicle, a seat element which is disposed on the base element, and a backrest element which is disposed on the seat element. The seat can be adjusted between a locked position and an unlocked position. In the locked position, the seat element and the backrest element can be used for normal sitting. In the unlocked position, the seat element and/or the backrest element are adjusted in the vehicle to the front with respect to the driving direction far enough so that a space arranged behind the seat with respect to the driving direction is accessible for loading and unloading. For adjustment between the locked position and the unlocked position, the seat element is swivellably disposed on the base element and/or the backrest element is swivellably disposed on the seat element.

Abstract: A motor vehicle has at least one vehicle occupant seat arranged laterally of a side member. The vehicle occupant seat is arranged on seat rails which extend in the longitudinal direction of the motor vehicle and are fixedly connected by way of a seat underframe with a vehicle floor. The side member and the seat rail adjoining the side member have mutually assigned safety devices which are arranged at a distance from one another in the longitudinal direction of the motor vehicle. The safety devices can be brought into an operative connection with one another such that the seat rail and the side member are connected by way of the safety devices during high dynamic stressing of the vehicle occupant seat and/or of the side member.

Abstract: A vehicle seat has a seat frame which is arranged in a vertically adjustable manner above a seat underframe. A backrest part is mounted on the seat frame, and a seat cushion carrying part, for adjusting the seat cushion depth, is displaceably disposed by an end area in two guides. The other end area of the seat cushion carrying part is supported by two additional guides. The additional guides are supported by way of a supporting construction past the seat frame directly on the seat underframe.

Abstract: A height adjusting device for a lengthwise adjustable vehicle seat is provided. Pivotal control arm units are provided at front and rear position of a vehicle seat to raise and lower the seat in dependance on their rotative position Link assembles, including front and rear coupling arms pivotally connected by an intermediate joint connect the front and rear control arm units.

Abstract: A vehicle seat has a backrest which can be tilted forward about a swivelling axis displaced toward the front with respect to the backrest into an alternate position for facilitating the entry and the exit. The backrest is fixed in its tilted-back end position by way of latching devices arranged on both sides on the seat cushion part, after which the latching devices can be synchronously unlocked in a remote-controlled manner by a common actuating element. For the swivel bearing and for the support of the backrest with respect to the seat cushion part, lateral support fittings are provided, on which, at a distance behind the forward swivelling axis, a hinge is arranged for adjusting the inclination of the backrest. The support fittings each have a rearward-projecting holding leg which ends at a distance behind the assigned hinge of the backrest, the free leg end of the holding leg in the tilted-back end position of the backrest being lockable on the seat cushion part.

Abstract: An actuating device is provided for a vehicle seat whose seat back can be folded forward around a pivot axis into a deflected position to facilitate entrance and exit. The seat back is held in its folded-back end position by bilaterally provided rotary drop latches which can be unlocked remotely by a common actuating element in synchronization and with a tension arrangement being provided for remote unlocking. The rotary drop latches are rotationally coupled by a connecting rod and operably connected by a single tension strand with the actuating element.

Abstract: A weapon barrel includes a liner having first and second circumferential regions; a jacket surrounding the liner; and an arrangement for effecting a heat transfer outwardly from the liner at a greater rate from the first circumferential region than from the second circumferential region.

Abstract: An electrochemical sensor is provided containing a supporting material having a surface of noble metal such as gold or palladium to which is bound an enzyme such as glucose oxidase via binding molecules. The binding molecules are in the form of a homogenous monolayer and are bound to the metal surface by anchor groups such as thiol, disulphide or phosphine groups. The enzyme is linked to the binding molecules by an ionic bond, a covalent bond or a metal-chelate bond. The binding molecules may contain a spacer such as an alkylene chain. Coverage of the binding molecules on the metal surface is less than the maximum coverage to optimize enzyme coverage, decrease response time of the sensor and increase signal yield per surface area. The monolayer may contain diluent molecules which are not linked to an enzyme and which are bound to the metal surface via anchor groups.

