Title: Method of producing pseudo-random binary signal sequences
IPC: H04L9/26
Filed: 1975-10-30
Abstract: 1517170 Pseudo-random pulse sequence generators LICENTIA PATENT VERWALTUNGS GmbH 30 Oct 1975 [31 Oct 1974] 45003/75 Heading G4D The invention relates to a way of producing very long pseudo-random pulse sequences. As described a first generator S.F.G. provides a plurality of trains of binary digits to a collator Z1. The collator comprises (Fig. 6.1, not shown) a plurality of controlled switching circuits which select which of the input trains is applied to which of a plurality of output lines. A second generator S.R.G.1 comprises one or more shift registers S.R. with feedback from selected stages to the first to generate pseudo-random trains in the usual way. The outputs of the collator are applied to modify the trains in the or each shift register. The outputs of the shift registers may be applied to a further collator Z2 whose output similarly modifies the trains from further feedback shift registers S.R.5, 6 whose outputs are then combined to provide the final long sequence. Alternatively (Figs. 7.1, 7.2, not shown) the outputs of S.R.G.1 may be combined to provide the final sequence. The first generator S.F.G. may comprise a multistage counter (Fig. 2, not shown) which repeated counts clock pulses to a preselected number or it may be another feedback shift register. The shift registers S.R.1-S.R.6 may have modifying inputs applied to more than one stage (Fig. 4, not shown) or the group S.R.1- S.R. 4 may be replaced by a single register with inputs to several stages. Variables in all stages are controlled by two classes of signal s and p. The p signals are derived from a programme and are fixed for a run while the s signals are derived from elsewhere in the system and thus continually charge. The s signals are not all the same but are interchangeable. These signals may vary the count in generator S.F.G., the selections made by the collators Z1, Z2 and the effective length and feedback paths of the shift registers; they may also be added into the pulse sequence at any stage. The final sequence can be made even more random by connecting the collators Z1, Z2 through code converters (Fig. 6.2, not shown).

Abstract: 1,167,710. Knitting-machines. K. I. J. ROSEN. 25 Sept., 1968 [25 Sept., 1967], No. 45555/68. Heading D1C. Yarn 1 is fed to a knitting machine by a driver roller 5 about which the yarn is wrapped after having passed between spring- loaded tensioning discs 7 which brakes the yarn. The yarn is then guided through a guide 21 on the end of an arm 15 of a lever the other arm 13 of which is spring-loaded and has an end 17 engaging between the discs 7 such that in the event of excessive tension in the yarn the braking effect of the discs is reduced and the roller 5 delivers the yarn more readily. Consequently a rate of delivery is maintained in conformity with the tension in the yarn. Instead of the guide 15 a pair of rollers secured to the arm of the pivoted lever cooperating with a fixed roller and about which the yarn passes can be used.

Abstract: 1471544 Direct reduction of ores BRITISH STEEL CORP and UNIVERSITY OF STRATHCLYDE 24 Oct 1975 [25 Oct 1974] 46305/74 Heading C7D In a process for the direct reduction of metallic ores, the particulate ore is mixed with a nucleating agent and an agent to promote activity of the reducing agent. In the case of iron ore, both the nucleating agent and the activating agent are FeCl 3 , the iron ore being magnetite or hematite and the reducing agent powdered coal, coke or graphite. The reduction of Cu and Ni oxides is also referred to. Other examples of activating agents are the halides, nitrates, carbonates, oxides and organic compounds of Fe, Ni, Co, Na, and Li; alternative nucleating agents are Fe, Ni, Co, and Cu compounds, especially halides, e.g. CuCl 2  for Cu ores,  NiCl 3  for Ni ores. Hydrides or organic compounds may also be added to produce H 2 . In an example a mixture of particulate magnetite, FeCl 3  and H 2 O was thoroughly mixed with a mixture of particulate coal, FeCl 3  and H 2 O; the pellets produced were dried, purged with cold N2, heated slowly in heated N2 to 1050‹C in a retort, held for 30  minutes, cooled in a cold N 2  stream and discharged, giving a 98% metallization.

Abstract: A memorising liquid-crystal display element has a smectic liquid-crystal layer (5) of positive dielectric anisotropy which is embedded between cover plates (1, 2) provided with electrodes on their inner surfaces. A pseudohomogeneous alignment with a zero rotational angle is caused. A pleochroic dye is added to the smectic liquid crystal, in order to lend the display device a colour in its pseudohomogeneous alignment state. A homeotropic alignment is induced by the application of an electric field. The restoration of the other state (colour) is performed by heating into the nematic phase and by recooling into the smectic phase. The heating can be performed by laser beams. <IMAGE>

The key can be removed only when the bolt 2 is fully shot. A coin 18 inserted in a slot 11 is supported in the coin channels 10 and 17 by a stationary step 19. Rotation of the key rotates the plug 8 of a cylinder-type lock mechanism counterclockwise, together with an attached cam 7 that bears against an abutment 9 of the slide 3 to move the slides 3, 12 and so slide the bolt 2 home (see Fig. 5, not reproduced). Simultaneously the coin 18 drops from the step 19 to be supported by the housing 1, and the coin slot 11 is blocked by a pin 25. On reverse rotation of the key, the bolt 2 and slides 3, 12 are retracted by a spring 4, the slide 12 pushing the coin 18 into a channel 20 (see Fig. 6, not reproduced) leading to a coin box or back to the operator. If the key is turned without coin insertion, complete rotation of the cam 7 is prevented by co-operation between a pin 21 and the abutment 22 of the immobile slide 12. In a modification (Figs. 1-3, not shown), the step 19 is located immediately above the channel 20, to allow the coin 18 to pass to the channel 20 when the bolt 2 is shot home.
