Title: Method of producing a sheet bearing raised braille characters, and sheets produced thereby
IPC: G09B21/02
Filed: 1960-11-04
Abstract: 1,014,921. Communicating with the blind. F. BRAUN. Feb. 2, 1962 [Nov. 4, 1960], No. 38073/60. Heading G5G. [Also in Division B6] Braille characters are printed by using a type-casting machine to produce type slugs bearing the braille characters, setting the type slugs in a forme by locking them in a chase, printing from the forme on to a sheet using an ink, dusting the printed sheet with resinous powder which adheres to the ink, and heating the resin/ink mixture to produce the raised characters. A standard type casting machine may be used to produce the type-set braille, said machine using a perforated paper ribbon feed or a keyboard. The raised braille characters produced by the lead type are made up of solid dots.

Abstract: 1510806 Trunking in automatic exchanges INTERNATIONAL STANDARD ELECTRIC CORP 18 Sept 1975 [26 Sept 1974] 38362/75 Heading H4K In a switching network including a plurality of line selection units LSU and of group selection units GSU, each unit being provided with a number of input or output connectors 0-15 each having a plurality of wires, some connectors are joined directly by multiple wire link cables while others are joined via an interconnection device B1. The internal wiring of B1-Fig. 4-is arranged so as to afford the most even distribution of LSU outputs over GSU inputs. Both LSU's and GSU's are multistage networks, Fig. 1 (not shown), the inputs to the LSU's being from line circuits while the outputs from the GSU's are to junctors. In the example of Fig. 3, in which each input or output connector and link cable contains eight wires, adoption of the inter-unit trunking shown in solid lines results in an "even" interconnection of the first fifteen (0-14) inputs and outputs. Within the interconnection device B I the wiring takes the form shown in Fig. 4, this providing the most "even" distribution. In this case, device B I has four input and four output connectors, one of each being interconnected. The specification shows mathematically how the most "even" trunking and wiring distribution may be arrived at for differing numbers of the units LSU/GSU. A memory map may be used to record the busy/free state of paths through the network.

[Class 40 (iv).] In a telegraph and telephone transmission system wherein the direction of telegraph transmission is under the control of speech, means are provided to prevent operation of the telegraph transmitter until its circuit is in condition for transmission. The Figure shows the terminal equipment at one end of a cable c, the branches L<1>, L<2>, TL<1>, TL<2> being respectively the telephone and telegraph transmitting and receiving branches. The telephone and telegraph signals are separated by filters Fl, F2. When speech arrives on line L<1>, the output of the amplifier is divided between the delay network D and detector AD<2> which operates relays S<1>, S<2>, S<3>. Relays S<1>, S2 connect the telephone and telegraph transmission lines to the cable c and relay S<3> which is slow to operate effects a delay in the operation of the telegraph transmitter TT until after the line TL<1> is connected to the cable C in order to prevent loss of signal during the switching period. In order to prevent both terminal stations being operated simultaneously to transmitting positions, a pulse of tone or other current may be transmitted during the delay period of speech to disable the equipment at the distant end.
