Title: Variable delivery gear pumps
IPC: F04C14/22
Filed: 1960-10-03
Abstract: 968,998. Gear pumps. W. REINERS, and G. WIGGERMANN, [trading as REINERS & WIGGERMANN, GETRIEBE-UND MASCHINENBAU]. Oct. 3, 1960, No. 33824/60. Heading F1F. A housing for a gearwheel pump comprising three intermeshing gear wheels having their axes substantially in a common plane and the intermediate wheel adjustable with respect to the outer wheels to vary pump delivery, comprises a two-part housing constructed contiguously around the outer two gear wheels so that only the intermediate wheel is surrounded by an annular hollow space guiding the idle streams of fluid flowing tangentially and in opposite directions around this wheel. As shown in Figs. 1 and 2, the housing parts 1a, 1b are equally recessed so that the partition plane lies substantially in the mid-plane of gear wheels 2, 3, 4 to produce symmetrical loading on the two housing halves and hence lighter construction of the housing and its fastenings. The wheel 2 is keyed to a driving shaft 6, the wheel 4 freely mounted on a distance bolt 17 and the wheel 3 mounted on an eccentric shaft 9 through which passes with clearance a fixing bolt 8 screwed into a cover disc 10 and securing a thrust-cap 11. The cap 11 is held against rotation by a pin 13 and groove 12 and formed with a recess 16 limiting the movement of a lever 15 adjusting the position of the wheel 3 within a range in which the axial distance between it and the driven wheel 2 is always equal to or greater than the distance between it and the outer free wheel 4. The housing parts are identical so that the lever 15 and the projecting end of the driving shaft 6 may be located on the most convenient side of the housing. Fastening bolts 22, Fig. 3, may be reduced in number from 11 to 8 by fitting them closely adjacent the gear wheels, with two of the bolts securing elbow bends 25 over the supply and discharge bores 7a, 7b. Alternatively the housing parts 1a, 1b may have unequal recesses, so that two shallow recessed parts or two deep recessed parts or one shallow and one deep recessed parts may be connected together to accommodate gear wheels of three different widths without increasing the number of patterns required in the manufacture of the housing. A relief valve housing 24, Fig. 7, may be connected to the housing by the same bolts 22 which connect the elbows 25 to the housing. The width of the housing adjacent the intermediate wheel may be reduced by the machining of annular depressions 21, Fig. 4, in the housing halves and these depressions in association with arcuate depressions 28 surrounding the wheels 2, 4 and extending for an angle # beyond the central axis X result in a reduction in frictional losses and in the heating of the pumped medium. Shaping of the depressions 21 in the region of the intermeshing points as shown in Fig. 4, together with the tooth gaps provides more gentle compression and expansion of the pumped medium with a consequent reduction in noise. Radial grooves 32 permit positive lubrication of the gear-wheels.

Abstract: 1370865 Inverting apparatus for induction heating MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 25 July 1972 [10 April 1972 (6)] 34778/72 Headings H2H and H2F An induction heating device such as a cooking apparatus comprises an inverter fed from an A.C. source by way of a full wave rectifier, the heating device being energized by the' output from the inverter, the inverter including a gatecontrolled semi-conductor device and being provided with protective devices to prevent damage thereto which would occur due to current surges at switch-on and to heavy overload currents. Induction heating apparatus comprises a heating coil 35 which co-operates with a cooking utensil 37, the heating coil 35 being energized by an inverter 27 which comprises an inductor 34 and a capacitor 33 forming a resonant circuit which is set into resonance by the firing of a thyristor 29 paralleled by a diode 30 oppositely connected. The inverter 27 is supplied from an A.C. source 20 by way of a main switch 22 and a full wave rectifier 21. Firing of the thyristor 29 is controlled by a pulse generator 38 which generates a train of pulses conditioned by a feed back signal derived by a detector 42 representing the output frequency of the inverter whereby the output frequency of the inverter can be maintained sufficiently constant whatever the output voltage of the rectifier 21. In order to protect the thyristor 29 from a heavy instantaneous current when the inverter is switched on such switching on is arranged to take place when the output voltage of the rectifier 21 is substantially zero. For this purpose a zero voltage switching device 40 is provided which includes a thyristor serially connected in the negative output line 26 of the rectifier. A delay circuit 41 is provided so as to ensure that no pulses are delivered by the pulse generator 38 until the voltage thereacross reaches a predetermined level. Should the current supplied to the load 37 tend to reach an excessive level, a circuit 43 is provided to prevent such an excess current. In other embodiments excessive currents are reduced by using a series connected resistor or a variable inductor in the circuit of the heating coil 35 and heavy initial current flow may be prevented by using a series resistor in the output of the rectifier 21 which resistor is short-circuited by means of a relay during normal operation. The zero-volt switching device 40 may be made responsive to a switch thermally responsive to the heat generated in the load 37. The system is furthermore designed so that the output frequency of the inverter 27 is dependent upon the type of utensil being used.
