Title: Improvements in and relating to apparatus for feeding continuous webs of stationery
Inventor: GARWOOD VICTOR WILLIAM
IPC: B41J11/24
Filed: 1955-01-06
Abstract: 789,605. Typewriters &c. LAMSON PARAGON, Ltd. Jan. 6, 1956 [Jan. 6, 1955], No. 479/55. Class 100(4)  To feed continuous webs through a tabulator or the like machine, a solenoid is provided as a secondary feeding means to augment the primary feed at least to overcome the initial inertia of the webs. As shown, the webs a are fed by tractor units 7, 8 driven from a platen 6 as described in Specification 757,302, while a solenoid 18, driving through gears 19, 19a, 17, provides the secondary feed. The solenoid is energized by an impulse from the tabulator whenever its driving mechanism is or is about to be operated either for line spacing or a long feed, and it may be of a type to give a rotary movement which is transmitted to a shaft by a series of dogs or only an axial movement which is transmitted by a pivoted pawl and ratchet wheel. If carbon webs are fed separately, a solenoid may be provided to assist their primary feed mechanism. In a modification, the solenoid, acting through a pawl, may be prevented from engaging more than one tooth from the end of its movement by a masking shield during line spacing, while the shield is withdrawn when a long feed is to be effected so that the solenoid is effective for two or three teeth. Reference has been directed by the Comptroller to Specification 757,302.

Abstract: 892,033. Grinding. CINCINNATI MILLING MACHINE CO. Jan. 8, 1960 [June 24, 1959], No. 719/60. Class 60. [Also in Group XIX] A machine tool comprises a forming member 12 such as a grinding wheel, means 60 to drive a workpiece 20 in an operating position, a gauge head having a body portion 29 pivotally mounted adjacent the operating position of the workpiece and means 42 connected to the body portion and adapted to engage the workpiece in the operating position to locate a sensing element 51 carried on the body portion in fixed relation to the means 42 to detect movement of the workpiece surface relative to the sensing element. The body portion of the gauge is pivotally mounted on an adjustable support 25 mounted on the machine slide 10 and is formed with a pair of arms 31, 32 each of which carries a sensing element consisting of a tubular member 51 carried by a sleeve 47 secured to an arm and connected by gauges 56, 57 and variable restrictions 55, 58 to a source of pneumatic pressure. The machine has a pair of arms 14, 15 which operate to remove a finished workpiece from, and at the same time carry a workpiece to be ground into, the operating position. During this movement away from the operating position, the finished workpiece pivots the gauge head to an open position where it is retained by a spring detent 37 until the new workpiece engages the sleeve 47 on the arm 31 and moves the body portion towards its operative position. The new workpiece continues its movement until it contacts an adjustable support 62 and the locating means 42 which it engages at at least two points C, D. The locating means positions the sensing members equidistant from the surface of the workpiece. The ends of the sleeves 47 are slotted and adjusted by screws 50 to a position approximately 0.0025 inches from the workpiece surface. The ends of the members 53 are approximately 0.0005 inches from the ends of the sleeves. The workpiece is rotated by a magnetic chuck 60, the axis of which is displaced from the rotational axis of the workpiece so that the latter is constantly urged against the locating means 42 and support 62. As the workpiece is ground, its size is indicated on the gauge 57 and when its finished size is reached, the pneumatic system may automatically control the retraction of the grinding wheel or some other function. In an alternative embodiment, the sensing element consists of a finger 153a, Fig. 7, which engages the surface of the workpiece and controls a variable restriction.

Title: Improvements in or relating to pressure fed lubricating systems
IPC: F01M1/26
Filed: 1937-01-12
Abstract: 490,521. Force - feed lubrication. PAUL, D. W. F. D., REES, C. L., and LUSH, G. R. W. Jan. 12, 1937, No. 926. [Class 12 (iii)] [Also in Groups XXXVII and XXVII] A switch operative on fall of lubrication pressure for breaking the ignition circuit of an internal-combustion engine or giving an alarm, is actuated by a device in which the lubrication pressure is opposed by a variable counterpressure sensitive to engine speed or suction. The switch comprises three chambers A, B and C bolted together of which C contains a diaphragm 8 carrying a headed plunger 14, 15 which is raised against the pressure of spring 7 by oil pressure from the lubricating system transmitted through pipe 11 to the underside of diaphragm 8. With oil pressure of sufficient magnitude, a contact 6 bridges contacts 1 and 2 to close the switch. Acting on a plate 22 against this movement is the difference between atmospheric pressure acting above a diaphragm 18 in chamber A and the reduced pressure below diaphragm 18 equal to the carburetter suction pressure. Needle valves 26 and 29a control outlet 25 to the atmosphere and connection 29 to the source of suction respectively. At starting the suction is small and the oil pressure required to close the switch is low, but as the speed increases, the pressure of oil required to close the switch increases. Modifications are described wherein a force proportional to engine speed acting against the oil pressure may be obtained with the suction effect replaced by oil pumped to the upperside of diaphragm 18 by an engine driven pump, a spring finger screwed down by a governor operated lever, or by a bimetallic strip heated by current from an engine driven dynamo. A further modification includes contacts closed to give a visual or audible warning before the ignition circuit is opened. Specification 485,944 is referred to.

Title: Compensation method to correct thermally induced off-track errors in disc drives
Inventor: KRAUSE JAMES N
IPC: G11B5/55
Filed: 1994-05-19
Abstract: A thermal test track (- 3) is provided outside the user-accessible area on the disc. A track complete of a known frequency is then written on either side of this thermal test track, preferably half the usual track separate distance away. To develop a thermal compensation constant, the transducer (10) is moved to the thermal test track with no compensation applied. This way, any thermally induced off-track error, which would affect seeks to user-accessible data tracks, will be reflected in the off-track from the nominal position of the thermal test track. The transducer is now moved in a series of defined increments (e.g. 5) smaller than normal track-to-track steps, or "micro-steps", away from the uncompensated position of the thermal track toward one of the tracks written with the known frequency. When the data on the written track to the side of the thermal test track is detected, a note is made of the number of micro-steps the transducer has been moved. The transducer (10) is then micro-stepped incrementally in the opposite direction until the data written on the other side of the thermal test track is detected. A simple comparison of these two micro-step counts will yield the existing thermal shift, which can be converted into a thermal compensation constant for the transducer positioning mechanism by means of a simple look-up table.
