Abstract: 125,856. Arter, J. J. B., and James Cycle Co. Aug. 6, 1918. Methods of sighting.-Consists in an indicator employed when ranging guns from one or more flank positions, and comprises (1) an electric alarm-bell at each flank position operable from the gun position, and (2) electric indicators at the gun position each operable from a flank position, whereby each flank observer is able to report bursts to right or left of the target as seen from his position. Fig. 2 shows the arrangement between the gun position and one flank position; the arrangement is the same for every other position. An alarm bell b<1> at the flank station a<1> is adapted to be rung when a push c<1> at the gun position A is depressed. An indicator at the gun position, comprising an armature d<1> carrying a pointer and controlled by electro-magnets e<1>, f<1>, if wired to a. 3-pole switch g<1> at the flank station in such a fashion that when the switch g<1> is turned to left or right, the pointer d<1> moves in the same direction. The indicators may alternatively comprise two electric bells, or two indicator disks. A bell h at the gun position is wired to all the flank stations, to enable the flank observers to indicate, according to some prearranged code of rings, to which of a number of targets the signalled observation refers.

Patent GB-861895-A (GB)
Title: Improvements in and relating to taximeters
IPC: G04F8/08
Filed: 1959-04-15
Abstract: 861,895. Control of motors; switching held set and freed mechanically. KIENZLE APPARATE G.m.b.H. April 15, 1959, No. 12789/59. Classes 38 (3) and 38 (5). [Also in Group XIX] In a taximeter the control-shaft is driven to the " for hire," " hired," and " stopped " positions by an electric motor under control of a manually-operated switch, the motor being dynamically-braked to rest in each position by short-circuiting the armature while the stator circuit is maintained temporarily by a delayed release relay. In one embodiment, Figs. 1, 2, where the control-shaft 34 may be stepped in one direction only, depression of a push-button 1 moves a slide 3 to the position shown in which the slide is locked by a pawl 11 pivoted thereto and cooperating with a stop 16. Contacts 23-24 are thereby closed by the slide and contact pairs 19-21, 20-22, are closed by the pawl acting through a leaf-spring 18 whereby a delayed release relay E, Fig. 2, is energized to close contacts El, E2 to energize the motor armature 33 and stator 31. As the motor-driven control shaft 34 approaches its next stop position, a lobe of a cam 36 on the control-shaft lifts the pawl 11 clear of the stop 16 so that the slide is moved to the right by its biasing-spring 10. Shortly afterwards, a further cam 35 on the controlshaft permits the leaf-spring 18 to rise and open contacts 19-21, 20-22 whereby the armature is short-circuited, but the stator coil remains energized for the release time of the relay E, thus braking the motor to rest. In another embodiment, Fig. 3 (not shown), and Fig. 4, push-buttons 50, 51 are provided for reverse and forward stepping of the controlshaft, respectively. Operation of either pushbutton energizes an associated relay A (reverse), B (forward). The operated relay A or B precludes operation of the other relay (B or A), locks itself, and energizes a common delayed release relay D. In the case of forward rotation relay D energizes the motor armature 33 and stator 31 in series directly over contacts D3. For reverse rotation the motor circuit is again completed by relay D at contacts D3 but contacts A3, A4 reverse the armature current to reverse the direction of motor rotation. Camoperated contacts 80, 81, open as the desired stop position is approached, to de-energize the operative relays whereupon the armature is short-circuited by contact B4 while the stator 31 remains energized for the release time of relay D, to effect braking of the motor to rest. Two cams operated by the control-shaft, Figs. 5-8 (not shown) are used, one for forward and one for reverse rotation control. The cam profiles are slightly offset circumferentially relative to one another, the arrangement being that the leading cam is non-operative.

Title: Improvements relating to the frames of motor-assisted cycles
IPC: B62K19/02
Filed: 1961-04-10
Abstract: 903,578. Cycle frames. ATELIERS .DE LA MOTOBECANE. April 10, 1961 [June. 28, 1960], No. 12840/61. Classes 79(3), 136(1) and 136(3). A frame for a motorassisted cycle is of heterogeneous construction and comprises a front part of stamped metal plates forming a girder 3 and a rear part of formed tubes and sections 1-10-11; a fuel tank 16 and a luggage carrier 17 contributing to the rigidity of the rear assembly and forming a quadrilateral with the saddle tube 1 and rear fork . arms 11.

