Abstract: 1,258,198. Cryptographic systems. E. E. CLIFT. 30 Jan., 1970, No. 4483/70. Heading H4P. A cryptographic system has a translation matrix in both encoder and decoder coupled to a ring counter for cycling through a selected pattern and advancing the matrix in response to successive application of input signals, and means for resetting the ring counter to a selected position in response to selected input signals to resynchronize the encoding and decoding apparatus. A means is provided to maintain synchronization between the encoder-transmitter unit and the or all decoder receiver units, in order that ciphers will be translated in the proper corelation notwithstanding the random change in the cipher pattern. The cipher change occurs after every character but this sequence may be reset at random intervals. At the transmitter each key of k1, k50 of a keyboard encoder KI e.g. an electric typewriter can provide a combination of signals to activate coils of reed relays R1-R4 through a slide switch arrangement P1. The encoding apparatus includes a known cipher translator matrix unit MX-I having at each cross point two coils one MW1 connected to a first reed relay contact and the other MW2 to a ring counter RCI the latter being stepped one position for each depression of a key through second reed relay contacts. The ring counter may also be reset at any time by key K50 through relay R1. The matrix controls through contacts e.g. MS1 a combination of resonant reed oscillators E1-E50 the outputs from which are transmitted by line or radio. At the receiver the process is reversed and the inputs are identified by reed frequency selection circuits (D1-D50), Fig. 4 (not shown), the outputs from which are coupled to a further slide switch and an amplifier to relays R2A etc. each of which energize a horizontal row of windings e.g. MW2A, the vertical sets of which are energized sequentially through a ring counter RCIA, the counter being stepped one at each character reception. The characters e.g. K1A on a printer are energized from the matrix which printer may be part of a teleprinter.  To prevent the possibility of unauthorized recognition of the cipher pattern the relay R is used at random to reset the ring counter which also ensures synchronization between transmitter and receiver this also being ensured by a latch circuit each time the system is shut down at the close of a transmission.  It is stated that an advantage of the invention is that no key or tape is required to obtain a deciphered print out.

Abstract: 1,264,266. Verifiers. DATA RESEARCH CORP., and COMPUTER UTILITIES CORP. 10 March, 1970 [22 July, 1969], No. 11464/70. Heading G4M. A card punching machine comprising a punch head 13 which may be controlled by a keyboard 14 or a read head 16 (if a previously punched card is to be duplicated) is modified to operate as a verifier by an adapter (Section B) which includes switching circuits for interrupting the paths between punch head 13, keyboard 14 and read head 16 and connecting them to first and second inputs of a comparator 55 which controls an error indicator, e.g. a lamp 22 and/or a keyboard lock: Verifying operation.-With switches 19, e.g. relay contacts, in the V position, an entry from keyboard 14 supplies character-representing signals on lines 25 to comparator 25 and energizes line 41 to drive shaft 30 so that sensing pins in head 16 read a card column and supply signals over lines 38 to the other comparator input. If the two sets of signals correspond, comparator 55 energizes drivers 52, 53 in coincidence with a strobe pulse, 40, 51, to unlock the keyboard 14 and allow the card to be fed to the next column. If the comparator inputs . do not correspond, drivers 52, 53 are not energized, latch 54 is set, error lamp 22 is lit, and counter 56 is advanced to 1. The operator presses error reset button 23 to reset latch 54 and energize driver 52 so that a second keyboard entry  attempt can be made. If three attempts are unsuccessful, counter 56 disables the error clear  circuit 57 and enables error skip circuit 58 so that no further attempts can be made at that column, which may be marked by the operator as incorrect. On pressing button 24, latch 54 is  reset, and drivers 52, 53 are energized to release the keyboard and advance the card to the next column.

