Title: Set of Paving Stones, Process and Device for Producing the Same
Inventor: HAGENAH GERHARD
IPC: E01C5/08
Filed: 1992-11-20
Abstract: In lawn covers made of paving stones (10) mutually separated by a relatively large gap, the paving stones are linked to each other so as not to move in relation to each other by a holding grid (11) imbedded in the paving stones (10) and composed of traction-resistant branches, so that traction forces are transmitted and the paving stones (10) are mutually secured as a linked group of paving stones by holding grid (11). The set of paving stones is produced in an essentially classical concrete stone mould. A moulding box (19) arranged on a bearing board (28) or draw plate (29) is horizontally subdivided along the horizontal plane (33), forming a top partial moulding box (34) and a bottom partial moulding box (35). the holding grid (11) is clamped between both partial moulding boxes during concreting. When a group of paving stones is ready, the bottom partial moulding box (35) withdrawn from the concrete stone mould. The finished product can then be removed as usual from the mould

Title: Apparatus and method for sequentially registering tool modules for a welding operation of a tube
Inventor: PIRL WILLIAM E
IPC: G21D1/00
Filed: 1994-10-07
Abstract: A frame is coupled to a remotely operable service arm (ROSA), and a rotatable carousel, in turn, is carried by the frame to position several tool modules used in a welding operation adjacent to a damaged tube in a tubesheet of a nuclear steam generator.  The arm positions an alignment module directly beneath the damaged tube and the module aligns the carousel.  The carousel is rotated to sequentially align and register a laser welding module,  a cleaning module,  and an inspection module with the damaged tube for a welding operation on a lower portion of the damaged tube in the tubesheet area.   One embodiment for the alignment module has a pneumatically operated pin which is operator controlled, and which has an increasing diameter from its distal end to obtain a gross to a vernier alignment of the carousel and, thus, a proper alignment for the remaining modules.   A further embodiment  provides  an  alignment  pin  which  is  automatically computer controlled without operator intervention.  Limit switches and grooves are used as a logic checking device for the proper positioning  of a  respective  module  in  the  frame,  and  a pneumatically operated radial pin holds the module in the frame.

Title: Process for the preparation of polyalkyl-1-oxa- diazaspirodecane compounds
Inventor: GAA KARL
IPC: C07D519/00
Filed: 1995-02-17
Abstract: The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The action is carried out in a solvent mixture of at least one alcohol and if appropriate an inert organic solvent in the presence of solid alkali metal hydroxide or a corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers the advantage that, by using a solvent mixture and dispensing with a phase transfer catalyst, a higher rate of reaction and therefore higher product quality with the same yield are achieved.   By dispensing with a phase transfer catalyst, which remains in the waste water and must be disposed of expensively, and by the reusability of the solvent mixture,  the process is more environment-friendly and more economical than processes known to date.

Abstract: A convolutional interleaver and addressing scheme are provided.  Up to B consecutive symbols containing errors can be interleaved such that they are separated from each other by at least N intervening symbols.  Memory, such as RAM, is configured to provide (B-1) cells of increasing size for storing symbols from a data stream.  A first one of the cells has M storage locations adapted to store M symbols.  Each successive one of the cells has M more storage locations than the immediately preceding cell for storing M more symbols than the immediately preceding cell, where M=N/B.  The cells are successively addressed to write a next symbol from the stream into a next write symbol location in a currently addressed cell and to read a symbol from the location of the currently addressed cell immediately following the next write symbol location.  The locations are accessed in a first revolving manner such that the last location in a cell is followed by the first location in that cell. The cells are addressed in a second revolving manner such that the (B-1)th cell is followed by the first cell, or vice versa.  An intervening transfer stage can be provided between the (B-1)th  cell and the first cell to directly transfer the next symbol to the interleaver output.  Each consecutive symbol from the stream is written into a next consecutive one of the cells.  A deinterleaver is provided having the same structure.

Patent CA-2149018-A1 (CA)
Title: Sealants
Inventor: TRAHEARN GUYDO REES
IPC: C08K3/38
Filed: 1993-11-11
Abstract: A fire retarding sealant comprises a silicone resin, a filler, a ceramic fire retardant such as zinc borate, a smoke suppressant such as stearate coated calcium hydroxide, and either aluminium hydroxide or magnesium hydroxide, preferably the former. The sealant is intumescent, and non-setting, and is intended for placement around pipes, cables and service penetrations in walls, floors and ceilings. At the temperatures encountered in fires, the aluminium hydroxide decomposes to form aluminium oxide and steam, the latter causing the sealant to intumesce while being relatively harmless to people (no halogen gases are evolved). The aluminium oxide and zinc borate form a crust on the intumesced sealant, providing a further fire retardant property.
