Title: Heat exchange appts. for slurries or pulps - using two sets of tubes embedded in solid metal
Inventor: GOULOUNES NOEL
IPC: F28D7/00
Filed: 1975-08-20
Abstract: The appts. is for heat exchange between two flows of granular powdered or coloidal material suspended in liqs. in the form of pulp. One of the flows is effected inside tubes arranged parallel in a bundle terminating of transverse tube plates, surrounded by a shell. The second flow passes through a second series of tubes parallel to the first series, alternating regularly with them, and the space between the tubes and the shell is filled with a metal or alloy (esp. Al) in the solid state. The appts. is esp. used for treating a pulp of calcium sulphate dihydrate at 120 degrees C so that it is transformed into a pulp of calcium sulphate hemihydrate. No dead flow zones occur in tubes as when one set of tubs is enclosed in the outer cylinder through which the second liquid is flowed. Hence pulp and slurries can be used for heat exchange without blockages.

Title: Automatic leakage testing of plastics bottle tops - uses vacuum generated by straightening of squashed plastics bulb to retain top
IPC: G01M3/34
Filed: 1976-01-05
Abstract: Low cost of plastics containers requires automatic checking for stopper leakage and automatic sorting. This is performed by crushing a plastics bulb creating an internal vacuum. Leakage causes the bulb to expand to release the faulty stopper or top. Bottle tops (2) are stored in a vibrating container (4) and travel down a ramp (R6). Plastic bulbs (6) are squashed by a finger (8) on a roller (12) shaft (10) following a ramp (Ra). The open end (16) of each bulb locates with a bottle top (14) on a ramp (Rc) while being squashed. Roller ramp (Ra) shape ensures release of the finger (20). Leaking tops (22) permit respective bulbs (24) to reflate allowing faulty tops to fall into a container (Cb). Satisfactory tops are released into another container (Ca).

Title: Tip and sleeve valve for screw of injection moulding machine - with an eccentric head to let the sleeve be removed over the tip
IPC: B29C45/52
Filed: 1976-02-25
Abstract: An extruder screw tip with an eccentric head and bevelled faces at each end of an integral neck for locating against a sleeve valve which is slightly shorter than the neck. Used esp. for injection moulding machines where reciprocation of the screw is used to fill the mould. The sleeve may be removed over the head of the tip by an axial shift when the screw is advanced sufficiently clear of the barrel, without needing to extract the screw completely and remove the sleeve over the screw root, yet the sleeve is captive when the head is in the barrel. Sleeves and/or heads can therefore be readily substd. to suit different melt characteristics or shot sizes. The melt has a clear peth past the shallow sides of the head, is less prone to blocking or delayed remelting than designs where the melt passes the head through drilled passages or surface channels. The tip is more robust than designs involving separate root, neck and head components coupled (screwed) together.
