An additive is pre-mixed with the swarf which, when the billet is heated, reacts to form an atmosphere inside the jecket which displaces or prevents the formation of carbon dioxide and/or other gases which at elevated temperatures would oxidise the stainless steel to form chrome oxides at the interface between the jacket and the core. The additive is preferably in powder form. Examples of suitable additives include urea and ammonium chloride.

Abstract: The invention relates to a method and a signal-switching system for setting the system cycle or the cycle of a digital switching system having at least one synchronising unit with a controllable cycle generator, which system obtains the digital signals from numerous external digital conductors with predetermined cycle frequencies, or emits signals to be sent to these conductors, whereby the fixed cycle frequencies, which cannot be affected, of numerous digital conductors are made use of for external synchronisation or equalisation of the system cycle produced by the system's own synchronisation unit.It is provided according to the invention that the difference values between the system cycle and many cycle frequencies are determined or the cycle frequencies are directly measured and many of the measured cycle frequencies are compared to the prevailing system cycle, and the respective difference values are determined, and that depending on these difference values or by using statistical methods and/or evaluation or comparison criteria, the system cycle is either equalised to a selected cycle frequency, or a correction value is determined for the prevailing system cycle.<IMAGE>

Title: Grain stock container installation
IPC: B07B1/00
Filed: 1988-06-20
Granted: 1994-11-25
Abstract: The invention relates to a grain stock container installation for easy, completely chemical-free and poison-free protection of grain stocks especially against the worst cereal pests the grain weevil (sitophilus granarius) and the rice weevil (sitophilus oryzae). It renders superfluous the otherwise necessary continuous agitation of the grain stock. The installation is adapted closely to the life instincts and behaviour patterns of these cereal pests and consists essentially of a container 1 which is perforated in a sieve-like manner and is preferably a drum-sieve container or a riddle container, and a collecting tray 2 located underneath. In order that no cereal grains but all cereal pests fall or are sieved out of the container, the widths of the container sieve openings are at least 1.5 millimetres, preferably roughly 3 millimetres. The collecting tray has side walls 4 which are inclined inwards at an angle in the upward direction and have a smooth internal surface made of hard material, preferably glass. As a result, the cereal pests cannot escape from the tray again and can easily be collected and removed. <IMAGE>

Abstract: An improved electrical drive circuit for a reversible electric stepping motor of the type having a coil supplied with electrical pulses to cause step-by-step rotation of a magnetized rotor, where the rotor includes additional magnetic poles for locking the rotor between steps in a stable equilibrium located so as to reduce the energy of pulses required to produce normal forward rotation of the rotor. Forward rotation is produced by a switching circuit which periodically connects a voltage source and energy dissipating means in circuit with the coil for pre-determined time intervals in a forward switching cycle. The reverse rotation switching cycle includes one or more pulse portions in the forward rotation to pre-position the rotor for reversal. Preparatory to reversal, the reverse switching cycle applied to the motor coil includes a train of high frequency pulses which reduce the electromagnetic torque in the forward rotational direction and control coil current.
