Title: A control system for hydraulic alloy operated appliances
IPC: E02F9/22
Filed: 1968-03-06
Abstract: 1,222,104. Excavators. ORENSTEIN-KOPPEL UND LUBECKER MASGHINENBAU A.G. 6 March, 1968 [10 March, 1967], No. 10912/68. Heading E1F. [Also in Division F1] A control system for an excavator (not shown) comprises two pumps 1, 2 each connected to an associated pre-set relief valve 16, 15 which delivers pressure-relieved hydraulic fluid through a check valve 17, 19 and through lines 18, 20 neutral-positioned slide valves 9, 10 controlling associated motors 3, 4, 5 to a common line 21 which passes successively through neutral-positioned slide valves 12, 14, 13 for controlling associated actuators 6, 8, 7 whereby on opening any of one of valves 12, 14, 13 the pressure-relieved output of both pumps becomes blocked resulting in closure of both relief valves 15, 16 thereby rendering the output pressure of both pumps available to a selected actuators 12, 13 or 14. Motors 3, 4 propel the excavator, motor 5 pivots it and actuators 6, 7, 8 serve to operate a jib, dip arm and grab respectively. In operation and with valves 9, 10, 11, 13, 14 in neutral operation of any one of valves 12, 13, 14 say valve 12 in either direction, e.g. to the left connects the pressure delivery line 26 of pump 1 through a branch line 27 to the upper end of actuator 6 the lower end of which is connected to reservoir 25. At the same time the delivery of pump 2 passes along lines 28, 29, 30, 31, check valve 32 and 33 and is added to the delivery of pump 1 to assist in supplying the actuator 6. If now valve 13 is also displaced in either direction, e.g. ito the left pump 2 instead of delivering to actuator 6 delivers to the underside of actuator 7. Similarly with valve 12, 14 in neutral and valve 13 open both pumps supply actuator 7 and with valves 12, 13 in neutral and valve 14 open both pumps supply actuator 8. Only two of the three actuators can operate together and even though all three valves 12, 13, 14 may be operated valves 12, 13 are connected to their respeotve pumps whilst valve 14 is starved.

Title: Improvements in or relating ot x-ray diagnosis apparatus
IPC: H05G1/08
Filed: 1959-03-31
Abstract: 908,604. Control systems for X-ray apparatus. SIEMENS-REINIGER-WERKE A.G. March 31, 1959 [April 1, 1958; April 18, 1958; May 17, 1958], No. 10926/59. Class 38 (4). [Also in Group XX] The current supplied to the X-ray tube of a diagnosis apparatus is so controlled that the power supplied to the tube at the beginning of an exposure is reduced during the exposure (" initial loading "); means are also provided for measuring the dosage received by the film during exposure, and for interrupting the exposure when a predetermined dose has been received. Fig. 2 shows a suitable circuit. X-rays from a tube 1 pass through an object 6 and an ionization measurement chamber 7 to a film 8 when the film has been exposed to a desired extent,- a cut-out 5 transmits a switching-off signal to the control device 4. The tube 1 is connected via a H.T. transformer 2 to a source of voltage when a contact 3 in the primary is closed by the control 4. The H.T. supply can be controlled by a tap 10 in a pre-transformer 9. The tube heater voltage is supplied from a transformer 11 whose primary includes a resistance 12 having two taps 13, 14 which are coupled to the tap 10. Before exposure, the smaller part of resistance 12 is connected via tap 13 and a closed contact 15 into the heater circuit, thus determining the initial current. At the beginning of exposure, contact 15 is opened as contact 3 closes, and an incandescent resistance 16 (which may be an ordinary lamp bulb) is brought into the heater circuit. As the lamp heats up, the emission current of the X-ray tube slowly decays to a predetermined final value. A coarse compensation for the alteration in the H.T. voltage due to a difference in tube current is provided by a variable resistance 19 in the pre-transformer circuit, which is controlled by a motor 20 controlled in turn from the device 4. Alternatively (Fig. 5, not shown), the resistance 19 can be replaced by an incandescent resistance which is switched into the pre-transformer circuit at the beginning of exposure by the control 4. To set the percentage of the initial maximum load at which the tube is to be operated, the percentage selector device shown in Fig. 6 is used. The knob 21, setting the tube voltage, is connected via a shaft 22 to a contact arm 23 which moves over a series of contacts 25, corresponding to movement of the tap 10. Also mounted on shaft 22 is the sun wheel 26 of a differential gear 27. A calibrated adjusting ring 28 can be set to the percentage of the maximum load at which it is desired to run the tube. Ring 28 is connected via shaft 29 to the shaft 30 for the two planet wheels 31, 32. The rotation of the sun wheel 33 thus represents the sum of the movements of knob 21 and ring 28, and is transmitted via guide pulleys 34, 35 to the taps 13, 14.

Title: Fluid cleaner
IPC: B04B1/04
Filed: 1962-03-23
Abstract: 966,153. Centrifugal separators. DOUGLAS AIRCRAFT CO. Inc. March 23, 1962 [April 18, 1961], No. 11188/62. Heading B2P. A fluid containing impurities is clarified in a centrifugal separator by introducing it in a pulley-driven rotor 34, Fig. 1, in which circumferentially-spaced radial vanes 72 arranged in a fluid inlet channel 70 simultaneously rotate the fluid at the same speed as that of the rotor and cause it to flow axially through annular passages 104, Fig. 3, formed adjacent the periphery of the rotor between cylindrical walls coaxial with the rotor, so that due to the action of centrifugal force impurities having a specific gravity different from that of the fluid are deposited on one or both of the walls of each passage. The rotor is made of two parts 46, 62 and 48, 68 which are brazed together and surrounded by a detachable cover 50. The member 46 of the upper part is rotatably supported by a ball bearing 54 on another tubular spindle member 36 which is secured to a fixed stand 24 and is secured to a stationary inner tubular spindle member 26 by diffuser vanes 38 extending across an annular outlet channel 40 between the members which communicate with an outlet channel 60 in the rotor. The channel 60 is provided with vanes 58 similar to the vanes 72. The member 48 of the lower rotor part is integral with the pulley 76 which is rotatably mounted by a ball bearing 76 on a stub shaft 29 secured by fins 28 to the lower end of the tubular member 26. The interior of the member 26, through which the fluid is fed, communicates with the channel 70. The passages 104 are formed between thin sheet metal rings 100 disposed between the cover 50 and the rotor members 62, 68. In operation, the heavier impurities are separated in the space 105 below the rings 100 and the fluid, having the same velocity as the rotor, passes with laminar flow between the rings where the finer impurities are removed. The clean fluid then flows through the vanes 58 which function as turbine blades and recover a portion of the energy used to drive pumping vanes 72. The inner ends of the vanes 58 may be extended, cut back or bent to produce any desired condition of velocity and pressure in the fluid as it flows towards the exit 42 through the channel 40. The diffuser vanes 38 change all or part of the velocity head into pressure head. The separator may be cleaned periodically by removing the cover 50 and blowing through or flushing the stack of rings 100. The separator may be thermally insulated or operated in a cold chamber to purify liquid oxygen. It may also be used to clean fuels, oils and gases.