Title: Improvements in excitation systems for alternators
IPC: H02P9/38
Filed: 1953-05-08
Abstract: 738,524. Exciting alternators; automatic voltage control systems. LAURENCE, SCOTT & ELECTROMOTORS, Ltd., SCHWARZ, B., and SCHWARZ, K. K. April 22, 1954 [May 8, 1953], No. 12923/53. Classes 35 and 38 (4). A single or polyphase A.C. generator has one field winding connected for shunt or separate excitation by a substantially constant voltage source and another field winding for current compounding. In the single-phase form shown the shunt field winding 1B of alternator IA is fed through rectifier 2 and adjusting rheostat 3 with a smoothing condenser 4 while the current compounding field winding 1C is fed from adjustable-tap current transformer CS and rectifier 6 with smoothing condenser 7. For starting, a relay 8 connects the rectifier 6 directly across the alternator terminals at contacts 8B, or alternatively the winding 1C may be connected in parallel with field 1B. The current transformer is short-circuited during starting by contacts 8D while resistance 9 connected by contacts 8C prevents " flutter " of the relay when shutting down. If desired, the shunt winding may be fed from a tapping on the generator winding, the whole winding being used for build-up. The current transformer may be omitted and the series field fed by the whole load current with an adjustable shunting rheostat. Second order variations due to temperature, power-factor, speed variation, &c. may be corrected by an additional conventional automatic voltage control device, e.g. of saturable reactor, or vibratory type, connected in the shunt field circuit or in an additional parallel connected shunt field circuit. In a further modification, the winding 1B may be excited from a mains-fed rectifier or selfexcited D.C. exciter controlled by an automatic regulator to cover second order variations as above. The compounding winding may be of three-phase layout so as to provide a damping circuit.
Patent GB-871433-A (GB)
Title: Improvements in or relating to chemical reactions and apparatus for use therein
IPC: C22B1/08
Filed: 1958-04-23
Abstract: <PICT:0871433/III/1> <PICT:0871433/III/2> High temperature reactions in gaseous suspension, particularly the chlorination of highly refractory ores are carried out in apparatus comprising a mixing nozzle 10 producing a fluidized mixture of solid and gas, a graphite reaction tube 14 heated by spaced electrodes 22 and 23 and surrounded by a steel shell 16 packed with carbon black, a graphite chamber 20, a graphite cyclone separator 39 and a condenser 44.  A nickel tube 13 leading from the mixing nozzle 10 makes an expansion joint with the reaction tube 14 by a graphite sleeve 15 and carries a flange 17 joined to the shell 16 by bolts 18 and an insulating gasket 19. Covers 31 carrying the graphite blocks forming the electrodes (see Group XI) are also sealed to manholes 30 in the shell by bolts 33 and gaskets 32.  The chamber 20 and cyclone 39 have a similar construction of casing to that surrounding the tube 14.  Powdered carbon and ores, such as oxides or silicates of titanium, zirconium, molybdenum, vanadium, columbium or tantalum are supplied through line 12 and chlorine through line 11, the fluidized mixture passing from the nozzle 10 into the tube 14. Chlorine passes through the porous tube into the surrounding carbon black, Alternatively, an inert gas or nitrogen can be introduced directly into the carbon black. Reaction products enter chamber 20 where the solid materials, e.g. untreated ore, carbon, &c. form a fluidized bed, and where high boiling point products condense, low boiling point fractions passing on through the cyclone 39 to the condenser 44.  In a modification, Fig. 4 (not shown), the reaction tube connects directly to a graphite cyclone with a condenser following downstream, and a further modification, Fig. 5 (not shown), retains the chamber 20, dispensing with the cyclone.  A final modification, Fig. 6 (not shown), has eight reaction tubes disposed radially around a graphite chamber wherein solids form a fluidized bed and which may be connected either to a cyclone and then to a condenser or directly to a condenser.  The apparatus may be used for the recovery of iron from ilmenite, the mixture of ore carbon and chlorine being heated in the tube 14 to a temperature above 1600 DEG C. forming titanium and iron chlorides. The iron chloride being unstable at this temperature, iron as vapour or very fine globules enters chamber 20 where it condenses and is removed in molten form, the titanium chloride being condensed at a further stage of the apparatus.  Other metals may be recovered where their chlorides dissociate at high temperatures in the presence of carbon without forming carbides.  Petroleum may also be produced by the hydrogenation of powdered coal introduced through line 12, the hydrogen entering through line 10 and impregnating the carbon black around the graphite tube.  Solid products are removed by the chamber 20 and the cyclone 39, the gases being condensed in a conventional condenser.  Specification 369,943 is referred to.

Abstract: 1302599 Deboning meat GEO A HORMEL & CO 18 March 1970 [28 Aug 1969] 13020/70 Heading A2U  Apparatus associated with means for deboning a chunk of meat comprises a conveyer adapted to engage and support an external fitting on a bone-engaging device both before and after extraction of the bone from the meat, and means for removing the bone-engaging device and extracted bone from the conveyer and separating the bone from the bone-extracting device. The apparatus described removes the bones R, H from a shoulder of pork S, and the bone-engaging device consists of a threaded pin 26 which is driven through the bone R and screwed into the joint between the bones R, H, and has an external fitting 22 of cylindrical form with upper and lower annular grooves 24, 25 and a diametrical slot 23. The pin is driven into the bones in a pinning machine 11, after which the meat is suspended from a recessed plate 35 engaging the lower groove 25 on the fitting 22 and moved by a hydraulic jack 38 towards the conveyer 40 which has upper and lower endless tracks 43, 44 carrying a plurality of support members 45 which are moved by a chain passing over a driving sprocket 65. A lower bracket 55 on one of the members 45 engages the upper groove 24 of the fitting 22, removes the fitting from the plate 35 and carries the meat to a position where an arm 74 engages the lower groove 25 of the fitting 22 and transfers the meat to a deboning unit 67 in which the meat is separated from the bones by high-velocity water jets. The fitting 22 and extracted bones are then transferred by an arm 75 to an upper bracket on a member 45 by which they are conveyed to apparatus 82 which detaches them from the conveyer and removes the pin from the bones. This apparatus comprises a slotted plate 87 which receives one of the grooves of the fitting 22, a pair of jaws 100 operated by a hydraulic jack 95 to grip the bones, a shaft 116 driven by an electric motor 107 through reduction gearing 106 and movable axially by jacks 117 to bring a diametrical projection (not shown) on the end of the shaft into engagement with the slot 23 in the fitting 22, and a hydraulic jack 91 to exert a downward force on the jaws 100 while the fitting 22 is being rotated. Extracted pins are carried up a vertical guide 135 and transferred to an inclined track 142 by which they are returned to a magazine of the pinning machine 11. The track may pass through a steam cleaning station.

