Title: Improvements in and relating to the stabilisation of phenols
Inventor: MUNRO DUNCAN JAMES
Filed: 1956-07-06
Abstract: A phenolic composition comprises at least one monohydric phenol which is susceptible to atmospheric oxidation resulting in the formation of objectionable odour and/or colour and, as a stabilizer therefor, an effective amount of an amino acid, as such or in the form of a salt, present to the extent of less than 5 per cent by weight of said phenol.  Suitable salts of the acid group of the amino acid are alkali- and alkaline earth-metal salts and suitable salts of the amino group are salts of mineral acids, e.g. hydrochloric and sulphuric acids or salts of suitable organic acids.  Preferably the amino acids employed contain only one acidic and one amino group and they may be e.g., a -, b - or g -amino acids.  The phenol may be treated with the amino acid at any convenient stage in the manufacture of the phenol.  In the example crude liquid 4-methyl-2,6-di-tert.-butylphenol is mixed with methanol and the solid phenol is precipitated by the addition of water, an amino acid dissolved in water or methanol being added.  The precipitated phenol is separated from the mother liquor, dried and stored.  Amino acids and salts mentioned include anthranilic acid, glycine, N-methyl taurine, sodium-b -lauryl amino-propionate and sodium a  - methyl - b - laurylamino - propionate, l - cysteine hydrochloride, l-histidine hydrochloride and dl-alanine.

Filed: 1955-07-21
Abstract: 826,223. Agricultural sledges. AUSTIN. V. July 18, 1956 [July 21, 1955; March 9, 1956], Nos. 21142/55 and 7470/56. Class 108(1) An agricultural sledge towed behind a baling and so on machine receives the bales on a sloping platform comprising longitudinals 11, 16 and laterals 12, and is tilted to discharge the bales in a group to one side when the bales move against a lever 25. The lever 25 operates a linkage to swing a figure of eight lever 18 having spikes 24 into contact with the ground. the spike 24 acting as a fulcrum about which the lever 18 rocks to lift up one side of the sledge. When the lever 25 is pivoted, links 29 and 35 are pulled to pivot a bell-crank lever 31 away from a stop 40 on the lever 18, and move a lever 36 so that its end 38 pushes against one of a pair of abutments 41 on the lever 18 cooperating with stops 41e, thus causing the lever 18 to swing and drive one of its spikes 24 into the ground. Should the lever 18 bounce through one complete swing of 180 degrees instead of digging in a spike, or the tipping linkage become jammed by a bale, then the abutment 41 on the lever 18 may pivot anticlockwise upon engagement with the end 38 of the still operated lever 36 to prevent damage occurring to the linkage. Wings 43 are provided to guide the bales on to the platform and to prevent a bale not fully discharged from the baling machine from being tipped on to the ground. In a modification the bales are supported by a frame which tips relatively to the sledge body. In a further modification the lever 25 may be moved manually instead of automatically by pulling on a cord.

July 16, 1930, No. 21494. [Class 74 (ii).] To effect plain or normal plating the sinkers are moved inwards at such a time as to enable their nebs 2, which are unusually narrow and hook like, to penetrate between the ground and plating yarns prior to the engagement of the needles therewith. When the needles draw loops over the sinkers the ground yarn is drawn to the back of the neb and the plating yarn into the usual throat. To effect reverse plating the sinkers are moved inwards to such an extent that both yarns are drawn to the back of the neb. The penetration takes place as shown in Fig. 6, when the butts 7 arrive on the point 11 of the cam 9. The movement to effect reverse plating takes place in advance of the movement to effect normal plating and for this purpose jacks 13 slidable in the same tricks as the sinkers are selected to move forward and engage companion sinkers and move them to the position shown in Fig. 4. To permit early advance of selected sinkers the cam 8 is cut away at 15. The butts 7 thus moved forward of the cam face 10 are consequently not controlled thereby until they arrive at the point 16. The inclined edges 17 in conjunction with the downward pull of the needles cause the two yarns to assume the proper position for reverse plating at or near the point 16. To separate the yarns sufficiently to allow the nibs to penetrate between them, relatively adjustable guides may be used and the two yarns are fed out of opposite corners of the throat plate. The guide carrying the plating yarn is elevated except when plated or reverse plated fabric is being knitted. The leading portion of the guide is tapered and bevelled to act as a latch opener and closer. Fig. 16 shows an alternative form of sinker. Specifications 20101/09, 256,612, 278,383, 279,813, and 288,256, [all in Class 74 (ii), Knitting &c.], are referred to.

