Title: Improvements relating to the valves of curing bags as used in the curing of hollow articles, e.g., tyre covers and articles composed of stratified material bonded with synthetic resin or the like
IPC: B29C33/76
Filed: 1948-10-12
Abstract: 649,417. Curing-bags for pneumatic tyres ; bags for pressing stratified material bonded with synthetic resin &c. PIRELLI SOC. PER AZIONI. Oct. 12, 1948, No. 26596. Convention date, Oct. 27, 1947. [Class 87 (ii)] [Also in Group VIII] The metal valve through which fluid is forced into the bag is not bonded to the wall of the bag but is inserted into a hole in the bag after the latter has been cured. The valve projects some distance into the interior of the bag and its diameter progressively increases towards the inner end, being in effect, of wedge formation which renders it selfsealing under the pressure of the fluid in the bag. Figs. 2, 3 and 4 show such valves, 1 being the wedge formation, 2 the part which is disposed outside the bag and 7 a stop flange which abuts the outside of the bead of the bag as shown in Fig. 1. Ports G lead from a central bore 4 to the exterior of the valve. The wedge sections shown are of increasing size, the three valves forming a set which are used in turn as the hole in the bag wears during use, the valve of Fig. 2 being used first, then Fig. 3 and finally Fig. 4. Fig. 1 illustrates the making of the bag, a dummy valve D being used during curing, this valve having a cylindrical inner part 1A which forms a cylindrical hole. When the bag has been cured the dummy valve is extracted and the valve of Fig. 2 inserted.

Title: Improvements in electric remote control systems
Inventor: WOODFORD CHARLES GEORGE ALFRED
IPC: G05D3/16
Filed: 1948-10-14
Abstract: 657,070. Electric follow - up systems. ENGLISH ELECTRIC CO., Ltd. Oct. 14, 1948, No. 26727. [Class 40 (i)] In an electric follow-up control system, e.g. of aircraft control surfaces, the controlled member is driven by a pair of power units through a differential gear. Each power unit is controlled from the master controller over a separate control channel and either power unit is rendered ineffective should a fault develop therein or its associated control circuit. As shown, the master controller (not shown) drives the rotors of Magslip transmitters 25, 26, 27. Their respective receivers 19, 20, 21 are driven, with the controlled member 3, through a differential gear 4 by D.C. motors 1, 2 having separately excited fields 5, 6. The receivers 19, 20, 21 are energized from separate A.C. sources 22, 23, 24 and the error signals taken from the transmitter rotors are fed to two-channel amplifiers 28, 29, 30. The outputs from amplifiers 28, 29 energize respective pairs of exciter field coils 15, 16 and 17, 18 which are normally balanced. An error signal upsets the balance whereby the exciters 13, 14 develop voltages of a polarity dependent on the phase sense of the error signal, and energize the respective fields 11, 12 of Ward-Leonard generators 9, 10 feeding the motors 1, 2 which then drive the controlled member to follow up the master controller. The amplifiers which are preferably of the magnetic type may be provided with feed back voltages, for control purposes, derived from tachometer generators 31, 32 driven by the motors 1, 2 respectively, or from intermediate points in the amplification chain. A normally balanced fault localizing relay 37 is energized by polarizing windings 42 by normally balanced voltage coils 40, 41 energized from the tachometer generators 31, 32 and by current coils 38, 39 carrying currents proportional to the armature currents of the motors 1, 2. Normally the motors 1, 2 should be equally loaded. Unbalance of a predetermined amount either of the motor armature currents or their speeds, due to a fault, unbalances the relay 37 to switch the output channels of amplifier 30 either to the energizing coils 43, 44 of polarized self-latching relays 35, 36 or vice versa. The operated disconnecting relay over its contacts A-E disconnects the power supply to the amplifier 28 or 29 and hence to the corresponding motor, cuts-out the other disconnecting relay to prevent accidental disconnection of the second motor, lights the appropriate one of warning lamps 45, 46, releases one or other of contactors 47, 48 to apply dynamic braking to the associ - ated motor and slightly later causes the appropriate one of mechanical brakes 49, 50 to be applied to its motor and lights a lamp 59 or 60 to indicate this has been done.

