Abstract: 301,981. Spree, J. H., and Baker, W. Sept. 23, 1927. Printing apparatus. -In apparatus for printing with artificial light, the sensitive paper is pressed against a set of coplanar negatives, each of which is secured in the open end of one of a series of compartments each enclosing a printing lamp the distance of which from the end carrying the negative is adjustable according to the density of the negative so that all the negatives may be printed simultaneously for the same length of time. The apparatus also comprises a metal masking plate for securing the negatives in position; a lower compartment into which the sensitive paper is discharged on releasing retaining means after printing; automatic means including a spring motor for illuminating the printing lamps for a predetermined period; and means for setting the timing device automatically when the pressure platen is withdrawn from the sensitive paper. As shown, a casing A having a hinged cover A<1> encloses a row of compartments D in each of which an electric lamp F is mounted so that it may be adjusted towards or away from a negative E held in the open end of the compartment by a thin metal masking frame E<1 >common to all the negatives. A diffusing screen D' may be provided in each compartment. A single sheet of sensitive paper, supported on fingers K<1> on a rotary rod K, is pressed against all the negatives by a padded hand- or lever-operated pressure platen H hinged to the casing A at H<1> and held when in closed position as by a catch J. In the casing A is a gap A<2> through which the printed sheets are discharged into a compartment L when the platen H is opened and the bar K is rotated by manual means external to the casing, in order to depress the supporting fingers K<1>. The lamps are connected through a plug Z to a circuit including two spring contacts Q, Q<1> of a timing- switch comprising a spring motor M controlled by an adjustable fan or governor on the shaft N of which is mounted an insulating disc 0 carrying a contact segment O<3> adapted on release of the motor to bridge the inturned ends of the spring contacts Q, Q<1>.

Abstract: 294,138. Armstrong Cork Co., (Assignees of Humphreys, C. F., and McCarthy, J. C.). July 18, 1927, [Convention date]. Right to Patent relinquished. Special fabric bases; ornamenting.-Felt base floor-covering material is printed on its surface with a coloured pattern and then embossed so as to depress certain of the colours to bring the pattern into relief. A printed floor covering of this type imitating tiling may for example be indented in the parts representing the mortar joints between the tiles. Preferably the pattern is printed before embossing. Oil paints may be used as the felt base does not become hard during the drying of the paint. Preferably the material is warmed slightly before embossing so as to render the bituminous composition with which the felt is saturated more plastic. The embossing may be effected before printing, particularly when shallow depressions only or formed, or when printing apparatus is used which could lay paint in the depressions. Fig. 4 shows a felt base floor covering printed with a tile pattern comprising tiles 2, 3, 4 of three colours, or of various shades of the same colour, separated by mortar spaces 14. Some of the tiles may be provided with printed designs. The printed spaces representing the mortar are depressed as shown in Fig. 5, the depressions being about 1/32 to 3/64 of an inch deep, and preferably of a smooth contour.

Title: Improvements in the method and means for making composition board
Inventor: MILLER HENRY C L
IPC: B27N3/14
Filed: 1956-08-24
Abstract: 806,214. Moulding resin-wood-chipboards. MILLER HOFFT Inc. Aug. 24, 1956, No. 25915/56. Class 87(2). In a process for forming boards, wood chips and a binder are fed from a hopper 54, Fig. 2, by parallel screws 56 through a spout 58 to produce parallel elongated mounds on a moving conveyer belt 44, which are levelled to a layer of uniform thickness on passage beneath a pair of rotating helical blades 32, 34, Fig. 3, which apply forces transverse to the direction of advance of the mounds, the rate of feed of the chips and binder being substantially in excess of that required to produce the uniform layer, the excess being removed and returned to the mounds, and the layer is deposited in trays 16. The latter are carried by a conveyer belt 14 between tapered press rolls 66, which shape and compact the edges of the layers, and between sizing or compressing rolls 18. The thickness of the resulting board may be controlled by adjusting a gate 64 at the outlet of the spout 58, and the height of the blades 32, 34 by adjusting bolts 26. The excess material removed by the blades 32, 34 is directed into a receptacle 74 (not shown) beneath the belt 14 and is returned to the hopper, 54. The helical blades 32, 34 are of opposite hand and are carried by shafts 28, 30 driven in the same direction by an electric motor through a chain (not shown) which also drives a rotary brush 38 at the end of the belt 44. Alternatively the helical blades 80, 82, Fig. 5, each comprise two parts of opposite hand meeting at points 84, 86 at different distances along the shafts 28, 30, respectively. In a further embodiment three layer forming apparatus are arranged in series above a single conveyer for the trays, for the manufacture of a laminated board having three layers which may be of different thicknesses and composition. U.S.A. Specification 2,740,990 is referred to.

