Abstract: 220,228. Fiacchetti, M., Sola, E., and Compagnia Italiana dei Segnali. Jan. 15, 1924. Lighting and heating systems.-In a remotecontrolled' switching arrangement for lamps or other devices, a spare lamp &c. is automatically switched in, when a regular lamp fails, by the unbalancing of a differentially wound electromagnet, which further operates audible and visible signals. In an arrangement for four regular lamps and four spare lamps, Fig. 1, the control station, shown on the left of the Figure, is provided with four differentially wound electromagnets E', E<2>, one winding of each being in the circuit of a corresponding distant lamp A and the other winding being in a local lamp circuit. Failure of a lamp A results in closure of a corresponding pair of contacts C, which throw in a spare lamp and also give visible and audible warning by means of magnets I. Commutators M allow the lamps A and B to be changed over when required.

Patent GB-642377-A (GB)
Title: Method of manufacture of shaped articles from organic bodies or parts thereof
IPC: D06M15/15
Filed: 1947-01-15
Abstract: Artificial fibres, films, or sheets, or finishing-compositions for textiles are prepared from a mass resulting from the mechanical disintegration of animal tissues or organs other than hide and epithelium tissues under conditions such that putrefaction or coagulation will not occur.  Disintegration can be effected by grinding, expansive bursting, or by the action of supersonic waves. The natural water-content can be supplemented by the addition of 0.1-10 times the amount of water present. Agents for facilitating dispersion such as alkaline substances, sulphonated oils, urea, glycerine, phenols, lactates, or soaps, solvents such as di- or tri-hydric alcohols or phenols, decolouring and deodorizing agents such as peroxides, chlorine, or scents, softeners such as di-or tri-hydric alcohols, oils, fats, isobutylphthalate, tricresyl phosphate, camphor, or hygroscopic salts such as calcium or magnesium chloride, and coagulating-agents such as ammonium sulphate, chromium, iron, or aluminium compounds, acids, formaldehyde, paraformaldehyde, hexamethylenetetramine, quinine, or tannic acid can be included. Preferably the temperature is maintained below 50 DEG  C. unless a dispersion in a polyhydric alcohol such as glycerine is required. The paste so obtained can be heated with solvents or swelling agents for colloidal substances, such as polyhydric alcohols, proteolytic enzymes, or oxidizing-agents such as hydrogen peroxide.  The paste is then forced through nozzles of selected shape into a coagulating-bath, or is dewatered, rolled, pressed, or moulded, and coagulated by heat or immersion in a chemical bath.  Fillers such as wood flour, dyes, foam, gas-producing agents, or photo-sensitive materials may be incorporated.  The Specification as open to inspection under Sect. 91 describes also the use as raw materials of vegetable products, skin, and detanned leather.  This subjec-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to planetary gear trains and hoists incorporating such gears

Abstract: 1,131,962. Hoists. INGERSOLL-RAND CO. 12 Jan., 1967 [12 Jan., 1966], No. 1696/67. Heading B8B. [Also in Division F2] To promote even load division between, and correct alignment of, the planet pinions of a planetary reduction gear of an overhead hoist, pairs of planet pinions 27, 28 being splined on to shafts 21 rotatably mounted in a carrier 20, the splines of each pinion and/or shaft are crowned to allow each pinion to rock on its shaft, and the carrier 20 floats radially. The hoist (Fig. 1, not shown) comprises a reversible electric motor (5), a reduction gear and brake unit in a casing portion (3), and, in a casing portion (4), a sprocket 9 over which passes a chain (7) carrying a lifting hook (8). In the reduction gear, the planets 27 mesh a sun gear 17 integral with a shaft 15 driven by the motor shaft 12, and an internally toothed reaction annulus 35, while the planets 28 mesh an internally toothed ring gear 32 integral with a hollow shaft 10 to which the sprocket 9 is splined. A one-way sprag clutch 41 connects the shaft 10 to a sleeve 40 to which are splined brake discs 43. Discs 44 interleaved therewith are held against rotation by engagement with fixed longitudinal bars (37) (Fig. 3, not shown) which also engage cutouts (36) (Fig. 4, not shown) in the reaction annulus 35 to allow the latter limited rotational freedom. Ramps 50, Fig. 5, on one end of annulus 35 engage ramps 51 of casing 3. When a stationary load is supported by the hoist, the resultant torque on the annulus 35 rotates it in a direction causing the ramps 50, 51 to move annulus 35 axially rightwards, Fig. 2, to act via an extension 48, a sleeve 49, and a pressure-plate 46, to apply the brake. When the motor is run to lower the load, the torque on annulus 35 results in axial motion to release the brake, the load torque overrunning the motor torque causing the brake to be alternately applied and released. The pressure-plate 46 and a disc 52 are splined to the extension 48 to allow transmission, from the shaft 10 via the sprag clutch 41, of a load torque tending to apply the brake, to prevent coasting or slip of the load after the motor has been de-energized. When the load is raised, the shaft 10 rotates in the free-wheel direction of sprag clutch 41 so that the brake does not impede lifting.

[Class 40 (iii)] Frame and line synchronizing signals, applied to a thermionic valve-1, control current passing through an inductance 4 which is so connected to a unilaterally conducting device 7 that the current through the latter ceases on the application of a framing pulse. The derived frame pulses are obtained from the output of the diode 7. The inductance is in series with a resistance 5, and the time constant of the combination is long compared with duration of the frame signal. The anode of the diode is connected to the end 6 of the inductance remote from the anode of the valve 1 and such a positive potential is applied to the cathode of the diode that current flows through it until the frame signals are received. The line synchronizing signals may be derived from the screening grid of the valve 1. According to modifications : a second anode in the diode is connected to the end of the inductance adjacent the anode of the valve 1 to provide a short circuit across the inductance on the conclusion of the framing signal and thus damp possible oscillation in the coil, Fig. 4, Provisional Specification 1728/37 (not shown) ; the inductance and the diode constitute a shunt across the valve, and the resistance 5 is connected between the source of voltage and the anode of the valve or a tapping on the inductance, Fig. 1, Provisional Specification 7971/37 (not shown) ; two anodes in the diode are connected to opposite ends of the inductance, Fig. 2, Provisional Specification 7971/37 (not shown).

A hydraulic jack comprises a fixed piston 2 and a movable cylinder 1, the latter housing a hollow spool valve T which is slidable on a guide rod 5 under the control of a manual operating lever 4. In the neutral position shown, jack chambers 17, 19 communicate with exhaust port 24 via passages &c. 16, 14, 20 and 22 and 18, 15, 21 and 23 respectively. When valve T is moved to the right, grooves 15, 21 are cut off from each other and a shoulder 25 on rod 5 unseats a valve 12 which is one of a pair of such valves 11, 12 located in a chamber 8 in valve T, thereby admitting fluid from an inlet 10 to chamber 19 via chamber 8 and passages 7, 18. Consequent rightward movement of cylinder 1 reseats valve 12 and brings grooves 15, 21 back into communication with each other. A similar sequence occurs when valve T is moved to the left. A shoulder defined by diameters d2, d3 is provided at each end of rod 5 and the spaces 27, 28 there around communicate with passages 6, 7 via longitudinal passages 29, 30. These shoulders provide "feel" for the operator. A force providing "feel" is also generated on valves 11, 12.
