Abstract: 228,896. Peccaud, C. Feb. 6, 1924, [Convention date]. Compound-lever apparatus; pendulum-weight apparatus.-In an automatic weighing-scale of the kind in which the action of the load is transmitted to an indicating system by means of a flexible band acting on a rectifying cam, the indicating system comprises a hand or pointer, an upwardly-directed toothed sector movable with the hand or pointer and a light auxiliary pointer actuated by a pinion which rests on the sector. In the form shown, the scale pan l is supported on compound levers m, n coupled by a flexible band a to a rectifying cam b and pendulum d. A toothed quadrant f on the cam shaft carries a pointer k which indicates units of weight against a scale j carried by a stationary dial i. The quadrant f actuates a pinion g resting on the teeth of the quadrant and carrying a pointer h for indicating on the dial subdivisions of the scale j. A second pointer h may be arranged at the other side of the dial i. In a modification, the, pointer k instead of being on the quadrant f, may be fixed to one of the levers m, n. In further modifications the pointers and their dials may move in opposite directions.

Abstract: 702,542. Electromagnetic switches. STONE, & CO. (DEPTFORD), Ltd., J. Jan. 22, 1952 [Feb. 9, 1951], No. 3237/51. Class 38(5) [Also in Group XXXV] A cut-in and cut-out relay 2, for train lighting equipment wherein a generator 4, on attaining sufficient voltage, operates the relay to close contacts 8 which energize a contactor 7 which closes contacts 3 leading to the battery 5 and load 6, has a yoke with three limbs 13, 14, 15 an armature 16 rockable about the pole of the middle limb 14, and voltage and series windings 9, 11 on the limbs 13, 14. In a practical embodimenit, Fig. 2 (not shown) the armature is pivoted on a blade spring. The voltage and series windings assist each other normally, but should there be a reverse current in the series winding due to drop of voltage from the generator, the windings oppose each other and the contacts 8 open, causing in turn the opening of contacts 3. Any delay in the opening of the contacts 3 would not cause a reclosing of contacts 8 since although there might be a large reverse current from the battery through the coil 11 the flux from this would mainly traverse a lock-out magnetic circuit 14, 15 and tend to hold the contacts open. The contactor 7 may have auxiliary contacts which connect an additional resistance in the circuit of the winding 9.

Title: Improvements in or relating to brakes
IPC: F16D65/22
Filed: 1941-03-11
Abstract: 547,827. Internal shoe brakes. BENDIX AVIATION CORPORATION. March 11, 1941, No. 3328. Convention date, April 27, 1940. [Class 103 (i)] A fixed hydraulic cylinder 16, which has a floating action through thrust rods 18, is employed to apply brake shoes 11, 12 by acting upon levers 19, which are made to tilt so as to apply downward forces at 24 on the lower shoe 12 and, by means of turnedover parts 25, upward forces at 26 on the upper shoe 11. The shoes are arranged to anchor individually at opposite ends in forward and reverse braking, the upper shoe 11 engaging anchors 14, 15 at 39 and 40; and the lower shoe 12 at 41 and 42. The shoe return springs 46 and 47 are fitted with additional springs 48, 49, each acting on one shoe only, to hold the left-hand end of shoe I against its anchor away from the drum until the left-hand end of shoe 12 has made contact with the drum and to hold the right-hand end of shoe 12 against its anchor away from the drum until the left-hand of shoe 11 has made contact with the drum; this action is arranged to take place during forward motion to obtain speedy application of the shoes. In a modification the levers 19 may be pivoted to one of the shoes and connected to the other by pivoted links; also in another modification additional force-transmitting members may be interposed between the lower ends of the levers 19 and the ends of the lower shoe 12. An emergency brake-applying means acts upon levers 29a, which are pivotally mounted in slots of the backing-plate and engage in notches 28 of levers 19, by means of a cable. Specification 444,614 is referred to.

