IPC: E04G21/18
Filed: 1984-01-06
Abstract: A staff 1 for use in construction of a wall comprises a base member 3 and an upright 4 extending from the base member 3. The upright 4 is pivotally mounted by means of a ball joint 5 to the base member 3 to allow universal adjustment of the angle of inclination between the upright 4 and the base member 3. Two bracing members 6 extend between the upright 4 and base member 3 and each is fixed to the upright at their upper ends and attached to the base 3 at their lower ends 8 through a locating bolt 9 received on a locating slot 10 in a support arm 11. The support arm 11 is hingedly mounted by hinges 12 to the base member 3 to facilitate movement of the bracing members 6 relative the base member 3 to accommodate angular adjustment of the upright 4. The upright 4 may be moved upwards and downwards by a screwjack. A plurality of transverse holes 25 spaced around the upright 4 are provided for a levelling string for levelling each course during construction of a wall. A spirit level tube 20 is provided in the upright 4 for plumbing the staff. An adjustable toggle clamp clamps the upright 4 to the base member 3 in any desired position. In an alternative construction the bracing members are split intermediate their ends to define a pair of bracing portions interconnected by a turnbuckle. <IMAGE>

Title: Improvements in brake force distribution
Inventor: KLEIN HANS-CHRISTOF
IPC: B60T8/72
Filed: 1984-02-10
Abstract: With a view to controlling the distribution of brake force onto the front and rear axles of an automotive vehicle in response to the momentarily prevailing static and dynamic axle load distribution, the wheel rotational behaviour (???) on the front axle (VA) and on the rear axle (HA) and the translational deceleration (-b) of the vehicle or variables proportional to said measured values are determined by way of sensors (8, 9, 10). After the said signals having been electronically processed and combined at (7), the share of the brake pressure (PHA) fed to the rear axle in response to the front wheel brake pressure (PVA) is so controlled by means of solenoid valves (4, 5) that the brake slip at the rear axle (HA) corresponds to the brake slip at the front axle (VA) or is slightly less than the front wheel brake pressure. In the event that nonetheless a locking tendency of the rear wheels occurs, e.g. as a result of rapidly changing road conditions, the brake pressure at the rear axle is reduced with the aid of another quick-acting electromagnetically operated valve (6) and is maintained constant at the low value until the front wheel pressure has decreased. If either circuit (2, 3) fails, sensor 18 actuates control 7 to permanently open valves 4, 5 and close valve 6. The circuits need not be diagonally split (Fig. 3 not shown). <IMAGE>

Each plate is provided with a recess having a venting aperture in the recess. The recess extends outwardly from the rear of the plate and the venting aperture is located at the deepest portion of the recess. The plates are preferably formed as an integral unit. Each trough has a pair of conduits 50, 51 extending into the cells to permit venting of the battery. The battery cover has upper and lower top surfaces with the troughs defined in the upper top surface and battery filling holes located in the lower top surface. Conveniently such a construction ensures the battery filling holes are located close to a line indicating the maximum electrolyte level in the battery, and provides a battery in which leakage and spillage is substantially eliminated. <IMAGE>

Inventor: AMPFERER HERBERT
IPC: F02M31/10
Filed: 1985-02-11
Abstract: When the engine is below its operating temperature the induction manifold 3 is heated by part of the liquid by-passing the cooler 5 of the main engine cooling circuit 7.

Title: Production of complex metal hydroxide powders
Inventor: KINGON ANGUS IAN
IPC: C01G25/02
Filed: 1985-12-09
Abstract: The invention provides a method for the production of complex metal hydroxide and/or hydrous oxide particles, such as those of titanium and zirconium, useful for obtaining the oxide powders thereof, for use in ceramics. The production of spherical monosized particles is promoted and the method involves mixing a solution (12) of an alkoxide of the metal in question in a solvent such as an alcohol with a solution (14) of water in a similar solvent under turbulent conditions (16), quickly to form a homogeneous mixture to cause hydrolysis of the alkoxide. As soon as the mixture has been formed, the mixture is caused or permitted to assume a state of relatively gentle motion (18), to promote condensation polymerization of the hydrolysis product, to form the complex metal hydroxide and/or hydrous oxide product. <IMAGE>
Patent GB-2184252-A (GB)
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 formed of two elements in tandem that are each cyclically driven to vary their birefringence to produce an output polarisation state that is swept over ranges such that the time integral of the system photodetector output becomes independent of polarisation. It is shown that, on the Poincare sphere, the birefringent elements must have orthogonal eigenstate axes and be driven at different but uniform rates in order for the time-weighted distribution of output polarisation states to be symmetrical about the sphere centre. The birefringence of the elements can thus be linear for one and circular (Faraday effect) for the other; or as shown can be linear for both if there is a relative physical orientation of 45 DEG , as between squeezer elements 40,41 applying stress to fibre 15. The drive waveforms are each triangular with amplitudes providing full-wave changes in birefringence. The system is a reflectometer using heterodyning of backscattered light (Fig. 1). <IMAGE>
Patent GB-2186424-A (GB)
Title: Method for producing integrated circuit interconnects
Inventor: WILLIAM BRIAN DAVID
IPC: H01L21/768
Filed: 1986-01-30
Abstract: A method for producing metal interconnect tracks which have a thickness at least as great as one half of their width. This is to allow closer spacing of integrated circuit components and thus a more optimal use of semiconductor surface space. The method (fig. 3) is based upon deposition of a relatively thick film (7) of dielectric (2 mu m) and the delineation of this film (7) using an etch resistant mask (9) and an anisotropic etch technique, this technique defining deep channels two microns or less in width to contain interconnect metal. Metal (13) is deposited by a conformal technique to infill the channels and thereafter surplus metal removed to define an interconnection pattern of metal tracks (15). In one example described, polyimide dielectric material is etched by oxygen plasma using a tungsten mask, and interconnect tungsten metal deposited by low pressure chemical vapour deposition. Alternatively, silicon dioxide dielectric material and aluminium masks and metallisation material may be employed with appropriate etchants.

Filed: 1986-05-02
Abstract: A video overlay controller accepts video inputs from diverse sources such as video disk players, video tape players, computer video generators, and the like, and provides synchronizing signals which stably lock the video sources to each other for simultaneous display. Synchronization is achieved within eight field times at most. Both interlaced and non-interlaced sources may be mixed for display.

The clock pulse frequency is controlled (i) in a horizontal sync section 102 wherein the oscillator 124 is controlled by a phase comparator 122 receiving the adapter horizontal sync signal CGAHSYNC and a horizontal reference signal NREF; (ii) in a vertical sync section 100 wherein the oscillator output can be so gated as to halve the effective frequency if the adapter vertical sync signal CGAVSYNC is detected as having more than a certain misalignment (one-half scan line) with the disk vertical sync signal NTSCVSYNC. <IMAGE>

IPC: G06F7/02
Filed: 1986-08-22
Abstract: A method of comparing the value A of an input digital word, the value of which may vary, with the value B of a fixed digital word, comprises programming a programmable array logic device in dependence on the fixed digital word so that, on supplying the input digital word to the device, the first most significant bit at which the input digital word and the fixed digital word differ is effectively checked, and in dependence on the result deriving an output signal which indicates whether or not the value of the input digital word exceeds the value of the fixed digital word. Fig. 2 shows the logic device arrangement for B=100 (binary) as an example. In general, for an N-bit input word a maximum of only N/2 product terms need be generated by the logic device for summation. <IMAGE>
