Title: Flexible steel barrier for roads and motorways - consists of two-sectional uprights with safety screws with single or double steel horizontal bar
Inventor: POHL MAX
IPC: E01F15/04
Filed: 1973-12-15
Abstract: The horizontal bar is screwed to a readily deformable support made of low strength flat steel, which is welded to a rectangular of similar-shaped spacer piece made of high strength flat steel. The horizontal bar, together with the support and spacer-piece is fixed to one side of a I-shaped upright by means of a strong screw. The other side of the I-shaped upright holds an identically constructed bar. The upright is in two parts, with a steel plate welded to each of the sectional points. Each steel plate is screwed to the other to make one upright which is rammed into the ground. On impact, the two screws break, with the top upright half remaining upright.

Title: Radio receiver with digital frequency display - oscillations of AM or FM oscillator are counted during certain time interval
Inventor: KLANK OTTO
IPC: H03J1/04
Filed: 1973-12-18
Abstract: The electronic counter is used for amplitude or frequency modulated oscillations, differing from the received oscillation by the number of intermediate frequency oscillations. The counting is done periodically and in order to subtract the intermediate frequency, the counter is at the beginning of counting delayed by a time corresponding to the respective intermediate frequency. An additional counter counts the number of oscillations corresponding to the intermediate frequency and when this number is reached, it starts the new counting cycle by the main electronic counter. During the additional counter operation it may have its period extended, to correspond to the intermediate frequency time duration.
Patent DE-2363751-A1 (DE)
Title: Swimming-pool water circulation and filtering plant - reversing circulation when non-operational with withdrawal through bottom openings
Inventor: REICHLING OTTO DIPL ING
IPC: E04H4/12
Filed: 1973-12-21
Abstract: The purpose is to ensure removal of solids sinking to the bottom without employing special suction apparatus, in a system where water is constantly circulated via a filtering plant, preceded by a swell-water container for displaced water, with filtered water flowing into the pool, while the bath is in use, through a series of openings distributed over the whole bottom of the pool. When the pool is not in use the circulation system is reversed, so that the circulating water is withdrawn through these openings, and carried back to the pool after flowing through the filtering plant. Thorough cleaning of the pool bottom is simplified.

Title: Hand operating lever for multi way spool valve - is linked to spool at right angle by plastic elements
Inventor: STUERMER JOSEF
IPC: F16K31/60
Filed: 1974-03-02
Abstract: The operating lever of a hand operated valve is attached to one end of the valve body at right angles to the valve spool. The lever is anchored in a transverse shaft which acts as a pivot and linkage between the lever and a axial extension of the spool shaft. A shoulder pin produces a floating connection between the spool and its extension, thus eliminating the effects of any misalignment. A spring loaded ball, located inside the transverse shaft engages in appropriate recesses so that different valve spool positions are distinctly recognised. The transverse shaft and the body which attaches the operating elements to the valve are made from plastic.

Title: Automated system for fitting cable sleeves - combines centring, stripping sorting sleeves conveying by air current and crimping
Inventor: SCHNEIDER HEINZ-ERICH
IPC: H01R43/04
Filed: 1974-03-09
Abstract: The system fits cable sleeves which comply with DIN 46228 as prescribed for plug and clamp joints of type FLK DIN 72551.

Title: Mixing and injecting plastics, esp polyurethane into a mould - with sudden applied suction to prevent follow-up injection
IPC: B29B7/58
Filed: 1974-04-25
Abstract: A method of cyclically injecting or casting flowable plastics, esp. polyurethane, into moulds is carried out using a casting head comprising a mixing chamber, into which the separate components are supplied in sufficient quantity for one cycle; after injection has been completed, the feed of components is cut off and a partial vacuum is immediately created in the mixing chamber, esp. by increasing the volume of this chamber, to prevent a further flow of undesired material into the mould. a positive cut-off of feed of mixture into the mould is ensured by the sudden increase in size of the mixing chamber and consequent reduction in pressure.

Title: Polyurethane foam block of rectangular section - produced by pressing non-porous cover sheet flat onto expanding foam
Inventor: CARPIO BERNARDO DEL
IPC: B29C44/30
Filed: 1974-08-08
Abstract: An appts. for producing continuous, flat, rectangular-section blocks of polyurethane foam comprises a moving floor or belt and also side walls, onto and between which the material is foamed with the intermediary of a lining sheet to the bottom and walls of the mould. In addn., a device supplies a non-porous covering sheet to constitute a fourth wall of the liner; at the initial foaming position a number of transversely rigid pivoting elements are mounted upon independent frames and extend transversely across the top of the foam to regulate its expansion; these transverse rigid elements, such as rolls or flat sliding plates, ensure that every point of the upper surface of the foam is guided. Adjustment devices enable the pressure exerted by these transverse rolls to be varied, the distance between the pivoting axis and the surface remaining however constant. Where expansion of the foam has ceased, heaters bond the top covering sheet to the foam and, downstream of this, a piercing device comprising needles or spikes forms apertures in the top covering sheet.

Title: Six-phase stator winding for turbo generator - has windings of two three-phase systems wound in different senses to to raise voltage rating
Inventor: CHUTORETSKIJ GARRI MICHAILOWIT
IPC: H02K3/28
Filed: 1975-04-28
Abstract: The six-phase stator winding, for a turbogenerator (1200MW), is designed and wound to give a lower maximum voltage between winding bars in the overhang. To achieve this the 3-phase windings comprising the 6-phase system are wound with different winding senses, i.e. one 3-phase winding phase is laid to the right, and the next corresponding phase of the other 3-phase system is laid to the left, and so on. The connections to these 3-phase windings are made at different places on the stator. This arrangement effectively excludes corona discharges at the generator's highest rated voltage and thereby allows the voltage rating to be increased.
