Title: Improvements in toys
IPC: A63H33/42
Filed: 1935-11-04
Abstract: 465,468. Toys. GAUNT, C. F. Nov. 4, 1935, No. 30388. [Class 132 (iii)] A metal blank 10 has representations 11, 21, 25, which may be embossed, marked on it which are weakened around part of their outlines by spaced slits 14, perforations, scoring or partial cutting and are pressed up out of the plane of the blank to form upstanding objects. The house 21 remains attached to the blank 10 along the line 15 and after being pressed up is bent along the weakened lines 22. A conical or multi-sided tent may be similarly formed. The objects may be provided with a marginal tab or tabs 23 for engagement in an opening or openings 24 in another portion of the object or in the body of the blank. The blank 10 may be superposed on a sheet 18 of printed tinplate, cardboard, paper, green felt, or other fabric of darker colour to give the effect of shadows of the upstanding objects. The undersheet 18 may consist of or incorporate a piece of clear or coloured glass or a mirror which appears through openings in the blank 10 to simulate pools of water. As applied to a model theatre the undersheet 18 forms the stage and a number of interchangeable blanks 10 form the scenery. Fixed and loose scenic elements moved about by long tweezers can be provided. The loose elements of sheet metal are provided with a supporting tab or tabs 27, Fig. 2, or a stem or stems at the base engageable in circular holes 28 in the blank 10, or a tab 30, Fig. 3, engageable in the holes 28 which tab may be directed downwardly and its edges bent to form a part cylindrical or cylindrical stem if the undersheet 18 is omitted, or may be formed by pressing out of the plane of the blank 31 a representation 32 connected to the blank around part of its outline by spaced slits 33, perforations or scored lines. The undersheet 18 may be of sheet metal bearing objects similarly to the blank 10 and extending through openings in the blank 10. The blank 10 may simulate grass or sea-waves by suitable colouring and embossing. Specifications 437,813 and 446,899 are referred to.

Title: Device for regulating the transmission of a vehicle incorporating a continuously variable gear and a reverse gear
IPC: F16H61/662
Filed: 1976-07-21
Abstract: 1498393 Change-speed control AUTOMOBILES CITROEN SA 21 July 1976 [30 July 1975] 30462/76 Heading F2D In a continuously variable motor vehicle transmission in which a ratio-control element is positioned by an hydraulically actuated device under the control of a distributor actuated by an engine-driven centrifugal governor opposed by resilient means adjusted by the vehicle engine accelerator, an electrically operable valve in a discharge line from the hydraulically actuated device is closed when the accelerator is released to prevent the transmission from being adjusted to high ratio. Decreasing engine speed influencing the governor 15, or increased depression of the accelerator 20a acting through a cable 20 and lever 19 on a loading spring 18, causes movement of the distributor 10 to the position shown in which a pressure source 12 is connected to a conduit 8 to pressurize a chamber and cause a piston 5 to move a ratio adjusting member 2 against biasing means (not shown) in the direction for reducing the transmission ratio, whereas increase of engine speed or reduced depression of the accelerator causes the distributor to move to a position in which it exhausts the chamber 7 through a conduit 91, normally open valve 22 and conduits 92, 9a to raise the transmission ratio, the distributor ultimately returning to a neutral position in which flow to or from the chamber 7 is blocked. Release of the accelerator causes a cable 27 and lever 26 to close a switch 24 and thereby energize a relay 25 to cause actuation of the valve 22 to interrupt communication between the conduits 91, 92 so that the transmission is not adjusted to high ratio, thereby facilitating town driving. The valve 22 is also actuated through a relay 30 on closure of a switch 29 when a member 31 is moved to select reverse drive. With the engine idling when reverse is selected the piston 5 will be positioned for low ratio and this position will be held due to the closure of the valve 22. In a modification the accelerator responsive switch 24 is actuated also by the forward-reverse selector, the relay 30 and switch 29 being dispensed with.

