Title: Vehicle
IPC: B61F5/38
Filed: 1974-10-31
Abstract: 1480806 Rail vehicles AUTOMATISK DOSERINGSKOMPENSATOR AB 31 Oct 1974 47216/74 Heading B7L A rail vehicle has a body 1 carried by a bogie with a frame 3 on each side of which is mounted at least one fluid operated piston-cylinder device 5 connected through upwardly and downwardly swinging arms 11 to axles 12 carrying pairs of wheels 13, the devices 5 acting on the arms 11 to hold the frame 3 above the rails 21 and being operable when the vehicle travels through a curve to swing the arms 11 at respective sides of the frame such that one side of the frame is lowered and the other raised whereby the frame 3 and body 1 are inclined laterally towards the centre of the curve, the body 1 being connected to the frame by pivoted links 2 which enable the body to move laterally away from the curve centre in a substantially horizontal direction, the horizontal movement being controlled by a control device such that the combined inclination and horizontal movement of the body as the vehicle moves through a curve results in passengers and/or goods at positions spaced from the longitudinal axis of the vehicle being caused to move in a substantially vertical path. In the Fig. 1 embodiment each side of the frame 3 carries a cylinder in which slide two pistons 7 with rods 7<SP>1</SP> each connected by a link 8 to a respective arm 11 in turn connected to a respective axle 12. When the vehicle travels round a curve the side of the frame 3 closest the curve centre is lowered by swinging the arms 11 on that side upwardly from the position shown in Fig. 1 which also causes the wheels 13 on this side to be moved closer together. The side of the frame 3 remote from the curve centre is raised by swinging of the arms 11 on that side downwardly from the position shown in Fig. 1 which causes the wheels 13 on this side to be kept at a greater distance apart than the wheels 13 on the lowered side so that the vehicle is effectively steered through the curve. The device for controlling horizontal lateral movement of the body 1 is a piston-cylinder device 23, 23<SP>1</SP> which may be incorporated in the same fluid circuit as the devices 5 as shown in Fig. 3 or may be in a separate fluid circuit and arranged to operate in response to operation of the devices 5 (Fig. 5, not shown). Fig. 7 illustrates a bogie split into two parts 56, 57 each carrying an end of a respective body 1 and each inclinable laterally independently of the other by means of its own piston-cylinder devices 59 or 60.

Title: Improvements in or relating to telecommunications exchange systems
IPC: H04Q3/58
Filed: 1969-09-29
Abstract: 1,244,396. Automatic exchange systems. SIEMENS A.G. 29 Sept., 1969 [30 Sept., 1968], No. 47754/69. Heading H4K. In a remote concentrator equipped with a remanent relay switching network, a calling subscriber is connected through to one of a plurality of free junctions under the control of a line-identifying counter which is controlled from the main exchange over a speech or control junction by bipolar pulses. At each step a transistor bridge circuit, which effectively (due to a contact chain of the counter) includes in one arm only that subscriber line indicated by the step, is caused to test the loop resistance via contacts of the line's cut-off relay (T). If this indicates a calling condition the next (opposite polarity) pulse from the parent exchange brings up a marking relay (M) pertaining to this subscriber instead of, as usual, stepping the counter. The pulses normally encounter a loop through the counter and its associated circuitry so that elimination of the return pulse when the marker relay operates is effective to identify the caller (on a similar counter) at the parent exchange. The next pulse restarts the counter which is then stepped on without further interruption by subsequent pulses until it reaches its last stage. Power for operating the counter relays (Z), the marker relays (M), the cut-off or busy relays (T) and the switching relays (K) is derived from capacitors that are charged by the bipolar pulses and discharged via transistor amplifiers through the relays during the pauses between pulses. Two transistor bridges (B1, B2) and two associated thyristors (Th1, Th2) are provided for responding to opposite polarity pulses thereby speeding the operation of the counter. The latter may be stepped by the pulses to a particular line when an incoming call is to be set-up. The system is said to be not susceptible to serial voltages (presumably earth currents) on the junctions.

Filed: 1963-12-04
Abstract: 1,038,201. Selective signalling; counting apparatus. GENERAL SIGNAL CORPORATION. Dec. 4, 1963 [Dec. 12, 1962] No. 47856/63. Headings G4A and G4H. In a system for analysing the passage of road vehicles past an observation point a count is made of all the vehicles that pass the observation point in each minute, a count is made of all the high vehicles that pass in each minute, and the times taken by all the vehicles to pass the observation point in each minute are accumulated, this sum giving the percentage of each minute that a vehicle-or part of a vehicle -is actually opposite the observation point which, with high traffic densities, approximates to the percentage occupancy of the traffic lane under observation. As described the presence of vehicles in each of three traffic lanes is detected by three pairs of ultra-sonic transmitters and receivers on an overhead gantry, Figs. 3A, 3B. In the absence of a vehicle an ultra-sonic pulse from a transmitter is reflected by the road surface to the corresponding receiver. In the presence of a vehicle the time taken for the reflection is shorter, and in the presence of a high vehicle shorter still. The reflection times are analysed by a circuit (Fig. 4, not shown) including three mono-stable circuits having appropriate delays, so as to energize an all vehicle relay (AV) while any vehicle is present, and a high vehicle (HV) relay when a high vehicle is present. Actuation of these relays results in corresponding counts being made and for the duration that the all vehicle relay is closed clock pulses are counted to give the percentage track occupancy. The results of the counts are printed at the end of each minute together with the time of day. Divide-by-nine-counter.-A conventional tencathode counting tube 120, Fig. 2, is arranged to divide an input pulse train by nine by injecting an extra pulse, from a mono-stable circuit 125, 126, into the input circuit every time the " 10 " cathode is reached.
