Title: Producing shaped articles from re-inforced organopolysiloxane elastomers
Inventor: AMES JACK
IPC: C08L83/04
Filed: 1960-08-12
Abstract: A coating for continuous filaments of, e.g. glass, metal, asbestos, nylon or polyester comprises an organopolysiloxane elastomer, which may include 20 to 50 parts by weight per 100 parts of the elastomer of a filler, e.g. fume or precipitated silicas, and silica aerogels. The elastomer contains saturated or unsaturated hydrocarbon radicals and may comprise 100 parts of a diorganopolysiloxane having from 1,98 to 2,01 organo groups per silicon atom, 4 to 20 parts by weight of a linear organopolysiloxane having from 0,98 to 2,0 organo groups per silicon atom, 0 to 70 parts of a reinforcing filler, 0,5 to 10 parts of a curing agent and 0 to 10 parts of a structure control additive. The organo groups may be alkyl groups such as methyl or ethyl groups, aryl groups such as phenyl or tolyl groups or unsaturated groups such as allyl or vinyl groups.  The linear organopolysiloxane may contain alkyl groups such as methyl or ethyl groups, aryl groups such as phenyl groups or unsaturated groups such as vinyl groups.  The curing agent may be an organic peroxide, used in amounts up to 10% by weight of the composition, e.g. benzoyl, 2:4-dichlorobenzoyl, dicumyl or ditert-butyl peroxide or tert-butyl peracetate.  Two peroxides may be used, e.g. 2:4-dichlorobenzoyl and dicumyl peroxides, in amounts from 0,25 to 2,0 parts each by weight per 100 parts of organopolysiloxane. In an example an elastomer composition is made up by compounding 90 parts of methylvinylpolysiloxane containing 0,1 mol. per cent vinyl groups, 10 parts of a methylhydrogenpolysiloxane, 40 parts of finely divided silica coated with 20% of its weight of octamethylotetrasiloxane, 5 parts of red oxide, 1 part of (tetramethylethylenedioxy) dimethylsilane, 3 parts of a 50% suspension of 2:4-dichlorobenzoyl peroxide in a polysiloxane fluid and 3 parts of a 40% dispersion of dicumyl peroxide on calcium carbonate.  The Specification includes a further example describing an organopolysiloxane composition.ALSO:Continuous filaments of e.g. glass, metal, asbestos, nylon or polyester are coated, e.g. by extrusion, with an organopolysiloxane elastomer, which may include a filler, e.g. fume or precipitated silicas, and silica aerogels, shaped, and finally cured under heat and pressure.  The filaments may be shaped by (a) passing through a die, (b) helically wrapping them around a collapsible metal former and then winding wet tape of cotton, nylon or polyethylene terephthalate around the filaments and heating to cause the tape to apply pressure by shrinking or (c) cutting the filaments into short lengths, placing them in a mould and applying heat and pressure.  The tube made by process (b) may be internally or externally reinforced with glass cloth which may be previously coated with an organopolysiloxane composition.  Process (b) may be used to form spiral heating elements.

