Title: Refractory heat-insulating material - contg expanded diatomite particles
Inventor: JOHANSSON STIG FRITHOF
IPC: C04B20/06
Filed: 1975-05-28
Abstract: Refractory, heat-insulating matl. is produced from 40-90% of diatomite particles (SiO2 content 65-85%, Al2O3 content 5-15%) expanded by rapidly heating to 1200-1400 degrees C. The expanded particles (pref. 6 mm) can be bound together by a refractory binder such as an aluminate cement or alumina. Structural matls. that can withstand temps. well above 1000 degrees C (approaching the m.pt. of the diatomite i.e. about 1400 degrees C) are produced in relatively inexpensive manner. The bulk density of the expanded diatomite particles is 200-600 kg/m3; their heat conductivity is low (0.2 kcal/m.hr. degrees C at about 600 degrees C). The expanded particles can be used for filling spaces between walls, or they can be bound together by means of a binder to form plates, building stones, etc. The rapid heating suppresses the formation of the undesirable cristobalite.

Title: Pivoted mounting for towing hook - has mounting shaft secured in axial bore by split ring in groove
Inventor: MAYER ROMAN
IPC: B60D1/50
Filed: 1975-09-26
Abstract: The towing hook (1) has amounting shaft (3) located in an axial bore in the mounting block. The end of the shaft has a groove in which is clipped a split ring (5).

Patent DE-2618648-A1 (DE)
Title: Fuel element coffin arrester device to retard sinking - if dropped by brake shoes pressed against vertical guides
Inventor: WALTER HEINZ ING GRAD
IPC: G21F5/08
Filed: 1976-04-28
Abstract: A supporting frame is fixed to the bottom of the coffin and comprises vertical guides, which permit a vertical sliding movement of an arrester plate relative to the coffin shown. This arrester plate has notches or grooves at two opposite edges, which can slide vertically relative to vertical guide bars or rails, stationarily mounted in the cooling pond. The solid arms between these notches are tranversed by horizontal bores which contain pins, normally not in contact with the stationary vertical guide rails. If the coffin is accidentally dropped, the sudden increase in its sinking speed forces the arrester plate upwards against the roof of the supporting frame, (i.e. relative to the base of the coffin), so that it strikes limit switches mounted upon this roof; these limit switches trigger a closure movement of wedges which cause the pins to move outwards in their bores and thus press against the sides of the vertical guide rails. Used of partic. for the handling of heavy coffins, up to 120 tons, for removing spent fuel elements after a decay period in a cooling prod. The arrangement pregents damage to the coffin it is is accidentally dropped by the lifting crane or tackle.
