Patent SE-336005-B (SE)
Inventor: SEEMANN D
IPC: H04Q3/52
Filed: 1967-04-05
Abstract: 1,126,845. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 6 April, 1967 [8 April, 1966], No. 15790/67. Heading H4K. In a current controlled, self seeking switching network in which calling lines are connected to free links during time slots allocated to these links, in the event that the originally reached link is unsatisfactory for the type of call required, the path to this link is dropped and after a short delay to allow transients to subside another path to a more suitable link is set up. The normal links 32 viz those first reached by calling lines, are primed in TDM manner by an allotter 23 and a calling line is connected to a primed link via a PNPN network 20 in normal manner. Thereafter the link is connected via auxiliary network 37 to a register which causes dial tone from a common source DT to be reverted via the link to the caller. After receipt of all the dialled digits the register sends signals, to the link so that it can be primed during the next occurrence of its time slot, to a call enable circuit which inhibits all lines (except the called line) from marking its end of the network and thus gaining unwanted access to the primed (but semi-busy) link and, to the called line so that it can mark its appearance on the network. When the called side of the connection is complete the register authorizes the transmission of ringing tone and then withdraws. If the called party is busy the register starts a busy tone generator B T . If the dialled digits indicate an outgoing call or a special service e.g. tie line trunk, conference call, centralized dictation, public address, conversation timing, &c. or if the class of service of the caller or called party warrants it (such class of service may be: code-calling, key sending, restricted service, camp-on busy &c.) then the register seizes a features link 35 and when the time slot of the original link occurs the allotter 23 is stopped (using logic 62, 63 and clock 57), the original path is dropped and, after a pause, a new path to the features link is set up. The pause is effected by gating on transistor 54 of pulse 71 which occurs during time slot t1 of the original link. PNPN diode 52 which is connected via diode OR gates to each line circuit has a lower breakdown potential than any switching network diode so that when the original path is released and the calling line produces a calling potential, this diode conducts via transistor 54 so as to clamp the calling potential to its own breakdown potential. After a time sufficient to allow network transients to die down, transistor 54 is turned off whereby the calling potential can rise in ramp fashion and hence eventually fire a path through the network to the features link. Completion of a path to this link results in a signal for restarting the allotter. It may be noted that features links are not governed by the allotter.

Filed: 1979-06-28
Abstract: A non-occlusive, non-adherent dressing for wounds, the dressing comprising an imperforate (i.e. continuous) flexible film (10, 12, 14) for contacting the wound, and an absorbent pad (16, 18) backing the wound-contacting film (14) and extending beyond a substantial portion of the periphery (20) of the film (10, 12, 14), the dressing having vapor transport capacity approximating that of intact human skin. The absorbent pad (16, 18) removes wound exudate from the proximate area of the wound without the pad (16, 18) coming into contact with the open wound itself. The final construction, comprising the film (10, 12, 14) and absorbent backing (16, 18), permits a measurable amount of moisture vapor to be transmitted (greater than 0.06 mg/cm<sup>2</sup>/hr), thereby greatly reducing the degree of maceration and other problems that may be produced by a fully occlusive dressing.

Title: Butter spreads
Inventor: LANTING-MARIJS JACQUELINE ADRI
IPC: A23D7/015
Filed: 1990-04-20
Abstract: Butterfat spreads include products with around half the fat of butter. Around 15-20% of the fat-phase in butter is solid at 20 DEG C. When butter is placed in the mouth this fat melts, produces a cool sensation on the palate. Low fat content attenuates the cool-melting properties, while adding stearins to the product can cure the mouth melt problem but gives a product which is hard when removed from the refrigerator. The specification discloses a low fat butter spread in which the distribution of stearin in the product is inhomogeneous such that the C/N*N at 10 DEG C is less than 0.35. This spread is cool melting without being hard at fridge temperature. The specification also discloses a process comprising the step of mixing of a pre-crystallized viscous butter stearin cream, having a gelled or thickened aqueous phase, with a fat-continuous emulsion of whole butterfat and water, preferably in a 30:70 ratio, to obtain these products. Preferably the aqueous phase viscosity of the butter stearin cream is greater than 50mPa.s at 20 DEG C as measured at a shear rate of 181 rpm after a resting period of 30 min.
