Title: Toner powder developer for photocopier - having magnet to control carrier and toner mixt. and meniscus to control rate of application
IPC: G03G15/09
Filed: 1974-03-27
Abstract: The toner powder and its magnetic base are throughly mixed in the bottom of the toner reservoir by stirrers. A rotating pick-up roller picks up a supply of toner mixture and passes it to the copy material held against the roller by two smaller rollers. The edge of the reservoir forms a lip near the top part of the roller and enables a toner meniscus to be set up, with excess toner dropping over the edge to another reservoir. The provides an automatic top-up system. A magnet held on the outside of the reservoir at a point, where the toner mixture passes between the roller and the reservoir wall, has the effect of removing excess magnetic base and providing a constant mixture control. Residual toner drops off the roller and is mixed in a worm stirrer before being passed back to the reservoir.

Title: Catering coffee-making machine - has time and pressure-sensitive changeover switches regulating water supply and heater
IPC: A47J31/54
Filed: 1974-06-24
Abstract: A metering tank is connected via a solenoid valve to the water mains, and delivers a calibrated quantity of water to a heater, which supplies it via a standpipe and dribbler arm to a filter containing coffee powder. A detachable collector pot is mounted below the filter for the coffee made. The control unit regulating the hot water quantity supplied to the filter has a time switch which, on being energised, holds the valve ready for a preset period. A pressure-sensitive changeover switch is fitted in the connecting pipe and opens the valve or switches on the heater depending on the water level in the tank. The two switches work together so that the valve can only be opened during the period when it is set ready.

Title: Boxless mould press with casting and cooling conveyor - has air cushion and opt. belt easing stepwise motion
IPC: B22C11/08
Filed: 1976-12-17
Abstract: An installation for making boxless moulds which consist of a series of identical mould sections of sand or similar material, placed accurately against each other, includes a modelling chamber. In this the mould sections are produced by pressing the sand between two opposing model plates. A stringing section is adjacent to the pressing zone, and in this, the mould section ejected one behind the other, are aligned in a row, against each other on a guide track. An additional transporting arrangement provides for the movement in steps corresp. to the rate of their prodn, of the row of mould sections along a track leading through a casting zone and a cooling zone. The track supporting the weight of the mouldings is, at least in the cooling zone, stationary, and the additional means of transport consist of compressed air feeds for the creation of an air cushion to support the string of mould sections, at least whilst they are being moved exclusively by the force of the ejector in the modelling chamber. The air cushion is formed by a boxlike stationary track, the upper surface of which has air outlets connected to a compressed air supply. The boxlike track is divided into compartments laid out one behind the other lengthways, and connected individually to the compressed air supply. The surface of the track has, over the range in which the air cushion is to be formed, a lengthways running groove edge strip, or rib, which fits the profile of the mould sections. Between the track and the string of mould section there is a belt which is driven via the mould sections by the ejector. A simple means, without expensive separately driven equipment of moving the row of mould sections with heavy castings along an extended casting and cooling track is provided. The press plunger does not have to exert and excessive load so that the sand is not powdered. Investment costs and operating costs are reduced.