Filed: 1952-05-22
Abstract: 741,364. Automatic exchange systems. LICENTIA PATENT - VERWALTUNGSGES. May 22, 1952 [May 22, 1951], No. 13045/52. Class 40 (4). In a circuit arrangement in which the outlets of a set of multipled switches are connected to the outlets of multipled selectors and the test multiples of the switches and selectors are connected together, the resistances in the testing circuits and of the test relays of the switches and selectors are such that when a switch seizes an outlet, the outlet is busied to the other switches and selectors and when a selector seizes an outlet the outlet is busied to other selectors but a free switch can connect itself thereto. The arrangement is particularly applicable to a system in which a switching centre is connected over a plurality of junctions to an exchange. Each junction has switches at each end stepped in unison and the exchange end switches are multipled and connected to the final selectors. The exchange-end of such a system is shown in the drawing and is described below. Incoming call. A final selector, say LW1, is set to the outlet corresponding to the called subscriber and its test relay P1 operates in series with a sluggish relay E1 associated with the allotted junction AL1. The former busies the outlet to other final selectors LW2, LW3 by 'shunting its high resistance winding; the latter busies the junction and starts the switch AW1 which hunts for the outlet marked by the final selector. Test relay C1 operates, shunts its high resistance winding to busy the outlet to other switches such as AW2 and energizes a relay to actuate a contact r1 to allot the next free junction by connecting the multiple to a relay similar to E1, which relay owing to the resistance Wi1 is unable to operate in parallel with the low resistance winding of C1 but would operate if another final selector had seized an outlet. The resistances Wi2 enable the test relays of more than one final selector to hold in series with relay E1. Rectifiers Gl de-couple the multiple connections. Outgoing call. Switch AW1 and the switch at the satellite step in unison until the calling line is found and the contact r1 is actuated to allot another junction to the final selectors. When the switch AW1 comes to rest, test relays C1, K1 operate in series, and the latter extends the talking circuit to a pre-selector VW1. However, if before K1 operates a final selector seizes the outlet corresponding to the caller, K1 is short-circuited over the low resistance winding of the test relay of the final selector and the incoming call is given preference.

Title: Improvements in turning bars for web material
IPC: B41F13/06
Filed: 1955-05-06
Abstract: 770,723. Feeding webs. LEVEY CO., Inc., F. H. May 6, 1955 [March 4, 1955], No. 13144/55. Class 100(1) A turning-bar assembly comprises a supporting frame 4, a plurality of parallel supporting links 8 each pivotally attached at one end to the frame 4 and at its other end to a fixed support, thereby permitting movement of the frame 4 with respect to the support while maintaining the frame parallel to its former position, a roller 18 supported by a pair of the links 8, the roller being rotatable about an axis perpendicular to the direction of the movement of the frame, and a turning-bar 3 secured to the frame 4 movable therewith and positioned with its longitudinal axis at an angle of 45 degrees to a plane through the axis of rotation of the roller 18 and in a plane parallel to a plane through the axis of rotation perpendicular to the first plane. As shown, the frame is generally L-shaped and is supported at points 9, 10, 11 and 12 by the links 8 pivoted at points 13, 14, 15 and 16 to a fixed support, e.g. frames 1 and 2. The links 8 are of equal length, such that the turning-bar 3 is movable without changing the angle made with a web 17. Alternatively, the frame 4 may be rectangular or H-shaped. The web passes around the turning bed 3 to the top of the roller 18, under a guide roller 27 to a second non- adjustable turning bar 23 fixed between frames 1 and 2. Adjustment of the turing-bar 3 to align the web with respect to a printing press, by movement of the frame 4, causes a proportional movement of the roller 18 in the same direction, thus compensating for the variation in web tension caused by adjustment of the turning-bar 3. The roller 18 is mounted mid-way between the points 10 and 14 and 12 and 16, so that the movement of the roller 18 is half that of the turning-bar 3. The roller 18 is driven through pinion 21 on the roller shaft 19 co-operating with a driven pinion, not shown.
