Title: Plastic bags for stacking - formed by intermittently cutting and welding continuous plastic tube
IPC: B31B19/98
Filed: 1974-11-05
Abstract: A continuous plastic tube (opt. with a longitudinal seam) is continuously advanced and cut and welded at spaced positions to form plastic bags and the bags are transferred to a stacking position on a feed conveyor during the period in which the feed conveyor advances a completed pile away from the stacking position whereby continuous feed of the plastic tube is not interrupted and the processing speed is increased. Pref. newly formed bags are formed into an intermediate pile which is transferred to the stacking position such that the leading edge of the intermediate pile overlaps the trailing edge of the adjacent completed pile.

Title: Fuel injection system for supercharged engine - has pneumatic actuating diaphragm connected to electromagnetic air pressure regulator
IPC: F02D9/02
Filed: 1975-07-11
Abstract: The butterfly valve (10) is controlled by a lever connected by a linkage (13) to the accelerator pedal (14). A second lever (16) is provided with an adjustable stop (17) for the pedal link (12) and is connected to a pneumatic actuator (19). One side of the diaphragm (23) is exposed to the atmosphere, and the other is connected to the electromagnetic valve (29). When the driver operates the switch (26), the valve (29) is energised and connects the underside of the diaphragm (23) to the inlet manifold (9). This causes the lever (16) to rotate and open the butterfly valve (12) to a position which maintains a constant pressure in the inlet manifold. This constant pressure is chosen to provide conditions of maximum engine thermal efficiency.

Title: Locating actuator piston for sliding cover - locating balls on sleeve engage recesses on auxiliary sleeve instead of on piston
IPC: F15B15/26
Filed: 1975-07-31
Abstract: An actuator cylinder of the type used to operate smoke or lighting cowls or similar sliding covers, has a piston (4) mounted on balls (5) which fit in grooves on the piston wall and has a locating sleeve (9) inside the outer casing, mounted around the spindle (2) which keeps a set of locating balls (12) in the unlocked position, pushed by a spring (10) so that the sleeve can move axially. The outside diameter of this sleeve is equal to a further locating sleeve (6) mounted behind the piston so that one sleeve fits over the other, locked by the balls (12) between them in the end position of the piston. This enables the piston to be made of a soft metal such as aluminium.

Title: Miniature motor with permanent magnet stator - has disc type rotor slotted to produce effect of discrete poles
IPC: H02K21/38
Filed: 1975-08-22
Abstract: The miniature motor has a reluctance type rotor to increase its efficiency and frequency response, which has a disc mounted on a shaft (1) located in bearings (3) in the stator. The disc is slotted thus providing a high reluctance area and forming effectively isolated teeth (12d, 12e). The rotor is partially enclosed by the magnet system (8) of the exciting coil (9). On the rotor face opposite the exciting coil is the stator with segmental permanent magnets of alternating polarity. Alternating current applied to the exciting coil (9) results in alternating magnetic polarity of the effective teeth (12d, 12e) on the rotor. A torque producing reaction with the stator poles results causing rotation whose speed is related to the applied frequency.

Title: Rotary mixer for yoghurt etc. already in final containers - has variable geometry beater to pass through neck of container
IPC: A23C9/12
Filed: 1977-04-27
Abstract: The containers have a chamber to which the only access is via a neck passage of narrower cross-section than the chamber. The machine has a mounting to hold a container coaxially beneath a vertical, rotary agitator shaft. A beater is fixed to the agitator shaft and the shaft and container moved relatively towards each other so that the beater enters the container chamber. After rotary mixing of the prod. in the container, the shaft and beater are withdrawn clear of the container. The beater is of adjustable cross-section which is reduced to pass through the neck passage and enlarged inside the container during mixing. The beater pref. comprises a long blade pivoted on a horizontal axis passing through the vertical axis of the agitator shaft. The pivotal axis is below the centre of gravity of the blade so that the top of the blade tends to fall away from the agitator shaft axis to a position limited by stop pegs. Used for mixing yoghurst and similar prods. after filling into containers for distribution, e.g. of about 20 cl. to 1 l. capacity. Method obviates the need for premix storage vessels and large, expensive mixing plant.
