Patent GB-2138389-A (GB)
Title: Apparatus for transporting and unrolling cylindrical bales
Inventor: HOTHAM GRAEME
IPC: A01D87/12
Filed: 1983-03-08
Abstract: A pair of parallel spaced box girders 2 are secured to the rear of a tractor. An arm 8 is pivotally mounted between the box girders 2 about a vertical pivot pin 9. In the position shown, a stay bar 20 holds the arm 8 extending rearwardly, the arm 8 being movable to that position by a hydraulic jack 17. A central spike 11 axially engages the cylindrical bale 24, and a number of other spikes 16, extending parallel with the central spike, engage and grip the inner portion of the bale. The spikes 16 are mounted on a flange including a tyre 15 on its outer rim, the flange itself being mounted on the central spike 11 which is rotatably mounted on the arm 8. The bale is lowered into contact with the ground and the tractor is moved forwards to leave a flat wad or swathe 23 on the ground. When the diameter of the bale is sufficiently reduced the tyre 15 contacts the ground to continue to impart rotational movement to the bale. In order to pick up a fresh bale, the stay bar 20 is detached from the position shown, and the hydraulic jack 17 withdraws the arm 8 until it lies between the girders 2. The tractor can then be reversed to drive the spikes into a new bale. <IMAGE>

Title: Microwave oven with rotary antennas
Inventor: YOSHIMURA HIROFUMI
IPC: H05B6/72
Filed: 1983-03-11
Abstract: A microwave oven has a rotary antenna (16) for feeding electromagnetic waves from a waveguide (13) to a heating chamber, the antenna comprising a first antenna portion (17) and a second antenna portion (18) which extend in mutually opposite directions and substantially at right angles to a rotary shaft of the antenna. The first antenna portion (17) is longer than the second antenna portion (18) by approximately one quarter of the wavelength of the electromagentic waves used, and the free end of the first antenna portion (17) is bent substantially at right angles over a length not exceeding one quarter of the wavelength so as to ensure a uniform electric field distribution within the heating chamber. In addition, a dielectric seal plate (22) supports the antenna shaft and has a tapered portion (22a) projecting into the waveguide (13) to prevent a sharp change of impedance in the waveguide, whereby spark discharge due to a high-frequency electric field is effectively prevented even in the absence of a heating load in the heating chamber. <IMAGE>

Patent GB-2146474-A (GB)
Title: Test arrangement
Inventor: BROWN GEORGE
IPC: G09G3/20
Filed: 1983-09-14
Abstract: A test arrangement permits a scene correlator to be tested under similated conditions. If a scene correlator, which is operative in a linear imaging mode, is mounted on board an aircraft it is very difficult to test even in expensive and time consuming flight trials. The test arrangement uses a linear array 31 of light emitting diodes which are selectively and repetitively energised to artificially create a predetermined two-dimensional field of view for an image sensor forming part of the scene correlator. Data representing typical flight parameters are stored in 23-28 and used to modify the scene or the field of view created. The data fed to the linear array may simply turn the diodes on or off or be amplitude coded to control the level of brightness. <IMAGE>

Title: Door locking mechanism
Inventor: TINDALL MELVYN ALAN
IPC: E05B63/20
Filed: 1983-11-07
Abstract: When door 10 is closed, a button 34 on the leading edge 11 is depressed, e.g. by abutment against a door jamb 49 or against another door or other solid object so that sliders 31, 32 are held together and a spring-biassed bolt 13 can move through slots 44 in said sliders 31, 32 to automatically lock the door 10. When door 10 is opened by bolt release means of any known type (not shown), release of the button 34 allows the sliders to be pushed apart, e.g. by leaf spring 40, so that the bolt 13 is firmly engaged by slots 44 and held in its release position. Serrations on the bolt may assist secure engagement. A mechanism having a catch release button on the leading edge of the door is suitable for fitment to doors which open only in one direction, doors which open in both direction and sliding doors. The mechanism is described in the context of emergency exit doors and has two sliding bolts. <IMAGE>

Title: Golf trainer
Inventor: TSUTSUMI TAKAO
IPC: A63B69/36
Filed: 1984-03-29
Abstract: The trainer has a set of magnetic sensors 6a-d which generate outputs when a golf club passes the sensors, two of the sensors being spaced by a given interval, and a set of zero-crossing detectors which detect zero-crossings points of the sensor outputs and produce a pulse signal at each zero-crossing point, the period of time that it takes for the club to swing through the given interval being measured by counting clock pulses between two of the pulse signals. The trainer includes a switch 29 which is used to select a particular club. For each swing, the velocity of the selected club head is calculated from the measured time period and the velocity is used to calculate the carry for the selected head. The velocity and carry are stored in a memory and displayed on a display 2. The sensors are buried in a case 12 which may be removably installed in a base mat 3 and which may have fork-like protrusions carrying the sensors. <IMAGE>

Filed: 1984-11-01
Abstract: Sensitive electrical material, e. g. lithium metal electrode material, protected by non-porous fluidimpermeable flexible material whose compositio can be altered, e. g. by solvent extraction of a salt or polymer therefrom, to render the protective material fluid-permeable. When the material is used as a cell electrode, the protective material composition is preferably altered on contact with liquid electrolyte in the cell, thereby converting the protective material into an electrode separator. The sensitive material can be processed, e. g. rolled into thin strips while protected by the non-porous protective material.

Title: Optical state-of-polarisation modulator
Inventor: EPWORTH RICHARD EDWARD
IPC: G02F1/01
Filed: 1985-12-13
Abstract: An optical measurement system includes a polarisation modulator having an element which is controlled to sweep the output polarisation state such that the time integral of the system photodetector output becomes independent of polarisation. It is shown that, on the Poincaré sphere, the output polarisation states must have a time-weighted distribution symmetrical about the sphere centre; in particular, the output state must sweep around a great circle at a uniform rate. The modulator may require to be preceded by an adjuster to bring the input polarisation state on to a given great circle. Embodiments with optical fibre 15 may use stress-induced linear birefringence 30, coupled if necessary with physical rotation (Figs. 5,6) or rotating stress (Fig. 7); magnetically-induced circular birefringence (Faraday effect) may alternatively be used (Fig. 8). The drive waveforms are triangular. The adjuster comprises two quarter-wave linearly-birefringent loops 29 of adjustable position. The system is a reflectometer using heterodyning of backscattered light (Fig. 1). <IMAGE>
