Abstract: 1445061 Gas stream cleaning BECKMAN INSTRUMENTS INC 5 Aug 1974 [29 Aug 1973] 34376/74 Heading BIT Solids are separated from a gas stream 26 by returning a proportion 24 of the gas stream against the main flow 26 whereby a "dynamic screen" is formed, e.g. in an inlet probe 12. A pump 14 draws gas through inlet probe 12, a minor proportion (clean gas) passes through throttle valve 18 and the major proportion e.g. 38% is passed through branch 21 and is ejected concentrically against the indrawn gas. In Fig. 2 the inner of the two concentric tubes in the nlet tube and the annulus between the two walls contains the flow cycled back to form the "dynamic screen". The apparatus may be used for separating solids from flue gas prior to analysis, (e.g. as illustrated in the drawings) or stack gases of chemical plants carrying catalyst residues, magnesium oxide, and acid mists.

Abstract: 966,094. Hydraulic apparatus. TAYLOR WOODROW CONSTRUCTION Ltd. Oct. 3, 1961 [Oct. 7, 1960], No. 34488/60. Heading F1P. [Also in Division E1] An hydraulic control circuit for a pile driving/ extracting apparatus using hydraulic jacks 11 (see Division E1) comprises solenoid operated valves 28 which each control the movement of a jack. Four oil pumps 24 are located in pairs in reservoirs 25 and each pair serves four jacks 11. Amplifier valves 30 are provided to load the pumps 24 and are normally open when the apparatus is not in operation to pass oil back to the reservoirs 25. When it is required to operate selected jacks 11, to either drive or extract a pile, the solenoids on the valves 28 and 30 are energized from a control desk (not shown) to open valves in the pilot pressure circuits (shown chain-dotted) to act upon the valves 28 and 30. The selected valve 30 closes to stop oil being returned to the reservoir 25 and the valve or valves 28 open to operate the jack or jacks 11. Metering valves 31 provide speed control for the jacks 11 and relief valves 32 and 33 control the maximum working pressures. 35, 36 and 37 arc non-return valves and 38 incorporate orifices to control the rate at which oil is returned from the jacks 11 to the reservoirs 25. Pressure fluid can be directed to either side of any jack with any combination of jacks in operation simultaneously and jacks can be hydraulically locked whilst others are operated. The operation of the control valves may be manual or automatic.

PRYANISHNIKOVA. 10 July, 1969, No. 34723/69. Heading A1D. Liquid is injected into soil using pulse jets the nozzles of which are disposed above the soil, the pressure before the nozzles being not less than 100 atmospheres. Apparatus for injecting liquid into soil comprises a cylinder 5 having a nozzle 1, a plunger 9 and a means 17 for periodically connecting the rod 16 to the plunger. Liquid is supplied to the cylinder by the pipe 7 and the device is driven by the internal combustion engine 13, 14. The piston 13 is driven upwardly and lifts the rod 16 and the plunger 9. At the top of the stroke the device 17, Figs. 3 and 4 (not shown) disconnects the rod 16 from the plunger 9 which is driven downwardly by the spring 10. The beam 15, rod 16, and the engine piston then fall under the action of gravity and the spring 18 to compress air and fuel in the cylinder 14 in preparation for the next cycle. At the bottom of the stroke the rod 16 and the plunger 9 are reconnected and the cycle repeats. A ram 19 is provided to start the machine by lifting the beam 15 to the position at which the rod 16 and plunger 9 are disconnected by the device 17.

Title: Electrical switches
IPC: H01H25/06
Filed: 1972-07-26
Abstract: 1430076 Mechanical switches; mounting switches LUCAS ELECTRICAL CO Ltd 6 July 1973 [26 July 1972] 34871/72 Heading H1N A switch with a slidable and/or rotatable carrier of a movable contact has means for mounting it in an aperture in a panel which include an abutment surface non-perpendicular to the switch axis and which is deformable whereby the switch can be mounted in the panel by insertion from one side and secured in position by the mounting means without access to the other side of the panel. Thus the switch may be readily and horizontally mounted in an inclined panel. Three embodiments are described. In the first (Fig. 1) a flexible sleeve 16 having an inclined recess 18 is deformed to fit an aperture in sloping panel 32, and the switch body 10 is then inserted. This sleeve 16 can be readily substituted to accommodate various panel angles. Projections 33 (only one shown) limit the inward travel of the body 10 and a projection 20 on a resilient blade 21 enters aperture 19 in sleeve 16 to secure the switch body in position. A movable contact bridge 15 is secured to the inner end of a slidable and rotatable carrier 14 for co-operation with three contacts 11 integral with terminal tags 26, 27 and 28. A spring 31 urges the contact 15 to the left and a detent 24 co-operates with recesses 25 to locate the axial positions of carrier 14. Axial pull on a knob (not shown) on carrier 14 may close the circuit of vehicle side-lights while subsequent rotation additionally closes the headlight circuit. A gate (not shown) is provided to prevent direct movement to "sidelights off" position from the "headlights on" position. The switches of the other two embodiments function similarly but have a sliding contact action not requiring the spring 31. In Fig. 2, the front end 45 of body 40 is threaded and a nut 49 causes a wedge-like washer 48 to compress an annular flexible spring backing element 47 against an inclined shoulder 46, thereby expanding the element 47 to secure the switch in the panel 56. In the third embodiment the switch body (60, Fig. 3, not shown) is itself deformable (at 69) and is expanded by insertion of a washer (72) after snap-in abutment of an integral inclined front flange (68) against the panel (67).

The nut member may be secured to brace 12 by teeth 7 formed on the end of limb 1 and driven into a side surface (Fig. 4) or a top surface (Fig. 5, not shown) of the brace. Where the brace is of metal the teeth are omitted and the end of limb 1 is bent over twice as in Fig. 4, one of the bends being greater than 90 degrees, so that the nut member may be resiliently clipped on to the brace. Fig. 6 shows a nut member adapted to secure the leg 10 angled outwardly from the position shown in Fig. 4. The correct angle between the lower face of brace 12 and the upper face of leg 10 is ensured by means of a wedgeshaped spacer.
