Title: Antiskid braking systems
IPC: B60T8/50
Filed: 1972-10-09
Abstract: 1350567 Antiskid braking systems; valves FIAT SpA 9 Oct 1972 [12 Oct 1971] 46425/72 Headings F2F and F2V In a vehicle antiskid braking system having two modes of response depending on whether the vehicle is on a high or low adhesion surface, a valve 24 receives pneumatic pressure exhausted from a brake 14 when a solenoid valve 16 is operated to exhaust pressure therefrom upon detection of an incipient skid by detector 20. At low pressures when the vehicle is on a low adhesion surface pressure is exhausted from brake 14 and passes to atmosphere via a port 26, grooves 34 in a shutter 36, the inwardly deflected resilient walls of shutter 36 and either a port 50 or throttle orifice 48 of a plug 46. At higher pressures above a threshold pressure, when the vehicle is braked on a high adhesion surface, a spring 42 is compressed causing shutter 36 to seat on plug 36, thereby closing port 50. The pressure in brake 14 is then progressively released as pressure firstly builds up in an accumulator chamber 30 and is then exhausted through orifice 48 past the resiliently deflected shutter walls.

Abstract: 1,143,460. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Oct., 1967 [2 Nov., 1966], No. 48472/67. Heading H4K. In a switching network formed of cascaded stages of co-ordinate matrices of relay crosspoints, the interstage links between matrices in adjacent stages each include speech wires, a setting wire and a holding wire, each crosspoint relay is in series with its own make contact between the two holding wires at that crosspoint, the junction between the relay and its made contact is connected via a diode to a setting wire and marking relays one per matrix are provided and arranged when enabled to close a make contact in each setting wire on the input side of that matrix and to connect via further make contacts, the setting and holding wire of each link on the output side. The network shown comprises three stages A, B, C each including a pair of matrices KVA1 to KVC2. Of each interstage link e.g. ZB1 only the holding wire e.g. Cbl and the setting wire ebl are shown. To establish a preselected path through say matrices KVA1, KVB2 and KVC1 the corresponding marking relays HA1, HB2 and KVC1 are enabled closing their contacts HA1 (1 to 4), HB2 (1 to 4) and HC1 (1 to 4) respectively, and a potential is applied between the ends mal and cdl of the setting wire. The selected crosspoint relays KA2, KB1 and KC3 are thus enabled via their diodes, the contacts of the enabled marking relays and the corresponding setting links eb2 and ec3. These relays close their make contacts Ka, Kb and Kc respectively. The marking potentials are then removed and these relays are maintained over the holding path between a potential of -U at E1 and earth via a contact C closed immediately after the contacts Ka, Kb and Kc. This holding potential is reverse biased relative to the selecting potential and reverse biases the diodes of the enabled crosspoint relays preventing erroneous operation during subsequent selections.

Abstract: 1,205,307. Automatic exchange systems. SIEMENS A.G. 18 Oct., 1968 [1 Dec., 1967; 26 July, 1968], No. 49397/68. Heading H4K. In a stored programme controlled exchange in which the peripheral equipments are arranged in groups each of which has its own control circuit, i.e. effectively a plurality of centrally controlled PBXs, communication between the equipments and the control circuit is effected over a common bus which starts and terminates in the control circuit and to which the equipments are selectively connectible. The ends of the bus are connected by a comparator so that information sent into the bus can be compared with information received therefrom whereby a fault signal can be generated in the event of any discrepancy. The system forms part of that described in Specifications 1,205,305, 1,205,306, 1,205,308, 1,205,309 and 1,205,301. The individual equipments JG1-JGn each contain a plurality of senders (e.g. contacts such as s1) and receivers (e.g. relays such as E1), the equipments being selectively connectible to a space or frequency division multiplex bus U11 by relays Mo1 to Mon under the control of an identifier Jd in the group control circuit AS. Serial data from a central control is stored in sender SS prior to despatch in parallel form over bus U11 to the selected equipment. The accuracy of the data after it has traversed the bus and been received back in receiver ES is determined with the aid of comparator Vg. Parallel data from an equipment is converted into serial data by receiver ES for subsequent transmission to central control and is temporarily stored in VS. When data sending from the equipment stops, the stored data in VS is sent round the bus so that the efficacy of the latter can be checked. As an alternative to comparing the whole of the transmitted data with the received data, the parity of the former data may be determined and stored for later comparison with the parity of the received data thereby reducing the duration of the connection with central control and/or reducing the amount of storage space required in the control circuit (Fig. 4, not shown).
