Abstract: ABSTRACT    A reach mechanism for use on a material handling device having a load support carriage such as an industrial lift truck and a load carrier.  The reach mechanism has a rear mount attachable to the carriage, a front mount for supporting lift forks or the like, and an extensible linkage for longitudinal projection and retraction of the front mount relative to the rear mount.  The linkage includes two laterally spaced set of links, each set having a first pair of upper and lower links pivoted at the lower ends thereof to the rear mount at spaced points and a second pair of upper and lower links pivoted at the lower ends thereof to the front mount at spaced points. The upper end of each of the first and second pair upper links are pivotally connected to the upper end of the second and first pair lower links respectively.  Hydraulic power rams actuate the links to project and retract the front mount.  At least one upper link is constructed in at least two pieces for articulation thereof between its upper and lower ends about a pivot connection intermediate the ends. The intermediate pivot connection is controlled so as to move through a predetermined path of travel which varies the effective length of the one upper link to cause the minimization of the non-travel transverse and/or tilting movement of the front mount.

Title: Hydraulic binders and building elements formed of non- traditional materials
Inventor: BERETKA JULIUS
IPC: C04B11/26
Filed: 1987-12-09
Granted: 1991-01-22
Abstract: ABSTRACT        HYDRAULIC BINDERS AND BUILDING ELEMENTS          FORMED OF NON-TRADITIONAL MATERIALS     A process is disclosed for the formation of hydraulic binders and building elements comprising from 70% ettringite and up to 30% calcium silicate hydrates.          Ettringite is a very strong mineral and the product may be at least the equal in terms of mechanical properties of Portland cement while not suffering shrinkage and expansion problems.  The process comprises mixing powdered source materials of reactive CaSO4, CaO and Al2O3 with or without SiO3 with or without SiO2 and hydrating the intimate mixture at a ratio in the range of 1 part powdered source materials to 0.35-1 part water.  Most conveniently, impure source material such as industrial by-products are used as they have been found to catalyse the hydration reaction.          Further if gypsum is a powdered source material, in a natural, pure or chemical form, it is preferably calcined since such material sets quickly and gives early mechanical strength.  A clinker of calcium sulphoaluminate may be produced for use as a powdered source material.

Abstract: ABSTRACT OF THE DISCLOSURE A process and device for the length trimming of cables from a cable supply for the processing of cable ends. The cable front end is inserted by a cable feed (20, 22) in a guide channel whose rear section is located in a swivel part (28).          As the cable front end impinges on a stop (102) on the swivel part (28), said swivel part swings beyond a dead center which is defined by a spring (40) which is attached eccentrically, whereafter the swivel part (8) is swung around by the spring (40) essentially 180° so that the cable front end bearing on the stop (102) points opposite to the feed direction.  The cable loop formed is then enlarged to the desired length by continued cable feeding, whereafter the cable rear end is severed by a knife (82).  By lowering the cable, the cable ends are transferred, accurately positioned, to holders (56) by means of which they can be transported to the processing stations.

Abstract: APPARATUS FOR SELECTING A REFERENCE LINE        FOR IMAGE DATA COMPRESSION                 ABSTRACT OF THE INVENTION         An apparatus for selecting a reference line for image data compression including a plurality of mutually connected reference selector chips for select-ing a reference scan line from vertical mode coding of image data.  The reference selector chips select a ref-erence scan line from a plurality of preceding scan lines in exclusive or combination of the image data of each candidate reference scan line with the image data from the input scan line.  The candidate reference scan line that has the lowest number of dissimilar bits is selected as the reference scan line.  Each candidate reference scan line has associated therewith a register having bit positions arranged from the highest order bit position to a lowest order bit position for storing a binary sum of the number of dissimilar bits.  When the sums are compared, the binary value and successive bit positions are compared from the highest order bit position to the lowest order bit position.  When the binary value for a compared bit position of a register is greater than the binary value in the corresponding bit position of another register, each reference selec-tor chip generates a losing signal for indicating that the register lost the arbitration   When the lowest order bit position of a register is not greater than the lowest order bit position of any other register and no losing signal was generated for that register, the associated chip generates a winning signal for indicat-ing which candidate reference scan line had the least number of bits dissimilar to the corresponding bits in the input scan line   Each chip further includes a cir-cuit for establishing a priority among the candidate reference scan lines so that two registers both having the smallest binary sum will not create a deadlock.
