Abstract: An arrangement for the encrypted transmission of information items, particularly speech, by means of a controllable memory device (S), into which the incoming information items are successively stored, subdivided into time elements (1, 2, 3, 4, 5; 1', 2', 3', 4', 5') at the transmitting end are read out again exchanged in time with respect to one another for their transmission and in which this exchanging of the time elements is cancelled at the receiving end, and in which the control clock pulses for the memory device at the transmitting and the receiving end are in each case extracted from the clock of the clock generator (TG). In this arrangement, the clock generator is constructed to be controllable in its frequency for blurring the time boundaries of the time elements with the aim of an increased degree of security of the encryption, and its frequency is controlled in a pseudo-random manner by means of a random noise generator (QZG). <IMAGE>

Abstract: The method enables the desired tap temperature to be obtained during subsurface pneumatic refining of carbon steel or low alloy steel, without the need to reblow the heat, by adding to the melt, before starting the injection of refining oxygen, a fast oxidizing element such as aluminum, and a slow oxidizing element such as silicon. The amount of fast oxidizing element added is such that the total amount is sufficient, when oxidized, to raise the temperature of the melt to the desired temperature before substantial decarburization begins, and the amount of slow oxidizing element added is such that the total amount is sufficient, when oxidized, to maintain the temperature of the melt within the desired temperature range during the decarburization period.

Abstract: Apparatus for collecting eggs (E) from a number of poultry cages (21) includes a collector conveyor belt (30) for receiving the eggs (E) from the cages (21), and a ramp conveyor belt (40) for de-escalating the eggs (E) from the collector conveyor belt (30). The cage bottoms are extended to provide a trough in which the collector conveyor belt (30) is carried. Opposite the cages (21), strips (35) of low-friction material act as bumpers to maintain without damage eggs upon the collector conveyor belt (30). A diagonal fence is provided above the collector-ramp belt conveyor junction point to encourage easy, undamaged egg transfer action from the collector conveyor belt (30) to the ramp conveyor belt (40). Resilient fingers mounted in rows upon the ramp conveyor belt (40) encourage undamaged egg de-escalation.

Abstract: A frangible cartridge for anchoring a reinforcing element such as a rock-bolt in a borehole in rock strata, for example an underground mine roof, contains as separate components (A) a hydraulic substance mixed with a non-aqueous water-miscible liquid which is inert with respect thereto to form a paste-like mass and (B) an aqueous liquid, preferably water, which is capable of reacting with the hydraulic substance in component A on being brought into contact therewith when in use a reinforcing element is caused to break the cartridge and mix together components A and B within the borehole so as to form a cementitious grout around the reinforcing element, said grout serving when hardened to anchor the reinforcing element in the borehole. This cartridge is safer for use in coal mines and the like than the conventional resinous cartridges and is more reliable than cartridges in which the hydraulic substance is present in a dry form.
