Title: Improvements in or relating to children's cots
IPC: A47D11/00
Filed: 1947-04-01
Abstract: 622,610. Cots ; play-pens. MARJAMAA, K. E. A. April 1, 1947, No. 8822. Convention date, April 2, 1946. [Class 52 (i) and 52 (ii)] A child's cot is convertible into a play pen having an area larger than that of the bottom of the cot which bottom can be extended to form the bottom of the play pen. The cot comprises two fixed ends, a fixed side 3 and a bottom 7 the remaining side of the cot being closable by two half-sides 4 connected to the respective ends of the cot so as to be swung open when required. The bottom 7 of the cot has superposed on it a board 9 provided, on its upper side, with a mattress such as a spring wire mattress 8. To convert into a play pen the half-sides 4 are swung open, the board 9 with its mattress is reversed and arranged alongside the cot bottom 7 and the free ends of the half-sides are closed by an additional side 11 which is housed below the base board 7 when the play pen is re-converted into a cot. The bed clothes &c. may be secured to the mattress so that they are stored in the space below the bottom of the play pen.

[Class 34 (ii)] In buildings for withering tea, comprising a bulking chamber communicating with one or more lateral withering-lofts, air-conditioning plant is disposed within the bulking-chamber and includes a shield arranged to allow free access of the air to substantially the whole of the side of the chamber. Fans 2, Fig. 1, at one or both ends of the bulking- chamber 1 draw unconditioned air through electric heaters 5 and deliver it to an inverted channel-shaped shield 3 laterally open at the bottom, the air passing also through water sprays supplied by longitudinal pipes 4. Controlled openings 6, leading to the withering-lofts on either side, are preferably covered by perforated plates or otherwise designed to pass equal quantities of air. If the pressure distribution in the chamber 1 is non-uniform, the number or size of the openings 6 is locally varied to equalize the air-flow to the lofts. The heaters 5 may alternatively be situated near the sprays, just outside the shield 3. In the modification shown in plan in Fig. 5, a duct 7, 14 is open at both ends and contains, in order, a heater protection screen 8, heaters 9, water-spray screen 10, spray nozzles 11, surplus water trap screen 12, and fan 13. The air-conditioning plant may comprise various other combinations of elements.

Abstract: 249,329. Borroughs, J. N. April 6, 1925. Towel rollers. - In a towel cabinet of the type in which the lastused portion of a towel hangs in a loop outside the cabinet 1, Fig. 1, and in which the towel is fed from a supply roller 10 over guide rollers 30, 31 provided respectively with pressure rollers 46, 50 to a take-up roller 16, a shield 62 normally rests in front of the last used portion of towelling but is displaced when the rollers feed the webbing. Driving means for the feed rollers include a reciprocating operating element which is only operative in one direction of movement. The shield 62 is raised by a treadle 64 and a cord 77, a second cord 78, Fig. 3, connected to a spring-controlled chain 80, simultaneously rotating the rollers 10, 16, through a pawl 44 on a sprocket wheel 40 and gearing 26, 33 - - 36, to wind the used portion on to the roller 16 and feed a fresh length from the roller 10. On releasing the treadle 64, the shield 62 drops by gravity and the spring 81 returns the chain 80 to its original position. A spring- pressed friction coupling is provided between the gear wheel 26 and the roller 16 to allow the roller to slip as the towel roll increases in diameter. The supply of towelling may be folded in zig-zag form and withdrawn as required from the bottom. In a modification, the supply roller 106 and the feed rollers 107, 108 are mounted as shown in Fig. 7, and pressure rollers 109, 112 on arms 110, 113 are provided, while spreader arms 117 are adapted to be rotated by a rod 119 to separate the rollers 109 and 112 from the rollers 107 and 108.

Filed: 1917-06-30
Abstract: 116,940. Jackson, W. J. Mellersh-, (Seaman Waste Wood Chemical Co.). June 30, 1917. Charging and discharging; rotary furnaces; retort furnaces.- In furnaces for distilling wood &c., the material treated is utilized to seal the retort after the air contained in the charge has been expelled therefrom by mechanical action. The carbonized material is also caused to seal the retort at the discharge end. As shown in connexion with a rotary retort, the material in a finely divided state is delivered from the hopper 26 into a feed pipe in which is a reciprocating plunger 27. The charge is thus compressed in the feed pipe and in the neck of the retort. The stroke of the plunger stops short of the inner wall of the mouth of the hopper, so that air can escape through the loose charge in the hopper. At the discharge end, the material falls into a pocket 36 with a screw conveyer which delivers it to a hopper 37<a> above a reciprocating plunger in the discharge pipe 39. The retort is preferably heated by fireplaces 14, Fig. 2, the gases from which pass through a long chamber or flue 13 with numerous ports 15. The combustible gases discharged from the retorts are passed through a water seal and delivered to the fireplaces through pipes 46 within air pipes 47.

Abstract: 938,087. Measuring unevenness in rails. L. SCHENKIR, and A. KIENER. March 15, 1961, No. 9546/61. Class 105. Apparatus for measuring and recording unevenness in rail surfaces comprises resistive elements 7, 8, 9 which vary in resistance as their length is varied, mechanically connected in parallel with springs 4, 5, 6 associated with wheels 1, 2, 3 of a three-axled vehicle and connected electrically in a bridge circuit which is energized across points 10 and 11. Elements 7 and 9 form a referenee resistance value against which the variations in resistance of element 8 are compared and an output signal which is a measure of the unevenness of the rails is developed across points 12 and 13 and recorded. Elements with an electrical parameter which varies with applied tension or force may replace the elements 7, 8, 9 and with circuit modifications the arrangement can operate on an inductive (Fig. 3, not shown), capacitive or piezo.eleotric principle. In a further single wheel arrangement, Figs. 4a and 4b (not shown), the wheel deflection relative to a seismic mass is recorded and the effect of the unevennesses may be evaluated simultaneously by the use of an accelerometer which measures the acceleration imparted to the wheel and axle in a direction at right angles to the rail.
