Abstract: 1,200,161. Selective punching apparatus. D.T.R. DEVELOPMENT CO. Ltd. 4 Aug., 1967 [4 May, 1966], No. 19750/66. Heading B4B. A punched-tape data recorder comprises a number of punches 21 arranged to co-operate with holes formed in a die 18 and having sensing ends which are engaged by coding wheels 33 each having a number of peripheral faces and rotatable in order to selectively present any one of the faces to the sensing end of the punches, each face being provided with a respective recess to accommodate the sensing end of each punch which it is not to engage. The punches 21 reciprocate in guides 19, 20 mounted above the die 18 and, together with the latter, are secured to uprights 15 mounted on a base 12. A platform 24 for a document is slidable on pins 22, 23 extending from the guide 20 and is provided with rods 28 which, via bales (29, Fig. 9) maintains all the punches in a raised position. The coding wheels 33 are mounted on a shaft 32 secured to a plate 31A which is connected to side members 31 slidable on the uprights 15; the coding wheels are each coupled to setting wheels 35 via sleeves 34. The side members are raised and lowered in order to effect the punching stroke by means of cams 54, 55 engaging followers 52, 53 on the side members, the cam being mounted on a shaft 16 rotatable by means of a handle 17. In order to permit rotation of the handle a pivoted lever 43 is moved by means of a start button 45 thereby moving a pin (46, Fig. 10) out of the path of movement of a notch (47) formed in a plate 48 secured to the shaft 16. The tape for receiving the punched holes is fed over the die 18 by means of sprockets 72, 76 rotated during the latter part of rotational movement of the shaft 16 by means of a Geneva-and-gear mechanism (62, 65, 66, 69, Fig. 12). When the tape on the supply spool (78, Fig. 1) is used up a lever 81, Fig. 3, engages a notch (82, Fig. 10) in the start button-rod (44) thereby preventing operation of the machine. The machine is also prevented from operation if one of the setting wheels 35 is incorrectly set, by means of detent levers 38 which, if not engaged correctly in notches (37, Fig. 10) cause a catch 42 to engage with the lever 43 thereby preventing its movement.

Abstract: 517,022. Latch handles. WITHERIDGE, A. J., and HALLDRON, C. R. July 7, 1938, No. 20092. [Class 44] To allow a latch handle 3, shown as of lever form, to be reversible for right or left hand use, a member 8 mounted on and rotatable with the handle shank 2 has a lug 9 co-operating with a stop 10 which is resilient so that it may, when desired, be depressed to let the lug 9 pass. The lug may thus be disposed to co-operate with either side of the stop. As described stop 10 is of blade-spring form held between lugs 11 on the rear recessed face of an escutcheon plate 1 in which the handle shank is rotatably mounted, and spaced from plate 1 so that it may be manually depressed below the path of lug 9. One or other limb of a U-spring 12 bears against the face of lug 9 remote from stop 10 to hold the lug and stop normally in contact. A sliding catch 14 is provided to prevent actuation of the handle by engagement in one or other of two recesses 15 in a member 6 on the handle boss. Rotation of the handle is limited by a projection, not shown, on the inner face of member 6, working in an annular groove interrupted by a segmental stop and formed in the adjacent front face of plate 1. The latch operating spindle 2a is secured within the handle as shown.

Title: Improvements relating to receivers for electrical pulses
IPC: G01S1/02
Filed: 1943-12-01
Abstract: 581,698. Radiolocation; photo-electric apparatus. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. Dec. 1, 1943, No. 20114. [Classes 40 (iii) and 40 (v)] The presence of pulse signals in noise, which are presented as deflections of a trace on a cathode-ray tube screen, is detected by observation of the variation in intensity of the trace line produced on the screen by limitation of the deflecting signals. Fig. 2 represents the defections produced by random noise, curve C showing the relationship between amplitude and probability of occurrence of the noise pulses also indicates the distribution of intensity of illumination in the ordinate direction. If all signals above a given amplitude (say alphaL) are limited, all the intensity of light previously distributed above this amplitude is now concentrated to produce a trace line, the intensity of which increases as (alphaL decreases, becoming maximum when alphaL is equal to - #. Curves D show the variation of intensity Ib of this trace as the limiting amplitude (either positive or negative) is decreased to zero. In Fig. 5, the entire upper portion of the noise pattern is limited and at point A, with no signal pulse present the intensity of the trace is indicated by Io. At point 13 the effect of a pulse signal is shown, the noise pattern being lifted by alphap, the pulse amplitude, so that a greater amount of noise is limited, producing a resultant trace intensity of Ip. If the limiter had operated on signals of the opposite sign, as illustrated in Fig. 4 (not shown), the trace intensity would have been decreased by the pulse signal. The limiter employed may comprise a simple biassed diode across the load resistance of a pentode valve feeding signals to the vertical deflecting plates of the C.R. tube. Two limiters operating in opposite sense may be employed with a double beam oscilloscope to produce parallel traces, the intensity of one being increased and of the other decreased by a pulse, to provide additional visual contrast. The intensity of the trace on the cathode-ray tube may be observed by a photo-electric cell in combination with a slotted mask, Fig. 8 (not shown), and other slotted mask, spiral slot or Nipkow disc which scans the trace, the output from the photo-electric cell being amplified and applied to a second cathode-ray tube to give an indication corresponding to a pulse signal, on a suitable time base. The invention is also stated to be applicable to radiolocation systems in which the frequency of a transmitted continuous wave is adjusted to produce a desired phase relationship between transmitted and reflected waves which results in an indication on a cathode-ray tube.

