Abstract: 1357185 Cladding panels W J SILBERKUHL 10 June 1971 [3 March 1970] 19851/71 Heading E1B A prefabricated roof panel tile or wall panel is formed of asbestos cement or fibre reinforced plastics and is generally channel shaped and is longitudinally bowed. The channel 6 may be convex, or concave upwardly and is bounded along its longitudinal edges by relatively inverted channel flanges 5 of smaller associated amplitude and wavelength than the channel 6. The flanges 5 may be longitudinally bowed so that the central channel 6 decreases in depth from the centre towards each end of the panel where it terminates in substantially flat end supporting edges. Alternatively the flanges 5 may be straight and the panel longitudinally bowed in the opposite sense to provide the decrease in depth towards the ends. The channel 6 may be formed with a central reinforcing ridge formed as a downwardly opening channel decreasing in amplitude from the ends to the centre of the panel. The reinforcing fibres may be orthogonal and at an angle of between 30‹ and 45‹ to the long axis of the panel.

Title: Improvements in or relating to automatic track relay signalling systems for railways
IPC: B61L23/16
Filed: 1936-07-21
Abstract: 473,717. Railway signalling systems. VEREINIGTE EISENBAHN-SIGNALWERKE GES. July 21, 1936, No. 20213. Convention date, Aug. 10, 1935. [Class 105] A track-circuit signalling system has each section provided with two stick track relays each of which is picked up over a back contact of its associated relay or by a front contact of an auxiliary relay energized over series back contacts of the two track relays. In the arrangement shown the two track relays 10, 20 are of the two-element type and have their local windings 14, 24 maintained energized over their stick contacts 11, 21. Entry of a train drops the two track relays 10, 20 which by their back contacts 12, 22 energize an auxiliary relay 50. Front contacts 51, 52 of the auxiliary relay 50, energize the local windings 14, 24 of the track relays which accordingly pick up as soon as their track windings 15, 25 receive current on the section becoming free. The current is not applied to the track rails of section 2, until the signal for section 3 has gone to danger and so has closed a contact 8. When this signal subsequently returns to the clear position the track current is applied, as shown for the signal of section 2, over front contacts 13, 23 of the track relays and a back contact 53 of the auxiliary relay. If one track relay fails to drop then a green lamp remains energized with the red lamp and so gives a " disturbance " indication. Singleelement relays may be used, Fig. 2 (not shown). With long sections one relay may be energized over a short entrance section or over a track contact.

Abstract: 478,662. Time switches. I. G. FARBENINDUSTRIE AKT.-GES. July 22, 1936, No. 20301. Convention date, Aug. 14, 1935. [Class 38 (v)] A switch specially adapted to close the circuit to a photographic printing device for a predetermined time comprises contacts in an evacuated container 1, a tilting operating rod 2 for the contacts and a weight-controlled timing device for actuating the rod 2. To operate the device a weight 4 on a rack 3 is first raised to the position shown. During this movement a ratchet wheel 10 driven by the rack 3 slips idly past a pawl 9. The weight is then allowed to fall' and the rack drives through the ratchet and pawl device 9, 10, a wheel 6 in gear with escapement mechanism 7, 8. so that the weight and rack fall at a predetermined rate. At the beginning of this movement a pin 11 on the rack 3 moves away from a lever 12 which moves to the left about its pivot 12b and withdraws a pin 12a from the rod 2 allowing the contacts of the vacuum switch 1 to close. The rack now falls an adjustable distance determined by the setting of a cam 13 provided with a dial plate. At the end of this distance a pin 16b on a lever 16 pivoted at 16a on the rack strikes the cam. The lever 16 is rotated and presses a lever 19, pivoted at 19b, to the right so as to release a pawl 22 which falls so as to engage a ratchet wheel 23 and stop the clockwork. The end 22a of the pawl 22 also engages the pin 12a and rotates the lever 12 so that it presses on the rod 2 and opens the vacuum switch. In resetting a pin 24 on the rack lifts the pawl 22 into the original position..

Abstract: 224,300. Mitchell, J., and Cossey, J. C. G. Aug. 10, 1923. Addition to 185,602. Combined buffer and draw-gear.-In a central coupling for railway and like vehicles, as claimed in the parent Specification, the draught and' buffing springs are enclosed in a draught yoke member slidable in the underirame. The yoke 2 encloses the combined buffing and draw-spring 21 and rests at its front end on a guide 6 attached to the headstock. The ferrule 4 slides in the front portion of the yoke 2 and abuts at its front end against the rear end of the coupler 18 and at its rear end against the front follower plate 22. The rear end of the ferrule 4 and the front portion of the yoke 2 are shotted to accommodate the T-head 14 of the draw-bar 5. The rear end 3 of the yoke 2 is semi-circular and is provided with an integral housing 27 for the centring spring 26 which surrounds a guide-bar 28 which passes through both follower plates and centralizes an auxiliary spring 21<a>. When the coupler is under draught the T-head 14 engages the end of the slot in the yoke and draws the yoke forwardly until the spring 26 is compressed sufficiently to enable the housing 27 to abut the rear follower plate 23. The rear follower plate then leaves its abutment on the underframe and compresses the springs 21, 21<a> against the front follower plate. In buffing, the ferrule 4 is forced rearwardly against the front follower plate 22, which compresses the springs 21, 21<a>.

Abstract: Wood is rendered fungus-, insect-, bacteria-or fire-proof by gradually immersing in a liquid bath containing a fungicide, insecticide, bactericide or fire resistant agent at a temperature in excess of the boiling point of water and sufficiently high to cause the moisture in the wood to escape under pressure to leave the cells in the wood in an enlarged condition thereby enabling the said liquid to penetrate into the cell structure of the wood and deposit the proofing agent therein, the supply of liquid to the bath being controlled at a rate which avoids exploding of the wood.  The wood may be secured in a container to prevent floating and an aqueous solution of sodium silicate, pentachlorophenol, sodium fluoride, magnesium chloride, magnesium carbonate, calcium chloride, potassium silicate, potassium fluoride, sodium bichromate, sodium arsenate, sodium pentachlorophenolate, magnesium chlorate or calcium chlorate, which has been preheated under pressure pumped in.
