Patent DE-2925181-A1 (DE)
Title: Contact bar for vehicle parking collision prevention - has deformable fluid container or electromechanical transducers connected to e.g. dashboard indicator
IPC: B60R19/48
Filed: 1979-06-22
Abstract: The contact bar, esp. for use on vehicles or on objects endangered by vehicles being parked, can also be mounted on a vehicle or on an obstacle. It indicates to the driver of the vehicle that it is close to or touching an obstacle. The contact bar is elastically deformable and takes the form of a bumper mounting or part of a trim strip with a sensor over the whole length. Deformation causes an optical and/or acoustic signal to be generated inside the vehicle. A hermetically sealed fluid container attached to the contact bar is connected to the indicator unit via a tube. The deformation of the bar causes a pressure variation in the fluid which is converted into an indication signal. Alternatively, mechanical electrical pressure transducers may be used.

Title: Laboratory extraction and separation flask - being flat bottomed conical flask with side branch for venting and with run=off cock attached on the top
Inventor: LUDWIG HEINZ
IPC: B01L3/00
Filed: 1979-06-30
Abstract: Sepn. flask is a flat bottomed conical flask with a side branch close to its base which can be shut off. The conical apex of the flask has a further outlet to which is attached a cock. Cock has a projecting arm above its outlet which traps a magnetic stirrer element if this is used in the flask and prevents it from blocking the outlet. The contents can be mixed and heated with the flask placed on a hotplate etc. To separate two phases, the flask is inverted and the two layers run off. Used for carrying out extraction experiments in the laboratory. Allows two liq. phases to be mixed and treated without the need for manual or machine shaking. Any overpressure developing can be safely vented without loss of solute and the contents can be heated during the extraction experiment.

Title: Welding machine for mfg. box grids for concrete reinforcement - where spot welds are made between longitudinal, zigzag, and transverse rods in automatic sequence
Inventor: VOLKOV SERGEJ NIKOLAJEVITSCH
IPC: B21F27/20
Filed: 1979-07-13
Abstract: A top(42)-, middle(43)- and bottom(41)- longitudinal rod are fed through a row of three welding stations(33,7,14); and stations (7,14) are each mounted on a reciprocating slide. In station(33), alternate transverse rods(44a) are spot welded to the lowest rod (41) to make a bottom grid. Rod(43) is bent in a zig-zag pattern so it can be alternately spot welded to rods(4l,42); and alternate transverse rods(44b) are spot welded to the upper rod(42). The overall result is the mass prodn. of a rigid box grid or girder. Automatic mfr. eliminates manual work and manual welding.

Title: Tube guide system for underfloor heating - uses plates with cross channels and straight channels and pattern of guides for bends
Inventor: PROBST DIETRICH
IPC: F24S10/75
Filed: 1979-08-10
Abstract: The under floor heating system which uses plates (1) which fit together along joint lines (17) to guide the heating tubes (6,7) has parallel grooves to retain the straight parts of the tubes. At the ends of these grooves are blocks (14) with a pattern of guides (15) for the bends at the ends of the tubes. Across the outer parts of these blocks is a channel (11) at right angles to the straight grooves to hold connecting elements. The sides (12) of these grooves have regular gaps (13) through them. The guides include oval shaped raised parts, one opposite each channel, with pointed intermediate parts between, front and rear. The arrangement allows different numbers of the channels to be occupied by tubes, to suit the heating requirements of the installation.

Title: Display shelving with rear vertical support panel - has forwardly inclined transparent supports with goods accommodated behind it
Inventor: JOOS GOTTFRIED
IPC: A47F7/14
Filed: 1979-09-03
Abstract: The shelves which are fixed to the console brackets attached to the rear upright have a bearing face (4), inclined to the vertical or pref. transparent, and a support face (3) which is set at the lower edge of the bearing face on the side of same remote from the customer.

Title: Airscrew shroud doubling as radiator - is hollow and is carried on hollow struts acting as engine coolant supply and return lines
Inventor: BERCHTOLD GERD DIPL ING
IPC: B64D33/10
Filed: 1979-09-10
Abstract: The airscrew shroud doubling as a radiator is conventional in basic shape and profile.

Title: Voltage stabilising and smoothing reactor - comprises core with air gap and capacitor in parallel with winding
Inventor: WEBER ULRICH
IPC: G05F3/06
Filed: 1979-11-16
Abstract: The air gap reactor has a core, e.g. of low loss grain oriented electrical sheet steel, and at least one winding. A larger than normal capacitor is connected across the winding, and a further, unsaturated choke in series with it. Instead of an air gap, or gaps, the reactor core can have localised core section restrictions. The components of the circuit form a low loss parallel resonant circuit which ensures that even quite large output loadings cannot detune it. The high stored energy in core and capacitor assists in bridging several cycles of loss of input voltage. The application is mainly for small inverters. It operates as a smoothing circuit to reduce harmonies and produce a stabilised sinusoidal output.
Patent DE-2947319-A1 (DE)
Title: Spectacle frame for exchangeable lenses - with two snap fitting tabs for each lens
Inventor: ZECHEL JUERGEN
IPC: G02C1/06
Filed: 1979-11-22
Abstract: A spectacle frame which can be fitted with side blinkers has near the bridge rest for the nose a groove for the glass lens which extends over a sector of 90 deg. In the rest of the lens ring, the lens lies flat on the ring and is merely retained at two points by short retainer tabs, pref. of polyamide. The tabs contact the lens both on the periphery and on the flat. This results in a quick and easy exchange of the lenses if they need replacing. The risk of deformation by heating the frame is eliminated. The time needed for screw fastenings is saved.
