Patent DE-2549462-A1 (DE)
Title: Insulating refractory ceramic materials contg. spheroidal voids - for extruded articles e.g. oxygen tuyeres, thermocouple sheaths, etc.
IPC: B28B3/20
Filed: 1975-11-01
Abstract: Insulating refractory ceramic materials contain spheroidal voids larger than normal pores. The voids are created by admixing to the ceramic raw material round particles of pref. a hydrocarbon which volatilises at the firing temp. This material can be used for different thermal insulations, but is esp. suitable for articles produced by extrusion, because it does not show any texture (nonuniform density, varying orientation of grains) inherent in the known extruded products (such texture reduces the resistance to thermal shocks). If the material contains up to 50 vol.% of voids its compressive strength is not excessively reduced, whilst its heat-insulating properties are greatly improved and its weight is correspondingly diminished. The pref. applications include oxygen-blasting tuyeres, protective sheath for thermocouples or pressure-measuring devices, etc.
Patent DE-2552298-A1 (DE)
Title: Fixed bed filter for gases - having periodic removal and cleaning of granular filter medium
Inventor: ARASHI NORIO
IPC: B01D53/86
Filed: 1975-11-21
Abstract: Process for filtering a gas stream in a fixed bed type particulate medium uses periodic extraction of a portion of the particulate medium from the filter layer at the base of the bed and then recycling of this. This extraction occurs when the filter pressure drop exceeds a predetermined level. The height of the bed is checked and the extraction halted should it fall below a predetermined level. The extraction can also occur at preset time intervals. The quantity should correspond to 200 mm. of the bed height. To carry out the extraction the bed must be designed so that it can move. The system avoids the loss of on stream life found with beds which have to be stripped down for cleaning and also the attrition which occurs when agitation or shaking is used.

Title: Closed circuit system for generating mechanical energy - cools and liquefies working fluid after expansion through turbine
Inventor: POCRNJA ANTON DIPL ING
IPC: F01K25/00
Filed: 1977-03-30
Abstract: A closed circuit systemuses a working fluid such as SO2, SO2F2, or SF6 which begins the working cycle as a liquid which receives heat from a relatively low temp. source. A second source of heat with a temp. between ambient and 600K evaporates the liquid and raises its pressure. The working fluid is then expanded through a turbine which can be used to drive a generator. The working fluid leaving the turbine is then cooled in two stages. The first stage cools the fluid to a temp. near its liquefaction and the second stage liquefies the fluid so that it can repeat the working cycle.

Title: Parallel alignment of rock drill slide - uses laser beam illuminating three glass bulbs for shot blasting holes in tunnels
Inventor: BLASE GOETZ
IPC: E21B47/00
Filed: 1977-05-02
Abstract: When parallel shotholes have to be drilled during driving tunnels and headings in mines, a lack of parallelism caused by the conventional mechanical and hydraulic booms results in high explosive consumption. This can be avoided and the drill rig itself need not be previously aligned if a laser (6) with a revolving right-angle prism (7) is attached parallel to the rock drill slide (5). A guide rod (3) which is inserted into a pilot borehole (2) in the tunnel face (1) carries three markers (4), eg glass bulbs which light up when hit by a laser beam. The slide is aligned properly when all three markers light up simultaneously.
