Abstract: 187,740. Colman, T. B. Aug. 8, 1921. Revolving doors.-Revolving compartment doors have wings adapted to collapse when subjected to abnormal pressure. Each wing consists of two universally-hinged parts 1<a>, 1<b>, the part 1<b> being hinged on ball-bearings between collars 2b, Fig. 8, on a shaft or column carried by a beam above the rotating soffit. The wings are held in the central position by spring-pressed studs 12, Fig. 4, carried by a plate on the central ballbearing of the soffit and engaging open-ended slots 11 in the top edge of each wing-member 1<a>, and by spring-pressed studs adapted to engage recesses in a pivoted plate at the axis of the door and at ground level.

Alternative means for holding the wings in the central position comprise arms 25, Fig. 14, having studs engaging a plate rotatably mounted on a casting in the ground and having a pin-and-slot connection with the 'bottom edge of the door. The wing is allowed to fold under abnormal pressure by means of a cam-guide on the pin 28 engaging the holding rod 25 and raising same when the wing parts are folded. The wings may be supported on arcshaped guideways 33, Fig. 13b, by pins 36 con. nected to an undercut slot in the door and having a ball-bearing on the rails. The columns 2<a>, Fig. 6, have an adjustable bolt 17 connected to an arcshaped piece 13 housed in a ring 14 sunk in the ground, the pieces 13 being connected by segments forming a closed ring, so that the columns move together. Woodwork carrying draught-excluding means is attached to the hinges 2. A spring-controlled yielding latch 39 connects opposite pairs of wings together, Fig. 15; on first moving the wings apart, the latch is drawn along the pin 41 against the spring 44 until the camshaped slot 42 and pin 40 free the latch from the engaging recess 43.

Patent GB-591593-A (GB)
Title: Improvements in the finishing of textile materials
IPC: D06M13/224
Filed: 1944-10-30
Abstract: A light-weight textile fabric is treated with a drying oil which is thereafter air-dried on the fabric, the amount of air-dried oil product incorporated therein being 10-35 per cent of the weight of the fabric so that the yarns are coated without closing the interstices of the fabric.  The treatment improves the apparent transparency or sheerness and the uniformity of lustre. It also increases the resistance to laddering particularly in the case of hosiery.  The fabric may be subjected to a preliminary clarifying treatment with water and a hydrophobe liquid.  The materials may be damped with water and then steeped in benzene until they appear clear in the liquid.  The drying oil may be applied as a solution in a volatile solvent, e.g. a 10 per cent solution in benzene.  If desired, the clarifying treatment and the oiling treatment may be combined, the oil being applied in solution in the hydrophobe liquid used, in conjunction with water, to treat the materials.  Other specified solvents for the drying oil are toluene, xylene, solvent naphtha, light petroleum fractions, carbon tetrachloride, and perchlorethylene.  The drying oil may be linseed or tung oil, or a varnish consisting of a drying oil modified by means of a resin.  The treatment may be applied to natural or regenerated cellulose textile fabrics particularly hosiery, e.g. of cotton, viscose or cuprammonium rayon, or regenerated cellulose from stretched cellulose ester yarns. It may also be applied to fabrics of natural silk or of cellulose esters or ethers.  After applying the drying oil solution, the fabric may be squeezed and then hung in a steam-heated oven at 75-85 DEG  C. for 24 hours.  Specification 591,594, [Group VIII], is referred to.

Title: Ceramic pigments
IPC: C09C1/00
Filed: 1973-05-04
Abstract: 1419166 Ceramic pigments DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 4 May 1973 [5 May 1972 (2)] 21272/73 Heading C1M A ceramic pigment comprises a sulphide, selenide or telluride of Zn, Cd or Hg or a mixed crystal thereof incorporated as a discrete phase into transparent crystals of a glaze-stable substance. Pigments in which the glaze-stable substance is zirconium silicate are specifically disclaimed (Specification 1,403,470). Suitable glaze-stable substances which may be coloured are ZrO 2 , SnO 2 , CeO 2 , CePO 4 , Al 2 O 3 , (Zn, Mg, Co, Ni) (Al, Cr, Fe) 2 O 4 , CaSnSiO 5  and the specific examples disclose pigments based on SnO 2  and Al(OH)3. The sulphides, selenides and tellurides may be formed during the synthesis of the glazestable compound. Zinc, cadmium, mercury and sulphur in the form of their oxygen containing compounds are preferably used as starting materials for this purpose. For example when a mixture of SnO 2 , CdO and Na 2 SO 3  is heated at 1200‹ C. with a lithium halide as mineralizer, the SnO 2  crystals grow and incorporate yellow CdS. Cd(S, Se) can be similarly incorporated into Zn(Al, Cr) 2 O 4  forming a chrome pink when cadmium sulphide selenide is formed slowly during the synthesis of spinel from ZnO, Al 2 O 3  and Cr 2 O 3 . Numerous cadmium compounds, e.g. CdCO 3 , CdSO 4 , CdO, CdS and CdSe and sulphur/ selenium containing compounds, e.g. Na 2 SO 4 , Na 2 SO 3 , Na 2 S 2 O 5 , Na 2 S 2 O 3 , Na 2 S 2 O 4 , Na 2 S or the corresponding selenium salts and their mixed crystals are specified. Reducing agents, e.g., sugar and starch, together with LiF, Na 2 AlF 6  and Na 2 B 4 O 7  may be added and the colour of Cd(S x Se 1-x ) inclusions may vary through orange, light red, dark red to black (x=0). The specific examples describe the preparation of pigments comprising Cd (S, Se) incorporated into transparent crystals of SnO 2  (1, 2) and Cd (S, Se) incorporated into transparent crystals of Al 2 O 3 .

Abstract: 837,806. Sewing machines. UNION SPECIAL MACHINE CO. July 12, 1956 [July 15, 1955], No. 21533/56. Class 112. A lock stitch machine, Fig. 1, is provided with interconnected drive shafts 14, 46, arranged longitudinally of the arm and the base, a needle-bar 20 which swings in the line of feed for imparting feed movement to the work, a rotary hook mounted on a vertical axis, and a continuously rotated feed wheel 105 mounted on a horizontal axis adjacent the hook. Feeding work by needles. The needlebar is mounted for reciprocation in a frame 22 mounted on a pivot 24 and carrying a pin 25 connected by a link 26 to an arm 27 on a hollow shaft 28 journalled in bearings 29, 30 and carrying the bearing bushes for the shaft 14. A bracket arm 31 secured on the shaft 28 has a bearing member 31a, Fig. 10, pivoted to its lower end. A pin 32 slidingly mounted in the bearing member 31a and a bore in the strap 33 of an eccentric 34 on the driving shaft 14 carries a block 35 pivoted at 36 to a block 37 on a vertically adjustable rod 38. The eccentric rocks the bracket 31 to swing the needle-bar and the position of pivot 36 may be raised or lowered to vary the amplitude of the feeding movement by raising or lowering the rod 38 by means of the adjusting screw 39. Feeding work by wheels. The feed wheel 105, Fig. 1, is mounted on a shaft 100 carried by a bracket 102 mounted for vertical adjustment in a frame 70 mounted by means of a split extension on a bearing sleeve 72 of the driving shaft 46 so that it may be adjusted angularly and longitudinally thereof.
