Abstract: ABSTRACT   A prosthetic cement spacer for controlling the thickness of cement applied between a prosthetic insert and a support member, such as an acetabulum, includes a generally cylindrical standoff body portion fabricated from acrylic bone cement and a pointed wire concentric with said standoff body and outwardly extending from one end a sufficient length to anchor into the acetabulum bone surface.          The method of use of these prosthetic cement spacers involves preparation of the acetabulum so that there is sufficient clearance space for the prosthetic cement spacers and then to insert the pointed wires into the acetabulum bone surface in an equilateral triangular arrangement thereby providing three points of contact for the prosthetic insert, such as an acetabular cup.  By selecting three prosthetic cement spacers all having substantially the same standoff body height, the clearance region between the acetabulum bone surface and the acetabular cup is controlled and provides a uniform cement thickness throughout thereby providing an improved bonding arrangement.

Abstract: Abstract A high speed analog-to-digital conversion method and  apparatus  including  a  plurality  of  parallel analog-to-digital converters is disclosed. A clock sig-nal is applied to each of the analog-to-digital conver-ters at different phase relation to increase the equiv-alent sampling frequency by multiplexing the outputs into  a  serial  form.  A  reference  signal  such as  a linear ramp or sawtooth signal is used to maintain the correct phase relation, thereby eliminating any errors due to differences in electrical characteristics among the analog-to-digital converters. Such correction may be performed automatically by using a CPU before digi-tizing an analog input signal or at any desired time.

Abstract: Basic frame for an adjustable damper-actuated chair ABSTRACT   The invention provides a generally usable, extremely simplified ba-sic framework for a chair such as an easy chair with an adjustable back support, which can be locked in different positions, the basic framework including the necessary mechanism for adjusting the back and locking it in a desired position. Said framework comprises two simple frames or panels, forming a seat part and a more elongate  back support part, and a frame holder united to the seat part for carrying the framework. Both parts are joined to each other by means of a transverse hinge in such a way that a lever of a given length is formed between the hinge and the adjacent short side of the back support part. A gas damper is articulately coupled between the said short side of the back part and the holder joined to the seat part. The back support part is caused to swing by the stroking movement of the gas damper and, by closing off the gas transfer duct in the damper by means of an ope-rating lever, the framework  can be locked with the back portion assuming the desired sloping attitude.

The hydrocarbon solvent is then separated from the resultant solution and a composition comprising nigh molecular weight polymer is recovered.  Any catalyst residues remain with the polymer.  In a preferred embodiment the catalyst contains vanadium.  A particular salt is the salt of a C8 aliphatic acid, especially calcium 2-ethyl hexanoate.

Abstract: Abstract Apparatus for converting successive groups of neighboring stacks of paper sheets into a row of spaced-apart equidistant stacks has a first transporting unit which receives at intervals groups of stacks from a maker and advances successive groups at intervals lengthwise so that the neighboring groups are separated by gaps.  The first transporting unit is followed by a second transporting unit having a series of gathering conveyors which are driven at a relatively low constant speed and some of which can be driven at intervals at a higher second speed to thus cooperate with the first transporting unit, whose speed can be varied between zero speed and the second speed, in order to eliminate gaps between successive groups and to form a composite group of immediately adjacent stacks.  Such composite group is broken down into a row of spaced-apart equidistant stacks by several singularizing conveyors of a third transporting unit which receives successive stacks from the foremost gathering conveyor of the second unit and successive conveyors of which are driven at higher speeds to increase the clearances between successive stacks of the row to a desired value in stepwise fashion.
