Title: Air monitor for hay-aerating systems
Inventor: WILD JOSEF
IPC: A01F25/08
Filed: 1976-03-05
Abstract: The monitor has a handle (3) with a dimensionally stable frame (1) and a porous cloth piece (2) fastened to it. In order to determine the air permeability of a haystack, the frame (1) together with the cloth (2) is applied to test points on the haystack surface. If blower air escapes at the test point, the cloth arches upwards in a dome-like manner, specifically more or less tautly according to the quantity of outflowing air. It can thereby be determined whether the haystack is being aerated uniformly. If a long handle (3) is used, there is no need for the tester to step onto the haystack. <IMAGE>

Title: Braking-magnet arrangement for an electrical measuring instrument
Inventor: KONASHINSKY JURY ALEXANDROVICH
IPC: G01R11/10
Filed: 1978-10-17
Abstract: The braking magnet arrangement used, particularly, for an electricity meter exhibits two permanent magnets (1, 2) arranged in a holder (4). A rotor disc (3), on which a braking torque generated by the braking magnet arrangement is exerted, moves through the air gap provided between the two permanent magnets (1, 2). The two permanent magnets (1, 2) are arranged in such a manner that their direction of magnetisation extends parallel to the surface of the rotor disc (3) located in the gap. Such an arrangement allows the dimensions of the braking magnet arrangement and the material required for the permanent magnets (1, 2) to be reduced. <IMAGE>

Title: Windscreen wiper with intermittent action - has adjustable switch for setting time interval between wiping periods
IPC: B60S1/08
Filed: 1972-11-30
Abstract: The windscreen wiper switch is connected to a time interval adjusting switch which can be adjusted in such a manner that the wiper is stopped in one end position of its travel for the required time period. After the windscreen wiper is switched on it is necessary only to rotate the knob of the time interval switch from normal operation to maximum delay. The windscreen wiper switch actuates the motor which drives the windscreen wiper. The time interval is set by the switch. The time interval switch has a rest and a working contact. The circuit ensures also that the windscreen wiper is not stopped in the field of vision but only at the end of its travel position or in its parking position.

Title: Single crystal prodn - from two components by reaction and epitaxial growth in two steps in one apparatus
IPC: C30B11/14
Filed: 1970-12-11
Granted: 1972-07-21
Abstract: Prodn. of a rod shaped single crystal of a cpd. by a reaction step and a crystallisation step in which during the reaction a first liquid component is reacted with a second gaseous component while controlling the amounts of reactants and in which the reactants are retained in a close tube in stoichiometric proportions. During the crystallisation step the gas phase contacts a seed crystal which grows in the direction of the seed crystal - gas phase positive temp. gradient. Before the reaction step, the seed crystal is arranged to sit at a higher level than the liquid phase so that it does not contact the melt during the greater part of the reaction step. The fluid amount incases and hence the fluid eventually contacts the seed crystal setting off the melting process. Used for semiconductor single crystals.
