Abstract: Described are ferroelectric device film stacks which include a templating or texturing layer or material deposited below a ferroelectric layer, to enable a crystal lattice of the subsequently deposited ferroelectric layer to template off this templating layer and provide a large degree of preferential orientation despite the lack of epitaxial substrates.

Abstract: A computer system manages the allocation of memory to an application program using a dependency tree. The dependency tree informs a memory manager of data inputs, data outputs, and intermediate values associated with execution of the application program. The memory manager allocates a single heap structure within a physical memory. Data associated with each node of the dependency tree is allocated to the heap structure so that data input values are allocated in a contiguous block, and intermediate values are allocated separately. In various examples, as execution of the application program proceeds, the separation of intermediate values from non-intermediate values within the heap reduces memory fragmentation providing improved performance of the computer system as a whole.

Abstract: A stabilising device for stabilising a ladder relative to a structure, the stabilising device comprising a main body having associated therewith a first mount which in use can be mounted to the ladder and a second mount which in use can be mounted to the structure wherein said main body comprises an elongated member said mountings being operatively secured thereto in spaced relation therealong.

Abstract: A ventilation system and method for venting a cockpit of a power boat is disclosed herein. The ventilation system comprises a windshield extending from a foredeck of the powerboat, a cockpit cover at least covering the cockpit and a frame. A cockpit vent comprises a frame defining at least one aperature for introducing ambient air into the cockpit. The frame is disposed between the windshield and cockpit cover and includes a windshield engagement member and a cover engagement member spaced from the windshield engagement member.

Abstract: Phthalocyanines of formula (I) are described wherein M is a metal atom, metal compound or is 2H; one H being bonded to each of the two nitrogen atoms depicted as being bonded to M (positions 29 and 31 shown); R.sub.1 -R.sub.25 may be the same or different and are chosen independently from the following groups: straight or branched chain alkyl containing up to 32 carbon atoms where 1 or more non-adjacent CH.sub.2 groups may be replaced by O and/or a double bond; H; F; and at least one of R.sub.2.3.9.10.16.17.34.24 is chosen from formula (II) wherein Y, X and Z are chosen independently from HO, `O, --O, OR, H, C.sub.1-16 branched or straight chain alkyl or alkoxy; X and Z may also be selected from phenyl groups which may be, independently of each other, substituted with one or more C.sub.1-5 straight or branched chain alkyl groups; R may be C.sub.1-16 branched or straight chain alkyl or alkene wherein 1 or more non-adjacent CH.sub.

Abstract: Phthalocyanines of formula (I) are described, wherein M is a metal atom, metal compound or silicon or a compound of silicon or is 2H; R.sub.1 -R.sub.25 may be the same or different, provided that at least one of R.sub.1 -R.sub.25 has the Formula (II), wherein Y groups are independently H, C.sub.1-3 alkyl, halogen or CN; k=0 or 1; l=1-10; m=0 or 1; n=1-10; p=1-10; q=1-20; r=0 or 1; X may be H, Me, etc . . . Compounds of the above formulae are useful in a broad range of applications, including electrooptical devices, and for use in optical recording media.

Abstract: A hinged gutter guard in the form of an elongated perforated cover plate made of relatively rigid sheet material and equipped along one longitudinal edge with a plurality of hinge straps adapted to be secured to a roof beneath the lower course of shingles thereof. The hinge straps, although permanently attached to the cover plate, are capable of being shifted along the plate to a limited extent to insure proper attachment and operation of the guard.
