Title: Improvements relating to marking apparatus
IPC: H01B13/34
Filed: 1961-07-20
Abstract: 920,318. Marking curved surfaces. J. C. GEMELLI. July 20, 1961 [Oct. 21, 1960], No. 26352/61. Class 100 (2). The insulating covering of a wire 26 travelling in a vertical direction is marked with three continuous spiral stripes, which may be of different colours, by three inking members mounted on a belt-driven rotor 38 rotating about an axis coincident with the longitudinal axis of the wire. The wire is guided in its vertical path by a stator 20 which is secured to the horizontal base 22 through which the wire passes and carries a guiding member 28. The stator, which is bored to accommodate equiangularly spaced ink-conducting connectors and passages 32, 30, 36, mounts the rotor 38 on ballbearings 40, 42 whilst the rotor itself is bored to provide passages 48, 46 through which the ink is conducted from the associated connectors and passages in the stator to inking members 74 or 76 housed in a rotor head 62 which is bolted to the rotor. The ink passes from the stator passages 36 to the rotor passages 48 through annular passages 54 located between the stator and rotor, such passages being delineated by annular channel members 52 secured to the inner wall of the rotor. Each member 52 accommodates a leather sealing strip 56 which is held against the stator by a spring steel strip 58, any ink leakage from a passage 54 into the associated members 52 causing the seal to function more effectively. The marking of the wire may be effected by inking nozzles 74 or inking wheels 76 as required, the needle-valve controlled and longitudinally adjustable units 72 carrying the nozzles or wheels being interchangeable in the one head 62. A rotor head 90 (not shown) may be used which is only capable of mounting inking nozzles. The invention is not limited to three inking members and it is not necessary to space the inking members equi-angularly around the rotor head. The channel members 52 may be fixed to the stator instead of the rotor, each sealing strip 56 in this case bearing against the rotor.
Patent GB-710136-A (GB)
Title: Process for manufacture of filaments
Inventor: JAMSETT RONALD ALFRED
IPC: D01D5/092
Filed: 1951-11-10
Abstract: A molten synthetic linear polymer is extruded through a spinneret to form a bundle of filaments which pass down a cooling shaft, and fluid cooling medium is caused to flow across the cooling shaft and impinge on a baffle plate positioned close to that side of the filament bundle remote from the cooling medium inlet and extending vertically over at least one-third of the length of the shaft.  The distance between the baffle plate and the nearest filaments is advantageously made as small as possible consonant with a safe margin of separation to ensure that no accidental collision can occur due to any slight vibration of the filaments.  This distance of separation may be from 0.5 to 2 inches.  The cooling shaft may be rectangular and the side of the shaft constituting an inlet for the cooling medium, e.g. air, may consist of the open mouths of ducts or preferably may be in the form of a screen or other foraminous surface, to ensure the production of a steady cross-current.  The baffle plate may completely close laterally that portion of the side of the cooling shaft over which it extends, but preferably one or more openings of small area are left in the lateral edges of the plate so that the closure is not complete.  The filaments running down the shaft are blown by the cross-current of cooling medium so that they follow an arcuate path.  The baffle plate may be shaped to conform with the contour of the arc described by the filaments and it may also be shaped to conform with the contour of the cross-section of the filament bundle so that the nearest filaments are separated from the plate by a nearly constant distance.  The baffle may be made of steel, aluminium, tinned iron plate, or glass.  The synthetic linear polymer may be a polyester, polyurea, polyamide, polyurethane, or a polyanhydride, e.g. polyaminononanoic acid, polysebacic anhydride, polyhexamethylene sebacamide, polyglycol terephthalate or polyhexamethylene adipamide.  The provision of the baffle plate improves the cooling and steady running of the melt-spun filaments as they come from the spinneret in the form of a bundle.  In an example, nylon is melt-spun through a spinneret provided with orifices which are arranged in a square lattice pattern and the filaments pass down a rectangular cooling shaft 40 inches long in which is a cross-current of air flowing at 150 cu. ft./min.  The side of the shaft opposite the air inlet is provided with a baffle plate 22 inches long, positioned at a distance of 1 inch from the bundle of filaments, and reaching to within 2 inches of the top of the shaft. Specification 533,304 is referred to.

Title: Alumina gels
Inventor: WILSON CHARLES PATTON
IPC: C01F7/141
Filed: 1965-06-23
Abstract: Alumina gels are produced by contacting a solution of an alkali metal aluminate with a strong mineral acid to form a slurry, spray drying the slurry, washing and drying the spray-dried product, the ratio of aluminate to mineral acid being such that in the presence of the mineral acid but in the absence of any pH correcting agent added per se the pH of the slurry would be in the range 4.5 to 7.0.  The strong acid may be sulphuric, hydrochloric or nitric acid, the sulphuric acid being a 15-30 weight per cent solution. The alkali metal aluminate is preferably sodium aluminate and may contain 65 to 150 gm./l of aluminium oxide. The aluminate and acid may be mixed rapidly to produce a low density gel and the preferred pH range of the slurry is 4.7 to 6.0.  The spray-dried product is washed until the alkali metal content expressed as alkali metal oxide is less than 0.05% by weight.  This washing may be carried out with a 2 DEG  Baum<\>ae ammonium sulphate solution, with a further rinsing with ammonia water, both solutions being at a temperature of 43 DEG  C.  The precipitate may be flash-dried after washing.  The alumina gels have a mercury pore volume of 1.5 to 3.5 cc./g., a nitrogen pore volume of 0.60 to 1.3 cc./g. and a compacted density of 0.22 to 0.40 g./cc.