A plate-shearing apparatus comprises blades 3 and 4 for making straight and bevelled cuts, respectively, both blades being mounted on a beam 1 which is pivoted about two different axes 7 and 8 by a single piston-and-cylinder unit 6. The beam 1 is pivoted on a shaft 7 connecting side members of a rocker 9. Stub shafts 8 on the rocker are journalled in the machine frame 10 and open-sided bearings 11 are provided on the rocker to receive stub-shafts 12 on the beam 1. In operation, the piston-andcylinder unit 6 is actuated and the beam first pivots about shaft 7 whilst the blade 3 makes a cut. Engagement of the shafts 12 in the bearings 11 prevents further movement about shaft 7 and the beam and rocker then pivot about the axis of shafts 8 whilst the blade 4 makes a bevelling cut. The rest position of the rocker 9 and thus the initial position of the shaft 7, the blade clearance and the angle of the bevelling cut is variable by means of adjustment screws 13. Yieldable backing members 14 are compressed during the bevel-cutting stage and return the rocker 9 to its rest position during retraction of the beam 1 by the piston-and-cylinder unit 6.

Abstract: 1,039,257. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. May 21, 1965, No. 21600/65. Heading H1K. In the manufacture of a semi-conductor device a layer of semi-conductor material is grown on one face of a semi-conductor wafer on the other side of which is grown or deposited an insulating layer which, after the formation of the semiconductor device in or on the grown semiconductor layer, is bonded directly or indirectly to a metallic member which may form part of the device encapsulation. In one embodiment a medium resistivity layer of N-type silicon is grown on one side of a low resistivity wafer of the same material. The other side of the wafer is lapped to reduce its thickness. The body is then heated in oxygen saturated with steam to produce silica coatings on both faces. A very high resistivity layer of polycrystalline silicon is then deposited on to the silica coating on the lapped surface. On the other side of the body transistors are fabricated in the grown semiconductor layer by use of the planar process. The wafer is diced after evaporated and alloyed aluminium contacts have been provided for emitter, base, and collector of each transistor. Each die is bonded to a metallic header with gold or solder glass. In a second embodiment the starting wafer is of high resistivity and is of the opposite conductivity type to a low resistivity semi-conductor layer grown on one of its faces. A medium resistivity layer is grown in ohmic contact on the first grown layer and semi-conductor devices made in this second layer. An insulating layer is deposited or grown on the other wafer face. The structure may be bonded to a metallic header either by a metallic layer graded from chromium at the insulating layer to gold at the header, or by solder glass. Semi-conductors other than silicon may be used and silicon nitride or silicon monoxide may be used as the insulating material. Methods other than diffusion may be used to make the devices, for example localized epitaxial deposition or alloying.

Abstract: 463,025. Sewing - machines. MAUSERWERKE AKT. - GES. Aug. 6, 1936, No. 21682. Convention date, Sept. 20, 1935. Addition to 460,337. [Class 112] The differential-feed device described in the parent Specification is provided with with manually or pedally-operated means for varying the differential effect while the machine is in motion. The feed stroke of the main feed dog 2 remains constant as determined by the adjusted position of the end of the arm 15 in the slot in the rocker arm 18. The feed stroke of the auxiliary feed dog 3 is varied by moving the end 54 of the arm 24 in the slot 26. This is effected during operation of the machine by rocking an external lever 40 on the shaft 12. This causes a second arm 38 to raise or lower a link 37 fixed to the feed arm 24 at 36. Preferably a pair of stops 45, 46 are adjusted in a graduated slot 49, so that for normal working, the spring 42 presses the arm 40 against the upper stop and so ensures a constant degree of difference of feed between the dogs. To alter this difference to suit the work, the lever 40 is, at the appropriate time, depressed by hand or foot to engage the lower stop, so altering the stroke of the auxiliary feed dog 3. On releasing the lever 40, the spring returns it to its former position.