Abstract: 1,003,755. Securing railway rails. RESSORTS DU NORD S.A. July 5, 1962 [July 13, 1961], No. 25922/62. Heading E1G. A rail flange is maintained in the lateral direction by a metal plate P carrying a projection 4 which engages in a recess 5 in a concrete sloper T. A spring clip A which bears at one end on the rail flange has a notch 17 at the other end which engages a longitudinal median rib 9 on the plate. The clip and plate are clamped on the sleeper by a bolt B. To accommodate varying track widths plates P of differing lengths are used, the distance between the axis of the bolt aperture 8 and the abutment edge 6 remaining constant so that a single size of clip A may always be used. The distance varied is that between the aperture 8 and the projection 4 and a passage 10 through the sleeper is wide enough to allow the bolt to be displaced within the limits of track widths. Engagement of a square-sectioned portion 15 of the hammer-head bolt B with a mortise 13 in an inverted U-section reinforcement 11 prevents rotation of the bolt whilst allowing lateral movement of the bolt along the passage 10. This arrangement is replaced by a coach screw when a wooden sleeper is used. The projection 4 may be integral with the plate or, as shown, comprise a block of elastomeric material.

Title: Automatic brake regulator for aircraft wheels and the like
IPC: B64C25/42
Filed: 1951-11-07
Abstract: 691,288. Fluid pressure brakes. SOC D'INVENTIONS AERONAUTIQUES ET. MECANIQUES S.I.A.M. Nov. 7, 1951. [Nov. 7, 1950; April 16, 1951; Sept. 24, 1951; Oct. 16, 1951], No. 26121/51. Class 103 (i). A skid prevention device for aircraft wheel fluid-pressure brakes of the type comprising an inertia mass or flywheel 12 rotatable on the shaft 13 of the wheel 14 and adapted to operate a switch 17 to actuate a brake-release valve 5 when the mass overtakes the wheel as a result of skidding and a switch 18 which is operated by the wheel when it accelerates to close the release valve 5 is characterized in that the circuit arrangements are such that once the brake release valve has been so brought into operation by the first switch, it remains operative until the second switch is actuated, despite reversal of the first switch. This action is brought about by the circuit shown in Fig. 2, the main part of which is contained within the control box 11 shown in Fig. 1. A time lag device 25 incorporating a bi-metallic strip prevents the electromagnet 10 which controls contact relays 23 and 24 from being fed for a period greater than 1-2 seconds. Figs. 3 and 4 show a particular embodiment of the accelerator in a compact form for fitting in a wheel hub. The fly-wheel 12 is mounted on bearings 29 within a casing 30 which is driven by the wheel through a torque-limiting friction device 31. The casing 30 itself rotates within a housing 34. A spiral spring 35 is connected to the casing 30 one end passing through the fly-wheel, and the other end forming a conducting finger 37 which co-operates with the conductor blocks 43, 45. Acceleration or deceleration of fly-wheel 12 deflects the spring so that the finger 37 co-operates with the conductor blocks 43, 45 to operate the relays in the control box 11 already described. A further embodiment in which provision is made for preventing incorrect running of the flywheel due to ground shocks is also described.
