Title: Apparatus for transferring gripping fingers of a plate changing device
Inventor: SARTORIO FRANCO
IPC: B23Q3/155
Filed: 1990-11-13
Abstract: The apparatus comprises a body (22) having a handle (23). A pair of gripper members (24) are slideably mounted on either side of the body (22) for movement toward and away from the body (22) and are urged toward the body by means of springs (25). A movement mechanism (28) comprises a pair of links (40a, 40b) and a rod (38) is housed in the body. The links (40a, 40b) are each pivotally connected by one end to a respective gripper member (24) and by the other end to the lower end of the rod (38). The rod (38) is vertically slideable within the body (22) so that, when the rod (38) is pushed downwards, the links (40a, 40b) lock in a horizontally aligned position, moving the gripper members (24) away from the body (22). Release of the rod (38) causes the springs (25) to move the gripper members (24) back toward the body (22) and so grip a machine part positioned between the gripper members (24). The rod (38) can be held against the body (22) to retain the links aligned and is releasable by a sliding device (29). The gripper members (24) have pins (60) for locating in gripping fingers of the plate changing device for a bending press. <IMAGE>
Patent GB-906543-A (GB)
IPC: C07D295/027
Abstract: 906,543. Injection moulding. PIOTROWSKI, T. Sept. 30, 1958 [Oct. 12, 1957], No. 31163/58. Class 87(2). In the blow moulding of plastic articles by injecting on to a core to form a pre-shaped blank which is subsequently expanded, the core is apertured, for the emission of gas in blowing, finely enough to prevent entry of the injected plastic and within only a narrow zone of the core surface, this zone being located close to the neck of an expansion mould during blowing. A fluid e.g. oil is supplied to the core interior at a temperature between 100C and 250C and at a rate sufficient to maintain the core exterior at a uniform temperature. In Fig. 2 oil is supplied through a duct 18 to a space 19 within a core cap 12 and is discharged through ducts 20. Air for blow moulding is supplied through a duct 17 to an annular duct 16 and escapes through an annular gap 26 between the cap 12 and base 14. Cooling fluid can be circulated through an annular duct 23 to solidify the neck portion of the moulded article. In Fig. 3 plastic material is injected through a nozzle 6a into an injection chamber 4 defined by a core 2 and a mould portion 6. The core 2 and a second core 3 are carried by a part 1 which is rotatable to bring the core 2 into an expansion chamber 5 and move the core 3 into the injection chamber 4. Temperature stabilizing fluid is supplied to the core interiors through a duct 7. Air for blow moulding is supplied through ducts 11. Before blow moulding takes place a piston head 30 may be advanced to contact the plastic material e 1  under light pressure. This causes localised cooling, hardening and strengthening of the plastic material. The piston head 30 may incorporate an embossed design and is withdrawable flush with the surface of the chamber 5 as shown. Alternatively, the core or mould may be so shaped that the plastic material will be in contact with the opposite face of the mould before expansion takes place. Fig 6 shows a further embodiment wherein injection takes place with a piston 42 in the position shown, and blow moulding with the piston withdrawn to a position in which the piston head 43 fits into a recess 48 at the base of the expansion chamber 40. Plastic material is injected through a nozzle 47 into a chamber 46 defined by a mould cover 39 and a recess in the piston head. Temperature stabilizing fluid is supplied through ducts 49, 51 and air for blow moulding through ducts 52. Cooling ducts 54 may be provided in the cover 39.

Title: Tongue cleaning instrument
Inventor: PATEL RITA PRANJIVAN
IPC: A61B17/24
Filed: 1991-10-22
Abstract: A tongue scraping and massage instrument for freeing and removing pathogenic foreign matter, bacteria and dead cells that remain and are entrapped on the upper surface of the tongue consists of a pair of elongated handles (2) which are connected specifically by a U-shaped bar (3) which forms the scraping edge (8). The scraping bar conforms to a general triangular shape in cross-section becoming rectangular on the inner aspect of the upper surface where an extended flange (5) is incorporated for collection of debris. There are no sharp corners or abutments in this device as it is a continuous U-shaped instrument and so the handles and scraping bar are sufficiently rigid to resist torsional flexing of the handles and minimize the tendency of the scraping edge to partially disengage the tongue. The U-shaped scraping edge conforms to the shape of the tongue hence covering a large surface area. <IMAGE>

Title: Moving bed coal gasifier
Inventor: HALOW JOHN STEPHEN
IPC: C10J3/26
Filed: 1992-08-25
Abstract: A moving bed coal gasifier 10 for the production of tar-free, low ammonia fuel gas, employs a combustion zone 20 in a free-board area above the moving bed 24 to burn coal fines to provided hot combustion gases for pyrolyzing and gasifying coal particulates in the moving bed to form fuel gas as the hot gases move co-currently with the downwardly moving coal particulates. The fuel gas contains entrained tars and ammonia compounds which contact hot char and ash in the moving bed and are cracked so that the fuel gas removed from the gasifier at a mid-point off-take 40 is essentially tar-free and of low ammonia content. Concurrently with this gasification reaction, steam and an oxidant are introduced into a region below the moving bed to flow countercurrently to the downwardly moving bed to contact and react with carbon remaining in the char to create additional fuel gas which is, also extracted from the gasifier at the mid-point off-take 40. <IMAGE>
