Abstract: A latch has spaced inner and outer plates formed with respective coaxial bores. The outer plate is formed at its bore with at least one notch and the inner plate is formed adjacent its bore with at least two angularly offset and axially extending cutouts. A plug extending through the bores and rotatable therein about the axis has an outer head in the outer bore and accessible from outside the plates and an opposite inner end exposed inward past the inner plate. A locking dog extends radially from the plug in the space between the plates. An inner abutment washer is secured to the inner end of the plug and spaced axially inward of the inner plate and a retaining washer angularly nondisplaceable on the inner end of the plug has a bump engageable in the cutouts of the inner plate. A compression spring braced between the washers urges the bump into the cutouts. A key engageable with the plug head has a radial tab complementary with the notch of the outer plate. The plug with the pawl and retaining washer are angularly displaceable about the axis between a locking position in which the tab and notch can interfit and the bump of the retaining washer engages one of the cutouts of the inner plate and a freeing position in which the tab and notch cannot interfit and the bump of the retaining washer engages the other cutout of the inner plate. A formation on the inner end of the plug is shaped to be engaged for rotation of the plug from inside the inner plate.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are described for folding a sheet, such as a map sheet, made of stiff paper or plastic, which is star-folded, in which the outward and inward folds that meet at the centre point of the sheet are formed simul-taneously by V-shaped carriers.  First folder elements can be swung upwards perpendicular to the carriers and when the two halves of the sheet are folded together, the inward cor-ner folds are made by second folder elements that are arti-culated onto the side edges of the carriers and swing down on these.  The two folded halves of the sheet are then pres-sed together between the carriers, the clamping plates and the second folder elements before the folded sheet that has been folded together is grasped by the gripper and withdrawn between these plates after the pressure on the designated plates has been released.

Abstract: ABSTRACT OF THE INVENTION      A tactile sensing apparatus having a piezoelectric energizing layer with a plurality of conductors disposed on one surface of a piezoelectric material and a plurality of conductors disposed on the opposite surface of the piezoelectric material, the plurality of conductors having electrical connections connected to electrical energizing means.  An electrical insulating layer is disposed adjacent the piezoelectric energizing layer.  A second piezoelectric sensing layer is disposed adjacent the insulating layer, and has conducting surfaces disposed on opposite surfaces thereof.  The conductors in the piezoelectric energizing layer provide N x M energizing areas with N + M electrical connections to the energizing layer.  Further apparatus may include an oscillator, an optional amplifier and a switching means or multiplexer for the input signal.     The apparatus may optionally have more than one piezoelectric energizing layer as well as more than one piezoelectric sensing layer.  PVF2 is the preferred piezoelectric material.  An optional base material and protective layer may be used.     A method of operating the tactile sensor includes providing a variable frequency electrical signal at a frequency and amplitude adapted to energize the energizing areas.  The signal is switched to the conduc-tors to energize selected energizing areas of the energizing layer in a predetermined sequence.  The signal generated in the sensing layer that varies in frequency and amplitude in response to an object in contact with the tactile sensor is processed for frequency and amplitude information to determine the characteristics of the object such as shape, force or weight.

Abstract: ABSTRACT OF THE DISCLOSURE            The contact apparatus has at least two contact bodies and at least one segmented body. The latter possesses bars separa-ted from each other by slots and having a curved central area. Furthermore, the bars have the form of a three-dimensional curve. In their end areas, the bars possess in each case a section curved in the opposite sense to said curved central area. Besides, the bars are linked together at their ends by means of edge strips . Moreover, the slots extend up to the curved section. In this way, points of con-tact clearly defined as regards their position and values are assigned to the convexity as well as the end areas of each bar. These measures lead to an improvement of the mechanical and electrical characteristics of the contact apparatus.

Abstract: ABSTRACT         A voice and data transmission system includes data circuit terminal equipment (DCE) connected between a subscriber's telephone equipment and data terminal on the one hand and one end of a telephone line on the other hand.  The other end of the tele-phone line is connected to office channel equipment (OCE) also connected to a telephone exchange and data gathering equipment.          By known multiplexing and demultiplexiny techniques voice and data signals can be transmitted along the same line.  When power is deliberately or by reason of a fault removed from DCE relays come into operation to by-pass the main parts of DCE and OCE thereby permitting voice communication above.  When power is restored, this is sensed and the by passes are removed so that normal operation of DCE and OCE is resumed.

Abstract: ANNOUNCING WAITING TIMES                   IN QUEUING SYSTEMS     Abstract In an automatic call distributor system, calls waiting in a queue to receive attendant service are informed of the expected waiting time prior to connection to an attendant.  This permits callers to defer a call if the queue is excessively long and they can place the call at a later time.  The announcements are periodically updated to reassure customers that they are, in fact, progressing in the queue.  Customers are given the opportunity to leave a message such as a telephone number if they do not wish to wait.  Advantageously, such an arrangement avoids a situation wherein a customer impatiently disconnects just before being served or waits too long unexpectedly because of absence of information on remaining waiting time.

Abstract: A dispensing system for the sustained releasing of a substance at a substantially constant rate includes semipermeable capsules containing a material to be released. The capsules comprise membranes having pores of dimensions sufficient to control the kinetics of release provided there is maintained a large intracapsular concentration of the substance relative to the concentration desired in the extracapsular environment. The system may be produced by forming permeable capsules, suspending the capsules in a solution containing a high concentration of the substance to load the intracapsular volume, and then post-treating the capsules to reduce the size of the pores.
