IPC: A47C1/10
Filed: 1931-05-28
Abstract: 369,079. Head - rests. MITCHELL, T. W., Brussels, Ontario, Canada. May 28, 1931, No. 15580. [Class 52 (ii).] An adjustable head-rest comprises a telescopic element provided between the pad and the stock and consisting of an outer member slidably mounted in the stock and an inner member secured to the pad, teeth being provided on both the inner and outer members together with click and pawl means on the stock for engaging said teeth. Such a device is shown in the drawings, comprising a pad 14, stock 15, and two telescopic elements. Each telescopic element comprises an inner member 25 on the pad, and an outer tubular member 26 slidable within the stock. The members 25, 26 are toothed at 30, 31 and the teeth 31 are longitudinally interrupted by a slot so that the stepped clicks 34 can engage both sets of teeth. The clicks are pressed outwards by the spring 35 and can be withdrawn by pressure upon the button 39. The teeth 31 are made deeper than the teeth 30 so that the member 26 cannot be withdrawn until the member 25 has been withdrawn to its extreme position.

Filed: 1975-04-16
Abstract: 1485090 Wrapping confectionery GD SpA 16 April 1975 [17 April 1974] 15619/75 Heading B8C To process confectionery products of predetermined parallelepiped shape and size wrapped in single-point style with the points folded over on to the major surface of the product at which the longitudinal edges of the wrapper overlap, the wrapped products are passed to an intermittently movable conveyer 19 from a rotatable wrapping head 14, the conveyer having pockets 18 to receive and exactly house a wrapped product, and are then conveyed to a pressing station where a member 21 presses against a housed product to flatten the wrap, to enhance the fold lines, and to regulate the thickness of the wrapped product. As shown a continuous length of confectionery rope is shaped by walls 3 and discs 4 and advanced by rollers 5 to be cut at 7 and fed intermittently to guides 11 to engage a cutting of wrapping material fed vertically into a slot 12 from reels 13. Wrapping is performed by the rotatable head 14 which has fixed and oscillating fingers, the wapped products then being passed to the pockets of an intermittently rotatable conveyer 19. At successive stations around the conveyer the product is pressed by a vertically reciprocable member 21, the wrapper is heat sealed by an electrical heater plate 28, cooled by a watercooled plate 42 and ejected by a vertically reciprocable member 51. Should the apparatus stop, electromagnets 30 are de-energized automatically so that the heater plate 28 is raised from the conveyer 19 by a spring 34.

Abstract: 440,994. Tyre-building machines. DUNLOP RUBBER CO., Ltd., 32,Osnaburgh Street, Euston Road, London, and WILLSHAW, H., and BLANCHARD, L. S., c /o Dunlop Rubber Co., Ltd., Fort Dunlop, Birmingham. May 30, 1935, No. 15702. [Class 144 (i)] A machine for rolling-down the tread or other tyre components on a rotary building- drum comprises spinning-discs 16. 19 engaged by a right-andleft threaded spindle 1, the traverse of the discs in both directions being controlled by the relative angular velocities of the discs and the spindle. In the operative traverse, the discs are rotated by contact with the drum and in the reverse direction they are automatically braked, the spindle being driven continuously in the same direction of rotation. In the apparatus shown. the spindle 1 is mounted between the arms 2, 3 of a yoke 4 arranged to be rocked towards the drum by the piston of a power-cylinder 5. The latter is fitted with a distributing-valve 23 which is normally moved to exhaust by a spring 31, and moved to admit fluid to the cylinder by means of a hand-lever 24. A detent device 27, 28 holds the lever 24 in the latter position until disengaged by abutment of a brakemember 21 with the spring-loaded rod 29 at the end of the operative traverse of the discs. In this movement, the shoes 21 are separated, by the pressure of the discs, against the pull of springs 22. On the release of the detent and the lever 24, the valve 23 is operated to exhaust the cylinder 5, and the yoke 4 falls (by gravity) to move the discs away from the drum. The brakes 21 are then operative to hold the discs against rotation in which condition they are moved to the initial position shown by the continued rotation of the spindle.

