Inventor: WEITZEL INGO DIPL PHYS
IPC: C01G23/07
Filed: 1975-09-02
Abstract: Layers of TiO2 are made, esp. for the prodn. of a capacitor, by passing a Ti halide and an oxidant over a heated metal substrate. The substrate is held at 750-850 degrees C and the halide is evaporated at 250-320 degrees C. Pref. the substrate is at 820 degrees C and the halide is TiI4 evaporated at 280 degrees C., the oxidant being O2 or steam. A T-shaped tubular reactor is is pref. used with the substrate at the junction of the "T", argon being used to carry the halide and the oxidant through two branches of the "T" to the substrate. One or more metal halides may be included with the TiI4 vapour to form layers of mixed oxides or titanates. A very pure rutile phase can be obtd., 1-20 mu m thick, using a relatively low reaction temp. high capacities can be achieved due to the thin layers, and the substrate can be Pt, Au, Ni, Ag, Tu, or Al. Due to very few dislocations in the rutile phase, the ageing effects of capacitors are reduced.

Title: Forest fire extinguishing method - proposes starting lines of controlled small fires ahead of main fire to check its progress
Inventor: MARSAL TALLO JAIME
IPC: A62C3/02
Filed: 1975-12-04
Abstract: The proposal concerns method for fighting forest fires by starting a line of small controlled fires ahead of the main fire. The controlled fires would be started by teams of two, one using a flame thrower and the other a fire extinguisher. The local small fires started by the flame thrower would be kemp in check and prevented from spreading in the wrong direction by the man using the fire extinguisher. The deliberately started local fire is allowed to burn itself out, so that when the main fire reaches the spot the burntout area acts as a checking device. The proposal envisages the supply of fuel and extinguishing agent to the team by helicopter, which directs also the operation by advising the teams in respect of the location and direction of the line of the controlled fires.

Title: Solid fuel stove for domestic heating - has hinged sides controlled by bimetal strip to improve air circulation
Inventor: ANSCHUETZ THEO
IPC: F24B7/00
Filed: 1975-12-10
Abstract: A solid fuel stove has an outer casing round a fixed internal compartment (1). There is a space (3) between the inner stove outer casing through which air circulates. It is warmed by contact with the heated inner stove and circulates by natural convection. The top (4) of the outer casing is perforated. The two sides (2) of the outer case are hinged (5) at the bottom of the stove. They are moved about these hinges by a bimetal strip so that as the temperature rises a larger gap is opened at the top between the sides and the top of the oven. This increases the cross sectional area available for flow as convection increases and also permits direct radiation from the inside.

Title: Differential pressure indicator with overload protection - has automatic blocking and bypass valves to prevent damage to diaphragm
Inventor: FISCHER GERHARD
IPC: G01L7/08
Filed: 1975-12-13
Abstract: The differential pressure indicator consists of an instrument housing (1) constructed in two halves separated by a diaphragm (6). The diaphragm is attached at its centre (9) to an operating rod (10) and extension piece which actuates the indicator needle (11). The outer ends of the operating rod are attached to bellows (13) and valve seats (15). Each valve seat engages with the inner face of the pressure chambers (2)(3) if excessive pressure causes the operating rod to move to the limit of its travel through large displacement of the diaphragm. Overloading and therefore damage to the diaphragm is thus avoided by the blocking action of the valves. To avoid the necessity of a manually-operated pressure release following over-pressure, an automatic, spring-loaded balancing valve (19) is fitted between the inlet chambers and central pressure chamber.

Title: Reciprocating engine with rotating piston - has cup shaped piston functioning as sleeve valve and corresponding cylinder head projection
Inventor: DYLLA GUENTHER
IPC: F02B75/30
Filed: 1976-03-30
Abstract: The reciprocating engine with a rotating piston functioning as a sleeve valve is generally as set out in Patent Application P 25 28 122.5, with a right-angle drive from a toothed wheel on the crankpin to another on the connecting rod (8) causing the piston rotation. This brings a port in the piston in line with others in the casing as necessary to permit the cycle gas flow; rotation rate and casing port position vary with the cycle (2-stroke or 4-stroke). The piston (1) is now-cup shaped to reduce thermal stresses; the cylinder head underside has a corresponding projection (32). Both have similarly tapering sides. The opening connecting combustion chamber (33) and casing gas passages is now a short radial duct (20a) in the piston cup wall. Piston rings are not needed as the cup/cylinder head walls seal the combustion chamber.

