Title: Connector for connecting cable conductors
IPC: B62J11/19
Filed: 1975-06-18
Abstract: 1481774 Cable connectors UNION SILS VAN DE LOO & CO 18 June 1975 [22 June 1974] 25974/75 Heading H2E A connector for connecting a conductor inside an insulating body to one or more further conductors outside the body comprises a contact insertable in the body and retained by a clamping member attachable to the body by detents to clamp the conductors against the contact and to grip the further conductor(s) against axial strain. A circular contact plate 36<SP>1</SP> is held in a recess in an insulating portion 31<SP>1</SP> of the bottom cap 30<SP>1</SP> of a cycle dynamo engaging the end of wire 35<SP>1</SP> forming the stator winding and the ends of wires 42<SP>1</SP>, 43<SP>1</SP> leading to the cycle lamps by an insulating clamping member 40<SP>1</SP> which latches in a bayonet or snap fashion on to holding members 37<SP>1</SP> of the cap 301. The plate 36<SP>1</SP> has teeth cutting into the wires. The wires extend through and are clamped by projections in a central bore of the clamping member 40<SP>1</SP>. In an alternative embodiment the contact member (3611, Fig. 8, not shown) is a hollow cylinder with the wires (42<SP>11</SP>, 43<SP>11</SP>) jammed between the inside surface of the cylinder and a central portion (4111) of the member (4011). In Figs. 2-5 (not shown) the wires are clamped between the clamping member (40) and a detachable portion (31) of the cap.

Title: Improvements in or relating to the production of printing formes
IPC: G03F3/08
Filed: 1958-08-13
Abstract: 893,655. Copying-by-scanning. HELL, R. Aug. 13, 1958 [Aug. 14, 1957], No. 26025/58. Class 40(3). The engraving of printing plates in accordance with signals generated by the photo-electric scanning of an original to be copied is controlled in such manner that the contrast in the region of abrupt changes in the tone of the original is increased. This is achieved by simultaneously scanning the original with two light spots, the first being the usual scanning spot I (Figs. 1 and 5) and the second a larger spot 2 (Figs. 1 and 5), the signals produced (when scanning across the demarcation line 3 between a dark portion 4 and a light portion 5 of the original) by the latter spot in photo-electric cell 11 (7, Fig. 2) being subtracted from the signals produced by light spot 1 in photoelectric cell 10 (6, Fig. 2) to derive a correction signal (8, Fig. 3) which is added to (or employed to multiply) the signals from photo-electric cell 10 to produce the signal 9 (Fig. 4) employed to control the engraving tool, The depths of penetration of the tool is thus reduced approaching the demarcation line 3 from the dark side 4 and results in a blacker copy whilst on leaving line 3 the depth of penetration increases for a short distance into the light portion 5 resulting in the production of a still lighter copy. The arrangement for processing the signals to produce the correction signal is shown in Fig. 5 where the output of the respective photo-electric cells 10, 11, rendered suitable for A.C. amplification by known means (not shown) is amplified by amplifiers 12, 13 and after gamma correction in devices 14, 15 and detection in 16, 17 is supplied to a subtraction circuit 18 to produce the signal 8 (Fig. 3). This signal is then supplied through serially arranged amplifiers 19, 20, gain controlled respectively by the detected signals from 16 and 17, to an amplitude limiter 21 and thence via a potentiometer 22 to an amplifier 24 in which it is combined with the signal output from amplifier 12. The combined signal from 24 is then supplied via a further amplitude limiter 25 to control the engraving tool of the plate engraving machine in known manner. The adjustment of the devices 14, 15, 21 and 25 for various contrast requirements is discussed. When the colour separation printing plates are being produced the arrangement described is applied only to the blue and black separations since these, mainly, determine the detail of the copy produced. Specifications 734,462 and 819,244 are referred to.

A copying lathe is provided with control means operated by a single feeler for longitudinal movement of a carriage and transverse movement of a tool-slide thereon, so that the feed of the tool may be regulated continuously in both directions. The lathe comprises a chuck 1, Fig. 1, and a tailstock 2 supporting a workpiece 13. An assembly of three tool-carriages for non- copying work is mounted in the lower part of the machine and a copying device 4 is positioned above the work. The copying device comprises a longitudinal carriage 5 moving on guides 6 driven by an hydraulic ram 7, the cylinder of which is fixed to the frame and the piston-rod attached to the carriage 5. The transverse tool-carrying slide 9 is movable on vertical guides on the carriage 5 and is moved by an hydraulic copying device 10 including a ram 16, Fig. 4, for moving the slide, the piston-rod 17 of which is fixed to the slide. The tool 12 may follow the contour of a template 14 mounted on the frame above the carriage 5. A feeler 20 being provided for scanning the template. The feeler is carried by a rocker arm 18, Fig. 3, the axis 19 of which lies in a plane parallel to the vertical plane through the lathe axis but inclined to the directions of longitudinal and transverse feed. The end of the rocker opposite the feeler carries an adjustable tappet 21 which operates the transverse feed distributing piston valve 43 through a ball 42. The latter is under control of an hydraulic member 74 which may be hand-adjusted and moves the ball sideways automatically to give a copying rough-cut, the ball being brought to the centre position for the final finish-copying cut. The piston valve 43 connects with a booster 45 and a distributing valve 49 for the longitudinal feed movement. Two electromagnetic valves 63, 69 are included in the control arrangement and thermostatic throttle valves 50, 51 provide for viscosity changes in the fluid system. The longitudinal slide 5 carries a rocker 30 which on contacting stops 32, 33, adjustable on a fixed part of the machine, stops or reverses the feed. Two arms on the rocker are connected by wires 37, 38, to operate a valve control lever 73. Exchangeable cam bars 41 may be clamped to a stationary part of the machine to operate a rocker 39 to give rapid longitudinal movements to the carriage 5. A lever 23 projects from the end of the copying device 10 on the tool-slide and a roller on its end is adapted to contact one of a series of stops 28 on an automatically indexible drum 26. The latter is mounted on the carriage 5 and the stops act to limit the downward movement of the tool-slide so that a number of automatic traverses for roughing may be taken prior to the final copying cuts. Switch gear on the drum conditions a control circuit for the electrically operated valves.
