Title: Improvements in or relating to amplitude sensitive circuit arrangements
IPC: H03F1/54
Filed: 1959-04-15
Abstract: 886,971. Circuits for gramophone reproduction. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 15, 1959 [April 18, 1958], No. 12810/59. Class 40 (4). [Also in Group XL (c)] A circuit arrangement suitable for indicating overload in a radio receiver or gramophone amplifier comprises two valves, a common input for supplying an input signal to the two control grids, a low anode voltage supply for the second valve, the second valve being biased to cut-off by a bias which is developed across the cathode resistor of the first valve and applied to the cathode of the second, whereby, on the occurrence of a peak of predetermined amplitude at the input the second valve is made conducting. In the Figure, the detector 7 of a radio receiver is shown feeding a tuning indicator 17 and an audio amplifier 10, the amplifier 10 driving the triode 16 output stage. An additional triode 15 has a common grid and cathode connection with triode 16. A low-voltage anode supply for triode 15 is derived from resistors 19, 22, so that the cathode bias keeps the valve normally cutoff, and the output is connected to the grid of a tuning indicator 17 via capacitor 21. When the positive half-cycle of the audio waveform reaches an amplitude at which the grid of valve 16 is driven to zero or positive with respect to cathode, valve 15 conducts and produces a signal across resistor 19. This signal is applied to the tuning indicator 17 to be superimposed as a flutter on the visual tuning signal. The signal output from valve 15 may be alternatively applied to the grid of the tuning indicator by a transformer.

Abstract: 706,003. Coating with metals. BRITISH AMERICAN RESEARCH, Ltd., PIRANI, M., and WHITELAW, S. B. April 6, 1950 [May 18, 1949], No. 13241/49. Class 82 (2) [Also in Group XL (a)] Articles, such as lamp reflectors are coated from evaporation and/or spluttering sources within an evacuated chamber by effecting the simultaneous coating of a plurality of the articles in a number of cells arranged in units movable individually into a common vacuum chamber, corresponding parts of the cells in each unit being all in the same plane, and the units being so disposed in the chamber that each plane containing corresponding parts of the cells in the same unit is parallel to the planes containing corresponding parts of the cells in other units, each cell having at least one evaporation and/or spluttering source located within the cell. The cells may have six or more faces or may be substantially spherical. According to the Provisional Specification the cells can be in the form of octahedra. One arrangement is furnished by lattice structure consisting of straight metal frame members subdividing the evacuated space into cells as shown in Figs. 1 and 2. The cell 1, Fig 1, has the same number (six) of evaporation sources 2 as it has of faces, the sources being located within the cell. In order that the cells may be accessible they are arranged in slices 2-10, Fig. 2, each slice containtaining the cells between two parallel places spaced apart the width of one cell, the slices having two wheels and two sliding contacts which convey current to the evaporation source filaments which are connected in parallel or in series, the wheeled structure serving as a conductor if desired. The evaporation sources need not be filaments but may be formed as boats or troughs. In the arrangement shown in Figs. 4 and 5 the sub-division of the evacuated space into cells is achieved by a multiplicity of reflectors for coating, the concave faces of a pair of opposed reflectors forming the walls of a cell, and a filament or evaporation or spluttering source being arranged between the reflectors of each pair. Gas molecules can escape through the openings 14 of the reflectors and through the gaps between opposed reflectors. Metal plates 15 are provided with holes of the size of the mouth opening of a reflector 13 and with hooks 23 to hold the reflectors. Insulating spaces on which holders for filaments 24 are fixed may be interposed between each pair of plates 15. The plates 15 can be used as conductors if the filaments 24 are in parallel but if the filaments are in independent groups insulated wire connections are arranged. Handles 25 are attached to the plates 15.

