Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a novel loading and unloading apparatus for use by wheelchair confined and other disabled passengers.  One embodiment of the invention makes provision for loading and unloading such passengers at en-trances to existing passenger carrying vehicles.  A horizon-tal loading platform is pivotally connected to a pair of spaced apart and opposed linkage means positioned on either side thereof and which are in turn pivotally connected to the passenger vehicle.  Each linkage means comprises five linkage sections which are so arranged as to define two co-operating parallelograms having one common side which is parallel to the loading platform.  An offset arm forms part of each inboard linkage connected to the vehicle and to each said arm a thrust link is pivotally connected and is further extended to a point of pivotal connection with its complimen-tary outboard linkage from which the loading platform is suspended.  The length of the offset arms and of the thrust links as well as the location of the pivotal connection of the thrust links to said outboard linkages control the path of movement of the loading platform.  Electrically, pneumat-ically or hydraulically powered motive means is utilized in raising and lowering the loading platform along said con-trolled path between vehicle floor elevation inboard template line of vehicle and ground elevation outboard template line of vehicle.

Abstract: 43-47/R2.19 IMPROVED BLOWOUT PREVENTER ABSTRACT OF THE DISCLOSURE       A  oil  well  blowout  preventer  includes  a  radially compressible annular packing having radially-sectored end portions in a housing having axially aligned upper and lower bores communicating with the inner bore of the packing and with the  sectored  ends,  and  also  includes  hydraulic  means  for radially constricting the packing,  thereby causing it to axially  expand.    A  plurality  of  circumferentially-arranged rigid wedge members carried by the sectored endportions are individually movable radially into the bores to control  the axial expansion whereby radial sectors of the packing may move sequentially inward to effect  a  seal  between  the  upper  and lower bores in response to progressive axial expansion of the packing as the packing undergoes nonuniform sector-wise radial compression.   The inward radial movement of the rigid members are limited by stops to a common radial position independent of the uniformity of the radial compression. The blowout preventer effects a seal between the inner bore and the upper and lower bores regardless of the presence of an oil well tool therein.

Abstract: ABSTRACT OF THE DISCLOSURE           A d.c. generator is connected in series opposed to the polarity of a d.c. power source supplying a d.c. drive motor.  The generator is part of a motor-generator set, the motor of which is supplied from the power source connected to the motor.  A generator field control means varies the field produced by at least one of the generator windings in order to change the effective voltage output.          When the generator voltage is exactly equal to the d.c. voltage supply, no voltage is applied across the drive motor.  As the field of the generator is reduced, the drive motor is supplied greater voltage until the full voltage of the d.c. power source is supplied when the generator has zero field applied.  Additional voltage may be applied across the drive motor by reversing and increasing the reversed field on the generator.  The drive motor may be reversed in direction from standstill by increasing the generator field so that a reverse voltage is applied across the d.c. motor.

Abstract: ABSTRACT OF THE DISCLOSURE     An integrated continuous low energy rendering process for preparing stabilized fat, protein meal material and gelatin or glue stock material from raw organic material containing fat, water, and proteinaceous material, such as a mixture of raw bone and raw meat tissue.  The raw organic material is fed continuously without heating or finely grind-ing into a press, preferably a screw-type press mounted within a cage, from which a large portion of the fat and soft low density proteinaceous material, such as meat tissue, are extruded separately from the high density proteinaceous material, such as bone and sinew.  The extruded soft low density proteinaceous material and fat in the form of an aqueous fatty slurry are subjected to moderate heating to melt the fat therein followed by centrifuging to separate from the slurry most of the fat in the form of crude fat material.  The crude fat material separated from the slurry is subjected to centrifuging or evaporation and filtering or settling to remove water and suspended solids to provide a clear high quality stabilized fat product.  The low density proteinaceous material from the centrifuge is mixed with the high density proteinaceous material from the press, and the mixture is heated to effect crisping and drying to a low moisture content, such as 10 wt.%, and preferably sized within a selected particle size range to provide a low-fat protein meal material.  Where the raw organic material contains a large amount of bone, the dried mixture is subjec-ted to a dry gravity separation treatment to recover a select particle size range of low-fat high density proteinaceous material suitable for making high quality gelatin.

Abstract: Abstract of the Invention Apparatus for interpolating data along radial lines so that it can be displayed at display points arranged in orthogonal rows and columns by recursively adding stored values to derive signals indicative of the radial position of each display point along the radial data lines and its angular position between the radial data lines.  Interpolation is done along each radial line to derive first and second intermediate interpolated values, and these values are inter-polated so as to derive the final data value for the display point at its angular position.   Alternatively, the intermediate interpolated values can be attained by angular interpolation and the final data value by radial interpolation.

Abstract: ABSTRACT      The present invention relates to the replacement of an existing main, particularly an existing cast iron gas main, with a new main utilising a device in the form of a mole.          The mole 1, which is of steel, is adapted to be inserted into and moved along the existing main 8.  The mole 1 has a front portion comprising a head 2 and a cylindrical body portion 3 and a rear portion having clamping means 4 for clamping a new main 13.  The head 2 has a cutting face 5 for engaging the internal wall of the existing main 8 so as to cause the wall to fracture as the mole 1 moves therealong.  Th new main 13 which in use is clamped to the mole 1 is towed along behind the mole 1 to replace the fractured old main 8.  In one embodiment of the invention (Figure 1) the cutting face 5 comprises three or more cutting edges 6 formed by grinding on high tensile steel cutters 7 which are located in keyways in the head 2.  In another embodiment of the invention (Figure 4) the cutting face 25 may comprise three or more pivotally mounted cutting blades 26 which are pivotally mounted at their forward ends 27 to the wall of the head 23.  The blades 26 are caused to pivot radially outwardly from their closed position to engage the pipe wall 45 and fracture it as the mole moves along the pipe towing the new main 43 therewith.     In still another embodiment of the invention, (Figure 10) only one 58 of the blades is pivotally mounted at its forward end 59 to the mole 51, the other blades 56, 57 being fixed.  In this embodiment, the mole 51 is driven through the existing main 94 by means of a pneumatically actuated hammer 80 (Figure 8) engaging percussively with an internal wall of the mole formed by an internal bore 82.          The pivotal blade 58 pivots under the action of an associated piston 64 which is hydraulically actuated by fluid supplied from a hose 103 by way of a channel 70.  The blade 58 is normally closed but is pivotted to fracture any circumferential located obstruction located in the main 94 and serving to inhibit the movement of the mole 51 therethrough.
