Title: Improvements in or relating to cards for use in statistical machines
IPC: G06K19/02
Filed: 1937-11-22
Abstract: 506,017. Statistical cards. BRITISH TABULATING MACHINE CO., Ltd. Nov. 22, 1937, No. 32122. Convention date, Nov, 23, 1936. [Class 106 (i)] [Also in Group VIII] A card for a statistical machine comprises two sheets of paper cut from a single web of paper having a glazed surface and secured together by adhesive with'the surfaces that constituted parts of the same glazed surface before division applied against each other. The cards may be made by cutting a spool of paper into an even number of narrow reels whose width is slightly greater than the width of the card, a pair of reels that were adjacent before division are fed to a machine in which glue is applied to the glazed surface of one reel and this surface is then pressed into contact with the glazed surface of the other reel, the sheet material so produced is then cut to size. The reels are preferably so cut that one of each pair is slightly narrower than the other and the glue is applied to the narrower reel to allow of slight misalignment of the reels. The reels are preferably stored with both ends exposed for a time before glueing to allow of their moisture contents becoming equal. Specification 383,517 is referred to.
Patent GB-1090129-A (GB)
Title: Transfer counter
IPC: G06M1/14
Filed: 1965-07-27
Abstract: 1,090,129. Counting apparatus; zeroizing. TRI-TECH Inc. July 27, 1965 [Aug. 7, 1964], No. 32145/65. Heading G4D. A transfer counter comprises a plurality of counter drums, means for operating a lower order drum, resiliently biased transfer means interconnecting said lower order drum with a higher order drum and reset means for moving said transfer means against its resilient bias, said transfer means thereupon acting on said lower order drum to reset it to an initial position. As shown, the resetting operation is initiated by first decoupling the various driving gears 53 from their corresponding drums 22, 23 and thereafter rotating the gears 53 through a small angle in a direction to urge followers 61 out of contact with cams 60. The transfer mechanisms 45 are thereupon effective to drive the drums towards the reset position through planetary gears 50, 49 and trunnions 52. Each of the gears 53 is coupled to a drum by means of a toothed wheel 65. The rotary and axial reset movement of each gear 53 and wheel 65 is controlled by reset arm 70 attached to rotatable and axially movable rod 40. As illustrated in Fig. 2 a solenoid 80 is energized to reset the counter; this moves actuating pin 82 to the left and hence pivots reset lever 85 clockwise about shaft 42. The reset lever urges a reset arm 70a and thus rod 40 axially to the right by reason of camming surface 86. The movement of rod 40 also carries with it reset arms 70 whose fingers 72, 73 engage gears 53 and move them free from their corresponding drums. As reset arm 70a completes the axial movement it rides off a boss 94 and is biased by spring 95 to move in an anticlockwise direction. This in turn rotates rod 40 and reset arms 70 whose fingers 72 rotate wheel 65 and gears 53 through a small angle. The impact of the fingers 72 rotates the gears 53 which rotate planetary gears 49, 50 and thus pinions 52 to start the drums moving towards their reset positions. The impact of fingers 72 also makes transfer arms 47 pivot against the biasing force of the springs 63 to carry followers 61 away from cams 60. The increased biasing force of each spring 63 produces a pivotal movement of transfer arms 47, Figs. 5 to 8 (not shown), such that the planetary gears 49, 50 move relative to the now stationary gears 53 and continue to rotate clockwise thereby maintaining the rapid movement of the drums. As each drum approaches its reset position follower 61 engages the lobe on the cam 60 to arrest further reset movement.

Title: An improved method of charging internal combustion engines
IPC: F02M69/00
Filed: 1936-12-28
Abstract: 492,886. Charging two- and fourstroke - cycle engines. ERREN, R. A. Dec. 28, 1936, Nos. 32508 and 32709. [Class 7 (ii)] During each charging stroke air compressed in the crank-case is fed unthrottled to the cylinder and, after closure of the exhaust and air ports 9, 10, a charge of atomized fuel and air is injected towards the ignition plug. The amount varies with the engine speed so as to produce constant final compression and stratification of the charge, an engine-driven blower 14 and valve 15 being employed. The charge may be injected through the cylinder head, mushroom valves or baffles being employed to effect lateral movement. Injection takes place during crank-shaft angular movement of not less than about 30‹, and is completed before the piston has traversed half its compression stroke. Blower pressure is at least twice that of the prevailing cylinder pressure.

