Title: Safety fuse comprising low-melting alloy - carrying thin coating covered by heat-setting adhesive, the alloy disintegrating into particles under surface tension when heated
Inventor: ISHIOKA TAKASHI
IPC: H01H85/041
Filed: 1977-02-11
Abstract: Electric safety fuse features a membrane of resin, grease or an oil having a lower m.pt. than that of a fusible alloy onto which it is applied and which is connected to electric conductors. The thickness of the membrane is such that its vol. ensures that the alloy disintegrates, under the influence of surface tension, into small beads when it melts, and is deposited on the sides of the electric conductors. The membrane is, in turn, coated with a heat-stable adhesive, e.g. an epoxy resin, or an inorganic material. The safety use is effective at a pre-determined, relatively high, temp. Its performance is uniform even though its mfr. is suitable for mass prodn.

Title: Ribbon loom heald control - has ratchet coupling from drive shaft to reduce length of control movement to increase working speed
IPC: D03C3/00
Filed: 1977-05-18
Abstract: The control mechanism for the healds of a ribbon loom, working from a perforated pattern control card, has a ratchet coupling to give an intermittent rotary movement from the drive shaft to be translated into a reciprocating movement to the thread guides at the healds. A carrier is keyed to the constantly-rotating drive shaft acting with a rotary counter disc with >=1 coupling jaw which is spring loaded for selective engagement, or disengagement to give a freewheel action. Electro-magnets are used, operated by the pattern control, to determine whether the coupling is in the engaged or in the freewheel mode, to actuate an operating unit which oscillates synchronously with the drive shaft. There is a lever linkage from the counter disc to the thread guides at the healds. The design ensures that control movements are kept short so that operating speeds are increased while retaining a positive control action.

Title: Control for drilling machine - has spring in quill with pressure switch to switch on warning light to indicate excess load from worn drill
Inventor: SCHELL FRIEDRICH
IPC: B23Q11/04
Filed: 1977-10-22
Abstract: The drilling machine has its drill spindle mounted in a linear bearing to permit a limited upward movement against spring. When the resistance to the drill exceeds the load of the spring the flange is lifted clear of the orifice and increases the flow of air from the pressure switch. This increased flow causes a pressure drop which actuates the pressure switch and switches on a warning light to indicate that the drill must be changed. If the drill force increases still further the second pressure switch stops the machine.
