Title: Hydraulic braking systems
IPC: B60T8/44
Filed: 1973-10-25
Abstract: 1468014 Hydraulic brake systems; anti-lock brake systems CLAYTON DEWANDRE CO Ltd 16 Oct 1974 [25 Oct 1973] 49732/73 Heading F2F An hydraulic braking system has a master cylinder 1 operable to actuate the brakes 4 on one axle and also to actuate a reaction valve 5 in a full power circuit 6, 7 8 whereby pressure fluid from an accumulator 8 is supplied to the brakes 9 on a second axle and to a servo cylinder 10 for boosting the output delivery from the master cylinder 1 to the brakes 4; the system also incorporates at least one solenoid valve 14 forming part of an anti-lock system and operable under the control of the anti-lock system logic to vent one or more of the brakes 4, 9 to a low pressure reservoir 6 of the full power circuit. In the embodiment of Fig. 1, fluid pressurized by master cylinder 1 is led by a line 2 to an output cylinder 3 hydraulically connected to the brakes 4, and the output of the master cylinder 1 or the movement of its piston, actuates the valve 5 to supply fluid from the accumulator 8 to the brakes 9 and the servo cylinder 10. The piston 11 of cylinder 10 is thereby moved to displace the piston 12 of output cylinder 3 to augment the master cylinder pressure and to close a bore 13 therein which otherwise directly connects the brakes 4 with the master cylinder 1. In this embodiment a two-way solenoid valve 14 is inserted in a line 15 between valve 5 and brakes 9 and is operable to decrease or cut-off line pressure to brakes 9 and to vent line 15 to reservoir 6, for example, via a port 16 in valve 5. For anti-lock control of brakes 4 only, a solenoid valve (17) is inserted in a full pressure line (18) to the servo cylinder 10 to vary the degree of boost provided by the servo cylinder 10. However, an additional solenoid valve (19) may be inserted in the line 2 which valve is energized by the system logic to cut-off flow from the master cylinder to the output cylinder and to vent the servo side of the output cylinder piston via a line (20)-this prevents a rise in pressure in the master cylinder forcing back the servo piston 11 to open bore 13 and thereby override the anti-lock control. Fig. 2 (not shown) illustrates such a system which, however, also has anti-lock control to both first and second axles simultaneously and includes both solenoid valves (14) and (17). Any of the above systems may also include at least one inlet solenoid valve (14a, 17a) to give a pressure hold facility. In the embodiment of Fig. 3, each wheel brake 4, 9 has its own two solenoid valves 14, 14a or 17, 17a. Two servo cylinders 10, 10a and two output cylinders 3, 3a are provided for respective brakes 4. If desired anti-lock control may be provided for individual brakes on one axle with the brakes of the other axle under common control.

Abstract: 1,184,990. Determining gas concentrations electrically. AVESTA JERNVERKS A. B. Oct. 28, 1968 [April 29, 1968], No.51045/68. Heading G1N. Apparatus for determining e.g. the carbon content of steel comprises means for converting the carbon to CO 2  gas which is separated by filters and a freezing trap, and its mass determined by electrically measuring the pressure in a given volumetric space. As shown Fig. 1, the test steel sample in a furnace 3 is fed with oxygen and the resulting oxygen and CO 2  mixture fed to a Venturi tube 11 where the gases are initially cooled in the expansion chamber following the restriction, and separated in a freezing trap 12, described below. A plurality of filters are located in the gas path. The pure CO 2  is then fed to a differential pressure gauge 17, comprising two chambers separated by a conductive diaphragm, producing a variable capacitance proportional to the CO 2  pressure, which is measured at 23 and indicated at 24. The unit 23 increases the volume occupied by the CO 2  if the pressure measurement exceeds a predetermined value, by opening a valve 18. The system is cyclically controlled by a timer. The freezing trap 12, Fig. 2, comprises a lower vessel 39 containing liquid nitrogen which is heated to force the liquid into an upper vessel 34 to a level sensed by a transducer 36. The gas mixture of oxygen and CO 2  is fed through concentric tubes 30, 31 immersed in the liquid in the upper vessel, whereby the CO 2  condenses and the oxygen passes on. Subsequently the valve 42 in the lower vessel is opened, the liquid nitrogen in the upper vessel returns to the lower vessel, and a heater 32 round tubes 30, 31 is energized to vaporize the CO 2 .