Title: Vibrating sieve for winnowing - has two vibrating tables moving in opposite directions to counterbalance each other
Inventor: SCHNELLBACHER KURT
IPC: B07B1/42
Filed: 1976-04-02
Abstract: The vibrating sieve for winnowing consists of two tables mounted on rollers on a framework. An electric motor mounted on a sub-frame attached to the table drives a crankshaft through the pulley belt and pulley. The crankshaft has a connecting rod with its other end attached by a pin to a bracket forming part of the second table. When the crankshaft is rotated it causes both tables to vibrate in the horizontal plane but each table always moves in the opposite direction to the other so that all the dynamic forces are cancelled out and there is no residual force on the base structure. The base structure does not vibrate and noise is reduced.
Patent DE-2614450-A1 (DE)
Title: Electric machine for producing periodic mechanical movement - uses one or more movable permanent magnets arranged in magnetic field
IPC: H02K41/02
Filed: 1976-04-03
Abstract: The machine produces periodic mechanical movement by means of permanent magnets. It utilises the largely energy-free pole reversal of the permanent magnets for gaining mechanical work from the actual magnetic forces involved. One or more additional, movable, permanent magnets are arranged in the magnetic field of one or more permanent magnets. The movable permanent magnets (16) are impressed with a magnetic force periodically alternating in its direction by periodic electrical pole reversal of the magnetic poles of the stationary and/or of the movable permanent magnets. Electrical windings are arranged on the permanent magnets for electrical pole reversal of the magnetic poles, and the windings have current pulses passed through them in a direction opposing the direction of the magnetic flux.
Patent DE-2614527-A1 (DE)
Title: Film cassette with automatic film speed register - has scanner with control device activated by camera handling and providing mechanical load release
Inventor: FAUTH GUENTER
IPC: G03B7/00
Filed: 1976-04-03
Abstract: a rib (2) on the cassette indicates the film speed. When the cassette is inserted in the camera, this rib positions a lever (6, 7). Closing the camera back, or cocking the shutter, or transporting the film, causes a second lever (10) to lift the first (6) slightly away from the rib (2), so that the cassette lies free in the camera. A cassette containing a film of a different speed has no rib, so that the first lever rests further down (spring 8), and the second remains out of engagement with it (at 10). Then a stop (16) is no longer placed in the path of the rod (18) that brings the exposure-correcting element into operation.
Patent DE-2615797-A1 (DE)
Title: Automatic radio transmission of road conditions to vehicles - uses encoded transmissions from local transmitters to activate corresponding displays in the passing vehicles
Inventor: ROEMER HORST
IPC: G08G1/0967
Filed: 1976-04-10
Abstract: The simple equipment uses radio transmitted encoded signals for warning passing traffic of local hazards and other road conditions. A decoding receiver in each vehicle activates a display in the vehicle corresponding to the hazard. A transmitting unit (4) which can conveniently be powered by solar energy, is placed beside the hazard (2) on the road (1). This transmits one or more encoded messages, typically a road narrowing warning and a mandatory speed limit, on a very short wavelength. An approaching vehicle (5) receives this signal, decodes it and displays it to the driver with a visual and perhaps an audio warning apparatus.

Title: Connecting web with flange for parquet floor - has pliable connecting web with flange held in floor plates to accommodate expansion and shrinking stresses
Inventor: HEWENER HANS JOSEF
IPC: E04F15/04
Filed: 1976-04-13
Abstract: The connection web with flange connects plates resting flat on supporting substrate. The arrangement is used esp. for connecting prefabricated parquet floor elements. This pliable connection arrangement replaces rigid connectors such as adhesives or nails. The expansion and the shrinking stresses of the connection web are accommodated by this pliable system. The tolerances caused by the moisture absorption are accommodated elastically by the connecting system. This prevents cracking. The connecting web prevents overlapping of the plate edges on uneven substrate. The connection web is loaded in tension when the plates expand. On contraction of the plates the connection web pulls the plates together and prevents gap formation.

Title: Transfer rotor on horizontal bottle conveyor to labeling machine - has pneumatically operated disc brake to regulate transfer rate
Inventor: SEIFERT GUENTER DIPL ING
IPC: B65C9/02
Filed: 1976-09-29
Abstract: A bottle conveyor includes a transfer rotor (2) which regulates the conveyor capacity. The vertical shaft of the rotor has a brake disc (5, 6) attached to its lower end. A similar non rotating brake plate (7, 8) is placed axially next to the rotor brake plate (5) inside a cylindrical brake housing. When a sensor on the conveyor provides a signal which requires the rotor to stop, an air cylinder (10) is pressurised. The outstroking piston (12) applies an axial force on the lower brake disc (7) through the piston rod (11). This produces friction between the two brake plates so that the rotor shaft (3) is stopped.
