Patent GB-2021961-A (GB)
Title: Controllable kite
IPC: A63H27/08
Filed: 1979-05-18
Abstract: A kite is controllable by a control cord (17) connected to control (6) on the kite for moving a bridle loop (9) which repositions the location of the connection of the cord (17) to the bridle loop (9) with relation to the kite. This movement of the bridle loop (9) alters the flying attitude of the kite. The control (6) includes a camming mechanism for moving the bridle loop (9) in two steps between different positions through a control arm (7). The camming mechanism is actuated by a spring for the first step when tension on the control cord (17) is released and by the force of the wind on the kite for the second step when the necessary tension is placed back in the control cord (17), the force of the wind also replacing energy in the spring for the next desired movement of the bridle loop (9). <IMAGE>

Title: Process for the Preparation of Water-Soluble Phthalocyanine Dyestuffs
IPC: C09B62/517
Filed: 1979-06-04
Abstract: The preparation of water-soluble phthalocyanine dyestuffs by reacting a phthalocyanine sulphochloride with a water-soluble aromatic amine in the presence of a tertiary amine catalyst, especially pyridine, is known. The use of pyridine, however, involves considerable problems because of its toxic properties and unpleasant smell. The present invention provides a process for preparing a water-soluble phthalocyanine dyestuff, which comprises reacting a phthalocyanine compound, which contains one or more sulphonic acid chloride groups and which may contain one or more sulpho groups, with (a) a primary or secondary amine which contains one or more  beta -substituted ethylsulphonyl groups or one or more vinylsulphonyl groups and, optionally, (b) a primary or secondary amine of the aliphatic, heterocyclic or aromatic series, in the presence of a pyridine sulphonic acid or a pyridine carboxylic acid. The reaction is preferably carried out in the presence of nicotinic acid (pyridine-3- carboxylic acid).

Title: Electrical connector
IPC: H01R33/955
Filed: 1980-03-17
Abstract: An electrical connector, e.g. a lampholder, has its output terminals 16 disconnected from the supply when no load, e.g. a lamp, is connected.

Title: Fuel injection pump
IPC: F02M59/48
Filed: 1981-02-27
Abstract: A fuel injection pump has a plunger 24 adapted to be reciprocated in a barrel 23 so as to compress fuel and to deliver it until the fuel pressurising chamber 23a in the barrel 23 is connected to a fuel relief port 25 formed in the wall of the barrel by a passage 26 formed in the plunger. The rate of delivery of pressurised fuel is changed by varying the timing at which the fuel pressurising chamber 23a is brought into communication with the fuel relief port which is effected by rotating the plunger 24 in relation to the barrel 23. To this end the plunger is provided with a projection 29b which engages a longitudinal groove 28 formed in a plunger rotating member 27 extending around the plunger in such a manner that the projection may slide in the groove in the axial direction of the plunger, but that relative rotation of the plunger and the plunger rotating member is prevented. <IMAGE>

Title: Measuring potential difference
Inventor: FARRER WALTER
IPC: G01R19/10
Filed: 1982-11-05
Abstract: The invention describes a two part multiplexed measurement system capable of measuring voltages between any two selected points 1-n within a power system by differencing currents produced by the voltages at those points via resistors R1-Rn into an amplifier system A1, A2 which inherently reproduces a scaled replica V02 of the voltage waveform between the two points selected but at a safe voltage with respect to safety earth. The arrangement of diode pairs D, D' in the two part system shown is such that when the interconnecting plug at XX' between the two parts of the system is disconnected no conductor of the plug or socket thus exposed has a voltage greater than one volt with respect to safety earth. Furthermore shorting of any conductor to any other at the exposed plug and socket cannot cause damage or malfunction to the power system or the monitoring equipment. <IMAGE>
