Abstract: 1,153,427. Air-cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 3 June, 1966 [9 June, 1965], No. 24355/65. Heading B7K An air-cushion vehicle 1 comprises a hollow body 4 forming a plenum chamber for air delivered by a fan 16, and a plenum chamber type air-cushion space 3 having an upwardly sloping front wall or prow portion 5 to which are attached contiguous U-section loop members 10 of flexible material constructed as described in Specification 1,043,351, air being delivered to the interior of the loops through apertures 18 from the upper plenum chamber. The rear wall comprises a flexible transverse looped member 9 having U-section loops attached thereto, with the lower forward-facing edges closed by sealing panels to prevent the scooping of water. The side wall portions are similarly constructed, but without lower closing panels, as described in Specification 1,141,601. In a further embodiment (Fig. 5, not shown), the front skirt comprises a looped portion (30) secured (as at 33) to the prow and having attached thereto contiguous U-section loops (31) which are connected to flexible ties (36) which may be extended or retracted by hydraulic motor (37). In a still further embodiment (Fig. 11, not shown), U-section looped members 10 are secured at their leading and trailing ends to the extremities of a prow member which is upwardly cranked and provided with ties (60) secured intermediate the ends of the loop members. In any of the embodiments air supply apertures 18 for feeding pressure air to the interiors of the looped members may be formed in a plurality of groups each fed by its own fan 16, the fans being controlled automatically by speed controllers 66 in response to changes in the attitude of the vehicle as detected by pressuresensitive probes 65 arranged round the periphery of the cushion space. Alternatively, the probes 65 may be fed with pressure air to discharge on to the surface 2 over which the vehicle operates, so that vertical movement of a probe with respect to said surface results in changes in back pressure in the ducts supplying the probes and to which devices 66 would be sensitive.

Title: Apparatus for making prints from colour negatives
Inventor: THADDEY KURT
IPC: G03B27/46
Filed: 1968-05-24
Abstract: 1,213,213. Printing colour negatives. CIBA Ltd. May 24, 1968 [May 31, 1967], No.25014/68. Heading G2A. Apparatus for making prints from colour negatives comprises a printing machine 10 at which successive negatives of a series are automatically exposed on to positive printing paper 20, there being means for preventing the copying of over or under exposed negatives; and a viewing table 11 at which the developed prints 42 are examined and a further exposure of the negatives of unsatisfactory prints made. Printing. During a first passage through the machine 10, a negative film 15 consisting of a series of colour negatives joined together is intermittently fed from right to left (in Fig.1) through an exposure station 16 where it is illuminated by a light 17. Light passing through a negative falls on a brightness measuring device 23 which, if a negative is unprintable, causes first marking means 32 to notch an adjacent film edge and feed mechanism 29 to advance the film 15 to the next picture. If the negative is printable, the device 23 sends signals to an electronic control 25 which controls the speed of a shutter 24 for each colour component, e.g. the primary colours, and the printing paper, fed from left to right, is exposed. A second marking means 33 applies a picture end mark for each print to the back of the paper 20, and a third marking means 34 applies a mark to indicate the end of each individual negative series by reference to the joints. The paper 20 is developed when all the film 15 to be copied has been wound past the exposure station 16. Inspection. The developed positive paper film 42 is fed stepwise past a viewing window 41 from right to left, while the film 15 is simultaneously and synchronously fed from left to right past the exposure station 16. Picture and series end mark detectors 30, 31 are utilized to establish this synchronism. If an unsatisfactory print appears at the window 41 it is marked as being unsuitable and immediately printed again by re-exposing the corresponding colour negative at the exposure station, the correct exposure being assessed by the operator and set on keys 48. When a negative measured as unprintable in the first passage of the film 15 arrives at the exposure station, a sensing device 67 detects the notch and prevents the film feed 29 from stopping until a printable negative appears at the exposure station. Collation. A table 12 between the printer and the viewer receives the negative film 15 which is cut by means 62 as required for packing, and the print film 42 which is cut by means 62. The positives and negatives arrive at the table 12 in synchronism and are placed by the operator into bags for despatch, an order containing faulty prints being retained until the second positive paper film has been developed and the corrected prints available.

Abstract: 1328416 Blasting WHEELABRATORFRYE Inc 19 April 1971 [13 April 1970] 25019/71 Heading B3D A centrifugal blasting wheel comprises a rotatable side wall 8, a plurality of angularly spaced radially extending blades 18 mounted on the side wall, each blade terminating short of the axis of rotation to form a central opening 20, and particulate material propelling means 56 removably mounted in the central opening, the length of each blade in the radial direction being slightly less than the diameter of the opening whereby the blades may be removed through the opening. The side wall is formed on a rear disc secured to a hub 2 on a shaft 4 and by spacers 14 and bolts 16 to a front disc 12. The blades extend beyond the outer edges of the discs and their inner edges define the central opening 20 in which is a control cage 28 and an impeller 56. The control cage has a discharge opening 54 and is secured to a housing 42 of the wheel by lugs 40 having fingers 38 engaging selected ones of a plurality of notches 36 in a flange 34 of the cage whereby the angular position of the discharge opening is adjusted. The impeller 56 has vanes 60 and is secured by a bolt 64 to the shaft 4. Particulate material is fed by a feed pipe 66 from a hopper to the impeller. Each blade is formed with side walls 68, 70 engageable in slots 76 in the discs 8, 12 and radially outward movement of the blade is limited by stops 72, 74 engaging stops 78 in the slots. The side walls extend from the radially inner ends of the blade to a point intermediate its length. When the feed pipe 66, control cage 28 and impeller 56 are removed, the blades, which have a length slightly less than the diameter of the central opening, can be moved radially inwards into the opening for removal from the wheel when worn. During use, inward movement of the blades is prevented by the particulate material binding the blades in their slots. The blades are reversible so that the wheel may operate in either direction of rotation and some of the blades may be longer than others.
