Title: Improvements in shears for trimming thick metal sheets or plates
IPC: B23D31/04
Filed: 1965-12-31
Abstract: 1,081,496. Shearing. SCHLOEMANN A.G. Dec. 31, 1965 [Jan. 22, 1965]; No. 55355/65. Heading B3W. In a reciprocating shear the upper blade beam 16 is driven by a main crank-shaft 2 and connecting rods 14 and 15 and in addition to its rectilinear movement has a rocking movement which is produced by a subsidiary crank-shaft 3 which is connected to a rearward extension of the blade beam by a rod 37. The crank-shafts 2 and 3 are geared together by toothed wheels 4, 5, 6 and 7, Fig. 2, and the subsidiary crankshaft 3 has its crank angularly displaced relative to the crank of the main crank-shaft so that the connecting -rod 37 leads the connecting rods 14 and 15 of the main crank-shaft. A pivot shaft 38 is fixed in the upper blade beam and pivotally carries at each end a slide block 39. These slide blocks are each guided between two wedge-shaped members 40 and 41 which are mounted on, and are displaceable vertically in the shear frame. The displacement of the members 40 and 41 is effected by rods 45 which are driven through worm-gear by a motor 42. Simultaneous vertical movement of the members 40 and 41 produces horizontal movement of the blade beam for adjusting the working clearance between the cutters. A cylinder (46), Fig. 3 (not shown), biases the blade beam towards the wedge 41. In a modification, Fig. 4 (not shown), there is an intermediate pinion (56) between the toothed wheels mounted on the crank-shafts so that the shafts rotate in the same direction and in this embodiment the guides for the upper blade beam comprise slide shoes (66, and 67) which are pivotally mounted in the front and rear respectively of the blade beam. The shoes (66) run on rails (68) which are acted on by springs and the shoes (67) engage tapered members (69) which are, arranged to slide on correspondingly tapered bearing members (70) attached to the shear frame. To adjust the working clearance between the cutters the tapered member (69) is raised or lowered by a vertical spindle (71) which has a threaded upper end which passes through nuts (72) and (73). In both embodiments the shear is one of a pair which are mounted face-to-face on a common bed and are used for trimming the edges of metal plates which are moved between the shears on a roller table. The shears are movable on the common bed by means of motor-driven screwed spindles 27 and 28 which pass through nuts 29 secured to the shear frame. The shears are each driven by a motor 8 and to ensure synchronous running the motors are connected together either electrically or by mechanical means comprising shafts 34 and 35 and gearing 31, 32, 33.

Abstract: 1413666 Photo-electric scanning arrangements BENDIX CORP 30 Nov 1972 [13 Dec 1971] 55364/72 Heading G1A [Also in Divisions G2 and H4]  In a system for scanning a light beam across an object and directing the reflected light to a detector, the light beams from the source to the object and from the object to the detector are reflected from different facets of a rotating mirror drum and an attenuator to provide substantially constant overall transmission for all angles of reflection is incorporated in the path between the object and the detector.  As shown, Fig.2, light from a source 2, which may be a laser, is reflected from one face 12' of a mirror drum 11 on to the object 22 which may be marked with coded information, so that as the drum rotates the beam scans along the object. Light scattered from the object is reflected by a second face 12" of the drum and a fixed mirror 36 to a detector 39. An attenuator comprising a plate with a suitably shaped elongate slot Fig.6 is arranged in the reflected light path to compensate for variations in detected intensity due to the changes in the projected area of the reflecting face 12 and in the variations in distance of the illuminated portion of the object from the drum during each scan. An interference filter 38 is placed in front of the detector, the variation in transmission with angle of incidence being used to compensate for differences in optical path length due to variation in position of successive objects relative to the drum.

