IPC: G01C11/00
Filed: 1969-04-09
Abstract: 1,253,703. Stereoscopic measuring. CARL ZEISS JENA VEB. April 9, 1969, No. 18228/69. Heading G1F. In a method of measuring an object stereoscopically an oscillation between a stereoscopic mark and a stereoscopic image of the object is introduced, the oscillation having a frequency f of 10 min<SP>-1</SP> # f # 50min<SP>-1</SP> and an amplitude A of ##/##A #10 ##/# where ## is the mean width resolving power of the eye and r is the angular magnification of the viewing system. The oscillation may include quarter period pauses at each reversal point. Two stereoscopic marks having a distance apart when viewed of 2A may be used. In Fig. 1, marks 8 and 9 on plates 6 and 7 combine when viewed stereoscopically to form a stereoscopic mark the depth of which may be varied by lateral movement of plate 7. The stereoscopic image of the object is oscillated by varying the lateral position of the image produced in eyepiece 5 using contra-rotating wedges 18, 19. The wedges may be rotated continuously Fig. 1, or backwards and forwards over a limited arc Fig. 2 (not shown). In an alternative embodiment an electrically driven pendulum Fig. 3 (not shown) oscillates a wedge across the ray path 0 1 -0 1 , or oscillates the plate 6.

Title: Improvements in or relating to apparatus for assembling the sheets or leaves of calandars, blocks, or the like
IPC: B65H39/042
Filed: 1939-06-23
Abstract: 526,795. Assembling sheets. SANDKAULEN, H. June 23, 1939, No. 18405. [Class 100 (i)] Sheets are assembled to form calendars &c.by feeding the sheets individually in succession from piles 1, 2, 3 by means of reciprocating feed rollers 5, and the feed rollers 21, 24 are timed so that the sheets arrive at the assembly point 4 without overlap. The rollers 21 are positively driven and the rollers 24 which are mounted in slots in levers 25 are operated by a series of staggered cams 30, 31, 32 and links 27, 28, 29, so that the sheets are timed to arrive in succession at the point 4. The feed rollers 5 are connected to a pair of feeding arms 7 which are reciprocated on slides 16 by lever- and-link mechanism by a cam on the shaft 33, and the rollers are mounted in slots in the arms 6 but are prevented from rotation by abutments 18 when moving towards the rollers 21, 24. The sheets are controlled by guides 20, 44, and if the sheet feed fails the machine is stopped by a feeler mechanism comprising a weighted lever 34 adjacent each pair of feed rollers, and a co-operating slot 43 in the sheet guide 44. The levers 34 are raised above the slots 43 once in each operation of the feed mechanism by means of abutment levers 36 operated by a bar 38 which is raised by a bellcrank lever 36 and a link 41, connected to a feeding arm 7, as the feed arms move to feed the sheets. When the bar 38 descends the levers 34 descend towards the guides 44, and if a sheet is absent the corresponding- lever 34 descends to a position indicated by dotted lines at the top of Fig. 1. This prevents a vertically reciprocating bar 46 from moving to its highest position, and consequent upon this a lever 54 is operated by a cam 56 so as to actuate a switch 61 for stopping the machine. The lever 54 can swing on a vertical pivot to bring a roller on it into the path of the cam 56. This is effected by a pivoted member 50 on the rod 46 which acts upon an inclined surface on a casing 51 to which the lever 54 is pivoted. Normally if the sheets are all present the bar rises to such a position that the lever 54 swings back to move the roller out of the path of the cam 56. The bar 46 is fitted with shoulders 49 which are engaged by the levers 34 to limit the rising movement of the bar when a sheet is missing. The sockets on the shoulders 49 are eccentric to the pivots of the levers 34. A bell-crank lever 62 normally held by a catch may be used to restore the parts to normal position after the feeler device has operated.

Abstract: 314,494. Associated Telephone & Telegraph Co., (Assignees of Pye, H. C.). June 28, 1928, [Convention date]. Tell-tale apparatus.-In a system for repeating at a distance the reading of a meter, the meter controls the frequencies of two oscillators which are arranged to produce beat oscillations of variable low frequency characteristic of the meter reading. As shown, the meter M controls the position of the movable vane C relatively to the fixed vanes C<1>, C<2> of a condenser to vary the relative oscillation frequencies of valve generators 1, 2 which co-operate to produce a low frequency beat which is characteristic of the position of the movable vane C. The oscillations are amplified in the valve 3 and are applied to line through a transformer T to produce indi. cations on a frequency meter IM which may be of the vibrating reed, moving coil or moving vane type. The line wires L', L<2> are connected to wipers W<1> - - W<4> which facilitate the selective connection of one of a number of meters with its corresponding indicator. The line wires may be utilized to transmit power, the output of the amplifier effecting modulation of a carrier current wave. The shape of the condenser plates may be varied to suit the requirements of calibration. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement (Fig. 1, (Cancelled) (not shown)) wherein the meter M controls the frequency of a single oscillator which co-operates with a generator of fixed frequency to produce the low frequency beat. This subject-matter does not appear in the Specification as accepted.

Abstract: 1470133 Separating seeds M B HAGNER and K L WENDT 6 May 1975 [17 May 1974] 18999/75 Heading B2H In a method of separating seeds which have started to germinate from non-germinating seeds, all the seeds 3 are carried on the surface of a liquid 2 and the seeds which have parts projecting down into the liquid are separated from the remaining seeds. The parts projecting down into the liquid may be acted upon by streams of liquid produced by means of a diaphragm pump 4 and a chamber 10 provided with a plurality of tubes 11 dipping into the liquid 2. The chamber 10 and pump 4 are filled with liquid so that operation of the pump produces alternating streams of liquid at the openings of the tubes 11. On the pump intake stroke these streams act on the downwardly projecting parts of those seeds which have germinated and pull these seeds beneath the surface. On the output stroke of the pump 4 these seeds will be forced away from the openings of the tubes 11 and, if they have a higher density than the liquid and were originally supported by the surface tension alone, will sink to the bottom where they are collected in a container 12. If the seeds have a density lower than that of the liquid, the tubes 11 are directed so that the seeds which have germinated are returned to a different part of the surface to that on which they originally floated. In another embodiment, a rotating brush is located just below the surface of the liquid, the germinating seeds catching on the brush bristles and being pulled below the surface. In a further embodiment, horizontal flows immediately beneath the surface of the liquid are used to separate and transport the germinating seeds laterally on the surface. Another method of separation may use a photo-electric cell to detect parts projecting from the seeds.
