Patent GB-2120576-A (GB)
Title: Wet separator for and method of purifying polluted conditioning air
Inventor: ENEROTH JAN-MATS
IPC: B05B14/46
Filed: 1983-05-19
Abstract: A wet separator for purifying polluted conditioning air and separating solid and semi-liquid particles therefrom, especially paint particles in the outlet of a spray painting booth. For this purpose, there is a series of outlets with surfaces converging in the direction of flow into a neck or throat which increases the speed of passing media and thus achieves mixing of air, water and pollutants. According to the invention, beyond the first outlet in the direction of flow there is a dispersing chamber for further mixing and atomizing the mixture, which chamber terminates in the direction of flow in the second outlet, which is designed as a venturi with a more extensively throttled venturi opening defined by a flange extending into said opening. The outlets may be interconnected by a guiding surface, on which a dispersing stream of water droplets, air and pollutions impinge with a flat angle of impact adjacent to the second outlet at the lower end of the guiding surface. The impact area provides a special disintegration zone in front of the second outlet serving as a sound absorbing cover. Alternatively intermediate outlets may cause tortuous flow through the dispersing chamber providing an extended path which retards transmission of noise from the final outlet back to the booth.
Patent GB-2141234-A (GB)
Title: Eddy-current flaw detector
Inventor: MALOV VYACHESLAV MIKHAILOVICH
IPC: G01N27/90
Filed: 1983-06-07
Abstract: An eddy-current flaw detector comprises an eddy-current transducer (1) whose inductance coil (2) is inserted in the oscillatory circuit of a self-excited oscillator (3) electrically connected to the input of a threshold detector (14). The output of the detector (14) is connected to a flaw indicator (15) and to the input of an autotuning channel (16) composed of such series-connected components as a controllable pulse generator (17), a control switch (18), a pulse counter (19) and a digital-to-analog converter (20). The output of the channel (16) is connected to the control input of the self-excited generator (3). The autotuning channel (16) enables the detector to work consistently in testing diverse materials. In a setting mode, the transducer (1) is placed on a flawless surface, and the autotuning channel (16) is activated to bring the oscillator (3) to a condition of oscillation close to quenching. The autotuning channel (16) is then locked, and subsequent passage of the transducer over a flaw will quench the oscillation. Advantageously the output of the autotuning channel (16) may also be used to control the gain of an amplifier (21) in the detection channel. <IMAGE>

Title: Improvements in or relating to anti-skid brake pressure regulating systems for vehicles
Inventor: RUDIGER DR FRANK
IPC: B60T8/46
Filed: 1983-12-08
Abstract: To reduce yaw effects in a vehicle having an anti-skid brake pressure regulating system (2, 7-10), a simple short-circuit or by- pass line (15) is provided between the two passage outlets of a brake pressure-regulating valve (2), or between the outlets of two single valves (Fig. 2 not shown) so that any differences in pressure in the two brake circuits can be equalized e.g. when one brake is released to prevent locking. The system can be used both in compressed air-brake systems and in hydraulic brake systems of vehicles. <IMAGE>

Title: Comminution of material
Inventor: ADAMA ROGER WILLIAM
IPC: B02C23/06
Filed: 1985-08-01
Abstract: Material is comminuted in a substantially dry state in a chamber (4) as a result of agitation by a rotor. During the process, gas is admitted to the chamber (4) through a foraminous base (8) to flow upwardly in a uniform manner across the cross-section of the chamber. Pulses of gas are directed periodical­ly at the material through inlets (15) to prevent agglomeration of the material. The pressure of the gas admitted through the inlets (15) is higher than that admitted through the foraminous base (8). Surface active agents may be added to the material, also to prevent agglomeration, as well as, or instead of the use of pulsed gas.

Title: Rotating liner hanger and running tool
Inventor: WHITE PAT M
IPC: E21B33/14
Filed: 1986-01-23
Abstract: Running tool 50 releasably connects hanger 35 (consisting of tube 36 composed of a plurality of sections 36a to 36c) to workstring in a first position (Figure 40) with connector means 56 releasably engaging threads 59 in section 36b and snap ring 65 locating in groove 66. In this condition, the tool 50 can both rotate the hanger or move it axially, and the hanger 35 is lowered by the workstring to the desired depth in a well casing where the workstring is manipulated to release a slip carrier from 9 J-slot connector. Lowering of workstring 47 then causes expander 28 to force slip means 23 firmly to engage with the well casing to arrest tube 36, whereafter snap ring 65 disengages from groove 66 and engages an upper groove (not shown). Workstring 47 is now raised to move fingers 62 out of their recesses 150 and until shoulder 55a abuts nut 56, whereupon rotation of workstring 47 disengages nut 56 from the tube 36 after which the workstring 47 is free to move axially within the hanger 35, and is lowered to re-engage the fingers 62. Now, the running tool 50 can only rotate with its attached liner, bearing assembly 70, comprising alternating thrust washers and support rings permitting this during cementing operations to obtain the advantages known to be achieved by such rotation. <IMAGE>

Patent GB-2181550-A (GB)
Title: Mounting system for precision transducer
Inventor: NORLING BRIAN L
IPC: G01P1/02
Filed: 1985-11-27
Abstract: Most prior mounting systems for accelerometers have been noncompliant and have therefore resulted in stress being applied to the transducer due to differential thermal expansion. This limitation is overcome by the mounting system of the present invention that is adapted to support a precision transducer (14) in spaced alignment with a supporting case (12). The mounting system comprises a plurality of mounting elements (30), each mounting element having a first end (34), a second end (32) and a resilient intermediate portion (36). The first end is connected to the transducer, and the second end is connected to the case. The first ends of adjacent mounting elements are preferably joined to one another by bridge sections (38) to form a continuous mounting ring (16), and the second ends of adjacent mounting elements are preferably separated by gaps (56). At least the first ends and bridge sections are composed of a substance that has a coefficient of thermal expansion approximately equal to the coefficient of thermal expansion of the transducer. Each intermediate portion is adapted to provide a low resistance to relative movement between the transducer and case in a radial direction, and a high resistance to relative movement in other directions. The mounting system therefore securely mounts the transducer against rotation and overall translation, while being compliant with respect to differential thermal expansion.
