Title: High speed disc for video recordings - has groove with curved section to avoid excessive width with maximum depth (OE 15.10.77)
IPC: G11B7/12
Filed: 1976-04-20
Abstract: A recording disc has a uniform spiral groove widening outwards in cross-section towards the surface of the disc and having a variable depth to record the desired information. The cross-section of the groove is tht of an inverted bell, varying with the depth at the centre of the groove, so that the width of the groove at the top or open end hardly varies with changes in its depth to suit the modulations. Pref. the cross-section of the groove is symmetrical about its centre line and the sides of the groove are defined by the equation dx = do.e-(x/w)2 (wher dx is the depth of the groove at centre line, w the half-width of the groove at hte surface of the disc and dx is the depth of groove at distnce x from the centre line). Used in particular for high speed discs intended for recording video signals, where the disc revolves at about 1800 rpm and therefore the groove pitch needs to be as small as 4 mu. The method ensured that, when a groove reaches its maximum penetration depth, it is not so widened out at the mouth that it runs into the neighbouring groove.

Title: Packaging of asphalt in small polypropylene containers - which are melted and incorporated into final protective coating
IPC: B65D81/00
Filed: 1978-01-13
Abstract: A method of providing asphalt base coatings for pipes involves delivering the coating (10-25 wt.% asphalt, 75-90 wt% sand-lime aggregate) in containers which are chopped along with the coating material, melted and ultimately incorporated into the applied coating. The containers, which are constructed from polyethylene, polypropylene, or their copolymers are small and easily handled. (e.g. 50 lb when full). The presence of the aggregate, by aiding the shearing action during mixing, enables the mixing of the container material at temps. below 400 degrees F, i.e. below the asphalt flash point. Used for the application of corrosion resistant coatings. Unlike the other methods, the coating material need not be removed from the container. The small admixture (5 wt.%) of container material improves tensile, flexural and impressive properties of the final coating.

Title: Meat slicer depositing mechanism - has sliding plate consisting of several extendable late elements and has supporting mounting for packing paper roll
IPC: B26D7/32
Filed: 1978-03-06
Abstract: The meat slicing machine is fitted with a depositing table with an area which can be extended. the slicing cutter (3) driven by a control assembly inside the housing (2) deposits the slices of meat in direction of an arrow (5) onto a plate (4). The plate (4) is travelling on rollers (14) between stop lugs (15) and (16). The distance between the two represents the width of the plate unit in travelling direction. The depositing point for each row of slices remains the same in relation to the slicer assembly while the plate (4) travels step-by-step away from the slicer to create tows of slices. When the plate (4) reaches the terminal position ie. when the roller (14) stops at the lug (16) a carrier mechanism causes the uppermost plate unit (6) to slide on top of the next unit (7) underneath thereby extending the depositing area for a further supply of slices.

Title: Building panel manufacturing process - includes embedding collar type anchoring pins before curing panel in oven
IPC: E04C2/38
Filed: 1982-05-21
Abstract: The panel (1) is manufactured from resin bound, e.g. vermiculite or quartz sand with an average grain dia. of 250 microns and has a reinforcing (2) of wood. The steel pin (3) is driven into the wooden rib and has a head (4) and collar (5). The rib is provided with equidistant spaced pins. Head and collar may optionally be square or hexagonal. When the head is inserted into the panel before curing takes place, a cavity is formed in the panel. This results in a complete filling of the space around the collar. After positioning and fixing of the ribs to the panel, the panel is placed in a curing oven. Optionally the pin may have a barbed (6) configuration. An insulating material layer may be applied between the reinforcing ribs. The panel construction has a smooth surface, thus eliminating finishing operations.

Title: Loose laid carpet tile with rigid e.g. bituminous base layer - has resilient e.g. foam plastic layer between base and carpeting layer
IPC: B32B5/18
Filed: 1982-08-13
Abstract: Tile comprises an upper layer of carpeting material and a stiff base layer with a layer (2) of resilient material interposed. If the tile consists of more than three layers, the resilient layer (2) is preferably arranged directly below the carpeting material.

Date Mar. 7, 1990.A joint between pipes (12, 14) each having a liner (16, 18) of polyolefin such as polythene. The pipes are spaced apart and the liner protrudes from each and is joined to its neighbor by a fusion coupling (20). The pipes are interconnected by a shell (24, 26, 28) and epxoy cement grout (34) fills the space between the liner and the shell. The liner is inserted in the pipe after it has been reduced in diameter by passing it through a die. The pressure of gas or liquid within the liner in use is greater than the liner can withstand alone but the grout transfers pressure loading to the shell. In modifications the coupling is replaced by a PECAT coupling or by flanged couplings joined to the pipes by butt fusion or by electrofusion directly or using electrofusion couplers. The liner may be locked in position using electrofusion fittings to prevent change of dimensions by reversion.
