Title: Small signal amplifier
IPC: H03F3/18
Filed: 1973-07-06
Abstract: 1410133 Transistor amplifying circuits MOTOROLA Ltd 6 July 1973 [12 July 1972] 32325/73 Heading H3T A small-signal amplifier comprises a first transistor 15<1> with its collector earthed and its emitter connected to the base of a second transistor 16<1> of opposite conductivity type, which is in common emitter connection. The transistor 16<1> is coupled to an emitter-follower output stage 20<1>, from the emitter of which current is obtained for the transistor 15<1>, via feedback resistor 25<1>. The resistors are so chosen that the quiescent potential of the output terminal 22<1> is mid-way between that of the supply terminal 18<1> and earth. As shown a microphone 12<1> is coupled to the amplifier via resistors 31<1>, 32<1> and a shunt diode 30<1> which limits positive-going signals, negative-going signals being limited by the base-collector diode formed by transistor 15<1>. In a simplified arrangement (Fig. 1, not shown) a microphone is connected directly to the base of the first transistor.

Abstract: 485,931. Channelling &c. boot soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., and RIVINGTON, A. A. Nov. 26, 1936, No. 32347. [Class 31 (i)] In a machine for performing a marginal cutting operation on a boot sole in which a head is pivoted to a fixed frame about an axis perpendicular to that of a rotary feed wheel carried by the a co-operating presser wheel being provided on the head, the head carries a slide which consists of two limbs embracing and adapted to grip a part of the head to secure the slide in adjusted position, a tool or tools being mounted on the slide. The invention relates to the mounting of the tools on the slide and to the mounting of an edge gauge for movement with the feed wheel upon axial adjustment thereof. In the channelling and grooving machine shown, the head 28 is adjustably pivoted in a lug 34 of the frame 32 by a pin 106 and slot 108 and is guided by a lug 96 engaging between ears of a lug 36 when it is adjusted laterally by a screw 98. The head 28 can be raised against an adjustable spring 114 by means of a treadle 67 acting on a lever 126. A rod 116 associated with the spring has two bores at right-angles in its upper end to receive a bolt 125 on the head 28. A presser wheel 22 and a presser foot 24 are mounted on the head. A feed wheel 20 as described in Specification 21898/09, [Class 31 (i)], is mounted on the frame and is secured to a bevel gear 56 meshing with a bevel gear on a rotary edge gauge 76. The feed wheel and edge gauge are together movable to the right against the action of a spring in a housing 64 by means of a treadle operating a rod 78 and lever 80; the treadle is pivoted to a base plate and depresses a lever on the base plate to which the rod is connected. The tools 26, 30 are mounted on the limbs 132, 134 of a slide 130 which embraces the left-hand end of the head 28 and is clamped thereto in adjusted position by a nut 146 and screw 148 ; the slide is adjustable vertically by a screw 136 having a large cap 138 for turning it. The channelling knife 26 is adjustably secured by screws 228 to a sector 222 having a tongue which engages an arcuate groove 220 in the limb 132 of the slide 130 ; the sector is secured in adjusted position, as determined by an adjustable member 232 having a stop surface 234, by screws 223. The grooving knife 30 is adjustably secured to the lower part 156 of a two-part slide 152 ; the two parts 154, 156 are detachably connected by a screw 158 and key-hole slot 160. The slide 152, guided by plates 162 on the limb 1.34 of the slide 130, can be raised to disengage the grooving knife by a toggle 168, 170 operated by a treadle 185 through a rod 186, bell-crank 190, 192, rod 198 and bell-crank 172, 170. The toggle is adjustable by a screw 184 and nuts 180, 182. Specification 315,812, [Class 31 (i)], also is referred to.

Abstract: 1275348 Pipe couplings HERMES-WERKE LEOPOLD HERRMANN 6 July 1970 [7 July 1969] 32711/70 Heading F2G [Also in Division H2] A socket for receiving a pipe end 1 includes a seal ring 4 made of an electrically insulating elastic material, a screw ring 3 which is separated from the seal ring 4 by a slip ring 5 and a split metal ring 6 which is of a less electropositive material than the slip ring 5. Such a pipe coupling is suitable for an underground pipe line carrying earth currents. The slip ring 5 is preferably made of zinc or magnesium and the metal ring 6 of iron or steel. The former acts as a sacrifice anode and the latter maintains an electrical connection with the pipe end 1. Hence an electrical contact is formed which prevents earth currents causing corrosion of the pipe end 1 by the formation of local cells.
