Title: Photopolymer printing plates having a dimpled printing surface
Inventor: CHIANG ALBERT C
IPC: G03F5/22
Filed: 1991-02-22
Abstract: A process for preparing photopolymer plates having a plurality of well-like depressions by exposing the photopolymer layer to actinic radiation through a photographic mask (30) containing optically transparent areas and optically opaque image areas, and a screen (10) having a plurality of opaque discrete dots (20) or other geometric shapes onto a photopolymer plate (40) and developing the plate, to form a plurality of depressions (51) in the relief planar surface of the exposed portions (50) of the photopolymer layer. The application of printing ink to the relief printing surface causes the depressions on the relief surface to act as ink reservoirs resulting in the application of a more even distribution of ink to surfaces to be printed, particularly where large solid areas are printed. <IMAGE>

Title: Cigarette making machine
Inventor: DAWSON JOHN
IPC: A24C5/39
Filed: 1991-05-01
Abstract: A cigarette making machine includes means for showering tobacco towards two suction bands (24, 24A) arranged to move towards one another so as to form two tobacco sub-streams from the showered tobacco and to merge the sub-streams, at a merger point (23) where the bands are closest, to form one stream, characterised by a wheel (25) formed with recesses (26) at circumferentially spaced positions around its periphery which are arranged to deliver measured quantities of tobacco to the merger point at regular intervals to form dense end portions. Dense end portions may also be achieved by reducing more air flow through at least one of the suction bands at localised areas. In another modification the suction bands may be replaced by fixed members having apertures therein through which air is blown to convey the tobacco along the surfaces of the members. <IMAGE>

Title: Regenerators
Inventor: GOODFELLOW JAMES HERBERT
IPC: F28D17/04
Filed: 1991-07-11
Abstract: A regenerator is provided with a port 28-31 at each end for flow through its matrix (e.g. of ceramic pebbles 25) alternately in either direction. The port 29, 31 on the hotter side of the matrix is connected by a forked conduit to two one- way valves 20 and 21, 22 and 23, which respectively control flow of heated air out from the matrix and flow of combustion products to the matrix. Operation of the one-way valves 20 and 21, 22 and 23 is automatic and is dependent on the pressure between each of them and the matrix which in turn is controlled by the usual flow control means 32-35 on the cooler side of the matrix. <IMAGE>

Title: Trigger for spring-type pretensioner
Inventor: NISHIZAWA MUNEO
IPC: B60R22/46
Filed: 1991-08-23
Abstract: The trigger 2 pretensions a vehicle seat belt B upon release of a preloaded spring 1. It comprises a first toggle 2A which is engaged with the operating end 1a of the spring and a second toggle 2B which is connected to an output member 3 of a collision sensor. The first toggle supports the spring load while set beyond its dead point and the second toggle, while set normally, restricts the operation of said first toggle. Thus when the second toggle is moved by the sensor beyond its dead point, it releases the first toggle, whereupon the pretensioner is operated. Moreover, the belt is clamped by a clamping arm (41, Fig. 2). <IMAGE>

Title: Slip control braking system
Inventor: SIGL ALFRED
IPC: B60T8/46
Filed: 1991-10-17
Abstract: A skid control braking system adapted for drive slip control in which detection of drive slip results in closure of valve (7), starting of pump (21) and opening of valve (26). Fluid pumped from accumulator (25) pressurises brake cylinders (6) to check the drive slip. When the drive slip has been eliminated pump (21) is switched off and valves (8) and (14) activated to return fluid from the brake cylinders (6) to the accumulator (25). Following this valves (8) (14) and (26) are returned to inactive position, and finally valve (7) is returned to its open position. <IMAGE>

Title: Ionization smoke detector
Inventor: KAMINAKA YOSHINORI
IPC: H01J47/02
Filed: 1991-11-25
Abstract: An intermediate electrode 8 of an ionization smoke detector has a plurality of support legs formed integrally on the periphery of the electrode 8 which may be simply inserted into openings of an insulating board 6 to fix and support the intermediate electrode, without using screws etc. Thus, the space needed to mount the intermediate electrode can be minimized.

Title: Thin film thickness monitoring and control.
Inventor: HANNOTIAU MICHEL
IPC: C03C17/32
Filed: 1993-09-10
Abstract: A method for monitoring the thickness and uniformity of a transparent coating applied to a substrate e.g. glass 10 in sheet form comprises directing polychromatic light at the coating at a plurality of locations, by means of a line source 16 and measuring the intensity of light reflected from said coating. At each location, the intensity of reflected light is measured at at least two discrete monitoring wavelengths and said measurements are processed 24 to generate an electrical signal which may be compared with one or more predetermined threshold values and with such electrical signals generated at other locations to yield indications of whether the thickness and uniformity of the coating lies within predetermined tolerance values. The first discrete monitoring wavelength lies in the range 400 to 480 nm (blue), the second in the range 580 to 750 nm (red), and a third in the range 480 to 580 nm (green) may also be used to provide an indication of refractive index of the coating. The difference of the red and blue reflectivity signals indicates coating thickness, and the average of the red, green and blue reflectivity signals indicates refractive index. The monitoring results may be used 28 to adjust the coating process. <IMAGE>
