IPC: B31B7/00
Filed: 1970-01-26
Abstract: 1300141 Making boxes PNEUMATIC SCALE CORP 26 Jan 1970 3663/70 Heading B5D A container forming machine comprises means for intermittently advancing successive container forming sections of a continuous flexible web 14 having adhesive on selected areas thereof, means for intermittently advancing a length of a continuous web of stiffening material 206 into engagement with the upper surface of the flexible web in the idle periods thereof, a pair of rolls for guiding and pressing the webs, means for severing the trailing end of the length of stiffening material and means, for rocking the pressing roll into engagement with the leading end of the stiffening material to adhesively secure the material to the flexible web during the intermittent advance thereof. As shown, the printed web material 14 is withdrawn from a supply roll 6 between a metering roll 18 and a backing roll 20 and is advanced through adhesive-applying mechanism 22, through take up mechanism 24, over a combining roll 66 and between rolls of an intermittently-operated feed mechanism 25, 26, 28 to a severing mechanism 30 from which lengths of web pass to a forming mandrel 10. The lengths of the cut webs are controlled by a photosensitive control unit 34 which co-operates with registration marks (36) on the web, Fig. 4 (not shown). The metering roll 18 is driven through a clutch 112, Fig. 2, which is arranged to rotate the roll 18 through one revolution for each cycle and to permit further feeding movement in each cycle, by means which includes a second clutch 114, the driving member of which is provided with an arm 120 connected by cam-operated linkage 121 which effects rocking of the arm during each cycle. A similar third clutch 140 is arranged to effect an overfeed of the web in response to unit 34. The web of stiffening material 206 is withdrawn from a supply roll 208, Fig. 1, by feed rolls 210, 212 and advances over rolls 218 and 222, the latter being carried by a rockable arm 224. The web 206 then passes between rolls 234, 236 of a feed mechanism 232 to a shearing mechanism 204 which severs a predetermined length of the web 206 which at this time has its leading edge in register with a container forming section 17 of the web 14. Thereafter, the web 14 with the cut off web 206 is intermittently advanced by the feed mechanism 25 and the combining roll 66, to a pressure-applying roll 252 which adheres the cut-off web section 200 to the web 14 which latter is subsequently severed by the mechanism 30 prior to the combined container-forming and stiffening section passing to the mandrel 10. Specification 1,236,491 is referred to.

Abstract: 548,017. Drilling diamonds &c. GENERAL ELECTRIC CO., Ltd., and EDEN, C. G. March 19, 1941, No. 3771. [Class 83 (iii)] Machines for drilling diamonds and for like purposes of the type in which the work and drill are periodically separated during drilling have a fluid link on the feed motion. Either the drill or the diamond holder may be fed, but usually the latter. The diamond holder is mounted on a carriage 1 supported on rollers 2 and linked at 6 to a piston 4 in a chamber 3. A piston 5 constitutes the other member of a fluid link and is operated by a spring 7 and cam 12 reciprocated by a crank pin 13. The crank shaft 9 acts also as a valve to put the chamber 3 into communication with a constant pressure reservoir 8 during the period that drilling is in progress. The relative periods of drilling and separation may be varied by adjusting the cam position by a variable length connecting rod 14. To avoid or reduce impact when the drill and diamond contact, a byepass 24 adjustable at 25 permits slight flow from the reservoir 8 during the separation period. In a modification, a slide valve replaces the rotary valve 9. According to the Provisional Specification the diamond holder may be mounted directly on the piston 4.