Title: Improvements relating to the construction of reinforced concrete floors
IPC: E04B5/32
Filed: 1937-11-06
Abstract: 505,493. Floors; reinforced concrete. POULTER, J. H. Nov. 6, 1937, No. 30475. [Class 20 (iv)] Relates to a reinforced-concrete floor of ribbed type in which the reinforcements comprise metal structures of arch or approximately inverted-trough cross-section disposed side by side. According to the invention, the reinforcements are constructed of longitudinal rods or bars 9 and transverse rods or bars 8 bent to the desired cross-section of the reinforcements, the bars 8, 9 being appropriately spaced and connected together by clips, wires, welding or other suitable means to constitute openwork structures which are of sufficient strength to carry the constructional load and the temporary shuttering on which the fioor is cast. The transverse members 8 are bent to form feet 8a, and the longitudinal members 9 are provided along the base and near the top of the vertical side portions of the transverse members 8 ; if desired, longitudinal rods 9 may also be arranged along the top portions of the transverse members. The reinforcements, which are adapted to be supported at their ends on the walls of the building, may be arranged with the feet 8a of adjacent reinforcements in abutting, overlapping or staggered relation. The feet 8a of adjacent reinforcements may be wired or clipped together, or the foot of one reinforcement may be connected to the lower longitudinal rod 9 of the adjacent reinforcement. The shuttering 11 is suspended from the upper parts and the feet 8a of the transverse members by wires 12. Wires 12a or other members may be attached to the lower longitudinal rods 9 and depend through the shuttering for the subsequent support, after the concrete has been cast, of spars 13, Fig. 4, for carrying a coiling 14. Wires may be connected between the depending portions of each transverse member or preventing such portions spreading apart when the concrete is cast.

Title: Improvements in and relating to apparatus for measuring viscosity
IPC: G01N11/12
Filed: 1935-11-04
Abstract: 459,565. Viscosimeters. BEALE, E. S. L., 44, Markham Square, Chelsea, London. Nov. 4, 1935, No. 30507. [Class 106 (ii)] In a viscosimeter of the " falling sphere " type, the spherical element 7 is fixed to the casing 5, and the oil-containing bucket 6 constitutes the timed falling-element. A water bath 3 and thermometers 4, 10 are provided, and when the latter indicate the same temperature a supporting member 11 is moved by a handwheel 14 clear of its seat 12, and is held in that position by a catch 15 pivoted at 17. When the catch is moved, the parts 11, 13, 14 fall away from the bucket 6 until a button 18 on the part 14 engages a blade 19 of an electric switch, and forces it into contact with another blade 20 to close a circuit for producing an indication upon a moving photographic film or tape 23. As soon as the enlarged upper part of the bore of the falling bucket 6 reaches the great circle of the ball 7, the bucket falls rapidly on to the member 11, transmitting a second blow to the contacts 19, 20 and producing a second mark on the travelling film or tape. The indicating-means 22 may take the form of an electrically-controlled clock, in which case no film or tape is required. Both ball and bucket are preferably made from the same steel billet. Hardened stainless steel may be used for these parts. In a modification the falling bucket 6 is located in a considerably larger vessel containing the same fluid as the bucket. Alternatively the bucket may be located in a cylindrical space in a large solid block of copper maintained at constant temperature. In another modification, the blow transmitted from the falling bucket is used to rotate gearing to stop a clock indicator, which was previously started by a device releasing the catch 15.

Title: Improvements in and relating to holders for cigarettes and cigars
IPC: A24F13/08
Filed: 1923-12-04
Abstract: 211,102. Hendler, O. Feb. 10, 1923, [Convention date]. Cigar and cigarette holders.- After insertion into the holder b the cigar or cigarette is resiliently held by a sleeve e of rubber or the like. The sleeve is thinned down at its inner end, where it engages a conical seating f in a fitment c. A cap d screwed upon the member c has a shoulder i abutting against the sleeve e, so that screwing down the cap d causes the lower end of the sleeve e to grip the cigarette or cigar. The fitment c may be dispensed with and the conical seating f formed in the holder itself. In this case the cap d is provided with a longitudinally-slotted sliding sleeve which engages the exterior of the holder resiliently. The outer end of the cap may be turned in over the end of the sleeve e. In a further modification, the cap d is screwed upon the holder b and the sleeve e replaced by a resilient ring of approximately circular cross-section which is compressed between the shoulder i and the end of the holder. A pad of wadding may be placed in the space a.

