Title: Roof cover trim
Inventor: COLE PETER WILLIAM
IPC: E04D13/15
Filed: 1984-02-02
Abstract: A trim for covering a joint between an edge or perimeter of a waterproof membrane (2) and a roof edge fillet (4) or other upward projection formed to prevent water flow from the roof edge comprises a plurality of lower elements (11) or cleats, secured in short discontinuous lengths, by fixings (15) over a generally horizontal surface of the waterproof roofing membrane (2) formed over the roof edge fillet (4), and at least one upper element (12), which is an elongate extrusion secured to the lower elements (11) by a snap-fit tongue and groove arrangement (19, 23), and which is so profiled that the upper element(s) (12), either alone or in conjunction with an adjacent, contiguous upper element (12), completely covers the lower element(s) (11), and the fixings (15) and prevents water penetration through such fixings (15). <IMAGE>

Title: Gear-indicating system
Inventor: BLEE TIMOTHY JOHN
IPC: B60W50/08
Filed: 1984-02-24
Abstract: A system for indicating which gear is indicated in the transmission of a vehicle is energised by transducers 30 and 32, transducer 30 providing an electrical output on a line 34 representing the engine speed of the vehicle and transducer 32 providing an electrical output on a line 36 representing the road speed of the vehicle. Lines 34 and 36 are fed to a dividing circuit 38 which measures the ratio of their signals. This ratio is solely dependent on the particular gear which is engaged, and the divider 38 compares the measured ratio with each of a number of pre-stored datum values, respectively equal to the ratios corresponding to the gears, and produces an electrical output on a line 40 which indicates which gear is engaged at any particular time. <IMAGE>

Title: Wall board fastener
Inventor: ADAMS GEORGE CHARLES
IPC: E04F13/08
Filed: 1984-02-25
Abstract: A wallboard fastener has a pair of flanges 22 on opposite sides of tongue portion 16 and a pair of impaling flanges 24 mounted to flanges 22 so as to extend over and parallel to base portion 14. The fastener includes apertures 18, 20 in both the base portion and the tongue portion and separate ribs 28, 30 are provided for the base portion and the tongue portion so that the tongue portion 16 is severable from the base portion 14 without deforming the rib structures. The fastener may include an additional rib structure 32 disposed across the interspace between the ribs in the base portion and the ribs in the tongue portion, and which is offset from the ribs of both portions. In use the flanges 24 penetrate an end face of a panel and a screw etc is passed through either aperture 18 or aperture 20 to secure the panel to another member. Removing the severable tongue 16 permits a panel 6 (Fig. 2), secured at right angles to the panel on which the fastener is mounted, to abut the flanges 22. <IMAGE>

Title: Variable surface acoustic wave device
Inventor: MAHER EAMONN FRANCIS PIUS
IPC: H03H9/02
Filed: 1984-03-22
Abstract: A surface acoustic wave device comprises a piezo-electric substrate (1) in combination with a photoconductive layer (2), and has an interdigital transducer comprising a pair of permanent electrode terminals 3, 4 spaced apart on the photoconductive layer (2), and a pattern of interleaved electrodes (11) which extend between the electrode terminals and which are formed by illuminating the photoconductive layer (2) so as to render it electrically conductive in the required pattern. The required pattern of illumination may be produced by means of an optical projection system utilising a mask or by means of a scanning optical or electron system, and by changing the pattern of illumination (which is relatively easy to achieve) the form of the interdigital transducer, and hence the operational characteristics of the surface acoustic wave device, will also be changed. <IMAGE>

Patent GB-2144397-A (GB)
Title: Liquid dispensing system and apparatus
Inventor: CARTWRIGHT GARRY ERNEST
IPC: G01F11/28
Filed: 1984-07-31
Abstract: Liquid dispensing apparatus comprises at least one liquid dispensing chamber (101,102), each having an associated prefill chamber (107,108) with displacement means (113,114) to transfer liquid therefrom to the associated dispensing chamber. Detector means (124,125) are provided in each dispensing chamber (101,102) and also (122,123) in each prefill chamber to sense the liquid level. Switch (116) actuates a solenoid of a selected displacement means (113,114) to transfer liquid to the associated dispensing chamber (101,102). A signal from the level detector means (124,125) causes deenergisation of the solenoid to retract the displacement means following which a signal is generated to energise actuation means to release a seal (119 or 120) at the outlet of the selected dispensing chamber to allow the contents thereof to be discharged into a container (106). The prefill chambers (107,108) are topped up from a liquid storage device (111). In a further embodiment, the prefill chambers are eliminated, and a displacement device located in the dispensing chamber acts to displace a measured volume of liquid therefrom. Means are provided for sensing the level of the liquid in the chambers and in the associated reservoir (15). <IMAGE>

Patent GB-2159973-A (GB)
Title: Microcapsules
Inventor: SCHUSTER GARY BENJAMIN
IPC: G03C1/00
Filed: 1985-06-07
Abstract: Photosensitive microcapsules have an internal phase including a photohardenable composition and a photo inhibitor precursor. A photosensitive imaging sheet comprises a support with a layer of the said microcapsules on one surface thereof. Imaging is performed in one arrangement by image-wise exposing such an imaging sheet to a first radiation, the imaging sheet having an image-forming agent associated with the microcapsules. The first radiation image-wise converts the precursor to a photohardening inhibitor. The image-wise exposed sheet is then uniformly exposed to a second radiation different from the first. This second radiation causes the photohardenable composition to harden in those areas in which hardening is not inhibited by the inhibitor. The imaging sheet is then subjected to a uniform rupturing force. The image-forming agent is activated and a negative image is formed.

Title: Printing press having a printing roller which always rotates in a unitary direction
Inventor: CHOU CHING-HO
IPC: B41F3/80
Filed: 1988-03-24
Abstract: In a printing press wherein the printing roller 21 effects a horizontally straight reciproating motion and means is provided for rotating the printing roller in a unitary direction whenever the roller is moved horizontally in any direction, two pinions 32A and 32B sleeved rotatably on the shaft 22 of the printing roller 21 rotate in opposite directions, each alternately clockwise and counterclockwise. When the printing roller 21 effects a horizontally straight reciporcating motion, and when either of the pinions 32A and 32B rotates in a predetermined direction, a locking member 35, 36 locks it on the shaft 22 by the engagement of a key 353, 363 and a keyway 313, 314 so that the printing roller 21 also rotates in the predeterminded direction.

Title: Video and or other tape or film cassettes
Inventor: DAVIS RAYMOND LESLIE
IPC: G11B23/087
Filed: 1988-04-26
Abstract: A cassette assembly, e.g. of standard VHS video tape format, includes stop means 40 within the cassette housing 14 movable between a blocking position, at which it co-acts with the tape transport, e.g. the take-up reel (32), so as to permit forward play of the tape 18 or other medium but restricts re-winding, and a free position at which full re-winding can take place. A key-actuated or other lock 42 of the assembly has to be operated to shift the stop means to the free condition so that the tape or other medium can be rewound. Thus the user of the tape or medium, e.g. a hirer from a video library, can only play the tape once without access to a key to effect rewinding, and thus a hire charge can be made for each viewing or other use of the tape or medium. The lock may be operated by a magnetic cord, optical key or cord, or infra-red device. The lock may act to prevent only a portion of the tape being re-played. <IMAGE>
