Abstract: 791,311. Optical objectives. NAKKEN, T. H. March 19, 1954 [March 26, 1953], No. 8057/54. Class 97(1) A photographic objective comprises a front negative lens, a rear collecting element and intermediate optical elements for substantially eliminating all normal aberrations in which the final intermediate image framed by the other elements is "seen" by the rear element at an apparent size at least 1.75 times smaller than that observed from the "equivalent viewpoint" of the objective in the real scene. Such an arrangement is stated to produce an enhanced stereoscopic effect in the final image. The theoretical basis of the invention is discussed at length in the Specification. In Fig. 2, eyes 11a, 12a viewing an object 13a have respectively extreme directions of vision 14, 17 which meet at a point 18 defined as the "equivalent monocular viewpoint". Fig. 15 illustrates an eye 45 viewing an object 48 through a negative lens 46. Rays 49, 50, define the extreme rays reaching the eye 45 and to receive such rays in the absence of the lens 46 the eye 45 would have to be placed at the point 51 defined as the "equivalent viewpoint" of lens and eye for the particular object. By regarding each lens surface following the front negative lens as an eye, it is stated that an "equivalent viewpoint" of the objective for a particular object can be found. An example is referred to comprising a negative lens spaced in front of a Cooke triplet objective.

Abstract: 497,988. Machinery guards. LOVELL MANUFACTURING CO. March 16, 1938, No. 8117. Convention date, March 17, 1937. [Class 80 (iv)] The top plate 14 of a wringer takes the thrust of the spring 11 and is held at one end by quick-release trip mechanism operated by bars 39, one of which is provided at each side of the machine. A latch 19, Fig. 2, pivoted at 22 to the plate 14 has lugs 23 adapted to engage slots 17 in a stile 2, Fig. 5. In the set position, Fig. 6, the latch is held because a trip plate 30 is held by a finger 40a on the plate engaging a shoulder 40 on a cross-piece 37 connecting the bars 39. When a bar is moved the finger is brought opposite one of two slots 41, and if the inclination of the surface 24 of the lugs 23 is such that the equilibrium is unstable, release takes place ; if not, further movement of the bar brings one of two cam surfaces 42 on the member 37 against the finger and forcibly moves the plate 30 into release position. The left-hand end of the top 14 then rises under the influence of the spring 11 and the shoulders 15 and 16 at the other end are freed at the same time. The plate 30 is supported on a shelf 34 carried by the stile, a lug 32 on the plate passing into an aperture 33 in the shelf.

Title: Aiming devices
IPC: F41G3/06
Filed: 1977-02-25
Abstract: In order to point the line of sight at the target irrespective of the position of the firearm (19), the transmitting and receiving channel of the electro-optical range finder (20) is located in a predetermined position relative to the firearm (19). A servo control device (16, 6) is used for aligning the range finder (20) and the firearm (19) parallel to the line of sight of the observation telescope (14). The aiming device produces co-ordination of the command signal for the range measurement with signals which supply information on the deviation of the alignment of the range finder (20) from the alignment of the line of sight. The command signal is passed to the range measuring device (20) only when the deviation signals supply the information that the deviation is at least approximately zero. The advantages are particularly evident when driving vehicles fitted with weapons over rough terrain. <IMAGE>

Abstract: 1513083 Magnetic storage arrangements TEXAS INSTRUMENTS Inc 2 March 1976 [3 March 1975] 08273/76 Heading H3B In a magnetic bubble storage system comprising, for example, a magnetic film 58, Fig. 5, with a major loop 60 and plural minor loops 62-68 along which bubbles are propagated and are transferred between for data storage, writing and readout, the functions of bubble generation, stepwise positioning and detection is determined by a timing control system in which a read only digital memory has a plurality of output lines coupled to the bubble storage system to provide the required timing control of the various system functions. Fig. 1 shows schematically a bubble storage system comprising a bubble chip 10 in which such functions as bubble propagation by an in-plane drive field 12. detection by a detector 14, and bubble generation, replication and annihilation by function drivers 16, is programmed by a timing control digital memory 20 driven by a 3À2 MHz clock 22. A memory controller 18 driven by a 100 KHz clock from the timing control digital memory enables the drive field, detector and function drivers. The timing control digital memory 20 and a portion of the function drivers 16 is shown in greater detail in Fig. 2, in which the 3À2 KHz clock drives an 8 bit binary counter 26 and controls 8 bit batches 28, 29. The binary counter scans two 32 x 8 read only digital memories 30, 31 to produce an output pulse on a lead D 0 -D 15  whenever a "one" is encountered during the scanning sequence, the length of the pulse being determined by the number of "ones" in immediate succession. More than one output pulse may be produced on a lead, for example D7, duting a scanning cycle of 10Á secs. These output pulses are applied to two 8 bit latches 29, 29 which are enabled by the 3À2 MHz clock pulse outside the access time of the memory. From the latches function pulses are applied under the control of enable signals from the memory controller to the detector, function drivers and the in-plane drive field. A typical enabling circuit in the function driver is shown in Fig. 2, in which a bubble generator function pulse GENP from latch 28 is applied to the bubble chip through an AND gate having a 50 KHz clock pulse input and an input ENGEN from the memory controller.

Filed: 1972-02-24
Abstract: 1367856 Card reader INTERNATIONAL BUSINESS MACHINES CORP 24 Feb 1972 [4 March 1971] 8528/72 Heading G4M  A punched card which may also carry printed data is fed through a reader by driven rolls 19, 21, 25, 29 and respective pressure rolls 20, 24, 28, 30. Roll 25 is coupled to a toothed emitter wheel producing 16 pulses per column pitch. A light source 37, a fibre optic conductor 38 and a photo transistor 39 detect the end of a card and are arranged so that when a signal is issued the first column centre is half a column pitch from the reader. Each column is read in parallel and each hole is detected by a phototransistor 53 and its signal is amplified and fed to a register 57. Pulses from the emitter wheel are fed via an AND gate 58 enabled by phototransistor 39 at the trailing edge of the card and AND gate 61 to a counter. A decoder produces output pulses on counts 5, 6, 9, 10 which are symmetrical about the nominal centre of the data hole. At these pulses the data from OR gate 55 is entered into a respective stage of register 57. Stages A, B feed AND gate 66, C, D feed AND gate 65 and all four stages feed OR gate 68. The inverse of stages A, D feed AND gates 73, 72 respectively. If at least three stages carry a " 1 " the data is accepted as a " 1 ". If the A stage only is zero then a late timing signal issues indicating that the leading edge of the hole occurred after the number 5 pulse. If the D stage only is zero then an early timing signal issues. If both AND gates 65, 66 have zero outputs and a " 1 " issues from OR gate 68 then a read check signal is produced. If the printed data is to be read the OMR format is activated and reflected signals are received by photodetectors 46 and fed via amplifier 47 to comparators 48, 49 which determine when an 80% reduction and a 60% reduction in reflected light intensities occur. A mark producing no outputs from the comparators is considered an erase, from both comparators a valid mark and from the 60% reduction only, an error condition. The two signals are stored in stages A, B of register 57.
