Abstract: Modern subscriber equipment usually comprises combinations of different units. In order to simplify the operation of the different units or unit functions for the user, a program-controlled control device is normally disposed in the subscriber equipment. Modern subscriber equipment may on the one hand simplify the work of the user, but on the other hand it also requires specialist knowledge and a great deal of experience, particularly in the light of the ever-increasing range of communications tasks. The new subscriber equipment requires no specialist knowledge on the part of the user for the communication process, since the user can set up a connection to a called subscriber in the normal manner. Only the transmission of the information temporarily stored in the subscriber equipment is performed automatically, where the control devices, in dialogue with one another, control the read-out, transmission and storage of the information. The new subscriber equipment enables the automatic transmission of any temporarily stored information in differently designed communication networks for established connections. <IMAGE>

Abstract: A power assisted vehicle steering system of the speed responsive kind has a ram 6 fluid flow to chambers 4 and 5 of which from a pump 9 is directed by an open centre steering valve 1. Communication between the chambers 4 and 5 is permissible through a by-pass valve 13 adjustable by a solenoid 17 in response to vehicle speed to open such communication as speed increases (and thereby decrease power assistance) and vice versa. The valve 13 has a spool 22 which is spring loaded relative to a control spindle 18 of the solenoid. Adjustment of the spool 22 in response to speed variations opens or closes by-pass ports 14 and 15 to opposite ends of a restrictor 32 which provides such fluid flow communication. 
     A spring loaded spool 41 in the valve 13 is responsive through chambers 39 and 40 to fluid pressure at opposite sides of the restrictor 32. When the fluid pressure differential across the restrictor 32 exceeds a predetermined differential, the spool 41 is displaced to direct fluid pressure to spool chamber 55. This displaces the spool 22 against its spring biasing 27 and relative to the rod 18 thereby closing the ports 14 and 15 (and communication between the ram chambers) so that increased power assistance becomes available irrespective of the vehicle being at high speed.

Abstract: A vehicle transmission has a main shaft (9 ) and a parallel counter shaft (10) with a plurality of selectable gear trains therebetween. The axis of the engine crankshaft (14) is disposed perpendicular to intermediate portions of the main shaft and the counter shaft, with the low speed gear trains (G1,G2 ) and high speed gear trains (G4-G7) positioned on opposite lateral sides of the crankshaft. This results not only in a reduced size of the transmission in the axial direction of the crankshaft but also in a reduced lateral size of the transmission, as compared with a transmission in which the crankshaft is connected in series to the transmission main shaft. A synchro mechanism (S12,S34,S56,S7) is mounted on the counter shaft and a shaft drum (64) for operating the synchro mechanism is positioned parallel to the counter shaft. This insures a space for disposition of the synchro mechanism between gears of the relatively large diameter gears on the counter shaft and ensures a smooth shifting operation, without an increase in the lateral size of the transmission due to the shift drum.
