IPC: F15B15/10
Filed: 1960-04-08
Abstract: 898,923. Machine tool details. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 6, 1961 [April 8, 1960], No. 12534/60. Class 83 (3). [Also in Groups XXIX, XXXI and XXXIV] An hydraulic drive arrangement for a member 11, Fig. 2, such as the tool carrier of a machine tool, supported for sliding motion on a supporting member 12 comprises a liquid chamber 15 which is formed between the adjacent bearing surfaces of the members 11, 12 and is of small dimension in a direction normal to the bearing surfaces so that liquid fed to the chamber 15 passes through it in the form of a thin layer and driving movement is imparted to the member 11 by the force exerted by the liquid due to its viscosity and skin friction drag upon the walls of the chamber. The member 11 may be formed with two chambers 15, 16 and liquid is supplied from a pump 20 to chamber 15 to move the member in the direction of arrow A or to chamber 16 to move the member in the direction of arrow B. Valves may be provided at the inlets or outlets of the chamber to control the movement of the member. In another embodiment, the chamber 24, Fig. 3, extends substantially the whole length of the member 21 and the supply from the pump 28 is directed to one end or the other of the chamber to effect movement of the member 21, which may be formed with chambers on opposite sides of the supporting member 21 to prevent separation of the surfaces. In a further embodiment for rotating a shaft 51, Fig. 5, the chamber 53 is formed in a housing 52 and fluid is supplied from a pump 57 to one end or the other of the chamber to rotate the shaft in one direction or the other. In a similar arrangement, a wheel 61, Fig. 6, such as a vehicle wheel, is supported on a stub shaft 62 and fluid supplied from a pump 67 to the chamber 63 through a passage 65 or 66 rotates the wheel in one direction or the other. Further passages 68, 69, 70 are connected by a passage 71 to atmosphere or suitable control means to relieve pressure at a bearing area 64 so that the wheel is supported on the liquid as in the ease of a hydrostatic bearing.

Title: An improved interval meter
IPC: G01S1/72
Filed: 1942-09-05
Abstract: 554,816. Echo-sounding and distancemeasuring apparatus; short-tune meters. HUGHES & SON, Ltd., H. (Dannell, A. G.). Sept. 5, 1942, No. 12555. [Class 118 (ii)] [Also in Group XVIII] An interval meter, particularly intended for use in the measurement of distances by echosounding, comprises a light-transmitting bar which is moving during the sending of a signal and the reception of the echo, and scales to show the amount of movement during the interval. The meter comprises a cylindrical casing 16 within which a coaxial drum 17 is rotated at constant speed by an electric motor 12. An electric lamp 10 is situated at the axis of the drum 17, and a bar 21 of transparent material extends radially from a point adjacent to the lamp through a slot 20 in the rim of the drum. As the drum rotates, the outer end of the bar passes close to elongated slots 26, 29 in the casing 16, graduated scales 32 being marked beside the slots. When the lamp is alight, the sides and end of the bar 21 are illuminated by internal reflection and are seen as lines of light in the slots 26, 29. The drum carries an electric contact 30 which makes contact with another, 31, on the casing at the moment the outer end of the bar is adjacent to the zero position of the scales 32. The contacts then complete the circuit of a transmitter which sends out a signal sound. Reception of the echo by a suitable receiver is arranged either to cause the lamp 10 to flash, or to extinguish the lighted lamps. In the former case, a line of light is seen momentarily through the slots 26, 29 and the distance to be measured can be read off the scales 32. In the latter case, an area of illumination extends along the slots 26, 29 from the zero to a variable point which indicates the distance. In a modified construction, two bars 21 extending in opposite directions are used to enable indicating scales to be provided on both sides of the meter.

Abstract: 1,111,114. Sampling liquids. COMMISSARIAT A L'ENERGIE ATOMIQUE. 22 March, 1966 [26 March, 1965], No. 12682/66. Heading B8N. [Also in Division B4] A sampling device for radioactive liquid as shown in Figs. 1 and 2 comprises means 48 for introducing an empty sample pot 6 to a first station 36, pot-carrying means, such as an arm 20 operated by a jack 14, for transferring the pot to a second station 2 where the sample is taken and then transferring the pot to a third station 38, and means 62 for ejecting the filled pot from the arm at the third station. The pot 6 to be filled is introduced on to the first station 36 through a retractable tube 48. The piston 18 of the jack is operated by fluid through a pipeline 26 and when the piston is in its uppermost position, a key 30 emerges from a mouthpiece 24 to allow rotation by a handle 22. The arm 20 is lowered on to the first station 36 and the pot gripped by lipped-type packing in a recess in the end of the arm. The arm is then raised and rotated to the second station 2 where the pot is lowered on to a needle 4 which penetrates a stopper 47 to fill the pot with the liquid sample, the stopper being made of an elastomer which recloses on to itself after the pot has been withdrawn from the needle. The pot is then conveyed to a position above the third station 38 and the pot ejected from the arm into a container 58 by a retractable push-rod 62. A slidable trap door 66 in the base of the device is then opened for emptying the pot through a conduit 68. The push-rod 62 and its sleeve 60 is replaced by a tube similar to the tube 48 for loading the container into the third station 38. The device is sheathed with lead and provided with an inspection porthole 10 covered with lead glass, a mirror 80 and lighting system 82. The device is supported by a plate 88 and may be connected to a probe bottle (90), Fig. 4 (not shown), in which the lower end of the needle (4) is immersed. The bottle is connected via a deflector (92) and filter (94) with either atmosphere (95) or a vacuum system (97). Vacuum in the bottle causes liquid to be drawn up from a reservoir through a tube (91) and at a certain level the liquid closes an electrical contact for connecting the bottle with atmosphere. Some of the liquid enters the pot (6) through the needle. The process is repeated until the desired amount of sample is taken, the pot then being raised automatically by the arm.
