Title: Improvements in or relating to methods of capping bottles and apparatus therefor
IPC: B67B3/02
Filed: 1937-05-28
Abstract: 496,249. Bottle capping machines. GAMMETER, J. R. May 28,1937, No. 14903. Convention date, June 3, 1936. [Classes 125 (ii) and 125 (iii)] A bottle-capping machine for applying elastic or yieldable caps such as those described in Specification 451,465, having a substantially flat top portion and an integral skirt portion normally extending in substantial parallelism with the top portion and provided with an axial opening, to uncapped bottles &c., has in addition to the fingers 24 for opening the caps 38 a pipe 77 through which air is passed to inflate the caps before application. The fingers 24 depend from a sleeve 23 mounted on the carrying tube 13, their lower ends being upwardly turned to enter the lower part of a magazine 33 containing a pile of caps, the magazine being removably inserted in the tube 13. The lower end of this tube is provided with a collar 18 serving as a cam surface for controlling the movement of the fingers and also a slotted collar 19 for separating the latter; the fingers are held in place by a spring 27 &c. The sleeve 23 is actuated manually by a handle 55, being connected by a link 57 to the crank pin 54 to which the handle is secured ; the handle by its movement rotates a member 47 which has on its rear face a cam groove 50 engaging a roller 51 of a sleeve 30 on which the magazine adjustably and removably rests, so reciprocating the latter. Joint movement of the magazine and of the fingers facilitates the entry of the latter into the lowermost cap and assists in the movement of distention. The magazine is formed with a slot 44 extending down its side to facilitate changing, and it is provided with a removable cap 34. The air pipe 77 is carried by a pivoted member 78, the trunnion of which is hollow being in communication on the one hand through a passage 66 with the interior of the pillar 11, itself supplied with air from a blower 91 and a heater 92, and on the other hand through an opening 74 with the pipe 77 when this is brought into its operative position. Actuation of the pipe is effected as follows : upward movement of the sleeve 23 causes a projection 86 thereon to engage a lever 84 connected by a vertical link 80 with a projecting arm 76 on the member 78 carrying the tube 77 ; so raising the pipe to its operative position with its mouth opposite to the magazine ; further upward movement of the sleeve 23 while depressing the outer end of the lever 84 serves only to compress a spring 89, the upper end of the link 80 being slotted to permit this. On lowering of the sleeve 23, the lower ends of the fingers are spread apart so permitting the mouth of the bottle to enter the distended cap, and at the same time the pipe 77 is moved to the side out of the way of the bottle. When the capsules are made from a rubber hydrohalide, heating by means of a hot air blast is desirable in order to render the material sufficiently pliable. Specification 451,464 also is referred to.

Title: Improvements in or relating to power transmission mechanism
IPC: F16D33/02
Filed: 1930-05-15
Abstract: 361,281. Power transmission for motor vehicles. SALERNI, P. M., 23, Carlton House Terrace, London. May 15, 1930, No. 15024. [Class 79 (ii).] The power transmission of a vehicle comprises an hydraulic transmitter B, Fig. 1, between the engine A and the changespeed gear C of " positive " type. This is the type in which power is transmitted through solid material under shear, bend, or compression loads without possibility of slip, and adapted for easy changing without disconnecting the hydraulic drive by the provision of interrupting- means in the transmission. Gears of this type are described in Specifications 347,093 and 347,165,' [both in Group XXIVWith this type of gearing, when the drive has been interrupted in speed changing, it remains interrupted until due to acceleration or deceleration of the engine end relatively to the road wheels end of the transmission, automatic reconnection is effected when synchronism has been attained. The interrupter may be at any suitable point. The change-speed gear C may be controlled by hydraulic means as described in Specification 351,505, [Group XXIV]. The hydraulic transmitter is of the type comprising a driving vane wheel B<1> and a turbine or driven vane wheel B<3>. These wheels are secured to the engine shaft A<1> and to the driving-shaft B<4> of the change gearing respectively. For changing during racing, the shaft B<4> may be fitted with a drum E adapted to be engaged by a brake El applied by a pedal E<2> to reduce the speed of that shaft. The transmitter B may be controlled by moving axially a ring valve F, Fig. 2. This may be done manually, or automatically by centrifugal weights F<2> acting against a central spring F3. Specifications 353,108 and 353,334 also are referred to.

