Title: Improvements in toy reinforced-concrete or like construction sets
IPC: A63H33/10
Filed: 1943-03-02
Abstract: 565,534. Building blocks. LAUTENBERG, G. H., and GOUDVIS, S. March 2, 1943, No. 3443. [Class 132 (iii)] [Also in Group V] A toy reinforced-concrete or like construction set comprises a combined coupling and shuttering element, Fig. 9, consisting of a pair of U-section clamps or saddles directed at an angle outwards from each other, so that by fitting the said element within the angle of the adjacent ends of angularly disposed columns, beams or the like, these ends can be held temporarily together and with the aid of further elements or shuttering plates, a shuttering can be constituted around reinforcements projecting from the said ends. As shown in Fig. 1, moulds of various dimensions are built up of a metal base 2 suitably slotted to receive tongues on interfitted strips 11, 13, 17, 18. Reinforcing wires 21 are laced through holes in the transverse strips and strained round projections in the end of the base, and concrete or other mouldable material is poured in and left to set, after which it is removed from the mould and the wires cut to suitable length. In a similar manner, blocks and half-blocks can be made without reinforcement. The precastreinforced beams can be joined to form a T, as shown in Fig. 10, by employing two shutter strips 48 and two shuttering brackets 43 according to the invention. Concrete is poured into the space so formed, and the vertical beam 47 is lowered into position. More complicated reinforced concrete frameworks can be made by the use of more brackets 43 with or without strips 48. Fig. 13 shows the corner of a model building built up of reinforced beams and building blocks 52, the last two blocks being inserted after the removal of the shutters 43 and 57.

Abstract: 265,628. Aero, Motor-und Autozubehor Akt.-Ges. Feb. 6, 1926, [Convention date]. Road-traffic signals on vehicles.-In a direction indicator for motor vehicles of the type in which the signal is actuated by suction from the induction pipe of the engine, the pneumatic cylinder is built into or constitutes the indicator itself. In the arrangement shown, the cylinder b is pivoted to a bracket at h, and its piston c is connected to a cranked arm d pivoted at e. In operation, when the cylinder is connected to the engine suction pipe by a control valve (not shown), the piston is drawn upward and moves the cylinder into the position shown in dotted lines. At the end of its stroke, the piston opens an air-valve i, and the cylinder is returned to normal position by gravity or by a spring. If the control valve is kept open, the indicator will oscillate. A lamp n in the end of the arm is normally covered by a sheath l which is drawn back by a link m as the arm is raised. The end of the arm is coloured to give a signal if the lamp fails, and a prismatic glass o is fitted.

Patent GB-237937-A (GB)
Title: Improvements in the recovery and concentration of nitric acid
IPC: C01B21/46
Filed: 1924-02-11
Abstract: Concentrated nitric acid is recovered from waste nitration acids containing organic matter, simultaneously with the concentration of dilute nitric acid from any source by mixing the latter with the waste nitration acid before it is submitted to the action of steam, in known manner in a denitration tower.  The gases leaving the tower pass through a condenser in which concentrated nitric acid collects and the uncondensed gases pass on to the usual absorption towers. Waste acids obtained in the nitration of glycerine, toluene, and certain dyestuffs and intermediates are mentioned as examples of waste acids which may be used as raw materials.  Preheating of the waste acid before it enters the denitrating tower is desirable in order to increase the amount of dilute nitric acid that can be concentrated and also to reduce the dilution of the effluent sulphuric acid. Further, the more concentrated the effluent acid, the less tendency it has to char when it is heated.  This charring can be partially avoided by the addition of a small quantity of nitric acid, or of the waste acid.  Instead of preheating the acid to be denitrated, superheated steam may be used or a small quantity of concentrated sulphuric acid may be added.

Filed: 1949-02-09
Abstract: 676,870. Arresting broken threads. MULLER, K. Feb. 9, 1949, No. 3553/49. Class 120 (ii) A textile spinning machine has means for retaining a broken thread between the delivery rollers and the spinning head comprising an interceptor rotated at approximately the same speed as the spindle and having means to grip and hold the thread when its tension is reduced due to breakage. One device consists of a twist tube having two plates e, f with eccentric thread apertures and between them a movable thread guide g constrained by centrifugal force to grip the thread between the plates. An alternative device adapted for right-angled feed of the thread has a cap that is spring-urged outwardly from a hollow whirl but normally is held inwardly by thread tension. When the tension is released movement of the cap under spring pressure causes pivoted levers to grip the thread.

