Title: Pressed articles, particularly airscrew blades, of laminated wood and method of manufacturing the same
IPC: B27D1/08
Filed: 1937-03-31
Abstract: 493,145. Screw propellers ; aircraft spars. JABLONSKY, B. March 31, 1937, No. 9219. [Classes 4 and 114] The blades of an air-screw or spars and similar hollow structural parts of aircraft are formed of two shell sections of wood laminµ joined together with a moisture - resisting adhesive, each shell section forming in the case of a blade substantially one face of the blade and being made by assembling very thin wood laminµ between shaped dies, which dies may be heated as well as pressed together. The wood laminµ is preferably less than one millimeter in thickness and the laminµ may be assembled so that parts which take higher stresses are more highly compressed. The laminµ 9 are treated with a resin and pressed between the dies 7, 8 which have tubes 10 for conveying a heating medium. After pressing, the parts may be clamped together whilst the shell member is setting, and finally the free edges 11 are cut away. If desired, the shelllike members 2, 3 may be strengthened by inner longitudinal ribs 22 and the parts are subsequently united by glueing at the leading and trailing edges 6. For the purpose of securing the blade root within a cylindrical socket, it may have an inner stiffening tube 15 and an outer hardwood sleeve 17 to which a metal sleeve 16 is attached. Alternatively, the hardwood sleeve and metal sleeve are both placed inside and outer clamping sleeves are employed. The shell members 2, 3 may be enclosed in a metal sheeting 23, 24, the edges of which are joined by welding or by interlocking the edges 25. The leading edge may be formed by a separate member 30 dovetailed as at 34 into the outer shells, and such member may be formed with a rubber tip 37 or be wholly of rubber. The resistance to bending stresses may be increased by loading the blade tip either by adding weight or using material of high density. The wood laminµ mav be interleaved with laminµ of other suitable pliable material such as fabric or metal gauze.

Abstract: 1421306 Automatic gain control LICENTIA PATENT-VERWALTUNGS GmbH 1 March 1974 [1 March 1973] 9397/74 Heading H3Q An arrangement for the separate and simultaneous amplification of at least two high frequency voltages comprises a plurality of amplifier chains VZ, control voltage producing means VS, ES dependent on the output voltage of one amplifier and controlling all the amplifier trains and a switching means US for selectively feeding to an input of each amplifier train the associated high frequency or a control voltage. The arrangement is intended for use in a multiwave direction finder in which signals all of the same frequency are picked up on aerials A 1 - A y . The circuit ES selects from the signal outputs of the amplifiers the signal of greatest amplitude and the switch system US injects this into the amplifiers in alternation with the input signals. A number of phase-shifters PH 1 -PH y  derive a 90 degree phase-shifted signal from each signal channel, and this together with the signal is applied to a corresponding computing device, comprising sample and hold circuits in conjunction with analogue to digital converters AH 1 -AH y  and subsequent division circuits D 1 -D y  which divide the pair of signals of the initially fed-in high frequency voltages with the corresponding control signals, thereby obtaining outputs independent of the gain and phase shift in each channel.

Abstract: 351,486. Burglar and like alarms. BRIOT, P. J., 31, Avenue de Neuilly, Neuilly-sur-Seine, France. March 26, 1930, No. 9637. Convention date, March 26, 1929. Addition to 339,702, [Class 118 (i), Indicators &c.]. [Class 118 (i).] A device for signalling the approach of a body towards a given object operating by variation of electric capacity caused by such approach comprises. in accordance with the parent invention, a single oscillating circuit formed of self inductances o<1>, o<2> and p and of two capacities f<1>, g<1> in series, the grid b of a triode valve being connected direct to the midpoint of these condensers and to the filament a through a high resistance grid leak q of the order of 10-100 megohms. The capacity of the condenser g<1> increases with the approach of a body and the capacity of the condenser f<1> may be adjusted so that (a) the reaction applied to the grid is normally such that the device functions as an oscillator, the potential of the grid thus building up negatively so as to reduce the anode current substantially, (b) on the approach of a person towards the object to be protected the reaction alters so that the device ceases to oscillate and the grid potential returns to zero thus increasing the anode current and operating some form of signalling or alarm device or relay. The inductance o<1>, o<2> comprises two windings wound on a common former in the same direction and inserted in series in the filament circuit and the inductance p connects the inductance o<2> to the condenser f<1>. The effect of the inductances o<1>, o<2> is to raise the potential of the filament above that of the L.T. supply, when the device is oscillating, without producing any effect in the filament circuit itself. The condenser g<1> is formed by the object m to be protected and earth or an element n having a high capacity to earth. The H.T. and L.T. supply may be taken from town mains and are connected to earth through a low resistance. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement in which the condenser g<1> is replaced by a sectorial condenser a, A, a movable arm a of which is caused to move over the part A by the effect of variations of current produced in a sensitive device by the approaching body as a movable system, such as a galvanometer to which the arm a is connected. Moreover, the movement of the movable system which may carry an armature, inductance coil, electrode, obturator or the like may vary any element, e.g. inductance, capacity, &c., in which variation may be effected by the relative displacement of two parts, this variation being capable of altering an electric current in a sensitive apparatus such as oscillating, photo-electric and like apparatus. This subject-matter does not appear in the Specification as accepted.

Title: Heat-exchange tubing
IPC: B21C37/20
Filed: 1972-03-02
Abstract: 1390781 Heat-exchange tube NORANDA METAL INDUSTRIES Inc 2 March 1972 9683/72 Heading B3A A method of forming longitudinal heatexchange tubing 10 comprises providing a round metal tube blank 24, Fig. 4, having a peripheral wall 12 with inner fins 14, and reducing the interior space of the blank by partially flattening the blank to produce an oblong cross-section with two opposite parallel wall sections spaced apart to allow the fins on one wall section to extend with their tips 16, Fig. 2, at least level with the fin tips on the opposite wall section. The blank may be formed by brazing or otherwise joining inserted fins to the inner wall of the blank or displacing metal from the blank wall by swaging on a mandrel to form integral fins which may extend parallel or helically to the tube axis. The blank is then partially flattened to form the tubing 10 by passing through rotary rolls (30) (32), Fig. 12 (not shown), or by drawing the blank through a die (36), Fig. 13 (not shown). The number of fins provided and their height, as well as the peripheral extent of the wall, may vary within a range and tubes may be formed with overlapping fins, Figs. 6, 9, 21 (not shown), and fins which touch the opposite wall section, Fig. 11 (not shown). The tubing may be provided with both outer (108) and inner fins, Figs. 21, 22 (not shown), which may extent longitudinally or helically to the tube axis using suitable forming rolls. Moreover, a brazing strip (112), Fig. 23 (not shown), may be interposed between the fins (14e) and the blank flattened and then furnace heated to melt the strip and bond the fins at their intersections. This provides a tube strengthened to resist opening under internal fluid pressure. Also, the tubes may be strengthened by bending. This is done by curving or twisting the tubes either longitudinally, Fig. 18 (not shown), transversely, Fig. 19 (not shown), or both longitudinally and transversely, Fig. 20 (not shown).
