Title: Composite pipe esp. for building drainage - has plastics tube helically wound and bonded intermediate layer and metal outer sheath with longitudinal seam
Inventor: VOSS PETER DR ING
IPC: B29C48/151
Filed: 1980-06-21
Abstract: Composite pipe, esp. for plumbing and more specifically for drainage purposes, comprises an internal plastics tube, intermediate layer, and metal outer layer or sheath produced from a long strip folded around the intermediate layer at a distance from it, closed at the longitudinal seam and subsequently mechanically compressed to press it onto the intermediate layer. The intermediate layer (2) is formed by helically winding onto the plastics tube a metal band coated on both faces with an adhesive appropriate for bonding to the inner and outer pipes respectively. Used for drainage pipes in buildings, where the interior of the pipe must be resistant to aggressive media and the exterior of the pipe must be fire-resistant. A secure, intimate bond between the three layers is assured; risk of hydrogen or oxygen diffusion causing deterioration of the composite pipe is eliminated.

Title: Safety system for steam or gas turbines - uses combined hydraulic and electrical system with pressure switches and magnetic valves
Inventor: KUEHNLEIN KLAUS ING GRAD
IPC: G08B23/00
Filed: 1980-10-25
Abstract: The safety circuit consists of hydraulic pressure switches (4,5,6) operating electrical switches (4',5',6'), magnetic valves (1,2,3) and membrane sealed pistons (7,8,9). In one condition, a state of readiness exists at all three channels (I,II,III), as all three coils (1,2,3) of the magnetic valves have pulled on and released the fluid pressure on the upper side of the pistons (7,8,9). The pipe pressure (11) corresponds to the flow pressure at the inlet (10), and the pressure fluid now holds the connected element at the pressure connection (19) open, for example in the case of a turbine fast-close valve. As the pressure switches (4,5,6) are actuated on by the release of pressure through the three magnetic valves (1,2,3), and the first set of changeover switches (4',5',6') are activated, at the same time, the second set of changeover switches operate (13,14,15), and no current flows to the channel disturbance indicators (lamps).

Title: Automatic alarm signalling of sub-stations in primary stations with DTMF signal transmission
Inventor: KOEPSEL MANFRED
IPC: H04Q3/62
Filed: 1982-02-10
Abstract: The invention relates to telecommunications systems with at least one primary station and one or more sub-stations, where fault occurrences in the sub-stations are automatically transmitted to the primary stations. The sub-stations (UA) transmit an occupancy criterion in the form of a pulse signal via sub-station transmission devices (UA-UE...) as alarm signallings and a switching function criterion as a DTMF secondary identification code, which criteria specifically control signalling means (AI, KL) in the primary station transmission devices (HA-UE...). Telecommunications systems of this type are used in particular in dedicated telephone networks. <IMAGE>
Patent DE-3204687-A1 (DE)
Title: Gearing arrangement
Inventor: SCHEUERPFLUG HANS
IPC: F16H15/10
Filed: 1982-02-11
Abstract: The invention proposes a gearing arrangement (10), in particular for the motor-driving of cable drums. Gearing arrangements with mechanical gearwheel or chain drives or combinations of the latter are known. For different application requirements, the transmission ratio of the gearing arrangement, the motors to be provided etc. must each be matched individually. In order to achieve the necessary transmission ratios, a multiplicity of transmission elements are necessary. To overcome the said problems, the invention proposes a special arrangement of a friction wheel gearing (28, 30, 30a, 30b) of compact construction with a faceplate (30, 30a, 30b) arranged coaxially to a main shaft (14) and displaceable elastically in the axial direction and with a friction roller (28) which drives the said plate. On the basis of this principle, the transmission ratio is first of all easy to adjust in adaptation to the requirements which arise. The transmission ratio can be altered during operation. Easy adaptation to requirements which arise, in particular as regards the torque to be transmitted, is possible by the provision of additional drives in a modular form. <IMAGE>

