Title: Improved trip-free electric circuit breaker
IPC: H01H71/34
Filed: 1947-08-08
Abstract: 684,311. Automatic circuit-breakers. HEINEMANN ELECTRIC CO. Aug. 8, 1947 [April 6, 1939], No. 21963/47. Class 38 (v) In a trip-free circuit-breaker having a rigid moving contact bar, a wiping action at the contacts is obtained by providing the bar with an inclined slot for its pivot pin. The circuit-breaker comprises an L-shaped frame 1 having integral ears 3, 4, the ears 3 having slots 6 to receive the pivot pin 7 which passes through an inclined slot 9 in the switch bar or arm 8, whilst the ears 4 have bearing apertures 26 to receive the pivot pin 25 of the switch handle 24 and apertures 33 for the pivot pin of an armature. The switch arm is biased towards the open position by a spring 12 and is moved by the handle 24 through the medium of toggle links 13, 30, the links being normally latched in their extended position by means of a projection 27 abutting the arm 28<SP>1</SP> of a U-shaped member 28, Fig. 9. This arm 28<SP>1</SP> has a flat surface 28<SP>11</SP> which permits the passage of the projection 27 when the member 28 is turned about its arm 28<SP>1</SP> to trip the switch. The frame 1 supports an insulating tube 40 on which the trip coil 43 is wound. At the end of the tube is a fixed pole piece 46 and within the tube is a closely fitting spring loaded core 44. The armature 31 is spring biased and has a limb which co-operates with the pole piece 46 and the pole 2 formed by the end of the frame 1, and a limb 34 which may engage the limb 28a of the member 28. The circuit breaker is closed manually and may be opened manually by means of the handle 24 which moves the switch arm about the pivot 7 by means of the latched toggle links 13, 20, the slots 6, 9 which are inclined at different angles, causing the contact surface 62 of the arm 8 to slide on the fixed contact 61 when the switch is closed. When the switch is opened a similar sliding movement is obtained, and if the contacts have welded, the impact of the pin 7 against the ends of the slots 6 creates the shock necessary to break the weld. Under heavy overloads the magnetic field set up by the coil 43 attracts the armature 31 to trip the circuit breaker by breaking the toggle as the limb 34 turns the member 28. During more moderate overloads the flux of the coil 43 is not sufficient to trip the circuit breaker until the core 44 has been drawn into the coil to improve the permeability of the magnetic circuit. As the core 44 closely fits the tube 40 the air or oil in the tube will retard the movement of the core and impose a time delay which will vary inversely with the strength of the current. The fixed contact 61 consists of a conducting strip 58 wound around an insulated core 60 between magnetic blow-out plates 63. A stop 37 limits the outward movement of the armature. Specification 684,327 is referred to. The Specification as open to inspection under Sect. 91, also included the subject-matter of Specification 684,390. This subject-matter does not appear in the Specification as accepted.

Title: Echo signal apparatus for producing a representation of the echo signals on the screen of a colour cathode ray tube
IPC: G01S13/58
Filed: 1971-04-19
Abstract: 1291395 Sonar FRIED KRUPP GmbH 19 April 1971 [17 Feb 1970] 21995/71 Heading H4D  An echo signal apparatus has a receiver with a number of outputs each of which has a connected rectifier and frequency selective network supplying a colour matrix which passes signals to colour C.R.T. to display echoes with a colour which indicates their Doppler frequency. Receiver 1 has n outputs each of which is connected to a high-pass 2 1 -2 n  and low-pass 3 1 -3 n  filter. The detected filter outputs are sequentially stored in memories 9a, 9b via switches 6, 7 and read out to a colour matrix 10 which feeds the three guns of a tri-colour C.R.T. 12. The matrix 10 provides a characteristic colour for the display according to the Doppler frequency of the echo signal. The colours range continuously from red for maximum approach velocity to white for stationary targets and green for maximum receding velocity. In a modification (Fig. 1, not shown) the receiver outputs are fed to frequency discriminators providing positive, negative or zero voltage outputs according to the echo Doppler frequency. This output together with the detected receiver output is passed to sum and difference circuits whose outputs are fed to the colour matrix. Generators may be provided to produce coloured markers on the display.

