Patent DE-2404340-A1 (DE)
Title: Universal pallet shelving with front and side holes - pallet supports at right angles and parallel to shelving
Inventor: JUERGENS WALTER DR ING
IPC: A47B57/40
Filed: 1974-01-30
Abstract: The pallet shelving has a framework with columns which have independent rows of holes on the sides and at the front so that pallet supports can be suspended which run both at right angles to the shelving and parallel to it. The two rows of holes are preferably set at slightly different heights so that the cross-sections of the columns are not unduly weakened. The holes not required for the pallet support can be used for attaching stabilizing means. The pallet supports are preferably in the form of angle irons. The universal application could find special application in shops and stores with the necessity of rapidly accommodating articles of various shapes and sizes.
Patent DE-2406374-A1 (DE)
Title: Divan with adjustable outer parts - has bearing spring arrangement operated by body weight and locked manually
Inventor: KERSTHOLT FRITZ
IPC: A47C20/08
Filed: 1974-02-11
Abstract: The divan with adjustable outer ends has at least one bearing spring arrangement which connects the outer part of the divan directly or through an arm to the basic frame so that this outer part can be raised and then fixed in a position relative to the basic frame. At least one of the outer parts is mounted on a horizontal spindle located on the basic frame and when stressed can be swivelled clockwise or anticlockwise out of each position provided the locking means have been disengaged. The adjustment of the bed is thus carried out only by the body weight of the user. Locking of parts is carried out by hand which is possible even when the user is lying down.

Title: Polymerising 4-methyl-pentene-1 - using Ziegler Natta catalyst at high temps
Inventor: VOSS HARRO DR
IPC: C08F10/14
Filed: 1974-02-14
Abstract: Polymers of 4-methylpentene-1 alone or with up to 10 wt. % of other 2-18C -alpha-mono-olefines as comonomer, are obtd. by polymsn. at 90-150 degrees in the presence of hydrogen at a partial pressure of 0.1 to 10.00 atm., and using a Ziegler-Natta catalyst system comprising (a) a TiCl3 component and (b) an alkylaluminium component, the atomic ratio of Ti:Al in the system amtg. to from 1:1 to 1:100. By use of temp. of 90-150 degrees C, which is higher than used in the otherwise comparable known process, a higher yield per unit catalyst and per unit time is obtD. without deleterious effects on product crystallinity. The polymers are valuable for making transparent moulded or injection moulded articles which are heat resistant to 150 degrees C.
Patent DE-2417207-A1 (DE)
Title: Bending mandrel for production of chain links - has stepped cross section for prebending link blank before closing sides
Inventor: ESSER PAUL
IPC: B21L3/00
Filed: 1974-04-09
Abstract: The bending mandrel of a chain link bending machine has two profiles of different shape. The first profile which is the stronger one, is used to pre-bend the middle of the straight blank so that it curves towards the inside of the link. The mandrel is then axially moved to place the cross section which corresponds with the link shape behind the unfinished link. Bending rollers then close the link thus finishing it. The pre-bent section is now straight again, therefore a link with two parallel sides is obtained.

Title: AC generator circuit for motor vehicles - has switches which cut out part of star phase windings at higher speeds to raise efficiency
Inventor: RAGALY ISTVAN DIPL ING
IPC: H02J7/14
Filed: 1974-08-02
Abstract: The a.c. generator circuit, for motor vehicles, has the 3 star-coupled phase windings connected to a rectifier consisting of 6 diodes. The excitation winding is coupled via excitation diodes to the rectifier's inputs. The rectifier's output charges a battery. Three switches separate the ends of the phase windings from the cathodes of the minus diodes (i.e. the diodes connected to the battery's negative terminal). The switches disconnect part of the phase windings from the circuit at higher speeds. Tappings are connected via a second set of minus diodes to the negative pole. The switches are controlled by a relay and the circuit is of high efficiency.

Title: Chromatographic determination of toxic dissolved substances - esp. aflatoxin, using different comparison substances
Inventor: POLZHOFER KURT
IPC: G01N30/95
Filed: 1974-09-26
Abstract: The concn. of dissolved substances is determined chromatographically and the intensity or fluorescence of the chromatogram bands or spots, opt. after their development with suitable chemicals, is compared with that of a known concn. of the substance under estimation. In this procedure, the comparison substance comprises substances not under determination but having the same colour or fluorescence characteristics as the bands or spots of the substance under determination, opt. after a corresp. development. The method is used for the determination of toxic substances, and esp. the toxic and deadly aflatoxin.

Title: Tool for tightening a hose clip - in which the end of the clip is gripped between rollers
Inventor: ZEIDLER SIEGMUND
IPC: F16L33/08
Filed: 1974-12-24
Abstract: The free end of the clip is fed through a bridge-piece which is mounted on the other end of the clip. The free end has regularly spaced square holes, protrusions on the bridge-piece engage with these holes and act as ratchets to prevent the clip from loosening. The hose clip is tightened by means of a special tool, which consists of a bracket in which two rollers are mounted. The surfaces of the rollers are roughened, so that the clip end can be clamped between the rollers. Worm wheels are cut on the rollers and a worm is mounted between the rollers. The worm is driven from the handle of the tool. Instead of a worm drive, a ratchet drive can be used.

Title: Ionisation engine for aerospace vehicles - produces propulsive force by reaction of electrons and positrons in resonance chambers
Inventor: HAEYRINEN URPO TAPIO
IPC: F03H1/00
Filed: 1974-12-27
Abstract: The engine has a closed annular acceleration tunnel (1) containing hydrogen or other suitable ionised gas. An electromagnet (2) produces a magnetic field perpendicular to the axis of the annulus by means of poles (3) along the top and bottom of the annulus. The tension of a generator applied to poles (4) on the sides of the annulus produces an electric field perpendicular both to the axis of the annulus and to the magnetic field. The combined fields accelerate particles in a spiral path and aprt of the energy is diverted into hollow resonance chambers (5) at the sides of the annulus. Within these positrons and electrons are destroyed with the production of a resulting force which is available for propulsion or lift.

Title: Variable setting load dependant fluid valve - has pair of valves in series providing on-off and throttle control
Inventor: BUDZICH TADEUSZ
IPC: F15B13/04
Filed: 1975-05-12
Abstract: A housing forms a hydraulic fluid inlet chamber, a fluid bed chamber, a fluid outlet chamber and a hydraulic fluid drain. A fist valve connects the load chamber selectively with the inlet chamber and the outlet chamber and there is a variable orifice between the outlet chamber and the hydraulic fluid drain. This responds to a setting of the fist valve. A second valve chokes the hydraulic fluid flow between the outlet chamber and the hydraulic drain and the second valve can maintain a constant pressure difference at the variable orifice when the load chamber and the outlet chamber are connected and the outlet chamber is under pressure.
