Patent GB-253200-A (GB)
Abstract: 253,200. Mottershead, W. March 13, 1925. Tickets, holding.-A box a is divided into compartments each adapted to receive a ticketholder 1 - - 8, and means are provided to lock the holders in position so that only one can be withdrawn at a time. The holders, each of which is made to take, say, six piles of tickets, consist of a base t, Fig. 7, end plates v, division plates w, x, and spring clips 14, 11. The bases slide under guides 16 in the box ,and over flat springs 17. Each holder has a notched tongue 18 which co-operates with a corresponding flanged locking disc 20 on a rotatable shaft 21 housed in a compartment at the back of the box. Each disc 20 has a slot 25 which permits the holder to be withdrawn or inserted when the shaft 21 is in a particular position. When a holder is withdrawn, the others are all locked, and the shaft 21 is locked against movement by a spring 51 which enters the slot 25 corresponding to the holder which has been withdrawn. The shaft 21 is moved step-by-step by a pawl' and ratchet device 37, 30, movement of the pawl lever 34 being limited by stops. Numbers marked on the disc 30 indicate which of the holders is unlocked at the moment, and a graduated disc 39, which is moved one step for each complete revolution of the shaft 21, indicates the number of complete journeys made by the vehicle. A pawl and ratchet housed in a casing 50 prevents reverse movement of the shaft 21. The discs 20 may be separate from and keyed to the shaft 21. and they may be flanged on both sides. The shaft 21 may be arranged vertically. A partitioned drawer g is arranged in the base of the box to carry an extra supply of tickets. In use, a different ticketholder is taken out for each fare-stage of the journey, and the holders carry decreasing numbers of piles of tickets.

Title: Improvements in wrapping apparatus
Inventor: BROOK LEONARD
IPC: B65B23/18
Filed: 1959-07-23
Abstract: 886,509. Packaging. FORGROVE MACHINERY CO. Ltd. July 6, 1960 [July 23, 1959], No. 25346/59. Class 94 (1). A biscuit wrapping machine has a first mechanism for folding a corrugated wrapper around a batch of biscuits so as to form an open-ended sleeve, and a second mechanism for applying an outer wrapper having a sealed joint offset from the joint in the inner wrapper. Batches 3 of round or oval biscuits on an intermittently moving conveyer 1, are raised at station B, between plungers 5 and 6, to a station C where they are held by spring loaded grippers 9 whilst the lower plunger 5 descends to a position, as shown, level with a support plate 10. A corrugated wrapper 11 is fed on to the plate 10. The lower plunger 5 is then raised to trap the wrapper 11 between the biscuits and itself, the grippers 9 open, and the plungers 5, 6 descend to return the biscuits to the conveyer 1, this action causing the support plate 10 to fold the wrapper 11 to U-shape. At station D the tails 11A of the wrapper are turned down by folders 18 and 19 and a short strip of adhesive tape is applied by known means over the joint. The wrapped biscuits are then carried to a further station (not shown) where they are raised against a wrapper of waxed paper or heat sealable film. The outer wrapper is then sealed at the bottom of the batch of biscuits. This seal is diametrically opposite to the joint of the inner wrapper 11. Feeding inner wrappers. The inner wrappers are stacked in a magazine at the rear of the mechanism shown and the lowermost wrapper is displaced by a reciprocating plunger such that it is fed between rollers on each side of the path of movement of the plunger 5 at the level of the plate 10. Endless belts, driven by the lowermost rollers, carry the wrapper beyond the rollers. Alternatively, instead of feeding the corrugated sheets from a stack, a continuous web of corrugated paper may be fed from a reel in a direction parallel to the length of the conveyer 1 into the position occupied by the magazine, and sheets are then cut periodically therefrom and delivered into position for wrapping by said rollers and endless belts.
Patent GB-869362-A (GB)
Title: Fertilisers based on urea-formaldehyde resins
Inventor: BUTTREY DOUGLAS NORTON
IPC: C08G12/12
Filed: 1958-08-07
Abstract: An insoluble resin useful as a fertilizer is prepared by reacting, under acid conditions, an aqueous condensate from 1 mol of urea with 1,2-3,5 mols of formaldehyde, with sufficient urea to bring the proportions up to 1,2 - 1,8 mols. of urea per mol. of formaldehyde. The acid conditions may be produced by any of the usual acid or latent acid catalysts for ureaformaldehyde resins, e.g. sulphuric acid or ammonium chloride.  The condensation may take place in presence of other fertilizers, e.g. ammonium sulphate, or superphosphate and this other fertilizer may provide the necessary acidity.  In the example 2,2 mols of formaldehyde (as formalin) were refluxed with 1 mol urea at a pH of 7,5 for 15 minutes.  The pH was adjusted to 4,0 with formic acid and refluxing continued.  The pH was then re-adjusted to 7,5 with caustic soda and the solution concentrated in vacuo to 70% solids.  Further urea and ammonium sulphate were added and the mixture heated.  The precipitate after powdering and drying was a fertilizer suitable for lawns or fairways.ALSO:A fertilizer is produced by reacting under acid condition an aqueous condensate from 1 mol. of urea and 1,2-3,5 mols of formaldehyde, with sufficient urea to bring the total proportion to 1,2 to 1,8 mols. of urea per mol. of formaldehyde.  The condensation may take place in the presence of other fertilizers, e.g. ammonium sulphate, superphosphate, some of which, e.g. ammonium sulphate may provide the necessary acidity for the condensation.