Title: Improvements in or relating to electrical remote two-condition indicating systems
Inventor: RAYNER THOMAS ROBERT
IPC: G08C15/02
Filed: 1947-08-12
Abstract: 651,401. Indicating and locating leakage. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Aug. 12, 1947, No. 22327. [Class 99(ii)] [Also in Group XXXVIII] A system for signalling over a line to a central point, a two-condition indication of the state of a number of pieces of apparatus comprises a number of galvanometerrelay-transmitters in which the mechanically-oscillating armatures generate pulses of characteristic frequency to actuate similar relays at the central point. A condition responsive device releases the latch 15 which normally holds the permanent magnet armature 13, of the relay such as TGC, off-center, and removes a short circuit from the coil terminals T5, T6. The resulting pulse is amplified and fed to similar galvanometer relays causing the armature 16 of relay RGC, which is the same characteristic frequency, to oscillate and energize relay AC which sticks up over AC1 and makes audible and visible alarm circuits over AC2-3. The transmitter relays are reset by throwing switch KT1-2 whereby d.c. flows over the line to deflect any unlatched armature. The alarm circuit is reset by opening key KR. The oscillating armature may alternatively be the coil of the relay. The invention is described as applied to a gas pressure supervisory sytem associated with a gas-filled electric cable. Specifications 622,585, [Group XXXVII], and 630,574, [Group XXXII], are referred to.

Title: Process and apparatus for separating intermixed divided materials of different specific gravities
IPC: B03B4/02
Filed: 1926-09-13
Abstract: 287,184. Peale, R., Davies, W. S., and Wallace, W. S. Sept. 13, 1926. Pneumatic separating.-Relates to a process and apparatus for separating materials of different densities of the kind in which the materials are stratified on an air pervious table by the combined action of the reciprocating motion of the table and of air forced up through them, as described in Specification 222,186, and consists in arranging the separating riffles on the table so that the heavy materials are directed outwardly to both sides or inwardly to a'discharge edge formed by making the forward side of the table of bifurcated shape. The upper stratum of lighter material moves longitudinally so as to discharge over the end or sides and may be directed by guides placed above the riffles. Means are provided for controlling the distribution of the air pressure supplied to the table. One construction is shown in Fig. 1, in which the air pervious table 23 is provided with riffles 28 inclined forwardly and outwardly to the sides 26, 27 and is formed with two diverging discharge edges 31 leading to a shoot 32. In a modification, deflecting strips may be disposed, at variable heights, above the riffles 28 to direct the lighter material to the discharge edges 31. In a further modification the riffles may be parallel to the table sides or slightly inwardlv inclined so as to direct the heavy materials to the discharge edges 31, the lighter materials being directed to the sides. Another construction comprises a table having diverging riffles and converging sides so that the discharge of the lighter materials takes place over the end and also partly over the side edges of the table. Preferably, the riffles terminate short of the sides of the table, leaving a longitudinal channel 30 leading to a series of discharge openings 42, Fig. 2, with adjustable plates 47. The openings lead to shoots 49, fitted with adjustable hinged plates 62 by which the discharge of the heavy material can be regulated. The various grades of material are deposited on conveyers. Baffles 72, 73 adjustably positioned direct the middlings to a separate discharge. The air chamber may be divided into compartments by adjustably fixed partitions, and may also be provided with adjustable baffle plates so as to control the intensity of the air pressure for the discharge of the lighter or heavier materials or both. In one construction shown in Fig. 6, the space under the table is divided by partitions 227, 228, and the air pressure controlled by independently or simultaneously adjustable baffle plates 217. The air control devices may be used in conjunction with a table in which the air-perviousness is varied at different parts.
