Title: Fuel induction systems for internal combustion engines
IPC: F02M23/03
Filed: 1974-06-19
Abstract: 1462127 Heating I C engine charge V M EVERETT 19 June 1974 [20 June 1973] 27082/74 Heading F1B A fuel vaporizing device comprises means to rotate the fuel in a swirl in order to cause unevaporated fuel droplets to impinge upon a heat exchange element 28 where they are vaporized, the fuel vapour then being carried in the swirl to a diffuser 36 after which it is delivered to an internal combustion engine via an inlet manifold. The fuel, delivered via a carburetter (not shown) initially passes through ports 19 into an annular chamber 23 formed between the inner surface of housing 16 and the outer surface of the diffuser 36. Vanes 58 integral with the diffuser 36 impart circular motion to the fuel, this motion being enhanced by the tangential injection of exhaust gases and air into the annular chamber via injectors 62, 60 respectively, which are throttle controlled. At low engine speeds, injectors 62 are closed and air is pumped into the annular chamber by injectors 60; as the engine speed increases, injectors 60 close and  injectors 62 open thereby permitting exhaust gases to enter the chamber. Element 28 is heated by exhaust gases transported from the cylinder head via ports 92 and returned to the exhaust system through a pipe 114, the flow of gases being governed by a butterfly valve controlled by a thermostat coil 136. The fuel vapour is directed by element 28 into the diffuser 36 subsequent to which it enters inlet manifold pipes (52, 54), Fig. 1 (not shown), communicating with the interior of the diffuser. A pressure relief valve (138) is incorporated in order to protect the device from engine backfires.

Title: Improvements in vacuum steam heating systems
IPC: F24D1/00
Filed: 1935-10-01
Abstract: 465,204. Valves. LAVERGNE, J. Oct. 1, 1935, No. 27107. [Class 135] [Also in Groups XIII and XII] In a vacuum steam heating system, the steam main 3 from the boiler is provided with a double-beat vacuum regulator 62, 63, connected to a diaphragm 11. A passage 16 allows a certain flow when the valve is closed. The diaphragm 11 is connected to a lever 26 pivoted at 27, and having a slot 29 to receive a pin 30 supporting a weight 31. The pin 30 is connected by a rod 39 to a lever 40 pivoted at 41. A weighted extension 45 of the lever 40 is connected by a link 47 to a pin 37 supporting a weight 38 associated with a slotted lever 33. The latter is connected to a diaphragm 19 subjected through pipe 21 to the pressure created by a vacuum pump on the return side of the heating system. The lever 33 is connected by a rod 48 to a switch 49 controlling the driving motor of the vacuum pump, so that the pump is stopped when the vacuum is sufficient. At the same time, the vacuum in the system raises the diaphragm 11 and opens valve 62, 63, so that the quantity of steam admitted is proportional to the vacuum. The system of levers and counterweights is so designed that the difference in absolute pressure on the diaphragms 11, 19 is equal to the losses in the pipe lines, valves, &c. Temperature regulation is effected by a saturated vapour thermometer 58 which regulates a leak valve in the pipe 55 and so regulates the pressure of water from a pipe 51, acting on diaphragm 53. Movements of diaphragm 53 are transmitted to lever 40 and thus to the system of counterweights and rods. The desired temperature may be set by a pointer 100. The regulation may also be effected by setting the lever 40 manually. In a modification, Fig. 3 (not shown), the valve 62, 63 is omitted and the air supply and draught of the boiler are controlled by movements of the lever 26. Fig. 4 shows a radiator admission valve. The valve stem 80 is provided with an operating handle 83, or alternatively, with a detachable operating key, and a spring 86 ensures good contact between a conical shoulder 82 and a cap 78 to prevent leakage. The closure member, Fig. 8, comprises a cylindrical part A whose dimensions are such as to ensure the desired resistance to flow, a part B of square section, a part C threaded into the part 81 of the stem, and a closure surface D. The part B fits into a corresponding square recess in a sleeve 88. The dimensions of the part A may vary in different parts of the heating circuit.

