Title: Method of loosening cellulose fibres
IPC: D21B1/30
Filed: 1975-09-22
Abstract: 1511310 Subjecting wet lignocellulosic material to microwave energy treatment MO OCH DOMSJO AB 22 Sept 1975 [27 Sept 1974] 38856/75 Headings D2A and D2W A method of loosening or separating cellulose fibres in water - containing lignocellulosic material comprises subjecting disintegrated water - containing lignocellulosic material to microwave energy of such intensity and under such conditions that the water present in the lignocellulosic material is vapourised so rapidly as to reduce the lignocellulosic material at least partly to pulp without shortening the fibres to any appreciable degree and without damaging the fibres in any other way. In an example, pine chips having a moisture content of 70% were treated in a wave guide with microwave radiation, the temperature of the chips at the beginning of the treatment being at 100C. The wave guide was connected to a microwave generator having a power output of 5MW at a frequency of 2450MHz. The treatment can be effected at a pressure above, at. or below atmospheric pressure. The lignocellulosic material may be in chip form, or it may be wood whose fibres have been partially loosened by means of a defibrating device, or by a chemical or physical treatment. The lignocellulosic material may be subjected to a preheating process.

Title: A method of producing carbon fibres
Inventor: WHITNEY IAN
IPC: D01F9/14
Filed: 1969-08-04
Abstract: 1286534 Carbon fibres ROLLS ROYCE Ltd 29 July 1970 [4 Aug 1969] 38869/69 Heading C1A [Also in Division D1] Carbon fibres are formed by pyrolysing a sheet of longitudinally aligned polyacrylonitrile fibres and subsequently dividing the sheet along the length of the fibres. The pyrolysis may be preceded by an oxidation step in which the fibres are heated in air to a temperature between 150 and 300 C. After pyrolysis the sheet of carbonized fibres may be impregnated with a resin, e.g. an epoxy novolac, which impregnation may be performed by transfer of resin from a resin coated release paper to the carbon fibres. The division of the sheet, which may be performed with a plurality of slitting wheels, preferably takes place after the resin impregnation, the release paper being divided along with the fibre sheet. If desired there may be two separate sets of slitting wheels to divide the sheet in successive stages. The slitting step may be performed as a continuous process with the carbonizing step or the carbon fibre sheet may be rolled up after pyrolysis and offered to a separate slitting machine. In this event as the pyrolysed sheets are wound they are preferably interleaved with a release paper.

Patent GB-389943-A (GB)
Abstract: 389,943. Electric signalling systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. Jan. 13, 1932, No. 1043. [Class 40 (i).] In a totalizator system the dividends to be paid are signalled to the several paying-out booths from the central office and are indicated there on lamp panels. To ensure uniform voltage at the panels of the different booths, resistances of different values are inserted in the branch circuits to the booths. The control panel at the central office, Fig. 1, comprises banks of keys allotted respectively to win and place competitor numbers and to tens and units of shillings. Each key may occupy either of two operative positions to shift one of two movable springs b, e, Fig. 3, co-operating with fixed springs a, c, d, f. From the key springs proceed common lines for the various indicators of which one is shown in Fig. 2 comprising groups of lamps corresponding in arrangement with the keys of the control panel. The lamps of each group or bank are connected in series with one another and with the common lines and a resistance DR chosen in accordance with the resistance of the leads to that particular indicator. The springs of each bank are connected up in series as shown and in the normal position extend positive potential through the movable springs to the lead '0 and therefore the lamps DO, do, &c. When a value key is operated one of its springs is moved to divert the potential to the corresponding line and so light the lamps connected with it. When the operator wishes to signal he closes a contact RI to energize at each booth a magnet B which then locks up at b<1> through an acknowledgment key AK. A warning is also given through a buzzer BB controlled by contact b<2>. The signals having been sent, each booth attendant acknowledges their receipt by operating key AK so as to release B and energize a magnet A at the central station. This magnet locks up at a<1> through a lamp BO and when all these lamps BO are illuminated the operator can operate a release key RL to bring down magnet A.

Abstract: 1326055 Modulating and multiplex systems, active filters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Aug 1970 [21 Aug 1969 26 June 1970] 39929/70 Headings H3R H3U and H4R A data transmission system comprises: a data source 1 connected to a shift register 4 having elements 5 ... 14 whose contents are shifted by means of a control generator 2, 3; an oscillator 15 connected to a shift register 17 having elements 18 ... 27 whose contents are shifted by means of a control generator 16; a matrix 28 connected to both sets of shift register elements, and having weighting devices, e.g. 151, connected to outputs from the nodes 30... etc.; and a combining circuit 29 to which the weighted outputs are connected. As shown in Fig. 1, oscillator 15 provides a carrier signal, which is also used, via a multiplier 16, to shift the data along register 17. The data input 1 is synchronized with a clock source 2, the output frequency of which is multiplied in multiplier 3 to provide the shift signal for register 4. Amplitude modulation can be produced with suitable values of the weighting coefficients, if the matrix incorporates AND gates at the nodes. Vestigial sideband transmission can be obtained by modifying the coefficients, and if a code conversion element (273, Fig. 5, not shown) is included single sideband results. In another arrangement for SSB, Fig. 19 (not shown) a third shift register (341) driven by a sub carrier source (339) has its outputs coupled to the matrix. Phase modulation may be produced by replacing the AND gates with EXCLUSIVE-OR gates and modifying the weighting coefficients, or alternatively, Fig. 6 (not shown), by connecting a further network of suitable weighting impedances (274... 284) between the outputs of the register 17 and the combining circuit 29. To obtain frequency modulation, Fig. 7 (not shown) the circuit of Fig. 1 is used with EXCLUSIVE-OR gates and with the information signal 1 and a subcarrier source (286) coupled to the register 4 via an OR gate 285. Alternatively the subcarrier source and OR- gate may be used in the arrangement of Fig. 6 (not shown) with AND gates at the nodes. If a single carrier source and associated shift register are coupled to two matrices, Fig. 9 (not shown), each fed with a separate data signal, then the weighting coefficients can be adjusted to give orthogonal modulation. The circuit may act as an N-path filter, Fig. 22, if the signal to be filtered f 1 is constituted by source 1, and the switching signal f 2 is constituted by the source 339. In this arrangement, each node has three inputs connected to it, one from register 4, and two from register 341. With suitable weighting coefficient and suitable spacings between the two connections from register 341 to each node, it is shown that the circuit is equivalent to an N-path filter of the form given in Fig. 21 (not shown). The system may also be connected to several outputs through different weighting circuits to provide a carrier raster, Fig. 23 (not shown).
