Abstract: A method and inhibitor are provided for substantially diminishing the deleterious effects of a bomb blast such as is common place with terrorist activities. A generally flexible container (2 & 3,25,36) filled with a liquid, generally water, is shaped and adapted to substantially cover a bomb (12,30) to obscure substantially all open spaces from the bomb. The water serves to absorb a large proportion of the energy of the bomb blast and therefore reduces the most dangerous effects of bombs namely that of secondary shrapnel which generally does the most damage and the container and water prevent, to a substantial extent, any primary shrapnel or other debris from being blown out with substantial force. The invention also provides special containers of various different designs as well as a method of manufacturing such containers which are preferably of a resilient nature.

Abstract: A set-point adjuster (1) contains a memory (7), in which desired values for the temperature in a domestic hot water reservoir, which differ for individual time intervals, are stored. A logic element (3) determines whether the temperature in the domestic hot water reservoir is below or above the set temperature and in the region of limiting values stored in a limiting value memory (2). If the temperature in the domestic hot water reservoir at an instant tn is lower than the set point stored in the memory (7) for said instant, a new set point, which is higher than the previous set point for said instant, is written by the logic element (3) into the memory (7) for the instant tn-1. A corresponding correction also takes place in the inverse case. The set-point adjuster (1) thus learns at which instant inside a calendar week which set temperatures are required in order, in accordance with the user's habits always to be able to make available a sufficient amount of sufficiently hot water. <IMAGE>

Abstract: An electronically commutated motor has substan­tially constant air gap energy to reduce cogging. A rotat­able assembly has a plurality of permanent magnet elements which rotate about an axis of rotation as the rotatable assembly rotates. The elements are oriented with respect to said axis of rotation to provide a magnetic field with lines of flux along a plane forming a skew angle of s₁ mechanical degrees with respect to the axis of rotation, wherein s is not equal to zero. The elements may be provided with an unmagnetized portion referred to as a phantom skew. A sta­tionary assembly is in magnetic coupling relation with the permanent magnet elements of the rotatable assembly and has t spaced teeth with adjacent teeth defining a slot therebe­tween, wherein t is positive integer. Each tooth has a surface adjacent the rotatable assembly having one or more notches forming a skew angle of s₂ mechanical degrees with the axis of rotation. Each tooth has winding stages adapted for commutation in at least one preselected sequence. The skewed magnetic field, skewed notches and phantom magnetic skews reduce cogging between the rotatable assembly and the stationary assembly as the rotatable assembly rotates while maintaining a back EMF waveform having a maximized flat top width.
