Title: Apparatus for dyeing, bleaching and other liquid treatment of a material in granular or fibrous form or threads
IPC: D06B5/00
Filed: 1955-04-21
Abstract: <PICT:0806883/IV (c)/1> Apparatus for dyeing or bleaching comprises a container 1 for the material, an expansion vessel 3 in which the liquor is heated by steam coils to 110 DEG  C., and a vacuum and compressor pump 5 connected via a four-port valve 8 and conduits to the container and vessel.  In operation for dyeing, the container 1 is exhausted for the purpose of removing air from the material by opening a valve 7 and the four-port valve 8 so that communication is set up between conduits 6 and 9 and the vacuum pump 5, a valve 10 to atmosphere being also opened.  When the desired degree of vacuum is obtained the valve 10 is closed and a valve 19 opened so that the heated dye liquor may flow from vessel 3 into the container 1 until a float valve 21 is closed.  The valve 8 is now operated by an impulse transmitting device (not shown) to allow the high-pressure side of the air pump 5 to communicate alternately with the container 1 through valve 7 and conduit 6, and with the vessel 3 through valve 15 and conduit 14, thus pulsating the liquor which however always covers the material. The liquor can either flow through the valve 16 and the conduit 17 to the outside of the perforated material support 2, or may flow through conduit 18 and valve 19 to the interior of the support 2. The system may be subjected to a certain constant superatmospheric pressure during pulsation by opening a valve 12 in a pressure conduit 11, a valve 13 being provided between the high- and low-pressure sides of the pump 5 so that a suitable pressure difference may be maintained between the two sides, and if desired an amount of liquor may be passed through a non-return valve 22 and conduit 23 into the container without passing through the material. After 10-15 minutes pulsation the dyeing process is complete, the spent liquor may be drained from the system through valves 16, 24, and the liquor residual in the material may be removed by air blown therethrough via an opened valve 25, pump 5, valve 8, and conduit 6. The material may be rinsed by water introduced into the container through valve 26 and drained in a repetitive sequence, or the water may be allowed to flow through continuously.  To examine the material during the treatment the liquor is forced back into the vessel 3, valves 16, 19 then being closed and valve 24 opened so that the pressure drops to atmospheric and the temperature to 100 DEG  C.  The lid of the container 1 may then be raised.  The vessel 3 may however be cooled by passing cold water through the coils 4.  Normal bleaching may be carried out as above for dyeing, but a more rapid bleaching operation may be performed by replacing the pulsation step by air and steam blown through the material.  For this purpose steam is introduced through valve 27 and air through valve 25; the moisture content being high so as not to dry the material.  After heating, the valves 7, 24 and 27 are closed and the material allowed to remain in the container for 40-60 minutes.

Title: Improvements in and relating to the winding of lace making machine bobbins
Inventor: PEGG WILFRID JOSEPH RAYMOND
IPC: D04C3/14
Filed: 1955-05-22
Abstract: 799,738. Winding lace bobbins. PEGG & SONS (1954), Ltd., J. Aug. 22, 1956 [May 22, 1953], No. 11633/55. Class 74 (1). [Also in Group IX] In the winding of lace-making machine bobbins, thread, extending from a source of supply to a full bobbin, is entered into an empty bobbin by positioning the extending thread in a convergent guide, registering the empty bobbin with the thread by inserting the rim of the empty bobbin into the guide and passing the thread into the empty bobbin by relative movement between the guide and the empty bobbin. As shown, thread T from a source of supply passes round a tension-controlling roller 11 over a first guide pulley 4, and over a second guide pulley 5 having convergent sides and mounted at the end of a spring-biased lever. The thread is wound up on a bobbin B1 at the winding station WS. When this bobbin is full the tri-point carrier 1 is rotated through a Geneva cross mechanism such that an empty bobbin B2. swings into engagement with the convergent sides of the guide 5 and the thread passes into the bobbin prior to its taking up position at the winding station WS. The full bobbin passes to the position B and during this movement cutter mechanism 10 is operated to sever the thread. When the motion of the carrier 1 is completed and a new bobbin is being wound a transfer plate 9 is rotated to transfer the full bobbin from position B to a tri-radical receiving magazine 8 and to replace it with another empty bobbin from the feed magazine 7. The complete mechanism may be repeated several times in an upward direction the various parts being driven by gearing from vertical shafts and the whole arrangement duplicated on both sides of the machine. All the bobbin spindles are driven through gearing from a single motor and the Geneva cross mechanisms for rotating the various carriers in a step-wise manner are driven from a separate motor. A stop mechanism is provided which operates a magnetic clutch to stop the drive and is under the control of a revolution counter so that each time a bobbin is fully wound its rotation is automatically stopped.

