Abstract: ABSTRACT An anchor support for supporting a pipeline above the ground has a self-aligning support saddle that allows the pipeline to orient itself on the anchor support during construction to relieve stresses in the pipeline and to allow for variations from nominal pipeline elevation and angulation relative to the ground. The anchor support normally fixes the pipeline's position relative to the ground but also allows relative movement between the support and the pipeline upon occurrence of a seismic disturbance or other disturbance that would cause a dislocation of the pipeline and/or anchor support from  its nominal position.  The self-aligning support saddle, which includes a ball and socket connec-tion for allowing the pipeline to orient itself over the saddle, is fastened to a shiftable subassembly that rests on a stationary base assembly affixed to one or more ground engaging vertical support members.  After the pipeline is aligned, the ball and socket can be permanently interconnected to restrain any further movement of the pipeline relative to the shiftable subassembly. The shiftable subassembly is capable of  moving relative to the base assembly in a direction generally parallel to the longitudinal dimension of the pipeline.  When a differential force is applied between the vertical support members and the pipeline, as can be caused by a seismic disturbance, the shiftable subassembly can move along with the anchor saddle and the pipeline relative to the base assembly, thereby preventing any substantial damage to the pipeline.  A restraining mechanism interconnects the shiftable subassembly with the base assembly to releasably restrain the shiftable subassembly upon application    a differential force of less than a predetermined magnitude.  Upon application of a predetermined differential force, the restraining mechanism releases the shiftable subassembly so that it can move relative to the base assembly.   Once the shiftable subassembly has begun to move relative to the base assembly, the restraining mechanism still applies a differential force opposing the  movement.  After the shiftable subassembly has  moved a predetermined distance relative to the base assembly, an energy absorbing member deceler-ates and stops the shiftable subassembly to prevent it or the remainder of the anchor support from  becoming damaged.

Abstract: COAL LOGGING SYSTEM            Abstract of the Disclosure A borehole logging tool employs two neutron sources of differing energy outputs, two gamma-ray detectors, and a neutron detector in the radioactivity logging of a coal-bearing formation. A first of the gamma-ray detectors measures the gamma rays produced by the formation in response to the higher energy neutron source.  A second of the gamma-ray detectors measures the gamma rays produced by the formation in response to the lower energy neutron source.  The neutron detector measures thermal or epithermal neutrons produced by the formation in response to the neutron sources.  These measurements are selectively transferred to a recording system employing a plurality of energy level discriminators, count rate meters, and comparators.  The recording system, in response to these measurements, provides output signals representative of the carbon, sulfur, ash, and neutron moderating power of the coal in the formation being logged.  The carbon and neutron moderating power provide a means of measuring the energy content of coal.

Abstract: ABSTRACT OF THE DISCLOSURE     To reduce errors in a refractometer caused by temperature effects from changes in the flow rate of fluids passing through the instrument, the flow of heat is adjusted to balance the flow-rate-dependent temperature increases against the flow-rate-dependent temperature decreases that occur with the same change in flow rate in each flow path.  Some of the techniques for adjusting the flow of heat are:  (1) controlling the temperature of the fluid at the inlet of the instrument with one heat exchanger and the temperature of the body of the instrument with another heat exchanger; (2) controlling the tempera-ture of the walls of the instrument with a heating coil; and (3) emitting heat within the flow path from a trans-ducer.

Abstract: TITLE OF THE INVENTION            SAFETY CAP WITH ENERGY ABSORBING SUSPENSION            INVENTOR          JOHN H. KING 4382 Mandalay Drive Lilburn, Georgia  30247 ABSTRACT OF THE DISCLOSURE            A safety cap has an energy absorbing suspension including crown straps for supporting engagement with the crown of a wearer's head connected to elastically deformable, rupturable and controlled plastically deformable portions of connecting means attached to anchor means in the shell of the cap.  The connecting means have end portions adapted to be attached to and wedgingly engage the anchor means.  The shock or impact of a blow against the shell suspended on the resist-ing wearer's head is partially absorbed initially by a wedging action which continues until the end portions are fully seated relative to the anchor means.  Further, loading causes the crown straps to pull against, deform and bend energy absorbing portions of the connecting means into adjoining apertures of predetermined size and shape. Finally, at a predetermined force, the bending moments at opposite ends of the energy absorbing portions exceed the tensile yield strength of the material and causes the portions to rupture.  The failure and plastic deformation thereof is thereafter controlled and limited by allowing them to progressively or successively bottom against control means about the apertures.  An adjust-able and removable headband including a sweatband is attached to and supported by the connecting means.

Abstract: PHN.8608 ABSTRACT:         A matrix printer for characters which are composed of individual dots. The recording elements form at least one group, successive groups being chained in the line direction.          Between successive recording elements within as well as be-tween the groups, each time predetermined row jumps and column jumps are present, so that each group always covers all rows of a character. All recording elements are accommodated in a member which can be driven to and fro along the lines of characters, so that during each movement stroke (in one or both directions) a line of characters is printed. At the beginning of a line, a chaining unit is filled with a start-ing column address and a starting row address and also with a starting character address, the latter being dons to address a line buffer which contains data of a line of cha-racters. In reaction thereto the line buffer supplies a character signal which serves to address a character genera-tor which also receives column addresses and row addresses as further sub-addresses. The chain unit contains data as regards the relevant row jumps and column jumps. Between the displacement of the movable member over-one column dis-tance, the chaining circuit once successively calculates dot data for all recording elements, said data being serially loaded into a dot register. When the  next column position is reached, the dot data are used to activate the recording elements. The character generator comprises at least two sets of characters of different dimensions of the character field, and the chaining unit comprises per character set at least one mode position for translating the column jumps and row jumps of the recording elements into row addresses and column addresses for the character generator. The relevant jumps may be embodied in a counter in the case of regular spacing (for example, the row addresses) and, in the case of irregular spacing, in a read-only memory (for example, the column jumps if a non-integer number of character field is present between successive recording elements).
