Title: Injection moulding
IPC: B29C45/00
Filed: 1974-04-01
Abstract: 1510300 Injection moulding; locating inserts IMPERIAL CHEMICAL INDUSTRIES Ltd 1 July 1975 [1 April 1974 18 March 1975] 14282/74 and 11185/75 Heading B5A An injection moulded plastics article containing an encapsulated rigid insert 4 is made by placing the insert against the mould face of a first mould member 2, injecting plastics material through an opposed mould face in a second mould member 1, and effecting relative movement between the insert 4 and the first mould face while maintaining the insert supported by spaced pins 5 passing through the first mould member 2 so that the plastics material flows into the space so formed between the insert and the first mould face thereby encapsulating the insert. The movement between the insert and the mould face is produced by moving either the first mould member 2 (Figs. 1, 2) or the pins 5 (Figs. 6 and 7), or both (not shown). Non-foaming plastics material may be used but preferably it is foamable so that it will fill the space occupied by the pins 5 when they are withdrawn. The foamable material may be sandwiched between non-foam layers in the manner disclosed in Specification 1,156,217. The injection pressure may be high enough to prevent foaming during injection, the foam expanding only when the mould cavity is enlarged by movement of the first mould member 2 or by an insert 4 which contains a cavity 13 (Fig. 6). Wooden or hollow or T-section metal inserts may be encapsulated in polyurethane, P.V.C., or polypropylene to form window frames, furniture or car bumpers. Two of the pins 5 may be attached to the insert in a bumper to form means of attachment to a vehicle.

Filed: 1965-04-05
Abstract: 1,072,318. Making rod; rolling; casting machines. SOUTHWIRE CO. April 5, 1965 [Nov. 12, 1964], No. 14284/65. Headings B3A, B3F and B3M. Metal rod supplied continuously from a casting wheel is passed through a temperature regulating furnace and a rolling mill entirely in a protective atmosphere to prevent oxidation of the rod. The rod passes through a duct (24a) (Fig. 1C, not shown) from a grooved casting wheel (22), and into an insulated chamber (10) into which a non-oxidizing gas is introduced through a pipe (44). Immediately following the chamber (10) is a furnace (11) (Fig. 1B, not shown) including a gas burner (52) and scarfers (131) for removing flash from the metal edges. The temperature of the metal in the furnace is automatically kept constant under the control of thermocouples at the entrance of the furnace. The rate of combustion of gas in the burner is controlled and also the flow rate and temperature of cooling gas introduced through an inlet (59). The combustion in the burner is incomplete to leave a reducing atmosphere in the furnace. The heated rod passes to a continuous rolling mill 12 supplied with coolant nozzles 92 and reducing gas inlet nozzles 95, the rod then passing through a tube in which it is cooled by a fluid forced along the tube and subsequently cleaned of fluid using air jets. Instead of passing through a totally enclosed mill 12, the rod may pass between the stands, through guide tubes, coolant being sprayed on the rod to prevent the access of an oxidizing atmosphere.

Title: Improved automatic bag filling and weighing machine
IPC: G01G13/00
Filed: 1939-07-16
Abstract: 533,634. Weighing - apparatus. TALBOT, G. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 16, 1939, No. 14634. [Class 143] In a bag-filling and weighing machine wherein the bag is supported on a scale pan carried by a frame and is filled from a spout, the bottom of the scale pan can be collapsed when the correct weight is reached, to permit the bag to fall freely from the frame. As shown, the scale pan comprises a back 35 and two bottom flaps hinged on pins 33. The flaps are retained in the closed position shown, by stops 7 which bear on the lower surfaces of the frame 6, the frame 6 being carried by the balance beam 9. The scale pan is mounted in the frame 6 on pivots 14. When the bag reaches the correct weight the frame 6 descends and releases a trigger mechanism 26 thereby closing the feed slide 4 and cutting off the feed through the spout 2. At the same time a lever 17 falls on to a lever 31 and releases a bag clamp 3. The weight of the unclamped bag tends to tilt the pan about its pivot 14 but this is prevented by a lever 15 and stop 16 until the stop is released by the pressure of a knob 22, this knob being operated by mechanism 21, 19 actuated by the upward movement of the starting lever (similar to the lever 17) of an adjacent bag-weighing mechanism. The filled bag then tilts about the pivot 14 and moves off the spout 2 as shown by broken lines. The stop 7 at the same time moves to a cut away portion 32 and permits the flaps 5 to open and drop the filled bag into a shoot 23. The scale pan is returned to its original position by a spring or a counter-balance weight or by the operator. The collapsing, or tilting and collapsing, of the scale pan may be effected by electrical, pneumatic or other means. The shoot 23 has an upward extension 25 to protect the operator from dust.

