Abstract: In a sliding needle bar tufting machine in which displacement of a needle bar transversely of a tufted fabric undergoing manufacture to create a pattern in the fabric is effected by the action of rotary cam means on a needle bar carrier member, the invention provides single or single-acting cam follower means on the needle bar carrier member and a pair or appropriately spaced rotary cams of conjugate shape acting on said cam follower means. The use of two cams of conjugate shape makes it unnecessary for the individual cams to be symmetrical about their centers of rotation and thereby enables the production in the fabric of patterns which are asymmetrical in character.

Abstract: ABSTRACT OF THE DISCLOSURE      A multibeam antenna comprising Ne feed elements and emitting Nb beams each generated by a group of Nc elements has a feed device comprising a set of Nc power dividers.  These power dividers are unitary orthogonal distribution matrix power dividers of order P, where P is equal to the power of two equal to or immediately higher than the ratio Ne/Nc.  the outputs of the dividers are connected to the various elements in such a way that each element of one of the aforementioned groups contributing to a beam is connected to a different power divider and so that adjacent beams share feed elements.  A beam forming network has P x Nc outputs connected to amplifiers in turn connected to the inputs of the power dividers.  This network has Nb inputs.  The beam forming network is usually a low-level network.  The device finds a specific application in satellite communications.

Abstract: A novel keyboard is mounted in association with a circuit board with a light source which is mounted on the circuit board for emitting light. At least one depressible key is mounted for movement between a rest position and a depressed position, the depressible key having a body part which is formed of a light diffusing and transmitting material, the body part receiving light directly from the light source. A key cap is mounted on the body part, the body part moving concurrently with the key cap when the depressible key is depressed. A photoelectric member is mounted on the circuit board at a distance from the light source, the photoelectric member producing a change in electrical signal depending on the amount of light reaching the photoelectric member, at least a portion of the light reaching the photoelectric member being diffused through the body part when the depressible key is in the rest position. A light barrier is positioned between the light source and the photoelectric member when the depressible key is in the depressed position, the barrier shielding the photoelectric member from the light which is directly emitted from the light source and from the light which is diffused through the body part when the depressible key is in the depressed position.

Abstract: For supporting of formwork in constructing buildings, use is made of steel post shores (props) having a pin with recessed areas thereon. When the prop has to be brought from the loaded to the unloaded position, such pin is changed of position in the prop so as to allow the inner tube to be lowered within the outer tube of the prop. The invention provides a new pin-design such that after assembling the prop it can be clearly seen wether the pin finds itself in the correct position or not. For that purpose, use is made of a pin having a recess and a flattened portion; by axial displacement of ache pin this portion rests on a ring or on an inner tube under changing its angular position, which is well visible for the user.      Alternativily a cylindrical pin may have two cams resting on a ring; by axially displacing this pin it will rotate over 90° and the inner tube will be lowered in the outer tube, which position is clearly visible for the user.

Title: Combined range laser scanner
Inventor: SALATTO PATRICK JR
IPC: G02B26/10
Filed: 1991-11-27
Granted: 2001-10-16
Abstract: A combined range laser scanner and method for electro-optically reading indicia such as bar codes having parts of different light reflectivity which utilizes two laser diode optical illumination systems optimally focused for different working ranges. A first laser illumination system is optimized for contact operation and has a range extending to approximately two feet. The second laser illumination system is optimized for longer range scanning from approximately two to seventeen feet, and the two laser scanning systems are integrated into one combined range laser scanner. The combined range laser scanner incorporates therein logic circuitry which enables either laser illumination system as required fro the particular scanning application. Depending upon which laser illumination system is selected, the laser spot speed (e. g. amplitude of the drive signal for the scanning motor) is controlled to limit the frequency of received light signals to that of standard signal processing and decoding circuits. scanning is achieved with a common oscillating mirror element driven by a scanning motor, and the amplitude of the applied scanning motor driving signal is greater for the first laser illumination system optimized for contact or short range operation and less for the second laser illumination system for longer range scanning.

Abstract: A self-tightening clamp formed from spring steel band material which exert clamping forces by the inherent springiness of the band material.  To  minimize outwardly projecting parts with their injury danger and to obtain an inner clamping surface substantially devoid of any gaps or steps, the end of the outer band end portion is provided with an elongated slot adapted to receive the tongue-like overlapped inner band end portion.          Temporary locking of the clamp is realized by a detent member in the tongue-like inner band end portion adapted to be lockingly engaged by a locking surface in the outer band portion.  The elongated slot is thereby of such width as to accommodate the tongue-like inner band portion whereby the detent member is located in the elongated slot when the clamp is in its clamping position.

Abstract: In a process for fabricating a multilayer printed circuit board with permanent innerlayers of photoresist, the photo-imageable composition used to form the hard permanent layer comprises a polymerizable acrylate monomer; an oligomer formed by the reaction of an epoxy resin and an acrylic or methacrylic acid; a photosensitive, free radical generating initiator for polymerization of the acrylic monomer and oligomer; a curable epoxy resin; a curing agent for the epoxy resin; and, optionally, a crosslinking agent reactive with hydroxyl groups. After exposure and development of a layer of the photoimageable composition and etching of the underlying metal layer on a board, the resultant photoresist is left on the circuitry traces.  The innerlayers of photoresist are stacked in a press where it initially conforms under heat and pressure to fill voids between the innerlayers and then cures to permanence.
