Title: Improvements in or relating to accumulator mechanisms for calculating machines
Filed: 1945-10-08
Abstract: 600,983. Statistical apparatus. THOMAS, A. Oct. 8, 1945, No. 26189. [Class 106 (i)] Accumulator mechanism for calculating machines, controlled by perforated record cards, comprises a plurality of denominational accumulator wheels, a normally ineffective actuator device to each -wheel, each of which actuator devices.is movable at each machine cycle through a constant distance up to a datum position, and means for disposing a trip member in the path of each actuator in a position in advance of the datum position by an amount representing the digit to be entered into the accumulator. The trip member, on engaging the actuator, serves to render the latter effective to turn the wheel during the remainder of its travel. In the embodiment described the accumulator is controlled by statistical cards which are analyzed by mechanism described in Specification 401,012. The trans. fer mechanism between adjacent accumulator wheels may be of the type described in Specification 560,021. Specification 490,358 is referred to in the Provisional Specification. Movements of the sensing pins are transmitted to rows of pins 25 through Bowden cables in known manner. In each row, the raising of a pin 25, Fig. 3, lifts a member 66 having a protuberance or nose 68 which engages and rocks a lever 61 against the action of a spring 64 and pushes a stop-pin 62 through a hole 65, Fig. 2. For each accumulator wheel 39, a series of pins 62 are arranged in an arc to cooperate with an actuator 44 which, by reciprocating an arm 53, is moved past them during each machine cycle. A protruded stop-pin 62 engages a latch 47 on the actuator, rocking it out of engagement with a block 73 on a pawl 45 and thereby releasing the pawl to engage the teeth of the accumulator wheel 39 under pressure of a spring 72. Thus the actuator drives the accumulator wheel for the remainder of its stroke. To avoid overthrow, when the datum position is reached, a fixed stop 74 momentarily holds the pawl 45 in positive engagement with the accumulator wheel 39 ; a further pawl 75 prevents backward rotation of the wheel. Where none of the stops 62 representing the numbers 1 to 9 or 11 are operated by the sensing mechanism, the latch 47 engages a fixed stop 62a located at the zero position. On the return movement of the actuator the pawl 45 and latch 47 are restored by the engagement of a pin 79 on the pawl with the inturned edge 80a of a member 80. A bar 81, mounted for parallel motion on links 82, 83, is moved by a plate 86 against the pressure of a spring 91 to restore the members 66. According to the Provisional Specification the differential mechanism may control punching or printing mechanism, and electrical sensing means can be employed.

Abstract: 733,313. Tape dispensers. RONNING, L. Oct. 20, 1952 [Oct. 20, 1951], No. 26300/52. Class 18. In an apparatus for delivering predetermined lengths of gummed tape, a roll of tape R is supported on a pair of rolls 2 in a casing 1, or may be supported on a shaft, and is guided between strips 3 and 4. An indicator disc 7 is mounted outside the wall of the casing, and is geared to a strip-feeding wheel 5, the disc being urged by a spring in a clockwise direction and stops 14, 15, limiting its movement. A plurality of holes 7a are arranged around the periphery of the disc 7, and arms 10, 11 provided with pins 8 and 9 respectively, which fit the holes 7a, are pivotally mounted on the shaft 18 of the disc 7. The pins 8 and 9 are of different lengths and co-operate with pivoted stop arms 12 and 13 respectively. The shaft 18 also carries a pivotally mounted lever 17 which at its free end is provided with a knife 16 and is urged by a spring in a clockwise direction to cut the tape when the predetermined length has been withdrawn. A roll 21, carried by a lever 22, pivotally mounted on the shaft 18, co-operates with the strip feeding wheel 5, the lever 17 actuating the lever 22 to move the roll 21 away from the tape when the knife is moved to the cutting position. Attached to the lever 17 is a member' 23 provided with keys 24 and 25, which give a choice of two different lengths of tape. On depressing the key 24 the lever 17 together with the knife 16 will be moved down until the member 23 engages with a notch 13a on the pivoted arm 13, a pin 19 on the lever 17 co-operating with a pin 20 on the disc 7 to rotate the disc 7 and feeding wheel to feed the tape until it can be grasped by the fingers. Upon pulling the tape over the moistening device 28 the disc 7 rotates and feeds a length of tape determined by the position of the pin 9 on the disc 7, and the pin 9 actuates the lever 13 to release the knife and cut the tape. If a shorter length of tape is required the key 25, which is slidably mounted on the member 23, is depressed, and in this position is engaged by a stop member 26 so that the member 23 engages with a notch 12a on the arm 12. When the tape is pulled the shorter pin 8 actuates the arm 12 to release the lever 17 and cause the tape to be cut.

