Patent GB-1505186-A (GB)
Title: Detector system
IPC: G01V3/11
Filed: 1975-05-02
Abstract: 1505186 Detecting metal GOODYEAR TIRE & RUBBER CO 2 May 1975 [28 May 1974] 18412/75 Heading G1N [Also in Division H3]  In an arrangment for detecting foreign metal in a non-metallic material in which the material is moved past a detector effects of noise and random signals e.g. due to moving machinery, are obviated by selecting only those signals from the detector which have a duration related to the speed of movement of the material past the detector head and the geometry of the latter. In the arrangement of Figs. 2a, 2b a detector 10 of the type in which an electromagnetic field is disturbed by metal is positioned adjacent a conveyer belt moving at a constant speed and carrying the material. The output pulse e 1  from the detector is integrated at A-1 which is also provided with a negative feedback lowpass filter R2, R3, C3 to prevent slowly changing signals from being integrated and the inverted integrated signal e 2 , after rectification and clipping e3 by diodes D1, D2, D3 is differentiated es by C4 and R6. The differentiated signal is on the one hand inverted es and fed to one input of gate G-3 and on the other hand is applied to gate G-1 and one shot multi-vibrator DY-1 to produce pulse e 6  the trailing edge of which triggers a further gate G-2 and one shot multi-vibrator DY-2 to produce pulse e 7 . This latter pulse after inversion at 20, is applied as a window gate pulse e 8  to gate G-3. Thus if the positive pulse of waveform e 5  arrives at the gate G-3 during the period of pulse e 7  it is allowed through and an indicating device is triggered to produce a signal indicative of metal in the material on the belt. Longer or shorter pulses established by e 3  do not pass through G3. In an alternative embodiment Fig. 3a the detector output e 1  is operated on by a series of linear integrators 22, 24, 26 each being provided with a low pass negative feedback filter R 2 , R 3 , C 3 . Those signals from the detector which have a duration determined by the transit time of a piece of metal through the detector pass through the integrators and are compared with a reference signal in amplifier A3 whereas signals of greater or less duration have their amplitudes reduced by the integrators and do not reach the threshold of amplifier A3. The signals due to metal which exceed the threshold cause the indicator connected to line 28 to be activated. Capacitor C5 prevents transient comparison voltage variations from causing spurious outputs.

Title: Apparatus for handling signatures
IPC: B65H31/04
Filed: 1974-04-26
Abstract: 1471069 Sheet ordering HARRIS CORP 26 April 1974 [7 May 1973] 18462/74 Heading B8R Signatures delivered from a printing press in a loosely shingled array are forwarded by three laterally spaced conveyer tapes at station 11 to a dense shingling station 12 where they pile up against the inclined surface 43 of a member 42 mounted on movable belts 13, 14 which retract the member as the shingled stack grows. When a stack is completed, as sensed by a switch 50, and when a gap in the forwarded array is sensed by a photo-electric cell 140, a stacking tray 15, of the type disclosed in Specification 1,424,838, between the belts 13, 14 is raised to remove the stack to a remote location. The gap may be caused by a clamping device or a diverter which guides succeeding signatures to a second dense shingling station. Fingers 40, 41, cams (49), Fig. 4 (not shown), retractable guides 90, 91 and a presser roller 65 and/or tapes facilitate stacking. The roller 65 and the central conveyer tape at station 11 are pneumatically retracted when the tray 15 is raised. A sensor 111 comprises three spaced switches which detect the rate of build up of the stack and initiate and control the speed of retraction of the member 42. A counter may be used to determine the number of signatures to be stacked on each tray.

