Abstract: ABSTRACT OF THE DISCLOSURE     A time division digital switching network in which first-order digital data channels transmit words including a given bit number, have first rates different from, but multiple of, one another, and are time-multiplexed into second-order channels having a second predetermined rate and each comprising a com-bination of first-order channels at different rates ri.  In each combination, xi words are at the rate xi and the quantity .SIGMA. rixi defines a multiframe.  The second-order channels are time-multiplexed into a third-order channel having a third predetermined rate.  In the digital switching unit of the net-work, the first-order channel words multiplexed into the third-order channel are grouped at an address whose first part de-pends upon the second-order channel they occupy in the third-order channel and whose second part is derived from the word number in the multiframe corresponding to a given first-order channel according to the multiplexing schemes.  The bits of a given rank of the second-order channel words form a pseudorandom sequence and, therefore, the bits of a give rank of the third-order channel words form interleaved sequences.  The switching unit includes means for separating these interleaved sequences and for deducing from the bits composing them the second address part of the words and from the latter the addresses of the first-order channels.

Abstract: ABSTRACT THE DISCLOSURE An apparatus for detecting relative movement between two objects which is illustrated in the preferred enbodiment as a vehicle road speed signal source including a reed switch oscillator for generating an output signal having a frequency and a magnitude proportional to the road speed of an associated vehicle. Current flows through a biasing coil proximate the reed switch to generate a magnetic field which is slightly less than the field required to close the switch contacts. A permanent magnet means attached to the drive shaft of the vehicle generates a magnetic field which aids the biasing coil magnetic field to close the reed switch contacts. A transistor responds to the closing of the reed switch contacts to turn off the current to the biasing coil which allows the reed switch contacts to open. The transistor responds to turn on the biasing coil current and the cycle is repeated to generate a pulsed signal as long as the magnetic field from the permanent magnet means is present once each revolution of the drive shaft. The oscillator pulsed output signal is shaped into a triangular output signal having one peak for each revolution of the drive shaft.

Abstract: ABSTRACT OF THE DISCLOSURE A coupler assembly for a portable washing machine which includes an improved method of assembling and retaining the faucet locking means between the coupler body and the re-taining ring. The coupler body supports locking means in pockets between the retaining ring and the body.  The retaining ring includes a plurality of inwardly extending segmental shoulders which define recesses therebetween.  The retaining ring is assembled onto the coupler body by aligning the recesses with the locking means and sliding the ring onto the body.  The re-taining ring is then locked by rotating the ring to snap a leg portion into a detent slot in the body.  The locking rotation moves the segmental shoulders into alignment with the locking means to prevent movement of the ring from the coupler body.

Abstract: ABSTRACT OF THE INVENTION       In a self-transportable aerial platform, an operator employs a handle for controlling the verticl, horizontal and lateral movements of the platform in order to place the basket or platform at a preferred location.  The operator controlled handle operates a linkage which actuates one valve of a control to produce a first mode of platform movement; the handle is movable in a second direction to displace separately and dis-tinctly a second valve for a further mode of operation; and the handle can further be twisted or turned to effect a separate and distinct movement of a third valve for the final mode of plat-form movement.  The linkage consists of parallelogram linkage having the capability that one of said links can serve as pivot for the other link, both of said links can be pivoted in unisom as part of a parallelogram linkage, and both links of the parallelogram linkage can serve as journals for twisting movement of the handle which effects the additional mode for platform movement.           Each of the described handle movements separately, independently and distinctly operate an associated valve so that movement of the platform can be isolated to vertical, horizontal, or lateral movements or a combination of handle movements will effect concurrent and composite movements of the platform in the direction determined by the handle operation.

Abstract: ABSTRACT OF THE DISCLOSURE        Polytetrafluoroethylene resin tubes having small pore size and a thickness to inside diameter ratio of 0.07 or less, and yet at the same time, having a high porosity, are produced by a process which includes stretching the tubes by drawing using a metal die and a metal plug.  By using the die and plug, the stress necessary for stretching is converted to a compressive force in the thickness direction of the tube.  This compressive force is an essential factor in producing the microporous structure of the tubes.  The tubes provide meaningful materials for artificial tubular internal organs or industrial filtration.