Title: Automatic telephone and like signalling system
Inventor: OBERMAN ROELOF MAARTEN MARIE
IPC: H04Q3/00
Filed: 1952-10-24
Abstract: 762,273. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Oct. 24, 1952 [Oct. 27, 1951], No. 26812/52. Class 40 (4). In an automatic exchange system in which a marker first obtains the identities of the calling and called subscribers and then obtains information as to the busy or idle condition of all inter-switch links which could complete the connection, a trunking system of the type illustrated in Fig. 2 is employed. Thus in an exchange having 9,000 local lines and outgoing trunks over the " O " level, each 2000 line group is divided into 40 sub-groups of 50 lines, each sub-group being multipled over a group of ten primary switches, which are crossconnected to 10 incoming secondary switches whose ten outlets are connected to " cord " circuits. These in turn are cross-connected to outgoing secondary switches respectively giving access to each group of 2000 subscribers via primary switches. The latter may be the same switches as are used for incoming traffic. In this case if cross-bar switches are used, both incoming and outgoing secondary switches may be combined in one cross-bar switch having identical connections on the primary switch side, but different connections on the " cord " circuit side. Method of setting the switches, Fig. 3. A calling subscriber obtains access to a register REG, which receives the identities of the calling and called subscribers in known manner. The control circuit then seizes a marker and transfers this information thereto. The marker then sets the switches MSA, MSB and MSC over which are obtained the busy-or-idle conditions of the 10 incoming primary-secondary links, the 10 outgoing primary-secondary links and the 20 'cord " circuits capable of setting up the connection. The marker then uses this information to assign a free route and seizes, over switches MSD, MSE, control circuits for controlling the switches which will effect the connection over the desired route. The control circuits are then fed with setting information for the switches which are then set accordingly to complete the connection. Specifications 747,173 and 750,139 are referred to. Reference has been directed by the Comptroller to Specification 679,544.

Abstract: 519,196. Type-printing telegraphy. CREED & CO., Ltd., and SALMON, R. D. Sept. 16, 1938, No. 27085. [Class 40 (iii)] A printing telegraph receiver has means for making a record for subsequent re-transmission comprising code discs mounted for rotation with the type-wheel and selector members cooperating with the code discs to operate punches or other recording members. The shaft 1 carrying the type-wheel has fitted to it a number of code discs 2 of which two only are shown. At each printing operation the printing bail 3 depresses a frame 7, pivoted on a shaft 8, by means of an arm 4 and link 6. The outer ends of selector members 10 carried on a pin 9 fixed to the frame 7 are therefore depressed. Each selector member co-operates at its other end with an individual code disc 2 and if this latter end is held by a projection on its code disc the depression of its outer end causes its punch 12 to be forced through a paper tape 18. If it is not held by a projection of its code disc, a selector member 10 pivots about its point of connection 17 with its punch and the latter is not operated. The tape is fed forward after each punching operation by a feed wheel 21 rotated by a feed pawl 14 itself actuated by the arm 4 on the printing bail 3. The invention is suitable for use with a printer of the kind described in Specification 468,839, [Group XVI].

Title: Rotary impact tools
IPC: B25B21/02
Filed: 1957-08-29
Abstract: 851,370. Screwing-up and unscrewing nuts &c. ARO EQUIPMENT CORPORATION. Aug. 29, 1957 [Dec. 31, 1956], No. 27218/57. Class 83 (3). [Also in Group XXIV] An impact-wrench comprises a shaft P driving a hammer H, an anvil A, and means I, D<1>, D<2> for clutching the hammer to the shaft P and the anvil respectively. An air-motor 22 drives through splines 28, the shaft P, which supports the hammer on a bearing-sleeve 32. Axial passages in the hammer house the hammer dog I, which is movable axially by engagement between a flange 58 on the dog and a cam-groove 56 in the shaft P, and the hammer-driving pins D<1>, D<2>, which may enter a cam-recess 64 in the anvil, thus freeing the hammer by moving out of engagement with a driving-lug 53 on the shaft. The pins D<1>, D<2> comprise an outer sleeve 68 and a stem 70 held within the sleeve, against the influence of a spring 78, by a pin-and-slot connection 72, 74, a spring 76 biasing the pins against the anvil. Before the torque demand increases, the anvil is driven without impact and the members of the drive are in any of three conditions. In the first two conditions, the hammer may be driven positively, Fig. 10 and Fig. 8 (not shown), by engagement between either pin D<1> or pin D<2>, and the driving-lug 53, and drive the anvil frictionally by engagement between the cam 64 and the pin which is not engaged by the lug 53. In the third condition, the hammer is driven frictionally, through contact between the hammer dog I and cam 56, and drives the anvil positively through contact between the dog I and an impact shoulder 62 on the anvil. This condition is reached about 60 degrees clockwise of that at impact, illustrated in Fig. 6. Before impact, the anvil is held by an increase in torque demand, and the operative hammerdriving-pin D<2>, following the cam 64 on the anvil, withdraws from the driving-lug 53, thus de-clutching the rotating hammer from the driving-shaft before its dog I strikes the anvil shoulder 62. The hammer is then held by the anvil until continued rotation of the shaft P, and thus of cam 56 and lug 53, de-clutches dog I from shoulder 62 and again rotates the hammer, by contact between lug 53 and the pin D<1>. After one revolution of the lug 53 from. the impact position of Fig. 6, the hammer has turned through about 120 degrees, when it is again de-clutched, by pin D<1> entering the camdepression 64. The resulting relative rotation between the shaft P and the stationary hammer, to the position depicted in Fig. 10, extends the hammer dog I from the hammer and allows the lug 53 to again contact pin D<2>, which it drives to complete the impact cycles. Thus the shaft P completes two revolutions, for each revolution and hammer blow of the hammer member. A greater number of revolutions per hammer blow can be obtained by using more hammer-driving-pins D. The wrench may be operated in the reverse direction for removing nuts.
