Patent GB-973948-A (GB)
Title: Improvements in or relating to spray pipe arrangements
Inventor: REISS AUGUST
IPC: D21F1/32
Filed: 1963-06-11
Abstract: 973,948. Spray-producers. REISS ENGINEERING CO. Ltd. Dec. 23, 1963 [June 11, 1963], No. 23252/63. Heading B2F. A pipe 1 carrying nozzles 2 (as used, for example, in the paper-making industry for distributing "white" water and fibre, or other material likely to clog the pipe) may be cleaned when necessary by a brush 6 reciprocable therein. One end of the pipe is connected to a fresh water supply 4 and a drain pipe 5 through a three-way cock 3 whilst the other end connects through a Venturi 14 and a stop valve 15 to a "white" water supply 16. The brush is secured between two plungers 7, 71 and the pipe has an open discharge nozzle 12 adjacent the brush, when the latter is in its non- operative position next to the cock 3, to prevent a "dead pocket" arising between last nozzle 2 and the brush. In normal spraying operation the cock 3 closes the supply 4 and drain pipe 5 whilst the valve 15 is open. To clean the pipe the valve 15 is closed whilst the cock 3 is manipulated to allow fresh water from the supply 4 to drive the brush along the pipe. Subsequently, the cock is actuated to close the supply 4 and open the passage to the drain pipe 5 whilst the valve 15 is opened. The brush is thereupon returned to its non-operative position being driven thereto by "white" water from the supply 16, the accumulated fibre and/or clogging matter being expelled through the drain pipe 5. In a modified arrangement fresh water is used to drive the brush both ways provision being made for this by replacing the valve 15 with a further three-way cock. Specification 727,036 is referred to.

Abstract: 1286909 Telephone exchanges; time-divisionmultiplex switching COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT ALCATEL and SOC LANNIONNAISE D'ELECTRONIQUE 13 May 1970 [22 May 1969] 23275/70 Heading H4K A time-division-multiplex highway switching system comprises at least three stages of switches, the switches in each stage each connecting a number of incoming highways to a number of outgoing highways by means of a buffer storage system which stores the incoming channel intelligence until it can be forwarded over a selected outgoing channel. As seen in Fig. 4, where only one switch is shown in each of the stages CE, CI, and CS, a switch such as CE1 has 32 incoming highways LRE each highway having 32, 8-bit channels, buffer stores REE set up the incoming channel codes in a parallel array of 32, 8-bit words, the total such array for all incoming highways being set up on a common buffer store MTE. A control circuit MCE for the switch has 10-bit storage compartments for each of the outgoing channels on the intermediate highways LREI, these compartments being read out in the time slots of the outgoing channels and providing the address of the incoming channel intelligence stored in MTE and requiring forwarding over the outgoing channel. Each of the intermediate highways LREI gives access to one of the switches of the second stage and similar trunking is provided with the intermediate highways LRSI between the second and third stages. The manner in which intermediate highway channels are selected to provide a transfer from an incoming channel on a highway LRE to a channel on an outgoing highway LRS, is not disclosed. Separate go and return channels are set up to provide a fourwire speech path. The individual switches are non-blocking and the network may have an intermediate stage of a scale sufficient to make the network non-blocking, or of a scale that introduces blocking which can be removed by the rearrangement of existing connections. Three-stage networks of the kind disclosed may constitute the intermediate portion of a 5-stage network which may constitute the intermediate portion of a 7-stage network, and so on.

Title: Manufacture of compounds of the anthracene series
IPC: C07C13/58
Filed: 1928-08-20
Abstract: 295,943. I. G. Farbenindustrie Akt.- Ges. Aug. 18, 1927, [Convention date]. Samples furnished. Anthraquinone derivatives.-Nitro compounds are obtained by treating 1 : 2 : 3 : 4-tetrahydroanthraquinone, or its homologues or substitution products, with a nitrating agent. When a mixture of nitric and sulphuric acids is used, a nitro group enters the ar-nucleus, and no dehydroge.nation occurs. Sulphuric acid alone has been found to have a dehydrogenating action on tetrahydroanthraquinone, while bromine converts them into unstable derivatives containing bromine in the hydrogenated nucleus, which easily lose hydrogen bromide and pass into the corresponding anthraquinones. In examples (1) 1: 2: 3: 4-tetrahydrosnthraquinone is treated with a, mixture of sulphuric acid monohydrate and nitric acid and the product is extracted with alcohol; the e residue. recrystallized from glacial acetic acid, consists of ar-a-nitro-1 : 2 : 3 : 4-tetrahydroanthraquinone, while the alcoholic extract yields a small quantity of the ar-#-nitro derivative, which on reduction and acetylation yields an acetylamino compound identical with that obtained by hydrogenating #-acetylaminoanthraquinone. (2) 1 : 2 : 3 : 4 - tetrahydro - 7 - metbylanthraquinone (obtained by hydrogenating #-methylanthraquinone in alcoholic suspension, under pressure, in the presence of a nickel catalyst) is treated with a mixture of nitric and sulphuric acids; the product. is probably 1:2:3: 4-tetrahydro-8- nitro-7-methylanthraquinone, and (3) 1 : 2 : 3 : 4- tetrahydro-8-acetylaminoanthraquinone, obtained by reducing and acetylating the a-nitro derivative of example 1, is treated with a mixture of sulphuric acid monohydrate and nitric acid: the product is probably 1 : 2 : 3: 4-tetrahydro-8- acetylamino-5-niti'oan.thraquinone. The products ars intended for use as intermediates in the manufacture of dyes and pharmaceutical products.

