Title: Process and apparatus for dyeing sliver
Inventor: CHANDLER NORMAN H
IPC: D06P7/00
Filed: 1962-01-12
Abstract: <PICT:0934015/IV(a)/1> A method of dyeing a fibrous strand comprises feeding a strand of fibres by engaging it between moving converging smooth surfaces and applying resilient back pressure against the strand to retain it against the said surfaces as it is forced out between them, applying dye to the strand prior to contact with the surfaces or to at least one of said surfaces in an amount not greater than the amount that the strand is capable of absorbing as the dye is forced through the fibres by contact with the said surfaces, releasing the strand from said back pressure and treating the dye to fix the dye to the fibre.  The dye may be applied in a solid colour, or to form a continuous stripe, or several colours may be applied so that the strand is dyed with stripes of different colours.  Apparatus for performing the method is as shown and in operation a strand S is fed from a source through a condenser 21 into the nip N of rolls 15, 17 which are rotated to draw the strand through and force it into the crimp box 23 and past the crimp gate 25.  Dye is fed at a metered rate through pipes 41 and 43 so as to supply dye at a known and constant rate to the felt pads 31 and 33 and thence to the surfaces of rolls 15, 17.

Title: Method and apparatus for packing filled bags within bales
Inventor: WOLVEN HAROLD LAWRENCE
IPC: B65B63/02
Filed: 1954-01-15
Abstract: 773,979. Baling bags. ST. REGIS PAPER CO. Jan. 15, 1954, No. 1310/54. Class 94(1). A method for tightly packing a plurality of bags filled with pulverent substantially non- resilient material into a bale comprises assembling a group of such bags in juxtaposition such that the transverse cross-section of the group has a maximum dimension in a predetermined direction, compressing the group in the direction of the maximum dimension to reduce the transverse perimetrical girth of the group ; inserting the group into a bale having an internal girth substantially equal to the reduced girth of the group and thereafter increasing the girth of the group of bags within the bale thereby tightly to fill the bale. As shown the bags are fed in pairs, comprising a group, 34, 35, Fig. 12, by a slow-moving conveyer 29 to a high-speed conveyer 28 which separates a pair from the next successive pair and moves it forward to a bag-receiving station 20a the oncoming bags operate micro-switches 30, 37 and 38 in turn to stop first the slow conveyer 29 and then the fast conveyer 28 until delivery of the next pair of bags is required. The bags 34, 35 are then pushed sideways on to the bale loading station 20b by means of the press-plate 22 of a shuttle ram 23 actuated by a manual control 42. At the limit of their travel the bags are compressed between the press plate 22 and a stop plate 24 which plates may be tilted from the vertical as shown in Fig. 5. The bags thereby compressed are then packed into a bale 51 by means of a packing ram 25 actuated by movement of the shuttle ram 23 past a micro-switch 49. The packing ram 25 moves the bags 34, 35 in a direction parallel to their longitudinal axes through a throat member 52 comprising an upper and lower duck bill 53, 54, Fig. 9, over which the open mouth of the bag bale 51 is stretched. The upper duck bill 53 which is pivoted to the lower one 54 is unlatched therefrom and a bale clamp released by the packing ram plate 26 as it approaches the end of its stroke. The baled bags are then transported by a conveyer 57 under a compression roll 66 which tends to restore the bags within the bale to their transverse substantially rectangular formation. After this compression the bale is discharged e.g. onto a transverse conveyer which may transport it to a bale-closing station. Control valves 69, 69a engaged by the packing ram plate 26 at the extreme end of its stroke retract the shuttle and packing rams to their initial positions. An arm 22a on the shuttle ram engages on its return a micro-switch 22b which starts up the conveyers 28, 29 for the next cycle. Instead of sloping press-plates 23, 24, vertical plates may be utilized but preferably in conjunction with an overhead platen which reduces the swelling of the top bag surfaces when under compression by the ram 23.

Title: Attenuation equaliser
IPC: H04B3/14
Filed: 1971-01-12
Abstract: 1342604 Synthesizing equalizer networks KOKUSAI DENSHIN DENWA KK 12 Jan 1971 [14 Jan 1970] 1382/71 Heading H3U An equalizer is synthesized by plotting its desired characteristic I, Fig. 1A, against a logarithmic frequency scale divided into an arbitrary number of equal divisions by equispaced dividing lines and obtaining an approximate characteristic II by drawing a number of straight lines between points coincident with, or close to, the intersections of the characteristic I with the dividing lines. The area between the characteristic II and the abscissa is divided into triangles and quadrilaterals. Each triangle, e.g. triangle (1) having apexes OMT, is drawn such that the apexes OT are on dividing lines such as A, C which are equi-distant from the dividing line B on which apex M is located. Similarly, each quadrilateral, e.g. quadrilateral (2) having apexes MNJT, is drawn such that apexes NT are on a dividing line such as C which is equidistant from dividing lines B, D on which apexes MJ are located. Other triangles (3), (5-1), (5-2), have apexes TJQ, KSR, and PQR, respectively. Another quadrilateral (4) has apexes JSRP. Fig. 1B is now constructed by drawing a characteristic IIa similar to II of Fig. 1A and constructing isosceles triangles (1)a... (5)a. These triangles have areas similar to the areas of the corresponding triangles and quadrilaterals of Fig. 1A and the distances along corresponding ordinates are equal: thus IVa=IV. Each triangle (1)a ... (5)a is realized by a constant resistance circuit of second degree function of the type shown in Fig. 2 and having the characteristic shown in Fig. 3, the dotted line showing the corresponding isosceles triangle. Five such circuits are connected in cascade (Fig. 4, not shown) to construct the equalizer.

