Title: Silicate coated metals - esp gas chromatography appts by coating with polysiloxane and oxidising
IPC: G01N30/56
Filed: 1970-11-17
Abstract: Silicate coatings are produced on surfaces, esp. metals, by coating the surface with a thin layer of a polysiloxane, and converting the polysiloxane layer into a silicate layer bonded to the surface by heating under oxidising conditions. Used for forming a chemically resistant glassy surface on metal apparatus, such as reactor and esp. Golay columns for gas chromatography. The catalytic action of the metal surface is inactivated, while its valuable mechanical properties are maintained. The polysiloxane is pref. dimethylpolysiloxane, phenylmethylpolysiloxane, or cyanoethylpolysiloxane. Heating takes place at a maximum temp. of 300 degrees C, and oxidn. is effected by use of air. The silicate treated surface is silylated by treatment with hexamethyldisilazane, or dimethylchlorosilane.

Title: Electro-magnetic inductive shock absorber - transforms impact energy into electrical energy to operate protective devices
Inventor: MERKEL REINER JOACHIM
IPC: H02K7/18
Filed: 1973-07-16
Abstract: Moving parts are connected to their supports by means of an electromagnetic induction system. The wheel of e.g. a motor car is connected to a link made from a conducting material. The link passes through an electric coil and can hinge or slide at its end in a support. A current is passed through the coil which generates a magnetic flux in and around the coil. If the link moves in the magnetic field, an electric current will be induced in it, which sets up a magnetic field opposed to that of the coil. This field will exert a damping action on the movement.

Title: Endless conveyor for separating printed sheets - has two rows of grippers circulating on endless web which engage emerging sheets
Inventor: SOEHLKE AXEL
IPC: B41F13/54
Filed: 1974-04-10
Abstract: The printed sheets emerge onto the endless conveyor in two parallel overlapping streams. The grippers are arranged with one row on one side of the conveyor and the other one on the remaining conveyor side. One row of grippers engages the individual folded sheets in one stream on a section of the sheet which is not covered by the neighbouring stream. The other row of grippers engages similarly the second stream and the grippers are so operated that, as the sheets are moved along the conveyor, the two initially overlapping streams become laterally separated from one another to form two individual streams. A further conveyor placed next to the endless belt conveyor receives one of these streams.

Title: Amplifier with variable gain outside dead zone - has positive feedback and loop containing two antiseries Zener diodes
Inventor: BARTOSCH EKKERT
IPC: G06G7/25
Filed: 1974-11-15
Abstract: The amplifier consists of an operational amplifier IC with its inverting input coupled via a feedback resistor to its output. The output is connected over two anti-series zener diodes (12, 14) in the positive feedback path to a second resistor coupled to the amplifier's non-inverting input. The output signal is taken from the zener diode/second resistor junction. The advantage lies in the simplicity of the circuit. The amplifier has a dead zone for both polarities, and can be used as a comparator or Schmitt trigger with adjustable hysteresis. Four resistors are provided: a feed (4), a feed back (6), a linking (8), and a voltage divider (10).
Patent DE-2500417-A1 (DE)
Title: Disturbance compensation for frequency modulated stored signal - may be used to transfer signals to one or more channels and has plastics joint of reduced cross section
Inventor: SEIFERT HANS-PETER DR ING
IPC: H04N9/802
Filed: 1975-01-07
Abstract: The apparatus simply filters out a constant frequency used for other purposed as a part of the signal, passing this through an amplitude limiter and a frequency discriminator, and using the output from this to compensate for the disturbances by applying it with the correct phase and amplitude to the demodulated signal. If there is no such frequency in the signal, it can be added. This frequency may be higher than the frequency range of the signal, and may be recorded on the storage material either directly, or in a modulated or otherwise altered forms. Use of a supplementary track to carry the reference signal is avoided.
