Abstract: 1469885 Pumps; hydraulic turbines KOBE INC 29 April 1974 18708/74 Headings F1C and FIT [Also in Division B2] In a single or multi-stage rotary chamber pump comprising a rotary casing 9, Fig. 1, defining a chamber containing stationary scoops 19, 20, the peripheral wall of chamber section 52 is provided with one or more orifices 71, Fig. 2, each large enough to permit foreign material present in the pumped liquid to pass therethrough to a point outside the casing but having a total cross-sectional area sufficiently small to avoid a substantial pressure drop in the chamber section 52. The foreign material may be sediment or relatively heavy liquid. The peripheral wall has a number of V-shaped zones 62 formed between shoulders 63 and communicating through passages 68 with an annular channel 67 in communication with the orifices 71 via further passages 20. The foreign material is discharged through the orifices into an outer housing 13 where it is collected for removal via pipe 77. The orifices 71 discharge tangentially so that some of the potentially-lost energy is returned by the jet effect of the discharging flow. The shape and dimensions of passages 68 are such that the passages collectively function as a strainer to prevent large foreign particles from entering the orifices. The passages 68 are angled as shown to impart a tangential velocity to the flow entering the channel 67 to prevent accumulations therein. The scoop 19 is provided internally with a vane 75.

Title: Electrical circuit means for use in acoustic emission detecting  and or recording apparatus
IPC: H03K19/173
Filed: 1971-08-04
Abstract: 1391175 Electric selective signalling CAMBRIDGE CONSULTANTS Ltd 2 Aug 1972 [4 Aug 1971] 18943/71 Heading G4H [Also in Division H4] Apparatus for detecting faults in stressed structures comprises transducers 2 arranged to detect acoustic emissions produced during testing, each transducer being connected to a respective counter 10 (or other detecting and/or recording medium), by a logic circuit 8 which ensures that only the signal from the first of the transducers to detect a stress wave is allowed to pass to the counter. Transducers 2 are accelerometers whose output waveforms take the form of sets of decaying sinusoids (Fig. 2, not shown); these pass to a device 6 which produces a square-wave pulse each time the input exceeds a threshold value. In the embodiment of Fig. 6, each device 6 and counter 10 is separated by an AND-gate 16 whose other input is a "1" from an inverter 22. The first pulse to arrive at any of the gates 16 passes through it to trigger a retriggerable monostable 26 and (via a gate 20), a monostable 18: the output from 18 acts through inverter 22 and OR-gates 24 to inhibit all the gates 16 except the first, which is kept open via its gate 24 and monostable 26 so that the remainder of the signal can be counted. The output from 26 is of shorter duration than that from 18 but it is longer than the interval between the pulses of the signal, so that these can continually re-trigger the monostable. Other embodiments are described (Figs. 3-5, not shown), wherein different arrangements of gates and monostables allow only the first pulse to pass to a counter, all the gates 16 being subsequently blocked.

Title: An improved start-stop mechanism for rotatable typewheels particularly suitable for printing telegraphs
IPC: H04L13/04
Filed: 1931-07-02
Abstract: 381,218. Type-printing telegraphy. CREED & CO., Ltd. and GRIFFITH, R. G., Telegraph House, Croydon, Surrey. July 2, 1931, No. 19079. [Class 40 (iii).] A friction clutch for driving a type-wheel or other rotary type-head is provided with means for absorbing shock and reducing torque when the type-head is arrested to effect printing. A driven member 4, Fig. 1, integral with the type-head is connected to a cup-shaped driving member 1 through a flat spring 5 which is connected to the driven member at 6, comprises 1¢ turns, and is in frictional engagement with the continuously rotating cup 1. The driven member 4 draws after it, by means of a second spring 8, a stop member 13 which, when the type-head is to be arrested in a required position, is engaged by one 3A of a set of selectors 3, the chosen selector 3A being moved for this purpose into the path of a tooth on the stop member 13. When the stop member 13 has been arrested in this manner, the driven member 4 runs on until its part 12 is forced by a cam 13A in an axial direction towards the selectors 3, so that it latches itself to a definite one of these selectors by means of a hook (not shown) and remains in position till the stop member 13 has been released by the withdrawal of selector 3A. The spring, 8 saves the member 4 and type-head shaft from shock, and moreover it is pulled away from spring 5 during the arrest process, so that the driving torque is diminished. Spring 5 is then free to wind up slightly, so as to diminish the frictional drive still further. In a modification, Fig. 6 (exploded perspective), the clutch is of the disc type. The driving disc 1 is pressed by springs 17 against a driven member 4 which, by means of a spring 8 attached to pin 23, draws after it the stop member 13, the relative movement of driven member and stop member being limited by stops 26. The stop member 13 has a tooth for engagement with the selectors 3, and when it is arrested the driven member 4 runs on, stressing the spring 8, until its stop 26 abuts against the stop member 13. A spring 14 carrying a latch 12 is mounted on the member 4 and is, during rotation, held out of engagement with the selectors 3 by a cam roller 27 engaging a cam plate 28. When arrest takes place, however, the plate 28 runs off the roller and latch 12 then engages a selector 3 so as to lock the member 4 and typehead in position. The type-head may comprise a type-wheel or a rotatable type-barcarrier of the kind described in Specification 311,684 [Class 100 (iv), Typewriters &c.]

[Also in Group XXIII] The welded joints of profiled rails are trimmed by a grinding-wheel or milling-cutter to a shape determined by the profile of the rail which is used as a template. The milling-cutter 44, Fig. 1, is carried in a box-type guard 53 on the end of an arm 45 pivotally connected by links 46, 47, to a ring 35, Fig. 3. The ring is rotatable, through an angle determined by a projection 41 and adjustable stops 42, on rollers 36 in a frame 30, which is mounted on wheels 31 on rails 32 and provided with a brake 33 for locking the machine in a desired position. A chain 37 is secured by its ends, one of which is adjustable by a screw to tension the chain, to the ring 35, and engages a sprocket 38 driven by a hand wheel 40 to rotate the ring at the same time as the tool 44, which is driven by a belt or chain 60, Fig. 1, and flexible shaft 61 from a motor 62, is reciprocated across the joint by a crank 49 and rod 48 driven by a chain 51 and electric motor 52. The arm 45 is urged by a spring or other means so that adjustable guides 54 on the guard 53 contact the rails on each side of the joint, and the tool trims the joint to the same profile as the rails. The arm 45 can be rocked on the link 46 to lift the tool and guides from the rails, by a flexible wire mechanism 58 actuating a member 56 and lever 57 associated with the link 47, which has an open-ended slot 55 to receive a pin on the arm. The excess weld-metal on the under surface of the rail can be removed by a tool 63, which is driven and mounted similarly to the tool 44, on a carriage 73. The tool can be traversed across the flat under surface of the rail, as it is reciprocated across the joint, by a lead-screw 74 rotated by a chain-drive 75 and hand wheel 78. The screw 74 and sprocket 38, which rotates the ring 35, may be driven through hand-operated clutches from an electric motor, so that either or both tools may be operated at one time. The upper and lower units may be separated to provide individual machines.
