Abstract: 1338718 Negative impedance repeaters STANDARD TELEPHONES & CABLES Ltd 20 Aug 1971 39156/71 Headings H3T and H4R A negative impedance repeater comprises a first current path R 2 , R 5 , R 4  between the input and output terminals, a second and a third path including the emitter collector paths of complementary transistors T 1 , T 2 , impedances R 6 , R, higher than the input impedances of T 1 , T 2  being connected between the bases of T 1 , T 2  and the third and second current paths, respectively. The voltage vs. current characteristics of the repeater (Fig. 2, not shown), include an initial linear part as the input voltage rises from a small value, a negative impedance portion followed by a further positive linear characteristic as the transistors T 1 , T 2  increasingly conduct to a state of saturation. For linearity, the circuit is set to operate about the middle point of its negative impedance characteristics. Distortion may be further reduced by using two silicon transistors having their respective electrodes connected in parallel in place of each of the transistors T 1 , T 2  in conjunction with germanium biasing diodes D 1 , D 2  which may be single or paralleled pairs.

Title: Tampon for feminine hygiene and its production
IPC: A61F13/22
Filed: 1994-01-25
Abstract: A digital tampon (20) for feminine hygiene, having a round dome (33) and a recovery tape (24), consists of a blank which is shaped by winding up a length of continuous random fibre web and which is pressed to produce a preform having a fibre core, longitudinal ribs and longitudinal grooves. The longitudinal ribs are subsequently lightly pressed to the final shape of the tampon (20; 28). The preform, before being pressed to the final shape of the tampon (20), is shaped as a result of the separate, but simultaneous radial pressing of directly adjacent sectors of its entire circumferential surface to form a longitudinal groove and a longitudinal rib respectively on each sector of the circumferential surface. The fibre material is pressed radially to a lesser extent in the region of the end (22) provided with the recovery tape (24).

Title: Extended capability transfer between a user equipment and a wireless network
IPC: H04W8/24
Filed: 2008-06-30
Abstract: Techniques for transferring new capability information in an efficient and backward compatible manner are described. A user equipment (UE) may send a new capability indicator to a wireless network to indicate that the UE has new capability information to send. This new capability indicator may be implemented with a spare bit in an information element included in an initial message sent to the network. The network may request for the information or indicate that it can receive the information. The UE may then send the new capability information to the network upon receiving the request or the indication. Alternatively, the network may convey that it supports transfer of new capability information, e.g., via a broadcast message or a unicast message. The UE may then send new capability information at any time to the network, without having to send the new capability indicator.

Title: Use of pif peptide in the manufacture of a medicament for modulating the immune system
IPC: C07K/
Filed: 2012-07-17
Abstract: A novel class of embryo derived peptides are described (Preimplantation factor) that were generated synthetically and were tested on peripheral blood immune cells and shown to block activated but not basal immunity, inhibiting cell proliferation and creating a TH2 type cytokine bias, in addition PIF enhance endometrial receptivity by increasing adhesion molecules expression. PIF biological activity appears to be exerted by specific binding to inducible receptors present on the several white cell lineages. PIF peptides, which are immune modulators therefore may have diagnostic and non toxic therapeutic applications in improving fertility, reducing pregnancy loss as well may be useful when administered for the treatment of autoimmune diseases and for prevention xenotransplants rejection.

Lead oxide is modified into basic lead composition. Then lead-based ceramics powder is obtained by calcining this raw material in a range within 500 to 900 deg.C. Thereby the raw material powder of lead-based ceramics having a single crystalline phase can be produced by calcination at the comparatively low temp. The specific surface area of the obtained powder is made large and easiness of sintering property is obtained because the calcination temp. is lowered.
