Filed: 1925-01-22
Abstract: 229,643. Braunstein, B. Feb. 21, 1924, [Convention date]. Capsules.-In a collapsable metal container or capsule for medicaments of the kind in which one half of the capsule is adapted to be forced into the other half by a pressure member so as to eject the contents, the lower half of the container is formed with a nozzle 20 and finger pieces 21, Fig. 1, and is made of thicker material than that used for the upper half 19 which is adapted to be forced into the lower half by a pressure member 22 carried by a thumb ring 23. The Specification as open to inspection under Sect. 91 (3) (a) refers also to capsules made of metal of uniform thickness or of gelatine or paraffined paper and describes the form shown in Figs. 1 (Cancelled) and 2 (Cancelled), wherein a. spherical capsule 7 with a neck 8, closed in known manner by a headed pin 10, is placed in a cylindrical barrel 1 having a hemispherical seating at its lower end, and is acted upon by a hemispherical plunger 11 which is smaller than the seating by the thickness of the two walls of the capsule when collapsed as shown in Fig. 2 (Cancelled). In a modification, Fig. 3 (Cancelled), a capsule of the shape shown is placed in a barrel comprising two parts 14, 15 connected bv a bayonet joint, and is acted upon by a plunger 17 guided by a cap 18 sliding over the barrel. The shape and dimensions of the parts 13, 16 of the capsule and of the plunger 17 and the part 14 of the barrel are such that the capsule may be completely collapsed. This subject-matter does not appear in the Specification as accepted.

Title: Frequency modulated oscillator
IPC: H03C3/14
Filed: 1946-01-22
Abstract: 613,855. Frequency modulation; testing tuned circuits ; BRITISH THOMSONHOUSTON CO., Ltd., and KING, A. H. Jan. 22, 1946, No. 2105. [Class 40 (v)] In a frequency modulated oscillator having a thermionic reactance in shunt with its tuned circuit, the magnitude of the thermionic reactance is controlled by a resistance and condenser in series, the condenser being connected between the cathode and grid of the thermionic reactance and varied with a main tuning condenser. As shown, a thermionic reactance V2 is connected across the tuned circuit 4, 3 of an oscillator V1. A modulating voltage, which may be derived from a oscilloscope time-base circuit, is applied to the control grid of the reactance 15. The quadrature voltage for the grid of V2 is taken from the junction of resistance 10, and condenser 11, which is ganged with tuning condenser 4 of the oscillator VI. Condenser 11 is arranged to follow <3>/2 power law with respect to condenser 4. This ensures that the frequency sweep of the oscillator remains constant at different mean frequencies. The condensers 4, 11 may follow the same law, and a shunt trimming condenser 14 and padding condenser 13 be provided to make the effective capacity in the tuned circuit follow the rerequired law. The oscillator may be used to test tuned circuits.

Abstract: 524,101. Machinery guards. LAWRENCE, R. S., [trading as LAWRENCE & CO., R. S.], and COLLINS, J. Jan. 21, 1939, No. 2197. [Class 80 (iv)] Relates to machines, e.g. a press for cutting soles from leather &c. dn which a movable cutting tool &c. is adapted to be adjusted by hand over the material to be cut and is of such a depth that when engaged by the movable part of the machine, there is sufficient space for the hand of the operator to grip the tool and hold it during the cutting operation. According to the invention, a guard is mounted on the machine to serve as an obstruction to prevent the operator from adjusting the tool unless he so grips it that his fingers cannot be caught between the tool and the movable part of the machine. The guard may comprise a bar a secured in brackets b<2> on the machine frame b' close to the movable head b of the press. The height x of the guard above the fixed table c is such that the tool e can only be inserted and adjusted by gripping it around the sides. The bar may be adjusted in height by a worm and worm-wheel adjusting cams. In modifications, (1) the guard may be a transparent panel, (2) may be a ring - shaped member coaxial with the movable member of the press. When the guard is removed from its operative position it may disengage the driving clutch.

