Title: Improvements in or relating to the manufacture of saw-segments for circular saws
IPC: B23D63/00
Filed: 1951-01-29
Abstract: 695,732. Making saws. SMAL, G. Jan. 29, 1951 [Feb. 3, 1950], No. 2222/51. Classes 83 (ii) and 83 (iii). [Also in Group XXIII] Milling; drilling.-In a method of making a circular saw in which toothed segments are attached to a disc, trapezoidal plates from which the segments are machined are provided with two lateral grooves which are used to locate the plate during some or all of the machining stages. A plate 1, Fig. 14, for a saw segment is given two semicircular locating grooves 2, 3 in its ends and two V-grooves 49, 50 in its outer corners. The grooves 2, 3 subsequently form rivet holes when the finished segments are assembled on the saw disc. In machining the end faces, the plate is held by a clamp 10, Fig. 6, on a fixed base-plate 8 and located between a fixed pin 6 and a pin 7 which is adjustable in position on the plate for accommodating different lengths and segmental angles of plates. For grinding the inner and outer curved edges and for grinding a groove or tongue on the inner curved edge, the plate is located by pins 13, 14, Fig. 8, and clamped by a cam 25 on a plate 15 which is pivoted at 16 and guided by arms 19, 20 on a slide 21 movable under a grinding wheel 28. A cam 22 attached to the plate 15 and riding over a fixed roller 23 gives the work the required vertical movements, a spring 17 yieldingly engaging the cam 22 against the roller. For cutting the outer curve of the segment the cam 22 is changed to one of concave shape. For machining the side faces, the segment is located by pins 48 on a plate 47, Fig. 30. For grinding the teeth, the segments are located by pins 34, 35, Fig. 24, on a plate 36 in a grinding machine, the grinding tool 37 of which is moved by mechanism (not shown). For drilling the rivet holes, the segment is located by pins 39, 40, Fig. 26, on a base-plate 43 to which a jig 41 is pivoted at 42. The corner grooves 49, 50 which are removed when the outer curve of the segment is cut, are used only in grinding inclined side faces 45, 46, Fig. 19, by a tool 59, the segment being located centrally between a tongue 56 having projecting portions 57, 58, Fig. 20, engaging each groove and a tongue 55 engaging the recess 30 on the inner curve of the segment. The tongue 55 is attached on the end of slide 60 on a machine bed and is operated to engage the segment by a cam 61.

Title: Scrap preparation
IPC: F25D29/00
Filed: 1973-01-16
Abstract: 1451342 Scrap preparation BRITISH STEEL CORP 16 Jan 1974 [16 Jan 1973] 2263/73 Addition to 1381726 Heading C7D In a process for preparing cooled metal scrap for fragmentation, the primary loop 10 of a heat exchanger 13 contains a liquid cooling agent i.e. methane which is compressed and circulated through a liquifaction plant 12. The secondary circuit 11 of the exchanger 13 contains cooled gaseous nitrogen or air, which is continuously fed to chamber 14 to cool the scrap therein, and is driven back to heat exchanger 13 by blower 16 via valves 15, 17, 18. The cooled scrap is withdrawn at intervals and fed to fragmentation unit 25. An auxiliary circuit 19 connected by valves to secondary circuit 11 and controlled by a proportional controller 26 actuated by pressure differences between a pre-set (normally atmospheric) level and a pressure transducer 27 in circuit 11 allows any loss in gas pressure due to leakage from chamber 14 to be made up from an ancillary dry nitrogen supply 21. A modification employs mass flow transducer instead of a pressure transducer, immediately before and after chamber 14 in circuit 11 to control the amount of nitrogen admitted from supply 21. A further modfication comprises 60 and cools 61 the auxiliary gas before it enters circuit 11  through control valve 64 again actuated by controller 26 and transducer 27. In yet a further modification, the cooled scrap 44 from chamber 14 is supplied to a secondary cooling system 42 and further cooled with liquid nitrogen through sprays 43 prior to passing to the fragmentation unit 25. The vapourized liquid nitrogen collected below the scrap is supplied to a high pressure blower and receiver 48 and injected into circuit 11 through a series of valves to act as the auxiliary gas supply. The scrap may be pre-cooled prior to entering chamber 14 by the cooling gas bled from valve 41 in the cooling circuit 11. (For Figures see next page)

