Title: Method of cleaning pipes inserted in the ground during trenchless laying, and device for carrying out this method
Inventor: KOSTYLEV ALEKSANDR D
IPC: E21B7/20
Filed: 1981-01-30
Abstract: Method of cleaning pipes inserted in the ground during trenchless laying, in which method the excavating and receiving of the soil (3) is carried out during the displacement of a working member along the pipe (2) under the action of vibratory impact loads while a foundation layer (7) of soil (3) is simultaneously formed in the pipe, which foundation layer (7) ensures that reactive loads arising during the displacement of the working member are absorbed and changes the direction of the vibratory impact loads in the opposite direction after the soil (6) is received, the foundation layer (7) being removed after all cleaning cycles of the pipe (2) are complete. The device for realising the method contains a working member which is provided with an element for keeping hold of the soil (6) during the excavation and is designed in the form of a capsule (5), the closed end face of which is rigidly connected to a reversible pneumatic punch (4), while the part of the open end face (8) nearest the base of the pipe (2) is constructed with a bevel (9) on the outer surface of the capsule (5). The angle of inclination of the generating line of the bevel (9) relative to the base of the pipe (2) is selected in such a way as to ensure that the foundation layer (7) of soil (3) for absorbing reactive loads during the movement of the capsule (5) is formed during the displacement of the capsule (5) in the base area of the pipe (2). <IMAGE>

Title: Heat exchanger of plate design for internal-combustion engines to be installed, in particular, in lorries/trucks or the like
Inventor: REIMOLD HANS-WERNER
IPC: F28D1/03
Filed: 1981-03-14
Abstract: A heat exchanger of plate design for internal-combustion engines to be installed, in particular, in lorries/trucks or the like has zig-zag lamellae (6, 7) arranged between plates (1a to 1d) and rod-shaped interlayers (2 to 5) which are arranged alternately at in each case two mutually opposite rims of the plates and are flush with the plates, with the exception of parts intended to project. The plates bound flow ducts for crosswise guidance of heat exchanger media of which one is gaseous. In order to settling on the incident-flow side of the heat exchanger which is subjected to the gaseous heat exchanger medium, this side is provided with a plastic coating (12) which has a uniformly smooth surface and which tapers off on the part of the surface directly following the incident-flow side with a slope which opposes flow separation. The plastic coating evens out the roughnesses produced during the production of the parts of the heat exchanger. <IMAGE>

Title: Structure for coves, barrel vaults, spherical vaulting and circular walls in the dry construction method
Inventor: WOERLE WALTHER
IPC: E04C3/40
Filed: 1981-04-06
Abstract: The invention can be used for interior construction work for the purpose of subsequently providing coves, barrel vaults, spherical vaulting or circular walls in rooms. This has been managed hitherto by using the so-called stucco/Rabitz method, a gypsum wet construction method. A structure in the dry construction method, however, offers more advantages since, for example, the parts are easier to mount and the labour outlay is time-intensive overall. The structure for the coves, barrel vaults, spherical vaulting and circular walls comprises a plurality of tube (6) or T-profile arch substructures (3) which are connected by horizontally running transverse connections (5; 1) (e.g. tube profiles, trapezoidal metal sheets). This results in a stable arch form, on which cladding panels (2) are bent in and fastened. The tube or T-profile arch substructures are screwed on wall and ceiling by means of three-dimensionally adjustable securing means (4). (Fig. 1 and Fig. 3) a somewhat more modified construction method makes it possible to achieve regular arch forms by means of bent, flat metal sheets or trapezoidal metal sheets bent towards their profiling. The metal sheets are fastened on at least three longitudinally bracing arrangements. These are screwed on the wall and ceiling and are three-dimensionally adjustable. Cladding panels are bent in onto the metal sheets. <IMAGE>

To compensate for positive or negative temperature coefficients of resistors in the analog signal processing or to generate or to compensate for positive or negative variations of currents with temperature, the high temperature coefficient of integrated resistors is utilised in such a manner that the different emitter resistors generate a positive variation of the collector currents with temperature in one branch and a negative variation of the collector currents with temperature in the other branch. <IMAGE>
Patent DE-3135802-A1 (DE)
Title: Pulse monitoring system
Inventor: TAUS HERBERT G
IPC: A61B5/024
Filed: 1981-09-10
Abstract: An improved pulse frequency monitoring system for determining and representing the heartbeat of a person during the execution of exercises and other activities. The subject-matter of the invention contains a pair of infrared emitters which are set up for positioning on both sides of a thin body appendage, such as the nasal (nose) septum or the upper part of an ear. The light paths of the emitter are modulated by changes in the surface blood quantities in these areas, as a result of which corresponding changes are caused in the output variables of these emitters which are detected by an infrared detector. The powers of the emitters are synchronised in order to output a pulsating (pulsed) receiver output value, which is processed by electronic means in order to supply both analogue and digital representations for the exercising person. The unit further contains a visually perceptible pulse output which blinks on and off at the frequency of the heartbeat of the exerciser. In addition, the unit contains means for setting upper and lower limits which upon being overshot supply a sound signal in order to warn the exerciser in good time so that he corrects his exercise profile.

