Title: Improvements in the production of sulphur-containing dyestuffs
IPC: C09B7/00
Filed: 1956-06-27
Abstract: Dyes containing sulphur are made by reacting an alkyl aryl sulphide with a dyestuff containing a halogen-methyl group which dyestuff is derived from a polynuclear compound having at least one >C=O or <C=N- group.  The products are stated to be the alkylmercaptoarylmethyl derivatives of the said polynuclear compounds.  The reaction may be carried out in presence of a Friedel-Crafts catalyst, and the products may be converted to sulphonium compounds.  Alkyl aryl sulphides specified are methyl, ethyl, propyl, isopropyl, butyl, or isobutyl phenyl sulphides or the corresponding compounds derived from thiocresols, thiodiphenyls, or thionaphthols, or their substitution products provided they contain at least one hydrogen atom capable of replacement in a Friedel-Crafts reaction, e.g. 2-, 3-, or 4-chlorthiophenol.  Types of dyestuff specified are the phthalocyanines, benzporphines, indigo and thioindigo compounds, anthraquinones, benzanthrones, dibenzanthrones, isodibenzanthrones, pyranthrones, and similar polycyclic ketones or quinones and their arylamino compounds.  Friedel-Crafts catalysts specified are zinc, ferric, and aluminium chlorides and boron fluoride.  A solvent, including excess sulphide, may be used, and a neutral salt such as sodium chloride or sulphate may be present.  In examples: (1) tetrakis- (alone or mixed with pentakis) chlormethyl copper or cobalt (or alternatively nickel, iron, aluminium, or metal-free) phthalocyanine is heated with ethyl or methyl phenyl sulphide or with methyl o-tolyl sulphide in presence of zinc chloride, the products being converted to sulphonium compounds by reaction with dimethyl sulphate, diethyl sulphate, or toluene sulphonic acid methyl ester; (2) thioindigo containing chlormethyl groups is reacted with methyl phenyl sulphide, with or without zinc chloride, followed by reaction with dimethyl sulphate; (3) a mixture of bis- and trischlormethyl-pyranthrone is reacted with methyl phenyl sulphide in presence of zinc chloride.

Title: Apparatus for moving Steel Sections
Inventor: HOLMES GORDON DAVID
IPC: B65G25/00
Filed: 1967-01-27
Abstract: 1,196,962. Reciprocating conveyers. DAVY & UNITED ENG. CO. Ltd. 26 April, 1968 [27 Jan., 1967], No. 19915/68. Divided out of 1,196,961. Heading B8A. [Also in Division B3] Conveying apparatus, for moving sections from an inlet table to a cooling bed, includes several carriages 1 which are slidable on rails beneath the surface of the cooling bed, each carriage having a finger which is raised to pull a section across the bed but is retracted when the carriage is returned to its initial position. In one form, Fig. 1, the finger 11 normally extends upwardly, but is moved to a retracted position by a pin 14 when the carriage is moved to the left. The pin is carried on a draw bar 5 which passes through the carriage and serves to drive it. Movement of the bar in opposite directions causes either a fixed abutment 7 or an adjustable abutment 8 to engage the carriage and drive it. In a modified form, Fig. 4, the finger 20 is biased to an extended position by a counterweight 23 pivoted to a common shaft 21. A pin 27 on the draw bar 5, when moved to the left, contacts the counterweight, thereby allowing the finger to pivot under gravity to a retracted position. Damage to a slender section, by positive retraction of the finger, is thus avoided.

