Title: Method for shortening messages in receivers of centralized multi-service vontrol systems
IPC: H04L13/18
Filed: 1973-09-26
Abstract: 1392426 Remote control BROWN BOVERI & CIE AG 26 Sept 1973 [19 May 1973] 45107/73 Heading G4H  In a method of shortening or condensing messages in receivers of centralized multiservice control systems by remote control, a receiver is reset to its off position when a reset pulse transmitted by a central station during a pulse interval coincides with a scanning pulse produced in the receiver. The central station sends a start pulse followed by a series of message pulses, the start pulse causing the generation, in the receiver, of a reference series of message pulses ("scanning pulses") which is compared with the transmitted series to perform a control action or equality. The central station may interpolate a reset pulse between any two of the message pulses (or lengthen one of the latter) and coincidence of this with any of a series of interpolated pulses in the reference series causes reset.

Gates N0-N4 are provided to produce a carry from the group in a faster time than the carry produced from ADD 4. Each adder has an equivalence output a#b(ab+ab) and a disjunction output a+b. The equivalence outputs of all adders are fed to gate N0, the disjunction outputs of each adder ADD 1 to 4 are fed to a corresponding gate N1 to N4 and the gates receive the equivalence outputs of all adders of higher significance than their corresponding adder. The outputs of the gates are connected together to form an inverted carry to the next group. It is stated that the gates may be NOR gates or NAND gates and the adders ADD 1, ADD 2 using NOR gates are illustrated in Fig. 2, not shown.

Title: Device for indicating the elements of a lattice
Inventor: COCHINAL ROLAND
IPC: G21C17/04
Filed: 1961-12-28
Abstract: 944,453. Indicators; reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 28, 1961 [Dec. 30, 1960], No. 46421/61. Headings G4H and G6C. An indicator comprises six transparent discs 1 Fig. 2 which may be independently rotated about a common axis by a motor which drives a selected disc through a clutch associated with that disc. Each disc carries numbers corresponding to the identities of fuel elements in a nuclear reactor, a plurality of such numbers being visible through an aperture 19 in a mask. Detection of a faulty fuel element causes the appropriate disc 1 to be rotated until the number corresponding to the faulty element is behind window 19, identification of the element being completed by lighting the appropriate lamp 20. The discs 1 are normally in a position in which a blank segment lies behind window 19. In the embodiment described provision is made for displaying one of 2304 elements distributed into twelve groups GIGXII each containing twenty-four clusters F 1 -F 24  of eight elements each. Thus an element is identified by an expression such as GII, F 11 , 7. Each disc 1 is divided into 25 segments, one of which is blank, and the remaining 24 are allocated to the 24 clusters of an odd and even-numbered group, one cluster of each group to each segment. Eight radial positions in each half segment are allocated to the element number in the cluster, and the innermost, ninth radial position is used for indicating the group and cluster associated with that half segment. An element is thus identified by lighting the appropriate one of the eight outer lamps 20 in the corresponding half segment together with the inside lamp of the same row. Leads F<SP>1</SP>, GIF<SP>1</SP> 1 , GXII to F<SP>1</SP> 24  GI-F<SP>1</SP> 24  GXII Fig. 3 identify the clusters, one of these being marked to set the appropriate cluster register M 1 -M 24 . Leads G<SP>1</SP>I to G<SP>1</SP>XII identify the groups, one being marked to set the appropriate group register E 1 -E 6 . Leads G<SP>1</SP>I to G<SP>1</SP>XII are also gated together as shown in Fig. 4 to decide whether the group number is even or odd and to energize the corresponding row of lamps 20. The group register E 1 -E 6  which is set energizes the clutch of the corresponding disc 1, and as the disc is rotated the associated micro switch 18a is actuated to supply pulses to counting circuit A 1 -A 24 , A 0  which then applies a-reset signal to registers M 1 -M 24  in turn until the position corresponding to the set cluster register is reached, whereupon the supply to motor 11 is interrupted. The marked lead C 1 <SP>1</SP>-C 8 <SP>1</SP> energizes the appropriate lamp 20 to complete the display. A reset signal on lead S 1 <SP>11</SP> causes motor 11 to drive the "offnormal" disc 1 until stage A 0  is energized, whereupon circuit R and the set register E 1 -E 6  are reset.

Abstract: 1,060,660. Motor vehicle driving gear; preventing pitching. ROLLS-ROYCE Ltd. Nov. 26, 1963, No. 46747/63. Headings B7D and B7H. In a motor vehicle with inboard drum or disc brakes 42, 43, and at least one pair of final drive gear-boxes 40, 41 each of which transmits the drive from an engine 11 to one road wheel, a pair of links 70, 71 connects each gear-box to the vehicle frame and when the respective gear-box is subjected to a drive or braking torque applies a resultant force to the vehicle frame to counteract the effect of weight transfer due to said torque and to counteract pitching of the vehicle frame. The gear-boxes 40, 41 are driven through parallel propeller shafts 34, 35 and the wheels 52, 53 may be driven through gear-boxes 50, 51 and parallel propeller shafts 44, 45. Driving gear.-The main gear-box 16 may be separate from the engine 11 and the differential 15 preferably drives the oppositely-rotating propeller shafts on each side of the vehicle through spur or worm gearing to provide low propeller shaft axes. In the latter case the differential is preferably arranged below the front seats of the vehicle (Fig. 4, not shown). Further differentials which drive the propeller shafts on each side of the vehicle may divide the torque between the front and rear wheels unequally. These differentials and differential 15 may be of the limited slip type. Preventing pitching.-The gear-box 40, Fig. 2, is pivotally connected to the vehicle frame by a downwardly extending front link 71 and an upwardly extending rear link 70 the ends of the links being resiliently mounted. Drive haft 36 is mounted for rotation only in the ear casing. On braking, for example, the brake torque produces compression loads in the links, the reactions of which on the gear casing, due to the different distances of the links from the vehicle longitudinal axis, tend to rotate the drive shaft 36 clockwise as shown in Fig. 2 and thus counter " nose dip " due to vehicle weight transfer. The propeller shaft directions of rotation may be chosen so that drive torque on the gear casings acts analogously to control pitching on acceleration. In an alternative arrangement (Fig. 5, not shown) the gear-box (84) is supported by an upper link (86) pivoted to the vehicle frame and a lower link pivoted to a lever (92) with its outer end pivoted to hub carrier (95) and its inner end (94) pivotally connected to the frame either directly or through a short link. In this case the links (86), (91) may be equidistant from the vehicle centreline.
