Title: Spectrochemical analyser for atomic absorption and emission - for analytical examination of trace elements in chemical matrix uses HF plasma
Inventor: SCHMIDER PAUL DIPL PHYS DR
IPC: G01N21/68
Filed: 1974-08-05
Abstract: A resonant radiation source is used to produce the resonant wavelengths of the element to be detected. There are means for alternate operation of the h.f. field and the resonance radiator, with a spectroscopic device for the element wavelength separation, and a detector for radiation absorbed or emitted by the atoms of the vapour. The elements are atomised and excited in a dielectric cell in a low pressure noble gas h.f. plasma, whose frequency is shifted in phase by 90 deg. with respect to that of the resonance radiation source; the cell is connected through a valve to the noble gas reservoir for maintaining constant the noble gas partial pressure; an electric switching and evaluating device generates output signals derived from the four measurement conditions resulting from pulsed operation of the h.f. field and the radiation source.

Title: Decontamination treatment of sewage by sludge separation - and passing of purified liquid through successive tanks containing air curtains
IPC: G21F9/20
Filed: 1974-09-13
Abstract: A decontamination plant is used for retaining liq. which contains radioactive substances until the reactivity has decayed to an acceptable level. The liq. is first passed through a precipitation device, where the solids are sepd., then the remaining liq. is passed in succession through a series of cascade vessels, each of which contains aeration pipes, so that circulation of the liq. is produced, thus delaying the passage of the liq. through these tanks. The air is pref. introduced by peforated pipes, so as to produce air bubble curtains transversely across the path of the liq. Specif., at least two such curtains of bubbles are produced in each tank; each may be a flat curtain or a cross-shaped curtain. Plant is esp. used for the treatment of sewage discharged from nuclear medical centres, where the sewage may contain radioactivity. The arrangement enables the use of large decay tanks to be dispensed with, by concentrating the solids. The aeration and circulation of the sepd. liq. prevents it from becoming stagnant. The whole appts. can be quantitatively designed to suit the discharge rate. All the cascade vessels can be identical and therefore mutually interchangeable. Moving mechanical parts such as agitators are largely eliminated.

Title: Radiation protection device against cosmic and terrestrial radiation - has anodized aluninium plates forming condenser interacting with radiation
Inventor: LANIO HANS
IPC: A61N1/16
Filed: 1974-09-17
Abstract: A radiation protection unit to combat cosmic and terrestrial radiation has a flat condenser (1) with two round aluminium plates (1) with edges (2) pointing outwards which are completely anodized (3) and glued (4) to the condenser such that the anodized layers (3) of the aluminium plates (1) act internally as a dielectric and externally as an easily cleanable protective coating. The plates (1) are mounted on three or more vertical supports (5) made from a thin isolating material and produce areas of perturbation in the cosmic or terrestrial radiation impinging on and passing near their tips. Deprived of effective conducting paths the undesirable radiations are prevented from reaching humans, animals, plants and sensitive materials such as films and medicine.

Title: Open-plan office prefabricated partition elements connection - with grooves joint rails screening battens and top and bottom connectors
Inventor: HILDEBRANDT NORBERT
IPC: E04B2/74
Filed: 1974-10-24
Abstract: The assembled partition wall elements and connecting units are esp. for the creation of enclosed working spaces in large open-plan offices. There are grooves in the end faces of the elements. The connecting devices include two shaped joint rails, a front and a rear screening batten, and top and bottom connector pieces, with interlocking latch elements.

The rails fit into the accommodating grooves on the wall elements, where they can be fixed in place by screwing or other means. The rails may incorporate lengthways running rows of holes, not covered by the screening battens, for suspension of functional components after assembly. Erection is by snapping the parts into place, and connector pieces' space between elements can be used e.g. for cables.
Patent DE-2454649-A1 (DE)
Title: Model electric trains controlled by ultra sonic transmitter - permits several trains to run from one transformer
Inventor: STIEHLER WOLFGANG
IPC: A63H30/04
Filed: 1974-11-18
Abstract: The model railway track is supplied with a constant voltage from a transformer. Each locomotive is provided with two ultra-sonic receivers which receive signals of different frequencies generated by an ultra-sonic transmitter. One of the receivers when excited by the signal causes the electric motor to accelerate the locomotive in the forward direction. When the second receiver is excited the locomotive is decelerated or accelerated rearwards. If no signal is transmitted the locomotive continues to run at constant speed. A number of locomotives corresponding to the number of frequencies can thus be operated simultaneously. The ultra-sonic transmitter can be operated from a battery or from the mains.

Title: Plastics support plate for counters etc. - has channels for wires and slots for connecting through to counters and inserting wires
Inventor: THEISS KARL
IPC: H02B1/015
Filed: 1974-11-28
Abstract: The plastics support plate is intended for electric installation units, such as counters etc. and is constructed from an extruded, multiple-cavity, hollow profile that has longitudinal slots in its walls facing the counters. The slots are bounded by spring flaps or lips that are angled slightly inwards into the slots to give tapered entrances. The cavity or channel behind each slot carries the wiring for the counters installation. The rear of the profile is double-walled for strength. The advantage lies in the insulating plastics affording to the insulated wires in the profile channels an additional insulation in the simplest possible way.

Title: Electro magnetic piston pump - reciprocating movement of the piston is carried out by connection to a current source
Inventor: NOMURA ATUSHI
IPC: F04B17/04
Filed: 1975-01-27
Abstract: Electromagnetic reciprocating piston pump with a cylinder, a magnetic piston having in and outlet ends with an adjustable bearing in the cylinder and with a flow channel running through the magnetic piston. The cylinder limits a pump chamber which surrounds the inlet end of the piston and serves to receive the pressure medium. Reciprocating movement of the piston is achieved by a magnetic spool co-axial to the magnetic piston and a current source connected to the magnetic spool for the selective exciting of the magnetic spool. A locking valve or non return valve is positioned in the flow channel with a valve seat rigidly connected to the cylinder. The locking valve is fitted behind the outlet end of the piston and the current source provides semi rectified current so that when current supply is interrupted the outlet of the pressure medium from the pump is completely barred.

Title: Terminal wire soldering system - connects set of closely spaced wires to terminals at same spacing using temporary crimping of wires
Inventor: POINTNER MARTIN
IPC: H01R43/02
Filed: 1975-11-12
Abstract: The first stage in the connection and soldering procedure involves formation of a temporary connection between the bared wire ends and the terminals. After establishment of this contact, the wires and the terminals are then firmly connected by soldering. The temporary connection between wires (3, 4) of a ribbon cable (1) and terminals (5, 6) of the component (7) are bent and staggered, so that the connection points (8, 9) lie alternately on both sides of a common symmetry axis (10), at equal distances from it.
Patent DE-2552602-A1 (DE)
Title: LF operation of inverter fed machine - is facilitated by adjustment of stator current vector phase position by modulation of basic frequency
Inventor: BLUMENTHAL MICHAEL DR ING
Filed: 1975-11-24
Abstract: In machines fed via inverters the stator current vector can only take up certain fixed positions, for example six equally spaced points for a six pulse inverter, which interferes with satisfactory operation at very low frequencies. To overcome this limitation the basic frequency is modulated by adding a frequency at least one order of magnitude greater. Using this modulating frequency the stator current vector can be selectively switched between its basic positions so that the resultant average value coincides with that required for satisfactory operation at the basic frequency selected. Typically the higher frequency is added by means of a triangular voltage form auxiliary supply.