Title: Method and device for the economical operation of furnaces, more particularly furnaces of steam generators
IPC: F23N3/08
Filed: 1927-02-08
Abstract: 277,224. Roucka, E. Feb. 8, 1927. Air supply and draught, regulating.-A method of operating groups of furnaces, particularly steam boiler furnaces, in which each furnace has regulating means of the type in which two pressure-sensitive members acted on by forces varying according to the total load of the plant and the load of the individual furnace respectively, together operate a servo-motor to adjust the air supply or draughts consists in cutting out the action of the first sensitive member in the regulators of one or more furnaces when the total load of the plant decreases, and loading the second sensitive member by an adjustable force which maintains these furnaces in a damped condition. In front of the flue damper 10, a pipe 16 opens into the boiler flues 6 and leads to a box 18 closed by a diaphragm 18<1>. A rod 20 fixed to the diaphragm is connected with a lever 22 pivoted on a displaceable roller 24, and the other end of the lever is acted on by a diaphragm 28<1> closing a box 28 connected with the main steam pipe by a pipe 29. To the rod 20 is connected the pistonrod of a valve 14 controlling a servomotor 12 for adjusting the damper 10. The fluid pressures acting upon the diaphragms are counteracted by a weight 30 and two springs 32 34, the spring 34 being connected to a lever 36 pivoted at 40 and normally held by a spring 42 against a stop. The end 44 of the lever 36 is adapted to be raised by a earn 46 to partially or completely relax the spring 34. Connected with the cam 46 is another cam 48 adapted to raise the lever 22 off its supporting roller 24, thus interrupting the action of the diaphragm 28<1> upon the diaphragm 18'. In normal working, the door 8 of the ashpit 4 is open and the flue damper 10 is adjusted in accordance with variations in the steam pressure until a maximum steam pressure is reached whereupon the diaphragm 28<1> raises the lever 22 off the supporting roller 24, so that the springs 32, 34 act alone upon the diaphragm 18<1> and the damper 10 is adjusted in accordance with variations in the pressure of the flue gases. When it is desired to damp the boiler, the ash-pit door 8 is closed and the cams 46, 48 turned to raise the lever 22 off its supporting roller and relax the spring 34 so that the load on the diaphragm 18<1> corresponds to a light draught. In a modification variations of steam pressure are made to alter the position of the displaceable roller upon which the lever pivots, and only the diaphragm acted on by the flue gas pressure is connected with the lever and balanced by two opposing springs. To change over the regulator to give the damped condition, one of the springs is relaxed, lifting the lever off the displaceable roller on to a fixed roller, so that the influence of the steam pressure is cut off and the furnace is regulated according to the light draught when in the damped condition. The air supply to the ashpit may be regulated instead of the flue damper.

Abstract: 1,248,655. Puffing cereals. R. & W. PAUL (MALTSTERS) Ltd. 28 April, 1970 [29 April, 1969; 24 Jan., 1970], Nos. 21661/69 and 3542/ 70. Heading A2Q. A method of disrupting the structure of particulate cereal materials, i.e. whole or partially or completely dehusked ungerminated or germinated cereal seeds or particles of same having a size of 1 m.m. diameter or more, comprises subjecting the particles to the action of radio frequency waves at a frequency of between 30 and 80 Mc/S for a period and at an intensity sufficient to cause complete disruption of the endosperm structure and hence puffing of the particles. The two examples given relate to such disruption of barley grains in the preparation of either an animal feed or a fermentable syrup. In the first example, barley grains having 12 per cent moisture content were placed as a layer 2 cm. thick between the electrodes of a dielectric heating unit operated at a power of 3KW, the layer being passed between the electrodes at the rate of 2 feet per minute. The moisture content of the resulting puffed grains was 4 per cent. In the second example, the unit was operated at a power of 5KW and a layer of barley having 15 per cent moisture content was conveyed as a layer about 6mm. thick on a silicone-rubber bonded fibre glass conveyor at the rate of 50 cm. per minute. The resulting puffed grains had a 5 per cent moisture content. In the preparation of a brewers' extract from the puffed barley the percentage extract obtained was increased, as compared with untreated barley, from 61.8 per cent to 76.2 per cent.

Abstract: 104,874. Reeser, W. E., and Willes, A. van. March 13, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Plastic compositions containing albuminous matter, gelatine, glycerine, and sugar; plastic compositions containing india-rubber.-Relates to rubber substitutes of the kind which are made by treating, under the influence of light, mixtures of collagenous substances and hygroscopic substances, with or without fillers, with chromates, bichromates, or other oxidizing-agents, the influence of light and the rate of oxidation being reduced by the addition of dyes, preferably in the presence of mineral oils, fats, &c. The invention consists in dissolving in the glycerine substances which increase its viscosity, such as carbohydrates, for example saccharose, dextrose, or other sugars, or a sugary syrup, gum arabic, or dextrine. Such substances must not increase the hygroscopicity of the glycerine. As filler, a very absorbent substance is used, such as kieselguhr; the treatment is carried out in a solution of borax or other alkali, and a little phenol or one of its homologues is added. The mass is protected from the action of air and light until the final heating, and the heating is continued, for example at a temperature of 80‹ C., until all water is removed, air being passed through the mass during the process. Either aniline or mineral dyes are employed. The following is an example of proportions : Gelatine 50 parts, glycerine 65 parts, saccharose 50 parts, kieselguhr 20 parts, colcothar (red) 12 parts, zinc white and paraffin oil each 5 parts, borax and potassium bichromate each 1 part, and 5 drops of a 10 per cent. solution of phenol.