Title: Safe torque drivers
Inventor: BETTER BERNARD RAYMOND
IPC: F16D43/204
Filed: 1956-08-20
Abstract: 809,520. Drilling; screwing-up nuts &c. SCULLY-JONES & CO. Aug. 20, 1956, No. 25429/56. Class 83 (3). [Also in Group XXIV] A safe-torque clutch for driving drills or taps, of for setting nuts and studs, comprises a driving shell 15 having a degree of resilience and a cylindrical bore, a driven member 18 with two oppositely-disposed cam flats 27, 28, adjacent flats 31, 32, and connecting eccentric surfaces 33, 34, and a pair of diametricallyopposite rollers 29, 30 between the members retained by a cage 37. For forward-driving in the direction of the arrow in Fig. 7, the rollers 29, 30 assume the wedge-driving positions shown, and torque is transmitted to the driven member 18. On the safe torque being exceeded the rollers ride over the high-spots of the camflats 27, 28 with deformation of the shell 15, and down the surfaces 33, 34 to release the drive. The rollers are retained in non-driving positions by the cage 37, which has a limited rotation relative to the driven member 18, provided by a lug 41 thereon engaging in a part-circular recess in the end of the cage. On reversal of the drive, the rollers 29, 30 roll up the surfaces 33, 34 to their original positions on the flats 27, 28. The value of the safe torque to be transmitted can be adjusted by reducing the effective length or diameter of the rollers. In a modification the outer surface of the shell 15 is conical and a mating conical sleeve is screwed over it with an adjustable clearance, or with any desired degree of pressure so that the resistance to deformation, and hence the transmissable-torque, may be varied.

Title: Web Transport System.
Inventor: FEASEY RAYMOND DAVID JOHN
IPC: G03D3/13
Filed: 1967-06-05
Abstract: 1,180,961. Feeding webs. EASTMAN KODAK CO. 5 June, 1967 [6 June, 1966 (2)], No. 25836/67. Heading B8R. [Also in Divisions F2 and G2] A support roller such as is used in transporting film strip through a processing system comprises a flanged spool 20 having a rigid rim 24 bounded by the flanges 23, and a rigid hub 32. Rim and hub are maintained in concentric relation by flexible connecting means, which may be two spiral members 31 as shown in Fig. 3, or an annular member of foam rubber (36, Fig. 4, not shown). If any variation in tension occurs as the film passes over such rollers (e.g. because of stretching or shrinking), the rim can be displaced relative to the hub. Fig. 1 is an arrangement in which the film is passed through a processing tank over a set of upper and lower rollers 20, 22. The upper rollers rotate so that they are just out of contact with a drive roller 26 mounted on a drive shaft 18. If tension in the film increases, the rims of rollers 20 are displaced downwards so that they are brought into contact with drive roller 26. This is rotating at a slightly faster speed than rollers 20, so that the speed of the film is increased, so relieving the tension beyond that point. In the modification of Fig. 5, a drive roller 52 is secured to a drive shaft 50 by a set screw 54. A film support spool 55 having a rigid flanged rim 56 is mounted freely on shaft 50 by means of a loosely fitting rigid hub 66. Normally the spool 55 rotates concentrically round drive roller 52 but is just out of contact with it. Hub and rim are connected by spiral flexible members 68 of involute shape (see also Fig. 6, not shown). Thus when film tension is increased, as by shrinkage, the rim is displaced against the spring members 68 until the inner surface of spool 55 comes into contact with drive roller 52, and is hence driven at a slightly faster speed, until the increased tension is reduced, and the reverse " de-clutching " action takes place.

