Title: The process of continuously producing ground workpieces and a centerless grinding machine
IPC: B24B5/18
Filed: 1956-05-11
Abstract: 797,569. Centerless grinding. CINCINNATI MILLING MACHINE CO. May 11, 1956 [Aug. 8, 1955], No. 14694/56. Class 60. Workpieces 66 having short axial dimensions in relation to their diameters are ground in a centerless grinding machine by sequentially introducing them axially into the throat of the machine and retarding their progress through the machine by a control wheel 39 which has a diminishing diameter from front to rear and imparts a decreasing rate of feed and rotation to the individual workpieces as they advance from one end of the throat to the other and so ensures that they maintain a compact relation during the grinding operation. The control wheel is mounted in a head 37 adjustable about a horizontal axis 36 in a housing 32 which is adjustable to and from the cylindrical grinding wheel 13 along ways 31 on a slide 20 arranged to be similarly adjustable along ways 19 on a slide 16 mounted for angular adjustment about a vertical pivot 15. A work support blade 27 is mounted for adjustment about a vertical pivot 25 on the slide 20. The control wheel 39 is arranged adjacent the grinding wheel so as to provide a throat between them of uniform width and its axis is suitably inclined to the axis of the grinding wheel to provide the axial feed of the workpieces. A diamond 54 for shaping the control wheel to the desired form is carried by a holder 50 in a bore 49 in a head 45 which can be traversed by a feed screw 46 along guides 44 in a track member 43 having a central bearing hub 42 on its underside whereby it may be swivelled in a socket 41 in the upper portion 40 of the head 37 ; the holder 50 is movable in the bore 49 so that, during a shaping operation, it is urged towards the wheel 39 by a spring 52. During its shaping traverse along the length of the wheel 39 by actuation of the feed screw 46, the position of the holder in the bore 49 is controlled by a guide bar 63 which is mounted at any selected inclination on end supports 58, 59 carried by the track member 43 and engages a pin 65 projecting transversely from the holder 50. The diamond 54 is offset a distance from the axis of the holder 50 equal to the height H, (i.e., the distance the point of engagement of the workpiece 66 with the wheel 39 is above the plane containing the axes of the wheels 13, 39), the angle A of inclination of the track member 43 in its socket 41 is set to equal the angle to which the axis of the wheel 39 is tilted about the pivot 36, and the guide bar 63 is inclined at an angle B corresponding to the tilt in a horizontal plane of the axis of the wheel 39. Formulae are given relating workpiece feed rates, speed, width and end diameters of the wheel 39, the height H and angles A, B.

Title: Improvements relating to preformed beams for floors, roofs and the like
IPC: E04B5/23
Filed: 1943-09-13
Abstract: 572,522. Beams. MORTON, B. Sept. 13, 1943, No. 14962. [Class 20 (iv)] [Also in Group V] A preformed-beam for floors, roofs and the like, of the kind having side portions shaped to constitute structural ribs with rebated, recessed or splayed outer side faces, is characterized in that a portion of its reinforcement projects through the side faces from the tension flange or web and extends upwardly to or beyond the compression area, in such manner that when two such beams abut side by side and grouting is applied to the groove between them, the grouting will flow around the projecting reinforcements. In one construction, Fig. 2, the beams are of hollow box section and have inclined sides 1 and 2 terminating in base flange 3. Each beam has longitudinal reinforcements 4 and spaced transverse reinforcements 5, the latter being of inverted U form with their upper portions extending through the upper flanges 6 of the beams and their sides projecting into the grooves formed between the sides I, 2. In modifications the sides of the beams incline in the opposite direction to that shown or are parallel, and in other modifications the loops 7 of the transverse reinforcements are tied together or, alternatively, are shaped so that they intermesh with those of adjacent beams so that a longitudinal reinforcing rod can be threaded through the loops. In another construction, Fig. 6, the transverse reinforcing rods are looped at 10 to transverse rods 11 which are' embedded in a concrete or other covering material moulded on to the beams. In a modification the transverse rods are of the form shown in Fig. 2, but have their upper portions extending in the concrete floor covering and not through the beam flanges 6. The transverse reinforcing wires may be arranged at right angles to the axis of the beam or at an inclination thereto, and' may be disposed vertically or in an inclined plane. As shown in Fig. 13, the mould used in forming the beam may have inserts 16 formed with spaced projections 12, the spaces between which receive the protruding wires. In a modification, Fig. 14, the wall of the mould has recesses for receiving the wires 5, the recesses being normally closed by the spring jaws 14 of clips 13.

