IPC: B23Q11/00
Filed: 1948-11-08
Abstract: 656,926. Electric indicating systems. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 8, 1948, No. 28979. [Class 40 (i)] [Also in Group XIX] Forces acting on a cutting tool are measured by mounting the tool at the free end of a hollow cantilever and measuring the displacement of the free end in the required direction by means mounted within the cantilever. As shown, Fig. 3, a cantilever tube 3 preferably of steel, extends from a base 1, and at its free end is provided with a jaw 6 and clamping screw 7 for the cutting tool. Deflections of the tool in two directions XX, YY, Fig. 4, are measured by means of corresponding coil pairs 28, 29 and 28<SP>1</SP>, 29<SP>1</SP> disposed diametrally on the central legs of E-shaped magnetic cores 20, 21, 20<SP>1</SP>, 21<SP>1</SP> mounted within the cantilever by end rings 22, 23 and a spacing sleeve 21, and co-operating E-shaped magnetic cores 24, 25, 241, 25<SP>1</SP> mounted on a preferably non-magnetic, e.g. "Inconel" (Registered Trade Mark) hub 26 secured to a column 8 rigid with the base 1. A sleeve 11 secured to base 1 at one end is connected at its other end with the internal surface of the cantilever 3 by a flexible joint comprising, e.g. a rubber ring 12 bonded to metal rings 13, 14 secured respectively to the sleeve 11 and tube 3. The space between the sleeve and tube 3 is filled with oil or other viscous fluid to damp oscillations of the cantilever. Each coil pair is connected in series, with the secondary 30 of a transformer in a separate circuit, Fig. 6. A measuring instrument 32 connected across the mid-point of the transformer secondary and the common point of the measuring coils 28, 29 is adjusted for zero deflection in the absence of any force on the cutting tool and will indicate directly the force in the associated direction XX or YY by the differential displacement effect of the magnetic circuit on the measuring coils. Vibrational forces acting on the tool, e.g. up to 500 cycles per second may be indicated on a cathode-ray tube in lieu of the meter. Condensers 33, 34 provide a capacitative reactance equal to the leakage reactance of the coils to render the instrument scale linear.

Abstract: 479,543. Sliding - clasp fasteners. SUSSKIND, A. Oct. 26. 1936, No. 29020. Convention date. Oct. 24, 1935. [Class 44] Sliding-clasp fasteners of any desired length are produced by cutting off the required length from a long length of a pair of interlocked stringer tapes and thereafter fitting the slider and the top and bottom stops which have projections to give self-locking engagement with the adjacent fastener elements: The top and bottom stops may have plain extension tapes 8, 10 attached as shown in Fig. 1. The top stop 5, Fig. 1, is formed by bending the flat member shown in Fig. 2 ; this form of stop is used with fastener elements of T-shape as the limbs 11<11>, 11<111> of the top stop engage the necks of the adjacent elements. The top stop 6, Fig. 1, is formed by bending the member shown in Fig. 5, this member being provided with spring locking tongues 34 to engage the adjacent fastener elements. The bottom stop 9, Fig. 1, is formed by bending the member shown in Fig. 4. The flanges 31, 32 are staggered so as to correspond with the relative disposition of the fastener elements on the two stringer tapes. The bottom stop is attached while the two tapes are still interlocked. The front and rear faces of the top and bottom stops are held properly spaced apart by means of lugs bent into appropriate recesses. The plain extension tapes are held in the stops by bent over teeth on the remote edges. The top stops shown in Fig. 17 are of angular form so that the plain extension tapes 64 lie parallel when the slider 65 is at the top stops. The bottom stop shown in Fig. 13 has inward projections 54, 55 to lockingly engage the fastener elements and has lateral extensions 56 to prevent unravelling of the tape ends. The plain extension tapes may be stuck to the stringer tapes by adhesive. Specification 449,093 is referred to.

Abstract: 960,270. Centrifugal separators ; nozzles for disseminating gases &c. SIEMENS-SCHUCKERTWERKE A.G. Aug. 11, 1961 [Aug. 25, 1960], No. 29170/61. Addition to 933,225. Headings B2F and B2P. In an apparatus of the kind described in the parent Specification for moving material, the potential flow is set up by the injection of a medium through at least one nozzle provided on its inner surface with asperities, screwthreads or teeth for producing turbulence in the medium. In Fig. 1, air is introduced through a pipe 6 into a nozzle 1 having asperities 4, 2 respectively on its inner outlet surface and on the end of an adjustable plunger 3. The degree of turbulence is increased by the provision of a sharp edge 5 and of vanes 15, the latter imparting a spiral movement to the air. In Fig. 2, an inner turbulent cone 9 is created by the roughened surface of a pointed member 8 which may be provided with an axial bore to produce a third turbulent core. In another embodiment, the air is injected axially through a nozzle in which are mounted two concentric tubular inserts with roughened surfaces and a centrally arranged roughened pointed member. In a further embodiment, a rectangular nozzle is provided with asperities on its inner sides and with guide plates at its outlet end which has a convergent configuration. Turbulence may be further enhanced by blowing in air in a pulsating or intermittent stream.

