Title: Improvements in or relating to electric relays
IPC: B61L1/18
Filed: 1931-12-10
Abstract: 389,580. Electromagnetic switches. GENERAL RAILWAY SIGNAL CO., Rochester, . New York, U.S.A.-(Assignees of Field,< >O. S.; 89, Inglewood Drive, Rochester, New York, U.S.A.) Dec. 10, 1931, No. 34303. Convention date, Dec. 10, 1930. [Class 38 (v)] In order that a relay used, for example in a railway signalling circuit, may quickly release its armature if the voltage supplied to the maintaining winding is greatly reduced, the circuit of this winding includes an asymmetrical conductor such as a dry surface rectifier which offers a low resistance to electric current when the voltage impressed thereon exceeds a predetermined value and a relatively high resistance when the impressed voltage falls below this value. As shown in the Figure, the holding winding of the relay PR is connected across the insulated rail section 1 fed by a battery 3 in series with a rectifier AR, the winding circuit including a contact arm 4 of a relay SR, the energizing circuit of which is completed by the armature 8 of the relay PR. When the voltage supplied is greatly reduced as by the entry of a train into the left-hand end of the section, the consequent increase of resistance of the rectifier AR in the maintaining circuit ensures a rapid fall of current in this circuit and consequently a rapid release of the .armature 8. The release of the armature 8 produces the deenergization of the relay SR, its contact arm 4 engaging a back contact and placing windings 11, 10 of the. relay PR and the rectifier AR in series across the rails 1. Upon the track becoming occupied the inter.-rail potential at the entrance end rises to its normal value which is above the critical value for the rectifier AR so that a rapid pick-up of the armature takes place, the winding 11 being cut out of the maintaining circuit by the subsequent operation of relay SR. In a modification the rectifier AR is connected in the lead 13 so that it is out out of the pick-up circuit, or in a further modification the rectifier may be arranged to be shunted around the pick-up circuit.

Abstract: 429,197. Selectors responsive to code signals. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and ROBINSON, E., Ericsson Telephone Works, Beeston, Notting- ham. Dec. 7, 1933, No. 34402. [Class 40 (iv)] A contact-making device, adapted to close its contacts only after the receipt of a predetermined number of impulses and designed to have the dimensions of an ordinary telephone relay, comprises an auxiliary magnet 13 which must be energized continuously during the receipt of impulses by the stepping magnet 2, the auxiliary magnet being mounted in the prolongation of the axis of the stepping magnet and preferably with its axis at right angles thereto. The armature 23 of magnet 13 when operated associates a holding pawl 25 with ratchet 14 and permits stepping pawl 10 to engage with the ratchet. The last tooth of the ratchet is deeper than the remainder so that after the predetermined number of steps the pawl 10 is able to engage with notch 27 to tilt a pivoted member 26 which through a link 28 with a T-head 29 operates the contacts 4. The pawl 10 and ratchet wheel 14 have adjustable back stops. Wiring connections are made to tags 31, the leads to magnet 13 being taken through flexible tubes 32. A small non-magnetic pin 35 prevents magnetic leakage between armatures 7, 23. The assembly is such that magnet 2 or magnet 13 with ratchet 14 and associated parts may be readily removed as units.

Patent GB-927276-A (GB)
Title: Airplane instruments
IPC: B64D43/00
Filed: 1959-10-15
Abstract: 927,276. Aircraft instrumentation. SAFE FLIGHT INSTRUMENT CORPORATION. Oct. 15, 1959 [Oct. 20, 1958], No. 34983/59. Class 40 (1). [Also in Group XL (c)] Signals which are functions respectively of the lift and the horizontal component of the acceleration of an aircraft are combined to give a signal which represents the total available lift. Several different means for measuring lift and acceleration are described, and the signals may be combined electrically or mechanically, to operate an indicator such that when the craft is being flown to give maximum safe lift the pointer is central, or the combined signals may control lift or throttle via an automatic pilot. Measuring lift or angle of attack.-As shown (Fig. 1) a vane 14 projects through a wing near its leading edge and its deflections against centring springs, representing lift ratio, are signalled by means of an E-type transformer. The output signal is balanced against a potentiometer 58, to give a D.C. voltage whose value is zero for the maximum safe lift in the absence of horizontal acceleration. In a modification (Fig. 7, not shown), a vane projects laterally from the craft and controls the slider of a potentiometer. This device measures angle of attack rather than lift ratio. Measuring horizontal acceleration.-As shown (Fig. 1) one slider of a potentiometer 84 is controlled by a pendulum 96, and another by a gyroscope 100 to represent the angle of pitch, the gyro erecting motors being disabled during take-off. The voltage between the sliders thus represents the horizontal component of acceleration. In a similar device (Fig. 5, not shown), separate potentiometers are controlled by the pendulum and the gyroscope. In other arrangements (Figs. 3, 4, not shown), pendulum and sliding-mass type accelerometers controlling potentiometers are gyro-stabilized to give signals proportional to horizontal acceleration without correction by an additional signal. In a further arrangement (Fig. 6, not shown), a velocity signal is obtained by a known radar method and differentiated. Combining lift and acceleration signals.-As shown (Fig. 1), D.C. signals representing the horizontal component of acceleration, limited by diodes 148, 150, feed a calibrating potentiometer 146, the output of which is applied to one diagonal of a balanced bridge 70. D.C. signals representing the lift are applied to the other diagonal, and the combined signal is shown on a meter 80, the winding of which forms an arm of the bridge. After take-off the acceleration signal is fed through a capacitor 158 to by-pass long-term changes, due e.g. to gyro drift errors. In a modification (Fig. 2, not shown), the lift and horizontal accelerations are measured by self-balancing potentiometers, the movements of which jointly control the indicator, via differential gear. The combined signal may also control an automatic pilot.

