Abstract: 1,238,113. Code converters. STANDARD TELEPHONES & CABLES Ltd. 7 March, 1969, No. 12223/69. Headings G4H and G4R. A code converter for changing variable length input code groups into parallel binary codes on a fixed number of leads comprises a shift register adapted to receive the code elements of the input group and to be shifted by each code element except a group termination indicator, which causes the register to read out a parallel binary output, a binary "1" being entered into the first stage of the shift register while the remaining stages are reset. As described the input is in speech form, the code elements being long or short as in Morse code and represented by the sounds "dar" and "di". The end of a code group is indicated by a pause, i.e. silence, exceeding a given minimum length. The discriminator 1 distinguishes long and short bursts of sound and long and short intervals of silence. The input signal is applied to an envelope detector 11, if desired via an automatic gain control 18 and band-pass filter 17. Threshold circuit 12 has an output representing "sound" which is passed to an integrating monostable 13, and inverter 14, the output of which represents silence. The output of monostable 13 is always "0" if the input is "0" and only rises to "1" if a "1" input has been continuously present for a specified time. This represents a long burst of sound and is applied to terminal B. The same signal is inverted at 16 and applied to terminal A. The silence signal from inverter 14 passes direct to terminal C and to an integrating monostable 15 connected to terminal D. The output C signifies a short interval of silence, and that at D a long interval of silence, i.e. the indication of the end of the code group. The signals A and B are applied as the 0 and 1 inputs of the first stage of the shift register 3. The shift line 31 is connected to terminal C representing the short intervals between code elements. The long interval signal D is applied to another integrating monostable 7, the output of which, inverted at 8, is used to reset all stages except the first to "0", the first being set to "1". The mark and space outputs from the six stages are applied to the column wires of a matrix decoder 5. The row wires are connected in groups of seven to gates 50. The seventh wire is the read-out line 51. The read-out signal is derived from a gate 50 connected to the row wires 56 corresponding to a special code group the purpose of which is to switch the machine on. The output of gate 50 sets a flip-flop 58 and the set output is gated at 57 with the termination signal from monostable 7. The row wires 59 and gate 50 recognize another special group the purpose of which is to switch the flip-flop 58 back to the inactive state thereby putting the converter out of action. The outputs, of which there may be about 60, may control a typewriter. Instead of using a voiced input a keyboard may be used, either producing binary outputs or signals from which a discriminator may produce a binary output. Specification 172,946 is referred to.

Abstract: 1,239,109. Read only memory. NORTH AMERICAN ROCKWELL CORP. 24 Nov., 1969 [6 Jan., 1969], No. 57447/69. Heading G4A. The invention relates to a read-only memory. As described an 11-bit memory address word a 1 -a 11  is divided into two portions, bits a 1 , a 2  and a 3 -a 11 , the most significant 9 bits a 3 -a 11  being applied in true and inverted form to an address tree 2 to couple an output terminal 10 to one of the 512 terminals 1-512. The least significant two bits a 1 , a 2  are applied in true and inverted form to a logic section having 16 lines corresponding to the 16 logic operations of the two bits shown to the right in the Figure. The terminals 1-512 are coupled to selected ones of the 16 logic lines and the sixteen logic lines are coupled to an input terminal 13 such that for any selected path or address in the tree 2 is coupled to the input terminal by the 16 logic lines so that a pulse passes to the output terminal depending on the value of bits a 1 , a 2  and whether the appropriate logic line is rendered conductive. Thus each address in tree 2 can read 4 values from the memory, the values depending on the logic line coupled to the terminal 1-512, e.g. 512 is coupled to logic line a 1 , a 2  only so will read "1" for a 1 = 1, a 2 = 1 and "0" for the other three values of a 1 , a 2 . The circles represent MOS devices rendered conductive by a "1" applied to the control electrode. The memory requires less lines than a conventional tree for an 11-bit address, which would have 2048 lines.

An anti-skid regulating device, for a compressed air braking system, comprises a duct connection between a brake cylinder 3 and a source of compressed air 8 via lines 2, 4, 7, pressure release means, constituted by an outlet valve 16, a stepped piston 17, an auxiliary piston 18 and air-venting valve 19, operable in dependence upon a skid senser 14 to close the said connection and bring about a rapid lowering of pressure in the cylinder 3 when a skid is sensed upon attainment of a first braking pressure, and to re-open the connection when the skid ceases so as to allow a second braking pressure to be attained rapidly in the brake cylinder, the device maintaining the second pressure throughout an intermediate braking period and allowing an additional rise of pressure at the end of that period, the second braking pressure being less than the first and being determined by movement of the stepped piston 17. The duration of the intermediate braking period is determined by passage of air through throttling means comprising a nozzle 50.

Particularly suitable as A) is N,N'-bisacryloyl methylene diamine, obtained by condensation of 2 mols of acrylamide with 1 mol of formaldehyde. The reaction of A) with the cellulose fibre and with B) is accelerated catalytically by alkaline substances, e.g. alkali hydroxide and quarternary ammonium hydroxides. The treatment solutions should have a pH >11. The finish treatment is either done in a single bath containing A) and B) or in separate baths. Alternatively the textiles are pretreated with an aqueous or alcoholic solution containing only the alkaline catalyst instead of after the treatment with A) and B). Suitable solvents are aliphatic alcohols with 1-4 C atoms and/or water. Not so readily soluble compounds may also be dispersed with the help of emulsifiers. The treatment of the textile is carried out by padding or spraying at room temperature for 5-60 minutes with a liquid containing 5-100 g/l of A) and B). Then the textile is centrifuged or squeezed to give a residual liquid content of 100-400% by wt. and pre-dried at 100‹C. Subsequently a heat treatment of 1-60 mins. is carried out at >100‹C, preferably 120-160‹C by which A) and B) are fixed washproof on the textile material.

Each photocell is connected to a respective relay R1-R4, which controls respective contacts 112; 114A 114B; 116A, 116B; 118A, 118B. When "standard" bricks are being monitored a switch 120 is operated to short circuit the contacts 112 and a brick of correct size will not block all of the photo-cells 74, 76, 78 so that at least one of the sets of contacts remains open. If the brick is over size, all the photo-cells are blocked thus closing the contacts 114A, 116A, 118A and enabling a solenoid valve S to be operated after a delay provided by a timer T. The solenoid valve S energizes a control valve for an air cylinder 62 which pivots the ejector 52 towards the brick thereby pushing the brick off the conveyer. For "utility" bricks, the switch 120 is moved to its other position and an oversize brick will block each of the four photo-cells thereby closing the contacts 112, 114A, 116A, 118A and causing operation of the ejector mechanism.
