IPC: B60S1/10
Filed: 1954-02-24
Abstract: 763,845. Semi-rotary engines. O'SHEI, W. E. Feb. 24, 1955 [Feb. 24, 1954], No. 5513/54. Class 110 (2). A suction motor, for use in actuating a windscreen wiper blade, has the usual " pickervalve " mechanism 3, but the ports 5a, 5b, 5c are longer in the radial direction than normal to give increased areas of the ports and thus reduce the frictional effects of fluid flow therethrough, without reducing the spacing between the ports. Preferably the ports are trapezoidal or rectangular in shape. The passages leading from the ports to opposite sides of the paddle chamber 1 are also of larger size than normal. A semi-rotary manual valve 12, preferably of flexible material, is provided on the underside, Fig. 5, with recesses 12a, 12b for coaction with ports 10a, 10b, 10c, 10d, 10e on the circular valve seating and a port 15 through which the suction-connector 14 acts. A port 16 is vented to atmosphere through a hole 19. The valve 12 is actuated by a disc 17 having recesses 17a which engage embossments 17b on the valve. The disc is moved by a finger 20, limited by the ends of a slot 21, or if the disc is inverted, by the ends of a slot 22. The manual valve is used to start the motor by connecting the suction and atmosphere. When the valve is in the position with the extension 12c overlying the port 10a, the source of suction will be connected through the port 15 and the passage 12b and extension 12c to the automatic valve and the ports 10b, 10c connected to opposite sides of the automatic valve, will be connected by arcuate passages 12a to the ports 10e, 10d, respectively. When the valve 12 is turned so that the extension 12c lies intermediate a pair of ports 10a and 10b, or 10a and 10c, the source of suction will be disconnected from the automatic valve and will be applied through the extension 12d to one or other of the ports 10d or 10c so as to park the paddle 26 at one end or the other of the working chamber. The other port 10e, or 10d, which is not connected to the source of suction, is connected to atmosphere through a passage 12a and the vent 16. Specifications 672,678, 672,680 and 691,483 are referred to.

Abstract: Compositions of matter such as coating compositions, moulding compositions, filaments, films and sheets and rods contain a cellulose derivative and triphenylacetin.  Other plasticizers may be employed in conjunction with the triphenylacetin.  Tapes, ribbons, fabrics or insulated cables may be coated or impregnated with such compositions.  Examples of suitable solvents for liquid compositions are acetone, alcohol, benzene, dioxane, ethyl lactate and methyl or ethyl glycol mono-acetates.  Natural, semi-synthetic, or synthetic resins may be included in the compositions.  If a material is to be impregnated with a composition, precautions should be taken to avoid deleterious action on the material by substances present in the composition. Thus a tape having a basis of cellulose acetate may be coated with an ethyl cellulose composition in a medium which is not a solvent for the cellulose acetate.  The composition may be employed in conjunction with other coatings.  Suitable compositions are cellulose acetate 100 parts, triphenylacetin 160 or 230 parts; cellulose acetate 100 parts, triphenylacetin 120, 50 or 60 parts and isomeric xylene mono-methyl sulphonamides 15--30, 90, or 60 parts respectively; cellulose acetate 100 parts, triphenylacetin 140 parts, and dibutyl tartrate 45 parts; and ethylcellulose 100 parts with triphenylacetin 85 parts.  A suitable solvent medium, if these compositions are to be applied in solution, consists of about 40 parts of acetone, 160--180 parts of alcohol, and 240--220 parts of benzene per 100 parts of cellulose derivative.

Abstract: 1337886 Program controlled manipulators AMF Inc 8 Feb 1972 [26 March 1971] 5894/72 Heading G3N A mechanical handling device of the industrial robot type is controlled by pre-programmed magnetic tapes. A cycle of digital positioning signals and coded commands is recorded on a first tape which is then used to record the cycle successively a number of times on a second tape. The second tape may then be copied on to a third tape, so that both tapes can be loaded on to decks and used alternately to control the handling device which thus cycles indefinitely without interruption. In the arrangement shown, a handling device 10 includes a column 11, arm 15 and carriage 16 each with an associated servosystem con-- trolled by a lever 60. Grippers 18 and a wristlike joint 19 operate stepwise in response to command signals generated by a plug board 65 each time a switch 61 is depressed. In a first mode of operation, the device 10 is manually controlled by the lever 60 while a tape is advanced on deck A. The positions of members 11,15, 16 are represented by voltages taken off potentiometers and connected through A-to-D converters to a head 36 which records the signals on separate tracks. Command signals from the plugboard 65 are also recorded on a further track on the tape. When the cycle is complete, the tape is rewound and selector switch 66 moved to the copy mode. The cycle is now copied repeatedly on to a second tape mounted on deck B, with automatic rewind of the original tape at the end of each cycle. A third tape is produced from the second tape, so that two tapes are available each with the operating cycle recorded a number of times. These tapes are loaded on to decks A, B and control the device 10 when the switch 66 is appropriately set. When one tape has run through, it is automatically rewound while the other tape controls the machine. Photo-electric sensors 39, 40 detect translucent leaders on the tapes to indicate the rewound condition. Logic and control circuits are described, Figs.2-6 (not shown).
