Title: Band pass filter for electrical or electronic musical instruments
IPC: G10H1/06
Filed: 1971-07-22
Abstract: 1350159 Filters KEIO GIKEN KOGIYO KK 22 July 1971 [30 July 1970] 34365/71 Heading H3U [Also in Division G5] A band pass filter, intended for use in electronic musical instruments, comprises high pass and low pass filter sections, each section having means for adjusting its cut-off frequency, the adjusting means being controlled by knobs slidably mounted on guide means arranged so that the band pass characteristic is never lost. In the Figure, a tone generator circuit for a musical instrument comprises an electronic signal source 1 and high and low pass filters 2, 4 respectively. Low pass filter 4 may be fed by a buffer amplifier 3 and a main amplifier 5 feeds a loud-speaker 6. High-pass filter 2 comprises capacitors C 1  to C n  which can be switched into circuit by means of contacts S 1  to S n  and movable contact S 0 . Inductance 8 completes the high pass filter. Movement of knob D along rod 11 therefore controls the number of capacitors inserted in filter 2 and hence its cutoff frequency. Similarly, knob D<SP>1</SP> controls the cut-off frequency of low pass filter 4. When the knobs are held together the high and low pass filters are designed so that the high pass filter has a cut-off frequency below that of the low pass filter. The filters therefore constitute a band-pass filter and because the knobs cannot cross the band-pass characteristic is never lost i.e. the cut-off frequency of the high pass filter cannot rise above that of the low pass filter. As movement of the knobs varies the cut-off frequencies of the filters the pass band width and position can be changed at will providing the band-pass characteristic of various instruments. A vibrato effect can be obtained, by slightly moving only one knob, e.g. D, to right and left. A further embodiment (Fig. 2, not shown) utilizes two separate rods with a knob mounted on each.

Title: Apparatus for forming plugs of filler tobacco for cigar bunches
IPC: A24C1/02
Filed: 1961-09-27
Abstract: 952,229. Cigar-making machines. KONINKLIJKE VEREENIGDE TABAKSINDUSTRIEEN MIGNOT & DE BLOCK N.V. Sept. 27, 1961 [Sept. 29, 1960], No. 34724/61. Heading A2C. A machine for manufacturing cigar fillers has a chamber 1 in which tobacco is compressed by a plunger 2, the extent of travel of the plunger controlling mechanism which determines the amount of tobacco delivered to the chamber. The plug is mounted on a rod 4 slidingly mounted on a driving block 5 which is reciprocated by a cam and lever arrangement. When the block 5 moves to the left to cause compression of the tobacco a pawl 33, operated by a further cam and lever arrangement, frees a cam member 29, an arm 28 of which is acted upon by a roller 31 on the end of rod 4. The cam 29 is mounted on the block 5 so that the slope of the cam is determined by the extent to which the rod 4 moves with the block 5. The pawl 33 then locks the cam 29 in position and as the block 5 is moved to the right the cam acts on a lever 25, movement of which operates through a link 22, a conveyer 13 to deliver tobacco down a shoot 15 to the chamber 1. The amount of tobacco delivered depends on the extent of movement of the lever 25, which in turn depends upon the setting of the cam 29. A member 17 is arranged to close the shoot 15 during the operative stroke of the plunger 2.

