Abstract: 1350538 Compression moulding WERNER & PFLEIDERER 29 Sept 1972 [19 Nov 1971] 45057/72 Heading B5A A press to compact powder or fibrous material has two vertical cylinders 1, 2 pivotally mounted in a frame 3-6 for movement between a filling station and a pressing station where a compacting piston 24 is introduced into a cylinder 2 and a suction device 27 is connected to evacuate the cylinder, each cylinder having a die 13, 14 slidably mounted therein and having a device, Fig. 2, by which the frictional engagement of the die with the cylinder walls is adjusted. Each die has rings 15, 151 engaging the cylinder walls and resilient sealing rings 16, 17. A clamping ring 18 is displaced upwardly by adjusting screws 19 to compress ring 17 and thereby displace ring 15<SP>1</SP> outwardly. A cylinder 1 receives a charge through a filling tube 32 which is slidably mounted on tube 33 and lowered by a ram 34 into cylinder 1, forcing the die 13 to the bottom of the cylinder. A filled cylinder 2 has been pivoted, by a rotary piston 10 engaging an extension 12 of the cylinder mounting 8, to a position beneath a piston 24 which is lowered into contact with the charge. A suction device is lowered by rams 24 and air is evacuated through passage 31 as the die 14 is raised by piston 21 to pre-compress the charge. Piston 21 is fixed by blocking its return flow and piston 24 is lowered to effect final compression. The compressed block is forced out of the cylinder 2 by piston 21 and is discharged by an arm 35 on to a conveyer (not shown). The die 14 remains at the top of cylinder 2 until depressed by tube 32.

A photographic silver halide material containing a tanning developer is developed, after exposure, in alkali and treated in a stop-bath comprising benzyl alcohol, an acid, water and if necessary to solubilize the benzyl alcohol in the water a mutual organic solvent for benzyl alcohol and water. The organic solvent may be triethylene glycol, ethyl alcohol or 2-ethoxyethanol. Acids specified are phosphoric, acetic, glycolic and citric acids. The tanning developer may be 4-phenyl-catechol and may be incorporated into the silver halide emulsion layer which may also contain paraffin wax. Alternatively, the developer may be coated in a layer between the support and the emulsion, which layer also may contain colloidal silver, and in which case the silver halide emulsion layer may be overcoated with a fogged silver chloride emulsion (see Specification 978, 744). The material becomes greasy-ink receptive in the exposed areas and may be used for printing in a duplicator, for example with Vanson ink and a fountain solution containing ammonium dihydrogen phosphate, ammonium nitrate, nickelous nitrate, formaldehyde diethylene glycol and water.

Filling containers.-Two flowable food products of different colours are filled in a spiral pattern into a container by relative rotation, during filling, of the container and a nozzle providing a composite stream for filling it. In the form illustrated spaced rotating supports 35 (Fig. 1) lift each container in turn from a conveyer and spin it as it is filled from a nozzle 23. The container is gradually lowered as it is filled, and a valve within the nozzle is helped to secure a sharp cut-off of material by raising the nozzle abruptly at the end of the feed. The nozzle is provided with a feed 95 of ice cream and a feed 96 of coloured syrup which forms a separate thread towards the outside of the icecream stream. A separate valve within the nozzle may control the feed of syrup. Several containers disposed side-by-side may be filled simultaneously. Applying lids; expelling air.-Lids 120 (Fig. 19) are withdrawn from a magazine 119 (Fig. 1) by a suction member 150 which rotates, as it is lowered to drop the lid on to the filled container. The container is then squeezed by fixed ramps at the sides of the conveyer or by inwardly moving plungers, to ensure the escape of air, and the lid is pressed into position by a member 165 so that portion 155 (Fig. 19) of the lid takes under a bead 154 on the container. An alternative container (Fig. 21, not shown) has a square-section bead at its other edge, and this takes into a corresponding groove in the skirt of the lid.

Title: Improvements in or relating to a Method and Apparatus for Stacking Glass in Sheet Form
IPC: B65G49/06
Filed: 1966-10-26
Abstract: 1,156,926. Sheet delivery; stacking; endless conveyers. PILKINGTON BROS. Ltd., R. BARRADELL-SMITH., J. E. HALL, and J. ROBY. 23 Oct., 1967 [26 Oct., 1966], No. 48075/66. Headings B8A and B8R. Glass sheets are stacked by a process which involves lifting the sheets from a conveyer into contact with a movable suction belt, retaining the sheets in contact with the belt during movement towards a stacking station, mechanically prising the leading edge of each sheet in turn from the belt to allow the sheet to drop on to a stack, and positively stopping the advance of each sheet after prising from the belt to accurately align the sheet with the stack. General arrangement (Fig. 2).- Sheets 1 carried on a conveyer 2 from a cutting machine are brought into contact with the lower run 9 (Fig. 3) of a perforated belt 8 by means of suction applied through inlets 54; the belt 8 carries the sheets to a position above a stacking station where further suction inlets 58 are provided, suction to these inlets being removed when the leading edge of a sheet 1 intercepts an air blast from nozzle 63, the increase in back pressure controlling the suction. The sheets are mechanically prised away from the belt 8 by a rotarv device 64 projecting through the lower run 9, and the sheets drop on to a stack which builds up on parallel beams 70 (Fig. 3) carrying cushioning strips 71. Cushioning of dropping sheets is assisted by blast from gas nozzle 75 and the blowing of particulate material, e.g. wood flour, from blower 82. Conveying.-The endless belt 8 is provided with perforations 50, an imperforate central strip 51 and imperforate edges 52. Suction is provided to the lower run of the belt by means of duct 56 the imperforate edges 52 having suction applied thereto through auxiliary ducts 62 to help support the belt. Drive to the belt is supplied through rollers (12), 27 (Fig. 1, not shown) and tension is maintained by roller 47. The conveyer 2 which is mounted in bearings 3 on beams 4 may run in the same direction as belt 8 (Fig. 5, not shown). Table actuation and sheet alignment (Fig. 3).- A sheet prised away from the underneath of the belt still continues to move forward until it contacts pivoted bumper bar 72 which tilts against the action of spring 74 to actuate switch 76; this switch controls motor 77 to cause table 70 to drop by one sheet thickness at a time. When the table is lowered sufficiently, roller conveyer 83 removes the completed stack. The bar 72 aids alignment of the sheets, further aids including the blast from gas nozzle 75, pneumatic rams (not shown), and tilting the belt and the table. Similar retainers &c. can be used for transverse alignment (Fig. 5, not shown), and detecting devices for different sizes of sheets can direct them into alternative receivers (Fig. 4, not shown).

The linearity of the system, which may be used in a vibration tester, is thus improved and its damping factor is less dependent on signal amplitude. The valve 13 is a spool valve operated by a torque motor while the actuator is a doubleacting ram. An accelerometer 16 feeds back signals through a proportional gain controller 20 and through a signal processor 17, a multiplier 18 and a phase shifter 19, this latter signal being modified in consequence of spool displacement or through a second phase shifter 21 responsive to the error signal in the amplifier. In a further embodiment, a fourth feedback loop consisting of a pressure sensor (24), Fig. 8 (not shown), an invertor (25) and a SPDT switch (27) operated through a sign discriminator (29) is provided, the signal from the switch and from a supply pressure setting device (30) being combined in an adder (26) connected to the forward path through a square-root circuit (31), a signal processor (32) and a divider (23).
