Patent DE-2813430-A1 (DE)
Title: Coke oven gas offtake pipe repair - by exhausting hot gases through charging hole before refractory spraying operation
IPC: C10B29/06
Filed: 1978-03-29
Abstract: The lining of the gas offtake pipe of a coke oven is repaired by spraying a refractory composition on the damaged parts. Before the spraying operation the noxious hot gases are extracted by injector action through the open charging hole of the oven and this action is then reduced until the chimney efect in the offtake pipe is just compensated. The result is than the repair operation is not impeded by streams of hot gas. It prevents the detrimental effect on the hot lining when temps are made to introduce a blast of cold air.

Title: Quartz glass optical fibre with high tensile strength - obtd. by coating rod blank with boric oxide, or boric oxide and silica, prior to drawing of fibre
Inventor: GRABMAIER JOSEF DIPL PHYS DR R
IPC: C03B37/012
Filed: 1978-12-13
Abstract: The fibre is made by drawing a quartz glass blank; and the bank is first coated with a layer (I) preventing the crystallisation of silica to tridymite and/or cristobalite on its surface. Boric oxide, or boric oxide and silica, are pref. used as layer (I). When a conventional blank is heated in a drawing furnace tridymite and cristobalite small crystals form on its surface and do not completely melt; on cooling, these crystals peel off, leaving microfissures which reduce the tensile strength of waveguide fibres. The invention minimises the formation of such crystals.

Title: Weighing and grading fowls hanging from shackles - of moving overhead conveyor using balance arms adapted to catch and lift shackles
Inventor: MEYN PIETER
IPC: B07C5/18
Filed: 1978-07-05
Abstract: Weighing appts. for fowl hanging from shackles of a continuously moving overhead conveyor includes balance arms extending radially outwardly from a central shaft. The outer end of each arm is adapted to grip and lift a shackle so that it is no longer supported by the conveyor. The inner end of each arm cooperates with a load cell located in the axis of the central shaft.
