Abstract: 1322575 I.C. engine fuel injectors ROTODIESEL 9 Sept 1970 [15 Sept 1969] 43119/70 Heading F1B [Also in Division H1] The magnet core of a fuel injector is formed of grain-orientated laminations 2 of E-shape clamped at one end within a hole in a non- magnetic disc 5 so that one end face of the core is flush with the face of the disc which faces the armature 26 on the valve needle 20. The laminations 2 are clamped intermediate the ends of the core by non-magnetic strips 3, located in the recesses between the core limbs, having curved ends (4), Fig. 2 (not shown), engaging opposite core sides. A winding 7 on the central limb of the core is soldered to the ends 9a of electrical connectors 9 in a member 8 of insulating material. The bore 12a of a fuel inlet union 12 conveys fuel to a U-shaped tube 13 through an aperture 13a and the ends of the tube are located in holes in the disc 5. The core and member 8 are sealed in the injector body 1 by an epoxy resin which is injected through a hole 18 in the body and passes through bores (10), Fig.6 (not shown), in the member 8 to a vent 19. The armature laminations extend between side flanges (27b), Fig. 9 (not shown) on the needle head 27 and spaces defined between depending end portions 26a of the laminations and grooves 27a in the head are filled with plastics material to bond the laminations to the head. A ring 29 between the disc 5 and the nozzle body 21 determines the lift of the needle 20 and supports a pair of wire springs 28 which engage shoulders (27c) on the flanges (27b) to bias the needle 20 onto its seat 21a.

Abstract: 1304798 Internal pipe support NIPPON KOKAN KK 16 Sept 1971 [29 Sept 1970] 43174/71 Heading F2P Large pipes (e.g. of steel) are supported against deformation when stacked or transported by internal cross braces 1a-1b secured together at their mid points by nails 3. Each brace has a foot 4 secured to one end, the foot being profiled at 8 to complement the curvature of the pipe. The ends of the braces opposite feet 4 have feet 9 adapted to slide within a slot 10 (cf. Fig. 6). Wedges 13 may be driven between the braces and feet 9 to tighten the support within the pipe, the surface 12 of each foot 9 once again conforming to the curve of the pipe. As shown in Fig. 5 two further braces 1c are also used, one end 15 of each brace being shaped to fit the obtuse angle between braces 1a and 1b, and the other end of each brace being adapted to receive a foot 9 and wedges 13. When pipes bearing the above mentioned braces are stacked the points of contact of the peripheries of the pipes coincide with the position of a foot (4 or 9) at the end of a brace (Fig. 7, not shown). The braces 1c, 1c may be replaced by a third brace which has no common point of intersection with the braces 1a, 1b.

In the construction shown the retaining means is an elongate loop formed from a length of steel piano wire which is connected to a block 5 which is retained in the bore of the member 1 by a pin 6 extending diametrically through the member 1 and the block. The retaining means extends into the bore of the inner tubular member 2 and is crimped near its forward end to form a spring clip portion 7 and crimped near its rearward end to form a spring clip portion 8 each to engage the locating means which as shown is a pin 3 near one end of the member 2. In a modification the retaining means instead of being a wire loop can consist of a support element with spring clips spaced apart along its length. The outer member can be the pole of a stretcher and the inner a handle of the stretcher.

Stable organosols are prepared by polymerizing chloroprene, optionally with 2,3-dichlorobutadiene as comonomer, in an organic liquid which is a non-solvent for homopolymers of the monomers, and in the presence of (1) a polymerization initiator, and (2) a graft copolymer of a C 6-12  alkyl ester of methacrylic acid and solid polychloroprene of M.W. 250,000-600,000, the alkyl ester being 40-70 wt. per cent of the graft copolymer. In examples, the organic liquid in hexane, the initiator is azobis-(isovaleronitrile) or t-butylperoxypivalate/iron naphthenate, and the reactants are usually added dropwise to the hexane over an extended period. The organosols may be used in adhesives. Graft copolymers of 2-ethylhexyl methacrylate on solid polychloroprene are prepared by dropwise addition (over 3 hours) of azobis-(isobutyronitrile) in benzene to a benzene solution of reactants, and reacting for a further 17 hours.

Title: High precision pressure standard
IPC: G01L27/00
Filed: 1960-12-30
Abstract: 928,422. Pressure transducers. ROSEMOUNT ENGINEERING CO. Dec. 30, 1960 [Jan. 12, 1960], No. 44867/60. Class 40 (1). [Also in Group XIX] A pressure standard for indicating when an applied pressure reaches a predetermined value comprises a diaphragm marginally sealed between a sealed space containing gas and a chamber having a passage for the application of pressure and means responsive to deflection of the diagram by a specified amount to provide a signal indicating such deflection. As shown in Fig. 1 a radially-stressed diaphragm 12 (for example, having concentric corrugations) is welded at its margins between a thick disc 11 having a central inlet passage 18, and a cupshaped member 10. The base 10B of the latter is thin and made slightly concave by the application of a high pressure via the inlet 18 to push the central region of the resilient diaphragm 12 against the said base 10B. Alternatively the concavity could be formed by machining. A wire 20 lying in a groove in the base and fixed at one end 20C has a kink 20A bearing against the diaphragm. When a source of adjustable pressure is applied to the diaphragm via inlet 18 and filter 15, deflection of the diaphragm will move wire 20 until at a predetermined pressure the latter touches a wire 21 to complete a circuit and provide a signal. The spacing of wires 20 and 21 can be adjusted by screw 22 to a position known from experience to be approximately correct for a pressure of given magnitude. The diaphragm 12 itself may form the contact for closing the signal circuit; or, it may form one plate of a condenser the variation of capacitance due to a specified amount of movement providing the signal. As shown in Fig. 15 the second plate is a disc 181 on rod 121 insulated from screw 180, which extends to the exterior to facilitate adjustment and houses an insulated tube 183 forming a guard shield for disc 181. Changes in capacitance thus involve only the disc 181 and are preferably observed using a 3-terminal transformer coupled ratio-arm bridge. The diaphragm may lie between two cup-shaped members with concave bottom, movement of the diaphragm either way (i.e. for a high and a low pressure) causing closure of contacts to produce a signal.

Title: Improved Electromagnetic Actuator

Filed: 1966-10-07
Abstract: 1,156,632. Electromagnets. AMBAC INDUSTRIES, Inc. 7 Oct., 1966 [12 Nov., 1965; 8 Aug., 1966], No. 44872/66. Heading H1P. In an electromagnetic actuator suitable for use in controlling the speed of an internal combustion engine, comprising a stator with an energizing winding and a pivoted armature which is attracted towards the stator to an extent determined by the current in the winding the rotational force for a given current is substantially independent of the position of the armature over a considerable range of its movement. In the preferred device (Fig. 4) the laminated U-shaped core of the stator has arcuate portions coaxial with the armature pivot co-operating with similar acruate portions formed on prongs 74, 76 extending from the main part of the armature. In operation, since the magnetic flux travels radially across the constant air gap between these co-operating portions, the torque exerted on the armature is due solely to edge effects and remains substantially constant. The armature is attached to one arm 44 of a hinge which is riveted to a PTFE coated glass fibre strip 48 attached to the stator casing, the arm forming a knife edge bearing on the fixed part of the hinge. Armature movement is controlled by springs 66 and limited by stops 60, 68 and the air gap is made adjustable by making the clearance holes in hinge 50 larger than the securing bolts 56. In a modified arrangement the armature is centrally pivoted and has shaped prongs at both ends co-operating with two separate stator assemblies
