Title: Improvements relating to the independent suspension of road wheels on vehicles
IPC: B60G7/00
Filed: 1964-10-28
Abstract: 1,025,839. Motor vehicle spring suspension. DAIMLER-BENZ A.G. Oct. 28, 1964 [Oct. 31, 1963], No. 44044/64. Addition to 990,613. Heading B7D. In a suspension comprising in accordance with the parent Specification, a lower triangular link constituted by an arm 23 of a transverse stabilizer bar and a strut member 22 inclined forwardly from the wheel 12, a stop member is secured to the stabilizer bar for co-operation with a projecting bead 60 provided on one end of a resilient sleeve 31 which anchors the stabilizer to the body. In this way rearward deflection of link element under lateral loads and consequent reduction in the castor angle of the outer wheel in a turn is restricted. The stop member comprises two semi-circular elements 61 secured to the stabilizer bar by a clamp 62. The elements 61 include flanges 63 which abut the bead 60, and may be made of grey east iron formed with axial fracture grooves (Fig. 3, not shown), so that ill-fitting elements will fracture on assembly and must be replaced.

Title: Interrupter units for dc power supplies
IPC: H02H3/02
Filed: 1974-10-10
Abstract: 1481458 Protecting against overcurrents SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 10 Oct 1974 [5 Nov 1973] 44046/74 Heading H2K [Also in Division H3] In a transistor switching circuit, overload current is limited to a predetermined level above the nominal rating and if the overload persists for more than a predetermined time, the load is disconnected and periodically reconnected for short periods until the overload ceases whereupon the load remains connected. Control signals at a turn on transistor Q6 which turns on transistors Q2, Q1 to connect the load 7 to the power supply +V, - V. Zener diode CR1 prevents the base of transistor Q3 falling below a preset level. Hence the emitter of Q3 and the base of Q2 cannot fall below a preset. If transistor Q1 is overloaded, the increased voltage across a low resistor R reduces the baseemitter drive of Q2 to prevent further increase in the overload current. When Q3 is limiting current, there is sufficient voltage drop across R2 to turn on transistor Q4. After a 10 Ás delay, produced by delay circuit Z Q5 conducts to keep Q6 off and hence the load disconnected. After 1 ms circuit Z has discharged sufficiently for Q5 to turn off and Q6 to reconnect the load. If the overload persists Q5 turns on again after 10 Ás but if not the load remains connected. The circuit is preferably constructed as an integrated circuit with resistor 5 a discrete external component.

IPC: H02H7/093
Filed: 1968-09-24
Abstract: 1,207,880. Motor driving arrangement; control of A.C. motors; H. KORTHAUS and R. WILKE. 24 Sept., 1968 [5 Oct., 1967], No. 45313/68. Headings H2A and H2J. An electric motor has a hollow rotor shaft in threaded engagement with an axially fixed output shaft so that when the motor is overloaded the hollow shaft moves axially against the action of springs and the frequency of current induced in a stationary coil by a stationary magnet and a corrugated iron ring fixed to the output shaft is reduced, this reduced frequency current being used to switch off the supply to the motor if the overload exceeds a predetermined value. In the three phase motor shown, a hollow rotor shaft 13 is threaded to an axially fixed output shaft 14, there being fixed to the hollow shaft a disc 32 having mounted in bores in its periphery a plurality of studs 34 surrounded by springs 26. The studs pass through holes in a plate 21 and cylinder 20, the plate 21 being axially fixed to the output shaft, and the cylinder 20 being slidable along the hollow shaft. Also fixed to the output shaft is a light metal or plastics disc 41 carrying on its periphery a corrugated iron ring 42, located adjacent a coil 48 mounted on a polepiece 43 secured to a permanent magnet 44. The output voltage of the coil is fed to a series resonant circuit II, Fig. 2, a voltage signal from which, through an amplifier, maintains conductive a thyristor Th controlling the supply to a contactor for the motor. At a predetermined minimum permissible output shaft velocity (under overload conditions) the voltage output from the resonant circuit falls below a lower limit value Vab, Fig. 3 (not shown), the thyristor is switched off and the supply to the motor is cut-off. A diode D3 ensures rapid switch off of the thyristor and the reduced speed at which the motor is switched off is adjustable by means of a variable, temperaturecompensated resistor R Th . On starting, capacitors in parallel with two resistors R 5 , R V  are charged by depressing a push-button D, and a voltage is fed through a transistor to switch on the thyristor Th. The capacitors then discharge through their respective resistors and after a delay, the voltage at the capacitors is insufficient to hold the thyristor on. The delay time is adjustable by varying the resistor R V , to permit the output shaft 14 to exceed its minimum permissible velocity so that the coil 48 can take over control of the thyristor Th.