Patent GB-446213-A (GB)
Title: Hat cleaning machines
IPC: D06B5/00
Filed: 1935-02-05
Abstract: A dry-cleaning apparatus for hats consists of a bath of solvent in which a hat supported on a former is immersed and moved in the solvent.  Solvent is then withdrawn from the bath and the formers are rotated at high speed in a current of air to remove solvent and moisture.  A casing 10, Fig. 1, is provided with a hat cleaning compartment B, having a dished bottom and a tank D for solvent such as <PICT:0446213/III/1> <PICT:0446213/III/2> trichlorethylene or carbon tetrachloride.  A vertical shaft 11 is mounted in an upper chamber C and extends into the chamber B.  The lower end of the shaft supports a hat carrying member 16 pivoted on pins 19, 20; the lower pin 20 may be withdrawn and the former swung towards the door 78 for loading.  The hat member is formed in two halves connected by a spring controlled member whereby hats of different size are firmly gripped.  A brush 26 contacting with the crown and upper brim of a hat is carried on arms 24 which are attached to a collar 23, and short brushes 27, 28 are pivoted at their ends to arms 24, and are provided with slots 32 engaging pins attached to arms 30.  Solvent is forced by a pump 53 from the tank D through a pipe 52 to the cleaning chamber, and the hat former is submerged therein and either rotated by a motor 68 or oscillated by a motor 69, while maintaining the brushes stationary.  The used solvent then passes through a pipe 54 and filter 55 to the chamber A.  The solvent flows over a perforated plate 50 and falls as a shower through a layer of detergent solution 49 floating on the purified solvent 48.  The solvent may be distilled at intervals.  The detergent solution may be regenerated by passage through the filter 55.  The collar 23 is then lowered to disengage the brushes from the hat; and the former is rotated at a high speed in a current of air drawn by a fan 75 through an inlet opening 74 to an exit 76, whereby the hat is freed from solvent and is dried.  In the cleaning of ladies' hats where brushes are not required, a number of hat formers 41, Fig. 3, are used each mounted on one of a series of arms 24.  The shaft 17 is preferably oscillated during cleaning and then rotated at a high speed to remove the solvent.  The bottom of the chamber 21 is provided with a grooved solid member 46 whereby the quantity of solvent required is reduced.

Title: Improvements in electric cables
IPC: H01B9/06
Filed: 1932-02-09
Abstract: 393,694. Cables. BEAVER, C. J., Bell Place, Stamford Road, Bowden, DAVEY, E. L., 37, Greenway Road, Timperley, both in Cheshire, and GLOVER & CO., Ltd., W. T., Trafford Park, Manchester. Feb. 9, 1932, No. 3842. [Class 36.] To prevent the formation of corona in an impregnated paper cable, the paper is applied about the conductor in such a manners as to leave spaces distributed throughout the insulation which are subsequently charged with a gas under such pressure, substantially greater than atmospheric pressure, that ionization within the gas-filled spaces cannot occur. To ensure that the spaces shall not be filled with free impregnating compound, the impregnation of the paper is effected, prior to its lapping on the conductor, with a compound having a setting point substantially higher than the maximum temperature reached in the working conditions of the cable. Thin lubricating films of highly viscous petroleum jelly may be provided between. the layers of paper lappings. In the construction shown, a stranded conductor 1 formed with a smooth cylindrical surface 2 is lapped with layers of pre-impregnated paper over which is wound a metallized paper layer 6. The layer 6 is preferably perforated. A lead sheath 7, which is reinforced by a helically wound metal tape 8 and protected by an impregnated fabric jacket 9, completes the cable. The smooth cylindrical surface 2 may be formed by using shaped wires in the outer layer of the stranded conductor 1, or by winding a metal tape or foil about the conductor, or a lead tube may be applied over the conductor. Gas spaces 10 are formed in the paper layers by spacing apart adjacent turns of the paper strip and by staggering the turns in successive layers. The spaces may increase in size towards the outer layer, the spacing between the turns and the thickness of the paper strip being graded for this purpose. The Figure shows the insulation of the cable formed in sections 3, 4, 5 having gas spaces of progressively increasing dimensions. The paper strip is preferably lapped on the conductor in air which is kept below normal humidity, and, after the application of the sheath 7, the air enclosed in the insulation is evacuated and replaced by dry air or an inert gas, such as nitrogen or carbon dioxide. The filling of the cable with dry air or gas may be facilitated by a repeated flooding and exhaustion of the gas or dry air into and from the cable and by the application of heat, the gas or air being finally forced in under pressure. In a multicore cable free compound is also excluded from the fillers and the belt insulation. Specifications 20549/14, 182,510, [both in Class 36, Electricity, Conducting &c.], 318,647, [Class 140, Waterproof &c. fabrics], and 373,697, [Group VIII], are referred to.

