Title: Improvements in or relating to electrically heated protective coverings
IPC: B64D15/12
Filed: 1953-11-17
Abstract: 725,125. Electric heating resistances. GOODRICH CO., B. F. Nov. 17, 1953, [Nov. 26, 1952], No. 31839/53. Class 39 (3). [Also in Group XXII] An electrically heated flexible covering especially for de-icing aeroplanes comprises rectangular or trapezoidal sheets 41-43, 45 of natural or synthetic rubber or neoprene or the like superposed to enclose resistance wires 64 extending in parallel in groups to opposite margins where they are connected to flexible conductors 62, 63 so arranged that the heating elements consist of wires in parallel in groups, and the groups are connected in series to give equal heat in each unit. The resistance wires 64 are placed between woven glass sheets 59, 60 with a rubber sheet 61 and are covered by a woven or knitted textile fabric 44 of cotton, silk or glass fibres and embedded in the covering, which is cemented together and to the aeroplane. Thus a wing is protected by several electric heaters 46-48 insulated from one another, the leading edge section 47 being rectangular and preferably heated more than the outer sections 46, 48 which are tapered. In order to ensure unbroken heating at the meeting surfaces of the sections, the outer edges of the heaters are folded downwards and inwards at 54, 55 as in Figs. 3, 16, the dielectric sheets 42, 43 being of such size as to allow space for the inwardly turned parts with their braided supply conductors 62, 63. To make the heaters, a glass fabric sheet 59 is held by tabs 83 on a rotatable drum 75 and the conductors 62, 63 are laid in pairs on strips 85 of Holland cloth thereon (Fig. 7). The resistance wire 64 is then wound on helically from a spool and soldered to the conductors 62, 63. The wires are severed between each pair of conductors 62, 63 along the line 90. A second layer 60 of glass fabric is cemented over the wires to the glass cloth 59, and the layers 59, 60 are severed also between each pair of conductors 62, 63. The heaters may be of tapered form and are then removed from the drum. The ends of the wires 64 are trimmed, the edge of the top sheet 60 being folded back as a flap 60b (Fig. 14). The lower sheet 59 is cut back as shown and a layer 61 of neoprene is adhered thereto. A woven tape 66 is secured at the lower edge of the layer 61 adjacent a polythene strip 95. The conductors 62, 63 are severed and rendered discontinuous by fillers 96 of neoprene between the severed ends, so that groups of parallel wires 64 are connected in series. The tape 66 is then bent forward to the conductor 63 and the flap 60b of the sheet 60 is folded over and cemented to the conductor 63 and tape 66. The polythene strip 95 is removed and the edge of the heater is folded back over itself as shown in Figs. 3, 16. The heaters are then vulcanized to dielectric sheets 41-43 and 45.

Filed: 1975-07-30
Abstract: 1523731 Monitoring micro-wave energy; measuring voltage COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION 30 July 1975 [5 Aug 1974] 31931/75 Heading G1U [Also in Division H4] In a micro-wave alarm device a micro-wave antenna is mounted in or on a rigid body which prevents relative movement between any antenna elements and the body and the antenna is connected to an indicator also in or on the body which operates when the micro-wave energy supplied from the antenna exceeds a predetermined level. For monitoring leakage from micro-wave ovens, the antenna 2 is sandwiched between two layers of cord 6 having a handle portion 6b and an extension 6a defining the distance of the antenna from the oven seal (e.g. 5 cm). The antenna is connected to the filament 5 of a miniature incandescent lamp 4 which may be viewed through a window 7 in the cord and which acts as a threshold detector to the microwave energy if the ratio of filament coil length to length of wire used is within the range 0À1 to 0À4. At these values the coil inductance is low Fig. 2 (not shown) and since when hot it provides a better impedance match than when cold, there is a clear change from dull red glow to incandescence at the predetermined energy level. Other embodiments Figs. 3-4 (not shown) illustrate solid state detectors using hot-carrier diodes and l.e.d. or audible indicators. Reference has been directed by the Comptroller to Specification 1450647.

Abstract: 820,966. Moulding foamed resin articles MONSANTO CHEMICAL CO. Oct. 22, 1956 [Oct. 20, 1955; Nov. 14, 1955], No. 32078/56. Class 87(2). [Also in Group VIII] An article having a layer of foamed synthetic resin with a thermo-plastic sheet on one or both sides e.g. a refrigerator panel, a container or a life belt is formed by placing a particulate foamable resin 10, e.g. polystyrene, on a perforated face 12 of a mould part 20, clamping a sheet 11 of e.g. polystyrene between the mould part 20 and shaped mould part 13, and then blowing steam into a jacket 14 to foam the resin and soften and force the sheet into contact with the mould part 13. Steam is also passed into the jacket 15. To form an article having a sheet of material on each side the foamable resin may be placed between two sheets (see Fig. 4, not shown) or steam may be blown through a pipe 19, Fig. 5, to force the thermoplastic sheet 11 into contact with the mould 13. In a modification (see Figs. 6 to 8, not shown) a thermo-plastic sheet may be preformed to the disired shape before being placed in the mould. A corresponding modification is described (see Fig. 10, not shown) for forming an article having a preformed sheet on both sides of the foam layer. The mould may be heated to such a temperature as to provide glossy surfaces on the thermoplastic sheet. The thermoplastic sheet may be made from methyl or ethyl cellulose, cellulose nitrate, acetate, butyrate, or acetatebutyrate, vinyl halides or other vinyl compounds, acrylic compounds, mixtures of polyvinyl chloride and butadiene-acrylonitrile interpolymers or polystyrene and natural rubber. The foamed resin may be thermosetting or thermoplastic e.g. phenol, urea or melaminealdehyde, methyl cellulose or cellulose acetate, vinyl compositions or acrylic compositions. Other resins are also specified. The foaming agent may be a volatile organic liquid e.g. pentane. An adhesive may be applied to the exposed surface of the thermoplastic sheet to provide a good bond between the sheet and the foamed resin.

