A logarithmic amplifier in an ionization detector of a nuclear reactor comprises (Fig. 1) an ionization chamber 1 connected over cable 2 to the input 3 of an insulated gate field effect transistor input amplifier 4 feeding an operational amplifier 6 having a stabilized network 8 energizing a cas-code output amplifier 10 whose low impedance output is connected over cable 12 to a differentiator 14 operative to shut down a reactor when the differentiator output increases at an excessive rate in response to ionization chamber current. A feedback loop from amplifier 10 includes attenuator 16, a temperature drift compensating network 18 of silicon planar transistors Q3, Q4, and a logarithmic element 20 comprising series silicon planar transistors Q1, Q2 connected as emitter-base diodes to the input of stage 4.

The base of Q3 is earthed over temperature compensation resistor R1 correcting for varying temperature characteristics of Q1, Q2. A time constant condenser C1 shunts elements Q1, Q2 to smooth out minor fluctuations of the ionization current, and a further feedback path from the output of 10 to the input of 4 is provided over diode Dl and resistors R2, R3 to limit the maximum time constant of the feedback path to a predetermined value when the resistance of elements Q1, Q2 tends to infinity. The mode of temperature compensation is described in detail (Figs. 2a, 2b, 2c, not shown) and a more developed circuit is also described (Fig. 3, not shown).

Title: Improvements in or relating to an electrolytic shaping apparatus and method
IPC: B23H9/00
Filed: 1963-12-27
Abstract: <PICT:1058930/C6-C7/1> <PICT:1058930/C6-C7/2> Material is electrolytically removed from an elongate workpiece 54, Fig. 2, while moving the workpiece past the working faces of series of spaced apart electrodes 34 and while pumping liquid electrolyte to and through the workpiece-electrode gaps at super-atmospheric pressure. The electrolyte is supplied through passageways 64 and leaves through passageways 66 provided with check valves 68 which prevent electrolyte escaping until the electrolyte pressure in the apparatus has reached a predetermined value. Electric current is supplied to the workpiece by brushes 74 which are slidable in passageways 76, Fig. 5.  Each brush is retained in its passageway by a spring but can be pushed forward against the spring action by air supplied under pressure through a passageway 86 to contact the workpiece. The workpiece is fed at constant rate through the apparatus and, as shown in Fig.2, the working face of each electrode makes a slight angle towards the workpiece in the direction of movement and preferably this angle is in the range 45' to 2 1/2  DEG .  The spacing of the electrodes 34 from the surface 57 of the guide on which the workpiece 54 moves diminishes from the end at which the workpiece enters the apparatus, preferably so as to maintain a workgap between each electrode and the workpiece not greater than0.015 inch. Electrolyte may be pumped through the workgaps at a pressure in the range 40 to 350 p.s.i. and direct current in the range 100 to 8000 amps at a voltage in the range 4 to 25 may be used for erosion.

Abstract: 1525127 Automatic exchange system TELEFONAKTIEBOLAGET L M ERICSSON 15 Dec 1975 [20 Dec 1974] 51329/75 Heading H4K In a switching network in which each input is connected to an output means are provided for connecting a certain input to a certain output by rearrangement of the network. The network comprises three link connected stages, each having at least two modules and the means comprises control equipment and control devices belonging to the respective modules which connect module inputs and outputs, the desired connection being derived by means of successive permutations of the connections within individual modules until the desired connection is attained. Apparatus.-The switching network comprises three stages, IM, MM and UM interconnected by link LK 1 , LK 2 . IM comprises modules IM0-IM2 controlled by devices SI0-2, MM comprises modules MM0-MM4 controlled by devices SM0-4; UM comprises modules UM0-UM2 controlled by devices SU0-2. All devices receive operating instructions from a distribution unit FE which is controlled by control equipment SU, shown in more detail in Fig. 8. The control equipment determines the necessary re-routings from the information stored in a switch memory KM and from information received from other units, e.g. registers of the system. The information in memory KM corresponds to the overall permutations of connections at the input of the centre stage MM (Fig. 6, not shown). Operation.-To connect a network input e.g. 0 arriving on line I to a network output e.g. 9, arriving on line U, starting from the condition described by Figs. 3 and 6 (not shown) a connection instruction is received on line KO. Under the control of a sequence generator SG, transformed designations e.g. 00, 14 are read out of stores JA, UA into registers XR, YR; a search follows which determines the addresses of store KM in which the above designations are stored and the addresses e.g. 00, 02, transformed by memory AA are read out into registers PR, RR; at the same time the input presently connected to output 14 e.g. input 24 and the output presently connected to input 00 e.g. output 20 are read out from store KM into registers WR, ZR. By means of circuits JK3, JK4 and OG a search is made for the address which identifies the centre module which presently interconnects 00 to 02 and for the input of this module which is connected to the output module containing output 14. The address e.g. 02 is written in register QR and the output designations in KM are shifted so that 14 goes to address 0 and 20 to address 2. Having updated the memory KM the reroutings are ordered by the control SU through FE. After the reroutings have been ordered, they are directed by control SU and if they are not possible, a new permutation is devised, as above, using the address in register QR. General.-The switching modules may comprise relays and the network may be digital (PCM) in which the links are represented by time slots in TDM frames and the control equipment may be realized by a computer.

Thereby the parison can then be presented in known orientation to a mould. The conveyer comprises chains 3, 3a with pins 20 therebetween. On the ends of the pins 20 are parison receiving means 19 each comprising a support pin 23, a bed 22 and a sprocket 25. The receiving means 19 has a flat surface 29, Fig. 5, at one side thereof, and this flat surface 29 is brought into predetermined position against a plate 30. A parison 26 is then lowered onto the receiving means 19 and rotated until its non- circular inner surface can pass downwardly over a correspondingly shaped part of the outer portion of the means 19. As the conveyer moves through the furnace, the sprocket 25 engages a chain at the side of the conveyer and is thereby rotated, thus rotating the means 19 and the parison 26. After leaving the furnace, the rotating parison receiving means 19 is stopped in a predetermined orientation by means of a device of the same construction as that shown in Fig. 5. The parison can thus be removed in known orientation for presenting to the mould. The furnace comprises horizontal air inlet ducts (1), Figs. 1 and 2 (not shown), and vertical outlet ducts (2). The conveyer is continuous and takes a sinuous path through the furnace.
