Title: Holding plate for vehicle number plates
Inventor: UNGER BERNHARD
IPC: B60R13/10
Filed: 1986-12-24
Abstract: The holding plate, which is shown in cross-section, has a plate base body (2) with intermediate webs (5) which form a common contact surface (6) for a number plate, which surface (6) is bounded on the outside by means of wall webs (3) which exhibit on at least one side of the baseplate (2) a fixedly moulded-on holding flap (9) at a vertical distance from the contact surface (6) to permit the positive gripping of a number plate (8) from above. On at least one holding plate edge there are, however, moulded gripping flaps (11) which project downwards in a barb-like manner and the ends (12) of which are rounded off. The number plate can therefore, after insertion beneath a number of holding flaps, be pressed by its edge from above to a position below the barb-shaped gripping flaps and held there by the action of a spring. This is especially suitable for use with number plates, which must remain replaceable, for a short period. Securing is by means of a U-shaped clamping strip (14) which can be fastened to the baseplate, in different positions, by means of lock recesses (22, 23) and saw teeth (18, 19). The number plate is therefore held at a plurality of levels of security by different means. At least in the final holding level, it cannot be released without destroying the engagement means of the holding plate. <IMAGE>
Patent DE-3701275-A1 (DE)
Inventor: PIRDZUNS ROLF
IPC: H01H77/04
Filed: 1987-01-17
Abstract: The invention is directed to an overcurrent-protective switch for household appliances such as a vacuum cleaner. The snap switch has a housing in which a contact mounting unit is mounted at one end of the housing and contains one of two current terminals of the switch. The other current terminal is mounted at the other end of the housing and is configured to define a contact-engaging surface. A resilient interrupting contact member is fixedly connected to the one current terminal and has a metal center strip by means of which it is held in one of two end positions. In the first end position, the contact member is held in contact engagement with the contact-engaging surface of the other current contact terminal and, in the second end position, it is disengaged from the contact-engaging surface. When the center resistance strip is cool, the contact member is in its first position and the current circuit between the two current terminals is closed. On the other hand, when excessive current passes through the center strip, the latter heats and expands causing the contact member to snap over into the second position to interrupt the current circuit between the two current terminals. A reset plunger returns the contact member to its first position.

Inventor: MIHAILESCU EUGEN
IPC: F24J2/52
Filed: 1987-09-18
Abstract: The known solar-powered systems differ from one another predominantly as a result of the solar cell area and the storage capacity. The automatically trackable solar-powered system of briefcase size offers the possibility of increasing the solar cell area of aligning it uniformly and electromechanically with the sun and of tracking the sun by sensibly accommodating the solar modules inside a solar cell carrier unit which can be moved along two axes and is inside the solar case. The solar-powered system according to the invention consists of two solar cell fans (80) which are joined to form a uniform horizontal solar cell carrier unit after the solar case (1) has been opened via the joint (40). The solar cell carrier unit is subsequently moved to the active level by means of a setting and extension system, the solar modules are unfolded and aligned with the sun by means of an automatic aligning or tracking device. After the active use has finished, the solar cell carrier unit is moved back into a horizontal position, the abovementioned operation is reversed and the solar case is closed. The solar-powered system according to the invention also corresponds in terms of power and design to sophisticated demands as to use of leisure time and accommodation. <IMAGE>

Patent DE-3801706-A1 (DE)
Title: Structure-borne noise protection means for electrical equipment installed in walls
Inventor: MANTEL JUVAL DR ING
IPC: H02G3/12
Filed: 1988-01-21
Abstract: Electrical equipment installed in walls can transmit structure-borne noise loudly to neighbouring flats (houses). Door bells and telephone bells, electrical switches and other components which produce sound are non-positively fixed to the walls, preferably in wall box openings, but without structure-borne noise insulation. The fixing procedures are preferably carried out by spreading apart pointed prongs which have contact between the electrical articles and the wall as main structure-borne noise bridges, or further noise bridges which it is expedient to prevent can be established through the retaining design. The solution consists in that an intermediate box is installed between the articles to be installed and the wall, which box both is soft enough to prevent transmission of structure-borne noise and also has hard parts, for example a coil made of sheet steel with a thickness of from 0.2 to 0.3 mm which prevents the soft material from being pierced or destroyed by the prongs being spread apart and thus re-establishing noise bridges.
Patent DE-3801733-A1 (DE)
Title: Sound damper which is intended for doors and can be retrofitted
Inventor: MANTEL JUVAL DR ING
IPC: F24F13/24
Filed: 1988-01-21
Abstract: Doors which work in conjunction with ventilating systems have to have openings, so that replenishing air can flow, for example, into baths or other wet rooms. The sound escapes out of the wet rooms through openings of this type. In order to avoid this transmission of sound, sound dampers can be installed in the doors. The invention is based on the fact that, without changing the door opening (usually 180 cm<2> in Germany) for the replenishing air flow, an additionally insertable sound damper can be fitted at a later date. This sound damper according to the invention results from the combination of the deflection of sound, once or a number of times, with a channel (Figures 3-6) which is clad in a sound-absorbing manner, and is suitable for sound damping of 15-60 dB and thus also for sound-insulating doors. <IMAGE>
