Title: Electronic musical instruments
IPC: G10H5/02
Filed: 1949-12-20
Abstract: 673,027. Electrophonic musical instruments. MARTIN, C. Dec. 20, 1949. [Dec. 28, 1948] No. 32662/49. Class 88 (ii). An electrophonic musical instrument comprises a keyboard controlling two independent oscillators, adjustable in semitones, one by means of a series of condensers and the other by means of a series of resistances orinductances. When two or more keys are pressed together, one oscillator emits the highest note of the chord and the other emits the lowest note. As shown, multivibrators.A, B are tuned by means of resistances 8 and condensers 25. Each key 43 controls two switches 16, 34 and, if pressed alone, tunes both multivibrators to the same note. The two oscillators are connected to a common amplifier 48 and loudspeaker 49 through independent volume controls 45, 47 and tone controls 44, 46, Separate amplifiers and loudspeakers may be provided for each channel. Alternatively, an amplifier, loudspeaker, tone control and volume control may be common to both oscillators. The fundamental frequencies of the two oscillators may be offset to produce a beating effect..

Title: Adjustable beds
IPC: A61G7/018
Filed: 1975-08-05
Abstract: 1507319 Adjustable hospital beds HILLROM CO Inc 5 Aug 1975 [9 Aug 1974] 32718/75 Heading A4J [Also in Division G3] The mattress support of a hospital bed is adjustable in height and has knee and head portions which are raised and lowered by respective motors 11, 12 and 13 under the control of electronic logic circuitry which, in conjunction with the position of manually operated switches on control panels 19, 20, 21, determines the particular movement of the mattress support. The circuitry includes two position indicating switches which ensures that when the head portion is raised, the knee portion is raised by 15 degrees to the horizontal and that when the head portion is lowered, the knee portion is lowered only when the head portion is at or below 30 degrees. When the mattress is to be moved to one of the two Trendelenburg positions, the mattress support is first elevated to its highest point and that end of the support which is to be uppermost in the Trendelenburg position is engaged by a hook. Engagement of the hook is indicated to the logic circuitry which then causes reversal of the elevation motor and lowering of the other end of the support. A master control panel 17 is positioned at the foot end of the bed and includes three lockout switches which can be opened to immobilize the three motors and the switch for the Trendelenburg positions. The master control also includes a bed flat switch which is coupled to the logic circuitry to cause operation of all three motors to move the bed portions to a horizontal position when the bed flat switch is closed. Bed position indicators 16 in the form of switches indicate to the logic circuitry the limits of adjustment of the height of the mattress support and inclination of the knee and head portions.

Title: Improvements in or relating to projectiles for use in catching whales and other mammals
IPC: F42B30/14
Filed: 1919-12-31
Abstract: 165,478. Henkes, A. Dec. 31, 1919. Projectiles.-A whaling projectile comprises means for liberating a non-inflammable gas in a non-explosive manner from a container to inflate a whale or other mammal, and a plug member adapted to be separated from the container and plug the entry hole. In one form, as shown in Fig. 1, a thin metal sleeve 9 is adapted to be stripped off the projectile on entering the whale, thereby allowing a gas, such as carbon dioxide, to escape through holes 12 from a chamber 11, enclosed by a head 1, a body part 2 and a bottom part 3 of a projectile, and releasing spring-blades 6, secured to a plugging-member 4 and normally held in recesses 8. The spring blades then spread out and grip the whale body, thereby stopping the member 4, which plugs the entry hole and stops the body of the projectile after stretching a spirally wound connecting-rod 5. A pin 14 may be secured to a spring-controlled plunger, having a pin adapted to enter the chamber 11 and start the liberation or production of gas. In a second form, as shown in Fig. 3, the projectile is stopped in the whale by the explosion of a charge in the head 1, which may be started by means of claws 21 being turned inwardly against springs 23. This motion may also be utilized for piercing a wall of a chamber containing compressed gas, or for starting a chemical action to produce gas, which escapes through openings 22. The plugging-member 4 is detachably connected with the body 3 by means of barbed spring-blades 15, secured in undercut recesses 16 of the body, and is provided with pivoted-wings 19, which are forced outwards by springs 20, on firing the projectile, and so prevent the member 4 from entering the whale. In a third form, the plugging-member 4 is provided with a plurality of projections. In a fourth form, similar projections are provided on pivoted wings which swing outwards on leaving the gun, and a rubber sleeve is stripped off the bottom piece to assist in closing the entry hole. In a fifth form, as shown in Fig. 7, the body 3, the bottom-piece 2, and the plugging-member 4 are provided with grooves 31. A disc 32, having screw blades 33, has projections which engage the grooves 31 and, on the projection penetrating the whale, slides along the grooves and detaches the member 4. In a sixth form, the projectile is composed of a head in the form of a shell, an intermediate piece, having spring-loaded folding barbs, a steel body filled with liquid carbon dioxide, and a plugging- member, having spring-loaded L-shaped folding barbs, which swing out to an intermediate position on leaving the gun and to their full extent on striking the whale.

