Title: False ceiling hanger for inverted T-beams floor - uses threaded rod screwing into web of internally winged U=section clip which grips beam flange
IPC: E04B9/18
Filed: 1978-11-10
Abstract: To suspended floors of precast inverted 'T' beams (1) supporting flanged box section infill panels (3,4), the system is used to hang false ceilings (14) and provides for vertical adjustment. Attachment to the beams is by internally winged 'U' section clips (7) of which the wings (6) engage the top faces of the beam flanges (2). The invert of the clip has a shallow trapezoidal section, incorporating a tapped central hole for a threaded rod hanger (9). Initially the rod (9) is screwed home to bear on the beam soffite, thus causing the clip wings to grip the beam flanges. Once the infill panels (3,4) are placed the clips are secure and thereon may be unscrewed to set the false ceiling at the required level. An end folded strap (11) may be fixed to the base of each rod by means of a nut (10), the folds locating the flanges of a trapezoidal section rail (12) to which the false ceiling (14) is screwed (13).

Abstract: A film-forming oleophilic photopolymerizable composition is formed from a fluid epoxy resin having an epoxy equivalent of less than 350 and a photosensitive reaction product of a water-soluble, photosensitive condensation product of a diazonium compound and an organic condensation agent with an organic coupling agent. The organic coupling agent is selected such that the photosensitive reaction product is soluble in organic solvents but only slightly soluble in water. The photopolymerizable compositions can be used as the photosensitive layer of water-developable negative lithographic plates, such as printing plates. Water-developable negative lighographic plates are also provided in which the photosensitive layer is formed from a layer of the film-forming oleophilic photopolymerizable composition which is deposited on a hydrophilic support from an organic solvent solution. In addition to being water-developable the negative lithographic printing plates of the present invention have high mechanical resistance, long shelf-life and can be used in large production runs to make a great number of copies.

Patent FR-2469484-A1 (FR)
IPC: D03D47/23
Filed: 1979-11-14
Abstract: The thread released at the outlet of the shed is taken up by means of a brush (35) moving in its plane and which is arranged on the path which the weft thread (30) travels. The movement of the brush (35) carries the thread towards a surface (33) which is tangential to the brush and which pinches and retains thread (30). When the thread (30'') leaves the shed in the form of a loop uncoiling, the speed of the brush (35) will be such that the time for covering the path (1') between the point of impact and the surface (33) will be shorter than the time necessary, when the yarn rides over, for withdrawing the surplus length of thread (1).

Title: Small motor permanent magnet rotor - has alternately stacked discs of trapezoidal cross-section magnetic material and permanent magnet discs(BR 27.7.81)
Inventor: SURCHAMP YVON
IPC: H02K1/27
Filed: 1980-01-10
Abstract: The rotor design optimises the structure for a maximum air gap field, reducing the internal impedance and increasing power. The design is based on the use of stacked discs of permanent magnet material (7) alternating with discs of some magnetic material (5,6) the dimensions of the latter being a function of the field it carries. The disc sections are trapezoidal, the two metal types providing complementary shapes to each other. The short edge of the trapezoidal magnetic material is set closest to the motor shaft (1). Alternatively, the axial cross-section of each magnetic material disc increases and decreases periodically w.r.t. the rotor surface such that the sum of the axial section surface of two consecutive discs is constant. The geometrical dimensions of at least one section of the discs are an increasing function of the magnetic induction in their constituent material.
