Title: Improvements in or relating to a method of and machine or apparatus for drying coated sheet stock
IPC: B41F23/04
Filed: 1956-02-18
Abstract: 793,216. Drying coated sheets of paper &c. BLACK, J. A. Feb. 18, 1956, No. 5109/56. Class 34(2) [Also in Group XXX] A method of drying coated sheets of paper &c. consists in subjecting the sheets to a current of heated air and then allowing them to absorb moisture corresponding to room humidity prior to stacking. As shown, the sheets 138. Fig. 3, are dried by conveyance by racks 74 in a rightward direction over a table 33 formed by the top of a chamber 31 heated by hot air supplied through ducts 29, 30 disposed at the opposite sides of one end of the chamber and connected to an upper chamber 22 spaced a little above the table and containing vertically-adjustable, electric heating plates 35 over which air is circulated by a fan 27, Fig. 1, driven by an electric motor 28 and connected to a duct 25 communicating with the drying room. The racks are supported by end rollers 76, 77, Fig. 11, running on side tracks 66, 67 and are traversed through the narrow space between the chambers by endless-travelling chains 49,50 carrying projections 92, 93 for engagement with the racks. After passage over the table, the racks are transferred to a lower pair of tracks over which they are slowly traversed in a leftward direction by projections on a lower pair of endless-travelling chains with the sheets in a depending position to a point at which the sheets are automatically released from the racks and fall into a collecting tray 148. The slow movement of the racks over the lower tracks enables the sheets to absorb moisture corresponding to the humidity of the air in the drying room which prevents subsequent buckling of the sheets. The air is exhausted from the chamber 31 by a fan 139 into a shallow transverse chamber 142 having an outlet slot 32 from which the air issues in a jet which raises the sheets 138 into a vertical position as the racks are transferred from the upper to the lower tracks, the air then passing to an. outlet duct 26 having a damper 143 by adjustment of which a portion of the air is recirculated. The upper and lower tracks are connected at their ends by arcuate tracks 71, 72 to facilitate the transfer of the racks. Each sheet is attached to its rack by a gripper bar 81, Figs. 11, 12, secured at its ends to a guide arm 78 carrying a roller 79 running on a closed track at one side of the apparatus, and a block 80 freely mounted on the rack, and spring clips 89 also mounted on the rack and formed with slots engaged by pins 91 secured to the rack. Rigidly secured to each rack is a trip arm 86 which abuts against a stop 146, Fig. 3, to effect partial rotation of the rack to open the clips and release the sheet so that it falls into the tray 148. The trip arm is also actuated by cam mechanism to open the clips when the rack is transferred from the lower to the upper tracks at the left end of the apparatus, to permit the feed, either manually or automatically, of a fresh sheet to the rack.

Title: Improvements in or relating to the manufacture of a continuous match string
Inventor: ANDERFELT HARRY
IPC: C06F1/20
Filed: 1953-02-24
Abstract: <PICT:0725322/III/1> <PICT:0725322/III/2> In the method of making a continuous match string, for producing matches, by impregnating a strip or thread of a fibrous material in a bath of combustible material heated above the fusing point and compressing the strip or thread thus impregnated to a string, the string is compressed to a final square cross-section.  The latter may be effected by drawing the string through one or more draw plates provided with a hole of a square cross-section, or between four cylindrical rollers mounted one on each side of a square space, or by both methods.  The string may be pre-formed by drawing it through one or more draw plates with circular holes. In a suitable apparatus, a paper strip 1 from a coil 2 is passed through a funnel-shaped guide 3 to wrinkle it mounted on a heated container 4 for melted paraffin wax &c. and the strip passes therethrough to a draw plate 9 having a circular hole.  The string obtained then passes through a similar guide 11 and similar draw plate 12 to another guide 14 and from thence to a draw plate 15 having a square hole whereby the cylindrical string is transformed into one of square section.  The string is finally drawn through a compressing device 18 to a rotary drum 19.  The compressing device comprises four press rollers 21, 22, 23, 24, Fig. 7, having a press surface 25 and a width corresponding to the thickness of the string, the sides of the rollers being bevelled.  The rollers are mounted on shafts 26 supported on angle parts 27 attached to a plate having a pipe socket to be screwed into a plate 29, Fig. 1, supported on the container 4.

Title: Improvements in centrifugal electric switches
IPC: H01H29/26
Filed: 1946-02-19
Abstract: 608,309. Centrifugal switches; mercury and other liquid switches. LAMBERT, H. L. Feb. 19, 1946, No. 5194. [Class 38 (v)] In a centrifugal-switch a tube 3 extends into close proximity of the end of a housing 1 so as to provide a vent 5 into a sealed chamber 2, the housing being partly filled with a conducting-liquid 6, such as mercury, and partly by an inert gas, the gas-pressure within the tube 3 being greater than that outside, so that the liquid level therein is correspondingly lower. The switch is mounted on a frame 10, 11, 12 radially adjustable on a disc 13, rotation of which tends to equalize the liquid levels in the switch. At normal speeds the liquid bridges a pair of conductors 8, 9, but in the event of over-speed the level outside the tube 3 will fall sufficiently to break connection with the conductor 8. A float-element 7 is preferably disposed in the tube, to prevent the escape' of gas therefrom when the switch is inverted. In a modification, the liquid 6 may be non- conducting and the float 7 may operate contacts. In Figs. 4, 5 (not shown), the bottom of the tube is formed with U-shaped liquid-traps to prevent escape of the gas from the tube when the switch is inverted.

Abstract: 1,049,947. Seals. KLEINEWEFERS G.m.b.H., [trading as JOH. KLEINEWEFERS SÍHNE]. Feb. 7, 1964 [May 11, 1963 (2)], No. 5339/64. Heading F2B. [Also in Division D1] A device for the pressure-tight conveying through of web or strand material into or out of closed containers filled with gases or liquids, the pressure of which differs from the pressure of the air surrounding the container, or through a unilaterally open liquid-filled trough, is characterized in that two or more sealing strips 5 which act against each other under pressure are covered with a sliding foil 7 having good sliding properties relative to the material passing through. In the arrangement shown, processing container 1 is formed with an aperture 2 over which is a retaining device 3 housing sealing strips 5 which consist of a foam plastic core covered by sliding foil 7. One strip 5 may be acted upon by a continuous flat section 12 actuated by mechanical, pneumatic or hydraulic means such as the pressure chamber 9 shown. The strips 5 may alternatively be arranged inside the container 1 and acted upon by the pressure in the chamber with or without additional spring or other pressing means. In other embodiments the sealing strips are purely pneumatic being in the form of sealing diaphragms covered with sliding foil and acted upon by pressure either from inside the container or from separate means. In the latter case a pressure reducing device may be incorporated and arranged so that the pressure on the sealing strips is always above the pressure in the container 1. Instead of pneumatic pressure, hydraulic pressure may be used, the liquid in this instance may also be used as a coolant. Additionally such liquid may be used for the absorption of any gases which escape from the pressure chamber and a trough containing the liquid may be provided over the inlet and/or outlet for this purpose. In a further embodiment a multiplicity of pairs of sealing diaphragms in the form of flexible pressure tubes disposed in grooves and covered with a common sliding foil, are used. With this arrangement the pressure in the respective tubes can be varied from the inside to the outside of the device.
