Title: Take off and stacker for container printing machine
IPC: B65G47/80
Filed: 1972-02-17
Abstract: 1419247 Rotary conveyers J M JACKSON 8 Feb 1973 [17 Feb 1972] 7419/72 Heading B8A [Also in Division B6] Frusto-conical-shaped containers 109 are fed through stations B to F of a printing machine and then released successively at station F to heads 46 of a transfer machine. Stations G to K are inspection and final drying stations. At station L, the containers are released successively to a stack formed in guides 102. The printing machine comprises radially disposed heads 39 (Fig. 5) on which each respective container is held by suction applied along a duct 110. At station F, the suction is released, and compressed air is applied to the duct 110 to blow the container on to a suction head 46. At each station F to L each head 46 is retracted and extended. Each head 46 is mounted on a respective carriage 38 which is radially slidable on slide rod 40, 41. Each carriage 38 has a recess 73 which, at the station F, engages a correspondingly shaped upwardly projecting rib 78 (Fig. 3) of a slide-block 74. During the time interval in which the head 46 is positioned at the station F, the slide block 74 is moved radially outwardly and inwardly in a guide slot 70, formed in a fixed frame cover member 13. There is also a second slide block 75 symmetrically opposed to the block 74 in a respective slot 70. The block 75 engages each carriage 38 when it reaches the station, and causes its outward radial movement on the guide rods 40, 41. The travel of the blocks 74, 75, is produced by means of a cam ring 86 (Fig. 2) rotated from a shaft drive 94 from the printing machine. The cam ring 86 engages follower 84 on the base of the slide block 75. Corresponding movement out in the opposite radial direction, is transmitted from the block 75 to the block 74 by a rack and pinion mechanism 80, 81, 82 (Fig. 4, the rack 81 and pinion 82 also being visible in Fig. 2). Vacuum is broken at station L, and in this way the container is forced by the head 46 through oneway operating spring fingers 105 which hold back the stack on the rods 102. Ribs 72 (Fig. 3) engage the recesses 73 of the carrier 38, to prevent the latter from being displaced by centrifugal force. Vacuum is applied via passages 49 in each head 46 (Fig. 2), and ducts 50, 52, 54, 61 (Fig. 3), during progress through stations F to K. At station L, vacuum is broken by duct 61 (Fig. 3), coming into engagement with an exhaust port 63 leading to atmosphere, by a duct 64. Due to this method of handling, ink on the containers has time to dry between the printing machine and the stack. Also, the printed pattern is uniformly orientated on all the containers received in the stack.

Title: A hydraulically actuated electric switching device
IPC: C07C311/54
Filed: 1957-03-08
Abstract: 838,971. Controllers; control of motors; fluid actuation of switches. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. March 8, 1957 [March 10, 1956; Oct. 18, 1956], No. 7767/57. Classes 38 (3) and 38 (5). [Also in Group XXIX] In a traction or like system, a plurality of heavy-current contacts are each actuated individually by means of a separate hydraulic piston which is, in turn, operated by energizing an electromagnet. As shown, a tappet 5 is coupled by linkage 101 to a movable part of a contact element. A channel 107 supplies oil under pressure to an annular chamber 108 which is connected to a control chamber 110. A control slide 111 comprises iron core 112 which is actuated by electromagnet 11 opposed by spring 115. When the electromagnet is energized (at one of the positions provided on a control drum) the core 112 is moved towards the right so that oil is supplied to the under-side of tappet 5 which is raised as a result, a discharge opening 118 being closed at this time. If, in the further course of the control operation, the electromagnet is de-energized, the control slide is returned by spring 115, the discharge opening 118 is opened, and the contact element is operated in reverse. The oil pressure may be maintained substantially constant by means of an accumulator associated with a spring-loaded piston, or separate small accumulators may be associated with each of the individual contacts. The electromagnets 11 and associated structural elements, together with their control valves, each form a uniform unit, a number of which may be mounted on a common base. The tappets are actuated in a desired sequence by means of the control drum. In a modification, a single electromagnet serves for the control of a plurality of tappets, a first tappet being actuated electromagnetically and, on reaching a predetermined position, allowing access of the oil to other tappets. Thus, when the electromagnet 11 is energized to move the tappet 21 upwardly, a control edge A is raised above a passage 126 whereby oil passes into chamber 129. This chamber is in communication through passages 130, 131, with the space below tappet 22 which is likewise raised and actuates its associated switch. When tappet 22 has completed its upward movement, the passage 128 is opened so that pressure oil enters chamber 134 through passages 126, 128 from whence it is conveyed to other tappets.

