Abstract: 1,154,820. Graft polymerization process. MONSANTO CO. 20 Sept., 1967 [21 Sept., 1966], No. 42788/67. Heading C3G. A graft polymer is produced by a process in which reactants comprising a rubbery polymer and a polymerizable formulation graftable thereon are substantially continuously admixed in an inert non-solvent therefor to form a dispersion thereof and the dispersion is subjected to polymerization conditions along a flow path while controlling the exposure of portions of the reactants to polymerization conditions to produce varying degrees of grafting of the polymerizable formulation upon increments of the rubbery polymer and substantially continuously withdrawing from the flowpath a product stream containing graft copolymer dispersed in non-solvent, so that increments of the graft copolymer in the product stream have varying graft ratios. The graft polymer may have a spectrum of graft ratios (weight ratio of superstrate to substrate) of from 1: 10 to 3: 1. The preferred rubbers are diene rubbers, which are grafted with a monovinyl or monovinylidene aromatic monomer, preferably in combination with an unsaturated nitrile. The polymerization may be carried out in aqueous emulsion or suspension, optionally after a prepolymerization reaction carried out in bulk or emulsion. Elongated reactors may be employed, from which portions of the dispersion are withdrawn at a plurality of points after at least partial reaction and combined to form the product stream, or portions of one or more reactants may be introduced at a plurality of points along the flow path, or portions of the product stream may be recycled to a plurality of points along the reaction path. In the examples a butadieneacrylonitrile rubber is grafted in aqueous emulsion with styrene and acrylonitrile. The resulting latices are coagulated and blended with styrene-acrylonitrile copolymer.

Title: Control method for an automatic control centre of a railway system

Filed: 1970-09-11
Abstract: 1318388 Railway control system INTERNATIONAL STANDARD ELECTRIC CORP 11 Sept 1970 [13 Sept 1969] 43538/70 Heading B7N In a control system for a railway network in which a control centre is provided with two computers each of which primarily controls one of the two sub-districts into which the network is divided, the computers are linked so that each can check the feasibility of command instructions issued by the other. The main functions of each computer are maintaining the train movements in its sub-district, determining deviations from a time table schedule and issuing commands to the interlocking (route setting) stations in its sub-district. Maintaining train movements-the computer is initially provided with the entire time table which it stores with the geography of the layout. Information on a train entering the subdistrict is supplied to the computer which mainatins a train list which lists each train and its time table data and a track section list in which details of section occupation are stored. Train end detection-this is carried out by axle counters and the count is transmitted to the computer system where it is compared with train nominal count read into the train list when the train entered the sub district. Where a discrepancy occurs, the count in the next and possibly next but one section is compared with the nominal number and if correct the initial discrepancy is cleared-if not the fault is reported. Route elements-the computer is also supplied with data indicating the state of each element in the network. Route selection-from the positional information of each train the computer determines when the next section of route has to be set. At the required time the computer initiates the setting by determining from the geography of the layout the elements involved and the route defining push buttons. The element numbers are compared with a locking list and if no locking entry is found a first command giving the appropriate interlocking station address and route entry and exit push button is issued. At the same time the second computer is instructed to check the feasibility of the command and if it is satisfied a second similar message is issued. On receipt of the two similar messages the interlocking station actuates the required entry and exit push button relays and the route is set up. After a set time the computers issue an erase message which returns the interlocking push button relays to normal. A signal clear report is the acknowledgement of the executed setting command.

In scissors, shears or pruners in which a pivot pin secured to one of the blades extends through a sleeve secured to the other blade coaxial with the pivotal axis of the blades, the pin and sleeve co-operate to form a bearing whose axial length is a multiple of the thickness, adjacent said axis, of said other blade. In the shears shown in Fig. 1, a pivot pin 11 has a non-circular portion 11c lying within a corresponding aperture in the blade 12 and a sleeve 14 fitting around the stem of the pin has a non-circular portion 14a fitting in a corresponding aperture in the blade 13. The pin has a further non-circular portion 11d over which is fitted a bush 15 having a skirt 15a which embraces a reduced portion 14b of the sleeve 14 with the interposition of a bearing 16. A handle 20 is attached to the bush 15 or skirt 15a whilst another handle 21 is attached to the sleeve 14. A lock washer 18 is keyed to the pin 11 and has peripheral tabs 18a which may be bent upwards into one of a plurality of recesses in a nut 17 the number of tabs differing from the number of recesses so that the nut may be finely adjusted. A peripheral portion of a shoulder 14c of the sleeve is cut back to form a keyway and a portion of the skirt 15a of shorter peripheral length is extended as a key into this keyway so that the angular movement of the blades is correspondingly limited. A spring may be incorporated between the relatively movable parts of the pivot assembly. The blades may be extended rearwardly beyond the pivot and the handles connected directly to the blades. In a modification, Figs. 5 and 7, the pivot pin 11<SP>1</SP> is tubular and is secured to the blade 13<SP>1</SP> whilst the sleeve 14<SP>1</SP> is secured to the blade 12<SP>1</SP>. Handle 20<SP>1</SP> is secured to the sleeve whilst handle 211 extends through a slot 14<SP>1</SP>c in the sleeve and is secured to the pivot pin.