Abstract: 1295444 Wrapping machines D DUNNING 7 Oct 1970 [7 July 1969] 23388/69 Heading B8C, In a wrapping machine, one end of a sealable web is drawn through a guide 58 folded into a tube thereby, and transversely sealed at a sealing and severing station, and an article is passed through the guide 58 and into the tube to draw a further length of web through the guide 58 and to position the article beyond the sealing and severing station, the tube then being nipped and the nipped tube transversely sealed and severed. In a first embodiment, Figs. 1a, 1b, the article is carried on a flexible shuttle 50 coated with P.T.F.E. and carried by a channel member 46 movably connected to a trolley 22. The channel member 46 is moved relative to the trolley 22, and the latter relative to the machine frame, by means of a reversible electric motor 40 which drives a sprocket 32 carried by the trolley 22 and engaging a chain 20 secured to the machine frame and a chain 44 secured to the channel member 46. The web is a polyethylene film which is drawn from a reel 68 braked by a canvas web 72. The shuttle is transversely flexed, prior to entering the guide 58, by a pair of rollers 68. The shuttle 50 is retracted after passing the resistance wire 82, the article being held from retraction by the weight of a vertically movable nipping roller 84. Once the shuttle 50 is clear of the roller 84 the latter drops further to actuate a resistance wire 82 which is operative to sever the film. The completed package drops down a shoot 88. In a second embodiment (Figs. 14 and 20) a shuttle 158 is slidably mounted on the machine frame and is connected to an endless belt 150 driven by a reversible motor 152. A crossmember 178 is adjustably secured to the shuttle 158 and acts as a stop for a control slide 180 having a back stop 184 urged against the crossmember 178 by a spring 182. When the shuttle 158 is extended to carry an article through a folding box 174, ball catches 192 engage in recesses 194 in the cross-member 178 so that the slide 180 is held during initial retraction of the shuttle 158. Thus the article is held by the slide until the slide 180 is abutted by stops 190 on the shuttle, these stops causing the cross-member 178 to be released so that the slide 180 is retracted by the spring 182. In this embodiment heat sealing is effected by a sealing gate 240 comprising heating element (270, Figs. 18, 19) received in a rebate in an upper gate member (246) reciprocable with respect to a lower gate member (242), the gates (242, 246) nipping the tube prior to sealing. The upper gate member (240) is linked to an arm 282 acted on by a roller 284 carried by the shuttle 158 so that forward movement of the shuttle causes the upper gate member to be raised.

Abstract: 1297819 Radio navigation BENDIX CORP 4 Dec 1970 [12 Dec 1969] 57607/70 Heading H4D A method and apparatus for aircraft guidance includes beacons located at each end of a runway centreline transmitting signals which are received by the aircraft which has means to produce pulse trains indicating the positions of the beacons, the said pulse trains being used to modify the deflection voltages of a C.R.T. to produce a perspective display of the runway centreline. Signals E 1 , E 2 , E 3 , which are those applied to the display in Specification 966,622, are processed in computer 14, Fig. 6, to provide the C.R.T. deflection voltages. Signal E 1  representing the declination of the two beacons is separated into its constituent pulse trains by bi-stable 77 and switch 75 driven by the brightup pulse E 3  from the receiver. The pulses in each train are passed to hold circuits 93, 94 via switch 76 which under the control of comparator 121 ensures that the output from difference amplifier 98 is always positive ensuring that the final display is shown right side up. The amplifier 98 output is multiplied by a voltage E 9 , Fig. 4, and added to one-half of itself to produce an increasing vertical deflection signal during time t 1  whose amplitude is proportional to the difference in declination between the two beacons. The signal E 2  representing the beacon azimuths are similarly treated and the output of difference amplifier 98A is multiplied by a voltage E 7  to produce an increasing or decreasing horizontal deflection voltage during t 1  whose value and polarity depends on the azimuthal separation of the two beacons. During this time the C.R.T. thus produces a perspective view of the runway centreline. During times t 2 , t 3  the deflection waveforms E 7 , E 8 , E 9  and the separation signals are combined to produce horizontal deflections representing the near and far limits of the runway. During a final period t 4  an artificial horizon is provided. Waveform generator (Fig. 5, not shown).- The deflection waveforms E 7 , E 8 , E 9 , bright-up pulse (E 16 ) and control signals (E 10 , E 18 ) are produced by generator (15) which includes a programmer (40) providing timing pulses to a counter (42) whose output is converted by D-A converters into increasing or decreasing voltages of various slopes. These voltages are combined with fixed D.C. bias voltages under the control of switches operated by the programmer to produce the waveforms shown in Fig. 4.

The blank is fed by driven rollers 23, 24 through the machine and the heads are rotated by electric motors 10, (13), Fig. 3 (not shown). The lower heads 7, 8 are tiltably mounted on half-shafts (17) to change the required curvature of the blank, and are mounted on a vertically movable block (12) raised by drivable screws 21. In an alternative embodiment, Fig. 5 (not shown), the rollers (9) are arranged at an angle other than 90 degrees to the radii of the heads so as to feed the blank and the feed rollers are thus not required. The rollers (9) contact the blank normal to its surface and are spaced from the blank over part of their path by a distance ("a"), Fig. 5 (not shown), until the blank is fully formed. In a final embodiment, Fig. 7, the upper rotary head is made up of two parts 28, 29 each with its own roller set. These parts are relatively movable and have their axes of rotation slightly displaced from each other but in the same plane as the other rotary heads. The part-spherical blank may be used for the leaves of spherical vessels used in the chemical and oil industries. The blank may be carbon or stainless steel.
