Title: Improved apparatus for performing test milking operations
Inventor: ATTERLING JOHN WILLIAM LENNART
IPC: A01J5/04
Filed: 1950-12-01
Abstract: 688,332. Sampling liquids. AKTIEBOLAGET MANUS. Dec. 1, 1950. No. 29492/50. Class 106 (v). [Also in Groups XIX and XXIX]. Apparatus for taking samples of milk comprises a receptable 1, 2 subjected to the vacuum of a milking machine and having within it means 61 for measuring the quantity of milk supplied to the receptacle and valve means 53, operated by the measuring means 61, for delivering to test tubes 13 positioned outside the receptacle a quantity of milk bearing a predetermined relation to the total quantity measured. The milk passes from a supply pipe 50 through de-aeration and filtering chamber 51 and a pipe 60' to a flow meter 61 comprising a pair of floats 64 in cylinders 62. The alternate filling and emptying of the cylinders 62 is controlled by a slide valve 69 in a cylinder 68 whose opposite ends are alternately connected to atmosphere and to a vacuum in the receptacle by another slide valve 81 (not shown) which is itself controlled by the rise and fall of the floats through toggle mechanism and a T-shaped lever 75 bearing on the tops of the floats. Movement of the slide valve intermittently rotates the measuring valve 53 by means of a lever 90 having a toothed segment engaging a pinion 95 on the valve so that a series of quantities of milk entering a pair of diametrically opposed pockets 55 in the valve is diverted from the filtering chamber 51 to an outlet 58, each quantity being directly proportional to the quantity passing through the meter. The test tubes 13 are contained under a sealed cover 14 in a removable carrier 12 and are engaged by recesses on a pair of discs 31, 32 on a hub 30 rotatable on a pin 29. A plug valve 19 connects the interior of the receptacle either to a vacuum pipe 21 or to atmosphere at 120 and is connected through a Geneva mechanism 40 to give a step-by-step rotation to a splined shaft 27 engaging the hub 30 so that a fresh test tube is brought below the outlet 58 and an opening 37 in the cover 14; the shaft 27 can be withdrawn upwards against a spring - 26 to allow insertion of the carrier. Indicator numbers on a flange 35 appear below a window 36 to show which test tube is being filled. Movement of the slide valve 69 also operates a barograph-type recorder 108 by means of a pawl and ratchet mechanism 96 geared to a rack 105 carrying a writing instrument 107. A spring- loaded piston in a cylinder 114 connected to the receptacle disengages the rack from its pinion 104 when the vacuum in the receptacle is released by operation of the valve 19 as the milking of each animal is complete, so that the writing instrument falls to its initial position; a' stamping device stamps a number on the record strip. Self-sealing test tubes may be employed, in which case they are contained in an evacuated chamber. Specification 653,064, [Group I], is referred to.

Title: Transmission and parking brake control system
IPC: B60W10/10
Filed: 1976-07-15
Abstract: 1506117 Change-speed gear control CATERPILLAR TRACTOR CO 15 July 1976 [4 Dec 1975] 29552/76 Heading F2D In a change-speed gear having a control lever 14 moved in a first plane 46 to select neutral or a drive condition, the lever 14 when moved in a plane transverse to the plane 46, from the neutral position N thereof, directly operates an actuator 100 for a parking brake without mechanical interconnecting linkwork. As shown in Fig. 2 the pivoting of the lever in the plane 46 about an axis 40 causes a shaft 32 to be rotated by bevel gears 52, 30 and so operates electrical switching for selecting the gears. To engage the parking brake the upper portion 42 of the lever is pivoted about a pivot 66 to operate valve 100 through an adjustable abutment assembly 94. The valve 100 is closed by this action to cut off an air supply to a brake valve to cut off an hydraulic supply holding the brake disengaged in opposition to spring means. A spring 78 has an over-centre action to bias the lever towards or away from the parking position P. The parking brake may alternatively be pressure engaged, spring disengaged. The gearing may be in an earthmover.

Title: A method of, and apparatus for, inspecting the shape of small objects
Inventor: WEST PATRICIA ANN
IPC: G01B11/00
Filed: 1968-06-21
Abstract: 1,242,574. Investigating shapes photoelectrically. SIRA INSTITUTE. June 23, 1969 [June 21, 1968], No.29668/68. Heading G1A. [Also in Division G2] An apparatus for ascertaining the uniformity of at least a portion of a small object 1 comprises a radiation source 5, a Fourier analyzer 40 for receiving an image formed by the radiation diffracted, reflected and/or scattered by the object the analyzer having means 8 for scanning said image at different scanning spatial frequencies and also having means 13-16 for producing an electrical signal indicative of at least part of the Fourier transform of the mean intensity of radiation in the image. As shown, light from a laser 5 is directed by a beam splitter 4 on to a test object 1, such as a cutting edge, and the returned light is focused by a lens 2 on to a variable slit 6. A variable aperture 3 restricts the angular deviation of the returned light, and a cylindrical lens 14 defocuses the image of the cutting edge. This latter image produced at the slit 6 is focussed on to a disc 8 having radial grating lines. This disc is rotatable, and in addition its axis is rotatable about the optical axis 22. Rotation of the disc axis from one point to another results in a change in the angle of inclination of the grating lines to the slit, i.e. a change of scanning spatial frequency of the image, the speed of rotation of the disc itself being constant. In this way at least part of the Fourier transform of the average intensity distribution in the image at the slit 6 may be obtained at a number of different spatial frequencies. Radiation transmitted through the disc 8 is focused on to a diffuser 12 whence it passes to a photo-electric device 13 whose output is filtered, amplified and displayed on an instrument 16. The disc axis 8 may be rotated continuously about the optical axis to give a continuous variation of output of instrument 16 against spatial frequency, and this variation is then compared with the response of a standard object. Alternatively, a limited number of spatial frequencies may be chosen at which to make this comparison. A further beam-splitter 30 allows the slit 6 to be observed to check that the optical system is focused correctly. The positions of the source 5, on the one hand, and the detection circuitry 13-16, on the other, may be reversed.

