IPC: H02G15/06
Filed: 1973-03-23
Abstract: 1455414 Cable glands FAIRLESS ENG SUPPLIES CO Ltd 11 Jan 1974 [23 March 1973] 14114/73 Heading H2E A cable gland for an armoured cable having a core, a sheath and armouring wires between the core and sheath comprises a gland body 1 with a central bore 4 of such a diameter that only the core can pass through and an externally threaded boss 2, a locking nut 5 having a central bore 6 of a diameter to allow the sheathed cable to pass through and with an enlarged bore threaded to engage the boss 2 and an annular disc 7 with parallel sides enterable into the enlarged bore region to seat on the radial base surface and with a bore of a diameter to allow only the cable core and armouring wires to pass through. The gland body may be threaded to engage apparatus. Sealing rings (not shown) of synthetic rubber may be placed in a recess in the inner surface of the boss 2 to be forced against the cable when the body is engaged with the locking nut. The locking nut may also be formed with a boss having an external thread to be engaged by a further locking nut to clamp a sealing ring against the cable sheath. The gland is said to ensure electrical earth continuity between the armouring wires and the body of the gland sufficient to carry the current of one of the conductors of the cable.

Title: Improvements in the manufacture of ichthyol oil and ichthyol preparations and the like
IPC: A61K35/02
Filed: 1921-05-21
Abstract: Fossilized fish shale, sulphurized shale, and fossils containing sulphur are treated to obtain ichthyol oil and preparations by high-speed mechanical disintegration in presence of a liquid, preferably water, at a peripheral speed of over 1,000 metres per minute, preferably in a colloid mill as described in Specification 155,836, [Class 1 (i), Chemical processes &c.]. Protective colloids may be added, in which case the emulsions obtained are permanent and are suitable for therapeutic use.  The oil may be separated from the emulsion by heating to 60-70 DEG  C. with or without addition of an electrolyte or by centrifuging. The oil may then be purified by extraction with an organic solvent, filtration, and evaporation of the solvent.  In examples Seefeld oil shale, previously ground, is dispersed in water and the oil separated by each of the above-described methods.  The oil is further treated in a colloid mill with water and alkali caseinate to obtain a creamy emulsion.ALSO:Fossilized fish shale, sulphurized shale, and fossils containing sulphur, such as are found in Seefield and Tuscany, are treated to obtain ichthyol oil by high speed illegible mechanical disintegration in presence of a liquid, preferably water, at a peripheral speed of over 1,000 metres per minute, preferably in a colloid mill as described in Specification 155,836.

Title: Improvements in electro-magnetic clocks
IPC: G04C3/027
Filed: 1921-05-23
Abstract: 163,694. Bulle, M. P. Favre-. May 23, 1921. Electric clocks ; clock framework; clock movements.- An electromagnetic clock has a forked rocking member 14, Figs. 1 and 2, which drives the clock-work by means of a pawl 6 and is engaged by an arm 16 on the pendulum 3, the contact of the arm 16 with one of the prongs of the member 14 causing the excitation of the magnet coil that maintains the motion of the pendulum. The pivot 15 of the member 14 is arranged below its centre of gravity, a stop 17 being arranged to limit its movement. The ratchet-wheel 7 engaged by the pawl 6 has fixed to it a worm 8 engaging a worm-wheel 9 on the shaft 10 of the minute-hand. All the gearing may be carried by an arm 19. In a modification, a pin 7<a>, Figs. 7 and 8, on the pendulum 8<a> engages a forked rocking member 1<a>, which is pivoted at a point approximately coincident with its centre of gravity, a brake &c. being applied to control its movement. The pin 7a is only slightly smaller than the slot e<a>, one side of which is faced with silver or other conducting- material, thus causing the pendulum gradually to resume its full movement after its movement has been accidentally reduced. In either of the two modifications the gearing may be carried by a frame consisting of a part 15a to which is secured a piece 16a of square tubing an extension piece 17<a> being secured to the front face of the tubing. Reference has been directed by the Comptroller to Specification 178,482.

Title: The digitization of an analogue value by the extended counting method
IPC: H03M1/00
Filed: 1970-03-24
Abstract: 1300155 Anologue to digital converter SEIMENS AG 24 March 1970 [24 March 1969] 14337/70 Heading G4H  An anologue to digital converter detects the maximum value of a pulse with a voltage discriminator M and the voltage discriminator M activates switch S 0  to isolate capacitors C 1  and C 2  which thus store the maximum anologue input. In synchronism with the trailing edge of the first clock pulse to be emitted oscillator TG, following the activation of switch S 0 , logic unit L causes switch S 1  to close and capacitor C 1  to discharge into current sink Se 1 . One clock pulse later switches S 2  and S 3  are closed so that C 2  discharges at the same rate as C 1 , into sinks Se 2  and Se 3  whose combined correct capacity is the same as that of Se 1 . The instant at which the potential of C 1  reaches zero is detected by detector NL1. This causes switch S 3  to open on the arrival of the trailing edge of the next clock pulse, and the counter (not shown) recording the clock pulses to change the weight assigned to each clock pulse. The capacitor C 2  thus discharges at a slower rate and the clock pulses recorded during its discharge have a lower weight. Thus the system has a coarse and fine scale. A second embodiment giving two progressively finer scales and employing four capacitors is also described.

Title: Improvements in or relating to pneumatic jacks, shock absorbers or the like
IPC: F16F9/04
Filed: 1922-05-23
Abstract: 202,724. Hales, S. E. May 23, 1922. Pneumatic springs.-In a pneumatic shock-absorber of the kind comprising a piston and cylinder adapted to move relatively to each other and in which is employed a known form of packing comprising a flexible tube doubled back and rolling over itself, the packing 5 is clamped on to a piston 6 by a plate 4 which also guides the piston in the cylinder 3. The packing is doubled over the open end of the cylinder and secured by binding. A tube 10 contains a wooden filling piece 11 clamped between plates 12, 6 and provided with a liner 11<a> in which is slidably mounted a head 15 having a series of holes 16 that can be engaged by a pin 16a resting on the plate 12. The packing is confined by a tube 17 provided at its upper end with a flanged ring 19 which forms a guide for the tube 10 and limits its travel. In order to allow the piston to be raised slightly beyond the normal, the ring 19 is connected to the base by a strip 20 of flexible material which is bent at 21. The flexible tube 27 through which air is supplied passes through normally aligned apertures in a plate 25 upstanding from the base and a plate 24 which is connected to the ring 19 by a strip 22. When the ring 19 is raised, the tube 27 is nipped and the air supply cut off. The appliance can be used as a shock absorber by attaching the cylinder or piston to the springs, or axle, or chassis of a vehicle and filling it with air at a suitable pressure.

Abstract: 242,193. Robson, W. H., and Leggo, H. M. June 8, 1925. Rolling.- Relates to a double machine and consists in using another roller, or an adjustable member having a series of surfaces, to form with the primary rolls a recess or hopper to receive the molten glass and thus replace the " teeming plate " usually employed. The primary rolls consist of a lower pressing-roll 1, Fig. 1, and a companion pressing-roll 2 which is arranged somewhat above the roll 1. A third roll B is placed on the opposite side of the roll 1 and somewhat higher than the roll 2, the three rolls forming between them a space A which serves as a hopper for the reception of the molten metal. The roll B is rotated with the other rolls and is placed sufficiently close to the roll 1 to prevent the metal from escaping between them. In a modification the roll B is replaced by a block C, Fig. 3, having a series of surfaces a, b, c, d, any one of which can be brought into position to form a wall of the hopper.