Filed: 1972-12-20
Abstract: 1417850 Electric selective signalling H KAFAFIAN 20 Dec 1972 [24 Feb 1972] 58855/72 Heading G4H A communication system for the handicapped comprises a single-input transducer (e.g. a switch 8) connected to apparatus which provides a dual output representing a selected row and column of a matrix 32, e.g. for the selection of a character on a typewriter keyboard (Fig. 2, not shown). In the embodiment of Fig. 1 the first closing of switch 8 sets a flip-flop CB1 to activate a generator 11 which sends pulses via a gate G5 to a driver 19 for row stepping switches RSS(1)-RSS(3). When switches RSS(1) have stepped to the desired position (row), as indicated by lamps energized by RSS(3), switch 8 is released. This sets a flip-flop CB2 to close G5 and halt the row switches RSS; a gate G7 is opened to connect generator 11 with a driver 25 for column stepping switches CSS(1)-CSS(3). When CSS(1) has reached the desired position (column) as indicated by CSS(3), switch 8 is closed again to set a flip-flop CB3 and reset CB1 (disabling generator 11). CB3 starts a print pulse generator 31 which feeds a "print" flipflop 29 whose output passes to matrix row and column drivers 34, 36 and thence via switches RSS(1), CSS(1) to the appropriate row and column of matrix 32. The output therefrom may pass to a code converter 50, and can be used to operate equipment 60 other than typewriter 38. Means 39 allows single or repeated printing of a character by 38. Releasing switch 8 finally resets the apparatus. In another embodiment (Fig. 3, not shown) it is not necessary to hold switch 8 closed to keep the switches moving; 8 is closed a second time to stop RSS and start CSS, and a third time to stop CSS and generate the output signal.

[Also in Group XVIJ A franking machine (see Group XVI), e.g. for printing stamps on cards or letters, consists of two parts, an operating unit and an interchangeable franking unit, each such unit being adapted to print stamps of a particular value and containing counting means for registering the total number of operations of the unit and the prepaid credit remaining to the unit. The number of operations made by each franking unit is registered by a mechanism in the unit which comprises two sets of counting wheels 100, 101, Fig. 8, mounted on shafts 102, 103, and visible through a window 105. Wheels 100 register the credit remaining to a unit and wheels 101 the total number of operations. A gear wheel 106, driven from gear 58 on the driving shaft 55 of the franking unit, drives a pair of Geneva shafts 107, 108 operating the sets of counting wheels. Stop mechanism.-A locking device is provided for preventing further operation of the machine when credit is exhausted. This comprises a comb consisting of a number of teeth 109 mounted on a shaft 110 and urged by a spring towards the circumferences of the counting wheels 100. The teeth are staggered so that the end tooth bearing on the wheels of highest value maintains the other teeth out of contact with the corresponding wheels. When the highest value wheel comes to zero the corresponding tooth enters the recess 113 and locks the wheel, the next tooth then bearing on the next wheel and locking it when it comes to zero and so on until all the wheels are locked in the zero position indicating that credit is exhausted. The movement of the comb towards the wheels rotates a lever 112 mounted on a shaft 110 into engagement with a notched disc 60 and prevents further rotation of the shaft 55. Particular setting mechanism.-The credit wheel of highest value is fixed to shaft 102 which is rotated to reset the credit mechanism. The other credit wheels are loose on the shaft 102 and are not affected by this rotation. The shaft 102 is first displaced endwise by a knob 115, Fig. 2, to disengage the wheel from the driving Geneva shaft 107 and then rotated to the desired credit value. A notched disc on shaft 102 cooperates with a fixed pin so that the shaft 102 can only be returned to normal position when the credit wheel is reading an integral number. The knob 115 is obscured behind a cover 121 pivoted to the end wall 52 of the franking unit and sealed in position, e.g. by a Post Office seal, to prevent fraudulent alteration of the credit wheels. Movement of the cover to expose the knob 115 causes the rotation of a shaft 128, Fig. 8, an arm 129 on the other end of which contacts an arm 111 on the comb spindle 110 and swings the comb out of locking position.