Title: Electrically screened broadband antenna for the in-phase detection of the magnetic components of an alternating electromagnetic field
Inventor: LINDSAY JAMES E PROF DR
IPC: H01Q7/04
Filed: 1981-10-10
Abstract: The invention relates to a loop or frame antenna having screening against electrical fields. In conventional antennas of this type, the unavoidable switching capacitances in conjunction with the inductance of the loop winding lead to resonances at specific frequencies. The loop antenna described here consists of coaxial line sections in a specific interconnection, in which the inner conductors of the coaxial lines are connected in series but the outer conductors are connected in parallel. In conjunction with a matching receiver input impedance, this construction results in a compensation effect so that, when the alternating magnetic field amplitude is constant, the output signal of the antenna is free of resonances over a wide range, virtually independently of the frequency. Furthermore, the phase difference between the output signal and magnetic field in this frequency range remains low and virtually constant. The antenna can be constructed to be balanced or unbalanced with respect to earth. Areas of use of this broadband antenna - individually or as an antenna array - are, for example, field strength measuring apparatuses, communications apparatuses and direction-finding apparatuses.

Filed: 1982-05-24
Abstract: The invention relates to a lying hollow-cylindrical apparatus for sorption refrigerating installations, in which installation parts belonging to the respective pressure region are arranged in interconnected compartments which are formed by partitions. In order to be able to form the absorber (2) or resorber as a narrow tall tube bank and possibly to accommodate a rectifying arrangement as well as temperature changers and aftercoolers (7), two partitions (4) are according to the invention arranged vertically in such a manner that in the centre a narrow tall compartment and two lateral compartments in the form of vertical segments of a circle are formed (Fig. 1). In the case of the high-pressure part of absorption refrigerating installations, expeller, rectifying arrangement and condenser are arranged in the central compartment, and temperature changers are arranged in the lateral compartments. In the low-pressure apparatus of an absorption refrigerating installation as well as in resorption refrigerating installations, the absorber (2) or a resorber is arranged in the central compartment, and the evaporator (5) or a degasifier is arranged in the lateral compartments. In installations with evaporators lying outside and a refrigerant pump, the lateral compartments are separating and collecting chambers. The invention can be used advantageously even for sorption heat pumps. <IMAGE>

Title: Signalling system for bicycles
Inventor: HAHN FRITZ MANFRED
IPC: B62J6/00
Filed: 1982-06-05
Abstract: The signalling indicator system for bicycles is the ideal solution for reducing the accident rate for bicycle riders in road traffic. Both hands no longer need to be taken off the handlebars since the travel direction is indicated by pressing out the spring-mounted lever with the thumb. By means of the spring-mounted lever, the plastic tube with mount and signalling glass is pressed out and as a result the respective travel direction indicated. The light signal given is also easily recognised from the side and from the rear, for example by car drivers and passengers. The customary holding out of an arm in order to indicate the desired travel direction can be dispensed with. During the journey, both signalling glasses light up at the side without the signalling indicators being actuated.

Title: Passenger vehicle for mining railway trains
Inventor: MEISSEL KLAUS-PETER DR ING
IPC: B61D27/00
Filed: 1982-08-05
Abstract: Passenger vehicle for mining railway trains, in particular for mining railway trains which are operated with a reversible direction of travel. The passenger vehicle has an air changing device which has fresh air inlet openings and air outlet openings. The air changing device is provided with at least one propeller fan which sucks in fresh air and forces it into the passenger vehicle. The air outlet openings are located in the underpressure region of the passenger vehicle body due to ram air. In this way, an intensive exchange of air with an ergonomically pleasant slight overpressure in the interior of the passenger vehicle body is obtained. The drive of the propeller fan can be derived via a gear from a running wheel of the passenger vehicle, the gear being constructed so as to be capable of being shifted or as a rectifier gear in passenger vehicles which are operated with reversible direction of travel. <IMAGE>
Patent DE-3233977-A1 (DE)
Title: Pneumatic operating element
Inventor: HEIMBRODT KLAUS J DIPL ING
IPC: B60H1/00
Filed: 1982-09-14
Abstract: The invention relates to a pneumatic operating element, preferably as a device for central locking systems and butterfly-valve actuation on motor vehicles, with a tub-shaped diaphragm which is firmly and tightly mounted at the margin in a housing and has a diaphragm plate which stiffens the diaphragm in the centre area and is designed to be smaller than the housing. A pivoting movement, i.e. a curved movement, is imposed on the diaphragm plate by an eccentric arrangement of the diaphragm. This takes place by the diaphragm acting as a hinge for the diaphragm plate at the narrowest point between the margin of the diaphragm plate and the diaphragm mounting on the housing side. Coarsely approximated, this diaphragm plate corresponds to the housing contour and it is provided in the area of the centre of force with a piston rod on which the articulation of the part to be adjusted is directly effected. Linkage parts and deflection levers, as are required in pneumatic operating elements acting rectilinearly, can thereby be omitted, which facilitates assembly. The advantages also consist in small overall volume and low weight through the almost exclusive use of plastic parts.
