Title: Softening PVC tube prior to socket forming - by radiant heat in oven whilst preventing excessive exposure of extreme tube end by baffle
IPC: B29B13/02
Filed: 1979-11-20
Abstract: The arrangement is intended for heating the end portion of a thermoplastic tube (6) by radiant heat (4,11) so that it can be formed, e.g. to produce a socket end. The extreme end of the tube is protected (5,10) from excessive radiation to prevent decomposition or charring of the tube material. The protection may consist of a metal baffle disc (5) which may be provided with a flanged rim (10). The baffle may be in the form of a truncated cone which diverges away from the extreme tube end. The tube may be in a poly-alkene material or preferably PVC. Softening by radiant heat permits rapid treatment with tube in horizontal position as opposed to using immersion in heated liq. This arrangement prevents excessive heating with attendant undesirable effects on tube material.

Title: Method and apparatus for degasing during transportation a confined volume of liquid to be measured
Inventor: LEIJ JAN DOEKE BIJ DE
IPC: B01D/
Filed: 1980-01-29
Abstract: A confined vol. of liq. is degassed during transportation from a supply vessel to a liq. storage vessel. Liq. is withdrawn from the supply vessel and passed to a gas sepn. vessel for passage via a volumeter to the storage vessel. The supply and discharge of the liq. to, and from, the gas sepn. vessel is dependent upon subatmospheric pressure maintained in the vessel. Switches are provided in the gas sepn. vessel which are responsive to the level of the liq. for actuation of valves for supply and discharge of liq. Used in milk collecting system.

Title: Apparatus for orientated feed of ferromagnetic components
Inventor: ZUBOV EVALD KONSTANTINOVICH
IPC: H01F/
Filed: 1981-03-13
Abstract: Ferromagnetic component orienting mechanism, used in production for orienting, faulty component ejection, sorting, assembly and loading, has improved reliability and productivity. This is achieved by the open rectangular shaped electromagnet being horizontal and having an additional coil determining the oriented position. The coil connects through an amplifier to the electromagnet feed unit. The component feed chute in the zone between the electromagnet poles has a ramp and the spring-loaded platform is of ferromagnetic material and offset from the orientation zone towards the direction of flow of components. The flat ferromagnetic components are fed by vibrating chute (1) to orienting zone. The alternating magnetic field vibrates platform (3) and the nearest component A is attracted, repelling the component B. The component briefly breaks contact with the electromagnet and its longer side then closes the poles. As component rotation occurs its diagonal passes through a position parallel to chute (1) axis at which point component A and the front end is raised to close the poles of electromagnet (2). Additional coil (4) voltage rises rapidly and the signal is used to de-energise the electromagnet. The component fails from ramp (7) onto the main chute level and passes on, component V having already been advanced. Bul.41/7.11.80.

Title: System for dispensing curable compositions
IPC: B29B7/00
Filed: 1982-03-03
Abstract: A method and apparatus for dispensing curable compositions formed by a mixture of first and second materials which, when mixed in prescribed ratio, interact with each other to provide a relatively rapidly curable composition, such as a polymerizable epoxy resin or the like. The materials are individually pumped and metered through a first mixer (36) and a dispensing valve (40) to a dispensing nozzle (44). During start-up, the dispensing valve (40) is closed, and the initial mixed composition is diverted through a bypass valve (48) for dilution and mixture with a diluent stream of the first material in a second mixer (60) and for return of the diluted mixture to the supply reservoir (18) of the first material. When a homogeneous mixture of prescribed ratio is achieved at the outlet (38) of the first mixer (36), the bypass valve (48) is closed and the dispensing valve (40) can be opened to allow dispensing of the composition. Upon shut-down, supply of the second material to the first mixer (38) is ceased, and the dispensing valve (40) and bypass valve (48) are closed and opened, respectively. The first material is supplied to the first mixer (38) and through the bypass valve (48) to flush the composition therefrom and for dilution of the composition with the diluent stream in the second mixer (60).

Title: Process for the preparation of a protected pigment
IPC: C09C/
Filed: 1983-02-24
Abstract: A protected pigment is made by including a pigment in transparent Zr silicate crystals by (a) simultaneously or sequentially precipitating the constituents of the protected pigments from an aq. or nonaqueous soln. of their salts; and pref. (b) mixing the resulting ppte. with a fluoride, heating the mixt. to high temp., and cleaning the produced protected pigment. The constituents of the protected pigment are pref. (i) a pigment or its precursor; (ii) Zr hydroxide or hydrated ZrO2; and (iii) silicic acid or hydrated SiO2.
