Title: Conveying bales from a storage to a combustion system
Inventor: KNUDSEN JOHN ROBERT
IPC: F23M11/02
Filed: 1988-01-27
Abstract: A plant for conveying bales from a storage to a combustion system (2) consists principally of three elements, namely a crane (3), conveying means and a firing device (5). First the bales are provided in well-defined position in the storage and are gripped by the crane (3) which is controlled for orientating the bales correct in relation to a distribution device (10) which is a part of the conveying means. The distribution device (10) comprises two cylinder/piston assemblies (14, 20) for aligning and displacing of the bales, respectively. The bales are conveyed onto transporting means (11) forming another part of the conveying means, and are conveyed to the firing device (5). The placing of the bales are monitored by sensors (26,28,29,30,31). The signals from these sensors are used to control the rate of conveying so that bales always will be present in an uninterrupted row ahead of the firing device (5). The firing device is provided with security gates (41,42,43) which may be closed to prevent back firing on receipt of signals from at least one temperature sensor (39,40). Furthermore, the firing device comprises spring biased plates firmly surrounding the bales and preventing back firing and false airfeed, and has a flexible connection with the combustion system (2). <IMAGE>

Title: Crop harvesting apparatus and methods
Inventor: KLINNER WILFRED ERWIN
IPC: A01D41/06
Filed: 1988-02-22
Abstract: Apparatus for harvesting crop comprises a rotor 11 mounted on a mobile frame 12 and carries a succession of transverse combs 14 each formed of an array of outwardly projecting teeth 15 transverse to the direction of movement of the apparatus through the crop. Each tooth 15 is pointed with side edges diverging away from the distal tip of the tooth. The rotor rotates in the overshot mode and the combs intrude into the crop and gather crop stems between adjacent pairs of teeth and detach grain and grain heads, or other required crop parts, by rubbing or breaking the parts free from the stems. The junction of adjacent teeth 15 preferably has an enlarged aperture 21 to assist stripping and to allow withdrawal of stripped stems. In other arrangements the teeth may be replaced by a brush-like structure or by rods or other crop engaging elements, backed by plain transverse ribs for collecting and conveying detached crop parts. <IMAGE>

Title: Filter for waste water
Inventor: FROUD DAVID
IPC: B01D35/10
Filed: 1988-06-04
Abstract: Filamental (brush-like) elements made of stainless steel and synthetic fibre are suspended in effluent to provide filtration either on their own or in conjunction with another filter. The elements may be suspended from a grid and filter the influent to a treatment tank, or they are suspended under a foam, mesh, gravel, wedge wire or other type of upward flow filter, to act as a coarse preliminary filter. The elements can be fitted into existing clarifying tanks at sewage treatment works and will reduce the amount of suspended solids in the final effluent.

Title: Thermally-responsive controls
Inventor: BLACKBURN ARTHUR MALCOLM
IPC: H01H37/76
Filed: 1991-03-06
Abstract: A thermally-responsive control for the heating element (7) of a liquid heating vessel has a thermally-deformable member (2) urging a leaf spring (3) into electrical contact with a power supply terminal (6) of the control and a power supply terminal (8) of the heating element for supplying electrical energy to the heating element. The thermally-deformable member (2) is in close thermal contact with the heating element (7) so that in response to a predetermined heating element overtemperature condition the thermally-deformable member (2) will collapse thereby breaking the connection made by the leaf spring (3) between the terminals (6), (8) of the control and the heating element. In a four point disconnection arrangement, collapse of the thermally-deformable member (2) breaks contacts at live and neutral terminals (6) of the control and at live and neutral terminals (8) of the heating element (7). <IMAGE>

Patent GB-2265060-A (GB)
Title: Doppler velocity measurement
Inventor: STEWART NORMAN ARCHIBALD
IPC: G01S13/526
Filed: 1992-03-04
Abstract: In a radar, lidar or sonar receiver there is a need to detect slowly moving objects moving towards the radar in order to ascertain whether these objects are a true target of a non-flying target. The radar received data 1 is fed to a set of Doppler filters 2. The output of each filter is coupled to a comparator 3 which is adapted to determine the identity of the filter producing the largest Doppler level or value. The comparator is further adapted to produce a signal having a logic high value only if the identified filter is the zero-Doppler filter; otherwise the comparator produces a logic low level. The output of the comparator is coupled to a moving window integrator 4 having the plurality of registers, and if a certain number of these registers contain a high value, an output signal is produced by a threshold detector 5 indicative of the identification of a stationary or slowly moving object. This may be used by inhibit circuit 6 to prevent display of these objects. The invention is stated to enable objects stationary with respect to the radar, moving slowly, or moving otherwise to be distinguished. <IMAGE>

IPC: H03L7/197
Filed: 1992-05-30
Abstract: First (Fr(High)) and second (Fv(High)) signals are generated at first and second frequencies respectively, each of which is substantially higher than a desired reference frequency (Fr). The frequency of said generated first signal (Fv(High)) is reduced (34) to a frequency (Fr) substantially identical to reference frequency signal (Fr), wherein the generation of said reduced frequency (Fr) commences within a tolerance of a cycle 1 DIVIDED Fr(High) of said generated first frequency. At a time in the vicinity of a transition of said first generated signal at the desired reference frequency (Fr) and outside the tolerance 1 DIVIDED Fr(High)) thereof, said generated second signal (Fv(High)) is reduced (36) in frequency to a third frequency (Fv) almost identical to said desired reference signal (Fr).. Generation of said signal at said third frequency (Fv) commences within a tolerance of a cycle 1 DIVIDED Fr(High)) of said second signal (Fv(High)) and substantially almost in phase with the reduced frequency (Fr(out)) of said generated first signal. The frequency of one of said generated frequency signals (Fr, Fv) is adjusted, in a predicted manner according to said known phase relation, at subsequent transitions thereof so that said adjusted generated frequency signal converges to said desired reference frequency of the other generated frequency signal (Fr), and the output signal is at the desired output, frequency Fout = NFv=Nfr. <IMAGE>
