Abstract: 1,265,586. Automatic exchange systems. SIEMENS A.G. 20 March, 1970 [21 March, 1969], No. 13454/70. Heading H4K. A programme controlled data processing/system in which an address section and an associated decoder of an output command register in a programme control have direct links with a processing unit governed by the programme control so that, in order to. ascertain the requirements for programme jump instructions the processor may employ the address section of the output command register. The system has a programme control PW with a command store BS addressed from- BA by way of a command counter BZ, operations and address output register OT, AT, issuing- corresponding commands x, y, by way of decoders OD and AD. The processor IW comprises buses B1, B2, coupling operand registers OR1, OR2, with special process units VG, the processor being served by intermediate registers R1 to R4. Register R2 allows working with other processors over paths B3, B4, while register R3 allows response to core sensed external events for the system to work in, real time as in a telephone switching system. Processed data can be sent out of the system by way of register R4. Programme jump commands are derived over a path l3 to the programme store and can originate by direct instruction of special units VG or by way of a decision made in jump switching network SN. Input to the network SN can be applied: from-programme instruction decoder outputs x, y, either direct or by way of buffer stores r when the timing-of a jump needs to be controlled. Such input can also come from special process units VG or from external sources W. Jump instructions can also find an origin in data appearing in the address section of programme words which instruct the special process units VG. Such address section data may arise as the result of modification produced bythe processor operand register OR1 using the access provided by path l22 to the address section register-AT or; over path l21 to the decoder AD, the processor may obtain' access to data at any given location. A signal path l1 from the address section AT to the processor allows for data checking. An index register can be employed in the production of processor control output under the direction of the processor in the establishment of jump. commands. The jump switching network SN is employed to examine a sufficiency of conditions necessary for a jump command and to determine the nature of the jump according to the conditions examined. The programme may be modified by processor intervention to inspect the register R2 to examine external conditions 'the data being passed to VG for evaluation. Further registers may be examined in progression until possibilities are exhausted or until data is found that constitutes reason for a jump command. Such situations may be embodied by processes of scanning for calling substations or search for free connection paths.

Abstract: 1312619 Gas turbine engines - air intakes DEFENCE SECRETARY OF STATE FOR 30 Sept 1970 [3 Oct 1969] 48809/69 Heading F1G The invention relates to an air intake for a gas turbine engine and is described with reference to the air intake of a gas turbine ducted fan engine comprising a fan 14 mounted in a pod 11 comprising inner and outer walls 12, 13. The air intake lip comprises a circumferential series of lip members 21 each of which has an outer surface 22 which in the inoperative position abuts against a corresponding surface 23 of the fixed pod 11. The lip member 21 is arranged to move automatically to an operative position shown in chain-dotted lines in the event that static pressure within the intake becomes less than ambient pressure. Each lip member carries a pair of struts 25 on which are mounted rollers 26 which engage tracks 27 in side plates 28; the lip member is resiliently held in the inoperative position by springs 31. In the event of the pressure difference occurring the lip member is moved automatically to the chain-dotted position in which the dimension B is greater than A. An auxiliary air intake 35 is formed as the member moves to the chain-dotted position. In Figs.4 and 5 the intake lip comprises a circumferential series of lip members which are flexible. A piston member 51, 52 is pivotally mounted at 50 and defines two chambers 43, 44, the chamber 43 communicating with pressure within the intake duct through openings 47 and chamber 44 communicating with ambient pressure through openings 46. The forward end of the piston member is connected to the flexible lip and the rearward end of the piston member is in sliding sealed engagement with curved wall 40 of the fixed pod. Thus in the event of pressure in chamber 43 falling below ambient pressure the piston member pivots about point 50 and causes the lip member to distort to the position shown in Fig. 5, in which dimension E is greater than that C shown in Fig. 4. A member 55 mounted on a pivoted strut 56 also moves to the position shown in Fig. 5.

Abstract: 1320492 Tool holding assembly G S HIGGS 6 July 1970 [25 April 1969] 21208/69 Heading B3T  A tool holding assembly comprises a body portion 1 which pivotally supports a tool carrier 20 on which is adjustably mounted a tool 44, the body 1 being formed with a recess 8 in the face against which the tool carrier is mounted, the carrier having a corresponding projection which engages in the recess. The recess is formed with staggered under cut sides 10, 11 against which corresponding portions of the tool carrier projection abut in one direction of pivoting of the tool carrier. The carrier is pivoted on a pin 38 which extends from the body 1 into a bore 25 in the carrier which is parallel to a bore 2 through the body portion 1. The carrier is further provided with an open slot 26 in which engages an eccentric stop member 28, the stop member 28 and the undercut sides 9, 10 of the recess 8 constituting first and second stop means respectively. A spring and plunger assembly 33, 34, 35 are provided in the body member 1 to bias the tool carrier and hence the cutting tool 44 relative to the holder into an inoperative cutting position and into engagement with the first stop means 26, 28. In operation, when the cutting tool engages a workpiece which is coaxial with the bore 2 the cutting forces produce a reaction which pivots the tool carrier to disengage the first stop means and engage the projections and undercut portions 9, 10 forming the second stop means. This condition continues until the machining operation is ended when cutting tool disengages from the workpiece and the spring pivots the tool carrier to disengage the portions 9, 10, and engage the stop means 28. This pivoting action facilitates traversing of the tool along the work and prevents scoring of the work during a return traverse.
