Patent GB-2087972-A (GB)
Title: Improved window stay
IPC: E05D15/46
Filed: 1981-11-10
Abstract: The invention concerns window stays having at least two arms (5, 6) pivotally connecting two mounting plates (1, 3) for respective mounting on a fixed frame and sash, the pivot points (7) may be friction rivets. In the stay there is a support and stop plate (13) mounted adjacent one pivot and having an arcuate rib (18) concentric with the pivot but spaced radially so that a land is engaged by the arm (5) to support the loads on movement of the arm. A block (16) provides a stop or abutment limiting movement of and supporting the stay arm (5) in the extreme unfolded position. In another embodiment, the support plate has an extension with ribs and lands engaged by the underside of the second longer arm of the stay and the stop is of a different form. The support plate is a plastics moulding. Improved load support, guiding and control with reduced stress on the pivot joints are obtained by the arrangement of the lands and the principle may be applied to a wide range of stays of this kind. <IMAGE>

Title: Domestic tumble drier
Inventor: BARNISH PHILIP
IPC: D06F58/50
Filed: 1982-10-25
Abstract: In a tumble drier having a rotatable laundry drum 5 arranged in a cabinet 1, both the wall 3 of the cabinet and the end 6 of the drum are protected from direct heating by heating elements 15 by a baffle plate 12 and an annular shield 27 respectively.

Title: Frequency controlled excitation of a gas discharge lamp
Inventor: KOEHNE DR RAINER
IPC: H05B41/285
Filed: 1982-12-01
Abstract: An electric lighting system produces light by feeding an electric tension of high frequency generated in an oscillator (21) having a transformer (24) connected to electrodes of a gas discharge lamp (20). Thereby the gas in this lamp becomes ionized, emits light and exhibits plasma resonances. The frequency of the electric tension is kept on a resonance frequency of the ionized gas by using the operating gas discharge lamp and the secondary winding (27) of the transformer as a resonant tank circuit which determines the frequency of the oscillation. The oscillator operates at either a higher or lower frequency than the plasma resonance before the lamp starts. This higher or lower frequency is determined either by the saturation of the core (K) or by the inductance and stray capacitance of the primary winding (25) of the transformer. The transformer core has an air gap calculated so that the oscillator frequency may shift in the ratio of 1:4. The oscillator frequency is between 10 KHz and 1 MHz. <IMAGE>

Title: Imaging system
Inventor: LACINY RICHARD WENCESLAS
IPC: G02B23/14
Filed: 1984-10-25
Abstract: In an imaging system suitable for example for use as a firearm night sight a primary object viewable from a viewing position (10) is formed by objective optics (17) and an image intensifier tube output face (11). A secondary object 14 is formed by edgewise illumination of a glass plate (15), the plate (15) carrying a diffusion graticule pattern. Both objects are formed in monochromatic light at chromatically separate wavelengths. A glass plate (18) has a dichroic surface (19) transmissive to the wavelength of light from the primary object (11) but reflective to that from the secondary object (14). The lengths from the primary object to the dichroic surface (Z) and from the secondary object to the dichroic surface (22) are arranged to be optically equal, so that a virtual image of the secondary object is formed at the place of the primary object. The invention provides a correctly focussed secondary image without optical components close to the intensifier output face or off axis image projection. <IMAGE>
