Title: Apparatus for continuously unwinding and splicing web materials
IPC: B65H19/18
Filed: 1966-03-28
Abstract: 1,139,975. Feeding webs. BLACK CLAWSON CO. 28 March, 1966 [29 March, 1965], No. 13643/66. Heading B6B. In a web-roll changing device, the fresh web can be spliced selectively to either side of the running web regardless of the amount of web remaining on the unwinding web-roll. A reel stand 15 has a pair of rotatable spiders 18 axially adjustable to accommodate web rolls of various widths, and a pair of diametrically opposed web-severing means 57 positioned between guide rollers 35 mounted on the arms 34 of the spider 18. The replacement web-roll is accelerated up to speed by one or other of a pair of driving belts 92. Splicing of the running web to the leading edge of the replacement web previously prepared with a perforated adhesive strip, is caused by one of two pressure rollers 25 and 26, which resiliently urges the running web W into engagement with the rotating replacement web-roll 20. To provide clearance for unrestricted rotation of the spiders 18, the two pressure rollers 25, 26 and associated apparatus are mounted between a pair of support members 100, slidably mounted for movement by screwjacks 148, Fig. 6, on adjacent end stands 95. The pressure roller 25 is carried by the forward ends of a pair of horizontally extending arms 110. The rear portion of each arm 110 is pivoted at (111, Figs. 9 and 10) to a block (112) slidably mounted within guide-ways (114) carried by the support member 100. Thus the roller 25 is movable vertically and horizontally with respect to the support member 100. Horizontal movement is controlled by two fluid cylinders (152, 153, Fig. 9) and vertical movement is controlled by a system including a fluid cylinder 120, Fig. 6, connected to the arm 110 through a lever 122 and a cushion pressure cylinder 125. The pressure roller 26 is carried by a pair of arms 130, pivoted to the arms 110, pivotal movement being controlled by a pair of fluid cylinders 135. A guide roller 145 mounted between the arms 110, directs the running web W around pressure roller 25. To splice with the inside surface of the web of the replacement web-roll 20 uppermost, the running web W is urged into engagement with the rotating web-roll 20 as shown in Fig. 1 and (Fig. 11). When the outside surface of the web is required to be uppermost, pressure roller 26 is moved round into engagement with the running web W to urge the same into engagement with the rotating web-roll 20 as shown in Fig. 12. A photo-electric cell 160, Fig. 6, governs the indexing of the reel stand spider 18 to position the web-roll 20 adjacent the splicing apparatus; and a photo-electric cell 161, Fig. 6, scans the rotating web-roll 20 for the leading edge and in response thereto initiates the splicing and cut-off sequence.

Title: Improvements in and relating to electrically controlled locks
IPC: E05B47/00
Filed: 1921-05-17
Abstract: 181,221. Mitchell, E. G., and France, H. May 17, 1921. Electrically-controlled fustenings.-In a lock for railway-carriage doors &c., an electricallycontrolled latch on the door frame is shot by a spring and pushed into withdrawn position by a member rocked by a latch on the door when this latch is manually withdrawn. The door-latch 6, operated by the handle 42, when withdrawn rocks a lever 45 pivoted at 46 to thrust forward a member 47 which pushes the nose of an electricallycontrolled latch 7, sliding on the door frame 1, flush with the door edge, so that the door can be opened. When a projection 14 on the cylinder 12 is engaging the latch 7, both latches 7, 6 are locked against movement. The projection 14 is locked in engagement with the latch by a ball 16 fitting into a groove 13 in the cylinder 12, the ball being retained against movement by the balls 9, 11 and the cylinder 10. To release the lock, the switch 35 is turned to make contact with the terminal on the wire 34, causing the solenoid 31 to be energized, and attracting the armature 28. A prolongation 30 on this engages an arm 22 on the quadrant 21, rocking this to engage the trigger 23 pivoted to the cam 18 and rotating the cam until the gap in it is under the ball 11. The balls 11, 9 and the cylinder 10 then drop, allowing the ball 16 to fall outwards from its engagement with the groove 13 of the cylinder 12. This cylinder is held against gravity by a light spring 17, but the rounded end of the projection 14 and the corresponding depression in the latch 7 permits disengagement of the projection when the latch is operated. The balls 16 and 11 are pre vented from falling out by shoulders. To re-lock the device, the latch 6 is shot by its spring 44, " making " the spring contact 39, 40 and withdrawing the member 47 allowing the latch 7 to shoot under the action of its spring 8. The projection 14 then engages the latch and the contact 39, 40 energizes the solenoid 36, attracting the armature, the end 30 of which engages the pin 20 to rock the cam 18 and force the balls 11, 9 and the cylinder 10 upwards to lock the ball 16 in the groove 13. The circuit may be extended to operate all the doors of a railway train, a thermally-operated switch being incorporated to ensure the release of the latch in case of fire.

