Title: Lining metal cannulae with PTFE tubing - by stretch-reducing dia. of latter, pushing through, and pulling at other end until lined with unstretched section
Inventor: MUTH HUBERT
IPC: F16L47/28
Filed: 1978-05-30
Abstract: Metal hollow needles, tubes, and similar small-dia. articles are lined with chemically inert plastics by stretching the end section of a plastics e.g. PTFE tube whose outer dia. is equal to, or greater than, the inner dia. of the article to be lined, in such a way that the outer dia. of that end section is reduced, over a length slightly more than the length of the metal article, to less than the inner dia. of the latter. The thus-reduced section is pushed completely through the metal needle etc. until it emerges at the other side, and then pulled until the metal needle etc. is lined over its whole length with plastics tubing that has not been reduced in dia. Excess tubing protruding at either end is then cut off. Also claimed is a similar process for fixing tubular connection in apertures, eyelets etc. esp. in laboratory appts. e.g. electrophoresis instruments, where the above-described procedure is allowed to a point where the non-reduced tubing is pulled or pushed through an aperture until it wedges itself tight in the opening. Any excess is opt. snipped off. Such plastics e.g. PTFE tubing may be used for sheating metal needles etc. by pushing it into the plastics tubing; heating; and thereby shrinking the sheathing tightly over the protruding ends of a previously fitted lining. In this way, metal needles and similar small-dia. tubes are obtd. that are both (e.g. PTFE-) lined and coated.

Title: Coordinate converter for multichannel directional receiver - has matched distance and direction signal paths and includes ADCOCK antennae
Inventor: FLIEGE HANS-JOACHIM DIPL ING
IPC: G01S3/32
Filed: 1978-11-14
Abstract: A coordinate converter connects an Adcock antenna system to a multiple channel directional receiver such that the individual antenna voltages are combined into two directional and one distance voltages via power dividing and summing circuits. It avoids the complicated compensation circuits conventionally required because of the phase variation between the directional voltages and the distance voltage caused by frequency dependent and differing complex internal resistances. The signal paths used to form the directional and distance voltages are constructed identically w.r.t. the switching elements affecting the complex internal resistances by virtue of their operating modes. They are constructed identically w.r.t. the switching elements affecting the internal resistances because of the signal transport time or each path has switching elements which affect the transport time equally.

Title: Cooling circuit for mine air - provides initial waste heat transfer to pit water through heat conductor circuit
IPC: E21F3/00
Filed: 1979-01-30
Abstract: Waste heat produced in low-temp. generation is carried away above ground via a heat-conducting medium, for cooling the atmosphere in underground mines. Waste heat is transferred to the pit water by a heat-conductor circuit and then carried up to the area above ground. The heat-exchanger can be a set of thin-walled hollow plates close together, with hollow space serving for heat-conductor passage. Pumps may be allotted to individual sets. This enables large quantities of waste heat to be discharged without additional loading on the shaft.

Title: Double knitted or woven fabric cutter - has a sawtooth cutting blade to separate fabric layers
Inventor: GOEBBELS WOLFGANG
IPC: D03D39/18
Filed: 1979-02-16
Abstract: To separate two woven or knitted fabric layers, there is a divided cutting blade which moves parallel to the wefts or rows of stitches. This ranges over the whole width of the fabric and has a sawtooth profile in a row towards the double fabric. The blade slides on a guide running parallel to the line of weft insertion or the rows of knitted stitches, and is connected to a drive by at least one rod. The drive rods are linked to the cutting blade and a crank, and their length can be changed. A piston cylinder assembly is integrated into the rod structure, so that the end of one rod is connected to the cylinder, and the end of the other rod joins the piston while a pressure source is provided for the cylinder. The design reduces the load on the cutting surfaces, and reduces the risk of cutting marks on the fabric.

Title: Control circuit for electric storage heater - prevents unwanted charging with low outside temps. lying outside switching characteristics
Inventor: ALBRECHT ROBERT
IPC: G05D23/24
Filed: 1979-03-01
Abstract: The control circuit has a charging limiting signal (E3, E4) adjustable between two reference voltages (OV and -5V). The upper (Eo) and the lower (Eu) levels of the control signal (U2) pass through a voltage equal to one of the reference voltages. A voltage limiter (3) limits the control signal below the lower level to the first ref. voltage (OV). An adder (5) connected to the limiter's output processes the charging limiting signal and the control signal. A comparator (7) coupled to the output of the adder compares the adder's output with the first ref. voltage to generate a release or disable signal. The voltage limiter is an operational amplifier with a diode connecting its output to its inverting input, which is also coupled via a resistor to the first ref. voltage. The release signal initiates the charging of the storage heater but does not appear if the low outside temp. lies outside the transfer characteristics.

Title: Digital transmission system for analog signals in audio studios - employs a=d and d=a converters using linear interpolation (OE 15.8.79)
Inventor: KRAKER ALFRED ING
IPC: H04B14/04
Filed: 1979-04-25
Abstract: The digital transmission system employs simplified and highly precise A/D and D/A converters for the audio signals. These converters use linear interpolation. The analog input signal (x) passes via an amplifier (VI) to the A/D converter (A-D) and via a discriminator (D1) to a store (SPI). A summation circuit (SM) adds the store output to the A/D converter output to form the digital transmission signal (y). At the receiver the digital signal passes via a second discriminator (D2) to a second store (SP2). A subtractor (DF) subtracts the store output from the received digital signal and passes the difference to the D/A converter (D-A).
