Inventor: MENTINK LAURENTIUS ANDREAS GER
IPC: F15B21/02
Filed: 1996-05-31
Abstract: The invention relates to a hydraulic circuit for controlling a plurality of hydraulic motors, said circuit comprising a reservoir for hydraulic fluid, a pump connected therewith and driven by an electric motor, as well as a valve device for controlling the hydraulic fluid flow to the various motors. According to the invention an OR-valve is connected in parallel to a reversible pump connected to the reservoir via a suction shuttle valve, the output of said OR-valve being connected to the fluid inlet of at least one electro-valve, wherein each electro-valve is hydrau-lically connected with one input of at least two AND-valves, the other input of which is connected with a pump outlet, whereas the outputs of the AND-valves constitute either individual or combined control outputs towards a hydraulic motor. <IMAGE>

Abstract: 1,026,865. Colour television. INTERNATIONAL POLAROID CORPORATION. Oct. 29, 1962 [Nov. 2, 1961], No. 40814/62. Heading H4F. [Also in Division H1] A colour television receiver operates according to the "red-white" principle of colour reproduction. The receiver responds to signals representing red and green components of an original image and employs a cathode-ray tube having a screen formed with two phosphors, one of which produces red light in response to electron impingement of comparatively low energy and the other of which produces minus red (i.e. blue-green) light in response to electron impingement of comparatively high energy, the arrangement being such that only the red phosphor is excited in response to the " red " signal but both phosphors are excited in response to the " green " signal so as to produce white light. In a first embodiment of the invention, Fig. 2, the cathode-ray tube face plate 40a bears superposed minus-red and red phosphors 41a, 42a, and an assembly of closelyspaced but separate aluminium strips 43a. There are approximately 500 strips with a width equal to the spacing and comparable to the size of a focused electron beam. The tube is operated at an anode potential such that the electron energy is sufficient to penetrate and stimulate emission from both phosphors. However, when the beam impinges a metallic strip the energy is reduced to a value such that only the red phosphor is effectively excited. The tube may utilize a single electron gun which is modulated by the " red and green " signals alternately at dot, line or frame rate and the beam is scanned over the tube screen so as to impinge the aluminium strips when red light is to be produced in response to the " red " signal and to impinge between the aluminium strips when white light is to be produced in response to the " green " signal. For operation at the dot rate the aluminium strips are disposed transverse the raster line scan direction. In an alternative arrangement the tube utilizes two electron guns which are controlled separately by the " red " and " green " signals, the electron beams being arranged to be focused at points which are spaced apart so that common scanning control causes one beam to transverse the aluminium strips and the other to traverse the intervening spaces. In a second embodiment, Fig. 4 (not shown), the two phosphors are formed as normal continuous layers. The tube is provided with two guns which are arranged at suitable different cathode potentials with respect to the final anode so as to cause excitation respectively of one and both phosphors. Alternatively a single gun is provided, Fig. 5 (not shown), which is modulated alternately by the two colour signals whilst the anode potential is switched between values which cause energization of one and two phosphors. The phosphors layers are separated by a gold layer 77 which is thin enough to be light transmitting filter. Layers 76 may produce minus red light or white light the minus red component of which is filtered by layers 77.

Abstract: 1460261 Ink-drop printers A B DICK CO 10 Jan 1975 [14 Jan 1974] 1163/75 Heading G4H An ink-drop printer 20-38 used for printing bar codes on a substrate 40 incorporates means 42-54 for removing one or more drops immediately following the first of a stream of drops for printing each bar, so as to compensate for the effects of aerodynamic drag (Figs. 1-2, not shown). Since drop 1 has to travel through undisturbed air it is slowed relative to the immediately succeeding drops, resulting in a curved drop stream, or possibly the fusion of drops 1 and 2. Drops 2 and 3 are therefore left uncharged and fall into a collector 38, while drop 1 falls into alignment with drops 4-8 (of an 8-drop bar). This is achieved by applying a step voltage 56 (58 shows the prior art) to the charging electrodes 28, 30; voltage 56 is obtained from counter 50, converter 53 and summing amplifier 54, counter 50 being reset by data source 52, 46 at the start of each bar, and logic 44, 48 ensuring that each bar has no more than 8 drops.