Title: Improvements in or relating to electron microscopes and testing electron lenses
IPC: A01K97/11
Filed: 1955-07-12
Abstract: 781,815. Electron lenses. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 12, 1955 [July 15, 1954], No. 20132/55. Class 39(1). An electron lens is correctly focused, in an electron microscope, or the errors of a lens are measured, by rapidly varying the direction of a ray cone 1 emanating from an object point and so apparently widening the cone, and measuring an A.C. component due to fluctuation of the image edge over an area 10 of the screen 11. The angle of incidence of the rays from source 2 on the object 6 are varied electrostatically or electromagnetically in planes 12, 13 as in Specification 660,787. Screen 11 may be fluorescent as in a microscope, and area 10 projected optically on to an electron multiplier, or area 10 may be a slot 17 backed by a separate fluorescent screen 21, Fig. 2, which is associated with an electron multiplier 23. An aluminium layer 24 reflects light from screen 21 and intercepts light from screen 11. In an electron microscope, focusing is achieved when the A.C. component vanishes. In lens testing, e.g., for determining astigmatism, the rays incident on the object may trace a circle and the focal planes are found at which the A.C. components in two perpendicular directions vanish. The measuring area may be rotated, or with two measuring areas at right angles, the two components may be measured simultaneously. An alternative method is described in which the incident rays trace two linear oscillations at an angle of 45 degrees. The A.C. components are measured at two areas parallel to the linear oscillations. Adverse effects of changing lens power or electron velocity are said to be avoided.

A development of the direction finder described in Specification 902,473 and comprising, for finding the azimuth and elevation angles of incidence α 1 , E 1  and α 2 , E 2  of two (N) equal frequency signals. four (2N) aerials (possibly Adcock type) 1, 2, 3 and 4 arranged rectangularly in the X, y co-ordinate plane as shown in Fig. 1 and respectively receiving signals:- where u 1  = k cos E 1  . cos α 1 , U 2  = k cos E 2 . cos z 2  v 1  = k cos E 1  sin α 1 , v 2  = k cos E 2  . sin α 2  Dividing signal U 1  by each of the other signals in turn, and taking Real (R) and Imaginary (I) parts: The right halves of the six equations contain six unknowns: u 1 , u 2 , v 1 , v 2 , A and #, thus by determining the left hand halves of the equations six simultaneous equations may be formed to give the six unknowns. Since the output of aerial 1 is always used, this is permanently passed via one channel 5 of a two channel receiver to a rectifier 8, to give /U 1 / and to one of the inputs on each of phase discriminators 12, 13, 14. The second channel 6 of the receiver is used to feed the outputs of the aerials 2, 3, and 4 respectively in cyclic sequence, to rectifier 9 and discriminator 12, to rectifier 10 and discriminator 13 and to rectifier 11 and discriminator 14. Ganged cyclic switches 7, 15 and 22 perform this function. Ratio deriving means 16, 17 and 18 are respectively fed with /U 1 / and /U 2 /, /U 1 / and /U 3 /, and /U 1 / and /U 4 /, to respectively produce the ratios Since these appear cyclically they are fed to stores 19, 20 and 21 respectively. Discriminators 12, 13, 14 respectively produce outputs representing (# 1 -# 2 ), (# 1 -# 3 ) and (# 1 -# 4 ) which are fed to stores 23, 24, and 25. The six stores are read simultaneously into a computer 26, which solves the six equations (1)-(6). Since # 1  is given by tan α 1 , = v 1 /u 1 , an indication of α 1 , and α 2  can be produced by feeding the signals from the computer, representing v 1  and u 1 , or v 2  and u 2  to the respective orthogonal deflection plates of a C.R.T. The slope of the resulting line trace indicating α 1  or α 2 . Equations can be used to determine the elevation angles of incidence E 1  and E 2 . The computer may be analogue but is preferably digital. One rectifier and one discriminator may serve instead of the three each shown if they are placed before the switches 15 and 22. To overcome any possible differences in the characteristics of channels 5 and 6 they may be rapidly switched over to produce an averaging output.
