Abstract: 714,709. Reverse-gear control. CLEVELAND PNEUMATIC TOOL CO. Oct. 30, 1951 [Oct. 30, 1950], No. 25370/51. Class 80 (2) [Also in Groups XXXVII and XXXVIII] The gear changing mechanism of a boat engine is moved to "forward," " neutral or "reverse" under the control of a selector switch 34. Movement of the switch to any position F, N, R, energizes a motor brake release magnet 40 in series with either the " forward " or " reverse " windings of a motor 16 dependent on the direction of movement of the switch. The motor is thereby driven, in the appropriate sense, to rock the gear shift lever 14 to a corresponding position, through gearing 20 and a screw and nut 18, 22, e.g. as disclosed in Specification 569,245. The motor circuit is made through one of the brushes 66, 68, 70 on the arm 64 which reciprocates with the travelling nut 22 and the appropriate fixed contact plate 58 or 60. If the " forward " or " reverse " brush is operative the motor runs until the operative brush passes off the end of the associated contact plate. If the neutral" brush is operative the motor runs until the brush reaches the gap 72. In each case the motor circuit is broken and braked to a standstill by de-energization of the brake release magnet 40 when the gear shift lever 14 has reached the corresponding position. The motor 16, the brake mechanism 40, 48 and the switching means 66, 68, 70, 58, 60 are all mounted on the gear casing 20 which is pivoted at 30 to the framework.

Abstract: 1,135,309. Telegraphy. SIEMENS A.G. 2 June, 1967 [3 June, 1966], No. 25470/67. Heading H4P. A telegraph exchange includes a group of trunk-line circuits which are seized successively, and has means operative only after seizure of all the line circuits in the group for delaying the renewed seizure of any line circuit which has become free: the delay gives time for the connection to break down. When a subscriber calls, a central control unit ZSt connects itself to the subscriber and to a free line circuit of the group Uel-Uen, and the subscriber is connected to the selected line circuit. Suppose all the line circuits are free. Relays F1-Fn, FB, and FW are energized, their contacts being in the positions shown. ZSt gives a signal on TA when any line circuit is free. If a line circuit, e.g. Uel, is seized its relay F1 is de-energized, and cannot be energized again until fw reverses. This will not occur until all the line circuits Uel-Uen have been seized, whereat FB and FW drop so allowing FG to be energized via any line circuit now free and energizing the associated relay F. A timing unit ZTG provides pulses in cyclic succession on outputs GL1-GL4, pulses on any one output being spaced by sufficient time to allow a connection to breakdown. Suppose that prior to a pulse on GL2 all the line circuits had been seized and Uel had become free so that F1 was energized. When the pulse occurs on GL2 relay G2 is energized, so energizing GS. Contact gs2 prevents any line circuit which subsequently becomes free from energizing its relay F until GS drops. At the next pulse on GL2, relay FB is energized. Hence FW is energized and FG drops; fg2 opens and GS drops. Unit ZSt prevents any line circuit from being seized while FW is de-energized, i.e. during the break-down monitoring time.

An optical assembly comprises a main lens (36) Fig. 5 (not shown) in a carriage 38 movable along an optical path, a supplemental lens (40) in a mount 42 pivotally mounted on the carriage 38 and having cam followers 78 and 80 which engage cams 82 and 84 to move the supplemental lens (40) into or out of the optical path. There may also be a second supplemental lens (44) in a mount 46 pivotally mounted on the carriage and having a cam follower 86 which engages a cam 88, and each of the mounts 42 and 46 may have a spring urging it out of the optical path. When the carriage 38 is at the extreme left hand end of the casing 60, with threaded abutment rod on the carriage in contact with abutment member 112, both the supplemental lenses are out of the optical path. If the carriage is moved along guide rods 62 and 64 to a central position, with the rod 106 in contact with movable abutment member 122, the cam 82 brings the lens (40) into the optical path; if the carriage is moved further to the right, so that the rod 106 contacts abutment member 118, the cam 84 removes the lens (40) from the optical path, while the cam 88 moves the lens (44) into the optical path. Movement of the carriage 38 is effected by means of an air cylinder 128 having a piston (130) secured to the carriage by means of an arm 132. The position of the carriage is determined by relays under the control of an operator, and these, together with trip switches actuated by the carriage, control the supply of air to the cylinder 128. The circuitry for this is described.
