Title: An explosive cutting device
Inventor: LAZARI LAZARIS G
IPC: E21B29/12
Filed: 1986-04-25
Abstract: An explosive cutting device for removing sections of a well casing pipe within a borehole comprises, in one embodiment, a plurality of lined cavity charges 2 defining a tubular shaped matrix of criss-crossing explosive charge lines. The charge 2 terminate in a ring 6 of lined cavity charge-on each end of the tubular matrix. Between the rings 6 the lined cavity charges define spaced crossover points 7. Spaced initiation points 3 around the ring 6 at one end of the tubular matrix provide for detonation to simultaneously begin from each initiation point. The casing is severed at 6 and portions opposite the lined charges are fragmented and dislodged to the middle of the well where they can drop downhole and do not interfere with the drilling head during side-tracking. in another embodiment separate cavity charges (as shown-in Figs. 4-7) can be used sequentially to cut the casing, first along one set of parallel lines and then along a second transverse set, when the geological formation does not permit casing expansion. <IMAGE>

Title: Roll-on dispensing package
Inventor: GIBLING EDWARD J
IPC: A45D34/04
Filed: 1987-07-14
Abstract: A dispensing package is provided for delivery of liquids such as antiperspirants. The package has a fitment (30) mounted upon a container (8) holding liquid product. Within the fitment is a socket (28) cradling an oval roller (40). At either ends of the socket are a pair of arms (24) which communicate with the ends of the roller and permit the roller to travel vertically within the socket. A spring (10) with one or more upward protruding spuds (14) is thrust from below through a floor base aperture (52) and presses against the roller. Normally the spring pushes the spud through the aperture to seal the container. When the roller is pressed against a treating surface, e.g. skin, the roller pushes downward upon the spud thereby opening the floor base aperture permitting product to exit the container and be spread by the roller onto treatment surfaces. <IMAGE>

Title: Improvements in collation assemblies
Inventor: OBEROI BHUSHAN KUMAR
IPC: B65G57/14
Filed: 1987-11-13
Abstract: The invention relates to apparatus for collating and stacking building components, such as roof tiles. The apparatus comprises pairs of shelves (24) for receiving and supporting tiles which are fed into the shelves continuously by means of a conveyor arrangement.

Title: Method and apparatus for clearing debris from within a mould
Inventor: MUGHAL HAMID GHAFOOR
IPC: B22C9/18
Filed: 1988-09-16
Abstract: The mould cavity has an inlet and an outlet and extraction means (3, 4, 5, 6, 11), usually including a powerful fan, joined to the inlet or the outlet and capable of creating a current of air through the cavity of sufficient velocity to create turbulent flow to disturb and extract from the mould cavity substantially all debris lying on the moulding surfaces. The flow pattern or velocity of the air current may be varied by varying the size or shape of the inlet or outlet, e.g. by progressive placement of a mould cope. The inlet and outlet are afforded by orifices and passages, e.g. ingates, normally provided in the mould. The fan (3) preferably is an extractor; its function may be assisted by directing air jets into the mould inlet, e.g. by use of a perforated plate (Fig. 4, not shown). In a production fine where moulds move in turn over the apparatus, a brush or inflatable seal seals the fan inlet duct to the mould lower surface. <IMAGE>

Title: A lamp housing and method for making it
Inventor: STANWAY PETER JAMES BINNEY
IPC: F21Y103/37
Filed: 1989-12-01
Abstract: A lamp housing is formed from a blank (1) cut from a thin sheet of metal, which is preferably mild steel. The blank (1) has requisite holes (5) slots (6) and flaps (2a and 2b) cut in it. It also has lines of weakness (21) in it, which may be formed at the same stage as the blank (1).

IPC: G06F7/76
Filed: 1991-01-15
Abstract: A decoder circuit for generating mask patterns on a plurality of output terminals C1....C7 in response to a multibit binary input number X0....X2 uses a plurality of two-input multiplexers arranged in parallel paths to form one stage (Fig. 5) or as a tree structure consisting of several cascaded stages of binary or higher order and controlled by functions of the bits of an input number to produce a logic "1" voltage on a number of output terminals equal to the input number and a logic "0" voltage on the remaining output terminals. Another embodiment can work selectively as a single decoder or two (with identical outputs) of half the size. Another possibility is to generate a mask as above, store it, generate another mask as above, then logically combine the two masks to give a pattern with a sequence of 1s between two sequences of 0s. <IMAGE>
