Title: A nibbling tool for shearing sheet material
IPC: B23D27/02
Filed: 1982-05-28
Abstract: A nibbling tool for sheet material e.g. metal or plastics material and attachment to a power tool e.g. air or electric drill or air motor is so constructed that the cutting direction can be readily varied from the Fig. 2 position i.e. parallel to the drive shaft 30 for planar sheet to a direction at right angles thereto, for corrugated or contoured sheet. The drive shaft 30 is coupled to a piston 50 carrying a coaxial punch 52 in a housing 40. A die-carrying member 80 is secured, at 94, to a piston guide 70, the head 71 of which seats in an abutment in the housing to prevent rotation of the guide, and is locked to the housing by a nut 92. Release of the nut allows the guide to be moved into the housing to disengage the head from its seat; the guide is then rotated, together with the die carrying member, returned to its axial position and re-locked in its new orientation. The nibbling stroke is variable by axial adjustment of the die carrier on the guide 70. <IMAGE>

IPC: B01D25/21
Filed: 1982-11-08
Abstract: A filter plate and inflatable diaphragm assembly for use in a filter press, comprising a horizontal stack of such assemblies interleaved with recess plates (12), comprises a plate (11) and a diaphragm (19). Plate (11) has a relatively thick peripheral portion (13) and staybosses (20). Adjacent portion (13) and staybosses (20) the diaphragm does not overlie the plate (11) but has lips (23, 24) accommodated in recesses (25, 26) in the plate (10).

Title: Cathode ray storage tube
Inventor: SMOLLETT MAX
IPC: H01J29/10
Filed: 1983-04-22
Abstract: A storage tube target structure (22) scannable at high speed using a low current, low voltage write electron beam (18). In one embodiment the target structure (22) comprises a buffer memory formed by a phosphor screen (24) on which a light output is produced in response to the incident electron beam, whose gain may have been multiplied in a channel plate electron multiplier (34). A silicon diode wafer (28) is optically coupled to the screen (24) by a fibre optic plate (26). The light incident on the input side of wafer (28) produces hole-electron pairs which cause the diodes (30) to be charged. These diodes (30) are discharged by a low current, low voltage read beam (20) which has optionally undergone current multiplication in another channel plate electron multiplier (36). By using a buffer memory (24) and low energy write and read beam (18, 20) it is possible to obtain very fast writing and reading, for example 1 x 10<9> bits/second write or read. <IMAGE>

Title: Protecting optical instruments against thermal radiation
Inventor: BALDERSTON JOHN
IPC: G02B26/02
Filed: 1984-04-12
Abstract: The invention protects the eyes of users of telescopic weapon sights, eg tank gunners, against thermal radiation from the flash produced by battlefield nuclear weapons. A fast-acting reversible opto-electrical attenuating screen 2, eg of PLZT, is located across the field of view of the sight 1, a UV-activated fast-acting reversible photochromic filter 3 beyond the screen 2, an infra-red filter 4,5 beyond filter 3 and a mechanical shutter 6 beyond filter 4,5. Closure of shutter 6 and switching of screen 2 is initiated by the flash, but the shutter can only close relatively slowly. While it is closing, protection is given by the remaining elements which individually also protect succeeding elements from damage due to thermal overloading.

Filed: 1984-04-26
Abstract: A mole drainer is described having a blade (64) pivotably attached to a main beam (10) and secured by a shear pin (72) which under exceptional impact stress will shear and permit the blade to swing backwards to minimise the damage which would otherwise occur. Another mole drainer design is described in which the main beam (10) will articulate relative to a subframe which latter is adapted to be mounted on a tractor three-point linkage and chains limit the extent of the articulation of the main beam relative to the subframe. In a further design a mole drainer having such a subframe is combined with an intermediate frame adapted itself to be fixed to a tractor three-point linkage on the one hand and to provide quick hitch mounting points for the subframe of the mole drainer on the other hand. <IMAGE>
