Title: Removal of pyritic sulphur and ash from coal - in two=stage liquefaction process using solvent
Inventor: FARCASIU MALVINA
IPC: C10G1/00
Filed: 1977-11-02
Abstract: Pyritic sulphur and ash are removed from coal by (a) dissolving in a hydrogen-donor solvent at 427 degrees C for a time selected to minimise hydrogen loss and aromatisation of the solvent, sepg. the pyritic sulphur, ash and undissolved coal, and (b) heating at 315-538 degrees C for sufficient time to obtain a pure product and remove at least part of the solvent. Used in prodn. of clean solid fuel for power station or domestic use, boiler fuel, coke and materials suitable for hydrogenation to obtain turbine fuels. Short contact times, e.g. 1-5 mins., are required in (a) which with the low temps. used prevents coke formation, and gives a readily-filtered product. Hydrogen consumption is kept to a min. and recovery of solvent increased.

Title: High speed machine bearing - has discs with radial holes to eject air during starting and liquid when at speed
Inventor: PELTIER HENRI
IPC: F16C32/06
Filed: 1977-12-16
Abstract: The stationary shaft is surrounded by a sleeve (5) forming part of a rotor. The shaft has a number of discs (3) with radial holes which eject liquid by centrifugal force so that it forms a liquid ring in the annular space (8). When the rotor is stationary, it is supported by the tapered rings (9). On starting, air is supplied through the hole (2) so that the rotor runs on an air bearing. The inner ring (9) is then moved axially and liquid supplied through the discs (3). Rings of high pressure liquid are generated in the space (8) due to centrifugal force and these liquid rings support the rotor (5).
Patent DE-2807880-A1 (DE)
Inventor: KOSTURA MICHAL DIPL ING
IPC: B22D27/04
Filed: 1978-02-24
Abstract: The device has a closed ring circuit (12-15) which passes through the mould (10) and in which are arranged a storage means (20) for latent heat, a recirculating pump (30), a heat exchanger (40) and a heater (50). All these units are monitored by a control unit (60). If the mould (10) is hot, the heat is fed via the heat transfer medium to the storage means (20); excess heat is released in the heat exchanger (40). If, on the other hand, it is necessary to preheat the cold mould, the heat is released from the storage means (20); if this quantity of heat is not sufficient, the heater (50) is switched on in addition. The amount of supplementary heat supplied can be reduced. <IMAGE>

Title: Semi-formant vocoder with analyser on sending side - obtains frequencies of formants at receiving end by transposition of baseband frequency to required formant frequency
Inventor: SCHROEDER HARTMUT DR ING
IPC: G10L19/00
Filed: 1978-08-04
Abstract: Frequency and amplitude of at least the second and third formant of the speech signal above the baseband are determined on the sending side by an analyser. data about these values together with the baseband are transmitted in a coded form. At the receiving end the decoded signals control a synthesiser for recovery of the speech signal. The formants are synthesised by transposition of the baseband to the formant frequency. Modulation frequency for the frequency transposition is determined by the difference of the respective formant frequency and the first formant frequency. Formant amplitudes are related to the mean amplitude of the baseband.

Title: Plastic coating for flat capacitors - by cross field heating and mechanical swivelling in pulsating fluidised bed
Inventor: KNAB HEINRICH
IPC: H01G2/12
Filed: 1978-08-25
Abstract: Flattened roll or layer capacitors, particularly those using polyethylene terephthalate or polycarbonate as the dielectric are coated by a plastic layer in a fluidised bed. The capacitors are heated during this operation by turning them mechanically through the cross field of a high-frequency heating coil. The capacitors are mounted in the container with the plastic powder on swivelling bars with holders for the connecting wires. A high-frequency induction coil produces a cross field with the lines of flux, with an angle of incidence which changes continually because of the swivelling angle beta. This coating process is ideal for 100% automation and results in minimum manufacturing costs. A min. temp. rise ensures freedom from bubbles and shrinkage cavities.

Title: Transfer printing process - using transfer sheet consisting of cut=out letters, symbols, etc. adhesively mounted on a paper substrate
Inventor: HOLTZ HERMANN
IPC: B41M3/12
Filed: 1978-11-03
Abstract: Transfer printable letters, symbols, numbers, etc. are cut or stamped out of a sheet consisting essentially of a paper carrier of suitable quality carrying on one side a layer of sublimate or heat transferrable dye, and on the other side a layer of mounting adhesive. The adhesive side of the sheet may carry a layer of release paper. The cutout letters, etc. are assembled on a sheet of backing paper in the form of a mirror image of the desired legend. The mounting adhesive used allows wrongly placed symbols to be removed from the paper and reset into the desired position. The sheet is then applied to the substrate to be printed, such as a textile material, polyester film, melamine-coated surfaces, etc., and the legend is transferred by applying heat and press., e.g. using a hot iron at approx. 200 degrees C. The process allows a virtually unlimited range of legends, designs and symbols to be applied to a variety of substrates without the necessity for stencils, etc..

Title: Internal combustion engine for heavy goods vehicle - has variable level oil sump to increase braking effect of engine during braking
Inventor: BUHL HANS WILHELM
IPC: F02D9/06
Filed: 1979-01-31
Abstract: The engine has a sump (2) below the crankcase (3). A pump (5) removes oil from the sump to a separate reservoir (8) so that the oil level in the sump is very low. A separate pump (11) delivers oil from the reservoir to the engine from which it drains to the sump. A connection (15) from the reservoir to the sump contains a normally closed valve (16). When additional braking is required the valve is opened by a driver operated control and oil floods the sump and crankcase. The cranks then rotate within an oil bath and there is increased friction to retard the engine and vehicle.

Title: Slow-acting brake assembly - is for fold-down table tops of bedside tables and has brake cylinders set in guide tubes attached to frame for silent action
Inventor: NEITZKE CLAUS
IPC: A47B79/00
Filed: 1979-10-03
Abstract: The tabletop which is fixed to the bedside table frame so that it can be raised and lowered into and from a position of use is coupled for articulated movement to two brake cylinders (30) which are guided in guide tubes (25) fixed to the frame. The brake cylinders operate when the tabletop is raised from its position of use and set parallel to the frame. The brake forces produced on the brake cylinders counteract the actual weight of the tabletop so that the latter can be slowly and silently lowered by hand until reaching the lower end position against the frame which is defined by a stopper (26) which limits the fall space.
