Patent GB-2051775-A (GB)
Title: Bonding electrical components to thick film conductors
IPC: H05K3/32
Filed: 1979-06-27
Abstract: In a process for bonding and electrically connecting a first thick film electrical conductor on an electrical component or component part, such as a ceramic chip capacitor or resistor, to a second thick film electrical conductor on a support member, in which at least one of the first and/or second conductors consists of a dispersion of electrically conducting particles in a glass or glass-ceramic matrix, the component or component part is located on the supporting member such that the first conductor, or a composition adapted to produce it by heating is in contact with the second conductor or a composition adapted to produce it by heating. Heat is applied to cause fusion of the glass or glass-ceramic in at least one of the conductors or compositions and on cooling, the first conductor becomes bonded and electrically connected to the second conductor. The use of solder or other bonding agent is thus obviated.

Title: Two stage starter drive system
IPC: F02N15/00
Filed: 1979-11-21
Abstract: A two stage positive shift starter drive system for an internal combustion engine is disclosed. A pair of electrical switches (60, 62) are sequentially actuated by an actuator solenoid (14) engaging the starter drive's pinion gear (12) with the engine's ring gear (18). The first switch (62) actuated after a predetermined displacement of the solenoid's armature applies electrical power to the cranking motor through a resistance (81) connected in series with the cranking motor (10) and connected in parallel with the solenoid's pull in coil (24). The resistance reduces the electrical power applied to the cranking motor and the potential across the solenoids pull-in coil thereby reducing the rotational speed and the engagement force applied to the pinion gear. Ending travel of the armature closes the second switch (60), applying full power to the cranking motor permitting normal cranking of the engine with the pinion gear fully engaged with the ring gear. <IMAGE>
Patent GB-2040788-A (GB)
Title: Moulding foamed plastics
IPC: B29C44/58
Filed: 1980-01-15
Abstract: In a method of making moulded objects (62) from foamed plastics, e.g foamed polystyrene, the plastics raw material is introduced in the form of pre-expanded beads containing an expanding agent into a divisible mould (2) and is subjected in this mould to the action of a hot, gaseous foaming agent, which causes the beads to fuse together while further expanding. The thus obtained foam is, before the moulding is removed from the mould, stabilized by forcing through it a stabilizing agent in the form of a gas, e.g. air. The foaming and stabilizing operation can be repeated. A vacuum can also be applied to the moulded object during the working cycle. The relevant mould may possess, instead of the usual nozzles (26) or slits, mould inner walls (28, 30) of porous material, e.g. sintered metal. <IMAGE>
Patent GB-2045983-A (GB)
Title: Electrical Generator Voltage Regulation
IPC: H02P9/14
Filed: 1980-02-11
Abstract: By means of the control windings (16), the reluctance of ferromagnetic material in the magnetic-circuit is altered, whereby the flux in the generator, and hence the output voltage, made be regulated. The output windings and the control windings (16) are on the stator with the control winding connected to a d.c. source. Alternatively, the output windings and the control windings may be on the rotor and in this case control current is applied to the control windings by conventional means such as slip rings. Feedback from the rectified generator output may be compared against a reference voltage and cause an amplifier (28) to vary the DC fed on the control windings. Alternatively, (Figure 3e, not shown) as long as the output voltage does not exceed a given voltage no control current is generated, otherwise feedback causes abrupt saturation to reduce the output current to prevent demagnetisation of the rotor. <IMAGE>
