Title: Cleaning apparatus
IPC: B01D61/10
Filed: 1974-04-24
Abstract: 1463421 Pipe cleaning apparatus DAICEL Ltd 24 April 1974 [25 April 1973] 17862/74 Heading F2N [Also in Divisions B1-B2] Tubular piping (12) of a fluid-flow system is cleaned internally by passing through it resilient compressible cleaning object or objects 1 propelled by fluid, the direction of which is reversed as necessary by a valve means (14), one or more cartridges 8 being connected to the piping for retaining the cleaning objects after their transit. A cartridge is attached to the piping at 9 and to the valve means at 2 and comprises a case 4 open at one end to receive the cleaning objects from the piping, closed at the other by a porous barrier 7, a passage 6 able to act as a fluid by-pass and a valve 3 in a tube 20 to control the fluid flow through the cartridge. The valve 3 is axially movable over a limited distance within the tube, movement being in response to fluid pressure on one of its end faces 10 and such that fluid flowing into the cartridge via opening 2 closes a hole 5 to the by-pass causing the fluid to pass through the case 4, ejecting any cleaning objects it contains, and fluid entering via 9 opens the hole 5 to enable the by-pass to be used, when for instance cleaning objects are present in the case 4. The piping may particularly be a tubular semi-permeable membrane used to purify water by reverse osmosis, the purified water being collected by a receiver (17) in which case the water may propel the cleaning objects or a cleaning fluid may be used. The cleaning objects are preferably sponge balls. Alternative forms of the valve 3 and barrier 7 are illustrated in Figs. 4 and 5 (not shown). Automatic switching of the valve means (14) by a timer to reverse the fluid flow allows automatic cleaning of the system.

Abstract: 562,483. Sewing machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Dec. 29, 1942, No. 18448. [Class 112] The underside of a rotary hook 15 has a flange 18, which may have conical sides, depending into an oil cavity 33 in the upper end of the hook-supporting saddle 28. An oil duct 60 opening from the cavity communicates with the spool-case raceway 161. The floor of the cavity 33 is provided by a hardened steel plug 64. Four balls 69 are placed between the hook and the plug 64 and are kept separate by a suitable-cage free to rotate. Oil passing into the cavity 33 from duct 67 is conveyed by the balls to the depending flange 18 and, so, to the duct 60. In a modification, the space within the flange 18 is filled by a felt pad which conveys the oil to the inner wall of the flange 18. In this construction, the plug 64 is not needed and its place is taken by an integral portion of the saddle 28.

Abstract: 1,272,175. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 17 April, 1970 [17 April, 1969], No. 18562/70. Heading H4P. In a data transmission system wherein each binary digit is represented by a main signal pulse and a predetermined number of preceding and following echo pulses at determined intervals, each main pulse is combined with at least one echo pulse associated with it to enhance the value of that pulse and hence improve the signal to noise ratio. The pulse sequence representing the data elements may be transmitted in succession to form a complex signal, with means for analysing it at appropriate instants, and means for multiplying the signals associated with some of the analysed signals by appropriate coefficients, hence a sum of the analysed signals may be produced, some of which are enhanced which are substantially unaffected by the echoes of other data elements. The echo pulses of other data elements which coincide with the echo pulses of the elements being operated on may be eliminated by the addition of further signals. Arrangements are described in the Specification (e.g. Fig. 2b, not shown) providing a series of delay circuits feeding into a summing unit so that pulses may be delayed by the appropriate time and added to following pulses.

Abstract: 498,304. Modulating - apparatus. FERNSEH AKT.-GES. July 5, 1937, No. 18599. Convention date, July 10, 1936. [Classes 39 (i) and 40 (v)] In a modulating device comprising an electron multiplier, the electrons in at least one stage of the multiplier pass through a magnetic field, the strength of which is varied at the carrier frequency. Secondary emitting electrodes 1, 2, 3, preferably earthed through capacities, are disposed opposite accelerating electrodes 2<1>, 3<1>, 4<1>, and a magnetic field produced by suitable means (not shown), causes the electrons liberated from 1 by the light signals focused onto it by the lens 11, to impinge on electrode 2 and produce secondary emission ; the process being repeated at each stage. The intensity of the magnetic field acting on electron stream 12 is varied at carrier frequency and results in a similar variation in the number of electrons impinging to the right of edge 8 on electrode 2. Those electrons which do not fall on electrode 2, pass through the slit 9 into the Faraday cage 10. The magnetic field may consist of alternations superimposed on a direct field of constant strength, or may change its direction. The variations of the field may contain harmonics of the carrier frequency.

The addition of an anti-knock liquid, which may comprise additional fuel to produce an over-rich mixture, a fuel of higher anti-knock value than the 'normal fuel, or an anti-knock substance such as aniline, to the combustible mixture is controlled by a valve actuated in accordance with the sum of the effects of intake manifold suction and the suction at the throat of the carburetter Venturi. In Fig. 5 the normal fuel is fed through a nozzle 137 and the anti-knock liquid flows to a nozzle 122 past a valve 134 actuated by diaphragms 117, 118 subjected respectively to the intake manifold and Venturi suctions, the total force on the two diaphragms being arranged to allow the valve toi open only during detonating periods. In a modification the pressure responsive device actuates two valves simultaneously so that the flow of the normal fuel is reduced when the flow of the high anti-knock value fuel is started, the two fuels flowing to a single nozzle. In Fig. 4, a valve 13 controlling an orifice 9 in parallel with the usual metering jet 4 is actuated by the pressure-responsive device 10 to increase. the supply of normal fuel to the nozzle 7 to produce an over-rich mix-, ture during detonating periods.

Abstract: 257,246. British Thomson-Houston Co., Ltd., (Assignees of Traver, O. C.). Aug. 20, 1925, [Convention date]. Cut-out arrangements; induction relays. - In order to cut-out a faulty section of a system selectively in accordance with the reactance or resistance of the section without interrupting continuity of service on the remainder of the circuit, each section is protected by a relay arrangement comprising a pair of co-operating contacts 7, 6 operable respectively by a current actuated inverse time-limit device 1 and by a device 2 operating in accordance with an ohmic characteristic of the circuit. In the arrangement shown, the device 2 operating the contact 7 is of the ohmmeter type and comprises two fixed coils 18, 19 energized by the current and potential of the section respectively, and one movable coil 20 to operate the contact 7 energized by the potential or by the current of the circuit. The ohmmeter device positions the contact 7. without time-lag, in accordance with the resistance or reactance of the section. On overload, the induction disc motor 8 (which is of the overload time-limit type with a serrated edge to give torque compensation, as described in Specification 210,092) moves at a speed depending on the overload, and, if the resistance of the section is very low, the contact 6 almost immediatelv reaches its companion contact 7 and the circuitbreaker 4 is tripped. If the resistance or reactance is higher, more time is consumed and thus the desired selectivity is obtained. The ohmmeter device and the time-element overload device may be of the induction disc type with opposing current and potential coils.