Title: Improvements in and relating to programme control systems
IPC: D06F34/06
Filed: 1964-05-13
Abstract: 1,071,552. Automatic washing machines. H. OBERGFELL [trading as KIENINGER & OBERGFELL]. May 13, 1964 [May 13, 1963; June 26, 1963], No. 19933/64. Heading D1A. [Also Division H2] Variation of the duration of a cycle or any portion thereof in a stepping programme controller, (for washing machines, for example) is obtained by providing intermittent stepping movement at the fastest desired rate and selectively interfering therewith in a rhythmic sequence so as to produce slower stepping rates. A main shaft 11 (carrying operational cams not shown) is stepped by a pawl 25 oscillated by eccentric 27 which is driven via gearing from a synchronous motor 1. A hollow shaft 12, loose on shaft 11, is driven steadily by gear 10 from gear 9 (shown merely diagrammatically) and carries with it a track 20 and cams 13, 14, NIl, and N12. Pawl 25 is oscillated once every 90 seconds, for example, but steps shaft 11 only when gap 21 in track 20 allow engagement with ratchet wheel 24. This normally permits pawl 25 to move, say, three teeth of the ratchet 24 which corresponds to a single step in the main programme sequence of shaft 11. A spring 31 tends to lift pawl 25 clear of ratchet 24 but a stronger spring 36 acting on a lever 34 causes a pin 39 to urge the pawl towards the ratchet 24 unless an electromagnet 41 is energised whereupon pawl 25 is rendered ineffective. Cams 13 and 14 are used merely for operations which continue without regard to the programme control, such as oscillation of a washing drum. Cams NI1 and NI2 regularly actuate contacts, not shown, at intervals of 120 seconds and 60 seconds, for example, respectively. By manual operation of switches (Fig. 1, not shown) pulses may be fed from one or other or both of these contacts to the electromagnet 41 and by interference with the 90 second period of pawl 25 cause it to be ineffective for one, two, or three out of each four reciprocations (Fig. 2, not shown). Cams Npl to Np4 are provided on shaft 11 such that by manual operation of switches in series with contacts (not shown) operated by these cams certain selected portions only of the main programme may be extended, using the circuit, for example, of Fig. 6 (not shown). Temperature or water-level responsive switches may be connected to the electromagnet 41 to inhibit the programme progression. A plurality of gaps 21 may be provided in track 20, some of which could be rendered ineffective by operation of the electromagnet as a function of cams NI1 and N12 instead of, or in addition to, the control of the number of teeth engaged by pawl 25. The gap 21 may be made longer so that pawl 25 can move the shaft 11 more than one programme step to enable one or more programme steps to be overrun. A knob 12a is provided on shaft 11 for advancing the programme manually.

Title: Method and apparatus for the electrical treatment of liquids
IPC: C02F1/461
Filed: 1949-07-29
Abstract: 696,060. Electrolytic treatment of liquids. FREEBORN, A. G. June 26, 1950 [July 29, 1949], No. 19978/49. Class 41. [Also in Groups VI and VIII] A method of pre-treating a liquid fed through conduiting to a consuming stage, consists in passing an electric current through the liquid across electrodes located in intimate physical relationship with the liquid, and maintaining the potential difference across the electrodes substantially constant irrespective of changes in the specific resistance of the liquid, by connecting the electrodes to a source of low E.M.F., i.e. a small fraction of one volt whilst shunting the source by a resistance which is relatively low when compared with the resistance through the liquid between the electrodes. The method may be applied to the treatment of hard water to prevent scale formation in boilers, pipes, &c., to the treatment of paper pulp liquid to give added strength to the resultant paper, to the treatment of vegetable extracts to improve their flavours 'and keeping qualities, and to stabilize or break down emulsions. As shown in Fig. 1, two hollow metal members 1, 2 each formed with a boss for connection to a pipe line, are provided with flanges 1a, 2a between which is gripped a perforated metal electrode 3. The electrode is insulated from the members 1, 2. The member 1 functioning as an electrode is connected by a terminal 11 to one pole of a source of very low E.M.F., the other pole being connected by a screw 8 to the electrode 3. A resistance 19 which is relatively low, e.g. 1 ohm or less, in relation to the resistance through the liquid between the electrodes 1, 3, is connected across the source of power. In a modification two electrodes similar to the electrode 3 are provided which are insulated from each other and are held spaced apart by means of a flanged metal member interposed between two members 1, 2. The perforated electrodes may be partly coated with an insulating medium such as vitreous enamel. In the construction shown in Fig. 4, the hollow members 1, 2 increase in crosssectional area from the remote ends 16 to the flanged adjacent ends 1a, 2a between which a perforated metal electrode 3 is clamped. Direct current, alternating current, normal or rectified, or pulsating direct current may be used in the method. Specification 487,595 is referred to.