Abstract: 241,455. Singer, J. March 23, 1925. Roll-film dark slides. - Relates to feed mechanism for perforated film, of the kind comprising bell-crank claw levers mounted between two reciprocating slides one of which actuates the other in such a manner as to provide lost motion at e,ach end of the travel in order to rock the claw levers into and out of engagement with the film perforations. According to the invention, the lost motion is produced by providing one or more stops on the first slide, engaging one or more slots in the second slide, and each of the bell-crank levers is pivoted at its elbow loosely to the first slide, and at the end of the arm remote from the claw to the second slide. The feed mechanism may be enclosed in a casing carrying the film holders, and may actuate a counting mechanism. The invention is described as applied to a photographic camera, wherein an externally-operable slide 2 moves in a guide in the base 1 of the rear casing, and is connected by a pin 4 to a slide 5 to which are loosely pivoted the elbows of the claw feed levers 13. The short arms of these levers are pivoted to a second slide 6, having a short slot through which the pin 4 passes, thus serving to effect the lost motion between the slides. The film is fed by pulling out the slide 2, and the parts of the feed mechanism are returned to the initial position by a spring 9. A slotted blade-spring 10 presses the slides 5, 6 against guides 11 in the casing. One of the feed claws actuates at the end of the feed stroke a slidable pawl 22 operat. ing the ratchet wheel 23 of a counting mechanism.

Filed: 1942-06-09
Abstract: 555,697. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. June 9, 1.42, No. 7863. Convention date, March 11, 1941. [Class 40 (iv)] A line characterized by a two-digit number is identified with the aid of tens and units groups of discharge tubes. In the tens group, each tube in addition to two main electrodes has ten starting-electrodes connected respectively to the test wires of the ten lines having the corresponding tens digit. In the units group, each tube has ten similar starting electrodes connected respectively to the test wires of the ten lines having the corresponding units digit. When a line calls, its individual relay 110, 111 &c. applies battery to the test wire. Enabling impulses are applied to the cathodes of the respective tens tubes in succession by apparatus 250 and when the turn of the tube corresponding to the tens digit of a calling line is reached, the tube ionizes and the main discharge occurs through the associated relay such as 205. The effect of a high-resistance inductance 208 in the discharge circuits is to raise the potentials of the cathodes of the other tens tubes so that simultaneous calls are ineffective on tubes which receive enabling impulses subsequently. The cathodes of the units tubes also receive enabling impulses in turn but they are not ionized by these impulses and the calling voltage applied by the individual relay alone. When a tens tube breaks down, however, it raises the potential of the test wires of the calling lines connected to it and when a units tube corresponding to one of these receives an enabling impulse, it breaks down and energizes a relay such as 215. As in the tens group, the break-down of one tube prevents the operation of any other. In a modification, Fig. 3, the cathode of each tens tube is connected via resistances such as 306, 308 to the corresponding starting electrodes in the units tubes and provide the extra potential for ionizing the units tube. corresponding to a calling line of which the tube has broken down when it receives the enabling impulse. A resistance 320 may be connected as shown to lower the starting potential applied to the units tubes.

Filed: 1963-02-27
Abstract: 965,519. Rolling. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 27, 1963 [March 30, 1962], No. 7902/63. Heading B3M. A strip thickness control apparatus for a rolling mill comprises means for sensing the presence of a strip between the mill rolls, means for measuring the strip thickness, means for positioning at least one roll in response to the difference between the measured thickness and a reference, and means for resetting one of the rolls, a signal from the strip sensing means permitting operation of the means for roll positioning and operation of the roll resetting means. A radiation gauge 20 measures the thickness of a strip 16 and, if this value differs from a reference thickness, actuates a motor 28 causing a control valve 26 to operate the screw-down 24 of the mill by a piston 22. This sequence only operates if a pressure transducer 34 indicates the presence of the strip 16. Similarly, resetting of the roll gap by a reset piston 64 actuated by a motor operated valve 58 only takes place when the transducer 34 actuates motor driven valves 40, 48, 56 and 68 to perform the above operations.
