Title: Feeding apparatus for ironing machines
IPC: D06F67/04
Filed: 1966-05-25
Abstract: 1,078,640. Laundry machines. VERKSTADS CALOR A.B. May 25, 1966 [June 3, 1965], No. 23452/66. Heading D1A. Apparatus for feeding laundry articles to an ironing machine comprises a beam which is adapted to support the leading edge of an article and is rotatable with a shaft disposed above conveyor means with its axis normal to the direction of feed, a one-revolution coupling adapted to stop the shaft in a position wherein the beam is readily accessible to an operator and adapted, after starting, to move the beam downwards towards the conveyor, and a roller parallel to and rotatable with the shaft and so arranged as to roll over the released leading portion of the article to keep the latter in contact with the conveyor. A hollow beam 8 is rigid with a hollow rotary shaft 7, whereby suction produced in the beam and shaft is applied, via apertures 27, to the leading edge of a sheet supported on the beam. Clamp jaws for releasaibly holding said leading edge are mounted on a carriage 25 slidable on the beam and movable thereon by means of a piston 29 in shaft 7. A rotor 6, journalled on shaft 7, comprises a pair of end plates 10 interconnected by a hollow member 9. Rollers 11a, 11b, 11c disposed with their axes parallel to that of shaft 7, are journalled in the outer ends of arms 12 which are pivoted at their inner ends, at 13, on the plates 10, and which carry intermediately rollers 14 engaging cam grooves 15 in respective fixed plates. The arrangement is such that when stator 6 rotates, the rollers are moved radially in succession from an inner position, as at 11b, to an outer position, as at 11a, in contact with the upper run of conveyor belts 5 carried by a driving roller 3 and driven roller 4. Rotor 6 is driven counterclockwise from the position shown by a one-revolution coupling. Rotor 6 is in turn so coupled to shaft 7 that the latter initially turns slower than rotor 6. Roller 11c thereby moves ahead of beam 8 to engage the upper run of belts 5 at a speed higher than that of the belts, to press the leading portion of the sheet, now released from beam 8, against the belts.

Title: Improvements in and relating to regenerative heat exchangers
IPC: F23L15/02
Filed: 1964-06-08
Abstract: 1,077,132. Regenerative heat exchangers. BABCOCK & WILCOX Ltd. June 8, 1964 [June 8, 1963], No. 23679/64. Heading F4K. In a regenerative heat exchanger, through which hot flue gases and combustion air are alternately passed, by the operation of two sets of valves, the valves of one set are forced against their seatings in withstanding the reaction of the other set being opened. As shown in Fig. 1, a regenerator 10 (which may be one of a line of twelve regenerators whose cycles are temporally staggered) has two sets of valves mounted on respective stems 220, 228 linked via respective pivots 245A, 245B and a lever 246 to a piston 248. Each stem has a spring- loaded catch 242, 244 catch 242 being more easily depressed than catch 244. In operation, flue gas inlet valves 218 and outlet valves 234 are maintained open for 30 seconds after which piston 248 is driven downwardly by compressed air causing catch 242 to be depressed and lever 246 to pivot about joint 245B thereby closing valves 218, 234. Both sets of valves remain closed during the time taken for the lost motion due to springs 240C to be taken up. When springs 240C are fully compressed, further downward movement of piston 248 causes catch 244 to be depressed and valve stem 228 moves downwardly to open valves 226, 240 while valves 218, 234 are forced against their seatings. Valves 226, 240 remain open for 30 seconds during which combustion air can flow through the regenerator. Then piston 248 is driven upwardly to raise both the valve stems. Because of the lost motion provided by springs 240C, valves 226, 240 close before valves 218, 234 open. As valves 218, 234 open, the other valves 226, 240 are forced against their seatings. An alternative embodiment using rotary dampers instead of sliding valves is described with reference to Figs. 2 and 3 (not shown).