Abstract: There is provided a discant string construction for classic and flamenco guitars having a polyfilament core formed of a group of non-twisted with respect to each other synthetic filaments, a first covering layer of metal wire spirally wound in tight contact coils, and a second covering layer of plastic material covering the first layer.

Abstract: A support crucible includes a central axis, outer radii including longest outer radii defining planes with the central axis, a side wall region having a circumferential direction and a bottom. At least two neighboring segments are separated by joints extending substantially vertically in the side wall region to the bottom and penetrating the bottom. The joints define opposed surfaces of the neighboring segments which always overlap each other in the circumferential direction of the side wall region in an operating state. Each of the surfaces is intersected by a respective one of the planes, at least in the side wall region. According to another embodiment, the joints defining opposed surfaces of the neighboring segments have complementary shapes, the surfaces are formed by cuts beginning at a jacket surface of the side wall region and extending parallel to the central axis and at an angle to the planes, and the cuts extend in a curve to the central axis.

Abstract: A seat unit can be screwed automatically to the body platform at four fixing points without the need to alter the seat setting during screwing and has a sufficiently rigid connection, in particular a sufficiently firm connection for seat belts which are fixed to the seat, to the body platform. The fixing regions are provided in the floor rail itself, in particular in each case at a distance from the free ends of the latter and in a profile region, extending essentially parallel to the body platform, of the floor rail. These regions are joined directly to a steep wall and, with the latter, in each case form a ramp, and are oriented such that they enclose as small an angle as possible with the floor rail, although this angle is kept sufficiently large that, in an installation setting of the seat unit, the axes of the holes extend in front of the front side of the seat and behind the rear side of the seat with a clearance of a few centimeters, which makes possible the use of a screwdriver unit.

Abstract: A graphite tube furnace for atomic absorption spectroscopy has a specimen support. The graphite tube furnace is constructed with zones disposed substantially symmetrically around the center of the furnace. The shape of the zones is largely matched and matchable to the functions of the device, such as electric contacting, prevention of heat sinks, restriction of an atomization chamber, provision of an atomization chamber and holding of the specimen support. The specimen support is formed in such a way that in practice it is no longer heated by Joulean heat or thermal conduction, it is secured against movements and it has a minimal mass.

Abstract: A graphite tube furnace and a specimen support are provided for atomic absorption spectroscopy. The graphite tube furnace has end surfaces with slots. The specimen support has an intermediate or middle section with a recess for receiving a specimen and end sections which are wider than the middle section. Upon insertion in the graphite tube furnace, the specimen support is fixed with the wider end sections in the slots in the end faces and the intermediate section is held at a constant distance from the wall of the tube furnace. As a result, current conduction and heat flow between tube furnace and the specimen support are very small.

Abstract: A graphite tube furnace with a specimen support for use in atomic absorption spectroscopy has preferably knife-edged shaped flanges on the inner wall surface of the tube furnace. The specimen support is held on the flanges at a distance from the inner wall surface. This avoids the production of heat in the specimen support and heat flow from the tube furnace to the specimen support.

Abstract: In a passive infrared movement detector having a reflector which directs the radiation from a plurality of fields of vision to an infrared detector arrangement and for this purpose consists of a plurality of individual reflectors, the reflecting surface of the reflector is composed of a plurality of facets produced at the reflector. The disadvantages of such a reflector are in particular to be seen in the fact that for each required distance range of the passive infrared movement detector a reflector adapted thereto must be used. Furthermore, the production of such a reflector is relatively expensive. In order to avoid these disadvantages, the individual reflectors are proposed to be in the form of spherical reflectors which are arranged on a reflector carrier in a manner so as to be shiftable in different directions and lockable in adjusted positions.

Abstract: A recorder contains a rotatably mounted drum which is structured as a vacuum or negative pressure-hollow cylinder.
