Title: Improvements in or relating to polyethylene blends
IPC: C08F10/00
Filed: 1954-07-28
Abstract: A composition comprising a blend of polyethylene in which the major portion of the unsaturation is branched vinyl and polyethylene in which the major proportion of the unsaturation is trans-internal and/or terminal vinyl, such as that produced in the presence of a composite chromium oxide polymerization catalyst, has improved properties such as higher softening point and better flow characteristics on extrusion.  The latter type of polyethylene which has a high percentage of crystallinity, may be prepared by using a catalyst of chromium oxide admixed with silica or alumina, in a fixed bed or fluidized, at 150-450 DEG  F. and relatively low pressures and purified by precipitation from methylcyclohexane.  The blends may be prepared in solution, e.g. in methylcyclohexane, or by mill or Banbury mixing at a temperature of 200-275 DEG  F.  Examples list the properties of blends of various proportions.  The compositions may be used to form sheets, films or rigid containers.  Specification 790,195 is referred to.

Abstract: 489,410. Measuring distances on maps. THORPE, P. H., and GEOGRAPHIA, Ltd. Aug. 11, 1937, No. 22114. [Class 106 (ii)] [Also in Group XV] Apparatus for measuring distances and indicating routes on maps comprises a map 1 on a panel 2 with a plurality of pegs 4 around which may be led a, string 6 with a terminal piece 11 which can be attached to any of the pegs. The string passes through an aperture 10 in the panel and behind the panel from a device for indicating the length of string drawn out. To measure the distance between two points on the map, the terminal piece 11 is brought from the aperture 10 to one of the points, the reading of the indicator 5 is set to zero (or other suitable figure), the terminal piece 11 then passes around a peg at this point and traces the route round pegs along the selected route and is anchored at the last peg, when the indicator reads the mileage. Setting devices for the indicators are shown in Figs. 8, 9, 11. In Fig. 8, the string 6 is unwound from a drum 7 which can return under the action of a clock spring 39. In a modification this spring can be on one of the spindles geared to the drum. The drum 7 drives a " miles gear 37 which drives a " hundred miles " gear 38 and each of these gears can be pushed out of mesh with the driving gear 33 by a spring pressed button 36 to reset the reading on the indicator. In the device shown in Fig. 9, a. thick gear wheel 42 is supported on a spigot 47a and can be slid axially against a spring 45 by a knob 41. to withdraw a pin 50 on the gear 42 from the drum 7 so disconnecting the drive. By rotating the knob 41, the indicator can be re-set. In a modification, a spring influenced friction clutch may be used for disconnecting the drive. In another modification, the pointer 54, Fig. 11, indicates miles against a scale on the glass 51, while the pointer 55 indicates tens of miles on a scale on the base 53. The indicator is set by rotating the base 53 by means of projections 59, and rotating the glass 51 by the central knob K. A linear indicator is shown on the back of the panel in Fig. 16, in which the initial withdrawal of string is taken up by a slide 90 leaving the indicator at zero. Further withdrawal of string then indicates the mileage on the slide scale 80, the slide 90 being locked.

Abstract: 647,060. Resistance bridges. STANDARD TELEPHONE & CABLES, Ltd., HILL, S. S., ANGLO - IRANIAN OIL CO., Ltd., and RUBACH, A. Aug. 11, 1947, No. 22235. [Class 37] [Also in Groups XXXVIII and XL (c)] An amplifying arrangement for coupling a balanced-to-ground electric signal transmission circuit to an unbalanced circuit comprises a single-valve thermionic amplifier and means therein for preventing the transmission to the unbalanced circuit of random variations of cathode emission. As shown a strain gauge bridge comprises ratio arms R4, R5, and equal strain gauge resistive arms SG1, SG2, one of which is affected by the strain to be measured, a battery being connected between the junction of R4, R5 which is grounded, and the junction of SG1, SG2. The balanced output from the bridge is applied to grids 1 and 4 of the heptode valve, the grids 5, 3, 2 being strapped and connected through a variable resistor R2 to high tension positive. Grid bias is provided by the potential drop in R3 in the cathode circuit and the unbalanced output is taken from anode resistor R1. The potential of the grids 2, 3, 5 may be adjusted by R2, spontaneous increase of cathode current increasing the current to grid 2 and thereby decreasing its potential and the potential of grids 3 and 5, this preventing the tendency to increase of the anode current. In an alternative arrangement, Fig. 3 (not shown), the cathode resistor R3 is replaced by the bridge circuit connected at its D.C. terminals, the junctions of the two gauges being grounded, and the steady space current provides the D.C. source for the bridge, bias for grids 1 and 4 being provided by the potential drops in resistors R4 and R5 respectively.

Abstract: 732,201. Diaphragm valves. GRINNELL CORPORATION. Aug. 14, 1953 [Aug. 28, 1952], No. 22444/53. Class 135. In a valve of the kind in which a flexible diaphragm 12 co-operates with a shallow weir 10b extending transversely across a substantially straight passageway in the valve body 10, undue flexing of the diaphragm is prevented without unduly increasing the area of the diaphragm exposed to line pressure (a) by making the body opening 10e above the weir, the bottom end of the valve bonnet 14, and the diaphragm which is clamped between these parts of saddle-shape with the high parts 12a<SP>1</SP> of the saddle above the longitudinal axis of the valve body and the low parts 12a<SP>11</SP> of the saddle adjacent the ends of the weir, or (b) by making the diaphragm and the co-operating parts of the bonnet and the valve body of oval configuration. Figs. 1 and 7 show the arrangement (a) referred to above. The weir 10b merges into the body passageway which has sockets 10d at its ends to receive pipe ends 11. The flange 14a at the end of the bonnet and the rim of the opening 10e are both downwardly inclined towards the weir at points 10f above the axis of the valve body and become progressively less inclined towards the sides until at points adjacent the ends of the weir they are horizontal. The diaphragm has a bead 12b outside its clamped edge and apertured ears 12c, Fig. 7, adjacent the ends of the weir to receive bolts 16 which pass through mating projections 10c, 14b on the body and bonnet respectively. The bonnet houses the usual compressor 18 connected to a headed stud 28 partly embedded in a boss 12e on the diaphragm. The compressor may have a continuous surface, but preferably has spaced fingers 18a co-operating with a finger plate clamped between the body and the bonnet or with integral bonnet fingers 14d shaped to support the diaphragm in the open position and adapted to prevent rotation of the compressor. The latter is non-rotatably connected to a screwed spindle 20 arranged in a screwed sleeve 22 to which is fixed a hand wheel 24. Figs. 8 and 13 show the arrangement (b) referred to above. In this case the bonnet 14 and its flange 14a, the opening 10e and the diaphragm 12, Fig. 13, are of oval shape and their cooperating parts are in one plane. The two arrangements (a) and (b) may be combined, and thus the valve shown in Figs. 1 and 8 may be modified to accommodate a diaphragm which is both oval and saddle-shaped.
