Title: Zig-zag sewing - using eccentric sleeve on shaft of constant speed eccentric drive
IPC: D05B3/02
Filed: 1972-04-17
Abstract: Designed to modify the stitch width in sewing button holes and other looped sewing applications, drive imparts the swing action to the needle, while the driven eccentric sleeve on the drive shaft determines the degree of swing according to a programme related to the time scale of the sewing action. The purpose is to reduce the number and moving mass of control components in executing small stitches at the ends and larger stitches in the centre of the button hole zones.

Patent DE-2251725-A1 (DE)
Title: Welding together high and low-alloyed steels - using niobium-contg low-all-oyed steel barrier to prevent migration of carbon into weld
Inventor: HENNEMANN KLAUS DIPL ING
IPC: B23K35/30
Filed: 1972-10-21
Abstract: Barrier layer consisting of Nb-contg. low-alloyed steel is preliminarily formed on the surface of an unalloyed or low-alloyed steel body, and only then the body is welded to a high-alloyed steel body or surfaced with high alloyed steel. Carbon migration into the weld is suppressed because Nb binds carbon atoms in the barrier layer. Nb can be replaced partly or wholly by other carbice-forming metals such as Ta, Ti, V, W or Mo. This method can be applied to the construction of machines, chemical appts., nuclear installations, etc.

Title: Thermoelectric transducer with ferromagnetic core - has output winding driven thermally into and out of saturation to alter flux
Inventor: BARTELS WILLY
IPC: H01L37/04
Filed: 1973-09-20
Abstract: The thermoelectric transducer is intended to generate directly electric energy from a thermal energy and has a ferromagnetic or paramagnetic core driven thermally in and out of saturation to alter the magnetic flux intersecting a coil wound around it. The core is made from a material whose Curie temperature lies below 200 deg.C, e.g. gadolinium. The temperature fluctuations are kept within a region having a magnetic field of between 5,000 and 50,000 Oe in paramagnetic material, i.e. sufficient to saturate and desaturate the core. The background field necessary to lift the flux towards the aturation region can be produced by a superconducting coil wound around the core.
Patent DE-2362046-A1 (DE)
Title: Safety by-pass in live-steam circuit - from steam generating heat exchanger in nuclear power plant
Inventor: KOLLMAR WALTER DIPL PHYS DR
IPC: F22B37/42
Filed: 1973-12-13
Abstract: The reaction (i.e. the harmful effects) of a break in the live steam pipe of a nuclear power station equipped with a steam-generating heat-exchanger in a coolant circuit is reduced by providing a by-pass between the steam outlet pipe and the water inlet side of the heat exchanger, the by-pass being closed during the normal operation of the power station by means of a valve, which opens automatically if a break occurs. The valve may be operated by a pre-set pressure difference or it may consist of a disc which bursts when a break occurs. The by-pass is pref. located inside the heat exchanger but with the valve being accessible for inspection and replacement if necessary. If a break occurs, the reaction forces on the heat exchanger are thus reduced and a drop in the temp. of the coolant in the primary circuit avoided which is very important in nuclear reactors with a negative coefft. of reactivity.

Title: Mastic asphalt for floors is weigh-batched cold - then heated with sepn. of dust and hot dust finally added
Inventor: KOENITZER KARL HEINZ
IPC: E01C19/05
Filed: 1974-05-16
Abstract: A batch prepn. method for asphalt mixt., esp. for floor surfacing in buildings, is as follows- the graded mineral constituents are cold-weighed and discharged onto a belt, which conveys them to a batch-drier; the burner is ignited and, while the batch is being heated, the dust is abstracted by a blower and sepd. and stored in a bunker; the burner and extract blower are then switched off and, just before the drier is emptied, the stored dust from the bunker is introduced, simultaneously with additional, cold filler, which has been already pre-weighed, to the heated batch and then mixed into the batch until a uniform temp. is reached throughout the mix. Pref., the individual moisture contents of the constituents are measured in the weighing units and are allowed for in the batching operation. All mineral aggregates are wighed cold and moisture content is allowed for. The presence of moisture prevents escape of dust. Since convection from the drier partly preheats the cold filler, the max. temp. in the drier need only be slightly higher than the final temp. Thermal losses due to heating bunkers, elevators, weighers, sieves etc. are eliminated.

Title: Child-proof safety screw cap closure - with radially deformable plastic overcap to grip knurling on screw cap
IPC: B65D50/04
Filed: 1974-06-28
Abstract: A child-proof safety screw cap container closure consists of a knurled screw cap to which a resiliently deformable overcap is rotatably secured by a groove in the overcap engaging round a lip on the mouth of the cap. Radially inward deformation of the overcap causes projections e.g. at two diametrically opposite positions on the overcap, to engage the knurling on the cap so that the latter can be turned. The cap is used generally for containers of medicines, cleaning compounds, insecticides and the like. The closure is simple and cheap to make and is trouble-free in use.

Title: Indirect vehicle fog light - consists of lamp fitted between headlamps throwing light onto concave reflecting surface
Inventor: JUERGENS HERBERT
IPC: B60Q1/20
Filed: 1975-01-18
Abstract: Visibility in fog is better if the wall of fog in front of the vehicle is not illuminated directly and if the driver sees the path on which he is travelling in a less illuminated state than the two sides of the road. The arrangement achieves this by fitting a lamp which is more powerful than the dipped lights. The light (11) is fitted on a supporting structure (14) and, pointing against the direction of travel, throws its light against a concave reflecting surface (10), which then emits an even light in the direction of travel. The lamp (11) is fitted with a blanking-off arrangement as not to inconvenience oncoming traffic. The reflecting surface (10) and lamp (11) are both fitted on the bumper (4).

Title: Magnetic sound record noise reduction method - uses parallel circuits with high and low pass filters
IPC: G11B20/24
Filed: 1975-01-23
Abstract: The noise reduction method in a sound tape recorder uses equalising circuits and filters, together with an automatic volume control system. In the pick-up stage the automatic amplifier control signal goes through a low pass filter tot he mixer. The other component passes through a pre-amplifier a smoother and a modulator (the same signal being injected here), before joining the mixer. The reproducing stage signal is split into a low frequency and a high frequency component, each going through an appropriate filter to the modulator. The high frequency component is demodulated first. The carrier frequency is typically 19.5 khz and the tape speed 19 cm/sec.

Title: Measurement of capacitance and loss factor - using automatic range finding network involving relays and comparators
Inventor: ZINN ERICH DR ING
IPC: G01R27/26
Filed: 1975-02-25
Abstract: The capacitance current is compared with that of a standard capacitance under common applied alternating voltages. The capacitance to be examined is connected in series with a transformer in one of two configurations depending on whether one capacitance terminal is permanently earthed to not. A secondary winding voltage is compared with that produced by the secondary winding of another transformer connected in circuit with the standard capacitance. An automatic range finding network consisting of a set of relays selects the range examined by a complex comparator network. The final output of the network is fed to a calculation network which includes a multiplier stage to produce a voltage proportional to the loss factor. The decimal point on a display is located by the range finding relays.
