Abstract: 1321089 Making bearings; forging; shearing; punching VANDERVELL PRODUCTS Ltd 24 Sept 1971 [24 Sept 1970] 45605/70 Addition to 1180742 Headings B3A B3H and B3W [Also in Division F2] Apparatus for making a bearing liner from bearing strip material has a press and means for feeding the strip stepwise through the press, there being a tool operated by the press for making successive portions of the strip arcuate across the strip and coin pressing the outer surfaces of the acurate portions to the required finish, there being also a severing tool for severing the arcuate portions which is operated by a device timed to operate at a time different from that at which the press tool operates on the strip. The strip is formed into arcuate portions by a press described in parent Specification 1,180,742. The arcuate strip then passes to a capsule in which oil holes are punched in the strip by means of a fluid actuated punch 39 (Fig. 2). The arcuate portions are then separated by a capsule 50 (Fig. 3) having a die 55 which shears the strip against the edge of a semi-cylindrical member (not shown) on the piercing capsule side of the capsule 50. The shearing capsule includes a tool 60 which is mounted on a reciprocating rod 62 which co-operates with the die 55 to from notches in the liners. The die 55 and the rod 62 are actuated by pressurized fluid. Fluid is fed to the piercing and shearing capsules from an intensifier 73 via a master cylinder 78 (Fig. 5) which is controlled by a cam located on the crankshaft which operates the press 11. The arrangement is such that the press and shearing device do not operate simultaneously. The rod 62 is actuated by the action of a valve which opens after the shearing operation on each portion has been completed. The actuating pistons of the shearing and piercing devices are returned to their initial positions by fluid from an intensifier 85 which provides fluid at a constant pressure to the cylinders containing the pistons. The pressure of fluid supplied is less than the pressure of the actuating fluid and a relief valve is provided in the supply so that on actuation the fluid in the supply which tends to reset the pistons is bled away.

Abstract: 1331935 Catalytic reactors SHELL INTERNATIONALE RESEARCH MAATSOHAPPIJ B.V. 10 Dec 1970 [12 Dec 1969] 60647/69 Heading B1F [Also in Divisions C5] The hydroconversion of oils comprising residual material (see Division C4-5) is carried out continuously and substantially in the liquid phase by passing the reactants cocurrently in upflow or downflow through a bed or catalyst to which fresh catalyst is periodically introduced at the top and from which spent catalyst is withdrawn at the bottom. The fresh catalyst can be added as a slurry in the oil to be processed or recycle hydroprocessed oil can be used as the slurry oil. Oil feed and hydrogen enter the reaction zone 13 at 34 and the reaction products leave at 1. Fresh catalyst is periodically added to the reaction zone from a high-pressure catalyst inlet vessel 7 which has inlets 4 and 5 for fresh catalyst and for oil to slurry the catalyst. The flow of catalyst from vessel 7 is controlled by a high pressure cone valve 9; between the periodic additions of catalyst the conduit 11 is sealed by the gastight valve 29 after the conduit 11 and the valve 29 have been flushed by oil added through line 30. Catalyst is discharged from the zone 13 via a high pressure cone valve 9 and a gas-tight valve 30 leading to catalyst discharge vessel 22. The conduit 20 and the valve 30 can be flushed between periodic withdrawals of catalyst by oil added through line 32. Catalyst is withdrawn from the vessel 22 via a gas-tight valve 24 and oil is removed via line 27.

Abstract: 1333242 Tufting machine; needle drive adjustment SINGER CO (UK) 9 Aug 1971 [22 Aug 1970] 40559/70 Heading D1G [Also in Division F2] A tufting machine has an adjuster mechanism for readily varying the extent of oscillation of the needle-stroke shaft 19 thus providing a ready adjustment of the needle-stroke. As shown, an eccentric 13, on a driving shaft 12, through an eccentric strap 11 oscillates a bellcrank 14 and links 16, 18a to oscillate the needle-stroke shaft 19. The bell-crank 14 oscillates on a fixed pivot 24 and needle-stroke variation is effected by adjusting the pivot end 27 of the link 16 along an arcuate slot 17 in the bell-crank 14, an adjustment indicator scale 29 being provided adjacent the slot 27. The slot 17 may be replaced by a curved guide bar (not shown) or by an arcuate line of holes to which the link 16 may be selectively pivotally connected. The bottom-centre position of the needle remains the same irrespective of the needle-stroke adjustment, the timing of the needle-stroke thus being unaffected by the adjustment.

