Filed: 1976-10-06
Abstract: 1525538 Flow measurement ROBERT BOSCH GmbH 6 Oct 1976 [7 Oct 1975] 41511/76 Headings G1N and G1R [ Also in Division F1] An air-flow meter, for a fuel injection system of an I.C. engine, comprises a flap 30 on a spindle 51 rotatable against a coiled spring 65 which engages a cam 70 on the spindle; a housing 67 for spring 65 which can rotate coaxially with the spindle and to which the outer end of spring 65 is secured and a locking spring 120 which engages the meter housing and a toothed rim 75 of the spring housing. The spring 65 can be tightened without removing spring 120. A damper 47, a counter weight 79 and sliding contact 81 are rigidly attached to the spindle 51 to rotate with flap 30. Contact 81 moves over a resistance track (84), Fig. 2 (not shown) to provide a variable resistance. Initial rotation of the flap operates a pair of contacts. The flap includes a relief valve 110 .. 112. The contour 44, Fig. 4, is such that the air gap cross-section increases exponentially as the flap rotates. The meter is used in a circuit for operating four e.m. fuel injection valves of an I.C. engine and is placed upstream of a butterfly valve adjusted by the accelerator pedal.

The type characters are formed on the studs 18 by rolling a drum, bearing the desired characters on its surface, over the surface of the blanks whereupon each blank 17 is cut to a length of 750À72 mm. and the blank ends welded together to form an endless belt. The belt may be heated at 480‹ C. for 3 hrs., and its surface hardened by bombarding it with glass balls. After cutting out slots 25 in the belt, the latter is cut along the line 27 to form the tongues spaced apart by 3À91 mm. A damping strip 28 may be positioned below the level of the type characters on one or both sides of the tongues.

Abstract: 1,009,668. Moulded concrete. YAWATA IRON & STEEL CO. Dec. 4, 1961, No. 43284/61. Heading B5A. A method of manufacturing pressed concrete comprises pouring concrete into a moulding box in which reinforcing material is arranged, vibrating the box, pressing the concrete first at about 10 kg./cm.<SP>2</SP> for a short time and secondly at 20 kg./cm.<SP>2</SP>, and then curing the concrete while in the compressed state in steam. Iron or steel bars are welded or jointed together and are placed in an easily assembled and disassembled moulding box. The concrete is so mixed and kneaded that it easily flows through the reinforcement and into the corners of the box. The preparatory pressing is to enable the pressure distribution to be uniform for the high pressure and to allow water to separate from the concrete. The pressure is applied to the lid 9 of the box by means of cotters 6, hydraulic pressure cylinders 3 on either side of the mould, switching valve 15, pressure regulating valve 14, accumulator 17 and pump 16. The common pressure supply system to the various cylinders 3 allows a uniform pressure to be applied to the mould. The high pressure is applied for 6-8 minutes before the pressure in cylinders 3 is released. The box together with frames 5 and cotters 6 is put in a steam curing chamber for about 2¢ hours. Finally the concrete is removed from the box and cured in water.

Title: Manufacture of fine count fabric from spun synthetic fibres
Inventor: SUBRAMANIAM THIRUNELLAI ANANTR
IPC: D06Q1/02
Filed: 1965-10-19
Abstract: A fabric is made from synthetic fibres by a process comprising (1) blending polyester, polyamide, polyacrylic or other synthetic fibre with cotton, viscose rayon, polynosic fibres or other cellulosic fibres which can jointly share with the synthetic fibres the tensile stresses imposed during spinning, winding, warping and weaving operations as normally done, (2) preparing a woven fabric from the blended fibres and (3) removing the cellulosic fibres from the fabric by carbonizing it.  The resulting fabric may have spun yarn counts as fine as 12os count (English System) or even much finer than this. The carbonizing may be effected by treating the fabric with an aqueous solution of aluminium chloride, aluminium sulphate or stannous chloride, drying it and baking it at a temperature over 100 DEG C for 1-10 minutes.  Carbonization may be effected until all the cellulosic fibres has been carbonized or until 5-8% by weight of the cellulosic fibre remains.  The fabric may then be rinsed with water, boiled in a solution containing 0.5 gms/litre of soap or another detergent with sufficient agitation to remove the carbonized material from the fabric, bleached and thermoset.  The proportion of cellulosic fibre in the fibre blend may be adjusted according to the count desired in the final fabric.  The carbonizing agent may be mixed with an acid resistant thickener and printed upon the fabric in localized areas and the fabric then carbonized to obtain a finer texture in the localized areas.
