Filed: 1967-06-29
Abstract: 1,188,368. Counters. H. MULLER and S. MULLER, [trading as J. HENGSTLER, K. G. ZAHLERFABRIK]. 29 June, 1967 [21 Jan., 1967], No. 29983/67. Heading G4D. Operation of a setting key to adjust a presettable counter is ineffective unless the counter has first been restored. With the reset yoke 3 inoperative, depression of a setting key 5 brings the left-hand side of pivoted pawl 6 against the end 9 of a bridge 8, so that the pawl 6 is swung into clockwise position, where it is held by a spring-pressed ball detent 7. The pawl 6 is thereby held clear of the associated numeral wheel 1. If, however, the counter is first restored by operation of yoke 3, which cams bridge 8 counter-clockwise then the pawl 6 remains in its counter-clockwise position and engages the teeth 2 of the numeral wheel when the setting key 5 is depressed. In a modification (Figs. 6-12, not shown) the pawl may be movable horizontally into or out of the path of the teeth of the numeral wheel.

Title: Method for making vacuum enclosures for electric discharge devices
IPC: H01J9/385
Filed: 1955-10-21
Abstract: 820,066. Discharge tubes. GENERAL ELECTRIC CO. Oct. 21, 1955 [Oct. 22, 1954], No. 30119/55. Class 39(1). [Also in Group XXXVI] The envelope of a discharge device consists of alternate metal and insulating members separated by metal shims, the whole being heated in vacuo below the melting point of the shim/metal member alloy to outgas the envelope parts and activate the cathode, and then above said melting point so that the shims bond the envelope parts together; the metal members and the shims (or vice-versa) are formed respectively from the groups titanium - zirconium - hafnium - thorium and iron-nickel-cobalt-chromiummolybdenum-platinum-copper. The shims may be corrugated to facilitate evacuation of the discharge device. Fig. 2 shows a triode with anode 10, grid 11 and support 16, and cathode 12. An end closure disc 22 acts as a terminal for the heater 21. The cathode 12 is connected with the metal ring 18 by a conductive coating on the ceramic ring 17. Suitable metals are titanium for the envelope parts 16, 18, 22 and nickel for the shims 24, or vice-versa ; the titanium also acts as a getter. In such an arrangement, the device is heated to 900‹C., which degasses the parts, and activates the cathode. Further heating to 1000‹C. causes the titanium and nickel to melt and alloy, which alloy also wets and bonds with the ceramic part. Fig. 3 (not shown) is an apparatus for performing the sealing operation, the envelope assemblies being gripped between spring-loaded supports inside an oven, the whole being surrounded by an evacuable bell-jar over which fits an inductionheating coil. Several discharge tubes may be thus fabricated simultaneously. Specifications 813,829 and 820,068 [both in Group XXXVI] are referred to.

Abstract: 1,224,780. Screwing - up tools. CHARLES CHURCHILL Ltd. 25 June, 1969 [26 June, 1968], No. 30356/68. Heading B3N. [Also in Division B8] An apparatus for automatic application to work of screws, nuts &c., comprises a pivoted holder 13 normally positioned between camcontrolled jaws 17 to receive an object e.g. released from an escapement mechanism 12 described in Specification 1,224,779, a cam 21, normally maintaining the jaws 17 open, operable to cause the jaws to close on an object when held in the holder 13, the holder thereafter being movable from its position between the jaws, to release the object and the jaws being movable to carry the object towards the work, apply it to the work and thereafter, under the action of the cam, to release the object, and an applicator tool 30 for completing application of the object to the work. After receiving a screw, an automatic screwdriver proceeds to screw the screw into a workpiece. A shaft 22, rotated by a pneumatic turbine 28, is lowered by a pneumatic piston-and-cylinder arrangement 24, 25 whereby the cam 21, supported at the lower end of the shaft by a circlip 42, is caused to enter jaw recesses 44 whereby the jaws 17 close under the action of springs 20 to grip the screw. During downward movement of the shaft 22 a roller 45 engages a cam-face 46 on the holderarm 14 to pivot the holder 13 from between the jaws, thereby releasing the screw. Thereafter, a member 26 carried by the upper end of the shaft 22 abuts the upper end of a sleeve 32, and, through a spring 31 imparts downward movement to a sleeve 19 surrounding shaft 22. The jaws 17, carried by sleeve 19, the shaft 22, and bit 30 move downwards together until a collar 33 on the sleeve 19 abuts a stop 47 to arrest movement of the sleeve 19 and jaws, continued downward movement of the shaft compressing spring 31. Cam 21 is then forced downwardly out of recesses 44 to open the jaws to release the screw into a tapped hole in the work. The final descent of the rotating bit 30 screws the screw home. Reversal of the motion of the piston-andcylinder arrangement 24, 25 at the upper and lower limits of jaw movement is via tripswitches 36, 37. The holder 13 may, alternatively, receive nuts to be screwed on to a male screw-thread, the bit 30 then being replaced by a blind female socket.

