Abstract: Lift Mast Assembly Abstract This invention relates to an improved visibil-ity free lift mast which eliminates the problems of reduced lift height, upright strength and excessive guide bearing loading.  The lift mast assembly has a fixed upright and a movable upright mounted on the fixed upright and elevationally movable relative thereto. A lower guide bearing is mounted on a lower end portion of the movable upright and an upper and intermediate guide bearing is mounted on an upper end portion of the fixed upright.  The intermediate guide bearing is positioned between the upper and lower guide bearings a preselected distance spaced from the upper guide bearing.  The movable upright is elevationally movable a first preselected distance at which the movable upright is contactable with the intermediate guide bearing and free from contact with the upper guide bearing and a second preselected distance at which the movable upright is free from contact with the intermediate guide bearing and contactable with the upper guide bearing.  Thus an improved visibility lift mast with free lift has been provided which offers maximum lift height for a given upright length, superior upright strength, and sequenced roller loading for improved roller life.  The lift mast assembly is particularly useful in a fork lift truck.

Abstract: ABSTRACT     A double-insulated portable electric tool has a housing with a pistol-grip switch handle portion and a switch cover portion removably secured to the switch handle portion forwardly thereof.  An electric switch is mounted on the back of the cover and is provided with an actuating member.  A trigger is mounted on the front of the cover and is coupled to the switch actuating member.  The switch is accessible only upon removal of the switch cover from the switch  handle; and even unauthorized removal of the trigger will not render the switch accessible.  As a result, the switch may be replaced easily without an inadvertent interference with the double-insulating feature of the tool.

Abstract: ABSTRACT OF THE DISCLOSURE     Process for generating synchronizing signals used for writing and/or reading recorded digital data or recording on an optical data carrier, in which the synchronizing signals are obtained from basic clock signals regenerated in phase with the aid of the determination of the phase shift of a specific pulse relative to the clock signal.          According to a preferred variant, the specific data and the useful information data are coded according to the NRZ code.  The specific data are associated with pulse times not used in the NRZ code for the recording of the invormation data.     The synchronizing signals genrated on the basis of the reading of these flags can then be used for writing during the information data recording phases.

Abstract: ABSTRACT:     For determining the half-cycle durations of the input signal which is presented as a sequence of sampled values, its zero crossings are approximated too by lines which interconnect the from sampled values of different sign on both sides of the zero crossing. The half-cycle duration is derived from the number of sampled values within a period, i.e. between two consecutive zero cross-ings, and from the time intervals at the beginning and end of each half-cycle determined by the intersection of the approximation line with the axis. The time intervals at the beginning and end of each period are corrected for a more accurate determination of the duration and the time intervals during which the values of the individual half-cycle durations are stored, are made to approximate to these half-cycle durations.  The instantaneous frequency of the input signal is determined from the values of the half-cycle durations which have thus been shifted in time by forming the reciprocal.

Abstract: ABSTRACT OF THE DISCLOSURE       Pitch (the faction boiling above 524°C) of low metals content is produced by delayed coking of a heavy hydrocarbon oil with a high metals content.  In a first delayed coking step, the gaseous and liquid phase is removed and sent to a fractionation unit.  The bottoms from the fractionation unit are (a) subjected to a second delayed coking to produce coke which meets electrode grade specifications for metals, or (b) catalytically hydrocracked for conversion of distillate products.  The demetalized pitch produced in the first delayed coking operation is also a valuable product for use as a binder in the production of coke for electro-metallurigical applications.

Abstract: METHOD AND APPARATUS FOR PROVIDING        CALL TRACING SERVICE     Abstract For use with a telephone system having a communications terminal and serving a plurality of station, method and apparatus is disclosed for providing a customer-originated call tracing service on a per call basis. Responsive to a call from a calling station to a called station, a memory dedicated to the called station stores the directory number of the calling station.  An indicator bit associated with the memory designates the stored directory number as that of a "calling" station. Receiving, for example, a nuisance or obscene call, the customer at the called station enters a predetermined access code after the call to send the designated directory number of the calling station as well as the called station directory number to the communications terminal for subsequent follow up by appropriate personnel.  Several calling station directory numbers may be stored in the memory for subsequent display at the called station.  In such case, the called customer may first choose the directory number of the nuisance caller, particularly, when the called customer receives a large number of calls during a relatively short period of time.
