Title: Multicavity plastic injection mould with limited closure force - has injection into successive cavity groups thus increasing capacity
IPC: B29C45/12
Filed: 1980-10-07
Abstract: The arrangement is intended for injection-moulding plastic products by an injection head containing a screw spindle to inject heated plastic under high pressure into cavities in a mould (34) whose components are held in the closed position by a given closing pressure during injection. The mould contains two or more groups of cavities which are filled in succession. The mould is opened and the products are removed after all cavity groups have been filled and have cooled down. The plastic material in the injector may be replenished at the start of the cooling phase of one cavity group before commencing injection into the next group. Used for injection-moulding plastic products into multi-cavity mould. The arrangement considerably reduces the moulding time per plastic product by increasing the number of cavities per mould which would otherwise not be possible as this number is limited by the available mould closure pressure. This pressure would be insufficient for simultaneous injection into all cavity groups.

The liquid layer consists mainly of water which has a quaternary phosphonium compound added to prevent growth of bacteria as well as diethylhydroxylamine and a filming amine to prevent corrosion in that part of the inside of the cargo tank (2) which is adjacent to the layer (7).
Patent NL-9200029-A (NL)
Title: Method and apparatus for separating substances from a gas mixture
IPC: B01D53/00
Filed: 1992-01-09
Abstract: The present invention relates to a method for separating substances from a gas mixture, wherein a portion of the substances is condensed from the mixture and a further portion of the substances is filtered, characterized in that at least two filters are active alternately as separators, of which that filter which is not active as a separator returns to the condenser the substances it has separated off.

Patent NL-9301212-A (NL)
Title: Reversing valve
IPC: A62B9/02
Filed: 1993-07-12
Abstract: Reversing valve, intended to be used in a compressed-air or artificial respiration mask, comprising a valve housing with a valve body which can be displaced therein. The reversing valve is connected to a remote principal source and to a reserve source for compressed air and to the artificial respiration mask. The reversing valve has a first position, in which air flows from the principal source to the mask, and a second position, in which air flows from the reserve source to the mask. The valve automatically switches from the first position to the second position when the principal pressure source, for whatever reason, falls below a predetermined level. This change of position must take place quickly, without the valve body having the opportunity to adopt an intermediate position. For this purpose, the valve is provided with retention means which are able to hold the valve body in the first position or the second position, which retention means only allow the valve body to move from one position to the other if the resultant of the forces exerted on the valve body is greater than a predetermined threshold. These retention means comprise a ball which is under pressure from a spring and can engage in two recesses which are arranged at a distance from one another in the valve body. To provide additional security, a bypass is arranged in the valve housing, which bypass connects the connection port for the principal source to the connection port for the respiration mask, the said bypass containing a non-return valve which allows air to flow from the principal source to the artificial respiration mask but blocks the flow of air in the opposite direction.

Title: Cartridge/carrier locking device for automatic gun
IPC: F41C3/00
Filed: 1978-09-21
Abstract: The mechanism locks the cartridge and loading device of a machine-gun, having a breech block returning forwards to the initial position after recoiling on firing. A cartridge lock releases temporarily to allow the next one to be discharged from the magazine as the block moves rearwards, and the loading device is prevented from functioning until the cartridge has completely left the magazine. A locking plate pivots on the breech wall so that its ends protrude alternately inside the breech, the forward end holding a cartridge and the rear the loading device, a spring thrusting the rear end towards the inside of the breech. In opposition to the spring, the breech block and the next extracted cartridge limit the amount of protrusion of the plate rear end, until the breech block moves rearwards nearly to the end of its stroke.
