Abstract: 859,421. Ingot-strippers. DEMAG A.G. April 14, 1958 [April 13, 1957], No. 11762/58. Class 83 (1). An ingot-stripper comprises one pair of tongs 9 by which the moulds are held inposition, and another pair of tongs 3 by which the ingot is gripped, and a means controlled by the stripper-plunger 11 which, as the plunger is raised, raises the shield 7 of the ingot-gripping tongs to close them, and when the tongs have closed, takes part in the upward movement of the shield and acts upon the mould-tongs to open them when the ingot has been released. The stripper-plunger 11 has a catch 11a, whose projecting ends engage the guide-tube 12 of the tong-shield 7 and raise it when the stripperplunger is raised. ; Upon closing of the tongjaws 3, their cross-bar 4 is also taken along by the upwardly-moving shield 7, and after a predetermined travel engages means 13 to open the mould-tongs. The mould-tongs are re-closed by means 14 carried on a tube 15, which is raised when the tube 12, in its upwardmovement, engages a flange 15a and carries it upwardly.

A circularly woven textile structure incorporating a metallic reinforcement 3 in the form of a helical weft is coated with a cellular foam 4 having closed cells, the outer surface 5 being smooth and continuous and the coating adhering to the structure through the medium of burst open cells and not through a continuous layer of closed cells. The textile structure is composed of longitudinal warp threads 1 and helical weft threads 2 and may be of cotton, hemp, jute or glass. The reinforcement 3 may alternate with the weft 2 and may consist of iron, steel, brass or aluminium wire which is rustless or plated to prevent rusting. The coating 4 is a thick, cellular foam layer of natural or synthetic rubber, a derivative of synthetic rubber, polyvinyl chloride or other synthetic resin which is applied by dipping the textile structure in a coating bath or by spraying. Preferably, the coating 4 is extended at 7 around the end faces of the pipe and at 8 along the inner surface of the structure 1,2 and is approximately 3 millimetres in radial thickness for a pipe having an outside diameter of 75-80 millimetres. The bursting of the cells of the coating in contact with the structure 1, 2 is dependent upon the surface tension of the coating liquid, its wettability and the roughness of the textile structure. The finished pipe is stated to be fluid-tight and insulated against heat and sound transmission and may be used for air-conditioning pipes in motor vehicles and living quarters and to withstand temperatures from-40‹C. to 150‹C.

Title: Improvements in or relating to decimal-point indicators for calculating machines
IPC: G06F7/491
Filed: 1959-04-14
Abstract: 914,330. Calculating-apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 14, 1959 [April 14, 1958], No. 12624/59. Class 106 (1). A desk-calculating machine is provided with means for indicating the position of the decimal point in the result. The invention is applied to a machine for the four rules having an output register I and an input register II divided into two parts a and b. Multiplication is by repeated addition and division by repeated addition of complements, the means employed not being described in detail. The possible interdigital positions of the decimal point are referenced- 61 ...  - 2<SP>1</SP>, - 1<SP>1</SP>, 0<SP>1</SP>, 1<SP>1</SP>. . ., 9<SP>1</SP>, and a decimal point indicator KA, Fig. 8, is connected to the various outputs 21-36 of a ring counter SR. For addition and subtraction, a button C is depressed initially to set the decimal point to the position 0<SP>1</SP>. The registers I, II are zeroized and the first number in the arithmetic operation is set in the register II. An " add " button is then depressed, to close a switch O, Fig. 8, and transfer the number from the register II to the register I. To place a decimal point in point position i<SP>1</SP> (i = 0, ..., 9), a key Ti is depressed thereby supplying i pulses from a pulse generator PG over contacts C<SP>1</SP>i, switch O, and lead 19 to the ring counter SR to move the point i places to the right to the position i<SP>1</SP>. For multiplication the two factors are written in the parts a and b of the register II (see Fig. 4a), the button C is depressed to the set, the decimal point to the position 0<SP>1</SP>, the " multiply " button is depressed to close a switch V and cause the product to appear in the register I, Fig. 4b. Keys T0-T9 relating to the points in the factors are then depressed, the pulse generator PG supplying pulses over the actuated contacts C<SP>11</SP> 0 -C<SP>11</SP> 9  and line 19 to position the point correctly in the product, Fig. 4c. For division, the dividend with its decimal point is entered in the register I, as described for addition. The divisor is then entered in the part a of the register II and the " divide " button depressed to close a switch D and cause the quotient and remainder to appear in the register I. The key T0-T9 relating to the point in the divisor is then depressed, the ring counter SR is then stepped to right, Fig. 8, sufficient to effect the required left shift of the decimal point.

IPC: F16J9/00
Filed: 1917-09-04
Abstract: 121,974. Woodvine, G. Sept. 4, 1917. Rings.-A split packing- ring is stretched along the inner or outer surface by means of a mandrel or die carrying teeth or balls the projection of which increases gradually from the part bearing on the cut in the packing-ring to the diametrically opposite part. In apparatus for expanding piston rings a number of rings B placed in a holder A and secured by a cover plate C are stretched by forcing a mandrel D through them. The mandrel has an eccentric groove H in which balls J are secured by a cap E. Alternatively, the balls may be replaced bv teeth, either varying in height or secured in recesses of varying depth. Apparatus for treating contracting split rings consists of a holder on which the rings are secured by a cover-plate, and a hollow die with balls or teeth projecting internally.

Title: Data storage system
IPC: G11B20/10
Filed: 1974-03-21
Abstract: 1455508 Data storage systems INTERNATIONAL BUSINESS MACHINES CORP 21 March 1974 [13 April 1973] 12718/74 Heading G4C Variable length data records are stored on a fixed length format data storage medium, e.g. along tracks on a magnetic disc, under the control of a control unit, the arrangement being such that non-significant " padding " data are recorded on the medium to fill the remainder of a partially occupied track following the data recorded in the track independently of the control unit. The arrangement relieves the control unit of the task of filling a track with padding and frees it to undertake further jobs, e.g. in connection with other data stores which it controls. A magnetic disc file is described in some detail and includes a stack of discs including a servo disc providing clock signals except at an index point defining the start of a track. The pulses from the servo disc are counted to enable sectors along the tracks to be accessed by comparing the count with a required sector address, the count being reset when the index point is detected. The pulses are also used to control track acquisition, clocking etc. The control unit sends a 5-bit tag which is decoded by the file to provide one of thirteen outputs to enable various hardware units to respond to some or all of 7 bits sent by the control unit to cause an addressed file to respond, to load details of a required address into the selected file, to select an appropriate read/write head in the selected file, to cause the selected file to send data or status data to the control unit &c. Circuits are described, Figs. 3, 4, and 6 (not shown) which, during a write operation in which data supplied by the control unit are written in response to a control signal from the control unit, respond to the termination of the control signal to connect an oscillator to the appropriate write head to fill the remainder of the track, up to the index point, with non- significant, generally zero representing, data.
