Patent DE-3136223-A1 (DE)
Title: Integratable audio-frequency detector
Inventor: ROHM PETER DIPL ING
IPC: G01R23/15
Filed: 1981-09-12
Abstract: The integratable audio-frequency detector described exhibits a relatively long shift register (SR) with the aid of which an input vibration, the frequency (fe) of which is to be detected, is sampled. The sampling frequency (fs) is much higher than the frequency to be detected. The binary samples are shifted through the shift register so that a travelling wave of binary values corresponding to the input vibration is produced in this manner. Two logic circuits (L1, L2), the inputs of which are connected to stages of the shift register (SR) and the output signals of which are logically combined with one another by means of an NOR gate (G1), also generate, from waves having different wavelengths, different pulse sequences at the output (A1) of the NOR gate (G1). These pulse sequences are converted by a subsequent evaluation circuit into a yes/no decision which indicates whether the wavelength of the wave which is currently passing through the shift register (SR) has an agreed value within adjustable tolerance limits or not. The statement that the frequency (fe) of the input vibration has an agreed value or not is equivalent to this statement. <IMAGE>

Title: Agricultural trailer implement
Inventor: KRONE BERNARD
IPC: A01B63/22
Filed: 1981-10-08
Abstract: Agricultural trailer implement having two supporting wheels, the wheel-axle carriers of which are articulated on the machine frame so as to be pivotable individually in a vertical pivoting plane about horizontal pivot axes coaxial with one another, are under the preload of a force accumulator in the working position and are pivotable between the working position and a transport position by means of a lifting drive. The force accumulator and the lifting drive are arranged jointly in the region of a first supporting wheel and act on the second supporting wheel indirectly via a pivoting shaft, one end of which is connected to a lever in the effective range of the force accumulator and the lifting drive and the other end of which is connected to the wheel-axle carrier of the second supporting wheel. The wheel-axle carrier of the first supporting wheel is equipped, on its side facing the lever of the pivoting shaft, with an extension, to which movements of the lever of the pivoting shaft can be transmitted. For the simplification of settings, there are as force accumulator a single compensating spring and a coupling member which is under the preload of the latter and which is located between the lever of the pivoting shaft and the extension on the wheel-axle carrier of the first supporting wheel.

Patent DE-3205508-A1 (DE)
Title: Improved heating pipe
Inventor: LAUDE FRITZ
IPC: F28F13/06
Filed: 1982-02-16
Abstract: The energy problem necessitates the further development of known heat pump engineering, and it has also been necessary for this purpose to include the heating pipe in this technology. In the known simple design, the efficiency is too low, and it is only a separation of the evaporation and condensation processes that renders a higher efficiency possible, chiefly due to the fact that larger heat exchanger surfaces are possible - by the use of balls. Furthermore, these balls reduce the flow resistance and facilitate a more intense heat exchange.

Title: Process and apparatus for producing a sports facility surfacing
IPC: E01C13/08
Filed: 1982-07-02
Abstract: Starting with a web of tufted synthetic turf stored in rolled form, the sports facility surfacing is produced by unwinding the web of synthetic turf from the storage roll and feeding it to the prepared bed on the ground of the sports facility, the said web being thermally perforated before reaching the prepared bed, so that the web of synthetic turf becomes water-permeable. The laying movement which takes place in any case is thereby utilised by the thermally operating perforating device as a transporting movement. The perforating device (16) in this case comprises a welding beam (20) arranged underneath the through-running web of synthetic turf and having a multiplicity of welding pins (33) arranged on the said beam. The welding beam (20) is cyclically raised by rotatably driven eccentric discs (23). The welding beam (20) is guided in such a way that it can run along a little with the web of synthetic turf and can return to the lower position under its own weight. <IMAGE>