Title: Improvements in or relating to fluid pressure control valves
Inventor: ADAMS CECIL EDWIN
IPC: G05D16/20
Filed: 1961-08-16
Abstract: 979,015. Electromagnets. BRAKESHOE INTERNATIONAL S.A. Aug. 16, 1961, No. 29522/61. Heading H1P. [Also in Division G3] An electromagnet for loading a pilot valve is disposed in the upper part of the valve housing accommodating a core 61 for the coil 43 of an electromagnet, and a thermistor 44; the core 61 is cupshaped and is provided with a centre post 63. The armature includes a disc 66 with a hollow depending member 68 of non- magnetic material which freely extends through the post 63 whilst the tube 60 is axially slidable within the member 68 and is secured thereto by an adjusting screw 69. The disc 66, member 68, tube 60 and rod 57 are supported against lateral motion by non-magnetic diaphragm 72 having a rim and hub portions connected by curved flexible spokes. A pin 80 prevents rotation of the diaphragm 72, washer 79, and core 61. The air gap between the disc 66 and the poles 62, 63 is made large enough by using a washer 79 so that the forces acting on the armature will remain constant for any given excitation of the coil. The thermistor 44 adjusts the current in accordance with temperature. Operation.-When the electromagnet seats the pilot closure 54 the fluid pressure forces acting in the opposite surfaces of the piston 27 are equal and the main closure is seated by the spring 33; when the -pilot closure 54 allows fluid to enter the chamber 45 from bore 37 the fluid from chamber 45 flows to the port 18 via the external groove in the insert 49, the balancing piston 31 and the bore 30. The coil 43 is permanently excited so that when the fluid pressure in the passage 20, hence in bore 37 has risen sufficiently to unseat the pilot closure 54 against the electromagnetic action of the coil 43, the main closure is unseated due to the pressure drop across the orifice 38 by an amount proportional to that drop; the pilot closure will open to a position wherein the fluid and electromagnetic forces are in balance. The quantity of electricity supplied to the coil 43 is proportional to the pressure which will be maintained in the passage 20; this pressure may be regulated by a potentiometer in the coil supply circuit.

Abstract: 1,130,331. Coated sheet material. LANTOR Ltd. 15 Oct., 1965 [18 July, 1964], No. 29550/64. Heading B2E. A fusible, non-woven bonded fibre fabric is prepared by forming a web of fibres, applying to such webs sufficient of a bonding agent in the form of an aqueous solution, dispersion or emulsion to bond the fibres together and applying to such web, whilst it is still wet and before the bonding agent is fully dried, a thermoplastic resin in the form of fine particles, and heating to dry or dry and cure the bonding agent and to bond particles to the web. The web may be conveyed between wire mesh screens through a bath for bonding agent so that it contains about 1,000% by weight of the liquid, removing one of the screens and applying the powdered resin. The web is then partially dried so as it contains 100 to 200% by weight of the liquid. The drying may be at below or above the fusing point of the particles. In the latter case the fabric may be passed through rollers to flatten the softened particles. The rollers may be heated. Condensable or non-condensable resins may be used, in the latter case catalysts such as an acid, are also used. Suitable bonding agents are acrylic resin or a co-polymer of butadiene with acrylonitrile in aqueous suspension or polyvinyl chloride and a plasticizer in such suspension. Other condensable resin is exemplified a precondensate of a melamine resin with an acid catalyst. Combinations of bonding agents may be used. The thermoplastic resin may have a softening point of between 100‹C and 110‹C. and may be of particle size from 10 to 1,000 microns. 5 grams to 100 grams of resin per square meter of web may be employed. Resins specified are polymers or co-polymers of ethylene, propylene, styrene, acrylic acid esters, vinyl chloride and polyamides such as nylon and polyesters or mixtures thereof. The fibres may be natural, synthetic or mineral fibres such as cotton, wool, rayon, polyamides, polyesters, polyacrylates, glass wool or slag wool of mixtures thereof.
