Title: Reset means for coded control
Inventor: BAILEY JOHN WILLIAM
IPC: G07C9/00
Filed: 1964-10-09
Abstract: 1,091,393. Electric selective signalling. A. O. SMITH CORPORATION. Oct. 9, 1964, No. 41371/64. Addition to 967,146. Heading G4H. The invention is a modification of that in the parent Specification. A petrol filling station operative, requiring release of a predetermined amount of petrol from a storage tank at the station, obtains a code setting from the suppliers of the petrol and sets it up by pressing three of ten push-buttons 11 and one of two push-buttons 12, 13. Pushing any pushbutton 11 closes contacts 41 momentarily to step an A.C. stepping switch 8. When the operator has set up the desired code setting he presses " go " button 33. If the code setting agrees with hole positions in a card 15, and at least one of the push-buttons 12, 13 has been pushed, and the right number of push-buttons 11 have been pushed (as counted by A.C. stepping switch 8), a circuit is completed through motor solenoid 3, " go " button 33, contacts 25, 26 controlled by push-buttons 12, 13, A.C. stepping switch 8 and a D.C. stepping switch 9, to energize the motor solenoid 3 thereby closing contacts 4 to energize motor 1 to deliver the petrol. The motor 1 drives a cam 6 to keep contacts 4 closed the required length of time and reset the push-buttons 11, 12, 13. Resetting of the push-buttons 12, 13 is accompanied by closure of contacts 47 to reset the stepping switches 8, 9 through coils 39, 46. However, if the code setting on the push-buttons 11, 12 13 does not agree with that on the card 15, a relay 30 is energized on pressing the " go " button 33 to advance D.C. stepping switch 9 thereby breaking the circuit for the motor solenoid 3 and preventing delivery of petrol, locking-up the system. The stepping switches 8, 9 can also be reset by a key lock switch 49, unlocking the system. Manual resetting means 50 are also provided to reset the push-buttons 11, 12, 13, and the stepping switches 8, 9. Delivery of petrol is accompanied by establishment of a new set of card holes in position. Fig. 4 (not shown) shows an alternative embodiment in which on closure of a switch (82) to its lower position, disagreement between a holed card (89) and code switch setting (90) will open relay contacts (85-1) de-energizing a selflatching relay (83) preventing a load (petrol delivery system) being energized on release of the first switch (82) to its upper position. Said relay contacts (85-1) can be closed again by a key lock switch (93). A mechanical switch interlock is provided to ensure that one or more of said code switches (90) are closed at any one time.

Filed: 1972-09-07
Abstract: 1384133 Screw-and-nut actuators GENERAL MOTORS CORP 7 Sept 1972 [12 Oct 1971] 41491/72 Heading B8J [Also in Division F2] A damped self-restoring stop 30 for arresting relative axial movement between a pair of mechanical elements, such as a screw 12 and nut 22 of a screw-and-nut actuator, Fig. 4, comprises a housing 34, Fig. 5, with end walls 42, 44 rigid respectively with inner and outer walls, and engageable by one of the elements, e.g. the nut 22, after axial movement between the elements, when a shoulder 54, Fig. 4, engages a washer 50 bearing on a slider 40 providing the outer wall 38 of the housing, to collapse the housing by telescoping the slider 40 adout the inner wall (the surface of end 36) to compress at least one (annular) elastic member 58 in the housing; this causes lateral expansion of the elastic member so that not only is there resilient arrest of the relative axial movement and storing of energy for subsequent expansion of the housing but there is frictional engagement of the member 58 with the walls of the housing to dissipate energy and dampen collapse.  As shown, there are a number of spring members 58 of elastically deformable material separated from each other by floating washers 56. The stop 30 described is on the end of the screw shaft 12 but another one, 32, is mounted on an inner sleeve 14 to stop an outer sleeve 16 also bearing a nut adjacent a shoulder 78. Thrust bearings 52, between the washer 50 and a flange 48 on the slider 40 which provides the end wall 44, permit relative rotation of the washer and slider.  In a modified stop, an extra slider (92) surrounded by the elastic spring members (104) and with an out-turned flange (100) at one end, provides the inner wall and one of the end walls of the housing. The flanged end coacts with an inturned flange on a sleeve (120), disposed about the screw and asssociated with the nut on the screw, to stop the movement of the nut away from the end of the screw which bears the sliders.

