Abstract: 517,375. Braking. BELL, W. T., and PERRY, F. B. June 24; 1938, No. 18773. [Class 78 (v)] In mechanism for applying a brake lightly to a winding engine during its period of high speed, and heavily near the. ends of a wind, a cam, rotating once for each complete wind, is provided to form a positive stop to the brakeapplying device during this high-speed period. A fluid-pressure valve 8a, mounted on a stem 8 fitted with guide pistons 8b, 8c, controls the admission of steam &c. from a supply duct 1c to the engine pipe 1a, the brake being adapted to be "on" when fluid pressure is removed from the engine. The. top of the stem 8 is connected by a link 9 to a rocking lever 10, the further end of the lever 10 being coupled by a link 12 to a crank 13 unitary with a handle 15. Movement of the handle 15 will bring the valve 8a to either side of the port 5, thus connecting the engine either to supply or to exhaust, but mechanism is provided whereby full opening to exhaust, and consequently full application of the brake, cannot be effected during the middle traverse of the wind, when the speed is greatest. This mechanism comprises a cam 17 rotating once for each wind, and having bearing thereon the roller 19a of a bell-crank 19, 23 linked to the end 10b of lever 10. The cam 17 is so shaped as to permit adequate lowering of the stem 8 at each end of the wind to permit the engine to exhaust fully and so apply maximum braking power, while at the middle of the wind pre-' venting such full lowering of the stem 8. Complete " off " position of the brake is allowed at any time, the roller 19a then moving out from contact with the cam 17. When applied to a double drum winder, in which both drums are generally clutched together with their loads balancing, but which can be de-clutched for separate operation of a single drum, a second cam 16 is provided on the cam shaft 18. The bell-crank 19, 23 can be shifted laterally in consonanoe with the drum clutch to engage either cam 16 or 17, and the cam 16 is made larger as less braking power is normally required with balanced drums.

Title: Improvements in or relating to devices for registering coded information
IPC: G11C11/22
Filed: 1954-06-30
Abstract: 753,944. Electric digital-data-storage apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 30, 1954 [July 3, 1953], No. 19175/54. Class 106 (1). A trigger element comprising a capacitor of high remanence is characterized in that it is so coupled with a second capacitor and an output impedance that pulses applied simultaneously to the two capacitors produce a difference signal across the output impedance, which difference is substantially zero when the first-mentioned capacitor is in a particular one of its two possible conditions of remanence. The " reading " of the trigger is thus reduced to determining whether or not, as the result of applied " read " pulses, a voltage is developed across the output impedance. A capacitor of high remanence Cd, Fig. 3, having a characteristic curve as in Fig. 2, is coupled with a second capacitor Co to an output load consisting of a capacitor C shunted by a resistance R. The capacity of Cc is chosen equal to the slope of the characteristic curve between the points Q1 and D. Thus, if Cd is in condition Q1, representing a " O," and equal positive and negative pulses are applied at terminals Al and A2 respectively Cd will appear to have a capacity equal to the slope of Q1D (since Cd is assumed to be in state Ql initially) which, by choice, is the same as the capacity of Cc, and therefore no voltage will be developed across the output load. However, when Cd is in the state Q2, representing a " 1," it will appear, to an applied " reading pulse, to have a capacity equal to the slope Q2D, which is larger than the capacity chosen for Cc and therefore a positive output pulse appears across the output impedance at B. In a second embodiment the output load is the primary of a transformer, with an earthed centre tap, the output pulses being taken from its secondary. In a third embodiment, to ensure that capacitor Cc does have the desired capacity, it is constructed from the same slab of dielectric as Cd, there being a common electrode for Cc and Cd.

[Also in Division F2] In an arrangement for lubricating the screw and rack of machine tools, pressurized lubricant is supplied to the flanks of the thread of the screw through passages therein; however, only the flanks of the thread of the screw which are in engagement with the rack are supplied with lubricant and, according to the direction of axial loading, only the flanks of the thread which oppose said axial loading are supplied with pressurized lubricant. A screw 1, Figs. 1 and 3 (not shown), is in engagement with a rack 2 and has radial passages 62a, 61a and 62b, 61b connecting respectively with axial passages 57a and 57b which lead to passages 53a and 53b each individual passage of which opens out on a right or left-hand flank of the thread of the screw 1. Pressurized lubricant is supplied through pipe 74, connection 73, pipe 72, connection 71 and through a passage 88 in member 83 to a distributer 65a mounted therein. The distributer 65a has a radial passage 87, an interconnecting axial passage 67 and radial passages 68, 69 which, according to the axial position of the distributer, connect with either passages 62a or 62b. The distributer 65a is actuated, according to the direction of rotation of the screw, by supplying hydraulic pressure to either side of a piston 91, which is integral with the distributer 65a and is mounted in a bore 92 of the member 83. In use, according to the position of an electrically operated valve 98, pressurized fluid passes through either conduits 96 or 97 to actuate the piston 91 and consequently position the distributer 65a so as to supply either the left or right hand flanks of the thread of the screw with pressurized lubricant so as to oppose axial thrust applied thereto. A small quantity of pressurized lubricant is allowed to escape to the flanks of the thread not opposing the axial load.
