Inventor: TAYLOR MARK
IPC: E04G5/14
Filed: 2008-12-30
Abstract: A clamp for securing to a scaffolding element, the clamp comprising an upper hook 3; a lower hook 7, pivotable between an open position, in which a scaffolding element may be inserted between the upper and lower hooks, and a closed position, in which the upper and lower hooks together clamp around a scaffolding element 2; and a locking element 11 movable between: a first position, in which the lower jaw 7 is held in the open position; and a second position, in which the lower jaw is held in the closed position. The locking element may be a stepped wedge which is slid into position. With sufficient shock during placement of the upper jaw 3 on a scaffolding element 2 the wedge may become dislodged and allow the lower hook 7 to pivot into the closed position due to gravity; the wedge then falls into a lower position securing the clamp in the closed position. The locking element 11 may have protruding fingers 15 which automatically move the lower hook to the open position as the wedge is moved from held closed position to the held open position. The clamp may be used for securing an advance guard rail to an upper level from the level below.

Title: Synchronising protective relay samples
Inventor: USUI MASAJI
IPC: G01R31/08
Filed: 2009-07-01
Abstract: Data from digitizing units 4a, 4b is stored in time-series buffers 11a, 11b via a data receiving circuit 5 and digitally filtrated in filters 12a, 12b. The filtered data is stored in time series in instantaneous-value stores 13a, 13b and a digital computing unit 9 sets the time of the temporally oldest data from the latest time data stored in further store circuits 14a, 14b as a reference time, extracts data having the same time as the reference time from the instantaneous-value stores 13a, 13b, and then performs a digital protection computation. The digital filters can perform phase correction using a time data monitor (fig 5,16) that applies and stores a phase correction constant based on data sampling arrival time differences. The digital filtering can also include sampling frequency correction (fig 7, 20) which ensures that only data corresponding to the lowest sampling frequency is transferred to the instantaneous value stores 13. The protective relay can be used to monitor, and operate protective relays in, an electric power system.

Title: Method for the control of electronic streams
IPC: H01J21/08
Filed: 1931-04-02
Abstract: 385,968. Discharge apparatus. HARRIES, J. H. O., Shirley, Old Road, Frinton-on-Sea. April 2, 1931, No. 10017. [Classes 39 (i) and 40 (v).] A discharge tube of the kind described in Specification 380,429 is provided with means, such as one or more control grids, having a substantial effect on the stream of electrons; or the effect may be produced magnetically or by means of one or more of the accelerating or decelerating electrodes. In the valve shown in Figs. 1, 2 and 3, two accelerating electrodes 2, 4 and a decelerating electrode 3, are mounted between a filament cathode 7 and an adjustable anode 5. The control grid 6 consists of a mesh 8, Fig. 3, and has partitions 10 forming compartments 9 in which V-shaped sections of the cathode, Fig: 2, are mounted, the partitions acting as means for focussing the electron stream. The electrodes 2, 4 consist of a wire mesh on a wire frame, and the decelerating electrode 3 consists of a wire mesh stretched across a metal plate. The wires of the meshes of adjacent electrodes are at right angles. Dimensions of the spacing of the electrodes and of the pitches of the wires of the meshes are given, for example, for producing a valve with a very low capacity between the anode and control grid. In the valve shown in Figs. 8 and 8a two anodes 5 are supported from the top of the envelope. The filament cathode 7 is arranged within the control grid 6, and the accelerating electrodes 2, 4 and decelerating electrode 3 are mounted between the control grid and the anodes. The top and sides of the plate portions of the electrode 3 are closed over so as to form a screen enclosing the elecprodes 2, 6, 7. The arrangement may be such that not more than 0.2 of the electron stream passes to the intermediate electrodes. A tubular assembly of concentric electrodes may be used in a valve of the split anode or magnetron type, and the cathode may be of the unipotential type. The valve may be used as a short-wave generator or with any of the circuits described in Specification 380,429, and a record modulator, as described in Specification 328,680, [Class 39 (i), Electric lamps, Arc &c.], may be used. In the high-frequency amplification or generating circuit shown in Fig. 10, the input circuit L<1>, C<1> is connected between a negatively-biased control grid 6 and the filament 7, the decelerating or " stopping " electrode 3 is connected with the filament, and the accelerating electrode 2 is maintained at the potential of the anode 5. The potential of the accelerating electrode 4 may be the same as that of the anode, or it may be slightly less in order to prevent loss of saturation when the instantaneous potential of the anode is less than that of the electrode 4 owing to the fall of potential across the output circuit L<2>, C2. The electrodes 2, 3, 4 may be connected together to act as a single accelerating electrode. The arrangement may be used as a generator by coupling the inductances L<1>, L<2>.

