The loose bottles are supported on stationary tracks 17, 18 and workable track bars 19 below the conveyer. The track bars 19 are situated below a cleansing zone. The conveyer progressively advances each row of bottles step-by-step from positions below one row of nozzles 23 to similar positions below the next adjacent row of nozzles. The track bars 19 are detachably mounted by pivots 26 in arcuate recesses 27 on transverse bars 25, Fig. 7, and each has an operating arm 28 extending downwardly from one of its ends The arms 28 each have recesses 29 to detachably receive pairs 30 carried by a reciprocable bar 31. The bar 31 is supported by hangers 32 pivoted at 33 to the side walls 13, 14. The bar 31 is reciprocated by a connecting rod 36, from a driven shaft 37 through a clutch (see Group XXIV), sprockets and a chain, and a shaft having a crank pin 35 connected to the rod 36. When the clutch is disengaged by an operating handle 49, a forked member 54 on the handle causes the crank pin 35 to be secured in either its highest or lowest positions which correspond with the intermediate horizontal positions of the track bars 19 (see also Group XXIV). The track bars 19 when so secured form smooth tracks to form continuations of the fixed tracks 17, 18. In Fig. 7, a bottle 16 is shown in full lines supported on the track bar 19 in its intermediate or mid position and in dotted lines supported on the track bar in one of its two extreme tilted positions. When the outer margin of the bottle engages with the outer margin of the track bar, the forking of the bottle ensures efficient cleansing. The bottle holders 15 comprise pushing abutments 57 and deflectors 58, Figs. 8 and 9. Fig. 8 shows a bottle being pushed along a track bar 19 in its mid horizontal position while Fig. 9 shows the bottle deflected from the abutment 57 when the bar is rocked. This deflection causes the bottle to perform a slight rolling motion.

Filed: 1964-04-10
Abstract: 1,067,585. Coatings. ING. A. MAURER S. A. April 10, 1964 [April 11, 1963], No. 14948/ 64. Heading B2E. [Also in Divisions B5 and D1] A process for the production of a smooth uniform thermoplastic coating on a carrier web comprises the steps of casting an incompletely homogeneous coating from a heterogeneous mixture, as hereinafter defined, on the surface of a heated roller, and subjecting said coating to pressure over an area defined by the surface of a heated homogenisation carrier web which the coating is in contact to complete homogenisation of the coating, By the term hetergeneous mixture as applied to the starting materials is meant for example, an only slightly stirred mixture of granulate or powder of a thermoplastic material and plasticiser, if desired, together with fillers and/or colourants or the like, in which the solid particles are only partly wetted, or a granulate or powder of thermoplastic synthetic resins of the same or different kind without additives, the heterogeneity of these pure granulates or powders only consisting of the physical continuity of the mass. The pressure on the coating may be exerted by the carrier web, forming a concave surfacce moving in the same direction against the surface of the roller as is the roller thereby effectirig complete homogenisation of the coating. Said web is urged toward the heated roller by two auxiliary rollers which are mounted against the circumference of the heated roller. The concave surface may move at a speed greater than the circumferential speed of the heated roller, and the difference in speed between the surface of the roller and the concave surface may be such as to produce a frictional force corresponding to 2 to 20 times the layer strength of the molten coating. Suitably, the coating is of a thermoplastic synthetic resin e.g. polyethylene, polypropylene, polyvinyl chloride, polystyrene and co-polymers thereof. In Fig. 2. molten coating S is pressed by carrier web 10 which is to be coated, over sector # on calender roll 3. The carrier web must here be subjected to tension and withstand certain tensile stresses so that is it possible to exert pressure over the whole peripheral area of roller 3, defined by angle #, as a result of which the homogenisation can be effected in a manner according to the invention. A modification can be made in the apparatus shown in Fig. 3, so that coating of a web and homogenisation can be effected at the same time by running a carrier web between the elastic roller 13 and the melt S. In Fig. 4, an apparatus is shown in which the coating is effected of a roller 11 at the point 1' by means of a doctor blade 12 which may be heated. Coating S is pressed by auxiliary rollers 5, 6 and 7 against the peripheral area of roller 11 defined by angle 8 by means of a tensioned metal band 9. In this embodiment of the invention, which has only one roller, an elastic roller, as shown in Fig. 3, can also be used to replace rollers 5 and 6 when it is desired to exert pressure by a carrier web to be coated, as shown in Fig. 2.

