Patent GB-578984-A (GB)
Title: Improvements relating to automatic telephone systems
IPC: H04Q3/00
Filed: 1945-01-01
Abstract: 578,984. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and LONG, D. P. Jan. 1, 1945, No. 30. [Class 40 (iv)] In a system using marker-controlled switches which, in accordance with a condition at a preceding switch, may advance to a second normal position before being controlled by the local marker, the same test relay is used to control both settings, the test circuit in the former case including a front contact and in the latter case a back contact of the dialling relay. If the switch is to have a preliminary setting, the line relay A pulls up in series with wiper-changing relay WS over the preceding loop, the latter relay being shunted out shortly afterwards by release relay B, which also energizes dialling relay C. This momentary operation of WS energizes the selector driving magnet MU which may operate as described in Specification 378,586. Magnet MU holds over off-normal contacts until its circuit is broken by operation of test relay T to a permanent ground connection in the marking bank, the circuit including c3 in the operated position. If preliminary setting is not necessary, the positive wire is grounded by the marker wiper M7 of the preceding switch and WS is therefore short-circuited when the selector is seized, and does not operate. Dialling impulses operate the marker in known manner, the latter over wiper M4 or M3 according as the selector was or was not driven to its second normal position operating relay WS to effect wiper switching if necessary and, on the relapse of C, the drive magnet MU operates and the switch hunts for a free outlet in the marked group under control of T in the ordinary manner, this test circuit including c3 in the released condition.

Title: Improvements in or relating to fine metal tubing such as is used for hypodermic needles
IPC: A61M5/32
Filed: 1943-01-01
Abstract: An elongated metal surgical instrument of fine dimensions, e.g a dental broach, hypodermic needle, &c., has an intrinsic fibrous or cane-like structure such that on bending sufficiently to cause p  the instrument to snap at the outer radius of the bend, it splits longitudinally so that the inner radius of the bend becomes substantial and does not snap.  The instrument &c. is preferably made by annealing a billet of metal, then cold-rolling or drawing it until the cross-sectional area is reduced by substantially more than 50% and then finally subjecting the metal to further heat treatment in the neighbourhood of 400 DEG  C.  In a further example, an austenitic nickel-chromium steel is first heated to about 1000 DEG  C., then cooled and cold-rolled &c. to reduce its cross-sectional area by from 80-98 per cent and subsequently heating the metal for a fairly long period at 350 DEG  C. or a shorter period at 475 DEG  C. The final heating may be arranged at about 400 DEG  C., 2 seconds duration being allowed for each 1/1000 " of cross-sectional dimension.  In a further example, a billet of austenitic nickel-chromium steel is first drilled, and then drawn until the bore is about 1/8 ".  A brass mandrel, first dipped in colloidal graphite, is then introduced into the bore and both are cold-drawn until the outside diameter of the tubing is about 1/32 ".  Both tubing and mandrel are then heated for 15 minutes at 400 DEG  C., and the tubing is then divided into lengths and removed from the mandrel which is not divided.  In a still further example, the initial billet may be formed from segments brazed or soldered together to form a tube which is drawn &c. as above.  The segments may be of different metals.  The original billet may, alternatively, comprise concentric tubes, the inner lining being of stainless steel &c.  Wires of high tensile strength may be embedded in the walls of the billet so that they become integral with the tube wall during drawing.  In a further modification, slots may be milled in the initial billet to give rise to the cane-like structure after drawing &c.  Specifications 210,156, 338,592, [both in Class 81 (ii)], and 507,003 are referred to.

Title: Varactor-transistor device for dynamic semiconductor memory
Inventor: KUESTERS KARL-HEINZ DR RER NAT
IPC: H01L21/82
Filed: 1995-01-19
Abstract: A transistor varactor for dynamic semiconductor storage means which are formed on a doped silicon substrate having an high integration density and which includes one field effect transistor which has source and drain and a gate and a varactor overlaps the gate electrode and is formed as a stacked capacitor. The gate electrode and the varactor are electrically isolated from each other by insulating layers and the contact of the source zone is electrically isolated from the gate electrode by the insulating layers and the upper polysilicon layer of the varactor formed by oxidation of the side portions of the polysilicon layer. The contact of the source zone adjusts to the gate electrode and to the polysilicon layer in that the distance of the contact of the source zone relative to the gate electrode and the polysilicon layer is independent of the photographic accuracy. A buried contact between the polysilicon layer and the drain zone is self-adjusted relative to the gate electrode.

Abstract: 1337134 Metal-vapour lamps GENERAL ELECTRIC CO 1 Jan 1971 [26 Jan 1970] 179/71 Heading H1D A high pressure metal halide lamp for vertical operation, which includes Hg and an inert starting gas and has an electrode sealed at each end of the discharge tube, is constructed asymmetrically such that more heat is generated and/or less heat is lost from the lower end of the tube so that the temperature of the lower end is substantially above 670‹ C' without driving the temperature of the upper end above 1000‹ C. This is achieved by having a smaller electrode 14a which generates more heat, and a heat reflective coating 18 of zirconium oxide at the lower end. In an alternative embodiment (Fig. 6a, not shown) the ends of the discharge tube which may be made of quartz or fused silica are constructed asymmetrically, the lower end being substantially conical and the upper end hemispherical. The outer envelope is preferably evacuated in small lamps (< 400 W) and has an inert gas filling in large lamps. A preferred filling for an arc tube of 18 c.c. volume and arc tube gap of 4 cm. includes: 90 mg Hg; 16 mg NaI; 0À9 mg TlI; and 0À16 mg InI. The mercury filling is preferably completely vaporized and there are excess halides present. Argon may be used as the starting gas at a pressure, e.g. of 25 torr. In series with the starter electrode 15 is a current limiting resistor 32 and on heating up a bimetallic switch 33 connects electrodes 13 and 15 together.
