Title: Visual and magnetic recording system
IPC: G06K1/20
Filed: 1974-05-08
Abstract: 1464468 Visual and magnetic data recording system J R ANDREAGGI and R J GRAF 8 May 1974 20267/74 Heading G4M A visual and magnetic data recording system has a typewriter 26 producing visual characters on the front surface of a sheet and recording data representing the character on a magnetic backing to the sheet in a fixed positional relationship to the visual character. The typewriter keys are arranged to operate switches 35 coupled to a diode coding matrix which supplies signals on eight lines to a recording circuit. The signals have six bits defining the character, a bit indicating whether upper or lower ease is used and a parity bit. The magnetic character on the rear surface is situated vertically in line with and spaced above the corresponding visual character. The recording head (Fig. 6) carries eight equally spaced wires 53-1 to 53-8 used to record the eight bits of each character, the wires produce magnetic areas in the backing aligned according to the direction of current in the wires (Figs. 2, 3 not shown). The wires do not form a complete single turn on a mandrel 52, are coupled to separate pins 53-1A 53-1B to 53-8A, 53-8B on a connector 59 and carry a high current for a short time. The eight wires are spaced by turns 54 of a continuous wire forming an erase portion of the head and extending beyond the end wires 53-1, 53-8. Further turns of the erase wire A, C are used to erase preceding characters or an area to receive the next character. The head may be formed of interlocking strips which have a longer life than the wires (Figs. 8, 8A not shown). The head may be mounted on a perforated support connected to a vacuum pump so that the backing is pressed firmly against the head (Figs. 5, 7 not shown). A circuit feeding pulses successively decreasing in magnitude to the erase coils is described (Fig. 14, not shown), and a circuit controlling the recording of "1"s or "0"s in each bit position and the alteration of the parity bit to agree with the use of upper or lower case are described (Fig. 13, not shown). A reader for the recorded sheet has a drum 201 on which the sheet is mounted with each recorded line extending circumferentially around the drum and a read head 191 indexed from line to line. The sheet rests on a resilient surface on the drum and is held in place by clamping cams 209, 210. The drum carries a magnet 300 arranged to operate in succession switches 302, 303 as the drum rotates. The switches are situated to correspond to the start and the end of each recorded line on the sheet. The read head is indexed by a solenoid 232 operating a cam 231 and a toothed rack 229. The reader feeds an electric typewriter and uses counters shift registers and a comparator, (Fig. 18, not shown), to read the characters in succession, one per revolution of the drum.

Abstract: 464,853. Germinating seeds. BOUILLON, C. G. V. July 18, 1935, No. 20511. Void. Convention date, July 21, 1934. [Class 58] To cause seeds to germinate after being suitably soaked they are introduced in suc cessive layers at appropriate intervals of time into a vertica container 1 provided with an opening 2 in the side near the bottom adapted to be closed by a hinged door 3, and with a cover 11 at the top carrying a pipe 12 that can be connected to a conduit 14 delivering ai saturated with moisture. The container 1 is provided witl an air jacket 15, the cover also being air jacketed. A water sea is provided between the cove and the container. A brace member 20 holds the cover in position against the pressure of air pumped through the conduit. Inspection holes 22 covered by a glass plate, sample extracting devices and a temperature indicating device 23 with thermostat, thermometer and signal are fitted. A perforated sheet metal slide 6 moves in guides across the container above the opening 2 and an adjustable false bottom 9 is arranged below the opening. In operation, layers of seeds previously soaked are introduced on successive days into the column, the door 3 being left open and air forced through the seeds from the conduit 14, the current being controlled by a thermostat; when the germ of the bottom layer has developed sufficiently the cover is opened, the door 3 closed, and the slide 6 removed, thus permitting the seeds to fall on to the false bottom. The slide is then replaced and another layer of seeds supplied to the top of the column and the cover replaced. The door 3 is opened and the seeds between the false bottom and the perforated slide removed. Perforated plates may be interposed between successive layers of seeds. A rotary cylindrical extractor may be used for the removal of the germinated seeds. Soaking vats for the seeds may be arranged round the upper end of the container.

Title: Improvements in or relating to automatic or semi-automatic telephone or like exchange systems
IPC: H04Q3/62
Filed: 1935-07-19
Abstract: 460,032. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and HARDWICK, J. R. July 19, 1935, No. 20621. [Class 40 (iv)] Subscribers at an automatic P.B.X are allowed to set up some outgoing calls automatically but are prevented automatically by discriminating means from setting up other calls, such as trunk or toll calls, without the help of an operator. Such calls may therefore be debited against individual subscribers. The discriminator may be at the main exchange and may be common to junctions from more than one P.B.X but, as shown, it comprises an auxiliary switch PM associated with an outgoing junction at the P.B.X. The discriminator may transfer a barred call to an operator. When the circuit is seized, A and B pull up and the digits are repeated in succession to PM, as well as over the junction, and a test is made when C falls back after each digit to determine whether the digits so far received belong to a barred number or not. If they do not, OK operates and the remaining digits do not step PM. It is assumed that TOL and TRU (878 and 805) are barred, and in such a case, the operating winding of OK is short-circuited over pm1 at the end of each of the first two digits, and at the end of the last digit BD pulls up, opens the outgoing junction and sends back NU tone. Certain allowable numbers, e.g. 8735 ... would also cause the operation of BD, but this is prevented by S which operates after the second digit and opens the circuit which would otherwise short-circuit OK at the end of the third digit.

In the arrangement shown, the current-conducting clamp 19, consisting of three bronze segments bolted together, is attached to a ring 18 forming the cover of a cylinder 17 co-axial with the electrode. This cylinder slides over a steel ring 16 packed with insulating material and attached to the top of a water-jacket 14. Two insulating rings 15 secured within the water-jacket 14 guide the electrode. Two wings 20 on the ring 18 secured to the electrode hold nuts 21 engaging screws 22 driven through worm gear by a controlled electric motor 25. The above-described devices are carried by a structure consisting of four uprights connected by a framework and secured by straps to angle irons on the furnace and on a ring above the roof. A metal frame within the ring supports the holders. To allow the furnace roof to be taken off, this structure can be removed by unscrewing nuts at the lower ends of the uprights and sliding these out of the straps. The furnace is tilted on rockers by hydraulic rams, and has oppositelydisposed charging and discharge openings. It may be provided with three upper electrodes, for 3-phase currents, and with a neutral hearth connexion.

[Also in Divisions B4-B5] A double shell vessel of resinimpregnated filaments is made by a two-stage winding process, the first stage involving winding on to a collapsible mandrel and the second stage involving winding on to the shell formed in the first stage. The mandrel comprises stave - like members 11, Fig. 1, supported at one end by a hub 12 mounted on a rotary shaft 13 threaded at 14 for attachment to a winding machine. The members 11 are supported at their other ends by a ring 17 mounted on a fitting member 18 located by a centring ring 21 secured to the shaft 13 by a nut 22. A release agent, e.g. a winding of polypropylene strap or two polypropylene caps, may be applied to the surface of the mandrel. The first shell 24 is then wound on the mandrel. A retaining ring 25 is then fitted to the member 18 and is held by a cap 25 so as to clamp the edge 26 of the shell 24 between the flanges 27, 28 of the members 26, 18. The resin of the first shell is now cured by heat or by a chemical action. The ring 21 and nut 22 are removed to allow withdrawal of the shaft 13 and the hub 12 so that the staves 11 and the ring 17 can be withdrawn out of the hole 31, Fig. 3.
