Title: Manufacturing monocrystalline cast blades of cubic structure
Inventor: ALESSANDRI MARTIAL GERARD
IPC: C30B11/14
Filed: 1982-09-24
Abstract: A method of manufacturing monocrystalline cast blades of cubic structure comprises effecting a directional solidification. A single grain crystal is selected by means of a selection device 1 at the outlet of which a single grain is to be found, of predetermined orientation and having an direction coincident with the vertical. It is arranged that the axis 12 of each portion 8 will be oriented in a direction of the selected crystal. The blades may be cast in a cluster by making a selected grain grow in a common vertical germination column 6, and the solidification front is made to progress continuously from the vertical column 6 up to the portions to be cast (18, fig 2) and along inclined branches 14 stemming from the germinating column 6.

Title: Ladder attachment bracket
Inventor: SMITH SAMUEL DAVID
IPC: E06C7/48
Filed: 1982-10-13
Abstract: A bracket for mounting a cross bar on a ladder is provided for use in pairs. Each bracket comprises a plate having a pair of limbs 10, 11 in right-angled spaced relation for engaging two faces of a rectangular- section ladder stile 16, and a securing bar 12 having members in L-shaped disposition to engage the other two faces of the stile 16 and connect adjustably with the limbs of the plate to secure the bracket to the ladder stile. The plate 10, 11 has an extension 20 to carry the elongate cross bar 17 transversely across the ladder between and extending laterally beyond the brackets. Thus, the bracket can be attached to the ladder stile 16 firstly by placing the limbs 10, 11 of the plate against two faces of the stile, then locating the bar 12, through slots 14 of the limbs 10, 11, and tightening the wing nuts. The slots 14 allow the bar to draw towards the junction of the limbs as it comes into firm engagement with the other two sides of the ladder stile 16. <IMAGE>

Title: Pressure sensor
Inventor: SHORROCKS N M
IPC: G01L9/00
Filed: 1984-02-14
Abstract: A high capacitance piezoelectric pressure sensor in which the shear mode of a thin piezoelectric plate is exploited to eliminate spurious thermal response by the pyroelectric effect. This sensor is comprised of a thin plate of piezoelectric material-e.g. piezoelectric ceramic, the polar axis of which lies in the plane of the plate reinforced by means of two metal electrode plates, one adjacent each face of the piezoelectric plate. A piston is used to convert external hydrostatic pressure to a longitudinal stress and this stress used to provide shear stress in the piezoelectric plate. The plates may be fixed at their periphery. Alternative to this, they may be supported upon a thermally insulating block, a spacer and stop arrangement being provided to limit the longitudinal stress. As further improvement the piezoelectric plate may be assembled from four or more identical segments cut from a single block of material and arranged with alternate segments inverted relative to respective polar axes. In the latter construction polar pyroelectric single crystal material may be used. <IMAGE>