Abstract: 1,123,819. Resilient mountings. CLEVITE CORP. 11 Oct., 1966 [10 Dec., 1965], No. 45395/66. Heading F2S. A vibration isolating-mount for connecting two members 20 having co-axially aligned openings comprises a resilient rubber like body, e.g. a ring 12, which has two diametrically opposed integral studs 14 each consisting of an outer part 18 which is narrower than an inner part 16. The mount is assembled by inserting the smaller diameter portion 18 of each stud into an opening in one of the members 20 and then pulling the portion 18 to elongate the stud until the diameter of the wider portion 16 is reduced sufficiently for it to enter the opening. Releasing the tension on the studs 14 causes them to tend to return to their original shape so that each stud is compressed within its opening with beads 22 surrounding the opening on each side. A lubricant facilitates the assembly operation which may be completed by cutting off the surplus stud parts 18. In a modification, Fig. 3, not shown, each stud (14) projects from a flat shoulder (24) which abuts against a member (20). The body 12 and the studs 14 may be made respectively of soft and hard rubber. The stud portions 16 taper gently towards the portions 18.

Title: Data structure processor
IPC: G06F12/10
Filed: 1972-10-03
Abstract: 1444228 Data processing NATIONAL RESEARCH DEVELOPMENT CORP 18 Sept 1973 [3 Oct 1972] 45494/72 Heading G4A A data processing system includes an addressable primary store and an address translator including address storage means and arranged in response to an applied address to provide an associated, translated address to the primary store, the address translator being arranged to change the association between applied and translated addresses without the transfer to the address storage means of further addresses. A sixteen word primary store 13 is addressed by four bits from register 19 via translator 14. The translator, Fig. 2a, includes four groups E-H each of two single bit registers, and operates only on the two most significant bits of the address to address one of four groups A-E of words, each group containing four words. The two most significant bits are applied to a decoder which produces one out of four outputs α 0 -α 3  to gate via gates 27-34, the contents of the corresponding group of registers to the address inputs of store 13. Further gates 35-42, and 51-66 together with two groups K, L of buffer registers are provided to exchange the contents of pairs of groups of the registers E 2 - H 3  whereby the association between an address applied to the decoder and the address supplied by the translator is changed. Further address modification is provided by exclusive-ORing, at 18, a flag bit (1 or 0) with the address in register 19 to provide a modified address which is then supplied to the translator as above. Assuming block A in store 13 is addressed with an address whose two most significant bits are 0, 0 and block B by an address 0, 1, then by exclusive-ORing a flag 1 with the second address bit an applied address 0, 0 produces an address 0, 1, and an applied address 0, 1, an address 0, 0. Thus blocks A and B are effectively interchanged. A similar modification, at 17, may be performed on the least significant address bit to effectively exchange words within a group. The arrangement is said to be of use in a data processing system providing a graphical output, e.g. on a CRT. The arrangement is also of use when processing mathematical expressions in that it enables a parameter in the expressions to be changed without necessarily requiring the whole expression to be recalculated. This is achieved using so called "plexes" which are groups of four words defining an operand or an operator. The plexes are stored in respective groups of words A-C in store 13 and the system is arranged to operate on operands stored in plexes in groups A and B in accordance with an operator in a plex stored in group C. Exemplary programs are described for calculating, for adding entries to and removing entries from a list, each plex in the list referring to the next, and using circular lists; address modification being used to effectively "move" plexes within store 13 without actually having to physically move data.
