Title: Endless conveyor system for bulk material - has two paris of drive chains linked to front and rear of containers and running round diverting wheels
Inventor: IKEDA SATOSHI
IPC: B65G17/12
Filed: 1978-09-07
Abstract: A continuous conveyance system for a large volume of bulk load comprises a series of containers for receiving loose bulk to be conveyed, two pairs of endless drive chains (1, 1') respectively linked to the front and rear of the containers and arranged to run around turning wheels (A, B, C, D) disposed at the between a conveyor loading stations. Successive adjacent containers together form a continuous conveyor surface to receive bulk from a fill point. An unloading station is vertically and horizontally displaced from the loading station. Containers are successively inverted to discharge their contents into a discharge point. The runs of the chains and the linkage with the containers are such that the containers are held horizontal in their passage from the loading to the unloading station.

Title: Underground coal mine gallery driving unit - has part section support lowered before blasting moved for subsequent backfilling
Inventor: ADLER FRIEDRICH PROF DR ING
IPC: E21F15/00
Filed: 1978-09-14
Abstract: A partial cross-section is first worked out and supported, and then the complete cross-section is opened with the aid of blasting, the resultant heaped material being back-filled in the face area, in the process for driving forward mine working galleries (1) underground. Support for the part cross-section is lowered into position in section, before blasting. When blasting is completed it is moved into a position at an angle. The material torn away is backfilled with the support system raised, lowered and/or vibrated. This simplifies separation of waste material from coal, before coal conveyance to the surface.

Title: Steam gasification of coal or coke - with injection of gaseous ammonia or aq. metal oxide as catalyst
Inventor: SCHMIDT WOLFGANG
IPC: C10J3/16
Filed: 1978-12-06
Abstract: Gasification is effected in the presence of a catalyst comprising NH3 or an alkali(ne earth) metal oxide. The NH3 is introduced into the gasification reactor together with the feed steam; the metal oxides are introduced in the form of an aq. soln. of the oxide, or pref. of a cpd. which decomposes to the oxide on heating, which is sprayed into the reactor. The process increases the gasification rate and modifies the prod. gas compsn. without raising the gasification temp.; only small amts. of catalyst are required. The amt. of oxide catalyst used is pref. 0.05-2 (esp. 0.4-1.5) wt. % based on the C content of the coal or coke feed.

Title: Glued corner connection for an aquarium - joins plates chamfered at edges and bonded to tee section profile
Inventor: GIESEMANN ROLF DR
IPC: A01K63/00
Filed: 1979-02-26
Abstract: The two faces of two plates of glass to form a glued corner connection in an aquarium or terrarium are cut at an angle of 45 deg. to the plane of the plates. One leg of a "T"-form profile of a material considerably stiffer than the adhesive material, is inserted centrally between the two faces coated with glue, whilst the crossbar is turned to the inside of the vessel and lies against the glue to which it is bonded. The outer edge of each chamfered surface is shaped at a right angle to the outer surface of the plate so that the channel for the glue widens out in a "V". Conventional adhesive joints become critical when the mechanical loading across the cross-section is very different, and esp. when tension is set up. The joint described overcomes these problems.

Title: Fibre-optic de-multiplexing coupling - is dimensioned such that longest arriving wavelength passes into next coupled optic fibre conductor
Inventor: PETERMANN KLAUS DR
IPC: H04J14/02
Filed: 1979-07-04
Abstract: The optical coupling assembly, such as may be used for de-multiplexing, comprises a coupling (I,II) in which some of the light energy arriving in a first fibre conductor (1) passes into one or more second conductors (2,6). Upstream of the coupling area (K1,2; K1,6) the conductor (1) is curved (R1; R2) such that energy passes from the core into the mantel and from there into the core of the next conductor (2;6). The refractive index of the conductor (1) mantle is equal to or smaller than that of the next conductor (2;6) core. Where the conductor (1) carries more than one wavelength (lambda 1, 2,3), the coupling (I;II) is dimensioned such that the longest wavelength (lambda 3;2) passes into the next conductor (2;6).

Title: Positive let-off motion for warp-knitting machine - having electronic speed control circuit incorporating beam-dia. sensor
Inventor: DENZLER KARL
IPC: D04B27/22
Filed: 1979-09-28
Abstract: The warp beams of a warp-knitting machine are driven by independent let-off motors at a speed determined by an electronic control circuit wherein a reference signal representing the required speed, derived from the speed of the mainshaft and the required run-in, is compared with the actual speed of the warp beam. A swivelling arm which monitors the dia. of the beam is connected with a transducer which produces a signal to modify either the reference value or the actual speed value according the size of the beam. Arrangement is simple and inexpensive, but maintains a uniform let-off rate as dia of the beam decreases.

Title: Timed dimmer circuit suitable for stairway lighting - has starter capacitor charged through transistor lying across rectifying bridge
Inventor: PECHHOLD EBERHARD DIPL PHYS
IPC: H05B39/08
Filed: 1979-10-23
Abstract: The control circuit consists of a trigger, e.g. a dial, a starter capacitor preparing the ignition current of the electronic a.c. switch, a setting unit for the loading current of the starter capacitor and containing at least one controllable capacitor whose storage level can be independent of the charge state, and a charging circuit loading the controllable capacitor in dependence upon a switch. The setting unit determining the loading current of the starter capacitor (C1) uses a transistor (T3) whose switching path lies in the crossing branch of a rectifying bridge (D8-11). The charging current for the starter capacitor flows along this switching path. The control electrode of the transistor (T3) is connected to the capacitor (C4).

The two panels (1a,1b) are connected by one or more lengthways battens glued to them. The length of these battens is shorter than the interval between the end battens. The connecting battens are pref. located symmetrically to the transverse central axis of the board. This is endowed with adequate rigidity, without involving any difficulties in foam-filling.
Patent DE-2951932-A1 (DE)
Inventor: BOSCHULTE RAINER ING GRAD
IPC: G08B23/00
Filed: 1979-12-21
Abstract: In a remote control system which is operated by way of light wave guides a specific switching routine is executed at the receiving side upon failure of the system. As long as the remote control system functions properly, cyclically alternating signals, triggered at the transmission side, set a logic element at the receiving side so that the loads are connected for normal command-responsive operation. When the signals fail, or when a transmission is intentionally suppressed, the logic element is conditioned to cause execution of the specific switching routine. Given the design of the remote control system as a light signal control for traffic signals, the switching routine causes the connection of the STOP signal with simultaneous disconnection of the GO signals of the respectively affected light signal.
