Title: Telephone intercommunication systems
IPC: H04M9/00
Filed: 1970-10-06
Abstract: 1356927 Interconnection systems POST OFFICE 16 Sept 1971 [6 Oct 1970] 47508/70 Heading H4K An interconnection system includes a plurality of telephone instruments having access to a common exchange line but capable of interconnection without passing through the exchange wherein each instrument has a calling circuit including first and second calling indicators for use when the particular instrument being called is disengaged (on hook) and engaged (off hook) respectively. In the part of the four station system shown the call lines 1, 2, 3, 4 interconnect the stations and each station can selectively energize a call line by operation of keys KR1-KR4. The instrument "hook switch" comprises contacts GS1, GS2 which are shown in the operated state for station 1 and cause the intercom lamps L to light. Latching key KE is used to obtain an exchange call and operation of this key will extinguish the intercom lamps. If station 2 is called by depressing key KR2, as shown, a circuit is completed through the call 2 line and the unoperated GS2 contacts to sound buzzer Z in station 2. The current in this circuit flows through R1 in station 1 and drives the emitter of transistor T more negative to extinguish lamp L in station 1. If station 2 was engaged in an exchange call then GS2 would be disconnected from the buzzer circuit and the calling current would be applied to the base of transistor T in station 2 and will cause the associated lamp to be extinguished. The lamp in station 1 will not extinguish but may be dimmed to give an indication that station 2 is engaged. The system described has an additional station connected in parallel with the fourth station. In this case either station can answer or make an intercom call and one station can be used on the intercom whilst the other is making an exchange call.

Title: Improvements relating to winding frames
IPC: D01H1/36
Filed: 1965-11-09
Abstract: 1,121,041. Builder motions. WHITIN MACHINE WORKS Inc. 9 Nov., 1965 [9 Nov., 1964 (3)], No. 47550/65. Heading D1D. In a machine for winding filamentary material on a bobbin 30 by a guide, such as a flyer 16, which rotates about the bobbin a pneumatic piston-cylinder device 42 effects the necessary adjustment of the wind-up rate, the traverse velocity and the traverse length during the build up of the package. As shown, dogs 80, 82 threaded on opposed pitch portions of a spindle 90 are reciprocated with the bobbin rail 98 to actuate a switch arm 84. At each actuation of arm 84 one clutch of a pair 106, 107 is de-energised and the other energised (see circuit of Fig. 3 not shown) to reverse the drive passing to the traverse rack 100 from the bottom cone 18 of the usual winding on variable speed arrangement. Each operation of arm 84 also actuates via the circuit of Fig. 3 a solenoid operated pneumatic valve 48 to operate the piston of device 42; this actuates a ratchet (see also Fig. 2 not shown) which, through a gear train 36 moves the rack 34 to shift belt 20 and alter the speed of the bobbin and traverse in the desired way. Drive is taken by a gear train 130 from rack 34 to rotate spindle 90' so as to change the separation of dogs 80, 82 and thus produce the desired progressive decrease in the traverse length. A motor 140 and normally open clutch 144 winds rack 34 and the associated elements back to their starting position at the end of a wind. A brake 116 normally held inoperative by electrical means brakes shaft 104 to hold the bobbin rail in position should the electricity supply fail.

Title: Target-tracking processes
IPC: G01S13/72
Filed: 1974-11-05
Abstract: 1447815 Radar tracking system SIEMENS AG 5 Nov 1974 [7 Nov 1973] 47726/74 Heading H4D A process for tracking the course of a number of objects flying in close formation makes use of a radar system, a signal processing device, and a digital computer, said device being arranged to provide the computer with positional information about said objects as successively received from the radar system. During a first echo-pattern analysis echoes E1-E6 received from said objects are each enclosed in an individual expectation zone AR1-AR6. During a second echo-pattern analysis further echoes are received from said objects, and it is determined which of said further echoes, e.g. E7, E8 lie in common or overlapping sections of said expectation zones, whereupon objects corresponding to said common sections are considered to be flying in formation. The centres of the first and second echo patterns are determined, and the interval between them is used to determine the speed of the formation, thereby enabling prediction points to be determined for respective echoes, around which points further expectation zones can be arranged. The radar system receiver passes echo signals to the signal processing device where said signals are quantized and digitized for the computer. All relevant information concerning a flight formation, such as the number of objects comprised, their relative positions, and the average speed, is calculated and presented on a display. The information may be recorded, for example on magnetic tape. Initially, the expectation zones have the forms of squares or circles with sides or diameters of 2V max .T, where V max  is amaximum speed value, and T is the time lapse between successive analyses. When information is available concerning the radial speed V rad  the expectation zones set up around the echoes have elliptical forms with radial and azimuthal semi-axial dimensions respectively dependent upon V rad  and the maximum possible speed component in the azimuthal direction, with due allowances for measuring errors and for the maximum possible acceleration of the flying objects. If height information about the flying objects is available, the expectation zones can be made three-dimensional.

