Title: Improvements in or relating to platen-presses
IPC: F16H35/10
Filed: 1962-10-30
Abstract: 955,055. Safety devices in platen presses. J. BOBST & FILS S.A. Oct. 30, 1962 [Nov. 14, 1961], No. 41090/62. Heading B5F. In a platen-press comprising a movable platen driven by a toggle mechanism operated by a worm screw as a safety device against over pressures is the worm screw is axially movable against means for holding it back with a thrust at least equal to that resulting from the normal driving of the press, but such that axial displacement of the screw takes place when the said thrust exceeds a predetermined amount. The driving end of the screw shaft 10 (Fig. 2a) has a lengthwise grooved head 16 co-operating with a driven sleeve 17 similarly grooved internally. The opposite end of shaft 10 is rotatably mounted in an outer cylinder 20 by a bearing 18 and thrust race 19 in such manner that the cylinder can move axially with the shaft 10 in a frame 21. The cylinder 20 is continued by a truncated conical sleeve 22 the free end of which is connected to a rectangular shaped rod 23 (Fig. 2b) which in turn is connected through an aperture in one plate 25 of the box containing the safety device to a similar rod 24 of slightly larger dimensions. The free end of rod 24 pushes against shoulders 26 of half jaws 27 pivotable at joints 28 to which are attached connecting rods 29 pivoted about fixed axes 30. The joints 28 have notches into which rest rods 32, being retained in this position through the action of powerful washers 33. When the pressure exerted by screw 8 exceeds a predetermined amount the shaft 10 moves axially out of sleeve 17 and so pushes the cylinder and sleeve assembly 20, 22 and rods 23, 24, which in turn move half jaws 27 against the action of rods 32, until a projection 39 on rod 24 contacts a spring loaded stop 37. At this point, in order to prevent any reverse motion, grips 41, pivotal about fixed axes 42, are caused to engage with corresponding notches 43 in the rod 24 (Fig. 3). In an alternative embodiment a rectangular rod 44, Fig. 5, has a notch 46 at its free end which on axial movement of shaft 10 engages with a tooth 48 of lever 47 acting against a spring loaded rod 50.

Abstract: 1403624 Dispensing liquids AKZO NV 5 Sept 1972 [6 Sept 1971 (2)] 41148/72 Heading G1W [ Also in Division F2] A device for dispensing a predetermined weight of a liquid from a reservoir 5 into a can 12 comprises a dispensing device 10 which allows the liquid to run into the can at diminishing flow rates in successive stages under the control of weighing device 1, the weighing device 1 causing the flow of liquid to be cut off completely when the predetermined weight is reached, the total weight the can should have after dispensation of the predetermined weight of liquid being set on the weighing device by riders 23, 24, 25 moving on guides 20, 21, 22. A variety of liquids are contained in reservoirs 5 mounted on a turret 4, and the correct reservoir 5 is brought automatically into position over can 12 when the operator presses the appropriate button on control 27. As the turret 4 rotates, a stirrer in each reservoir is rotated by means of a pinion 9 meshing with a gear wheel 6. The operator then adjusts the positions of the three riders 23, 24 and 25 along beams 20, 21 and 22 to set the hundreds, tens and units respectively of the weight. The dispensing device is controlled by means of a lever 13 actuated by a sliding rod 14, which is controlled electromagnetically by the control 27 and the weighing device 1. To dispense the liquid, a button on control 27 is pressed, and liquid is fed into can 12 at a high rate. When a first predetermined weight is still to be dispensed, the balance provides a first signal, and the liquid is then dispensed at a medium rate. When a second predetermined weight is still to be dispensed, the balance provides a second signal, and the liquid is then dispensed at a low rate. When the desired weight is reached, a third signal provided by the balance cuts off the liquid feed. The signals may be provided from the balance by photo-electric means or magnetic means. The device may be used to dispense successively into a can 12 the ingredients required to form a can full of paint. To aid setting of the riders 23, 24, 25 for the successive liquids, a chart may be provided showing the rider positions Fig.9 (not shown). Each beam 20-22 has a distinctive appearance by virtue of colour, hatching, cross-sectional shape or imprint, and the corresponding section of the chart has a corresponding appearance. Fig.2 shows a form of the dispensing device. Valve member 39 is slidable in cylinder 37 and is coupled to the cylinder 37 by a pin 46 engaging slots in the cylinder 37 Figs.5, 6 (not shown). When lever 13 is operated, member 39 is raised and slides relative to cylinder 37 by virtue of the pin 46 sliding in the slots to open the smaller valve opening 40. If the lever 13 is moved further, the pin 46 engages the ends of the slots and lifts cylinder 37 and the associated valve member 31 to also open the valve opening provided by the mouth of sleeve 30. The first two flow rates are provided by different openings of the outer valve.

