Filed: 1919-02-20
Abstract: 140,179. Crabtree, J. A. Feb. 20, 1919. Snap-action switches.-In a switch of the type in which the pivoted operating-member and pivoted contact member have pivotally coupled to them a spring element at positions eccentric to their respective axes, stopping-means, engaged by a non-current carrying part of the contact member which moves in a direction away from the switch base, are provided for limiting the movement of the contact member both in its closing and opening operations. In the arrangement shown in Fig. 1 for a tumbler switch, the operating-tumbler 1 and the contact-carrying member 3 are pivoted on a common axis. A plunger pin 8 pivoted on the tumbler lever works within a sleeve 7 pivoted on the contact member, and a, compression spring 9 is arranged around the pin and sleeve and is compressed during the operating movement until the dead-centre is passed, whereupon the spring produces a quick action. The contact-carrying member is formed with two shoulders 11, one or other of which, at the limit of the angular upward movement which it makes away from the base in the switching on or switching off operation, engages the under edge 12 of the bridge 2, or an integral extension thereof, or a striking-plate secured thereto, which stops the contact member. The invention is applicable to a two-way switch, and the shoulders may engage the bridge at an angle. The means for producing an initial movement of the switch, described in Specification 140,180, may be employed.

Title: Improvements relating to intermittent driving mechanism especially for filtering or thickening apparatus
IPC: B01D35/00
Filed: 1937-02-12
Abstract: 487,351. Chain, belt, and rope gearing. DURANT, H. T. Feb. 12, 1937, No. 4307, [Class 80 (i)] Consists in intermittent driving mechanism particularly adapted for withdrawing a filter element from and returning it to a, tank of a filter or thickener, in which a continuously moving flexible element, chain, belt, or rope is caused to move an element first in one direction and, after an interval to move it in the reverse direction. A framework 1, Fig. 1, supports shafts of sprocket wheels 2 .. 7 around which passes an endless chain 8. The sprocket wheels 5, 6, of which 6 is mounted on the shaft 10 to be driven, each comprises a central fast sprocket 12, Fig. 4, by the side of which are loose sprockets 11, 13. The chain 8 consists of two parallel runs, Fig. 3, which engage the sprockets 11, 13 and one or more inserts 9 adapted to engage, at intervals, the fast sprocket 12. The sprockets 2, 3, 4, 7 are merely idlers. instead of a chain, a belt or rope with projections or knots may be employed. A countershaft 16 and the shaft 10 of the driven sprockets 5, 6 are connected by a chain 17 on sprockets at the side of 5 and 6, so that when one of these shafts is rotated, the other is also rotated. Assuming the chain &c., which is driven by a motor 15, to be moving in the direction of arrow A, and that the insert 9 is located at a, b, nothing happens until this insert engages the central sprocket of member 5 which is then rotated anticlockwise and this movement is transmitted by the chain 17 to the member 6, so that the filter element 20, on the shaft 10, is withdrawn from the tank 22. When the insert leaves the member 5, an interval of rest occurs, during which the element 20 can be cleaned by rollers 24. When the insert 9 reaches the central sprocket of the member 6 this member is now rotated clockwise, and the member 20 returned to the tank. The actual drive of the members 5, 6 by the insert 9 may be in the same direction, the chain 17 then being crossed, and the driving chain passing around both members 5, 6 in the same direction. The movement of the driven member in one direction may be caused to be different from that in the other by adjusting the are of contact of the chain &c. Further, the drive may be positive for only a part of the movement, the element continuing by its own momentum. The element 20 is connected by means of a manifold valve and flexible piping to a vacuum pump 23. An agitating worm 25 is located in the bottom of the tank. In a modification, a sprocket on the shaft 10, is connected by a chain or belt to a pulley supporting a leaf filter which is moved vertically into and out of the tank, the filter being held at the top of its stroke by a band brake actuated by the insert 9. A battery of filtering units may be actuated by the chain 8. The shaft 10 may, in the above arrangements, be extended laterally in both directions to carry a number of filtering elements 20.

Title: Improvements in and relating to high voltage fuses
IPC: H01H85/00
Filed: 1944-03-08
Abstract: 577,363. Fusible cut-outs. BRITISH THOMSON-HOUSTON CO., Ltd. March 8, 1944, No. 4314. Convention date, March 11, 1943. [Class 38 (i)] A high-current fuse comprises a glass or ceramic casing 10, containing a granular arcquenching material 21, in which is embedded a star-shaped core 12 carrying a fusible spirally-wound conductor 14, connected to the end-caps 11. The conductor 14 consists of the long wires 15 which are adapted to fuse over a considerable length and are connected by low melting-point solder 18 to the thermal storage bodies 16 connected together by a resistor 19. On sustained overcurrents insufficient to fuse the wires 15, enough heat is generated by the resistor and accumulated in the storage bodies to melt the soldered connections 18 and interrupt the circuit. In a modification, a single wire, resistor and storage body may be used, and the supporting core omitted. Where a long delay in fusing is tolerable the low-melting-point solder may be dispensed with and the wire directly connected to the thermal storage body.