Title: Apparatus operating at predetermined times
IPC: G04B23/08
Filed: 1946-01-23
Abstract: 607,043. Time alarm signals. NILSON, C. E. J. Jan. 23, 1946, No. 2296. Convention date, Jan. 26, 1945. [Class 118 (ii)] [Also in Group XXXVII] Apparatus operating a movable member at predetermined times comprises a rotatable drum having recesses in which pins may be selectably positioned so that at the required times a pin co-operates with a protuberance on a rotatable roller mounted on the said movable member in order to displace bodily the roller and movable member. A drum 6 composed of four discs 7 and a single-toothed disc 27 is driven by gearing 13, 14 at a constant speed and rotates once in six hours. At each revolution the disc 27 steps on a roller 18 comprising four toothed discs 19 by the width of one tooth. To provide the same programme of operation on each of seven days, each disc 19 has seven equally-spaced teeth 23 and is offset from the adjacent discs by one tooth. The discs 7 have sixty slots 11 around each periphery, representing intervals of six minutes, in which pins 12 may be inserted to mark desired times. During the first revolution of the drum 6 any pins in the first disc 7 will press a corresponding arm 24 against a tooth 23 on the first disc 19 and thus force the roller 18 away and so rotate the lever 15 clockwise about its pivot 16. During the next six hours any pins in the second slotted disc 7 will co-operate with a tooth of the second disc 19 of the roller 18, via the medium of a second arm 24, and so on. Thus, any six-minute period in a day may be marked by the movement of the lever 15 which may give a signal, or electrically or mechanically control other apparatus and the day's " programme " is repeated seven times before the cycle recommences. To provide a different " programme " on, say, the seventh day, one set of four discs 7 co-operates with teeth on a set of four discs 19 during the first twenty-four revolutions of the drum 6 and two second sets of four discs 7 and 19 co-operate during the next four revolutions. For this purpose the first four discs 19 are cut with six teeth only, spaced as shown, and the remaining four discs cut with one tooth each, fitting in the gap between the first and last teeth of the other discs 19. The drum 6 and roller 18 may be solid cylinders with holes or protuberances respectively.

Title: Improvements in and relating to guards for machine tools
IPC: F16P3/04
Filed: 1946-01-26
Abstract: 607,140. Machinery guards. COLE, Ltd., E. K., and STEWARD, A. Jan. 26, 1946, No. 2618. [Classes 80 (ii) and 80 (iv)] Guarding means for bending machines or the like comprises a bracket 12 and guard 13, the latter being slidable over the former, the parts 12, 13 being locked in guarding position when the machine is started, and the guard 13 being raised during the latter part of the stroke of the tool F. Before starting the machine, a control lever 1, pivoted on an arm 2 of a transverse shaft 4, is pulled down to rotate the shaft 4 and release a pawl 5 from engagement with a slot in a disc 6 on the driving shaft C. At the same time a pawl 27, Fig. 3, connected by links 7, 8 to the. shaft 4 is moved out of the path of an arm 41 to permit actuation of the machine brake and clutch mechanism. Also arms 2, 2a on the shaft 4 carrying rods 10 connected to the bracket 12, move the latter downwardly. During this movement the bracket 12 is locked to the guard 13 by spring-actuated pawls 19, which are pivoted on the bracket 12 and engage stops 21 on the guard 13. As the guard is now in full guarding position, the machine is ready for actuation by the movement of the clutch control lever 33, Fig. 2. Movement of lever 33 actuates the arm 41 via a two-part link 31 and crank 40, and the beam E and tool F then make a working stroke. As the beam E descends brackets 20 thereon engage nuts 35 on rods 18, and collars 23 on the latter disengages the pawls and stops 19, 21, and on further downward movement nuts 38 on the rods 18 engage and pivot the levers 15, which by rods 16 partly raise the guard 13 to permit the work to be bent. As the beam E moves upwardly, the guard 13 drops back again to its full guarding position. Operating clutches.-To permit of only a single working stroke, one part of the link 31 carries a pivoted hook 30 which engages a pin 43 on the other link part. The hook 30 is connected to one end of a sliding rod 29, the other end of which lies in the path of an abutment 28 on the fly-wheel J of the machine. Thus, when a working cycle is nearly completed, the abutment 28 strikes and depresses the rod 29 to uncouple the parts of the link 31, whereupon counterweights (not shown) cause the crank 40 and arm 41 to return into the position to engage the brake and release the clutch. The bracket and guard 12, 13 return to the guarding position and the safety pawl 5 re-engages the slot in the disc 6. The bracket 12 may be in two parts, one at each end of the member, and the guard 13 may carry an adjustable extension 14.

Filed: 1933-01-30
Abstract: 412,663. Controller handles. WEST & CO., Ltd., A., and TAYLOR, W., Lewes Road, Brighton. Jan. 30, 1933, No. 2878. [Class 38 (iii).] A dead-man's handle comprises an operating handle which must be moved transversely with respect to its normal movement against a spring, in order that it may be effectively employed in its normal movement to operate the control apparatus, and means are provided whereby the reaction exerted on the handle by the spring in the operative position, although greater than zero, is much less than that exerted when the handle is being moved to said operative position. A push rod 3 passing through the handle bars 1 is spring biassed upwards to open contacts and render the controller ineffective. When the pivoted handle 2 is depressed, an adjustable pin 8 acts on a pivoted arm 7 and depresses the rod 3 to close the contacts. The end of the arm 7 travels along the edge of a latch 10, and, in its fully depressed position, engages a shoulder 10<a> of the latch 10. The handle 2 in the depressed position also causes a spring plunger 11 to act on the latch 10, and, with slight force, maintain it in engagement with the arm 7. Small upward movements of the handle 2 are then ineffective, but release of the handle frees the latch 10 which is moved clear by upward movement of the arm 7 under the influence of the spring bias acting on the rod 3.
