Title: Vacuum filler for bottles - with small openings has filling pipe coaxially within vacuum pipe
IPC: B67C3/26
Filed: 1973-06-26
Abstract: Filling element for a vacuum filler for bottles with small openings, for liquids of different viscosities, has the liquid filling pipe coaxially within the vacuum tube, which ends before the outlet opening of the filling pipe. Specifically, a bottle is pressed against the rubber seal of a filling valve, and the cavity of the bottle is sealed atmos. pressure. The valve, projecting through the bottle opening into the cavity, evacuates it via the vacuum pipe and the filling pipe within it, so that the filling enters with high speed from the filling pipe. This is esp. useful for pharmaceutical and cosmetics bottles, which often have small openings.

Title: Adjustable valve stem stop for twin flow valve - has stepped bush for radial ball restriction
IPC: F16K31/10
Filed: 1974-02-14
Abstract: A twin solenoid operated valve, used to control a gas burner, has one set flow volume to ignite the burner and a second volume to supply the burner during operation. To control the valve stem movement which governs the two flow volumes the first solenoid lifts the valve body of its seat so that the upper end of the valve stem moves against a stop. The stop consists of a sleeved pin with screw adjustment. The sleeve carries a number of steel ball which are held in a fixed radial position by a bush with internal stepped diameters. When the second solenoid is operated, this restricting bush is lifted and the upper end of the valve stem is able to move its larger diameter past the steel balls thus full flow is obtained.

Abstract: Dry dust filter esp. for use in mines consists of a box like housing with a base for transport and a series of filter elements mounted on a vibrator such that the vibration moves the sepd. dust along the base and also cleans the elements. The dust is then sucked out via a fan into a pneumatic conveying line terminating in a wet cyclone in which the agglomerated dust is sepd. and discharged onto a further conveyor from which it no longer tends to blow off. The compressed air jet fan has a water spray device in its high pressure region. The vibratory conveying mechanism consists of a stroke-shock device, pref. on an air cushion. The whole filter is made as a container mounted on a beam upon which the stroke-shock vibrator acts.

Title: Mfr. of yellow or yellow-brown iron oxide pigments - using iron turnings, ferrous chloride soln., nitrobenzene and sulphites
Inventor: BELLEFONTAINE AUGUST DR
IPC: C09C1/24
Filed: 1974-03-27
Abstract: Yellow to yellow-brown iron oxide-hydrate pigments are mfd. by the oxidn. of iron and the simultaneous redn. of aromatic nitro-cpds. in the presence of iron salt solns. The oxidn. of the iron is carried out in the presence of the oxyacids of sulphur or their alkali(ne earth) metal salts where the average oxidn. stage of the sulphur is =5. The oxidn. of the iron is pref. carried out in the presence of the Na, K, NH4, Mg and/or the Ca salts of sulphurous acid, thiosulphurous acid, thio-sulphuric acid, dithionous acid, dithionic acid and/or pyrosulphurous acid, using 2-20% S w.r.t. the wt. of nitrobenzene. The iron oxide pigments obtd. may be used for the prodn. of yellow and red pigments. No foreign hydrolysable metal ions are used in the process which might form oxide or oxide-hydrate impurities in the iron oxide pigments so the iron oxide content in the latter is increased by 2-7%. By subsequent heating of the pigments, various shades of red can be obtd. The colour brightness and purity is superior to that of conventional pigments and the colouring power is increased by =45%; only a very small amt. of the sulphur cpds. are occluded in the pigments.

Title: Phase shift circulator for extremely high power pulses - consists of coupler magic-T and phase shift elements
Inventor: HASHEIDER HUBERT DIPL ING
IPC: H01P1/397
Filed: 1974-03-28
Abstract: Phase shift circulator for extremely high power pulses consists of a 3dB coupler, a magic T and two non reciprocating quadrature phase shift networks operating in opposite directions and placed next to each other. The non-reciprocating phase shift is effected by pre-magnetised strips outside the centre of the waveguide. The two phase shift elements are made up from ferrite-yttrium-iron garnets with varying dysprosium content. The direction of propagation of the wave to the 3dB coupler is caused by a waveguide with a ferrite of higher disprosium content producing a quadrature phase shift in one direction than the waveguide doing the same in the other direction.

Title: Digital speed control for electric drives - has correction signal derived from difference between actual and required angles
Inventor: SCHAUDT HANS DIPL ING
IPC: H02P5/56
Filed: 1974-05-31
Abstract: The actual and measured angles are cyclically sampled and the digital speed control obtains a correction signal from the difference between signals representing the required angle of the drive and its actual angle. The subtraction circuit has an output connected to a D/A converter that controls a regulator regulating the supply of the slave motor synchronised with the master motor that produces the required angle signal. The actual and required angle signals are derived by counting the outputs of two pulse generators coupled one to the master motor shaft and the other to the slave motor shaft.

Title: HF receive aerial on trains - receives from track-side aerial and has two elements located in maximum and minimum areas of field
Inventor: BREITENBACH OTTO
IPC: H01Q1/32
Filed: 1974-06-14
Abstract: The HF receive aerial for tracked vehicles, receives signals from an aerial laid along the side of the track and consists of two elements (3, 4). These two aerial elements are separated from one another so that one (3) of them lies in a region of maximum field strength when the other (4) is situated in a region of minimum field strength. The two aerial elements are connected so that the voltages from both at their common terminal have the same phase. (The aerial system may be used e.g. for transmitting video signals to a train). Then aerial shape reduces the effects of signal fluctuation cheaply.

Title: Energy absorbing airbag system - with gas container behind bumper to force air to folded airbag
Inventor: WECKENMANN ALBERT DR ING
IPC: B60R21/26
Filed: 1974-10-17
Abstract: The front bumper of the vehicle is fitted with a compressed air container (5) behind it and sealed by a pressure relief valve. The outlet line from the container is taken through the pressure relief valve to a folded airbag system (2) inside the vehicle. The system acts as a passive safety system, requiring no complex electronic collision monitors or gas release circuits. For added effect a non-return valve in the line prevents air from flowing back if the front container is ruptured. Several pressure compensating chambers can be included in the line to provide a controlled inflation of the airbag.

Title: Tilting conveyor for tree trunk sorting - has self guiding cradles tilted by horizontal turn buttons to tip off trunk
Inventor: AIGNER JOSEF
IPC: B07C5/14
Filed: 1974-12-03
Abstract: A tree trunk is supported on two cradles, one at each end, and moved along rails on an endless chain as far as its proper delivery point. There a stop tilts the cradle to one side or the other, dislodging the trunk. The pedestals have downward projections to run between the rails, so that the cradle will guide itself. Instead of tilting the cradles by vertically-moving stops, which afterwards sank into the rails, a stop moves horizontally to displace the cradle from the upper to a lower rail by means of the sloping opposite edge of the pedestal projection.
