Abstract: 1,146,953. Road traffic detectors; counting apparatus. SIEMENS A.G. 30 March, 1967 [30 March, 1966], No. 14525/67. Headings G4D and G4Q. In a traffic detector arrangement of the type having electrical conductors D arranged in an area passed by the traffic such that changes in capacitance, inductance or mutual inductance are used to control indicating and/or counting devices Z, an additional conductor p is included which can be short-circuited by a switch k so as to affect the conductors D and simulate the passage of a vehicle. This tests whether the detector is operating correctly. By pressing a test key T, at a control centre Ze relay K is energized via t 2 ; this operates contacts k so that the additional loop p modifies the inductance of the detector loop D. When the test key is pressed a voltage is applied to a delayed alarm relay A. If the detector is functioning correctly the change in inductance when the additional loop is short-circuited, is detected and relay V is energized. Contact v opens and the 'delayed alarm relay A does not operate. If there is a fault, relay V is not energized and relay A operates a bell W. The key T can be operated repetitively at predetermined time intervals by a programme generator.

Title: Apparatus for use in the automatic recognition of written characters
IPC: G06V30/164
Filed: 1964-04-09
Abstract: 1,003,817. Automatic character reading. SIEMENS & HALSKE A.G. April 9, 1964 [April 11, 1963], No. 14616/64. Heading G4R. In an automatic character reading apparatus the characters are scanned in a series of vertical strokes to produce black or white signals on a terminal f, Fig. 1, which are applied to a trigger VS and to And gate UG and Neither- Nor gate WN. The output from the trigger forms the other inputs and is the same as signal f, slightly delayed. Gate UG responds to a sequence of two black signals and gate WN to a sequence of two white signals. The output of gate UG is passed through Or gate OG and blocking gate SG to shift register GS. This holds exactly one vertical scan and it has a recirculating loop via Or gate OG. The character may be written and have an irregularity as shown on the underside of the line in Fig. 2. The vertical lines n - 2 to n + 1 indicate successive scans and the horizontal lines m - 1 to m + 2 indicate the delay imposed by the trigger VS. The signals derived from the scanning are as shown in Fig. 3. The effect of the irregularity is removed by the circuit to produce signals as shown in Fig. 4. In scan n - 2 the gate UG responds when the signal and the output of trigger VS are both black, i.e. down to line m + 2, to enter a black signal via Or gate OG and blocking gate SG to register GS. This signal recirculates and is only modified in succeeding scans at the point where the signal and the trigger output are both white. Gate WN then responds and closes gate SG. The output at g is therefore modified to effect the removal of the irregularity. Spurious marks and gaps are also removed if they do not exceed the delay of trigger VS. A delayed output may be taken from the righthand side of store GS.

Title: Improvements in Apparatus for Grading or Separating Fibres according to their Length.
IPC: D01G15/02
Filed: 1917-10-10
Abstract: 119,693. Fine Cotton Spinners' & Doublers' Association, and Balls, W. L. Oct. 10, 1917. Fibres, separating and sorting.-Apparatus for grading cotton or other fibres in accordance with their length comprises a separating-device, which takes a tuft of fibres and feeds it forward gradually, and is traversed relatively to a collecting-device so that the fibres as they are fed forward are deposited in accordance with their length at different points on the collecting-device, the shortest being deposited first and the longest last, The apparatus may be designed for use in grading samples of fibres in the testing-room or for use commercially in the production of slivers or roves, the fibres of which are all of approximately equal length or of a length between certain desired limits. In a machine of the latter type, the separating-device comprises a series of feed rollers A, Fig. 5, which receive the sliver or lap Band pass it forward to delivery rollers C. The fibres are taken from the rollers C by a doffing-comb E and laid upon the collecting-mechanism, which consists of a series of card-covered flats G. The delivery rollers A are mounted on a cam-controlled frame whereby they are moved towards and away from the delivery rollers C in order that tufts of fibres may be detached by those rollers. The rotation of the rollers C and the movements of the flats G are so timed that fibres within a given range of lengths are always deposited upon a given section of the flats. A number of laps B, Fig. 1, with feed and delivery rollers and doffing-combs are mounted on a rotating frame so as to deposit the fibres in four ranges upon the four series of flats G, from which they are doffed by combs g and the slivers collected in coilers H. In an arrangement suitable for use in the testing-room, a separating-head arranged as above described may be fed with a sample or tuft of fibres placed in a tray or shoot and may rotate within a fixed collecting-device comprising an annular frame covered internally with plush or card clothing. In another simple form, a bunch of fibres is fed by hand to rollers traversing in front of a stationary or revolving plush-covered roller. The collecting-device may be traversed in place of the separating-device. If additional precision is desired, an additional traverse may be imparted alternating with the sorting traverse in which the end of the fibres is not quite pushed into the nip of the delivery rollers, so that any misplaced fibres may be seized and removed. According to the Provisional Specification, pneumatic means may be employed in connexion with the collecting- device.

Abstract: 760,749. Automatic phase control. RADIO CORPORATION OF AMERICA. May 20, 1954 [June 16, 1953], No. 14886/54. Class 38 (4). [Also in Group XL (c)] A single amplifier device which is connected as an oscillator, the phase of which is controlled by a reference oscillation, also provides means for combining the two oscillations to produce a control voltage, depending on their phase difference, which varies a reactive characteristic of the device to control the oscillator frequency. The invention is described with reference to a colour television receiver in which a local subcarrier oscillator is controlled by the incoming signals. In one embodiment, bursts of colour subcarrier gated by the horizontal sync. pulses at 13 are applied to the collector of a point contact transistor through the transformer 38, 40. The emitter circuit comprises the tank circuit 26 tuned to the colour subcarrier frequency. The base electrode circuit to earth includes resistors 35, 36, their junction being connected to the centre tapping of inductor 27 and capacitor 37 which together with resistor 36 provide an integrating circuit having a time constant comparable with the burst recurrence period. The D.C. bias developed across circuit 36, 37 depends on the relative phases of the generated and reference oscillations and varies the effective reactance of the base circuit, which is in parallel with tuned circuit 26, until synchronism is attained. The subcarrier output is taken from terminals 32. In a second embodiment, a junction type transistor is used and the correcting voltage, developed in the collector circuit, is fed back to the base circuit, Fig. 3 (not shown). A further embodiment employs a triode in a Hartley oscillator circuit, a correcting voltage being fed back from the anode to the grid circuit through a neon tube to control the input reactance, Fig. 4 (not shown).