Title: Control Mechanism for Industrial Vehicle
IPC: B66F9/20
Filed: 1968-03-11
Abstract: 1,187,554. Controlling vehicles. EATON YALE & TOWNE Inc. 11 March, 1968 [27 April, 1967], No. 11692/68. Heading B7H. [Also in Division F2] In an earth-working vehicle having a shovel or bucket operated by hydraulic rams controlled by a lever 11 and a transmission controlled hydraulically by a valve 16 yieldingly held in positions for forward travel, neutral and reverse travel by a spring-loaded detent 17, power means are provided for operating the valve in one direction, a manually operated device being mounted on the lever 11 for actuating the power means. The valve 16 may be manually controlled from a lever 9 located on the steering wheel, through links 12, 13, 15 and bell crank 14. In its extreme right-hand position, in which the valve 16 is set for reverse travel, the bell crank 14 contacts the rod 23 of a piston 19 acted upon on one side by a spring 20 and on the other by compressed air from a source 29 controlled by a valve 26 located in the lever 11. The valve 26 which is urged upwardly by a spring 32 and may be moved downwardly by a push button 25, has two positions. In the position shown the supply of compressed air is cut off and the cylinder 21 is opened to exhaust through a passage 31. When the valve 26 is moved downwardly, the passage 31 is closed and compressed air passes through a passage 33 to act on the piston 19 so as to move the transmission valve 16 from reverse to forward travel. The arrangement enables the operator to change the direction of travel at the same time as controlling the implement with the lever 11.

Title: Improvements in or relating to electrical signalling systems
IPC: H04Q1/36
Filed: 1942-08-20
Abstract: 559,539. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. Aug. 20, 1942, No. 11701. [Class 40 (iv)] An impulse repeater is provided with a timing device for determining the speed of the incoming impulses and for modifying the repeated impulses in such a way that the breakto-make ratio progressively approaches a standard value, e.g. 2:1, for successive impulses of a train, the first impulse being repeated with a fixed break period. As shown, the timing device comprises a condenser QX associated with a neon tube NTA for controlling the release of the repeating relay PU which operates at each impulse break. The condenser is charged upon seizure of the repeater to 100 volts, say, from a potentiometer arrangement comprising resistances YY, YZ and is further charged over resistance YX while PU is operative until the striking voltage of the tube NTA is reached, when relay E energizes and disconnects PU. The first repeated impulse thus has a fixed break period of 55 milliseconds, which is correct for an impulsing speed of 12 per second. The condenser QX then discharges partially over resistance YZ (since relay C is now up) so that when its charging circuit is again closed by PU it has an initial charge depending on the impulsing speed, and the next break period is brought nearer to the correct value. In practice, the break-to-make ratio for successive impulses oscillates on either side of and gradually approaches the standard value. The approach may be hastened by the provision of an auxiliary condenser QY, Figs. 2, 3, which is charged initially to the same voltage as QX, the two condensers sharing their charges on the relapse of PU and then discharging together. In Fig. 3, QY is provided with a charging circuit over resistance YV while PU is up. The timing device for determining the end of an impulse train consists of a condenser QW and neon tube NTB, as in Specification 549,047, but in this case the charging circuit is completed on the relapse of PU so that the tube strikes after the maximum make period and operates relay ER to disconnect C. Release by the calling party produces a timed operation of PU, and the subsequent operation of ER opens the locking circuit of relay B. Specification 551,187 also is referred to.

Title: Alkamine esters of 1-aralkyl-2,5-dimethylpyrrole-3,4-dicarboxylic acids
IPC: C07D207/34
Filed: 1944-06-22
Abstract: Pyrrole derivatives of the general formula <FORM:0577628/IV/1> wherein X represents an aralkyl radicle in which the aryl group is phenyl or an alkyl substituted phenyl group, and R1 and R2 represent dialkylaminoalkyl groups, are prepared by subjecting a corresponding dialkyl ester to alcoholysis with a dialkylamino alcohol in presence of less than an equimolecular proportion of an alkali metal alcoholate.  The products may be used as activators of rubber vulcanization accelerators, and in some cases as local an sthetics in the form of their salts with strong mineral acids, e.g. hydrochlorides, which are obtained by reaction with the anhydrous acid, preferably in solution in an organic solvent such as ether.  In the examples, the following compounds are made by heating the corresponding diethyl esters with excess of the appropriate diethylamino alcohols in which a small amount of sodium has been dissolved: di-(b -diethylaminoethyl) 1-benzyl-, -p-methylbenzyl- and - b  - phenylethyl - 2 : 5 - dimethyl - pyrrole - 3 : 4 - dicarboxylate and di - (g  - diethyl - aminopropyl) 1 - benzyl - 2 : 5 - dimethylpyrrole - 3 : 4-dicarboxylate.  Dialkyl esters of 1-aralkyl-2 : 5-dimethylpyrrole-3 : 4-dicarboxylic acids are obtainable by reacting a dialkyl (e.g. diethyl) ester of diacetosuccinic acid with an aralkylamine, e.g. benzylamine, p-methylbenzylamine or b -phenylethylamine.  The reaction may be effected in glacial acetic acid solution.

