Title: Carburetor control mechanism for an automotive gasoline powered internal combustion engine
IPC: F02M1/10
Filed: 1972-11-21
Abstract: 1386648 Spray carburetters NISSAN  MOTOR CO Ltd 21 Nov 1972 [8 Dec 1971] 53640/72 Heading FIB An I. C. engine comprises a fuel supply system supplying a desired ratio of air/fuel mixture to an idling hot engine, the supply system responding to temperature sensitive means responding to low engine temperature and also to the concurrent intake manifold depression sensed by sensing means to supply a desired air/fuel mixture ratio for idling a cold engine,.the temperature sensitive means causes retarded ignition timing when the engine is idling when cold. When the engine is started, a switch 33 is closed because the engine is idling and cold, a switch 34 is closed because the engine is cold and closure of ignition switch 35 energizes the coil of solenoid valve 31 to admit inlet manifold vacuum to chamber 24. The downward movement of spring-loaded diaphragm 26 causes opening of throttle 16 through the lever system 29, 30. Simultaneously a control 36 retards the ignition timing to facilitate rapid warm-up. In this operative condition a coolant temperature responsive member 52 is away from an aperture 50 to admit air into chamber 47 and thus into chamber 40 thereby preventing the inlet manifold vacuum acting in the latter to move diaphragm 42 leftwards to open choke valve 14. When the engine has warmed up the switches 34, 33 are opened to de-energize the coil of solenoid valve 31 to admit air into chamber 24 causing disengagement of the lever projections 29a, 30a. Simultaneously the ignition retard is released and engine acceleration is controlled by accelerator 20. As coolant temperature increases the member 52 restricts aperture 50 thereby allowing the inlet manifold vacuum to rise in chambers 47 and 40 thus causing the diaphragm 42 to open the choke valve 14. During normal running the choke valve 14 is kept fully open. When the accelerator 20 is depressed the inlet manifold vacuum is reduced thereby tending to close choke valve 14 but this is prevented by the engagement of the lever projections 54a, 56a. When the accelerator 20 is released the projections 54a, 56a are disengaged to allow the choke valve 14 to be controlled by actuator 38.

Abstract: 1,220,887. Sealing bale ties. SIGNODE CORP. 19 Nov., 1968 [4 Dec., 1967], No. 54840/68. Heading B6P. The strapping tool described in Specification 996,608 is modified by having the spreader links 150 connected to the jaw members 152 by pin and slot connections 166, 168. The slot 168 in each spreader link extends in a direction at right angles to longitudinal axis of the spreader link. The downwardly and outwardly facing straight edges of these slots 168 function as cam surfaces during the initial downward movement and exert a downward and outward component of spreading action on the pins 166. This spreading action rapidly swings the jaw members 152 in opposite directions to preliminarily wrap the flange of the seal S around the overlapping portions of the strap (Fig. 4). The reaction force for this cam-initiated spreading action is provided by opposed contacting edges 170 of the two spreader links 150. When the pins 166 reach the upper ends of the slots 168 (Fig. 4), a true toggle action then takes place for the remainder of the crimping cycle, the jaws proper 162 moving inwardly toward each other to effect the notching operation on the seal S, (Fig. 5). It is possible to reverse the pin and slot connections between the spreader links 150 and the jaw members 152.