IPC: F16B31/02
Filed: 1958-10-11
Abstract: 870,946. Pretensioning nuts, bolts. KELLERMANN, R. Oct. 11, 1958, No. 32531/58. Class 89(1). In limiting the tension applied to a bolt or nut during tightening thereof, two annular-axiallystepped surfaces are provided on the bolt or nut or on a washer so that when the required bolttension is reached the surfaces become co-planar and the torque applied to the nut or bolt increases suddenly. The screw may comprise an elastically-deformable-head 1, Fig. 1 having axially-stepped surfaces 6a, 6b, the head being deformed so that the surfaces become co-planar when the required bolt-tension is obtained. A washer 5 may have similar stepped surfaces 5a, 5b. The surface 6b, Fig. 1a, may be bevelled to give a gradually-increasing resistance to deformation. In another form, a socket-screw-head may be radially-split to render it elastically-deformable, or a nut 23, Fig. 3, may have an internal groove 25 for this purpose. Alternatively, elastically-deformable washers may have axiallystepped surfaces such as 66, 67, Fig. 5. The frictional-coefficient of the surface which engages first may be reduced by surface-treatment &c., so that the tightening-torque will increase more suddenly when the second surface engages.

The apparatus may comprise two concave mirrors M, M<SP>1</SP> each having an associated detector D, D<SP>-</SP> 2 movably mounted on arcuate rails I, I<SP>-</SP> respectively, so that the difference between the angles of incidence on the two mirrors is constant; the signals received by each detector are compared. Alternatively, a single concave mirror may be used either with two detectors the signals of which are compared, or with a single detector having a magnetic tape recorder so that the signal produced can later be compared with a standard.
Patent GB-429103-A (GB)
Title: Improvements in the manufacture or treatment of filaments, threads, fibres, yarns, ribbons and like materials made from or containing organic derivatives of cellulose
IPC: D06M11/38
Filed: 1933-11-22
Abstract: Organic esters of cellulose particularly in the form of filaments, threads, fibres, ribbons or like materials are saponified by means of an amine containing at least two amino groups.  Suitable amines are ethylene diamine, sym. dimethyl ethylene - diamine, mono - methyl ethylene diamine, propyl diamine, and 1, 2, 3 triamino propane.  The inclusion of a hydroxy group in the amine as in a g  diamino b hydroxy propane favours penetration of the materials by the agent. The saponification may be deep, even extending through the whole section of the materials.  The starting materials may have a basis of cellulose ester of high, low or medium viscosity, and may have a high tenacity produced by stretching as in Specifications 277,089, 323,790, [both in Class 2 (ii)], and 370,430 or by special wet spinning processes as in Specifications 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, and 378,858.  The materials may be passed as hanks supported on rotating, travelling rods through a saponification bath or may be passed continuously through the bath, e.g. in warp formation, or the materials in the form of packages may be immersed in the bath.  The materials may be under tension during the process, or there may be little or no tension to facilitate contraction, e.g. as in Specification 403,071.  Solvents, swelling agents, or latent solvents may be included in the bath. Saponification is preferably effected rapidly, e.g. in 2--5 minutes, the temperature being 70--90 DEG  C. or more, or 40--60 DEG  C. or less.  At high temperatures the measures to limit evaporative losses described in Specification 411,094 may be adopted.  In an example a hank of cellulose acetate yarn is immersed in a 20--30 per cent solution of ethylene diamine at 80--90 DEG  C. for 3--5 minutes and is then washed and dried. Cellulose acetate yarn in warp formation may be similarly treated. In another example a 15--20 per cent solution of ethylene diamine is used at 70--80 DEG  C.  Dyes may be applied in the saponifying medium.

