Abstract: 830,172. Linear motors and collecting gear therefor. BRITISH THOMSON-HOUSTON CO. Ltd. July 19, 1957 [July 25, 1956], No. 23024/56. Class 35. To provide different motor operating speeds an armature winding is constituted by a number of winding sections A, B, C, each having its ends brought out to terminal contacts CS carried by the armature 1 and selectively interconnected by means which provide different interconnections between the sections; this is embodied in a linear motor comprising at least one magnetic armature movable lengthwise of an axis extending therethrough, a magnetic field structure 2 defining at least a pair of pole faces at axially spaced positions facing the armature, the winding carried by the armature and having at least some of its turns passing between the pole faces and the armature, and for applying current to these turns connecting means permissive of armature axial movement whereby interaction between the field structure flux and the armature current produces a force having a component urging the armature along its axis. As shown in Fig. 3 the interconnecting means comprises a contact strip having a plurality of contact elements C so shaped and positioned that when applied against the contact segment assembly shown in Fig. 2 all the coils A, B, C, &c., will be interconnected in series, the contact strip moving with the contact segment assembly during operation and the latter being engaged by stationary brushes BR; other shapes of contact element disclosed provide alternative series-parallel coil interconnections. The Specification states that the interconnecting means alternatively may comprise a rotatable drum or other such device. Specification 805,223 is referred to.

Title: Adhesive tapes
IPC: C09J7/22
Filed: 1955-08-12
Abstract: 822,884. Reinforced pressure-sensitive adhesive tape. SMITH, J. J. Aug. 12, 1955 [Aug. 13, 1954 (2)], No. 23342/55. Addition to 680,657. Class 140. An adhesive tape comprises a coating 16a, Fig. 2, of pressure-sensitive adhesive on one surface of a flexible backing 14a of yieldable normally non-tacky plastic in which is embedded reinforcing strands 18a extending substantially longitudinally therein and each capable of slight independent longitudinal movement to distribute tensile forces applied to the tape. The strands and backing may be so chosen that the tape is transparent or variously coloured. The strands may be embedded during moulding of the backing by pressing them into the backing, by assembling three layers of plastic, the middle one containing the strands, Fig. 3 (not shown), or by disposing the strands between two layers of plastic and applying heat and pressure, Figs. 4 and 5 (not shown). The backing may be of such material as rubber, polyethylene, polyfluoroethylene, superpolyamides, plasticised vinyl chloride polymers, acrylates and methacrylates. The preferred strands are of glass, e.g. of glass yarn, but synthetic filaments or natural threads, as exemplified, or wire may be used, and they may be given a preliminary coating, as with rubber, butadiene/styrene copolymer, butadiene/acrylonitrile interpolymers to improve bonding to the backing.

Patent GB-478826-A (GB)
Title: Improvements in electric oscillation systems
IPC: H03F1/13
Filed: 1936-08-25
Abstract: 478,826. Valve circuits for wireless reception; generating circuits. HAZELTINE CORPORATION. Aug. 25, 1936, No. 23345. Convention date, Sept. 28, 1935. [Class 40 (v)] A multi-frequency tuned system comprises a plurality of condensers and inductances adapted to be selectively connected into different groups to form a plurality of tuned systems having different resonant frequencies, one of these systems including a component tuned circuit having a natural resonant frequency in the vicinity of the resonant frequency of one of the tuned systems, additional means being provided for imparting to this component a decrement greater than that of any of the tuned systems, so that the responses of the tuned systems to the resonant frequency of the component is attenuated without substantially impairing the responses of the tuned systems at their respective resonant frequencies. Each system is tunable over a band of frequencies. The invention is applied to the multi-band superheterodyne receiver shown, having a radio-frequency selector and amplifier 31, the output of which is connected through a multi-band coupling system 34 to an oscillator modulator valve 35, provided with an oscillation system 37, the valve 35 being connected through an intermediate frequency amplifier 40, a detector and automatic amplification control source 41 and an audio-frequency amplifier 42 to a sound reproducer 43. The oscillation system 37 comprises three series-connected inductances 66 ... 68 across which is connected a tuning condenser 70. In shunt with each inductance is an adjustably fixed condenser 76 ... 78, and in series with the condenser 77 is a resistance 79, which serves to increase the impedance of the component tuned circuit 67, 77, 72, 73, 79 and thus its attenuation, without substantially increasing that of the composite circuit so that when the ganged switches 32, 60, 80, 81 are adjusted to their middle positions for reception in the middle frequency range, the tendency of the oscillation system to jump from the desired frequency to that of the component circuit is eliminated, this effect being increased by connecting the low potential terminates of the condensers 76 ... 78 directly to ground. When the receiver is adjusted to its low-frequency range, any tendency to jump from the frequency determined by the composite circuit to that of the component circuit 66, 76, 71 ... 73 is eliminated by making inductance 66 large and of a universal wound coil of relatively fine wire, whereas inductances 67, 68 are of single layer windings of larger wire, so that the former has a large attenuation, while that of the latter is small. Suitable values for the oscillation circuit elements are given in the Specification. Feedback from the valve 35 to the inductances 66 ... 68 is obtained from the common coil 90 and the condenser 73 serves as an additional back-coupling element and is effective to maintain the amplitude of the oscillations within desired limits over the tuning range of the system.

