Title: Method and positive-displacement engine for converting one form  of energy into another form of energy
IPC: H02K44/00
Filed: 1973-01-19
Abstract: 1408236 Rotary positive-displacement machine BATTELLE DEVELOPMENT CORP 19 Jan 1973 [31 Jan 1972] 2928/73 Heading F1F In a heat engine spherical free-pistons 16 are propelled anti-clockwise along an endless passageway 12 by an expanding hot gas e.g. air, which is introduced, either initially or continually, in a compressed state through a tube 18, heated by a coil 20 and either ejected (after expansion) through an outlet 22 or cooled in that region, useful energy being produced by the pistons in the form of electric pulses induced in a coil 40 of a linear generator 37 and/or air inducted through an inlet 24 and compressed into a vessel 42. Reverse piston motion is prevented by ratchet-controlled wheels 26, 28. The tube 18 may be fed with air by the vessel 42. The pistons may be other than spherical in shape. In a second embodiment, Fig. 2 (not shown), differs in that the working fluid is heated externally of the passageway in a heat exchanger (70) and a latch (66) replaces the wheels 26, 28. The engine may be modified to operate on the Brayton, Rankine, Otto or Diesel cycle, Figs. 3 to 5 (not shown). In another embodiment, Fig. 6 (not shown), the pistons are propelled by a travelling magnetic wave accelerator (88) to compress a gas in the passageway and induce pulses in a linear generator (90). In yet another embodiment, Fig. 7 (not shown), the pistons are again propelled by an expanding gas that is heated externally of the passageway in a heat exchanger (96) but drive a power-output shaft (100) through permanent magnets (104) fixed thereto. In a further embodiment, Fig. 8, the pistons 117 are driven clockwise along an oblongo-circular passageway 111 by expanding air that is heated in a heat exchanger 126 and enters the passageway through an inlet 123, a power-output shaft 122 being rotated by the pistons striking blades 121 extending through a slot 120. Air compressed by the pistons leaving said blades passes into the heat exchanger through a check valve 127. Blades 115 driven by a shaft 113, which may be coupled to the shaft 122, extend through a slot 116 return the pistons to the region of the inlet 123. Leakage from the slot 116 may be prevented by a housing 128. This embodiment is said to operate on a modified Brayton cycle, Fig. 10 (not shown).

Title: Automatically variable speed transmission
IPC: F16H33/16
Filed: 1935-01-30
Abstract: 435,299. Variable - speed gearing. MUYNCH, A. DE, 20, Rue V. de Saedeleer, Alost, Belgium. Jan. 30, 1935, No. 3055. [Class 80 (ii)] An automatically varying gear or torque converter suitable for motor-vehicles comprises hollow planet wheels 5, Fig. 1, carried by a flywheel 2 fast on a driving-shaft 1 and meshing with a sun gear 6 fast on a driven shaft 7. Each planet wheel 5 carries blades 10, Fig. 2, projecting inwardly from the outer cylindrical wall so as to form cells 11 for mercury. The torque transmission is governed by a continuous and progressive backward flow of mercury from one cell to another without the said mercury being carried by the blades 10 as far inwards as the inside of a circle x described by the axes 4 of the wheels 5 about the main axis. The wheel 5 in Fig. 2 is being turned to the right as shown by the arrow by the load resistance, and masses of mercury 12 are carried by the blades 10 downwards or inwards on the right side. As a cell of mercury approaches the circle x, the centrifugal resistance of the mercury opposes the inward turning of the wheel 5 and so produces elastic driving torque on the gear 6. If the mercury were carried right round with the wheel 5, vibration would be set up. To induce steadiness in the drive, the arrangement is such that the mercury pours back over the blades 10 before passing the circle x. In a form shown in Figs. 3 and 4, the blades 13 are adapted to yield resiliently so that the cells can contain and carry less mercury as the speed increases. Each blade 13 is inclined forwardly inwards, pivots about its outer edge 15, and has a tooth 16 at its inner edge engaging between teeth 17 on a barrel 19 connected to the body of the wheel by a spring 20. The effect is that there is more mercury in the outmost cell 12a where the centrifugal force is greatest. If this gear device is used for braking the vehicle by the engine, the relatively reversed angularity of the blades has the effect of spilling the mercury. To prevent this, and allow such braking, supports 22, Fig. 3, are provided at the backs of the blades.
