Abstract: 374,063. Photographic type composing. UHER, E., 49, Retek Utca, Budapest, and UHERTYPE AKT.-GES., Kubli House, Poststrasse, Glarus, Switzerland. Feb. 23, 1931, No. 5697. Convention date, Feb. 22, 1930. Drawings to Specification. [Class 98 (i).] In a method of photographic type composing, the actuation of the keys for the selected characters sets up intermediate control means which effect the exposure of the characters only after a predetermined interval, justification being automatically effected in this interval. In carrying out the method the control means comprise balls fed by the character keys on to a drum which is advanced in steps as described in Specification 334,499, [Class 98 (i), Photographic cameras &c.]. The keys also produce a forward stroke of a slide, according to the width of the character, which is transmitted to a travelling bar for effecting justification as described in Specifications 350,597 and 351,043, the movement being transmitted to a film band on which the exposures are made. The characters are provided on a transparent drum and are projected by a revolving inclined reflector as described in Specifications 331,305, [Class 98 (i), Photographic cameras &c.]., and 373,636. Specification 374,064 also is referred to.

Title: Improvements in and relating to contact structures for electric circuit interrupters
IPC: H01H1/18
Filed: 1942-04-30
Abstract: 556,185. Switch contacts. BRITISH THOMSON-HOUSTON CO., Ltd. April 30, 1942. No. 5843. Convention date, May 1, 1941. [Class 38 (v)] When the movable contact member 15 (shown as the bridging member of a conventional oilswitch) is raised, the arcing surface 16 thereof engages and rotates the member 18 about pivot 17, so moving the part 18b clear of back stop 23 and towards the cooperating surface 15. In the position when both surfaces 18a, 18b engage member 15, the slot 19 is inclined, so that further upward movement of 15 causes the member 18 to wipe along it. In the fully-closed position, spring 21 is deflected somewhat from the vertical, and acts on 18b with more force than on 18a, the force being supplemented by the electrodynamic action of the current loops. There may be a row of members 18 on pivot 17, in which case the springs 21 are arranged, as in Specification 532,034, to have different natural periods of vibration.

Title: Power failure indicator
IPC: G01R19/145
Filed: 1950-03-08
Abstract: 671,496. Voltmeters. BENDIX AVIATION CORPORATION. March 8, 1950 [March 11, 1949], No. 5882/50. Class 37. [Also in Group XXXV and XXXVIII] A two-position indicator comprising a 3-phase hysterisis motor whose rotor is constricted to move a maximum of 90 degrees against a spring thereby bringing coloured indicator vanes into view, has a spring strength such that when the applied voltage is low the rotor moves less than 90 degrees, and the voltage deficiency may be determined. The motor consists of a 3-phase stator winding 27 and laminations 26, held in position inside a casing 11 by a spring washer 30; the rotor comprises a shaft 38 carrying an armature 40, which may be unmagnetized ferrous metal or a permanent magnet. The opposing torque is produced by a coil-spring 44, fixed between the shaft 38 and a pin 45, two further pins 47 being attached to the shaft 90 degrees apart to abut the pin 45. Attached to the end of the rotor shaft 38 is an indicator disc 51 divided into contrasting coloured quadrants, opposite quadrants being visible through cut-outs in a screen 55, through a glass cover 56. The particular colour of the vanes seen through the glass will therefore indicate whether the supply voltage to the field windings is on, or off, or weak.

Abstract: 1,199,394. Shell moulds and cores, moulding machines. R. H. BARROW. 7 Feb., 1968 [27 Feb. 19671, No. 6153/68. Heading B3F. Moulds and cores having a thin shell facing are prepared by covering the surfaces of a heated pattern with a dry resin coated granular medium, heating the medium to harden it into a thin non-self-supporting shell having an average thickness of less than 1/8 inch and removing any unhardened medium, curing the shell while still in contact with the pattern and applying a second moist binder-coated medium having a coarser grain size than the first medium to form a rigid backing for the thin shell, the second medium being set by heat from the pattern. Moulding machines.-In Fig. 1, a two-part core-box 17 is rotatable about 180 degrees around a horizontal axis. Dry-moulding mixture is supplied from a hopper 38 to a magazine 27 which is moved under a blower-head 33 to deliver the mixture to the core-box. After setting the core-box is rotated about 180 degrees to deposit excess moulding mixture into a hopper 25, and then rotated to its original position. A second magazine 28, containing moist moulding mixture, from a hopper 39, is brought above the core-box and the charge blown into the core-box. After setting, the core-box halves 17a, 17b are opened by a fluid motor 21 to allow the completed core to be removed. In Fig. 2, the first medium is delivered by compressed air from below the corebox and the second medium by gravity and compressed air above the core-box.  The machine, on wheels 55, is reciprocated between the first and second mixture blowers by a fluid motor 56.

