Patent DE-3106699-A1 (DE)
Title: Vehicle brake system formed from pressure medium and eddy current brake
Inventor: MAYER HANNS-PETER ING
IPC: B60T13/74
Filed: 1981-02-23
Abstract: A vehicle brake system formed from a pressure medium and eddy current brake is proposed. In the event of full braking it is intended that the coils (12) of the eddy current brake (13) be automatically switched off in order to avoid over-braking. For this purpose pressure medium switches (34 to 37) are used, the connections of which are connected to a brake line or to a brake cylinder (11). <IMAGE>

Title: Knife, especially for making incisions in gingivectomy
Inventor: ZAKRZEWSKI EDWARD LESZEK
IPC: A61C3/02
Filed: 1981-02-24
Abstract: The invention relates to a knife, especially for making incisions in gingivectomy, or similar knives having an elongate handle which is connected on one of its ends to a head via a curved shaft, the head having a slot which accommodates the blade and extends at right angles to the shaft, the improvement residing in the provision of a blade attachment arrangement comprising an elongate, laterally flexible means which extends between the handle and the head inside a cavity extending through the shaft, and a mechanism coupled to the handle and being capable of interacting with the elongate means adjoining the handle in order to interact with the opposite ends in the slot for clamping a blade. At the same time, the elongate means can be a uniform member, e.g. a wire, or a series of individual parts, e.g. ball bearings. The mechanism can be a pressure spring acting between the handle and the elongate means, or a screw element movable in the handle for actuation of the elongate means. The elongate means can be enveloped in an elastomeric material at least on its ends in order to seal the associated cavity.

Title: Formwork panel for receiving hardenable construction materials
Inventor: EGER FRIEDRICH
IPC: E04G9/05
Filed: 1981-05-06
Abstract: Formwork panel or formwork element for receiving and sealing formable or stampable construction materials subjected to a setting process, the formwork panel being coated at least on its inside by such a plastic material that repellent and non-adhesive properties with respect to the construction material introduced and furthermore water-impermeable properties result. The covering (3a, 3b, 3') can be welded abutting at right angles or welded and adhesively bonded in a mitred manner to form sharp edge transitions with lateral covering elements; in addition, to seal the formwork panels after damage by nails or the like, it is possible to provide an additional elastomer layer between the plastic covering and the formwork panel inside.

Title: Process for producing annular rim cores and an apparatus for carrying out this process
Inventor: MERTENS HELMUT
IPC: B29C39/12
Filed: 1981-09-29
Abstract: The invention relates to a process for producing annular rim cores by filling a polyurethane mixture into an annular tube consisting of plastic film, which is arranged beforehand with its circular ring plane approximately perpendicular in a shaping mould, is left in it during the reaction time of the polyurethane and is removed from it once it has cured. The invention is based on the object of providing a process of the type mentioned at the beginning which ensures in a cost-saving way the production of rim cores which are virtually completely smooth on their outer surface and are therefore endowed with high strength, without air inclusions. This object is achieved according to the invention by rings of film being punched out from a double-ply film web and welded to one another at their outer and inner circumferences to form a tubular ring which, with a filling opening at the top, is laid in the shaping apparatus. The process according to the invention can be applied to all forms of rings in which ring-shaped film tubes are to be filled with polyurethane. <IMAGE>

Patent DE-3215251-A1 (DE)
IPC: B60M7/00
Filed: 1982-04-23
Abstract: In sliding-contact line systems there is the requirement to change the sliding carbon contact (211) wear component forming part of the current collectors (21) with such promptness that an unmonitored failure of loads supplied via the current collectors (21) is avoided.   For this purpose, it is proposed to assign a mechanical pulse trigger (31) to the sliding-contact line (11, 12), which trigger is acted upon by the corresponding current collector (21) in the case of advanced wear of the sliding carbon contact (211) and triggers an electric pulse which leads to an indication of the requirement for the sliding carbon contact (211) to be changed. <IMAGE>

Title: Method for transmitting television signals
Inventor: DIRR JOSEF ING GRAD
IPC: H04N11/00
Filed: 1982-06-22
Abstract: To avoid the bandwidth being too wide and for error-free hue and saturation signal transmission, the picture elements are impressed once directly on the half-waves or periods of an alternating current, the voltage value being included in the amplitude of the half-wave or period. The hue and saturation value is also transmitted serially or in parallel with an alternating current of the same or different frequencies. This prevents the phase errors occurring with quadrature modulation.

Patent DE-3233946-A1 (DE)
Title: Barrier post for a car park
Inventor: JUNKER WILHELM
IPC: E01F13/08
Filed: 1982-09-14
Abstract: The barrier post (10) for a car park has its main part in the form of a swing part (13) which is connected by means of a universal joint (14), so as to be able to swivel on all sides, to a holding pin (12) which in turn is fastened to a base plate (11) which is anchored firmly to the ground. The swing part (13) and the holding pin (12) have the same cross-sectional shape and the same outer cross-sectional dimensioning. The swing part (13) is provided with a locking sleeve (15) for locking purposes, the hollow space of which is matched to the outer shape of the swing part (13) and of the holding pin (12). The sleeve can therefore be displaced on the swing part (13), beyond the universal joint (14) and down over the holding pin (12), and then holds the swing part (13) firmly in its vertical operating position. To bend down the swing part (13), the locking sleeve (15) is pushed up beyond the universal joint. A lock (16) at the upper end of the swing part (13) allows the locking sleeve (15) to be locked in the locking position. The holding pin (12), the universal joint (14) and the swing part (13) are made of metal and have a certain minimum strength. The locking sleeve (15) is made of a material, in particular of plastic, with very slight toughness and whose resistance to breaking is less than that of the other parts of the barrier post, the result being that, in the event of an accident, at most the very inexpensive locking sleeve (15) would be broken ...
