Title: Improvements in or relating to motor road vehicles
IPC: B62D61/02
Filed: 1957-04-01
Abstract: 854,861. Safety wheels and supports for motor-cycles; steering. MORTON, J. A. March 26, 1958 [April 1, 1957], No. 10492/57. Classes 79(5) and 136(1). In a motor road vehicle having a body which in use substantially surrounds the driver the road wheel system comprises two main road wheels 13, 14 arranged in tandem on the longitudinal centre-line of the vehicle and two auxiliary ground-engaging support members 19, 19 disposed one on each side of the rear main wheel 14, substantially in alignment with the latter laterally of the vehicle in order to give stability to the vehicle when at rest, the support members 19, 19 being retractable. A bench type seat 9 (Fig. 1) is provided to seat persons abreast and balancing is achieved by providing two separate and laterally adjustable backs 11, 12. When the vehicle is to be occupied by only one person, one of the backs may be removed and the other adjusted to a central position. Control of the steering is effected by means of a handle-bar 26 longitudinally slidable in an eye 27. In its central position the control 26 forms a normal handle bar. When the vehicle 10 is occupied by a driver and passenger the control 26 is slid into the position shown at 26a and is connected to a tiller for steering the vehicle. As shown in Fig. 4, the movement of the supports 19 from their retracted to their lowered positions may be effected by a manually operable lever 42 (Fig. 4) or by a foot pedal 47. Alternatively the supports 19 may be automatically raised as soon as the vehicle reaches a predetermined speed, the retraction of the members 19 being performed by a pump 39 driven from the road wheel 14 (Fig. 3). When a predetermined road speed is exceeded the pressure of the pump delivery overcomes spring loading within a hydraulic cylinder 35 tending to lower the supports 19. When the road speed falls below this predetermined value the spring loading overcomes the pressure of the pump delivery and the members 19 are lowered. Wheels 20 (Fig. 3) may be fixed to the members 19 or skids 21 (Fig. 4) to the supporting members. The members 19 are mounted on radius arms 30 extending from a cross shaft. 29 which acts as a torsion bar. Alternatively, independent torsion bars may be provided for each member 19. The manually operable lever 42 of Fig. 4 may be used to override the control of the cross-shaft 29 effecfed by the hydraulic cylinder 35 and rotate the cross-shaft to cause the members 19, 19 to be lowered into their ground engaging position.

Abstract: 778,663. Controlling vehicles. MASSEYHABRIS-FERGUSON (SALES), Ltd. April 20, 1954 [April 17, 1953], No. 10546/53. Classes 79(2) and 79(5). [Also in Group XXXIV] In a vehicle (particularly a tractor) braking system of the kind in which the brakes of both rear ground wheels are adapted to be actuated in unison by mechanism including a crossshaft 30 which traverses the tractor body and from which separate brake actuating connections extend to both brakes, the brakes may be actuated individually by means of the appropriate pedal 2 which when depressed actuates shaft 1, against the action of return springs 3, to apply the appropriate engine-driven rear ground wheels of the tractor or simultaneously by means of pedal 5 which acts as a main actuator. One of the pedals may be provided with an alternative actuator in the form of a hand lever 4 preferably secured to the left-handside pedal 2 to enable the driver to leave his left foot free for actuation of the clutch pedal. The pedal 5, which actuates both brakes simultaneously, has a hub 6 which is attached to a sleeve 7 rotatable in bearings in the tractor casing. The equalizing device comprises a floating compensator lever 20 which has diametrically opposed and equi-distant pivot joints 22 and 23 with reference to the axis of the cross-shaft 30 which rotates within the sleeve 7. The base of the lever 20 has a pressure receiving member 21 which has an abutment face 21A that is engageable by a pin 19 on the pedal 5. The pivot joint 22 connects the compensator lever 20 with an arm 29 fixed to the cross-shaft 30 and the pivot joint 23 connects the compensator lever 20 with an adjustable brake-actuating connection 24-27. The other end of the crossshaft 30 carries an arm 28 for actuating the left-hand brake through a similar brakeactuating connection 24-27. In operation, when the main pedal 5 is depressed, the pin 19 engages the abutment face 21A of the compensator lever 20 to resolve the pressure into two oppositely-directed parallel forces, i.e. a couple, on the pivot joints 22 and 23. Thus the lever 20 tends to rotate about the. pivot 22 pulling on the pivot 23 and applying the right-hand brake. Similarly, the lever 20 tends to pivot about the pivot 23 and push the pivot 22 rearwardly to apply the left-hand brake through the arm 28. Thus substantial equal braking efforts are applied to both vehicle wheels. A pawl-andratchet retaining mechanism 11 similar to that described in Specification 723,492 is provided for the main pedal 5.

