Title: Coffee mill for producing homogeneously ground coffee - has a worm of variable pitch preventing overgrinding and overheating
IPC: A47J42/36
Filed: 1974-01-14
Abstract: The coffee mill has a cylindrical worm of variable pitch which has a thread whose pitch decreases progressively downwards, the upper part of the worm being sharply inclined to the horizontal whilst the output of the groove between the adjoing coils of the worm is horizontal. Between its successive windings the thread of the worm defines a groove of generally helical shape, the depth and the pitch decreasing progressively downwards. This worm interacts with a container designed to receive the ground coffee so that the coffee beans placed in the neck of the worm are pased progressively downwards as the worm rotates. The full flavour and aroma of the beans are thereby preserved since there is no overgrinding.

Title: Plastic imitation leather mouldings - using mould formed from imprint of an assembly of leather pieces
IPC: D06N3/00
Filed: 1974-01-16
Abstract: A mould for producing plastic imitation leather is formed by securing (e.g. with clips, adhesive etc.) an assembly of leather pieces on a plane surface and filling the gaps between the leather pieces and then applying a moulding material to the surface of the assembly of leather pieces to produce an imprint of the assembly of leather pieces. This imprint is then coated with a non-stick material (e.g. a silicone) before applying a layer of polyurethane and a backing web which adheres to the layer of polyurethane during polymerisation of the layer. When removed from the imprint the surface of the polyurethane layer corresponds to the pattern of the assembly of leather pieces and has the appearance of leather. The method is used for producing imitation leather having a scaled or otherwise profiled surface and which is used for shoes. The imitation leather has a genuine appearance and is flexible and comfortable to wear. Pref. the support web applied to the layer of polyurethane is a textile material or leather.

Title: Knife mounting for trimming hollow mouldings - using a rotary holder to produce a progressive tangential cut with little drag
IPC: B26D3/16
Filed: 1974-02-18
Abstract: A cutting tool comprising a rotary mount turning coaxially w.r.t part of a hollow moulding to provide an eccentric support for a pivotted arm with a cutting blade mounted at one end. When the mount is turning, the angle of inclination of the knife holder is progressively varied to apply an increasing depth of cut towards the mount axis and hence impinge tangentially against the moulding. The knife holder is deflected either by centrifugal effects due to the magnitude and posn of the mass of the opposite end of the holder, or by contact between a bearing on the knife holder and a divergent guide moving coaxially with the rotary mount. Esp. for trimming or shaping the mouths of blow moulded bottles to ensure a good closure fit. Produces a cutting action with a limited degree of press or drag to avoid distortion of mould profiles weakened by elevated temps. The blade press. is readily controlled by varying the speed of rotation of the knife holder mount. The cutting mechanism returns to a posn clear of the moulding whenever mount rotation is stopped.
