ELECTROSTATIC DISCHARGE DEVICE
First Claim
1. A static electricity discharge device combining an electrical resistor which has two points of electrical connection to it and means of mechanically attaching the said resistor to a persons finger so that the said resistor and the said means of attaching form a unit which can be worn in the manner of a jewellery ring and the said means of attaching including an insulated plastic housing in which the said resistor is secured and means of making an electrical connection between one of the said two points of electrical connection and the said finger, and an electrode which is electrically connected to the other of the said two points of electrical connection, and the said electrode is insulated electrically from the said means of making an electrical connection, and the said electrode is mounted on the said plastic housing and facing away from the said finger and positioned so that the said person can extend the said finger toward an electrical conductor surface and cause the said electrode to make electrical contact with this surface thus discharging the said persons electrostatic charge through the said resistor at a controlled rate, and also mounted within the said plastic housing a lamp means of indicating flow of electrical current through the said resistor and the said lamp means being connected electrically in series with the said resistor.

Abstract
A device which enables the user to dissipate an electrostatic charge, such as is picked up from walking on a rug, by controlling the rate of discharge through a resistor which is mounted within the device, and the device is worn on the user'"'"''"'"'s finger as a ring and which is thus kept conveniently available, and the device incorporates an indicator lamp which gives a visual indication of the charge dissipation.
