Abstract: Tylosin derivatives represented by the following general formula (I):
      [wherein R denotes a hydrogen atom, acetyl, propionyl or a radical of Si(R²)₃ (in which R² is a lower alkyl group), and R¹ stands for a hydrogen atom or a radical of Si(R²)₃] are novel compounds, which are useful as intermediates for the synthesis of 4˝-acyl derivatives of tylosin because, after introduction of any desired acyl group at the 4˝-hydroxyl group, the silyl protective group can be readily removed without liberation of said acyl group. 
     This invention also provides processes for producing said tylosin derivatives. More specifically, it provides a method of selectively protecting 2′- and 4‴-hydroxyl groups of tylosin (those of higher reactivity among the hydroxyl groups involved); a method of selectively protecting only the 4‴-hydroxyl group of   tylosin; a method of selectively protecting the 3- and 4‴-hydroxyl groups of 2′-O-acyltylosin; and a method of protecting 3-, 2′- and 4‴-hydroxyl groups of tylosin.

Abstract: In a switchgear (1) for the variable power operation of a heating applicance (2) or the like, with the aid of a control device (8) operating in a pulsed manner, the operating element (11) is designed such that it switches off a control heater (10) of the control device (8) not only in the switched-off position but also in higher adjustment regions and in the highest adjustment region (16) and does not switch on until lower adjustment regions (17, 18) are reached and in the event of manual switching over of the switchgear (1) from the highest adjustment region (16) to a lower adjustment region (17, 18), the pulsing cycle is forced to start with a switched-on position of the energy switching contact (6). In consequence, the switchgear (1) is especially suitable for the operation of low capacitance heating appliances, such as microwave appliances, and can be produced simply by redesigning a cam disc (13) of the operating element (11) of previous switchgears. <IMAGE>