Patent GB-1133542-A (GB)
Title: Electronic switching system
IPC: H04Q3/52
Filed: 1967-01-27
Abstract: 1,133,542. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 27 Jan., 1967 [1 Feb., 1966; 11 Feb., 1966], No. 4171/67. Heading H4K. An end-marked self-seeking multi-stage crosspoint switching network reduces the amount of unnecessary cross-point switching involved in setting up a path between line and link circuit by gating only those inlets of the last stage which give access to the wanted link. The network is of the kind described in Specifications 963,319 and 953,895 and uses PNPN crosspoints. In Fig. 6 a set of inlets to the last stage of the switching network can be enabled to participate in the self-seeking process whenever the links to which the inlets give access are marked. If link No. 1 is marked a voltage over diode 71 marks the inlet group over resistors 75-78 while a voltage on column conductor 57 enables the matrix diodes D51-D54. The voltage on the diodes 71-74 is normally clamped by Zener diode 81, but when current is drawn over a resistor 75-78, when a path over the network is established, the diodes 71-74 are back biased to a point at which speech voltages and transients do not interfere. Fig. 9 shows how the switching voltage from the line circuit can be applied from a transistor 90, the response time of which is slowed by capacitor 92. PNPN diodes such as D4 fire in the first stage and the rapid rise of voltage at point, such as 93, fire cross-points such as D04, D51 in successive stages. If cross-point D04 is not available, however, capacitor 94 charges and starves D4 so that it extinguishes and allows another such diode to turn on. A resistor 96 in the output of transistor 90 limits the current drawn so as to prevent spurious switching currents produced if overshoot voltages are present following cross-point switching. Fig. 12 shows a last stage cross-point matrix, the verticals of which give access to links J1-J (n + 4). The stage inlets are grouped in fives, corresponding members of each group giving access to the same group of junctor circuits. For instance, junctors Jl, J6-Jn, are accessible to the first rows of groups 1 to 5. A mark from any junctor of the group J1, J6-Jn, switches a transistor 114 causing diodes 132 to conduct and thereby mark the corresponding inlets in each group. The diode circuits 132-136, with capacitors C5, are individual to each inlet and, except for that circuit illustrated in detail, are shown as RC blocks.

Abstract: 747,382. Printing - machines. SCHNELLPRESSENFABRIK AKT.-GES. Feb. 12, 1954 [Feb. 13, 1953], No. 4264/54. Class 100 (2). Number printing.- In number - printing apparatus in a highspeed cylinder press of the kind having mechanism adapted to be advanced after .each printing operation by a stop on the machine frame, the stop is mounted on the machine frame, in such manner as to be capable of being swung out of the path of a shift rod of the numbering mechanism and said stop is adapted to be brought into and out of an operative position by a control lever governing the printing operation of the machine. The number-printing frame 8 is mounted at one end of a reciprocating frame 7 moving over the machine bed. The shift rod 11 projects from the end of the frame 8 and is designed to engage the stop 9 at the end of each stroke to advance by one unit the numbering mechanisms in the frame. The stop 9 is displaceably mounted on an arm 9b fixed on a shaft 10. Rotatably mounted on shaft 10 is another arm 12 carrying a roller 13 loaded by a spring 14 to engage a cam 15 rotatable by a link 18. This link is connected to the control lever and operated with the inking mechanism when the lever is moved to start the printing operation. An arm 19 fixed to shaft 10 adjacent arm 12 has a sliding pin 20 at one end adapted to be entered in a socket 23, Fig. 4, at the end of arm 12 in order to fix this arm to the shaft so that the stop-carrying arm 9b shall follow the movements of arm 12 transmitted through cam 15. When cam 15 is in the position shown in Fig. 2, the stop lever 9b is rotated to a position in contact with a limit pin 9a which locates the stop 9 in the path of the shift-rod 11. When cam 15 is in the other position the spring 14 rotates the shaft 10 to lift the stop out of the path of shift rod 11 so that the numbering mechanism is not advanced. To enable a new frame to be inserted on a frame carrier 25, Fig. 4, the stop lever 9b is displaceable to the position shown by disconnecting arm 19 from arm 12, by pulling out pin 20, and rotating the shaft through about 180 degrees. In this position it may be secured by entering the pin 20 in a socket 26 in the machine frame and the carrier 25 may then be moved into position without obstruction.
