Patent DE-3322504-A1 (DE)
Title: Accident prevention device for pedestrian crossings using a flashing light
Inventor: GOTTSCHALK MANFRED
IPC: G08G1/005
Filed: 1983-06-23
Abstract: This is an invention which offers greater safety to the users of pedestrian crossings. A pedestrian does not normally cross the pedestrian crossing until:   a) there is no traffic and he can then cross the road without risk,   b) if there is traffic, only when he has convinced himself that an approaching vehicle is not moving forwards but has stopped in front of the pedestrian crossing in order to allow him to pass.   This vehicle waiting in front of the crossing triggers a contact by means of the induction loop located in the road, as a result of which the connected computer triggers the flashing lights which are installed on the pedestrian crossing. As a result, all the approaching vehicles are warned that pedestrians are crossing. If all the vehicles have begun to move again once all the pedestrians have crossed, the flashing light goes out again after an appropriate time.   In the first case, when there is no traffic and the pedestrians are crossing the road the flashing lights do not come on.

Title: Circuit arrangement for the graduated operation of a discharge lamp
Inventor: HARBRECHT RUDOLF DIPL ING
IPC: H05B41/40
Filed: 1983-07-13
Abstract: A circuit arrangement for the graduated operation of a discharge lamp (2), having a series reactance (3) which can be switched over for different brightness power levels, is intended to be designed for a low circuitry drive complexity with the capability for implementation using light structure - in particular with respect to widespread use, in terms of quantities, for lighting control in the passenger cabins of high-capacity commercial aircraft. For this purpose, the reactance (3) consists of a number of reactance capacitors (12) in a series circuit (11) with in each case one triac (15), which capacitors are connected together with their reference electrode for gate control at a reference potential point (19) for the gate control circuit (10). A capacitive voltage protection circuit (16) is in each case connected in parallel with each triac (15), and hence in series with the reactance capacitors (12); in order to facilitate, on the one hand, DC voltage driving of the triac gate (17) and, on the other hand, in order greatly to increase the reactance of the reactance (3) as a consequence of the capacitor series circuit, so that the discharge lamp (2) can still always be operated at a minimum brightness power level when none of the triacs (15) are switched on at all. At the same time, the control circuit (10) ensures that, in the event of a drive failure, a changeover is made to the minimum reactance of the reactance (3), for panic protection, that is to say the discharge lamp (2) is operated at the maximum brightness power level. <IMAGE>

Title: Training equipment
Inventor: KOELBEL GERT F
IPC: A63B21/068
Filed: 1983-07-20
Abstract: Hitherto, frame-like inclined boards have been used as training equipment for exercises to strengthen the abdominal muscles, accommodation of these boards as home sports equipment having been difficult. The equipment according to the present invention is characterised by a shaped board, which can be put against the fossae of the knees to provide support to the back of the body when the latter assumes a bridge-shaped position with the lower legs at an angle, the part of the shaped board coming to rest against the fossae of the knees being reinforced and having a support surface for the calf muscles which is at an angle relative to the support surface of the shaped board. This permits subframes to achieve an oblique training surface to be omitted. The exercise equipment is thus restricted to an extremely flat, board-like part requiring very little space.
Patent DE-3327336-A1 (DE)
Title: Process for producing waterproof tiles from gypsum, and casting mould
Inventor: QUANTE HEINRICH
IPC: C04B28/14
Filed: 1983-07-29
Abstract: Glazed tiles of gypsum have a considerably greater dimensional stability than those of ceramic or porcelain. They are at the same time rendered waterproof and are provided with the necessary strength factors by producing them from an aqueous suspension of alpha-gypsum hemihydrate, sulphate slag cement and aluminium sulphate and placing them into a tile-shaped mould, whereupon the suspension is defoamed during setting in the mould by vibrations, for example ultrasonically, and then released from the mould after the setting step and, if desired, are also provided with a surface coating. Glazed tiles having optimum strength and good water resistance properties are obtained in particular by introducing the suspension as part charges which have the same or different compositions. The properties relating to water resistance and strength are here particularly good if, in layer-wise production, a mixture of alpha-gypsum hemihydrate and urea/formaldehyde resin and/or melamine resin is introduced into the tensile zone and/or compressive zone of the tile. For implementation, a casting mould is used which is associated with a plurality of mixing vessels, in particular also for the resins and the alpha-gypsum hemihydrate. <IMAGE>

