Title: Modifying pixel values to improve iterative process for holographic display
Inventor: HILL PHILIP NICHOLAS CUTHBERTSON
IPC: G03H1/02
Filed: 2008-05-16
Abstract: A method of projecting alpha-numeric characters on a screen comprises receiving a frame of alpha-numeric characters (figure 2) defined as intensity varying pixels 101, modifying the pixel values to enhance a subsequent iterative process 102 and modulating a light source to produce an interference signal 103. Thus the alpha-numeric characters can be displayed on a screen and the screen and projector may be placed a long way apart. The iterative process may take the form of a repeated Fourier transform process for a predetermined number of iterations or until a detected error threshold is reached. Modification of the pixels may involve applying a high pass filter to the source image or edge sharpening of the image. The light source may be a laser and the moderator may use phase responsive liquid crystals. Only a part of the display may be used, avoiding using the origin or centre of the display (figure 16).

Title: Window Stay with locking position and easy-clean position
Inventor: DOLMAN TERENCE JAMES
IPC: E05C17/28
Filed: 2008-06-18
Abstract: A stay arrangement 10 has a sash arm 12 and a frame track 18. The track 18 carries two carriages 20, 22 which can slide along the track 18, the first of which 20 can be constrained by a locking arrangement. A pivot linkage 23 connects the sash arm 12 to the carriage members 20, 22 so that the window is movable between a fully open position and a fully closed position, when the first carriage 20 is locked, and an alternative open position by releasing the locking arrangement, and moving at least the first carriage member 20 along the track 18. The alternative open position allows access to the outside face of the window for cleaning. Cam surfaces 68, 70 are provided in the vicinity of the second carriage 22 to engage as the sash arm 12 moves towards the closed position, at least when the first carriage 20 is away from its locked position. The engagement of the cam surfaces 68, 70 acts to drive both carriages 20, 22 along the track 18 as the sash arm 12 continues to move toward the closed position, to return the first carriage 20 to the locked position.

Abstract: 454,510. Carbon papers; stencils. NORMAN, J. E., Zanetic Works, Hallaton Street, Leicester. April 1, 1935, No. 10098. [Class 16] [See also Group XVI] An edging strip serving as handling means for a copying medium such as a carbon paper or stencil comprises a separate member adapted for ready engagement on or disengagement from an edge of the medium, the strip having readily releasable means such as press-fasteners for securing it to the medium. As shown, a carbon paper 3 has one of its edges gripped by a folded strip 4 of leather cloth provided with press-studs 5 which pass through holes in the carbon paper. Prior to applying the strip 4 the copying medium may be reinforced, as for example by tape, or a stiffening substance such as a cellulose composition, or the edge may be folded over before the strip is attached. The edging-strip for the copying medium may be attached to a writing board by gripping the latter and the medium, or by co-operating with fastening means on the board ; similarly, the edging strip may be attached to a part of a duplicating-machine when the medium is a stencil. Instead of leather cloth, the edging strip may be a thin folded metal strip having projections on one part co-operating with apertures in the other part. Where the copying medium is a carbon paper, the edging strip may hold a protective piece of tissue paper thereover.

[Also in Group XXIX] In a liquid supply system in which liquid is pumped from a reservoir through a conduit, a pressure reducing valve is located. in the conduit at a point remote from the delivery end thereof and is controlled in accordance with the pressure at the throat of a venturi located in the conduit on the downstream side of the valve. As shown in Fig. 1, fuel is supplied from a main line 8 through a meter 16, a reducing valve 12 and a venturi 13 to a tank 10. The reducing valve, Fig. 2, comprises two chambers 24, 25, with an opening 27. A cylinder 31 houses a piston 29 with a closure member 28. The piston has an aperture 32 and a bottom closure 34 with apertures 42 communicating with the atmosphere and connecting at 41 with a conduit 21 leading to the venturi 13. A piston 36 slides in the member 34 and has a grooved head 44. The valve is connected to a short conduit 14. The pressure of the liquid flowing through the valve is such that the piston 36 being forced downwardly under the action of a spring 48, lever 49 and pin 51 the head 28 is moved from the opening 27. Opposing this is the pressure in the tube 21 which urges the piston 36 upwardly and when great enough causes the head 44 to engage shoulders 46 allowing the pressure to rise in the piston 29 and so force the piston upwardly so that the member 28 closes the aperture 27 and thus stops flow of liquid. The venturi unit, Fig. 3, comprises a tube 58 in which is a stem 62 having holes 66 and communicating with an enlarged box 67 and an outlet 70 to the conduit 21.
