Patent DE-2843995-A1 (DE)
Title: Solar heat collector sheath - of transparent plastic foil enclosing it and replacing front pane
Inventor: BOETTCHER ALFRED PROF DR
IPC: F24J2/46
Filed: 1978-10-09
Abstract: A flat solar heat collector is entirely encased in a transparent, ultraviolet resistant plastic hose which also takes over the function of the transparent top cover. the hose is welded or bonded tightly on all sides or closed by mechanical means. to achieve adequate mechanical strength and prevent flapping by air movement, the plastic foil should be over 400 m thick (1-2 mm). Any excessive pressure inside the hose by solar irradiation can be eliminated by providing a small aperture which is protected against the ingress or moisture or a plastic expansion bladder with variable volume, joined to the hose volume. This saves the frequent trouble caused by broken front panes, leakage of moisture and condensation on conventional solar heat collectors. The differential thermal elongation of the various collector parts cannot lead to undue mechanical stresses.

Title: Leak detection in ground laid water pipes - uses supply of isolated pipe at increased pressure and monitoring supply and consumption over longer period
Inventor: SAECKLE EUGEN
IPC: F17D5/06
Filed: 1979-02-13
Abstract: The system detects leaks in ground laid water pipes. The process involves recording the pipe pressure over a long period with the pipe (1) isolated from the normal supply and connected via a measurement pipe (10, 11, 24) with measurement elements to a supply. This enables leaks to be found without necessitating long-term interruption of supply to consumers. The pipe is blocked off and bypassed and supplied in isolation at a raised water pressure. If the water consumption in the isolated pipe does not reach a zero over a long period then a leak is indicated. Before the measurement device is switched on pressure varying elements are connected in the measurement pipe. Flow noise variations at the blocking discs caused by leaks in the pipe are measured to indicate the leak(s) positions.

Title: Uniform blown thermoplastic lay-flat tubing - changes plane while passing over guides plus additional reciprocating guide rods
Inventor: SCHWITALLA WILHELM
IPC: B29C48/355
Filed: 1979-07-14
Abstract: Blown thermoplastic film tubing is laid flat and drawn off, using traction rollers and flattening guide plates which reciprocate tog. about the vertical axis of the tubing and where the flat tubing passes from traction rollers over a plane-changing rod at 45 deg. and lying in a fixed vertical plane; the tubing also passes before and later round two reciprocating guides to a fixed vertical guide cylinder; the first guide lies below the plane-changing rod and parallel to the traction rollers, the second guide is vertical and lies between the top of the plane plane-changing rod and the corresp. end of the first guide. Two vertical deflectors are used, the first also reciprocates near the bottom of the plane-changing rod, the second is fixed and is offset from the vertical axis of reciprocation by less than the distance between the rod and the cylindrical guide. The construction is of low cost and permits reverse movement of the flattening plates and reaction rollers through 360 deg. to eliminate formation of varying dia. rings in the reeled tubing.

Title: Differential magnetic field probe adjustment and null monitoring - involves rotating appts. through 180 degrees to exchange sensor positions
Inventor: NISSEN WALTER DR
IPC: G01R33/02
Filed: 1979-07-20
Abstract: An instrument permitting the adjustment condition and null point of a differential magnetic field probe to be monitored uses relatively economical components and achieves the stringent accuracy requirements of ship steering systems operated over long-duration tours. The probe contains two sensors a fixed distance apart. Their outputs are evaluated electronically to determine differential boundary values. The differential probe is constructed so as to be rotatable through 180 degrees and/or to permit a monitor probe to be placed directly adjacent to it while in its operating location. The sensor outputs can be alternately switched to a single measurement amplifier to enable comparison. Rotation brings one sensor to the operating position of the other so that they are both subjected to the same magnetic field.
Patent DE-2930882-A1 (DE)
Title: Automatic telephone branch exchange processor - has store for incoming calls if desired extension is engaged and automatic connection when it becomes free
Inventor: VERHULST FRANS
IPC: H04M3/428
Filed: 1979-07-30
Abstract: In the branch exchange, each extension has two associated memories. If the extension is already enqaged with a call the condition is held in the first memory, and an incoming call is routed to the second memory and held. On completion of the existing call the first memory automatically checks the contents of the second and accepts any waiting call. Once the incoming call is held in the waiting memory, the exchange processor takes no further part in the connection until an instruction to clear the line is received, for example on termination or cancellation of the call. The duties imposed upon the central processor are thus reduced. Typically a waiting signal is given to an incoming call held in the second memory. At the same time an indication is given at the extension that a call is waiting.