Title: Improvements in primary electric cell
IPC: H01M4/62
Filed: 1943-09-13
Abstract: 579,849. Batteries. MALLORY & CO., Inc., P. R. Sept. 13, 1943, No. 15028. Convention date, Aug. 26, 1942. [Class 53] A primary cell, for use in low temperatures, comprises a zinc or cadmium electrode, a depolarizing electrode comprising a metal sheet with a conducting depolarizing composition such as copper oxide adhering to it, a semipermeable membrane such as " Cellophane " (Registered Trade Mark) separating the two electrodes, and an alkaline electrolyte, such as the hydrate of potassium, sodium, or lithium. The membrane may be spaced from one or both electrodes (a) by an intermediate fibrous layer of nylon, glass fabric &c. or (b) by corrugating or embossing one of the electrodes. Fig. 1 shows a cell comprising coiled sheet materials including a zinc foil electrode 12, two layers 17, 18 of nylon, two layers 15, 16 of regenerated cellulose, and a steel electrode 14 coated with cupric oxide, graphite, and a binder, such as a solution of polymerized vinyl chloride. The coated steel strip is rolled under pressure at a temperature of 125C. An additional coating of pure graphite and binder may be sprayed on to the cupric oxide-graphite layer. In place of cupric oxide, sulphides of copper or lead, or lead oxides may be used. The electrolyte is absorbed by the layers 15, 16, 17, 18. In Fig. 4, cellulose sheets 15, 16 engage each side of the zinc foil 12, and the coated steel electrode 28 is corrugated. The coiled electrodes &c. held in rolled form by a rubber band may be supported in a steel can 21, Fig. 2, filled with electrolyte, and provided with a shoulder on which rests a closing disc 23 through which projects the threaded portion of a zinc rod 11 connected to the zinc foil 12. The rim of the can is spun over a rubber ring 24 to seal the can. In a modification, Fig. 3 (not shown), a disc of dry potassium hydrate is placed at the bottom of the can, and the cell activated when required by adding water. The electrolyte preferably contains at least 33 per cent. of potassium hydrate. The strips of fibre may be impregnated with electrolyte before coiling, the use of a cloth spacer or a corrugated electrode being then unnecessary.

Title: Gas turbine plants
IPC: F02C7/12
Filed: 1971-05-14
Abstract: 1347514 Cooling gas turbine plants SOC RATEAU 14 May 1971 [19 May 1970] 15052/71 Heading F1G In a gas turbine plant having a compressor 6b supplying air to a combustion chamber 15b feeding hot gases to drive a turbine 7b, at least some of the compressed air is fed directly from a sector of the compressor discharge and through a duct 29, substantially without change in temperature and velocity, to a sector of the turbine inlet so that the turbine rotor blades alternately pass through regions of hot gases and cooling air. In the arrangement shown the compressor 6b is centrifugal and feeds a major proportion of its air output via a sector of guide blades 26b and scroll 136 to combustion chamber 15b, the remaining proportion flowing through unbladed sector 29 defined between partitions 27, 28 directly to the corresponding unbladed sector at the inlet to centripetal turbine 7b integral with compressor 6b. More than one direct flow sector may be provided. The annular discharge conduit 21b from turbine 7b is interrupted at its inlet by two partitions (31 and 32), Fig. 3a, (not shown), defining a duct 33 through which the cooling air leaving turbine 7b discharges at 34 to atmosphere. A power turbine 23b is provided. In a modification Fig. 6, (not shown), cooling air duct 29 is supplemented or replaced by extending the radial flow compressor and turbine blades radially beyond the hub (43) to provide an annular space (44) into which a stationary part-annular partition (45) extends. The gap between the ends of the partition provides a duct for the direct flow of cooling air from the compressor to the turbine. In further modifications, Figs. 8 and 9, (not shown) an additional turbine driven axial flow or centrifugal compressor (47) is provided upstream of compressor 6b and the cooling air leaving the turbine is returned to the second stage compressor via a cooler (52). The compressed air may be pre-heated in an exhaust gas heat exchanger (53) before entering the combustion chamber. The radial flow turbine and compressor may be replaced by axial-flow Fig. 7, (not shown).

Title: Improvements in or relating to Over-load Electric Switches or Cut-outs.
Inventor: WIJK PIETER GERRIT VAN
IPC: H01H71/44
Filed: 1916-10-23
Abstract: 107,365. Wijk, P. G. van. June 15, 1916, [Convention date]. Automatic circuit-breakers &c.-In an overload switch or cut-out, an electro-magnet 41 energized by the main current causes, on the occurrence of an overload, the excitation of a second electro-magnet 17 which operates in conjunction with an escapement 23, 24 to open the main switch 1 should the overioad persist for a sufficient interval of time; if the overload is of short duration, the mechanism is automatically returned by a balance weight 36 or spring &c. The switch 1 is locked in the closed position by a member 2 projecting in front of a cross-bar 3; the upper end of the member 2 has a roller 6 which is forced by a spring 5 against the periphery of a disk 8 secured to a spindle 7 mounted in plates 9, 10 of the frame. The end 12 of a lever 11 mounted on the spindle 7 is held by the hooked portion 14 of a pivoted pawl 13 against the action of a spring 15. When the hook 14 is lifted owing to the downward movement of a link 32, the lever 11 swings out and causes rotation of the disk 8, allowing the roller R to enter a recess 16 in the disk and release the main switch 1. The movement of the link 32 is brought about by the excitation of the electromagnet 17, the core 18 of which rotates a spindle 22 by means of a cord 19 &c. The ratchet-wheel 23 of an escapement is loosely mounted on the spindle 22, the anchor 24 being fixed on a spindle 25 which carries also a pendulum with an adjustable weight 27. The wheel 23 is coupled to the shaft 22 by means of a one-way clutch comprising a pawl 39 and a toothed wheel 40. The rotation of the spindle 22 is transmitted to a toothed wheel 29 having a pin 31 engaging the link 32. The mechanism is designed so that the lever 11 is only released when the core 18 reaches the end position of its attraction; a balance weight 36 or a spring acting upon the shaft 22 in opposition to the rore 18 causes return of the latter to its upper position when the overload is of too short a duration; the wheel 23 does not turn with the shaft 22 during the reverse movement. As shown, the coils of the magnets 17, 41 are joined in series and the magnet 17 is normally shortcircuited across the contacts 45, 46; on an overload, the contact-bridge 44 is withdrawn and the short-circuit broken. Alternatively, the coils of the magnets 17, 41 may be connected in parallel. the magnet 41 then closing the circuit containing the magnet 17. The core 43 has a pin 48 guided in slots provided in stops 49.

