Abstract: 1,232,994. Power-operated screwdrivers. DESOUTTER BROS. Ltd. 2 July 1968 [31 July, 1967], No. 35088/67], Heading B3N In a power-operated screw-driver in which power is transmitted from a pneumatic motor 2 by way of driving and driven dog clutch members 32, 33 which are relatively rotatable under the action of the driving torque and the dog clutch members have interengaging ramps (33a) (Fig. 4, not shown) which slide over one another under a predetermined driving torque, a motor control valve is provided which is actuated by a rod 8 extending axially of the tool to stop the motor on axial movement of the rod caused by relative movement of the dog clutch members. Preferably the control valve 1 is biased by air pressure to remain closed, when once closed by the rods, until the rod is withdrawn and the air supply to the valve interrupted. In operation the rod 8 and a valve operating rod 20 are moved an initial distance (Fig. 4) by pressure of the screw-driver on a screw, to open the air valve 11 when air passes through bores 12, 13, annulus 14, chamber 15 and passage 16 to drive the motor. The motor drives a cup-shaped member 28 with slots 30 in which are slidable ears (31) (Fig. 3, not shown) of the clutch driving member 32. On reaching a predetermined torque, the clutch member 32 moves, in opposition to a central spring 35, together with a block 42, which actuates the rod 8 and is mounted on a rod 40 passing through a transverse bore of the clutch member 32. The clutch operating torque can be adjusted by screwing an internally threaded bevel gear 50, by means of a removable key 51, along a sleeve 36 to adjust the pressure of the control spring 35. The further movement of the rod 8 lifts a piston valve 18 until its maximum diameter portion closes the passage from the annulus 14 to the chamber 15 and hence the air supply to the motor, the unbalanced air pressure below the piston valve lifting it smartly and holding it in place until the air supply to the inlet 10 is interrupted. In an alternative screw-driver (Figs. 5-8, not shown) provided with finger-button controlled starting and reversing valves (92) and (66) in a pistol grip handle the rod (8), when the desired torque is reached, lifts a ball (57) to permit pressure air to pass through a passage (55) to the lower end of and to lift a piston valve (59) thereby closing off the passage (58) and annulus (61) from the annulus (60) and passage (63) between the reversing valve and motor.

Abstract: 1,257,735. Controlling combustion of waste gases from a convertor. NIPPON STEEL CORP. 15 Jan., 1969 [16 Jan., 1968], No. 2305/69. Heading F4B. [Also in Divisions G2- G3] Waste gases from a top blown converter 1 flow through a waste gas cooling system 5 and a dust collector 7 to an outlet flue 9. The pressure or temperature of the cooling steam or water flowing through line 6 in the system 5 is measured by detector 15, and through controller 16 and actuating means 14<SP>1</SP>, 17<SP>1</SP>, is used to vary the position of movable skirt 3 above the top of converter 1, to control the clearance between them and therefore regulate the flow of ambient air into the hood 4 of the waste gas cooling system 5. This controls the combustion of CO in the waste gases, to produce a stable thermal load throughout the blow period, to maintain the pressure or temperature detected by detector 15 constant. When the clearance between the skirt 3 and the top of converter 1 falls below a predetermined value as shown by indicator 18, the gas pressure within the hood 4 measured by gauge 12 is maintained slightly below the ambient air pressure by regulation of dampers 8 through controller 13 and actuating means 14 and 17. At clearances above this predetermined value selector switch 19 puts this hood pressure control system out of operation.

Abstract: 1297541 Fluid Pressure servomotor systems ROBERT BOSCH GmbH 24 Feb 1970 [25 Feb 1969] 8710/70 Heading G3P A control valve comprises a housing 1, a control member 3 slidable in a bore 2 of the housing for controlling a connection between inlet 4 and an outlet 5 and having an end face 34 acted upon by fluid from an independent source via a passage 17 and a throttle 19 in a longitudinal bore 18 of the control member 3. With the pilot valve 26 shut, fluid pressure in chamber 20 connected to the pilot valve 26 via line 31 builds up to the pressure of fluid at the inlet 4 and the spring 21 biases the control member to the position shown in Fig.1. If the fluid pressure at the inlet becomes greater than the value set by the pilot valve 26, the closure member 30 lifts off its seat to allow fluid to flow to the reservoir via line 32 and the resulting pressure drop across the control member 3 causes it to connect the inlet 4 to the outlet 5. If the pressure drop is sufficiently large to cause the end face 34 to abut the head portion 15 of the housing, pressure once again builds up in chamber 20. The control member 3 moves to establish an equilibrium position. Thus the end face 34 cannot stick in the recess 22 of the head 15.

I.S.O. type corner castings and a larger second engagement member 17 co-axial with the first engagement member 6b and dimensioned for fitting into "Sealand" type corner castings. When the twistlock device is used with an I.S.O. system only the first engagement member projects into the corner casting and, for locking, the said member is rotatable relative to the second engagement member. However, when the twistlock device is used with a "Sealand" system both members project into the corner casting and the members are coupled so that they rotate together for locking engagement with the corner casting of the second engagement member. In the construction shown the shaft 6 is mounted for rotation in a bearing 1 and the second engagement member 17 is mounted slidably thereon, the second engagement member 17 being spring loadably urged towards the first engagement member 6b. The shaft is rotated by a hydraulically actuated linkage, means being provided on the linkage for. the manual actuation thereof (Fig. 2, not shown). A probe 25 cooperates with the members to detect the position of the members when they are used with the different systems the arrangement being such that when the pertinent member has penetrated a sufficient distance into the respective corner casting the probe 25 through a linkage 31, 28, 29 operates a switch to cause the hydraulic actuation to commence and rotate the member through 90. On lifting the container the member moves into engagement with the corner casting this movement allowing the probe to pivot under its spring loading 33 so that the switch cannot be operated during the lifting operation. The shaft and bearing assembly is mounted in a slot in the frame of a load handling spreader so that the assembly can take up a correct position for either system.