Filed: 1967-03-07
Abstract: 1,178,745. Making circuit boards. INTERNATIONAL BUSINESS MACHINES CORP. 7 March, 1967 [30 March, 1966], No. 10554/67. Heading B3A. [Also in Divisions C1 and H1] In a method of making a multilayer printed circuit board, circuit patterns 16, 18, 20, Fig. 2, are formed on a plurality of green ceramic sheets 10, 12, 14 with a paste comprising powdered metal or reducible metal compound in a volatile binder, through-holes 22, 24, 26 in said sheets also being filled with said paste; the sheets are then stacked and fired to sinter the sheets together, Fig. 5, to convert any metal compound to the metal, and to cause the metal to form capillary paths 42 along said circuit pattern; finally the said capillary paths are filled with molten conductor metal 52. A preferred ceramic for the sheets is zirconium alkaline earth porcelain (ZAEP); aluminas, beryllias, forsterites, steatites, and mullites may also be employed. Preferred metals include Mo, Mo-Mn, Zr, Fe, Cb, W, Ti, Ta, and mixtures thereof; compounds of the said metals and oxides of Li-Mo may alternatively be used. The capillary paths may be either metallized tubes, as shown, or porous lattice-like structures; they are filled by immersion in a bath of molten metal, e.g. Cu or Al, in a reduced pressure atmosphere; alternatively, metal preforms are butted against the capillary ends and melted. A preferred composition of ZAEP is:- After milling for 8 hours the slurry is dried, pulverized, calcined, repulverized and micromilled, after which it is mixed with resin, solvents, and wetting and plasticizing agents in the following proportions:-  In a first example, ZAEP green sheets are screen printed with a circuit pattern of paste comprising 40 gms powdered MoO 3  and 13À5 gms. medium containing betaterpenyl and ethyl cellulose. After stacking, the sheets are subjected to a burn-off in air at 400 C. followed by firing in dry H 2  at 1210 C. Capillaries are filled by immersion in a molten Cu bath at 1140 C. In another example, terephthalic acid is added to the paste, the sintering is carried out at 1285 C. in, a moist H 2  atmosphere, and the capillaries are filled in an Al bath at 700 C. Other examples using Mo-Mn powder to form the paste are described in the Specification.

Title: Hydraulic systems
IPC: B62D5/087
Filed: 1971-04-21
Abstract: 1342503 Power steering systems MITSUBISHI JIDOSHA KOGYO KK 21 April 1971 [21 April 1970 (2)] 10598/71 Heading B7H [Also in Divisions F2 and G3] In an hydraulic system including an hydraulic pump adapted to discharge a given amount of oil per unit displacement of an actuating means and a sliding spool or rotary control valve, the displacement of the spool or rotor is proportional to either the velocity, or the velocity and the amount of displacement of the actuating means. In a first embodiment, Fig. 9, the system forms part of a power assisted vehicular steering mechanism and the pump discharges oil into valve chamber 57c or 58c through port 64c or 65c to move the spool 51c in accordance with the angular velocity of the steering wheel. A restricted orifice 70c interconnects chambers 57c and 58c and controls the pressure difference therebetween according to the rate of flow through the orifice, hence the spool displacement is dependent on the angular velocity of the steering wheel. The spool 51c controls the oil flow path from a supply port 62c connecting with a further pump to either port 60c or 61c which connect to different sides of a motor (32) (Fig. 8, not shown) which effects steering movement. Port 63c connects with a reservoir. In a similar arrangement (Fig. 14, not shown), the spool shaft (50), on which the spool (51) is mounted, is mechanically linked to the steering column (Fig. 13, not shown) via a pitman arm (18), hence displacement of the spool is dependent on the amount as well the velocity of displacement of the steering wheel. The hydraulic actuation of the spool and its control action is similar to that described for Fig. 9. In a further embodiment, Figs. 11 and 12, a rotatary valve is included in the system and is connected to the vehicle steering wheel only via the pump discharging oil in accordance with the unit angular rotation of the steering wheel. This pump discharges oil via port 164c or 165c into chamber 157c or 158c defined between a bearing portion of the housing 140c and the rotor 151c. The rotor exposes different areas at each end of each chamber. Springs 154c are situated between the rotor and housing and the chambers are interconnected via orifices 170c which control the pressure difference therebetween according to the flow rate therethrough, hence displacement of the rotor is dependent on the angular velocity of the steering wheel. The rotor controls supply of oil to chamber 182c or 183c from a supply port 162c connected to a steering actuating pump. The piston 181c controls steering movement via pinion shaft 19c. In a similar arrangement, Fig. 17, the rotor 151 is mounted about the end of the steering shaft 16a which is connected to the rotor housing via a torsion bar 155. Rotor actuating chambers and inlet and outlet ports are provided as before, the chambers 157 (158) being formed in the steering shaft and rotor. In this embodiment displacement of the spool depends on both the amount and velocity of displacement of the steering wheel.

A clutch comprising plane, or, as shown, frusto-conical friction engaging surfaces 45, has torque-assisted engagement effected by the camming action of rollers 52, pivoting about pins 51 fast in a shaft 41 and running on inclined surfaces 53 at the back of a friction ring 47, clutch engagement being initiated on sliding axially a control sleeve 49 connected to the friction ring through a pin-and-slot connection 64, 66, Fig. 7 (not shown), the ring engaging its coacting friction surface and thus being turned a limited amount relatively to the control sleeve and to the rollers. Spring- biased bale detents engage in pockets 62 &c. in the control sleeve 49 to hold the latter in the clutch engaged &c. positions, the pockets having surfaces so inclined that the bale detents bias the control sleeve in the clutch-engaged direction. As shown, two alternatively engaged similar friction rings 47, 48 are arranged on opposite sides of the rollers 52, and springs 58 co-operate with sliding plates 56, 57 to bias both rings to their disengaged positions. In a modification, Figs. 1-3 (not shown), a single friction ring is mounted on one side of the camming rollers, and disengaging springs act between the friction ring and the mounting of the roller pivot pins. Reference has been directed by the Comptroller to Specification 909,507.
