Title: Apparatus for inserting workpieces in apertures in workpiece  holders
IPC: H05K13/04
Filed: 1971-11-08
Abstract: 1330196 Assembling force fits; making electrical components AMP Inc 8 Nov 1971 [18 Nov 1970] 51763/71 Headings B3A and B3U Apparatus for inserting a workpiece 148, 150, Fig. 10, into an aperture 194 in a holder 192 comprises a ram 42, Fig. 3, for inserting the workpiece into the aperture and means, e.g. a hammer and anvil 70, 158, Fig. 6, for compressing the workpiece prior to its insertion to produce an interference fit between the workpiece and the holder on insertion of the workpiece in the aperture. In operation the aperture 194 is positioned over a post 4 so that a tip 190 of a spring biased plunger 188 is partially received therein. A piston and cylinder assembly 17 is then actuated to move the ram 42 downwardly via a pivoted lever 26 and rods 22 and 38. A cam 41 associated with the rod 38 moves downwardly so that a roller 52 traverses the part 44 of the cam and pivots an arm 58 in an anticlockwise direction, Fig. 3, to advance the hammer 70 and a blade 98 horizontally towards the anvil 158. The blade 98 is mounted within a slot in the lower face of the hammer and has an enlarged end 100, Fig. 3, which is spring- biased against the rear end of the hammer so that the blade will follow the movement of the hammer towards the anvil. The tip 126 of the blade 98 moves between first and second workpieces in a feed 130, Fig. 6, and simultaneously the face 118 of the hammer strikes the portion 148 of the second workplace against the anvil 158 to form the portion 148 into an elliptical shape. During advancement of the tip 126, a tapered side wall 124 of the blade 98 progressively disengages the leading workpiece. Simultaneously advancement of a side wall 120 of the hammer causes a door 162 to pivot in an anticlockwise direction, Fig. 6, against the action of a spring 168 and allows the leading workpiece to become disengaged from the feed 130. The disengaged workpiece falls through a bore 180 in a collet 110 until the lip 150 of the workpiece engages tips 186 of fingers 184. As advancement of the rod 38 continues the roller 52 traverses a flat surface 46 of the cam 41 so as to retain the hammer and blade in the advanced position while the ram 42 enters the bore 180 and forces the workpiece into the aperture 194. The post 4 has a longitudinal slot 212, Fig. 10, so that the inserted workpiece can be removed from the post without the holder 192 being lifted. If the leading workpiece is not removed from the feed 130, the blade 98 cannot reach its fully advanced position and so does not actuate a switch which allows the operation of the apparatus to continue. In another embodiment the plunger 188 is replaced by a spring-biased ball which engages holes in a template, the latter being clamped to the holder.

Title: Data searching system
Inventor: EVANS JAMES RICHARD
IPC: G06F3/06
Filed: 1970-11-02
Abstract: 1279056 Data storage INTERNATIONAL BUSINESS MACHINES CORP 2 Nov 1970 [12 Nov 1969] 51955/70 Heading G4C A data searching system compares a record transferred from a random access storage device (e.g. magnetic disc) with search parameters from a stored table which includes start address and field length information, the comparison results being stored, stored indications of predetermined combinations of selected search parameters controlling logic means for performing a series of tests upon the comparison results to determine if the combinations have been satisfied, there being means for transferring to an output a record which satisfies at least one of the combinations. Data transfer between any of a plurality of disc stores and a main store is via a (disc) storage control unit and a CPU in series. In the storage control unit, as a serialby-bit record arrives from the disc it is converted to parallel form in a shift register and inserted in a core buffer, and also supplied serial-by-bit to comparators for comparison with upper and lower limits (see below). The buffer also includes a sequence of three table entries each specifying upper and lower limits between which the value of field of a record or records should lie, the start address of the field in the record, the number of bytes in the field and three logic control bits. As the record arrives from the disc, each table entry in turn is used as follows. The start address is incremented by the address starting at which the record will be stored in the buffer, the result being compared with the address register of the buffer so that on equality a compare latch is set. This enables a counter preset with the " number of bytes " field to be decremented as each byte is stored in the buffer. The compare latch also enables comparison of the field with the upper and lower limits, and if it is between them a result latch respective to the table entry is set. The compare latch is reset when the counter reaches zero (end of field). When all the table entries have been thus used, logic circuitry checks the result latches corresponding to table entries whose first logic control bits are 1 to see if all are set. If so the record is read from the buffer to the main store (via the CPU), but if not similar checking is performed using the second logic control bits, followed by read out or use of the third logic control bits similarly. Transfer in the other direction (main store to disc) is also possible. Extra upper and lower limit comparators may be provided to deal with synonyms.