Abstract: 582,628. Rotary stud fastenings. THOMPSON PRODUCTS, Inc. July 22, 1943, No. 11948. Convention date, Aug. 29, 1942. [Class 44] In an aeroplane cowling or like fastener of the kind in which a stud rotatably mounted on a cowling or like plate A passes through an aperture in the support B to which the plate is to be secured and engages by partial rotation in an apertured socket member secured to the support, the stud has helical surfaces 22 terminating in a wedge-shaped nose 27, and the socket has a spring finger or fingers the end or ends of which snap into engagement with an abutment surface or surfaces on the stud to prevent its accidental disengagement as, for example, by vibration. As shown, cowling and support have countersunk apertures which nest together as in Fig. 3. The stud has a correspondingly shaped head 20 with screwdriver slot, a stem 21 and shoulders 23 which pass through and by partial rotation engage over the edges of, an elongated aperture 15 in the socket member, and a pair of opposed helical edges 22 alternating with a pair of opposed abutment surfaces 25 ending in the wedge nose 27. The stud is retained in plate A by a grommet D. The socket member shown is formed from the spring-metal blank, Fig. 7 the ends being bent downwards and inwards to provide feet secured to support B by rivets 13 passed through apertures 14, so that the main socket portion with its aperture 15 is spaced from the support, whilst the fingers 11 are bent upwards and inwards so that their inclined ends 16 almost meet centrally above aperture 15. In use the nose forces the ends 16 apart, rotation of the stud allowing the ends (which are slightly bent downwards as seen in Fig. 8) to snap into engagement with the abutment surfaces 25 to retain the stud in fastening position. Engagement of shoulders 23 bends the main socket portion towards the support so that the parts A, B are held tightly together under spring tension.

Title: An improved abrasive article and method of manufacturing such article
IPC: B24D18/00
Filed: 1931-04-24
Abstract: Abrasive material is bonded or attached to a backing by a composition which includes an isomer of rubber less unsaturated than normal rubber.  The isomer may be produced by heating rubber with organic sulphonic chlorides or acids, sulphuric acid, or with substances which yield sulphonic acid when heated, the degree of saturation depending on the amount of the reagent added, and the temperature.  7 1/2 parts of p-phenolsulphonic acid added to 100 parts of rubber and heated to 120-145 DEG  for 4-10 hours yields a balata-like product about 67 per cent unsaturated compared with normal rubber, while 15 parts of p-phenol sulphonic acid heated with 100 parts of rubber to 140 DEG  C. for 8 hours undergoes an exothermic reaction, the temperature rises to 250 DEG  C., and a brittle shellac-like mass results, of about 25 per cent unsaturation.  By controlling the degree of isomerization, by mixing different isomers, or by adding other materials such as natural or synthetic resins, rubber, abrasive articles of any degree of hardness and flexibility may be obtained. Numerous examples of compositions are given: the following are typical:-(a) 1000 parts of abrasive grain and 100 parts of powdered flint are mixed with 500 parts of a solution of 17 parts of rubber isomer, 5 parts of rubber, 6 parts of sulphur, and 72 parts of solvent, e.g. benzol.  After forming a blank, the solvent p  is removed and the article is compacted and vulcanized.  (b) In applying abrasive to a backing, e.g. steel, the steel is sand-blasted and coated with a solution of 21,6 parts rubber isomer, 40 per cent unsaturation, 2,7 parts rubber, 0,9 parts of sulphur, and 74,8 parts of solvent, e.g. benzol.  Abrasive is sifted on and most of the solvent is removed.  A coat of thinned solution is applied over the abrasive, and after evaporation of the solvent, vulcanization is effected by heating to 320 DEG  F. for 1 hour.  Other examples are given in which phenolaldehydes are employed, and in which a material such as balsa wood, leather, rubber, is added for polishing wheels. Other backings mentioned are sheet rubber, woven fabrics, felt, paper.
