Title: Production of active carbon carrying acid surface groups capable of cation exchange
Inventor: BRINKMANN GEORG
IPC: C01B31/16
Filed: 1954-12-22
Abstract: Cation exchange properties are induced in active carbon by treatment with an aqueous alkaline solution of an alkali metal hypochlorite. The hypochlorite solution is preferably formed in situ by the reaction of chlorine with an alkali metal hydroxide, e.g. sodium hydroxide.  The alkali metal hydroxide and chlorine may be introduced into a body of carbon from below and spent solution removed from above.  The treated carbon may be washed with water to remove alkali and then converted to the hydrogen form by treatment with acid, e.g. hydrochloric acid. Alternatively the treated carbon may be further treated with sodium hydroxide solution and then with water to produce the sodium salt form.  Specification 509,859 is referred to.

A circuit includes a plurality of field effect transistors T1, T2, T3, e.g. MOST 5 , arranged in a plurality of current paths and a control circuit TA,R connecting each of the current paths to a voltage source 22, in which the control circuit normally exhibits a high resistance to limit current flow from the voltage source and in response to a timing pulse 24 exhibits low resistance such that a high current can flow from the voltage source to the paths. The circuit shown is a NOR gate, the inputs being applied to the gates of field effect transistors T1, T2, T3 which transistors are normally fed through resistor R to reduce standby power consumption, but, when read out is required, are fed through field effect transistor TA, rendered conductive by a timing pulse at 24. Transistor TA then provides a low resistance path to rapidly charge the stray capacitances (represented by C) and hence provide a rapid response. The output signal at 20 is of either +V volts, through transistor TA, should there be no inputs at 11, 12, 13, or ground, should there be at least one input. A further transistor TB may be provided, being normally conductive to hold the output at ground but rendered non-conductive by a-timing pulse during read out.

Abstract: 971, 206. Error correction. J. E. MEGGITT. Nov. 11, 1960 [Nov. 13, 1959; Aug. 4, 1960],Nos. 38602/59 and 27013/60. Heading G4A. Check digits are developed from a feed-back shift register and an adder according to a code defined by where T is a k x k matrix defined by the characteristic equation T<SP>n</SP> = 1; x is an arbitrary k x 1 vector; and the a's are the digits of a block of n - k data digits and k check digits. A feed back shift register is one in which selected stages are connected back to the input through an adder. The result of shifting the register is equivalent to applying a transformation T to the contents. If T defines a code of the kind required-then so does T<SP>-1</SP> since only the suffices of the a's are changed in the first equation. In the binary case C o  is then 1. An encoder is shown in Fig. 1. The connections of the feed-back register are determined by the C's. If a C is 0 there is no connection. C o  is always 1. The n-k data bits are received on line 13. Switch S 2  is initially closed so that the bits pass through the mod 2 adder 12. Switch S 1  is connected to the snift register 11. The outputs of the register are combined in the adder 12 to give expression to the first equation, with T replaced by T<SP>-1</SP>, and when all the data bits have been received switch S 2  is opened and switch S 1  connected to line 13 for transmission of the block of k check bits. In decoding there is computed where the a<SP>1</SP> are the received digits. If z = 0 the message has been received correctly and if z is, non-zero it shows within predetermined limits the number and kind of errors. Fig. 2 shows a decoder. The received data is operated on by the register 16 and adder 17 is the same way as in the decoder. Circuit 18 is designed to emit 1 when the pattern in register 16 is of a particular form. The received message is delayed in shift register 19 while the calculation is proceeding. When z has been calculated the register 16 is recirculated. When a pattern associated with an error in a particular bit is detected the bit will be in adder 20. The 1 emitted by circuit 18 will complement the bit and correct the error. The theory is explained in the Specification and examples of particular decoders are given. Where all errors occurring in bursts of up to x bits are to be detected, the output of register 16 is split into two parts and summed mod 2. The first adder receives the outputs of stages k-1 to x 1  and the second adder the outputs of stages x-1 to 0. When the first adder contains zero and the second adder contains 1, an error is detected. An extension of the theory to fields of 4, 8 or 16 elements is briefly outlined.

Abstract: 1299182 Recording-apparatus ELECTROLOCATION Ltd 27 July 1970 [4 Aug 1969] 38867/69 Heading G1J Plotting-apparatus comprises a pen 23, a record sheet carrier 10, motors for causing relative movement between the pen 23 and the carrier 10 in correspondence with a traverse of a surveying instrument over the ground, a tape recorder 28 for producing an output signal by playing back a recording of a signal made during the traverse and a variable pulse generator 27  controlled by the output signal and arranged to supply pulses at a frequency dependent on the strength of the output signal to actuate the pen 23 and produce marks at a corresponding rate. The pen is moved into and out of contact with a record sheet on a rotating drum 10 by a solenoid 26 supplied by the pulse generator 27 to mark dots, the dot-density thus depending on the amplitude of the output signal which may represent soil conductivity. The pen is mounted on a carriage 17 driven an increment along rails 16 at the end of each revolution of the drum 10 when a cam 14 closes contact CB2 to operate a motor 20; the increment being determined by pre-setting a variable resistance 32 and the motor 20 driving a threaded rod 19 engaging threads in a semi-cyclindrical recess under a nylon block 18 in the base. It is assumed that while the ground was being traversed, records were being made on a tape in two tracks, one recording a constant signal beginning and ending with each traverse and the other recording a signal varying with variations of e.g. soil conductivity or electromagnetic reflection coefficient of material in the soil. With manual switches 50, 51, 52 closed, mains switch S is closed to start a drum motor 11 then cams 13, 14 thereon momentarily close contacts CB1, C B 2 to energize the motor of the tape recorder 28 whereupon the constant signal picked up from one track energizes a relay 31 to close a holding circuit until the signal stops at the end of a traverse. Meanwhile the variable signal picked up from the other track causes the generator 27 to produce pulses at a frequency corresponding to the amplitude of the signal to vary the intervals between dots. The drum motor speed is selected within the range of a quarter to ten r.p.m. and each traverse is recorded in less than a complete revolution. Alternatively the records could be made on a sheet carried by a stationary flat bed plate and the pen carriage could be mounted for movement in two directions, one movement continuous, but reversible at.intervals and the other movement step-wise.
