Brakes, arrangement and disposition of, and braking; flexible transmitters. - Equalizing connections for simultaneously operating the brakes on the four wheels of a vehicle comprise a pair of cables extending respectively between the front and rear brakes and passing over pulleys which are moved by a third cable so as to equalize the force applied to all the brakes. The front and rear brakes may also be applied independently by a second operating member. The cables 3, 4 extending between the front and rear brakes respectively, pass around pulleys on members 6, 10 which carry other pulleys about which passes the cable 14 fixed, preferably adjustably, at one end 14<1> and connected at the other end 13<1> to an operating pedal 13 or equivalent. The means for applying the front and rear brakes independently comprises cables 15, 16 connected to the members 6, 10 and to a hand lever 18 movable both forwardly and rearwardly so that the front or the rear brakes may be applied as desired. The cables 15, 16 are adjustably connected to the hand lever 18 by nuts 15<1>, 16<1>, Fig. 3, screwing on rods 15<11>, 16<11> mounted in a casing 17 pivotally mounted by trunnions at 20 and carrying the hand lever.

An oil seal for a rotary shaft 18 comprises an annular rubber body 28 having an inner face which is spaced from the shaft and terminates in a sealing edge 36, an annular zone 42 adjacent the edge 36 and formed with parallel grooves inclined to the axis and a further zone 44 formed with parallel grooves inclined at a different angle to the axis. The grooves of each zone may be of different length and cross-section, Figs. 4 and 5 (not shown), and between them form a herring- bone pattern, Fig. 3 (not shown), suitable for both directions of shaft rotation. The sealing edge 36 is urged into engagement with the shaft 18 by a garter spring 38. The oil which leaks past the edge 36 during shaft rotation is opposed by the pumping action of either one or the other of the grooved zones 42, 44, depending on the direction of rotation. In Figs. 6 and 7 (not shown), the zone (44) is equal in length to the zone (42) and a lip (60) is provided to form an annulus (63) adjacent the zone (44); at high speeds, any oil leaking past the zones is pressurized in the annulus by the rotary forces to oppose such leakage. In Figs. 8 and 9 (not shown), the oppositely-inclined grooves are formed on separate components.

Title: Apparatus for selectively distributing signals
IPC: G06F7/64
Filed: 1971-03-24
Abstract: 1392176 Data processing NATIONAL RESEARCH DEVELOPMENT CORP 26 June 1972 [24 March 1971] 7673/71 Heading G4A [Also in Division H4]  A distributer circuit comprises a number of input terminals, each connected to each of a number of logic units. Each logic unit selects one of the inputs and passes it to its one output. The selection is ordered by a combination of signals from a control unit, each logic unit having a respective control unit. The control units each store a series of combinations, providing a series of selections. The circuit may be used for interconnecting digital differential amplifiers (d.d.a.). For example, as shown, there are 64 d.d.a. 101-164, each providing a 2-bit output representing a positive, negative or zero increment. The two leads from each d.d.a. are connected to respective logic units of each of 64 pairs of logic units 301, 301<SP>1</SP>-364, 364<SP>1</SP>. Each pair of logic units is controlled by a respective control unit, e.g. 501, comprising six 8-bit recirculating shift registers. At the end of each interation clock pulses are fed to the control units to provide a sequence of eight 6-bit signals to the respective logic units. Each 6-bit signal causes the output of the corresponding d.d.a. to be passed to the output of the logic unit. Under the control of shift registers 601- 664 units 401-464 the output signals may be reversed, effectively reversing the sign with which they are passed to the d.d.a. Gates 701, 801 &c. are controlled to pass the first of the 8 signals received from the corresponding unit 401-464 to the dx decoder 901-964 and the remaining 7 signals to the dy decoder 901-964<SP>1</SP>. Each decoder provides a positive or negative increment, depending on its input.

Abstract: 614,386. Atomic piles. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, (formerly CAISSE NATIONALE DE LA RECHERCHE SCIENTIFIQUE). April 30, 1940, No. 7782. Convention date, May 2, 1934. [Class 39 (i)] In an atomic pile comprising fissile, moderating, and possibly diffusing or absorbing, substances, the chain reaction is controlled by repeatedly modifying the spatial distribution of the substances. Parts of the fissile substance may be moved relatively to one another or this substance may have recesses into and out of which moderating, absorbing or diffusing material can be moved. Rotatable discs comprising sectors of absorbing and diffusing materials, e.g. iron and water, may be partially engaged in the fissile material or pile may have side walls of diffusing material which may be moved away from and towards the pile. In a further modification an independent controllable neutron source is also employed. The control may in any case be effected by relays actuated by thermal instruments or ionization chambers responding to temperature or energy developed within the pile or by changes of specific gravity or composition of the fissile material.

Transmission lines of the " line-ground " type described in Specifications 704,050 and 708,601 are coupled to a cavity resonator. The lines comprise a " ground " conductor 2, a " line conductor 1 and a separating layer of dielectric 3 of a thickness equal to a small fraction of a quarter wavelength. The ends of the lines extend into apertures 9, 10 in the wall of a coaxial resonator 4, the " ground " conductors 2 being connected to the wall and the " line " conductors 1 extending into the cavity in the form of a probe 11 or loop 13. The apertures 9, 10 may be sealed by dielectric material 12, 14. In the form of coupling shown in Fig. 4 the " ground " conductor 2 lies parallel to the wall of a resonator 15, the resonator and the "ground" line being apertured at 16 so that the dielectric layer 3 communicates with the interior of the cavity. The size of the aperture determines the degree of coupling. Fig. 7 shows this type of coupling applied to a multi-cavity filter comprising cavities 18, 19, 20, 21 coupled in series by irises 22, 23, 24. The ground conductor 2 forms one wall of the series of cavities and is apertured at 26 and 27 to provide coupling to the first and last cavities. The " line " conductors 1 may be terminated by resistive pads in the manner described in Specification 708,589.
