Title: Frequency divider circuit arrangement
IPC: H03K3/2885
Filed: 1975-05-23
Abstract: 1463651 Bi-stable circuit PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 May 1975 [27 May 1974] 22666/75 Heading H3T A frequency divider substantially as shown has two bi-stables I, II each having cross coupled transistors T 1 , T 2  and T 3 , T 4  which respectively have a common emitter circuit connected via a current source T 7 , T 8  to a respective point of constant potential-E with the current sources being controllable in opposite phases by an input signal A, A; the collectors of the first bi-stable being connected to the respective collectors of the second bi-stable each by the collector-base path of an individual auxiliary transistors T 5 , T 6  whose emitters are connected to a point of constant potential via a common current-determining element R6 and with a coupling resistor R7, R8 included between the collector and base of each of the auxiliary transistors T 5 , T 6 . There may be a further resistor between the base of the auxiliary transistors T 5 , T 6  and the collector of the second bistable to which it is connected, indicated by the dotted lines to provide two resistors and not a single variable resistor. In operation there are two differential amplifiers one T 7 , T 8  driving the emitter circuits of each bi-stable I, II, the other T 5 , T 6  drive the collector circuits of the first bi-stable I only. If the input A is high, current I 1  flows via T 7  to R 5  and energizes bi-stable I which assumes a first master state M 1 , this sets bi-stable II to a first slave state S, via R 7 , R 8 ; however, the differential amplifier T 5 , T 6  is then driven by the bi-stable II to counteract the master state M 1  of bi-stable I (negative feedback) the current I 2  is R 6  compensates partly for the current I 1  and reducing the difference voltage between the outputs 1, 2 of bi-stable I. When A goes low, the slave state of II gradually, while remaining the same, becomes the master state M 1  and causes bi-stable I to change to the opposite (slave) state S 0 . The next transition at A from low to high causes the slave state S 0  of bi-stable I while remaining the same, to become the master state Mo and the state M 1  of bi-stable II is changed to the opposite (slave) state So via R 7 , R 8 . Thus bi-stable I changes over for every transition from high to low at A and the input frequency is halved. For the circuit to operate at high frequencies, typically 1250 kHz, the delay caused by the internal base resistors of T 5 , T 6  is compensated by altering the phase of the input to this differential amplifier with respect to the operating phases of the bi-stables I, II by tapping the bases down the coupling resistors R 7 , R 8  effectively to add a series resistance between the base of T 5 , T 6  and collectors of T 4 , T 3 . In a modification (not shown) the common current determining resistor R 6  can be replaced by separate resistors each connecting an emitter of the auxilary transistors T 5 , T 6  to the constant potential.

Title: A rotating radio beacon with announcement of the bearing
IPC: G01S1/46
Filed: 1951-10-05
Abstract: 750,213. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Oct. 5, 1951 [Oct. 13, 1950], No. 23201/51. Class 40 (7). The invention relates tc radio beacons of the type ir which an equi-signal guide line is defined and rotated in azimuth. at a low fre quency, the radiated energy being modulated by a signa indicative of the instantane. ous direction of the guide line and the guide line being defined by the intersection of two radiation patterns produced alternately by switching the phase of energy fed to the system at an audio frequency. According to the invention each pattern is arranged to have one minimum only, the two minima differing in direction by less than 90 degrees, and the patterns are so shaped as to substantially coincide except near the two minima. It is preferred to make the patterns near cardiod in shape as shown at A and B. The patterns A and B intersect at S, defining a guide line, and are approximately coincident except over the range of angles including the minima. The beacon aerial system may comprise four outer radiators at the corners of a square and a central radiator, the two sets of diagonally opposite outer radiators having their individual feeds in antiphase while the two sets are fed in quadrature. The phase of the centre radiator is chosen to equal that of one of the others. The pattern shape shown can be produced by energizing the radiators of one set at unit intensity, those of the other set with #3 units, and the central radiator with 2 units intensity (Fig. 2, not shown). The patterns can be rotated mechanically by turning the whole array, and alternation of the two patterns is achueved by switching the phase of the energy supplied to the central radiator through an angle of, say, 30 degrees. At a receiving position an audio modulation signal caused by the pattern switching is obtained at strength on either side of the guide line along which the bearing indentifying signal is heard. In directions making a considerable angle with the guide course, the identifying signal may also be heard but no audio signal is obtained over a wide angle. The correct guide line is thus easily identified.

