Inventor: LOUGHLIN B D
IPC: H04H1/00
Filed: 1979-06-01
Abstract: An improved transmitter for a compatible independent sideband (ISB) AM stereo system develops a phase modulated carrier where the modulation represents the stereo difference signal inverse modulated by the stereo sum signal in accordance with a selected modulation function. The phase modulated carrier then is amplitude modulated by the stereo sum signal. This simplified modulation scheme provides the second-harmonic sideband correction required to develop a true single sideband type signal wherein left and right stereo information are transmitted in separate lower and upper sidebands, which can be demodulated without distortion in ISB AM stereo receivers. Simplified receivers which use inverse modulation are also disclosed.

Abstract: For the purpose of making a joint socket comprising at least two portions, namely a portion for receiving a plastic pipe end and another portion into which a rubber ring is fitted, a method of heating and softening a plastic pipe end and enlarging the radius of the softened pipe end to twice its size which includes, an inwardly slanted portion between a first outwardly slanted portion and a second outwardly slanted portion whose radius becomes smaller as it comes nearer to the front end thereof. As the result, the frictional resistance between an improved core and the radius enlarged softened pipe is reduced to a value which enables the method to be carried out such that wall-thickened sockets can be made without loss of wall thickness subsequent to the radius enlarging process. The core for forming a molding space includes the first outwardly slanted portion, the inwardly slanted portion and the second outwardly slanted portion and which are necessary to perform the method can be expanded and shrunk so as to pass through the small and large radius portions of the molded socket and has a self-locking mechanism capable of resisting the resistance caused between the forcedly fed pipe and the core.

Abstract: A bar code printer is disclosed which may be used as a standard desk type bar code printer, a weighing bar code printer, etc. by connecting outer peripheral equipment, such as weighing instruments or price indicating balances, to the bar code printer. A change-over circuit can select an input signal from either the input unit of the bar code printer or from the outer peripheral equipment, the input signal energizing a control circuit which develops control signals to drive a bar code printing system and an indicating system. The printer has differing types of bar code systems stored therein and by entering a flag code, a specific bar code system may be selected. Also, the differing types of bar code systems may be accomodated since the bar code is divided into a fixed part (for common use in all systems) and a variable part (differing numerals between bar code systems). The column numbers of the variable part of the bar code may be identified prior to introducing print data via the input unit and the numerals from the input for the variable part may be input thereinto. The printing system includes a plurality of heating elements which contact a heat sensitive surface of the labels. This causes the printing of the bars on the bar code label. The control circuit may include means for maintaining a constant, uniform width of the bars on the bar code label.

Abstract: The invention relates to an apparatus for spreading a fluid onto a moving web of material, especially for spreading size onto a paper web. It is previously known to spread fluid substances onto a moving web of material by means of a comb nozzle. Especially when size is being spread, the size tends to harden during stoppages, thereby clogging the openings of the comb nozzle. The apparatus according to the present invention enables a fluid to be spread onto a moving web of material without the apparatus getting clogged even in a dusty environment. By means of the apparatus it is possible to spread even rapidly drying fluids without the risk of the substance being spread drying in the nozzle opening or openings during stoppages. The apparatus has an oblong trough, on the circumference of which there is longitudinally an oblong opening and inside or adjacent to the trough a pipe parallel to the longitudinal direction of the trough, the pipe having on its circumference, also longitudinally, one or several openings over a maximum distance of the length of the opening of the trough in order to spread the fluid which is in the pipe via the openings onto a moving web of material, and means for feeding into the pipe the fluid to be spread. In addition the apparatus has means for feeding another fluid and/or a gas into the trough and for removing it from there, and means for transferring the opening or openings of the pipe so as to have connection with the inside of the trough.

Abstract: Process and apparatus for automatically producing a fabric with aligned nap zone and napless zone includes a conveyor along which the fabric is transported in such a manner that its nap zone is located at one side of a press pad and the napless zone is located under and at the other side of the press pad. A clamping device can be lowered on the napless zone to pull the latter transversely to the conveying direction of the fabric so that the edge of the nap zone is forced towards the press pad and to be aligned parallel thereto. Through cutting the napless zone in conveying direction after the nap zone is urged to lie against the press pad parallel to the edge of the nap zone an exact alignment of the napless zone to the nap zone is achieved.

Abstract: One arm (8) of the stirrup extends into an arm-connecting part, and the other arm (11) projects outwards from that part. The L-shaped part (7) attached to the stirrup (6) has its arm connected at its free end by a spring (25) to the adjacent stirrup arm so that the spring, via the L-shaped part connector (17), loads the ends of the stirrup arm and that of the L-shaped part against one another. The arm ends carry brake shoes (1) which are spring-loaded against each side of a rotating plate (2) connected to the pivoting structure drive motor. The thus produced braking effect can be cancelled by a magnetic coil (34) which attracts an armature (32) connected to the arm of the L-shaped part projecting out of the stirrup. This armature is connected to another (29) which is attracted by a magnetic coil (27) in the spring loading direction.

Abstract: A coater for coating a running paper or cardboard web comprises a coating chamber having one side open against the web and means for filling the coating chamber with pressurized coating substance. The coating chamber is limited in the longitudinal direction of the web by a web entrance wall, and opposite thereof, a back wall in the form of a doctor member for forming a coating layer on the web. The distance between the walls is so short that, at normal web running speed, the web moves from the web entrance wall to the back wall in a time of at the most 0.3 s, preferably at the most 0.03 s. Coating substance is supplied by means of positive pressure to the coating chamber at a position close to the web entrance wall. Close to the web entrance wall the flow of coating substance in the coating chamber is divided into two branches, of which a first branch follows the web in its running direction towards the back wall and a second branch, which is considerably greater than the first branch, flows out from the coating chamber through a slot between the web entrance wall and the web.