Filed: 1943-12-02
Abstract: 582,428. Inserting tubular rivets. DOWDLE, D. R. Dec. 2, 1943, No. 20121. [Class 43] A riveting tool of the type in which tubular rivets are threaded on a central rod has jaws which are opened against spring pressure solely by the contact of the rivets in the forward movement of the rivet carrying rod, and a hand lever and a rack and pinion for operating a piston connected to the rod. As shown, the member 6 is slidably fitted within a tubular member 5 secured in casing 1. It is normally urged forward by a coiled spring 7 against which it can be retracted by means of the handle lever 9 connected to a spindle 10, provided with teeth 12 meshing with teeth 13 in the underside of the piston member 6. The latter has an axial hole 16 through which passes the central rivet-carrying rod 17. The rear end of this rod is clamped to the piston by means of a split collet 18 tightened on the rod by a clamping member 24. The forward end of the tube 5 carries a head-piece 28 into which a nose or chuck member 29 is screwed. Jaws 30, which are fitted into a slot in the nose, are opened by the contact of the rivets 31 'as the rod 17 is moved forward and close automatically behind the flange of the rivet under the pressure of springs 38 to form a rigid anvil surface 35 against which the foremost rivet is held while it is being expanded by the mandrel head 44 of the rod 17. A feeding spring 42 feeds' the rivets forwardly along the rod 17. This rod can be completely withdrawn through the jaws when the clamping member 24 is released. A curved or straight extension fitting, Fig. 8, may be provided for use in awkward positions. Each fitting has a screwthreaded end 48 which is screwed into the head 28 after the chuck member 29 has been removed, and chuck fittings similar to the members 29 at the other end.

Title: Metallo-sulpho-methyl-phenols
IPC: C07C309/42
Filed: 1947-07-28
Abstract: Metallo-sulpho-methyl phenols, obtained by reacting a phenol having at least one open or closed chain saturated hydrocarbon substituent, the total number of carbon atoms in the substituents being more than 5, preferably between 8 and 20, such as di-isobutyl phenol, diamyl phenol, pentadecyl phenol or particularly hydrogenated cardanol, with a water-soluble formaldehyde-metal sulphite condensation product, are added to hydrocarbon oils, particularly those with flash points above 250 DEG  C., and greases, to prevent sludging.  In examples: a motor lubricating oil is treated with (a) barium di-(sulpho-methyl hydrogenated cardanol); (b) lead di-(sulpho-methyl hydrogenated cardanol); (c) zinc di-(sulpho-methyl hydrogenated cardanol); (d) barium di-(sulphomethyl-diamyl phenol); (e) barium di-(sulphomethyl di-isobutyl phenol); and (f) barium di-(sulpho-methyl-menthyl phenol).  Greases may be prepared by dispersing a soap such as sodium stearate or aluminium stearate in a combination of a mineral oil and a metallosulpho-methyl phenol.ALSO:Metallo-sulpho-methylphenols are prepared by reacting a phenol having one or more hydrocarbon substituents, the total number of carbon atoms in all the substituents being greater than 5 (preferably between 8 and 20), said substituents being open or closed chain saturated hydrocarbon groups (e.g. di-isobutylphenol, diamylphenol, pentadecylphenol, menthyl phenol or hydrogenated cardanol), with a water-soluble formaldehyde-metal sulphite condensation product.  Conveniently the metal sulphite condensation product is prepared in situ by reaction of the phenol with formaldehyde and, for example, sodium sulphite or bisulphite, and, if desired, another metal such as calcium, lead, zinc, aluminium, nickel, cobalt, iron, potassium, lithium or barium may be substituted for the sodium, e.g. by acidifying the product and reacting it with a salt of the substituting metal radical. Suitable metal sulphites are sodium, potassium or lithium sulphites or bisulphites.  The products are used to retard sludging of oils.  In examples: (1) hydrogenated cardanol is heated with formaldehyde and sodium sulphite in water, the resulting sodium salt of sulpho methyl phenol HO.C6H3(C15H31)CH2SO3H is acidified to liberate the free acid and an aqueous solution of barium hydroxide is added to give the barium salt; (2) by using lead acetate in place of barium hydroxide in (1) the lead salt is obtained; (3) by using zinc acetate in place of barium hydroxide in (1) the zinc salt is obtained; (4) diamylphenol is used in place of hydrogenated cardanol in (1); (5) di-isobutyl phenol is used in place of hydrogenated cardanol in (1); and (6) menthyl phenol is used in place of hydrogenated cardanol in (1).