Title: Improvements in and relating to combination padlocks
IPC: E05B37/10
Filed: 1944-11-23
Abstract: 588,930. Combination padlocks. YALE & TOWNE MANUFACTURING CO. No. 23, 1944, No. 23333. Convention date, Nov. 27, 1943. [Class 44] A padlock of the combination tumbler type comprising a rotatable bolt, a series of rotatable tumblers having gatings, a fence adapted to enter the gatings, and means whereby the fence, when in the gatings, is locked for rotation with the bolt, the fence when out of the gatings being free of the bolt which is then rotatable independently of the fence. The invention is shown applied to a padlock of the kind in which the locking mechanism may be actuated under the control of a key or through the combination tumblers. The bolt 17, Fig. 2, comprises a circular plate having a peripheral flange 40, adapted to engage locking slots in a shackle 11, and a central post 16 carrying a clutch member 14 and engaging one end of a spring 44 which normally holds the bolt in the locked position. A dial 22 carrying a tumbler operator 20 may be rotated freely on the bolt for operation of the bolt through the tumblers and the fence, or may be coupled to the clutch member, by key operation of a plug 13 mounted within the dial, for direct rotation of the bolt. Tumblers 23, having gatings 22, are rotatably mounted on a member 25 carried on the post 16 and prevented from rotating by an arm 26 engaging the lock casing. The fence 60, which is adapted to rotate with and to slide radially on the bolt, is provided with a pin 65, a dispenser lug 66 and a post 68. A fixed back plate 32 is provided with a control lug 33 and carries a pivoted, spring-loaded disperser 34. The circular plate portion of the bolt located within the fence and back plate is provided with slots 55, 57, Fig. 5, for receiving the members 33, 34, 65 and 66. In the locked position the lug 33 abuts the pin 65 and the disperser 34 abuts the disperser lug 66, thus preventing rotation of the fence in either direction. When the dial is operated to align the gatings 22, a gating 24 in the tumbler operator 20 and the post 68, the post is moved radially by a spring 69, Fig. 4, acting on the post. The post then slides into the gatings and the members 65 and 66 are disengaged from the members 33 and 34 respectively.The fence is now freed from the back plate and locked to the bolt. The dial may now be rotated to move the bolt against the action of the spring 44 until the notches 46 and 47 in the peripheral flange of the bolt becomes aligned with the shackle, which-is then ejected from the casing by a spring-loaded plunger 48. If the shackle is re-inserted in the casing the spring returns the bolt to the locked position and during the movement the tail of the disperser, acting on the disperser lug, slides the fence out of engagement with the tumblers. U.S.A. Specification 2,154,660 is referred to.

Abstract: 746,946. Photographic reversal images. KODAK, Ltd. Sept. 10, 1953 [Sept. 17, 1952], No. 23391/52. Class 98 (2). Photographic reversal images are formed by migratory transfer by contacting, in the presence of a silver halide solvent, an exposed and developed silver halide emulsion layer which contains developer, with a receiving layer containing a dispersion of zinc sulphide, selenide or telluride in an amount sufficient to react with only a part of the silver halide diffusing thereinto. The silver sulphide precipitated acts as development nuclei for the remainder of the silver halide diffusing thereinto. A diffusible developer may be contained in the silver halide emulsion layer, development being effected by treatment with an alkaline solution and the wet emulsion layer being then contacted with the receiving layer. The silver halide solvent may be contained in the receiving layer. In a modification the image-receiving layer and the silver halide emulsion layer are part of the same material. Thus, a paper support may be impregnated with the zinc compound and then coated with an unhardened silver halide emulsion layer. After development and treatment with a silver halide solvent or development with a developer containing a silver halide solvent, the emulsion is washed off. The entire operation may be carried out in the camera by rolling the exposed light-sensitive layer into contact with the receiving support with a bead of viscous developer in between, containing for example hydroquinone, sodium sulphite and a silver halide solvent such as ethanolamine. Specifications 614,155, 654,631 and 746,174 are referred to.

A spring-pressed brake roller 47 may arrest the ticket on a plate at exit 15. A ticket entering slot 14 actuates photoelectric switch S1 to start the conveyers. Rollers 20, 21, 22 are synchronously driven by motor M1 to feed the ticket to band conveyer 18, a gravity pawl clutch on roller 22 allowing the ticket to accelerate without tearing. Transfer of the ticket to rollers 37, 38, 39, synchronously driven by motor M3, is by a similarly clutched roller 37 to prevent buckling. Switch S2 turns the conveyers off as the ticket passes to the exit slot. If a ticket is not removed from exit 15 the conveyers stop so that the order of tickets inserted into the gate is not confused. Reference has been directed by the Comptroller to Specification 1,181,554.
