Filed: 1927-02-07
Abstract: 267,097. Hawkins, C. L. March 3, 1926, [Convention date]. Fixed-chamber apparatus, varying quantity measured in. - An apparatus for retailing measured volumes of petrol, benzine, lubricating oil, and like liquids comprises an overflow pipe with adjusting-means, designed to facilitate the sale of various quantities, interlocked with the delivery valve. Fig. 1 shows an aparatus, without its casing, comprises a base 10 supporting a framing 11 and head 12, above which is a glass measuring-vessel, not shown, and a cap 13. Inside the glass vessel is a gang of knife blades 16, set at various levels corresponding to the various volumes, for instance, gallons, to be sold. A semi-rotary or plunger pump 17 delivers fuel through a pipe 20 to the measuring-vessel the liquid filling the vessel to the level of an adjustable overflow pipe 31, raised to its upper limit. To retail any desired quantity, a spindle 63 is rotated until the word " Full " is shown on the dial 65 at each end of it. This movement rotates also a vertical spindle 67 with quantity stops 70, all of which are thus moved out of the path of a striker 72 on a rack 56, which, together with the pipe 31, is raised by the handle 61. In the top position the tappet rod 30 on the top of the tube 31 strikes a lever 29, compressing the spring 27 and forcing down the slide valve 23. The pump 17 is then operated to pump liquid up the pipe 20 into the measuring-chamber, which it enters through the ports 21 the annulus 25, and ports 26; excess liquid flows back through the tubes 31, 35. and the container so filled to its limit, say six gallons. To retail say two gallons, the operator rotates the spindle 63 to the twogallon indications on the dials 65, bringing the two gallon quantity stop 70 into the path of the striker 72 as the rack 56 is moved down; liquid in excess of two gallons then runs back to the tank. The delivery valve 41, Fig. 3, is now opened by the lever mechanism 42 - - 45, which also, by means of the mechanism 47 - . 54, shoots the bolt 55 into one of the holes 57 in the rack 56, so that the rack is locked while the delivery valve is open. The valve 23, Fig. 2, is closed as soon as the slide tube 31 is depressed, so that liquid cannot be pumped into the measuring-chamber while the delivery valve is open. The tube 31 slides through a gland 34, and is adjusted by a rod 38 passing through a stuffing-box 37. Indicating and metering devices are fitted.

Title: Electric fan
IPC: H02P25/14
Filed: 1974-01-25
Abstract: 1463162 Control of AC motors PETER WENTIEN TSAY 25 Jan 1974 03643/74 Heading H2J A fan is driven by a split-phase motor having main and auxiliary windings M, A and a starting capacitor C, the windings being controlled by a Triac TR whose firing angle is determined by a trigger signal generator 60 in response to the setting of a manually-adjustable control resistor VR1 corresponding to a desired motor speed, a control network 30 also being provided whereby, when it is energized by closure of a switch S3, a capacitor C6 respectively charges and discharges during successive half cycles of the A.C. supply to the motor, so that the voltage across the resistor VR1 is correspondingly varied to cyclically increase and decrease the speed of the motor. During alternate half cycles the capacitor C6 is charged through diode D2 from the secondary winding of a transformer T1, also supplying a low voltage to the generator 60 through a voltage compensation means 20 which prevents variations of the voltage of the A.C. supply causing changes of motor speed. The discharge of capacitor C6 may be varied by an adjustable resistor VR2 gauged to a switch S2 which opens when VR2 has been reduced to zero, so that a high value resistor R11 is inserted in the discharge circuit to reduce to a minimum the speed variation produced by network 30. Further desired speed variations may be produced by closure of a switch S7 to connect the output of a signal generator 90 to the resistor VR1, the output being an irregular wave obtained by combining the outputs of two different low frequency relaxation oscillators R20, C7, DIAC 1 and R21, C8, DIAC 2, whereby the speed variations cause the fan to provide an air flow imitative of a natural wind. Closure of a switch S6 energizes a reversing circuit 80 comprising a Schmitt trigger Q5, Q6 and a relay coil R whereby, with the motor speed gradually reducing due to the action of network 30, the Schmitt trigger operates at a predetermined value to energize coil R whose contacts S11-S14 change over to reverse the direction of motor rotation. Features of the generator 60 are provision of (1) a resistor R8 and switch S1 which is opened to reduce the speed to zero and closed to obtain a certain minimum value; (2) circuit C4, R5 to ensure reliable starting of the motor and so prevent overcurrent during this period, and (3) a resistor R6 inserted by closure of a contact S5 of relay R to produce an increased motor speed after it has been reversed by operation of the circuit 80. The motor may be replaced by one of the commutator or shaded pole type. A basic circuit comprising members 10, 30, 50, 60, 70. Fig. 1 (not shown), may be used with various combinations of members 40, 80, 90, Figs. 2 to 5 (not shown).

BAUKNECHT, [trading as GOTTLOB BAUKNECHT ELEKTROMOTORENBAU]. 26 Jan., 1968 [14 Nov., 1967], No. 4155/68. Heading F4H. In a refrigerator having a freezing compartment and a cooling compartment cooled by two series connected evaporators forming part of a compression-condensation refrigeration cycle whose expansion device is a capillary tube, the capillary tube is arranged in heat exchange relationship with the evaporator in the cooling compartment. The arrangement ensures that the cooling compartment is operated at a temperature above that of the freezing compartment, and provides automatic defrosting of the evaporator in the cooling compartment when the compressor is switched off by virtue of the warm refrigerant in the capillary tube at that time. As illustrated, the compressor 1 supplies refrigerant through the condenser 2 to the capillary tube 3 which is in contact with part of the cooling evaporator 7 and which feeds the freezing evaporator 4. A thermostat (not shown) controls the compressor, and whenever the latter is switched off, the evaporator 7 is automatically defrosted. Refrigerant vapour thus formed is recondensed and stored in an accumulator 6 in the freezing compartment pending re-energization of the compressor. In another embodiment, Fig. 2 (not shown), the capillary tube is in heat exchange contact with the whole of the cooling evaporator and feeds that evaporator. The temperature stability of the freezer compartment may be improved by placing a liquid filled flexible container in contact with the freezer evaporator to act as a cold store, Figs. 3 and 4 (not shown). The evaporators may be of the plate type and the capillary tube may be soldered to the outer wall of the cooling evaporator, Fig. 5 (not shown), or may be located within a duct of the evaporator, Fig. 6 (not shown). The evaporators may be located in the compartments or may be in separate chambers, cold being conducted to the compartment through the chamber walls.