Abstract: 911,363. Testing brakes. DUNLOP RUBBER CO. Ltd. May 4, 1959 [May 8, 1958], No. 14709/58. Class 103 (1). [Also in Groups XXIX and XL (b)] Apparatus for regulating the pressure supplied to a fluid pressure-operated mechanism, e.g. a brake, in accordance with test requirements in the form of a curve plotted between two variables, eg. speed and braking torque, includes an oscilloscope 18 having on its screen a mask 22 having an edge shaped in conformity with the test curve. The beam of the oscilloscope is moved in response to the two variables and if it moves clear of the mask, a light-sensitive cell 24 operates to effect control of the fluid pressure supplied to the mechanism. In Fig. 2, a wheel 10 fitted with a brake is driven by an inertia wheel 11 which also drives a D.C. tacho-generator 21 which supplies the oscilloscopes 17, 18 with a signal representative of the speed. An arm 12 bears against a pressure capsule 13 which provides a signal representative of the torque. The oscilloscope 17 gives a visual indication of whether the brake is conforming to the test. The signal from the light-sensitive cell 24 is fed through an amplifier 25 to a solenoid 35 which adjusts a tube 32 emitting a stream of fluid towards an outlet 30 and the resultant pressure is conveyed through outlet 30 to adjust the brake. The solenoid may be coaxial with the tube and be associated with a cam contacting a cam surface in the end of the tube. In a further modification, the amplifier 25 actuates a splitfield motor connected to the tube 32 through a reduction gearing.

Title: Improvements in or relating to high speed textile winding machines
Inventor: BRIERLEY EDGAR
IPC: B65H59/38
Filed: 1955-05-23
Abstract: 849,971. Automatic stop mechanism. LEESONA HOLT Ltd., [formerly TWO GATES MILL Ltd.]. Aug. 23, 1956 [May 23, 1955], No. 14763/55. Class 120(2). A high speed textile winding machine of the type in which the package being wound is driven by surface contact with a driving roller is provided with hank entanglement stop motion mechanism which reduces the risk of breakage of the yarn by ensuring that when an entanglement of yarn occurs a brake is put into action to lift the package clear of the driving roller and stop the turning movement of the winding package; in which the tension in the yarn between the swift and the yarn package may be adjusted to prevent undue tension thereon; and in which when the entanglement has been cleared the mechanism acts to release the brake and to lower the yarn package on to the driving roller to recommence winding. In the embodiment shown yarn Y travels from a swift 11 over a guide pulley 32 then around a guide pulley 30 at the end of an arm 19, round a further pulley 33 and after passing through tensioning means and a slub-catcher is wound on to a package resting on the driving drum 12. Should entanglement occur at the swift 11 the sudden increase in tension pulls the pulley 30 and arm 19 downwards against the action of a spring to the chain-dotted position shown. Movement of the arm 19 rotates a cam surface 25 which is in contact with a follower at the end of rod 22 such that the latter is depressed and rotates a bell-crank lever connected to its opposite end. Movement of the bell-crank lever draws a brake-shoe between the driving roller 13 and the package 15 and stops rotation of the latter. When the entanglement has been cleared the arm 19 returns to its original position under the action of its spring and through the reverse sequence removes the brake shoe from between the driving drum and the package. Movement of the brake shoe may also be used to move a yarn lifter for lifting the yarn free of the traverse guide.