The tubes may be arranged in two layers 3, 4 one above the other, and the bulbs planted in carriers 7 placed between. The tubes may be connected as by flexible couplings 5 to a feed pipe 1 at one end and to an outlet pipe 2 at the other. The refrigerating agent may be water aspired out of a Norton tube and driven through the tubes by a pump 6. The tubes of the upper layer may be so placed that they may be readily disconnected and lifted.
Patent GB-306150-A (GB)
Abstract: 306,150. British Tabulating Machine Co., Ltd., (Assignees of Bryce, J. W.). Feb. 16, 1928, [Convention date]. Sorting cards. - A record-card - controlled machine in which the cards are read by electric brushes, is supplied with alternating current which falls to zero synchronously with the separation of the brushes from the contact cylinder by the trailing edges of the card holes. The current may also be zero at the leading edges. The armature 21 of a generator is driven syn. chronously with the card feed devices 27, 26 by a motor 20 through a coupling 25 which is adjustable for correct synchronization. The armature 21 is tapped so that a commutator 22 supplies D.C. to the control circuits 11, 13, and slip rings 24 supply A.C. to the circuit 17, 18 for the brushes 6 and counter magnets 5. Whilst the machine is running correctly the card ..control circuits maintain contacts 16 closed so that A.C. is supplied which is zero at the moment the leading and trailing edges of the cards separate the brushes 6 from the contact plate 7. A commutator switch 28 is also used in series with the slip rings 24 so that sparking is avoided even if the brushes become out of position. The magnets 5 may control registering, sorting, listing,. or other operations.

Title: Furnace for sintering, roasting and firing
IPC: F27B1/08
Filed: 1930-10-14
Abstract: 364,698. Shaft furnaces. VEREINIGTE STAHLWERKE AKT.-GES., 69, Breitestrasse, Dusseldorf, Germany. Oct. 14, 1930, No. 30776. Convention date, Nov. 6, 1929. [Class 51 (ii).] A shaft furnace for sintering, roasting, and burning bricks or refractory material is provided with supply and discharge pipes so arranged that gaseous fuel may be supplied at the bottom, the draught being upwards, or solid fuel may be supplied at the top, the draught being downwards, either fuel being used according to the material to be treated or the fuel which is available. The furnace shown comprises a tapering casing 2 with a discharge duct 8 at the bottom from which extends an inclined discharge duct 9 with a valve 10 and gas seal 11, and also a vertical discharge pipe 12. Pipes 4 connected to the duct 8 serve for supplying gas and air or alternatively for discharging combustion products when solid fuel is used. When gas' firing is employed, the combustion products are drawn off by a fan 6. The furnace is provided with sight-holes 7 in the top cover, and with doors 13 in the side which serve to admit cooling air and also for emptying the furnace when it contains, for example, clay or bricks.

Title: Exposure meter for electron microscopes
IPC: H01J37/22
Filed: 1954-10-26
Abstract: 758,240. Electron microscopes. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 26, 1954 [Nov. 4, 1953], No. 30817/54. Class 39 (1). The fluorescent coating of the viewing screen of an electron microscope is earthed via a current measuring device and provides a measure of the exposure necessary for a photographic film or plate. If the conductivity of the fluorescent layer is low, the glass support is first coated with a thin transparent conducting layer, e.g. of gold. The current from the screen is passed to a high resistance 2 and the voltage across it is amplified in the cathode follower valve 3, 9 and recorded on measuring instrument 11. In an alternative method, the time of exposure is controlled by providing an R.C. circuit connected to point 16 between resistances 61, 6<SP>11</SP> which can be connected to the grid of the valve 3. When switch 15 is operated, the grid receives the potential of point 16 which gives full deflection at instrument 11, and as the condenser 14 charges the deflection falls slowly to zero. By suitable design of the condenser and the resistances, the time taken to fall to the original deflection given by the microscope is the true exposure time and the microscope is switched on and off at these points.

Title: Improvements relating to electric transformers
IPC: H01F38/08
Filed: 1931-11-06
Abstract: 392,193. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, MAYO, C. G., 17, Alexandra Road, and MATHEWS, P., 7, Bilton Rise, both in Rugby. Nov. 6, 1931, No. 30829. [Class 38 (ii).] The regulation of a transformer is improved by providing a magnetic shunt between the primary and secondary windings, the shunt being designed to be saturated under all operating conditions. The flux therein is thus of constant magnitude but becomes phase displaced with respect to the main flux linking the secondary winding when load current of other than zero power factor flows whilst at no load both fluxes are in phase. Thus the flux linking with the secondary is smaller (by an amount equal to the shunt flux) than the total flux linking with the primary at no load, and increases with load current to maintain the same resultant flux linking with the primary as the shunt flux becomes displaced in phase. Figs. 1 and 2 show alternative ways of arranging the magnetic shunt a and primary and secondary windings b, c. In a further form, the shunt path may be formed by a separate core.