Abstract: 1,236,741. Photographic type-composing apparatus. INTERNATIONAL PHOTON CORP. 30 July, 1968 [2 May, 19671, No. 20318/67. Heading B6W. In a photographic type-composing machine where the master characters are carried through a projection zone on a continuously rotating matrix disc 2 there is provided a photo-cell 16. effective to generate an electrical pulse as each master character passes through the projection position (as determined by timing slits 6) and a multiple stage counter 32 which counts the pulses and provides a plurality of outputs to bi-stable switches whereby each of the switches is turned on when the counter registers a preselected count associated with that switch and turned off when the counter registers a different preselected count associated with that switch. Each switch is associated with a different cyclically recurring function of the composing machine (e.g. initiation of justification, lens shift, introduction of justifying leader, tabulation control, unit leading, displacement of a prism carriage, and register, tape or memory advance) such that each function is allotted a preselected period of operation synchronized with the rotation of the matrix disc. This arrangement replaces the "timing cams" associated with the matrix disc of a conventional machine. Disc 2 may he divided into four quadrants each quadrant bearing a different type style and having a special timing slit, e.g. 8. Fig. 1, identifying each successive quadrant such that by employing circuits 20 and 22 the counter 32 may be set through one of the gates 36. 38, 40 and 42 to count the timing slots associated with the quadrant hearing the type style in use. Circuit 46 counts the pulses and compares the count with the count required for a selected character and triggers the flash circuit 48.

Abstract: 218,865. Clayton, M. G. Aug. 11, 1923. Compulsory differential driving. - Hoisting apparatus movable along rails is provided with means for driving the inner and outer wheels at different speeds at curved portions of the track. The wheels 4, 5, driven from a motor 6. are normally connected by gearing and a clutch 23 so as to rotate together, but on approaching a curve, a guide rail 55 or the equivalent throws over a clutch lever 24, so that the wheel 4 is driven through change-speed gear 25 - - 28. On approaching the next straight portion of the track, the clutch lever is moved back to the normal position. A safety device for cutting off the current if the guide rail fails to throw over the clutch lever comprises a slider 34 connected with the clutch lever, having a projection 35 which is in the path of one of two switches 40, 41 according to the position of the clutch lever. The switch arms 40, 41 are pivoted so as to move freely in one direction and to operate the switches when moved in the reverse direction. The arrangement is such that when the crane &c. is moving from a straight to a curved portion of the track, if the clutch lever is in the correct position, the member 35 engages the switch arm 41 without operating the switch, but if the lever is in the wrong position, the member 35 engages the arm 40 and cuts off the current. With the crane &c. travelling in the opposite direction, the correct position of the clutch lever is such that the member 35 again provides the safety control. The switches may be mounted on the slider 34 upon the travelling structure and co-operate with strikers adjacent to the track at 36, 37.
