IPC: C07C43/313
Filed: 1979-08-23
Abstract: The invention provides new imidazole derivatives of the general formula:-   <IMAGE> wherein R<1> represents a methyl or ethyl group, R<2>, R<3> and R<4>, which may be the same or different, each represent a hydrogen or halogen atom or an alkyl or alkoxy group which may optionally be substituted by one or more fluorine atoms, and R<2>, R<3> and R<4> do not all represent hydrogen atoms, which possess useful herbicidal properties.
Patent GB-2035025-A (GB)
Title: Trailed agricultural implement
IPC: A01B63/22
Filed: 1979-11-26
Abstract: The rear end of the oblique frame of a multi-share plough is supported by a land wheel 48 and a rear furrow wheel 36 on leading and trailing pivoted arms 40 and 30 respectively. The wheels are lowered and raised together, to raise and lower the frame respectively, by a double-acting hydraulic cylinder 66 which rocks an arm 62 clockwise to raise the wheels. The arm 62 then pushes an arm 58 clockwise, the arm 58 being integral with the land wheel arm 40, and pulls the arm 30 anticlockwise by a link 78. When the cylinder rocks the arm 62 anticlockwise the wheel 48 rises faster than the wheel 36 (because of different lever arm ratios) until the arm 40 hits a stop 92, this being the illustrated position. This tilts the beam carrying the arms 30 and 40 and rolls the frame in the sense tilting the share points 22 into the ground. Lost motion between the arms 62 and 58 allows the wheel 36 to finish rising so digging the shares into working depth while levelling off the tilt which has helped them to dig in efficiently. <IMAGE>

Title: Cylinder Head for Compression- ignition Internal Combustion Engines having Precombustion Chambers
IPC: F02F1/24
Filed: 1980-01-08
Abstract: An aluminium cylinder head (1) is formed with a cooling chamber (9) and a number of cavities which provide for each cylinder (4) of the engine a precombustion chamber (5) in communication at its upper end with a seat (6) for a fuel injector.

Patent GB-2068658-A (GB)
Title: Improvements in or relating to electrical power control
IPC: G05B11/28
Filed: 1980-01-17
Abstract: A circuit for controlling the power applied to a load in proportion to the value of a parameter comprising a sensor for sensing the parameter to produce an electrical signal indicative of the value of said parameter. The sensor output is combined with an alternating signal from a generator 12, and an oscillator 14 generates pulses at a rate which depends upon the magnitude of the combined signal. The output of the oscillator 14 is used to switch a triac 17 on and off and thereby control the power applied to the load 18. A variable resistor 33 connected to the oscillator 14 can be used to control the range over which the power can be adjusted. <IMAGE>

Title: Positioning devices for patients
IPC: A61B6/00
Filed: 1980-01-26
Abstract: It has been suggested that it is very important to position patients reproducibly at different stages of radiotherapy treatment planning and treatment, or similar procedures. Devices have been described for positioning a patient's upper and lower thorax. This invention provides reproducible positioning for a female patient's breasts, for example in planning treatment of and treating breast tumours (4). The patient (1) is placed prone, using for example an upper thorax device (14). A support device (8) is placed central to and beneath her breasts to partially displace them outwards. The device may be triangular in section with one apex 9 contacting the chest wall at the sternum. Restraining straps (11) may be provided to hold the breasts against the support device. Means (15) may be provided to take a healthy breast (at 16) from the path (13) of radiation through the tumour (4). <IMAGE>
Patent GB-2049849-A (GB)
Title: Anti-locking Mechanism
IPC: B60T8/58
Filed: 1980-04-03
Abstract: An anti-locking means includes an assembly 70 attached to move with a wheel 82 of a vehicle. The assembly 70 includes a spring biased inertia wheel 106 movably mounted to a manifold 94. A valve 116 connected to control the application of braking pressure is normally held closed (e.g. blocking opening 126) when the inertia wheel 106 and manifold 94 are rotated at the same rate by the wheel 82. When the vehicle wheel is decelerated at an excessive rate, the inertia wheel overcomes the bias of the spring and continues to rotate about the manifold to open the valve (by uncovering opening 126) and prevent braking pressure from being applied to the wheel. Opening 126 is formed in a line pressurising an actuator which, on release of pressure in the line when the hole is uncovered, prevents fluid passing through a valve in a line from a master cylinder to a brake actuator. Stops 136, 138 are provided to prevent excess relative rotation of the inertia wheel 106. <IMAGE>

Title: Shuttlecocks
IPC: A63B67/18
Filed: 1980-04-25
Abstract: The invention relates to moulded plastics shuttlecocks and aims to provide a moulded shuttlecock that resembles a Feather shuttlecock in appearance and simulates feather shuttlecock flight properties more closely than conventional moulded shuttlecocks. The visible effect is achieved by moulding a skirt structure having a diverging array of stems (5) and a vane area (4) at the outer part of the skirt, the vane area being a series of half leaves (7) and part half leaves (8), one attached on either side of each stem, the leaves being shaped to appear as overlapping feathers but without any actual overlap occurring. The desired flight properties are achieved by separating each half leaf and its associated part half leaf along part of the boundary line (10) where they would otherwise appear to overlap and forming these separated portions in different planes. <IMAGE>

Patent GB-2091501-A (GB)
Title: 2-Wire Sensor Circuit
IPC: H03K17/725
Filed: 1981-11-05
Abstract: A sensor element O changes its oscillation amplitude when a piece of metal is close, so turning on transistor QA. This fires thyristor T via firing circuit Z, and increases the load current drawn from a rectifying circuit RB1.The AC load current into RB1 therefore rises, and the voltage across resistor RG rises to fire triac SCR1. This raises the load current through load RS, so indicating that the piece of metal is near. The thyristor T therefore switches only a relatively low current, and its recovery is therefore facilitated, while the triac SCR1 carries the high current required to operate the load RS. <IMAGE>

Patent GB-2127848-A (GB)
Title: Electrophoretic slip casting
Inventor: LUCEK JOHN WILLIAM
IPC: C25D1/14
Filed: 1982-09-29
Abstract: The slip is cast into an electrophoretic mold set-up including a depository 25 and non-depository 28 electrode, wherein the depository electrode makes up less than the entire surface area of the shape- defining element 26 of the mold set- up. Gas formation at the depository electrode is thereby reduced so that porous surfaces in the casting are eliminated or localized. In addition the deleterious interaction of slip hydrolysis and electrode corrosion products is reduced or confined, particularly if the voltage is initially low and later increased. In the fabrication of a U-shaped channel piece 27, the non-depository electrode 28 may be moved from one end of the mold set-up to the other incrementally during casting (fig. 5). In the fabrication of a tube (fig. 6, not shown) a series of electrodes 35 to 42 are contained within the wall of the mold and adjacent pairs of electrodes (forming the anode and cathode respectively) are activated sequentially so that the casting is formed first at the bottom and finally at the top. The casting slip comprises a liquid vehicle, on inorganic powder and, optionally, a deflocculant and has a viscosity of 0.5 to 100,000 centipoises. <IMAGE>
