Title: Motor vehicle fluid temperature control systems
IPC: B60H1/00
Filed: 1975-09-04
Abstract: 1490646 Cooling IC engines; ventilating vehicles VAUXHALL MOTORS Ltd 18 Aug 1976 [4 Sept 1975] 36471/75 Headings F4U and F4V In a system of controlling the temperature both of a vehicle engine coolant and of air delivered to the vehicle ventilation system, coolant is passed by a pump 3 from an engine jacket 2 to a first heat exchanger 4 only when a first temperature dictated by a thermo-responsive valve 10 occurs and is recirculated through a hose 7 to the jacket until a second higher temperature is reached, which temperature is sensed by a second thermo-responsive valve 11 which closes the hose 7 and allows the coolant to pass from the exchanger 4 to a second heat exchanger or radiator 8 and thence through a hose 9 to the jacket. A fan 18 associated with the radiator may have a viscous drive coupling with the engine so as to be inoperative at engine speeds above a predetermined figure or it may be electrically driven and responsive to coolant temperatures above the second temperature. The heat exchanger 4 and an associated fan 14 responsive to a thermo-sensor 19 provide hot air for the ventilation system which air passes selectively through a a duct 21 for exhaust or through a duet 22 into the vehicle interior, the temperature being regulated by manual adjustment of a valve 26 controlling the quantity of heated air and fresh air introduced thereto through a duct 24 by a manually-controlled fan 25. A manual switch 28 may override thermo-control of the fan 14.

In a compressed fluid braking apparatus for railway vehicles of a kind having a distributer valve device D and a relay valve device VC, the latter being adapted in dependence upon the supply thereto of compressed fluid from an auxiliary reservoir RA under the control of the distributer valve device D to control in turn the admission to, and its release from, a brake cylinder CF of compressed fluid derived from a main reservoir RP, the apparatus is provided, in addition to the usual brake pipe CG in dependence upon variations of the pressure of compressed fluid in which the distributer valve device D is controlled, a supplementary socalled supply pipe CP which in the same manner as the brake pipe is adapted to be coupled between adjacent vehicles so as to extend continuously down a train of vehicles and from which the main reservoir RP is charged with compressed fluid, whereby the capacities to be recharged from the brake pipe CG following a brake application are relatively small with the consequence that, particularly in long trains, a quicker release of the brakes down the train is possible. The supply pipe CP is charged to double the normal fully charged value of pressure in the brake pipe CG and the supply pipe CP and the main reservoir RP are in permanent communication through one-way check valve CAR. A check valve CL of restrictive flow capacity is inserted in the line between the main reservoir RP and the auxiliary reservoir RA enabling the main reservoir to be charged from the brake pipe CG should there be a failure in the supply pipe CP.

Abstract: 907,851. Chimneys. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 19, 1958 [Nov. 29, 1957], No. 37344/57. Drawings to Specification. Class 25. [Also in Group XXXIII] The wind-excited oscillations of a chimney stack are reduced or eliminated by the provision on the external surface of the stack of a fixed stake or rib extending helically for a significant part of the height of stack, the pitch, radial height, longitudinal extent, and number, of stakes being such that the formation of regular vortex streets downstream of the stack is reduced to negligible proportions or eliminated. The stake may extend over the upper one third to two thirds of the height of the stack. In the case of a wind tunnel test body of constant circular section, oscillation in the plane perpendicular to the direction of air flow is significantly reduced by the provision of three equally spaced helical strakes, of radial height between one fifth and one fiftieth of the diameter of the body, the helix pitch being about fifteen diameters, or seven and a half diameters. In the case of a conical body, there may be a constant ratio between the helix pitch and body diameter at any station.

The crop is picked up from a windrow by a drum 58 carrying tines and fed into the pressing space through a draw-in gap 46 where it is rolled by conveyor belts or webs 32, 34-38 on rollers 40, 41 driven by chains 48 Fig. 3. No pressure is exerted on the roll until it fills the pressing space, it is then compressed by the continued introduction of material, so that the roll bale is of higher density in its outer regions than in its core. When a desired pressure is reached the rear part 10 of the housing is swung about a pivot at its top under the action of a hydraulic cylinder 18, Fig. 3, so that the bale can be discharged. In an alternative embodiment Fig. 4 the conveyor belts 39 are replaced by conveying drums 66 &c spaced adjacent one another around the pressing space. A latch device 20-26, Fig. 3, holds the rear part of the housing 10 in a closed position until the cylinder 18 is actuated.

Class 29 In ice-cream freezers having a horizontal cylinder 1 refrigerated by an evaporator 2 and provided with a mixer 4 and, at one end, a dispensing tap 9, mix incorporating air is introduced into the cylinder through a pipe 33 when necessary by a continuously-running gear pump 13. The pump has two gears 14, 15 drawing in mix from tank 10 through pipe 16 and valve 17 and air through valve 18 respectively, the latter being incorporated in the mix by the pump. A non-return valve 45 in the exit of pipe 33 prevents back-flow from the cylinder 1. A relief valve 42 in pipe 33 vents excess mix back to tank 10. The front plate 29 of pump 13 is loaded by springs towards the pump casing and these give if the discharge pressure becomes too high so that plate 29 moves away from the casing to relieve the pump. The mix is pre-cooled in tank 10 by a heat conductive member 12 between the tank and evaporator 2.

The diaphragm 15 receives fluid pressure from a port 28 and acts on a diaphragm plate having two parts 16, 19 which move together until the edge 21 of the part 19 engages the wall of the chamber 3 (Fig. 2, not shown). Further depression of the part 16 is possible, under the action of a member 10 carried by a rod 11 on the piston 4, until a flange 18 on the part 16 engages a flange 26 on a flanged tube 25 attached to the part 19 (Fig. 3, not shown). Return of the piston is effected by fluid pressure applied to a port 8. The pressure operation is for service braking, and the spring operation for emergency or parking.

Filed: 1974-09-02
Abstract: 1461527 Valves ATELIERS DES CHARMILLES SA 2 Sept 1974 [4 Sept 1973] 38239/74 Heading F2V A valve operable solely under still water conditions chiefly for forced flow mains, comprises a valve shutter 2, carried by two arms 3 pivotally secured to supporting members 5, and a seat 6 on the valve body, members 5 being urged with the shutter towards the seat by the hydraulic thrust in the upstream side 8 of the valve. Members 5 are elastically yieldable, and the shutter is pivoted by an hydraulic jack 9. In a modification, the bearings 4, Fig. 4, are formed as pistons which are adapted to be moved in the direction of the axis of the valve so as to seat the valve. In a further modification, the axial movement of the shutter is provided due to a clearance which is initially taken up by movement of the shutter and its bearings towards or away from the seat. In operation, a turbine distributor supplied by the valve is shut-off and the pressures on the upstream and downstream sides of the valve are therefore balanced. Jack 9 is actuated so as to pivot shutter 2 from the Fig. 1 open position, to the valve closed position. Pressure is then reduced in the downstream side by closing a cock 11 and opening a cock 14, and due to the pressure difference shutter 2 is forced against the seat, during which time supports 5 flex, or pistons 4, Fig. 4, are moved axially, or bearings 4, Fig. 9 (not shown), take up the slack 19. The reverse of this operation is carried out when the valve is to be opened.
