IPC: B41B27/00
Filed: 1967-12-28
Abstract: 1,250,880. Type-composing machines. INTERNATIONAL PHOTON CORP. 18 Dec., 1968 [28 Dec., 1967], No. 58756/67. Heading B6W. A photographic type-composing machine comprises a keyboard, means for selecting a point size, means for selecting a pre-determined length of line in absolute units, and means for automatically dividing the line length by a value which is a factor of the point size whereby the quotient of the division represents the length of line in relative units of character width. Fig. 1 illustrates apparatus in which actuation of a key on keyboard 2 causes a signal from a character width store 4 to be entered into an accumulator 6 which operates in relative units of width and which is set to the required line length in relative units and provides a warning signal 12 when a line is nearly complete, for justification purposes. Changes in point size are accompanied by a change in the number of relative units of width which can be accommodated in any given line length and the remainder of the apparatus is concerned with feeding automatically the length of line desired, in relative units, into the accumulator in response to operation of pointsize and absolute line length controls 16, 14. The quotient counter 30 stores signals corresponding to the number of times the absolute line length value in accumulator 24 can be divided by the point-size value in register 28, the division being performed by repetitive addition. The quotient is transferred to a tape punch control 40, and to the character width accumulator 6. A second embodiment, Fig. 2 (not shown) provides for the production of condensed type by incorporating a set selection switch in the point-size circuit.

Abstract: 1,251,205. Pipe couplings; pipes; joint making packing. DUNLOP HOLDINGS Ltd. 2 April, 1969 [2 April, 1968], No. 15704/68. Headings F2B, F2G and F2P. A pipe assembly comprises two pipe lengths 7 coupled together at adjacent ends, each length having an elastomer lining 6, which extends around the said adjacent end and folds back over the external surface of the pipe length, and carrying a dished coupling member 11. The coupling members together provide a channel between them in which lies an annular sealing member and are held together, e.g. by bolts, so that the sealing member is pressed against the folded back portions of the linings to provide a fluid-tight seal between the pipe lengths. As shown in Fig. 4, the pipe lengths comprise a fibreglass-resin outer shell 7 and the coupling members are moulded from fibreglass-polyester resin, the channel for the sealing member 15 being V-shaped. In modifications, the sealing member (a) is triangular in cross-section, (b) comprises two annular components frustotriangular in cross-section, (c) is formed by two components each comprising an annular element 27, Fig. 10, rectangular in crosssection housed in an annular element 23 U-shaped in cross-section and having an integral flange 24, the abutting faces of the rectangular elements being concave, and (d) consists of two components each triangular in cross-section and having curved contacting faces. There may be a gap between the linings, and the sealing member may be adhesively secured to the linings. The coupling members may, alternatively comprise stub flanges having steel backing plates.

Abstract: 1,252,663. Cutting tools. VALERON CORP. 13 Jan., 1969 [15 Jan., 1968], No. 1875/69. Heading B3T. A cutting tool having a flat polygonal insert 18 which is clampable in seating on a tool holder by a pin 50 which engages in a hole 20 in the insert is provided with engageable groove and shoulder 60, 38, on the insert and holder seat, respectively, to prevent movement of the insert relative to the seat when the tool is in use. The groove on the insert is constituted by a flat land 60 whose angle of inclination to the top surface of the insert is opposite to the inclination of the insert side walls. The clamping action of the pin 50, which is of the deflectable head type, urges the land 60 into engagement with the shoulder 38 on the holder. The plane containing the force exerted by the pin head is nearer the base 30 of the seating than the reactive force produced by the engagement between the land and shoulder and this in relation to the inclination of the land produces force components parallel to and normal to the seat whereby the insert is urged into abutment with the seat.

Filed: 1969-12-01
Abstract: 1289692 Data transfer BURROUGHS CORP 1 Dec 1969 58659/69 Heading G4A A communications module adapted to control data transfers on several input/output channels in a system having a main memory includes a local memory for storing a channel descriptor for each channel and having a data buffer, a control unit coupled to the local memory and being operative to scan the channels at least once each in each cycle and transfer data bytes into and out of the local memory, a main memory interface control for transferring the descriptors and data words from the main memory to the appropriate locations in the local memory and status descriptors and data words from the local to the main memory, and a local memory controller for alternately granting local memory access to the control unit and the interface control for interlacing the transfer of data bytes on successive channels and the transfer of descriptors and data words to and from the main memory. In operation channel descriptors are transmitted from field 51 in the main memory 50 to field 71 in a data demand module associated with the input/output channels., On detection of a flag signal from a scanned channel on input 93. The control unit 80 withdraws the appropriate descriptor over path 81, withdraws the appropriate data word over path 82, transfers a data item, decrements the descriptor, and returns it to field 71 unless this completes the transfer of a word or a block of data. In either of the latter events the descriptor and the data are placed in memory stack 75. If a large number of lines require this service at any one time stack 75 overflows and the condition is treated as an error. When a channel flag indicates that the channel requires service the time available is divided between transfers of data and descriptors from the main memory and data to the main memory. However if when scanned a channel does not require service the allotted time is used entirely for the transfer of descriptors from the main memory.

Abstract: 1290155 Strain gauge UNITED KINGDOM ATOMIC ENERGY AUTHORITY 20 Oct 1970 [24 Oct 1969] 52358/69 Heading G1M A spring pressed needle 6 in a conduit body 1 has a tapered nose 7 which in operation throttles an orifice in a fixed member 4 and contacts an object the strain in which moves the needle axially. The needle which has the cross-section shown in Fig. 2, slides in a sprung bush 10 and is displaced by varying amounts for calibration, so that gas flowed thro the body from a gas supply on the left to the space 18 on the right has its pressure measured at three positions, P 1 , P 2  and P 3  by means of pressure tappings 13, 14 and 15. These values of P 2  are plotted against the known axial displacements of the needle while throttling and adjusting pressures P 1  and P 3  to predetermined values, to form a calibration chart which is peculiar to the gauge and so on being tested. In use after calibration the nose portion 7 abuts a surface of the object and the strain is measured by relating the needle movements to the calibrated pressures. The temperature of the gauge may be controlled by a surrounding electrical heating circuit.

The system includes a manual valve 5 and automatic shift valves 6, 7 responsive to governor pressure 11 and throttle pressure 16.

Other specified volatile plasticizers are xylene, trichloroethylene, perchloroethylene, carbon tetrachloride, ethyl alcohol, isopropyl alcohol or butyl alcohol. In modifications, either an adhesive layer is applied to the compressed foam surface 12 and the tape 14 and the foam 15 with or without the layer 13 are applied thereafter or the joining of the abutting edges is effected by sewing.