Title: Improvements in the treatment of acrylic fibre fabrics
IPC: D06M13/256
Filed: 1963-04-17
Abstract: The formation of pills on the surface of fabrics made from acrylic fibres is prevented by treating the fabrics with an emulsion or an aqueous solution of an antistatic agent which is a water insoluble synthetic resin containing epoxide groups prepared by reacting a water insoluble polyamine containing polyalkylene oxide residues having more than one reactive hydrogen atom attached to nitrogen with a bifunctional compound which contains one or more epoxide and/or alpha-halobeta hydroxy alkyl groups in the molecule, an anionic surface active agent composed of alkyl aryl sulphonates and/or an acid and an anionic softener composed of fatty alcohol sulphates and their drying and heating. The treating composition may contain 0.5-25% of the antistatic agent and 0.25-12.5% of the surface active agent based on the weight of the fabric.  When the treating composition contains an acid this may be acetic acid in an amount which maintains the pH of the composition at 4.8-5.0 and the composition may be heated to 37 DEG C. before the fabric is placed therein and the temperature then maintained at 54 DEG -96 DEG C. for 10-30 minutes at the end of which time sodium carbonate or other alkaline reacting agent may be added to change the pH value to 8.0 or above and the fabric maintained in the composition at 85 DEG C. for an additional 15-30 minutes, rinsed, treated for 5-30 minutes at 37 DEG -54 DEG C. with a mixture of cationic and anionic softeners and dried at 80 DEG -150 DEG C. Alternatively the composition may be applied by padding or spraying.  When an acid is not used sodium bicarbonate or carbonate may be present at the start of the treatment.  The fabrics treated may be made from fibres composed of polyacrylonitrile, copolymers containing at least 85% by weight of acrylonitrile or blends of polyacrylonitrile or a copolymer thereof with 2-50% by weight of another polymeric material, the blend having an overall polymerized acrylonitrile content of at least 80% by weight.  Suitable monomers which may be copolymerized with acrylonitrile are acrylic, a -chloroacrylic and methacrylic acids, acrylates, methacrylates and a -chloroacrylates, vinyl chloride, fluoride or bromide, vinylidene chloride, 1-chloro-1-bromo ethylene, methacrylonitrile, acrylamide, a -chloroacrylamide, methacrylamide methel vinyl ketone, vinyl carboxylates, N-vinyl imides, methylene malonic esters, itaconic acid and esters thereof, N-vinyl carbazole, vinyl furane, alkyl vinyl esters, vinyl sulphonic acid, ethylene a ,b dicarboxylic acids and derivatives thereof, styrene, vinyl naphthalene, vinyl pyridines and 1-vinyl imidazoles.

Title: Solid state light sensitive storage device
IPC: H01L29/00
Filed: 1970-04-01
Abstract: 1309123 Semi-conductor targets; image pickup tubes TEXAS INSTRUMENTS Inc 1 April 1970 [3 April 1969] 15425/70 Headings H1D and H1K A single pn-junction occupies the entire active area of the monocrystalline target of a vidicon or other image tube. The target shown has a high resistivity bulk 34 of silicon, germanium, or of chromium-doped gallium arsenide. On the side to receive optical radiation an n-type zone 36 is formed by diffusion (or by an epitaxial growth method), the zone being surrounded by a guard ring 38 of the same conductivity type. (The guard ring is operated at the positive potential of the target zone 36 or at ground potential). A high resistivity layer 41 is provided on the side of the crystal scanned by the electron beam. The beam potential is such that the depletion region expands from its unbiased extent 35 to occupy substantially the whole of the high resistivity bulk 34 to give a tube of high sensitivity and low target capacitance. In a variant target the optical image falls on an n-type bulk on the other side of which a thin high resistivity p-type zone and surrounding guard ring are formed and covered by a high resistivity layer. In this case the depletion layer is thin giving a tube of higher target capacity and lower sensitivity suitable for use with high light intensities.