Abstract: 1.094,128. Earth working &c. TALLINSKY EXKAVATORNY ZAVOD. Nov. 25, 1964, No. 37892/64. Heading E1F. In a trench excavator having a bucket carrying frame 2 pivoted at 27 to the excavator body and also supported by a member 6 in contact with the bottom of the trench, fluid is supplied to and released from hydraulic piston/ cylinder units 3, 5 so that the trench bottom is maintained straight in spite of variations of the height of the ground on which the body stands. The unit 3 is pivoted to the body and the frame, and the unit 5 is pivoted to the frame and a link 8. The link 8 is pivoted to the frame and to a member 9 pivoted to the member 6 and having a slot engaged by the end of the frame. Variations in the height of an element fixed to the excavator above a wire parallel with the trench bottom cause signals to actuate an electro magnetically operated slide valve (21) controlling flow to and from the units. The buckets are lowered relative to the body by supplying fluid to contract the unit 3 and by releasing fluid to permit the unit 5 to contract. The buckets are raised by supplying fluid to extend the unit 5 and by releasing fluid to permit the unit 3 to extend. For small variations of the height of the ground the valve is set so that the length of the unit 3 only is permitted to vary. The member 6 carries a pipe layer 10.

Title: Spring coiling machine
IPC: B21F3/00
Filed: 1965-11-11
Abstract: 1,066,659. Coiling. LEWIS SPRING & MANUFACTURING CO. Nov. 11, 1965 [Feb. 2, 1965], No. 47933/65. Heading B3E. [Also in Division F2] A spring coiling machine in which wire is coiled by being fed against a coiling point member is characterised in that the coiling point member is movable in three mutually perpendicular directions and is formed with two grooves at right-angles to one another so that hooks or bends may be formed at the ends of the spring. Wire is fed by rolls 14, 15 through guides 12, 13 against a coiling member 20 to be received in a groove (55), Fig. 6 (not shown), thereon and formed thereby into a helical coil 21. A groove (56), in the member 20, serves to cause the wire to bend into hook form when the member 20 is suitably positioned. The member 20 is movable about a pivot 61 in a holder 30 by cam means carried by a slide 70 moved by a cam 80 on a shaft 40. The holder 30, in turn, is movable about a pivot 31 in a slide 25 by a cam 41. The slide 25 is movable to and from the feed rolls. The member 20 is moved about the pivot 61 to position it to effect either close or open coiling. Various formations can be provided at the ends of the coil by suitably moving the member 20. A knife 50 on a rockable shaft 52 cuts off the coil from the continuous length of wire.

Title: Generation and reproduction of characters
IPC: G09G1/18
Filed: 1966-10-27
Abstract: 1,147,060. Cathode - ray tube displays. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Oct., 1966 [30 Oct., 1965], No. 48190/66. Heading H4T. An arrangement for generating and displaying characters utilizes a magnetically deflected cathode-ray display tube 1 supplied with beam bright-up pulses from a magnetic core character generator matrix 6 in which the character is " written " by selector means 9 and a complete scan of the horizontal rows of which is produced by vertical selector means 11 for each selection of a vertical column by horizontal selector 10. The characters, which are stored in digit form in a plurality of registers in a memory 13, are transferred to a buffer stage 12 by the output of stage 1 of selector 10 and are then " written " in to matrix 6 by the output of stage 2. During the operation of each of stages 3 to 7 a complete scan is effected by selector 11 and the resulting output pulses, depending on the character " written " are supplied to the beam intensity control electrode via amplifier 8. Each operation of stage 8 of selector 11 initiates the fly-back of a vertical line scan generator 3 so that the character is reproduced as a pattern of bright dots in a 7 x 5 matrix. At the end of each cycle of selector 10 the output of stage 8 is supplied to an AND gate 16, and this together with the "1" output of a bi-stable trigger 17 causes a digit selector 15 to step-on one count, this operation continuing until all the characters in the selected register have been displayed. Each character is spaced from the next by an amount determined by the time of operation of stages 1 and 2 of selector 10 and the contents of a register are displayed in a horizontal trace during a single sweep of the horizontal deflection generator 4. When all the characters (digits) in one register have been displayed selector 15 which will have reached a full count, then supplies a pulse which causes selector 14 to select a new register and switches trigger 17 to the "0" state. This initiates the fly-back of generator 4 and during this period the tube beam is blanked by the "0" output supplied to a modulation circuit 5. The blanked condition is maintained for the duration of three cycles of selector 10 by supplying the output of stage 8 via an AND gate 18, also receiving the "0" output of trigger 17, to a threepulse counter 19, the output of which then switches 17 to the "1" state and a new cycle commences. The next horizontal line of characters is then traced at a different vertical level by utilizing an output from selector 14 to control the application of shift signal from means 20 to the vertical deflection coils in scanning yoke 2.
