Title: Folding apparatus e.g. for folding linen
IPC: D06F89/00
Filed: 1967-11-10
Abstract: 1,203,043. Folding sheets. E. & E. PETERS G.m.b.H. 10 Nov., 1967 [10 Nov., 1966], No. 51345/67. Heading D1S. A machine for folding sheets comprises a second folding apparatus is positioned downstream of a first folding apparatus, conveying means for conveying the sheets from the first to the second folding apparatus, the second folding apparatus being disposed approximately in the middle of the length of the outlet of the first folding apparatus, and means for controlling, independently of the length of a given sheet, the operation of the second folding apparatus so that the second folding is made exactly in the middle of the once-folded sheet. A sheet (not shown) is deposited on conveyor belts 8 driven at a speed dependant upon that of a previous mangle (not shown) and a first fold is made by a folding platform 31 having pivotable folding arms 12 carrying rollers 13. In the region of the arms 12, riser arms (not shown) are provided between the belts 8 to ensure that the sheet is fed onto the arms 12. When the sheet interrupts a light beam from a source 15 reflected by a reflector 16 to a receiver 14 measuring apparatus is actuated and either a cam disc 40, Fig. 3, or a toothed wheel 51, Fig. 4, starts to rotate. When a switch 45 or 53 is operated by a pin 44 or 55 the arms 12 are moved upwardly from the dotted line position of Fig. 2 to hold the leading edge of the sheet against the platform 31 whilst the remainder of the sheet continues travelling on the belts 8 until the leading edge is dropped onto the trailing edge. When the trailing edge of the sheet clears the light beam a quadruple speed drive is connected to the disc 40 or a toothed wheel 52 for a time until the disc 40 has turned once or a chain 50 running around the wheels 51, 52 has reached a position in which an attachment 56 thereon can again engage a locking member 57. During this movement a switch 46 or 54 is operated by the pin 44 or 55 to cause a pneumatic or hydraulic cylinder 17 to move a pronged folding blade 21 upwardly between the belts 8 to push the centre line of the once-folded sheet upwardly between belts 9, 10, 11 and onto the upper run of the belts 9. Additional guide arms (not shown) may be provided between guide rollers 3, 5 for the belts 9, 10, 11. The belts 10, 11 are arranged alternately. A third folding means 34 similar to the first means 31 may be provided over the belts 9. The distance between the sensing elements 14, 15, 16 and the blade 21 is one-half the length of the longest sheet to be folded. If it is desired to attain a "one-third" folding of the sheet after the first fold, the quadruple speed drive is replaced by a sextuple speed drive and the distance between the sensing elements 14, 15, 16 and the blade 21 is reduced by one-sixth of the length of the longest sheet to be folded.

Abstract: 1527040 Device for binding bag necks F TANGE 9 Dec 1976 [11 Dec 1975] 51404/76 Heading B8C [Also in Division B3] A device for applying binding material, e.g. wire ties, around gathered bag necks comprises a vertically slidable plate 2 which carries a shaft 34<SP>1</SP> for mounting a reel 34 of binding material 35, a feeding mechanism for the binding material, a twisting mechanism for twisting end portions of a cut length of binding material bent over a bag neck, rocking arms 28 which have U-shaped carriers 39 for the bag neck and rotatably mount a winding arm 29 for bending binding material over the bag neck, and a knife 36 for severing the length of binding material from the supply thereof. In operation, a gathered bag neck is placed in the carriers 39 and pressed down causing downward pivoting of the rocking arms 28. Consequently, as the result of meshing between a sector gear 29<SP>1</SP> on the winding arm 29 and a rack 30 carried by the slidable plate 2, a portion of the binding material which has been fed through the twisting mechanism into the vicinity of the winding arm 29, is bent over the bag neck and as a result of engagement between the knife 36 and a push-rod 38, mounted on the rocking arms 28, a length of binding material is severed. Continued downward pressure of the bag neck causes downward movement of the slidable plate 2, against the bias of a return spring 5, by engagement of a plate 39<SP>1</SP> on one of the carriers 39 with the slidable plate. Such movement of the plate 2 operates the twisting mechanism, through a rack and pinion arrangement, to complete the binding of the bag neck. The return movement of the slidable plate 2 operates the binding material feeding mechanism, through a further rack and pinion arrangement, to feed a length of binding material for the next binding operation.

