Title: Detection of faults on surfaces
IPC: G01N21/89
Filed: 1971-11-30
Abstract: 1366369 Counting faults in moving webs FERRANTI Ltd 30 Nov 1972 [30 Nov 1971] 55626/71 Heading G4D [Also in Division G3] In an arrangement for counting surface faults in webs of paper, plastics, steel, &c., a beam of light is repetitively scanned across the surface of the web 11 and light emanating from the surface is collected, e.g. by a photomultiplier 16, and applied to means 25 whereby a fault signal is produced each time there is a change in the collected light level. The invention provides a means whereby the fault signals are counted only while the scanning beam is directed on to the web. Near the beginning 17 of each scan the beam falls on a detector 19 shown as a photodiode thus producing a pulse; this pulse C, which can be adjustable to allow for various sized webs, triggers a generator 24 which produces a pulse D which extends from just before the earliest time that the beam could encounter the edge of the sheet to just after the latest. The collector 16 output is differentiated at 25 to provide the fault pulses which are applied to a counter 31. Only large fault pulses (i.e. due to the beam passing the edge of the web) pass a comparator 26 to trigger a circuit 27 arranged to deliver a signal E continuously before a trigger pulse and until 80 m.secs. after the arrival of a pulse. Signals D, E and the large fault pulse are applied to the three inputs of an AND gate 28 which thus delivers an 80 m.sec. pulse as the beam passes the edge of the web only if the edge occurs in an acceptable position. After a delay 29 to avoid a spurious count from the rest of the large fault pulse, the 80 m.sec. pulse enables the counter 31 which then counts subsequent fault pulses for a period dependent upon the known width of the web. In a modification (Fig. 3, not shown) further timing pulses are generated before and after pulse D and are employed to open further gates which control servo units to correct the position of the web if its edge does not occur during pulse D; a count can then be made during the next scan. Where the web is likely to vary in width a similar arrangement for detecting its trailing edge and stopping the counter may be provided. Or, alternatively, (Fig. 5, not shown) two separate scanning arrangments, each of which employs a multifacetted mirror 15, may be arranged so that each detects one edge as a leading edge.

Title: System for retrieving data from a store
IPC: H03M11/18
Filed: 1971-12-01
Abstract: 1369012 Data retrieval system INTERNATIONAL BUSINESS MACHINES CORP 1 Dec 1971 [31 Dec 1970] 55705/71 Heading G4H A system for addressing a predetermined location of a store comprises a keyboard having a plurality of areas each having at least one key (not shown) and means 21-97 to generate, on actuation of a key, a byte 37 representing a weighted key code and a byte 99 (one of bits 90-93, and bits 94, 95) identifying the area in which the actuated key is located. The bytes are fed to means responsive thereto (not shown) to generate an address of a predetermined store location corresponding to the actuated key. The areas correspond to, e.g. alphanumeric characters 20, commands 40 (e.g. invoking subroutines), keyboard functions 60 (e.g. carriage return), and to expansion of the character range (for language change); additional data (from ancillary components) is indicated at 94, 95. Depression of a key closes the corresponding switch (see Fig. 2) which is connected to a diode array so as to set appropriate latches L to provide the outputs. Depression of a key 20 provides an alphanumeric output at 37 and a "1" at 91 (since there is a "0" at 90, 92, 93) whereas a key 40 would give rise to a "1" at 90 as well as an output 37 which identifies the particular command key which has been actuated, and similarly for keys 60 and 80. In each case an interrupt signal 36 is obtained from an OR gate 35: this indicates to a processor that data is available and should be acquired for further processing and causes the processor to delay the program while it samples first byte 99 and then byte 37. The former byte indicates the keyboard area so that the two pieces of information combined can determine the appropriate storage address required for subsequent operations. Different system codes may be allocated to the same physical key by changing a key cap and the data in a specific core location, thus allowing a larger number of key configurations and codes with the same keyboard. Specific byte configurations may be composed by actuating selected keys, thus permitting manual entry of program modification, of diagnostic information, and of whole programs. The above system may be modified to incorporate the typamatic function, wherein a given data entry is repetitively performed until the key is released.

Title: Process for the hydrogenation of cycloalkane hydroperoxides

IPC: B01J23/96
Filed: 1969-11-20
Abstract: 1,221,629. Cycloalkanols; cycloalkanones. RHONE-POULENC S.A. 20 Nov., 1969 [21 Nov., 1968], No. 56964/69. Heading C2C. The invention relates to the production of cycloalkanols and cycloalkanones by the continuous hydrogenation of cycloalkane hydroperoxides in cycloalkane solution with the aid of a catalyst comprising a Group VIII metal deposited on an inert support. According to the invention, the process is so effected that the hydroperoxide solution first contacts a part of the support containing sufficient catalyst to permit substantially complete hydrogenation and then contacts a second part of the support containing no catalyst or insufficient catalyst. It is found that the catalyst migrates during the process from the first part of the support to the second part and that, by periodically interchanging the two parts, the process may be continued practically indefinitely. An example describes the hydrogenation of cyclohexane hydroperoxide in apparatus in which the support is arranged in three sections each separated by a distributer plate, the first or catalyst-rich section becoming the third section after an appropriate time.

Abstract: 1276418 Digital transmission systems; active filters WESTERN ELECTRIC CO Inc 10 Dec 1970 [11 Dec 1969] 58587/70 Headings H3U and H4P A frequency shift receiver employs a converter which provides at each sampling instant a multi-bit number indicative of the sign of the instantaneous amplitude of the frequency. The numbers are passed to a digital filter which provides signals to the receiver output circuitry. As described the filter is time shared between a number n of input f.s.k. channels, the receiver being distributed to a like number of outputs. Each channel is connected to a respective sampling unit (110), the units being sampled simultaneously at rate f greater than the highest received frequency. The state of the sample- (positive or negative) triggers a bi-stable store. The n bi-stables are read out sequentially to a number generator (112). The generator providesa preset number or its twos complement, dependent on the state of the bi-stable being scanned. The series of numbers is fed to a digital band pass filter (301) whose output passes to tuned digital filters (318, 319) tuned to the shift frequencies. The outputs of the tuned filters are rectified in respective digital rectifiers (303) whose outputs are subtracted. The resulting signal passes via a digital low pass filter (305) to a circuit (113) which senses. the sign bit of the numbers from the filter. The sign bits are passed by a distributer (114) to n bi-stable stores (115) providing the n binary receiver outputs.
