Title: Overhead cable with tension members
IPC: H01B7/18
Filed: 1981-12-04
Abstract: In known overhead telephone cables comprising two individual encased and stranded conductors, each consisting of a plurality of copper wires for the transmission of signals, and steel wires for load bearing purposes, the problem of relatively high susceptibility to corrosion at leakage points in the casing due to water penetration is solved by replacing the steel wires with bundles of stretch-resistant synthetic fibres, e.g. aromatic polyamide fibres, and the tendency of spirally wound synthetic fibres, or bundles of fibres, to shift towards the center of the conductor when the cable is under tension, and thus allow the cable to elongate is prevented by arranging the copper wires and bundles of fibres so that they position themselves mutually. The coherency of the bundles of fibres required for this purpose may be obtained, for example, by stranding or twisting the fibres in the bundle or impregnating the bundle with a resin, preferably colophony.

Title: Enzyme electrode using electrolytic oxygen
IPC: C12M1/40
Filed: 1981-02-20
Abstract: An enzyme electrode based on an oxygen electrode and an oxygen consuming enzyme is described. The oxygen demand of the electrode is satisfied through an electrolytical oxygen production by means of an anode located close to the enzyme and the sensitive surface of the oxygen electrode. The deviation from a reference value, which could be constant or be formed by the signal from an enzymatically passive oxygen electrode, of the oxygen electrode signal, is used to control the electrolysis current in order to keep the oxygen activity in the enzyme electrode constant. The electrolysis current is used as a measure of the concentration of the substrate of the enzyme.

Patent EP-0104865-A3 (EP)
IPC: G07C9/00
Filed: 1983-09-20
Abstract: A code confirmation circuit includes input means com­
prising a number of switches (KI to Kn) each representing a 
different code value. A counter (CT) has a number of outputs 
energisable in sequence from a datum state and each 
representing a different code value. Circuit means intercon­
nect the switches and the outputs of the counter such that 
the operation of a switch having the same code value as the 
energised counter output causes an amplifier (A1) to clock 
the counter (CT) so as to energise the next counter output in 
sequence. Resetting means comprising a second amplifier 
(A2) are responsive to the operation of an incorrect switch to 
cause the counter to be reset. The energisation of the last 
counter output in the sequence indicates the correct sequ­
ence of operation of the switches.

Abstract: An improved method and apparatus for froth flotation 
separation of the components of a slurry, having particular 
utility for the beneficiation of coal by the flotation separation 
of coal particles from impurities associated therewith, such 
as ash and sulfur. In this arrangement, an improved open 
flow, spiral nozzle is positioned above a flotation tank hav­
ing a bath therein, and sprays an input slurry through an 
aeration zone into the surface of the water. The spraying 
operation creates a froth on the water surface in which a 
substantial quantity of particulate matter floats, while other 
components of the slurry sink into the water bath. A skim­
ming arrangement skims the froth the water surface as a 
cleaned or beneficiated product.

Title: Arrangement for the treatment of a moving material web
IPC: F26B3/04
Filed: 1984-05-29
Abstract: Arrangements for the treatment of a moving material web by means of an air flow are used for example in the packaging industry for the drying of packing material in web- shape. In this process the web passes through a chamber provided with inlet and outlet for the air, and at high air velocities the web is affected in an undesirable manner so that an uneven, unstable movement is imparted to it.In the arrangement in accordance with the invention this is avoided by means of a baffle plate (9) placed at an angle in relation to the web between the web (4) and the outlet (8) which causes a partial vacuum which balances the web and gives it a calm and steady movement through the chamber (1).

Abstract: A control system for manipulator apparatus having a ma­
nipulator arm movable in a plurality of axes utilizes resolved 
compliant motion control to improve servo response charac­
teristics. The position and velocity of the manipulator arm are 
controlled using load modeling to account for compliance in 
the arm and to synthesize feedback signals respresenting 
movement of a remote point of the arm to provide a loop band­
width greater than is possible using feedback signals from in­
ner less remote points of the manipulator that are closer to the 
drive points. The feedback signals are derived using predeter­
mined combinations of force related feedback signals from the 
axis drive arrangements and position and velocity feedback 
signals of the manipulator apparatus at points closer to the 
main drive and support structure of the manipulator and before 
certain compliant portions of the manipulator arm. To further 
enhance response and control of the manipulator arm, load 
modeling is also used to provide controlled deceleration be­
fore the manipulator arm is brought to a stop during work op­
eration.

Title: Coin checking apparatus
IPC: G07D5/00
Filed: 1985-11-28
Abstract: The arrival of a coin in a coin checking apparatus is detected by arranging for the coin to hit a member (16). The vibration caused by the impact causes a piezoelectric element (36,36a) to give a transient output signal which is used to switch on electronic circuitry of the coin checking apparatus. The circuitry is normally switched off and thus over a period of time the average power consumption of the coin checking apparatus is low so that it can be satisfactorily run from a battery.
