Title: Electro-therapeutic apparatus
IPC: A61N1/32
Filed: 1937-12-07
Abstract: 506,544. Supply systems for consumption apparatus. ASSOCIATED P.A. EQUIPMENTS, Ltd., and DENNY, B. Dec. 7, 1937, No. 33875. [Class 38 (iv)] Periodic variation of the intensity of pulsating electric potentials supplied to electrotherapeutic apparatus is obtained by means of a resistance capacity timing circuit controlling a thermionic valve in the supply circuit. The secondary of an input transformer 6, the primary of which is supplied with alternating or intermittent current, and the primary of an output transformer 5, the secondary of which supplies the electro-therapeutic apparatus, are connected in series with a source of direct current A-B between the anode and cathode of a threeelectrode thermionic valve 4. The intensity of the pulsating electric potential available at the secondary terminals of transformer 5 is controlled by a biassing circuit which controls the potential applied to the grid of valve 4. The cathode and control grid of valve 4 are respectively connected to the movable contacts of potentiometers 8 and 7, provided for adjustment. Potentiometer 8 is connected directly across a source of direct current EF while potentiometer 7 is in series with a resistance 10 and a change-over switch 9 across the same source. Operation of the switch 9 changes the potential applied to the grid of valve 4. Auto. matic operation of this switch to produce a periodic variation of the intensity of the pulsating potential output is effected by a time-base circuit in which a change-over switch 13, mechanically coupled to switch 9, is operated periodically by electromagnet 14. The winding of this electromagnet is energized from the terminals of a condenser 18 charged from a direct current source C-D via switch 13 and resistance 15. The cycle of operations in this circuit is the charging of condenser 18 to the potential at which electromagnet 14 changes over switch 13 whereupon condenser 18 discharges through resistance 15, switch 13 returns, and charging starts again. A potentiometer 16 is provided to vary the charging and discharging time periods and a resistance 17 is connected across the direct current source. Condensers 11 and 12 are included in the biassing circuit to modify the rate of change of potential on the valve grid, and in a modification, Fig. 2 (not shown), these condensers are associated with potentiometers for adjustment. In this modification, the source of direct current for the anodecathode circuit is obtained from the alternating or intermittent current source by the use of centre - tapped transformers and diode thermionic rectifiers, while in a further modification, Fig. 3 (not shown), these diodes are replaced by Argon-filled thermionic relays having grid electrodes, the potentials of which can be varied by potentiometer to alter the output waveform. In this latter modification, the biassing and time-base circuits are combined in one circuit.

Abstract: 1482862 Diagnosis of septicemia WADLEY RESEARCH INSTITUTE & BLOOD BANK, J K & SUSIE L 15 Aug 1975 [20 Dec 1974] 34077/75 Heading G1B [Also in Divisions B8 and C6] A device for mixing and centrifuging a sample fluid, e.g. blood suspected of containing microbial pathogens in the diagnosis of septicemia, consists essentially of an enclosed vessel 10, Fig. 1, of glass, polycarbonate or polypropylene, containing an evacuated centrifuging chamber 24, self-seating rubber stoppers 14, 16 and a thin rubber membrane 20 stretched over the opening of a recess 16a in the stopper 16. The web 16b of stopper 16 is made thicker than that of stopper 14. The evacuated chamber 24 contains a liquid filter medium 22 having a specific gravity sufficiently high e.g. above 1À06, to suspend red and white blood cells or cell debris, while being receptive to any microbial pathogens. The medium includes a water-soluble solute preferably sucrose, or an epichlorohydrinsucrose copolymer or dextran of refined properties, thermally sensitive gelling agent, reducing agent and oxygen-sensitive dye specified. A typical solution contains 100 parts sucrose, 3 parts gelatine, 0À8 parts of L-cystine and of sodium thioglycolate, 0À0003 parts resazurin and 97 parts water (pH 6À0). Recess 16a contains blood anticoagulant and a lysing agent for blood cells e.g. an agreous solution containing 2% sodium polyanethole sulphonate and 12% non- toxic saponin. In use the device is first chilled sufficiently to solidify the filter medium. The blood sample 26, Fig. 4, is syringed into the evacuated chamber (24) by a hypodermic needle 28 which penetrates stopper (16) and membrane 20, thereby releasing the anticoagulant solution (18) with the sample. Thereafter the device is heated sufficiently to liquefy the filter medium, the combined contents of the chamber are centrifuged and the microbial pathogens brought into the filter medium are taken off with a syringe 32, Fig. 7, for microbiological culturing. It is arranged that the needle 34 of this syringe is too short to penetrate through the other stopper 16.