Title: Improvements in volume control in radio receivers
IPC: H03G3/22
Filed: 1933-10-12
Abstract: 426,803. Valve circuits for wireless reception. MURPHY RADIO, Ltd., and MOXON, L. A., 62, Brook Street, Hanover Square, London. Oct. 12, 1933, No. 28213. [Class 40 (v)] For automatic volume control a varying master bias voltage is arranged to vary the bias of each controlled valve only between definite limits both independently determinable for each valve. As shown, three intermediate frequency amplifiers 1, 2, 3 with tuned grid circuits 4, 5, 6 respectively feed the tuned input circuit 7 feeding the diode rectifier 8 of a double diode triode valve 12. The rectified D.C. potential developed across the load resistance 9 is applied through a resistance 11 to the grid of the triode portion of valve 12. Delayed amplified A.V.C. potentials are derived from the point 25 as follows. Connected across the H.T. supply are two parallel circuits one comprising the triode 12 and resistance 14 and the other the resistance 13, which may be that of the rest of the receiver, and a resistance 15, which may be a loud-speaker field winding. Connected in series between the points 20 and 21 which are the intermediate points of the above-mentioned circuits, are a resistance 24 and diode 23. As the potential of the point 21 falls relative to the point 20 owing to the change in impedance of the triode 12 due to a rectified signal voltage on its grid a point is reached at which the diode 23 becomes conducting and the point 25 thereafter follows the potential of the point 21. The master bias thus produced is distributed to the valves 1, 2, 3 as follows. The grid of valve 3 is connected to the point 25 through a resistance 26, that of valve 2 through a resistance 31 and rectifier 28 and that of valve 1 through rectifiers 33, 28. The cathodes of valves 1, 2, 3 are connected to points 20, 30, 35 respectively of suitable potential, on the resistance 15. The point 30 is also connected through a rectifier 27 to the resistance 26 and through a resistance 29 to the rectifier 28 while the point 35 is also connected through a rectifier 32 to the resistance 31 and a resistance 34 to the rectifier 33. When no signals are being received none of the resistances 24, 26, 29, 31, 34 is carrying current and all the grids are at cathode potential. As the point 25 becomes more negative, after a certain signal strength is exceeded, the grid of valve 3 is affected through resistance 26 until the rectifiers 27, 28 pass current. The grid of valve 3 is then connected to the point 30 and the potential of the point 25 reaches the grid of valve 2 through resistance 31. As the point 25 becomes increasingly negative the rectifiers 32, 33 pass current, the grid of valve 2 attains the potential of the point 35 and the potential of the point 25 is communicated to the grid of valve 1. By returning the parallel branches such as 26, 27 and 28, 29 to points of different potential, the control of one valve may be caused to begin before or after the cessation of the control of the valve previously controlled. Specification 407,317 is referred to.

Abstract: 915,824. Packaging-machines. HESSER, MASCHINENFABRIK A.G., FR. Aug. 4, 1961 [Aug. 8, 1960; Aug. 17, 1960], No. 28352/61. Class 94(1). Apparatus for discharging weighed quantities of pourable material into packaging containers P comprises fixed weighers 2, a conveyer 1 for transporting containers to a filling zone, transfer receptacles 7 movable with the conveyer over part of its travel, and shoots 4 which are swingable about pivots 5 whereby material is discharged through the shoots into the containers. The receptacles 7 are arranged to be reciprocated and are filled from the weighers when moving in the opposite sense to the containers and discharge into the containers when moving with them in the same sense. Each weigher 2 is made up of two separate component weighers with their discharge nozzles 3 opening into one shoot 4. The receptacles 7 are mounted on a rail 8 from which a slotted arm 35 depends and a roller 34 is guided in the slot and projects from an endless chain 33, resulting in reciprocation of the rail 8 and thus of the receptacles 7. Slotted arms 30 rise from the rail 8 and engage pins 31 on the shoots 4, to which the reciprocations of the rail 8 are thereby transmitted The rail 8 is also reciprocated vertically by imparting the required movement to its guideway 9, which is pivoted to bell cranks. 61, connected by a link 62, and one of the bell cranks is oscillated from a cam 64 through linkage 65, 67. Each receptacle 7 has pivoted flaps 10, 11 at its base, normally closed by springs 73, and as the rail 8 descends, levers 70, 71 connected to the flaps bear against a rail 12 and open the flaps for the contents of the receptacles 7 to be discharged into a container P. In a modification the receptacles 7 are secured to a conveyer chain which runs above the conveyer 1, and the weighers 2 first empty into the receptacles 7, which then traverse a return section of the conveyer and come into register with containers P into which they then discharge. Alternatively the conveyer chain on which the receptacles 7 are mounted may be at one side so that only one of its straight sections is above the conveyer 1. In the latter two embodiments the closure flaps 10, 11 are as shown in Fig. 11 and are operated by a cam rail 12a In a simpler arrangement the closure flaps may be dispensed with and the weighers may discharge through the shoots 4 and receptacles 7 directly into the containers P. Specification 878,963 is referred to.

