[Classes 12 (i), 12 (ii) and 12 (iii).] The housing of a pivoted-block shaft bearing is formed with three oil chambers 13, 33, 34 communicating with each other through passages 15 in dividing walls 27, 35 which closely surround the shaft 6, impurities being separated in the outer chambers 33, 34 while the purified oil flows to the middle chamber 13 whence it is raised to a receptacle 22, in which the bearing blocks 8 run, by a loose ring 23 or a disc secured to the shaft. Alternatively, the blocks may run directly in the oil in the middle chamber. The passages 15 may be arranged above the bottom of the chambers 33, 34 so that impurities settle in those chambers, or a cylindrical gauze filter 16 may extend through the passages.

A valve assembly associated with an anaesthetic mask has an outlet valve closed by a spring, the tension of which can be adjusted from the exterior of the housing, and an inlet valve which is freely movable between its closed and open positions. The tubular housing 13 has a connection, not shown, for attachment to the mask, and a lateral extension 15 enclosing the outlet valve 21. This is held against its seating 19 by a spring 22, the outer end of which bears against a plug 25 screwed into the member 15 so that the tension of the spring may be adjusted by altering the setting of the knurled head 27.

Abstract: 1450578 Automatic phase control, transistor pulse circuits SIEMENS AG 21 Sept 1973 [29 Sept 1972] 40661/73 Headings H3A and H3T In a stabilized oscillator circuit in which the phase and frequency are controlled by a control loop including a phase discriminator of the type in which a reference oscillator provides sampling pulses which gate the stabilized oscillator output to provide a control signal for the stabilized oscillator, the stabilized oscillator output is fed to the discriminator via a pulse shaper which produces output pulses having a, first portion A of identical shape and duration during each pulse and a variable duration residual portion such that the mean value of each pulse varies in dependence on its duration to provide frequency control. The output of the oscillator whose frequency is to be controlled is converted to a rectangular waveform which is then applied to input Vos of a pulse shaper circuit, Fig. 1. The rectangular pulses are differentiated by C1, R1, and theresulting negative going spikes turn off transistor T1 to produce a train of positive going narrow pulses at its collector which are applied to transistor T3 via a buffer T2. Each time a positive pulse occurs, C2 charges and, following the rear flank of the positive pulse, transistor T3 is blocked for a period determined by the time constant of R4, C2. While T3 is blocked, Miller circuit C3, T4 produces a linear ramp A, Fig. 3 at the collector of T4. While T3 is conductive, T4 is cut off and its collector remains at a high potential, C, until T3 is again cut off. During section B transistor T4 is saturated. Since the duration from t 1  to t 2  is fixed by the time constants of the circuit, and the overall duration from t 1  to t 3  varies with the input frequency, the period t 2  to t 3  in which the signal is at a constant level, and hence the mean voltage level, will also vary with frequency.