Title: Improvements relating to conveyor belt apparatus
IPC: B65G39/10
Filed: 1944-09-27
Abstract: 590,008. Endless-belt conveyers. MILIK, R. Sept. 27,1944, No. 18464. [Class 78(i)] A conveyer belt 1 is supported by one or a set of rollers 2, 3 on a transversely extending arm or cradle 4 which is pivoted or hinged at one end to a side support or pedestal 10 near one edge of the belt 1 in such manner that the arm 4 and roller or rollers 2, 3 can be swung out of the transverse supporting position, whether or not the belt is in motion, about an axis 12 slightly tilted from the vertical in a direction such that the outward movement is also a slightly downward movement. The hinge carrying.side support consists of a collar 8 hinged at 9 and adjustably clamped by a screw 11 to a suitable pedestal such as a pit prop 10. Lugs 7 on the collar 8 are so positioned that the hinge pin 12 of the arm 4 is inclined slightly to both the longitudinal and transverse axes of the belt. The axis of the hinge pin 12 makes approximately a right angle with the axis of the outer roller 2 to ensure that it may clear the belt when it is strained by load into a V-shaped section. The support for the outer end of the arm 4 is a pedestal 13 the height of which is adjustable by a member 15 which carries a socket at its top to receive a locating pin in the end of the arm 4. The lower return run 16 of the conveyer belt may be supported by rollers on a similar hinged arm but is preferably supported by rollers on plain bearings secured to a fixed bracket 19 on the collar 8 and a vertically adjustable block 20 on the pedestal 13.

Title: Improvements relating to the manufacture of bricks
IPC: B28B15/00
Filed: 1945-07-20
Abstract: 596,131. Making bricks. WHITELEGGE, J. G. July 20, 1945, No. 18604. [Class 87(i)] [Also in Groups XII and XXX] In the manufacture of bricks, the bricks, stacked on carriers, are dried and fired in a tunnel kiln, the carriers passing one by one from the kiln to an unloading device and from thence to a loading device and back into the kiln, the movements being all timed automatically to give continuous operation. As shown, a number of kilns 5 are served by endless-feed and discharge conveyers 6, 7, the former receiving trucks 12 in succession from a ram 22 and positioning each truck before a predetermined kiln 5 into which it is pushed by a ram 9. This displaces a truck with fired bricks from the kiln on to the discharge conveyer 7 which conveys it to the pusher 50 and an unloading device 51. The latter may be a tippler or may comprise pivoted arms or jaws which close on a number of bricks, swing and drop them on conveyers 52, 53, which feed a hopper 54 under which a wagon may be driven. The return conveyer 8 is filled with trucks, the end truck 12 being opposite to the loading device 13. The raw materials first pass through a granulator and stone separator 14 and from thence by conveyer belts 15, 17, 16 to further granulators 18 and a pug mill 19 and finally to a forming machine, such as a wire-cutting table or a press. The green bricks are carried by conveyer 21 to the loading device (see Group XXX) which stacks them on a truck 12, the charged truck being then moved by a conveyer 33 to a position before the rain 22. If a length sufficient for a number, say ten, of bricks, is produced by severing from an extruder the length is pushed through cutting wires by a pusher 24 on to the conveyer 21, the pusher being actuated by a pivoted arm 25 driven by a crank pin 26 on a continuously rotated shaft 27 which drives the conveyer 21 intermittently through an interrupted gear 28, gear 29, chains 30, 32.

Title: Disazodyestuffs containing copper
IPC: C09B35/20
Filed: 1952-07-25
Abstract: Cupriferous disazo dyestuffs are manufactured by coupling 1 mol. of a diazotized 4 : 41-diamino-3 : 31-dialkoxydiphenyl first with 1 mol. of 1 : 8-dihydroxynaphthalene - 3 : 6 - disulphonic acid and then with 1 mol. of a nitrogen-free hydroxynaphthalenemonosulphonic acid (which may be further substituted by hydroxy, halogen or alkoxy), and treating the resulting disazo dyestuff with an agent yielding copper. Advantageously the first coupling is performed in a neutral to weakly alkaline medium, and the second in a medium rendered more strongly alkaline, e.g. by the addition of excess of sodium carbonate, an alkali metal hydroxide, ammonia, calcium hydroxide or barium hydroxide.  The coppering is preferably effected in the presence of an alkaline agent (e.g. ammonia, an aliphatic or cycloaliphatic amine, or pyridine) by means of a cupric salt, if desired in admixture with a cuprous salt.  In examples, the tetrazo component is dianisidine and the second coupling component is: (1) 1-hydroxynaphthalene-5-, -4-, or -3-sulphonic acid; (2) 2-hydroxynaphthalene-4-, -6-, or -7-sulphonic acid; (3) 2 : 8-dihydroxynaphthalene - 6 - sulphonic acid or 1 : 8 - dihydroxynaphthalene - 4 - sulphonic acid.
