Title: Pilot-operated three way electromechanical valve
IPC: F15B13/043
Filed: 1971-09-28
Abstract: 1315880 Valves SIRAI SRL SOC ITALIANA REGOLATORI AUTOMATICI INDUSTRIALI 28 Sept 1971 [28 Sept 1970] 45107/71 Heading F2V A pilot-operated valve comprises an inlet 10, outlet 12 and exhaust 14, the outlet being selectively connectible to exhaust (as shown) via a passage 62 of a member 64 which is spring- loaded to prevent communication between the inlet and outlet, and to the inlet 10 when a piston-member 52 is moved to firstly close the passage 62 with its lower face and with continued movement move the member 64 away from its seat against the spring force. The movement of the piston member 52 is controlled by an electronmagnetically operated pilot valve having an armature 24 housing two pistons 22, 26 spring-urged outwardly on to fixed abutments, the pistons serving as valve members for parts 20, 28 respectively. A fluid passageway 16 leads from the inlet to the port 20 through which fluid can flow to the chamber 48 above the piston-member 52. Under these conditions piston-member 52 is moved downwardly to allow communication between inlet and outlet as described. When the electromagnet is energized the armature 24 is moved against a spring 44 to close the part 20 and open the part 28. The chamber 48 is then exhausted via port 28 and the piston member 52 is moved upwardly under fluid pressure to allow communication between the outlet 12 and exhaust 14.

Title: Conveyor system
Inventor: SMITH JOHN W
IPC: B65B35/24
Filed: 1964-11-09
Abstract: 1,029,379. Endless conveyers. BATTLE CREEK PACKAGING MACHINES Inc. Nov. 9, 1964, No. 45643/64. Heading B8A. Pairs R of toilet tissue are fed to a packaging machine 13 (Fig. 2A, not shown) by belts 10, 10 (Fig. 3, not shown) until they reach a stop-plate 86 and operate switches 87. This energizes drive means for an elevator plate 81 (on which the rolls now stand) and the latter is raised to its full line position so that the rolls R are brought within the travel of depending pushers 115. These feed the rolls on to abut a stop 54 and they then overlie chains 27 which carry push-plates 52. Shoe portions 51 of the plates 52 engage antifriction track strips 45 (Fig. 5, not shown). At the forward end of the conveyer chains 27, the shoes 51 drop off the end of the track strips 45 and permit the plates 52 to tilt rearwardly. Thus they clear the rolls R which at this stage are raised by an elevator 21 to the level of a pusher 22 which feeds the machine 13. The rolls R are centred on the conveyer 27 by side walls 54, each of which carries a series of spring-loaded centring pads 62. A sensing feeler 121 acts to stop paper feed to the wrapping machine 13 when it detects the absence of a pair of rolls R. The spacing of the walls 54 is manually adjustable by operation of a handle 72 to accommodate single rolls or pairs of side-by-side rolls. Also rolls on the conveyer 10 may be in pairs formed by axially adjacent single rolls (or single pairs of laterally spaced rolls) or may be in single roll (or single pair) formation. Provision is made for adjusting the position of the mounting of the chains carrying the pushers 115, to cover these alternatives. Each pusher 115 is pivotally mounted on its associated conveyer chain 94 and is connected to another point on the chain by a link 117, so that the pusher remains substantially vertical during the movement of the conveyer chains round the forward return sprockets.

