Title: Improvements in or relating to electrical cavity resonators
IPC: H01P7/06
Filed: 1945-12-21
Abstract: 618,506. Electric resonators. PHILCO RADIO & TELEVISION CORPORATION. Dec. 21, 1945, No. 34711. Convention date, July 12, 1944. [Class 40 (viii)] A cavity resonator, for use in an echo box for radar or for like purposes, can resonate in two modes at different frequencies, one of which is fixed and the other tunable. The fixed frequency may be used for radar and the tunable frequency for receiving beacon signals. The resonator shown in Fig. 3 has a fixed mode in which the electric and magnetic lines are axial and circular respectively and are oppositely directed in the component cavities 25, 26, Fig. 4 (not shown). In a second mode, these lines are in the same direction in both component cavities, and the magnetic lines are continuous through the opening connecting the cavities, Fig. 5 (not shown). In this case the coupling afforded by the opening can be varied, so as to vary the frequency of the second mode while that of the first remains unaffected, by variably closing a metal partition 27. The resonator is excited by means of probes or of loops 33, 36. The component resonators 25, 26 may be relatively slidable along the plane 80; so that they are coupled by an adjustable opening centrally located, the partition 27 being omitted, Figs. 10, 11 (not shown). Alternatively, they may be end-toend, Fig. 12, with a central aperture 75 that can be closed by an adjustable partition 76 or by an iris diaphragm. The partition 76 must be normal to the electric field. The adjustable frequency will be above or below the fixed frequency according as the electric or the magnetic field intensity is high in the neighbourhood of the partition.
Patent GB-411862-A (GB)
Title: Improvements relating to the drawing and spinning of fibrous materials
IPC: D01H7/92
Filed: 1932-12-09
Abstract: 411,862. Drawing and spinning fibrous materials. BARKER, A. F., 2, Shireoak Dene, Shireoak Road, Headingley, and BINKS, C. C., 5, Bewerley Street, Dewsbury Road, both in Leeds. Dec. 9, 1932, No. 34939. [Class 120 (ii).] Cotton, wool, and like fibrous material is formed into twisted sliver, roving or spun yarn by rotation of a free end of the material, the sliver being built up from successive tufts detached from the original material, which may be in the form of slightly twisted sliver, as in English or cone worsted drawing or mule roving, or untwisted sliver as in French drawing. The twisted material is wound on to a double-flanged bobbin, cop, spool or paper tube. Two single threads may be delivered by a pair of delivery rollers or by a trap roller to ring twisting-apparatus. As shown in Fig. 1, the material is fed by rollers a, a<1> to a nip roller c' co-operating with a roller c, Figs. 3<a>, 4 which constitutes the twisting means, and is wound by drum winding-means e. The roller c is provided with a leather, rubber, brass or other surface f and an aperture g, and draws the fibres from the rollers a, a' in the form of tufts, which are carried through the aperture g and a stationary or rotary nozzle h, and are led directly or through a right-angled path to the winding-means. The material is thus built up in the form of tufts and twisted to a degree determined by the ratio of the rotation of the roller c and winding-means. The nozzle h is rotated if false twist is desired to ensure a more regular sliver, roving or thread and to prevent breakage in the case of a softspun sliver, the driving being conveniently effected by a belt l. To ensure more effective tufting the rollers a, a<1> may be intermittently rotated by ratchet mechanism so that delivery of the material is correctly related to the position of the surface f of the roller c. The aperture g may be formed non-centrally on the roller c so that the sliver tends to move spirally on the roller. Rollers b, rotating in a trough containing water, oil, rice-flour, or other substance, may be provided to condition the material and to prevent disturbance due to electrification of the fibres. Further to control the fibres when treating long wool, hair, jute and the like, a preliminary tufting-roller rotating at an intermediate speed may be interposed between the rollers a, a<1>, c, c', and a tube d of glass, brass, or vulcanite may be provided. The roller e may be of ebonite in the case of cotton which is not easily charged electrically, but in the case of wool it is preferably of metal, for example iron, brass or aluminium.