Filed: 1922-11-07
Abstract: 209,535. McKean, J. G., and Jones, R. F. Nov. 7, 1922. Gills for tubes: casings; tubes of special section.-Heat exchange apparatus in which a triangular shaped chamber contains a number of tubes with fins thereon, is constructed with the fins attached to or integral with the tubes or with spacing strips between the tubes, and arranged so that the fins on adjacent tubes or strips do not overlap. The fins may all line up or adjacent rows may be in staggered relation, and are circular or polygonal in form. Tubes 1, Fig. 1, with hexagonal fins 2 are carried on end plates in a chamber 5 of triangular section. The tubes are in staggered rows, and the fins are hexagonal and integral with or secured to the tubes. The fins preferably form complete transverse walls with intermediate spaces and may be staggered so that the fins on one tube are opposite the spaces on the adjacent tubes. In a modification, the rows of horizontal tubes are inclined, and the spaces between the outer fins and the side walls are filled with strips or tubes of soft material. The tubes may be reduced in diameter where they pass through the tube plates. Instead of straight tubes, field tubes may be used, the outer element having fins. When relatively large closely pitched tubes are used, the fins 11 with outer circular edges are formed on rods 10, Fig. 8 and act as spacing members. The chambers 5 mav be externally of cylindrical form and provided with walls 14, Fig. 6, to form the triangular chamber 15.

Title: Inflatable bladder liquid dispensers
IPC: G01F11/08
Filed: 1973-06-26
Abstract: 1397898 Delivering measured quantities of liquid CHEMECH ENG Ltd 26 June 1973 30440/73 Heading B8N A liquid dispenser comprises a measuring instrument, Fig. 1, and a pneumaticallyactuated dispensing head valve, Fig. 2, the spherical measuring vessel 10 of the measuring instrument containing an inflatable bladder 11 and being made by fixing two plastic mouldings together along a joint line which is in a plane containing the centreline of the vessel. The measuring instrument consists of liquid inlet and outlets 16, 22 adjacent non-return flap valves 17, 20, a compressed air connection 13 and pressure switches 28, 36. The liquid outlet 22 is connected to the inlet 43 of the dispensing head valve disposed above the measuring instrument. In operation, the liquid fills the vessel 10 and when a pressure of 3 lb./in.<SP>2</SP> is reached to operate the pressure switch 36, this closes electrical contacts to permit an electric current to flow to a solenoid-operated air valve in a control box 40 provided a manually-operated pushbutton adjacent the dispensing head valve has been operated to initiate a dispensing cycle. The compressed air is supplied to the inlet 44 on the dispensing head valve to lift the valve 45 and to the inlet 13 of the bladder 11 so that the liquid is pushed from the vessel 10 by the inflating bladder up to the dispensing head valve for delivery through an outlet 42. This air pressure is such that the liquid pressure at the top of the vessel 10 is more than 35 lb./in.<SP>2</SP> as the bladder is inflating. When the bladder is fully inflated, the liquid pressure at the top of the vessel above the non-return valve 20 drops to equal the static head of liquid due to the height of the dispensing valve head above the measuring instrument. This head is equivalent to less than 35 lb./in.<SP>2</SP>, the pressure at which the pressure switch 28 is set to operate. This drop in pressure then opens the electrical contacts to cause the solenoid operated air valve to shut off the supply of air to the dispensing head valve and the bladder and allow the dispensing head valve to close and the bladder 11 to deflate under the pressure of the new supply of liquid through the inlet 16. The pressure switch 36 again prevents operation of the push-button until the vessel has refilled and attained a pressure above 3 lb./in.<SP>2</SP>
