Title: Wellbore drilling tool
IPC: E21B4/02
Filed: 1980-05-23
Abstract: There is disclosed a drilling tool 10 of the type having a dowhole motor, e.g. turbine 16, 17, and a method of operating the tool in drilling a wellbore.

Title: Vacuum System
IPC: B60T13/52
Filed: 1980-06-11
Abstract: In the operation of a motor vehicle vacuum system e.g. vacuum servo operated brakes, the availability of an adequate vacuum at short notice, particularly when pressure rises in the working chamber when the suction requirements exceed the capacity of the suction pump, is achieved by the provision of a vacuum store chamber 3 which is evacuated simultaneously with the working chamber 2, and which is applied to the working chamber 2 when the pressure rises therein by operation of a non return valve 5. The vacuum is applied in a first stage to the working chamber, and in a second stage simultaneously to the working chamber and the vacuum store chamber by a gas control means, which may be a throttle 4 (Figure 1) or a valve (Figure 3, not shown) operating in parallel with the non return valve 5. In a modification of Figure 1 the vacuum pump 1 may be a pressure pump, and the non return valve 5 is reversed to actuate a pressure system instead of a vacuum system. <IMAGE>

Title: 2-Wire sensor supply circuit
IPC: H03K17/725
Filed: 1981-11-05
Abstract: A rectifying circuit RB1 rectifies AC to energize a sensor element N. A constant voltage circuit R3-R5, VR1, Q2-Q3 provides a constant voltage at node P. A charging circuit R6, Q4 provides a fixed voltage drop to keep capacitor C charged to a given voltage, this capacitor energizing the sensor element N. When the sensor element produces an output, by transistor QA turning on, transistor Q6 in a further charging circuit LED, Q6, D1, Q7, R13 is turned on, and this keeps C charged via D1 to substantially the same voltage as before. Part of the current through Q6 flows through Q7, which fires VRC and thereby increases the current drawn by the circuit. This in turn increases the current through R14, firing SCR1, and producing an increased current on the AC side which indicates that the sensor has sensed the relevant condition. <IMAGE>
