Abstract: A method of forming end stops to a continuous slide fastener chain including element-free space portions at long-itudinally spaced intervals, wherein as the chain is fed in the backward direction, a pair of rows of interengaged coupling elements extending on the downstream side of an element-free space portion is spread open by a chain splitting apparatus for subsequent molding of a separable end stop whereas a pair of rows of coupling elements on the upstream side of the ele-ment-free space portion is kept in engaged condition.  After the separable end stop is molded, the chain is fed in the for-ward direction during which time a sprue portion and gate portions formed integrally with the separable end stop are caught by a chain splitting member of the chain splitting apparatus.  The chain splitting member is then lowered to automatically remove the sprue portion and gate portions from the separable end stop.

Abstract: A circuit, for monitor-ing and controlling parame-ters of an electrosugical unit (10), ESU, relative to load and the RF energy, has a load re-sponsive output sensing cir-cuit (11) that measures the ESU load. A signal modifier (12) attached to tbe sensing circuit (11) enhances the sig-nals measured and transmits them to a buffer (13). An ana-log to digital converter (18), A/D, digitizes the signals and samples wave pulse train at about eight million samples per second. A data memory (21) stores the digitizod sig-nals. An RF drive clock (27) connects to the ESU output; a sample clock (19) uses phase shifting to interrogate the in-put signals to a processor (20), DSP, at a greater sampling rate of frequency than without. The DSP receives the stored signals from the data memory (21) and processes them while monitor-ing and calculating ESU parameters measured, i.e. voltage, current, power, load impedance, leakage current, peak to peak voltage, peak to pealc current, spectial content and/or crest factor of the RF wave pulse train energy to use as controlling feedback to eitber a high voltage power supply in tbe ESU, regulating tbe RF drive pulses or both. A method monitors and controls the ESU relative to load and has the steps of collecting parameters with the ESU output sensing circuit (11) responsive to loads; enhancing signals with the signal modifier (12); transmitting signals to the buffer (13); converting signals with the A/D converter (18); storing signals in the data memory (21); receiving signals in the DSP, and processing, monitoring and controlling signals by repeatedly measuring ESU output parameters.

Abstract: A method and apparatus for directing electromagnetic energy may be used as a di-rected energy weapon, illuminator for an active sensor and/or guidance system, counter-measure, or to ignite a fusion weapon; as a beam expander; for power transmission by a beam; propulsion by a beam or inertial fusion; power generation from inertial fusion; telecommunication; or computer hardware. The method and apparatus direct electromag-netic energy from a source made up of an area or volume as opposed to a point. Electro-magnetic energy of at least one wavelength is emitted first towards a defined surface and thence to a defining surface. Each surface is either everywhere reflective or refractive, and each point on the defined surface lies at a point of intersection of a pair of defining rays radiating from different points on or within the source. Each defining ray is of a defining wavelength. Each defining ray is reflected or refracted by the defined surface and is then incident to the same side of the defining surface at a respective further point where it is reflected or refracted through a respective predetermined directed angle. The directed angle of a half-tangent to the defining surface which is co-planar with the two defining rays and lies at any intermediate point on the defining surface between the two respective further points is intermediate between the directed angles of two similarly orientated half-tangents which are co-planar with the two defining rays and lie at the respective further points. A further ray from said source and of said defining wavelength passing through said point of intersection and also any one of such intermediate points is reflected or refracted by the defining surface through a directed angle intermediate between the two respective predetermined directed angles or approximately equal to one of them. The accuracy with which the electromagnetic energy is directed is improved by the provision of a plurality of stages wherein each stage includes a defining surface together with a defined surface and the electromagnetic energy output from a stage forms the input to a further stage.

Title: Mattress cover handle
Inventor: KORB LOTHAR
IPC: A47C31/08
Filed: 1996-07-10
Granted: 2001-01-09
Abstract: A handle for a mattress border is anchored with spaced grommets in the border against which anchors on the handle ends may bear.  The anchors are designed to allow a leading end of the handle to be drawn through a grommet opening.  A back strap between the grommet openings is shaped to allow clamping to move the grommet openings to aligned position.  To allow the drawing of the anchors through the grommet openings, at least one of the anchors is provided with first coupling means.  A puller rod is designed to be inserted through at least one of the grommet openings.  The puller rod is provided with second coupling means, designed to cooperate with the first coupling means to achieve the pulling function.  In one variant the clamping means may be used to bend the back bar and border into a 'U' shape, with the inside of the border on the convex side of the U, so that a straight puller rod may pull the leading anchor through the aligned grommet openings in the sequence inside to outside to inside relative to the border material.  In a second variant the clamping means act so that the 'U' shape becomes more like a 'V' so that the grommet axes may be considered to be on a common arc.  A curved puller rod, with a second coupling means on its free end is moved to pass through both grommets in an anti-pulling direction to couple the first (handle) coupling means to pull its leading end through the two grommets.  In a third variant using two puller rods the handle is first shaped in a downward arc over a flattened border with the back strap at the bottom.  The free end of a puller rod projects through each grommet opening.  The border and back strap are then bent into a V the rods travelling to maintain their position relative to the grommet opening.  This achieves coupling of each pair of first and second coupling means.  The puller rods may then be retracted to pull the handle ends through the grommets.

Title: Process for transmitting a sequence of information bits with selective protection against transmission errors, coding and correction processes which can be implemented in such a transmission process
Inventor: LASNE XAVIER
IPC: H03M7/32
Filed: 1996-11-06
Granted: 2006-02-14
Abstract: Based on the sequence of the information bits to be transmitted, the coder forms a second sequence of bits c n, which includes a redundant subset. A differential coding of the form d n=c n~d f(n) with f(n)<n produces a third sequence of bits d n. The signal sent represents the bits of the third sequence in a specified order. Having obtained likelihood data r n associated with the bits d n, the receiver calculates estimates of the bits c n of the redundant subset as a function of the sign of r n . r f(n). By exploiting the redundancy, the receiver can detect the bits c n of the subset having erroneous estimates, and rectify the sign of the less reliable of the two associated likelihood data items r n and r f(n). The other bits c n' of the second sequence then benefit from additional protection if there is at least one bit c n of the redundant subset such that n' =f(n) or f(n')=n or f(n).