Filed: 1922-12-22
Abstract: 191,378. Westinghouse Electric & Manufacturing Co., (Assignees of Baum, J. V.). Jan. 7, 1922, [Convention date]. Clinkering, preventing ash-pits; grates.-The formation of clinker in a furnace provided with a mechanically-operated grate discharging into a pit is prevented by injecting water into the fuel bed at points high up in the pit. The method is described in connection with an underfeed stoker comprising series of tuyeres 11 or with intervening retorts 12 and a clinker pit 15. Mounted in channels in the sloping faces of air boxes 17, 44 on opposite sides of the pit are distributing headers 24, 48 through which water is discharged into the burning refuse. The header 48 may be omitted where the pit is of comparatively small width. The Specification as open to inspection under Sect. 91 (3) (a) states that steam may be introduced through the headers 24, 48 instead of, or in addition to, water, and that the water may be mixed with air. This subject-matter does not appear in the Specification as accepted.

Title: Electronic musical instrument
IPC: G10H1/043
Filed: 1976-08-23
Abstract: 1520954 Electronic musical instruments NIPPON GAKKI SEIZO KK 23 Aug 1976 [29 Aug 1975] 35004/76 Heading G5J In an electronic musical instrument of the kind in which the tone waveform is stored digitally in a memory and is read out by binary address signals produced successively in an accumulator incremented by numerical values related to the frequency of a depressed key, means is provided whereby during the depression of the key the note sounded is repeatedly changed by octave intervals by shifting the digits of the binary address signal at equal intervals of time. The note may be shifted up by 1-2-3 octaves and then return to the root note directly (Figs. 1(a-c), not shown) or in octave steps (Figs. 1(d-f), not shown). Where several notes are played in succession the second and later notes may be shifted at the same time as the first note (and therefore may start at one or more octaves above the note played) (Fig. 2a, not shown) or the several notes may shift separately (Fig. 2b, not shown). The time interval between shifts may be selected (switch 76, Fig. 6, not shown) according to the time value, (crotchets, quavers, &c.) of the notes being played. The attack-decay envelope is also stored digitally in a memory and read by advancing a counter; to ensure that notes at different octaves are differentiated it is arranged that the envelope counter is reset to zero at each shift so the attack is separated (Fig. 9). The instrument is otherwise similar to that described in U.S.A. Specification 3,882,751.

Abstract: 953,191. Coated transparent films. DAUBERT CHEMICAL CO. Oct. 14, 1960, No. 35340/60. Heading B2E. A corrosion inhibiting transparent heat-sealable sheet comprises a transparent organic film base essentially resistant to the passage therethrough of corrosion inhibiting vapours, a transparent organic covering film bonded to the film base and pervious to the passage therethrough of corrosion inhibiting vapours, and, as a vapour phase corrosion inhibitor compatible with and in operative relation to the cover film, at least one member of the class of straight chain C 6  to C 10  alkanoic acids and C 7  to C 11  aromatic monocarboxylic acids. The alkanoic acids comprise caproic, enanthic, caprylic, pelargonic and capric acids. Typical monocarboxylic acids are benzoic, toluic, and tertiary butyl benzoic acid. The corrosion inhibitor may comprise up to 20% by weight of the covering film and may constitute from 0À1-2 grams per square foot of the heat-sealable sheet. The corrosion inhibitor may be a mixture of benzoic acid and pelargonic acid preferably in the ratio benzoic acid to pelargonic acid of from 3:1 to 1: 3 by weight. The base film may be ethylene glyco1-terephathalic acid polymer, polycarbonates, and the polyester known as "Videne" (Registered Trade Mark). The covering film may be cellulose acetate butyrate, vinyl chloridevinyl acetate copolymer or polyethyl acrylate. The covering film may be bonded to the base film by a transparent adhesive such as butadiene-acrylonitrile copolymer. The sheet may have a thickness of from 0À5-10 mils. As shown, film base 3 passes over coating roller 7 disposed in trough 8 containing an organic solvent solution of the transparent adhesive material and desirably at least a part of the corrosion inhibitor, excess solution being removed by wire bar 9. The organic solvent is evaporated in drying oven 1. The coated film base passes out of the oven and over roller 11, disposed over trough 12, and under sluice 13 through which an organic solvent solution of the cover coating material containing the corrosion inhibitor is applied, the quantity and distribution thereof being controlled by wire bar 14, prior to re-entry of the coated film base into the oven to effect removal of the organic solvent. On leaving the oven the coated film base is cooled by air over a chill roll 16 prior to rolling on windup roll 18.

