Title: Barometrically actuated switch
IPC: H01H35/30
Filed: 1945-11-26
Abstract: 608,630. Pressure gauges. BENDIX AVIATION CORPORATION. Nov. 26, 1945, No. 31880. Convention date, Aug. 29, 1944. [Class 106 (ii)] [Also in Group XXXVII] In barometrically-actuated switch mechanism having adjustable connections between an aneroid driving element and a driven element actuating a contact pointer arm moving over the switch, there is a first means for adjusting the driving element in the direction of its movement, a second means for adjusting the relative positions of the two elements in a direction perpendicular to the direction of movement of the driving element, and a third means for adjusting the relative positions of the two elements in a direction perpendicular to the first two adjustments. As shown, an aneroid capsule 12 moves a contact arm 28 over a switch assembly 30 to control a radio transmitter in circuit therewith transmitting sounds equivalent to the pressure readings from an observation balloon. The evacuated capsule 12 has a tubular stem 14 passing through an enlarged aperture in a casting 10 and is adjustably clamped in a split clamp 16 which is itself mounted on the casing for adjustment perpendicularly to the direction of the aneroid adjustment. The arm 28 is mounted on a pivot pin 96 carried by a U-shaped bracket 24 adjustable on the casting 10 in a direction parallel to the axis of the pivot 96. A stud on the driving end of the capsule 12 supports an arm 74 carrying a bimetallic element 72 engaging a driving extension 76 on the arm 28, the plane of the element 72 being inclined to the direction of travel of the stud 74, but perpendicular to the zero absolute pressure position 32 of the arm 28. The bimetallic element 72 is arranged to compensate for temperature variations and is urged by a spring 105, coiled on the pivot 96, into contact with the extension 76. Movement of the bracket 24 permits adjustment of leverage between elements 72, 76 for further temperature corrections. A screw 100 holding the open ends of the bracket 24 in position to support the pivot 96 has the same coefficient of expansion as the latter. The switch assembly 30 has alternate conducting and insulating segments mounted within the open ends of a U-shaped bracket 34 secured by the base to the casting 10, and can be adjusted by a screw 40, 44 mounted in the casting 10. On the open ends of the casting 10 are a guard 52 and a swingable arm 50 adapted to lift the contact arm 28 away from the assembly 30. A bracket 66 mounted on a stud 64 on the casting 10 supports the whole assembly and has a lip engaging a depending portion of the bracket 34.

Abstract: 341,915. Refining iron or steel. KRUPP AKT.-GES. FRIEDRICHALFRED-HœTTE, F., Rheinhausen, Niederrhein, Germany. Oct. 21, 1929, No. 31975. Convention date, June 18. Addition to 317,373, [Class 72, Iron &c.]. [Class 72.] The process of refining iron or steel by the introduction of water into the molten metal through pipes, claimed in the parent Specification, is carried out with ordinary pipes which prior to or during the refining operation are provided with a protective layer of liquid slag. A layer of slag may be applied and the pipe then dipped into the bath while the slag is still liquid, the protective layer being periodically renewed by raising the pipe nearly out of the bath so that slag from the bath adheres to the primary layer. The slag may be applied during the refining by spraying it on to the pipe or by passing the pipe loosely through the bottom of a hopper filled with liquid slag so that the slag runs down the pipe and coats it. Cast-iron reinforcing bars, a, b, c, Figs. 2, 3, 4, may be provided in the pipe, the bars being in contact with the pipes at a few points only. The pipe may be coiled and provided with a flattened outlet d, Fig. 5, to give a ribbon-shaped jet. The water may be introduced to the bath through a slagcoated billet of the material which is being refined provided with a longitudinal bore in one end of which is screwed a liquid supply pipe, further protection being obtained in this case owing to the high thermal capacity of the billet.

Title: Magnetic flux-current signal converting apparatus
IPC: G01R33/028
Filed: 1973-07-05
Abstract: 1374069 Controlled saturable reactors GAMMA MUVEK 5 July 1973 32051/73 Heading H3X [Also in Division G1] The position of a magnet 1, Fig. 1, in a magnetic circuit 2 is determined by detecting the flux established in the circuit by the magnet and then measuring the current which must be passed through a coil 3 on the circuit to cancel the flux. The flux detector comprises two or more saturable magnetic strips 4 placed in a gap in the circuit 2; the strips are fed with current pulses as described below from generator 5, and a signal is produced in a pick up winding 6 surrounding the strips. This signal depends on the magnitude of the flux, and is amplified and rectified at 7 so as to drive coil 3 to cancel the flux. The coil current is measured as the voltage across resistor 8. The magnet 1 may be coupled to a pressure, temperature or level sensor so that the resistor voltage is a measure of the sensor output. In Fig. 2 (not shown) the apparatus similarly produces an output representing the position of a linearly movable magnet. The current pulses are asymmetric, so that on one half cycle the strips saturate while on the other half cycle they do not. As a result there is a cyclic variation in their reluctance. The flux through the strips thus varies in a cyclic manner as their reluctance changes and this induces a signal in the pick up winding 6. The current flows through the two strips in opposite directions so that it does not induce a net spurious signal in winding 6.