Soaps; fatty acids; lubricants for machinery.- A modified acid is obtained by treating oleic acid with alkaline hypochlorite or hypobromite, and decomposing the product with acid. This modified acid is treated alone or in admixture with organic substances with a further quantity of hypochlorite or hypobromite to obtain liquids or thick pastes which are completely soluble in water. The pastes may be dried without loss of solubility. Organic substances which may be used are hydrocarbons such as petrol, kerosene, petroleum, solar oil, pale oil, petrolatum oils, paraffin, benzol, toluene, xylene, cumene, cymene, coal oils, naphthalene, alkylnaphthalenes, terebene, limonene, pinene, phellandrene, oil of camphor, or resin oil, chlorinated hydrocarbons such as carbon tetrachloride, chloroform, di-, tri-, tetra-, or penta-chlorethane, or chlorethylene, chlorbenzene, o- or p-dichlorbenzene, esters such as benzyl acetate, amyl acetate, or amyl salicylate, essential oils such as essences of lemon, orange, citron, aniseed, clove, or mint, animal or vegetable oils, fats, or waxes, as olive oil, fish oil, whale oil, tallow, beef or mutton fat, and castor oil, and alcohols, phenols, and cyclohexanols, as methyl, ethyl, propyl, butyl, or amyl alcohols, normal, secondary or tertiary, benzyl alcohol, cinnamic alcohol, cyclohexanol, methyl- or di-methylcyclohexanol, phenols, cresols, xylenols, ethyl, propyl, butyl, or amyl phenols or cresols, terpineol, geraniol, and linalol. The liquid products are used to dissolve essential oils and render them soluble in water or dilute alcohol. The modified fatty acid, or any of the above preparations, are employed for domestic purposes, in the treatment of textile fibres or fabrics, for lubrication of machinery, and washing of painted or varnished or other coated surfaces.

Title: Improvements in and relating to nuclear reactor plants
IPC: G21D3/08
Filed: 1965-08-13
Abstract: 1,114,652. Nuclear power plant. SULZER BROTHERS Ltd. 13 Aug., 1965 [13 Aug., 1964], No. 34814/65. Heading G6C. In a nuclear power plant, steam is generated in a heat exchanger and is supplied to a turbine. The working fluid, which may be at the thermodynamic supercritical state, flows through the exchanger along two parallel paths. The flow in each path is separately controlled by valves which are automatically adjusted in accordance with the working fluid temperature and the reactor coolant temperature and rate of flow. The temperature distribution in the heat. exchanger at any load is such as to restrict the maximum temperatures for the working medium and reactor coolant to a small section of the heat exchanger. The heat output of the reactor and therefore the plant load is measured by the pressure drop across an orifice in the coolant circuit, as the coolant rate of flow is a function of the reactor heat output being automatically controlled in accordance with coolant temperature. In one embodiment, the relative rates of flow of working fluid through the two exchanger paths are predetermined by cam-operated valves while in the second arrangement, the relative flow distribution is varied in accordance with exchanger temperature.

Title: Improvements in or relating to Overload Releases for Conveyor Drives and the like
IPC: B65G43/06

Abstract: 1,196,294. Conveyer drive means. MECHANICAL HANDLING SYSTEMS Inc. 1 Aug., 1967 [1 Aug., 1966], No. 35264/67. Heading B8A. [Also in Division F2] An overload device in the drive for a conveyer chain 11 comprises a drive member 13 rigidly mounted to a drive shaft 12 and pivotally mounting at 24 a pair of latches each having a recess 25 for engagement with a corresponding roller 26 mounted on a driven member 18 freely rotatable about said drive shaft 12. The free end of the latches 23 pivotally mount a cam follower 35 for engagement with indents 33, 34 in an arm 29 attached to the drive member 15. The cam follower is urged by a spring 39 into engagement with the indent 33 to urge the recess 25 into contact with the roller 26 and thereby drive the driven member 18. When the chain 11 is overloaded, however, and the drive member 13 continues to rotate, the latch 23 is forceably raised against the action of the spring until the cam follower engages indent 34 and the drive to said driven member 18 is broken. The latch is reset by merely pushing each latch inwardly at 23a. The tension of the spring 39 and thus the break-out strain is adjustable by means of a screw 42 and lock nut 43. In an alternative embodiment (Figs. 6 and 8, not shown) each latch (58) comprises a pair of spaced arms (59), (60) with a roller (61) therebetween for engagement with pockets (62) in the driven member (63). The free end of the latch mounts a cam follower (69) for engagement with an indent (71) in one arm (68) of a pivotally mounted bell crank (66). The other arm (67) is engaged by a spring (72) to provide the break-out force for the overload mechanism. The said mechanism may be reset by pulling outwardly on said arm (67). Alternatively a tapered pin (81) mounted on a reset ring (82) is movable axially by a solenoid (83) to engage a cam surface (80) on the latch (58) to reset the same and re-establish the driving connection.
