Title: Frequency synthesizer with a phase-locked loop with multiple fractional division
Inventor: BRUNET ELIE
IPC: H03K23/68
Filed: 1991-08-19
Abstract: A frequency synthesizer e.g. for a frequency agile communications system comprises a single phase-locked loop controlled by a reference clock (5) and formed by a voltage-controlled oscillator (1), a programmable divider (2) with variable division rank M, a phase detector (3), and a loop filter (4). It also comprises a predetermined number n of fractional division structures (61, 6i, 6n), each implementing a frequency step P i  x F ref  lower than the reference frequency F ref . Each fractional structure (61, 6i, 6n) is coupled in parallel with the programmable divider (2) to add to said division rank M fractional increments P i  such that the ratio between the frequency F vco  provided by the oscillator (1) and the reference frequency be defined as a function of the increments P i  by the relationship: The increments P i  are derived from modulo-Q i  adders, programmed with values a; such that an incremating value +1 appears on the adder (6 i ) output for a; cycles out of Q; input pulses (at F ref ). By selecting the values Q i  to be relatively prime and inputting values a i  the frequency increments in output of VCO(1) are 1/(Q i xQ 2 ..xQ n ).

Abstract: A speed-reading training unit comprises a top cover 30 having a side card slot 301 for inserting training cards 31 thereinto, a top manual control slot 302, a digit window 303, and an exercise material window 304; an inner card (40 Figure 2) positioned below the top cover 30, having a push rod 401 extending upwards through the control slot 302, a flashing window (402) and a rectangular opening (403); and a speed-adjustment mechanism 404 provided below the top cover at one corner to be controlled by a knob 32 on the top cover 30. When a training card 31 is inserted into the card slot 301, the push rod 401 is depressed, and the push-button 50 is pressed, so that the inner card (40) may be shifted rapidly upwards and downwards. By focussing on words on the training card 31 flashing over the exercise material window 304, a user may enhance his/her speed-reading ability. Speed of movement of inner card (40) is determined by the tension in spring (42) which may be varied by rotation of pear-shaped member (41) attached to one end of the spring. Turning of knob 32 will cause simultaneous rotation of member (41). <IMAGE>

Title: Method and means for operating in a downhole wellbore tube
Inventor: PLEASANTS CHARLES W
IPC: E21B33/1295
Filed: 1993-12-30
Abstract: An expanding well tool and an actuating apparatus for expanding that tool are described. The tool comprises locking slips (68) for engagement with the tube to lock the tool in place. The slips are movable to their locking positions by the application of hydraulic pressure to the actuating apparatus to displace a drive sleeve (80) relative to a pull sleeve (82). The movement of the drive sleeve forces upper wedge members (44) against the locking slips to urge the slips into engagement with the tube well. Continuing hydraulic pressure displaces lower wedge members (50) upwards to engage the slips and lock them in their tube-engaging positions. <IMAGE>

Patent GB-2282415-A (GB)
Title: Rotary internal combustion engine
Inventor: RAVEN PETER JAMES
IPC: F02B53/00
Filed: 1994-09-29
Abstract: Annular rotors (R1 and R2) are positioned on each side of an annular stator (S) and are rotatable about an axis perpendicular to the planes of the rotors and stator and defined by shaft (SH). The rotors turn in opposite directions indicated by arrows (X and Y) and each rotor includes an even number of chambers (CH1 and CH2) with stepped transitions (TR) between adjacent chambers. The transitions (TR) are defined by transversely sliding sections (TF) which may move from a position level with chamber (CH1) to a position level with chamber (CH2) (an intermediate position is shown). The stator (S) has a housing surface (HS) which sealingly engages the chamber (CH1) but provides a free chamber space within the chamber (CH2). The stator includes sliding abutments (A8) which, during rotation, slide in contact with the surface of chamber (CH2) to travel on to the aligned surface of the transition (TF). The transition section (TF) then moves, by means not shown here, to be aligned with the surface of chamber (CH1) to allow the abutment (AB) to smoothly run on to the surface of this chamber. <IMAGE>
