Patent GB-574072-A (GB)
Title: Textile conditioning agents
Filed: 1943-12-29
Abstract: A conditioning agent for textile fibres comprises the constituents of a product obtainable by reacting a mineral oil, a vegetable oil, and a fatty acid with sulphuric acid and then adding an alkali, an alkylolamine, and water, and also comprises an alkylated phenol, or an esterified vegetable oil, or tricresyl phosphate, or triphenyl phosphate.  The composition is useful for rendering fibres, including those of cellulose derivatives, amenable to carding, spinning, twisting, coning, weaving, knitting, or similar operations.  The composition lubricates the fibres and gives them a soft handle and it reduces the tendency of the fibres to take up electrostatic charges. Other materials may be included in the composition, e.g. softening agents, emulsifying agents, preservatives such as sodium phenyl phenate, fugitive or permanent dyes.  The mineral oil may have a paraffinic or naphthenic base, and the fatty acid may be oleic, ricinoleic, or palmitic acid.  In an example, white mineral oil, oleic acid, and a raw vegetable oil such as olive, rice, or peanut oil, are mixed and cooled to about 10 DEG  C.  Fuming sulphuric acid is slowly added, the temperature rising to about 20 DEG  C.  To the reaction product there is added diamyl phenol and then a mixture of triethanolamine, sodium or potassium hydroxide, and water.  The batch is stirred until all reaction ceases and a clear oil is formed.  Some of the raw vegetable oil may be added with the alkali if desired. Instead of diamyl phenol, there may be used dibutyl or diamyl derivatives of cresols, xylenols, or mono-chlorophenols.  The diamyl phenol may be replaced in whole or in part by tricresyl phosphate or triphenyl phosphate.  When the fibre or yarn to be treated contains organic esters of cellulose, the addition of an acetylated vegetable oil such as acetylated castor or olive oil, may be employed.  Instead of triethanolamine there may be used mono- or di-ethanolamine, diethyl-amino ethanol, ethyl diethanolamine, or 2-methyl-2-amino propanol.  The conditioning liquid may be applied to the fibres in the concentrated form, or in the form of an emulsion, or dissolved or suspended in a carrier.  Cellulose ester or ether filaments, staple fibres, yarns, bristles, straw, horsehair, or fabrics, or cellulose derivative fibres or filaments mixed with silk, wool, cotton, or regenerated cellulose fibres may be subjected to the treatment.

Abstract: 925,621. Specific-gravity estimating apparatus. HALLIBURTON CO. June 26, 1959 [April 2, 1959], No. 22079/59. Class 97 (3). [Also in Group XXV] The specific gravity of a fluid such as drilling or fracturing fluids or cement slurries is continuously measured or recorded by passing it through a looped conduit 13, Fig. 1, which is flexibly connected at 21 to fixed conduits 11, 12. Two pairs of flat leaf springs 17, 18, 19, 20, the springs of each pair being at right angles to one another, are connected between a saddle 15 fixed to the conduit 13 and a saddle 16 fixed to the conduits 11, 12, so as to constitute the pivot and the conduit 13 is counterbalanced by a weight 25 adjustably mounted on a shaft 26 attached to the saddle 15. Air under pressure entering line 36, Fig. 6, passes through filter 37 and restriction 38 to a valve 32, an indicating or recording instrument 40, and a bellows 31. The conduit 13, by means of a saddle 34, carries a flap valve member 33 co-operating with the valve 32 and saddle 15 engages the top of bellows 31, so that deflections of conduit 13 cause variations in the pressure in bellows 31 to rebalance the system and the pressure indicating or recording instrument 40 may be calibrated directly in terms of specific gravity. The zero position may be adjusted by rotating handle 30 and therefore rod 29 to cause a threaded block on the rod 29 to move to vary the tension in a spring acting on the saddle 15.

