Title: Improvements in and relating to photosensitive apparatus
IPC: H01H47/24
Filed: 1956-03-15
Abstract: 807,450. Photo-electric cells. GENERAL ELECTRIC CO. March 15, 1956 [March 16, 1955], No. 8135/56. Class 37. [Also in Group XL (b)] A photo-conductive cell for a control device (see Group XL (b)), is formed by applying a thin layer of sensitive material on the inner surface of translucent dome 15 of housing 14 and two spaced electrodes of conducting stripes 32, 32<SP>1</SP> in contact with the layer. The photo-sensitive material may be crystalline sulphide of cadmium or mercury or crystalline selenide of cadmium mixed as a dust with a carrier binder such as varnish or shellac, applied as a thin layer and baked, preferably in vacuo; or the layer may be formed by condensing from vapour, preferably in vacuo. The electrodes are preferably of finely-divided conducting material mixed with a carrier and applied by painting, printing or spraying through a mask; or metal may be vaporized and condensed through a mask. All portions of the stripes and fingers of one electrode are substantially equally spaced from those of the other electrode. Resilient blades 35, Fig. 3, not shown, make contact with enlarged conductive areas 34 on diametrically opposed sides of shell 15. Specification 718,064 is referred to.

Title: Improvements in warp knitting machines and in fabrics made thereby
Inventor: SLADE ARTUR
IPC: D04B27/00
Filed: 1956-03-16
Abstract: 801,450. Knitting. BRITISH NYLON SPINNERS, Ltd. March 13, 1957 [March 16, 1956], No. 8241/56. Class 74 (2). An additional tension bar 21 is positioned between the main tension bar 15 and the guides 17 of the front guide bar of a two-guide bar warp machine. The bar 21 is influenced by a spring which is weaker than the spring controlling the main tension bar so that yarn drawn during the knitting cycle is taken up by the additional bar 21 and is made available and drawn on during the subsequent shogging operations of the guides 17 when the guides are shogged over two needles such that the subsequent knitting operations produce floats. The tension imposed on the yarns during this shogging operation is therefore reduced, resulting in the floats being less taut and capable if being treated to produce a raised surface. The back guides 17<SP>1</SP> receive their yarns for the ground of the fabric over a tension rail 13 in the usual manner.

Title: Improvements relating to in situ building with concrete or the like
IPC: E04G11/18
Filed: 1925-03-27
Abstract: 254,018. Fox, C. J. March 27, 1925. Moulding walls in situ.-Relates to shuttering for use in making building by casting concrete or the like in situ. According to the invention, keys are used for supporting the shuttering, the keys being made of frangible material such as cement or baked clay, and being arranged so that after the completion of one course of concrete they are left embedded in the wall, from which their ends project. The shuttering used as moulds for the next course is supported on these projecting ends, which are subsequently broken off. Fig. 1 shows the frangible keys. used in making a wall such as is shown in process of building in Fig. 2. The outer boards E are supported on the end portions b of the keys left embedded in the course previously completed (or, before the first course is built, on keys laid in the concrete footing). The upper edges of the shuttering, which are held by metal ties M, have notches d, e, f in which another set of keys A are laid. These subsequently support the shuttering for the next course, and also, by projections c thereon, serve to support the inner boards D. Fig. 2<a> shows the use of the keys in making a wall in the construction of which a cavity block N is used. The slots in the shuttering are in this case rather deeper than the keys.

Title: Improvements in or relating to fluidizing agents for lacquers and other film-formingsuspensions
IPC: C09D7/45
Filed: 1959-03-10
Abstract: Sedimentation of pigments and fillers in lacquers is prevented by the addition of a fluidizing agent comprising a solution in an organic solvent of a salt of a basic polyamide with a phosphoric acid or an acid ester derivative thereof, or with an acid diester of a glycol or of a polyglycol.  In Example (1) a basic polyamide formed from dipropylene triamine and ricinenic acid is reacted in a mixture of xylene and butanol with the acid ester formed from equivalent amounts of polyethylene glycol-M.W. 200, castor oil fatty acid and maleic anhydride, and the resultant solution is added to a synthetic resin lacquer containing chrome yellow, Blanc fix, zinc white, linseed oil modified alkyd resin, mineral spirits, turpentine oil, xylene, butanol, a 50% solution of xylenol in dipentene and a 33% solution of cobalt-manganese-lead naphthenate in xylene.  In Example (2) a basic polyamide as in (1) is reacted in a mixture of xylene and butanol with orthophosphoric acid, and the resultant solution is added to a nitrocellulose lacquer containing chrome yellow, barium sulphate, titanium dioxide, nitrocellulose, the monopropyl ether of ethylene glycol, isobutyl glycolate, dibutyl phthalate, ethyl and butyl acetates, butanol, toluene, xylene, ethanol, ethyl lactate, the condensation product of cyclohexyl carbonate with formaldehyde and the condensation product of dehydrated castor oil and phthalic acid obtained in the presence of glycerol.ALSO:A salt of a basic polyamide is prepared by reacting in an organic solvent a basic polyamide (such as that formed from dipropylene triamine with ricinenic acid) with a phosphoric acid or an acid ester derivative thereof, or with an acid diester of a glycol or of a polyglycol (such as that formed by reacting equinolar amounts of polyethylene glycol-M.W.200, castor oil fatty acid and maleic anhydride).  The resulting solution in, for example, a butanol/xylene solvent may be used as a fluidising agent in the prevention of pigment or filler sedimentation in lacquers.

