Abstract: 195,182. Wakefield, H. R., Terry, E., and Rowlatt, J. Jan. 5, 1922. Coating bakers' goods.-In a bread slicing and buttering machine, the loaf is carried in a vertical holder which is reciprocated beneath a butter-holder 36 prior to the slicing operation. The butter-holder 36 is preferably vertical and contains a spring-pressed plunger, the pressure being controlled by a sleeve 47 which is depressed by a rack 48, wheel 49 and handwheel 51 and is held by a rack 52 and detent 53. The plunger. sleeve, and operating means may be swung clear to facilitate charging with butter. The outlet is regulated by a sliding plate 69 with a slot which is positioned below the outlet when the loaf is passing, and a wiper 84 being provided. An oscillating plate 54, operated by a gear-wheel 56, rack 57 on a lever having a roller 60, and a cam 61 on the bread-holder, forces a portion of the butter through the outlet. The plate 54 is returned by a spring 62 and an arm 58 and the roller end of the cam-lever is knuckled to allow the roller 60 to rise over the cam 61 on the return stroke. The plate 69 is operated by a cam 72, on the bread-holder, through a roller 71. and levers 70, 78, which are returned by springs 79, 80, the amount of movement being varied by a milled wheel 74 which is connected, through gearing, with an eccentric pivot 73 on which the lever 70 is mounted. The butter supply may thereby be cut off, the plate 54 then being rendered inoperative by a cut-out handle 67 which interposes a block between the knuckle-end of the cam-lever and the lever itself, thereby keeping the roller 60 clear of the cam 61. An indicator 75 is provided with graduations corresponding with the readings of a thermometer 77. The bread-holder is reciprocated across the butter-receptacle and the disc knife 17 by a crank 5 and connecting-rod 6. A conveyer 29 removes the slices to a receptacle 30.
Patent GB-595344-A (GB)
Title: Improvements in the art of printing textile yarns and fabrics containing cellulose acetate
IPC: D06P3/40
Filed: 1945-01-17
Abstract: Yarns and fabrics of secondary or acetone-soluble cellulose acetate are printed with a paste containing a dyestuff as hereinafter defined, a thiocyanate and a liquid organic swelling agent, excluding the lower monohydric aliphatic alcohols. Suitable dyestuffs are those which colour the materials when the latter are immersed in a dye bath containing 10 per cent of ammonium thiocyanate and 16 per cent of ethyl lactate for 10 minutes followed by washing, soaping, rewashing and drying and, in the case of Rapidogen, Indigosol or azoic dyestuffs, the appropriate after-treatment.  Many such dyestuffs are specified. The liquid organic swelling agents which may be used are ketones, esters and alcohols (other than lower monohydric aliphatic alcohols) which are liquid at ordinary temperatures, which p preferably have boiling points above 100 DEG  C. and which cause swelling of secondary or acetone-soluble cellulose acetate, e.g. ethyl lactate, diacetone alcohol, methyl cyclohexanone, dimethyl phthalate or Reomal P.  A typical printing paste contains 20 parts of dyestuff, 160 parts of methyl cyclohexanone, 100 parts of ammonium thiocyanate, 550 parts of British Gum (4 lbs. per gallon of water) and 170 parts of water.  After drying, the printed material is preferably steamed for 15-20 minutes.  Mixed yarns of cellulose acetate and viscose or cotton are dyed solid colours by means of substantive dyestuffs; mixed acetate and wool or silk are dyed solid colours by means of acid dyers; and mixed acetate and viscose are dyed solid colours by means of acid dyes in the presence of urea. Differential effects may also be obtained.  In an example, the material is printed with an Indigosol dyestuff as above, dried and developed in a bath containing sodium nitrite and sulphuric acid.  In a further example, material printed as above with a Rapidogen dyestuff is dried and developed in a bath containing acetic acid, formic acid and Glauber's salts.  In another example, the material is printed with an azoic colour, dried and coupled with a neutralized diazotized fast colour base, e.g. Brentamine Fast Red B base. Specification 588,106 is referred to in the first and second Provisional Specifications and Specification 592,858 in the second Provisional Specification.

Title: Measuring the degree of alignment of fibres
IPC: G01N27/22
Filed: 1976-03-29
Abstract: 1534684 Measuring alignment of fibres DEFENCE SECRETARY OF STATE FOR 29 March 1976 [6 Jan 1975] 497/75 Heading G1N A method of measuring the degree of alignment of the fibres in the plane of a mat of nominally aligned electrically conducting fibres which are not in good electrical contact with each other comprises measuring the dielectric constant of the mat in the plane thereof in two mutually orthogonal directions, one direction being parallel with the nominal direction of alignment of the fibres, and comparing the measurements obtained of dielectric constant. A pair of printed circuit boards 10, 20 are disposed to sandwich the mat 30 therebetween. The board 20 is a mirror image of that 10, shown in Fig. 1a and having inter-digitated comb-like electrodes 14, 16, which are aligned with those 24, 26 of the board 20. The electrodes are connected in a bridge circuit to measure the capacitance between electrodes 14 and 16 and between those 24 and 26 in the plane of the mat. Pressure up to ten p.s.i. may be applied to ensure consistent measurements of capacitance. The dielectric constants of the mat measured as above are considerably higher than that of the bulk material of the fibre. Thus for an asbestos fibre the measurements were 135 and 75 parallel and perpendicular to the nominal direction of alignment measured in the plane of the mat, whereas the values found using a parallel plate condenser technique were 8À0 parallel to the fibres and 5À3 perpendicular to them. It is stated that the measured deviation from the ratio, for perfect alignment in a given material, of the values measured parallel to and perpendicular to the nominal direction of alignment indicates the degree of misalignment among the fibres.  The arrangements of Figs. 5(a), (b) (not shown) use guard electrodes. To avoid the need to rotate the circuit boards, by 90 degrees relative to the mat or vice-versa, between measurements four sets of inter-digitated electrodes (62, 64, 66, 68) may be provided in two pairs arranged orthogonally of one another, Fig. 4(a) (not shown). For circularly aligned fibres an array of four sets of electrodes are provided on each board with the electrodes of one pair of sets disposed radially (72, 78) and the others (74, 76) disposed in concentric arcs, Fig. 4(b) (not shown).
