Title: Metering systems
Inventor: EASTON HAROLD
IPC: G01D5/34
Filed: 1966-06-02
Abstract: 1,142,510. Metering systems. WARNER ELECTRIC BRAKE & CLUTCH CO. 1 Sept., 1967 [2 June, 1966], No. 24660/66. Heading G4H. A metering system includes a sensing head 12 rotated by a stepping motor 23 from a zero position until it senses the pointer 16 of the meter, the stepping motor also driving a coded disc, drum or tape. In the embodiment described in which light to a photo-cell 14 in the sensing head 12 is cut off when it senses the pointer 16 to close a gate (28, Fig. 2, not shown) passing clock pulses via a stepping motor control (24) to drive the stepping motor in one direction, the gate (28) is initially opened by a pulse from a zero sensing head 21 when the head 12 is in its zero position (a pin 17 on the head 12 then interrupts light to a second photocell 19). The coded disc or drum 34 is carried on the shaft of the stepping motor and after a short delay the pulse closing the gate (28) enables sensing members 37 to read the position of the coded member. This pulse opens a gate (29) through which clock pulses are fed to drive the stepping motor in the opposite direction until the head 12 returns to its zero position. The coded disc or drum preferably comprises binary coded conductive and non-conductive signals but it may be coded such that the output represents the 1 oz. square or a root of the input. Magnetic tape may alternatively be used.

Title: Improvements in or relating to slotted wave guide aerials
Inventor: RADFORD MATTHEW FREDERICK
IPC: H01Q13/22
Filed: 1965-06-11
Abstract: 1,145,273. Aerials. MARCONI CO. Ltd. 14 April, 1966 [11 June, 1965; 31 March, 1966], Nos. 24877/65 and 14248/66. Heading H4A. [Also in Division H1] An aerial comprises a waveguide which is so dimensioned as to propagate only the fundamental mode and which is provided with a continuous slot in one wall. The distance of the slot from an adjacent longitudinally extending boundary of the wall varies at least approximately sinusoidally along its length. As described, a rectangular waveguide G, Fig. 1, has a parallel-sided continuous slot S in one broad wall B which follows a sinusoidal path whose axis is parallel to the edge of that wall. The width of the slot may be from #g/50 to #g/10, a preferred value being #g/20, where #g = length of the wave in the guide. When the pitch L of the slot equals #g the main direction of radiation is broadside, and this direction may be changed by using another frequency. It is stated that the bandwidth obtained is about 30%. In a second embodiment the sinusoidal shape of the slot is approximated by straight segments (Fig. 2, not shown) and in a third embodiment a ridged waveguide is used (Fig. 3, not shown). The cross-section of the waveguide may be other than rectangular, for example, flattened elliptical, provided there is a flat wall for the slot. In other embodiments, the waveguide is bent into a generally sinusoidal shape, and the slot is straight (Figs. 5, 6, not shown). An array may comprise a number of such waveguides placed side by side with their broad walls, containing the slots, coplanar. Or a number of such waveguides may be arranged on edge side by side, with their slots feeding an array of horns or flares H1, H2, H3, Fig. 4, through sideways extending waveguides F1, F2, F3. Coupling cavities C1, C2, C3 are provided between the sinusoidal radiating slots of waveguides of the kind shown, for example, in Fig. 1 and the waveguides Fl, F2, F3, but they are not required if the radiating slots of the waveguides are straight.

Title: Improvements relating to swell louvre actions for organs
IPC: G10B3/16
Filed: 1933-09-08
Abstract: 428,448. Organ swell actions. WILLIS, H., and ALLEN, A. THOMPSON-, 234, Ferndale Road, Brixton, London. Sept. 8, 1933, No. 24953. [Class 88 (ii)] In a wind motor, for controlling the movements of swell louvres in organs and to which wind is admitted through different valve orifices so as to control the rate of movement of the motor board, means are provided for opening the said orifices in succession cumulatively. The motor board 11 of the wind motor 10 has a rod 15 connected to a pivoted lever 19 carrying a rod 19, operating the louvres. The motor has chambers 12, 14, each with a group of orifices 21 or 22 for admission of wind, the orifices in each group being of varying crosssectional area, and each having a separate controlling valve 23. An exhaust valve 47 fitted to each chamber 12, 14, carries a diaphragm 48 and is urged towards closing position by a spring 49, and a chamber 51 behind the valve may be opened to wind or atmosspheric pressure by the movement of a valve in a pipe 50 connected to the chamber 51. A contact bar 39, Fig. 3, connected to a foot pedal 41, is urged by springs 44, 45, to a position midway between two series of contacts 36, 37, which operate the valves 23 associated with the ori - fices 21, 22, respectively. Each contact 36, 37, is adjustable by a screw 46. When the pedal 41 is moved in one direction the bar 39 engages one or more of the contacts 36 to energize an electro-magnetic device 35a, Fig. 2, which closes a valve 34 and opens a valve 35 to expose the back of a valve 23 to atmosphere through a duct 32. Wind pressure acting on the diaphragm 26 of the valve 23 causes the latter to open and allow wind to pass from a chest 24 through the orifices 21. At the same time the valves in the pipes 50 are operated electrically, that associated with the chamber 12 moves to supply wind to its chamber 51 and close the corresponding valve 47, and that of the chamber 14 moves to open its chamber 51 to atmosphere and open the corresponding valve 47. The motor board 11 is thus moved, the speed of movement being proportional to the number of orifices 21 open. To move the motor board 11 in the opposite direction the pedal 41 is moved so that the bar 39 engages one or more of the contacts 37 to open the corresponding orifices 22, wind being exhausted from the chamber 12 simultaneously. To hold the louvres firmly in the closed position, the link 19 at the end of its travel closes contacts 55, 56, Fig. 1, and wind is admitted to the chamber 14 through an orifice 54. The valve controlling the orifice 54 is closed when wind is admitted through an orifice 21 by the opening of a switch in the same circuit as the contacts 55, 56. This switch is opened by a motor 57 when wind is admitted to the chamber 51 of the exhaust valve of the chamber 12.

Abstract: 808,588. Removing bark from logs. CUNDEY, J. E., and CUNDEY, W. B. Nov. 11, 1957 [Aug. 16, 1956], No. 25029/56. Addition to 778,477. Class 145. The log-barking machine of the parent Specification in which logs are fed forward against the convex face of a rotary cutter disc 8 by a feed roller 14, is provided with means for raising or lowering the roller relative to the disc to suit various diameters of log. The shaft 13 is connected by a universal coupling 12 to the worm drive 11 and at its other end is carried in a bearing 18 on a swivel bracket 19 which can be raised and lowered by a lever 20, shaft 21 and handle 22. In the lowered position, the handle 22 rests on a stop bracket 23 and in partly or wholly raised positions is retained by a pawl 24 and rack 25. The roller 14 is a toothed wheel, instead of the wide vaned wheel of the parent Specification, and it is connected to the shaft 13 through a clutch 17 to prevent damage if the wheel jams. In the raised positions of the wheel, the angle of the helical path in which it engages the log is increased and so logs of smaller diameter are fed forward more quickly than in the lowered positions suitable for larger logs requiring a slow feed on account of the larger area to be de-barked. Reference is made to raising the wheel bodily either horizontally or vertically or inclinedly.
