Title: Improvements in and relating to methods of and mechanism for relieving cutting teethof grooved or fluted tapering workpieces
IPC: B24B3/18
Filed: 1964-01-07
Abstract: 1,049,801. Grinding; taps. HERBERT LINDNER G.m.b.H. UND M.S.O. MASCHINEN-UND SCHLEIFMITTELWERKE A.G. Jan. 7, 1964 [May 14, 1963], No. 759/64. Headings B3D and B3N. A method of relieving cutting teeth in the conical portion of a grooved or fluted workpiece in which corresponding points of the cutting edges lie on a conically extending thread line comprises, during traversing of the tool, such as a grinding wheel, past the workpiece, effecting a feed jump to the radius of the next larger tooth dimensioned according to the conicity and the pitch of the thread line in each instance when the tool is opposite a flute in the workpiece. In apparatus for carrying out the method, the workpiece 5, Figs. 1 and 2, such as a tap, haying flutes 5a is mounted between centres 6 on a headstock 8 and tailstock carried by a slide 2 reciprocatable by a lead screw, not shown. The headstock centre is rotated by a drive 11 from a motor 10 which is also connected by a drive 12 and change gears 13 to a differential 14 having an output shaft 16 mounted in the slide 2, a second drive 15 to the differential being provided for use when the flutes 5a are of spiral form. The shaft 16 is connected by bevel gearing 17, change gears 18 and bevel gearing 19 to a second shaft 20 on which is a cam 21 and a switch-operating cam 22. Cam 21 acts on a follower carried by a cranked lever which is connected by a link to a head carrying a grinding wheel to effect the relieving motion of the grinding wheel on each tooth of the workpiece, and cam 22, when the grinding wheel is opposite a flute, actuates a switch 23 controlling a solenoid-operated valve which is operative to cause a piston-andcylinder device 36 to move a pawl 40 and rotate a ratchet wheel 41 on a shaft 43 connected by gearing 45, 46 to a lead screw 47 engaging a nut 51 on the grinding wheel head, whereby the grinding wheel is fed outwardly relative to the workpiece as the grinding wheel is opposite a flute an amount corresponding to the increase in radius to the next largest tooth. During grinding of the tooth, the cam 21 causes the relieving movement of the wheel head. The lead screw 47 can be moved axially by a piston- and-cylinder device 49, 50 to effect rapid advance of the wheel head, and can be rotated for manual adjustment of the wheel head by a hand wheel 44 on the shaft 43. In an alternative embodiment, the relieving movement of the wheel head is effected by a mechanical drive comprising a driver 52, Fig. 4, from the bevel gearing 19 engaging a star wheel 53 in the shape of a Maltese cross to rotate a shaft 47a in a nut 55, the axial movement of the shaft axially moving the shaft 47 and wheel head.

Title: Yarn Handling Apparatus.
Inventor: DENT GEOFFREY ALAN
IPC: D01H13/18
Filed: 1967-01-06
Abstract: 1,182,181. Dividing by a single blade. CRABTREE INSTRUMENTS Ltd. 19 March, 1968 [6 Jan., 1967], No. 829/67. Heading B3W. [Also in Division D1] A yarn or wire cutter having a base 2 and a cover 17 through which a running yarn 21 can be threaded comprises a cutter blade and preferably two cutter blades 9, 10 movably mounted, e.g., on an arm 4 pivoted at 3. Yarn displacement means such as arms 12 arranged one on each side of arm 4 (see also Figs. 2a, 3, not shown) and pivoted about the axis 3 are associated with the blade, e.g. by means of a spring 14 pulling the arms 12 into engagement with stops 11 mounted on arm 4 and can displace the yarn and grip it against abutment means 16. In operation, control means such as a solenoid 7 connected to arm 4 by a link moves the blades in a cutting direction; thus the arms 12 displace the yarn and grip it against the abutment 16 whereupon it is cut by the blades 9, 10; the cut ends of the yarn still being held. The cutter is described as being used in a draw-twister, the cutter being positioned before the first drawing rollers and operated, e.g. by a yarn detector arranged after the second draw rollers. An adjustable time delay mechanism may be provided to prevent the detector becoming active before the break is repaired. Other yarn detectors which may be provided are:-a transducer type picking up the vibrations of a guide caused by the yarn running through; a feeler bearing on one of the drawing rollers such that when the yarn breaks and an end wraps on the roller, the feeler is lifted to actuate a micro-switch; a photo-electric type sensor. The cutting devices at a number of stations may be linked so that the yarns may be cut in swift succession in readiness for doffing.

Abstract: 728,470. Luminescent materials. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 12, 1953 [Jan. 15, 1952], No. 859/53. Drawings to Specification. Class 39 (1). A luminescent material, particularly for a luminescent screen in a discharge tube, having a luminescence which is stable at room temperature and which has a maximum emission at a wavelength between 6000 Š and 6200 Š is constituted by a fired reaction product consisting solely of Zn, P, Si, O 2  and Mn satisfying the formula xZnO.ySiO 2 .zP 2 O 5 : pMnO, where x: y lies between 2.2: 1 and 1: 1, p : x lies between 1 : 200 and 1: 5 and z : x lies between 1: 400 and 1 : 10. The material can be prepared by heating at a temperature between 700‹ C. and 875‹ C. in a reducing atmosphere containing water vapour, a mixture of ZnO, SiO 2 , MnO, or substances such as carbonates or nitrates from which the oxides can be obtained by heating, and ammonium phosphate. In the specific example described a material having the formula 2ZnO.1SiO 2 .0.03P 2 O 5  : 0.05MnO is prepared by mixing in water 2.03 grs. of ZnO, 0.75 grs. of SiO 2 , 0.15 grs. of MnSiO 3  and 0.15 grs. of (NH 4 ) 2 HPO 4 . The resultant suspension is ground in a ball-mill and dried at a temperature of about 100‹ C. The dry substance is intimately mixed and heated at about 800‹ C. for about 1¢ hours in an atmosphere of steam and hydrogen. Other luminescent materials can be mixed with the material formed.

Title: Brake control system
Inventor: POOLE JOHN DAVID
IPC: B60T13/58
Filed: 1988-11-10
Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.

Abstract: PURPOSE:To simplify and ensure building of the titled pile, by a method wherein a steel pipe is inserted in an excavated hole, and after sediment on a hole bottom is removed, soil cement, formed such that cement is mixed in excavated residual soil, is placed in an excavated hole, located under the steel pipe, through the inside of the steel pipe. CONSTITUTION:After a steel pipe 3 is inserted into an excavated hole 2, sediments at a hole bottom, such as residual soil, is conveyed to the outside of the excavated hole 2. Thereafter, coil cement 4, which is produced such that cement is mixed in excavated residual soil, is placed in the steel pipe 3. This enables disposal of sediment on the hole bottom to be completed in a first process, permits simplification of driving of the pile, and allows for effective utilization of excavated residual soil, resulting in reduction of an amount of disposed waste.
