Title: Improvements in or relating to centrifugal pumps and blowers, and radial-flow turbines
IPC: F04D29/22
Filed: 1956-11-20
Abstract: 842,262. Centrifugal pumps and blowers; turbines. SKOGLUND & OLSON A.B. Nov. 20, 1956 [Jan. 13, 1956], No. 35504/56. Classes 110 (1) and 110 (3). In a rotor for a centrifugal pump or blower or a radial-flow turbine, the blades merge at their inlet end with an inner cylindrical wall and concentric with the axis of rotation, the impeller inlet being divided into an inner circular port within the inner cylindrical wall and an outer annular port between the inner and an outer cylindrical wall so as to provide inner and outer series of channels having their outlet ends arranged to alternate one with the other. The inner wall 20 of the centrifugal pump impeller shown in Fig. 1, changes from its initial cylindrical form at the inlet to the form shown in Fig. 3, subsequently dividing into three separate walls 26, Fig. 4, which become kinked as in Fig. 5, and eventually divide into separate walls 5, 6, Fig. 6, extending between the outer cylindrical wall 21 of the impeller and the back plate 23. The walls 5, 6 eventually become parallel to the axis of rotation at the impeller outlet. Thus, there are provided three channels 27, 28, 29, having a common annular inlet bounded by the walls 20, 21, and alternating with three channels 30, 31, 32 having a common circular inlet bounded by the wall 20. The pump is suitable for pumping thick, viscous or solid-carrying fluids.

Title: Solid electrolyte cells
IPC: C01G5/00
Filed: 1972-08-02
Abstract: 1395085 Solid electrolytes WESTERN ELECTRIC CO Inc 2 Aug 1972 [2 Aug 1971] 35984/72 Heading C1A [Also in Division H1] A solid electrolyte MAg 4 I 5  is produced by crystallization from a solution comprising an oxygen containing substituted solvent, silver iodide, XI as a source of iodide ions in which X is other than M or Ag and MI in which M is either Rb, K, NH 4  or Cs and in which the molar ratio of Ag and M is 4 : 1 so that the solid electrolyte formed is essentially MAg 4 I 5 . The solvent, which is suitably an alcohol, an ether or a ketone is selected such that its molar solubility limit for MI is at least 10 times its molar solubility limit for AgI. The crystallization is effected by reducing the temperature of the solution or by evaporating the solvent.

Title: Liquid dispensing apparatus
IPC: F16K21/20
Filed: 1958-11-10
Abstract: 846,214. Filling tanks &c. OIL EQUIPMENT MFG. CO. Nov. 10, 1958 [Dec. 18, 1957], No. 36091/58. Class 21. [Also in Group XXIX] With a main valve 34, Fig. 4, and a pilot valve 47 both seated, an inlet 16 connected to a source of pressure liquid, and an outlet 18 connected to a container to be filled, the liquid in the casing part 11 flows into the space behind the valve 34 via an adjustable bleed plug 27. Upon the operator turning a handle 70, Fig. 3, and a shaft 17 fixed thereto a crank 63 coupled to the latter by a ball clutch'is rocked to bring a roller 64 into contact with a head 48, Fig. 4, on the pilot-valve shaft 41 whereby the pilot valve 47 is unseated from the main valve 34 against a spring 46 enabling the liquid from behind the valve 34 to drain to the outlet since the flow capacity of the pilot valve seat 36 is greater than that of the plug 27; upon continued motion of the shaft 17 the head 48 engages the stem 40 of the main valve and gradually lifts the latter until the main valve uncovers by-passes 32 which interconnect the spaces on either side of the main valve and enables the shaft 17 to rapidly move the main valve to the fully opened position wherein it may be held or latched. The actuation of the ball clutch is controlled by a stepped plunger 56, Fig. 3, attached to a diaphragm 82 the rear side of which is connected to both a tube depending into the container whereby the liquid level therein is detected, and a source of vacuum generated, for example, by the liquid flow across the end of an opening in the main valve seat 15. Upon the liquid in the container covering the end of the tube leading to the diaphragm the vacuum is enabled to move the latter and hence the plunger 56 whereby the shaft 17 is unclutched from the crank 63 and permits the spring 46 to rock the crank 63 and roller 64 downwardly and seat the pilot valve 47 whereupon liquid passes through the by-passes 32 into the space behind the main valve 34 to cause rapid movement of this valve toward its seat; when valve 34 has travelled sufficiently far to close the inner ends of the bypasses the final movement of the valve onto its seat is slow since liquid must now pass to the rear of the valve via the bleed plug 27. During the valve closing period the vacuum behind the diaphragm 82 will reduce and cause the latter and the plunger 56 to return inwardly to re-engage the ball clutch if the handle 70 is in the unoperative position; however if the handle 70 is latched in the open position the plunger 56 will not move until the handle is returned to the inoperative position.

