Title: Distilled spirit separator - uses hydrometer to divert flow when specific gravity changes
IPC: C12H6/02
Filed: 1971-12-15
Abstract: The delivery of spirit from a still is automatically diverted when the S.G. of the liq. changes to a predetermined extent. The diversion is effected by a mechanical linkage, actuated by vertical displacement of a hydrometer, operating as an alcoholometer. The rising hydrometer touches one end of a balanced, pivoted tube and tilts it out of equilibrium. The tube contains a free-running ball adding to the momentum of the swinging tube which is used to operate the diverting linkage. The device is simple, cheap and more reliable and robust than electrical systems.

Title: Textile articles formed by welding edges of thermoplastic panels - arranged in pile with insulating layers between them
IPC: B29C65/74
Filed: 1974-07-11
Abstract: A textile article is formed by superimposing pairs of article panels of fabric containing thermoplastic fibres to form a pile with layers of insulating(inert) material (e.G. paper) sandwiched between the pairs of article panels. The pile is then pref. cut with shaped cutter blades to cut two pairs of article panels, the blades being pref. heated so that simultaneously with cutting the edges of the cut pairs of article panels are fused together to form the finished article. Alternatively the article panels may be pre-cut before being formed into a pile during which their edges are fused together. The method is used particularly for making garments eg. T-shirts. The articles can be produced cheaply. Pref. the outer faces of the article panels are covered with an ink based pattern, the link being unaffected by the temperatures required to melt the thermoplastic fibres.

Title: Locknut and bolt for overhead electric cables - has extra long bolt with interrupted thread forming locking length
IPC: H02G7/05
Filed: 1974-10-11
Abstract: The bolt (300) has a threaded shank divided into two parts (303) and (302) by a plain portion (301), the diameter of which is equal to the core diameter of the thread. The bolt (300) is pushed through a hole in the cable lug (10) and the nut (110) is screwed over the end section of thread (302) until the locking slit is over the plain portion (301). The bolt shank is then slid into the slot of an attachment fixing and then the lug is pressed against the fixing so that a dowel pin engages in a locking hole. The nut (110) is then fully tightened, the spanner torque being resisted by the dowel pin. When removing the lug the slackened nut is retained by the end thread (312).

Title: Stator with end plate and finger assembly of reduced height - has nonmagnetic steel pressure fingers located in grooves
IPC: H02K1/16
Filed: 1975-03-24
Abstract: The stator of an electric machine has a box core with magnetic steel end plates that press the core laminae together via non-magnetic steel fingers. These pressure fingers (6) are located in grooves (7) in the plates (5). The grooves extend radially with respect to the stator axis (1). The arrangement reduces the height of the compressing devices (plates and fingers) and thereby reduces the size of the stator core and winding. The overhang of the stator winding bars can be reduced by 100 to 120 mm, which also increases efficiency and reduces materials costs.
