Title: Separating the strands of a yarn
Inventor: HANNAH JAMES RAYMOND
IPC: B65H63/06
Filed: 1991-01-26
Abstract: To separate and recover the component strands of stranded yarn, yarn (8) from a package of two-ply yarn is supplied to a tensioning means (10), is divided by a divider finger (30) into its two strands and the latter are wound onto respective rotary skein-forming wheels or swifts (18). The finger (30) is pivotally mounted so as to move in response to the passage of the yarn. The swifts (18) are turned by a motor (M2) to draw off the yarn from the yarn package which is rotated in the direction opposite to the twist by a motor (M1). The yarn strands are evenly distributed on the swifts by a guide device (14) driven by a third motor. When the yarn breaks or is absent, the finger (30) operates a switch to stop the motor (M1). If the yarn is tangled, the finger (30) moves in the opposite direction to operate a switch to stop motor (M2) and the third motor. <IMAGE>

Title: A gap seal having both contractible and expandable portions
Inventor: KEYS JAMES FREDERICK
IPC: B60J10/00
Filed: 1991-05-13
Abstract: An article for sealing a gap between a first surface and a second surface which are spaced from one another includes an elongated body 12 with a first sealing surface for sealing against the first surface and a second sealing surface for sealing against the second surface. The body portion includes a resilient contractible portion 14, 118 and an expandable portion 16, 120. The contractible portion may be contracted by evacuation and the expandable portion expanded by fluid (which may be settable) and retained in the expanded position thereby bridging a gap between the first surface and the second surface.

Title: Camming differential mechanism has frictional engagement between cam output member and input
Inventor: YOUNG ALASTAIR JOHN
IPC: F16H48/12
Filed: 1992-04-15
Abstract: A differential mechanism (10) comprising two output cam members (16, 17), each having a single annular cam surface (22, 23) thereon, comprising pairs of inclined surfaces. Relative contra rotation of said output cam members (16, 17) causes cam followers (28) to slide axially, and housing (11) engages the followers (28) which are slideably supported by the housing (11) moving the followers circumferentially relative to the output cam members. The two cam output members (16, 17) are thrust axial against the housing (11) during drive of the cam output members (16, 17) through the followers (28) and at least one cam output member (17) acts against the housing (11) through a friction thrust washer (51). This allows control of the torque ratio between inside and outside output shafts in a corner.

Title: Can body with flexible panels
Inventor: CHRISTOPHER PAUL RAMSAY
IPC: B65D8/12
Filed: 1992-04-25
Abstract: A sheet metal can body 1 comprises an end wall 2 and a tubular side wall 3 which includes a plurality of flexible panels 4 recessed within the cylindrical envelope of the side wall and extending between plain cylindrical end portions 5 of the side wall. Each panel 4 is formed of a plurality of elongate concave flutes 6, each flute being defined laterally on each side by a convex rib 7. The panels may be separated circumferentially from adjacent panels (Figures 1-5) or contiguous, in which case the outer rib of each panel is arranged to lie on the cylindrical envelope of the side wall such that the perimeter and envelope of the side is substantially constant along the entire length of the side wall. Preferably, at least in the longitudinal middle region of the panels, the ribs of the flutes lie on a chord of the cylindrical envelope of the side wall (11, Figure 5). Each panel may have 2 to 8 flutes. The panels flex when the can body is subject to internal pressure increase or reduction, eg during or after processing of the food or fruit juice in the can. <IMAGE>
Patent GB-2263986-A (GB)
Title: Rotators in instruction length calculation.
Inventor: GROCHOWSKI EDWARD T
IPC: G06F9/32
Filed: 1993-01-14
Abstract: A circuit for determining the length of an instruction includes apparatus for providing a sequence of instruction bytes greater than a single instruction length and rotator apparatus for selecting a sequential number of instruction bytes for decoding commencing at a byte which begins a first instruction. Apparatus responsive to a decoded length value derived from the first instruction causes the rotator to rotate to the beginning of a next instruction. Using a rotator instead of conventional carry propagate adders to indicate the beginning of the next instruction allows a second pipeline (eg. in super scaler processors) to begin decoding the next instruction sooner. Consequently the speed with which instructions may be decoded and executed is increased in both pipelines. <IMAGE>

Patent GB-2272543-A (GB)
Title: Synchronous digital detection of position error signal
Inventor: WILSON ROSSER S
IPC: G11B5/596
Filed: 1993-08-11
Abstract: This invention relates to the detection in digital form of position error signals (PES) by employing a digital integrator (36) which comprises a register (48) and adder (46). A composite servo data is amplified by variable gain amplifier (22) and then undergoes low pass filtering (26) before being digitized by an analog to digital converter (ADC) (34). The digital integration is performed by accumulating a constant number of ADC samples in the register (48). Before being accumulated in the register (48), the sampled servo data is alternately multiplied by plus one or minus one for synchronous rectification, using an exclusive-OR gate (44) cascade interposed between the ADC output and adder input. Upon completion of accumulation of a prescribed number of ADC samples, the contents of the register (48) are transferred to a temporary buffer (30) pending interrogation by a servo controlled digital signal processor (DSP). <IMAGE>
