Abstract: 513,231. Liquid-fuel supply &c. ASIATIC PETROLEUM CO., Ltd., and RICHARDSON, A. W. April 2, 1938, No. 10171. [Class 75 (i)] [Also in Group XIII] Apparatus for giving a controlled quantity of heat to a unit such as a refrigerator, incubator, brooder battery, or greenhouse heater, comprises one or more trays 1 which can be slid, e.g., in guides 2, into the unit and is provided with wells 3, 4 which receive liquid fuel from tanks 5, 6 carried by the tray or trays, the wells being connected to a common delivery-line 8, 12 also carried by the tray or trays, a thermostaticallycontrolled valve 9, and one or more burner bowls 11 which receive burners 13 of the perforated drum type. The unit carries a casing 14 to house the burner or burners when in position. This casing has at the front a hinged flap operated by a rod and handle 17, to allow the passage of the burner when the tray is slid out of position. The flap may be arranged to open automatically when the tray is withdrawn, and to remain open until it has been reinserted. The burner bowl 11 is in the form of an annular groove. The various parts may be mounted on two or more trays. The pipe lines are then flexible. Specifications 488,494 and 511,211, [both in Group XXIX], are referred to.

Title: Improvements in and relating to ultra high frequency inductors
IPC: H01F21/06
Filed: 1944-05-25
Abstract: 609,708. Inductances. POLYDOROFF, W. J. May 25, 1944, No. 10174. Convention date, May 22, 1942. [Class 38 (ii)] A variable inductance for increasing the tuning range at high frequencies, comprises a movable ferro-magnetic core 2 coaxial with a coil divided into a number of sections connected in parallel. For frequencies of the order of 100 megacycles, only a very small value of inductance is needed, and a suitable inductor would normally have few widely-spaced turns giving a small tuning range. To obviate this, a coil 3 is divided into two parts connected in parallel so that many more turns may be employed. In another modification, the coil comprises four sections. In all cases the sections are connected in aiding relation, have equal inductance and are arranged symmetrically. Core 2 is of powdered magnetic material such as magnetite or of iron alloyed with silicon or antimony. Fig. 6 shows a coil with a ribbon type of winding 3 divided into two sections, the core 2 being formed of a number of discs with air spaces for cooling. The Specification as open to inspection under Sect. 91 comprises also a similar inductance in which the turns are formed by cutting slots in a single conducting strip. This subject-matter does not appear in the Specification as accepted.

Filed: 1937-04-14
Abstract: 478,165. Strapping and wiring packages. KIND, O. April 14, 1937, No. 10659. Convention date, March 20. [Class 45] A tensioning device is mounted on a block 8 on the base plate 1, having two longitudinally displaceable slides 10, 11 in guides 22, operable to move towards and away from each other by crank-pins 16, 17 engaging pin holes 14, 15 in their extensions 12, 13. The crank-pins are on a plate 18 oscillatable by a hand lever 21. Each slide carries a pawl 28 obliquely disposed at the same inclination to co-operate with a plate 27 projecting from the lower part of the slide. Each pawl is associated with a lifting arm 31 so shaped that the introduction of the wire or strapping lifts it and the pawl with it so that the wire can enter between the pawl and the plate 27. A spring 34 biasses the pawl and arm towards the plate. In use, the end 35 of the wire is held in a clamping eccentric 5, Fig. 6, and the wire 36 is taken round the package, the end 37 to be tensioned being placed beneath the pawls 28. When the lever 21 is swung in a clockwise direction, the pawls approach each other to the positions shown in broken lines. During this movement, the lefthand pawl and plate apply tension and the righthand pawl slides over the wire. Upon the movement of the lever being reversed, the pawls move apart and the right-hand one applies the tension.
