Hydraulic cylinder means 255 control the pivoting movements of the workhead between adjustable limit stops and hydraulic means similarly control the sliding movements towards and away from the tool cradle. Means are provided in the respective hydraulic cylinders, for damping the movements at the ends of the strokes so as to prevent sudden abutment with the limit stops. The workhead 240 is vertically adjustable on the swinging base 250. The machine is generally similar to that described in Specification 1,280,162 and the generating train which interconnects the work spindle and tool cradle is as described in Specifications 1,280,163 and 1,280,167. The machine may be a double machine incorporating two tool cradles with corresponding workhead assemblies arranged adjacent thereto and it is envisaged that two such double machines may be arranged in a continuous production line for effecting two roughing and two finishing operations on each blank, suitable work loading and conveying apparatus being disposed adjacent the machines.

Abstract: A backpack having a front panel normally riding on the back of the wearer according to this invention has a front panel which is vertically elongated and which is formed of an at least semirigid shell having a shape generally complementary to that of the back of the wearer and constucted to be relatively bendable longitudinally and relatively stiff transversely. Thus the panel can bend forward and back, that is about a horizontal axis, but cannot flex about a vertical axis. This is achieved by forming the shell with transverse rigidifying formations so it is longitudinally relatively bendable and transversely relatively stiff. These formations according to this invention are ridges or grooves.

Abstract: This method, which allows the synchronisation of two periodic signals of like shape and of like theoretical period, is of the type in which the second signal is synthesised iteratively with a fitted phase depending on a measurement of correlation between the first and second signals. Synchronisation is achieved through a progressive shifting of the phase of the second signal until a correlation minimum is detected, after which this signal is locked onto the correlation peak by phase hopping either side of the latter.

In such an oscillator circuit, an audio signal having a frequency in the range of 20 Hz . . . 20 kHz is coupled into the oscillator circuit, is modulated with a high frequency and is emitted in the form of an RF audio signal having a frequency of more than 2 MHz. Such an oscillator circuit is used for instance in an infrared transmitting unit, wherein a low frequency audio signal is transformed into a higher frequency infrared signal. The higher frequency audio signals are transmitted via infrared channel to an appropriate receiving unit-for instance to infrared head phones-which comprises a receiving unit having an appropriate demodulator and preferably also a stereo-decoder in order to reproduce the low frequency audio signals. The oscillator for stabilizing the amplitude of a high frequency oscillation comprises a resonant circuit which is coupled with a first transistor having a base terminal, an emitter contact, and a collector contact. The first transistor develops an output voltage at the emitter contact which is fed back into a base circuit of the first transistor. The collector contact of the first transistor is coupled to a supply voltage source. The supply voltage source is coupled to the base terminal of the first transistor via a resistor. The emitter contact of the first transistor is coupled with the base terminal of a second transistor. The second transistor has a collector contact which is connected to the base terminal of the first transistor for controlling the voltage at the base terminal of the first transistor.
