Abstract: 1497439 Diverting residual current ROBERT BOSCH GmbH 26 March 1975 [26 March 1974] 12548/75 Heading H3T An arrangement for diverting leakage current, e.g. of transistor 11 {away from the base-emitter of transistor 10} comprises a transistor 20 whose base is connected to a tapping of a voltage divider 31 connected across forward biased diode 24, the amount of current diverted being determined by the setting of tapping 30, being typically 10<SP>-2</SP>-10<SP>-4</SP> of the diode current, and having an exponential temperature dependence. A plurality of transistors (20a-20c) Fig. 3 (not shown) may have their bases connected to the tapping to divert distinct, but equal currents, or the divider may have a plurality (30a, 30b), Fig. 4 (not shown) of tappings connected to the base of a respective transistor to divert a plurality of unequal currents. The arrangement takes the form of a monolithic integrated circuit. A switching circuit comprises switching transistor 10, and trigger circuit 11, 13, the current diverted through the transistor 20 for the "off" state of the switch being the collector leakage current of transistor 11, and the collectorbase leakage current of transistor 10. In a known arrangement, Fig. 1 (not shown), the base/emitter junction of transistor (20) in series with resistor 21 are connected across the diode.

Title: Storage to determine a connecting path via a switching network in telecommunication,particularly telephone exchange systems
IPC: H04Q3/545
Filed: 1966-03-25
Abstract: 1,126,075. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 March, 1966 [31 March, 1965], No. 13278/66. Heading H4K. In a multistage switching network having an associated core memory for storing the free/busy states of each interstage link, the addresses, in the memory, of all links which have access to each other are mathematically related. Trunking and cross-points (Fig. 2).-The network is a degenerate one which connects 16 inlets to 4 outlets via four stages comprising respectively four, 4 x 3 ; three, 4 x 3 ; three, 3 x 2; and two, 3 x 2 reed relay matrices. Memory (Fig. 3).-This comprises five columns of cores of which the columns correspond respectively to network inlets, A-B stage links, BC links, CD links and network outlets, and each core in a column represents a single link, outlet or inlet. Each core has a unique address which is related to the addresses of those cores corresponding to accessible links by the relationship:- the symbols will be explained in the example below. Operation.-It is assumed that a calling inlet requires access to any one of the network's outlets. Route selection takes place by selecting, in turn, the first free AB link accessible from the inlet, the first free BC link accessible to the chosen AB link, and, the first free CD link accessible to the chosen BC link. It is not discussed what happens if a free link in one stage does not have access to a free link in the following stage. As an example of the use of the memory, the following will be assumed: outlet (or link) B<SP>1</SP>32 whose unique core address is 35 (Fig. 3) has so far been selected; B<SP>1</SP>32 is the second outlet (N=2) from a matrix of the B (or second) stage, which stage has a total of 9 (m x , x=i- 1) outlets; the A (or first) stage has a total of 12 outlets (m x , x= 1); the core address of the first AB link A<SP>1</SP>11 is 16 (=E); each matrix of the C (or third) stage (i= 3) has (a i = )2 outlets: consequently the address of the core of the first outlet from the C stage to which B<SP>1</SP>32 has access is given by i.e. link C<SP>1</SP>21. If this link is busy, i.e. if its core is in the " 1 " state, logic circuitry adds 1 to its address and then interrogates the core, i.e. core 40 corresponding to link C<SP>1</SP>22 at this address. The core address of the first possible D outlet, i.e. D<SP>1</SP>21. is then obtained in a similar manner. The " arithmetic " is performed by a so-called translator (Z, Fig. 1, not shown) which is linked to the memory and to a control circuit that is used for core interrogation and cross-point control. The translator may be of the wired logic or stored programme type.

A process for the manufacture of tubes of thermoplastic material having a non-uniform wall thickness comprises extruding the material through a nozzle containing a mandrel to form an outlet gap of non-uniform width and bringing the plastic material passing through or emerging from the nozzle in the region of a smaller width of tube wall to a higher temperature than that of another section of the tube wall so that a rectilinear tube is produced. Plastic material is fed to an extruder head 5, to which is secured a nozzle 6 containing an eccentric core 7, and discharges through an annular opening 8 in the form of tube 9, 10. The nozzle 6 consists of at least two ring segments 11, 12 connected together by thin webs 13 such that heat conduction between the two segments is maintained as low as possible, and are made from different thermally conductive materials, segment 12 which is provided with an electric heating element 14 having a higher thermal conductivity than segment 11. Alternatively the nozzle 6 may be formed from more than two segments, the segments being thermally insulated from each other. Alternatively radiant heaters may be used external to the extruded tube. In a further embodiment of the invention the nozzle 6 may be so formed that it has a variable height with respect to its base so that greater heat dissipation may be obtained over one area of the nozzle than in another.

A yarn severing arrangement for use with a yarn feeding device comprises a feeler adapted to contact the yarn downstream of the feeding device so that on breakage of the yarn downstream of the feeding device the feeler actuates, via an electric circuit, a cutter which severs the.yarn upstream of the feed device. As shown in an arrangement for the cold drawing of synthetic copolymer yarn, a feeler 6 or 6<SP>1</SP> is placed either between the sets of drafting rollers or after the drafting zone. On breakage of the yarn the feeler falls to close an electric circuit, which energizes an electromagnet to displace a pawl and so allow a cutter blade, shown at 4, to move forward under the influence of a spring and sever the yarn. The cutting edge of the blade is preferably inclined to its direction of motion.
