Title: Method of and apparatus for preventing damage to cargo in cargo compartments
IPC: B63J2/08
Filed: 1937-05-19
Abstract: 501,269. Preserving and conditioning food. COLBY, M. R. May 19, 1937, No. 13993. Convention date, May 23, 1936. , [Classes 49 and 81 (i)] [Also in Groups X, XIII, and XXI] The humidity of the air in cargo compartments in ships' holds, or in warehouses, is controlled by closing the compartment and supplying air to one side and withdrawing it from the other, a proportion of dried air being added to the recirculated air. With a cargo of fruit, ethylene or carbon dioxide may be added to the recirculated air to control the ripening. A fumigant may be used in the air ducts for fumigation purposes. The ship's hull 10 is divided by water-tight bulkheads 9 into holds each having air inlet or outlet ducts 14 adjacent their sides, risers 15 leading into a common duct 16 in which is a reversible fan 17, a thermometer 19, hygrometer 20, and pressure gauge 18 being provided. Conduits 23, 24 provided with valves 25, 26 lead to the atmosphere. Air may be drawn by the fan 17 from the starboard side 30 into the duct 16 and passed via risers 15 and ducts 14 into the port side, the humidity being controlled by addition of dry air through conduit 29. Air from outside the hold passes by pipe 37, or from inside the hold by pipe 72 through a valve 36, filter 38, pump 40, and cooling or heating coils 31 to a chamber containing silica gel, alumina gel, titania gel or activated carbon 58 by which it is dried. Gilled ,pipes 62 are submerged in the drying agent and may be traversed by a cooling agent such as sea water, or may carry steam for reactivating the drying agent. An overflow conduit 57 collects sea water, condensed steam, or moisture removed from the drying agent when it is reactivated by steam heating and the passage of air to carry away the moisture through pipe 68. When air outside the hold from pipe 37 is dried and supplied to the recirculated air, the pressure in the hold is raised and entry into the hold prevented. Ethylene is supplied to the hold from a container 77, or carbon dioxide from a source 79 when in the case of fruit it is desired either to hasten or retard its ripening. The holds may be fumigated by supplying a fumigant from a container 84 through a pipe 86 to the air supply conduit 16 and fresh air is used subsequently to clear the holds.

Title: Improvements in or relating to surgical material
IPC: A61L15/46
Filed: 1932-05-17
Abstract: A surgical dressing consists of superposed webs of water-penetrable material such as gauze, one web being impregnated with an iodine-containing material capable of releasing free iodine, and another web being impregnated with a material capable of reacting in the presence of moisture with such iodine-containing material with the release of iodine.  The iodine-containing material may be an iodide, such as of one or more of the elements potassium, sodium, calcium or barium, in which case the other material is an oxidizing agent, for example, calcium or potassium iodate or periodate, potassium permanganate or ferric chloride.  An acid such as citric or tartaric acid, or an acid-reacting substance such as aluminium sulphate must also be present with the oxidizing agent.  The acid and oxidizing agent may be afforded in a single compound, for example, iodic or periodic acid, or ferric chloride.  Alternatively, an iodate or periodate such as of one or more of the elements barium, calcium or potassium may be employed as the iodine-containing substance, in which case the iodine-releasing substance is a reducing agent, for example, sodium, potassium or calcium iodide, or sodium or potassium thiosulphate.  An acid such as has been specified must also be present.  Separate areas of the gauze are impregnated with solutions of the several materials, dried and folded.  The impregnated layers may be in immediate contact, or they may be separated by an unimpregnated layer of gauze or other water-penetrable material.

