Title: Improvements in jet impact pulverizers
IPC: B02C19/06
Filed: 1931-07-10
Abstract: 381,605. Jet-impact pulverizers. ANGER, P., 59A, Beselerallee, Kiel, Germany. July 10, 1931, No. 19901. [Class 59.] In a jet-impact pulverizer means is provided for discharging tramp metal and other undesired material through the jet nozzle. Material is fed to a chamber 1 through an orifice 2 and is carried through a tube 4 by a blast and is disintegrated against an impact plate 5, the fine material being carried off through an outlet 6. The blast enters the chamber through a pipe 12 and orifice 3 and a discharge receptacle 7 is formed below the nozzle for the reception of heavy particles &c. which fall therein when the blast is shut off. The bottom of the receptacle may be closed by a single or double sliding valves 10, 11 or a rotary valve may be used. A pipe 14 and valve 13 may byepass the nozzle so that when the valve is opened the contents of the pulverizer fall into the receptacle. In a modification a valve opening either inwardly or outwardly of the pipe 12 may be placed between the pipe 12 and receptacle 7.

Abstract: 635,374. Tailstocks. BARBER-COLMAN CO. July 29, 1947. No. 20410. Convention date, July 3, 1940. [Class 83(iii)] A tailstock clamping device comprises a member rotatable to adjust the position of the tailstock, a driving connection between this member and means for shifting the tailstock disengageable at any point in the range of tailstock movement, and clamping means operable by rotation of the member when the driving connection has been disengaged. The tailstock 20 carrying a centre 21 is slidable along the ways 16 of a metal-cutting machine. A rack 24 secured to the machine is engaged by a pinion 25 loosely mounted on a shaft 27 within the tailstock body. Wedge faces 41 and clutch recesses 40 are provided on a sleeve 39 integral with the pinion. Rounded complementary clutch teeth 44 are provided on an adjacent sleeve 43-which is pinned at 42 to rotate with the shaft 27. Coaxial with and in abutting relation to this sleeve a headed member 45 is arranged having flat side faces which pass through a rectangular opening in a transverse member 52 having a clamping wedge 19a at one end. The headed member 45 is maintained against the sleeve 43 by a compression spring 49. A wedge face 59 on the headed member engages a complementary wedge-piece 56 located within the transverse member to effect the clamping action. The single control lever 17 is pivoted at 35 in a rotatable but axially-held sleeve 29 so as to be rotatable in two planes at right angles. The end 36 of the lever 17 opposite the handle engages in a slot in the shaft 27. Operation.-By first rotating the handle clockwise (looking upwardly in the Figure) the teeth or projections on the sleeve 44 are brought into register with the recesses 40, and the wedge faces 57, 58 are freed. Continued rotation of the lever in either clockwise or anticlockwise direction adjusts the tailstock along the machine ways. When the final position with the centre engaging the work is reached, the tailstock is clamped by moving the handle at right angles in a direction towards the tailstock to compress the spring 49 and then by turning it anticlockwise to move the projections 44 up the cam faces 41 so drawing up the wedge member 19a through the engagement of the wedge faces 57, 58.

Title: Improvements in or relating to methods and apparatus for measuring the dimensions and/or displacement of objects without making contact with the objects and, in particular, for measuring the width and/or lateral displacement of travelling strip material
IPC: G01B11/04
Filed: 1955-07-19
Abstract: 810,982. Gauging by photo-electric devices. EXATEST GESELLSCHAFT FUR MESSTECHNIK. July 19, 1955 [July 19, 1954; Oct. 27, 1954], No. 20932/55. Addition to 787,385, [Group XIX]. Class 40 (3). In a method of gauging the width and/or parallel displacement of an object, particularly strip material as in the parent Specification, the images of the edges a, b of the object 1 are produced by television cameras 2, 3 and shown on a single receiver 4. By positioning one camera, as shown, at an angle y, the images a 1 , b 1  on the screen are made to intersect one another. In the arrangement shown, Fig. 9, the images move from a 1 , b 1  to a<SP>1</SP>, b<SP>1</SP> for a change in width d, their point of intersection moving from s to s<SP>1</SP> along the bi-sector W of the angle # on the screen and as shown in Fig. 10, for a parallel displacement p of the strip from X to X<SP>1</SP> without a change of width, the images move a distance p<SP>1</SP> from a<SP>1</SP>, b 1  to a<SP>1</SP> 1 , b<SP>1</SP> 1 , their point of intersection moving from s to s<SP>1</SP> along the normal n to the bi-sector W. By keeping the angle # small, e.g. 8-10 degrees, the distance s, S<SP>1</SP> for a change of width may be made e.g. seventeen times greater than the distance s, S<SP>1</SP> for a corresponding parallel displacement of the strip. By selecting an electro-optical transmission ratio for the image height differing from that selected for the image width this magnification of the width image displacement may be increased. The lower image diagrams in Figs. 9, 10 show such an alteration. Preferably in this case the two cameras are turned relatively to the strip axis through an angle #/2, Figs. 11, 12 whereupon the movement of the intersection of the image for a width alteration will be normal to the movement of the image for a parallel strip displacement, even with differing electro-optical transmission ratios for image width and height. The receiver screen may be orientated as in Fig. 17 so that the directions of the bi-sector W and the normal n thereto coincide with the directions of the rectangular axes of the screen, a scale 8 being provided to measure the movement of the image intersection point along the bi-sector. In this arrangement pure parallel displacement of the strip without any change in width result.only in a lateral displacement of the triangular area 7 in the direction of the double arrow 9, the apex moving parallel to the vertical axis of the screen for changes in width of the strip. Such width changes may be measured by photo-electric elements 10, Fig. 18, fitted on the image screen 4 and connected by an amplifier 11 to an indicator 12.
