Title: Piloting apparatus for a Missile Adapted to Damp Pitching of the Missile
IPC: G05D1/10
Filed: 1966-07-13
Abstract: 1,157,685. Controlling aircraft. CONTRAVES ITALIANA S.p.A. 13 July, 1966 [31 July, 1965], No. 31523/66. Heading B7G. [Also in Division F3] Piloting apparatus for a missile adapted to damp pitching of the missile, comprises two accelerometers 7, 8 spaced along the fore-andaft axis of the missile to produce first and second signals which are representative of linear acceleration parallel to a first axis transverse to the fore-and-aft axis. An adder 11 and lowpass filter 12 produce a third signal which is a function of the angular acceleration of the missile resulting from pitching about a second axis perpendicular to both the fore-and-aft axis and the first axis and passing through the centre of mass of the missile. This is fed to an adder 10 which also receives through a filter 9 the first signal, representing the actual linear acceleration as measured by accelerometer 10. The output from adder 10 is combined with a control demand signal received on a line 1, and the combined signal goes through a filter 3, amplifier 4, and a control device 5 to an aerodynamic control surface 6. Thus, the actual linear acceleration is equated to the desired linear acceleration to provide a linear relationship between the control demand signal and the actual linear acceleration. The apparatus is particularly suitable for use on missiles having a system for controlling the angle of roll.

Abstract: 1,026,306. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 15, 1963 [Aug. 23, 1962], No. 32297/63. Heading H4K. In a switching network in which each stage comprises a number of switching blocks KVA, KVB ..., Fig. 1, each block of one stage being connected by a single trunk to each block of the next, an idle through-route between a subscriber's line and a transmission path is selected by the application of markings at both sides of the network to guide wires associated with the trunks. In Fig. 1A, which shows two stages only, each switching block includes a PNPN diode 23 associated with an electromechanical switch 21. A forward " offering " signal applied at 27 fans out through all the idle trunks, and a backward " catching " signal applied at 28 brings about the operation of one diode in each stage to select a single route, the first diode to fire preventing the firing of any other in that stage. In the block KVB1, Fig. 2, in the idle condition an offering signal on an incoming guide wire mw, for example, passes forward to all the outgoing guide wires m1 ... mu. If a catching signal is received on one of the guide wires k1 ... ku an AND gate A1 opens and allows the signal to pass to the preceding stage, and at the same time relay K energizes to control switching. A control circuit AGB ensures that only one block can retransmit the catching signal. The circuits of Fig. 2 are shown in greater detail in Fig. 3 (not shown). The same guide wires may be employed for the offering and catching signals, Fig. 4 (not shown).

Abstract: 1330363 Regulating I.C. engine fuel injection ROBERT BOSCH GmbH 9 July 1971 [11 July 1970 29 Oct 1970 26 Nov 1970] 32320/71 Heading F1B [Also in Division G1] In an I.C. engine fuel injection control system, a switching circuit TS is switched in synchronism with engine rotation to supply injection valve opening pulses during the discharge of an electrical storage device, which is charged prior to each discharge operation, an air quantity meter LM arranged in the intake manifold 25 being adapted to convert the average value, with respect to time, of the quantity of intake air into an electrical variable which is proportional to the quantity of air alloted per engine stroke and which is applied to the energy storage device to vary the opening pulse duration. As shown, Fig.1, the air quantity meter includes a pivotable baffle plate 30 arranged to vary a resistance R being arranged in the charging or discharging circuit of the storage device. As shown in Fig. 4, the switching device includes input and output transistors T1, T2 and a capacitor C forming the storage device, the capacitor being, in one form of the invention, charged with a charging current JA dependent upon the value of the variable resistance R (R1 in Fig.4) for a duration inversely proportional to engine speed (pulse LJ), and discharged with a constant discharge current JE, the discharge time determining the duration of the valve opening pulses. Alternatively, the capacitor may be charged with a constant current and discharged with a current proportional to the reciprocal value of the average value, with respect to time, of the quantity of intake air. In an alternative, the resistor R may be in the form of a potentiometer arranged with its tapping connected either to the base of charging transistor T3 or discharging transistor T4, Fig. 6 (not shown). Advantageously, the baffle plate 30 is spring biased and arranged to provide an aperture between itself and the intake wall whose crosssection increases exponentially as the baffle plate is opened. In this case, the resistor R is arranged to provide an exponential function, Figs. 7-10 (not shown). The baffle plate is preferably clamped by an attached vane arranged in damping fluid, the damping force being temperature-dependent and direction of movement-dependent, Figs. 11-14 (not shown). The baffle plate may be arranged to be moved out of the flow of intake air by an electro-magnet, when a switch is closed to energize the electromagnet, when the engine is at full load and above a preset speed, Fig. 15 (not shown). The baffle plate may also be arranged to operate a switch to disconnect the fuel pump from its energy supply when the baffle plate is between its idling and fully closed position, the switch being operatively arranged in circuit with the starter and ignition switches, Figs. 16-18 (not shown). A stop, whose position is temperaturedependent, is arranged to position the butterfly valve 28 in an idling position, Fig. 12 (not shown).

Abstract: 172,626. Siemens - Schuckertwerke Ges. Dec. 10, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Cut-out arrangements; switches, clockwork actuation.-Relates to clockwork-driven meansfor opening or closing a switch 18 if a condition, such as an overload, continues for a definite time. As shown in Fig. 1, the driven wheel 2 is normally spring-held out of engagement with the constantly rotating wheel 1, but is brought into engagement with it, if the overload or like indicator 12 becomes operative to close a circuit for the winding 13, which on energization closes circuit for the winding 6 which by attracting its coil 5 pulls the arm 3 over against the action of the spring 4. The wheel 2 therefore rotates counter-clockwise and brings the stop 15 round to complete circuit at 16, 17 unless primarily the indicator 12 has ceased to be operative. In a modification, Fig. 2, the wheels 1, 2 are normally in contact so that contact will be made at 16, 17 unless previously the indicator has become operative. This modification can be used to cut out a unit at a power station if the demand falls. below a certain level.