Title: Improvements in or relating to creep testing machines
Inventor: THORLEY THOMAS
IPC: G01N3/08
Filed: 1949-05-26
Abstract: 670,106. Testing physical qualities of materials. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. May 9, 1950 [May 26, 1949], No. 14159/49. Class 106 (ii). The pull-rod of a creep-testing machine comprises two portions connected by means operable to permit the portions to move rapidly relative to each other so as to produce a sudden increase in the effective length of the pull-rod. The specimen (not shown), which is maintained at a desired temperature by an electric furnace, is tensioned by a pull-rod connected by a lever system to a weigh-beam carrying a travelling- weight. If the furnace fails, the contraction of the speciment raises the end of the weigh-beam 6 and a trip-lever 21 is rocked. An extension 23 of this lever rocks a catch 20 to release a pivoted stop-arm 19 for a plunger 17. The plunger is engaged by a roller 15 held between pins or rollers 13, 14, mounted respectively in a forked member 11 and a lug 12 secured to the two parts of the pull-rod, and held slightly out of alignment therewith by a stop 16. When the plunger 17 is freed, the pins 13, 14, which are urged together by the tensioning load, force the roller 15 from between them and move into contact with one another, thus increasing the length of the pull-rod to prevent damage to the apparatus by the weigh-beam engaging its stop. In a different arrangement, the catch 20 is operated by a solenoid associated with a switch operated by the weigh - beam. The solenoid may alternatively be connected in the furnace circuit and arranged so that, if the supply fails, the catch 20 is operated. The stop 16 may be spring-loaded to increase the speed of operation of the safety-device.

Title: Improved torsion spring
IPC: B60G11/23
Filed: 1937-05-22
Abstract: 491,264. Indiarubber springs ; spring frames for cycles. VOIGT, C. A. May 22, 1937, No. 14266. Convention date, May 23, 1936. [Class 108 (iii)] [Also in Group XXXI] A torsion spring element comprises a rubber member which is adapted to be stressed in shear by the relative movement of two pivoted members and which is bonded to the pivoted members, or to metal parts connected to these members, and is only a portion of a disc or ring. The rubber element may be constituted by a block of rubber positioned away from the pivotal axis, and such that its greatest circumferential dimension in a plane perpendicular to the pivotal axis subtends a relatively small angle at the pivotal axis. In the construction shown in Fig. 1, an arm 2 carrying a wheel 1 is secured to an axle 3 mounted in a frame member 4 by a journal bearing 5 and a roller or knife-edge bearing 6. Two blocks 9 of rubber are bonded to plates 8 secured to the frame 4 and to plates 7 non-rotatably secured to the axle 3. The plates 7 are inclined outwardly relative to the plates 8 in order that the cross-sectional area of the rubber blocks may increase with distance from the pivotal axis. Alternatively or additionally the blocks 9 may be formed of rubber of different compositions and such that its elasticity progressively increases with respect to distance from the axle 3. In a modified construction, Fig. 3, the arm 2 is rotatably mounted on a bolt 19 and the rubber blocks are secured to extension 4 of the frame and to plates 20 secured to the arm. The arm 2 may be extended beyond the bolt 19 and attached to further rubber blocks. In a further modification the bolt 19 is rotatable in the frame member 4 and is formed with a rigid extension acting as a torsion bar. Fig. 6 shows an arrangement applied to a cycle or motor cycle in which blocks 16 of rubber are secured to plates 20 attached to the rear fork 14 and to plates 21 attached to a rearward extension 17 of the frame 18 mounted on a transverse pin 15. The plates 20, 21 are inclined towards each other so that the rubber is also compressed by relative movement between the fork 14 and frame extension 17. Where necessary a number of blocks may be arranged in line parallel to the pivotal axis.

Title: Improvements in electric furnaces
IPC: H05B3/62
Filed: 1922-05-22
Abstract: 198,898. Wild, L. W., and Barfield, E. P. May 22, 1922. Resistance furnaces.-In an electric furnace a having heating elements consisting of rods, bars or plates of carborundum, b, the electrical connection to the heating elements is made by carbon rods c pressed against the carborundum by the action of gravity or springs so that the contact is automatically maintained as the carbons are consumed. The elements are made by fritting crushed carborundum crystals without any bonding material. Such elements are stated to have a specific resistance of 0.8 ohms per centimetre cube at 1400‹ C. In modifications, the heating element is situated in the roof of the furnace chamber and comprises a single plate or separate bars on either side of the chamber. Starting up is effected by applying an initial voltage many times greater than the normal, the supply being obtained from a transformer having suitable tappings. If a number of heaters are used starting up may be effected by first connecting them in parallel, then parallel series and finally full series. Alternatively the heating elements may be initially heated by a rod wound with a nickel chrome wire, or by the flame from a gas or liquid fuel burner. Stability of current and temperature is obtained by including a ballast resistance or choking coil and a regulating resistance in series with one or each of the heating elements. The ballast resistance may take the form of a wound muffle furnace used for preheating the work.
