Title: Oil vapour diluent gas mixture preparation for burner - in which diluent gas permits low oil vapour pressure thus lower operating temperatures
Inventor: REED ROBERT D
IPC: F23K5/10
Filed: 1978-11-22
Abstract: Appts. to burn liquid fuels in a gaseous fuel burner, which includes preparatory appts. for atomisation of liquid fuel oil pref. by a diluent gs. Then heating of the fuel droplets and diluent gas so as to completely vaporise the liquid fuel. If atomisation is by other means, diluent gas is added prior ot vaporisation heating. The resulting oil vapour-diluent gas mixture then goes to a burner which utilises the central orifice of a conventional gas burner. Primary air is induced into the burner tube due to the high velocity of jets of oil vapour-diluent gas. The diluent gas permits low vapour pressure of oil vapour and thus lower operating temperature. For the use of gaseous fuel, the same burner is utilised. The diluent gas can be pref. any noncombutsible and non-oxygen containing gas.

Title: Plug connector with handle forming housing - has nut insertable into insulator slot up to wall mounted lug, where it is located by edge grip
Inventor: HOLST GERD ING GRAD
IPC: H01R13/516
Filed: 1978-12-30
Abstract: The housing carries a contact supporting insulator (2), secured by a nut in a housing recess, where it engages a bolt screwed radially into the insulator. The location by this means can be made simpler and more certain by using a common nut (6) instead of special inserts, or screw treads in th e insulation. A slot (9) extends axially along the insulator (2). The nut (6) is pushed along the slot until it bears against the end of the slot and at the same time latches behind a lug (10) extending across the slot. With the nut held in this position the locating bolt (5) can be tightened without fear of damaging the insulation or stripping the threads. The nut edges are then partly covered and gripped by the insulator. The nut may be pushed through a threaded slot portion which may have a guide surface for the bolt.

Title: Rectifier system earth fault protection circuit - has parallel amplifiers for negative and positive lines supplying rectifier connected to relay
Inventor: FRISSE WILLY
IPC: H02H3/32
Filed: 1979-03-03
Abstract: The protection circuit for a rectifier system with a converter but without a separating transformer for the power supply system with earthed protective conductors has shunt connections in the positive and negative lines at the output of the converter. These are connected to two parallel d.c. separating amplifiers with voltage dividers at their outputs. The dividers are connected across a rectifier bridge followed by a d.c. relay. A d.c. voltage proportional to a fall in voltage at the converter output is thus applied to the relay, being amplified by the separating amplifiers. The polarity of the output voltage shows whether an earthing fault occurs in either the positive or negative line at the converter output.

Title: Coal gasification device - includes an element for coal slag removal comprising a water cooled metal e.g. copper casting
Inventor: ANDERSON JOHN ALFRED
IPC: C10J3/08
Filed: 1979-08-01
Abstract: A casting element for use in a coal gasification device comprises a high thermal conductivity metal casting. composed of a metallic pipe having a section for circulating a liquid cooling agent, an upper throat over which the coal slag supplied from the gasification device flows and a central orifice for removing the slag. The surface of the upper throad is angled inwardly and towards the base and is connected to the orifice. The pipe for the cooling agent undergoes no deformation during the casting of any surrounding metal, is enclosed by the casting, forms a conduit for cooling agent near the surface of the throat of the orifice and is spaced from these surfaces by 6.35-38/mm. The pipe ends project beyond the exterior of the casting so as to provide an inlet and outlet for the cooling agent. The element is less subject to chemical attack, to erosion and corrosion than prior elements.

Title: Async. multichannel radio receiver - demodulates both in-phase and out-of-phase components of modulated received signal
Inventor: HERSHBERGER DAVID L
IPC: H04H1/00
Filed: 1979-08-16
Abstract: The receiver receives a modulated signal comprising modulated components in and out of phase and demodulates both of these componentS. The envelope of the modulated received signal is detected and an envelope signal generated. The phase of the modulated signal is detected and a phase signal generated. The envelope signal is multiplied by the phase signal to produce a product signal that in general is the same as the signal modulated onto the phase-displaced component. The receiver requires no phase-reference circuit and is therefore cheaper.

Title: Video telephone subscriber relative position presentation - using continuous call back to match subscriber's position so that movement from camera produces weaker signals
Inventor: GEISER GEORG DR ING
IPC: H04N7/14
Filed: 1980-02-26
Abstract: The process assists in maintaining the relative position w.r.t. the camera in a video telephone system.

Title: Automatic foundry moulding and casting plant - where one turntable is used both as casting track and mould cooling track so min floor space is required
Inventor: WEBER WILHELM
IPC: B22D5/02
Filed: 1980-07-12
Abstract: Empty moulding boxes are fed into a sand moulding machine, and are filled with sand to make a cope and drag. The cope is placed on the drag to make a boxed mould, which travels along a mould track to a swivel table. The swivel table transfers the boxed mould to the periphery of a turntable forming a casting track. After casting, and with the stepwise rotation of the turntable, the filled boxed mould reaches a discharge station, where the box is pushed radially outwards onto a hoist. The hoist lifts the sand cope and drag out of the boxes, which are returned to the sand moulding machine, whereas the cope and drag travel along a cooling path on the turntable.