Title: Improvements in pyrophoric lighters
IPC: F23Q2/46
Filed: 1928-09-18
Abstract: 318,753. Silberknopf, H. Sept. 18, 1928. Pocket igniters, frictional.-In a pocket igniter in which the friction-wheel c is operated by a lever i pivoted to a bracket g rotatable about the shaft f of the wheel, the lever i is disposed tangentially with respect to the wheel so that the free end of the lever has to be subjected to a vertical pressure only in order to operate the wheel. The rotation of the bracket g is limited by extensions h of the support d, the bracket being held in, and returned to the normal position of substantial alignment with the flint holder, by a spring m. The hole in the wheel is preferably larger than the diameter of the shaft f in order to facilitate the operation by the lever i. The operative face of the lever i in engagement with the friction wheel may be convex instead of concave.

Title: Cleaning of magnetic heavy media
IPC: B03B5/44
Filed: 1946-09-07
Abstract: In a method of cleaning magnetic heavy media the medium to be cleaned is subjected to sizing in the damagnetized state and hydraulic classification in the magnetically flocculated condition.  These steps may be performed in any order, but the medium before re-use must be in the demagnetized condition.  The sizing operation may comprise tabling or screening, the former being preferred when the density of the medium is not high, e.g. in coal cleaning, and the hydraulic classifier may be of any known type.  A preferred cleaning process comprises magnetically flocculating the medium, subjecting it to hydraulic classification, e.g. in an upward current classifier, demagnetizing the medium subjecting it to a screening operation, magnetizing the clean medium, subjecting it to thickening, demagnetizing and returning it to the separating system.  The sink and float fractions are treated separately in parallel circuits and the valuable contaminant of the medium is recovered.

Title: Optical logic arrangement
IPC: G02F3/00
Filed: 1965-06-25
Abstract: <PICT:1062545/C4-C5/1> An optical NOR circuit comprises a plurality of input light sources which are reflected into one or more light channels, the arrangement being such that an output light beam is obtained only when there is no light from any of the light sources. In Fig. 1 the beams from input sources L1-L3 are reflected by half-silvered mirrors Sp1-Sp3 on to a semi-conductor wafer H which is opaque to a particular wavelength when illuminated; light of this wavelength from source LZ is selected by a filter F1 and provides the output beam Stz1 when the wafer H is not illuminated from any of the inputs L1-L3.  Apertured screens B1-B3 divide the light into the two channels, and the mirror Sp2 may be provided with an etched spot C which defines the output beam Stz1 and which provides an output beam St21 whenever there is an input from L2.  In a modification, Fig. 3 (not shown), the light source L2 and semi-conductor wafer H are omitted, and the input light sources are directed on to a light detector (E) controlling a light source (S) which provides the output light beam Stz1.  The units E and S may comprise a resistive photo-cell and neon lamp, or a photo transistor and Ga As Lamp.  In another arrangement, Fig. 2 (not shown), input light beams (St4 and St5) are respectively reflected into a glass rod (Gs) forming the light channel by means of a set of shallow etched-out areas (Ae) and by means of a single groove (Ek) acting like a prism.  The output beam may be split into two outputs by using a half-silvered mirror (Sp4, Fig. 4, not shown).

Title: Improvements in or relating to vehicle rear viewing mirrors
IPC: B60R1/076
Filed: 1955-11-25
Abstract: 854,885. Rear-viewing mirrors for vehicles. O'SHEI, W. E. Nov. 26, 1956 [Nov. 25, 1955], No. 27069/60. Divided out of 854,884. Class 103(2). [Also in Group XXV] A rear-viewing mirror comprises a stanchion 2, Fig. 1, rotatable about a base member 24 constituting part of or adapted to be secured to a vehicle body by a rotatable joint comprising the abutting surfaces at the foot 22 of the stanchion and at a recess 24a in the member 24. The surfaces are retained together by a leaf spring 28 secured at one end to the foot and at the other to a pin 30 which bridges a bore at a stem 24b of the member 24, the spring being located on the pin by collars 29 and being downwardly urged by a coil spring 29a in the stem. The parts of the joint are normally retained in a predetermined position about the axis of rotation by indexing means comprising fingers, plungers or balls 10 located in cavities 24c in the base member and outwardly urged by springs 11 to engage complementary recesses 22b in the lower face of the foot of the stanchion. An adjustable connection 3 on the stanchion supports the mirror element 1 and the leaf spring twists under a displacing force to allow the stanchion to turn relative to the base part, the resultant shortening of the spring producing a torsional force to restore the stanchion to its original indexed position. In a modification, a rubber bush 58, Fig. 2, bonded on its inner and outer surfaces to metal rings 58a, 58b, is mounted within the stem of the base 54 and has flats (not shown) on the outer ring to engage corresponding flats within the bore to prevent relative station therebetween and similar flats on the inner surface of the inner ring engage corresponding flats on the stem 52b of the stanchion which projects into the bore. The lower end 52a of the stanchion rotatably fits within a circular recess 54a in the base part 54 so that turning of the stanchion relative to the base part applies torsion to the rubber bush which tends to return the parts to the initial indexed position. The indexing means comprise fingers, plungers or balls 10 in cavities 52c provided in the lower end 52a which are urged by springs 11 into engagement with corresponding recesses 54c in the base part. The stanchion may be constructed of closely wound helical spring 52d as described in Specification 848,073. Specifications 746,370 and 775,594 also are referred to.

