Title: Jaw bone implant as holder for artificial tooth - has blade and contoured neck sections encouraging tissue regeneration
Inventor: LINKOW LEONARD L
IPC: A61C8/00
Filed: 1975-05-23
Abstract: The oral implant for dental purposes permanently fixes an artificial tooth or teeth directly into the jaw bone and has a thin blade-like area inserted into the bone at the correct depth and connecting onto a neck (16) with a flange (50).

Title: Drill pipe tool joint - has nipple with bi-conical bore pressed into recesses of male and female taper thread ends
Inventor: LARI ION DR ING
IPC: F16L15/00
Filed: 1975-10-28
Abstract: A tool joint for drill pipes has at the inner end of the female taper thread a cylindrical recess, also at the inside of the male taper thread. A nipple with a biconical thickening on the inside is pressed into these recesses and forms an inside shell extending over the length of the taper thread at both ends. This relieves the male and female threads from bending moments applied to them and increases their tensile strength. It also relieves the critical stresses at the transition from tool joint to pipe and acts as an additional seal. The costs and downtimes caused by broken drill pipes are reduced.

Title: Dismantling large radioactive power station plant - using mobile equipment in containers assisted by permanent power station ancillary equipment
IPC: G21D1/00
Filed: 1976-08-25
Abstract: The parent patent describes a method of removing and rendering safe activated and/or contaminated components of a nuclear power plant; the various operations such as machining, cutting, burning, pressing etc., necessary for the dismantling, including chemical treatment decontamination and packaging are carried out with the assistance of the equipment already permanently available at the power plant, e.g. decontamination, ventilation, purification, and storage equipment, and where necessary also with the use of additional handling systems. All this work is carried out directly in the controlled area of the nuclear power plant. In this addn. the handling and treatment systems are incorporated in mobile, transportable containers; these can be coupled together in various combinations and are all mounted inside a bunker-like building which can be extended as desired. Pref. the bunker-like building is connected to the reactor containment building by means of a main safety lock. Used in partic. for the breaking down and removal of very large components such as complete heat exchangers or sections of heat exchangers for which no handling equipment is normally available on the site. By using transportable containers to house treatment systems such as a smelting furnace, a low-temp. disintegrator, pickling and washing chemical treatment plants and so on, this expensive equipment can be reused at a number of power stations.