Abstract: 937,584. Winding stators of electric motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 9, 1962 [Aug. 17, 1961], No. 29729/61. Class 35. A coil winding machine has a shuttle which reciprocates, and rotates through a predetermined angle in opposite directions after successive reciprocating movements and comprises releasable wire clamping means, wire cutting means, actuating means for producing relative movement between said shuttle and said clamping means at the end of each winding operation, and control means for providing sequential operation of the clamping and cutting means and the said actuating means. The apparatus comprises a shuttle including a hollow spindle 2 and a head which has four wire feed nozzles 3. The wire clamping means for each wire is formed by a pivoted arm 5 which has a semi-circular recess 8 near the free end which co-operates with an abutment 13. The surface of the abutment is resilient and the recess and the abutment have complementary annular corrugations, the recess also includes a knife edge which cuts the wire after it is clamped. The pivot of each arm 5 passes through the base plate 7 and has secured to it on the underside of the plate a pinion which meshes with a gear-wheel 11. Attached to the gear-wheel is an arm 11 which is operated by pneumatic or hydraulic means to rotate the arms 5 to the chain-line positions shown in Fig. 1. Operation. The end of the wire extending from the feed-nozzle 3 (Fig. 4) is already clamped between one of the arms and its cooperating abutment. The shuttle is operated and applies turns of wire to a stator polepiece mounted on a platform 17. When the desired number of turns have been applied, the arms 5 are pivoted to their chain line positions and the shuttle is moved to a position below the base plate 7 so that the four wires occupy the positions marked " X " in Fig. 1. The arm 12 is then returned to its original position so that the arms 5 gather the respective wires, clamp them against the abutments and sever them so that the wound stator can be removed and the ends of the wires remaining are clamped ready for the next winding operation. The platform 17 may be part of an indexing device which automatically brings an empty stator to the winding position at the end of each cycle of operations. The actuation of the various parts of the machine may be produced by pneumatic or hydraulic means and a suitable sequencing control system. Specifications 937,585, 937,586 and 937,587 are referred to.

Abstract: 1508020 Coating composition for shell moulds STAUFFER CHEMICAL CO 17 July 1975 [18 July 1974] 30059/75 Headings C3T and C3N A coating composition for the preparation of shell moulds comprises a refractory material and a binder composition which is substantially free of water, the binder composition comprising a prehydrolysed silicate ester, an amino alcohol of the formula HORN(R<1>)2 in which R is a C1-C6 divalent hydrocarbon radical, and R<1> is hydrogen, an alkyl radical or a radical of the formula -ROH, and an organic solvent, the mol ratio of amino alcohol to silicate ester being from 1 : 1 to 10 : 1. The shell mould is prepared by coating a cleaned and etched expendable pattern with the coating composition having a SiO2 content of 10 to 35% wt. of the binder composition, stuccoing the coated pattern, air drying and repeating the above steps until a coating of the desired thickness is built up, then optionally applying a seal coat thereto, comprising a hydrolysed silicate ester, a refractory material and an organic solvent. The expendable pattern is then removed and the shell mould subsequently fired generally at 500-3000‹ C. Suitable silicate esters are "condensed" ethyl silicate, ethyl silicate "40" and those obtained by the hydrolysis and condensation of ethyl silicate "40". Suitable amino alcohols are mono-, di-, and tri-ethanolamine, monoisopropanolamine, 2-amino-butan-l-ol, 3- aminopropanol and 2 - dimethylamino - 2- methylpropan-1-ol. The preferred solvents have a B.Pt. below 250‹ C., e.g. aliphatic alcohols, ketones, aromatic hydrocarbons and glycol ethers and esters. Suitable refractories are the oxides and silicates of Si, Al, Zr, Zn, Mg, Cr and Ti; zeolites, molecular sieves and ion-exchange resins; zircon, grog, calcined clay, silica flour, sand and fused silica. The weight ratio of refractory material to binder may range from 4-100 : 1. A gelling accelerator, e.g.NH3, or an organic amine, may be added to the seal coating composition. The stability of the binder compositions may be improved by adding boron compounds, e.g. boric acid and alkyl borates or organic acids, e.g. C1-C10 monocarboxylic acids. In the examples a binder composition comprising (1) "condensed" ethyl silicate or ethyl silicate "40", (2) ethanol or ethylene glycol monoethylether, and (3) ethanolamine is mixed with zircon and fused silica and the resultant slurry coated on to an etched wax tree pattern for a shell mould, then stuccoed with a fused silica sand and air dried; the coating and stuccoing being repeated several times. The resulting coated pattern is optionally coated with a seal coat consisting of a slurry of a partially hydrolysed silicate binder, isopropyl alcohol, a fine fused silica flour and water, then stuccoed with a coarse fused silica flour; the coating and stuccoing being repeated several times. The shell mould is then dewaxed and fired at 1000‹ C.