Title: Control arrangement for furnace systems in steam or heating boilers
Inventor: TAMURA MASATOSHI
IPC: F23N3/08
Filed: 1982-04-22
Abstract: Control arrangement for furnace systems in steam or heating boilers, particularly in boilers of the packaged-boiler type, with speed-controlled combustion air blowers, in which, depending on a load signal as first controlled variable, the fuel and the combustion air feed are at the same time adjusted at a particular ratio with respect to one another by a combined actuator, a controlling element controlling the speed of the blower drive motor being provided and a gas density measuring element, particularly an O2 gas density measuring element, supplies a second controlled variable for finely adjusting the speed of the blower drive motor by controlling the said controlling element. The novel feature is that a steady load-dependent speed curve is stored as reference value in a function generator (204) which forwards a first output speed signal (X1), corresponding to the respective load state, as first input variable to a control element (205), that the control element (205) is supplied with the output signal (DV) of a comparator (203), particularly after signal processing via a PID element (202), as second input variable (X2), the comparator (203) being supplied with, on the one hand, the measurement value (PV) of the gas density measuring element (19) and, on the other hand, the output variable (SV) of another function generator (201) in which the gas density is stored as a load-dependent setpoint curve; and that after processing of the first and second input variable, the resultant output variable (X3) is supplied to the controlling element by the control element (205). <IMAGE>

Title: Method for determining the charge state of electrical accumulators
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: G01R31/36
Filed: 1982-05-03
Abstract: The actual charge state of accumulators having an electrolyte which takes part in the electrochemical conversion (e.g. a lead-acid accumulator) is determined in that the charge taken up to a specific point in time from the accumulator having the useful capacity (KN) is measured both in terms of electron charge levels (= KC) as well as via the change in the electrolyte density (KD). The weakening of the electrolyte in the plate pores results in a difference KC-KD =  DELTA K. The residual charge (KR) which is in reality still available - the current charge state - follows from the relationship KR = KN-KC- alpha  DELTA K, in which the proportionality constant  alpha , which is a function of the structure, has a value between 1 and 1.2. The charge values corresponding to the charges KC and KD removed and the current charge value KR corresponding to these values can be signalled on a three-row scale by means of measuring marks (1, 2, 3).   <IMAGE>

Title: Tyres for vehicles, in particular for bicycles
Inventor: KOMANDER HEINZ
IPC: B60C7/14
Filed: 1982-08-19
Abstract: Tyres for vehicles, in particular for bicycles, are generally composed of an outer cover and an inner tube covered by the latter. In order to create a tyre which does not need to be supplied with compressed air and remains fully functional in the event of minor damage, such as the penetration of nails, sharp stones or the like, it is proposed that the tube be formed from a flexible plastic tube which on the outer circumference has all-round ribs which are dimensionally stable and dimensioned such that a customary load-bearing capacity results.
Patent DE-3231327-A1 (DE)
Title: Shock absorber for loads transported in vehicles
Inventor: SCHOENBERGER PETER
IPC: B61D45/00
Filed: 1982-08-23
Abstract: In a rail-bound goods waggon, the load to be transported is separated into individual stacks of material for loading by means of separating walls, the separating walls being locked in longitudinally displaceable rails, with spring suspension by means of shock absorbers, in goods waggons, and the load forming the loading unit is displaceably damped in both directions of movement. An impact on the goods waggon is thus transmitted to an end wall, damped by the entire loading unit. By means of the design of the rails according to the invention and the resulting division of the load into at least two loading units and the special grip of the rails on the shock absorbers, the material for loading and the end wall are to be protected. This is achieved in that each longitudinal side of the vehicle has in the floor and on the roof two locking rails which are constructed in a similar manner, aligned axially with respect to one another and located at a distance from one another, the two locking rails on each side of the vehicle being coupled to the shock absorber in each case via a movable lever linkage.