IPC: C09C1/50
Filed: 1965-09-30
Abstract: In a process for the manufacture of carbon black an electrical charge is imparted to a normally liquid hydrocarbon feedstock immediately prior to its introduction into the pyrolysis zone by contacting the feedstock with a metallic conductor which is maintained at a positive or negative potential of from 1000 to 100,000 v.  When the feedstock is liquid (e.g. residual oil) in the form of an atomized spray the spray nozzle is the charged conductor but when the feedstock is a vapour, it is injected through a pipe within which, near the outlet, are mounted a plurality of charged metallic grids.  The reactor shell is earthed and insulated from the charged conductors by means of a coupling of refractory material such as boron nitride.

Abstract: 1344675 Grippers for lifting paper rolls HAGGLUND & SONER AB 8 Sept 1971 [10 Sept 1970] 41788/71 Heading B8H A lifting device for use with a ship's crane and adapted to grip a pair of paper rolls 4 consists of a pair of jaws 7 each of which is slidable within a housing 8 which is pivotally mounted on a telescopic body 5, 6 and which is provided with an arm 9 connected to a spreader by ropes 22. Further ropes 33 are connected between the spreader and a cam device, Fig. 4 (not shown), within the housing 8, which device alternately causes the jaw 7 to be locked in its operative position, as shown, or to be withdrawn into the housing 8 on consecutively raising the cam device by means of the rope 33. In operation, on lowering the device until stops 21 support the device on a load 4, on subsequently raising the spreader bar, the jaws 7 will be locked in their operative position and the device will be suspended from the ropes 22 causing the jaws 7 to pivot towards each other  to grip the load. On lowering the load on to a support surface and subsequently raising the spreader bar, the cam device is raised by the ropes 33 and thereby retracts the jaw into the housing until a stop is engaged, the lifting device thereafter being suspended by the ropes 33 until the device is lowered on to a further load and the cycle is repeated.  In a second embodiment, Figs. 5, 6 (not shown), the ropes 33 are omitted and the jaw locking mechanism is modified so as to be actuated by means of the arms 9.

Patent GB-424942-A (GB)
Abstract: 424,942. Time switches. DELVINIOTTI, J. T., 5, Avenue du Colonel Bonnet, Paris. Aug. 14, 1934, No. 23483. Convention date, Sept. 5, 1933. [Class 38 (v)] A clockwork actuated switch for closing a circuit at a given time and for a given time comprises a spindle 8 having fixed to it a disc 9 recessed at 16 and a toothed sector 10 provided with a centralizing spring 12. Freely rotatable on the shafts is an insulating disc 17 having an outer ring 18 of metal. The spindle 8 is supported at one end, (not shown), in a frame plate of the clockwork and at the end near the discs 9, 17 in a slot 13 which allows limited movement of the spindle. A lever 4 pivoted at 3 is normally held against a stop 19 by a spring 5. A cam 2 rotatable by the clockwork engages a pin 6 to depress the lever 4 causing a pin 7 on the lever to leave the slot 16 whereupon the spring 12 rotates the spindle 8 to bring the pin 7 against the periphery of disc 9. On further rotation of the cam 2 the pin 6 slips off the swell of the cam and allows the lever 4 to rise due to spring 5, and the pin 7 acts on the disc 9 to lift the spindle 8 so that the ring 18 on the disc 17 bridges contact springs 14, 15 Fig. 4. In this position, a toothed pinion 11 driven by the clockwork meshes with the sector 10 causing the spindle 8 to rotate until the recess 16 is again opposite the pin 7. The spindle then falls, contact is broken and the sector 10 is disengaged from pinion 11 as in Fig. 1. The time during which the circuit is made depends on the distance of the recess 16 from the pin 7 in the position shown in Fig. 4. This can be regulated by moving the point of attachment 20 of the spring 12 to the right or left.
