Abstract: ABSTRACT          A photocomposition machine stores a plurality of pre-determined type optically accessible  characters with a film for recording selected type characters.  A controllable flash oper-ates  with the character storage to expose the film with images of selected characters.  There is also provided a lens system which is controlled as a function of point size values selected  by the operator.  The  control system recognizes point size changes enter-ed by the operator and determines the direction and number of steps to move the lenses in order to provide a magnification cor-responding to the new point size.  The system includes a memory with related input and output devices.  The memory stores data representing the selected point size value.

Abstract: ABSTRACT OF THE DISCLOSURE         Circuitry is provided for establishing the points in time at which radiation is detected following each neutron burst in pulsed neutron logging.  A signal indicative of the arithmetic mean is generated from which the macroscopic thermal neutron capture cross section of the formation of interest surrounding the borehole is computed.  In one embodiment, an indeterminate number of gates provides a means of establishing the point in time of each pulse indicative of detected radiation.          In another embodiment, only a predetermined number of such gates are used.  In yet another embodiment, a weighting factor is applied to pulses occurring either before or after the arithmetic mean such that the number of pulses before the arithmetic mean are a multiple  of the number occurring after such time.

Abstract: ABSTRACT OF THE DISCLOSURE        In an automatic conveyor system, a plurality of independently operable carrier or transport structures are interconnected in closed loop configuration. Each carrier includes plural sheets of overlapping slates, each supported by a carriage which allows the slat to pivot for differ-ential vertical flight level movement and tilting to either side for deposition of articles onto selected receiving stations. A plurality of carriages and slats form an independently operable unit to complement the article size structure with one of the slat supporting carriages in each unit having actuating elements in the form of a horizontal arm to each side with a roller which can be deflected for titling.  The single titling of this arm causes all of the associated slats in that unit to tilt in uni??n as a result of their overlapping nature.

Abstract: HYDRAULIC ANGLING MECHANISM FOR DISC HARROW GANGS    ABSTRACT OF THE DISCLOSURE           Hydraulic mechanism for varying the angular relationship between a pair of adjacent end-connected disc harrow gangs which uses the same power source that ordin-arily is employed for raising and lowering the harrow frame structure as a power source to actuate the gang angling mechanism.  A bell crank lever mechanism embodying a pivot shaft, trailing wheel axle arms, and a crank arm, has the latter arm connected to the power source so that when the crank arm is swung in opposite fore and aft directions, the frame structure is raised or lowered.  The gang angling mechanism embodies floating links which are connected at one end to the crank arm and which pass slidingly through the pivotal juncture between the end-connected gangs, together with removable abutment members which, when applied to the floating links in the vicinity of such junctures, engages the latter when the power source is actuated in one direc-tion or the other and forces the juncture in a direction either to increase or decrease the angular gang relationship, depending upon whether the abutment members are applied forwardly or rearwardly of the juncture.

Abstract: TRACTOR-MOUNTED CARGO-TRAILER BRAKE CONTROL SYSTEM  Abstract of the Disclosure Disclosed is a positive-pressure air brake system for a highway tractor and trailer combination in which the conventional mode of tractor-to-tractor control line connection is avoided and supplanted by a sub-system in which the trailer control line pressures are developed from the tractor supply line rather than its control line through a valve assembly which responds to tractor control line pressures in relay fashion to dispense brake-operating pressures to the control line of the trailer. This valve assembly is further disclosed as having mechanism for sensing differences in the pressure of the tractor and the trailer control lines, e.g., a difference resulting from the rupture of the trailer control line, to close off the air supply to the trailer and thus bring about emergency application of the trailer brakes without any material loss of pressure in either the supply or control lines of the tractor brake system.