Title: Process and apparatus for decomposing heavy hydrocarbon oils into lighter oils
IPC: C10G9/16
Filed: 1920-09-14
Abstract: 151,925. George, R. D. Sept. 30, 1919, [Convention date]. Hydrocarbons, cracking. - In decomposing heavy hydrocarbon oils to yield lighter oils by heating them under pressure, the free carbon which is formed is continuously removed. The oil is heated in a furnace-heated vertical still 30, containing a rotary scraper 44, and kept normally full of oil. Vapours and oil from the still pass up a pipe 50 to a separating-chamber 14 from which the oil passes by a pipe 54 to an insulated vessel 22 in which the oil rises slowly upwards, and passes through a screen 24. The suspended carbon settles in the vessel or is retained by the screen. The oil returns to the still by a pipe 26. The vapours may be passed from the chamber 14 by a pipe 56 to a chamber 12 in which the temperature is controlled by passing the oil supply through a greater or less length of the coil 10. The heavy oil condensed in chamber 12 is passed by a pipe 60 into the vessel 22 and the vapours pass to a condenser 64. The oil-supply may be pre-heated by passage through the coil 10 and a coil 16 in chamber 14, and is admitted to the vessel 22 by a pipe 18. The bases of the vessel 22 and the still 30 are fitted with blow-off cocks 70, 74 to remove deposited carbon. The circulation of the oil between the still 30, the separator 14 and the carbon-removing vessel 22 may be assisted by a pump. The pressure within the circuit is maintained between 60 and 120 lb. per sq. in., and the temperature between 370‹ and 450‹ C.

Title: Automatic roll stop for textile machinery to prevent damage by foreign material
IPC: D01G15/36
Filed: 1966-06-14
Abstract: 1,133,671. Clutch control. DAVIS & FURBER MACHINE CO. 14 June, 1966 [7 Sept., 1965], No. 26387/66. Headings F2C and F2L. [Also in Division D1] In a carding engine damage to co-operative feed rollers is avoided by driving the rollers via a clutch which slips on attainment of a predetermined torque level which is in excess of that required to pass fibres between the rollers. Preferably the clutch slips before the torque level reaches that required to distort radially disposed teeth on the rollers. If a small piece of electrically conductive material passes between the rollers and contacts them both, the clutch can be completely disengaged. The clutch can be electrically or pneumatically operated. As shown in Fig. 1 distortion of the teeth of the feed rollers 10a and 10b is avoided by the slipping of the clutch 22 when a bulky piece of non-conductive material is presented to the rollers. The disengagement of the clutch is controlled by an electric circuit, see Fig. 5 (not shown), which, when closed by the conductive material bridging the rollers 10a and 10b, deactivates the coil 30 holding the clutch plates together by magnetic attraction. Roller 10b, and licker-in roller 13 which is driven from it via gears 19, are mounted in non-conductive bearings 18 and 17 respectively. In the electrically operated clutch, see Fig. 3, which is a section along 3-3 of Fig. 1, the outer friction discs 34 are held apart by springs 54 but are compressed by pressure plate 36, which moves under the magnetic influence of the coil 30, so as to frictionally engage the inner and outer friction discs 33, 34. The outer friction discs 34 co-operate with rigid fingers 44 extruding from the driving sprocket 24. The inner friction discs 33 have notches (46) which engage teeth 48 on inner sleeve 26, see Fig. 4 (not shown). Sleeve 26 is keyed to shaft 12 by member 28. The electric clutch is disengaged by de-energizing the coil 30. In the pneumatically operated clutch, see Fig. 6 (not shown), the clutch plates are compressed by a piston (102) which can be moved by introducing compressed air through passageway (118). The pneumatic clutch can be disengaged by energizing solenoid valve (114). The predetermined torque at which the clutch slips can be set by adjustment of the current through coil 30 or pressure of air in passageway (118).
