Title: Apparatus for controlling the entry of information into a storage arrangement
IPC: H03K21/00
Filed: 1966-02-15
Abstract: 1,139,077. Pulse counter control systems; timing. KOZPONTI FIZIKAI KUTATO INTEZET. 15 Feb., 1966 [18 Feb., 1965], No. 6651/66. Heading G4A. A system for controlling the entry of information into a storage arrangement having a plurality of storage channels includes an address register for selecting successive storage channels in response to successive pulses of a pulse series applied to the register; gating means coupled to said register to control the application of said pulse series thereto and/or to control the obtaining of overflow signals therefrom such that successive overflow signals are obtainable in response to different numbers of pulses of said pulse series; counting means coupled to receive the overflow signals obtained from said register and to produce a signal for enabling entry of information into said storage arrangement when a preselected count is registered; and means for setting said register, gating means and counting means into a predetermined start condition for responding to said pulse series so that said enabling signal from said counter is produced after a delay in time following the setting operation. As described, in a multi-channel timespectrum analyser for recording the distribution of events (e.g. neutron arrivals) in time with provision for a variable period of delay before the recording is started, the channel selection register is used for controlling the period of delay in such a way that overlap of successive adjacent recording periods may be obtained, as illustrated in Fig. 1 (not shown). In a preferred embodiment, Fig. 8, an address register/ counter 7 is provided, successive states of which during a recording period select channels of the analyser, not shown. On receiving a start signal u, the register 7 and two counters 17, 19 adopt preset conditions and a gating means 9 is set to open AND-gates 16, 20 and close AND-gates 15, 18 whereby clock pulses i are gated into an intermediate stage of the register 7. Overflow signals k from the register 7 increment the counter 19 to a preset value whereupon a control signal q to gating means 9 reverses the settings of the gates 15, 16, 18, 20. Clock pulses i are now gated to the lowest order stage of register 7 and overflow signals k to the counter 17 which is thereby incremented to a further preset value. A control signal p issued when this value is reached causes a memory control gate signal h to be generated which initiates the recording of detector signals in the memory at addresses selected by the register as it is incremented once more through its counting range. The next overflow signal k causes a recording end signal f to be generated. Other arrangements are described with reference to Figs. 5-7 (not shown) in which the clock signals i and/or the overflow signals k are applied to/received from successively different stages of the register 7 through input/output gating systems and only one counter (other than register 7) is necessary.

Title: Improvements in null-type radiation analysis systems
IPC: G01J1/24
Filed: 1959-02-26
Abstract: 882,806. Photo-electric spectrum analysis. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. Feb. 26, 1959 [March 31, 1958], No. 6669/59. Class 40(3). The invention relates to a null-type spectrum analysis system by which the absorption spectrum of a sample can be determined which has means for increasing the indications produced by weak absorption bands so that the existence of such bands can be more readily detected. The apparatus used consists of means deriving a measuring beam, passing through the sample, and a reference beam from the same source, means applying the two beams alternately to a thermocouple, and means adjusting an attenuator in the reference beam controlled by the thermocouple to equalize the intensity of the two beams falling on the cell. According to the invention a second attenuator with a different characteristic to the first is inserted in the measuring beam and is coupled to the first attenuator so as to move therewith. Fig. 1 shows such apparatus schematically, 1 being the source, 4 the sample, and M the measuring beam. V is the reference beam and the two beams are directed alternately by rotating chopper disc 6 to a Littrow spectroscope 14, 15, 16, 17 whose mirror 17 can be tilted to scan the spectrum past the outlet slit 19. A thermocouple 20 receives the energy passing through the slit 19 and provides a signal which is amplified and demodulated to control the movement of attenuators 24 and 25 in the reference and measuring beams respectively in such a way as to maintain the signal constant and unfluctuating. The attenuators may consist of diaphragms whose characteristics are as indicated diagrammatically in Fig. 2. It is explained mathematically and with reference to Fig. 3 (not shown) that this considerably increases the sensitivity to weak absorption bands. The attenuators are coupled to a recording instrument and this may make a record on paper moved in accordance with the tilting of mirror 17. Complete spectra can thus be readily determined. In the example given, weak absorption bands cause a recorder deviation ten times as large in proportion to those caused by strong bands.

Title: Method of producing workpieces of complicated shape from light metal powder
IPC: C22C1/04
Filed: 1955-03-14
Abstract: Biasing bushes are formed (see Group XXII) from powder of an alloy consisting of: Sn 7 per cent; Cu 1 per cent; Ni 0.5 per cent: Al the remainder.ALSO:Work pieces of complicated shapes are made from powder in flake form obtained by mechanically comminuting, e.g. by pounding or grinding, shavings of light metal of specific gravity less than 5, by hot or cold pressing the powder into bodies of cylindrical, prismatic or parallelepipic shape with or without sintering and bringing the body into final shape by forging, drop forging, extrusion and rolling.  The sintering, when performed, is preferably done simultaneously with the pressing and the body may be finally machined to shape.  The light metal shavings should be cleaned before comminution so that the grease content of the powder is less than 1 per cent.  An alloy powder may be used or the powder may be a mixture of the components of the alloy.  In one example aluminium alloy, aluminium and silicon flake powders are mixed and pressed at 2 tons centimetre square to a cylinder. The cylindrical body was annealed at 460 DEG C. for one hour and then drop forged to form pistons.  In another example flake powder of aluminium bronze was cold pressed to form a blank which was then hot pressed with simultaneous sintering. The blank was then hot dropped forged to form a bearing bush.  In a further example aluminium silicon flake powder mixed with silicon powder not in flake form was cold pressed into a billet which was extruded at 460 DEG C.  The extruded body was drop forged into bearing blanks.
