Patent PT-100310-B (PT)
IPC: E02D27/48
Filed: 1992-03-27
Abstract: The invention concerns a procedure for salvaging stone- walled buildings and the like that are found to be in poor condition, with deformations and misalignment, either horizontal or vertical, characterised by the use of auxiliary metal structures for transferring local loads and distributing tensions, especially by means of transferring tensions to deep underground layers carried out in order to eliminate, or practically eliminate, vibrations produced in the ground by the salvaging work. According to the invention, this is done by making holes 8 in the ground 7, with a diamond-tipped drill, into the bottom of which is injected a first layer of concrete 9 into which a metal rod 10 partially penetrates, simply inserted and not driven, then filling the space between the rod 10 and the sides of the hole 8 with concrete 11. <IMAGE>

Title: Automatic machine for sealing the tubular cover end of salamis and sausages
Inventor: MARTINEK
IPC: A22C11/02
Filed: 1980-11-13
Abstract: A system for automatically closing one end of a shirred casing strand. A strand is to be automatically presented to an associated closer mechanism (46) in alignment therewith and under a preselected pressure. A transfer device (44) is provided for receiving a doffed strand (40), transferring the strand transversely and then moving the strand longitudinally so that an end of the strand engages the closer (46). A gripping mechanism is provided which includes a pair of jaws (98) having opposing clamp elements (102) of a generally V-shape or angled cross section. The two jaws are simultaneously movable either together or apart and are urged apart by compression springs (104). A fluid cylinder-actuated linkage urges the jaws towards closed positions. By varying the closing force, the clamp members (90) can be first moved to a pre-set spacing providing a receptacle into which a doffed strand of a predetermined size may be readily slid. Then by increasing the pressure of the cylinder, the strand may be sufficiently tightly gripped to prevent relative movement during the closing operation. The closer members are separated to release a closed strand at the end of the closing operation. By varying the pressure to the cylinder in the receptacle forming stage of the clamping members, the size of the receptacle may be adjusted in accordance with variations in size of casing strands to be handled. A control system for the automatic operation of the transfer device in conjunction with the closing device is provided.