Title: System for acoustic signal detection
IPC: G01S3/803
Filed: 1966-02-11
Abstract: 1,111,772. Acoustic direction finding. GENERAL DYNAMICS CORPORATION. 11 Feb., 1966 [15 Feb., 1965; 28 June, 1965], No. 6220/66. Heading H4D. The Specification describes an acoustic direction finder analogous to a crossed loop radio direction finder, one embodiment (the second) comprising a radio goniometer. In the first embodiment omnidirectional audio receiver transducers 1, 2, 3, 4 of equal sensitivity are arranged at the corners of a square, the whole assembly being swung by magnet 53 so that the pair of transducers 1, 3, face north. If # is the angle of incidence of the incoming sound wave with respect to north, Fig. 2, and d is the distance between the opposed transducers, then the outputs of the four transducers are:- The signals a 1 , a 3  are fed to a difference amplifier 34 to give signal b 2 , and signals a 2 , a 4  are fed to difference amplifier 30 to give signal b 1 . Thus Signal b 2  is passed through a 90-degree phase shifter to give signal b 3  where:- Signals a 1 , a 2 , a 3  and a 4  are also added at 23 to give a reference signal b ref  appearing to originate from a pseudo transducer 25 at the centre of the array. Signals b 2  and b 3  correspond to a " figure of eight " response pattern, whilst b ref  corresponds to an approximate omnidirectional response pattern. Signals b 3  and b 1  are added together at 35 to give a signal b 4  having a phase (wt + # b ) where Angle # b , a function of the desired angle 0 is determined by feeding signals b 4  and b ref  to a phase detector and the output at 42 is fed to a utilization circuit 41 to display the angle #. In the second embodiment, Fig. 4, the signals b 1  and b 2  are fed to respective mutually perpendicular primaries of a goniometer resolver 63 having a secondary rotated under the control of a beam direction control means 64. The output of the rotating secondary at 66 has an envelope varying in a " figure of eight " manner, and this is altered to a cardioid C 1 , Fig. 5, by adding the signal b ref  thereto at 67. By phase reversing the resolver output at 69 and adding thereto the reference signal, a signal having a cardioid variation C 2  positioned 180 degrees from cardioid C 1 , is produced. The two cardioid signals are fed to a threshold gate 74 which only passes the signal C 1  when the signal C 2  is below a just above noise level threshold T 1 , Fig. 6. The output at 77 thus simulates a narrow direction finding beam. By feeding the arrangement at 77, a narrow directional acoustic beam is transmitted.

Abstract: 688,696. Inductor alternators. BRITISH THOMSON-HOUSTON CO., Ltd., and RABY, K. F. Feb. 23, 1951 [March 15, 1950], No. 6507/50. Class 35. In a single-phase heteropolar inductor generator the relative arrangement of the stator and rotor slots and teeth are such as to produce alternate zones of relatively high and low reluctance in the air gap, the zones interchanging when the rotor R moves through one-half rotor slot pitch, and the pitch of the stator small teeth is different from that of the rotor teeth. In the known machine shown in Fig. 1, each coil of the exciting winding has its opposite sides located in alternate stator slots SE embracing the high and low reluctance zones, the A.C. winding being located in slots SG (only one is shown). Fig. 3 shows the stator having four large teeth each having a number of small teeth, the pitch of which is different from that of the rotor teeth. The pitch of the stator large teeth is an odd multiple of # radians electrical so as to obtain the required alternate zones of high and low reluctance. The object of the above arrangement is to reduce the E.M.F. harmonics of inductor generators. Specification 554,827 is referred to.

Abstract: 382,187. Cigar making machines. TRIGGS. W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Sept. 24, 1931, No. 6767/32. Divided on 380,944. [Class 130.] Fixed and movable moulds 12, 12a, in which are cavities for the reception of a cigar bunch, are carried by a rotatable turret 10, and in each lower fixed mould 12 are slots within which lie fingers 24 to lift the cigar bunch out of the lower mould 12, after the upper mould 12a is raised. Each mould 12a is carried by one arm 14 of a spring-actuated lever, mounted on a rock shaft 15 on a bracket carried by the lower mould, the other arm 17 carrying a roller 18 which coacts with a stationary cam 19. The cam ensures that the moulds are closed until the rollers 18 engage a part 19a of the cam and a guide cam 21 when the moulds 12a are lifted. After one of the moulds 12a is lifted, the fingers 24 with the cigar bunch are raised from the slots in the corresponding mould 12 by a fixed stop 28, which coacts with a spring-pressed arm 26 fixed to the fingers 24. The cigar bunch is then removed, the fingers 24 are lowered, new bunches are inserted into the moulds 12 and the moulds 12a are then lowered. The turret 10 is intermittently rotated by a pawl 32, mounted on a lever 34, which coacts with a ratchet 29 secured to the turret. The lever 34 is oscillated from a cam by links 35, 36, 37a, 38, 39, and has arms 48, 48a which through a roller 47 oscillate a shaft 44 to which knives 43 are adjustably secured. The forward movement of the shaft 44 trims the cigar bunch, and the reverse movement returns the knives to their inoperative positions.