The connectors are urged by a spring towards the delivery opening 70 in the magazine. The loaded magazine is inserted when the handles are closed and the plunger is in advanced position. On separating the handles the plunger is retracted and with it the magazine a part of the inclined surface of the member 60 forming a closure for the delivery opening 70. The magazine is retained in retracted position by detent elements 94, 96. When the plunger has been fully retracted the magazine is manually advanced whereupon a connector blank drops,through the opening 70 into the path of the plunger 26. The handles are then brought together to advance the plunger thereby positioning the connector against the moulds 30, 32, 34. As the plunger advances the spring pin 58 reaches the slot 82 in the magazine and moves upwardly into engagement therewith. A ratchet mechanism prevents separation of the handles until after they have been closed sufficiently to crimp the connector. An insulation stripper 38 is provided.

Title: Improvements in and relating to steering aileron or elevator mechanism for aircraft or other craft
IPC: B64C13/02
Filed: 1930-08-05
Abstract: 356,418. Arrangement of springs. BRUCE, R. A. HILL, G. T. R., RATCLIFFE, J. W. and PETTERS, Ltd., Westland Works, Yeovil, Somerset. Aug. 5, 1930, No. 23478. [Class 108 (iii).] Spring mechanism employed for the relieving the pilot of air- or water-craft from loads occasioned in operating control surfaces such as occur when one engine of a two-engine machine stops, is provided with means for obtaining any desired degree of biasing force throughout the whole range of movement. The device is shown diagrammatically in Fig. 4, in which b is a rudder bar, a a main helical spring operating either in tension or compression, and m is a balancing spring operating in compression. The strength of springs a, m is so adjusted that the tension on a when moved as shown is balanced by the pressure of spring m on a bell-crank lever h linked by a rod to the end of the main spring ; similarly in the reverse position substantially no load is placed on the rudder bar by the springs. By increasing the compression of the balancing springs m, a destabilizing force is introduced on displacement of the control surface assisting the pilot to overcome the aerodynamic loads. By shortening or extending the spring a, the balance of the arrangement is upset and a biasing force introduced causing the control surface to be maintained over to one side or other of its neutral position. In an application to an aircraft rudder control, Fig. 2, the spring a is fixed to one end d of a tube c connected by levers and a link to the rudder bar ; the other end of spring a is fixed to a nut e screwed on a threaded tube f extending within tube c and mounted in a trunnion bearing upon a fixed part of the machine structure. The bell crank h is also mounted on this bearing and is connected at one arm to the end d of tube c and at the other arm to compression springs m which in the neutral position are in line with this arm. A handle g rotates the tube j to cause extension or compression of spring a by moving nut e axially, and a nut n enables the position of the abutment of springs m to be set. Specification 190,560, [Class 108 (iii), Springs &c.], is referred to.