Title: Improvements in or relating to radar reflectors
Inventor: PERRIN RAYMOND JOHN
IPC: H01Q15/20
Filed: 1956-11-20
Abstract: 807,362. Radio reflectors. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Aug. 6, 1957 [Nov. 20, 1956], No. 35405/56. Class 40 (7). A collapsible group of corner reflectors il formed by three approximately square metas plates. The first of these A, Fig. 1, has a slot A9, closed at each end, extending across almost the whole of one diagonal and spring metal tongues A1, A2, A3 and A4 cut out in the positions shown. The tongues A1 and A2 normally project to one side of the sheet and tongues A3 and A4 to the other. At the ends of the opposite diagonal to that slotted the corners are cut away to form surfaces A5 and A6. A further plate C, Fig. 4, without diagonal slots has all its corners cut away to form surfaces C5, C6, C7 and C8 facing in the directions indicated and is also provided with the cut-out tongues C1, C2, C3 and C4 shown, the first two projecting to the opposite side of the plate to the latter two. In assembling the reflector group the plate C is entered through the slot A9 until the surfaces C7 and C8 butt against the part of the plate A at the ends of the slot. To do this the tongues C1 and C2 have to be pressed in and spring out again, the tongues C2 and C3 helping to retain the plate C perpendicular to and symmetrical with respect to A. The third plate B (Fig. 3, not shown) is then taken. This has slots similar to A9 in both diagonals, no cut-away corners, and no spring tongues. It is passed down over the assembled plates A and B and past the tongues A1, A4, C1, C4 which spring out behind it to secure it in position against the surfaces A5, A6, C5 and C6. The resultant assembly is shown in Fig. 6. The plates can be readily separated for storing by pressing down the tongues and removing plate B and then plate C. Holes such as A8, B3 and C10 are provided to facilitate hanging the group in a boat's rigging. Alternatively an angle strip or bracket for lashing to a spar may be provided.

Filed: 1965-08-18
Abstract: 1,113,417. Circuits employing bi-stable magnetic elements. RADIO CORPORATION OF AMERICA. 18 Aug., 1965 [4 Sept., 1964], No. 35514/65. Heading H3B. In a magnetic memory of the type in which a stress wave or wave burst is propagated along an elongated member providing or having thereon a group of magnetic elements, the elements are spaced so that each wave or wave burst spans a plurality of elements. As shown, each magneto-strictive rod R includes three groups of three elements B, a conductor C being provided for each element in a group and being common to corresponding elements on different rods and to corresponding elements in different groups on the same rod. To write information a stress wave is generated by transducer 10 and write generators w 1 , w 2  and w 3  are sequentially activated to respond to input bits I 1 , I 2  and I 3 . The stress wave may span up to three adjacent elements but at any instant only one of the conductors C is energized. For non-destructive reading a similar stress wave is generated and passage of the leading edge through an element generates an output in a conductor C. Sense amplifiers S may be sequentially strobed. Separate conductors may be provided for reading and writing. In a modification thin film elements are provided on a glass substrate through which the stress wave is propagated. The easy axis of each film element is at angle to the direction of propagation of the stress and to the driving conductor. Operation may be as described, or alternatively the stress generator may be arranged to produce a burst of stress waves, the frequency of the waves in each burst being such that the separation of individual waves equals the separation of the thin film elements in each group. The groups may be separated by a greater distance. At a given time all the elements in a group are simultaneously stressed by the positive peaks of the stress wave, whereas any portions of the wave burst which extend to elements in adjacent groups stress these elements negatively and are ineffective. Different groups of elements may each store a word the bits of which are accessed in parallel.