Title: Field deflection circuit
IPC: H04N3/233
Filed: 1974-08-02
Abstract: 1475135 Sawtooth deflection PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Aug 1974 [6 Aug 1973] 34176/74 Heading H3T A circuit arrangement to supply a sawtooth waveform corrected current to a television field deflection coil has a sawtooth generator 6 connected to an amplifier 19 and has a feedback circuit 8 having an input 28 to receive information relating to the deflection current and an output 41 for feedback to a first input of a first signal combining circuit 18 whose second input is connected to the sawtooth generator. In the feedback circuit 8 the output of a first integrator 30 is connected to one input of a second combining circuit 35 and through a second integrator 32, 33, 34 to the second input, the output of the second combiner 35 being fed to a circuit 39, 40 to combine with the input to the first integrator, the output of the third combiner being connected to the said first input of the first combiner 8.  To avoid the need for the fedback signal to be larger than the signal derived from the current and thus reduce oscillation risks, the sawtooth is made non-linear, the ramp being a curve of parabolic form lying above the linear at all points. The parabolic non-linearity is obtained by simultaneously feeding back the output voltage via resistor 17 to an input which is biased to an appropriate mean D.C. level by the divider chain 15, 16. The majority of the circuit can be integrated in a semi-conductor body. The circuit is said to give linearity deviations of less than 0À3% after adjustment of the controls, said to be simple and independent. The S correction being set by 33 and the parabolic correction by 38. The feedback loop also automatically adjusts the D.C. level of the deflection current to the correct value.

Title: Device for the treatment, especially heating, of elongated articles, for example meat sausages
IPC: A47J37/06
Filed: 1968-07-18
Abstract: 1,215,337. Feeding articles. DWN AUTOMATENBAU G.m.b.H. 18 July, 1968 [18 July, 1967], No. 34179/68. Heading B8S. [Also in Division A4] In an automatic vending machine, a sausage is fed down a shaft (11, Fig. 2) to a trough 9 which is in the upwardly open position, and a first winding of an electromagnet (6, Fig. 2) is energized and moves a fork-like linkage 8, which rotatably mounts trough 9 about a horizontal axis, to the left to close trough 9 (Fig. 4), this movement being retarded by a damper (30, Fig. 2). The closing actuates a switch (15, Fig. 2) which operates a time switch (16) which, after a predetermined time, energizes a second winding of magnet (6) for opening the trough. While it is closed, the sausage is heated by microwave energy from a chamber 3 separated from trough 9 by a cover 33 and insulation 26. The second winding moves linkage 8 to the right, and, during the initial part of this movement, the trough is held closed by a detent 13 engaging the upper edge 10a of trough flange 10. At the middle part of this movement, the lower edge of the trough flange moves away from the cover and the trough rotates to the downwardly open position (Fig. 5) and the sausage drops down into the dispensing part (12). During the final part of this movement, the detent 13 releases the upper edge of the trough, and the latter rotates to the upwardly open position for the reception of a fresh sausage. The last rotation occurs either because the rotational axis of the trough is offset towards the trough opening in relation to its gravity axis, or through a tension spring 31. The trough mounting comprises stubs (24) received in bores in the two prongs of linkage 8, and one or both of these bores may comprise upwardly open slots. The sausage may alternatively be heated by infra-red radiation or steam.

One side b of the mould is pivoted to the roller g and i and can be moved by a lever j. When the mould is full the roller g is rolled over so that the mould becomes lowermost and inverted and the lever j is operated so that the side b is moved clear of the casting therein which is therefore deposited on the ground, and the roller g is then rolled clear. The roller g can be raised by levers k to transport it on the carriage c. Rails may be provided for the wheels d, and semi-cylindrical tracks g<1> may also roll on them. Means for vibrating the mould and for reinforcing the casting and giving it any desired shape may be provided. The Provisional Specification mentions that the base on which the roller g rolls may be slightly inclined to cause rolling in the direction to deliver the casting, that the roller may also have wheels to assist in positioning it, and that the bottom of the measuring box may be slidable or pivoted and can be displaced to discharge the concrete into the mould by the final movement thereof, the mould in this case being brought under the box.