Abstract: 713,175. Boring and facing heads. WOHLHAUPTER, E., and WOHLHAUPTER, E., [trading as WOHLAUPTER & CO., E.]. May 2, 1951 [May 3, 1950], No. 10352/51. Class 83 (3) A boring or surfacing head comprises a gear 29 interposed between a slide 12 and a ring 31 for adjusting it transversely and a second adjusting ring 42 coupled with the. first by a gear for changing the direction and the speed of movement of the slide. The slide 12 can be locked in its slideway by a screw 16 co-acting: with a ball 18 and a clamping member 19. Tools aresecured in a bore 20 by screws 21. The slide 12 carries, a toothed member; 22 engaged by a worm- 23 rotated through gears 30, 29 and a worm and wormwheel 25, 26 by the graduated adjusting: ring 31. The ring 31 is clutched to the gear 30 by a ball 32 engaged by a spring ring 33 so that it may be released if over-loading occurs. When an adjustment has been made with the tool at rest; locking of the slide 12 by the screw 16 also causes a clamping pin 34 to lock the ring 31. Above the ring 31 is the second adjusting ring 42 which carries two pairs of planet-- wheels 45, 46 engaging gear teeth 312 on the ring 31 and gear-teeth on a member 35 which can be clutched' to the body 11 of the tool by a ball 36 actuated by a plunger 38 and a lever 37. The number of teeth' 312 is slightly less than the number of teeth 35. Thus, when the boring head is rotating, arresting of the ring 42 causes the slide 12 to be fed af a slow speed until a stop 49 engages a pin 51 on the fool body 11. A spring catch engaging a recess 381 in the plunger 38 is then forced out and the ball 36 is withdrawn to unlock the ring 35. When the ring 31 is subsequently arrested, the slide 12 returns at a fast rate. A hand lever 53 is provided which in one postion holds the ring 42 and in the' downward position also holds the ring 31.

Abstract: 714,642. Automatic control systems. PERMUTIT CO., Ltd. April 16, 1953 [April 25, 1952], No. 10520/52. Class 38(4) [Also in Group XXXVI] Control of the concentration of ion exchange material in suspension in a liquid is effected in accordance with the conductivity of the suspension. As shown, Fig. 2, water requiring treatment passes upwardly through ion-exchange material 10 some of the water carrying the material being drawn off via a pipe 12 to a reservoir 13 wherein the material is allowed to settle; and whence it is taken to regeneration equipment 15 and then restored to the main mass of material. Electrodes 18 are situated in the pipe 12 to enable the conductivity of the suspension, and hence the amount of material in the suspension, to be measured by a device 19, which operates via a motor 20, the rack and pinion device 21 which con. trols the depth from which the suspension is drawn off. The device 19 may instead control the rate of upward flow of the water. In another embodiment the electrodes are situated near the top of a main mass like 10 to control the upward flow so that it does not raise the level of the material to such an extent that it is washed away, e.g. into the offtake pipe in the case where the water is being treated, or into the overflow pipe in the case where the material is being backwashed. Conductivity measurements may also be used to control the degree of "fluidization" of the mass (i.e. the degree of dispersion of the material throughout the liquid) during backwashing.