Title: Improvements in and relating to the manufacture of electric cables
IPC: H01B13/30
Filed: 1931-03-18
Abstract: 370,620. Impregnating compositions for electric insulation. FELTEN & GUILLEAUME CARLSWERK AKT.-GES., Mulheim, Cologne, Germany. March 18, 1931, No. 8361. Convention date, March 22, 1930. [Class 140.] To ensure complete impregnation of an electric cable, the traces of air which remain in the cable after evacuation and before impregnation are removed by a non-combustible easily volatilizable liquid which is soluble in the impregnating compound, such as carbon tetrachloride, and. after impregnation the impregnating vessel is again evacuated to remove the volatilizable liquid from the cable. The volatilizable liquid is placed in a container connected to the impregnating vessel containing the cable by a pipe provided with a closable valve which, after evacuation of the vessel, is opened so that the liquid may evaporate and enter the impregnating vessel. After a repetition of these operations, the impregnating compound is allowed to enter the vessel, after which evacuation is again effected.
Patent GB-213915-A (GB)
Title: Safety permutation lock for safes, strong rooms and other purposes
IPC: E05B37/02
Filed: 1924-04-03
Abstract: 213,915. Crets, J. J. C. G. April 3, 1923, [Convention date]. Locks, permutation. - To avoid complicated setting movements in a permutation lock, the bolt-releasing member is controlled by rotatable cylinders arrested in set positions by direct engagement with an adjustable key, on rotation of a spindle in one direction only. The bolt-controlling member 6 is formed as a frame and the upper part rests partially in a recess 5 in a shaft 4 in the bolt-releasing position, being urged into this position by springs 7 compressed between the frame 6 and shoulders 8 on a support 2, when recesses 17 in the hubs 12 of the permutation cylinders 11 are correctly positioned. Locking is effected by lifting the frame 6 so that its upper part is wholly within the recess 5 of the shaft 4, by the eccentric 9 turned by the knob 10, Fig. 1, or by a rack and pinion, and turning the cylinders 11 so that the frame is prevented from downward movement. Setting to align the notches 17 with the top part of the frame 6 is effected by rotating a shaft 18 in a single direction. The shaft 18 has toothed wheels 20 which are made frictionally rotatable with it by means of spring- pressed balls 19 engaging a groove, or by screws. The cylinders 11, which are adjustably secured to the hubs 12 rotating on the shaft 4 by the pawl 15 and ratchet 16, have teeth 14 meshing with the toothed wheels 20, and also have an inclined rib 13 co-operating with the key-bits 27, adjusted at appropriate places along the slotted hollow key-shank 24 by screws 28. When the shaft 18 is rotated, the wheels 20 cause the cylinders 11 to rotate until their ribs 13 successively engage the appropriate key-bits 27, when the cylinders are arrested together with the corresponding wheels 20, the shaft being enabled to continue its rotation to set all the cylinders by reason of the frictional coupling 19. The rotation of the shaft 18 does not require to be stopped at a particular moment since as soon as the cylinders are all correctly set, the frame 6 is moved into bolt-releasing position by the springs 7. Scattering is effected by turning the shaft 18 in the opposite direction after lifting the frame 6, or by removing the key after lifting the frame 6 and continuing the rotation of the shaft in the setting direction. The bits 27 may be replaced by members formed as part of the lock structure and brought to correct position by a dial and pointer device. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the provision for setting the cylinders 11 by sight by forming them with letters instead of ribs on their peripheries. The subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to selective electric networks constituted by band-pass wave filters
IPC: H03H7/01
Filed: 1938-03-19
Abstract: 493,823. Impedance networks. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 19, 1938, No. 8520. Convention date, March 22, 1937. [Class 40 (iii)] In a separator comprising several bandpass filters whose input or output terminals are connected in series or parallel, mutual interaction is neutralized by the insertion of additional reactance arms. The filters a, b, c may belong to the class in which the image impedance is given by R#(1-Y<2>), where Y = (f/fmfm/f)+(f2/fm-fm/f2), f being the working frequency and f1, f2 the cut-off frequencies, while f<2>m=f1f2 and f2>f1. In series with one leg of a tee-section is connected an additional arm A, B or C which is m-derived from the prototype series arm. Thus if the prototype filter a comprises series-resonant series arms and shunt-resonant shunt arms, Fig. 2b (not shown), the impedance of arm A is made m times that of the prototype arm. The sum of the admittances of the networks a+A, b + B, c + C is then approximately real throughout the working range, but in order to provide a closer approximation the common input terminals are shunted by two series-resonant circuits Lm, Cm, Ln Cn. Instead of shuntconnected tee-sections, series-connected pisections may be used, and the arms LmCm, LnCn, are then replaced by shunt-resonant series-connected arms. Alternatively lattice arms may be employed.

