Patent EP-0219326-A3 (EP)
Title: An absorbent article having dual cuffs
IPC: A61F13/15
Filed: 1986-10-10
Abstract: An integral disposable absorbent article such as a diaper having a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, at least one elastically contractible gasketing cuff, and at least one barrier cuff. The barrier cuff has a proximal edge and a distal edge. The absorbent article is additionally provided with spacing means for spacing the distal edge away from the top surface of the topsheet. In addition, adhesive means secure the end portions of the barrier cuff closed. A channel is formed between the proximal and distal edges in at least the crotch region because the distal edge is spaced away from the topsheet top surface.When the diaper embodiment of the present invention is applied to a wearer, the barrier cuff rides up along the inner thighs and the perineum of the wearer in the crotch region and along the buttocks in the back waist region. Leakage prevention is enhanced because body exudates which are not immediately absorbed by the absorbent core contact the barrier cuff and are contained and held within the channel so that they do not wick out of the diaper or flow out of the gaps between the diaper and the legs or waist of the wearer. Additionally, should such exudates flow beyond the barrier cuff, leakage is further enhanced by the gasketing cuff because it forms an additional fluid impervious barrier about the leg or waist of the wearer.
Patent EP-0235441-A3 (EP)
IPC: H03K7/06
Filed: 1986-10-28
Abstract: An oscillator produces an output signal which 
is frequency locked to a reference signal but 
phased locked to a triggering signal (YTRIG). The oscilla­
tor includes a NOR gate (12) having its output fed back 
to one of its inputs through a programmable delay 
circuit (14) while the triggering signal is applied to 
another of its inputs. When enabled by the 
triggering signal, the output signal of the NOR 
gate oscillates at a frequency inversely propor­
tional to the delay time of the delay circuit. The 
delay time is controlled by a control circuit which 
counts NOR gate output signal cycles occurring 
during a predetermined number of reference signal 
cycles and increments the delay time when the count 
is higher than expected for an oscillator output 
signal of a desired frequency and decrements the 
delay time when the count is lower than expected.

Title: Printing unit
IPC: B41K1/10
Filed: 1987-08-27
Abstract: A printing mechanism is described comprising a plurality of type carriers (12, 34) which on their outer peripheral face carry in one region printing types and in another region indicator types (44). The printing types can be brought by turning the type carriers (12, 34) into a printing position. A setting means (32, 20, 24) including an actuating knob (32) can be brought into a drive connection with each of the type carriers (12, 34) for rotation thereof. Stop means (100, 102, 104, 106, 110) limit the turning travel of the type carriers (12, 34). With a detent moment governed by their spring hardness resilient detent elements (96) hold the actuating knob (32) against a rotation relatively to the type carrier (12, 34) in drive connection with the setting means (32, 20, 24), the detent moment being greater than the torque necessary to rotate the type carriers (12, 34). A setting member (112) for influencing the spring hardness of the detent elements (96) can be brought into engagement with said detent elements (96).

Title: Method of manufacturing an artificial grass and an artificial grass obtained therewith
IPC: E01C13/00
Filed: 1987-09-14
Abstract: A method for manufacturing artificial grass consists of an underlayer and strip-like pile threads embedded therein, which threads protrude, as grass, on one side out of the underlayer, particularly for a sports field, for instance a football pitch. The object of the current invention is to make available a method which enables the manufacture of an artificial grass such that it meets requirements with respect to coefficient of friction/roughness.   Use can be made of frizzing or crinkles to obtain the isotropic properties of the turf. An effective lowering of the coefficient of friction can be realized in this way. Use can be made for this purpose of a circle knit method or knitdeknit. The crinkles can be fixed by a heat treatment. As an alternative substances may be added (mixed coated or coextruded) reducing the friction coefficient.

Title: Expander roller with or without an elastic coating
IPC: D06C3/06
Filed: 1988-12-17
Abstract: The object of the invention is to allow cooling emanating from the hollow space of the bent roller to be transferred evenly onto the outside of the expander roller. For this purpose, the hollow spaces inherent in the design are filled by a conductive material, preferably aluminium, in the form of a moulded part adapted exactly to the shape of the respective hollow space. This configuration achieves not only a more uniform cooling on the outside but also an approximately even film of condensate between the expander roller and the material to be dried. This film of condensate serves as a parting line between the expander roller and the material to be dried. <IMAGE>

Title: Method and apparatus for decoding reed-solomon code
IPC: H03M13/03
Filed: 1988-06-17
Abstract: A decoding method of Reed-Solomon code produces an error polynomial (x) and an error evaluation polynomial  (x) by a Euclidean algorithm, whereby a syndrome polynomial S(x) is obtained, the highest degrees of the syndrome polynomial S(x) and of an initial polynomial x<2t>, which is determined by the number t of symbols to be corrected, are multiplied, while the degree is incrementally reduced, thereby obtaining polynomials h(x) and g(x) that satisfy the relation:      f(x) B(x) + g(x) S(x) = h(x) (where the degree of h(x) is less than the degree of g(x)</= t). The polynomial g(x) is set to the error position polynomial  (x), and the polynomial H(x) is set to the error evaluation polynomial  (x), thereby performing the decoding by real time processing.

Title: Line interface circuit
IPC: H04Q3/42
Filed: 1988-09-05
Abstract: A line interface circuit supplies energizing 
current for operation of a two wire communication line and 
couples a.c. signals between the communication line and a 
telephone facility. Tip and ring rails (22, 23) are 
resistively connected to the communication line by matched 
feed resistors (12, 13) in a resistance network (10) also 
including tip and ring taps (6, 7). Active impedance 
circuits (130, 140) in an a.c. signal coupling circuit (100) 
terminate the tip and ring rails with a predetermined 
impedance, via the feed resistors, in response to voltages at 
the tip and ring taps. Active resistance valving circuits 
(220, 210) in a direct current feed circuit (200) supply the 
communication line with energizing direct current via the tip 
and ring rails and feed resistors. The valving circuits may 
be controlled to limit current for shorter lines and the 
functions of the a.c. signals coupling circuit may be 
optimally altered in response thereto. In one example, 
operating band width is extended into ISDN frequencies by 
providing a secondary resistance network (110) with secondary 
feed resistors (112 113) coupling secondary tip and ring 
rails (122, 123) to the tip and ring rails. In this 
structure, the a.c. signal coupling circuit is responsive to 
a.c. signals at secondary tip and ring taps (106, 107) for 
terminating the secondary rails and a supervisory circuit 300 
is responsive to the voltages at the tip and ring taps for 
generating supervisory signals for the telephone facility.
