Title: Flow measurement cell with optical arrangement - is for differentiating between fluid and gas in cell by means of absorbence measurement
Inventor: WILHELM SIEGFRIED
IPC: G01N21/05
Filed: 1975-08-21
Abstract: A cell for the measurement of flow is designed to enable differentiation between the cell being filed with gas of fluid in order to eliminate measurement errors caused by air bubbles. The cell also permits the absorbence of the fluid to be measured. A relatively monochromatic light beam (4) produced by a light source (1), filter (2), and aperture (3) is directed through the glass wall (8) of the cell (6) through which the fluid and/or gas flows. The inner face (5) of the glass wall is flat and inclined at such an angle that when the cell contains gas the light is totally reflected and does not enter the cell. When the cell contains fluid light passes through it to a light sensor (11), being attenuated according to the absorbence of the fluid.

Title: CIRCUIT FOR KEYBOARD FEEDING INFORMATION - by use of input annaand locking keys uses timing pulses on multiplex principle operated by integrated semiconductor logic
Inventor: NOMIYA KOSEI
IPC: G06F3/02
Filed: 1976-04-15

Patent DE-2623419-A1 (DE)
Title: Forming insulated zone on silicon substrate - by multistep process comprising etching and silicon dioxide layers formation and removal (NL301176)
Inventor: SAKAI HIDEO
IPC: H01L21/3105
Filed: 1976-05-25
Abstract: Formation of an insulated zone on the surface of a silicon substrate is effected by a stepwise process. In the first step, the surface layer of the silicon substrate is removed by etching on the part designated to be an insulated zone. In the second step, a SiO2-layer is formed on the etched zone; the thickness of this SiO2 layer being larger than the depth of the etching so that the SiO2 layer protrudes from the surface of the silicon substrate. In the third step, another layer of SiO2 is formed over the insulated zone and its vicinity. In the fourth step, the SiO2 layer formed in the third step is entirely removed together with a part of the SiO2 layer formed in the second step, so that the surface of the latter, at least in its central part, is on the same level as the newly formed surface of the silicon substrate in the vicinity of the insulated zone. This method is used in semiconductor technology. The formation of a SiO2 layer on an etched part of a silicon substrate usually results in the formation of a protrusion around the periphery of the insulated zone, which hinders a tight packing of semiconductor elements and may obstruct the formation of electric leads on the silicon substrate. The height of this protrusion is about halved by the process described above so that it becomes negligible.

Title: Propylene oxide prodn. from propylene glycol mono-acetates - produced from allyl acetate and acetic acid on sulphonated cation exchanger
Inventor: DAUMILLER GUENTHER DIPL CHEM D
IPC: C07D301/02
Filed: 1976-06-02
Abstract: In the prodn. of propylene oxide (1) from propylene glycol 1,2-monoacetates (II) in the gas phase in the presence of basic materials (III), allyl acetate (IV) is reacted with excess acetic acid (V) in the presence of an organic sulphonated cation exchanger (VI) with a particle size of 10-200 mu m., which is suspended in the liquid reaction mixt. After removing the excess (V) from the mixt. of propylene glycol 1,2-diacetate (VII) and (V) formed, (VII) is hydrolysed to a mixt. of (VII) and (II) in 2:1 to 1:3 molar ratio with 50-200 mole % water in the presence of (VI). The unreacted water and (V) formed are removed, and the mixt. of (VII) and (II) is converted to (I) in the gas phase at 350-425 degrees C, in the presence of (III) and the (V) formed is recycled, whilst the unchanged (VII) and (II) are also recycled. The process avoids the use of dissolved noble metal catalysts and associated catalyst losses or very corrosive catalysts requiring cost appts. for corrosion prevention and recovery. (IV) is prepd. by reacting propylene with (V) and O2 in the gas phase on catalysts contg. Pd, giving a crude mixt. of (IV), (V) and water, which is dehydrated by azeotropic distn. with (IV) as reflux.

Title: Large injection moulding transferred onto conveyor alongside mould - by transverse pusher plate which orients then transfers moulding
Inventor: BARAINSKY RUDOLF
IPC: B29C31/00
Filed: 1976-07-15
Abstract: A conveyor system for removing large injection moulded prods. which have been deposited beneath the injection mould comprises a slide or pusher which can be moved transversely across the deposition space and, in its at-rest position, is situated laterally of the mould; a stripper prevents this pusher from pulling anything back in the wrong direction; a barrier on the opposite discharge side from the mould ensures that the moulding is turned over into the correct position before being discharged onto the conveyor. The drive mechanism for the pusher drives it with a double reciprocating motion, the first driving stroke turning the moulding into the correct orientation, and the second stroke pushing it out onto the conveyor. Very large mouldings can be transferred to a conveyor situated at the side of the mould, thus decreasing the necessary overall depth. It is not necessary to reach manually with hooks or rods beneath the mould to remove the moulding.

Title: Controlled oscillator for fault locating in carrier wave system - has variable resistor shunting oscillating transistor providing low power consumption
Inventor: THANHAEUSER GERHARD DIPL ING
IPC: H03B5/36
Filed: 1976-07-20
Abstract: The controlled oscillator, for fault locating in broadband carrier-wave systems, has very low power consumption and can therefore be used with other identical oscillators to cover the system's bandwidth. The oscillating transistor (T1), the isolating transistor (T2) and a Zener diode (Z) are connected in series. (The Zener diode provides a reference voltage for the control circuit). A variable resistor is connected in parallel with the oscillating transistor's collector/emitter path and its resistance depends upon the output voltage of the oscillator. The variable resistor consists of a third transistor (T3) in parallel with a capacitor (C7) and coupled by its base via another transistor (T4) to a rectifier (D3, C9) at the oscillator's output.

Title: Permanent magnet excited motor - incorporates system for intensive magnet cooling to prevent flux reduction due to high temp.
Inventor: VOLKRODT WOLFGANG DIPL ING DR
IPC: H02K1/32
Filed: 1976-12-30
Abstract: The rotor of the permanent magnet excited machine contains ferrite magnets which are clamped between steel laminations acting to guide and concentrate the magnetic flux. These laminations are arranged to produce air ducts through which cooling air from an integral or external fan is passed. The air passing through these ducts removes heat which would otherwise reach the magnets from the stator winding, and which could reduce their active flux by raising the magnet temperature. Typically one third of the machine cooling air quantity is arranged to pass through the rotor ducts.
