Title: Improvements in mass flowmeters
Inventor: FISHMAN BERNARD
IPC: G01F1/78
Filed: 1962-09-22
Abstract: 975,712. Measuring fluid flow. FLO-TRON Inc. Sept. 22, 1962, No. 36119/62. Heading G1R. A meter for measuring the mass flow rate of a fluid comprises a conduit with means for measuring pressures at localities spaced along the length of the conduit and means for subtracting a portion of the main flow from one of these localities and adding it at another. The pressures are measured by a suitable meter 9 connected to a pressure-head differential transducer 8. The subsiduary flow q is propelled by pumps 6 and 7 and may be greater or less in volume than the main flow Q; preferably it is greater to enable small values of Q to be measured very accurately. Alternative arrangements (Figs. 1, 2 and 5 not shown) either omit the orifices 10 and 11, or provide for taking pairs of pressures, one on each side of each orifice with separate transducer and meter for each pair Fig. 6 illustrates an arrangement in which the main flow Q is divided into two equal flows Q-I and I in separate conduits 2 and 3. Each conduit has a pair of orifices 18 and 19; 20 and 21 between which a pump 14 operates to transfer fluid from one conduit to the other whilst the resulting pressures P 2  and P 3  are measured at the points of joinder of the transverse conduit 15. By suitably combining the pressure differences sensed by the transducers according to the system employed the mass flow velocity can be directly derived. Figs. 9 and 11 show a flowmeter based on the arrangement in Fig. 4 where a constant speed motor rotates pump rotors 30 and 32, in a housing 26 where a main inlet 28 and a main outlet 35 open into chambers 29 and 43 respectively. The fluid can flow between the chambers 29 and 43 either through the rotors 30 and 32 or through orifices 33 and 34 (Fig. 11) whilst ducts 39 and 40 connect with a transducer and pressure gauge.

Title: Lead-acid cell
IPC: H01M4/68
Filed: 1971-08-02
Abstract: 1364283 Lead-acid cells GATES RUBBER CO 2 Aug 1971 [3 Aug 1970] 36142/71 Heading H1B A lead-acid cell having no free electrolyte comprises a spirally-wound assembly consisting of positive and negative electrodes 11 and a separator 14. The electrolyte is present in a starved amount so that nearly all of it is absorbed in the separator and only a thin film is present on the electrodes. The electrodes are formed of expanded lead grids which are pasted with active material. The preferred separator material is fibreglass. The spiral assembly is held under pressure in a steel casing 15 having an insulating lining 18 of plastics material. The negative electrode has a greater capacity than the positive electrode so that negligible hydrogen is evolved and the oxygen is removed by reacting with the active material on the edges of the negative electrode. Above a certain pressure oxygen is released from the cell by a resealable valve 23 and vent 32. Droplets of electrolyte entrained in the oxygen escaping through the valve 23 are absorbed in sodium bicarbonate 26. current from the positive and negative electrodes 11 is conveyed, respectively, to a metal cap 19 and the casing 15, by corresponing tabs 17 positioned at intervals along the electrodes. In a modification (Fig. 3, not shown) the electrodes and separators form a stack of flat sheets.

Abstract: 846,875. Testing physical qualities of fabrics. TOOTAL BROADHURST LEE CO. Ltd. March 18, 1957 [Dec. 19, 1955], No. 36369/55. Class 106 (2). [Also in Group XX] A method of testing the crease resistance of a textile fabric comprises the steps of (a) forming two oppositely directed parallel creases in a specimen 1 by holding it in folded S or Z form for a prescribed period of time under a prescribed pressure; (b) laying the specimen 1 on a flat surface 13; and (c) measuring optically the inclination X to the surface of a band 9 of the fabric limited by the creases. After wetting the specimen 1 in a bath 2 and mangling it between rollers 3, it is placed on a platform 4. A fold plate 5 is pushed along a guide to overlie part of the specimen which is then folded back over a straight edge 6. Another fold plate 8 is pushed along its guide toward the platform 4 and then the guide is raised and lowered by an eccentrically mounted roller to bring the plate 8 down on the folded specimen which is folded back again over the plate 8. Another plate 10 is lowered on to the specimen, the plates 5, 8 are withdrawn and a weight 11 is brought down on to the plate 10 for a set time. The creased specimen is suspended in a drying chamber 101. Before and/or during and/or after drying it may be suspended from a vibrating arm for a predetermined time. The specimen is finally placed on a table 13 with its upwardly concave crease coaxial with a crank arm carrying a lamp case and providing a slit source of light. The lamp is swung from position 15 to 14 where the upwardly convex crease 18 first throws a shadow on the concave crease 17. The angle X may be read from a scale (see Group XX) and the average reading over several taken with the specimen each side up provides a measure of crease resistance.

Title: Radio beacon receiver
IPC: G01S1/02
Filed: 1956-11-30
Abstract: 838,847. Phase measurement. STANDARD TELEPHONES & CABLES Ltd. Nov. 30, 1956 [Dec. 1, 1955], No. 36678/56. Class 37. [Also in Group XL (c)] Relates to a receiver for use in conjunction with a radio beacon (see Group XL (c)) having a directional pattern, Fig. 1, rotating at f c/s. and comprising a major lobe 1 and eight minor lobes 2 such that the modulation envelope, Fig. 4 (not shown), of the signal received at the mobile receiver comprises a fundamental bearing signal of frequency f c/s. and a harmonic bearing signal of frequency 9f c/s. the phrases of these signals relative respectively to fundamental and harmonic reference signals of corresponding frequency providing coarse and fine indications of the bearing of the receiver from the beacon. According to the present invention the receiver is such that under normal conditions a single bearing indicator is controlled by both the fundamental and harmonic phase comparators to provide an unambiguous bearing indication whose accuracy is determined by the harmonic bearing signal but when the amplitude of the harmonic bearing signal falls below a threshold value then the indicator is controlled only by the fundamental phase comparator. Means are also provided for indicating if the amplitude of the fundamental bearing signal is below a threshold value. In the embodiment illustrated in Fig. 8 the relays are shown in their de-energized condition. The fundamental and harmonic reference signals are applied directly to respective phase comparators 32, 34 and the fundamental and harmonic bearing signals are applied thereto through geared phase shifters 31, 33 controlled by a D.C. servomotor 38 having a single field winding 37. The fundamental and harmonic bearing signals are also applied to relays 39 and 40 respectively so that under normal conditions when the amplitudes of these signals exceed their threshold values, relays 39 and 40 are energized thereby connecting the armature 39b to contact 39a and disconnecting the armature 40b from contact 40c. If there is an error output from the fundamental phase comparator 32, relay 36 is energized thereby applying the error signal to the servomotor 38 which adjusts the phase shifters 31, 33 to reduce the error signal to zero. Relay 36 now de-energises thereby applying the output from the harmonic phase comparator 34 to control the servomotor 38 so that the accuracy of the final position of the phase shifters as shown by an indicator 35 is determined by the accuracy of the harmonic bearing signal. If the amplitude of the harmonic bearing signal falls below its threshold value, relay 40 de-energizes thereby applying the output from the fundamental phase comparator 32 to the servomotor 38 through a resistor 41 which serves to delay the control action. If the amplitude of the fundamental bearing signal also drops below its threshold value, the relay 39 de-energizes thereby connecting the field finding 37 of the servomotor 38 to a D.C. voltage which causes the motor and indicator 35 to hunt continuously.