Patent DE-3243768-A1 (DE)
Title: Surface heating system
Inventor: HERBERTZ HEINZ ING GRAD
IPC: F24D3/14
Filed: 1982-11-26
Abstract: In this surface heating system, the heating pipes are arranged in the immediate neighbourhood of the surface. Hence they can be laid after the screed layer has been completed. In order to produce good heat conduction between the heating pipes and their surroundings, and to guide them during thermal expansion, the heating pipes (1) are laid in grooves (6) which taper in a wedge form towards the surface and which are closed by filling pieces (2). For better distribution of the heat, the heating pipes are covered with a nonwoven fabric (7) of metal fibres. To equalise the large thermal expansion, particularly with plastic pipes, indentations (10) which are filled with the non-woven fabric (7) are provided at the curves of the heating pipes. The nonwoven fabric of metal fibres is compressible and in spite of this conducts heat well. <IMAGE>

Title: Tricycle for conveying persons and goods
Inventor: MESSERSCHMIDT PETER
IPC: B62K5/05
Filed: 1983-02-01
Abstract: The invention is a tricycle for conveying persons or goods on which the part on which the person or the transport container to be conveyed is seated can be uncoupled from the drive part, Fig. 1. The part on which the person to be conveyed is seated is comparable with a conventional wheelchair and can also be used as such. This wheelchair is the steerable part of the tricycle. Thus, the said wheelchair is provided with a rotary joint and connecting element, Fig. 2, P. 1+2 in order to couple it to the drive part. A transport container can be coupled to the drive part analogously to the wheelchair. The range of application of the invention is in the local transportation of predominantly disabled persons. New prospects are created for the inclusion of disabled persons in everyday life in an uncomplicated fashion (e.g. shopping tips) and in leisure activities (e.g. visits to museums, the theatre, cycling tours). As a result of the fact that the disabled person does not have to be transferred into different vehicles for different environments (road, house), this invention provides relief precisely for less strong carers. <IMAGE>

Title: Method for feeding in audible tones and for implementing multiple connections in time division multiplex, digitally through-connecting telecommunications systems, in particular telephone systems
Inventor: WALTER CLAUS DIPL ING
IPC: H04Q11/04
Filed: 1983-04-22
Abstract: The method according to the invention provides that a plurality of mixer devices assigned to the individual connection device groups of a switching system and their associated switching stages are provided which are controlled independently of one another by the group control device responsible. Speech sample words to be processed through addition to form multiple connections are received via the receive busbar arriving from the second switching stage. The summation code words generated within the mixer device are either fed into their own group via the receive busbar leading to the first switching stage or are transmitted via the transmission busbar to the second switching stage. Since a multiplicity of mixer devices are disposed in one switching system and are locally controlled, the central controller is relieved of special tasks involved in setting up multiple connections and has to establish single connections only. Furthermore, an instant substitution or alternative facility is provided in the method according to the invention in case a mixer fault should develop, so that it is virtually impossible for a multiple call not to be set up because of a fault.

Title: Absorption of crude oil resulting from damaged ships or drilling rigs on the water
Inventor: KLAPCZYNSKI PAUL
IPC: E02B15/04
Filed: 1983-08-12
Abstract: My idea is based on the system that light pontoons which are fabricated from steel tubes and are connected to one another are fastened to the port and starboard side of a ship built or converted for this purpose. During slow headway, the pontoons force the leaked oil towards the hull, in which an opening is made on the port and starboard side of the ship, which opening leads into the pump room of the ship, where the oil is filtered and can be stored in tanks. The pontoons can have a diameter of 1.80 to 2.50 metres and a length of 15 to 20 metres. A motor space for an electric motor is incorporated in the forward head end of the pontoons. The electric motor drives a bucket or a conveyor belt to which four to six buckets are attached. The oil is thus forced towards the opening in the hull. One outer float each with a powerful motor is fastened to the outer end of the port and starboard pontoon. The outer floats keep the pontoons on the course of the oil-suction ship. Powerful cable winches are mounted on the port and starboard side at a distance yet to be determined on the top deck of the oil-clearing ship. The cable winches each hold a pontoon on strong steel cables in the desired angular position relative to the oil-clearing ship. According to the state of the sea, height of the swell and the weather, two to four pontoons can be coupled into each other, which on the port side results in two pontoons with outer floats and on the starboard side results in two pontoons with ...
