Title: Method of developing positive- acting photosensitive lithographic printing plate precursor
IPC: G03F7/30
Filed: 1980-02-26
Abstract: A method of using an aqueous solution of an alkali metal silicate to develop an imagewise exposed positive- acting photosensitive lithographic printing plate precursor having on an aluminium support a photosensitive layer containing an o-quinonediazide compound, wherein (1) a decrease in the activity of said developer resulting from development is compensated for by adding to said developer a first replenisher composed of an aqueous solution having an alkalinity higher than that of said developer and (2) a second replenisher composed of an aqueous solution having an alkalinity higher than that of said developer is added to said developer either (a) continuously in a predetermined amount or (b) at a predetermined interval in a predetermined amount. Preferably in each solution at least 20% of the alkali metal is potassium; this prevents formation of a deposit which would clog filters in an automatic developing machine. Equations are given for determining the amounts of replenishers.

Title: Improvements in or relating to measuring apparatus
IPC: A43D1/04
Filed: 1980-05-14
Abstract: There is described a measuring apparatus for providing a set of cartesian co-ordinates defining the shape of an article such as a shoe. A table 42 with an aperture 41 for a carrier for the article 10 has two holes to receive a pivot pin for each of three arms 43, 44, 45, enabling each arm to be pivoted at 47 about either of its ends, and each arm carries a rod 48 mounting a contact element 49 which is laterally movable relative to the arm in a direction normal to the lengthwise dimension of the arm. Displacements of the contact elements, which are used to touch points on the surface of the articles, are transmitted to a computer capable of defining any position of any one of the contact elements in cartesian co-ordinates relative to a common origin. The carrier is guided for movement normal to the plane of the table and parallel to the X axis, and the Y and Z co- ordinates are measured in the plane of the table. From these co-ordinates, duly recorded, a screen image of the article can be derived. <IMAGE>

Patent GB-2053445-A (GB)
Title: Ribbed constructional assembly for heat transfer in heat exchangers
IPC: F28F13/00
Filed: 1980-06-25
Abstract: A ribbed construction assembled from sheet metal bands for improved heat transfer, suitably built into the pipes of heat exchangers forms the arrangement of the invention. The ribbed construction assembled from toothed metal bands ensures the improved heat transfer primarily by slowing down the velocity of the medium flowing in the center of the pipe; furthermore it improves the temperature distribution of the flowing medium by means of metallic contact and mixing. Although the ribs are easily movable in the pipe, a significant portion of the tooth-ends is in loose contact with the inner pipe wall, which likewise improves the heat transfer.
Patent GB-2076335-A (GB)
Title: Apparatus and method for sealing thermoplastic tips to containers
IPC: B29C65/08
Filed: 1980-07-21
Abstract: Adjacent surfaces of man-made plastics elements, 0.9. a thermoplastic dispensing tip and a thermoplastic container of a dispenser are welded to one another by generating localized heat at the interface of the surfaces. After insertion of the base of a dispensing tip (22), Fig. 4, within the neck (12) of a filled container (10), ultrasonic vibrations may be transmitted by a probe (30) in contact with the dispensing tip (22) across the interfacing surfaces (54). of the base of the dispensing tip (22) base and the interior of the container neck (12). Alternatively, the base of a dispensing tip (54), Fig. 8, is inserted within a tight fitting neck of a filled container (40) simultaneous with or prior to relative rotational movement therebetween. The heat generated by frictional interference between the dispensing tip base and the interior surface of the neck as a result of the relative rotation therebetween raises the temperature of the interfacing surface of the dispensing tip base and container neck interior sufficiently to weld these surfaces to one another. To prevent pressure build-up in the container (40), a plunger (56) pushes in a wall thereof to compensate for the volume displacement caused by the insertion of the base (58) of the tip (54). <IMAGE>

IPC: F16M1/04
Filed: 1981-05-14
Abstract: A skid is disclosed which is particularly suitable for supporting rotating machinery in environments where it is exposed to temperature variations and external mechanical forces and where failure of the machinery can result in the generation of an extremely high torque which has to be absorbed. The skid basically comprises a machinery support platform which is connected to an elongate torsion resisting member in torque transmitting relationship and only three spaced supporting members each incorporating a universal joint and rigidly connected to the torsion resisting member. The torsion resisting member is preferably of hollow circular cross-section throughout its length and is disposed below the medial centre line of the support platform and the three supporting members are disposed at the corners of an isosceles triangle and incorporate means allowing for limited movement of the torsion resisting member relative thereto.

Title: Actuating mechanism for small arms
IPC: F41A19/00
Filed: 1981-07-10
Abstract: A self-loading firearm for firing rubber bullets and the like has an actuating mechanism comprising a toggle linkage (13, 17) which is straightened on operation of the trigger (6) against its spring bias. Initial straightening of the toggle linkage (13, 17) moves the breech block (15) forward to locate a round of ammunition in a short socket (83) at the chamber end of the barrel (1). As the toggle linkage (13, 17) moves over centre it locks the breech block (15) forward and displaces a sear (29) to release the firing pin (20). The round is fired with its case virtually unsupported. On release of the trigger (6) the toggle mechanism (13, 14, 16, 17, 18) is bent so withdrawing the breech block (15) and the spent round which is automatically ejected. The firing pin (20) is simultaneously re-cocked. Rotary (2) and vertical stacking rechargeable magazines are described, from which a fresh round is automatically fed to the breech on ejection of a spent round.