Title: Improvements in or relating to electric amplifier arrangements
IPC: H03H7/48
Filed: 1955-11-17
Abstract: 803,349. R.F. couplings; frequency selective valve amplifiers. GENERAL ELECTRIC CO., Ltd., and GRIFFITH, G. W. S. Nov. 12, 1956 [Nov. 17, 1955], No. 32962/55. Classes 40 (6) and 40 (7). An amplifier arrangement is designed so that if a proportion of its output signal is delayed and reflected back due to mis-match energy is not again reflected and returned to the output. As described, the arrangement feeds an aerial 22 with energy originally derived from amplifier 20. The input energy is fed over line 19 to a point 9 on coaxial line hybrid ring 3 which has a total length of 1¢ # and has coupling points 7, 9, 10 and 8 at #/4 intervals round one half of it. Equiphase energy from hybrid ring 3 is fed from points 10 and 7 over lines 15 and 17 to amplifiers 1 and 2 and these feed points 11 and 14 on a second hybrid ring 4 over lines 16 and 18. The signals received at points 11 and 14 add at output connection 13 on the second ring and are led over line 21 to the aerial. According to the invention it is arranged that the signals fed to amplifiers 1 and 2 differ in phase (but are not in quadrature) and that the paths from them to the hybrid 4 differ in length (but not by an odd number of quarter wavelengths). The two amplifiers are detuned so that one has an inductive and the other a capacitive impedance and the line lengths and impedances are so chosen that the effective path lengths between points 10 and 11 and between 7 and 14 are equal. In the embodiment described line 15 exceeds line 17 in length by #/5 and line 18 is longer than line 16 by #/8. Where a reflected signal is returned down line 21 it is divided equally between lines 16 and 18. The lengths of these lines are chosen so that, with the different reactive terminations presented by the amplifiers 1 . and 2, energy reflected at the amplifiers is returned to points 11 and 14 on ring 4 in anti-phase and has no effect at point 13. It is, however, absorbed in resistive load 24. The coaxial line hybrid rings 3 and 4 may be replaced by waveguide loops or may be waveguide hybrid T junctions. Valve amplifiers.-Fig. 2 shows a possible form of one of the amplifiers 1, 2. This includes three co-axial conducting cylinders 27, 28 and 29 with a valve 30 mounted as shown in relation to the cylinders. The input is over line 15 which is loop-coupled to resonant cavity 37 bounded by cylinders 27 and 28 and tuned by annular piston 38. This cavity is associated with the valve grid circuit. A second cavity 39 bounded by the cylinders 28 and 29 is tuned by piston 40 and is coupled to output line 16 by means of probe 41. The piston 40 can be adjusted to give the detuning effect necessary for the operation of the arrangement described with reference to Fig. 1. Specification 735,927 is referred to.

A transformer for supplying heater current for two emitters of an X-ray tube comprises an iron core 1 on separate limbs of which are wound a primary winding 2 and a secondary winding 4, the secondary winding consisting at least in part of soft magnetic material and forming the magnetic core for two toroidal windings 7, 8 surrounding the secondary winding 4. The iron core 1 may have an air gap therein and may be formed of a ferrite. The magnetic part of the winding 4 may be formed of iron wire, band or sheet material and this part may be in series or parallel with the remainder which may be of copper. Thus windings 2, 4 form a transformer to supply one emitter of the X-ray tube and windings 7, 8 form another transformer to supply the second emitter of the tube.

Title: Improved automatic electromagnetic interrupter for oscillating motions of bells and the like
IPC: H01H51/34
Filed: 1935-12-03
Abstract: 455,680. Electromagnetic interrupters. SLEGERS, A. J. H. G., Tellin, Belgium. Dec. 3, 1935, No. 33470. [Class 38 (v)] An electromagnetic interrupter for controlling the supply of current to electromagnetically - oscillated bells has a sector bolted to a forked lever mounted freely on a shaft the sector rotating in a casing 8 which is rigidly attached another lever, said levers being provided with contacts which are adapted to be brought into engagement during the braking of the sector, the contact being interrupted by a spring as soon as the braking effect on the sector ceases. As shown in Figs. 1 and 2, the shaft a which is connected to the bell carries on a squared extension an arm d carrying on a laterallyextending insulating arm contacts c<3>, c<4>. Freely mounted on the shaft a is a forked lever v on one arm of which is a laterally-extending insulating arm 12 bearing co-operating contacts c. Between the two contact bearing arms is a spring r<3>, normally holding them apart. Attached to the lover v is a sector s adapted during the movement of the bell to move between spring-pressed braking members p, p<1>. Thus when the bell is oscillating in the direction of the arrow 1 the contacts are maintained out of engagement during the whole stroke but on reverse movement in the direction of the arrow 2, immediately the braking action on the sector s commences the contacts engage and move together until the braking action ceases and the spring r<3> again forces them apart. Thus the circuit to the operating electromagnet is completed during a portion of this stroke so that the bell is maintained in oscillation. The casing containing the interrupter may be filled with oil above the contacts to prevent sparking therebetween. Leads to the interrupter contacts pass through the hollow end 2 of the shaft to terminals on insulating members 15, these terminals being then connected directly to the interrupter contacts.
