Title: Joining metal surfaces by electric resistance welding - esp. plug and grid plate for nuclear reactor using protuberance and recess to ensure close surface contact
Inventor: LELLI G
IPC: B23K11/02
Filed: 1976-03-26
Granted: 1982-03-10
Abstract: Flat surfaces of two metal bodies are joined by electric resistance welding. At the middle of each of the welding surface areas, a tapered protuberance is formed on one of the bodies. The crests of the protuberances lie in a plane parallel to the flat surfaces. A recess is also formed for each protuberance, at least as large in vol. as the protuberance. The protuberances contact the other flat surface, and a voltage is applied to melt them. The surfaces can then be brought into close mating contact. The stiffness of the join is improved since the surfaces are bonded very closely with no clearance between them. Stresses are equally distributed between all the fuel elements. The process is esp. suitable for joining a fuel element, end plug to a grid plate in a calandria tube nuclear reactor.

Title: Two bladed propeller for light applications - has asymmetrical blades balanced dynamically about joint centre of gravity
IPC: B63H/
Filed: 1978-06-29
Granted: 1987-02-04
Abstract: The propeller has one elliptically shaped blade (13) which has a stiffening bar (14) along one edge. This blade has a propulsive effect. At its inner end the propulsive blade is joined to a balancing blade (12) which is a compact weight of any shape. Its weight is such that the centre of gravity of the assembly is near the inner end of the propulsive blade. When allowed to fall freely the propeller begins to rotate about its centre of gravity and the rate of fall is retarded. It has applications in fireworks and publicity devices and can also be used to propel bodies through fluids.

Patent MX-167625-B (MX)
Inventor: ROSENFLED ARON M
IPC: B65D55/02
Filed: 1988-08-08
Abstract: The invention relates to a laminated tamper-evident structure which exhibits an irreversible colour change upon delamination. The structure includes a laminate of at least two layers (10,12) capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between an adjacent two of the layers. The strength of attachment among the layers of the laminate is such that the laminate can be uniformly and reliably peeled apart at the interface between the adjacent two layers. An overlying flexible strip (14) of transparent or translucent material is adhered to the laminate to facilitate the peeling operation. Upon peeling apart the laminate, the generated colour is irreversibly lost, thus providing evidence that the structure has been tampered with. The structure can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering.

Patent PT-71824-B (PT)
Title: Multi-programming data processing system process suspension
IPC: G06F9/46
Filed: 1980-09-22
Abstract: Each process in a multi-process computing system using so-called capabilities may have associated with it a process dumpstack protected by the capability mechanism. The functions of this dumpstack are (i) to provide the state of the process at the point at which it was suspended and (ii) to stack (or nest) information relating to the invoked procedures (i.e. sub-routines) of the process. Thus there is a fixed sized portion containing principally the machine registers, the indicators and the watchdog timer values and a variable sized portion containing information related to each nested procedure. Each stack link is of fixed size and contains three items:- relativised instruction address, the code block capability and process capability pointer list block capability. This arrangement is enhanced to allowtwo additional classes of information to be stored in each link namely (a) an indication of the data and capability registers preserved during the domain change procedure and (b) descriptors for local storage segments. The use of descriptors for local storage allows a pool of storage particular to the process to be allocated on a segmented basis with the security of the capability mechanism extended into that local storage area. The descriptors for local storage segments resemble closely SCT entries (i.e. they contain sumcheck, base and limit values) and they are relative to a new protected stack, the local store stack, which is referenced by a hidden capability register C(L). The processor module is provided with a new instruction "subset local store" for use in local store segment allocation and automatic de-allocation occurs when a return is made from the procedure in which the local segment was allocated. Such allocation and de-allocation mechanisms use the indications which takes the form of a primary descriptor held in the most significant eight bits of the IAR word. This descriptor is allocated as follows:- (i) zero, no stacked registers or local segments allocated, (ii) m.s.b. = 1, stacked registers to be passed and (iii) I.s.b. 1-7 = 1, indicates the number of local store segments allocated. Associated with the stacked register set is a one word descriptor which indicates the registers stacked.