Filed: 1947-12-12
Abstract: 653,401. X-ray apparatus. PAATERO, Y. V. Dec. 12, 1947, No. 32874. Convention date, March 19. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 5, 1948.] [Class 98 (i)] [Also in Group XIV] A dental patient's chair comprises a seat mounted on a base member for rotation without translation about a central vertical axis and for horizontal translation without rotation on each side of its central position, means for locating the head of the patient in a fixed position wherein the axis of rotation of the seat passes through the centre of curvature of the arcuate front portion of the upper and lower alveolar process of the patient, means for effecting the said rotational and translational movement of the seat, and guide surfaces on the base member co-operating with surfaces on the underside of the seat whereby on rotation and translation of the seat any point along the upper and lower alveolar process of the patient passes through or closely adjacent to a fixed point. As shown in Figs. 1, 3, a seat 6 on a foot 7 has a vertical axis of rotation 8. A plate 15 fixed beneath seat 6 slides on a plate 14 fixed to foot 7, and has pins 16, 8b, 17 running in grooves 19, 18, 20. The edge of plate 15 is toothed and engages a toothed wheel 21 driven by a hand crank or an electric motor. The grooves are shaped as shown so that the seat is guided to move first in a straight line, then to rotate about axis 8, and then to move in a straight line again. The back 9 of the chair carries a skull cap 11 and neck rest 10 which are adjustable to hold the patient's head in such a position that the axis 8 passes through the centre of curvature of the front part of the alveolar process. This adjustment is effected with the help of a pivoted arm 12 with an extension 13, the end 8a of which lies on the axis 8, the arm 12 being afterwards removed. When the seat is moved, the patient's teeth will pass in succession a fixed point at which an X-ray tube is placed, so that the X-rays fall perpendicularly on each section in turn of the alveolar process. The Specification as open to inspection under Sect. 91 also describes a diaphragm for the X-ray tube having a slit limiting the X-rays to a vertical fan-shaped beam, and refers to an X-ray film of part-annular shape which is placed behind the teeth. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to hack-saw machines
IPC: B23D49/00
Filed: 1937-11-30
Abstract: 506,592. Reciprocating saws. NEILL & CO. (SHEFFIELD), Ltd., J., SWAIN, G., and BOWER, W. L. Nov. 30, 1937, No. 33016. [Class 145 (ii)] In a hack-saw machine, the blade is supported against bending in its own plane by a narrow support against which the back of the saw reciprocates; the guide support and the saw are fed in steps by irreversible mechanism at the end of each idle stroke and the line of the teeth is inclined to the back to ensure cutting during the whole of the forward movement. The saw 24, Figs. 1 and 3, is carried in a frame 16 which is reciprocated by the crank arm 51 and is guided by an arm 17 pivoted at one end to the frame of the machine, the other end being moved downwardly in steps by the feed mechanism. The saw is supported against bending in its own plane by a non-reciprocating plate 18 against which it works, this plate being mounted in a frame 20 bolted to the arms 17 and having lugs 19 which bear against the sides of the saw. The thickness of the plate 20 is less than the width of the cut so that it can follow the saw without binding. The feed mechanism, shown also in Fig. 4, is operated at the end of each idle stroke by an arm 46 mounted on shaft 45 and oscillated by linkwork from a cam 50 on the driving shaft. The arm 54 on shaft 45 rotates the outer nut 40 in the casing at the end of the working stroke so as to raise the central screw 31 and lever 17, to which the screw is connected, during the idle return stroke of the saw. The nut 40 is returned by an adjustable spring. At the beginning of the working stroke, arm 64 similarly rotates collar 58 which acts through friction clutch discs 59 to rotate the long nut 80 and feed screw 31 and arm 17 downwards. Rotation of the long nut 80 backwards is prevented by a ratchet and pawl. Return of collar 58 is also effected by an adjustable spring. Screw 31 may be rotated by handle 35 and bevel gearing to raise and lower the lever 17 quickly, the handle and screw being normally locked.
