Abstract: The invention relates to an arrangement for transmitting an indication signal 7b; 107b between the video equipment of two telephone subscribers. The symbol is to appear in an identical position on the subscribers' video screens. According to the invention, the subscribers each have their own equipment for this purpose. This equipment comprises a memory 7a; 107a containing a pattern for the symbol, a counting device 11b, 14; 111b, 114 which traces the coordinates of the image beams on the video screen and a registration device 8, 9; 108, 109 in which the required coordinates for the symbol can be entered. A comparison circuit 12, 15; 112, 115 compares the content in the counter and in the registration device. In the event of agreement, the comparison circuit emits a signal that starts the reading off of the pattern in the memory. A mixer circuit 18; 118 mixes the signals from the memory with the video signals that are displayed on the screen. At least one subscriber has a writing device 16, 17 in order to be able to write in his register the required position for the symbol. A transmitting device 19, 22; 119 between the subscribers transmits the information about this position to the registration device of the second subscriber. <IMAGE>

Abstract: Communication between portal units and identification tags is accomplished by continually radiating an interrogation signal consisting of a code pattern from each portal unit followed by a listening interval. Tags within range of such interrogation signal test the incoming signals for frequency, bit duration, bit rate, a preamble code and a facility identifying code. If the tag receives a valid signal to which it has been preprogramed, such signal synchronizes and initiates a plurality of tag responses within a given overall response interval and with each response transmitted during randomly selected time slot. Each tag is provided with its own pseudorandom binary sequence generator and reply counter with the pseudorandom generator sequenced by a signal derived from the carrier signal radiated by the tag. The portal units also test incoming signals for frequency bit rate and bit duration as well as for a preamble code generically indicative of a tag. If the test is passed, the remaining tag response consisting of an identifier and an error correcting code is accepted and passed on to a CPU.

Abstract: A tensile force indicator for measurement and indication of tensile force in a fixed-end wire or continuous wire. The indicator (5) consists of a flat bar that is turned around its longitudinal axle and two coaxial sleeve components (10) surrounding the bar. These are equipped with interactive indicator devices (12, 13, 14, 15) and are non-rotational and are connected to each end (7, 8) of the bar. The ends (7,8) are provided with fixtures (6') for the wire and an adjustment device for adjusting the clamping force. A change in this would result in a change in the length of the bar and a relative rotation between both its ends (7, 8). This rotation is indicated by a displacement between the indication devices (12, 13, 14, 15) and the sleeve components (10).<IMAGE>

Abstract: A hydraulic device for controlling the knee-joint function in a leg prosthesis has a cylinder which is divided into first and a second cylinder parts adapted to be fixed to the lower leg of the prosthesis, and a piston rod which carries one piston in each cylinder part and is fixed to the upper leg of the prosthesis. The pistons divide the interior of the respective cylinder parts into two chambers. The adjacent first chambers of the cylinder parts are interconnected by a throttle device. The two, second chambers are also interconnected. One piston has a sealing member which is of a single-acting type to allow leakage of hydraulic fluid from the second chamber to the first chamber when the piston is moved in a direction reducing the volume of the second chamber, while it is completely sealing when the piston is moved in the opposite direction. A connection is provided between one of the first chambers and one of the second chambers. A pressure relief valve is arranged for opening this connection when the pressure of the hydraulic fluid in the one first chamber exceeds a predetermined value.

Abstract: An automatically operating apparatus is disclosed for applying webs of rubber or similar lining material of predetermined width and length to expanded surfaces of walls of steel in vessels, reactors or apparatus and for pressing said webs thereagainst, with said apparatus comprising a guide frame for a drivable carriage and with said guide frame being easily mountable to follow surfaces of different lengths. Mounted on said carriage is an unwinding means for the web material as well as a drivable position and press head adapted to be moved in the longitudinal direction of said carriage. The assembly is such that during operation, said press head is caused to steadily move along a zick-zack path and, in the course of unrolling said web material from the supply reel, said head positions said web portion against the surface to be lined progressively from left to right and from right to left and presses said web portion thereagainst at a constant predetermined pressure. By means of devices mounted on said carriage, application of the webs is accomplished simultaneously with the formation of a seam overlapping with the previously applied web and finishing treatment of this overlap seam and the preparation of the next overlap seam, which means, obliquely cutting the open longitudinal edge of the web.

Abstract: Radar apparatus for processing a received signal having a carrier frequency f0 includes means for directing the received signal in parallel into first and second channels. A first filter in the first channel bandpass filters the received signal and is centered at a frequency f1 equal to f0+ DELTA 1f. The first filter provides an output signal having a central frequency f0+ DELTA 1f/2. A second filter coupled in the second channel bandpass filters the received signal and is centered at f2=f0+ DELTA 2f. The second filter thus provides an output signal having a central frequency f0+ DELTA 2f/2. A first mixer in the first channel mixes the first filter output with a signal f1=f0+ DELTA 1f/2 to extract the carrier frequency of the first channel. Likewise, a second mixer in the second channel mixes the second filter output signal with a signal f2=f0+ DELTA 2f/2 to also extract the carrier frequency in the second channel. The ouputs of both mixers are then passed to a processing and exploitation device to manipulate the signals to arrive at the appropriate range and/or velocity information.

Abstract: A unique method for producing an anti-lacerative glass assembly wherein a plastic composite anti-laceration sheet (18) is to be bonded to a glass substrate sheet (14). The plastic anti-laceration sheet includes an inner layer of polyvinyl butyral (20) adapted to abut the glass substrate sheet, an intermediate layer (22) of polyester, and an outer layer (24) of abrasion resistant material. A glass cover sheet (30) having substantially the same curvature as the glass substrate sheet is utilized to press the anti-laceration sheet into bonding engagement with the glass substrate sheet. In accordance with the present invention, the bonding operation is accomplished by heating the laminated glass assembly a predertermined temperature in the range of 285<o>F to 305<o>F. It has been found that such a temperature must be sufficiently high to cause the intermediate layer of polyester to bond to the inner layer of polyvinyl butyral, and to cause the inner layer of polyvinyl butyral to bond to the glass substrate sheet, and must be sufficiently low to prevent crazing of the abrasion resistant coating. The present invention also concerns the use of a unique vacuum ring construction which is mounted about the periphery of the laminated assembly and is utilized to de-air the assembly. The vacuum ring (36) is provided with a check valve (38) to maintain the vacuum within the ring during periods wherein it is disconnected from a vacuum source. Further, the method of the present invention includes the step of removing a selected portion or portions of the anti-laceration sheet after it has been bonded to the glass substrate sheet to provide an exposed glass surface for use in mounting the glass assembly into an associated frame.

The spindle is capable of taking up four successive positions when it moves axially towards the third connection (18). Between the first and fourth connections (14,20) there is an internal axially extending threading (84), and the spindle (40) is firmly attached to an adjustable control (86) with limited axial extension.
