Abstract: 1,269,815. Recording-apparatus. TROLEX AGENCIES Ltd. Sept.30, 1970 [Oct. 7, 1969], No. 49119/69. Heading G1J. A device for recording the occurrence of signals on a number of outputs comprises means for scanning the outputs, a digital timing device 4 and a printer 5, 6 which when operated records the reading of the counter and the timing device, the printer being actuated when the scanner scans an output at which a signal is present, the printer thereby recording the identity of the output and the time at which the signal appeared. In the form of Fig. 1 a clock pulse generator 9 energises a coil 1a to step round a selector switch 1 scanning terminals 2. Switches 1, 2, 3 etc. close if some undesirable condition arises (e.g. in a process plant or machine) applying a signal to the corresponding terminal 2. As the wiper 1 revolves a print wheel rotates with it being numbered corresponding to the switches. The timing device 4 presents a digital representation of the time and/or date. When wiper 1 reaches a marked terminal 2 a signal passes to unit 8 to energise printing coil 7 and operate print hammer so that the number and time are recorded on a chart 6. In another form the alarm switches are scanned at high speed by a counter advanced by a high speed clock when a closed switch is scanned a corresponding memory is set, and a signal passes to stop the high speed clock and hold the counter in this position, which the corresponding output marked. The counter outputs are connected to the terminals 2 of the selector switch 1 which is set in motion at the same time as the high speed clock is stopped. The identity of the marked input and the time of occurrence of the signal are then printed as before.

Abstract: 1322954 Pattern making; milling J T PARSONS 20 Oct 1970 [20 Oct 1969] 49765/70 Headings B3F and B3K A method of manufacturing combustible patterns from foamed plastics materials, e.g. polystyrene, comprises machining a billet of the pattern material using rotary cutters. A programme-controlled milling machine is employed which is modified to cut the pattern at least 100 times faster than if the pattern were being made from steel. A plastics billet is chucked in the milling machine and the approximate shape (Fig. 1) of the finished pattern is cut with a rotating blade cutter 34 having a depth of cut f. A single circuit of the billet straightens edge 11 and provide recesses 14 in the sides 12 of the billet. Large radius fillets 39, of radius equal to the depth of cut f are formed by abruptly moving the cutter perpendicularly to the billet wall 12. Holes 37 are cut by plunging the cutter into the polystyrene billet and following an endless path with the cutter. The pattern is finished using a further cutter 40 having a smaller depth of cut g which is used to finish holes 37 leaving fillets of radius g at their corners and provide a ledge 15 with small radius fillets 19. To provide the fillets 19 the lower corner 45 of the cutter is rounded. A further step 17 is made by lowering the cutter 40 and effecting a further circuit of the hole 37.

Abstract: 1404615 Workpiece feeding apparatus SYBRON CORP 31 Oct 1972 [10 Jan 1972] 50127/72 Heading B8T In an apparatus for feeding workpieces to processing equipment, a feed mechanism with a plurality of pockets to receive work at one point and deliver it to another, has a detecting sensor permanently asssociated with each pocket which activates a control mechanism to initiate operations on the workpiece. Containers 10 picked up from conveyer 12 by the pockets 27 of a rotary star wheel 13 are fed to gripping chucks 20, which are located on the periphery of the filling wheel 14 below the filling assemblies 15. A fluidic sensor 40, an inverter 42, control valve 43, cylinder 35 and cam 30 are mounted at each pocket 27 on the star wheel. The cams 30 are normally in the path of the cam followers 32 attached to the valves 18 of each of the filling assemblies 15. As each container is transferred from wheel 13 to filling wheel 14, cam follower 32 on the filling assembly 15 moves past the corresponding cam 30 on the star wheel and opens valve 18 to fill the can. However, if a pocket 27 is empty, the fluidic sensor 40 stops sending a signal to its associated inverter 42, which then sends a signal to its control valve 43 which opens a high pressure air supply to the corresponding cylinder 35, thereby pivoting cam 30 at the empty pocket out of the path of cam follower 32 so that the filling valve 18 will not open at the empty filling station. The invention may be applied to filling, washing, capping and labelling machines.

Abstract: 1,097,693. Facsimile telegraphy. MUIRHEAD & CO. Ltd. Nov. 26, 1965 [Dec. 10, 1964], No. 50393/64. Heading H4F. A feeding arrangement for a facsimile telegraph drum comprises means for releasing and discharging paper already on the drum and for drawing off paper from a supply roll, guillotining it to a desired length and wrapping and securing such length around the drum. The paper is secured by means of clips 5, 6, Figs. 1 to 5 (also Figs. 13 to 20, not shown) running the full length of the drum and normally retained in a paper gripping position by means of springs (17, 17<SP>1</SP>), the paper being released on lifting the clips by means of arms (16, 16<SP>1</SP>) operated by further arms (18, 18<SP>1</SP>) from a cam system (Figs. 7 and 8) which is driven by a low-speed motor clutched in automatically at the end of a normal scanning sequence when the drum has been brought to rest. The low-speed motor then rotates the drum to a reference position (Fig. 13) and brings rollers (A and B, Figs. 8 and 13 to 20) to bear on the paper surface. The discharge operation then comprises the steps of lifting clip (5, Fig. 14) to allow the leading edge of the paper to be raised by means of fingers (12) and on continued rotation, to be received by tines (64) which guide it to developing and fixing baths (66, 67). Fresh paper (65) is then introduced in rollers (28, 28a, Fig. 16), clip 5 being lowered to clamp it (Fig. 17) and clip 6 lifted to free the trailing edge of the discharging paper (Fig. 18). On further rotation a guillotine (53, 53a, Fig. 20) is operated and the trailing edge of the new sheet is then clamped by the lowering of clip 6. In addition to controlling the operation of clip 5 and 6, the cam system (Figs. 7 and 8) also controls the operation of the paper feed rollers (28, 28a), the guillotine and the raising of rollers A and B when necessary to grip the edge of the new paper and to clear the clips 5 and 6. During the initial stage in the supply of new paper via the feed rollers (28, 28a) and during the operation of the guillotine the rotation of the drum is arrested due to small gaps in the teeth of gear-wheel (61, Fig. 12) and is held steady in each arrested position by a member (63, Figs. 7 and 12) rotating with the drum and provided with projections (63a) arranged to engage projections (61a, 61b) on gear-wheel (61).