Title: Improvements in and connected with rubber sponges
IPC: C08J9/00
Filed: 1919-06-14
Abstract: 151,084. Beldam, G. W., and Ryall, A. U. B. June 14, 1919. Sponge substitutes.-Rubber sponges are formed so as to have large and small pores in different parts of the sponge, either by vulcanizing together superposed layers of two different compounds which will yield on vulcanization portions having large and small pores, or layers of the same compound, one part of which has been masticated more than the other and forms larger pores on vulcanization. Alternatively, a mixture of the two compounds is vulcanized while supported in a, shallow vessel of water with its lower part dipping into or just above the water. A compound whch yields, on vulcanization, small pores, consists of para rubber, milk of sulphur, lithopone, crimson sulphide of antimony, or vermilion, ceresin wax, fine oil, together with ammonium carbonate or amyl acetate. In a compound for yielding large pores, larger proportions of ammonium carbonate or amyl acetate ara used, precipitated chalk and zinc oxide are used in place of lithopone, and turpantine may partially replace fine oil.

Abstract: 1,136,506. Cathode-ray tube displays. ENGLISH ELECTRIC CO. Ltd. 5 April, 1966 [9 April, 1965], No. 15203/65. Heading H4T. A cathode - ray tube display of the value of a plurality of variables is produced by deriving voltages representative of each variable from a corresponding plurality of potentiometers 1(2) ... 1(45) and after D.C. amplification producing, via respective discriminators 3(2) ... 3(45) supplied in common with a ramp voltage from generator 5, pulses of constant amplitude and of a duration proportional to the D.C. input voltage such pulses being supplied via respective gates 6(2).. . 6(45) opened in sequence by a shift register 7 to a beam brightening circuit to bright-up the beam of tube 14 scanned vertically by the ramp voltage and horizontally by a generator 11 triggered by the last stage of the shift register. The display thus comprises a plurality of horizontally spaced vertical traces (scanned downwardly from the top of the screen) the visible lengths of which are indicative of the value of the variables. The sensitivity of the display may be increased by means of switch 13 which operates to increase the gain of the vertical deflection amplifier 9 by a factor of five and by simultaneously increasing the period of ramp generator 5 by a factor of five (e.g. from 160 to 800 microseconds). A calibration voltage representative of a predetermined value and derived by means including an adjustable calibrated potentiometer 12 produces visible vertical lines flanking those indicative of the variables so that the lengths of a selected one of the latter may be determined by aligning a cursor on the tube face with such selected line and then adjusting potentiometer 12 until the calibration lines are also aligned. The invention, which is particularly described in connection with monitoring the positions of the control rods in a nuclear reactor, the potentiometers 1(2) . . . 1(45) being operated by the rod drive mechanisms, is stated to be of wider application one other of which is providing a display of the loads on pneumatic jacks at the coal face of a colliery.

Title: Improvements in automatic voltage regulators
IPC: G05F3/18
Filed: 1958-05-13
Abstract: 862,728. Automatic voltage control systems. FOSTER TRANSFORMERS Ltd., and JENNINGS, R. E. May 7, 1959 [May 13, 1958], No. 15292/58. Class 38 (4). In an automatic control system for a voltage regulator a control signal is derived dependent on the sum of a signal proportional to the R.M.S. value of the output voltage and a signal proportional to the mean square of the sum of the lower order harmonics. As shown, a regulated voltage I is applied to a primary of a transformer 1 and a voltage across a secondary 2, through a band-pass filter 4-7, is applied to a resistor 8 and a voltage across a secondary 3, through a band-elimination filter 10-15, is applied to a resistor 16. The filters are centred at the fundamental frequency of the regulated voltage so that a voltage E 1  developed across the resistor 8 is proportional to the fundamental component of the regulated voltage I and a voltage E H  across the resistor 16 is dependent on the harmonic content. The voltage E H  is rectified by a full-wave rectifier 17 and applied to a series combination of a zener diode 18 and a resistor 19 arranged so that the voltage across the resistor is proportional to the square of the rectified voltage E H . A control voltage O, the sum of the voltage across resistor 19 and a voltage across a rectifier 9, is compared in a bridge circuit with a reference voltage across a zener diode, or fed to a control winding of a magnetic amplifier having a second control winding energized from the voltage across a zener diode. The resultant voltage is fed to a voltage regulator so as to maintain the R.M.S. value of the regulated voltage constant.