Abstract: 1,118,235. Proximity detectors. TATEISI ELECTRONICS CO. Nov. 16, 1966 [Nov. 23, 1965], No. 51373/66. Heading G1N. In a proximity detector, the sensing circuit is so arranged as to make its operation independent of the length of cable connecting the sensing element to the rest of the circuit. As described with reference to Fig. 1, a proximity detector comprises an inductance 42 and capacitance 44 connected in series and connected by a cable 48 to a second inductance 36 and capacitance 38, the values of the inductances and capacitances being chosen so that they function as a series resonant circuit. Resistance 50 is large compared with the resistance of the cable. Either inductance 42 or capacitance 44 may be affected by the proximity of a body. Inductance 36 is coupled to an inductance 30 in the tank circuit of an oscillator 10, the output of which is connected via diode 18 and a waveshaping Schmitt circuit 22 to a relay or indicator 26. The sensing circuit 46 may be tuned to the frequency of the oscillator so that the presence of an object detunes the circuit 46 to allow onset of oscillation; alternatively, the presence of an object can cause circuit 46 to become tuned to the oscillator frequency to stop oscillation.

Abstract: 1397224 Valves GESTRA-KSB VERTRIEBS GmbH & CO KG 12 Nov 1973 [2 Dec 1972] 52351/73 Heading F2V [Also in Division F4] Draining of condensate or other liquid from a housing 1 having an inlet 2 and outlet 3 is controlled by a float 7 connected via lever 8 and rod 6 with a valve closure member 11 co-operating with fixed seat 10. The latter is contained within a cylinder 5 having radial ports 17 for the entering liquid which then flows through annular flow restricting clearances 15, 16 between the outer and inner surfaces of an annular piston 14 and cylinder 5 and seat member 9 respectively, thus substantially equalizing the forces acting on the upper and lower surfaces 19, 20 of the piston whilst the valve is closed. A member 13, which may be resilient, connects piston 14 to rod 6 such that as soon as float 7 causes the latter to lift valve member 11 off seat 10, the sudden drop in pressure acting on surface 19 as the liquid drains through outlet 3 causes piston 14 to move rapidly upwards thus opening the valve still further. The construction also assists rapid closing of the valve when the liquid level in housing 1 has dropped sufficiently. In a modification the cylinder 5 is tapered such that the flow restriction varies with the position of piston 14 along its stroke. The flow restriction may be formed as an axial annular gap between end surfaces of piston 14 and cylinder 5.

Apparatus for transporting packages and for shrinking membrane portions of the packages around products enclosed by the membrane portions comprises a structural frame 1 having cam tracks 5, a carriage mechanism 6 having rollers 9, 10 supported in the cam tracks, vacuum actuated lifting devices 30 attached to the carriage and arranged to lift and release a package, a conveyer belt 53 and package heating apparatus 56. A round table machine 60 as described in Specification 1,136,263 advances packages 61 below suction pads 35, 36 of the lifting devices 30 which are supported by a bar 8 on the ends of which are mounted the rollers 10. The bar 8 is connected by pivoted links 15, 16 to a bar 7 having rollers 9 at each end. The bar 7 supports an air chamber 20 connected by flexible hoses 27 to each of the three lifting devices 30. A microswitch positioned adjacent one end of the cam tracks 5 operates a vacuum supply source (not shown), thereby causing the suction pads 35, 36 to lift packages whilst at the same time a piston 48 actuated by an air cylinder 42 withdraws the carriage mechanism 6 until a microswitch positioned at the other end of the cam tracks is operated which releases the vacuum thereby depositing the packages on a moving conveyer belt 53. The conveyer belt advances the packages through a heat chamber 56 where the membrane portions of the packages are shrunk to conform to the shape of the enclosed products.
