Title: Improvements in or relating to the production of assemblies of gelatin layers and tocolour photographic materials containing the same
Inventor: REAN AUBREY JOHN
IPC: G03C1/047
Filed: 1955-06-17
Abstract: 792,677. Gelatin layers for photographic procedure. ILFORD, Ltd. June 29, 1956 [June 17, 1955],.No. 17606/55. Class 98(2) Substances such as dyes are caused to be retained in one of a pair of adjacent gelatin layers as in multilayer procedure, by using gelatin of low isoelectric point such as that made by the line process for one of the layers and of high isoelectric point such as that made by the acid process for the other, and using a basic substance in the former layer or an acidic substance in the latter layer, or vice-versa. A test to facilitate selection of suitable gelatins, using acid and basic dyes, for the purpose is described and the results thereof are tabulated. The invention is further illustrated by reference to two examples of light sensitive material for the silver dye-bleach process which are, however, extended only sufficiently to show that (1) the magenta dye Polar Brilliant Red 10B is retained on processing better in gelatin of high isoelectric point than in low, when the 'adjacent layer is of low isoelectric point, and (2) the cyan dyes Direct Sky Blue GS and Solophenyl Blue Green BC are retained better similarly. The effect of aqueous processing only is compared similarly. The Provisional Specification indicates that use of the principle of the' invention in a reversed aspect is of value in making coloured images by the dyeimbibition process. Specifications 647,168 and 711,233 are referred to.

Title: Improvements in or relating to direct current electric ship propulsion or the like systems
IPC: H02P7/34
Filed: 1937-06-28
Abstract: 499,872. Control of D.C. motors transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., COATES, H. J., and JAKEMAN, R. G. June 28, 1937, No. 17950. [Class 38 (iii)] [Also in Group XXXV] In a ship-propulsion system in which a motor 1 receives power from a generator 4 driven by a prime-mover, and in which, when the motor operates as a generator, the regenerated power is absorbed by a direct or alternating-current auxiliary generator 8 coupled to the prime-mover, control means associated with the governor mechanism 22 of the primemover are effective to render the auxiliary generator operative to absorb power incapable of being absorbed by the system, and further means are provided for preventing effective operation of the control means during idling. The auxiliary generator 8 may normally supply auxiliary bus-bars 3, and is loaded by the closure of a contactor 10 energized by closure of contacts 21 operated by the governor 22 when the supply of fuel to the prime-mover falls to a predetermined value. The circuit of the contactor 10 may include contacts of relays 13 and 14 responding to the direction of armature current in relation to the voltage of the generator 4. Instead of relay means responsive to regenerated power, the loading of the auxiliary generator during idling may be prevented by interlocking the contactor 10 with the master controller. The auxiliary generator may comprise a direct-current field system arranged around a fly-wheel. Specification 197,753, [Class 38 (iv)], is referred to.

Abstract: 369,100. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B. ; 155, Hodge Road, Princeton, New Jersey, U.S.A.) June 22, 1931, No. 18023. Convention date, July 10, 1930. [Class 40 (v).] Frequency or phase modulation of a carrier wave is effected by passing the wave through a circuit whose L.C. value is half that necessary for resonance, and by applying the signal as variations of resistance either across the condenser, or in series with the inductance, of the tuned circuit. As shown in Fig. 1, a constant voltage of carrier frequency is applied at the terminals 8 of a circuit comprising an inductance 6 in series with a condenser 4 shunted by a variable modulating resistance 2. As the resistance 2 is varied the current through the circuit remains constant, but the phase varies. The circuit 4, 6 may be interposed in an amplifier chain, and the resistance 2 may be the plate-filament path of a valve which has its grid voltage varied by a microphone or other signal producer, Fig. 2 (not shown). The phasemodulated output may be taken by a coil coupled to the coil 6 and may be amplified and passed through a current-limiter before proceeding to the radiating aerial. In a modification shown in Fig. 3, a screen-grid carrier wave amplifier 10 giving a constant output current has in its plate circuit a condenser 4 shunted by a coil 6 in series with a microphone 30 or other variable resistance, the L.C. value of 4 and 6 being half that necessary for resonance with the carrier. Phase-modulated output is taken through a condenser 32 to an amplifier and limiter 34 and thence to the aerial.

Title: Magnetic shift register
IPC: G11C19/04
Filed: 1955-07-23
Abstract: 800,186. Pattern-movement stepping registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 23, 1955 [June 23, 1954], No. 18177/55. Class 106 (1). A magnetic core shifting register, using one core per bit, includes a transfer circuit between each adjacent pair of cores coupling two windings on one core with one winding on the preceding core. The two windings on the one core may be constituted by one centre-tapped winding. Each shift pulse, applied to windings 10, 11, 12, Fig. 2, sets each core to its 0 state, and any core that was in its 1 state, say core 13, induces a voltage in a coil 16 causing a condenser 18 to be charged via a diode 17. On the termination of the shift pulse condenser 18 discharges through the circuit comprising inductance 22, resistor 21, windings 20 and 19, ground and winding 16, diode 17 being blocked, and as a result the next core is set in its 1 state. The discharging current, since it passes through winding 16 on core 13, also tends to set the core 13 to its 0 state, but it is stated that if a 1 is being transferred to core 13 from a preceding core then the effect of this current is cancelled by the current, which flows in both coil 16 and 23, tending to set core 13 in its 1 state.

A screen is composed of brush tufts arranged in overlapping relationship at an acute angle to the screen surface. The invention is described as applied to a reciprocating screen used to remove powdered starch from sweetmeats which have been moulded in starch-powder moulds. At A, Fig. 1, trays containing the sweetmeats 7 in the starch moulds are fed to region B where they are inverted to discharge their contents and then passed to a conveyor 9 for refilling &c. at C, D, E. The discharged material falls on to the sloping screening-unit F, which is vibrated at its upper end by lever and crank mechanism 14 ... 19 and rests on a roller 13 at its lower end. The upper portion 20a of the screen is a flat sheet merging into a perforated trough-like portion which effects preliminary separation of the starch which falls on to a conveyer 20b for return to the refilling station C. The remainder of the material passes to the trough-shaped brush screen T above which oscillates a cleaning brush 21 carried by arms 22 driven by cranks. The screen T discharges the cleaned sweetmeats on to a shoot 38, and the starch passing through the screen is fed to the conveyer 20b by a further conveyer 37. The brush screen comprises sections composed of longitudinal frame members 27, Fig. 5, connected by arcuate cross members 29 to which longitudinal supports 31 are fixed. Arcuate brush holders 32, Figs. 5, 8 and 9, are arranged transversely across the screen and are of trapezoidal cross-section, the tufts 39 in the side b, d of one brush holder resting on and overlapping the sloping top a, b of the adjacent holder. The tufts may comprise fibre, bristle, hair or nylon elements and the gaps therebetween are narrower than the sweetmeats 6 to be cleaned. In an alternative construction the screen is formed of two longitudinal metal channel members to which the tuft holders are directly secured, Figs. 10, 11 (not shown).
