Patent DE-2328111-A1 (DE)
Title: Continuous wire straightening machine - having one adjustable eccentric roller in revolving straightening frame
Inventor: LINDEMANN HANS
IPC: B21F1/02
Filed: 1973-06-01
Abstract: A straightening machine for wire consists of a revolving straightening frame between pairs of input and output rollers which prevent the moving wire from revolving. The straightening frame contains only one eccentric roller at a slight angle to the centre line and is rotated at a much higher speed than conventional straightening machines. The eccentricity of this roller and the distances from input and output rollers to the frame are adjustable. The setting times and the times for converting to other wire dias. are thereby reduced to a minimum. The machine design is simplified and the desired straightening result is ensured without having to employ highly skilled labour.

Title: Disposable paper cup for hot drinks - has an insulating outer sleeve or carrying flange
IPC: B65D25/22
Filed: 1973-06-16
Abstract: The design is intended to replace plastic material with paper to reduce environment pollution. The moisture-proof cup is fitted with an outer layer of dimpled and perforated paper. The dimples, approximately 3 per cm2, project inwards and maintain an air space of paper thickness. An alternative form uses a lid which keeps the cup clean before use and which has a pull-out centre so that the lid can be slipped over the slightly conical cup from below to form a carrying flange half way up, which has insulating characteristics.
Patent DE-2336975-A1 (DE)
Title: Grain discharge system for tipper vehicles - has counter screw conveyor near discharge opening to partly unload before tipping vehicle
Inventor: DOVE HEINRICH
IPC: B60P1/40
Filed: 1973-07-20
Abstract: A complete mechanical discharge of the load is achieved by providing an endless screw conveyor parallel to the tipping axis close to the sideboard discharge opening and extending the whole length of the vehicle. The screws run counter to each other with a space opposite the discharge opening. The screw shaft runs in bearings located in the front and rear end walls. The front screw carries a drive coupling, and a protective grid covers the conveyor. In order that the grain is not crushed the screw thread is formed as a tube and the thread axial spacing is a multiple of the thread height.
Patent DE-2338724-A1 (DE)
Title: Aircraft navigation system - uses two dipoles and sample amplitude modulated signals for horizontal flight path identification
Inventor: ZETZMANN HANS JOACHIM DR ING
IPC: G01S1/02
Filed: 1973-07-31
Abstract: A system for allowing flight path identification in the horizontal plane near small airfields, by radio signal. The principle of this system has already been applied to flight path identification in the vertical plane and consists of two co-linear dipoles mounted horizontally each of which transmits two signals modulated at, for example, 150Hz and 90Hz. The phase and amplitude of these signals are equal at the dipoles, and by observing the phase and amplitude differences as received by an approaching aircraft, the equipment in the aircraft is in principle able to deduce the flight path relative to the axis of, say a landing strip on which the dipoles are suitably disposed. The system is simple and operates symmetrically to deal with both approach paths to a landing strip, and the system is largely independent of the carrier frequency, so that any future change in this by international agreement would be easily accommodated.
Patent DE-2348346-A1 (DE)
Title: Safety members for roller blind profile bars - prevent side movement by fitting in slit in bar and moving freely in hinge
Inventor: HARDT WALTER

Abstract: Safety members for preventing side movement are applied to roller blind profile bars. A post is formed by at least three bars laid close together on a working table connected by hinge edges and the bars have slits and safety members attached. The slits are produced simultaneously on two adjacent bars by cutters on a common lowerable mechanism. One end of the member is fixed to a bar and the other moves in the hinge edge. The safety member surface is provided with teeth which permit free movement in the hinge edge but prevent falling out.

Title: Fencing training reaction time measuring device - signals when hit is made and counts number of hits
Inventor: PLACHUTTA EGON
IPC: A63B69/02
Filed: 1973-11-07
Abstract: The device is mounted on a wall and consists of a panel supporting five signal lamps covered by sheets of perforated metal. The signal lamps are switched on in a sequence unknown to the fencer who thrusts at a perforated plate as soon as the lamp behind it is illuminated. If a hit is achieved it is signalled by a lamp mounted above the main panel. The number of hits is also recorded by the counter and the reaction time, that is the interval between the lighting up of one of the lamps and the fencer making contact with its covering perforated plate. The duration of illumination of the lamps is controlled by the switch.

Title: Concrete structure form attachment-block system - has plastic triangular shaped units for preliminary outline rationalisation and delineation
Inventor: HUEBNER WALTER
IPC: E04G17/14

Title: Electrical contacts mfr from silver-metal oxide powder - by pressing to obtain very low porosity, thus reducing burn-off
Inventor: SCHREINER HORST PROF DR
IPC: B22F3/16
Filed: 1974-07-31
Abstract: Process is for the power-metallurgical prodn. of shaped pressings with residual porosity below 1% and uniform pore distribution, using a dispersion-hardened silver-metal oxide composite powder, for electrical contacts. The composite powder is first compacted to form a blank (I), which is then hot-pressed to form an intermediate blank (II) which its surface area increased by 5-15%. and (II) is cold-pressed to the final shape with an increase in surface area of 2-8 %. (I) is pref. sintered before hot-pressing and (II) is pref. sintered in an inert atmos. before cold pressing. The pref. device is a press with hot- and cold- pressing positions and automatic pushers moving the compact, plus shears for final removal of flash. The burn-off during arcing of the contacts is greatly increased due to the existence of porosity; this process reduces the porosity, thereby reducing burn-off by e.g. 40% cf. conventional contacts.

Title: Indexing system for microfilm strip - with main store for group addressed and sub-store for frame addresses
Inventor: BICKL HORST DIPL PHYS DR
IPC: G06K17/00
Filed: 1974-10-12
Abstract: The microfilm, or similar record, is indexed with frame markings for easy identification by a central control. The indexes are divided into sub-groups, with the first frame of each group identified and marked. A second set of indexing markings is provided on another position on the record and identifies the separate frames in each subgroup. For rapid identification and retrieval of any particular frame the index contains the subgroup and frame information. For rapid search the first frames of each subgroup are scanned until the relevant subgroup is found, after which the frame is identified.

Title: Turbine blade erosion prevention - by addition of metered amounts of octodecylamine and morpholine
Inventor: CZEMPIK ERWIN DIPL ING
IPC: G21D1/00
Filed: 1974-10-23
Abstract: Erosion of wet steam turbine blades used in nuclear power stations with pressurized water reactors or in conventional power stations can be reduced by adding to the secondary circuit film-forming amines alone and/or volatile alkalization agents. The former is preferably octadecylamine and the latter morpholine, the concentration being up to 30 mg per litre. This system requires little extra expenditure and no radial constructional alterations to achieve the desired reduction of blade erosion. The fine droplet spectrum prevents the formation of water films.

Title: Ultrasonic underwater echo sounding equipment - is especially for fishing boats and has suppression of double echos without need for recording delay
Inventor: CAUER ROBERT
IPC: G01S15/10
Filed: 1975-03-03
Abstract: The echo soundings are carreid out alternately at one of two different frequencies and the echo signals at both frequencies are selectively amplified. The frequencies are pref. selected so that one is 30kHz plus 0.5 - 1 KHz. A receiver has a single-channel amplifier (2) with a switch (10) which operates in synchronism with the alternation of frequency to tune the selection devices (3, 12) to the appropriate frequency. The selection devices make the amplifier insensitive to the frequency of any double echo from the previous sounding cycle.
