Title: Straw/fodder conversion apparatus
IPC: A23K10/32
Filed: 1982-03-02
Abstract: Straw/fodder conversion apparatus comprising a sealable bin (10) which can receive straw to be heated in an ammonia laden atmosphere, wherein the ammonia atmosphere is fed to the bin from an expansion tank (18) external to the bin, into which ammonia from a liquefied source is allowed to expand and boil as it warms under the influence of the environmental temperature, generating an ammonia atmosphere which expands naturally through a connecting duct (24) into the bin interior. Heating is preferably provided by a fluid circulating system (28) which includes a duct (38) passing through the expansion tank (18) to enable supplementary heating of the ammonia in the tank in cold weather conditions. <IMAGE>

Title: A trawl board
Inventor: HORSFIELD THOMAS
IPC: A01K73/045
Filed: 1982-10-15
Abstract: A trawl board for use with a trawl net has a hollow open end form with a substantially straight rear face 1 and a curved front face 2 both of which have louvres bevelled (as at 5,6,7) to facilitate passage of the board over the sea bed and the disposition and positioning of the board.

Title: Hinge assembly for vehicle sun roof
Inventor: LIEVESLEY JOHN BRIAN
IPC: B60J7/16
Filed: 1983-02-28
Abstract: A vehicle sun roof comprises a frame (2) adapted to be fitted in the roof of a vehicle, a roof panel (1) and a pair of hinge assemblies for hingedly mounting the panel on the frame. The frame (2) consists of two sections (3, 4) adapted to grip a vehicle roof around the edges of an aperture formed therein, the upper section (3) having an arcuate surface (18) on its lower face and a beading (11) of resilient material applied to its upper face.

Title: Electrical switch
Inventor: WACHNIANIN LEON
IPC: H01H13/12
Filed: 1983-05-12
Abstract: A miniature electrical slide action switch is suitable for motor vehicles, for example as a hand brake warning switch. A slide member 4 carries an electrical contact member 16 which passes into a longitudinal slot 24 in the slide member 4 through a slot 22 in an end wall thereof. The portion of the contact member extending outwardly of the slide member provides a seat for a return spring 10 and is provided with a fulcrum edge 20 which defines a pivotal axis for the contact member 16. The portion of the contact member 16 located in the longitudinal slot 24 is biassed radially outwardly against a side wall of a casing 2, in which are exposed one or more first electrical terminal conductors 28. Axial movement of the contact member 16 relative to the slide member 4 is prevented by the fact that the return bias for the slide member 4 is transmitted wholly through the contact member 16. <IMAGE>

Title: Reflex visual approach slope indicator
Inventor: SINCLAIR WILLIAM DONALD
IPC: B64F1/20
Filed: 1983-08-12
Abstract: A sharp-transition visual approach slope indicator for mounting adjacent a runway to indicate to a pilot the correct angle of approach comprises a beam-forming lens (7), a red filter (11) in the focal plane of the lens and a lamp (1) and pair of reflectors (3,21) which illuminate the filter edge. The lens (7) appears red or white according to whether the angle of approach is too low or too high. The lamp reflector (3) has a central parabolic region and a peripheral region (29). These regions generate the central and peripheral parts of the light beam from the lens (7) and determine their relative intensities. Thus the reflex construction enables the polar distribution to be optimised. Furthermore the indicator is shortened and its mass reduced, thereby reducing the danger in the event of a collision. <IMAGE>

Title: Apparatus for measuring light beam characteristics
Inventor: MARGULIS WALTER
IPC: H01L31/08
Filed: 1983-11-18
Abstract: The spatial or temporal characteristic of a beam of light or other electromagnetic radiation or a beam of sub- atomic particles is measured by an array of detectors. The array comprises a layer 1 of photosensitive material on which there are positioned pairs of electrodes 1a, 2a and 1b, 2b etc., with gaps between the electrodes of a pair. The gaps are spaced apart linearly and the material is chosen so that incident light affects current flow between the electrodes defining a gap. Changes in current flow between the individual pairs of electrodes are measured. For measurement of spatial profile the material of layer 1 has a resistivity which varies linearly with the amplitude of incident light. For measurement of temporal profile the beam is split with the split beams being directed on to the array with different angles of incidence and the material is chosen to have a non-linear variation of current with light amplitude. These materials may be, respectively near-intrinsic Si and Ga P or ZnS. <IMAGE>
