Title: Fluid Coupling
Inventor: SUTARUK ALEX
IPC: F16D35/02
Filed: 1968-07-02
Abstract: 1,195,794. Fluid couplings. EATON YALE & TOWNE Inc. 2 July, 1968 [11 Aug., 1967], No. 31616/68. Heading F2C. In a fluid coupling comprising relatively rotatable coupling members, the primary support between the coupling members is provided by a fluid shear medium between opposed shear surfaces of the coupling members. In Fig. 1, a coupling 10 for driving a fan 12 of a vehicle motor comprises an input coupling member 14 having a radially extending portion 20 which rotates within a working chamber 18 defined by an output coupling member 16. There is clearance between the hub 22 of the coupling member 14 and openings 38, 40 in the coupling member 16 but seals 42, 44 prevent leakage of a fluid shear medium, e.g. silicone fluid, which flows into the chamber 18 from a reservoir 51. The primary bearing support for the output coupling member 16 is the shear fluid between the members 14, 16 whose adjacent shear surfaces 46, 48 do not normally touch. When the coupling is operated, centrifugal pressure acting on the fluid in the annular reservoir 51 causes the fluid to flow via openings 56 into the chamber 18 and particularly into a shear space 50 containing the peripheral portion 20a of the coupling member 14. Slots 57 (Fig. 7) in the coupling member 16 promote a hydrodynamic film between portions of the shear surfaces 46, 48 to support a thrust load. By controlling the return of fluid from the chamber 18 to reservoir 51, by means of a bi-metal valve (60, Fig. 3, not shown), the drive to the fan 12 may be varied in dependance on temperature. The hub 22 is a press fit on a water pump shaft 26, the fitting being accomplished by a threaded member 30 and removal by a further threaded member (33, Fig. 2, not shown). Hardened steel or iron is specified for the coupling member 14 and aluminium for the member 16. Cooling fins 68 are provided.

[Also in Group XXVIII] Filter paper (or other) sheet 6, Fig. 2, is corrugated between rollers 1, 2 and has applied to it adhesive 5 before it is stuck to a plain filter paper (or other) sheet 7. A narrow fillet of sealing compound 9 is extruded at 10 near one edge of the sheet 7 (and optionally near the other edge by like means) so that at least one end of the " confined " corrugations is closed. Subsequently, there is applied to the assembly a fillet of an elastomeric sealing compound 17, Fig. 3, in the " open " corrugations and not near the location of the sealing compound 9, the fillet being covered by non-adherent tape 19 before coiling at 15. When the coil is unwound and tape 19 removed, the edges are trimmed (see Fig. 6). Where two fillets 9 are provided, as in Fig. 6, the assembly may be slit lengthwise as shown. One half may then be cut into lengths which are stacked alternately to form the element of Fig. 12. Alternatively, a length may be coiled into cylindrical formation for axial flow of the liquid. The assembly of Fig. 6 need not be slit lengthwise; instead it may be coiled to form the element of Fig. 11, wherein two stages of filtration in series are provided in a single element, as shown by the arrows. Fibre glass mat or cloth may be used instead of paper. Specification 703,823 is referred to.

Abstract: 1,187,068. Broiler. P. M. PAPPAS. 11 July, 1967, No. 31883/67. Heading A4D. [Also in Division F4] A broiler comprises a casing, a firebox within the casing and a sectional reversible cooking grid 4, the grid having multiple U-shaped parallel channels 4A with openings 6 into the firebox between them, the channels being fixed so as to be inclined towards a fat-collecting well 9 set below the edges of the channels, and such that when the grid is inverted a supporting rib 4B is exposed on the top portion of each inverted U-channel and also alternate openings between the channels into the firebox. By this means the U-channels, when uppermost as on the right-hand side of the broiler in the Fig., receive most of the liquified fat from the food cooking on the grid, the lesser part of the fat dropping into the firebox. When the grid is inverted as on the left-hand side in the Fig., all of the liquified fat drops into the firebox. The broiler may also have a vertical rear exhaust flue pipe 3 which allows exhaust heat to escape from the firebox, namely the grate 16, and the excess fat may be drained from the well into a grease collecting pan 13.