Filed: 1968-11-21
Abstract: 1,210,108. Forming reinforcement spacers. MAX FRANK G.m.b.H. & CO. K.G. 21 Nov., 1968 [21 Nov., 1967], No. 55314/68. Heading B5A. A plurality of asbestos cement spacers, for positioning steel reinforcements in a concrete construction unit, are simultaneously formed by' transversely cutting a preformed strip of asbestos cement with a cutting tool comprising a plurality of rotating blades which are brought down on to the horizontally supported strip. The strip may be cut in the unset condition by knife discs, or in the set condition by circular, toothed saws or diamond saws. When cut in the unset condition, the strip 3 is extruded by a worm 1 or a piston press into a guiding groove 5 in a support 4. The extrusion may be halted during the cutting operation which is effected by continuously rotating blades 7 which are reciprocated on a shaft 8 to pass through the strip 3 via transverse grooves 6 around groove 5. The shaft 8 may be mounted, Fig. 3 (not shown), for reciprocation into and out of cutting engagement, at one end of a twoarmed lever the other end whereof is arcuately reciprocated by a crank drive, and which other end also carries a motor for rotating the shaft 8. The intermittent operation of the extruder and reciprocation of the shaft 8 are automatically controlled from contacts associated with a measuring wheel 10 and the crank drive. Alternatively, Fig. 4 (not shown), the two-armed lever carrying the shaft 8 may continuously rotate, the lever pivot being located vertically above groove 5, or the shaft 8 may be vertically reciprocated into the cutting position by a piston-cylinder drive, Fig. 5 (not shown). With continuous extrusion of the strip 3, a travelling cutting device is used. Where the strip is cut in the set condition, the strip is cut from the extrusion die and removed on the support 4, which is replaced by a further support.

Title: Method and apparatus for supplying fluid pressure
IPC: D05C15/00
Filed: 1967-12-07
Abstract: 1,204,728. Fluid-pressure servomotor systems. CALLAWAY MILLS CO. Dec. 7, 1967 [Dec.20, 1966], No.55756/67. Heading G3P. [Also in Divisions D1 and F1] A rotary compressor 22 supplies a multineedle tufting machine via cooler 26, and separator 28 and is unloaded when the pressure in delivery line 9 reaches a predetermined level by means of pilot valve 96 which supplies air to servomotor 94 to open vent valve 30. The latter actuates a switch 168 in the open position to energize a timing relay 170, and if the pressure in line 9 remains high, due to a stoppage or the tufting machine, the relay 170 closes to energize relay 172 to thereby de-energize solenoid valve 82 to supply air to a piston (50) to raise the latter to close the suction line of the compressor. A pressure switch 184 in circuit with pole 183 of relay 172 holds the latter in position until the pressure in line 9 drops to a predetermined low level. The unloading piston (50) thus comes under the control of switch 184. In the unloaded state, the compressor delivery is led to atmosphere by line 62 and valve-member (74) unseated by piston (50); the pump thus runs in a partially evacuated casing to reduce the motive power. The pilot valve 96 comprises Fig.4 (not shown) supply and exhaust valve-members (148, 156) actuated by stem (152, 154) extending from spring-loaded diaphragm (128). The servomotor (94) has a diaphragm (112) which positions valvemember (102) in the vent line. In a modification Fig. 5 (not shown) the timing circuit is removed and the vent valve allows variably restricted escape of air when opened by the pilot valve. If the line pressure continued to rise, a pressure switch (201) opens the circuit to solenoid valve (82) to close the suction valve as above. The switch (201) closes the solenoid valve circuit at a pressure less than that at which pilot valve (96) vents the vent valve servomotor. The suction line may contain a check valve (218) Fig. 7 (not shown) by-passed by a line containing a second compressor which acts in series with the first compressor when driven. The compressors have a common unloading mechanism as above.

Abstract: 1287737 False-twisted yarns C W TASSELL 26 Nov 1969 [26 Nov 1968] 55924/68 Heading D1F In a method of false-twisting a continuously travelling synthetic yarn in an at least partially plasticised condition, the twisting is effected using a plurality of coils 9a of continuouslytravelling yarn 9 wrapped around the yarn 8 to be twisted so as to frictionally engage and apply a torsional force thereto, a braking force being applied to at least one of said coils following the leading end coil so as to increase the tension in and hence the grip of the coil or coils leading the coil or coils to which braking force is applied. In a preferred embodiment a yarn Y is drawn from a supply bobbin 1 and passed to a contact heater 3 via guide rolls 2. The plasticised yarn Y is then passed round a reversing roll 4 and wrapped around the approaching yarn at a point 5. The yarn gradually cools and is wound on a bobbin 6. A separate yarn may be used as the wrapping yarn. The braking force may be transmitted by a pad 10 of friction material or a roller or by a hollow roller which bears with its inner surface on the coils. To prevent deflection of the yarns, two such pads or rollers may be applied at diametrically opposed locations.