Title: Improvements in labelling machines
IPC: B65C9/34
Filed: 1952-12-19
Abstract: 722,400. Labelling machines. BRAASTAD, E. Dec. 19, 1952, No. 32239/52. Class 73 In a machine for labelling articles such as bottles, a continuous label strip is fed to the labelling station by a feeding mechanism and an actuating arm 9 in the path of the article 14 is connected to the feeder 11 by a spring 26 so that movement of the article to the labelling station gives the impulse necessary for feeding the labelling strip. The feeder 11 is mounted on a channel member 5 which is pivoted to a stand 4. An arm 21 on the member 5 extends below the feeding station. When the arm 9 is depressed by the article 14a shearing member 23 on the member 5 passes near a knife 7 and cuts off a label 20 from the strip. The label wraps around the container as the latter is pressed down into a yielding labelling support formed by an endless band 15 supported on two pins 16, 17 and stretched by a leaf spring 19. After labelling the container is lifted and a spring 24 swings the channel member 5 back to its original position, a spring 25 returns the gripping member 11 and the spring 26 returns the arm 9. In an alternative embodiment a feed channel member 38 for the label strip 39 is pivotally supported at 40 to the frame 31. The labelling strip extends through an opening 45 in a plate 46 and projects over a labelling support formed by an endless band 35 kept taut by a spring 36. A bail-shaped actuating member 47 is attached to the bridge 38. When a container 48 is moved into contact with the band 35 it acts upon the bail 47 so that the bridge 38 swings into the position shown in Fig. 7 whereby the label 39 is cut off in the opening 45 by a knife on the bridge and a knife 50 on the plate 46. The label feeding mechanism comprises a runner 51 with gripping members 52, 53. The runner 51 is connected to the bail 47 by links 55, 56, 57 and 58. Undesirable feeding of the labelling strip 39 when the container 48 is situated at the labelling station or is moving therefrom is prevented by a peg 66 co-operating with the end 67 of a plate 63 (Fig. 7). The yielding belt 15, 35 may be replaced by a rigid support 35<SP>1</SP> (Fig. 9), the actuating member 47<SP>1</SP> extending upwardly through a cutout in the support.

Abstract: 1,182,977. Centrifugal separator. WESTFALIA SEPARATOR A.G. 13 July, 1967 [15 July, 1966], No. 32314/67. Heading B2P. In a centrifuge for separating water and solids from oil, e.g. insulating oil, the separated oil is discharged under pressure from the centrifuge drum 1 by means of a skimmer 8 into a collecting chamber 12 which is sealed from a collecting chamber 5 for the separated water and solids and from a supply chamber 15 for the mixture to be separated. Separation takes place at a temperature of approximately 80C. The water and solids are periodically discharged from the sludge chamber 2 into the chamber 5 through valve-controlled openings 4. The oil passes inwardly of separating plates 3 and overflows via channels 6 into a skimming chamber 7 and thence through the skimmer 8, a channel 9, an annular chamber 10 and bores 11 into the chamber 12 in the form of a spray so that any water still retained in the oil is evaporated due to the release of pressure and may be discharged through the top part of a pipe 16 not filled completely with oil and leading to a container for the purified oil from which the vapourized water escapes. The chamber 12 may be connected to atmosphere through one or more passages 17 for the discharge of vapourized water. The chamber may also be connected via a fitting 18 to a vacuum pump in order to increase the evaporation effect.

Title: Improvements in washing apparatus for pipettes or similar tubular articles
IPC: B01L99/00
Filed: 1948-12-14
Abstract: 657,574. Washing pipettes. WEISKOPF, E. C. Dec. 14, 1948, No. 32344. [Class 138(i)] Relates to a washing apparatus for pipettes or similar tubular articles comprising a liquid container provided with a liquid inlet and a plurality of liquid outlets, siphons being connected to the outlets for periodically discharging liquid from the container. A container 10, preferably cylindrical, housed within a jacket 42, has a liquid inlet 16, Fig. 2, and a plurality of liquid outlets 18. The outlets, which are located at the same level in the container, are of the same size and are larger than the inlet. Each outlet is connected to a siphon 20, each siphon being identical in size and discharging into a common outlet 26. The U-bends 30 of the siphons are connected by an equalizing tube 28 which is connected by a tube 32 to an opening 40 in the container situated above the level of the outlets 18. Pipettes P to be washed are carried, in a substantially vertical position in a rack 53, Fig. 2, comprising a bottom 54 which is formed of wire mesh or is otherwise perforated, side members 56 to which are secured rings 62 and a handle 60, which rack is insertable into the container. In operation liquid may be permitted to flow continuously through the inlet 16. When the level of the liquid in the container reaches a level above the U-bends, the liquid automatically flows out of the container, the tubes 28 and 32 causing the siphons 20 to act in unison. When the liquid level falls to the level of the opening 40 the siphons cease to function, the container is then refilled and the operation repeated. The discharge period is quicker than the filling period since the outlets 18 are larger than the inlet 16. During both periods the liquid flows through the pipettes and also around them.

Title: Improvements in or relating to the generation of electrical oscillations by thermionic valves
IPC: H03B7/04
Filed: 1921-12-02
Abstract: 172,320. Ges. f³r Drahtlose Telegraphie. Dec. 4, 1920, [Convention date]. Vacuum tubes. - A thermionic valve having a space-charge grid in addition to the usual grid is caused to generate oscillations by connecting oscillatory circuits C L, C1, L, in the circuits of the anode and of the space-charge grid. The main grid is directly connected to the filament. The action appears to depend on the full utilization of the electron emission from the filament, an increase in the potential of the spacecharge grid causing an increase in anode current and therefore a reduction of the electron current to the space-charge grid. A negative-resistance effect is thus produced in the circuit of the spacecharge grid.
