Title: Improvements relating to respiratory appliances for protection against noxious gases
IPC: A62B18/00
Filed: 1934-07-17
Abstract: 438,980. Respiratory apparatus. SMITH, A. LEIGH-, 30, Smith Square, Westminster, and RICHARDSON, H. O. W., 24, Adelaide Road, Hampstead, London. July 17, 1934, Nos. 20884 and 21804. [Class 81 (ii)] In respiratory apparatus for protection against noxious gases comprising a pump, an air purifier and a reservoir leading to one or more masks, the pump preferably comprises a bellows 1 and forces air through a purifier 2, on which the bellows may be mounted, into the reservoir 4 which is of flexible material and devoid of internal operating devices. The reservoir 4 leads through a non-return valve 5 to a mask from which air is exhaled through a valve 6. The bellows 1 is preferably carried on a body belt 3. An additional pipe may lead from above the valve 5 to a separate mask for a child. In a modified construction a separate bellows leads to an elongated filter canister connected by a tube to a point between the valve 5 and a reservoir closed at the bottom, a valve cutting off the reservoir in case of damage being provided. For supplying a number of persons a bellows and an elongated canister with a screw cap are mounted on a separate stand, the canister being connected through branching pipes, through a large reservoir to individual masks, or to individual reservoirs and masks. The canisters may contain a cotton-wool filter, alkaline and drying filter material such as soda-lime and calcium chloride, and adsorptive charcoal, and a wet filter for humidifying the filtered air may be connected between the canister and the reservoir. One of the Provisional Specifications describes the purifying components as contained in tubes, the cotton wool being enclosed in a wide, and the charcoal in a long, closable tube. The other Provisional Specification refers to a filter canister in which the soda lime is carried in a separate removable container.

Title: An improved metal feeding device for melting pots
IPC: B41B11/82
Filed: 1938-07-14
Abstract: 517,466. Feeding metal to melting-pots. KLINGE, W. H. E. July 14, 1938. No. 20886. [Class 51 (ii)] [Also in Group XVI] In a device for feeding metal to a metal-pot, in which an ingot is suspended from a line passing over a rotatable drum having means such as clockwork for controlling the feed, the drum is arranged for vertical displacement within a fixed housing, which has means co-operating with the feed-controlling means to maintain a uniform speed of rotation of the drum irrespective of alterations in the weight of the ingot. The ingot is suspended. from a wire 14 passing around a drum 9 mounted in a housing 3, which can slide vertically in a fixed housing 1 and is supported by springs 6. Rotation of the drum is controlled by clockwork 19, the pendulum 20 of which passes through a ring 28 carried by the fixed housing. The weight of a fresh ingot draws the housing 3 down, so that the ring 28 allows the maximum swinging of the pendulum. As the ingot melts and its weight decreases, the springs 6 raise the housing 3, so that the ring 28 increasingly restricts the swing of the pendulum, and the speed of rotation of the drum remains unaltered. When the metal level rises, a float breaks the circuit of a solenoid 21, so that a brake in the form of a spring pressed bar 22 stops the pendulum.

Title: Improvements in or relating to precision balances
IPC: G01G7/04
Filed: 1959-06-18
Abstract: 880,199. Weighing-apparatus. STEFFES,K. June 18, 1959 [June 28, 1958], No. 20903/59. Class 40 (1). [Also in Group XL (b)] A precision balance contains an auxiliary beam which is caused to follow the movement of the main beam by a closed-loop servo system, the deflection of the main beam being sensed by a magnetic coupling or by photoelectric means. In the Figure, the balance beam 1 carries the core 6 of a differential transformer whose primary 5a is energized from a current source 9. When the beam is deflected an output is obtained from the secondary 5b as a voltage whose phase sense depends on the direction of deflection of the beam. This voltage is amplified at 14, passed through a conventional " proportional-differential " anti-hunting network 15 and applied to a motor 11 to cause it to run in one direction or another according to the displacement of the beam. The motor rotates a shaft 19 through gearing 17 and also drives a digital indicator 22. The shaft drives a nut 20 which bears against an auxiliary beam 3 and thus moves the transformer secondary 5b to a new null position. Movement of this auxiliary beam can be used in known matter to provide a remote indication of the position of the balance beam. The digital indicator 22 is calibrated in tens and, for establishing the initial and terminal points of the deflection of the balance, contains a unit of ten or part thereof more than is required for the deflection. The differential transformer can be replaced by a light source on the beam co-operating with a pair of photo-cells. The apparatus can be used for tolerance weighings.
