Abstract: A hydraulically-operated road breaker comprises a casing with a tool mounting and housing an oscillatory piston/striker and cylinder arrangement. A sequence valve mounted in the casing controls pressurization and exhausting of the piston to produce power and return strokes of the piston. Pilot port means positioned in the cylinder of the device are uncovered, at the end of each return stroke of the piston, to allow a valve-actuating flow of hydraulic fluid through the port means to change over the sequence valve and thereby cause stroke reversal of the piston. Manually-operable stroke selection means provide for adjustment of the position of the piston in the cylinder at which the valve-actuating flow occurs, whereby to vary the piston stroke.

Abstract: 1533559 Regenerating adsorbent beds W R GRACE & CO 27 Nov 1975 [27 Nov 1974 23 Dec 1974] 48834/75 Heading B1L [Also in Divisions C1A and H5] A bed of adsorbent, e.g. zeolite, having gas, e.g. water vapour, adsorbed thereon is regenerated by passing through the bed a direct electric current or an alternating electric current having a frequency less than 1000 Herz, at a current density low enough to preclude electrolysis of adsorbed gas, and at an energy input sufficient to achieve desorption of the gas through resistance heating. During the regeneration a purge gas or vacuum may be applied to the bed. The electrodes 1 used for bed heating may have an additional function in monitoring the level of gas adsorbed on the bed during the adsorption phase. These may be done by passing an electric current through the bed and monitoring the change in current caused by increasing conductivity as the adsorbed gas content rises. The regeneration may be started at a predetermined such current level or in response to a pre-set timer, dewpoint measurements in the outlet purge gas, bed electrical resistivity signal or regeneration energy consumption.

Abstract: A pulse generator for generating pulse groups with desired widths and relations (spacings) within and between the groups up to extremely high speeds and with a time accuracy of the order of nanoseconds e.g. in radar applications. It is purely digital and operates on a control frequency which may be derived from an internal crystal oscillator or may be externally supplied. The generator is divided into two main units, a first unit for determining the spacing of the pulse groups, and a second unit controlled by the first unit for determining the pulse widths and controlling pulse generator means. Different time space numbers and pulse widths numbers may be programmed into PROM memories of said units and may be selected by the same set of operating mode signals. The time spacing may also be optimized by means of an external computer controlling a further PROM holding information which may be combined with the time distance PROM information. Staggering and jittering radar modes may be obtained by supplying relevant mode signals. The pulse groups may comprise a ("listening interval") control pulse having a time position which falls within the next following pulse group but is generated with a fixed relation to the pulses of its own group. Further trimming possibilities with respect to the internal pulse relations of a group are available. All mode signals required are of the two-level type.

Abstract: The object is, ahead of the cooling bed in light and medium section mill trains, to cut both large round and square section bars moving at a relatively low rolling speed and U, L and T sections moving at low to high rolling speeds with a quality of cut equal to that provided by a parallel blade cut and also to cut small round, square section and flat bars, which do not require a parallel blade cut, at even higher rolling speeds, and to do this with one blade per strand. This is achieved by virtue of the fact that, with a shear which starts from the stationary condition and has crankshafts mounted in eccentric drums and a swinging linkage to keep the blades in the blade carriers parallel during cutting, the cranks of the crankshafts drivable in the eccentric drums via chain drive elements are connected to cranks of equal length, rotating in the same direction and at the same speed and bearing connecting rods, of crankshafts supported in the shear housing and engageable by means of clutches, the connection being effected by means of divisible blade carriers which are supported on the connecting rods and are seated rotatably with their blade-carrying blade heads on the first-mentioned cranks. <IMAGE>

Abstract: A lashing device for securing objects on ship's decks. The lashing device comprises a U-shaped frame member having two legs and an attachment part. Between the frame member legs extend a strap winding-on drum and a spring-biased shaft, and a holding pawl member is attached on the shaft portion that projects laterally beyond one of the frame member legs. The pawl member engages with a cogged ratchet wheel on the winding-on drum and prevents the strap from being unwound from the latter. The shaft is movable in a direction coinciding with the rotational direction of the winding-on drum. Owing to this arrangement the holding pawl member is pressed out of its engaged holding position upon actuation of said shaft, preferably effected by impact thereon by means of a ratchet wrench, and when the holding pawl is thus in its disengaged position the strap may be unwound from the drum through the action of the tension in said strap.
