Patent DE-2726582-A1 (DE)
Title: Mine gallery overhead conveyor system - has brake with arms swung inwards to force shoes against web of overhead beam
Inventor: WIDIGER HANS
IPC: B61H9/02
Filed: 1977-06-13
Abstract: A mine conveyor with carriages travelling along a beam mounted under the roof of the mine gallery includes a braking device with a pneumatic or hydraulic actuator. This operates so that two arms are swung inwards about a hinge point at the bottom of each to that a shoe is forced inwards each side onto the web of the I-beam between them. These are forced apart against spring force by a piston between them. This is in turn operated by a servo piston at each end of a channel at right angles to the travel of the piston. These arms are positioned between longitudinal bars parallel to this channel, the end covers being mounted on these arms.

Title: Door or window frame section connector - has locking devices causing components to move together when coupling up
IPC: F16B5/06
Filed: 1977-07-01
Abstract: The connector between two structural components, particularly parts of a door or window, is in one piece and of E or U section with locking devices, and of thermally insulating material. Its coupling strips have, running in the axial direction, locking devices which, due to oblique surfaces formed in the locking zone, cause the components to move towards each other during the coupling process, and its strut portion determines the distance between them when in service. The locking devices on the strips can be saw teeth (10, 11) working in conjunction with oblique surfaces (8, 9).

Title: Meta-isocyanato:benzyl isocyanate - useful as a monomer for polyurethane prodn.
Inventor: BACSKAI ROBERT
IPC: C08G18/76
Filed: 1977-09-08
Abstract: Meta-isocyanatobenzyl isocyanate (I) is novel. It can be prepd. by reacting m-amino benzylamine with phosgene, opt. in a suitable solvent, at 75-150 degrees C.

Title: AC load four quadrant inverter - uses controlled rectifier bridges in antiparallel across DC supply as power feedback inverter and rectifier
Inventor: BOEHRINGER ANDREAS PROF
IPC: H02M7/515

IPC: C01G39/02
Filed: 1978-07-11
Abstract: Mo oxide (MoO3) (I) prodn. by oxidn. of Mo sulphide (MoS2) concentrates (II) contg. metallic impurities (III) involves converting (II) to an aq. slurry and oxidising this in an autoclave at elevated temp. and elevated O2 partial pressure filtering off (I), neutralising the first filtrate contg. H2SO4 and filtering again. The novel feature is that a high (I) yield is obtd. and (III) are recovered by the use of the following stages: (1) Recirculation of unfiltered oxidised slurry to the slurry prepn. stage until the H2SO4) concn. reaches 80-120 (100)g/l, before filtering off (I). (2) Recirculation fo the first filtrate after neutralisation to pH 0.9-1.5(0.9) with chalk, the CaSO4 formed being filtered off to give a second filtrate (IV), and continuing until (III) are sufficiently enriched in (IV). (3) Neutralisation of (IV) to pH 2.5 with alkali hydroxide and then treating to recover Fe molybdate (V) and (III). The Mo yield is 90-100%, whilst the recovery of (III) e.g. Re and Cu, has environmental and economic advantages.

Title: Plastics curtain rail slider - has free support leg insertable into vertical groove on suspension element to give form fitting connection
Inventor: GRAF FALKO
IPC: A47H15/04
Filed: 1978-08-08
Abstract: The curtain slider is made from plastics material and has a suspension element running in the curtain rail and an eye can be inserted into a vertical groove on the suspension element to make a form fitting connection with that element. The vertical groove transforms a recess capable of holding a strengthened support leg end, which is formed by two extensions (7a, 7b) which project sideways. The extensions include lower surfaces which are in an operating connection with the holding recess (8) and which rise from a lowest central point forwards and backwards in the direction of the inserting movement of the free support leg. The suspension element (2) has a flat form with a rounded off front edge so that the eye (3) can be closed solely by pressure on to the free support leg (6) and without lifting the support legs.

Title: Motor vehicle tyre pressure drop indicator - has diaphragm located between reference and tyre pressures to move away from contact when tyre pressure drops
Inventor: PRUSS GUENTER
IPC: H01H35/34
Filed: 1978-08-09
Abstract: The indicator comprises a circular corrugated diaphragm (4) exposed to tyre pressure and to a reference pressure in a chamber (3). Any drop in tyre pressure causes diaphragm to move away from contact (5) and break a circuit thus providing an indication. The detector may be diametrically opposed to the tyre inflation valve or may be combined with that valve. The pressure chamber (3) contains air or other gas at atmospheric or higher pressure and provides temperature compensation and assists resilient return of diaphragm. Small magnets may be provided on the diaphragm (4) and contact (5).

Title: Thermal power station control system - has multiplier to correlate pseudo-random binary signal with pressure-dependent efficiency condition signal
Inventor: FUKUSHIMA KOICHIRO
IPC: F01K13/02
Filed: 1979-02-13
Abstract: The power station control system varies the main steam pressure as a function of the station loading. It comprises a generator producing a periodic pseudo-random binary signal which is then added to a signal representing the main steam pressure. A further circuit correlates a signal representing a pressure-dependent efficiency parameter with a signal representing an auto-correlation function of the binary signal. The output of the second circuit is added to the binary signal the result being added to the main steam pressure signal, thus correcting it. The correlator may consist of a multiplier stage.

Patent DE-2932200-A1 (DE)
Title: Plastics seal, esp. polyolefin or polyamide for metal closure - made from sinterable powder is unplasticised and inert to pharmaceuticals and foodstuffs (OE 15.11.79)
Inventor: HENSS PETER
IPC: C09K3/10
Filed: 1979-08-08
Abstract: Sealant for metal closures consists of unplasticised plastics, pref. based on polyolefin or polyamide, the insert being in the form of film produced from sinterable powder. Accurate dosing is effected by prepressing or premoulding; or by electrostatic charging and hence agglomeration. The sealing and cold flow properties can be improved by incorporation of inorganic additives, e.g. pigments or fillers, whilst the addn. of organic and inorganic fillers causing gas evolution on heating gives an elastic foam. Powdered stabilisers can be added to increase the resistance to chemicals, esp. peroxides, whilst adhesion improvers may also be added. The seals are inert towards pharmaceuticals and foodstuff, unlike those contg. plasticisers, adhere well and can be made easily in the right size.
