Abstract: ABSTRACT OF THE DISCLOSURE               A vehicle brake having a pair of brake shoes move-ably mounted and arranged in end-to-end relationship on a fixed backing plate.  A pair of levers is pivotally mounted on the backing plate.  The levers have thrust transmitting portions which are interposed between a pair of opposed brake shoe ends and a hydraulic service brake actuator for moving the brake shoes into engagement with the brake drum.  The levers also have swinging end portions which pivot inwardly in opposite directions upon outward movement of the thrust transmitting portions.  The lever  thrust portions have concavely curved camming surfaces which slidably engage complementary convexly curved brake shoe end surface for transmitting the hydraulic actuator force to the brake shoes.  A mechanically actuated parking brake mechanism is mounted on the backing plate and is operatively connected to the lever swing end portions by a pair of links.  One end of each link is operatively connected by a pin within a slotted end of an actuating handle, with the other link ends being slotted and movably connected to the lever swinging end portions.  Ac-tuation of the handle by a parking brake actuating force pivots the lever swinging end portions inwardly through the connecting links which in turn expand the brake shoes outwardly into en-gagement with the drum through the resulting outward movement of the lever thrust portions.

Abstract: ABSTRACT OF THE DISCLOSURE A device limits the oxidation of the surface of hot metallic dross by preventing access of oxygen to the dross. This device comprises a metal bell which is open at the bottom and can be moved vertically, a concrete base standing in a tank containing water and a shallow container for holding the dross. The bell exhibits a number of metallic supports projecting out of its lower edge to support the bell as it rests in the water filled tank. This arrangement provides an air-tight seal for the space inside the bell and allows for compensation of pressure change inside the bell as the hot dross consumes the limited amount of oxygen in the air inside the bell.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure describes a method for a two-step heat treatment of corn with electromagnetic oscillation in the range of micro-waves or infra-red radiation.  This is done by heating corn in a first step during 5 - 120 seconds from ambient temp-erature to 100° - 200° C with infra-red rays or electromagnetic waves having a wave length of 0.7 - 0.1 m.  In a second step the corn is kept for 5 - 200 seconds at the temperature reached during the first step or at a temperature not more than 10% higher than the last named temperature and/or the temperature is gradu-ally decreased down to 60°C at the most.  During the first step the temperature is controlled by setting up the intensity of infra-red rays or electromagnetic waves to the wave length 0.7 -0.1 m and the temperature remains unchanged during the second step.  Finally, there is crushing or flaking of the corn when hot which is then cooled down below 40°C.  The disclosure also describes a device which comprises a feed hopper, an adjust-able feeder to feed the corn from the feed hopper to a horizontal or slightly inclined carrier mechanism, the carrier mechanism be-ing followed by a crusher, then a cooler.  The carrier mechanism comprises a belt or vibratory conveyer and means for adjusting the carrier speed of the carrier, infra-red radiators adapted to irradiate a first step constituting 20% - 90% of the length of the carrier mechanism, electric resistor heating means to heat the remaining second step constituting 80% - 10% of the length of said carrier mechanism, the lower portion and sides of at least part of the carrier mechanism being thermally insulated, the car-rier mechanism in the second step being at least insulated and provided with a thermally insulated upper cover.

Abstract: ABSTRACT OF THE DISCLOSURE A method of, and apparatus for, enciphering and deciphering audio information which is subdivided into partial blocks along a time axis, the partial blocks being mutually interchangeable according to key information. The incoming analog audio signals are subdivided into a number of frequency bands, each of which is assigned to an information channel.  The analog audio signals of each information channel are converted into digital sig-nals which are subdivided into main blocks along the time axis. The main blocks of equal time of each information channel are subdivided into sub-sections of the same magnitude with respect to time and which are inter-changed, in accordance with the key information with sub-sections of the same main block or with sub-sections of a time-equal (i.e. isochronal) main block of another information channel.  After the interchange in each infor-mation channel, the digital signals are converted into analog signals and grouping together of the interchanged sub-sections are grouped together into new main blocks, in order to render possible a further processing of the time-equal or isochronal new main blocks of each information channel.

Abstract: ABSTRACT OF THE DISCLOSURE          Swathed grain is picked up by a conventional pick-up and fed into the side of one end of a transversely situat-ed rotary impeller assembly which moves the crop in a spiral motion against threshing grates on the lower portion and spiral fins on the upper portion.  The crop reaches the other end of the impeller assembly and is transferred to one end of a se-cond transversely situated rotary impeller assembly whereupon the action is repeated until the crop reaches the other end of the second assembly whereupon the crop with the majority of grain removed, is discharged at right angles to the axis of the impeller assembly and into a final beater assembly.  The threshed and separated grain falls from the impeller assemblies to a grain pan and is cleaned by two sieve assemblies which extend the full width of the impeller assemblies.  Unthreshed grain is returned to a re-threshing unit mounted at one end of the beater.  The crop is threshed by a flailing action and separated centrifugally as it passes through the impeller as-sembly.  Another embodiment divides the crop in the first rotary impeller assembly and moves it outwardly towards the ends thereof whereupon it is transferred to the second rotary impeller assembly which then moves it towards the center and discharges it centrally.  A further embodiment utilizes one transverse rotary impeller assembly which divides the crop and moves it outwardly to each end and then discharges it at each end of the impeller assembly into each end of a trans-verse auger assembly which further separates the grain and discharges the remaining crop against a curtain whereupon it falls upon a straw walker assembly which further separates the grain from the straw.
