Patent EP-0423831-A2 (EP)
Inventor: GEORGOPOULOS GEORGE
IPC: G09F3/03
Filed: 1990-10-20
Abstract: An improved security seal includes a plastic housing (22) with a chamber open at one end and a plastic rotor (24) which is insertable in the chamber. The housing wall contains bores (42, 44) aligned across the chamber and two annular grooves (38, 40) adjacent the chamber entrance. Tabs (56, 58) are formed adjacent the chamber entrance. The rotor has a bore and two annular ridges (70, 72) near its top. The ridges (70, 72) are relieved complementarily to the tabs. The rotor may be partially inserted in the housing by snapping the lower ridge (72) into the upper groove (38) and locating the tabs in the relieved areas to align all of the bores so that a seal wire (26) may thereafter be inserted through the seal. The ridge-groove and tab-relief cooperation prevent inadvertent relative rotation of the rotor and housing and full insertion of the rotor. With a seal wire (26) inserted, the rotor (24) and housing (22) are relatively rotated to wrap the wire about the rotor (24). The rotor (24) is then fully inserted into the housing (22) so each ridge snaps into one groove. This and the engagement of teeth (34) on the bottom of the rotor and the chamber prevent removal of the rotor (24) from the housing (22), relative rotor-housing rotation, and removal of the wire from the seal. Cowls may surround the housing bores to obviate insertion of an object and levering out of the rotor from the housing.

Abstract: Method and apparatus for identifying a valid symbol or a string of valid symbols from a sequence of handwritten strokes. A method includes the steps of (a) generating in response to one or more handwritten strokes a plurality of stroke labels each having an associated score; (b) processing the plurality of stroke labels in accordance with a beam search-like technique to identify those stroke labels indicative of a valid symbol or portion of a valid symbol; and (c) associating together identified stroke labels to determine an identity of a valid symbol or a string of valid symbols therefrom. An aspect of the invention is that each of the constraint validation filters is switchably coupled into a serial filter chain. The switches function to either couple a filter input to a stroke label or decouple the input and provide a path around the filter block. An application writer has available a plurality of constraint filters. The application writer specifies which one or ones of the constraint filters are to be applied for a specific sequence of strokes.

IPC: H04L12/433
Filed: 1990-09-04
Abstract: A multi-frame stripping method for use in a token ring network utilizing early token release with multiple frames transmitted by multiple stations circulating around the ring. The method recovers the ring with minimum loss of data after detection of an error condition resulting in frame corruption. The transmitting station (10) is re­sponsible for removing its own frames from the ring. With one or more of its frames corrupted, a station (10) termi­nates frame removal after the transmitter has finished transmitting when a frame is received from another station without code violation errors in the frame header if a frame counter (80) has returned to its initial value. The station (10) terminates stripping when only a single frame is transmitted and then becomes corrupted if an isolated ending delimiter is detected at the station. The station (10) also terminates stripping in the multi-frame case when the ending delimiter of the last frame transmitted by the source station is received without code violation error in the I-bit, if each preceding ending delimiter is correctly detected regardless of data corruption occurring in any frame header.

Abstract: In order to drive a stepping motor (1, 2) which can be driven in main steps and in intermediate steps within each main step, the motor (1, 2) is driven into a defined zero position for starting, using a phase current combination which corresponds to the defined position. Thereafter, a test is carried out via a reference switch (4, 5) which is arranged between the mutually moving motor parts (1, 2) to determine whether the motor (1, 2) is in the defined position. The defined position is reached when the reference switch (4, 5) triggers. If said switch does not trigger, the motor (1, 2) is driven so that it carries out a movement whose magnitude is equivalent to a plurality of main steps and is then once again driven with the abovementioned phase current combination. The reference switch (4, 5) is then interrogated again. This is repeated until the reference switch (4, 5) triggers and the defined position is hence reached. <IMAGE>

Abstract: A device for extracting a liquid or pasty mass from a tube (14) has a handle (12) and a key (10) with a hollow shaft (11) which is provided with a longitudinal slot (13) which widens and is open at the end. The end of the tube (14) is gripped in that it is introduced from the open end into the longitudinal slot (13). The hollow shaft (11) of the key (10) with the tube end is pushed from one side into a longitudinal, horizontal recess (8) which is formed by a depression (4) in a base plate (2) of a holding device (1) and a clamping plate (3) which is made of elastic material and projects beyond said holding device. On the underside, the recess is bounded by a shoulder (5) which, with a curve (7) of the clamping plate (3), forms a clamping slot (9) through which the tube (14) is passed. By turning the key (10), the tube (14) is pulled through the slot (9) into the recess (8) and rolled up. During this process, or in the case of pressure on the tube (14), the mass is delivered from an outlet slot (16) in a closure cap (15) made of rubber. <IMAGE>

Abstract: A gauge for measuring a change in the spacing between two locations has a support that is fixed at one of the locations and a wheel pivotal on the support about an upright axis and having an outer periphery. The wheel periphery and the support have juxtaposed portions one of which is provided with a pointer and the other of which is provided with a scale so that the pointer moves along the scale as the wheel pivots on the support. A flexible belt has an inner end anchored on the support, a middle portion, and an outer end attached at the other location. This outer end is releasably fixed to the wheel periphery and a spring urges the wheel rotationally on the support in a direction pulling the middle belt portion taut between the locations. Thus as the two locations move relative to each other the pointer moves relative to the scale.