Filed: 1974-01-28
Abstract: 1460079 Educational appliances J LOGOS 28 Jan 1974 [27 March 1973] 3883/74 Heading G5G A teaching aid comprises at least two groups of items of information 9 distributed over at least two supports such as rigid or flexible strips 6, the items 9 within each group each relating to a different subject such as grammar or geometry, one item relating to each subject being provided in each group, and each group being disposed on one face of its associated support 6. Each item has a checking sign associated therewith, each checking sign being disposed on the opposed face of the support to its associated item of information, the checking signs associated with items 9 relating to the same subject being identical (Fig. 2, not shown). Thus, as shown, one group of items of information 9 is on one strip and relates to eleven subjects, while one item relating to each subject appears, in different positions, on each one of the strips 6. Thus four items of information relating to each of eleven subjects are provided. In use, one item 9 is selected on one strip by framing it in a displaceable slide block 7; slide blocks 7 on the other strips are then moved to choose items related to the subject initially selected. The device is then turned round, and if the selections are correct the backs of the slide blocks 7 will be located over the same checking signs, whereby the accuracy or otherwise of the choice is immediately ascertainable. The strips 6 may be carried by a support member having two uprights 3, or by member having a single upright only (Figs. 5 to 8, not shown). The strips may be of circular form (Figs. 9 and 10, not shown). In other embodiments, the supports for the items of information are constituted by cubes (Figs. 11 to 14, not shown) or cards (Figs. 15, to 18, not shown).

Title: Improvements in or relating to dead locking latch bolts
IPC: E05C1/16
Filed: 1933-02-08
Abstract: 402,276. Night-latches. ROLLINS & SONS (London), Ltd., 4, Stonecutter Street, Faringdon Street, DAWSON, F., 6, Cloister Road, Acton, and WARD, A. F., 93, Grove Park Road, Chiswick, all in London. Feb. 8, 1933, No. 3906. [Class 44.] A night-latch 1 is blocked by the engagement behind its tail 6 of an upstanding lug 18 on a plate 17 when the latter is turned in the direction opposite to that for withdrawing the latch, its movement in this direction being limited by lugs 19 and 14 on the plate 17 and the follower 9 respectively so that the lug 18 is in a dead-centre position with regard to the latch and the plate 17. The latch is thus blocked against withdrawal by the inside handle 10 and by direct forcing. When the plate 17 is turned in its normal direction by the bar 20 of a revolving barrel lock or directly by a key, the lug 19 co-operates with the lug 14 to turn the follower 9 and thus withdraw the bolt. The end plate 6 of the latch is cut away to allow it to pass the lug 18 during this operation. The movement of the latch is limited by the follower engaging with a stop 13 on the casing and by the end plate 6 engaging between lug 7, 8 on the follower as in Fig. 2.

Title: Improvements in or relating to magnetic devices
Inventor: BARNET PETER ALAN
IPC: G11C11/06
Filed: 1962-02-01
Abstract: 972,846. Magnetic storage devices. GENERAL ELECTRIC CO. Ltd. Feb. 1, 1963 [Feb. 1, 1962], No. 3969/62. Heading H3B. -[Also in Division H1]  An epoxy resin adhesive containing ferromagnetic particles is used in the construction of a magnetic storage unit to join the ends of two similar ferromagnetic strip elements 3, Fig. 2, or the ends of a single folded ferromagnetic strip element 5, Figs. 3 and 4. The strip elements may comprise either an 80% Ni, 12% Fe and 8% Mo sintered alloy in which a lengthwise preferred magnetisation axis is produced by grain orientation during manufacture, or an electrically deposited film of 95% Ni and 5% Fe in which a preferred magnetisation axis is produced by polarisation during the deposition process. The epoxy resin adhesive is loaded with fine particles of an 82% Ni, 18% Fe powder or powdered mumetal, and is polarised during the curing process by a magnetic field component vertical to the strip element surfaces united by the resin. Consequently, a preferred axis is established in the cured adhesive which completes the preferred flux axis around the storage units. Alternatively, in the Fig. 2 embodiment, the polarising field may be produced by currents in the co-ordinate conductors 1, 2 of a matrix store. Details are disclosed of constructing a matrix store, Fig. 1 (not shown), in which the elements of Fig. 2 are used. This subject-matter is identical to that disclosed in Specification 972,845, and comprises the basic step of applying long ferromagnetic strips, one of which is coated at intervals with the loaded adhesive, diagonally and on opposite sides of a matrix of insulated conductors 1 and 2. If the ferromagnetic strip elements are too thin to be self-supporting, they may be formed on a flexible non-magnetic tape of polyethylene terephthalate. The units shown in Figs. 3 and 4 may be formed by wrapping ferromagnetic strip lengthwise around a mandrel, bonding the overlapping portions, slicing into elementary strips, and removing the mandrel by dissolving.