The conveyer for moving the racks 25 through the enclosure 10 comprises flexible members 43 (Fig. 2, not shown) on which are suspended rods carrying dog members adapted to engage parts of the racks 25, the rods being oscillatable by crank mechanism. The apparatus shown in Fig. 1 has one conveyer 90 in the form of an endless chain passing around a drive sprocket 80 and idler sprockets 82, 84, 85, which guide the chain through a channel 100 alongside the enclosure 10. The pusher members 90 are provided in the upper link parts of the chain 90 as dimples, ridges or projecting screw heads. The drive sprocket 80 is driven by an electric motor 145 via a belt and pulley drive 146, 147, 144, reduction gearing 142, and a friction clutch 140 which slips should the conveyer chain 90 become jammed. The speed of the chain 90 is controlled by rotating a threaded shaft 157 to pivot the motor 145 about support pins 152, thereby changing the diameter of the adjustable sheave 146 in the belt and pulley drive. The sprocket 84 is supported on an arm 180 (Fig. 6, not shown) rotatable on the mounting of the sprocket 85 to adjust the tension of the conveyer chain 90. Waste particles are removed from the chain 90 by a water jet from a nozzle 114 (Fig. 13, not shown) disposed adjacent the chain between the sprockets 80, 82. The racks of washed dishes are normally removed from the apparatus at the table sections 52, 55, but if a rack is not removed it engages an arm 247 to operate a switch 248 to stop the conveyer 90. In an alternative embodiment two endless chain conveyers are provided, one at the entrance and the other at the exit of the washing enclosure in which an integral conveyer is provided.

Title: Improvements in and relating to a method of cleaning and/or disinfecting the milkingunits of milking machines, and an apparatus for carrying out the said method, and a mixing device for such apparatus
IPC: A01J7/02
Filed: 1959-04-20
Abstract: 876,386. Cleaning and/or disinfecting milking units. MIKKELSEN, A. K. April 20, 1959 [April 18, 1958], No. 13360/59. Class 138(1). [Also in Group XXVIII] Milking units, consisting of teat cups, central piece and associated milk hoses, are cleaned and/or disinfected by the continuous upward flow of milking machines of suitable liquid through the unit, air being continuously admitted into the liquid before the liquid flows into the milking unit at such a rate and with such a pressure that the ascending air is capable of ensuring the flow of liquid solely by entrainment thereof. A closed collecting tank 1 has connections for the airtight mounting of the teat cups 8 and an outlet 5 which is connected through a hose 6 with an open tank 13, e.g. a milk pail, containing the cleaning liquid 14. The teat cups 8 are connected by short milk hoses 9, with the central piece 10 from which the main milk hose 11 leads, to a mixing device 12 which, in the embodiment illustrated in Fig. 1, consists of a U-tube placed in the open tank 13. One branch 12a of the U-tube is open to the atmosphere while the central portion 12c is provided with bores 15 through which the cleaning liquid 14 can flow. The apparatus is connected to the vacuum line of the milking plant by means of the outlet 4 and the valve 3 adjusted so that the pressure within the tank 1 is reduced to a vacuum corresponding to a static negative pressure head slightly smaller than the vertical distance between the surface of the cleaning liquid 14 and the bottom of the tank 1. This is indicated by the surface 16 of the liquid column in the return hose 6. Air is thus sucked in through the inlet 12a and conveys the cleaning liquid flowing in through the bores 15 in a strongly turbulent flow through the milking unit into the tank 1, from which the air escapes through the outlet 4, while the liquid returns through the hose 6 to the tank 13. Instead of the several bores 15, an oblong slot may be used, Fig. 3, and surrounded by a longitudinally displaceable sleeve 17 so as to regulate the ratio of air to liquid in the mixture passing into the main milk hose 11. As shown in Fig. 3, the mouth of the tube 18 which extends downstream of the slot 15 functions as an ejector nozzle which is of particular importance if the inlet end of the tube 18 is connected to a compressed air source, e.g. the pressure side of the vacuum pump belonging to the milking plant. In this case the outlet 4 of the tank 1 is open to the atmosphere or, if a greater difference in air pressure be desired, is connected to a vacuum.
