Title: Crimping press
IPC: H01R43/048
Filed: 1973-05-01
Abstract: 1376877 Jointing by stamping; making electrical connections AMP Inc 1 May 1973 [24 May 1972] 20614/73 Addition to 1211666 Headings B3A and B3Q  A press for crimping terminals on a carrier strip to electrical leads comprises means for feeding the carrier strip which means is pivotally movable laterally of the feed path away from the crimping dies when they are closed so as to pull the carrier strip free of the crimped terminal between the dies. The press-ram 56, Fig. 5, carrying dies 84, 86 for crimping the wire and insulation is lowered by a cam 40 operated by a pneumatic cylinder 48. A pin 58 at the top of the ram engages a slot 62 in a lever 64 turning the lever the end 70 of which engages and lowers a slide 234 having a cam surface 254 for engaging a member 256 on the feeding mechanism 140 so as to turn the mechanism about its pivot 150 and free the terminal. The slide also has a lateral shoulder 246 for lowering a cam-slide 252 the cam 266 on which operates a valve (280), Fig. 1 (not shown), for supplying compressed-air to the bottom of a cylinder 222 so as to raise a spring-returned piston-rod 224. A head 226 on the rod bears on a second shoulder 238 on the slide 234 which it raises as a pivoted pawl 214 on the head turns a feed wheel 184. Reverse operation of the cylinder 48, withdrawing cam 40, permits the rising slide 234 to return the lever 64 and thus raise the ram 56. The ram may be lifted manually by a lever 90, Fig. 2, having a knurled knob 100 and a pin 98 insertable in retaining holes 108. A pin 104, Fig. 3, in the lever 90 intermediate its ends has an abutment 102 for raising the ram and passes through slots 116, 196 in a member 114 carrying a positioning stop 110 for the lead 14 and a member 192 carrying a strip hold-down 198. Thus lifting the lever raises the ram 56, stop 110 and hold-down 198, against a biasing spring 208. A screw 72, Fig. 2, on the cam 40 operates a microswitch 76 at each end of its stroke, one of the switches ensuring that the ram presses down correctly and the other preventing continued cycling. Another microswitch 78 is operated by the lever 90, interrupting the electrical supply when the lever is raised. The feed mechanism includes a toothed wheel 180 for engaging slots (190), Fig. 7 (not shown), in the carrier strip 122, the wheel being coupled to the wheel 186 by a uni-directional clutch 174, Fig. 3. A block 144 carrying the feed mechanism is biased upwardly against a stop screw 164 by a spring 152 and is turned about the pivot 150 to free the carrier strip.  The press is started by a foot-operated switch, the upward stroke of feed rod 224 being ended and the rod returned by spring action when projection 246 raises the cam-slide 252 for releasing the valve (280).

Abstract: 1330202 Radiographic apparatus MEDINOVA AB 19 April 1971 [9 Feb 1970 20 Aug 1970] 19 April 1971 21328/72 Heading H5R In radiographic apparatus which includes a filter 7, Fig. 4 or 7, having a non-uniform absorption for the ionizing radiation from the source 1, whereby to permit partial compensation for the varying thickness of the body 3 being radiographed, such that the exposure of the recording medium is kept within its exposure latitude over the whole of the image area, the correct positioning of the filter with respect to source 1 and the body 3 is facilitated by the provision of a visible light source arranged such that the beam therefrom, after having been affected by the filter, is directed towards the object as if it proceeded from the source 1. As shown in Fig. 7, in which the light from source 8 is reflected by the mirror 9, and the beam of ionizing radiation is defined by the diaphragm 11, the light beam may originate at the side of the filter 7 opposite to that at which the body 3 is located, to produce a shadow image of the filter, which may be intensified and sharpened by the provision of lenses 21 adjacent the outer edges of the filter. The shadows of the filter 7 and the diaphragm 11  may be distinguished by employing for diaphragm 11 a material which is transparent to visible light, e.g. lead glass, and which is either stained or provided with an optical screen pattern, the filter 7 being either optically opaque or, if transparent, stained a different colour, or provided with a different optical screen pattern. Alternatively, as in Fig. 4, the light source 13, mounted in a tube 16, may be positioned on the object side of the filter, the light being reflected from a reflecting layer 15 coated on the undersurface of the filter, which may, for intensifying and sharpening the shadow image, be formed as a collection of concave mirrors (Fig. 9, not shown), or be provided with superimposed lenses (Fig. 8, not shown). To further facilitate the positioning of the filter 7 the latter may be provided with optically opaque or non-reflecting markings corresponding to isoabsorption lines (Figs. 5 and 6, not shown). A filter 7 which is optically transparent may, as shown in Fig. 3, be combined with material 12a and 12b which has the same optical refractive index as material 7, but is transparent to the ionizing radiation, to prevent distortion of the light beam in its passage through the filter. The filter is preferably of a rare earth metal.

Abstract: 1,032,224. Transistor amplifier circuits. PHILCO CORPORATION. May 22, 1964 [May 23, 1963], No. 21332/64. Heading H3T. A transistor amplifier comprises three D.C. coupled common emitter stages in cascade, the last being of opposite conductivity type to the other two and negative feedback being applied from the output collector to the input base. In Fig. 1 (not shown) the feedback is through series resistors 42, 44, the junction point of which is partly by-passed to earth through a capacitor 48. Additional feedback is provided by a resistor from the output collector to the second base and stability is increased as a result of the change of resistance with temperature of the output transformer winding. An alternative circuit (Fig. 2, not shown) differs mainly in the absence of the feedback path 30 and by the provision of a feedback resistor 50 shunting resistors 42, 44 to provide some A.C. feedback.