Title: Specimen analysis with ion and electron beams
IPC: G01N23/225
Filed: 1974-12-02
Abstract: 1457975 Scanning electron microscope ETEC CORP 2 Dec 1974 [17 Dec 1973] 52097/74 Heading H4F Specimens 15, Fig. 1, are analysed by producing a C.R.T. display representative thereof having improved definition. The specimen 15 is mounted on a stage 14 in a vacuum chamber 10 and bombarded by a primary ion beam 28 from source 26. The current of secondary ions emitted from the specimen as a result of bombardment is modulated by a scanning electron beam, emanating from a scanning electron microscope (SEM) 46, in accordance with the mass to charge ratio of the secondary ions emanating from the constituent elements of the specimen. A quadrupole mass filter 33 is used to transmit ions having a given mass : charge ratio. Controls 21 to 25 are provided for positioning stage 14 within the chamber 10 which is evacuated by pump 12. In operation the filter 33 is operated in a spectral mode whereby ions of all mass : charge ratios in a predetermined range are passed by cyclic variation of the narrow transmission range of the filter over the range, while the C.R.T. scan is controlled by the filter control unit 34 to provide a mass : charge ratio vs. beam intensity plot, Fig. 2, on the C.R.T., giving the relative distribution of the various elements in the specimen 15, Fig. 1. The narrow transmission window of the filter is then fixed to pass ions of mass : charge ratio within the range of mass : charge ratios of those ions originating from the element of interest. The control of the C.R.T. scan is switched 50 to a sweep generator 48 which causes synchronous raster scanning of the C.R.T. 42 and the S.E.M. 46 while the C.R.T. beam intensity is modulated by the output of the filter, to produce a display showing the areas of high concentration of elements of interest. The filter may be operated in a combined mode wherein the narrow window is shifted at a slow rate relative to the raster rate to provide a composite picture of the distribution of two or more elements. The various control signals may be converted to digital form and recorded or stored in a computer memory.

Abstract: 1336728 Multi-colour photographic silver halide material AGFA GEVAERT A G 19 Nov 1970 [22 Nov 1969] 54982/70 Heading G2C A multi-layered colour photographic material for the production of colour images which consist of a yellow, a magenta and a cyan partial image, comprises at least one double layer comprising a highly sensitive silver halide emulsion layer and a less sensitive silver halide emulsion layer in which double layer a partial image is to be produced, both emulsion layers containing a colour-forming coupler for the particular partial image, in which the highly sensitive emulsion layer is more sensitive by from 0À1 to 0À6 log I.t units than the less-sensitive emulsion layer and contains a colour-forming coupler for the particular partial image which couples by from 2 to 20 times more rapidly than the colourforming coupler in the less sensitive emulsion layer. The highly sensitive emuslion layer is preferably further from the support than the less sensitive emulsion layer. Other layers may be interposed between the less sensitive and the more highly sensitive emulsion layer of a double layer. The ratio of coupler to silver may be different in the two layers of the double layer. The same coupler may be present in both layers of a double layer but incorporated in different ways in order to give the different coupling rates. Incorporation in an oil-former gives a slower coupling rate than incorporation as an aqueous solution. Coloured colour forming couplers may be used and may be present in a layer either alone or together with a colourless coupler having the same or at least a similar coupling rate. The material has a very high sensitivity and gives colour images of great sharpness and little graininess.