Abstract: 504,342. Mine-props. ESSEN-BOTTROPER HANDELS-GES. Dec. 5, 1938, No. 35403. Convention date, Sept. 20. [Class 20 (ii)] A telescopic pit-prop, of the kind in which an upper member is supported within a lower member by lateral pressure exerted by a wedge, such as in Specification 411,768, has a sleeve surrounding the upper end of the lower member and a cam fixed to the lower member to restrain the sleeve from downward movement. The upper member 16 is clamped within the upper end of the lower member 10 by means of pressure exerted by laterally movable wedge 13 and block 14, the wedge coacting with an inclined face of a sleeve 12 surrounding the upper end of the lower member, and the block engaging in an aperture 15 in the lower proper member. Welded to the lower prop member on the side opposite to the wedge and block, is an auxiliary downwardly-inclined wedge 11 adapted to coact with an inclined surface on the sleeve, the inclines being such that the parts are just self locking. In order to prevent the sleeve from slipping as the wedge 13 is driven in, a cam 19 is rotatably mounted on a bracket 18 on the lower prop member, so that in one position it prevents downward movement of the sleeve while in other positions it allows such movements for release of the prop. An aperture 22 is provided in the block 14 into which the wedge 13 may engage as the sleeve and wedge are knocked downwardly after the cam has been rotated to the release position, and lips 17 are also provided on the block to prevent it falling into the lower prop member after release.

Title: Improvements in or relating to machinery for the manufacture of cigarettes
IPC: A24C5/47
Filed: 1931-12-23
Abstract: 392,266. Cigarette-making machines. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, and DOLMAN, H. J., Rondray, Church Road, Staple Hill, both in Bristol. Dec. 23, 1931, No. 35520. [Class 130.] Short cigarettes and stub portions are united by an encircling band of cork &c. From a partitioned hopper two cigarettes and an intervening stub fall into aligned pockets in an auxiliary roller 60 from which they are delivered into one of the pockets in the periphery of a main drum 1. Each pocket contains hinged carrier members supported in end bearings and rotated as the drum advances by the engagement of a pinion 19 with a fixed rack 21. A strip of cork &c. supplied with adhesive by a pasting mechanism 78 is severed by a cutter 75 and passes on to the drum where it is retained by suction exerted through passages 32, 33. Both in the auxiliary roller and in the main drum cams formed on the adjacent framing press the cigarette ends against the stubs. As the cork reaches the pocket preceding that in which the cigarettes and stubs are deposited, projections 74 on a drum 73 depress the cork into the base of the pocket. Beyond the point of deposition the engagement of the pinion 19 and rack 21 cause rotation of the carrier, rolling the paper around the cigarette and stub. A heater 71 dries the adhesive as the edges are superposed. Masks 36 interrupt the suction through the passages 32, and after the double cigarette has been cut across by a knife 84, fingers 86 detach the cigarettes which are removed on a belt 87. In a modification the drum may oscillate instead of rotating, the cigarettes and stubs being fed to the middle of the enveloping strip instead of to the end.

Abstract: 473,169. Kinematograph apparatus. SIEMENS & HALSKE AKT.-GES. Dec. 28, 1936, No. 35531. Convention date, Jan. 4. [Class 97 (i)] An intermediate member acts between a claw feed member and a film registering member only so long as is necessary to withdraw the registering member from a perforation and to move the perforation out of register with it ; the registering member moves into the next perforation independently of the feed member. As shown, a claw arm 1, driven by a crank 2 and guided by a pin 3 in an arcuate slot 4, is formed with a lateral projection 5 carrying a claw 6. In the position shown, the claw 6 is about to enter a perforation in the film 17, and the engagement between the projection 5 and a surface 13 on one arm of an intermediate member 11, pivoted at 12, holds the member 11 in a tilted position until the projection 5 slides over the surface 13a and permits the member 11 gradually to resume the position shown. The other arm of the member 11 is offset at its end 11a to extend beneath a bent portion of a registering member 8 carrying a registering pin 8a and mounted on a leaf spring 9 secured at one end 10. The member 11, when tilted, lifts the pin 8a out of the film perforation as the claw 6 enters it, and the spring 9, when the projection 5 has disengaged the member 11, holds the pin 8a in engagement with the film so that it enters the next perforation as soon as the perforation is in position. A sliding shutter 20 may be driven by a crank 21 through a rod 22.
