Title: Improvements in or relating to key-controlled punching machines for punching perforated records
Filed: 1929-07-19
Abstract: 315,882. British Tabulating Machine Co., Ltd., (Assignees of Lorant, R.). July 20, 1928, [Convention date]. Selective punching-machines. - In a machine for punching statistical cards A, columns 1 to 35 are punched in the usual manner, and means is provided for punching simultaneously in columns 36 to 45 the complement of the amount punched in columns 26 to 35. The data in columns 1 to 25 is selected on depression of keys 0 to 9 through circuit source 45, solenoid S<1>, and contact 43. The solenoids actuate Bowden wires attached to appropriate punch selecting bell-cranks 19. When column 26 of the card is under the punch selector row 19 column 36 is under a row of additional selector bell-cranks 18, for the complementary data, coupled to solenoids S". A switch 46 on the selector bar carriage is at this time closed by an adjustable fixed abutment 40. Depression of a key now completes the circuit above and, in addition, a circuit through source 45, contact 42, solenoid S" and switch 46. The solenoids controlling complementary numbers are wired to the keys as shown in Fig. 6. In a modification, a mechanically actuated machine has an extra set of selector bell-cranks which are cross-connected to the usual bell-cranks.

Abstract: 170,674. Munro, E. M. July 27, 1920. Vehicle fittings and attachments; overhead travellers ; trollies for runways.-Comprises means for loading and unloading motor vehicles. The vehicle is fitted with a framework mounted on the usual platform, a rotatable shaft carried by the framework, a winch mounted on and slidable along the shaft, and means for driving the winch from a motor on a vehicle. Fig. 1 shows one construction in which the framework comprises four corner posts 2 carrying two longitudinal rails 3 and two lateral rails 4. A rotary shaft 5, of circular or polygonal section, is carried by each longitudinal rail, and the shafts are driven in unison from shafts 7 carried by two of the posts and geared to a common cross-shaft 9 driven by worm gearing from a motor, which may be the propelling motor of the vehicle. A winch is mounted slidably on each shaft 5, and can be driven from the shaft at any point. Fig. 6 shows a modified construction in which the winches are fixed or mounted slidably on a shaft 5<a>, and the loads are suspended from travelling carriages running on the longitudinal rails 3 and arranged for single-cable hoisting and traversing. By fixing the carriage to the rails by means of a hand-operated cam (not shown), the pulley 52 is manipulated to raise and lower the load. In this construction, the rails 3 are carried on pivoted brackets at the tops of the corner posts, so that they can be swung out over the sides of the vehicle by means of worm gear 58 operated through bevel reversing gear 64 from the transmission shaft 9 that drives the winches. The pivoted brackets are arranged to permit one travelling carriage to project beyond the rear of the vehicle, as illustrated.

Title: Improvements in or relating to non-reciprocal high-frequency transmission systems
IPC: H01P1/32
Filed: 1956-07-19
Abstract: 800,892. Non-reciprocal filters and phaseshifters. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 19, 1956 [July 22, 1955], No. 22410/56. Class 40 (8). A non-reciprocal device for a two-conductor transmission line comprises one or more bodies of dielectric material and one or more bodies of high-frequency magnetic material arranged to extend side-by-side between the conductors in the direction of the electric field, the magnetic bodies being polarized in this direction. As shown in Fig. 1, two strips of ferrite 4a, 4b are arranged on either side of a strip 3 of dielectric material. The ferrite strips are oppositely polarized by a magnet 6 the inner conductor 2 of the transmission line being used to complete the magnetic circuit. In a modification (Fig. 2) two strips of dielectric material 3a, 3b and two strips of ferrite 4a, 4b are arranged on opposite sides of the inner conductor 2. A polarizing field is provided by the magnet NS. When energy is propagated along the transmission line a displacement current flows between the inner and outer conductors through the dielectric strips. This displacement current produces longitudinal components of magnetic field which are in quadrature with the tangential magnetic components of the wave energy. Thus a rotational field exists within the ferrite strips, the axis of rotation of which extends in a radial direction and the sense of rotation of which depends upon the direction of propagation. Under these conditions the effective permeability of the magnetic strips is different for waves propagated in opposite directions. If the polarizing field is adjusted to the value at which ferromagnetic resonance occurs, waves propagated in one direction are highly attenuated and waves propagated in the opposite direction are unaffected. If the polarizing field has a different value, waves propagated in opposite directions encounter different effective permeabilities and suffer different delays. The device may thus operate either as a non- reciprocal filter or a non-reciprocal phaseshifter.

[Also in Division A2] A prefabricated sheet metal fireplace construction comprises a solid-fuel burning firebox, having a draught opening 23 in the rear portion 22, and a smoke chamber 28 surmounting the opening 23 and connected at its upper end to a flue pipe 32 provided with a secondary sleeve 36 forming a conduit 37, Figs. 2 and 3. The fire-box front portion 20 has secondary walls 41, 42, 43 and 44 forming intercommunicating air passageways around the fire-box; spaced outwardly from these walls are further walls 52, 53, 54 and 55, the space between being filled with glass fibre blanketting 56. A baffle plate 101 is provided spaced from the fire-box rear wall forming an air passageway 102. The draught opening 23 is adjustable by means of a slidable damper plate 83 spaced from the fire-box top wall forming an air passageway. An outer casing 64 comprising side walls 61 and front and rear walls 62, 63 surrounds the fire-box rear portion 22 and the smoke chamber 28, the base being open to the exterior and the top connected to a sleeve 78 surrounding the upper portion of the flue pipe and sleeve 36. An access door 110 is provided in the rear wall 24 of the smoke chamber 28, and a removable panel in the wall 63 of the casing 64. A perforated flue cap 120 fitted to the top of the sleeve 78 directs some air into the flue opening 122 the remainder escaping through perforations 123. In operation, waste gases rise through the opening 23 into the smoke chamber 28 and the flue pipe 32, which they leave via the flue opening 122. Smoke passing the damper plate 83 causes a partial vacuum in the associated passageway and heated air is drawn from the front portion of the fire-box. Cool air enters the casing 64 at the base and circulates in the passageways about the fire-box, the smoke chamber and the flue pipe. The parts of the construction may be made of aluminium coated steel.

Abstract: 994,462. Transistor oscillator circuits. WESTERN ELECTRIC CO. Inc. June 22, 1961 [June 29, 1960], No. 22631/61. Heading H3T. In an inverter circuit for generating a rectangular output waveform and comprising two transistors which are rendered alternately conducting to supply current in alternately opposite directions through the primary winding of a transformer, the secondary winding of the transformer being arranged in series with a load and a direct-current feedback circuit comprising the series connection of the oppositely poled emitter-base circuits of the two transistors, each said emitter-base circuit is by-passed for currents flowing through the other by a rectifier diode connected in parallel therewith. In the circuit shown when conduction commences in one transistor e.g. 101, current feedback through the secondary winding of preferably-saturable transformer 103 and the load connected between terminals 107, 108 is in such a direction as to render diode 110 conducting and to cut diode 109 off so that current flows through the emitter-base diode of transistor 101 to maintain conduction therein. This continues until saturation takes place whereupon the feedback reverses in sign and transistor 102 becomes conductive. The reversal of the feedback now causes diode 109 to conduct and diode 110 to be cut off, this process continuing so that an alternating current is supplied to the load. In the circuit shown the transistors are connected in the commonemitter configuration; in modified circuits common-base, Fig. 2 (not shown) and commoncollector, Fig. 3 (not shown), configurations are used.