Title: Apparatus for testing the position of standing bowling pins and for raising the bowling pins in a pin setting machine
IPC: A63D5/08
Filed: 1964-11-10
Abstract: 1,079,740. Bowling alleys. PATENTVERWERTUNGS-UND FINANZIERUNGSGESELLSCHAFT SERANIA A.G. Nov. 10, 1964 [Nov. 11, 1963], No. 45829/64. Heading A6D. A device for respotting standing pins on the playing deck of a bowling alley comprises pairs of pivoted gripper arms, one pair for each pin, the arms of each pair being operated to close upon the neck of the associated bowling pin by a driven member mounted on one arm and linked by means of a lever with the second arm. Preferably the arms 13, 14 of each pair are mounted for independent rotation about a spindle 16 fixed on a plate 10 of the pinsetting table of the bowling alley, adjacent an aperture 12 in said plate through which the head of a standing pin projects when the table is in its lowermost position. The gripper devices may be driven by an electric motor using an endless chain passing over sprockets attached to the gripper devices, may be held in a movable pin setting carriage and in order to prevent pins being displaced during the gripping operation pressure may be applied to the pins by means of pressure plates as set forth in Specification 1076397.
Patent GB-1062936-A (GB)
Title: Improvements in and relating to cold-stretching of films
IPC: B29C55/06
Filed: 1963-11-21
Abstract: 1,062,936. Polyolefin films. OLE-BENDT RASMUSSEN. Nov. 21, 1963, No. 46060/63. Addition to 987,776. Heading B5B. In the cold-stretching of a film of highdensity polyethylene or isotactic polypropylene, the film is subjected to an initial stretching in evenly spaced longitudinal zones, said initial stretching being effected by passing the film under tension over a surface corrugated in the direction of movement of the film, e.g. a grooved bar or a cross-fluted roller, the conditions being such that orientation of the film is initiated while the film is passing over the surface in the zones of the film in contact with the raised parts of the corrugations, e.g. at the tops between the grooves or flutes, but not in the intervening zones. The initial stretching ratio may be between 1À1:1 and 1À4: 1, especially about 1À25:1. Preferably, the corrugations have flat tops. If desired, a foreign material, e.g. polyisobutylene or polyvinyl isobutyl ether may be incorporated in the film-forming material before extrusion, suitably in a proportion of 5-16% by weight. In Fig. 1, a film 5 of the material to be stretched is stretched between the pairs of rollers 6, 7 and 9, 10, while passing over the grooved bar 8, of semicircular cross-section and not over 12 mm. in width. As shown in Fig. 2, the grooves are of semicircular cross-section, and the width of the projections is substantially equal to the radii of the semicircular grooves. Stretching over, the bar produces a fine pattern of shearing lines parallel to the axis of the grooved bar, shown in (Fig. 3, not shown) and further stretching between the bar and the rolls 9, 10 produces a criss-cross pattern of shearing lines (5). To fully develop the shearing line pattern, the film may be passed twice more through the stretching apparatus, and thus stretched to about double its length. Each stretching step reduces the width of the film by about 10% and the thickness by about 15%. Subsequent roomtemperature stretching, using water-cooling, to about 400% of the original length causes the disappearance of the shearing line pattern, to reduce a strongly longitudinally oriented film.

Title: Electrical Appliance with a Gaseous Filling Consisting at least Partly of Sulphur Hexafluoride
Inventor: HUGI LITTY
IPC: H01H33/56
Filed: 1967-10-09
Abstract: 1,152,754. Gas analysis; indicating apparatus. BROWN, BOVERI & CO. Ltd. Oct.9, 1967 [Oct.10, 1966], No.46101/67. Headings G1B  and G1J. [Also in Division G4] An electrical appliance, the interior of which is filled with a gas consisting at least partly of sulphur hexafluoride, includes a device for indicating the presence of gaseous contaminants produced by decomposition of the sulphur hexafluoride. The device consists of a housing 8a containing a contaminant absorbing material 21 exposed to the gas and comprising a granular material containing OH ions such as activated alumina. The granular material is dyed with an indicator, the colour of which changes in the presence of the gaseous contaminants. The housing 8a is sealed to a flange 18 in a wall 2 of the appliance by a gasket 20 and screws 44. A wire grid 22 is situated at one end of the housing whilst the other end of the housing is sealed by an inspection glass 29 and gaskets 27, 28. A cover 31, having a colour comparison table 32, protects the indicator dye from fading under the action of light. To remove the housing 8a without losing the gas in the appliance, screws 35, 37 are loosened so that a gasket 41 of a cover 38 seals against the inside of the flange 18 due to the excess pressure in the appliance. The table 32 may be replaced by a manometer fitted to the inside of the inspection glass. A ring 52 showing the colours that the dye undergoes rotates with the manometer needle 50 which indicates the pressure in the appliance. A further ring 54 indicating the percentage by volume of the contaminants surrounds the coloured ring so that at a given pressure of the gas in the appliance, the percentage of contaminants may be read off at the position on the outer ring corresponding to the existing colour of the dye.

