Patent GB-345967-A (GB)
Abstract: 345,967. Adding and subtracting m a c h i n e s. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.- (Assignees of Magnus, J. H.; 6533, 16th Street, Detroit, Michigan, U.S.A.) Dec. 31, 1929, No. 39899. Convention date, March 20. [Class 106 (i).] In a calculating machine for example of the key-responsive type described in Specification 314,789, [Class 106(i), Calculating &c.], means are provided for facilitating the registration of the nines in the higher denominations when subtraction by addition of the complement is being performed. Each bank except the lowest has a column key 70, and when the complement of the subtrahend has been added the key 70 of the bank next above the highest concerned in the calculation, is depressed and this results in the addition of nine in the bank and in all banks to the left. Each key 70 is slotted to engage over a stud 72, Fig. 3, on a multi-armed lever 73, Fig. 4, one arm 76 of which abuts against the usual motor-release bar 36. Thus depression of the key will start the machine and the corresponding differential bar 15, Fig. 5, will be operated to add nine. A laterally extending arm 85 of the lever 73 engages the arm 76 of the lever to the left so that depression of one key 70 results in the operation of all the differential bars to the left. To prevent depression of a column key and an amount key in the same bank at the same time, a lever 91 stands with its upper end adjacent to the first of the usual crowding lock plates 90 and is rocked into engagement therewith by the movement of the lever 73 acting through lug 93 and cam slot 94. Specifications 24996/11, 6/15, and 4131/15, [all in Class 106 (i), Calculating &c.], also are referred to.

Title: Improvements in or relating to the manufacture of covering materials for floors, walls or the like
IPC: D06N7/00
Filed: 1928-11-26
Abstract: 301,321. M³ller, A. Nov. 25. 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Ornamenting.-In the manufacture of covering materials for f1oors, walls, furniture, &c., and particu1ar1y of materials having jasper or marble colour effects, a suitable backing, such as linoleum or tarred board, is first coated with a ground colour, to which different colours, to give the design, are then applied, for example, by spraying. The colours used are composed of a oellulose ester, a solvent, such as ether, benzyl acetate, butyl acetate, butyl lactate, or benzene and its homo1ogues, a pigment, and a suspension medium. The suspension medium consists of drying or semi-drying oils, such as linseed or wood oil, together with esters of alcohols containing four or more carbon atoms, such as butyl, amyl, or benzyl acetate, and resins soluble in these two components, such as mastic, manilla, or kauri copal. The covering colours have solvents of different constitution and different specific gravity, and may have incorporated therein an esterification product of fatty acids, such as linolenic, linolic, oleic. or stearic acid. The colours forming the design may be applied to the material i by means of spraying-devices c, in the form of the known spray-guns, to which colours are supplied from containers a, and compressed air from a pipe d. The triggers of the sprayguns are contro11ed by cams h on a shaft g, and the amount of opening of the jets is regulated by cams on a shaft r. The fabric is supplied with a coating of colour from a tank k. For the production of a jasper colour effect, a spreading- device, such as a brush q, is emp1oyed to give a 1ongitudina1 structure to the design. For marble effects, a soft, resilient, smooth spreading- device is used. The spraying-jets may be given a motion relative to the fabric. A non-repeated design, which has a certain, but not an exact, regu1arity is obtained.

Title: Improvements in artificial arms
IPC: A61F2/58
Filed: 1920-12-13
Abstract: 176,530. Hoare, C. G., and Waters, T. C. Dec. 13, 1920. Limbs, artificial.-A lock for an elbow-joint comprises a pair of spring-pressed pawls G engaging the internally toothed rims of a drum C fast on the pivot pin D, which is fixed to the forearm and is rotated in bearings in the upper member A by the strap H. The pawls are riveted to a member E which slides in guides F in a ring F' mounted within, and concentrically with the axis of, the upper arm member, springs 2 normally holding the pawls in engagement with the teeth. Disengagement of the pawls is effected by rotation of levers K about a shaft L, such rotation being derived from an upward pull on the strap P producing rotation of a lever M connected to the shaft L. Mechanism to retain the pawls in the disengaged position is housed within a box Y through which passes a sliding bar X, the projecting ends of which are attached respectively to the strap P and lever M. One edge of the bar X is notched, as shown in Fig. 5, for engagement with a member W which is mounted on the, same rocking shaft Q as a spring- pressed quadrant Z. Fig. 5 shows the position of the parts when the pawls G are disengaged, the strap P having been pulled so as to allow the tooth on the tumbler W to clear the narrow tooth T<1> on the bar X. If the strap P now be pulled sharply, the tooth on the tumbler W contacts with the wide tooth T<2> on the bar, which, however, is drawn downwards by the springs 2 sufficiently quickly to allow the tumbler tooth to pass over the narrow tooth T<1>, and thus to return the pawls G to operative position.

Abstract: 996,290. Textile treating apparatus. MASCHINENFABRIK VITS G.m.b.H. Sept. 29, 1961 [Oct. 1, 1960], No. 35269/61. Heading D1L. [Also in Division F4] In apparatus for treating fabric, plastics or paper webs, the web 1, Fig. 4, passes through a drying space 3 in a floating condition achieved by treatment air 10, Fig. 1, emerging in the form of hollow jets 11, 12 from upper and lower nozzle boxes 6 positioned in parallel transverse to the direction of movement 2 of the web, the shape of the jets being determined by baffles 13 supported by plates 14 located in slots 9 of each nozzle box 6. Each hollow jet confines a space 15 tapering in the direction of the web, which space gradually builds up a static excess pressure to provide a supporting cushion for the web due to the deflection of marginal portions 16, 17 of the jet. Opposed hollow jets are in staggered arrangement either singly or in groups which provide a slightly undulating movement to the web in the direction 2. In a modification, Fig. 6, (not shown), the undulating movement is avoided by the centre planes of the nozzle boxes 6 being perpendicular to the plane of the web but the side walls of opposed upper and lower boxes forming the nozzle stols are inclined away from the centre plane in alternate directions. In a further modification, Fig. 7, (not shown), the web is stretched in a direction perpendicular to the path of travel by hollow air jets from upper and lower nozzle boxes being directed outwards so as to hit the centre plane of the web at an acute angle. Various forms of nozzle boxes are described to achieve the hollow air jets.
