Title: Hydraulic control system
IPC: F15B11/16
Filed: 1970-06-08
Abstract: 1319482 Shovelling machines CESSNA AIRCRAFT CO 8 June 1970 [30 June 1969] 27562/70 Heading E1F [Also in Division F1] A hydraulic control system is such as to permit of control of the related operation of at least a first and a second hydraulic fluid actuated motor. In a preferred use of the system the motors involved are the boomswing, piston cylinder motor(s) 15 and shovelswinging motor(s) 19 and the system in such use permits of automatic retention of the level of the shovel as the boom is at least swung upwards. The system involves a supply of pressurised fluid, a reservoir and control valve means 23 communicating with the supply, the reservoir and the motors. The control valve means has a control element 31 that is shiftable to a position to both direct pressurised fluid to the first motor to actuate same and to direct hydraulic fluid displaced from the first motor as a result of its actuation to a flow divider 44 associated with the control valve means. The control divider directs a predetermined portion of the displaced fluid to the second motor to actuate same in correlation with actuation of the first motor. When such a system is used as described in a shovelling machine there is no longer need to match the motors so that the total volume displaced by the boom motor(s) is equal to that needed to extend the bucket motor(s) the required extent. Preferably a check valve is located between the flow divider and the second motor to prevent reverse flow from the second motor to the control means. A separate control means 26 is provided for the second motor, which means is such that it can override actuation of the second motor by said predetermined portion of displaced fluid. Three preferred embodiments of the system are described in detail.

Title: Internal combustion engine fuel metering systems
IPC: F02M69/42
Filed: 1961-08-02
Abstract: 919,630. Regulating. GENERAL MOTORS CORPORATION. Aug. 2, 1961 [Aug. 30, 1960], No. 28043/61. Class 7(6) In a fuel metering system for an I.C. engine, a passage for the delivery of fuel from an engine speed-responsive pump has arranged in series therein a pair of independently adjustable control valves each of which comprises a sleeve slidable in the passage and a fixed needle which extends coaxially within the sleeve, the sleeves being independently axially movable. Fuel passes from a reservoir 24, through a transfer pump 26, an engine speed-responsive pump 20 and along conduits 22, 52 to a chamber 54 in a metering valve 18 mounted on an air intake casing 10. A gear 56, mounted on the throttle shaft 16 to mesh with rack teeth 60 formed on a sleeve 36, causes the latter to slide in a bore 34, when the throttle is operated, and co-operate with a fixed but axially adjustable threaded tapered needle 44 to thereby vary the size of an orifice 50 and modify the quantity of fuel delivered by the pump 20. When the throttle is closed the orifice 50 is also closed and fuel for idling is bled through a by-pass passage 96 communicating with the supply conduit 52 and controlled by an adjustable needle valve 94. Enrichment of the fuel may be effected by operating a lever 74 which rotates a shaft 76 carrying a gear 78 meshing with rack teeth 82 formed on a sleeve 38, thereby moving the latter away from a fixed but adjustable threaded tapered needle 46. When the engine is shut-off the sleeve 38 may be moved to the right to allow its tapered portion 88 to co-operate with an O-ring 86 and thereby prevent fuel leaking to the cylinders. The fuel after passing through both control valves flows through conduits 28 to injectors 30.

Title: Apparatus for making slivers of staple artificial fibre
IPC: D01G1/10
Filed: 1937-10-20
Abstract: 504,352. Stapling continuous filaments. GROVES, W. W. (1. G. Farbenindustrie Akt.-Ges.) Oct. 20, 1937, Nos. 28575/37 and 32943 /38. [Class 120 (iii)] An apparatus for making slivers of staple artificial fibre from bundles of continuous adjacent the frame is perforated to permit the passage of bundles of filaments from the shafts or lap rods to the periphery of the lower disc, means for continuously feeding forward a tuft of fibres from the bundles on the lower disc and for holding the tuft so fed, means for cutting the tuft, and means for removing the cut tufts of fibres in the form of a continuous sliver without substantially disturbing the parallel arrangement of the filaments. As shown the bundles are carried on rods 2, 2a carried by a rotatable axle 1 which also carries the pair of discs 4; ti, the bundles 3, 3a being drawn over guides through the perforations 15 in the upper disc into the space between the discs and being continuously spread outwards over the margin of the disc 6. The filaments are drawn from the disc 6 at one or several points by pairs of feed rollers 13 and the bands fed forward are clamped to the lower disc by clips 5, 5a mounted on the upper disc and closed by the action of a stationary cam rail. The spread band is then cut by a rotating knife 7 or by a band knife, the clips 5, 5a being. then raised and the tufts of cut fibres being engaged and stretched by a rapidly moving draft device A; the resulting coherent sliver of cut fibres may be delivered to a winding device or to a can. The feed rollers and draft device may be driven at adjustable speeds and the knives may be oscillated and may have their cutting edges arranged tangential or inclined to the periphery of the discs. The tufts may be fed and clamped by a pair of travelling chains, the links of which have corrugated surfaces pressed together by pressing pieces, one of which is adjustable in length to vary the length of the tufts. The draft device may include belts the pressure of which can be adjusted so as to allow uncut tufts to slide through, or may comprise a card covered drum provided with rollers. In a modification the upper disc is replaced by an annular ring having a downwardly extending flange at its outer periphery and feet depending from its inner periphery and supported on the lower disc.

Filed: 1964-07-10
Abstract: 1,035,438. Thermal switches. ROBERTSHAW CONTROLS CO. July 10, 1964 [July 10, 1963], No. 28683/64. Heading H2B. A thermostat for controlling a domestic heating system comprises a cycling energyregulator in which the on-off ratio is proportional to the difference between ambient temperature and a desired temperature. A corrugated bimetallic strip 16 is adjustably mounted on a base 14 by means of a resilient U-shaped member 17 having an extension 18 acting as a follower on a cam 19 adjustable by a knob (Figs. 1 and 3, not shown) carried on cover 15. The cover 15 is open at top and bottom to provide ventilation so that strip 16 responds to ambient temperature. A contact carried on the tip end 25 of strip 16 co-operates with a contact mounted on the tip end 35 of a flat U- shaped bi-metallic member fixed by the end 34 of its leg 31. The other leg 32 thus provides ambient temperature compensation but is heated by a winding of resistance wire 42 connected in series with the contacts so that cycling occurs. The position of the contact on end 25 of strip 16 is determined by ambient temperature and the setting of cam 19 to a desired temperature and determines the on-off ratio of contact cycling time. The tip portion 45 is made of thinner bi-metallic material than the main part of leg 32 and is reversed as regards direction of bending thereby providing a quick action of the contacts, which is further increased by a closer winding of wire 42 on this portion 45. An upstanding heat shield 65 is fixed to base 14, as shown, to provide a chimney convection effect giving rapid removal of heat produced by wire 42. In another embodiment (Figs. 9 and 10, not shown) the adjustment provided by cam acts on the cycling bi-metallic member instead of the ambient temperature sensing strip. The legs of the cycling bi-metallic member may be made very close (Fig. 12, not shown) such that heat from wire 42 affects the other leg also and gives positive feedback to the " on " time.
