Title: Telecommunications exchange systems
IPC: H04Q3/54
Filed: 1971-09-20
Abstract: 1350111 Automatic exchange systems SIEMENS AG 20 Sept 1971 [23 Sept 1970] 43671/71 Heading H4K In a telecommunications system in which each of a plurality of pieces of equipment are connectable to a common circuit, in which a line associated with the path is connected to a potential source capable of enabling a single relay, and in which each piece of equipment has an individual seizure circuit associated therewith, which when its piece of equipment requires access to the common circuit repeatedly connects a relay to the multi-conductor line, a response of the relay indicating that the path is free at that instant, each seizure circuit has provision to alter the duration for which its said relay is connected to the multi-conductor line. In that the interval between connection attempts is not altered the chance of successful seizure varies with this duration and can be discretely varied by setting relay contacts in accordance with the degree of urgency of the connection. If for example the common circuit is a central control unit and one of the pieces of equipment is an auxiliary control unit then that auxiliary control unit may have priority of access over the other pieces of equipment and a relay contact in its seizure circuit may be set such that whenever the auxiliary control unit requires access to the common control unit it connects its relay to the multi-conductor line until that relay responds.

Abstract: 910,534. Reservoir pens. FABRICA ITALIANA MATITE LYRA S. a. r. L. Dec. 31, 1959 [Jan. 20, 1959], No. 44450/59. Class 146 (3). The writing unit of a retractable ball-point pen is removable for replacement through a lateral slot in the barrel. The onepiece barrel 1 of the pen is open at both ends and adjacent to the rear end has two diametricallyopposed lateral slots 2, 3, the slot 2 being the wider and the longer of the two. The writing unit 4 is made of flexible material and is engaged at its rear end in a recess in a plunger 5 which is formed integrally with a pocket clip 6. The clip 6 projects through the slot 2 and at its junction with the plunger presents an abutment 8 which in the retracted position of the writing unit is held in contact with the rear end of the slot 2 by a retracting spring 10. On the opposite side of the plunger to the clip are formed a tooth 7 which projects through the slot 3 and an abutment 9. In order to project the unit 4 to writing position the operator presses downwards and inwards on a knurled portion 6<SP>1</SP> of the clip until the abutment 9 on the plunger engages with the rear end of the slot 3, in which position it is maintained by the spring 10. Inward pressure on the tooth 7 releases the abutment 9 and allows the parts to reassume the Fig. 1 position. The writing unit 4 is replaced when exhausted by pulling the clip 6 downwards and outwards until the whole of the plunger 5 passes out through the slot 2, this being allowed by the flexibility of the unit 4. The plunger 5 is then pulled rearwards to extract the unit 4 from the barrel 1. When a new writing unit has been mounted in the plunger the above operation is reversed and the pen reassembled.

Abstract: 1,019,173. Fluid pressure servomotor systems. AUDCO Ltd. Nov. 5, 1964 [Nov.13, 1963], No. 44824/63. Heading G3P. A valve such as a cargo valve in an oil tanker vessel is actuated by a hydraulic servopiston 6, the fig. (not shown) under the control of a valve 7 subject to the opposed forces of springs 8, 9. The spring 8 is compressed by a cam 11 driven by the servopiston and the spring 9 by a bellows 13 subject to the output of a reducing valve 15 with a calibrated handwheel 16 so that any error between the actual position of the servopiston and the desired positions as determined by the pressure applied to the bellows 13 results in a corrective movement by the servopiston. Whenever an error exists a band 19 allows leakage through a variable restriction 17 from the conduit 14 between the valve 15 and bellows 13 and this condition is indicated by a flow responsive device 18. Instead of the band 19 a spring-loaded spool 23 subject to the pressures on the two sides of the servopiston 6 may be provided to vent the conduit 14 in the event of inequality of the pressures. The band 19 or spool 23 may alternatively be arranged to provide the leakage only when no error exists. An alternative indicator arrangement employs a valve 25 which prevents or permits leakage when the servopiston 6 reaches either end of its travel.

Abstract: 1480630 Electronic raster-scanned image analysis CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 31 Oct 1974 [2 Nov 1973] 47222/74 Heading G1A Apparatus for electronic image analysis, wherein TV scan video and line-synchronizing signals 11 are available, comprises a generator 9 of a frequency above the line frequency, dividing the raster into elements having a fixed position relative to each other in successive lines; a discriminator 2 for selecting, according to selectable criteria, objects to be evaluated, its output connected to decision-logic circuit 6, having a synchronizing control connection from generator 9 via line 19; storage 30 for a preselected digital value; switch means 31 linking discriminator 2 having first and second states reflecting object presence and absence respectively and having an output characterized by said digital value when switch 31 is in the second state, means 35 subtracting one digit from each raster-digit signal and being connected to the output of logic circuit 6 whenever switch 31 is in the first state, and a comparator 38 pre-set for a guide-value raster digit signal beyond which limit subtraction ceases and upon receiving which it gives an output and AND gate 40 provides an output for particle evaluation; an n-1 bit delay storage device 20 for n raster elements per line with connections 25 and 27. In the method of analysis a digital value is assigned to each raster element, and each raster element within the boundaries of an object is projected in at least one pre-selected direction  upon raster elements in consecutive lines, changing its digital value by one digit position per line until reaching the guide-value, so that the object is length discriminated in a sloping direction, and that only raster elements having said guide-value are used to define the object to be evaluated. The guide-value may be zero. Oscillator 9 and divider 10 are stopped at the end of each line by synchronizing pulses 11 and started at the beginning of the next. Divider 10 supplies 8Hz pulses on lines 12 and 13, of phase difference 180 degrees. Pulses from divider 15 control switch 14 to make pulses on 12 and 13 act for even- and odd-number lines respectively. Thus the even-number line raster elements are displaced by half-element spacings from the odd-number line elements. Delay means 36 is connected for alternate lines so that projection continues along a line, whose slope depends upon the amount of delay. The slope is from top right to bottom left if delay means 37 is not connected and from top left to bottom right if it is. Devices 36 and 37 are selectively controlled by signals on 23 and 24. There is a synchronizing control connection from line 19 to lines 23 and 24. A plurality of decision-logic circuits may be employed in series e.g. 46 and 49 Fig. 4 (not shown) for successive projections in different directions, (54, 55, 56) Figs. 5a-5e (not shown).
