Abstract: 981,457. Ring-spinning apparatus. O. KONING. Dec. 4, 1961 [Dec. 2, 1960], No. 43362/61. Heading D1D. A textile spinning-ring has an internal face constituting a track for a traveller, all sections of the face perpendicular to the axis of the ring being circles and all sections of the face on axial planes being concave. In Fig. 2, the ring comprises an annulus 20 with an inwardly-directed flange 21 providing a track 33 which is a zone of a sphere of which the centre is at M1 which is on the axis b, b of the ring e.g. at a point below the central plane cc of the track, preferably on the plane of the lower edge of the track. The parts 20, 21 may be wholly or partly of material e.g. steel or aluminium alloy which is a good heat conductor and has a low friction-coefficient, while the ring and its support may be cooled by fins, coolant or the Pettier effect. The traveller, which may be of steel, brass, nylon or "Teflon" (Registered Trade Mark), or a material hard enough to destroy lint &c. and thus, (it is stated) create a lubricating film,is substantiallyU-shaped with legs bent as shown to provide shoulders 34,35, the central sliding portion 33 being of smaller height than the track and corresponding in shape to the concavity of the track or being such as to assume such a shape by wear or deformation. The sliding portion also, may be an insert of steel nylon or teflon. In order to limit displacement of the ring, one or more annular elements 28, 29 of low-friction, high resilience and wear-resistance are provided in grooves in the upper and lower falls of the flange. In another form of ring, the concavity of the track has a radius of curvature smaller than the radius of the track itself and the track is provided with grooves for lubrication which improve the stability of the traveller.

Title: Computing machine
Inventor: CROWTHER GERALD OFFLEY
IPC: G06F7/50
Filed: 1963-11-12
Abstract: 1,098,853. Electronic calculators. MULLARD Ltd. Feb. 11, 1965 [Nov. 12, 1963], No. 44646/63. Heading G4A. An electronic calculator comprises a keyboard for inserting a first number into an electronic input store with decimal point information, information derived from the input store being transmitted with automatic correct alignment of decimal points, to an electronic accumulator. The calculator is effective to multiply a multiplicand registered in the input store by a multiplier whose digits are entered successively in the keyboard, which has ten digit keys 0-9, the result being built up in the accumulator. In the calculator described the input store and the accumulator each comprise six decimal multicathode counting tubes. In operation for multiplication, the multiplicand is entered digit by digit on the keyboard, commencing with the most significant digit, a control chain IC, Fig. 3, of trigger tubes being stepped on by one place for each digit entered, the digits being registered in successive counting tubes of an input store IS. Operation of a decimal point key causes a pulse to be applied on a line DPP to all the trigger tubes in a decimal point store IDPS, that tube which is biased by the conducting tube in the chain IC being fired to make the decimal point. The MULTIPLY key is now depressed and the multiplier entered digit-by-digit in the keyboard. Depression of the digit key corresponding to the first multiplier digit causes the multiplicand to be added a corresponding number of times into the accumulator, the first addition causing the accumulator decimal point store to register the position of the decimal point in the accumulator. The fired tube in the accumulator decimal point store primes a corresponding tube in the input control chain IC and the fired tube in the input decimal point store IDPS primes a corresponding tube in an output control chain OC as shown schematically in Fig. 2. To control the addition of a digit in the input store IS into the accumulator store AS, the fired tubes in the output control OC and input control IC are effective to select respectively the counter tube in the input store IS to transmit a digit and the counter tube in the accumulator store AS to receive a digit. The transfer is effected by applying a cycle of ten pulses to the selected tube in the store IS. Both control chains IC and OC are now stepped on by one to control addition of the next lower digit. Addition in this manner of the contents of the input store into the accumulator takes place a number of times equal to the value of the current multiplier digit. When the next multiplier digit is entered, the decimal point in the accumulator store is shifted one place to the right before any further addition takes place. At the conclusion of the multiplication operation, the accumulator AS contains the six most significant digits of the product, the decimal point being registered at the correct place in the decimal point store.
