Abstract: ABSTRACT OF THE DISCLOSURE           In the exemplary embodiments of the invention disclosed, thermal neutron decay characteristics of an earth formation, e.g. the thermal neutron decay time constant   and the macroscopic capture cross section  , are measured by detecting indications of the thermal neutron concentration in the formation during a selected set of two different measurement intervals between neutron bursts and forming a ratio of such measurements, as accumulated for an appropriate length of time, from which the measured value of the decay characteristic is derived.  The particular set of measurement intervals used is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic.  Each measurement interval set is used over only a specific range of decay characteristic values for which it has been determined, in accordance with a previously established relationship between the decay characteristic value and the ratio of the thermal neutron concentration measurements for the set.  The measured value of the decay characteristic is then determined from the actual measured value of the ratio for the selected measurement interval set and the previously established relationship for that set. Each measurement interval perferably consists of à plurality of contiguous, discrete time gates whose durations and times of occurrence are adjustable in common by a finite number, e.g. four, of discrete scale factor values F, each corresponding to a specific range of decay characteristic values.

Abstract: ABSTRACT           The invention relates to the combination of a percussion instrument such as a drum and a locking device for preventing unwanted rotation of the headed tension rods used to tension the skin of the drum.  The device has a resilient portion to engage the rod head and an anti-rotation surface-engaging portion connected thereto.  The resilient portion includes a recess, the walls of which extend at least partially through the interior of the device, of a size that the recess can receive the rod head when the resilient portion is press fit over the rod head.  The surface-engaging portion has an edge for engaging a stationary surface of the drum rim, the edge being spaced from the axis of the recess by a distance about equal to the shortest distance from the stationary surface to the rotation axis of the rod.  When the device is press mounted over the rod head and the surface-engaging edge is in contact with the stationary surface of the drum the rod cannot rotate on its own and the drum will remain in tune.

Abstract: CARRIER SUBSCRIBER TELEPHONE OFF-HOOK DETECTOR          by TOM L. BLACKBURN                          ABSTRACT OF DISCLOSURE     A resistor and diode means are electrically connected in series between nodes A and B on the base electrodes of first and second transistors of a differential amplifier.  These nodes A & B are also connected to a source of temperature-compensated load-sensitive refer-ence voltage and to a tap point, respectively, that senses current in the loop of a carrier-serviced subscriber's telephone set.  The base and emitter of a control transistor are also connected to associated nodes A and B.  Conduction of the diode means and control transistor prebiases the latter and reduces the reference voltage during an on-hook condition.  When the handset goes off-hook, the node B voltage rises faster than that on node A for decreasing the conduction rate of the control transistor to indicate an off-hook condition, and eventual-ly cutting off the control transistor prior to the diode means.  This operation of the diode means extends the loop length over which the circuit will detect an off-hook condition.  With the diode means cut off, the second transistors collector voltage biases an FET in the loop for varying the resistance thereof and making the loop current a pre-scribed value for loop lengths that are less than a limiting value.
