A compass comprising optical means (30, 60, 90) arranged to give an image of a directionally relevant portion of a compass scale (26) which image is superimposed directly upon a view viewed through a viewfinder (31, 61, 91) so as that all the scale degree marks visible in the viewfinder accurately represent real angles to enable a bearing or bearings to be taken on any object or objects visible in...

A display device having a display array of mxn display elements driven by a static shift register having mxn stages respectively corresponding to row and column designations of the display elements. The column lines of the display element array are driven by a first output of the m stages. At the same time, pixel data are supplied to the shift register in accordance with a binary level of an exter...

An improved polyurethane orthopaedic cast bandage is disclosed. The bandage is a polyurethane prepolymer coated on an open-weave, fibrous substrate. The prepolymer contains dimorpholinodiethylether as a catalyst which gives the cast bandage increased shelf stability and excellent set time.

A Stirling cycle heat engine, specially suitable for use in environments subject to acceleration or large temperature variations, including a free and reciprocating displacer piston fitted with a non-contact device which acts with increasing force to oppose further movement whenever the piston overshoots desired limits of its movement. The device may include a magnet which is carried by the piston...

The invention relates to a vacuum sizing (20) for cooling and sizing plastic extrusions immediately downstream of the extrusion die (22). The device (20) includes a plurality of pairs (32) of upper and lower sizing elements (34) and (36) which are clamped between upper and lower backing members (20) and (30). The elements (34) and (36) are shaped to define a passageway (26) through the sizing devi...

An electric toaster having a bread carriage which is movable from a rest position to a toasting position at the beginning of a toasting cycle. When moved to the toasting position, the carriage closes a switch which energises heating means. A voltage is then supplied to a power supply unit for a control circuit containing an oscillator (0) and a counter (C). The oscillator generates a sequence of p...

A tape cassette for use with a video tape recorder has conventional tape guiding and braking elements within its housing, including a pair of spaced guide pins for the tape adjacent each reel and a resilient strip that acts on the tape between the spaced guide pins and normally tends to deflect the tape from a straight path between the spaced guide pins for braking the tape when the cassette is no...

Rounded quartz sand particles (22) are each enclosed in a hardenable resin skin (23) which is integrated with the skins on adjacent particles and which creates a binding of the particles to a primed base (20, 21). A significant fraction of the particles may be remote from the base and only integrated with adjacent particles so that a contoured or embossed effect is created to provide a supplementa...

An anti-cancer device having an anti-cancer drug and a blood coagulation factor fixed to a structure. This anti-cancer device is used in transcatheter arterial embolization and needle therapy with advantage and slowly releases the anti-cancer drug over an extended period by staying in the cancer tissue and its nearby area.

A photodiode array imager (50) is described which utilizes polysilicon isolation in place of the normal field implant and field oxide isolation techniques for the puroose of reducing peripheral leakage current. A polysilicon layer 54 is utilized to isolate the sensor structure. This polysilicon layer is grown over a thin gate oxide (52) which has received a threshold enhancement implant with low v...