Title: Process for the polymerization of propylene
IPC: C07C2/18
Filed: 1950-06-02
Abstract: A feed comprising liquid propylene is contacted with liquid phosphoric acid and esters thereof under polymerizing conditions, the catalyst having a titratable acidity of 95-108 per cent, calculated as orthophosphoric acid, and after heating to about 400 DEG  F. for 5-15 minutes at atmospheric pressure to decompose phosphate esters, an acidity of 100-110 per cent to produce tetramers and higher polymers of propylene boiling above 350 DEG  F. The temperature is preferably 200-350 DEG  F. and pressure 200-2000 p.s.i.g.  Feed rate is above 0.5 vols. of liquid propylene per volume of catalyst per hour.  The mixture of hydrocarbon and catalyst, after leaving the reactor, is stratified, the acid layer recycled, and the hydrocarbon depropanized, and distilled to give a product boiling above 350 DEG F., and an overhead which is recycled.  The minimum necessary ester concentration corresponding to 2 per cent decrease in titratable acidity of an acid of initial concentration 110 per cent is about 5 mol. per cent.  In starting up, 100-110 per cent acid is preferably used and the ester concentration allowed to build up, but propyl esters of phosphoric acid may be added.  The decrease in acidity is maintained below the preferred 7 per cent maximum by reducing the space velocity, raising the reaction temperature or withdrawing a catalyst stream, heating to decompose esters, and returning.  In addition to recycled low polymers, extraneous olefins boiling below 350 DEG  F., e.g. butene polymers or cracked naphtha cuts and especially propylene dimer and trimer, may be added to the feed to raise the ratio of other liquid olefins to liquid propylene to a maximum of about 5 : 1.

Title: Improvements in or relating to systems for connecting automatically alternating current networks in parallel
IPC: H02J3/42
Filed: 1944-07-24
Abstract: 584,323. Electricity supply. MASCHINENFABRIK OERLIKON. July 24, 1944, Nos. 14140 (Convention date, July 24, 1943), 14141, 14142 and 14143, (Convention date, Aug. 2, 1943). [Class 38 (iv)] Synchronizing.-In apparatus for automatically closing the paralleling switch c when the systems a], a2 are correctly phased at a given minimum frequency difference, comprising a device r providing a torque which varies with the relative phase of the systems and which is utilized first to actuate a time delayed relay z at the given frequency difference and then an instantaneously relay m at a point later in the beat cycle and nearer phase coincidence, means are provided whereby the beat frequency and relative phase at which paralleling occurs may be readily adjusted. For this purpose the torque of device r is opposed by two further adjustable torques which determine the points in the beat cycle at which the two relays operate, one of the torques ceasing to be effective upon closure of the time relay and the ratio of' the torque of r to the sum of the opposing torques being adjustable to determine the maximum beat frequency at which relay z can operate. As shown in Fig. 1, device r is a Ferraris disc driven by coils w1, w2 excited by the systems a1, a2 through constant voltage transformers u1, u2. Stops s limit rotation of the disc; which is also opposed by the counter torque of springs f2, f3, acting on a pivoted lever h connected to the disc by a link k. The springs are independently adjustable along the lever to vary the counter torques, whilst a common adjustment e permits variation of the torque ratio. A contact v carried by the lever engages another contact x during part of the heat cycle-as determined by the setting of the springs-and when the period of contact equals the delay time of relay this relay picks up and prepares a circuit for the operating coil of switch c, this circuit being completed and the systems paralleled later in the beat cycle when contacts v, x engage a further contact y to energize relay m. Before this occures the action of spring f3 on the levers is transferred to a stop i, so that the operation of m is dependent only on the adjustment of f2. Relay m is energized from u1 and u2 in series to avoid it closing when the systems a1, a2 are in phase opposition. The counter torques may be produced electromagnetically, instead of by springs, and the torque ratio adjustment may be effected at the link k. Other modifications are described including either means for automatically varying the torque ratio during operation of the apparatus or the provision of a further pair of contacts in the circuit of the operating coil of switch c controlled by an induction disc so operating as adjustably to delay closure of c after relay m has operated.
