Title: Improvements relating to the shaping of clay-ware
Inventor: JOHNSON JOHN ARTHUR
IPC: B28B1/02
Filed: 1953-12-12
Abstract: 765,097. Shaping clay-ware. SERVICE (ENGINEERS), Ltd. Dec. 10, 1954 [Dec. 12, 1953], No. 34658/53. Class 87(2). A piece of clay 22 is shaped to form a plate or saucer on a mould 21, carried by a rotating jigger head 20, by means of a rotating roller 25 which is progressively tilted over to shape the clay, until its shaping face is wholly in engagement with the clay. The tilting may start as the roller engages the clay or the roller may be tilted slightly before engaging the clay. The roller is mounted to rotate in a frame 33 and is driven by a motor 32 through a belt 29. The frame is pivoted about an axis B4 to allow the roller to be lowered to engage the clay by a cam 40 which acts on a roller 39 on an extension 33b of the frame 33. The relative position of the mould and the roller are so adjusted by adjusting the height of the jigger head (see Fig. 4, not shown) that, when the roller engages the clay, its axis of rotation is vertical. As the roller is lowered, a cam (not shown) on the cam shaft 41 lifts a push rod to cause the roller to perform its tilting action about an axis 84. The frame 33 may be adjusted along the axis 84 to allow the centre of the roller to engage the centre of the clay. Counterweights 85 (and 86, not shown) are provided to counterbalance the weight of the roller about the axes 34, 84, respectively. The drive 12, 14, 15 from the motor 11 to the spindle of the jigger head is interrupted, and the spindle braked, between shaping operations. The rim of the moulded article is trimmed by a tool 23 which is moved to engage the article by a cam 24a-operated push rod 24. The roller is cleaned between shaping operations by a wiper 90. A column of clay is fed to the machine by an intermittently driven endless conveyer. Each time the conveyer stops a wire cutter (see Fig. 1, not shown) is operated by the push rod, which causes the tilting movement of roller, to cut a piece from the column. The surface of the roller may be sprayed with oil, and the relative speeds of the jigger head and roller may be varied. The timing of the roller movements is adjusted by changing the cams. Specifications 621,712, 657,544 and 676,428 are referred to.

Filed: 1958-10-29
Abstract: 855,680. Packaging-machines. HESSER MASCHINENFABRIK A.G., F. Oct. 29, 1958 [Nov. 14, 1957], No. 34678/58. Class 94(1). Apparatus for evacuating and sealing packages comprises a series of pockets on an intermittently rotatable drum, the pockets being shut except when in filling and discharge positions, at which positions a package with one or more ends unsecured is fed into a pocket and an evacuated package is withdrawn with simultaneous sealing of its end seams. The apparatus described may replace air by inert gas.. Pockets 6 are pivoted on the drum 1 on shafts 5, the latter having arms 7 bearing followers running in a cam groove 9. The open ends of the pockets are closed by plates 12 mounted on the drum and spring biased against the pocket ends. Packages before and after treatment are carried in pockets of a conveyer F. The untreated packages P have the two end seams N, N<SP>1</SP> unsealed and notched on one side as at A. When each pocket approaches the discharge position it is pivoted clear of the respective plate 12, the plate having been raised clear of it by a fixed cam 15. When empty, it is retained open and, as shown, at right angles to the conveyer F, as it reaches the filling position. Here a ram 19 thrusts a package into it from the conveyer, clips 21 retaining the package as the ram withdraws. As the package entered the pocket, portions 28 on the ram opened pairs of fingers 23, 24 pivoted on opposite sides of the pocket. Withdrawal of the ram permits the fingers to close on the end seams, a nose 25 on each finger 23 engaging one wall of each seam through the notches A so as to open them (see Fig. 3). Continued movement of the drum causes the pocket to close and fixed cams 37, 37<SP>1</SP> to operate valves 35, 36 to evacuate air and supply inert gas to the pocket. At the discharge position, the pocket is again opened and heated jaws 30, operating in unison with the ram 19, enter the pockets to grip the end seams, holding apart the fingers 23, 24 in so doing. The seams are sealed as the package is drawn into the conveyer pocket.

Title: Manufacture of calcium borates
Inventor: NIES NELSON PERRY
IPC: C01B35/10
Filed: 1958-10-29
Abstract: Calcium metaborate is prepared by effecting reaction between borax, calcium hydroxide or oxide and one or more calcium salts in aqueous medium in the absence of added caustic alkali.  Calcium sulphate or chloride are the preferred calcium salts and they should be employed in slightly less than the stoichiometrically equivalent amount relative to the alkali metal oxide provided by the borax.  Calcium hydroxide should be employed in slight stoichiometric excess.  The reaction may be effected at 0-100 DEG  C. but temperatures of 10 DEG to 20 DEG  C. favour the production of hexahydrate, tetrahydrate being formed at higher temperatures. According to an example borax was added to a slurry of calcium hydroxide and sulphate, the mixture stirred and a minor amount of calcium metaborate hexahydrate was added as seed.  The calcium metaborate hexahydrate product was filtered off and had a CaO : B2O3 ratio of of 1.08 : 1.00. Specification 859,344 is referred to.

Abstract: 1364522 Carbonated beverage dispensing system DISTILLERS CO (CARBON DIOXIDE) Ltd 19 Oct 1972 [24 July 1971] 34845/71 Heading T [Also in Division F1] A carbonated beverage, e.g. beer, dispensing system has the beer pressurized by carbon dioxide in container 1, Fig.1 and is pumped at 5 when dispense valve 2 is opened to reduce downstream pressure, actuate pressure switch 8 and start the pump. On closing valve 2, check-valve 6 closes, the pressure builds up and opens the switch thus stopping the pump. If gas is present in lines 4, 7 or pump 5, pressure may not increase in line 7 on closing valve 2 and the pump may continue to speed. To prevent this, pressure switch 8 is in series with the pump motor 9 connected to the mains at 12, 13, and with switch 15 controlled by timer 14 in parallel with the motor. When valve 2 is opened, pressure switch 8 starts the timer which closes switch 15 and starts the pump. On closing valve 2, normally the pump and the timer stop, the latter resetting itself. However if gas is present and on closing valve 2 the pressure is not increased to stop the pump, the timer opens its switch 15 after a predetermined time to stop the pump. The timer may illuminate a sign and lock the valve 2 closed until the system receives attention. Two kegs 1 may be connected to the system and when gas is evolved due to emptying of one keg, the timer switches over to the other keg.