A conveyer has a wheeled carrier 10 having a bolt 12, Fig. 1, projecting through a channel in floor 11 to be engaged by a dog 14 of a driven chain 15, a second bolt 13 extending into the channel clear of dogs 14 to prevent angular movement of the carrier about bolt 12. To reverse the direction of movement of the carrier without substantially moving the carrier angularly, the bolt 13 passes a switch 21, Fig. 2, into channel 18<SP>1</SP> and engages lever 23 to rotate switch 21 so that bolt 12 passes into channel 17 still driven by chain 15 which is guided by rollers 16. Bolt 12 engages lever 24 to move switch 21 back to its shown position, an overcentre spring 22 biases the switch to its end positions. The bolt 13 then passes a spring- biased switch 25 into channel 20 and is then pulled along channel 19<SP>1</SP> as the bolt 12 is pulled from channel 17 into channel 19, bolt 12 being now at the front. At the opposite end of the conveyer to again reverse the carrier's direction of movement, bolt 12 passes switch 33, Fig. 3, into channel 27 and reverses switch 33 through lever 35, whereby bolt 13 enters channel 28, the bolt 13 moving switch 33 back to its shown position through lever 36. As bolt 12 is driven around channel 27 by chain 15, the bolt 13 passes spring-loaded switch 31 into channel 30 and then is moved along channel 29 back into channel 18 where it again leads bolt 12 as the carrier moves along parallel to channel 18. When a train of carriers are being moved a ramp 37 raises the driving bolt 12<SP>1</SP> of the preceding truck, Fig. 1.

Abstract: 1,256,372. Automatic alarm systems. PLESSEY CO. Ltd. 26 June, 1970 [25 Aug., 1969], No. 42163/69. Heading G4N. [Also in Division G1] In an arrangement for developing alarms according to the position of an indicating or recording stylus of a measuring device by vanes carried by the stylus interrupting either of the paths of two light source/photo-cell arrangements located in the plane of stylus movement when the stylus is deflected beyond predetermined limits, the alarm signals developed are different for the two positions and an additional differing signal is developed when the measuring device and alarm generating apparatus are functioning correctly. The apparatus is described in respect of a flame type methane detector and atone generator is included its output being continuous for a methane excess, and interrupted respectively at two different rates to indicate methane tester flame failure, or satisfactory operation of the equipment. The last named signal is a periodic burst of tone at every 12 seconds and is controlled by a timer circuit which renders the photo-cells which are photo-transistors non-conductive for the period. The tone generator output is keyed by a multivibrator when the light path of the lower limit detector is interrupted. Manual reset keys, and strapping points for fault simulation are also provided.

[Also in Division C3] Composite sheet material comprising a sheet of a thermoplastic synthetic polymeric plastics surface working material formed directly on and in adherence with the surface of a permanent support which consists of a fibrous material impregnated with an elastomeric synthetic plastics base working material, which is a polymer that is soluble in the common solvents for the surface working material, is prepared by forming a homogeneous mixture comprising a solid particulate removable filter and the surface working material by homogeneously dispersing the filter in the working material when the latter is in a plastic or liquid state and then removing any solvent used by evaporation, melt coating the homogeneous mixture as a continuous sheet on the permanent support by means of a melt roll coating machine which has a pair of horizontally disposed coacting rolls rotating in different directions at different peripheral speeds, the mixture being supplied to the nip of this pair of rolls, the rolls being heated to temperatures such as to render the surface working material plastic and the temperature and the difference in speed of rotation being such as to cause the mixture to form a continuous homogeneous sheet on the surface of the faster one of the rolls (the transfer roll), the sheet being transferred to the permanent support which passes between the transfer roll and a support roll which bears against the transfer roll and rotates in the opposite direction to the transfer roll, and exposing the sheet to a leaching agent so as to remove the filler but not to adversely affect the surface working material, the nature of the filler, the weight ratio of filler to surface working material and the conditions during the melt coating being selected to ensure that a continuous sheet of the mixture is formed and that the structure of the sheet is such as to enable the filler to be removed to form a porous sheet of surface working material. The permanent support may be formed by impregnating with the base working material a felt formed by mechanically entangling a web of staple fibres, the amount of impregnant used being such that the base zone remains appreciably vapour-permeable. Polyvinyl chloride and polyurethanes are preferably used as the surface working material and suitable fillers are water-soluble inorganic salts, such as sodium chloride. The resulting sheet material may be used in the footwear, clothing and upholstery fields.
