Patent GB-2152697-A (GB)
Title: Improvements in or relating to scanning optical microscopes
Inventor: BREARLEY MARTIN ALAN
IPC: G01N21/55
Filed: 1984-10-24
Abstract: A scanning optical microscope has a laser L1 passing a parallel beam through beam splitter O3 to be focussed by lens L2 on specimen S1. Radiation reflected from S1 is directed by splitter O3 to photodiode detector d1 whose output passes to a display unit having a visible element (e.g. CRT spot) whose intensity varies with the signal. The lens mount O5 is moved rapidly to give a line scan and the specimen support moved slowly to produce a frame scan; transducers supply signals to drive the visible element to correspond to the scan movement. The parallel beam enables specimen and scanner to be remote from the laser, allowing examination of highly radioactive specimens. A phase retarder can be inserted to enable examination of the specimen using polarised light. An automatic focussing arrangement is described. <IMAGE>

The core shaft 3 has a hexagonal power-transfer boss 3a and is axially movable in the support shaft (5) between a first position in which the boss 3a engages in a hexagonal socket 5b in the support shaft (5) to transmit rotation from the core shaft 3 to the speed reducer mechanism 14 and a second position in which the boss 3a is out of driving engagement with the socket 5b. <IMAGE>
Patent GB-845071-A (GB)
Abstract: 845,071. Cash registers. NATIONAL CASH REGISTER CO. Nov. 28, 1958 [Jan. 8, 1958], No. 38406/58. Class 106 (1). A key-set cash register has a control member, which in the embodiment described controls a repeat mechanism, the control member being movable in one direction or the other on depression of any one of certain control keys depending on whether or not an amount key has been depressed and being arranged in certain circumstances and in either of its two operative positions to block the machine release mechanism if a control key is held either partially or fully depressed at the end of an operation. The invention is applied to a machine substantially the same as that disclosed in Specification 792,975 in which a repeat operation takes place on depression of any one of certain control keys when no amount keys are depressed. In these circumstances, a plate 269, Fig. 2, is cammed downwardly by the depressed control key and rocks arms 314, 313 counter-clockwise. On the other hand, depression of an amount key raises a finger 310 and the arms 313, 314 are rocked clockwise by a spring and lower the plate 269 which is then, on depression of a control key, cammed further in that direction. If at the end of a repeat operation a control key is held depressed, the arms 313, 314 will be held in their counterclockwise position even though an amount key is depressed and operation of the machine must be prevented. For this purpose, the arm 313 is coupled to a cam-plate 464, Fig. 10, controlling a plate 460 with a slot 459 which cooperates with an ear 456 pivoted on a lever 452 rockable with the machine release shaft 139. The ear 456 is rocked on the lever 452 by a second notched plate 471, Fig. 11, positioned together with the finger 310 under the control of the amount and certain other keys. The arrangement is such that if the arm 313 is held in its repeat position although the finger 310 has been raised by depression of an amount key, the ear 456 is aligned with the undersurface of the plate 460 and not with the slot 459. This results in the blocking of the release shaft 139. If one of the control keys is held depressed towards the end of a non-repeat operation to prevent the normal return of the plate 269 and arm 313 to the repeat position, a lever 484, Fig. 10, is able to rock clockwise from the position shown and to move over a lug 485 of the lever 452, as shown in Fig. 17, thus blocking the release shaft 139 again. This indicates to the operator that it is necessary to set up an amount on the keys as the operator might otherwise attempt to perform a repeat operation by depression of a control key only. The machine is released under these conditions by operation of the key-release lever 115 which rocks the lever 484 to ineffective position. Reference has been directed by the Comptroller to Specification 792,975.