Title: Acceleration responsive devices
IPC: F16K31/02
Filed: 1968-09-27
Abstract: 1,240,692. Detecting vibrations; sensing acceleration. HONEYWELL Inc. Sept. 27, 1968 [Oct.18, 1967], No.46121/68. Headings G1J and G1K. Apparatus, for providing a fluidic output signal when excessive vibrations occur in a system, comprises a mass 12 held in one position during accelerations below a predetermined value but movable, when that value is exceeded, to another position, where it is held, a fluidic relay 13 producing a signal when this position is assumed. The mass 12 is mounted to oscillate about a vertical axis 16 by a flexible hinge 16 and has arms of magnetic material whose ends 12A, 12B are influenced by magnets 50, 51 attached to stops 30, 32 and also by a spring 20, tending to turn the mass 12 clockwise, which may be adjusted and locked by screws 19, 21 to predetermine the critical value of acceleration. The apparatus is set initially with the end 12A in contact with an adjustment screw 31 in magnet 50. When vibrations occur producing a force large enough to dislodge end 12A from magnet 50, the end 12A moves away from magnet 50 as end 12B moves towards magnet 51 causing a respective decrease and increase in the forces of attraction so that the end 12B snaps against magnet 51. This causes a member 35 to move towards the relay 13 (see Group G3) and to tilt a trip bar 36. This unseats a ball valve allowing fluid to flow from a passage 40 into the relay 13 so that the pressure in a passage 43 decreases sharply, providing a signal which may be used to actuate a fluidic amplifier. Mechanism shutting down the whole system (e.g. a natural gas line pumping system) may be operated by the amplifier fluidic signal. To avoid shut down due to temporary excessive vibration e.g. when starting, the apparatus may be automatically reset a pre-set interval after each signal. To this end unseating the ball valve also allows fluid to vent from a pressurized chamber 106 in the reset mechanism, Fig. 4, through a restriction 44A in a passage 44 and the relay exhaust 41. As the pressure in chamber 106 decreases a spring 103 pushes a diaphragm 100 down retracting its central pin 101, allowing a leaf-spring 84 to push a resetting bar 45 which pushes both the end 12A against magnet 50 and trip bar 36 to initial position. When automatic resetting is not wanted, a resetting selector arm 82 is turned to a manual position in which an inclined ridge 90 prevents the spring 84 from moving down when the pressure in chamber 106 diminishes. However the end of spring 84 can bend when a manual reset button 105 is pushed.

Filed: 1966-10-17
Abstract: <PICT:1091267/C6-C7/1> In a process for depositing the thin film of a material (e.g. Ni-Cr alloys, Al or Au) on a substrate by sputtering, e.g. for making a thin film resistor element, the thickness of the film is monitored by measuring the ion charge to the target.  The sputtering gas (Av) and the non active gas (H2) within the chamber must be brought to predetermined ratios thereof to establish a known sputtering yield per incident ion.  In Fig.1 the targets 9 and 11 are placed opposite substrates 25 which are supported on a rotatable octagonal structure 23 and there are annular shutter elements 29 and 29' to protect substrates which are not being sputtered at any given time.  The ion charge to target 9 is measured by the integrating circuit 49 which actuates switch 51 when a layer of the desired thickness has been formed. The target 11 and its associated machinery is used for depositing a protective layer of Al, or Au over the resistor of Ni-Cr alloy. A process of applying resist, etching and further sputtering for the manufacture of circuit arrangements is also disclosed.
