Abstract: 413,243. Indexing. JONES, J., Noddfa, Warren Drive, Deganwy, Carnarvonshire. Feb. 23, 1934, No. 6023. [Class 16.] A book, periodical, newspaper, or any arrangement of flexible sheets where more than two sheets are employed has one or more portions cut out in one or more edges of some or all of the sheets, these portions being arranged to form at least one or at least two series in such a manner that when the thumb is pulled over the edge where the portions are cut away the sheets will turn over in pairs or in sets of three or more. Sheet A of a book has a cutout portion or bay a at a position opposite the numeral 3 on page 3 of the next sheet B, and the bay b in the sheet B is adjacent to the bay a opposite the numeral 2 on page 2 of the sheet A. This arrangement is continued throughout the book so that the bays in the sheets A, C, E &c. are opposite to each other and form one series of bays, and the bays of sheets B, D &c. form another series of bays. Instead of page numbers being visible through the bays, there may be arranged other indications, such as titles and chapter or page numbers. The bays may be differentiated by colour applied around the edges thereof. More than two series of bays may be provided in which the sheets are turned over in pairs, or in sets of three or more. Instead of bay-shaped cut-out portions the upper and lower corners of alternate sheets may be cut away, the cuts on alternate sheets sloping in opposite directions. The parts adjacent the bays or cut-out portions may be reinforced or coloured to prevent numerals or other indications being visible through the pages, particularly where thin transparent paper is used.

Patent GB-485794-A (GB)
Title: Improvements in or relating to aircraft
IPC: B64C13/00
Filed: 1937-03-04
Abstract: 485,794. Controlling aircraft. BACK, W. E. March 4, 1937, No. 6479. [Class 4] In an aircraft comprising a main plane with two ailerons hinged thereto and a tail elevator, or two main planes without appreciable stagger of which either or both are provided with two hinged ailerons, a pivoted main control member is adapted to move the ailerons differentially and when moved in the fore and aft direction about its pivot to move the ailerons together and simultaneously to impart movement in the opposite sense to the elevator, a separate control being provided whereby the pivot of the main control may be moved to move the ailerons together in the same sense without causing appreciable movement of the tail elevator. When the main planes are considerably staggered only the ailerons of the forward plane are moved oppositely to the elevator and those of the after plane are moved in the same sense. In the last form a wheel control comprises a wheel 9 carried by a column 10 fast with a transverse spindle 19 mounted for vertical rocking movement by crank arms 45, 46 on a shaft 43 rotatable by hand lever 42. Wheel 9 is geared to a sleeve 13 surrounding column 10 and carrying at its lower end a pinion 14 meshing with similar pinions 15, 16 on sleeves 17, 18 carried by spindle 19. Two-armed levers 20, 29 carried by sleeves 17, 18 respectively are connected by the linkage shown to levers 23, 24 and 32, 33 fast with pulleys 25, 26 and 34, 35 respectively. Pulley 25 is connected to port upper aileron 6, pulley 34 to the starboard upper aileron, pulley 26 to starboard lower aileron and pulley 35 to port lower aileron 7. Spindle 19 also carries levers 38, 39 respectively connected bv links to a tail elevator. Thus fore and aft movement of the wheel causes both elevator and aileron movement, the movements of the elevator being opposite to those of the upper ailerons and similar to those of the lower ailerons. Rotation of the wheel causes differential movement between port and starboard ailerons. Rotation of shaft 43 by hand lever 42 causes simultaneous movement in the same sense of all the ailerons, the elevator remaining unaffected. In a modification, Fig. 3, a control column is universally movable on a ball 46 movable up and down by hand lever 47, the column being fast with a fore- and aft shaft carrying double-armed levers connected by links to levers associated with pulleys around which pass cables operating the control surfaces as in the above-described arrangement. Specification 462,382 is referred to.

