Abstract: Long utility holes, for gas lines, electrical conduit, communications conduit and the like, may be bored or pierced horizontally through the earth, particularly under obstacles, such as buildings, streets, highways, rivers, lakes, etc. Such holes may be bored by an underground drilling mole (17) (underground percussion drill) supported on a hollow drill rod (15) and supplied with compressed air through the rod to operate an air hammer which strikes an anvil having an external boring face, prefer­ably constructed to apply an asymmetric boring force. The drill rod is operated by a drill rig on the surface or recessed in special pit for horizontal drilling and provides for addition of sections of pipe or hollow rod as the boring progresses. The asymmetric boring force causes the boring path to curve and, when straight line drilling is needed, the drill rod is rotated to counteract the asymmetric boring force. An alternative bor­ing tool utilizes an expander supported on a solid or hollow drill rod and having a base end supported on and larger in dia­meter than the rod and tapering longitudinally forward there­from. It may have a uniform extension protruding a short dis­tance forward. The tool penetrates the earth upon longitudinal movement of the drill rod.

Abstract: In a receiver comprising a filter section for filtering a transmitted digital signal into a filtered digital signal and an equalizer section for equalizing the filtered digital signal into an equalized digital signal as a reproduced digital signal in response to controllable tap gains supplied from a control arrangement, the equalizer section comprises a first arrangement for filtering the filtered digital signal in response to predetermined ones of the controllable tap gains to produce an intermediate digital signal and a second arrangement for equalizing the intermediate digital signal into the equalized digital signal in response to remaining ones of the controllable tap gains except for the predetermined controllable tap gains to produce the reproduced digital signal. The control arrangement controls the predetermined tap gains so as to minimize noise power of a noise signal accompanying the filtered digital signal and the remaining contollable tap gains and to equalize the intermediate digital signal into the equalized digital signal.

Abstract: A plate member (12) has a wire engaging edge (14) and a corresponding number of open-ended wire guide channels (16), each extending inwardly from the edge (14) to a closed end (20) spaced apart by a center­line spacing (Y) different from the centerline spacing X of the the open ends (18) in said edge (14). The plate (12) is reciprocably moveable between a first position wherein the open ends (18) are in surrounding engagement with the wires (22) (see Fig. 1) adjacent the edge (14) and a second wire-receiving position wherein said wires (22) are disposed at the closed ends (20) (see Fig. 2). In use of the guides actuation means, e.g. machine table (138) (see Fig. 6) moves the plate member (12) between said first and second positions. Actuation of the guide causes movement of the wires (22) within their respective channels (16) to alter the centerline spacing thereof. The guide is useful for making smooth continuous transitions between production runs of different pitch wire harnesses. It is also useful for making pitch transition wire harnesses (92) (as shown in Fig. 5) wherein a common group of wires (22) are terminated to at least two connectors (94, 100), each one containing terminals (102, 116) spaced apart at different centerline spacings.

Abstract: There is disclosed a speech recognition system and technique which is of the acoustic/phonetic type. It is made speaker-independent and capable of continuous speech recognition during fluent discourse by a combination of techniques which include, inter alia, using a so-called continuously-variable-duration hidden Markov model in identifying word segments and making all steps of the technique responsive to the durational information, and using a separate step for aligning the members of the candidate word arrays with the acoustic feature signals representative of the corresponding portion of the utterance, including using pairs of candidate phonetic segments in the alignment technique. Any residual word selection ambiguities are then more readily resolved than in the prior art, regardless of the ultimate sentence selection technique employed.

Abstract: A method and apparatus for locating a sleeve within a surrounding tube and pressure-tightly sealing the sleeve within the tube to repair leaks in the tube. The sealing method utilizes dual elongated pressurizable tools. The first tool device includes a housing having a reduced-diameter forward extension portion attached to a front cylinder, and containing a rear piston. The front cylinder, is attached to a collet having multiple radially expandable fingers and contains a front piston attached to a tapered mandrel which is axially movable within the fingers, and has a forward tapered nose portion to facilitate inserting the tool into a tube. The rear piston is attached to the front piston by an elongated rod. By pressurizing the tool front piston by a hydraulic fluid pressurizing unit, the mandrel is forced forward through the collet fingers to expand the fingers against the sleeve and thereby expand the sleeve tightly into the tube to form the seal joint. After withdrawing the tool from the tube, the tool rear piston is similarly pressurized to retract the front piston and attached mandrel back through the collet expandable fingers to reset the tool prior to its further use. The second tool includes a housing containing an axially movable piston and a forward reduced diameter portion and having an elastic expander unit for inserting into the sleeve and tube in a tubesheet. The expander unit consists of at least two elastic rings composed of an elastomer material and each having a chamfer provided at the outer edge of the unit forward and rear faces. By pressurizing a port at the housing front end, the piston is moved rearwardly to axially compress and expand the expander rings radially outwardly sufficiently to expand the sleeve firmly into the tube and provide a pressure-tight seal therebetween. Following such expansion of the sleeve, the piston is pressurized and moved forward to release the compression on the expander unit rings, so that the tool can be easily withdrawn from the expanded sleeve and tube and inserted into another sleeve and tube for repeated usage.

The lock of the lid of the tape cassette is released when the tape cassette is lowered to the loading position and the lid is opened by engagement with a lid opening mechanism.

Abstract: The web (W) is reeled by supporting the roll (30) from its outer circumference by means of at least two supporting units (10,20), of which the first one, in the direction of arrival of the web (W), is a carrier roll (10) provided with a mechanical rotating drive (10a), over which the web (W) is passed to reeling. The carrier roll (10) forms a reeling nip (10/30) supporting the roll (30) from below. Above the roll (30), a press roll (21) is used, by means of which the roll (30) is kept stably in its reeling position. The roll (30) is grown around a core (31) under a nip support between the carrier roll (30), a belt roll (12) and the upper press roll (21). When the roll (30) grows and becomes larger, the reeling goes on further under the nip support between the carrier roll (10) and the upper press member (21) and, in addition to this supporting, on a belt supporting zone placed as a direct extension of the nip support zone of the belt roll (12). The final stages of the reeling are carried out up to full roll (30) by extending the belt support zone and, at the same time, by adjusting the tensioning (T) of the support belt or belts (15) so that the linear loads in the various supporting nips of the roll (30) remain within suitable limit values in view of the progress of reeling and of quality of roll (30).
