Abstract: 486,082. Two-way transmission. SIEMENS & HALSKE AKT.-GES. Jan. 31, 1938, No. 3000. Convention date, Feb. 3, 1937. [Class 40 (iv)] In a multi-channel carrier system involving three or more stations and comprising four-wire lines with amplifiers, the lines of each station are interconnected at a central point through frequency-selective devices in order to allow two-way communication between each pair of stations on appropriate frequency bands. In Fig. 2a, the lines from three stations A, B, C are interconnected through suppressors Su, Sm, So suppressing the bands u, m, o each of which includes a third of the total number of channels. In this arrangement, all the channels are available in one direction between any pair of stations, but only those within a selected band are available in the other direction. In Fig. 2b, in which filters Fu, Fm, Fo, are employed, each pair of stations is allotted an appropriate band for transmission in both directions. In Fig. 4, the channels are divided into two bands h, l, and the interconnections are made through filters Fh, Fl. Channels l carry signals from A to B, B to C, and C to A, while channels h carry signals in the reverse directions. This arrangement may be extended to interconnect N stations by the use of N-1 frequency bands. The bands may if desired contain unequal numbers of channels.

Patent GB-588329-A (GB)
Title: Process for the manufacture of artificial filaments or yarns resembling wool
IPC: D02G1/02
Filed: 1945-02-09
Abstract: Artificial fibres or yarns of a wholly synthetic character such as those of superpolyamides, polyurethanes, polyvinyl chloride or interpolymers of vinyl chloride and vinyl acetate are given a crimped wool-like appearance by treating the yarns, before or after high twisting, with an organic swelling agent which temporarily converts the individual filaments into a highly plastic condition, the swelling agent being subsequently removed from the yarn in the highly-twisted condition after which the yarn is back-twisted to or beyond the zero point.  Suitable organic swelling agents which may be employed with an inert diluent are phenol, meta-cresol, xylenol, formic acid, crotylphenol, secondary amylphenol, o-allylphenol, glycerine monochlorhydrin and dichlorhydrin, ethylene bromhydrin and chlorhydrin, lactic acid, thioglycollic acid, 2 : 3-dibromopropanol, phenylethyl alcohol and hydrocarbons such as xylene.  The swelling agent is removed from the materials by vaporization or by washing it out.  Doubled staple fibre, yarns and twists of staple fibre and continuous filament yarns may also be treated according to the process.  If desired, the treated yarns may be finally cut into staple fibres. In the examples: (1) polyhexamethylene adipamide yarn is swollen with a mixture of ethylene chlorhydrin and water, given a high twist in the moist condition and wound on spools.  The swelling p  agent is removed by a water wash and the material dried, unwound and given a reverse twist; (2) polyamino caproic acid yarn is given a high twist and swollen in a solution of formic acid.  The swelling agent is then washed out with water and the yarn dried and given a reverse twist; (4) two polyvinyl chloride-polyvinyl acetate yarns are impregnated with xylene and twisted together. The swelling agent is vaporized by warm air and the doubled yarn given a reverse twist, reeled, treated in hanks in a solution of lauric acid sulphonate, rinsed and dried.  Specifications 442,073, [Group IX], and 514,821 are referred to.

Abstract: 725,429. Casting-machines. INJECTA AKT.-GES. Feb. 6, 1953 [Feb. 8, 1952], No. 3381/53. Class 83 (1). [Also in Group V] A die-casting machine comprises a movable carrier structure adapted to receive the movable cope or upper die section and the support therefor and on which are mounted carrier plates movable relatively to said structure for core drawing and ejection, one of said carrier plates constituting a machine ejector plate and the other constituting a machine core plate, these two plates being coupled to the usual die ejector plate and die core plate respectively and forming a permanent part of the machine. The lower diepart 10 is secured to a fixed part 9 of the machine, a gate 11 being provided for filling the die. Four guide columns 12 extend upwardly from the part 9 and slidably support a carrier structure 18 for the upper die parts 20, 19. The carrier structure is moved downwardly to close the die by a hydraulic piston and cylinder 16, 14 respectively. The usual die core plate and die ejector plate 37, 35 respectively are provided (cores and ejector pins not shown), but these are operated through rods 36, 31, from further plates 29, 30 forming a permanent part of the carrier structure. The latter plates are moved relatively to the carrier structure by hydraulic pistons 28, 25 respectively, each plate being provided with a pair of pistons arranged diagonally opposite to one another. The rods 31 connected to the upper plate 26 pass through holes in the lower plate 29. Both of these plates are guided for vertical movement on short columns 18c connecting the upper and lower parts of the carrier structure. Hydraulic control of the machine may be such that the ejector plate is first moved upwardly, then the core plate moved downwardly and finally the carrier structure brought down to close the die. Alternatively, these operations may take place simultaneously. The carrier structure and plates 26, 29 may also be controlled pneumatically or mechanically.