Filed: 1928-10-05
Abstract: 307,417. Electrical Research Products, Inc., (Assignees of Cousins, V. M.). March 7, 1928, [Convention date]. Thermionic amplifiers.-In order to eliminate hum in a mains-fed thermionic amplifier the grid is connected to one end of the filament supply transformer and the anode is connected to a tapping on a resistance inserted in series with the other end of the supply transformer. Disturbing components are thereby applied to the grid and plate in phase opposition 20 so as to balance out. The Figure shows the system applied to an electric gramophone installation. The filaments of the amplifiers 12, 15 are fed from the secondary winding 26, and that of the amplifier 18 from a separate secondary 27, both being energized from an alternating source 23. The plate supply for all valves is taken from a battery 30. Any hum component present in the filament supply will reach the grid at the common point of connection. In the opposite branch of the filament circuit is the series resistance 41, in which the same disturbance is present but in opposite phase. This component will reach the plate via a tapping 41 adjusted so that the amplification factor of the valve is taken into account. A similar resistance 42 and tapping 43 neutralizes hum in the power valve 18. Chokes 37, 35 and condensers 38, 43 prevent backcoupling through the common resistance of the battery 30. A modified arrangement suitable for a public-address installation is also described in which the last stage of amplification consists of two valves in push-pull. Rectified plate current is derived from the source supplying the filaments with alternating current, and gridbiasing voltages are obtained from resistances inserted in the rectified plate supply.

[Classes 100 (i) and 100 (ii).] Hectograph copying-apparatus; sheet-delivery apparatus ; sheet feed-tables, guides, registering- devices, and forwarders.-In a hectograph copying-machine of the type comprising a stationary segmental bedplate supporting a gelatine band and in which paper sheets are pressed into engagement with the band by a roller travelling in a circular path over the bedplate, mechanism is provided for stripping the sheets from the gelatine band after printing. Mechanisms for advancing and tightening the band and for feeding sheets are described also. The machine shown comprises a gelatine band 38 stretched over a felt pad supported by a curved plate 36. The band 38 is mounted on spindles 42 each of which is adapted to be rotated by a hand-crank and is provided with a brake band operated by a lever connected by a spring to a disc such that by turning the disc from the position where both spindles are released one of the spindles is clamped before the other, whereby the latter may be rotated to tighten the band before being locked in position. A pile of sheets is laid on a table comprising a horizontal portion 43 and an inclined portion 44, the front edges of the sheets abutting against an inclined stop 45. The top sheet is pushed forward by hand over a rotary roller 55 and under a comb 48 carried by a rod 49 rotatably mounted in bearings on a member 51 adjustable about a pivot 52, and the sheet is fed forward under the rod 49 and up to a stop 58 by a rotary disc 56 provided with a raised feed surface 57. Where two sheets are to be fed side by side, two discs 56 suitably spaced apart are provided. The sheet forms into a loop as shown and the front edge engages a groove in the stop, after which an impression roller 60 carried by spring- pressed arms 61, mounted on rotary wheels 32 presses the sheet on to the band 38. Stripping- rollers 67, 68 supported also by the wheels 32, follow behind the roller 60 and remove the printed sheet. The rollers 67, 68 are mounted in brackets 69 and are rotated by a stationary gear 76. When opposite the stop 58 the brackets are tilted about the axis of the roller 68 against the action of a spring 83, by stationary cams carried by arms 85 so that the roller 67 clears the edge of the sheet. At the same time, the stop 58, which is pivoted to the arms 85 and is integral with an arm 86 engaged by a cam-actuated lever 89, is moved outwardly so that the edge of the sheet springs into the bite of the rollers 67, 68. The sheet is gradually stripped off and is directed by fingers 97 on to a series of elastic bands 99 looped at one end over a rod 101 carried by the wheels 32 and hooked over a rod 102 at the other end ; rods 100 support the bands in intermediate positions.
