Title: Improvements in core shuttering suitable for moulding hollow walls
IPC: E04G15/06
Filed: 1945-06-08
Abstract: 616,697. Casting concrete; cores. RUMBLE, R. W. June 8, 1945, Nos. 14529 and 14530. Convention dates, June 8, 1944, and April 7, 1945. [Class 20(ii)] Collapsable core shuttering for casting hollow walls comprises a body portion 2 formed from parallel plates 5a, 5b and edge portions formed from flexible spring U- shaped members 24, the limbs 26 of which frictionally engage the outer faces of the plates 5a, 5b. The plates 5a, 5b are reinforced by staggered, interengaging corrugated sheets 8, and vertical edge portions 10 of box section. The body is closed at top and bottom by angle-members, the horizontal flanges 11a, 11b of which are bent back on themselves to form freely interengaging tongues and grooves. The angle-members project above the body at the top and are spaced slightly inside the body at the bottom to form a spigot and socket to enable a number of bodies to be joined lengthwise. The plates 5a, 5b are moved apart to expand and allowed to approach each other to collapse, the core, by the vertical movement of bars 16, having a number of cut-away tapered portions engaging bolts 19 in the edge portions 10 of the plates. The bars 16 of successive body portions are connected together. The limbs 26 of the edge portions 24 are forced apart as the body portion 2 is expanded and spring towards each other as the bars 16 are raised to allow the core to collapse. In a modification, the edge portions 24 are secured to the body and are drawn inwards towards the body portion as the bars 16 are raised by lugs 39 or the bars 16 having inclined surfaces 48 to engage projecting lugs 38 on the edge portions 24. When the core is expanded, the edge portions are projected outwards by inclined spring strips 43 which engage the lugs 38 but yield if the edge portions engage an obstruction. After collapsing the core further upward, pull on the bars 16 will remove it from the moulded cavity, the bolts 19 engaging ledges 21 on the bars 16. The edge members may be coterminous with the body portions 2 or may extend over several body portions, as shown. A continuous cavity may be moulded by closing the gaps between adjacent cores with thin metal sheets, and a single core may be increased in width by adding additional edge portions, the limbs of each of which clasp the preceding edge portion between them. Specification 616,527, which describes the tie bars 51 which may be used to hold cores in position inside wall shuttering 49, is referred to.

Patent GB-1189047-A (GB)
Title: Improvements in or relating to Soil Cultivating Implements
IPC: A01B33/06
Filed: 1968-03-26
Abstract: 1,189,047. Tined harrows. C. VAN DER LELY N.V. 26 March, 1968 [30 March, 1967], No. 14571/68. Heading A1B. A harrow comprises a frame 1 movable over the ground when attached to a tractor, with at least two tined members arranged to be driven by the power-takeoff shaft of the tractor in which at least one tined member 2 has a grating 16 or plate-like member 36 attached to it so that, during driving of the implement, the latter member moves in contact with the ground. This member helps to level or crumble the ground. Several circular tined members may be provided, each rotatable about a vertical axis and with the levelling or crumbling member 13A consisting of radial rods 16 as in Fig. 3 attached to a plate 13. The plate is supported by a shaft 12 and stop-washer 12A on a spring 12B acting against a stationary washer. This arrangement allows the member to be deflected vertically by any undulations of the ground surface. Tines 10 extend down vertically from a plate 9 which is rotatable with the shaft 12 about the axis of the member 2. Screens (32), see Fig. 1 (not shown) attached to the main tool bar 1 may be provided between the tined members, such that the rear edges of the screen are located approximately in the vertical plane containing the axes of rotation of the tined member. These screens prevent the soil from being deflected sideways to any great extent. Also, there may be two plates (29), extending back from either end of the row of tined members 2 on the main tool bar 1, carrying a smoothing strip (31A). Rotation of the members may be effected via bevel pinion 16A, sprocket wheels 21 and endless transmission chains 22, the whole being driven from a power source on the tractor via transmission means which may be adjusted to produce at least two speeds of rotation for a constant driving speed. The element 2 may be caused to rotate in a common direction, or they may be arranged in pairs to rotate in opposite directions. An alternative construction of the member 2 is shown in Fig. 5 in which the tines 10 are arranged to lie at an angle to the vertical, and the crumbling or levelling member 36 is of solid construction with upwardly sloping edges and slots 37 to accommodate the tines. In a modification shown in Fig. 10 one or two long supporting members 65 carry a row of tines 66 orientated at right angles to the direction of travel of the tractor. The crumbling or levelling member 67 is a long solid strip of curved cross-section. The members 65 are supported at their ends on the edge of substantially horizontal discs 62 which are attached to rotatable shafts in connection to the tractor power source via bevel pinions. Rotation of the discs 62 causes each tine 66 to execute a circular path through the soil. The power transmission elements may be arranged so that the two tine supports 65 move alternately toward and away from each other, or maintain a substantially constant distance apart.

Title: Electronic masking method and apparatus for electrical colour reproduction systems
IPC: G03F3/08
Filed: 1952-06-11
Abstract: 712,558. Copying in colour by scanning. TIME, Inc. June 11, 1952 [June 12, 1951], No. 14747/52. Class 40 (3) in a colour reproducing system in which a number of channels carry a sequence of signals representative of the colour values of the original and masking corrections are employed, the signals in one of the channels are masked by a function of the instantaneous maximum signal voltage derived from the signals in all the channels. In the arrangement shown in Fig. 1 with channels 10, 10', 10" carrying signals corresponding to the yellow, magenta and cyan components of the original, the signals of the cyan channel 10<SP>11</SP> are masked by the maximum signal voltages, the magenta channel is masked conjointly by the signals of the magenta and cyan channels and the yellow signals are masked by the signals in the magenta channel. Portions of the output of preamplifiers 12, 12', 12" are fed via rectifiers and filter networks 25, 25<SP>1</SP>, 25" to the grids of triodes 28, 28', 28" whose cathodes 30, 30', 30" are connected in parallel to earth via a resistor 32. The voltage appearing across this resistor will be the instantaneous maximum resulting from the signals applied to the valves 28 ... and is applied to the grid of a valve 36" whose anode is connected to a modulator 18" which is of the thyrite type, and as described in U.S.A. Specification 2,580,692. The modulator 18' is fed from the valve 36' to whose grid voltages are applied simultaneously from the outputs of the rectifiers 25', 25" of the magenta and cyan channels, whilst the valve 36 associated with the modulator 18 is controlled by the rectifier 25' of the magenta channel. In a modification, Fig. 2 (not shown), the masking of the magenta signals is controlled by the yellow and cyan signals, a unilateral conducting device, e.g. a diode, being included in the connection from the yellow channel network to prevent reduction of the masking voltage in the cyan channel when this latter voltage is greater than the yellow masking voltage. In a further arrangement, Fig. 3, the magenta channel is masked by the cyan signals except in generally yellow areas where reduced masking of the magenta is provided so that in effect less magenta appears in the predominantly yellow areas. The grid 35' of the valve 36' controlling the modulator 18' in the magenta channel is connected to the output of the cyan channel network 25" and to the anode 50a of a valve 50 having four grids and the cathode connected in parallel to the output of the yellow network 25, and a fifth grid connected to the output of the magenta network 25'. The tube 50 is non- conducting except when the voltage derived from the yellow channel is low relative to that from the magenta and cyan channels 10<SP>1</SP>, 10". When the valve 50 conducts the potential applied to the grid 35' of the valve 36' is reduced, and the output of the modulator 18' is increased so that, since the output signals are used to produce colour negatives, less magenta will appear in the yellow areas.
