A beater mill includes beater blades 10, 25 disposed in two or more coaxial rings lying side-by-side and a beater wheel 6 on which the blades are mounted and arranged to rotate about their common axis, the material being supplied to one side of the beater wheel in a general axial direction and discharged outwardly between the beater blades, partly between the blades of one ring and partly between the blades of the, or each, other ring. The wheel 6 rotates on a shaft 4 in a housing 1 having a discharge branch 3, material being delivered through an opening 2 at the lower end of a charge shoot 35 after partial reduction by beater-arms 36, 37. The wheel includes a circular rear wall 7 and two flat annuli 9, 24, annulus 9 being connected to the wall 7 by struts 8 and annulus 24 being connected to the annulus 9 by struts 23. The blades 10 in the ring nearer the wall 7 are similar to each other and have their outer edges parallel to the axis of rotation of the wheel, whilst their inner edges are inclined to the axis. All the blades 25 in the other ring are also similar to each other, their outer and inner edges being parallel to the axis of rotation of the wheel. The blades 10, 25 are prevented from radially outward movement during rotation of the wheel by contact between the outer edge of the blades 10 and flanges 11, 12, formed on the disc 7 and ring 9 respectively, and between the outer edges of blades 25 and flanges 26, 27 formed on rings 9, 24 respectively. Each of the opposite side edges of blades 10, 25 is bent away from the strut supporting the blade. The edges 14, 29 of blades 10, 25 abut wear plates 19, 34, Fig. 4, extending between successive blades 10, 25, the wear plates being respectively fixed to the disc 7 and ring 9 and thus protecting one of the surfaces of each from wear.

Title: Starter Mechanism for use in a Machine for Handling Work Blanks
IPC: B21H9/02
Filed: 1967-10-06
Abstract: 1,170,829. Rolling threads; blanks transferring. HARTFORD SPECIAL MACHINERY CO. 6 Oct., 1967 [7 Dec., 1966], No. 45803/67. Headings B3B and B3M. A mechanism for feeding blanks from a feed shoot to a working station, which comprises, for example, a pair of thread-rolling dies 18, 20, includes a reciprocating starter blade 26 which is carried by parallel arms 94 and 96 pivoted at 52 and 92 and which is provided with a lostmotion connection with a driving crank 50 to prevent feeding movement of the blade in the event of jamming of a blank. Reciprocating movement of the blade is controlled by a pivoted crank 50 (Fig. 3, not shown), which is moved anticlockwise by an adjustable spring system 36 and which is moved clockwise by a pneumatic cylinder, or cam follower mechanism 35. Clockwise movement of the crank retracts the arm 94 and hence the blade 26 due to the abutment of faces 134 and 136 on the crank and arm 94. Upon anticlockwise movement of the crank the arm 94 is normally held in contact with the crank by the spring system 110. An extension 100 of arm 96 is biased by an adjustable spring system 110 to urge the blade 26 to the right. But in the event of the blade 26 jamming, the crank continues its movement, Fig. 5, while the arm 94 remains at least partly retracted. The relatively light biasing force of the spring system 110 ensures that the blade 26 is stopped readily, if jamming occurs, without causing undue damage to either the dies 18, 20 or the blanks. The feeding mechanism is suitable also for pointing, slotting, or head-trimming operations.

Abstract: 1410823 Photo-electric measurement of colour INSTITUT FUR GRAFISCHE TECHNIK FORSCHUNGSINSTITUT DER DEUTSCHEN DEMOKRATISCHEN REPUBLIK FUR DIE POLYGRAFISCHE INDUSTRIE 6 Oct 1972 46132/72 Heading G1A The colour of a moving printed web is measured by illuminating a small surface area with a plurality of light sources, of different narrow spectral ranges, which are pulsed in succession. In the arrangement shown, the plurality of light sources 2, which may be luminescent or laser semi-conductor diodes e.g. in an integrated circuit arrangement, are arranged at equal angles to the area 3 to be illuminated. The reflected light is detected by a photo-diode 4. The sources are energized under the control of unit 6. This is triggered at set times t 1 , t 2  etc by a synchronizing arrangement (not shown) via pulse shaper 5, so as to produce at each time ti, t2, a series of pulses 1 ... a of equal number to the number of sources, so as to energize these in sequence via cooling and de-coding circuits 7, 10 and amplifiers 11. The series at time t 1  is applied to an unprinted part of the web to provide reference signals and that at t2 to a coloured (printed) part. The reflected or transmitted pulses of the first series at time t 1  after detection at 12 are fed via logarithmic amplifier 12 through amplifiers 8, 9, which are both gated (under control of unit 6). The signals at the outputs of differential stores 13, are at this time ti zero, and the value held in the stores are reference measurements. The reflected or transmitted pulses resulting from the series starting at time t2 are only gated through amplifiers 8. In stores 13 a comparison is performed between the stored reference value and the incoming measurement signals and the outputs represent the reflection or transmission differences, Computer 14 may analyze the difference signals for use in controlling the printing operation. An analogous system for transmission measurements is envisaged..