Filed: 1967-01-11
Abstract: 1,155,761. Multiplex pulse code signalling. NIPPON ELECTRIC CO. Ltd. 11 Jan., 1967 [11 Jan., 1966], No. 1522/67. Heading H4L. In a time division multiplex P.C.M. system including a relay station with branching facilities, the relay station comprises a buffer memory for temporarily storing input pulse signals, means for generating clock pulses in synchronism with the bits of the incoming signal, means for generating clock pulses at a predetermined outgoing bit frequency, means for comparing the phase of the input and output clock pulses and means for subtracting from or adding to redundant pulses in the input pulse train in response to the output of the phase comparator. As shown in Fig. 4, an incoming P.C.M. signal, which includes " stuffing " pulses, applied at terminal 11, is written in to a store 21 via wiper 22 and read out to terminal 12 via wiper 23. The wipers may be in the form of electronic switches. The clock frequency of the incoming signal is extracted at 51 and supplied via a gate 42 to control the write-in, the read-out being controlled by pulses from a local clock generator 53 supplied via gate 43. The two clock pulse trains are supplied to a phase comparator 41 which when the input pulse timing leads the output by a half bit, closes gate 42 so that the wiper 22 rests for the duration of one bit time slot and a pulse in the received train is removed. Similarly, if the input signal lags by a half bit the gate 43 is closed so that wiper 23 rests for one bit period so that at one digit position the read-out takes place twice and an additional bit is inserted. The timing of the bit subtraction or insertion is controlled by a frame synchronizing signal detector 52 which controls the cornparator 41. Specification 1,047,639 is referred to.

Abstract: 649,904. Secret transmission. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. Jan. 20, 1948, No. 1745. [Class 40 (iv)] Secrecy is obtained in a transmission system by varying cyclically, within predetermined limits, the output frequency of an oscillator connected to effect frequency inversion of a signal, and by transmitting a pilot signal in which the frequency is varied at the same periodicity as the deviation in the inverted signal, but in which the frequency-deviation is a sub-multiple of the variation of the modulating oscillations. The speech for transmission, after passing through a band-pass filter 4, 0.3-3.5 kc/s., modulates a current of frequency 68 kc/s. from which the lower side-band, 64.5- 67.7 kc/s., is selected by a filter 6 to modulate a current of frequency 64 kc/s., varying cyclically by Œ 100 cycles, in the modulator 7, so that an inverted signal 0.5-3.7 kc/s. varying similarly, is passed to line. The oscillators 1, 2 which provide the modulating frequencies through frequency multipliers 3, 8 provide the fluctuating pilot frequency 200 Œ 5 c/s. through the modulator 10 and filter 11. At the receiver the pilot and intelligence signals are separated by filters 12 and 13 and the former signal after frequency multiplication is modulated by the 68 kc/s. output from an oscillator 16 to produce a current of frequency 72 kc/s. Œ 100 c/s. for converting in the modulator 20 the selected output, 68.5-71.7 kc/s., varying as above from the modulator 18, to the original signal.

Title: Process for the manufacture of oxidation products of phenanthrene
Inventor: BROOKS JAMES DOUGLAS
IPC: C07C51/31
Filed: 1952-01-23
Abstract: In a process for the manufacture of oxidation products of phenanthrene, phenanthrene vapour and gaseous oxygen are passed in contact with a catalyst mixture of vanadium pentoxide and potassium sulphate in a ratio within the range of 1 : 2 to 1 : 4 parts by weight at a temperature within the range of 300 DEG  to 500 DEG  C. for a period of contact not less than 0.1 and not exceeding 10 seconds.  The catalyst may be carried on silica gel or kieselguhr and is preferably maintained in the fluidized state by the passage of the gaseous stream.  Such a catalyst may be obtained by stirring silica gel catalyst in a molten mixture of vanadium pentoxide and potassium sulphate.  The process yields the lactone of 2 - hydroxy - diphenyl - 21 - carboxylic acid, 1 : 2-naphthalic anhydride and fluorenone and possibly also phthalic and maleic anhydrides, in proportions depending on the ratio of oxygen to phenanthrene and on the reaction temperature.  The phenanthrene used may be pure or a concentrate obtained from creosote oil or petroleum residues.  In examples the reaction temperature is 375 DEG  C. and the catalyst, used in the form of a fluidized bed, comprises vanadium pentoxide and potassium sulphate in the ratio of 1 : 3.5 by weight.  From the product maleic, phthalic and 1 : 2-naphthalic anhydrides are extracted with sodium carbonate solution, the lactone of 2-hydroxydiphenyl - 21 - carboxylic acid with sodium hydroxide, and the fluorenone in the form of its 2 : 4-dinitrophenyl hydrazone. Traces of 9 : 10-phenanthraquinone are also formed.ALSO:A catalyst for use in the vapour-phase oxidation of phenanthrene (see Group IV(b)], comprises vanadium pentoxide and potassium sulphate in a ratio within 1:2 to 1:4 parts by weight, which may be supported on silica gel or kieselguhr.  It can be prepared by coating particles (preferably spherical) of silica gel by stirring in a molten mixture of vanadium pentoxide and potassium sulphate.