Title: Shift devices for operating multiple gears of motor cycles
IPC: B62M25/04
Filed: 1954-09-21
Abstract: 786,426. Control lever mechanism. FICHTEL & SACHS AKT.-GES. Sept. 21, 1954 [Oct. 7, 1953], No. 27282/54. Class 136(1) In a shift device for controlling the selector means of a variable speed gear for motor cycles the gear 5<SP>1</SP> is returned into the normal position after each gear change by means comprising a double acting spring 27. The lever 5<SP>1</SP> and a shift gate 4<SP>1</SP> are pivotally mounted on a bolt 151 in a housing 3<SP>1</SP> which is mounted on a handle-bar stem 1<SP>1</SP>. The bolt 15<SP>1</SP> also serves as a pivot point for the spring 27, the ends of which. in the centre position of this lever, abut against opposite ends of a stop 28 fixed in the housing. On rocking the lever in either direction, one end of the spring is deflected, by a bolt 29 on the lever 5 and the other end remains against the stop 28. A pawl 8<SP>1</SP> is provided which is urged by a spring 9<SP>1</SP> into engagement with the tooth steps 111, 11a<SP>1</SP>, 11b<SP>1</SP> on the shift gate 4<SP>1</SP>. A flexible cable 10<SP>1</SP> is secured in the shift gate 4<SP>1</SP> by a stud 31. When the pawl 8<SP>1</SP> is engaged in the top tooth step 11<SP>1</SP> an abutment 30 on the shift gate 4<SP>1</SP> lies against a bearing surface 32 of the lever 5<SP>1</SP> and an indicator 12<SP>1</SP> for indicating the gear is situated in the extreme left hand position. When the lever 5<SP>1</SP> is moved downwardly, as shown in Fig. 2, the shift gate 4<SP>1</SP> is rocked by the abutment 30 so that the pawl 8<SP>1</SP> will enter the middle tooth step 11a<SP>1</SP>. The lever 5<SP>1</SP> is then released and restored to the middle position by the spring 27 which abuts against the bolt 29. When it is desired to shift the pawl 8<SP>1</SP> from the tooth step 11b<SP>1</SP> to the tooth step 11a<SP>1</SP> the lever 5<SP>1</SP> is pushed upwardly, as shown in Fig. 5, and a cam face 14<SP>1</SP> on the shift lever 5<SP>1</SP> lifts the pawl 8<SP>1</SP> out of the lower tooth step 11b<SP>1</SP>. Through traction of the cable 10<SP>1</SP> the shift gate 4<SP>1</SP> is rotated until the pawl 8<SP>1</SP> comes to rest in the middle tooth step 11a<SP>1</SP>.

Abstract: 1,020,773. Dishwashing machines. KENWOOD MANUFACTURING (WOKING) Ltd. July 10, 1964 [July 10, 1963], No. 27383/63. Heading A4F. [Also in Divisions F1 and G1. A pumping arrangement which may be located, as by a plate 25, in a well at the bottom of a dishwashing machine, comprises a pump 7, 8 forming part of a housing 1 which may be a plastics moulding, for example of polypropylene. The housing includes a pressure chamber 10 provided at its lower part with a liquid inlet 13 which may be of oval cross-section. As liquid enters the chamber 10 air is exhausted through a vent 21 until the liquid reaches a level at which it closes the vent. Further ingress of liquid increases the pressure of the air remaining in the chamber until a pressure value is reached, corresponding to the desired liquid level in the well, which operates a switch (not shown) coupled to the upper part of the chamber through an air outlet 23, Fig. 2 (not shown). Operation of the switch starts the machine and closes a solenoidoperated valve in the liquid supply, and it may operate the pump and/or any other suitable mechanism. The air vent and outlet are formed by tubes closed at their lower ends and provided with lateral bores. The air outlet tube has a circular water-splash shield at its lower end. The air vent tube extends upwardly from screw means 18 adjustable to vary the level of the vent 21 and thereby the liquid level at which the switch will operate.
