Abstract: A display including an electroluminescent layer, a liquid crystal layer, a barrier layer arranged between the electroluminescent layer and the liquid crystal layer to restrict migration of liquid crystal from the liquid crystal layer to the electroluminescent layer, and a first electrode and a second electrode arranged such that the electroluminescent layer and the liquid crystal layer are disposed between the first and second electrodes and arranged to apply an electric field across both the electroluminescent layer and the liquid crystal layer.

Abstract: An electroluminescent display comprising a mask defining the information to be displayed and an electroluminescent (EL) backlight. The mask compress a layer (13) of physically-stabilized liquid crystal switchable to define the information to be displayed mounted in front of an EL layer (16) of the backlight. At least one pair of electrodes (12, 20) are arranged to generate, in use, an electric field across both the EL layer (16) and the LC layer (13). A barrier layer (15) is provided between the LC layer (13) and the EL layer (16) that restricts migration of liquid crystal from the LC layer (13) to the EL layer (16).

Abstract: An electroluminescent display comprising a mask (13) defining the information to be displayed mounted in front of an electroluminescent (EL) material backlight (16). The mask (13) comprises a layer of liquid crystal vesticles (14) encapsulated in a curable polymer matrix (15), where the polymer chains of the polymer matrix (15) have been cross-linked by exposure to radiation. Preferably the polymer matrix is a UV curable polyurethane. The invention also concerns a method of making such a display.

Abstract: An electroluminescent display of the type having a switchable electroluminescent (EL) material backlight mounted behind a mask defining the information to be displayed. The mask is constructed as a layer of physically-stabilised Liquid Crystal (LC) material switchable to define the information to be displayed.

Abstract: An electroluminescent display of the type having a switchable electroluminescent (EL) material backlight (16) mounted behind a mask (13) defining the information to be displayed, in which display the mask is constructed as a layer of physically-stabilised Liquid Crystal (LC) material (14) switchable to define the information to be displayed; and the LC mask and the EL backlight are constructed as a single entity. The LC mask may be directly formed on the EL backlight, or there may be an insulating interlayer (10) between LC mask and EL backlight. The LC mask and EL backlight may be held between a common pair of electrodes (11, 20).

Abstract: A hitch apparatus for connection between a tractor and a trailing implement such as a cutter includes a hitch arm at one end of the apparatus extending forwardly and pivotal so as to extend either inwardly or outwardly thus offsetting the apparatus across the rear of the tractor. The apparatus includes the draw bar hitch at the rear spaced across from the hitch arm for attachment to the cutter so that the cutter is offset to one side of the tractor. Two gear boxes and a drive shaft provide connection from the PTO of the tractor to the drive input of the cutter. The offset hitch apparatus allows the cutter to run in a ditch while the tractor remains on level ground.

Abstract: A mechanism for adjusting the height of a frame of an agricultural implement relative to a groundsurface is described. A parallelogram frame is provided which includes a frame mounted member and a wheel mounting member parallel to the frame mounted member. The frame mounted member is secured in substantially vertical orientation to an end of a transverse support member of the frame of the agricultural implement. A stub axle is secured substantially perpendicularly to a face of the wheel mounting member remote from the transverse support member with a ground engaging wheel rotatably mounted on the stub axle. An expandable jack is mounted to the top of the transverse support member. Upon expansion of the jack a force is exerted upon an upper connecting member causing the parallelogram frame to pivot until a first end of the upper connecting member to which the end of the transverse support member is attached is raised relative to a second end of upper connecting member.
