Title: Measuring apparatus
IPC: G01B11/00
Filed: 1975-08-22
Abstract: 1516536 Measuring displacement photoelectrically FERRANTI Ltd 23 Aug 1.976 [22 Aug 1975] 34859/75 Heading G1A Apparatus for detecting relative motion between members 2, 4 includes: a scale grating 1 attached to one member and extending in the direction of relative motion 5; an index grating 3 carried by the other member; means 6 for illuminating directly the scale grating 1, the arrangement being such that radiation passing from the scale grating 1 to the index grating 3 is at least partly diffuse; and means 8-11 for detecting the resulting spatially periodic distribution of radiation produced by the index grating. The index grating 3 need not be very close to the scale grating 1, nor need it be strictly parallel thereto. Equations are given for determining the relative dispositions of gratings 1 and 3 and the detector means 8-11, and the resulting spatial distribution of the detectable fringes. As shown, diffuse light is provided by a lamp 6 having a filament extending in the direction of relative motion and a lens 7 for concentrating the light so that the whole of the index grating 3 is illuminated by reflected light from many directions, whereby contamination of part of the scale grating 1 does not substantially impair the fringe pattern. Alternatively the scale 1 may itself be diffusely reflective or transmissive. A third grating, (15), Fig. 2 (not shown), provided close to the detecting plane, may have a periodic spacing a little different from that of the incident fringes, to act as a vernier and to allow detectors of bigger size and spacing to be used. Alternatively the third grating may have the same periodic spacing as the fringes but be skewed a little to provide MoirÚ fringes. In a further embodiment Fig. 3, part of the space between the gratings 1 and 3 is filled with a block 17 to reduce the risk of contamination of the gratings in e.g. a machine-tool environment. A second lens 16 between the index grating 3 and the detectors 8-11 may image the lamp filament at the detector plane; but the lens 16 may be omitted if the gratings 1, 3 have different pitches.

Title: Improvements in or relating to machine milking installations

IPC: G05D9/12
Filed: 1964-08-27
Abstract: 1,091,231. Automatic quantity control. ALFA-LAVAL CO. Ltd. Aug.27, 1965 [Aug.27, 1964], No.35156/64. Heading G3R. In a milking installation in which the quantity of milk collected in a vessel under vacuum is automatically maintained between limits by periodic operation of a draw-off pump in dependence on the quantity of milk in the vessel, auxiliary driving means also responsive to the quantity in the vessel are provided for coupling to the pump in an emergency. In the machine milking installation to which the invention is applied, milk is collected under vaccum in an interceptor vessel having electrodes at different levels, or a float or weight operated switch, so that, whenever the quantity of milk reaches an upper limit, operation of an A. C. motor-driven pump is initiated. Milk is then withdrawn until the quantity in the vessel falls to a lower limit. An auxiliary D. C. motor for the pump is arranged together with its operating relay in a housing which, in the event of a mains failure, may be attached to the base of the A. C. motor-driven pump by hook bolts. Leads are provided from the housing for connection to an accumulator and the auxiliary motor shaft has a flexible coupling which may be attached to the A. C. motor shaft. Leads from the quantity detector associated with the interceptor vessel are connected to sockets on the housing so that the D. C. motor, instead of the A. C. motor, controls the pump.

Abstract: 367,453. Mixing fluids in flow ; valves. MARIGNY, H. G. and PEMBERTON, R. T., Aldwych House, Aldwych, London. Nov. 22, 1930, No. 35248. [Class 86.] Apparatus for adding measured quantities of reagents to water comprises electrical means controlled by the flow of water and actuating the reagent supply. The water flows to a mixing tank through a meter which periodically closes a contact in a relay circuit controlling an electromagnet or motor which actuates an admission valve for the reagent. The diluted reagent is fed into the mixing tank by a pump operated by a motor the starting switch of which is controlled, through a relay, from a mercury switch operated by the flow of water, the supply of diluted reagent being thus stopped with that of the water. The water is supplied by a pump 1 through a main 2 fitted with a meter 3, to a mixing tank 4. The meter 3 comprises a contact the closing of which energizes an electromagnet 13 forming a relay in the circuit of a second magnet 15, or a motor, operating a dosing valve 10 controlling the supply of reagent to a tank 8 to which water is fed through a pipe 9, the jet being directed on to the valve to clean it. The diluted reagent is fed from the tank 8 to the mixing tank 4 by a motor-operated pump 6, a return pipe 19 and valve 20 being fitted so that the contents of the tank 8 may be circulated to secure effective mixing before starting the apparatus. The starting switch 16 of the motor is controlled by a further electromagnet 14 in the circuit of which is a mercury switch 22 operated by connections with the main 2 on opposite sides of a constriction 23. The reagent tank is fitted with a stirrer 18 operated from the motor, and the valve is shielded by a gauze cage 25. The mixing tank discharges into a settling tank 17.

Crimped conjugate polyamide filaments are produced by simultaneously and concurrently melt extruding through the same spinneret orifice a Nylon 6 (or a copolymer consisting chiefly of nylon 6) and a nylon 11 (or a copolymer consisting chiefly of nylon 11) to form a conjugate filament of either the side-by-side or sheath-core type, drawing the conjugate filament and subjecting the conjugate filament to a heat treatment whereby the conjugate filaments become crimped. The drawing of the filaments may be effected at a draw ratio within the range 3:1 to 4:1, preferably 3À6 : 1 to 3À8 : :1. The melt temperatures of both the polymers being spun may. be within the range 220 to 270‹ C.

Abstract: 955,588. Cleaning centrifuges. E. L. ALFORD. Sept. 17, 1962, No. 35354/62. Heading B2P. A washing unit for cleaning the discs 51 of a centrifugal cream separator comprises an elongated horizontal tank 15 in the interior of which the discs are received within a submerging charge of cleansing liquid which is introduced into the tank by means of nozzles 28, 30 disposed on a substantially common horizontal plane intermediate of the tank and at mutually spaced points along longitudinal liquid supply lines at the opposite sides of the tank at an angle to the longitudinal axis thereof so as to direct the cleansing liquid in the form of pressure jets towards the discharge outlet end 20 and against the discs 51, the cleansing liquid being circulated from the tank interior to the nozzles by means of pumps 33, 34 connected to the discharge end through pipes 31, 32 and delivering the cleansing liquid to the nozzles through manifold pipes 27, 29 extending externally of the tank sides. The tank has an open top. The discs are nested on a perforated tubular member 62, blanked off at one end and coupled at the other to one end of the pipe 27 whereby cleansing liquid is discharged radially between the discs. The disc assembly is supported in the tank on a rack structure 64. Water together with a detergent and/or disinfectant are first introduced into the tank through inwardly directed nozzles 42 extending from a manifold pipe 43 having branches extending along the tank sides and connected through a three-way valve 44 with supply pipes 45, 46 for optionally providing hot water or steam at the nozzles 42, the steam serving to maintain the charge of cleansing liquid at the required temperature. The supply of liquid is ascertained by a thermometer 47. The detergent and/or disinfectant may alternatively be added directly to the tank over its side. The tank may be drained at the end of a cleaning operation through a valve-controlled pipe 24. Alternatively, when elements of a cream separator which are required to be cleaned are fixedly positioned in the tank by gravity, a nozzle 26, Fig. 1, may be connected to the end of pipe 27 to direct cleansing fluid longitudinally of the tank against the elements.