Title: Detector system
IPC: B61L1/16
Filed: 1971-01-13
Abstract: 1339971 Vehicle detector SANDS MEASUREMENT CORP 13 Jan 1971 1610/71 Heading B7N In a rail vehicle detection and counting system, two wheel detectors Eb, Wa are provided spaced apart a distance d greater than the distance a between wheels WA &c. of the vehicles' bogies but less than the distance b or c between bogies. The detectors are connected in a circuit which supplies a correct vehicle count irrespective of the number of axles in a bogie. Contact arm 46 of stepping switch 37 is moved to its 2nd and 3rd positions as wheels WA, and WB of the first bogie of vehicle RC1 pass over detector Eb and the switch arm is returned to its 1st position as these wheels move over second detector Wa. Thus bi-stable switch 60, 65 is operated twice (once for each bogie) at the passage of a vehicle and provides a single output to operate counter 68. Apart from a more complex movement of the stepping switch the operation is similar for the vehicle RC2 with three axle bogies. The system can include a vehicle weighing arrangement comprising weighing rails WR1, WR2 with weight gauges SG1, SG2 and a detector C which is operated by a vehicle wheel when its associated axle is over the weighing rails. Each time C operates the axle weight is stored in computer 85 and when the last vehicle axle is detected and operates counter 68 switch 95 is energized to transfer the total of the stored axle weights for the vehicle to printer 92. The system can be arranged, Fig. 5 (not shown), for both way operation or it can be an electronic system using logic circuitry, Figs. 6-9 (not shown).

Title: Vehicle wheel brakes
IPC: F16D65/18
Filed: 1970-06-24
Abstract: 1345158 Locking brakes "on"; transmitting- mechanism; slave cylinders GIRLING Ltd 10 June 1971 [24 June 1970] 30651/70 Headings F2E and F2F A "lock actuator" for a vehicle wheel brake comprises an extensible strut 8, 12 Fig. 1, normally free to be extended or contracted (during brake application or release), a friction clutch 6, 13, associated with the strut and having an engaged condition in winch it locks the strut against contraction, and a fluid-pressure-actuated motor means 14, 16 for effecting engagement of the clutch. As shown in Fig. 1, the lock actuator is incorporated in an hydraulic slave cylinder 1 for an internal shoe drum brake. Normally, a first auxiliary chamber 16 is first pressurized so that piston 14 urges spindle 12 in clutch-engaging direction, but a second auxiliary chamber 18 is also pressurized to apply a greater force via piston 17 to disengage the clutch. To apply the brakes, main working chamber 4 is pressurized, whereupon piston 2, moving outwards, directly engages tappet 6, while piston 3, moving outwards, engages non-rotatable nut 8 acting through a resilient overload device 11 on tappet 7. When the right-hand face of the head of spindle 12 is engaged by a ring fixed inside tappet 6, the spindle is rotated by the tappet's subsequent outward movement, because the left-hand friction face 13 of the head is not in contact with the tappet, and because of the spindle's reversible-thread connection with nut 8. The strut is thereby extended. On de-pressurization of chamber 4, shoe retraction forces acting through the tappet's and hence through piston 17 and nut 8 respectively cause contraction of the strut by reverse rotation of spindle 12. To apply the lock after brake application, chamber 18 is relieved of pressure, whereupon face 13 engages a surface of tappet 6 as piston 14 moves the strut leftwards. When chamber 4 is relieved, spindle 12 cannot rotate, so the strut remains extended to hold the brakes applied. Finally, pressure may be relieved in chamber 16. The lock may be released by pressurizing chamber 18. For ease of assembly, in Figs. 2 and 3 (not shown), tappet 7 is formed of three and two demountable parts, respectively, in one of which chamber 16 is formed in each ease. In Fig. 4, first auxiliary piston 14 is annular, in an annular cylinder 16 in left-hand tappet 6, and is engageable with the adjacent face of the spindle head.
