Patent DE-2143225-A1 (DE)
Title: Edge knitting - on fibre or strip base for attachment to the garment
Inventor: ARNDT WERNER
IPC: D04B1/24
Filed: 1971-08-28
Abstract: The knitting sequence is started by a row system stitch followed by alternate rows of round stitches with the forward and rear needle bed until the edge is knitted. Separating zones are created by the use of smooth solid yarns which can be dissolved, in contrast to the fine yarn used in the knitting process. The purpose is to provide an edge which can be attached to knitted or woven fabrics, non-wovens or leather by sewing, adhesion or heat fixing.

Title: Saw tooth hardening - by grinding process
Inventor: IDEL WLADIMIR W
IPC: B23D63/20
Filed: 1972-08-31
Abstract: The teeth of saw blades which have previously been conventionally hardened to 52 RC are further hardened to 65 RC by grinding with a grinding disc, which causes the front and rear edges and the cutting edges of each tooth to heat up to near the melting temp. of the blade material, from which temp. it is quenched to the tempering temp. by the air stream formed by the rotating grinding disc following which it is allowed to cool slowly to room temp. The method requires no special additional equipment and yields uniform results.

Title: DC arc welder unit - with constant power regulation using variable firing angle control stages
Inventor: NAGASAKA MORITOSHI
IPC: H02M7/162
Filed: 1973-07-31

Title: Pressure variation indicator for mounted tyres - has non-magnetic cylinder with permanent magnet and two magnetizeable elements
Inventor: PAVLIC RUDI
IPC: G01L19/08
Filed: 1973-10-12
Abstract: A cylinder of non-magnetic material is fastened to a part in turn connected to the rotating tyre. The cylinder interior is in contact with the tyre interior, and contains a permanent magnet and two magnetisable parts, displaceable relative to one another, dependent upon pressure variations in the tyre. In a bridging position, the two parts form a closed magnetic circuit for the reflux of the magnet. In an intermediate position, the circuit is interrupted, and a stray outlet for the magnetic flux out of the cylinder is possible. A stationary part of the vehicle carries a contact switch in an electric circuit, transmitting a signal, when a pressure variation is present. The switch is located within the stray range, relative to the cylinder.

Title: Radar system location accuracy improvement - is by increasing azimuth resolution in passively reflecting targets
Inventor: SPECKTER HANS E DR ING
IPC: G01S7/292
Filed: 1974-03-13
Abstract: To reduce the gain dependent on the maximum signal amplitude of the target or to emphasise the detection threshold in the immediate range of the target, there is intermediate storage of received signal trains of several radar periods within a narrow azimuth interval, rotating with the aerial, of the width of the aerial lobe, followed by the signal maximum in this interval being determined independently for each radial quantisation step or range circle. According to the amplitude of this signal maximum, the gain of the signal taken from the middle of the interval and not erased in the store is reduced and the detection threshold emphasised so that this threshold intersects the aerial lobe in the top narrow part.

Title: Grinding and polishing small glass lenses - uses disc and three lenses pressed integrally and attached to backing disc
Inventor: HAUSER HANS
IPC: B24B13/00
Filed: 1974-04-18

Title: Cct. for temporary change of DC supply - designed for calling or signal line supplied from scanned DC converter
Inventor: LAMMERT ULLRICH ING GRAD
IPC: G08B29/06
Filed: 1974-07-06
Abstract: The voltage output value of the scanner is determined by either the signal condition of the supplied calling or signal line or a criterium which can be taken from the caller. The scanner (T) controls two switching-over contacts (K1 & K2). These contacts reverse two working lines each having a storing capacitor (C1 & C2). The rectifiers (G11 & G21) charge the capacitors, while the other rectifiers (G12 & G22) discharge them. These rectifiers in combination with the bridging rectifier (G3) determine the blocking conditions in accordance with the voltage relationships. The pertaining charging current is limited by either of the resistors (R1 & R2) in the charging circuit. The capacitor (C3) smooths the discharge current.

Title: Intrinsically safe control of electric switchgear - is through a control line supplied with AC near the switch with a terminal rectifier
Inventor: TRIESCH WOLFGANG
IPC: H03K17/68
Filed: 1974-08-30
Abstract: The control line is terminated by the rectifier when a key is operated, and the switch responds to the direct current flowing through the line and carries out the required switching operation. A controllable rectifier control input is connected to bistable switching means outputs which signal the switch state. The switches are supplied in parallel with the rectifier through the control line, and when a push-button switch is operated, the bistable switch state is changed. The alternating current component (StL) has a half cycle short-circuited by one diode (5) in parallel with a smoothing capacitor (7), which smooths out the half-wave passed through a second diode (6) in parallel with the line.