Abstract: 1486871 Hydrogen fluoride removal VEREINIGTE ALUMINIUM WERKE AG and METALLGESELLSCHAFT AG 22 Jan 1975 [24 Jan 1974] 2882/75 Addition to 1474215 Heading C1A [Also in Division C7]  In a process for the removal of hydrogen fluoride from exhaust gases of electrolytic aluminium production, by introducing the gases into a fluidized bed reactor containing solid absorbent for HF such that the solids concentration in the expanded fluidized bed decreases upwardly and from which the absorbing solids are discharged upwardly and subjected to solid-gas separation by elastrostatic precipitation, the improvement comprises removing solid impurities from the gases in an additional electrostatic precipitatior before introduction into the reactor. In one embodiment (see Figure), the crude gas is conditioned with water in chamber 1, and a major part of dust impurities are separated in precipitator 3 and fed to pyrohydroylsis furnace 5, from which the purified gas flows into fluidized bed reactor 7 and is contracted with alumina absorbent 8 to which water is added via conduit 9. The gassolids mixture passes into a second electrostatic precipitator 12 which is divided into several electric fields. Pure gas leaves the electrostatic precipitator 12. The fraction of separated solids having the lowest impurity content is withdrawn from dust-collecting bin 13, and heat-treated in rotary kiln 17, and can then be fed to the electrolytic bath. The majority of dust collected in precipitator 12 is discharged from dust-collecting bins 14 and returned to fluidized-bed reactor 7. The expelled gases from pyrohydrolysis furnace 5, containing mainly HF are fed to fluidized-bed reactor 7 together with the exhaust gases from the rotary kiln 17.

Abstract: 1404071 Refuse vehicle container charging DOBSON PARK ENG Ltd 15 Jan 1974 [20 Jan 1973] 3074/73 Heading B8E A refuse vehicle has a charging hopper 14 and a main chamber 13 to which compressed refuse is fed by a transfer device comprising a compactor 28 operated by a ram 30. Initial compaction occurs against a gate 40 in its closed position while a compacting face 29 enters the main chamber to compact its contents. The arrangement is such that from the initial position, Fig. 4A, the compactor 28 advances until the pressure of the refuse on the gate 40, Fig. 4B, triggers a pressure sensitive device which causes hydraulic means to open the gate, Fig. 4C, allowing the compactor 28 to complete its stroke when the gate 40 is caused to again close, Fig. 4D, its plate 42 clearing refuse from the working face 27 of the compactor 28.

Title: Improvements in or relating to circuits for automatic control of the frequency of anoscillator
IPC: H04N5/12
Filed: 1952-02-06
Abstract: 700,056. Automatic frequency control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 6, 1952 [Feb. 9, 1951 ], No. 3116/52. Class 38 (4). [Also in Group XXXVI] The frequency of an oscillator 1 is automatically controlled by applying sawtooth voltages 5 derived from the oscillator to the anodes of two discharge tubes 8, 11 and by applying pulsatory positive voltages 2 (which may be part of a television wave form 3) to a control grid 14 of one of the tubes. The resulting positive voltage pulses across the resistor 17 at the cathode of the tube 11 are transferred through a condenser 18 to the cathode of the tube 8, so that the gridcathode voltages are in opposed sense in the two tubes. The D.C. anode circuits for the two tubes are completed by anode resistors 19, 20 and cathode resistors 13, 21 and 17, 22. If the sawtooth voltage is not in desired phase relation with the pulsatory voltage, the current rises in one valve and falls in the other, giving rise to a difference voltage across the resistors 21, 22 which is applied through a resistor 25 to adjust the frequency of the oscillator 1. The tube 11 is a screen-grid tube, and self-biases its control grid, owing to the action of the condenser 15 and resistor 16, to such an extent that the picture signal 3 is clipped.
