Patent GB-2064459-A (GB)
Title: Positioning apparatus and conveying apparatus
IPC: B65G47/24
Filed: 1980-11-24
Abstract: Egg-like confectionery are orientated by feeding them onto rollers (10) which are carried by endless conveyor chains (11) and pass under guides (30, 31 and 32). The rollers (10) have grooves (19) positioned so that the guides (30) initially prevent the eggs from entering the grooves. The rollers (10) are rotated initially so as to cause incorrectly orientated eggs, i.e. eggs having their sharp ends pointing towards the guide (31), to engage the latter, the correctly orientated eggs moving in the opposite direction, as they pass through the guide (30), to enter the grooves (19). The incorrectly orientated eggs are turned through 180 DEG  by guide (32) before entering the grooves (19). The eggs are supplied to the rollers (10) either by a bucket conveyor (33) or by a rotary feed device comprising egg- separating plates (44).

Patent GB-2093643-A (GB)
Title: DC-to-DC converter
IPC: H02M3/338
Filed: 1981-02-17
Abstract: In a DC-to-DC converter, two control transistors (T1, T2) are pulse-controlled (Q1, Q2) so as to conduct alternately. Each such transistor has its collector connected to a DC supply via a resistor (R1, R2). Each control transistor, when it conducts derives a pulse through a primary on a control transformer (TF1), the pulses from the two transistors (T1, T2) being oppositely poled. There are two switching transistors (T3, T4) in series across the DC supply to be converted, and they conduct alternately to drive pulses in the opposite sense through a primary winding on an output transformer (TF2). The connection to this output winding is via a further transformer winding via which regenerative feedback for the switching transistor is derived. Thus the primary of output transformer (TF2) receives an alternating pulsed waveform, which is induced into the output transformer's secondary winding. This is rectified by a full- wave rectifier D1-D2 with a choke input filter L--C3 to give a DC output. The arrangement can also function as an inverter if the rectifier circuitry is not included. <IMAGE>
