Abstract: 1,265,550. Alumina-coated silica sol. E.I. DU PONT DE NEMOURS & CO. 16 July, 1969 [18 July, 1968; 9 June, 1969], No. 35918/69. Heading C1A. A positively charged alumina-coated silica sol is made by mixing a negatively-charged aquasol of colloidal silica particles (e.g. 7-30 mÁ. in size) with an aqueous solution of a basic aluminium chloride, aging the sol and then raising the pH of the aged sol to 4À5-6À5 by adding NH 4 OH, an alkali or alkaline earth metal base, e.g. NaOH, KOH, LiOH, Ca(OH) 2  or Mg(OH) 2 , or a water soluble organic base, e.g. methylamine or monoethanolamine or two or more of these. When the aged sol contains 10% or less by wt. of solids, the pH may be raised to 4À5- 7À0. The molar ratio of aluminium to surface SiO a  in the product may be 1 : 2 to 2 : 1. The basic aluminium chloride may be of the formula Al(OH) 2 Cl to Al 3 (OH) 8 Cl, e.g. Al 2 (OH) 5 Cl. Aging may be carried out by allowing the mixture to stand at room temperature, or by heating it at temperatures up to 100‹ C. or, under pressure, above 100‹ C., and is preferably continued till the lowered pH remains constant, generally at 4 or less. Specified aging conditions are about 2 hrs. at 60‹ C., about 30 mins. at 80‹ C. and about 15 mins. at 90‹ C.

Abstract: 1334371 Machine tool control CONSIGLIO NAZIONALE DELLE RICERCHE 5 Nov 1970 52697/70 Heading B3B [Also in Divisions G1 and G3] In a method of controlling a machine tool an electric signal is generated which is representative of the temperature of the region of contact between a cutting tool U and a workpiece P and the vibration of the cutting tool is also detected, and one of the cutting parameters of the machine tool is adjusted to reduce the vibrations when they exceed a predetermined value, and at least one other cutting parameter is adjusted in dependence upon the said electric signal to maintain the said temperature substantially constant at a predetermined value. Apparatus to carry out the said method includes a thermocouple formed by a junction between the cutting tool and the workpiece and including a mercury collector D having a fixed and a rotatable electrode. The said electric signal is produced by the thermoelectric e.m.f. of the thermocouple. The cutting parameters controlled are, the cutting speed which generates the said signal which is fed to a regulator 3 on which an optimum required temperature is set, and which operates through servomotor 4 and hydraulic actuator 5 to continuously control the speed of the machine tool spindle 6; the rate of cutter feed which, if excessive produces vibrations which are sensed by a transducer 7 and fed to a detecting apparatus 9, via an amplifier 8, to operate through a servomotor 10 and actuator 11 to control the cutter feed; the depth of cut by means of a servomotor 15 is actuated dependent on the electrical power consumption of the machine tool; and the overall power consumption of the machine tool is monitored by a wattmeter 12 having a pre-set optimum value and operating through an electric motor 13 and the hydraulic actuator 5 to vary the speed of the spindle 6. A timer device 14 registers the accumulated time a cutting tool U has been in use. For each tool an optimum temperature and useful life is ascertained for setting the parameters.

Title: Tensile member with tension indicator
IPC: G01L5/24
Filed: 1970-08-19
Abstract: 1352327 Tension indicators J V H TRIGG 12 Aug 1971 [19 Aug 1970] 39995/70 Heading F2H [Also in Division G1] To enable the tension of a tensile member 1 to be checked, a pin 3 is movable within an axial bore 2 of the member 1 towards a stop, to urge a bi-stable resilient member 4, e.g. a Belleville spring secured to the pin 3, against a surface 6 of the member 1 remote from the stop. When the member 1 sustains a predetermined tension, it is elongated sufficiently for movement of the pin 3 to the stop to cause the resilient member 4 to snap over from one stable configuration to the other with an audible click. The test pressure to move the pin 3 is applied manually, either directly or via a tool 13. A return spring 8 acts on the pin 3 to restore the resilient member 4 to its first stable configuration when the test pressure is removed. A flexible metal or platics push-button 9 is secured to the outer end of the pin 3 and is force-fitted into a counterbore in the end of the member 1. It has an internal shoulder against which the rim of the resilient member 4 bears during the return movement of the pin 3. As shown, the stop is the bottom of the bore 2. In Fig. 1, the tip of the pin 3 is initially a tubular portion (12) (Fig. 2, not shown) heat-treated to be plastically deformable. With the member 1 loaded to the predetermined tension, a pressure greater than can be applied manually is applied gradually to the pin 3 to deform its tip (12) until the spring 4 just snaps through, the pressure then being relaxed. In Fig. 3, the pin 3 is tubular and has a resilient scroll-section tube 22 pressed into its tip, the required setting pressure being greater than can be applied manually. The calibration procedure is similar to that for the previous embodiment, except that the effect of the gradually applied pressure on the pin 3 forces the tube 22 further into the pin 3. In a modification, a solid-tipped pin 3 co-operates with a volute spring lodged in the bore 2 to form a stop, the calibration procedure determining the position of the volute spring in the bore. In a further modification, a second pin in the bottom of the bore 2 has its point facing the tip of the pin 3 to be jammed in a hole therein, the calibrating pressure acting to force the point of the second pin into the hole in the pin 3.

The toggle comprises links 35 and 37, the former being connected by a pin 34 to the bolt 29 and the latter being connected by a pin 38 to the frame 10 and by a pin 48 to a push-rod 45, having the spring 44 mounted thereon and having its other end slidingly supported in a hole 46 formed in a baffle 47 of the handle 11. When the gun is fired gas passes from the barrel 15 to a pocket 54 in the link 37, via a port 51 in the barrel, a tube 50 and a chamber 52 having an orifice 53 therein. The gas causes the toggle to start to move towards the dotted line shown in Fig. 1 and the residual pressure in the chamber 58 completes the movement of the toggle to its lowest position 60, the spring 44 being compressed by the link 37 and the spring 61 being compressed by the bolt 29. The springs 44, 61 return the toggle and the bolt, the latter collecting a bullet 28 from a magazine 14 in readiness for the next firing of the gun. A bullet may be collected from the magazine prior to the first firing of the gun by releasing the toggle manually using a lever 70 and by moving the bolt manually using a rod 72. The barrel 15 is removable, being held in position by a clamp 20, Fig. 3, which is pivoted to the frame 10 at 21 and is secured to the frame by screws 25, Fig. 1.
