Title: Milling and sieving cement clinker with gypsum and slag - in plant designed to produce cement with very consistent properties (OE 15.2.77)
Inventor: HIETTLER HANS ING
IPC: B02C25/00
Filed: 1976-11-11
Abstract: Granular material is milled and sieved in a closed circuit to obtain a stream of fine material which is the finished prod. and coarse material which is recycled through the mill. A constant throughput is maintained by altering the sepn. limits of >=1 sieves according to the wt. of coarse material obtd. from the sieves, the amt. of finished prod. with the required fineness being constant. The wt. of coarse material is pref. adjusted by varying the throughput of a bucket elevator or pneumatic hoist receiving the milled material. When the cement clinker is difficult to mill, coarser sepg. limits are used for the sieves, and finer limits are used for clinker which is easy to mill. The pref. plant includes weighing machines and a controller comparing actual values with standard values. Used for mixing clinker with crude gypsum and blast furnace slag under constant milling conditions at rates >200 t/h, to obtain cement with very consistent values of compressive strength.

Patent DE-2657430-A1 (DE)
Inventor: UNDERWOOD MICHAEL JOHN
IPC: G10L19/00
Filed: 1976-12-17
Abstract: Speech synthesizing apparatus is provided in which different sounds are required for a plurality of channels. The channels are polled in turn on a cyclic scanning basis, the scan for each channel occupying a channel sampling period during which an instantaneous value is generated for the amplitude of a voiced sound component. Values representing instantaneous amplitudes of each of a plurality of unvoiced sounds are separately generated in turn during the period occupied by the scanning of all the channels and these values are stored. A selected one of the unvoiced sound values is extracted from the store as required for a particular channel during the sampling period for that channel, so that an updated value for the unvoiced sound is available on each occasion that that particular channel is sampled. The voiced and unvoiced sound values are then combined during the appropriate sampling periods. The required sound combinations are specified by parameters expressed in digital form for each channel separately.

Title: Cold preservation of beverages fruits and vegetables - using air circulation over evaporator coil and aeration orifices in cabinet walls (SW 28.8.78)
IPC: F25D17/06
Filed: 1977-12-23
Abstract: Cold preservation process for fresh prods., such as fruit, vegetables, wines and other drinks is effected in a freezing cabinet equipped with an evaporator traversed by a cold-producing substance which lowers the temp. of the air in the space and is arranged in a current of air. A partition is fitted against the rear wall of the cabinet and is secured by screws; it consists of a corrugated plastic sheet and suction slits, cut in the sheet, allow the fan to suck in air which is directed, by the deflectors, over the evaporator which is fitted with fins and fixed to the rear wall of the cabinet. The current of air flows downwards and it is rapidly chilled on passing to the inside of the cabinet. Permanent ventilation of the prods. is ensured without stagnant prock pockets of air. The air flow meets a collecting dish filled with condensed water which tends to prevent the prods. from becoming dehydrated. The dish is located over the compressor so that the air from the fan is charged with a higher amt. of moisture. The cabinet has a very high freezing power which can be obtd. with an evaporator which has double the surface of the usual type but takes up little room. Owing to the fact that the prods. to be preserved are in a current of air at a temp. >0 degree C., which is constantly renewed, they can be kept for several months without any redn. in quality.
