Patent EP-0360732-A2 (EP)
Inventor: GORDON RICHARD J
IPC: H04N1/32
Filed: 1989-09-22
Abstract: A system and method for facilitating facsimile transmis­sions has one or more store and forward facilities, each asso­ciated with a plurality of subscriber facsimile machines, typ­ically coupled over the switched telephone network. The store and forward facilities include a computer for controlling operations and mass data storage equipment. A subscriber to the system delivers an outgoing facsimile message to the store and forward facility with which it is associated, which rec­ords the fax message together with data as to originating fac­simile machine and destination facsimile machine. The store and forward facility then delivers the facsimile message to the intended receiver facsimile machine, either directly or through another store and forward facility. If unsuccessful on an initial attempt, the store and forward facility periodi­cally retrys to send the facsimile message. The system also provides spooling of all facsimile messages for an intended receiver machine, which are all transmitted upon making con­nection with the receiver machine. Subscriber mailboxes are provided as part of the mass storage, which can be accessed by a subscriber to have his messages delivered to any facsimile machine he designates. Secure facsimile transmission is achieved through use of subscriber PIN numbers. Broadcasting, redirecting messages and cost accounting can also be achieved by the system and method.

Abstract: An apparatus for butt-welding structural plastics elements is equipped with element clamping units (2, 3) which can be displaced relative to each other and a heated tool (15), which can be introduced between the end faces of two elements to be welded, the clamping units (2, 3) comprising weld limiting gauges (2b, 2f, 3b, 3f) which are directed parallel to the end faces of the elements and can be set on the latter. 
<??>To allow welding to be performed particularly efficiently and at the same time allow exactly matched welded joints to be produced, the clamping units (2, 3) are intended for receiving two elements (U, O) lying one above the other and have in addition to the outer limiting gauges (2b, 2f, 3b, 3f) an intermediate limiting gauge (5, 6), which can be placed between the elements (U, O) and is supported with resilient compliance in the clamping direction of the elements and in such a way that it can move with the clamping units (2, 3) in the direction of displacement.

Abstract: The fire-proof door is formed from a box-shaped door leaf (1) which encloses mineral-fibre panels (5). The visible sides of the door leaf (1) consist of two cover plates (2, 3), and the end faces are formed with a frame (4). A gap between edges (6) of angled edge strips (7) of the cover plates (2, 3) is bridged by the frame (4). Longitudinal edge strips (14) of the frame (4), which are angled in the interior of the door leaf (1), engage in grooves (15) provided in end faces of the mineral-fibre panels (5). The profile of the frame (4) is provided in its central region with a groove (8) which is open to the outside and in which are provided a strip (10) which foams under the action of heat, and a plaster channel (11). The frame (4) holds the mineral-fibre panels (5) at a parallel spacing, so that these parts form a compact, pre-manufacturable construction unit to which the cover plates (2, 3) can be positively attached at both sides. <IMAGE>

Abstract: The present invention provides a method for producing expandable thermoplastic polymer particles which comprises conducting polymerization by adding a polymerizable monomer either continuously or intermittently to thermoplastic polymer particles having a uniform particle size suspended in water,characterized in that an amide compound is added when the added amount of the polymerizable monomer is not more than one half of the total amount to be added in the course of polymerization and resulting polymer particles are impregnated with an easily volatile blowing agent after completion of addition of the amide compound and the polymerizable monomer. According to the present invention, expandable thermoplastic particles which are capable of giving cells, fine and uniform in size, are obtainable even by expanding immediately after production without any aging period.

Abstract: A new composition of titanyl phthalocyanine is provided. This composition has in its infrared absorption spectrum characteristically strong absorptions at absorption wavenumbers (in unit of cm-') of 1490 ± 2, 1415 ± 2, 1332 ± 2, 1119 ± 2, 1072 ± 2, 1060 ± 2, 961 ± 2, 893 ± 2, 780 ± 2, 751 ± 2 and 730 ± 2, and has an extremely high solvent stability and dispersibility, and a large photoelectric conversion efficiency. The new form of composition can be obtained by adding to titanyl phthalocyanine, compounds of other phthalocyanines or naphthalocyanines as additives, and treating the amorphous composition of the mixture to crystallize the composition. By applying an appropriate binder, with the novel composition crystals as a charge generation agent, on a substrate, it is possible to obtain an electrophotographic photosensitive material that has a charge generation layer with an extremely high dispersibility and an extremely large photoelectric conversion efficiency.

Abstract: A countersunk head screw, intended in particular as a window installation screw, has a thread 15, extending up to the countersunk head 12, on its thread shank 11. The countersunk head 12 is constructed from a first wedge-shaped section 16 which is adjacent to a second, markedly flatter, section 18. The opening angle of the first truncated-cone-shaped section 16 corresponds to the opening angle of normal countersunk head screws, but it has a shorter length, seen in the longitudinal direction of the screw. In consequence, the overall length of the countersunk head 12 is reduced and the thread 15 can roll completely to a point closer to the countersunk head end of the screw. <IMAGE>

Abstract: In a switch device for the electrical change-over switching, namely the switching-on or -off or rotation direction reversal, of electric tools, especially of electric hand tools such as drilling machines, grinders and the like, it is proposed to arrange on the outer cylindrical housing of the electric tool a rotatable adjusting ring which is positioned at the level of the B-bearing plate of the electric motor arranged within the housing such that the adjusting ring can grip a rotatable plate or a switching ring on the electric motor by means of inwardly pointing projections, and, together with said motor, can then carry out a rotary movement to switch the electric motor on or off and/or to reverse its direction of rotation when the outer adjusting ring is subjected to a manual rotation. The adjusting ring can advantageously be provided with an automatic reset, implemented by means of spring pretension, into an original position, with a releasable locking device which holds the adjusting ring in the deflected angular position.

Abstract: A phase locked loop circuit is arranged such that the frequency of an input reference clock signal (CK MS ) is selected on the basis of a first or second transmission rate of an incoming digital signal (S in ), whereby an output digital signal correctly synchronized with the incoming digital signal having the first or second transmission rate can be transmitted. Also, the phase locked loop circuit is arranged so that a first or second central frequency value and a first or second boundary frequency value are set in response to the first or second transmission rate of the incoming digital signal so that, if a frequency value of an output digital signal lies outside of a range of the first or second boundary frequency values, the frequency of the output digital signal is set to the first or second central frequency values. Thus, the phase locked loop circuit of the invention can deliver the output digital signal correctly synchronized with the incoming digital signal having the first or second transmission rate.

The apparatus comprises: a pattern generator to generate pattern data; a memory to store the pattern data generated from the pattern generator as a font cache; and a controller for controlling in a manner such that when a residual amount of the memory is less than a capacity enough to store other data which is newly input and whose priority regarding the storage is higher than the priority of the pattern data, the pattern data of the font cache is deleted and the newly input data is stored. An auxiliary character font, form data, or a macro instruc­tion is used as data which is newly input. The pattern data of the font cache in the memory is deleted on the basis of the priority. The pattern data is a dot matrix font pattern which was developed from a nondot matrix font.