Title: Improvement in photographic halftone plate and process of producing same
IPC: G03F3/02
Filed: 1925-02-06
Abstract: 251,697. Bassist, E. Feb. 6, 1925. Drawings to Specification. Chromo-gelatine and like processes; plates and films; photo-mechanical printing-surfaces. - A photographic half-tone transparency for use in making lithographic printing plates is prepared by covering a transparent base as of gelatine, celluloid, paper or, preferably, glass, with an opaque metallic layer as of copper or zinc, sensitizing the surface of the layer, exposing it to light together with the object to be reproduced, fixing the exposed portions, removing the opaque layer under the unexposed portions as by etching, and finally correcting for the desired tone and colour values. The opaque layer may be glued to the base or electrochemically deposited thereon. In the process described the surface of the layer is cleaned and coated with a sensitive layer comprising of fish glue, chromic acid, ammonium bichromate and water. It may then be exposed face-to-face with a half-tone negative or positive, bathed in cold water and washed with a water spray to remove the unexposed portions of the layer, and then dried and allowed to harden. The image remaining is hardened by heating, as by burning in, to make the glue acid-resisting. Where an inflammable base is employed, a cold hardening may be substituted, e.g. by using a res:nous sensitive layer and immersing in alcohol. The plate is then etched through to the base at the unexposed portions, and may be further treated by successive etchings to correct for tone and colour values, satisfactory portions being covered over with an acid-resisting material, like asphaltum. The positive or negative plate obtained may be directly reproduced on a zinc or aluminium plate from which the final lithographic prints are made.

Abstract: 881,675. Automatically adjustable shaft couplings. DAIMLER-BENZ A.G. Feb. 1, 1960, No. 3497/60. Class 80 (2). A shaft coupling circumferentially adjusted according to speed and for use in the drive to an internal combustion engine injection pump, a camshaft or an ignition control shaft, comprises a rolling mass or masses between plane, inclined surfaces on interdigitating projections fast with the two coupled shafts and two spring means acting thereon, one spring means opposing the. action of centrifugal force on the mass &c. to adjust the coupling and the other assisting the action of the centrifugal force. In one form, interdigitating segments 14, 15 on hubs 11, 12 secured to the two shaft ends have relatively inclined plane faces 16, 17 between which a ball or roller 18 is located, springs 21 between the segments biasing the plane faces against the ball &c. to oppose its radially outward movement under the influence of centrifugal force when the coupling &c. rotates and a spring 23, the compression of which may be adjusted by turning a screw 24, acting against the brass of the springs 21. The sum of the opposed moments exerted by the springs 21, 23 on the coupled shafts as they turn relatively to each other increases in a linear manner from substantially zero with increasing angle of turn. A stop (not shown) limits the angle through which the shafts may turn with respect to each other. In a modification, Fig. 4 (not shown), two balls &c. and two adjustably compressed springs are provided, and in another modification, Fig. 5 (also not shown), the adjustably compressed spring is replaced by a compressed spring located directly between two balls &c. and passing diametrically through the coupling hubs. As a further modification, the springs 21 may be arranged radially in the coupling on the outside of the balls &c. 18.

Title: Improvements in apparatus for sorting recorded digital data
IPC: G06F7/24
Filed: 1959-02-02
Abstract: 958,831. Data sorting apparatus. G. DIRKS. May 2,1960 [Feb. 2, 1959], No. 3548/59. Heading G4M. Data items are sorted in a number of stages in the first of which-the items are examined in sets of n and each set is ordered in sequence in a store, and in a subsequent stage a multiple of n items (i.e. a number of groups from the store) is examined and ordered. Figs. 3 and 4 illustrate schematically a sorter in which, at each stage, data items are read from tapes 101-103 and written on to tapes 104-106, the output tapes from one stage being utilised as input tapes for the next. A magnetic drum 107 is used for intermediate storage of items and comprises tracks 109, 110 for storage of alternate incoming items, from which the items may be transferred to gates 164 either directly over line l or via further intermediate storage tracks m, n, q, r, u, v. The control of these paths is effected by flip-flops such as 124, 157, which route items from 101 (I) to m or n, items from 102 (II) to q or r; the flip-flops such as 124 are controlled by the output of comparator 146 via register 126 and lines o, s, and w which when an item is removed from a track such as m, control the entry of another item from the same input tape. The parts of the data items stored in tracks m, n &c. which are to be used for controlling the ordering are selected by timing counters 228, 228 receiving clock pulses and preset by registers 230, and passed through gates 224 and over lines z to the comparator 146, which selects the item having the lowest (say) control for readout via gates such as 162, 163 to one of the output tapes. The elements enclosed in the broken line A of Fig. 3 are shown schematically in more detail in Fig. 5 (not shown). Fig. 6 (not shown) illustrates a second embodiment in which items from a single input tape are transferred to a synchronised drum, and when five items have been so transferred the control members of these are compared and the items transferred in order to a second synchronised drum, while a new set of five items are being written on to a second track of the first drum. After all the items have been read and ordered into groups of five, a second stage is started when two such groups are ordered into a group of ten, and so on. Specifications 847,961 and 851,752 are referred to.