Filed: 1949-06-13
Abstract: Wool, silk or fibres made from casein, zein or peanut protein are treated with a non-tertiary alcohol containing not more than 4 carbon atoms in the molecule in the presence of an acid-reacting catalyst and are then dyed with an acid dyestuff.  The alcohol should not contain more than 25 per cent of water and preferably less than 5 per cent.  The acidic catalyst, e.g. hydrochloric acid, sulphuric acid, boron trifluoride, silicon tetrachloride, acetic anhydride, acetyl chloride or sodium hydrogen sulphate should have an equivalent acid concentration between N/5 and N/50, preferably about N/10.  In examples: (1) wool is boiled in methanol containing hydrochloric acid, rinsed and dyed with Azo Geranine B from an acid bath; (2) the hydrochloric acid in (1) is replaced by acetyl chloride; (3) n-butanol at 90 DEG  C. is used in place of boiling methanol; (4) wool treated as in (1) is mixed with untreated wool and dyed with Azo Geranine B at a pH of 5.5, whereby the former is coloured and the latter remains white; (5) the previous example is repeated but dyeing is conducted at pH 4; (6) Azo Geranine B in (4) is replaced by Neolan Blue GG; (7) Azo Geranine B in (4) is replaced by Carbolan Crimson BS; (8) wool treated as in (4) is dyed with a mixture of Neolan Blue and Azo Geranine B; (9) wool is heated with glycerol containing hydrochloric acid and dyed as in (1); (10) regenerated protein fibre is treated with ethanol and hydrochloric acid as in (1); (11) the previous example is repeated, using natural silk; and (12) example (3) is repeated using ethylene glycol, n-propanol, isopropanol, and secondary butanol.  The Provisional Specification refers also to the use of other alcohols, and specifies cetyl alcohol, benzyl alcohol, 1,4-pentanediol and glycerol.

Title: Improvements in or relating to the seamless coating of printing formes, with specialreference to impression cylinders for photogravure
IPC: G03F7/18
Filed: 1954-05-31
Abstract: <PICT:0787328/III/1> Printing formes or cylinders are coated in the vertical position with a colloid solution by withdrawing them longitudinally from a container into which the colloid solution has been introduced from the bottom and maintained at a constant level, and subjecting them at their freed ends to heat.  As shown, an impression cylinder 3 is placed in a tubular container 1 having a constant temperature jacket 2 and a pistonlike slidable bottom 4, through which passes an inlet 9 connected to a liquid reservoir 10 by a flexible tube 14, the impression cylinder 3 being secured to the bottom 4.  The colloid solution is introduced upwardly from the reservoir by compressed air admitted through the tube 11.  The inlet is then closed by a valve 12 and the cylinder, together with the bottom, is slowly raised, the coating on the cylinder being dried by a heated cylinder 8.  The solution which is carried up by the piston is returned through the overflow pipe 6 to the reservoir, thus keeping the level in the container constant.

Convention date, June 6,1934. [Classes 80 (ii) and 80 (iii)] A constant-velocity universal joint for intersecting shafts A and B, Fig. 1, comprises a pair of ball-and-socket joints, the parts 11, 13 of each of which are carried by a pair of forked arms 12, 14 of equal length pivoted on the two shafts about axes which intersect the axes of the shafts at right-angles. A central ball-and-socket joint 15, 16 may be arranged between the shaft ends at their point of intersection. The two arms associated with each shaft may be pivoted about the same axis, as shown in Fig. 1. Where, however, one of the shafts has a nutating movement, the two arms associated with each shaft are pivoted about axes disposed on opposite sides of the point of intersection of the shafts, as shown diagrammatically in Fig. 6, so as to preserve balance. Thus, in the case of a swashplate mechanism in which pistons 28, Fig. 8, slidable in a rotating cylinder block 26, act upon a plate 27 mounted loosely on an inclined portion 29 of a shaft D, a universal joint between the block 26 and the plate 27, which act as the shafts A and B respectively, comprises ball-and-socket joints 18 and 19, the parts of which are carried by forked arms 201, 202 and 23<1>, 23<2> pivoted about pins 21, 22 and 24, 25 respectively, the pins 21, 24 being carried through supports 30 by the block 26 while the pins 22, 25 are carried by the disc 27.