Filed: 1974-11-29
Abstract: 1459540 Data processing system INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1974 [28 Dec 1973] 51738/74 Heading G4A In a system in which data segments may be transferred between a primary working store and a secondary, e.g. disc, back-up store, a header is maintained for each stored segment indicating the time of transfer and counts of the total number of transfers which had taken place previously whereby examination of the header associated with a particular segment enables detection of a possibly erroneous state of the segment caused by an earlier primary store failure (any modified segment in primary store at the time of a failure may have influenced segments which were returned to secondary store before the failure occurred). The header checking and maintenance system is controlled by a special microprogram and includes registers in which system time, iota count and omega count are maintained, the iota count being incremented after each transfer of a modifiable segment from the secondary store to the main store, and the omega count being updated to the lowest value of the iota counts in segment headings in the primary store prior to removal of a segment from primary store. On entry of a segment into primary storage, comparison of the iota count and time recorded in its header with recorded values of omega count and time relating to previous system crashes enables a possibly "premature" segment to be identified. Whenever a segment is to be moved out of primary storage, the headings of segments in primary storage are scanned to determine the lowest value of iota count therein, this value then becoming the omega count. Modification of the heading checking and maintenance procedures when the data segments are paged is also discussed.

Patent GB-526117-A (GB)
Abstract: 526,117. Unsaturated ketones. PEPPER, K. W. March 7, 1939, No. 7423. [Class 2 (iii)] Unsaturated ketones of the type OH 2 X-CO-C#Y in which X is hydrogen or #CH 2  CH 3  or simple homologue and Y is hydrogen or CH 3  are freed from their greenish colour by agitation in the presence of water and an alkali or basic material or sulphur dioxide, sodium bisulphate, hydrosulphate sulphoxylate or similar sulphur compounds acting as reducing agents. The process may be effected by distillation in the presence of an alkali, which involves agitaton. When a reducing agent is employed, the ketone must be washed previous to distillation. The greenish ketone may be distilled with metallic calcium in the presence of water so that calcium hydroxide is formed in situ. Examples describe the treatment of methyl isopropenyl ketone with aqueous sodium bisulphite and sodium hydroxide respectively and with water and calcium, and of ethyl isopropenyl ketone with aqueous sodium hydroxide ; after separating the aqueous layer of the mixture or of the distillate therefrom, the ketone is dried by distillation with calcium. Specifications 404,317 and 408,063 are referred to. In the production of resins from the purified ketones, the polymerization should be effected at temperatures not above 50‹C. without a catalyst or 60‹C. in the presence of a catalyst.

The latter may be a navigational aid station in which periodic instrument readings are made and recorded in digital or audio frequency format without the need for any start signal from the master station. Only the latest set of readings are retained in the recorder memory. Digital readings are converted to V.F. format before transmission. The certain alarm conditions are those which cause the station to be automatically shut down. They cause an immediate set of instrument readings to be taken and recorded in a special store so that the instant condition of the station is sent to the master. The cause of the shut down may be deduced from the instant and previous readings and the master station, e.g. a computer, may cause the station to restart if the alarm is false. The usual security checks as to the identity and authority of the master are made before any data read-out or control functions are effected at the remote station. Various alarm conditions of a non-critical nature (unless they occur frequently) may be recorded with or separately from the data readings. Such conditions may be intruder (vehicle or animal) interference with the navigational radiation pattern, low or high temperature, high winds, displacement of the aid's radiating or monitoring antennae, power failure or low or high voltage.
