Patent SE-7809961-L (SE)
Inventor: ADOLFSSON M
IPC: G01R15/22
Filed: 1978-09-22
Abstract: A measuring device has a transmitter side that is connected to a receiver side over an optical transmission link. The transmitter side receives an input measurement signal from a transducer and applies the input signal to an adder that also receives a feedback signal from the receiver side. The adder generates a comparison signal that corresponds to the difference between the input signal and the feedback signal. The comparison signal is applied to a regulator on the receiver side. The regulator generates the feedback signal and an output signal having a magnitude corresponding to the magnitude of the input signal. Amplification of the feedback signal on the receiver side is controlled by time division or frequency division calibration signals, so that the total amplification of the feedback signal between the adder and the regulator is held constant.

Abstract: In a capacitive coin detector capacitor electrodes (3, 4) connected to an electric circuit for detecting capacitance variation during the passage of a coin (5), are arranged on a rearwardly inclined wall (1) of a sloping coin chute having a coin support rail (2). One or more first electrodes (4) are located on the wall (1) in such a manner that the edge of a coin (5) in the chute overlaps said electrode a little or not at all, dependent on its size. A further electrode (3) is located to be closer to the centre of the coin path and has a considerable area. In this manner the capacitive coupling between the electrodes (3 and 4) via the coin (5) is substantially determined by the coin overlap of the first electrode(s) (4). With the first electrodes (4) located at the upper edge of the coin, the coin diameter can be directly checked. When they are located at the lower edge of the coin in a coin chute, where the coin support rail forms an angle of less than 90 DEG  with the wall, it is possible to check the coin thickness. <IMAGE>

Abstract: In order to make optimum use of the available transmission channels in an information transmission system, such as a trunked mobile ratio transmission system, where a number of uncoordinated users may wish to signal to a central control point in addition to using the channels for another purpose, the central control point monitors the channels and, when a channel is or becomes free, sends a command signal on that channel. When a user who is waiting to signal receives the command signal he chooses one of a predetermined number of immediately following time slots in an effectively random manner and sends his request in that slot in digital message form. The central control point sends an acknowledgement in the next time slot if and only if it receives the request in an error-free manner. If a user does not receive such an acknowledgement in response to the transmission of such a request he tries again when he receives the next command. The channel is used for other purposes, if necessary, at times other than those occupied by a command signal plus the subsequent predetermined number of time slots. If requests from more than one user should clash in the same time slot they will not be received by the control point in an error-free manner, this being determined by means of error check bits provided in the request message.

Abstract: The procedure of this invention for non-destructive testing of spot welds is based partly in the creation of a low-frequency electromagnetic primary field in the zone in front of the spot welding core. The field induces eddy currents in this zone, and in part determines the phase of the resulting low-frequency electromagnetic field's strength in this zone, and also creates a high-frequency electromagnetic primary field in the spot-welding zone. The field induces eddy currents in this zone, and in part determines the phase of the resulting high-frequency electromagnetic field's strength in this zone, and thereafter determines a difference between the resulting high-frequency electromagnetic field's strength phase and the resulting low-frequency electromagnetic field's strength phase and appreciates the quality of the spot welding core as directly dependent on the phase difference.The device for non-destructive testing of spot welds includes a current converter (1), a low-frequency measurement channel (22), a high-frequency measurement channel (18), and an indicator (28). The device also includes a directional coupling device (30) which is designed to alternately couple the converter (1) into the low-frequency measurement channel (22) and the high-frequency measurement channel (18), a memory unit (26) which is designed to store the output signal from the high-frequency measurement channel (18), a comparator (27) and control (29). The comparator (27) is designed to compare a signal stored in the memory unit (26) with the output signal from the low-frequency measurement channel (22), while the control (29) is designed to alternately create signals to simultaneously couple the converter (1) into the high frequency measurement channel (18) and lower signal from the measurement channel (18) in the memory unit (26) as well as signal to simultaneously couple the converter (1) into the low frequency measurement channel (22) and compare the signal from the low frequency measurement channel (22) with the signal stored in the memory unit (26).This invention can be used in the machine, ship, construction, aviation, and automotive industries for fault tracing and a non-destructive testing of a change in properties in the material of metal constructions of varioustypes.

Abstract: A gripper tractor assembly is provided for selectively grasping, conveying and releasing newspapers and like products in a high speed transit path between processing stations. Its structure comprises two jaws pivotable about a common pivot pin for movement between open and closed jaw positions by means of a cammed lever assembly and equipped with rollers for engaging a transport tract defining its travel path. Alignment of the products is assured by a pair of separated stops against which the paper is positioned and gripping means centered therebetween. The papers are gripped by a rubber-like O-ring mounted on an arm extending from the gripping edge of one jaw as the edge is abutted against the stops in self-aligning fashion. The tractors are positioned at precise spacing along a link chain for movement therewith. Removable attachment means for the carriage includes an L-shaped chain link, which permits removable bolt coupling of the carriages to the link chain for eash maintenance and installation. To avoid stresses tending to release the clamping action of the jaw or to misalign paper products during transport, the jaws hold the papers against a platform surface holding the papers at an angle to the transport axis in natural position for shingling to avoid bending or stresses.
