Abstract: 1,030,868. Conveying coils. MARSHALL RICHARDS MACHINE CO. Ltd. Sept. 25, 1962 [Sept. 26, 1961], No. 34374/61. Heading B8A. In a wire drawing machine, wire coils fall on to trough 1 at its right-hand end and are progressed leftwards stepwise by pivoted pushers 16 which reciprocate, the pushers being folded back on the return movement, the coils are dicharged from trough 1 on to lift 6 which lifts them up to trough 2. The coils are thus taken from lift 6 and moved step-by-step along trough 2 rightwards by reciprocating pushers 16c, which push on the forward movement and pivot inoperatively on the backward movement. Pusher 16, Figs. 2 and 3 (not shown).-Each finger 16 pivots around a shaft 26 carried by a carriage 12 which runs on rollers 25, each finger forming part of a wheel 15 and the wheels 15 being connected together by rope 17 which passes round and is fixed to each wheel 15, the ends of rope 17 passing round two drums. When rope 17 is pulled by a drum to the right, finger 16 is first elevated to the erect position and then moves rightwards in order to convey; but when the rope 17 is pulled to the left by the other drum, wheel 15 moves to cause finger 16 to pivot downwards into the inoperative position and then moves leftwards inoperatively.

Abstract: 1,059,716. Spindle brakes. ZINSERTEXTILMASCHINEN G.m.b.H. Aug. 11, 1965 [Sept. 1, 1964], No. 34392/65. Heading F2E. A spindle brake wherein an integrally formed drum or disc on the spindle is engaged by external or internal shoes or by axially movable pads or a friction disc, is applied by supplying air or hydraulic fluid under pressure to a cavity which is formed partly by an annular or partannular rigid member and partly by an elastically deformable partition which is arranged to close the cavity in sealing manner. In the form shown in Fig. 1, the partition 20 is of U- section and is clamped between annular top and bottom plates 25, 8 of a housing 9, via an intermediate ring 22, the ring 22 and housing 9 being bored at 28 for the supply of fluid to the cavity thus formed, whereby the partition urges a pair of shoes 15 pivoted at (16) (Fig. 2, not shown) to the base 8 to engage drum 12 formed integrally on the spindle 10, against the force of a release spring (19) arranged between the free ends of the shoes. In Figs. 1 and (2), the partition is part-annular, but Fig. 3 (not shown) discloses a partition extending entirely around the shoe assembly. The edges of the portion may be beaded (Fig. 4, not shown) and engage in grooves in a modified ring (23) to improve sealing. Ribs on the partition may similarly engage in grooves in the top and bottom plates (25), (8). The partition may be flat (Figs. 5 and 6, not shown) in which case it is clamped to the edges of the plates (25), (8) by an encircling member which can be tightened into sealing engagement with the partition and in which the fluid inlet is provided, the ring 22 being omitted. In a further embodiment (Fig. 7, not shown) pads (74), (75) arranged over part or all of the circumference of a disc (80), formed integrally on the spindle, are urged axially to engage the disc by opposed annular or part-annular fluid pressure chambers (57), (58) formed by upper and lower housing plates (55), (56), an intermediate ring (70), and partitions (60), (61) clamped at their outer edges between the plates and the ring, and clamped at their inner edges between the plates and rings (64), (65). The pads are secured to the partitions so obviating the need for return springs. The shoes in the earlier embodiments may also be secured to the partition.