Abstract: 1,132,422. Wrapping-machines. G. HAIN. 12 May, 1967 [18 May, 1966], No. 22133/67. Heading B8C. In order to ensure complete removal of air from a wrapped package, e.g. of cheese, in which the wrapper is shrunk and/or sealed by heat, heat and pressure are applied to all surfaces except one which remains unsealed to permit exit of air and is finally sealed in the same manner as the others. Packages 10 are fed along a channel 17 from the main portion of a wrapping machine with an upstanding closure flap 15 trailing. They abut a heated plate 11 and are thrust by a pusher 4 into a channel 3 where the flap is folded down but not sealed. At the end of the channel, upper and lower heating plates 20 approach each other to engage opposed faces, then withdraw and permit a pusher 22 to feed the package between end wall heaters 27 reciprocated by means 28. Finally a pusher 31 moves the package past a heater 32 against which it is thrust by means 34 to seal the flap 15. A plate 36 cools the seal. All heating operations could be followed by cooling (not detailed). The wrapper may be treated with a mould inhibitor, e.g. sorbic acid. The device may be attached to the main portion of the wrapping- machine and be replaceable by one for handling different sized packages.

Title: Improvements in and relating to telegraph apparatus
IPC: H04L25/00
Filed: 1931-08-05
Abstract: 381,643. Telegraphy. GILL, H. A., 51, Chancery Lane, London.-(Fuld & Co. Telephonund Telegraphemverke Akt.-Ges., H. ; Frankfort-on-Main, Germany.) Aug. 5, 1931, No. 22187. [Class 40 (iii).] In a double-current telegraph transmitter the contacts are so arranged that the current in the line can be reversed without being interrupted by the operation of keying. In a start-stop transmitter the starting signal is given by the line L being connected to negative battery B1 and disconnected from positive battery B. To this end, contact is first made at k0 and then, 'after a brief interval, which may be one-tenth of a signal period, contact is broken at K0. During the brief period when both contacts are closed, current flows from both batteries through an inductive resistance r, which checks the flow of current in the local circuit and is dimensioned to suit the line. Preferably battery B1 is one-fifth stronger than B, and resistance r is one-fifth of the resistance of the line L. After.the starting signal has been sent, contact k0 remains closed and contact KO broken during the sending of five combination impulses. If the first of these is positive, contact Kl is first closed and then subsequently contact k1 is opened so as to cut off the line L from battery Bl. The contacts are interconnected as shown, so that a similar effect can be obtained with each combination impulse, and finally contact K0 is closed and k0 subsequently opened for the stopping signal. In a modification, Fig. 3 (not shown), the contacts k0 .. k5 are replaced by a single contact which is used in conjunction with each of the contacts K0 .. K5 in turn.

[Also in Division B8] A conveyer system comprises a track 13, Fig. 1, adapted to support one or more article carriers 14 and provided with one or more article carrier retarding devices 19. The latter comprise two members 20, 21, Fig. 2, mounted for relative rotation about a substantially vertical axis which provide vertically spaced opposed retarding surfaces 35, 36, Fig. 5, that converge relatively in the direction opposite to that of their rotation so as to compress therebetween a retardant liquid such as oil. The surface 36 supports the liquid and the member 21 is connected to an article carrier engaging element 39, Fig. 2. The arrangement is such that as the carriers 14 advance along the track 13 the member 21 is caused to rotate relative to member 20 such that a film of retardant liquid between the surfaces 35, 36 is subjected to pressure and thus effect retardation of the rotating member and the carrier 14. As shown the article carriers are advanced along the track 13 by dogs 18 on a sprocket wheel driven chain 10 which engage a bar 17 mounted on an upstanding stem 16 on the carrier. The carrier engaging element 39 comprises a central hub provided with a number, e.g. three, symmetrically spaced radial arms, the outer ends of which contact in turn the upstanding stems 16 on the carriers. The engaging element is rigid with a shaft 29 mounted in thrust bearings 28 on the other end of which is mounted the vaned member 21 which embodies a number, e.g. four, symmetrical radial arms each carrying a vane or paddle 33.
