Title: Machine tools
IPC: B24B17/10
Filed: 1974-04-10
Abstract: 1499812 Machine tool control system CRANFIELD INSTITUTE OF TECHNOLOGY 9 April 1975 [10 April 1974] 16039/74 Heading G3N A control system controls the position of a tool, e.g. a grinder 22, acting on a rotating workpiece 10, e.g. a cam ring or an external cam, forming part of a fuel injection pump for an internal combustion engine, and compensates for wear of the grinder. The grinder 22 is mounted on the spindle of a grinding head 1 movable at right angles to the cam axis using electric servo controlled motor 2 with tacho 4. Datum sensor 35 defines a data position for head 1 from which grinder movement units are defined by photosensors and the head (wheel) position is sensed by optical linear transducer 5, phase divider 6 and counter 7 to feed one input of comparator 8. The other comparator input receives a desired grinder position from mini computer 18 and the comparator output (difference) is converted to analog in unit 9 and used to reduce the difference. The workpiece 10 is rotated by motor 11 controlled by servo-amplifier 12 using velocity feedback from tacho 13. The angular position of spindle 15 (supporting the cam) is sensed by transducer 16 controlling circuit 17 which compensates for spindle eccentricity. The spindle is advanced rightwards from a rest position, defined by sensor 27, on carriage 26 using servomotor tacho drive 28 and photosensors 29, 30 sense the grinding stroke limits. Sensors 32, 33 are used for grinder dressing with vane 34 and swinging arm 45 carrying tool 46 and sensor 47. The computer 18 holds the desired cam shape data and cam follower 20 measures actual cam profile and feeds it to computer 18. The computer selects the signal to comparator 8 in depedence on the cam angular setting and the machined profile measured by follower 20 and shuts down the machine using logic 24 if the grinder wear exceeds a predetermined limit. A datum face 43 is provided with follower 20, controls 40, 37 and sensors 38-42. D/A converter 25 compensates for velocity lag errors. A computer program for controlling the system Figs. 3-6 (not shown), together with the mathematics of the grinding operation, are described in some detail.

Abstract: 1427904 Fibre-reactive azo dyestuffs BAYER AG 11 April 1974 [12 April 1973] 16122/74 Heading C4P [Also in Division C2] Novel azo dyes of formula (where one Y is H and the other a group-NRZ in which R is an optionally substituted C 1-6  alkyl group and Z is a fibre-reactive group; A denotes the radical of a coupling component) are prepared by reacting the corresponding dyes in which Y is a group-NHR with a compound X-Z where X is a substituent capable of being split off as an anion in the reaction. Alternatively the dyes are produced by diazotization and coupling. The dyes in which Y is a group -NH 2  are prepared by diazotizing 2-amino-1- sulpho-5- or 8-nitro-naphthalene, particularly a mixture of both compounds, and coupling with a compound A-H followed by reduction of the nitro group to amino. The preferred dyes are mixtures derived from the corresponding 5- and 8 - substituted - 1 - sulpho - 2 - amino naphthalenes. The dyes are used for colouring textile materials containing amide or hydroxy groups, particularly wool, silk, polyamide, polyurethane and cellulose.

Abstract: 542,854. Explosives. ZENFTMAN, H. Nov. 6, 1940, No. 16154. [Class 9 (ii)] Moisture in nitrocellulose fibres is replaced by an inert substances solid at normal temperature by mixing an aqueous suspension of nitrocellulose with an emulsion of the inert substance, drying the mixture at a temperature below the melting point of the inert substance and raising the temperature to a point above said melting point so that the molten substance is absorbed by the dried fibres. Suitable inert substances having melting points between 30‹ and 100‹ C. may be chosen from saturated or unsaturated aliphatic hydrocarbons, fatty acids of the oleic series, esters of those acids, derivatives of aromatic hydrocarbons, and non-acid natural products such as paraffin wax, Montana wax, and Ceresine. To avoid formation of dust during the drying operation, the paste may be first compressed into slabs, pellets, or flakes. The final product should contain 80 to 90 parts by weight of nitrocellulose impregnated with 20 to 10 parts of the inert substance.

Title: Improvements in swash-plate mechanism applicable to multicylinder engines
IPC: F16H23/06
Filed: 1923-06-22
Abstract: 200,086. Gerardin, P. G., and Biet, G., (Assignees of Colin, E. L.). June 27, 1922, [Convention date]. Engines with cylinders parallel to main shaft; revolving-cylinder engines; driving-gear.-Relates to swash-plate mechanism for converting reciprocatory into rotary motion or vice versa, applicable to multi-cylinder engines of the type in which the cylinders are disposed around and parallel to a rotary or fixed shaft, and in which the swashplate ring is formed with radial pins connected to the reciprocatory elements through the medium of bearing elements in which the radial pins are adapted to turn and to slide, the bearing elements themselves being also adapted to rotate and to slide transversely in relation to the reciprocatory elements. In the case of one or a pair of diametrically opposite radial pins, sliding movement of the transverse bearing element is suppressed by the provision of thrust bearings. As applied to an internal - combustion engine of two-stroke cycle, hollow pistons P working in cylinders C reciprocate on fixed diaphragms or heads H, fixed in relation to the motor by supporting rods 1 held by cross pins 2 secured to part of the oil-containing casing B, the hollow pistons being slotted at 3 to clear the cross-pins. The swash-plate ring T is mounted upon ball bearings 12 on an internal ring 13 keyed obliquely to the shaft O, being supported laterally through ball bearings 12<a>, by part spherical cups U also keyed to the shaft. Spaced around the periphery of the ring T are radial pins M adapted to turn and to slide in transverse bearing members 15 formed cylindrically so that these in turn are adapted to turn and to slide transversely in sockets formed by the heads or tubular extensions 11 common to each pair of pistons P. In the case of one pair of radial pins M lying on a diameter of the swash-plate ring, endwise sliding of the corresponding transverse bearing members 15 is prevented by end thrust bearings 22 as shown in Fig. 4. In the case of radial pins lying on other diameters of the ring, allowance for endwise movement of the transverse bearings 15 is necessary and these are mounted in the piston heads 11 without thrust bearings as shown in Fig. 4<A>. The slots 3 in the tubular pistons are slightly wider than the pins 2 to allow of the partial rotation of the pistons in the cylinders due to the swash-plate motions. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to pumps, compressors and the like. This subject-matter does not appear in the Specification as accepted.