Abstract: 1275268 Tunnel linings WILLIAM F REES Ltd D F REES and J B GARNETT 30 June 1970 [11 July 1969] 35088/69 Heading E1F A method of lining a tunnel comprises using radially flexible rings, or rings having radially flexible major segments, passing the rings or major segments through an installed tunnel lining, flexibly expanding the rings or major segments to conform with the tunnel lining and, in the case of a major segment, inserting a minor segment to complete the ring. In one described method a flexible split ring 14, Fig. 2, is held contracted by steel bands 16 to enable the ring to be passed lengthwise through lining 11. Alternatively, Fig. 3, flexible complete ring 20 is deformed by jack 21 to enable it to be passed sideways through the lining. In a further described method, Fig. 5, major flexible ring segments 30a are held contracted by steel bands 32. Rigid minor segments 31, which may be of concrete to form an invert, are inserted after segments 30a have been expanded. The expanded segments are moved to abut the installed lining by the tunnelling shield rams. Mild steel segments may be used, whose joints may be welded. Sections made of resin-bonded materials, or plastics such as unplasticised P.V.C., may be used, and their joints may be bonded. Longitudinal joints may be sealed with joint strip 17, Fig. 2. Circumferential joints may be of the spigot and socket type, and may be bonded or fitted with rubber O rings.

Class 79(1) [Also in Groups XXIX and XXXIV] In a braking system (Group XXXIV) in a trailer adapted to be hitched to a tractor having a driver-operated hydraulic power lift, spring applied brakes on the trailer are released by an hydraulic brake ram adapted to be connected to the tractor hydraulic power lift system to receive pressurized fluid from the system under the control of the hand lever of the tractor hydraulic power lift. In the diagrammatic view shown in Fig. 1 the tractor hydraulic power lift device is shown in its "lift" position and the hydraulic system of the power lift includes a pump 11 having a suction conduit 12 and a delivery conduit 13 connected to the main hydraulic rain 14 of the tractor. A hand lever (not shown) within reach of the tractor driver actuates valve 16 to control suction conduit 12 and discharge conduit 15 leading to a sump. In the brake released position shown, oil is being discharged from the pump 11 through delivery conduit 13 to the main hydraulic ram of the tractor and through supply conduit 30 to the brake ram cylinder 32 to force brake piston 33 to the left; the oil flowing through return conduit 31 to the oil sump. When the driver of the tractor hitches the trailer in the normal way by raising lower hitch links 20 (Fig. 9) and then moving hand lever 41A to bring valve 16 to the "drop" position so that the trailer is supported on the latch mechanism. Conduits 30 and 31 are then connected to the delivery conduit 13 and tractor sump respectively and the hand lever is then raised to open the conduit 12 so that oil is supplied to brake ram cylinder 32 to move piston 33 to the left as shown in Fig. 1 against the action of brake applying spring 38.

Title: Chemically modified polymers of 1,2-alkylenimines and a process for their production
Inventor: SOENKSEN UWE
IPC: C08G73/04
Filed: 1965-08-20
Abstract: Water-soluble polymers of (a) 1,2-alkylene imines which do not bear any substituents on the nitrogen atom with (b) a ,b -unsaturated carboxylic acids or their acid chlorides, esters or anhydrides, are prepared by reacting 1 mole of (a) in solution in water or in an organic solvent containing water with 0.001 to 0.5 moles of (b) with the viscosity of a 1% by weight aqueous solution of the reaction product is at least 1.2 centipoises at 20 DEG  C.  The reaction is preferably carried out by placing the bulk of (b) in water or a mixture of water and an organic solvent and then allowing (a) dissolved in water to flow in at 70 DEG  to 100 DEG  C. or by allowing the reactants to flow simultaneously into the solvent which has been previously heated.  The examples describe the reactions of ethylene imine with methyl acrylate and with maleic anhydride.ALSO:Cellulose fibres for use in the paper industry are treated with water-soluble polymers formed by reaching a 1, 2-alkylene imine with an a , b -unsaturated carboxylic acid or its acid chloride, ester or anhydride until the viscocity of a 1% aqueous solution of the reaction product is at least 1.2 centipoises at 20 DEG C.  The fibres may be of bleached or unbleached sulphite cellulose. Example 2 describes the treating of unbleached sulphite cellulose fibres with a polymer prepared from ethylene imine and methyl acrylate.  The polymers increase the freeness of the pulp and the wet-strength of the paper.