Title: Cutting device for stalks or leaves moved in a conveying channel of a loading truck or the like
Inventor: WEIGL FRANZ ING
IPC: A01D90/04
Filed: 1983-08-30
Abstract: In a cutting device for stalks or leaves which are moved in a conveying channel of a loading truck or the like, knives project, in the working position, into the conveying channel and can be partially pivoted out of this. On the knives engage leaf springs which bend while said knives are pivoting and of which the points of articulation on the knives, on the one hand, and on fixed supports, on the other hand, are arranged in triangular form with the pivot bearings of the knives. To use shorter and weaker leaf springs without any appreciable increase in the technical outlay, a stop (9; 9a; 9b) impeding the free spring bending in one direction is provided for the leaf springs (6, 6') between their points of articulation (7, 8). <IMAGE>
Patent DE-3343083-A1 (DE)
Title: Continuously, vertically adjustable driving (dividable V-belt pulley) and transmission pulley for cycles and machines
Inventor: VIAND ALFRED
IPC: F16H9/10
Filed: 1983-11-29
Abstract: In order to facilitate and better utilise the power transmission in the case of cycles and machines, the driving or transmission pulley is divided into a plurality of semicircular parts. These are secured rotatably in an eccentric manner on a baseplate, thereby making it impossible to fit the parts of the pulley together incorrectly. A ring on which two pins for each part of the pulley are fixed brings about the opening (enlargement or reduction of the diameter) and closure of the pulley. This makes possible an increase or reduction in the rotational speed on a plane with drive and transmission. The parts of the pulley are held fast in the desired position by a single-plate dry clutch, a centrifugal clutch or a Bowden pull. Since the number of parts of the pulley and the diameter can be selected in accordance with requirements, the uses to which the invention can be put are many and various.
Patent DE-3343095-A1 (DE)
Title: Calibrating machine serving to calibrate the inside diameter of rings resistant to high temperatures
Inventor: ZEUGIN HANS
IPC: B23P9/02
Filed: 1983-11-29
Abstract: The calibrating tools are annular segments (18) which can be displaced radially outwards by a truncated pyramid (5) arranged in their centre. An axially displaceable cylinder jacket (24) provided with a heater (23) on the inside is arranged at a distance from the work carrier (14, 15, 16) attached on the outside to the annular segments. Further heating elements (20 and 22) are arranged in a support (12) for the tool carrier (13) and the work carrier as well as in a pressure ring (21) which can be lowered onto the tools. These three parts define an essentially cylindrical space. Each segment is provided with a slider (17) which has two sliding surfaces (17a and 17b), of which one is located in the area of the tools (18) and the second is located outside the heated cylinder space described above, namely in the area of guide slides (8), one each of which is on the one hand firmly connected to the slider (17) and on the other hand can be displaced radially outwards in a guide (7) against the force of a spring (9). In this way, it is possible to allow these second sliding surfaces to slide on cooled mating surfaces (17b). The cooling for this second sliding surface serves to prevent heat from flowing off from the first truncated pyramid (5) to the drive mechanism. <IMAGE>

Title: Bandpass filter for receiving a sound signal transmitted via an electrical power supply network
Inventor: STEINLE BENEDIKT
IPC: H03H17/04
Filed: 1984-05-15
Abstract: The digital part of the bandpass filter consists of the cascade circuit of several part-filters, all of which or a majority of which are second-order IIR filters (7, 8, 10), and contain an FIR filter (10) in one variant, and of an envelope detector (9). At least two of the IIR filters (7, 8) together form a detuning filter. The frequency ranges which are not, or not adequately, filtered out by the detuning filter are filtered out in two variants with the additional IIR and FIR filters. In addition, there is an analog prefilter which filters out the frequency range not yet filtered, nevertheless, and suppresses the mains frequency and strong harmonics of it to such an extent that an inexpensive analog/digital converter is adequate for the digitisation.

Patent DE-3433073-A1 (DE)
Title: Mobile water pump unit with solar cells
Inventor: OLSCHEWSKI JUERGEN
IPC: F04B17/00
Filed: 1984-09-08
Abstract: The problem is that conventional water pump units are tied to a fixed position, owing to the commercial power points, making deployment in different locations impossible. Fields and plantations which are further away can thus not be irrigated, or it is necessary to run pumps having internal-combustion engines. The solution consists in the water pump unit being installed on a mobile carriage, enabling deployment in different locations. Furthermore, the water pump is driven by solar cells, which makes it independent of commercial-type power points. The pump therefore has its own power supply. The mobile water pump unit is used especially for irrigating fields and plantations or for pumping water. <IMAGE>
Patent DE-3440084-A1 (DE)
Title: Brake device, in particular for fluidic working cylinders
Inventor: FREITAG EDGAR
IPC: F15B15/26
Filed: 1984-11-02
Abstract: The invention can be used in the field of high-pressure pneumatics in the pressure range of 0.4-1.5 MPa and wherever sequencies of motion of working cylinders are to be fixed and braked at predefined points. The braking and arresting is to be effected without additional devices at the cylinder in order to ensure that the working cylinder can also be used where the construction space is limited in equipment, machines, automatic machines and manipulating appliances in automation technology. This is achieved by a fluid passing via a channel in a piston rod and/or directly through a bore in the cylinder wall into the hollow space between two or more seals which are arranged one after the other on the piston rod. The admission of fluid to the hollow space can also be effected via a flexible line located in the interior of the cylinder.
