Title: Thermostatic arrangement
IPC: F24H1/18
Filed: 1972-09-12
Abstract: 1377075 Thermostatic controls for boilers HARFORD-UNICAL Ltd 12 Sept 1972 [16 Sept 1971] 43209/71 Heading F4B In a domestic boiler having a control level thermostat and a high level safety thermostat, the thermostats and other controls are so arranged that a shutdown due to the safety thermostat operating when there is an overshoot on the control thermostat is distinguished from a shutdown due to operation of the safety thermostat after failure of the control thermostat. In one embodiment, Fig. 1, the control thermostat 1 has normally closed contacts in series with the normal burner controller 2, and the safety thermostat has normally closed contacts 4 in series with a flame detector 3 connected to the controller 2. If the control and safety thermostats both operate, the boiler is shutdown normally, but if safety thermostat operates while the control thermostat contacts remain closed, the action is similar to that produced if the flame is not established. In other arrangements, the normally closed control thermostat contacts are connected in series with a change over contact of the safety thermostat, so that if the safety thermostat operates while the control thermostat remains closed a thermal switch or latched relay is operated to light a signal lamp and produce a lock out until a reset pattern is pushed. In an arrangement comprising changeover contacts on the control thermostat 15 and on the safety thermostat 16 are connected in series, Fig. 3, with the normal controller 22, in their normal position, and the normally closed contacts 17 of a latching relay operated by a coil 19 are connected in series with the thermostats. An alarm light 21 bridged by reset button 20 and relay coil 19 are energized by the operation of the safety thermostat 16 while the control thermostat has not operated. The time delay in the relay must be longer than that of the safety thermostats. Other arrangements avoid the necessity for different time lap in the relays and thermostats.

Title: Method and apparatus for monitoring the wear on a rotary drill  bit
IPC: G01N3/58
Filed: 1973-09-25
Abstract: 1394314 Monitoring wear on drill bit TEXACO DEVELOPMENT CORP 25 Sept 1973 44801/73 Heading G1N The wear on a drill bit is monitored by determining the product of the weight on the bit and its revolutions. As shown in Fig. 1, the weight of the drill assembly on a drilling rig is measured by the tension in the line 50 by a transducer 51, converting the tension to hydraulic pressure which is fed through a tubing 7 Fig. 2 to a Bourdon tube 10 positioning the slider 12 of a potentiometer 9. The voltage at 12 is initially balanced by the voltage at a manually adjusted slider 15 of a similar parallel potentiometer 14. When the drill bit is resting on the bottom of the bore hole, its apparent weight is reduced by the weight on the bit, which is measured by the voltage difference between the sliders 12, 15. This voltage signal is converted at 16 to a pulse train 17 of proportional frequency and forms one input to a counter 5. The number of bit revolutions is measured by a tachogenerator 55 whose A.C. output is shaped by unit 4 to produce a square pulse train F of proportional frequency. Each pulse opens counter 5 for a constant time interval to allow the pulses 17 from weight transducer 3 to be counted. The resultant count shown on register 6 is indicative of the wear on the drill bit.

Title: Improvements relating to electromagnetic switches
Inventor: BURKITT FRANK
IPC: H01H50/20
Filed: 1963-11-28
Abstract: 1,083,340. Electromagnetic switches. CONTACTOR SWITCHGEAR Ltd. Nov. 25, 1964 [Nov. 28, 1963], No. 46955/63. Heading H2B. In an electromagnetic contactor whose armature 5 is retained attracted after de-energization of the operating coil 12 by the remanent magnetism of a steel disc 2 in the core 1, the armature may be released mechanically should the contacts weld or the demagnetizing supply fail. The mechanical release mechanism comprises two striker-pins 6, 7 urged into contact with the armature 5 by a light spring 8 and acted on by cams 9, 10, carried by a shaft 10a. When the shaft is rotated anti-clockwise, cam 9 engages pin 6 before cam 10 engages pin 7 and moves it to the left, forcing the edge 11 of armature 5 away from the core so that the armature pivots slightly. If the contacts 15 are not welded together, the separation of the armature from the core is sufficient for its return springs to return it to its normal position. If the contacts 15 are lightly welded together, further rotation of the shaft causes the other pin 7 to separate the armature from the core. If the contacts are strongly welded together however the rotation of the shaft is limited by the co-operation of a step 13 with one of the pins 6, 7. This provision ensures that an isolator connected in the circuit of the contacts and operated by the shaft cannot be operated until the contacts are open.
