Title: Reinforced concrete units end butt joint - involves bolt with nuts through slit inside and outside loop shackle
Inventor: DOBLIN ROBERT DIPL-ING
IPC: E04B1/04
Filed: 1977-07-15
Abstract: The butt jointed connection is for reinforced-concrete components with interfacing protruding fittings concreted in at their ends, for screwing together the intervening space between the ends being then filled with concrete. These fittings form a loop shackle protruding from one end face (14), with a slit (44) open on one side, while the fitting on the facing end takes the form of a threaded bolt (20) with nuts (22, 24). This enables the shackle to be displaced, by relative movement of the components (10, 12) along their end faces, to a position where the bolt penetrates the slit, with one nut sited inside the shackle and the other outside. The two nuts can then be firmly screwed onto the shackle. This is versatile and firm, while allowing precise adjustment of interval on site without calling for great skill.

Title: Reaction chamber ignition system - has igniter mounted on block lifted from opening in top of chamber and replaced by plug
Inventor: BAUER HANS
IPC: F23M11/02
Filed: 1978-09-16
Abstract: The igniter for a reaction chamber is mounted in a tapered block (9) which fits into a hole (1) in the top (2) of the chamber. After ignition, a temperature sensor operates when the temperature rises to release a securing catch system (12, 13) so that the block with the igniter mounted on it is lifted by a spring (10). The block is then secured in the raised position by a swinging arm (6) attached to an upper plate. At the same time, as this arm is secured in its upper position, a catch (8) mounted on it releases a stop (5) mounted on the side of a tapered plug (3) mounted on another swinging arm (4). This allows the plug to swing down and fit into the hole from which the tapered block was released, sealing it again.