Title: Improvements in or relating to systems for detecting and correcting errors in transmitted information
IPC: H04L1/14
Filed: 1964-06-09
Abstract: 1,001,179. Telegraphy. SIEMENS & HALSKE A.G. June 9, 1964 [June 10, 1963], No. 23751/64. Drawings to Specification. Heading H4P. In a transmission system in which data transmitted in blocks is corrected by repetition each received block is returned to the transmitter where it is compared with the block transmitted, and, further, each block is followed by a signal indicating the result of the comparison, this signal also being returned and compared, and if found to be faulty repeated. Parallel data from a tape reader is converted to serial form and transmitted as a block which is also stored. When the store is full the tape reader is stopped. The received block is stored and returned to the transmitter where it is compared with the stored block. If there is no error a signal to that effect is transmitted causing the receiver store to read out to a tape perforator. The no error signal, being returned to the transmitter, is compared with the stored no error signal and if correct the transmitter store is erased and the next block transmitted, but if incorrect the no error signal is repeated. If the block comparison indicates error an error signal is sent, causing the receiver store to be erased. The error signal is also compared with itself at the transmitter and, if faulty, is repeated or, if correct, initiates repetition from the store. To decrease error probability the signals on the return channel may be converted such that characters containing an odd number of mark bits are inverted.

Abstract: 891,789. Extrusion machines. WELDING ENGINEERS Inc. July 28, 1958 [Aug. 15, 1957] No. 24190/58. Class 87(2). An extrusion machine comprises a pan of screws in parallel intersecting bores, the screws having flights of at least two dissimilar sections, the first section being non-positive with flight spaces appreciably larger than the flights and the second section being positive and having interpenetrating flights closely fitting the bores and having substantially equal flights and flight spaces. Two screws 35, 36 are located in casings 20,21 having liners 27,28, an inlet 31, a vent which may be under vacuum and a die 32 with orifices 33. The screws 35, 36 have five sections A to E. In section A the interpenetrating flights of one screw occupy a small portion of the flight space of the other screw allowing the material to partially rotate with the screws giving a non- positive forwarding action. The pitch of the flights gradually decrease towards section B where the flights of one screw have only a slight clearance in the flight space of the other screw allowing almost no rotation of the material with the screws and giving a positive forwarding action. In section C there is again a large clearance of the interpenetrating flights, which may have radial slots 59 and the pitch of the flights gradually decreases towards Section D where again the flights have only slight clearances in the flights of the other screw. Section E discharges the material through the die. Each section of the screw has a greater forwarding capacity than the section to which it discharges. In Fig. 2 (not shown), not all the sections have interpenetrating flights. Specification 733,911 is referred to.

Title: Motion picture film cassettes
IPC: G03B31/00
Filed: 1974-05-31
Abstract: 1471614 Film cassettes POLAROID CORP 31 May 1974 [28 June 1973] 24347/74 Heading B8M [Also in Division G2] The invention relates to a cassette in which there is a film strip of the kind provided with a sound track area extending along one edge as well as to a method of driving said strip. The object of the invention is to overcome the problem of the incremental motion that will be imparted to the film strip by the sprocket drive mechanism of the projector in which the cassette can be mounted. This "jerky" motion must be isolated from the transducer head that scans the sound track. According to the invention the cassette 18, Fig. 4, has one or two apertures permitting the introduction of a transducer head 90 and a constant speed drive means 94 such that the film 22 can be advanced past the transducer head 90 at constant speed; constricting means 70 between an exposure and/or display station and the transducer head 90 for preventing the film from buckling out of the plane of the film strip, and the whole being so arranged that a free loop 120 of the film is formed to act on a store that allows intermittent motion of the film past the projector lens but constant speed motion past the transducer head 90. As shown the free loop 120 extends through one of the apertures. The cassette includes a roller 28 against which the film strip 22 is pressed by the drive means 94. The cassette includes a film processing station 30 comprising a first compartment 58 containing a processing fluid 52. The fluid can be released into a compartment 54 on pulling a tear-tab 60. When the film has been exposed by running from reel (26) (not shown in Fig. 4) to reel 24 it is processed by running it back to reel (26) via the compartment 54. A doctor blade element 66 below the film results in the correct layer of developing fluid being deposited on the film. Fig. 3 shows how at least the roller 28 has a centrally depressed area 108 and raised edges 110, 112 to ensure that the roller 28 engages the film strip 22 at its edges only. The film strip 22 has a support layer 100, an emulsion layer 102, and a pair of narrow rails or strips 104, 106, one on each of the longitudinal edges of the film strip and extending the full length thereof. At least one of the rails carries the sound track. The rails 104, 106 provide an air space between the emulsion layer 102 of one turn and the support layer 100 of the next turn when the processed film is wound up. An electric eye 118 causes the incremental motion to speed up if the loop 120 becomes two large. When the loop reverts to normal size the electric eye 118 causes the incremental motion to revert to normal.
