The hooks can be attached by screws to a bridge parallel to the busbar, as wide as the housing.
Patent DE-4244250-A1 (DE)
Inventor: TESCH GUENTER
IPC: D06N7/00
Filed: 1992-12-27
Abstract: In a wear-resistant, fibre-reinforced floor covering (1) with a substrate (7) and a layer of cork (2) and a binder (3) thereon, the layer of cork (2) and the binder (3) is arranged between the substrate (7) and a covering layer (6) and the three layers are bonded together by means of needled fibres (4), with the cork (2) in particle form. In order to produce this wear-resistant, fibre-reinforced floor covering, a core layer of cork particles is laid on a substrate, a covering layer is laid on the cork layer lying on the substrate, the three layers are needled together by retaining fibres taken from the covering layer and/or the substrate through the core layer containing cork particles through which they can be passed and, after needling, the floor covering is impregnated with a binder. This provides a floor covering suitable as a substitute for linoleum and which can, however, be made more elastic than linoleum.

Patent DE-4303110-A1 (DE)
Title: Broadcast receiving system
Inventor: BIERE DIETMAR
IPC: H01Q23/00
Filed: 1993-02-04
Abstract: When active antennas are used for mobile receiving systems, e.g. for car radio systems, stringent requirements are imposed on the linearity of the amplifier part and on noise adaptation. This must also apply in cases where antenna overvoltages occur, in the vicinity of powerful transmitters, in urban areas, or where atmospheric discharges occur. However, the tuner input part must be protected against excessively high signal voltages. For this reason, level control is performed in the tuner upstream of the first amplifier stage. However, this has the simultaneous effect that the level obtained in the amplifier part of the antenna is sometimes not fully utilised. A number of further disadvantages of conventional mobile systems are associated with this problem, such as expensive RF cables, in some instances of considerable length, and an arrangement of the individual components in the vehicle which can be improved from an electrical/functional and technological point of view. According to the invention, an adjustable attenuator (7) is inserted into the circuit of the active antenna between the passive part (1) and the noise-adapted amplifier (2) to limit the signal level in the event of antenna overvoltages, and the tuner (3) is physically separated from the receiver and directly connected to the antenna amplifier (2) to form a module. The control voltage for the attenuator is tapped in the signal path downstream of the antenna amplifier (2). With selective attenuation of the antenna signal - i.e. depending on the selected ...

Title: Method and apparatus for regulating the degree of ventilation of tobacco products
Inventor: MOELLER HENING DR
IPC: A24C5/47
Filed: 1993-03-02
Abstract: The invention relates to the regulation of the degree of ventilation of filter-tip cigarettes which are produced using pre-perforated wrapping paper. The object is to compensate for the fluctuations in air permeability produced by differing perforation. This is achieved by means of a rolling device for rolling the wrapping paper around the filter-tipped cigarettes Z, a rolling hand (23), which can be adjusted relative to a rolling cylinder (22), being provided and having an adjustment means (69) whereby the distance between the rolling hand and the rolling cylinder can be changed and the pressure on the rolled filter-tip cigarettes can be varied so that, in the event of excessive air permeability of the perforation, the pressure is increased or the distance reduced, and vice versa. In this manner, the coating of gum applied to the wrapping paper is more or less crushed and hence the gap remaining between the wrapping paper and the wrapped filter end is narrowed or widened. <IMAGE>

Patent DE-4325273-A1 (DE)
Title: Method for manufacturing a wooden workpiece
Inventor: ROTH ANDREAS
IPC: B27B1/00
Filed: 1993-07-28
Abstract: In the conventional glued-binder method, tree sections are divided up into individual boards which are then dried and thereafter successively glued (bonded) to form the wooden workpiece. In this case, the original pattern of the wood structure and wood figure is lost. To design the method such that the natural pattern of the wood structure and figure of the wooden workpiece is retained in a simple way, the boards are marked in the sequence in which they are severed from the tree section. The boards thus marked are glued together to form the wooden workpiece in such a way that thereafter they have the same position relative to one another as before the severing. The wooden workpiece then has the appearance of a naturally grown wood by virtue of the fact that the figure and wood structure extends beyond the scarcely visible glue lines. The wooden workpiece has the technological advantages of a glued binder (binding beam, trough beam). It can preferably be employed in the structural and visible timber sector, wherever it remains visible.
