Title: Signal switching device
IPC: H03K17/00
Filed: 1970-11-19
Abstract: 1275892 Automatic exchange systems NIPPON ELECTRIC CO Ltd 19 Nov 1970 [24 Nov 1969] 55125/70 Heading H4K [Also in Division H1] A two stage switching network comprises a set of parallel link conductors that are crossed by a set of parallel input conductors and a set of parallel output conductors. The input conductor and link conductor sets are each divided into groups and crosspoints are provided such that one conductor in each input group is connectible to a same level link in each of the link groups with the input conductors of a group being connectible to respectively different ones of the link conductors in any group of link conductors. The output conductors are arranged similarly but the grouping of the link conductors in this case is not the same as for the case of the input conductors. In Fig. 4A, the nine (1) link conductors W0- W8 are arranged on the input side in three groups W0-W2; W3-W5; W6-W8 which are crossed by three groups X00-X20; X01-X21; X02-X22 of input conductors on the output side in three groups W0, W3, W6; W1, W4, W7; W2, W5, W8 which are crossed by three groups of output conductors Y00-Y20; Y01-Y21; Y02-Y22. The relationship r.s=t.u=I should hold for the grouping where r, s, t, u, respectively are the number of conductors in an input signal group, an input link group, an output link group, an output signal group and l is the total number of conductors in the link set. The control of such an arrangement is effected by a corresponding array of e.g. ferreeds i.e. differentially wound magnetically latching reed relays that are energizable by coincident currents in both windings and are releasable by current in either one only of the windings. In Fig. 4B selection of a pair of crosspoint relays e.g. x 00 , w 0 , y 00 w 0  is effected by closing the relevant individual input and output marking switches p 0 , s 0 ; selected link switch p 0 ; and the relevant group switches l 10 , l 20 . In an alternative (Fig. 5, not shown), where the switches are such that they are only released by currents on the horizontal link control conductors and not simply on either the vertical input or output control conductors, the individual input and output marking switches are dispensed with and complete control is vested in the input and output group switches and the link switches. It is pointed out that the arrangement corresponds to a normal full availability trunking scheme in a network consisting of two stages each of three 3 Î 3 switches (Figs. 3A and 3B, not shown). The present arrangement however is much more susceptible to mass manufacturing techniques since the usual complication of crossing interstage link wires is eliminated.

Title: A process for improving the adhesive properties of artificial leather
IPC: C09J5/02
Filed: 1968-11-21
Abstract: 1,253,677. Bonding artificial leather. GLANZSTOFF A.G. 21 Nov., 1968 [23 Jan., 1968], No. 55223/68. Heading B5N. [Also in Division Dl] The adhesive properties of artificial leather which comprises a non-woven fibre structure which has been bonded and then impregnated with an elastomeric polymer are improved by applying thereto an aqueous electrolyte solution so that the artificial leather assumes a pH value of from 2 up to 7. The artificial leather may be treated with aqueous solutions of salts having a pH value of 2-7 when measured on a 10% by weight solution, or with a weak, non- volatile, organic acids in 1-10% by weight aqueous solutions. Aqueous solutions of salts of chromium, aluminium, zinc, iron, calcium or ammonium, e.g. zinc chloride, chromium chloride, iron chloride, calcium chloride or ammonium chloride, of sodium chloride and ammonium chloride or of citric acid, may be used. The artificial leather may be of a bonded non-woven fibre structure impregnated with a polyurethane or polyacrylate, and the treatment with the electrolyte solution may be effected on the finished artificial leather or in the final stage of the manufacturing process. The treated artificial leather may be bonded with natural leather or other treated artificial leather using aqueous dispersions of natural rubber, polychloroprene or a polyurethane.

Title: Arithmetic system for use in electronic calculator
IPC: G06F7/38
Filed: 1971-11-29
Abstract: 1376145 Calculator OMRON TATEISI ELECTRONICS CO 29 Nov 1971 [30 Nov 1970] 55242/71 Heading G4A An arithmetic system includes a keyboard having keys representing the decimal digits, several arithmetic function operations, a clear key and a constant key, a first storage means 5 for storing data signals, a second storage means 8, a gating means G4 having inputs connected to the first storage means and the constant key and an output connected to the second storage means and adapted to transfer the content of the first storage means to the second storage means when the constant key is actuated, and an arithmetic unit for operating on the contents of the two storage means. The system, which is said to be applicable to desk top calculators, includes a keyboard 1 connected via a digit encoder 2, gate Gl and adder 4 to a shift register 5. The register 5 is connected inter alia to a digit tube display 7. In operation when a series of calculations involving a constant are to be performed the constant is initially calculated, e.. by keying 3, + ,2, + ,4,x, = to obtain the result 20 which is stored in register 5. The constant key K is then locked in the depressed condition and a signal is transmitted via differentiator 9 to enable gate G4 for one word period and transfer the constant (K) from register 5 to register 8. The contents of register 8 are continuously recirculated via gate G5. To perform the calculation a x K the constant K in register 8 is added a times into register 5 by adder 4. The result is then gated, via gate G2 into register 6, and is thereafter transferred via gate G8 to register 5 for display by the display 7. The arrangement also allows numbers to be raised to the power n where n is an integer. The number a is transferred to register 8 as above except that a remains in register 5 and then the key x is depressed n-1 times, each actuation causing the contents of register 5 (i.e. a) to be multiplied by the constant which in this case is the number a. Rooting is also possible using the ¸ key in place of the x key. It is stated that a self return constant key could be used in conjunction with a suitable storage stage. The clear signal is applied to gates G3 and G7 to inhibit recirculation of the registers 5 and 6 and thereby clear these registers.
