Abstract: TELEPHONE SYSTEM                          ABSTRACT          An information transfer system is described for use in a telephone system wherein full duplex digital signal bursts containing a plurality of different types of information are transmitted between a central office and each of a plurality of subscriber locations, and wherein signals respectively containing the different types of information in a predetermined format are transmitted between the central office and each of a plurality of selected locations which may or may not be subscriber locations.  Signal processing circuits receive and disassemble the digital signal bursts into digital information words, each digital information word being comprised of only one of the types of information in the digital signal bursts.  The signal processing circuits also assemble digital information words of different types of information into digital signal bursts for transmission to respective subscriber locations.  Gateways are provided for each type of information for converting digital information words into a predetermined signal format for transmission to respective selected locations and for receiving signals in a predetermined format from selected locations and converting same into digital information words containing the respective type of information received.          A digital switch couples the signal processing circuits to the gateways for routing the digital information words from the signal processing circuits to a respective one of the gateways corresponding to the type of information in the digital information word being routed.  The digital switch also routes the digital information words from each of the gateways to the signal processing circuits for assembly into digital signal bursts for a particular subscriber location.  A control system is coupled to the signal processing circuits, the gateways, and the digital switch for synchronously operating same and for placing each of the digital information words in a preallocated time slot corresponding to the source and destination of the information contained in the digital information word.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of measuring the strength of concrete for the slip form process, to determine upward movement of a slide form so that the concrete placed in the slide form will be released therefrom after setting to a degree of strength capable of maintaining the shape of a structure to be constructed.  According to the method, an arithmetic unit calculates the temperature integral of the concrete placed in the slide form on the basis of measured data given thereto by a temperature sensor having a plurality of measuring elements and inserted into the concrete and by an altimeter that measures the position of the slide form.          The strength of the concrete is determined from the known relation between the temperature integral and the strength of concrete.

Abstract: COUPLING DEVICE FOR SINGLE MODE OPTICAL FIBER   AND COMMUNICATIONS SYSTEM COMPRISING SAME     Abstract Optical radiation can be efficiently removed from, or injected into, single mode optical fiber at an intermediate point along the fiber, by causing quasi-resonant coupling of the guided mode LP01 to an appropriate tunneling leaky (TL) mode, e.g., LP11.  Such coupling is caused by means of a "grating" in the fiber, with the grating being formed by impressing a periodic (or pseudo-periodic) modulation on the fiber, or by causing a periodic (or pseudo-periodic) variation of the refractive index of the fiber by means of the photoelastic or the photorefractive effect,  The nominal grating spacing ?(z) is chosen such that Oo = (2.pi./7?) > ?o1-2.pi.ncl?o, where ? is the average grating spacing, ?01 is the propagation constant of the LPO1 mode, ncl is the refractive index of the fiber cladding, and 1/O is the wavelength of the radiation to be coupled from or into the fiber.  Furthermore, ?(z) is to be chosen such that Oo   ?01 - ?rs, where ?rs is the propagation constant of the selected TL mode.  In order for the coupling to be quasi-resonant, it is necessary that .alpha.rs, the attenuation constant of the selected TL mode, be relatively small, typically < 1 dB/cm.  By appropriately choosing ?(z) and/or the amplitude function of the grating, it is possible to increase the coupling efficiency above what is possible with a constant spacing, constant amplitude grating.  Devices according to the invention can be advantageously used not only as radiation couplers but also as filters and, if they are of the photorefractive type, as amplitude modulators.

Abstract: Abstract of the Disclosure A surface-mount-technology repair station and method for replacing components on SMT circuit boards.  The station includes a base with a controllable heating element through which deionized air is blown onto the surface of a board opposite to the surface on which the repair is to be effected.  This raises the temperature of the entire board substantially but to a point below the melting point of solder.  A second heating element through which deionized air is blown is positioned over the leads of a selected component positioned on the board, that is either to be removed from or secured to the board.  The heating of the leads by the second heating element causes the solder on these leads to melt, thus, enabling replacement of the component.  To remove the component, the operator, using an instrument, such as tweezers, grasps the component and removes it from the board.  To install a component, the operator, after melting solder on the leads, discontinues the heating of the component.      The method of the present invention includes the steps of heating the surface-mount-technology boards to a substantially high temperture, and then heating the leads of a selected component to be replaced so that the solder disposed on the leads melts.

Title:       APPARATUS FOR MAKING A BAG WITH A BAG                MOUTH CLOSURE                    ABSTRACT           Apparatus for making a plastic film bag having bag mouth lips projecting beyond a heat-seal band closing the bag mouth and providing a stiffening patch bonded to the interior or exterior of a bag mouth lip between the heat-seal band and the bag mouth end for reclosing the bag mouth after the heat-seal band has been opened.  For reclosing  the bag mouth, the ap-paratus applies stiffening patches to a web of sheet material for making bags at the time that the bags are formed and filled by clipping from a strip of patch-making material patch pieces having pressure-sensitive adhesive on one side.  The apparatus transfers such patch pieces from a rotary shear onto the bag-making material by an orbiting transfer member having a suc-tion pickup to pick up a patch piece and blowing means for subsequently detaching the patch piece from the transfer member and depositing it onto the web of bag-making material.

Title: Coating web with viscous liquid
Inventor: DIPL-ING HERZHOFF PETER DR
IPC: G03C1/74
Filed: 1969-02-11
Abstract: Process comprises coating the web from below from a slit, the downstream wall of which defines a coating gap with the web at least twice the thickness of the required coating. To counteract web movement, there is an adjustable static pressure differential in the liquid between the inlet and outlet sides of the gap with the lower pressure at the inlet. The pressure differential is created by lowering the liquid level in a supply vessel relative to the level of the gap after coating has begun. Pref. liquid is fed to the supply vessel at the rate at which it is required to be applied, any difference in the rates automatically producing a change in level which eliminates the difference. Thus an even coating is applied independently of changes in, for example, liquid flow properties and web speed.

Abstract: In a system for wireless transmission of telephone calls between a stationary unit 1, which is connected to a telephone line 2 and a portable wireless telephone apparatus 3 at a short distance from the stationary unit 1, all pairs of appliances 1, 3 have access to a number of shared duplex radio call channels for the transmission of calls and a shared radio signalling channel for the transmission of signals concerning connection and disconnection of the call channels. The radio call channels are allocated in accordance with adaptive channel seeking in that they are monitored before a call and a free channel is selected. A single call channel is used for both call directions, which is made possible by time sharing and time compression. The degree of time compression can be set independently of whether or not there are speech signals to send. The system's radio transmitters are designed to transmit either digital or analogue speech signals. The system's radio receivers are designed to work in accordance with the homodyne principle. <IMAGE>
