Abstract: 222,142. Platen-Munters Refrigerating System Aktiebolag, (Assignees of Wessblad, K. A.). Sept. 22, 1923, [Convention date]. Refrigerating, absorption processes for. - The - condenser and absorber of the system are cooled by the agency of a volatile medium circulating in an independently closed cycle and undergoing alternate vaporization and condensation substantially at the same pressure, the medium being cooled in a condenser exposed to the air. The process is described as applied to a continuouscycle absorption apparatus wherein a neutral gaseous medium circulates between the absorber C and the evaporator B to equalize the pressure throughout the system, a circulation of strong liquor between the absorber and the generator A being effected by a coiled rising pipe M in the generator, as described in Specification 202,650. The volatile exchange medium is contained in a circuit including a coil N exposed to cooling air and constituting a condenser, and a vessel 0 enclosing the condenser D and absorber C of the refrigerating apparatus and ' constituting an evaporator. The volatile medium may be discharged from the condenser N through a pipe rising nearly to the top of the vessel 0 so as to maintain the condenser and absorber vessels D, C constantly submerged in the liquid medium. In a modification, the medium may circulate through a coil passing through a vessel such as the vessel 0 containing brine or other intermediate heat-exchanging fluid. In addition to the circuit for cooling the condenser and absorber, a circuit containing a similar medium may be used to abstract heat from the evaporator of the refrigerating apparatus by condensation, the medium serving by its evaporation elsewhere to cool other substances. The cooling system may be applied to other types of refrigerating apparatus. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-Several circuits may be used for one refrigerating apparatus, the condensers and evaporators of such circuits being disposed at different convenient points and arranged in parallel with respect to the parts exchanging heat with the condenser and evaporator of the refrigerating apparatus. This subject-matter does not appear in the Specification as accepted.

Title: An improved method of and apparatus for determining the height of the centre of gravity of ships
IPC: B63B39/12
Filed: 1922-08-16
Abstract: 207,233. Wall, A. T., and Maas, N. N. Aug. 16, 1922. Stability, determining.- In apparatus for determining the centre of gravity of a ship from a consideration of the head given by a displacing force, an inclinometer 1 arranged athwartship is pivoted at 2 and carries a pivoted spirit level 17 the position of which can be adjusted by means of the screw stud 19. The free end 9 of the inclinometer works across a scale 15 appropriate to the displacement of the ship. In operation, the ship is heeled by means of a weight and the spirit level and the reading of the pointer 9 are both zeroized. The weight is then moved athwart ship to heel the ship in the opposite direction and the position of the inclinometer is adjusted by means of the micrometer screw 14 until the spirit level again occupies a central position. The reading of the pointer on the scale 15 then gives the height of the centre of gravity of the ship. In modifications, the spirit level is replaced by a plumb bob and a series of scales such as 15 appropriate to various displacements of the ship are arranged on the periphery of a drum, the appropriate scale being turned into alignment with the pointer 9.

Class 38(5) A switchgear structure comprises a casing, e.g. of an isolator switch, with a lid which carries a switch operating member having a part working in a gate which prevents removal or replacement of the lid except when the operating member is in its OFF position, said lid having a switch locking detent adapted to be rendered inoperative by a lug on the lid of an associated switch, e.g. a contactor. The isolator lid 16 carries a slidable operating member 18 having a portion 21 engaging the switch mechanism 24 and a tongue 22 which can only pass through a gate 23 when the member 18 is OFF. A spring detent 25 on the lid has a portion 26 which co-operates with an arm 20 on member 18 to prevent movement of the latter to the ON position except when the detent is pressed back by a lug 27 on the contactor lid 12, the lug 27 passing through a slot 15 in the lid 16 when lid 12 is in position. When the member 18 is in the ON position, the arm 20 'overlies the lug 27 to prevent removal of the contactor lid 12.

Abstract: 656,581. Suction cleaners. KNIGHT, H. G. W., and BURGESS, P. Aug. 25, 1948, No. 22432. [Class 8(i)] [Also in Group XXVI] In a suction cleaner of the kind having a heater 26 within the suction nozzle 10 and reciprocated by a vacuum motor, the nozzle 10 is in permanent communication with the source of suction and with a space on one side of a member, e.g. a piston 19 reciprocable in chamber 10 and having one or more ports 21 controlled by a valve 24 reciprocably mounted thereon and connected to the heating member 26, the movement of the valve being limited in one direction, e.g. downwards by the heater 26 contacting the surface being cleaned, and in the other direction by a part of the valve 24 engaging a fixed abutment 29 whereby continued movement of the piston 19 downwards after the valve 24 is arrested causes said ports 21 to be opened, and continuous movement upwards causes the ports 21 to be closed. Downward movement of the piston 19 by suction against a spring 36 is limited by abutment of the piston boss 23 against a cushion 37 of a stop 27 secured to a stem 22 of the valve 24. In a modification the heater stem slides in a hollow valve stem against a spring and the fixed abutment comprises an adjustable screw. The nozzle may be used as a massage apparatus. The Provisional Specification describes also a vacuum motor comprising a vertical cylinder having a closed bottom and an upper end open to suction, and a downwardly directed spring-loaded piston having ports in the crown controlled by a valve on the heater stem which extends through both the crown and the cylinder bottom. Specification 656,582, [Group XXVI], is referred to.
