Title: Method of Classifying Underwater Objects
IPC: G01N29/12
Filed: 1981-10-14
Abstract: Underwater objects are classified by directing upon them from a surface vessel 10 a beam of sound which excites a located object 19 to resonance. Apparatus in the vessel receives the resulting echo signal and derives from it a spectrum of the received frequencies.

Title: Diamond-like material
IPC: C09K3/14
Filed: 1982-05-19
Abstract: A grinding and polishing material showing diamond-like characteristics is formed by depositing a layer of hard carbon onto a substrate, such as glass or stainless steel, in a glow discharge system. The substrate is chosen to give a weak bond to the carbon layer and may be flexible to assist in removing the carbon layer. As the layer thickness increases on a glass substrate the layer spontaneously breaks into small platelets on exposure to air. These platelets can be used as formed or crushed to form a powder. Hard carbon grown in a glow discharge system.

Title: Data logging device
Inventor: PONTEFRACT RONALD MATTERSON
IPC: G06F3/023
Filed: 1982-08-31
Abstract: To record data relating to merchandise items which are to be ordered a salesman locates a sheet (5), containing a list of merchandise items, between two columns of light- emitting diodes (6). At the start of entry of an order, the top left-hand LED is illuminated under the control of a central processor unit, which simultaneously addresses a main memory storage location corresponding to the item alongside that LED. Data, such as quantity required, can then be keyed into that storage location, which already contains an identification code for that item. The salesman then operates a key which causes the CPU to scan through the LEDs, and the storage locations, in turn, until the next required item on the sheet is reached. Data relating to that item is then keyed-in. At the end of each day, the salesman couples a transducer to a public telephone and transmits the data to a computer at his base. Instead of individual sheets (5) the items may be listed in a book, detection of which page is in use being by means of a light sensor receiving ambient light therethrough; a second sensor receiving the ambient light directly and a comparator are also provided. <IMAGE>

Patent GB-2171798-A (GB)
Title: Condensation indicator
Inventor: DADACHANJI FALI MINOCHER
IPC: G01N27/22
Filed: 1985-02-22
Abstract: Apparatus for detecting condensation on a surface comprises an electrically insulating, moisture impermeable resilient membrane 16 having a first surface for engagement with a surface to be tested and having, on its opposite surface, a humidity sensitive membrane 18. Electrodes in contact with membrane 18 are connected with circuitry for sensing the electrical resistance or capacitance between the electrodes. The condensation of moisture on the surface to be tested is necessarily accompanied by condensation on the membranes 16 and 18 and thus by a drop in the electrical impedance between the electrodes, and this drop is used by the circuitry as an indication of the occurrence of condensation. When the impedance changes by a predetermined degree or in a predetermined manner indicative of the formation of condensation, electrically operated means in a housing (22) cause a visual indicator such as a reset button 24 to be moved from a retracted position to an outwardly extended position, and the power supply is simultaneously disconnected. <IMAGE>

Title: Deburring machine
Inventor: WHARTON JOHN
IPC: B24B23/00
Filed: 1985-11-05
Abstract: A deburring machine for deburring the edges of sheet material comprises a brush (30) mounted for rotation within a housing (48), a slot (66) being provided in the housing extending transversely to the axis of rotation of the brush, whereby, in use, a sheet of material to be deburred can be passed through the slot to contact the rotating brush.