Abstract: 463,634. Percussive drills. TUCEK, K. Oct. 1, 1935, No. 27111. Convention date, Oct. 4, 1934. [Class 124] The hollow piston 6 of the internal-combustion percussive tool is double acting and contains a spring mounted tup. The combustible mixture for each stroke is compressed by the piston 7 on its downward stroke and passed to the cylinder A through the grooves 50, and to the cylinder B through passage 14 and grooves 51. The upper surface of the piston 7 forces cooling air down the hollow piston rod 6a and also through valves 55 to cool the cylinder 2. The steel 28 is struck by the tup 52, the spring 53 of which allows the piston 6 to complete its full stroke irrespective of the position of the steel. The tool is started bv movement of the handle 20, the lower end of which engages the inside of the tube 6a when the wedge rod 58 is forced downwards.

Title: Improvements in or relating to textile dressings
IPC: E05B37/00
Filed: 1936-10-08
Abstract: A textile dressing especially suitable for knitting yarns consists substantially of a polyhydric alcohol and 2-8 per cent by weight thereof of a salt or soap of an alkylolamine with a higher fatty acid.  The dressings are particularly suitable for cellulose acetate yarns, overcoming electrification difficulties. Suitable alkylolamine soaps are those of capric, lauric, myristic, oleic, stearic or palmitic acid with mono-, di- or tri-ethanolamine, a propanolamine or N-phenyl ethanolamine. Suitable polyhydric alcohols are glycerin, glycol, ethylene glycol or diethylene glycol and these may be employed with water in an amount to bring them into equilibrium with the atmosphere.  The compositions may contain small amounts of lubricants, e.g. vegetable and animal oils and wetting agents, e.g. sulphonated oils or alcohols.  They may be applied by wicks, rollers, rotating discs, or as a bath treatment.  Warps can be dressed on a slasher and fabrics, e.g. pile fabrics by padding.  A suitable amount of dressing is 1--5 per cent of the yarn.  The dressings may be applied instead of or as well as usual lubricants such as olive oil, e.g. to artificial filaments at the time of their formation. Specifications 376,785, 388,769, 433,110; and 450,420, [Group III], are referred to.ALSO:A textile dressing especially suitable for knitting yarns consists substantially of a polyhydric alcohol and 2--8 per cent by weight thereof of a salt or soap of an alkylolamine with a higher fatty acid.

Abstract: 1,201,685. Automatic firearms. FABRIQUE NATIONALE D'ARMES DE GUERRE. 12 June, 1968 [7 July, 1967], No. 27890/68. Heading F3C. An automatic firearm comprises a hammer having an extension with stops engaging, in the cocked position, hooks provided on pivoted catches of a trigger mechanism (Fig. 1, not shown). A device for limiting the number of shots in a burst is provided and includes a first rocking lever 15 which, by means of an arm 17 pivoting under the action of a fire control mechanism, is brought into an operative position in which, during firing, projections at its forward extremity co-operate one by one with a finger (Fig. 1, not shown) mounted on the hammer. At each shot the lever 15 is further pivoted against a return spring 18, the rearward end of the lever 15 having projections which engage one by one with a lug on one of the catches, the lug therefore being kept out of engagement with the hammer. During the penultimate shot the lever 15 engages a lower shoulder 16b of a second lever 16 to urge a segment 16c thereof in front of the lug of the one of the catches to hold the lug, the last projection of the rear end of lever 15 being disengaged from the lug and at the same time the projections on its forward extremity move away from the action of the finger. The lever 15 thus rotates under the action of its return spring 18 and in its travel entrains the lever 16 through a shoulder 16a thereof to disengage the lug and so end the burst. The number of shots in a burst depend on the number of projections on the forward and rearward ends of the lever. The finger may be spring loaded and the burst control device may be housed in a casing 11 held in the firearm by the axle of the hammer cooperating in a fork 12a and the pivot of the fire control mechanism which passes through an aperture 12b in the casing.