Abstract: 929,251. Secret transmissions. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING A.G. April 26, 1961 [April 28, 1960], No. 15077/61. Class 40 (4). Signals are secretly transmitted by modifying them to render their amplitude constant and reversing their phase at random intervals according to a predetermined programme. At the transmitter 1 (Fig. 1) the speech signals e1 are sampled at 3, the instantaneous voltages e2 being passed to an amplifier-limiter 4 which produces voltages of constant amplitude. These are applied to a ring modulator 5 which also receives from a scrambling apparatus 6 an irregular sequence of positive and negative pulses e6 (Fig. 4) under the control of punched cards or a magnetic tape. As a result the phase of the constant amplitude samples is changed at irregular intervals so that the voltages e4 (Fig. 3) are transmitted. These, if rectified, would produce a constant direct current. The transmitted voltages e4 pass via channel 9 to a ring modulator 7 at the receiver 2, and control signals e7 pass via channel 10 to control the scrambling apparatus 8 in synchronism with that (6) at the transmitter. If desired, the channel 10 may be dispensed with, the scrambling apparatus 6 and 8 being controlled by means of a computer as described in Specification 873,277. The sampling operation may occur before or after the phase reversal, and the amplifier-limiter may be located before, between, or after the sampler and the phase reverser.

Abstract: 1492411 Measuring thickness: measuring resistivity UNITED KINGDOM ATOMIC ENERGY AUTHORITY 12 April 1976 [11 April 1975]  15087/75 Headings GIN and G1U In a system for determining two parameters r and t of a test object which are not directly measurable from two parameters R and I which are directly measurable, three standard test objects in the first of which both r and t are a minimum, in the second r is a minimum and t a maximum, and in the third r is a maximum and t a minimum, are sensed in turn and the resulting three pairs of values of R and I, namely (X, Y), (C, D), and (E, F) are recorded, (see Fig. 2, in which the vertical axis for I is labelled 'WWLL'), an unknown object is then tested and from the values (g, h) of its parameters R and I, and the previously stored reference data, its parameters r and t are calculated. As described the parameter r is the resistivity of a conductive block of material 12, Fig. 1, carrying an insulating coating 11 of thickness t. The parameters R and I are the real and imaginary components of the impedance of a sensing coil 13, these values being derived by a detector 15 from the sensing coil when driven 14 by a fixed frequency. The parameters r and t are derived, as described, from the parameters R and I by assuming that r and t are each linear functions, over the range in question, of R and I. Further, the actual formulae used produce values of r and t from the sensed values (g, h) of R and I with respect to a scale in which the minimum values of r and t (i.e. those of the first standard object) are zero, and the maximum values are unity. In a modification the maximum values are 1,000. The technique may be applied to detecting flows in aircraft panels where the scale is calibrated with respect to a standard size hole drilled in a test panel which represents a crack to be found. Another test piece is used which has no defect and a third has no crack in a panel which is thinner due to corrosion. The apparatus is set to detect a crack and to detect thinning of the panel independently.

Title: Improvements in or relating to cocks and valves
IPC: F16K7/16
Filed: 1921-05-31
Abstract: 184,911. Milner, H. L., and Beeby, A. R.. May 31, 1921. Lift valves; diaphragm valves.-In a valve or cock of the type in which a flexible valve member e in the form of a chamber or diaphragm is first moved towards its seat and the final closure effected by the fluid pressure expanding or flexing the valve member, a normally closed aperture j in the valve member is opened by the initial closing operation, to admit the pressure fluid. In the form shown in Fig. 1, a cap b in screw arrangement with the outside of the main casing a controls the closure of the valve e, of rubber or other material, on its seat at the end of the portion c of the casing. The valve e is held in a cap or container f closed at its back, and spun over at its edge f<1> to pinch the valve e and to hold in place, or itself form, a guard ring g or may be arranged in the head of the cap b. In the closure oooration the head of the screw h which is normally held by fluid pressure against the valve e is moved therefrom by the flexing of the diaphragm e as it comes into contact with the casing c and allows the pressure fluid to enter behind the valve e and effect a tight final closure by the unbalanced pressure. The abutment of the container f on the casing at a<3> prevents the valve from being damaged by undue mechanical pressure. In another modification shown in Fig. 2, the hole i<1> in the valve chamber e<1> may be placed eccentrically to prevent closure when the wall of the chamber is flexed inwards by contact with the seating