Title: Formant vocoder utilizing resonator damping
IPC: G10L19/00
Filed: 1969-01-23
Abstract: 1,261,552. Formant vocoder. PHILCOFORD CORP. 23 Jan., 1969 [25 Jan., 1968], No. 3859/69. Heading H4R. In the speech synthesizer of a formant vocoder the formant resonators are heavily damped for a short time prior to the application of each excitation pulse. Fig. 1 shows a formant vocoder in which the analyser derives signals representing the frequency, F1 &c., and amplitude, A1 &c., of the first three formants of an incoming speech signal, together with a signal P, indicating the pitch frequency and a signal V, indicating a voiced or unvoiced condition. At the receiver synthesizer the pitch signal controls the frequency of pulses which are applied, during voiced sounds, via a gating circuit 10 to modulators 14, 16, and 18 where the pitch pulses are modulated by the respective formant amplitude signals, A1, A2, and A3, filtered by variable frequency resonators whose resonant frequency is adjusted by the respective formant frequency signals, F1, F2, F3, before the signals are further filtered and combined to form the synthesized speech. The variable frequency resonators are arranged to be heavily damped by a pulse derived from the excitation signal immediately before the excitation pulse is applied to excite the filter, so as to eliminate any effect on the output from the filter during one pulse, of the energy still remaining from the previous pulse. Fig. 3 shows a circuit for the synthesis of one formant comprising a resonator 20 including a differential amplifier 44 connected in a loop with variable frequency high pass, 46, and low pass, 48, filters, each of which is tunable by the signal F1 to provide a circuit resonant at F1 formant frequency. The damping circuit, 32, comprises a fet connected from one input of the differential amplifier 44 to earth, and which is switched on just before a pitch pulse is generated via differential amplifier 38 fed with a signal derived from the pitch pulse generator 8. The pitch pulse generator comprises a capacitor 35 charged via the emitter collector path of transistor 33, the impedance of which is controlled by the pitch frequency signal. Just before the charging potential reaches a value to cause a pitch pulse to be generated by pulse generator 41, differential amplifier 38 is switched from negative to positive saturation, as the charging potential reaches the reference potential set by potentiometer 36, causing fet 40 to be switched on and the damping condition to be established. Reference has been directed by the Comptroller to Specification 1,146,184.

Title: Apparatus for indicating, measuring or recording physical or chemical quantities or qualities
IPC: G01B11/00
Filed: 1923-02-12
Abstract: 193,398. Roucka, E. Feb. 14, 1922, [Convention date]. Tell-tale apparatus. - In apparatus for recording &c. physical values of the kind in which an auxiliary value co-operates with the value to be measured so that an impulse of energy is produced when the two values have a predetermined ratio, the impulse is produced by the action of a ray of energy on a sensitive device. As shown in Fig. 3, a member 6 carries a source of light 12, and a selenium cell 14 which forms one arm of a wheatstone bridge, a similar compensating cell 36 being included in another arm. The member 6 is continuously rocked by a cam 26, and when it has a definite position relative to a primary indicating pointer 8, light is reflected from a mirror 10 on the pointer on to the cell 14 for an instant. A magnet 44 is thus energized and a momentary impulse sent from a source 50 to the receiving station to energize magnet 92. The latter moves an arm 90 to press a pointer 84, which is continuously moved by a cam 62 in synchronism with the cam 26, on to a record strip. In a modification, Fig. 5, for measuring a small current from the thermoelement 140, a pointer 152 is acted upon by a coil 136, influenced by the value to be measured, and a coil 138 the current through which is being continuously varied. The pointer 152 carries a shutter 150 moving in the path of a beam of heat from a source 146. The arrangement is such that when the two values have a predetermined ratio a slit in the shutter 150 registers with the beam and allows the thermo-battery 148 to be influenced thereby. The element 148 may be arranged in a wheatstone bridge arrangement similarly to the cell 14, Fig. 3. The coils 136, 138 are arranged in a casing having windows 134 of quartz, rocksalt, fluor-spar, &c., transparent, to heat. In examples (1) light normally falls on the sensitive element and is momentarily interrupted by a shutter controlled by the primary value, and (2) the primary element carries a concave mirror which at the desired moment reflects light on to the edge of a prism which refracts the light to illuminate the sensitive element.