Abstract: 1512222 Microprogramming INTERNATIONAL BUSINESS MACHINES CORP 1 Aug 1975 [24 Sept 1974] 32181/75 Heading G4A The address of a group of control words (microinstructions) in a control store 21 is provided by a field 12F of a control word register 12, and one control word of the group read out from store 21 is selected for output, 15, in dependence on a logical combination of machine status signals A, B with a set of signals T1-T8 obtained from a second field 12C of the control word register. The arrangement permits complete flexibility in selection of one control word from a group for a given set of status signals, and elimination of duplicate control words in store 21. It is also possible for two different microprogram routines to call for the same control word under different machine status conditions by suitable choice of the field 12C in each case. The signals T1-T8 are loaded into a BAXR register 11 from the field 12C of a current control word in register 12 when enabled by a field 12B of that control word. Once loaded in register 11, the BAXR bits may be used with subsequent control words in register 12 when selected by a field 12A of those control words, otherwise a predetermined pattern of signals T1-T8 is generated by gates in a block 14. The machine status signals A, B may be derived by masking a plurality of machine condition signals a-s (not necessarily all discrete) with fields 12D, 12E of the current control word in register 12. For complete word selection flexibility, register 11 has N2<SP>N</SP> bits where N is the number of status signals (A, B where N=2). The word selection decoder 13 may comprise 2<SP>N</SP> groups of 2<SP>N</SP> gates, a corresponding gate in each group being partially enabled by the N status signals, and each gate in a group being partially enabled by the same state of a different set of N bits 7.

Abstract: 681,193. Holders for photographic material. GNOME PHOTOGRAPHIC PRODUCTS, Ltd., LOEBSTEIN, H., and ENGELHARD, N. N. Nov. 14, 1950 [Dec. 15, 1949], No. 32191/49. Class 98 (i). A frame for holding photographic sensitive material during projection printing, and having a masking frame hinged to a base-plate, comprises a clamp which locates a sheet of printing paper on the base-plate when the holder is closed or only partly open, and disengaging means which open the clamp automatically when the holder is more fully open. As shown, the baseplate 1 of the frame has a channelled portion 2 formed on one side thereof. A plate 4 overlies portion 2 and rests on its upturned edge 3, being pressed by springs 6 carried by screws 8 fixed to the bottom of portion 2. Plate 4 carries blocks 9 in which a rod 10 is journalled. A U- shaped bar 11, fixed to the rod 10, has extensions 12 which lie beyond the edges of plate 4, and bear, when bar 11 is swung away from the base-plate 1, on a plate 13 on the base of portion 2. This causes the inner edge of plate 4 to be raised from the base-plate. A plate 17 is mounted under plate 4 by an adjustable pin-andslot connection, and a bar 14, with a portion 15 at right-angles to it, is fixed below plate 4. The bar 11 is raised, raising plate 4, plate 17, and bars 14, 15. The-paper is placed on the baseplate so as to be located against bars 14, 15, and bar 11 is lowered. Plate 4 is lowered, bars 14, 15 sinking into channelled portion 2 and into a recess 16 in the base-plate, respectively, and plate 17 presses the edge of the paper against the base-plate. This occurs when the ends 12 of bar 11 leave the plate 13, i.e. before bar 11 is fully lowered on to the base-plate. Plate 17 serves as a border mask for one edge of the paper. The other edges are masked by strips 23, slidably mounted on bar 11 and rod 10.

Title: Improvements in or relating to weighing balances
IPC: G01G17/04
Filed: 1922-11-24
Abstract: 209,897. Dews, S., and Dews, G. Nov. 24, 1922. Taring-devices; loose-weight apparatus. - A weighing-balance is provided with means whereby a series of receptacles of varying weight placed upon a scale pan are balanced by an automatic adjustment made on a second scale pan so that the same conditions prevail as if all the receptacles were of the same weight. Means are also provided to render the adjusting device inoperative and to load the second scale pan with a definite predetermined weight. As shown, the invention comprises a centrally-pivoted beam a having at one end a scale pan b upon which receptacles are placed, and at the other end a support c carrying a master weight e to balance the material to be placed in the receptacle, an annular weight d approximating to the weight of the receptacle, and a liquid receiver l, the contents of which are adjusted to complete the balance of the receptacle. The master weight e is raised from the support c by a plunger f, the lower end of which rests on the surface of a cam g carried on a shaft h and operated by a handle k. If the weight on the support c is insufficient to balance the receptacle, the beam will tilt and a contact spring i, Fig. 4, will rise and complete a circuit with a contact q, thus energizing a magnet o, which varies a valve m and allows liquid to flow from a reservoir w into the receiver l until the beam is balanced when the circuit is automatically broken. Alternatively, if the weight on the support c is too great, a contact j will engage a contact r, thus completing a circuit through a magnet p and allowing liquid to flow from the receiver l into a sump S until balance is restored. Balance having been effected, the operator turns the handle k, which lowers the master weight on to the support and simultaneously by the engagement of cams r<2>, q<2> with levers r<1>, q<1> causes the contacts r, q to be moved respectively downwardly and upwardly out of engagement with the contacts j, i. The substance to be weighed is then poured into the receptacle until the beam balances. Two automatic cut-out switches s are provided to ensure that whichever one of the balancing circuits is closed, the other is rendered inoperative during the remainder of the adjustment. A pump v is connected to the end of the shaft h to return liquid from the sump S to the reservoir w.
