Patent EP-0276056-A2 (EP)
Inventor: MILLER ALAN LEONARD
IPC: F15B13/044
Filed: 1988-01-07
Abstract: A two stage valve assembly (14) for a fluid control system (10) wherein one stage (48) includes a pressure responsive spring centered spool (50) for regulating fluid flow between a fluid source (16) and a fluid responsive actuator (12) as a function of the spools linear position. The linear position of the spool is determined by oppo­sitely directed pressure based position determining forces one of which may predominate over the other. The other stage (42) of the valve assembly includes an on-off solenoid valve (88) for controlling one of the positioning determining forces. A pulse width modulated circuit (28) has its output coupled to the valve winding (24). The PWM circuit is capable of providing an alternating output sig­nal the duty cyle of which may be varied to effect the position of the spool and thereby the flow to the actuator.

Abstract: A communications system comprises a plurality or network of switching nodes (10,12,14,16,18,20,22) interconnected by transmission links, time division multiplexed signals (2ii,28) being transported between entry nodes (10) and egress nodes (22) as "transactions" comprising a header portion (F1-F2) and a message portion (F3-F4), which may comprise signalling. The header portion (F1-F2) comprises a sequence of node exist address (NEA) which occur in the order in which the nodes will be encountered as the signal traverses the network. In each node (10-20), the leading node exit address (NEA) determines the exit through which the signal will emerge from that node so as to reach the next node in the sequence. The entire sequence of node exit addresses (NEA) is generated by access apparatus (26) at the entry node (10), conveniently by accessing a routing database (46) by means of a unique address (DIA) of a destination interface (26A) connected to an exit of the egress node (22) to which an intended recipient is connected. The destination interface address (DIA) may conveniently be produced by accessing another look-up table (36) using the recipient's directory number (DIR.NUM).

Abstract: The disclosure relates to a labelling mechanism for a weigh/price labelling apparatus comprising a device (10) which supplies printed self-adhesive labels on a backing strip (11) around a stripper block (12) to feed labels onto a temporary holder (13) on which a label is held by vacuum ports in the holder. A label transfer device (16) comprises a carrier (17) mounted for rotary movement on an eccentric drive mechanism (18). Rotation of the drive mechanism moves the carrier (17) from a label receiving position adjacent the holder (13) to a label delivery position for delivering a label to an article. The carrier includes a pad (42) having ports (47) to which vacuum or air pressure can be supplied to hold a label to or discharge a label from the pad. 
     In order to reorientate the label between the pick-up and discharge positions, the pad is mounted on a spindle (43) which is reciprocated in opposite directions by means of two pneumatically operatable piston/rack members (46) movable in bores (45) in the mounting block for the pads. The stroke of the pistons can be adjusted so that the pad can be orientated as required to suit the article to which the label is to be applied.

Abstract: The improved operational amplifier stages are an input (601), a gain (603) and an output stage (605). The input stage (601) has a differential buffer amplifier (Q101,Q102,­R1A,R1B,R2A,R2B) connected to a transconductance section (Q1,Q2) for converting a differential voltage signal to a current signal. The input stage (601) is operable within a range of differential voltage signals, the range including common mode voltage signals at or beyond the negative supply rail (7). The gain stage (603) has two cascaded transistors (Q3,Q4). The base of the first transistor (Q4) is connected to the emitter of the second transistor (Q3) through an integrating capacitor (C1). The capacitor (C1) is further connected through a resistor (R3) to the negative supply rail (7). The output stage (605) has a driving amplifier and two common emitter output transistors (Q106,Q9). One output transistor (Q106) is driven by the amplifier through two current mirrors (Q103A,Q103B;Q6,Q7) the output of the second current mirror being compared to a reference current source. The other output transistor (Q9) is driven directly by the amplifier.

Abstract: The electronic driving-time control device according to the invention serves for use in motor vehicles, especially long-distance heavy-goods vehicles, to monitor adherence to the drivers' driving times permissible in a particular 24-hour period or to monitor adherence to the necessary stop times. It has hitherto been found disadvantageous that, in view of the large number of long-distance lorries travelling on main roads, the traffic police have had only inadequate facilities for checking the monitoring of adherence to the drivers' driving time permissible in a 24-hour period. The object on which the invention is based is to provide an electronic driving-time control device for motor vehicles, which gives everyone, during the day and at night, a clearly visible indication of adherence to the permissible driving time or rest time of drivers. The object is achieved in that signal devices controllable by an electronic circuit of the device and designed in the form of traffic lights are arranged at a location on the vehicle clearly visible to anyone from outside the latter. <IMAGE>

The head base moves corresponding to the shape of the cam and in association with the operation of the planetary gear. Operation such as recording and playing is carried out on the tape by the movement of the head base.

Abstract: To adjust the frequency of odd mode transverse waves propagating in a SAW resonator device (30) a pair of localized regions (40′, 40′′) of frequency determining trimming material are deposited onto selected portions of a surface wave propagating surface (31a), where the odd order transverse mode has energy maxima. These regions change (40′, 40′′) the acoustic properties and hence the velocity characteristics of the surface wave propagating surface. The frequency of the odd mode transverse wave is changed to match that of the fundamental transverse propagating wave. This decreases the insertion loss of the resonator device (30) at the fundamental frequency and eliminates the odd mode transverse wave propagation characteristic within the operating frequency range of the resonator device (30). An acoustically matched piezoelectric transparent cover (38) disposed over the surface wave propagating surface (31a) has disposed thereon a trim pad (39) which is selectively ablated to provide the localized regions (40′, 40′′)