Abstract: 1299677 Dental aspiration apparatus PENNWALT CORP 2 Aug 1971 [6 Aug 1970] 36289/71 Heading A5R A dental evacuation apparatus comprises a plurality of separate suction devices for removing debris from a patient's mouth, e.g. a cuspidor, an aspirator and a saliva ejector, a separator 26 common to said devices and having separate discharge ports for gas, liquid and solids, separate suction lines 20, 24, and 22 (Fig. 5) connecting each suction device to the separator, a venturi 28, 32, 30 in each of said suction lines, a compressed air line 44, 48, 46 connected to each venturi for supplying compressed air thereto, thereby to apply suction to the respective suction device, a valve 38, 42, 40 in each compressed air line for controlling the supply of compressed air to each venturi, and a compressed air bleed line connecting each compressed air line to the others, whereby, upon opening any one of said valves to supply a major flow of compressed air to the corresponding venturi, a minor flow of compressed air is supplied to each of the other venturis thereby to apply a minor suction to their respective suction devices. Debris extracted from the patient's mouth enters the separator 26 via discharge line 86 which terminate with curved portions disposed parallel to and adjacent the inner surface of the separator, the debris swirling around the inner surface. Liquids and solids descend while air or gas rises passing through a conduit 72, 73, 74 and a filter 76 to the atmosphere. Liquids exit the separator via a discharge line 100 and any air or gas entrained in the liquid is vented to the atmosphere via a passageway 102 and the filter 76. Solids settle within the receptacle portion 92 of a cap 90 threadably mounted on the separator, the cap 90 being provided with a circumferential channel 98 to prevent during removal of the cap spillage of any liquid which has collected below the level of the discharge line 100. Removal of a suction device from its holder in the dental unit will actuate the flow control valve associated therewith.

Abstract: 772,419. Frictionally-damped resilient mountings. BARRY CONTROLS, Inc. Dec. 29, 1955 [Jan. 17, 1955], No. 37245/55. Class 108(3). A vibration isolator comprises a housing 45 into which extends a load attachment member 46 supported within the housing 45 by two conical springs 51, 52, arranged with their smaller ends acting in opposite directions against a portion of the member 46, and their larger ends acting respectively against the opposite ends of the housing 45, the springs 51, 52 being partially compressed in the unloaded position of the member 46, means being provided for friction-damping of relative movement between the member 46 and the housing 45. As shown the springs 51, 52 are of rubber. A friction damping element 54 is urged by a spring washer 55 into contact with a washer 57 carried by the member 46. The periphery of the member 54 is formed into an annular groove to accommodate a spring 61. The periphery of the disc 54 is slotted radially so that it is in the form of a series of resilient fingers. In operation, lateral movement of the member 46 is frictionally damped by relative movement between the element 54 and the washer 48. Axial movement of the member 46 is damped by frictional engagement of the peripheral fingers of the element 54 with the sides of the housing 45. In a modification, Figs. 1 and 2 (not shown), the springs 51, 52 are replaced by respective conicallywound coil springs. The large diameter end of each coil spring bears on the respective end face of the housing 45 through the intermediary of a resilient. abutment washer formed of nylon. The element 54 in this construction is of nylon and instead of being formed with peripheral resilient fingers the element 54 is divided diametrically into two halves.
