Abstract: SCOTCH YOKE ENGINE WITH VARIABLE   STROKE AND COMPRESSION RATIO                          Abstract A yoke type engine wherein the orbital path of the slider is alterable to effect piston stroke and compression ratio changes.  A crank component has a crankpin which car-ries and positions the slider.  A boss of the crank component is carried by a control shaft in an offset manner.  Timing gears normally drive the control shaft in synchronization with the crankshaft to maintain a constant stroke and compression ratio.  Relocation of certain timing gears by an actuator causes the control shaft to rotationally advance or retard to reposition the crank component carried to thereby alter the orbital path of the coaxial crankpin and slider relative to a crankshaft axis.  High and low compression orbits for the slider may be selected to best suit engine loads.  A variable length throw couples the slider to the crankshaft.

Abstract: IMPROVED NOZZLE AND RETAINING ARRANGEMENT                ABSTRACT   A retention arrangement is provided for two members that are arranged to be assembled one within the other. The retention arrangement includes cooperating structure of the two members that is operative after the two membersare assembled to a predetermined point; for example, by the threading of one member within the other to a predetermined point of engagement. The cooperating structure includes the provision of an annular ridge formed on the inside of a first of the members, the first member being threadingly engaged or otherwise assembled into the second member, and the provision of an annular ridge on the outside of the second member. The two ridges move past each other after a first predetermined point of engagement between the two members. Further engagement of the two members causes the two ridges to cooperate so as to interfere with each other upon any tendency toward disassembly of the two members. In one specific embodiment, the first member is a tubular nozzle with external threads that is threaded into a second tubular, receiving member having mating internal threads. The annular ridge on the nozzle is provided on the portion of the nozzle that first enters the receiving member. The annular ridge on the receiving member is provided a predetermined distance within the receiving member to define a predetermined amount of engage-ment of the nozzle within the receiving member before the two ridges interact. Preferably, at least one ridge is provided with a tapered surface on the portion that leads the ridge in engagement. The annular ridge on the first member defines an increasing outer diameter along the direction of engagement and the second member defines a decreasing inner diameter along the direction of engagement.

Abstract: POSITIONING MISALIGNED DISK HEADS                     Abstract of the Disclosure Technique    for    dynamically    maintaining alignment of servo controls in a disk drive system which uses external indicia to position the head assembly between tracks containing embedded servo signals;   the   latter  used   to   control   track following.  Plural pairs of phase staggered track reference  signals  are  derived  from the  exterral indicia,  and  during  system  initialization  an optimal  pair  is  selected  for  controlling  head positioning.   The  system  is initialized both  at power  up  time  and  after  detection  of  certain errors.  The selection is made by using each pair separately to direct positioning of the head assembly over  a  predetermined  range  of  sampling positions  at  each  of  which  centering  offsets relative to the embedded servo signals are measured and  recorded  in  association  with  the  respective pair.  Based on an evaluation of these offsets, the system microprocessor  selects  a  reference  signal pair having the  least average offset  to control subsequent head positioning operations.  The system is then readied for "normal" read/write operation.

Abstract: ABSTRACT OF THE DISCLOSURE            "Method of Initially Establishing Burst Acquisition in TDMA Satellite Communications System and Arrangement therefor"         In order to initially establish burst acquisition in a TDMA satellite communications system, at least one of multiple earth stations (a first station) is controlled to instruct one of the other earth stations (a second station) to transmit an acquisition signal.  The acquisition signal is transmitted in a continuous manner and has lower power than normal or full power.  The first station receives the acquisition signal transmitted via a satellite transponder and detects a reference time point included in the received acquisition signal.  Thereafter, the first station obtains a time difference between the reference time point and a received reference burst time point.  The time difference intelligence is sent to the second station, which in turn transmits a burst at a time point determined by the transmitted time difference information.