Filed: 1958-03-18
Abstract: 879,394. Magnetrons. MULLARD Ltd. Dec. 5, 1958 [March 18, 1958], No. 8657/58. Class 39(1). In an inter-digital magnetron, a plurality of inter-digited members are disposed symmetrically about two coaxial openings one in each planar part of a two-conductor transmission line, alternate members being connected intermediate of their ends to one or other of the conductors. The transmission line is formed from copper strip 10, centrally apertured at 13 and further octagonally apertured at 11 and 12 the members being connected to the midpoints of the longer edges of the octagonal apertures so that when the strip is folded over as shown and mounted inside a glass envelope 18, Fig. 5, the members inter-digitate. The lecher line thus formed is connected to the conductors 15, 19 of a coaxial line, the inner conductor 19 of which is connected to the line 10 at 16 after passing through aperture 13. A cathode assembly 14 is located concentrically of the inter-digitated members, between polepieces 20. When the magnetic field was 1500 Gauss, the device acted as an oscillated at a frequency of 2700 mc/s. and had an output of 200 Watts. The dimensions and relative spacing of all the members are given in the Specification.

Title: An improved construction of race game apparatus for exhibitions, fairs and like places of amusement
IPC: A63F9/14
Filed: 1923-03-27
Abstract: 211,031. Graham, W. J. March 27, 1923. Race, games, mechanical. -The speed of each model in a bicycle-race game is governed by a centrifugal device acting on a conical driving drum, thereby forming an automatic control of the gear ratio between the driving and driven components. As shown, each player pedals a full-size bicycle 2b, the rear wheel of which is connected by a chain 3b to a sprocket wheel 3a mounted on the shaft of a governor 5, through which the motion is transmitted to a conical drum 7. A wheel 9 mounted on the end of a pivoted arm 9<a> is held in frictional engagement with the surface of the drum 7 by a spring 9<b> and is connected by an endless cord to a wheel 9<c>, which serves to drive an endless cord 9<d> to which the model 11 is frictionally attached. The effect of an increase in the speed of pedalling is to cause the governor to move the drum 7 axially against the action of a spring 8 and so to reduce the gear ratio. At the finish of a race each model may be returned to the starting position by a cord 12<e>, Fig. 9, which is wound on a drum 12, mounted loosely on a shaft 12b, by a handle 12d. The connection between the handle and the drum is by means of a crank 12<f> having a projection 12g adapted to engage one of a series of pins 12a projecting from the drum. The crank is normally held out of engagement by a spring 12h.

Title: Improvements in or relating to electric protective systems
IPC: H02H3/00
Filed: 1930-03-19
Abstract: 349,199. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Blake, D. K. ; 314, 5th Street, Scotia, New York, U.S.A.) March 19, 1930, No. 8853. Convention date, March 19, 1929. [Class 38 (v).] A circuit-breaker for disconnecting an A.C. supply from a load circuit is provided with a power directional relay energized from a transformer which has a tertiary winding energized by the voltage of the load circuit and exercising a restraint on the relay, which restraint diminishes with reduced load voltage so that a less amount of reverse power is required to operate the relay under these conditions. Each feeder 3 is connected to the load circuit 1 through a transformer 4 and circuit-breaker 5, the trip coil 12 of which is in series with contacts 22 of a power directional relay 15 having a coil 16 energized by the load circuit voltage and a current coil 17 energized by the secondary 18 of a transformer 19 in the feeder 3. A tertiary winding 23 on the transformer 19 is energized in accordance with the feeder voltage, and is arranged so that a restraint against reversepower operation is provided by it in co-operation with the coil 16. Such restraint diminishes with the drop in feeder voltage so that a smaller amount of reverse power is necessary to operate the relay in such conditions. Thus, when a fault develops in the feeder, the station breaker 6 is tripped by its overload relay, and the reverse current from the load circuit 1 causes the relay 15 to open contacts 21 and close the contacts 22, thereby tripping the breaker 5. The amount of reverse current required to trip depends on the feeder voltage. The de-energized relay 15 returns to its original position in which the closing coil 11 is connected in series with contacts 21, 26, so that when the feeder is restored to normal voltage, the coil 11 recloses the breaker 5. In a modification, Fig. 2 (not shown), a limiting resistance may be connected in series with the coil 17 across the breaker 5 so as to maintain the contacts 21 open until voltage conditions on both sides of the breaker 5 are suitable as regards both magnitude and phase. To prevent the winding 23 affecting the reclosing operation, it may be arranged to be connected in circuit only when the breaker 5 is closed. In an application to a threephase feeder, a polyphase relay energizes the closing coil 11 only when the voltage on all three phases of the feeder is high enough, or a balance relay responsive to voltage conditions on both sides of the breaker may be used for this purpose, operation of the relay in both cases being preferably after a predetermined time-delay.