Title: Apparatus for forming and coneying stacks of flat workpieces
IPC: B31B50/98
Filed: 1973-01-29
Abstract: 1391573 Stacking and conveying flat bags, sacks, &c WINDMOLLER & HOLSCHER 29 Jan 1973 [12 Feb 1972] 4433/73 Heading B8C In an apparatus for forming, and conveying, stacks of flat workpieces W such as bags, or sacks, the latter are delivered, one at a time, by a supply conveyer 22 on to a step-by-step, vertically-movable, belt conveyer 1 where they are arrested by a stop 15 which is in its lowered operative position the conveyer 1 being automatically lowered by a step each time the build up of workpieces W thereon is sufficient for an arriving workpiece W to actuate a feeler 15 on the stop 2 until the required number of workpieces has been registered on a counter 21 whereupon a switch 17 is operated to start the belt drive of the conveyer 1, commence the return of the latter to its elevated position, and raise the stop 2. Since a discharge belt conveyer 3, hinged at 10 to the conveyer 1, is simultaneously started, the completed stack St is discharged while the conveyer 1 is being raised the conveyer 1 being stopped when an abutment 19 operates the switch 17. The stop 2 is lowered again into its operative position after the trailing edge of the completed stack St has released a feeler 20. The stop 2, and the feeler 20, are individually adjustable in the horizontal direction to accommodate stacks of various sizes. If a workpiece is incorrectly fed on to the conveyer 1 it actuates a sensor 27 which causes the stop 2 to be raised and a jack 11 to be operated so that the downstream end of the conveyer 3 is lowered as the conveyer 1 is started and is moved to its lowermost position the partially-formed stack being delivered to a table 9 instead of to a conveyer 8 leading to a processing machine. After all of the workpieces forming a stack have been fed to the table 9 they can be fed back to the supply conveyer 22.

Patent GB-1101731-A (GB)
Title: Coating of glass
IPC: C03B40/00
Filed: 1965-02-03
Abstract: A thin tightly-adherent colourless coating of SnO2 is formed on the surface of virgin glass, or metal which is used for conveying the virgin glass, by exposing the metal or glass surface at 900-1500 DEG F. to an atmosphere, including SnCl2 vapour in the presence of oxygen.  The atmosphere can contain 0.01-2.5% weight SnCl2.  The glass article, e.g. sheet, container or tubing, can be advanced through the atmosphere, e.g. on a conveyer (see Figs. 1-10, not shown).  The atmosphere can be generated by passing a gas, e.g. moisture-free air, N2 or A over or through liquid SnCl4.  The concentration of the latter can be altered by varying the temperature of the liquid or by altering the flow rate of the carrier gas or by introducing further carrier gas or by mixing an inert liquid with the SnCl2.  Only a portion of the glass article, e.g. the neck of a container, need be coated (see Figs. 6-10).  The SnO2-coated glass can also be coated with stearates and polyvinyl alcohol reaction products. The SnO2 coating can be applied by mixing SnCl2 vapour with gas and air and burning in a gas flame burner (see Figs. 11 and 12 (not shown).

Title: Improvements relating to endless band conveyors
Inventor: SUTTON FRED RICHARD
IPC: A21B5/02
Filed: 1949-02-21
Abstract: 657,605. Endless-belt conveyers. BAKER PERKINS, Ltd. Feb. 21, 1949, No. 4647. [Class 78 (i)] Two conveyers, one of which is an endless wire mesh band, are maintained in alignment by means which includes one or more toothed wheels, the teeth of which mesh with the wire band at a position between its edges, the toothed wheel or wheels being operatively connected to the other conveyer so as to transmit tracking movements of the wire band to this other conveyer. Dough shapes are delivered from a panning conveyerband 1 to the receiving end of a wire mesh ovenband 4. The panning band 1 passes over a knife-edge 6 and is mounted in a frame 2. The frame 2 at its remote end, not shown, is mounted for oscillation about a vertical pivot, as described in Specification 472,270. Alternatively, frame 2 may be fixed and the knife-edge 6 mounted for movement. The moving part, i.e. frame 2, as shown, carries a pair of arms 5, one on each side, which support at their forward 'ends a shaft 9, the height of which can be adjusted by means of nuts 8. A double arm crank 10 is freely mounted on the shaft 9 between two collars and carries at its ends two sprocket wheels 11 or preferably two groups of sprocket-wheels so as to provide a number of rows of teeth. The teeth engage the underside of the wire mesh band between its edges. The position may be changed by adjusting the collars along shaft 9 from time to time to reduce overall wear, a number of locking-holes being provided in the shaft for this purpose. Fine adjustment to line the teeth with the mesh pattern is carried out by loosening grub screws 14 holding the ends of the shaft 9 and moving the shaft axially, then re-securing. Instead of a fixed vertical adjustment by means of the nuts 8 the sprockets 11 may be spring-pressed against the underside of wire band 4.

Filed: 1919-02-25
Abstract: 136,721. Allcock, A. T. Feb. 25, 1919. Curve - describing instruments. - An instrument for obtaining approximately involute curves for the teeth of gearing comprises two straight-edges A, B inclined at an angle equal to the complement of the angle of pressure of the gearing. The edge A is graduated in units of length, and the edge B is graduated in such a manner that a line, such as OR, joining corresponding graduations is inclined to the edge A at an angle of which the cosine is equal to the cosine of the angle of pressure divided by 1.0595. To use the instrument, the edge A is laid along the pitch radius with the point P on the pitch circle M. Then, if OP represents the pitch radius, the face and the root of the tooth are obtained by describing circular arcs with centres R and S respectively, PS being equal to PR/2. The instrument may have additional edges A<1>, B<1> inclined at an angle to correspond with a different angle of pressure, or it may be formed as a trapezium in which opposite corners enclose different angles. The blades B may be made detachable from the blade A.
