Title: Three-terminal flasher unit
IPC: H03K3/02
Filed: 1971-01-12
Abstract: 1332867 Transistor pulse generators WAGNER ELECTRIC CORP 12 Jan 1971 1383/71 Heading H3T [Also in Division G4] In a flasher unit having power 10, load 14 and earth terminals and a signal circuit comprising a relay 18 having a coil 24 and magnetically movable contacts connectible through relay terminals 18, 20, the relay terminal 18 is connected directly to the input terminal of a solid state switching device 12, a timing circuit comprising a capacitance 26 is connected directly in parallel with the relay coil and a resistance 28 is connected in series with both the capacitance 26 and the relay coil 24 between two flasher unit terminals. The timing circuit is operative when the first and second output terminals of the solid state switching device are connected in series with a source of D.C. and a load via the power and load terminals and the signal circuit is connected to the earth terminal to alternately energize and de-energize the coil thereby causing the first and second terminals of the relay to be alternately connected and disconnected so as to cause the solid state switching device to permit an intermittent D.C. to flow through the load. The load 32 may be one or more signal lamps of an automotive signalling circuit which are flashed by the flasher unit when switch 14 is closed. This causes the capacitor 26 to charge via 28 and the load 32 until the voltage across the coil 24 energizes the reed relay contacts 18, 20 so as to bias transistor 12 and light the lamp 32. Capacitor 26 now discharges through coil 24, resistor 28 and the emitter collector of transistor 12 until the coil 24 releases contacts 18, 20 and the transistor 10 turns off to de-energize the lamp 32. Capacitor 26 now recharges and the above is repeated. Resistor 30 may be connected to prevent thermal runaway when the base is open circuited. The circuit may be modified (Fig. 2, not shown) by including a diode (34) in the connection between the resistors 28 and 10 and connecting the negative terminal of the capacitor 26 to contact 20 so as to lengthen the on period by allowing the capacitor 26 to discharge only through the coil 24. In a further modification (Fig. 4, not shown) transistor 12 conducts immediately the switch 14 is closed, capacitor 26 charges via the transistor 12, a diode (34) and resistor 22 and when the voltage across the coil 24 is sufficient the relay contacts 18, 20 close so as to shunt the base emitter junction of the transistor and render it non-conductive. The capacitor then discharges via the coil until the contacts 18, 20 again open and the above operation is repeated.

Abstract: 1339444 Injection moulding IMPERIAL CHEMICAL INDUSTRIES Ltd 22 Nov 1971 [30 Nov 1970] 48711/71 Divided out of 1339443 Heading B5A Articles having dissimilar skin and core materials are formed by injecting skin material (A) or skin material followed by core material (B) through a first sprue channel, e.g. 1, and injecting skin material (A) and/or core material (C) through at least two sprue channels, e.g. 2, 6, displaced from the first channel, core material (C) or skin material followed by core material (B) being injected through at least one of the sprue channels so that core material is injected to within skin material already injected into the mould cavity. Embodiments having three and five sprue channels are described. If three sprue channels are used, eight alternatives exist i.e. A, A, C; A,C,C; B,A,A; B,A,C; B,C,C; B,B,A; B, B, C; and B, B, B. If skin material is injected through two channels, the materials, e.g. 9, 10, may be injected simultaneously or sequentially and may be different, e.g. additives such as pigments may vary. Skin material need not be injected through both channels before core material is injected through the third channel. Core material, e.g. 3, may be injected during or after injection of skin material. If core material is injected through two sprue channels, the materials may be injected simultaneously or sequentially and may be different (e.g. 8, 10, Fig. 6). Core material injected through one channel may extend skin material already present in the cavity to below another channel so that core material may then be injected therethrough, e.g. (Fig. 5). The core material which may be foamed may be the same as the skin material except for additives which may be different or which may be the same but present in different proportions. The core materials may become integral or remain separated by skin material (Fig. 6). Additional skin material may be injected after injection of core material to reduce surface exposure of core material (Fig. 9). More skin material than is desired in the moulded article may be injected with the excess material being forced back through the respective channel by the injection of core material (see Specification 1,339,445). Examples of moulds, plastics materials and articles produced are as disclosed in parent Specification 1,339,443.
