Title: Use of adhesives for assembling fabric lamp shades - using coatings or tapes to anchor fabrics to wire frames
IPC: F21V1/26
Filed: 1975-04-30
Abstract: Fabrication of lampshades uses adhesive coatings or (double sided) adhesive tapes to secure pieces of fabric to a wire frame. The fabrics are draped over the frame and held taut by tie tapes or elastic while adhesives on the perimeter wires at the top and bottom of the frame set to anchor the fabrics. Surplus fabric beyond the frame perimeters is then cut away. Tapes are used to secure doubled back hems or to attach linings through spaces in the framework to an external cover. Method is quicker than traditional stitching techniques for securing segments of fabric, does not require skilled labour. The wire frames are pref. precoated with an epoxy, polyurethane or acrylic resin varnhis or with polyamide (RTM - 'Rilsan'). The fabrics pieces may be cut on a bias so as to support elastic tension while stretched over the frame.

Title: Lock mechanism for different lock types - has stepped spring loaded plungers aligned positively with lock pins
IPC: E05B27/08
Filed: 1975-05-26
Abstract: The locking mechanism can be used in lcoks for different purposes such as padlocks, mortice and motor vehicle door locks. The lock mechanism has no play between the guiding bores and lock pins and plungers no matter what their relative positions. This arrangement ensures that the key can be withdrawn only when the lock is positively locked and not at any angular position. Each plunger (8) is a stepped cylinder whose end with larger diameter faces the cylindrical pin (11) whose diameter is equal to the plunger larger end diameter. The axes of all pins and plungers coincide at a certain angular relative position of the housing opening.

Title: LF static DC convertor - has auxiliary low power oscillator and varying width chopper circuit using sawtooth waveform
Inventor: LOREC GERARD
IPC: H02M7/538
Filed: 1975-08-04
Abstract: The static convertor providing a low frequency A.C. output from a D.C. supply using light transformers.

Title: Electromagnetic braking reduction in electrical machines - uses straight or epicyclic gear trains to move stator in same sense as armature
IPC: H02K23/60
Filed: 1975-12-19
Abstract: The mechanical system reduces electromagnetic braking due to the reaction the armature in the airgap of all known types of electrical generating machines. The braking is reduced to a value greater than the secondary losses. To this end, the stator is moved in the same sense of rotation as the armature whilst maintaining the relative speed to each other. The mechanical couple of the stator is constantly opposed to that of the armature reaction. Gear trains comprised of pinions (16, 17) and toothed wheels permit the maintenance of this relative speed. They also permit the application of the stator mechanical couple on the armature axis. Two types of gear train are used one being direct and the other being epicycloidal.

Title: Homogenising of the temperature of hot metal slabs - by means of a magnetic field
Inventor: EYGLUNENT BERNARD
IPC: B21B45/00
Filed: 1976-11-25
Abstract: Metal products destined for rolling after emerging at elevated temperatures from a reheating furnace are treated before rolling so that they are temperature homogenised throughout.