Filed: 1941-05-22
Abstract: 547,372. Aromatic amine-aldehyde resins. WINGFOOT CORPORATION. May 22, 1941, No. 6588. Convention date, July 18, 1940. [Class 2 (iii)] [Also in Group V] Rubber is vulcanized in the presence of an age-resistor, made by reacting a di (arylamino) methane with a diarylamine in the presence of a strong inorganic acid e.g. hydrochloric acid at 65 to 100‹C. The methane compound may be methylene di (arylamino) methane made by reacting 2 mols. of aniline with 1 of formaldehyde, alternatively, aniline may be substituted by α- or #- naphthylamine, and may have neutral or basic substituents, and other aldehydes, e.g. acetaldehyde may replace formaldehyde. The diarylamine may be phenyl-#- naphthylamine, diphenyl-para-phenylene diamine, N-phenyl-N-tolylamines, #-naptha-phenothiazine, and may have neutral or basic substituents. In an example, after reacting methylene di (arylamino) methane with phenyl # naphthylamine, hydrochloric acid was added. The reaction product was made alkaline with sodium hydroxide and aniline liberated and removed by steam distillation. The presence of such age-resistors reduces the quantity of mercaptothiazole accelerator needed.

Patent GB-127366-A (GB)
Title: Improvements in or relating to Telephonic Systems.
Inventor: GRAHAM EDWARD ALBERT
IPC: H04M9/00
Filed: 1918-04-25
Abstract: 127,366. Graham, E. A., and Rickets, W. J. April 25, 1918. Direct-call systems; telephonic relays; telephones; condenser telephones.-An ionized-gas or electronic amplifier is associated with a telephone transmitter so that the impulses set up by the action of sound waves on the transmitter will be increased in strength by the amplifier. An electro-magnet may be connected to the transmitter and amplifier in such a way that low-frequency oscillations are set up when the circuit of the magnet is closed, these oscillations being used to give a call in the receiver at a distant station. In a modification, the oscillations energize a relay at the distant station, the relay closing a circuit through the filament of the amplifier, the glowing of the filament serving as a call. The transmitter may be a microphone, a condenser telephone, or a magnetic instrument. In the arrangement shown in Fig. 1 for two stations, current is supplied by a dynamo 16 through impedances to the leads 1, 2, across which loudspeaking telephones 4 and condensers 4a are bridged. When the switch 6 is moved in either direction, current flows through an inductance 5, contact 6<a>, non-inductive resistance 9 (which may be of iron, surrounded by hydrogen) and the filament 7<a> of the amplifier, thus energizing the amplifier so that current also flows from the lead 1 through the sheath or plate 7<b>, filament 7<a>, to the lead 2. One plate 10<b> of the condenser telephone 10 is connected to the contact 6<a> and the other 10<c> to the grid 7<c>, so that when the capacity of the telephone is varied by sound waves, corresponding variations are produced in the potential of the grid, causing amplified fluctuations in the plate circuit which includes the leads 1, 2 and the receiver at the distant station. When the switch 6 at station A is moved in a counterclockwise direction, so as to close contact 6<d> as well as contact 6<a>, current flows through a magnet 14 having an armature 13 attached to one plate of the condenser telephone. The magnet, transmitter, and amplifier co-operate to produce low-frequency oscillations, which produce a calling note in the receivers 4 at both stations, or cause the glowing of the filament at the distant station as previously described. Modified arrangements are described in which the two stations are connected by three or four wires. The condenser telephone may be replaced by a granular microphone 10<e>, Fig. 5, in which the rear electrode is connected to a reed 10f, vibrated by the magnet 14, the connexions to the amplifier being similar to those shown in Fig. 1. The transmitter may also be a magnetic instrument as shown in Fig. 6, the vibrations of the diaphragm by sound waves producing currents in the winding 10g which is connected to the grid circuit. For producing calling currents, the circuit of the auxiliary magnet 14, 15 is closed, movements of the diaphragm caused by this magnet setting up currents in the winding 10g in the grid circuit.
