In operation piston 3 is moved in the direction of arrow A and causes dyeing liquor to pass in the direction of arrows 19 from the region C above the piston through passages 22 and the textile material 7 to be returned to lower region D of inner cylinder 2. Piston 3 is then moved in the direction of arrow B and the dyeing liquor is passed through the material 7 in the opposite direction to region C, thus achieving prevention of stagnation of dyeing liquor in any part of the apparatus. Heating means 16 and a cooling jacket 15 may be provided round inner cylinder 2 for heating the dyeing liquor during dyeing and for cooling it when the dyeing process is completed. The progress of the dyeing operation may be observed through openings 14 in container 1 which are Covered by glass cylinder 10 inside the container.

The air flow through the passages 17 is controlled by a valve assembly 23 including check valves 32 which open and close in response to pressure waves generated in the exhaust system during at least the lower half of the engine speed range. The distance between the exhaust pipe inter-connection 63 and the combustion chamber most remote from the inter-connection which is connected to the respective manifold 13 or 14 is greater than six and less than fourteen feet and may be calculated from a formula given in the Specification which involves the flow area of the exhaust pipe,the engine speed for maximum induced air flow and the volume of the exhaust manifold. The pipes 61 and 62 may be connected to a common silencer (64), Figs. 6 and 8 (not shown), with the pipes being of the same or different lengths, or connected to respective silencers and the inter-connection provided by a connecting pipe (66) Fig. 10 (not shown), upstream of the silencers. The valve assembly (23) includes, in addition to the reed check valves 32, a valve 31 operated by a diaphragm 35, subjected to the intake manifold suction, which prevents air flow through the assembly on engine deceleration engaging a seat 48. Communication between the chambers 38 and 43 on opposite sides of the diaphragm is controlled by restriction (55), Fig.5a (not shown), defined between the base of the valve stem 42 and a flexible metal slate 41 to provide a controller time delay in opening of the valve 31. Mixture flowing to the engine through a passage 74 is heated by exhaust gas flowing through a chamber 72 communicating through a passage 71 and pipe 73 with the exhaust system of the combustion chambers associated with the manifold 13.

Title: Pulse-signal synchronization circuits
IPC: H04J13/00
Filed: 1973-11-06
Abstract: 1450022 Synchronization in pulse transmission systems FUJITSU Ltd 6 Nov 1973 [6 Nov 1972] 51540/73 Heading H4M In order that a received pulse signal may be synchronized at the receiving station, e.g. in PCM time division multiple access transmission used in satellite communication, a synchronizing signal W which is a combination of a predetermined (e.g. pseudo random code) pulse form and external clock pulses is transmitted with the information signals (e.g. in a preceding multiplex frame) and applied to an input of a comparison arrangement I in the receiver. To a second input of this arrangement is applied a comparison signal PN of the predetermined form from a signal generator 7. This generator operates in dependence on internal clock pulses from a voltage controlled oscillator 5; these clock pulses are moreover phase shifted by #/2 in a delay unit 6 and fed to a third input of the comparison arrangement I. The comparison output from the arrangement will be a voltage representing the phase difference between the internally generated predetermined signal PN and the received signal W, and in the prior art this voltage is applied directly to the input of the voltage controlled oscillator to control the internal clock pulse frequency. In such a system however, the possibility exists that the system will synchronize at a spurious pseudo-stable point in the relation between the comparison output and the phase difference between W and PN. To prevent this possibility the system according to the invention provides a further comparison circuit II which provides an output 8 representing the phase relationship between the external clock pulses in the received signal and the internal-clock pulse (not phase shifted) and a switching arrangement 4 which normally acts to apply a constant voltage + V to the oscillator. The output from the comparison circuit II is applied to a level detector 10 which senses when the output is above a preselected threshold and causes the switching arrangement 4 to operate such that the output from the first comparison arrangement I is applied to the voltage controlled oscillator. The preselected threshold is set such that the phase lock loop synchronization arrangement only operates in the region of a genuine stable synchronization point. In order to reduce the time which might be necessary to achieve synchronization, a further level detector 11 may be used to sense the output from the comparison circuit II, and when this is below a predetermined threshold (in the opposite sense to the preselected threshold), a phase shift of # is inserted at 12 into the clock pulses being applied to the comparison circuit. This enables the maximum period necessary to be sure of achieving synchronization to be reduced from two frames to one.