Title: Improvements in or relating to continuous spinning frames for the wet-spinning of artificial filaments
IPC: D01D5/06
Filed: 1964-08-04
Abstract: 1,037,130. Wet-spinning apparatus. STUDI E. BREVETTI APPLICAZIONI TESSILI S.R.L. Aug. 4, 1964 [July 26, 1963], No. 30856/64. Heading B5B. Apparatus for the wet-spinning of artificial filaments, particularly cellulosic filaments and especially viscose rayon, comprises, in combination with any spinneret 12 and spinning solution supply means 10, 11, a substantially vertical spinning conduit or tube 14, within which the extruded filaments are dragged downwards by the bath, a second substantially horizontal spinning tube or conduit 16, substantially at right-angles to the first one, means 18, 19 for discharging the bath at the outlet of said horizontal spinning conduit or tube, and an accumulating and forwarding device 21 (suitably comprising a treating roll 22 and four forwarding rolls 23) for the withdrawal of the thread separated from the bath, upwardly from said horizontal spinning conduit or tube through a vertical tube 20 in which the portion of both withdrawn by the thread drips off and is discharged together with the main portion of the bath. The accumulating and forwarding device may be associated with a plurality of spinnerets, and therefore, a plurality of vertical and horizontal spinning tubes. A spinning-frame unit may comprise one such accumulating and forwarding device and at least four spinnerets and the conduits associated therewith. In the zones where the threadpath passes from a vertical direction to a horizontal direction and vice versa there may be arranged means for causing friction on the thread so as to localize a substantial part of the stretching caused by the dragging effect of the bath and the withdrawal of the thread by the accumulating and forwarding device. Such means may comprise nozzles 24, Fig. 4, 36 (Fig. 5, not shown), of suitable material resistant to wear on the lip of which the thread slides in changing its direction of movement. Such materials may have a hardness of 7À5 or more on the Mohs scale and a coefficient of friction of 0À20-0À25. Specified materials are carborundum, zirconium titanate and synthetic ceramic materials containing a high percentage of aluminium oxide. The nozzles are desirably housed in angles 27, Fig. 4, 17 (Fig. 5, not shown), of lead or other chemicallyresistant material, and angle 17 as shown in Fig. 5, not reproduced, is suitably connected with a tube 18 opening into a collector 19 for the elimination of the bath.

Title: Blasting Machine
IPC: H03K17/28
Filed: 1967-07-05
Abstract: 1,186,070. Control circuits for electric detonators. INSTITUT NATIONAL DES INDUSTRIES EXTRACTIVES. 5 July, 1967 [6 July, 1966], No. 30940/67. Heading H2H. Blasting apparatus comprises safety devices whereby the blasting circuit is disabled should the resistance of the line of serially connected detonators be too high or too low or should the supply to the detonators persist after a given time limit. A line of serially connected detonators are connected to terminals 7, 8 supplied by high-voltage lines 5, 6; the high voltage being derived from a low-voltage battery 1 by way of a transistorized current converter 3; the output of the converter 3 being connected to the lines 5, 6 by a switch 9 when a capacitor 4 reaches a predetermined level of charge. The switch 9 is preferably a thyristor controlled by the charge in the capacitor 4 by way of a trigger circuit 10. The safety devices comprise transistorized trigger circuits D, E, F each of which functions to trigger a switch 11 into conduction by way of a control circuit C. The switch 11 is preferably a second thyristor which, when conductive, short-circuits the 'line of detonators. The current flowing through the thyristor 11 is limited 'by a resistor 12. The trigger circuit D produces an output signal if the resistance of the line of detonators is too high-an open circuit, for example-the circuit F produces a signal if the resistance of the line of detonators is too low such that too much current would be flowing in the detonator circuit and the circuit E produces a signal a predetermined time-say 4 secondsafter the supply to the detonators has been established by conduction of the thyristor 9. A resistor, short-circuitable by a push button switch, is placed in series with the terminals 7, 8 to allow the circuit to be used with a variable number of detonators.