Statistical apparatus.-An apparatus for determining and printing examination results comprises a master card perforated to represent the correct answers to a series of questions and means for comparing it with the various cards perforated by the candidates. In one portion of a baseboard 5 is a raised space 9 for receiving the master card. This space contains a field 12 of jacks connected electrically in columns and each column being wired to similar columns of jacks in another raised space 24 in which the candidates card is placed. Between the two card spaces is a board 8 containing jaclis 16 arranged in columns allocated to percentage, values 2, 3, 4 &c. These columns are connected by leads 17 with respective magnets 18 each capable of advancing a pair of duplicate type wheels through an angle representative of the percentage value. The cards .are punched by the candidates in the columns denoting the answers considered by them to be correct; thus in Fig. 3, the candidate has answered question 1 by perforating at 7. To examine the results the master card 6 and candidates card 7 are placed in position and removable plugs connected by wires 32 are inserted in the correct answer perforations in the master card and in the corresponding percentage value holes in the board 8. A contact arm 22 is now drawn over the candidate's card and if in any particular question the correct answer has been given circuit is completed through one of the magnets 18 and the type wheels correspondingly advanced. When the card has thus been felt throughout all its lines a key 33 may be depressed to print the total marks obtained on the card 7 at 31 and on its stub portion 28 at 29. The candidates' cards may be compared with the master card by manual superposition and to assist in comparison and identification the latter card may be of a distinguishing colour.

Title: Improvements in filling severing means for automatic filling replenishing looms
IPC: D03D45/20
Filed: 1921-10-04
Abstract: 190,277. British Northrop Loom Co., Ltd., (Northrop Loom Co.). Oct. 4, 1921. Shutttes, changing weft-carriers in, automatically; weft, cutting.-When the starter-rod 9, Fig. 5, of the weft-replenishing mechanism is turned under the control of the feeler mechanism, a pivoted positioner-arm 37 is lowered by lever mechanism 45, 47, 42 and acts on a roll 31, Figs. 2, 3, and 5, on a plunger 30, which is thereby depressed against the action of a spring so as to project a roll 35 into the path of a plunger 21 slidable in a frame in the shuttle. As the shuttle enters the shuttle box at the replenishing side of the loom, the plunger 21 is depressed by means of the roll 35 against the action of a spring, and, by a pin-and-slot connection, turns a pivoted cutting-blade 19 in the shuttle from the position shown in Fig. 2 to that shown in Fig. 3. This movable blade coacts with a fixed blade to cut the weft extending from the weft-carrier to the shuttle eye. The weft end extending from the cutter 19 to the shuttle eye is drawn out of the shuttle, as the shuttle completes its pick, whilst that extending from the cutter to the weft-carrier is ejected from the shuttle with the depleted weft carrier, when this is ejected by the incoming weftcarrier. The former weft-end is engaged by a block 53 of weft-adherent material, such as felt, which is carried by an arm 50 connected by lever mechanism 61, 63, 58, 56, 54, 45 to the starterrod 45, the lever mechanism including a yielding link 61, so that, as the rod 45 is rotated, the block 53 is yieldingly pressed against the side of the shuttle. The weft-end is thereby clamped against the shuttle and is caused to be embedded in the block 53 as the shuttle completes its pick, whereby it is held in position to be clamped by the usual shuttle feeler, so that it may be subsequently cut by the usual temple cutter. The shuttle feeler is furnished with the usual device for clamping, or cutting and clamping, the weft.
