Patent GB-2153164-A (GB)
Title: Control circuit for electric fencing
Inventor: MEHTA INDULAL
IPC: H05C1/06
Filed: 1984-01-18
Abstract: The circuit comprises an oscillator Q1, Q2, Q3 energised from a low voltage D.C. supply I and having its output connected to the primary of a transformer T1, and a capacitor C2 connected to the fencing and charged to a high voltage by means of a rectifier W1 connected to the secondary of the transformer T1. The charging time for the capacitor C2 may be about 3 to 4 seconds so that if a load is continuously applied to the fencing, it only receives a shock on initially contacting the fencing. The apparatus may be used to protect domestic goldfish ponds against cats, herons and other predators. <IMAGE>

Patent GB-2157514-A (GB)
Title: Electrical heating circuits
Inventor: SIMPSON BARRY
IPC: H02H5/04
Filed: 1984-04-13
Abstract: A heating conductor 14 for an electric blanket is wound concentrically with a sensing conductor 22 but separated from it by a temperature- sensitive insulating layer 28 to form a composite element 29. In the event of local or general overheat, the insulation of the layer 28 drops significantly and a signal is generated at terminal III of a 3- terminal device 42. Device 42 may be a transistor or a thyristor for example. The device responds to the signal by switching ON so as to provide a virtual short-circuit between its terminals I and II, thus causing open-circuiting of the overcurrent fuse 40. The device 42 is sufficiently sensitive to be switched ON by a short circuit occurring at virtually any position along the element 29, that is, even when the short-circuit occurs so close to one end as to produce a very low potential difference across the fault. In an alternative embodiment (fig. 6, not shown) a heating resistor in series with the thyristor trips the circuit by blowing a thermal fuse. <IMAGE>

Title: Improvements in or relating to cookers
Inventor: HAY GEOFFREY THOMAS
IPC: F24C15/00
Filed: 1985-08-21
Abstract: A floor standing electric cooker is provided comprising a casing (21, 29), a hob (10), an upper oven (12) and a lower fan oven (14) housed in an oven space of the casing above a plinth (16). Convective cooling air (27) enters the plinth (16) and a first part flows through openings (25) in floor (24) through the oven space, discharging through hob opening (33). A second part (30) flows from the rear of the plinth (16) up wall (29). When the lower oven (14) is in use cooling fan (37) coaxial with oven fan (36) provides a forced flow of cool outside air into the oven space. Air is ducted by cover (41) past terminals (40) to fan inlet (38) whereby the terminals (40) are kept cool when the lower oven (14) is on. Despite the compactness of the cooker, the cooling of sidewalls (21) is sufficiently effective for them to butt against kitchen units without an air gap. <IMAGE>

Title: Agricultural product sorting
Inventor: CODDING ELIAS HALE
IPC: B07C5/342
Filed: 1986-01-27
Abstract: Agricultural products such as coffee beans, peanuts and beans are sorted into acceptable and unacceptable categories based on colour characteristics of the products as they descend in a chute (14) from a loading hopper (10) and vibratory feeder (12) through a zone of illumination. Disposed equiangularly about the zone are three optical sensor stations each one having a framing station 22 in which received light from successive portions of the product is directed onto ends of a bundle (26) of optic fibres which conveys the light to an optical divider (32) which divides the light into two colour illumination level components. Photodiodes (48, 54) convert the two colour illumination level components into electrical component level signals. Processing circuits C compare the electrical component level signals, after removal of background illumination level, with reference levels to determine if the colour of the individual ones of the product is within acceptable limits. The background illumination level is periodically sampled by the processing circuitry and the background levels removed from the component level signals are updated if necessary. <IMAGE>

Title: Portable post support
Inventor: BARNES GEORGE
IPC: E01F9/615
Filed: 1986-11-13
Abstract: A portable base 1 which is arranged to rest firmly on the ground and to support a post in an upright position comprises a socket 8 in its upper face 2 for receiving the lower end of the post. The socket wall contains four axially extending grooves 9, 10 each with a right-angled step 11 approximately mid-way along its length for co-operation with a radially projecting pin on the post to form a bayonet coupling for retaining the post in the socket. At the base of the socket 8 there are four integrally formed inwardly projecting resilient tabs 12 which are designed to be depressed by the lower end of the post when the bayonet coupling is engaged so that the tabs will exert an upward force on the post to hold the bayonet coupling in engagement. The base is made of PVC and is moulded in four identical parts 14 which are securely bolted together. The base is made fairly heavy and is intended primarily for use as the base of a temporary signpost which can easily be assembled and disassembled as required. <IMAGE>

Title: Determining the magnetic flux density within a specimen during magnetic particle inspection techniques
Inventor: BONESS KENNETH DUNCAN
IPC: G01N27/84
Filed: 1987-03-03
Abstract: In a method of determining the magnetic flux density within a specimen (2) subjected, during inspection for flaws by magnetic particle techniques, to a steady or slowly varying magnetic field, the specimen (2) is also subjected to a transient primary alternating magnetic field from an exciting coil. This latter induces eddy currents and secondary magnetic fields within the specimen. The impedance of the exciting coil is then measured and hence the incremental permeability of the specimen is derived. From the incremental permeability of the specimen, the required magnetic flux density is determined. Apparatus for use in this method comprises a microprocessor (5) for determining magnetic flux density using data, relating to the incremental permeability and magnetic flux density characteristics of the specimen material, in a data store (6). The method may be used to maintain the magnetic field in the specimen at field strengths of between 40% and 70% of saturation. <IMAGE>

Title: Overlap compensation in digital image generation

IPC: H04N1/06
Filed: 1987-06-18
Abstract: In an apparatus for generating a digital representation of an original image 2 by scanning detectors relative to the image in a plurality of scans, there may be imperfect alignment of the scans resulting in overlaps in the reproduced image. To overcome this the image representative signals are stored, 16, and adjacent scans are compared in a processor 15 to detect correlation. Overlapping signals from one scan are discarded. It is envisaged that relative displacement and rotation of scans may be compensated for, using generally known correlation techniques. Calibration marks may be added to the image (Fig. 6) to provide boundary conditions or starting values. <IMAGE>