Abstract: 673,618. Time switches. GRETENER, E. Sept. 29, 1950. [Oct. 3, 1949] No. 23934/50. Class 38 (v). A spring set 4 is actuated according to a prearranged programme by a device comprising a disc 1 carrying on its circumference a row of pegs having slotted heads, such as 31 ... 33, the pegs being rotatably adjustable to pre-set the position of the slots. The disc is rotatable step-by-step to bring each head beneath a part 12 of a spring 5 arranged to enter the slots so that the contacts open if a slot, e.g. 31, 33, is arranged parallel to the axis of the disc and remain closed if a slot, e.g. 32, is at rightangles thereto. In order to prevent interference between the part 12 and the disc during the intervals of movement, the spring 5 is lifted by a bell-crank lever 7 pivoted at 8 and having an end 11 engaging rises 35 of a cam disc 10. In a modification, Fig. 2a, the disc 1 carries two rows of pegs 20, each of which has a recessed square part 21 engaged by spring blades 23 to locate the slot in either of its positions and to prevent accidental removal of the pegs. The flange of the disc 1 may be skimmed off at 27 so as to ease the entry of the parts 12 into the slots, and the pegs are sunk below the surface of the disc. The slots have recesses 25, the bottom surfaces of which are painted so as to give an easy indication of the slot position.

Title: Apparatus for producing electrostatic latent images
IPC: G03G15/22
Filed: 1971-07-21
Abstract: 1311040 Electro-photographic copiers MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 April 1971 [13 March 1970] 24146/71 Heading G2H In an electro-photographic copier, photoconductive film is passed through a cutter which cuts it into lengths, and a predetermined number of image frames are successively exposed, developed and fixed on each length; the frames having unexposed margins by which the lengths are advanced through the copier and the margins being trimmed off after processing. Preferably the copier is for micro-filming and the processed lengths are dispensed from the copier in mounts. As shown, Fig.2, the process starts with the end of film 52 unwound from a roll 68 and positioned at a charging and exposing station 36. On depressing the start switch, a corona discharge device (55), Fig. 4 (not shown), is moved into position by a pivoted arm (57) to charge the film. During charging, a cutter blade 74 is actuated to sever off a length of film capable of receiving two image frames. After charging and cutting the film is imagewise exposed using lamps 47, 48, mirror 67, shutter 50 and lens 49; exposure time being controlled by a timer. A transport system 39 comprising rollers 54, 56, 58, 60 then engages just the margins of the first length and feeds it to position the exposed frame at a developing station 79 and the second, as yet unexposed frame, at station 36. At station 79 a developing chamber 230, Fig.6, is moved into abutment with the first frame, is filled with developing liquid from a supply 232 (which liquid contacts the image at an aperture in the side of the chamber) and is then drained and retracted. On pressing the start switch again, the second frame of the first length is charged and exposed and then transport system 39 starts to feed a second length which pushes the first length so that the first frame is moved to a fixing station 81 (comprising a movable chamber 240 and a fixing liquid supply 242 similar to the developing system) and the second frame to developing station 79. Fixing station 81 may be omitted if the developing liquid also fixes. A roller 100 on a pivoted arm then advances the first length whereby firstly the second frame is fixed and secondly the whole of the first length is passed between a cutting roller 336 and cutting discs 332 (and 334) Fig.13, (not shown), to trim off the margins. The trimmed portions are guided away to a basket (365) Fig. 3, (not shown). A holder 460 containing a stack of mounts 380 is raised to position a lower pocket 390, Fig. 23, of a mount in the film feed path. A reciprocating opener 394 (also depicted in Figs. 25, 26 not shown), opens the pocket and a pusher 418 Figs.14-20 (not shown) shoves the first length 65a into pocket 390. The start button is then pressed third and fourth times to expose two frames on the second length 65b, and the holder 406 is lowered to receive it in a pocket 392. Rollers (498, 499), Fig.25 (not shown) eject the mount 380. The mechanical and electrical system controlling the copier is described in detail.
